The indoor temperature is heated in advance. Therefore, the blower is controlled to operate at the first set rotation speed V1 to reduce the carbon dioxide concentration, and the compressor is controlled to operate at the first heating frequency f1 to adjust the indoor temperature back to the user's expectation. temperature.
通过上述设置方式，本发明的新风空调的控制方法能够提前基于二氧化碳的预设浓度对室内的二氧化碳浓度调整，这样就保证了室内二氧化碳浓度不会过高，当用户返回家中时，室内将会是用户所期望的二氧化碳浓度。另外，由于降低二氧化碳浓度的方式为开启新风系统，此时室外空气大量涌入室内，使室内温度骤变，相应地，新风空调会同时开启空调系统，控制压缩机以第一制热频率f1运行，使室内温度变化减小，从而在运行新风系统后，能够快速调整室内温度至用户期望的温度，避免由于引入室外新风而导致的温度变化。在检测室内的二氧化碳浓度P1和所述室内换热器的盘管温度Ta之前，新增了打分系统，避免了在用户近期回家概率不高时，仍然每天开启，造成能源浪费的情况。Through the above setting method, the control method of the fresh air conditioner of the present invention can adjust the indoor carbon dioxide concentration based on the preset concentration of carbon dioxide in advance, thus ensuring that the indoor carbon dioxide concentration will not be too high, and when the user returns home, the indoor will be User's desired carbon dioxide concentration. In addition, since the method of reducing carbon dioxide concentration is to open the fresh air system, a large amount of outdoor air floods into the room at this time, causing the indoor temperature to change abruptly. Accordingly, the fresh air air conditioner will open the air conditioning system at the same time, and control the compressor to operate at the first heating frequency f1 Operation, so that the indoor temperature change is reduced, so that after running the fresh air system, the indoor temperature can be quickly adjusted to the temperature expected by the user, and the temperature change caused by the introduction of outdoor fresh air can be avoided. Before detecting the indoor carbon dioxide concentration P1 and the coil temperature Ta of the indoor heat exchanger,a new scoring system is added to avoid the situation that the user is still turned on every day when the probability of returning home in the near future is not high, resulting in energy waste. .

具体实施方式Detailed ways
下面参照附图来描述本发明的优选实施方式。本领域技术人员应当理解的是，这些实施方式仅仅用于解释本发明的技术原理，并非旨在限制本发明的保护范围。本领域技术人员可以根据需要对其作出调整，以便适应具体的应用场合。例如，尽管说明书中是以当室外新风的PM2.5浓度F＞Fa时，控制所述送风机停止运行为例进行描述的，但是，本发明显然可以采用其它方案，例如，如果新风系统内设置有针对PM2.5的过滤模块，那么只需要放缓新风进入的速度，使过滤模块能够充分过滤新风即可。Preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principle of the present invention, and are not intended to limit the protection scope of the present invention.

There is a filter module for PM2.5, so it is only necessary to slow down the speed of fresh air entering, so that the filter module can fully filter the fresh air.
实施例一Example 1
参照图1和图2，对本发明的新风空调的控制方法进行描述。其中，图1为本发明的实施例一的新风空调的控制方法的流程图，图2为本发明的实施例一的新风空调的控制方法的逻辑图。1 and 2, the control method of the fresh air conditioner of the present invention will be described. 1 is a flowchart of a control method for a fresh air air conditioner according to Embodiment 1 of the present invention, and FIG. 2 is a logic diagram of a control method for a fresh air air conditioner according to Embodiment 1 of the present invention.
如图1所示，为解决现有的现有的新风空调不能够在停机状态下自主完成二氧化碳浓度调节的问题，本发明的新风空调包括新风系统和空调系统，新风系统包括送风机，空调系统包括压缩机和室内换热器。其中，送风机可以为新风系统的新风管内配置的轴流风机，也可以为空调系统的室内风机，该送风机的设置形式只要满足启动时能够将室外新风引入室内即可。新风空调的控制方法包括：As shown in FIG. 1, in order to solve the problem that the existing existing fresh air air conditioner cannot independently adjust the carbon dioxide concentration in a shutdown state, the fresh air air conditioner of the present invention includes a fresh air system and an air conditioning system, the fresh air system includes a blower, and the air conditioning system includes Compressor and indoor heat exchanger. The blower may be an axial flow fan configured in the fresh air duct of the fresh air system, or an indoor fan of the air conditioning system, as long as the setting form of the blower satisfies the requirement that outdoor fresh air can be introduced into the room when it is started. The control methods of fresh air conditioners include:
S100、在新风空调处于停机状态下，检测室内的二氧化碳浓度P1和室内换热器的盘管温度Ta。S100. When the fresh air air conditioner is ina shutdown state, detect the indoor carbon dioxide concentration P1 and the coil temperature Ta of the indoor heat exchanger.
例如，通过新风空调内设置的二氧化碳浓度检测装置和温度检测装置，来检测二氧化碳的浓度以及盘管温度。检测装置在本领域较为常见，例如温度计、二氧化碳感应器等，其种类繁多，不再一一列举。For example, the concentration of carbon dioxide and the temperature of the coil are detected by the carbon dioxide concentration detection device and the temperature detection device installed in the fresh air conditioner. Detection devices are relatively common in the art, such as thermometers, carbon dioxide sensors, etc., and there are many kinds of them, which will not be listed one by one.
S200、判断二氧化碳浓度P1与预设浓度Pa的大小以及盘管温度Ta与第一设定温度T1的大小；S200, determine the size of the carbon dioxide concentration P1 and the preset concentration Pa and the size of the coil temperature Ta and the first set temperature T1 ;
对二氧化碳浓度P1以及盘管温度Ta与预设浓度Pa和第一设定温度T1进行大小的判断，来确认室内二氧化碳浓度是否超标、室内温度是否能够达到要求。其中，预设浓度可以为Pa＝500PPM，设定温度可以为T1＝20℃。需要说明的是，当新风空调运行时，室内的温度与盘管温度是呈正相关的，即盘管温度越高，室内的温度越高，所以本发明的控制方法是通过控制盘管温度Ta来实现控制室内温度的。因此需要设置一个合理的第一设定温度值，以使得在耗电量可以接受的前提下，使室内不至于过冷即可。例如，第一设定温度T1是可以根据室外环境温度来确定。Determine whether the carbon dioxide concentration P1, the coil temperature Ta , the preset concentration Pa and thefirst set temperature T1 are determined to confirm whether the indoor carbon dioxide concentration exceeds the standard and whether the indoor temperature can meet the requirements. Wherein, the preset concentration may be Pa= 500PPM, and the set temperature may be T1 =20°C. It should be noted that when the fresh air conditioner is running, the indoor temperature is positively correlated with the coil temperature, that is, the higher the coil temperature, the higher the indoor temperature, so the control method of the present invention is to control the coil temperature Ta to control the indoor temperature. Therefore, it is necessary to set a reasonable first set temperature value, so that the room will not be too cold under the premise that the power consumption is acceptable. For example, thefirst set temperature T1 may be determined according to the outdoor ambient temperature.
S300、当P1≥Pa且Ta＜T1时，控制送风机以第一设定转速V1运行，并且控制压缩机以第一制热频率f1运行。S300. When P1 ≥ Pa and Ta< T1 , control the blower to run at the first set rotational speed V1 , and control the compressor to run at the first heating frequency f1 .
