以下结合附图对本发明的具体实施方式进行详细说明。应当理解的是，此处所描述的具体实施方式仅用于说明和解释本发明，并不用于限制本发明。Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.
如图1所示，作为本发明的一个方面，提供一种双制冷车载冰箱的控制方法，其中，所述双制冷车载冰箱包括压缩机制冷系统和半导体制冷系统，所述控制方法包括：As shown in Figure 1, as an aspect of the present invention, a control method for a dual-refrigeration vehicle-mounted refrigerator is provided, wherein the dual-refrigeration vehicle-mounted refrigerator includes a compressor refrigeration system and a semiconductor refrigeration system, and the control method includes:
S200、当接收到双制冷车载冰箱工作指令时，判断包括所述双制冷车载冰箱所处的环境条件是否满足预定环境条件。S200. When receiving a working instruction of the dual-refrigeration vehicle-mounted refrigerator, judge including whether the environmental conditions of the dual-refrigeration vehicle-mounted refrigerator meet predetermined environmental conditions.
其中，在一种实施方式中，所述环境条件包括所述双制冷车载冰箱所处的温度，所述预定环境条件包括预定温度，则满足所述预定条件包括：所述双制冷车载冰箱所处的温度低于所述预定温度。Wherein, in one embodiment, the environmental condition includes the temperature of the dual-refrigeration vehicle-mounted refrigerator, and the predetermined environmental condition includes a predetermined temperature, then satisfying the predetermined condition includes: the temperature of the dual-refrigeration vehicle-mounted refrigerator The temperature is lower than the predetermined temperature.
在另一种实施方式中，所述环境条件包括承载所述双制冷车载冰箱的车辆所处的坡度；所述预定环境条件包括预定坡度，则满足所述预定条件包括：承载所述双制冷车载冰箱的车辆所处的坡度小于所述预定坡度。In another embodiment, the environmental conditions include the slope of the vehicle carrying the dual-refrigeration vehicle-mounted refrigerator; the predetermined environmental conditions include a predetermined slope, and satisfying the predetermined condition includes: carrying the dual-refrigeration vehicle-mounted refrigerator The slope on which the vehicle of the refrigerator is located is smaller than the predetermined slope.
优选的，在又一种实施方式中，所述环境条件包括所述双制冷车载冰箱所处的温度以及承载所述双制冷车载冰箱的车辆所处的坡度；所述预定环境条件包括预定温度和预定坡度，满足所述预定条件包括：所述双制冷车载冰箱所处的温度低于所述预定温度，以及承载所述双制冷车载冰箱的车辆所处的坡度小于所述预定坡度。Preferably, in yet another embodiment, the environmental conditions include the temperature of the dual-refrigeration vehicle-mounted refrigerator and the slope of the vehicle carrying the dual-refrigeration vehicle-mounted refrigerator; the predetermined environmental conditions include a predetermined temperature and The predetermined slope, meeting the predetermined condition includes: the temperature of the dual-refrigeration vehicle-mounted refrigerator is lower than the predetermined temperature, and the slope of the vehicle carrying the dual-refrigeration vehicle-mounted refrigerator is