上述设置方式的优点在于：当P1≥Pa且Ta＜T1时，室内的二氧化碳浓度已经超标，在寒冷的冬季，室内温度也未达到用户期望的温度。此时，通过启动送风机和压缩机，使室内二氧化碳浓度降低的同时，对室内温度进行调节，确保室内温度不至于过冷，降低了新风系统带来的温度变化，在新风系统完成二氧化碳浓度调节后，室内温度也会被调节回用户期望的值，保证用户在进入室内时体感较为舒适。The advantages of the above arrangement are: when P1 ≥ Pa and Ta< T1 , the indoor carbon dioxide concentration has exceeded the standard, and the indoor temperature has not reached the user's desired temperature in cold winter. At this time, by starting the blower and compressor, the indoor carbon dioxide concentration is reduced, and the indoor temperature is adjusted to ensure that the indoor temperature will not be too cold, which reduces the temperature change caused by the fresh air system. After the fresh air system completes the adjustment of the carbon dioxide concentration , the indoor temperature will also be adjusted back to the value expected by the user to ensure that the user feels more comfortable when entering the room.
本领域技术人员能够理解的是，在送风机为新风空调的室内风机的情况下，只需开启送风机即可实现二氧化碳浓度调节和室内温度调节；在送风机为新风管内配置的单独的轴流风机的情况下，如需对室内温度进行调节，还需要开启与室内换热器相匹配的室内风机。Those skilled in the art can understand that when the blower is the indoor fan of the fresh air air conditioner, the carbon dioxide concentration adjustment and indoor temperature adjustment can be realized only by turning on the blower; when the blower is a separate axial flow fan configured in the fresh air duct If the indoor temperature needs to be adjusted, the indoor fan matching the indoor heat exchanger needs to be turned on.
下面进一步参照图1和图2，对本发明的进行详细描述。The present invention will be described in detail below with further reference to FIG. 1 and FIG. 2 .
如图1和图2所示，在一种可能的实施方式中，在S300 步骤之后，所述控制方法还包括：As shown in FIG. 1 and FIG. 2, in a possible implementation manner, after step S300, the control method further includes:
间隔设定时间T1后，检测室内二氧化碳浓度P2，判断室内二氧化碳浓度P2与预设浓度Pa的大小，基于判断结果，控制所述新风系统和所述空调系统的运行状态；After the interval set time T1, the indoor carbondioxide concentration P2 is detected, the sizeof the indoor carbondioxide concentration P2 and the preset concentrationPa is judged, and based on the judgment result, the operating states of the fresh air system and the air conditioning system are controlled;
其中，当P1＞P2≥Pa时，维持所述新风系统状态不变，并相应地控制所述压缩机以第二制热频率f2运行，f2＞f1；Wherein, when P1 >P2 ≥Pa , keep the state of the fresh air system unchanged, and control the compressor to operate at the second heating frequency f2 accordingly, where f2 >f1 ;
其中，当P2≥P1≥Pa时，控制所述送风机以第二设定风速 V2运行，并相应地控制所述压缩机以第三制热频率f3运行，V2＞V1， f3＞f1；Wherein, when P2 ≥ P1 ≥ Pa , the blower is controlled to run at the second set wind speed V2 , and the compressor is correspondingly controlled to run at the third heating frequency f3 , V2 >V1 , f3 >f1 ;
其中，当P2＜Pa时，控制所述送风机停止运行。Wherein, when P2 <Pa , the blower is controlled to stop running.
上述设置方式的优点在于：由于新风系统的开启，室内的二氧化碳浓度是不断变化的，此时就要每隔设定时间T1后(如 T1＝2min)，重新确认二氧化碳浓度的变化，来重新判断新风系统和空调系统的运行状态，避免二氧化碳浓度已经正常，还在开启新风，造成室内温度降低，压缩机持续工作，进而造成能源的浪费；或者是由于新风系统开启功率不足，由于室内宠物等较多，二氧化碳浓度反而越来越高的情况。为了避免上述情况的发生，每间隔设定时间T1后，检测室内二氧化碳浓度P2，判断室内二氧化碳浓度P2与预设浓度Pa的大小。The advantage of the above setting method is that due to the openingof the fresh air system, the carbon dioxide concentration in the room is constantly changing. Re-judg the operation status of the fresh air system and air conditioning system to avoid that the carbon dioxide concentration is normal, and the fresh air is still turned on, causing the indoor temperature to drop and the compressor to continue to work, thereby causing energy waste; or due to insufficient opening power of the fresh air system. The more time you wait, the higher the carbon dioxide concentration. In order to avoid the above situation, after every set time T1, the indoor carbondioxide concentration P2 is detected, and the sizeof the indoor carbondioxide concentration P2 and the preset concentrationPa is determined.
当P1＞P2≥Pa时，说明新风系统开启后，二氧化碳浓度确实得到了降低，但还未达到预设浓度Pa，此时新风系统的功率足够，但由于开启了T1时间的新风系统，室内温度会有所降低，继续开启新风系统的话，第一制热频率f1此时已经对于温度补偿有所不足，因此，相应地控制压缩机以第二制热频率f2运行，f2＞f1，增大压缩机的频率，使室内温度维持在一个用户的期望值附近。When P1 >P2 ≥Pa , it means that after the fresh air system is turned on, the carbon dioxide concentration has indeed been reduced, but it has not reached the preset concentrationPa . At this time, the power of the fresh air system is sufficient, but due to the opening of the T1 time In the fresh air system, the indoor temperature will decrease to some extent. If the fresh air system continues to be turned on, the first heating frequency f1 is already insufficient for temperature compensation. Therefore, the compressor is controlled to operate at the second heating frequency f2 accordingly. If f2 >f1 , increase the frequency of the compressor to keep the indoor temperature around a user's desired value.
当P2≥P1≥Pa时，说明室内的二氧化碳浓度反而比开启之前更高，也就是室内二氧化碳产生的比较多，此时就需要加大新风系统的运行速度，使送风机以第二设定风速V2运行，V2＞V1。送风量增大，相应地室内温度也会下降的更快，因此，控制压缩机以第三制热频率f3运行，f3＞f1，用于对室内温度作出补偿。When P2 ≥P1 ≥ Pa , it means that the indoor carbon dioxide concentration is higher than before opening, that is, more indoor carbon dioxide is generated. At this time, it is necessary to increase the operating speed of the fresh air system, so that the blower is set at the second setting. The constant wind speed V2 runs, V2 >V1 . As the air supply volume increases, the indoor temperature will drop faster accordingly. Therefore, the compressor is controlled to operate at the third heating frequency f3 , where f3 >f1 , to compensate the indoor temperature.
当P2＜Pa时，说明室内二氧化碳浓度已经达到较为适宜的浓度值，控制送风机停止运行。此时，压缩机仍然会维持制热频率不变，工作一段时间，直至盘管温度Ta≥T1时停止运行。When P2 <Pa , it means that the indoor carbon dioxide concentration has reached a more suitable concentration value, and the blower is controlled to stop running. At this time, the compressor will still keep the heating frequency unchanged and work for a period of time until the coil temperature Ta ≥ T1 and stop running.
如图2所示，在另一种可能的实施方式中，在“控制送风机以第一设定转速V1运行，并且控制压缩机以第一制热频率f1运行”的步骤之前、同时或之后，控制方法还包括：检测室外新风的PM2.5 浓度F，判断PM2.5浓度F与预设浓度Fa的大小，当F＞Fa时，控制送风机停止运行，当F≤Fa时，检测新风空调是否处于停机状态，在新风空调处于停机状态下，检测室内的二氧化碳浓度P1和室内换热器的盘管温度Ta。As shown in FIG. 2, in another possible implementation manner, before, at the same time or at the step of “controlling the blower to operate at thefirst set rotational speed V1, and controlling the compressor to operate at thefirst heating frequency f1” After that, the control method further includes: detecting the PM2.5 concentration F of the outdoor fresh air, judging the size of the PM2.5 concentration F and the preset concentration Fa, when F>Fa , controlling the blower to stop running, whenF≤Fa , to detect whether the fresh air conditioner is in a shutdown state, and when the fresh air air conditioner is ina shutdown state, detect the indoor carbon dioxide concentration P1 and the coil temperature Ta of the indoor heat exchanger.
上述设置方式的优点在于：首先通过判断室外新风的 PM2.5的浓度，来确定室外新风是否适宜引入室内，如果室外新风的 PM2.5浓度过高，说明室外目前是重度污染情况，此时将空气引入室内，反而会更加降低室内空气质量，因此，在这种情况下即使室内二氧化碳浓度较高也选择不开启新风系统，只有当室外空气低于PM2.5 的预设浓度Fa才考虑将室外新风引入。本发明是在新风空调处于停机状态下控制新风空调完成的上述操作，这样能够使用户不在家时，提前自动调节好室内二氧化碳浓度和室内温度，完成智能控制。The advantage of the above setting method is that: first, by judging the PM2.5 concentration of the outdoor fresh air, it is determined whether the outdoor fresh air is suitable to be introduced into the room. If the PM2.5 concentration of the outdoor fresh air is too high, it means that the outdoor is currently heavily polluted. If the air is introduced into the room, it will further reduce the indoor air quality. Therefore, in this case, even if the indoor carbon dioxide concentration is high, the fresh air system will not be turned on. Only when the outdoor air is lower than the preset concentrationFa of PM2.5 will it be considered. Outdoor fresh air is introduced. The present invention controls the fresh air air conditioner to complete the above operations when the fresh air air conditioner is in a shutdown state, so that when the user is not at home, the indoor carbon dioxide concentration and indoor temperature can be automatically adjusted in advance to complete intelligent control.
在另一种可能的实施方式中，“在所述新风空调处于停机状态下，检测室内的二氧化碳浓度P1和所述室内换热器的盘管温度Ta”的步骤之后，所述控制方法还包括：检测室外环境温度Tao；判断室外环境温度Tao与盘管温度Ta的大小；当Tao≥Ta时，控制压缩机停止运行。当室外环境温度Tao大于或等于盘管温度Ta时，证明室外环境温度较高，此时引入室外新风对室内温度影响不大，无需启动制热功能。In another possible implementation manner, after the step of “detecting the indoor carbon dioxide concentration P1 and the coil temperature Ta of the indoor heat exchanger when the fresh air conditioner is ina shutdown state”, the control method It also includes: detecting the outdoor ambient temperature Tao ; judging the size of the outdoor ambient temperature Tao and the coil temperature Ta ; when Tao ≥ Ta , controlling the compressor to stop running. When the outdoor ambient temperature Tao is greater than or equal to the coil temperature Ta , it proves that the outdoor ambient temperature is relatively high. At this time, the introduction of outdoor fresh air has little effect on the indoor temperature, and the heating function does not need to be activated.
当接收到制热指令后，说明此时用户需要对其进行操作，此时用户已经处于较为舒适的环境中了，这些功能将不再运行，而是依据用户的指令进行操作。After receiving the heating command, it means that the user needs to operate it at this time, and the user is already in a more comfortable environment, and these functions will no longer operate, but operate according to the user's instructions.
综上所述，本发明通过在新风空调停机状态下，对新风空调进行二氧化碳浓度调节的自动控制，解决了现有的新风空调不能够在停机状态下自主完成二氧化碳浓度调节的问题。通过增加对压缩机的运行频率的控制，使新风空调在自主调节二氧化碳浓度的同时，室内温度变化较小，在二氧化碳浓度调节完之后，能够自主将室内温度调整至较为适宜的温度值。通过增加在每隔T1时间后重复检测，使室内能够一直保持较好的二氧化碳浓度和温度，并且能够基于前后对比的二氧化碳浓度值，进行针对性地送风机风速调整和压缩机制热频率调整，节约电源。增加PM2.5的判定，使新风空调能够根据室外环境选择判断是否开启新风系统。增加盘管温度Ta与室外环境温度Tao的判定，使新风空调能够选择性地开启压缩机，避免不必要的电量浪费。To sum up, the present invention solves the problem that the existing fresh air air conditioner cannot automatically adjust the carbon dioxide concentration in the shutdown state by automatically controlling the carbon dioxide concentration adjustment of the fresh air air conditioner when the fresh air air conditioner is stopped. By increasing the control of the operating frequency of the compressor, the fresh air air conditioner can adjust the carbon dioxide concentration independently, while the indoor temperature changes less. After the carbon dioxide concentration is adjusted, the indoor temperature can be adjusted to a more suitable temperature value. By increasing the repeated detection after every T1 time, the indoor carbon dioxide concentration and temperature can be maintained at a good level, and based on the carbon dioxide concentration value compared before and after, the air speed of the blower and the heating frequency of the compressor can be adjusted in a targeted manner, saving energy. power supply. Increase the determination of PM2.5, so that the fresh air conditioner can choose whether to open the fresh air system according to the outdoor environment. Increase the determination of the coil temperature Ta and the outdoor ambient temperature Tao , so that the fresh air conditioner can selectively turn on the compressor and avoid unnecessary waste of electricity.
需要说明的是，上述实施方式仅仅用来阐述本发明的原理，并非旨在与限制本发明的保护范围，在不偏离本发明原理的条件下，本领域技术人员能够对上述结构进行调整，以便本发明能够应用于更加具体的应用场景。It should be noted that the above embodiments are only used to illustrate the principles of the present invention, and are not intended to limit the protection scope of the present invention. Those skilled in the art can adjust the above structures without departing from the principles of the present invention, so as to The present invention can be applied to more specific application scenarios.
例如，在一种可替换的实施方式中，“间隔设定时间T1后，检测室内二氧化碳浓度P2，判断室内二氧化碳浓度P2与预设浓度 Pa的大小，基于判断结果，控制所述新风系统和所述空调系统的运行状态”步骤中，还可以是当P2≥Pa时，说明二氧化碳浓度还是过高，此时只需维持所述新风系统状态不变，而不去控制所述压缩机的频率，当然，其相应地也就只有调节空气内二氧化碳浓度的作用，而不具有同时调节室内温度的作用。For example, inan alternative embodiment, "after the interval set time T1, the indoor carbondioxide concentration P2 is detected, the size of the indoor carbondioxide concentration P2 and the preset concentrationPa is determined, and based on the determination result, the In the operation state of the fresh air system and the air conditioning system”, it can also be that when P2 ≥ Pa , it means that the carbon dioxide concentration is still too high, and at this time, it is only necessary to maintain the state of the fresh air system, without controlling all the conditions. The frequency of the compressor, of course, correspondingly only has the effect of adjusting the concentration of carbon dioxide in the air, and does not have the effect of adjusting the indoor temperature at the same time.
例如，在另一种可替换的实施方式中，当室外新风的 PM2.5的浓度F超出预设浓度Fa时，此时如果新风系统内设置有针对 PM2.5的过滤模块，那么只需要放缓新风进入的速度，使过滤模块能够充分过滤新风即可，也并不是必须要控制送风机停止运行。For example, in another alternative embodiment, when the concentration F of PM2.5 in the outdoor fresh air exceeds the preset concentration Fa, ifa filter module for PM2.5 is provided in the fresh air system at this time, then only It is enough to slow down the speed of fresh air entering so that the filter module can fully filter the fresh air, and it is not necessary to control the blower to stop running.
例如，虽然本发明的控制方法是结合冬季制热模式进行说明的，但是本领域技术人员能够理解的是，只要将相应的参数和判断条件进行调整，本发明的原理显然也可以适用于夏季制冷模式。For example, although the control method of the present invention is described in conjunction with the heating mode in winter, those skilled in the art can understand that as long as the corresponding parameters and judgment conditions are adjusted, the principle of the present invention can obviously also be applied to cooling in summer model.
上述实施例中虽然将各个步骤按照上述先后次序的方式进行了描述，但是本领域技术人员可以理解，为了实现本实施例的效果，不同的步骤之间不必按照这样的次序执行，其可以同时(并行)执行或以颠倒的次序执行，例如PM2.5的浓度F与预设浓度Fa的判定，是可以和室内温度T与第二设定温度T2的判定的顺序颠倒的，这些简单的变化都在本发明的保护范围之内。Although the various steps are described in the above-mentioned order in the above-mentioned embodiment, those skilled in the art can understand that, in order to achieve the effect of this embodiment, different steps need not be performed in such an order, which can be performed simultaneously ( In parallel) or in reverse order, for example, the determination of PM2.5 concentration F and preset concentration Fa can be reversed from the order of determination of indoor temperature T and second set temperature T2 , these simple Variations are all within the protection scope of the present invention.
在实施例一中，主要介绍如何控制新风空调，使得用户在下班回家后，室内能够保持较低的二氧化碳浓度和较舒适的温度。但是，空调系统不适宜一直开启，全天候调节室内温度，只有在用户即将到家之前一段时间开启，才能更加高效地利用电能，防止能源的浪费，特别是对温度的控制，由于耗电量大，更需要对其进行精确控制。In the first embodiment, how to control the fresh air conditioner is mainly introduced, so that the user can maintain a lower carbon dioxide concentration and a more comfortable temperature in the room after returning home from get off work. However, it is not suitable for the air-conditioning system to be turned on all the time to adjust the indoor temperature around the clock. Only when the user is about to get home for a period of time can the electric energy be used more efficiently and the waste of energy can be prevented, especially the temperature control. It needs to be precisely controlled.
现有技术中通常是用户设定一个预设开机时刻，如下午 6:00，新风空调设定一个固定的二氧化碳浓度和室内温度调节时间，如 30min，以此来确定提前开启时刻，如根据预设开机时刻为下午6:00，固定的空气调节时间为30min，那么提前开启时刻就是下午5:30。In the prior art, the user usually sets a preset start-up time, such as 6:00 pm, and the fresh air conditioner sets a fixed carbon dioxide concentration and indoor temperature adjustment time, such as 30 minutes, to determine the early start time, such as according to the preset time. Assuming the start-up time is 6:00 pm, and the fixed air conditioning time is 30 minutes, then the early start-up time is 5:30 pm.
但是，由于用户每次的预设开机时刻并不是均为6:00，也就是用户并不是每次都是6:00到家，这样的话，就可能会造成提前开启，浪费能源，延后开启，用户体验不佳的情况。并且，在固定的空气调节时间30min内，如果不参照外部环境，也并不一定能够每次均准时完成调节，进而对提前开启时刻作出误判，同样可能造成浪费能源或用户体验不佳的情况。However, since the preset boot time of the user is not always at 6:00, that is, the user does not always arrive home at 6:00. In this case, it may result in early startup, waste of energy, and delayed startup. Bad user experience. In addition, within a fixed air conditioning time of 30 minutes, if you do not refer to the external environment, you may not be able to complete the adjustment on time every time, and then make a misjudgment about the early opening time, which may also lead to waste of energy or poor user experience. .
那么，如何准确确定预设开机时刻，以及如何保证固定的空气调节时间，通过这两者来保证提前开启时刻的准确性，将在实施例二至实施例四中重点阐述。Then, how to accurately determine the preset power-on time and how to ensure a fixed air conditioning time, so as to ensure the accuracy of the early start-up time, will be mainly explained in the second embodiment to the fourth embodiment.
实施例二Embodiment 2
为了解决现有的预设开机时刻以及空气调节时间均不够精确的问题，本发明在实施例一中的S100步骤之前增加了对于预设开机时刻和空气调节时间的补偿。In order to solve the problem that the existing preset startup time and air conditioning time are not accurate enough, the present invention adds compensation for the preset startup time and air conditioning time before step S100 in the first embodiment.
参见图3，其中，图3为本发明的实施例二的新风空调的控制方法的流程图。Referring to FIG. 3 , wherein, FIG. 3 is a flowchart of a control method for a fresh air conditioner according to Embodiment 2 of the present invention.
如图3所示，在一种较佳的实施方式中，新风空调的控制方法还包括：As shown in Figure 3, in a preferred embodiment, the control method of the fresh air conditioner further includes:
S110、获取新风空调的预设开机时刻和室外环境温度。S110. Acquire the preset startup time of the fresh air conditioner and the outdoor ambient temperature.
本实施方式中的预设开机时刻可以是用户主动设置的开机时刻，也可以是基于新风空调的历史开机时刻统计得出的开机时刻。例如预设开机时刻可以是用户通过遥控器、手机APP等方式设定的开机时刻，或者新风空调的控制器或云端服务器根据新风空调的历史实际开机时刻统计得出的开机时刻，如利用统计学方法和概率论计算等方法对新风空调的历史实际开机时刻进行统计计算得出的历史实际开机时刻的平均值，并将该平均值作为本次新风空调的预设开机时刻。下文将以云端服务器进行统计计算为例对本控制方法进行阐述。The preset power-on time in this embodiment may be a power-on time actively set by a user, or may be a power-on time based on statistics of historical power-on times of the fresh air conditioner. For example, the preset start-up time may be the start-up time set by the user through the remote control, mobile phone APP, etc., or the start-up time obtained by the controller or cloud server of the fresh air air conditioner according to the historical actual start-up time of the fresh air air conditioner. The average value of the historical actual start-up time is obtained by statistical calculation of the historical actual start-up time of the fresh air air conditioner, and the average value is used as the preset start-up time of the fresh air air conditioner. The present control method will be described below by taking the statistical calculation performed by the cloud server as an example.
S111、基于时间修正参数，修正预设开机时刻。S111 , correcting the preset power-on time based on the time correction parameter.
时间修正参数用于表征预设开机时刻与实际开机时刻之间的对应关系，也即用户设定的或计算出的预设开机时刻与实际开机时刻之间的偏差。在用户设定或新风空调计算出预设开机时刻后，基于时间修正参数对该开机时刻进行修正，如在确定出的预设开机时刻的基础上通过增加或减少一个时间段的方式对预设开机时刻进行修正，可以使得修正后的预设开机时刻更加接近用户的真实开机时间。例如，预设开机时刻为18:00，时间修正参数为+10min，那么修正后的预设开机时刻为 18:00+10min＝18:10。The time correction parameter is used to represent the corresponding relationship between the preset power-on time and the actual power-on time, that is, the deviation between the preset power-on time set or calculated by the user and the actual power-on time. After the user sets the preset startup time or the fresh air conditioner calculates the preset startup time, the startup time is corrected based on the time correction parameter. Correcting the booting time can make the corrected preset booting time closer to the actual booting time of the user. For example, the preset power-on time is 18:00, and the time correction parameter is +10min, then the corrected preset power-on time is 18:00+10min=18:10.
在一种优选的实施方式中，时间修正参数为新风空调上一次运行时确定的。具体地，在新风空调上一次接收到开机指令运行时，如前一天的相同时段或前几天的相同时段新风空调接收开机指令时，首先记录当前实际开机时刻，然后将本次以前(包括本次)设定天数内的历史预设开机时刻和历史实际开机时刻进行统计，并分别计算设定天数内的历史预设开机时刻的均值和历史实际开机时刻的均值。然后计算历史实际开机时刻的均值与历史预设开机时刻的均值之间的第一差值，并将该第一差值作为时间修正参数进行存储，供下一次修正预设开机时刻使用。In a preferred embodiment, the time correction parameter is determined during the last operation of the fresh air conditioner. Specifically, when the fresh air conditioner received a start-up command last time, such as the same period of the previous day or the same period of the previous day, when the fresh air conditioner received the start-up instruction, the current actual start-up time was first recorded, and then the previous (including the current time) times) The historical preset power-on time and the historical actual power-on time within the set number of days are counted, and the average value of the historical preset power-on time and the historical actual power-on time within the set number of days are calculated respectively. Then, the first difference between the mean value of the historical actual power-on time and the mean value of the historical preset power-on time is calculated, and the first difference is stored as a time correction parameter for the next correction of the preset power-on time.
举例而言，云端服务器统计新风空调包括本次在内的过去7 天的同一时段(如18:00-19:00)的历史预设开机时刻和历史实际开机时刻，并计算所有历史预设开机时刻的均值和所有历史实际开机时刻的均值，如历史预设开机时刻的均值计算出为18:30，历史实际开机时刻的均值计算出为18:40，那么第一差值等于18:40-18:30＝10min，也就是说，时间修正参数为10min，也即在过去7天内，用户的实际开机时刻比预设开机时刻平均晚了10min。由此，在下一次预估预设开机时刻时，通过计算预估出的预设开机时刻与时间修正参数的总和作为修正后的预设开机时刻，从而提升预设开机时刻的预估精准度，减少能源浪费，提升用户体验。当然，上述举例中时间修正参数是以正数为例进行说明的，如果求得的时间修正参数为负数，本控制方法同样成立。如时间修正参数为 -10min，那么表示过去7天内用户的实际开机时刻比预设开机时刻平均早了10min，由此在下一次预估预设开机时刻时，通过计算预设开机时刻与时间修正参数的总和，即预设开机时刻减去10min作为修正后的预设开机时刻，同样可以提升预设开机时刻的预估精准度。For example, the cloud server counts the historical preset power-on time and historical actual power-on time of the fresh air conditioner during the same period (such as 18:00-19:00) in the past 7 days including this time, and calculates all historical preset power-on times. The average value of the time and the average value of all historical actual start-up times, if the average value of the historical preset start-up time is calculated as 18:30, and the average value of the historical actual start-up time is calculated as 18:40, then the first difference is equal to 18:40- 18:30=10min, that is to say, the time correction parameter is 10min, that is, in the past 7 days, the user's actual power-on time is 10min later than the preset power-on time on average. Therefore, when estimating the preset power-on time next time, the sum of the estimated preset power-on time and the time correction parameter is calculated as the corrected preset power-on time, thereby improving the estimation accuracy of the preset power-on time. Reduce energy waste and improve user experience. Of course, the time correction parameter in the above example is described by taking a positive number as an example. If the obtained time correction parameter is a negative number, the control method is also valid. If the time correction parameter is -10min, it means that the actual boot time of the user in the past 7 days is 10min earlier than the preset boot time on average. Therefore, when the preset boot time is estimated next time, the preset boot time and time correction parameters are calculated by calculating The sum of , that is, the preset power-on time minus 10 minutes is used as the corrected preset power-on time, which can also improve the estimated accuracy of the preset power-on time.
S112、基于室外环境温度，确定空气调节时间。S112. Determine the air conditioning time based on the outdoor ambient temperature.
在获取新风空调的预设开机时刻的同时、之前或之后，获取新风空调所在位置的室外环境温度，如通过设置于室外机的温度传感器等采集室外环境温度；然后基于室外环境温度，确定空气调节时间，如在确定室外环境温度后，云端服务器基于室外环境温度计算出与该室外环境温度相匹配的空气调节时间。At the same time, before or after obtaining the preset startup time of the fresh air conditioner, obtain the outdoor ambient temperature of the location where the fresh air conditioner is located, such as collecting the outdoor ambient temperature through a temperature sensor installed on the outdoor unit; then determine the air conditioning based on the outdoor ambient temperature time, for example, after determining the outdoor ambient temperature, the cloud server calculates the air conditioning time that matches the outdoor ambient temperature based on the outdoor ambient temperature.
较为优选的，可以基于室外环境温度与空气调节时间之间的拟合公式，计算空气调节时间。例如，采用如下公式(1)计算空气调节时间：More preferably, the air conditioning time may be calculated based on a fitting formula between the outdoor ambient temperature and the air conditioning time. For example, the following formula (1) is used to calculate the air conditioning time:
t＝k×Tao+b (1)t=k×Tao+b (1)
公式(1)中，t代表空气调节时间，Tao为室外环境温度， k和b为常数，该常数可以基于实验数据拟合得出。例如，针对不同室外环境温度和空气调节时间进行多次对照实验，从而建立空气调节时间与室外环境温度的线性关系。In formula (1), t represents the air conditioning time, Tao is the outdoor ambient temperature, and k and b are constants, which can be obtained by fitting based on experimental data. For example, multiple control experiments are carried out for different outdoor ambient temperatures and air conditioning times to establish a linear relationship between air conditioning time and outdoor ambient temperature.
当然，空气调节时间的确定还可以基于室外环境温度与空气调节时间的其他关系进行，如基于室外环境温度与空气调节时间固定对应关系确定等。如基于空气调节试验确定出室外环境温度与空气调节时间的对照表，利用该对照表确定室外环境温度确定的空气调节时间。Of course, the determination of the air conditioning time may also be performed based on other relationships between the outdoor ambient temperature and the air conditioning time, such as determination based on a fixed correspondence between the outdoor ambient temperature and the air conditioning time. For example, a comparison table between the outdoor ambient temperature and the air conditioning time is determined based on the air conditioning test, and the air conditioning time determined by the outdoor ambient temperature is determined by using the comparison table.
上述设置方式的优点在于：由于不同的室外环境温度对新风空调的空气调节能力有很大的影响，因此通过利用室外环境温度与空气调节时间之间的拟合公式或对应关系确定空气调节时间，能够保证空气调节时间的精确性，避免能源被过度浪费。The advantages of the above setting method are: since different outdoor ambient temperatures have a great influence on the air conditioning capacity of the fresh air conditioner, the air conditioning time is determined by using the fitting formula or corresponding relationship between the outdoor ambient temperature and the air conditioning time. It can ensure the accuracy of air conditioning time and avoid excessive waste of energy.
S113、基于空气调节时间和修正后的预设开机时刻，确定提前开启时刻；S113, determining the early start time based on the air conditioning time and the corrected preset start time;
基于修正后的预设开机时刻和经过室外环境温度补偿后的空气调节时间，计算新风空调的提前开启时刻；在修正预设开机时间后，空气调节模式的开启时刻就可以基于空气调节时间确定。例如，新风空调的空气调节时间为5min，则在修正后的预设开机时刻为18:10时，提前开启时刻为18:05。Based on the corrected preset startup time and the air conditioning time after compensation for the outdoor ambient temperature, the early startup time of the fresh air conditioner is calculated; after the preset startup time is corrected, the startup time of the air conditioning mode can be determined based on the air conditioning time. For example, if the air conditioning time of the fresh air conditioner is 5 minutes, then when the revised preset start time is 18:10, the advance start time is 18:05.
S114、在到达所述提前开启时刻时，开启S100步骤。S114. When the advance start time is reached, start step S100.
当时间到达提前开启时刻时，控制新风空调开始对室内的二氧化碳浓度和室内温度进行调节。When the time reaches the early opening time, the control of the fresh air conditioner starts to adjust the indoor carbon dioxide concentration and indoor temperature.
通过上述描述可以看出，本发明的新风空调的控制方法能够提基于时间修正参数对预设开机时刻进行修正，提升时间预估的精确度。具体而言，通过基于时间修正参数，修正预设开机时刻，本发明的控制方法能够基于用户的开机习惯对预设开机时刻进行修正，从而使修正后的预设开机时刻与用户的真实开机时间更加接近，做到针对单个用户的精确化和个性化对待，提高用户体验。另外，本发明基于室外环境温度对空气调节时间进行确定，由于不同的室外环境温度对新风空调的空气调节能力有很大的影响，因此通过利用室外环境温度与空气调节时间之间的拟合公式或对应关系确定空气调节时间，进一步保证空气调节时间的精确性，避免能源被过度浪费。It can be seen from the above description that the control method of the fresh air conditioner of the present invention can correct the preset power-on time based on the time correction parameter, thereby improving the accuracy of time estimation. Specifically, by correcting the preset power-on time based on the time correction parameter, the control method of the present invention can correct the preset power-on time based on the user's power-on habit, so that the corrected preset power-on time is the same as the user's real power-on time. Get closer, achieve precise and personalized treatment for individual users, and improve user experience. In addition, the present invention determines the air conditioning time based on the outdoor ambient temperature. Since different outdoor ambient temperatures have a great influence on the air conditioning capability of the fresh air conditioner, the fitting formula between the outdoor ambient temperature and the air conditioning time is used. Or the corresponding relationship determines the air conditioning time, further ensuring the accuracy of the air conditioning time, and avoiding excessive waste of energy.

本发明的实施例三在实施例二的基础上，去掉了基于室外环境温度，确定空气调节时间的步骤，而是直接指定一个固定的空气调节时间。因为，只要适当调整压缩机频率、送风机转速等新风空调的参数，就能够保证每次都能够在固定的空气调节时间内完成调节。但相应地，其相对于实施例二的空气调节时间会有一定的误差，因此最终确定的提前开启时刻也会有一定的误差，但此处误差是可以接受范围内的。The third embodiment of the present invention, on the basis of the second embodiment, removes the step of determining the air conditioning time based on the outdoor ambient temperature, but directly specifies a fixed air conditioning time. Because, as long as the parameters of the fresh air air conditioner such as the compressor frequency and the blower speed are properly adjusted, it can be ensured that the adjustment can be completed within a fixed air conditioning time every time. However, correspondingly, there will be a certain error relative to the air conditioning time of the second embodiment, so there will also be a certain error in the final determined advance opening time, but the error here is within an acceptable range.
具体实施例参见图4，其中，图4为为本发明的实施例三的新风空调的控制方法的流程图。For a specific embodiment, refer to FIG. 4 , wherein FIG. 4 is a flowchart of a control method for a fresh air conditioner according to Embodiment 3 of the present invention.
如图4所示，在一种可能的实施方式中，新风空调的控制方法还包括：As shown in Figure 4, in a possible implementation, the control method of the fresh air conditioner further includes:
S120、获取新风空调的预设开机时刻；S120. Obtain the preset startup time of the fresh air conditioner;
S121、基于时间修正参数，修正预设开机时刻；S121. Based on the time correction parameter, correct the preset start-up time;
S122、基于预设的空气调节时间和修正后的预设开机时刻，确定提前开启时刻；S122, determining the early start time based on the preset air conditioning time and the corrected preset start time;
S123、在到达提前开启时刻时，开启S100步骤。S123, when the advance start time is reached, start step S100.
实施例四Embodiment 4
本发明的实施例四中，在基于实施例二的基础上，去掉了基于时间修正参数，修正预设开机时刻的步骤。但相应的，由于实施例四缺少了对于预设开机时刻的修正步骤，因此其会相对于实施例二有一定的误差，但此处误差是可以接受范围内的。In the fourth embodiment of the present invention, on the basis of the second embodiment, the step of correcting the preset power-on time based on the time correction parameter is removed. However, correspondingly, since the fourth embodiment lacks the correction step for the preset power-on time, there will be a certain error compared to the second embodiment, but the error here is within an acceptable range.
具体实施例参见图5，其中，图5为本发明的实施例四的新风空调的控制方法的流程图。For a specific embodiment, refer to FIG. 5 , wherein FIG. 5 is a flowchart of a control method for a fresh air conditioner according to Embodiment 4 of the present invention.
如图5所示，在一种可能的实施方式中，新风空调的控制方法还包括：As shown in Figure 5, in a possible implementation, the control method of the fresh air conditioner further includes:
S130、获取新风空调的预设开机时刻和室外环境温度；S130. Obtain the preset startup time and outdoor ambient temperature of the fresh air conditioner;
S131、基于室外环境温度，确定空气调节时间；S131, determining the air conditioning time based on the outdoor ambient temperature;
S132、基于空气调节时间和预设开机时刻，确定提前开启时刻；S132, determining the early start time based on the air conditioning time and the preset start time;
S133、在到达提前开启时刻时，开启S100步骤。S133, when the advance start time is reached, start step S100.
在实施例二至实施例四里面，均是基于新风空调会提前开启，然后对提前开启时刻进行各种方式的优化，但是，如果用户在一段时间内，生活并不规律，例如经常出差，或者经常加班造成回家时间不稳定的话，那么是否开启S100步骤对室内空气进行调节，就需要进行判定了。基于上述问题，本发明的实施例五提出了一种判断方法，来确定是否开启S100步骤。In Embodiments 2 to 4, it is based on the fact that the fresh air air conditioner will be turned on in advance, and then various methods are carried out to optimize the time of early activation. However, if the user lives irregularly within a period of time, such as frequent business trips, or If the time to go home is unstable due to frequent overtime work, then it needs to be judged whether the step S100 is turned on to adjust the indoor air. Based on the above problem, the fifth embodiment of the present invention proposes a judgment method to determine whether to enable step S100.
实施例五Embodiment 5
为了解决当用户生活不规律时，新风空调不能够自主判断是否对室内空气进行调节的问题，本发明在S100步骤之前还增加了对于是否开启新风空调进行预测的步骤。In order to solve the problem that the fresh air conditioner cannot independently determine whether to adjust the indoor air when the user's life is irregular, the present invention also adds a step of predicting whether to turn on the fresh air conditioner before step S100.
具体实施例参见图6和图7，其中，图6为本发明的实施例五的新风空调的控制方法的流程图，图7为本发明的实施例五的打分系统的示意图。6 and 7 for specific embodiments, wherein FIG. 6 is a flowchart of a control method for a fresh air conditioner according to Embodiment 5 of the present invention, and FIG. 7 is a schematic diagram of a scoring system according to Embodiment 5 of the present invention.
如图6所示，在一种较佳的实施方式中，新风空调的控制方法还包括：As shown in Figure 6, in a preferred embodiment, the control method of the fresh air conditioner further includes:
S141、当到达预测时间点时，基于预先建立的打分系统，计算所述新风空调在今日的提前开启时刻开启新风空调的概率得分。S141. When the predicted time point is reached, based on a pre-established scoring system, calculate the probability score of the fresh air air conditioner being turned on at today's early start time.
其中，打分系统用于表征新风空调的历史运行信息和历史预测信息与新风空调在下一提前开启时刻开启新风空调的概率得分之间的对应关系。提前开启时刻与上述实施例二至实施例四中的含义相同，预测时间点为提前开启时刻之前的某一时间点，提前开启时刻为19:00，而预测时间点可以为19:00之前的1小时，即18:00。The scoring system is used to characterize the correspondence between the historical operation information and historical prediction information of the fresh air air conditioner and the probability score of the fresh air air conditioner turning on the fresh air air conditioner at the next early start time. The advance opening time is the same as the meaning in the above-mentioned Embodiments 2 to 4, the predicted time point is a certain time point before the advance opening time, the advance opening time is 19:00, and the predicted time point can be before 19:00. 1 hour, or 18:00.
云端服务器调用预先建立的打分系统，计算在19:00时新风空调提前开启的概率得分，也即新风空调在19:00时提前开启的概率。其中，打分系统用于表征新风空调的历史运行信息和历史预测信息与新风空调在下一提前开启时刻开启新风空调的概率得分之间的对应关系，也就是说，将19:00输入打分系统后，打分系统会基于新风空调的历史运行信息和历史预测信息计算出在该时间点提前开启新风空调的概率。The cloud server invokes the pre-established scoring system to calculate the probability score of the fresh air air conditioner being turned on in advance at 19:00, that is, the probability of the fresh air air conditioner being turned on in advance at 19:00. Among them, the scoring system is used to characterize the correspondence between the historical operation information and historical prediction information of the fresh air air conditioner and the probability score of the fresh air air conditioner turning on the fresh air air conditioner at the next early start time. That is to say, after 19:00 is entered into the scoring system, The scoring system will calculate the probability of turning on the fresh air conditioner in advance at this time point based on the historical operation information and historical forecast information of the fresh air air conditioner.
在一种较佳的实施方式中，步骤S141可以进一步包括：将下一提前开启时刻输入预先训练的新风空调开启概率模型，得到新风空调在下一提前开启时刻开启新风空调的历史开启概率；基于设定天数内在下一提前开启时刻开启新风空调的天数，得到近期开启概率；基于历史预测信息，得到下一提前开启时刻的历史预测准确率；基于历史开启概率、近期开启概率和历史预测准确率，计算新风空调在下一提前开启时刻开启新风空调的概率得分；其中，新风空调开启概率模型用于表征历史运行信息与历史开启概率之间的对应关系。具体地，如图7所示，在本实施方式中，在将提前开启时刻输入打分系统后，打分系统计算的分数来源于三部分，第一部分为基于训练好的新风空调开启概率模型计算出的历史开启频率；第二部分为基于该提前开启时刻在设定天数内开启的次数得到的近期开启概率；第三部分为基于历史预测信息得到的该提前开启时刻的历史预测准确率；概率得分可以为历史开启概率、近期开启概率和历史预测准确率的加权值，其中三部分在打分系统中所占的权值分别可以为70分、15分和15分。In a preferred embodiment, step S141 may further include: inputting the next early start time into a pre-trained fresh air conditioner on probability model to obtain the historical start probability of the fresh air air conditioner turning on the fresh air air conditioner at the next early start time; The number of days in which the fresh air conditioner is turned on at the next early turn-on time within a fixed number of days, and the recent turn-on probability is obtained; based on historical forecast information, the historical prediction accuracy rate of the next early turn-on time is obtained; based on the historical turn-on probability, recent turn-on probability and historical prediction accuracy, Calculate the probability score of the fresh air air conditioner turning on the fresh air air conditioner at the next early start time; wherein, the fresh air air conditioner opening probability model is used to represent the corresponding relationship between the historical operation information and the historical opening probability. Specifically, as shown in FIG. 7 , in this embodiment, after the early start time is input into the scoring system, the score calculated by the scoring system comes from three parts, and the first part is calculated based on the trained fresh air conditioner opening probability model The historical opening frequency; the second part is the recent opening probability based on the number of times the early opening time is opened within the set number of days; the third part is the historical prediction accuracy rate of the early opening time obtained based on the historical prediction information; the probability score can be It is the weighted value of the historical opening probability, the recent opening probability and the historical prediction accuracy. The weights of the three parts in the scoring system can be 70 points, 15 points and 15 points respectively.
其中，第一部分中，新风空调开启概率模型的建立过程具体可以为：以历史提前开启新风空调时刻、该开启新风空调时刻对应的开机次数和新风空调的总运行天数为特征数据建立模型，得到历史提前开启新风空调时刻与历史开启概率的对应关系，再将提前开启时刻输入该模型中，便可输出该提前开启时刻对应的历史开启概率。其中，第二部分中，设定天数可以为最近7天，最近7天中开启天数每增加1天的近期开启概率增加20％，当开启5天以上时，近期开启概率为100％。其中，第三部分中，历史预测信息可以为在该提前开启时刻的历史预测中，预测正确的数量与预测总数量的比值。Among them, in the first part, the establishment process of the probability model of the fresh air air conditioner can specifically be: building a model based on the historical time when the fresh air air conditioner is turned on in advance, the number of times of starting the fresh air air conditioner corresponding to the time when the fresh air air conditioner is turned on, and the total operating days of the fresh air air conditioner as the characteristic data to obtain the history The corresponding relationship between the time of turning on the fresh air conditioner in advance and the historical turning-on probability, and then inputting the early turning-on time into the model, the historical turning-on probability corresponding to the early turning-on time can be output. Among them, in the second part, the set number of days can be the last 7 days, and the recent opening probability increases by 20% for each additional day in the last 7 days. When the opening day is more than 5 days, the recent opening probability is 100%. Wherein, in the third part, the historical prediction information may be the ratio of the number of correct predictions to the total number of predictions in the historical prediction at the early start time.
举例而言，将下一提前开启时刻为19:00输入打分系统后，开启新风空调概率模型计算出在该开机时刻的历史开启概率为80％；近7 天内开启天数为4天，则近期开启概率为80％；在19:00提前开启时刻的预测正确数量为7次，总数量为10次，即预测准确率为70％；由此将三个概率分别与其权值相乘后求和，得出概率得分为P＝80％×70+80％× 15+70％×15＝78.5分。For example, after entering the next early turn-on time at 19:00 into the scoring system, the probability model of turning on the fresh air conditioner calculates that the historical turn-on probability at this turn-on time is 80%; if the number of days turned on in the past 7 days is 4 days, it will be turned on recently. The probability is 80%; the number of correct predictions at the time of early opening at 19:00 is 7 times, and the total number is 10 times, that is, the prediction accuracy rate is 70%; thus, the three probabilities are multiplied by their weights and summed, The probability score is obtained as P=80%×70+80%×15+70%×15=78.5 points.
S142、当概率得分大于设定阈值，且在到达提前开启时刻时，进入S100步骤。S142 , when the probability score is greater than the set threshold, and when the advance opening time is reached, go to step S100 .
例如，在满分100分的前提下，打分系统在18:00时计算出在19:00时提前开启新风空调的概率得分为80分(即提前开启新风空调的概率为80％)，证明用户很大可能在19:00后使用新风空调，此时当到达提前开启时刻，云端服务器下发开启S100步骤的指令，以便新风空调在19:00开机并开始调节室内的二氧化碳浓度和温度。再如，在打分系统计算出19:00提前开启新风空调的概率得分为50分，证明用户很大可能在19:00以后不会使用空调，此时云端服务器控制新风空调不开启S100 步骤。For example, under the premise of a full score of 100 points, the scoring system calculates at 18:00 that the probability of turning on the fresh air conditioner in advance at 19:00 is 80 points (that is, the probability of turning on the fresh air conditioner in advance is 80%), which proves that the user is very It is very likely that the fresh air conditioner will be used after 19:00. At this time, when it is time to turn on in advance, the cloud server will issue an instruction to start step S100, so that the fresh air air conditioner will be turned on at 19:00 and begin to adjust the indoor carbon dioxide concentration and temperature. For another example, the scoring system calculates that the probability of turning on the fresh air conditioner in advance at 19:00 is 50 points, which proves that the user is likely not to use the air conditioner after 19:00. At this time, the cloud server controls the fresh air conditioner not to turn on the S100 step.
进一步地，在一种较佳的实施方式中，预测时间点可以基于如下方法确定：Further, in a preferred embodiment, the predicted time point can be determined based on the following method:
基于新风空调的历史运行信息，选择性地确定预测时间点。具体地，基于新风空调的历史运行信息，判断新风空调的活跃度；在新风空调的活跃度为高时，统计设定天数内新风空调在多个运行时段的运行次数；从多个运行时段内选取若干个运行次数大于设定次数的运行时段；分别计算每个被选取的运行时段内所有新风空调提前开启时的开启时刻的平均值作为该运行时段的提前开启时刻；计算每个提前开启时刻与预设时间段的差值作为该提前开启时刻的预测时间点。举例而言，新风空调的活跃度可以定义为在过去几天(如过去3天)有无开机行为，当过去几天内用户有开机记录时，则新风空调的活跃度为高，否则，活跃度为低。在活跃度为低时，证明用户使用空调的次数较少，开启空调概率较低，此时不对新风空调是否开启进行预测。在新风空调的活跃度为高时，证明用户使用新风空调较为频繁，其使用新风空调的习惯和规律更容易分析，此时统计设定天数内(如最近7天内)新风空调在多个运行时段的运行次数，如对所有开机的时刻按1小时为一个运行时段聚合计数，然后从多个运行时段中挑选出若干个7天内开机次数大于4次的时段，然后分别计算每个时段内的所有开机时刻的平均值，作为该运行时段的提前开启时刻，最后将每个提前开启时刻减去1小时候的时间点作为预测时间点，如某一提前开启时刻为19:00，那么18:00即为该提前开启时刻的预测时间点。Based on the historical operation information of the fresh air conditioner, the predicted time point is selectively determined. Specifically, based on the historical operation information of the fresh air air conditioner, determine the activity of the fresh air air conditioner; when the activity degree of the fresh air air conditioner is high, count the number of operations of the fresh air air conditioner in multiple operation periods within the set number of days; Select a number of operation periods with a number of operations greater than the set number of times; calculate the average value of the start-up time of all fresh air conditioners in each selected operation period when they are turned on in advance as the early start time of the operation period; calculate each early start time The difference from the preset time period is used as the predicted time point of the early turn-on time. For example, the activity of the fresh air conditioner can be defined as whether it has been turned on in the past few days (such as the past 3 days). degree is low. When the activity is low, it proves that the user uses the air conditioner less frequently, and the probability of turning on the air conditioner is low. At this time, no prediction is made on whether the fresh air conditioner is turned on. When the activity of the fresh air conditioner is high, it proves that the user uses the fresh air air conditioner more frequently, and the habit and law of using the fresh air air conditioner are easier to analyze. At this time, the statistics of the fresh air air conditioner within the set number of days (such as the last 7 days) are in multiple operating periods. For example, aggregate and count all the booting times as a running period of 1 hour, and then select a number of periods with more than 4 booting times within 7 days from multiple running periods, and then calculate all the times in each period. The average value of the start-up time is used as the early start time of the operating period. Finally, the time point of each early start time minus 1 hour is used as the predicted time point. If a certain early start time is 19:00, then 18:00 is It is the predicted time point of the early start time.
通过上述控制方式，本发明的控制方法能够提高新风空调的智能化程度和用户体验。具体而言，通过在到达预测时间点时，基于打分系统计算新风空调在下一提前开启时刻开启新风空调的概率得分，本控制方法能够基于用户使用新风空调的历史信息，合理预测用户在下一提前开启时刻开启空调的概率，从而在开启空调的概率较高时，在提前开启时候到来后，控制S100步骤开启，以控制室内二氧化碳浓度和温度。并且，由于该预测过程全部自动完成，因此本控制方法能够提高新风空调的智能化程度，提升用户体验。Through the above control method, the control method of the present invention can improve the intelligence level and user experience of the fresh air air conditioner. Specifically, by calculating the probability score of the fresh air air conditioner at the next early start time of the fresh air air conditioner when the predicted time point is reached, the control method can reasonably predict that the user will turn on the fresh air air conditioner in advance based on the historical information of the user's use of the fresh air air conditioner. The probability of turning on the air conditioner at all times, so that when the probability of turning on the air conditioner is high, after the early turn-on time arrives, the step S100 is controlled to turn on, so as to control the indoor carbon dioxide concentration and temperature. Moreover, since the prediction process is all completed automatically, the control method can improve the intelligence of the fresh air air conditioner and improve the user experience.
至此，已经结合附图所示的优选实施方式描述了本发明的技术方案，但是，本领域技术人员容易理解的是，本发明的保护范围显然不局限于这些具体实施方式。在不偏离本发明的原理的前提下，本领域技术人员可以对相关技术特征作出等同的更改或替换，这些更改或替换之后的技术方案都将落入本发明的保护范围之内。So far, the technical solutions of the present invention have been described with reference to the preferred embodiments shown in the accompanying drawings, however, those skilled in the art can easily understand that the protection scope of the present invention is obviously not limited to these specific embodiments.
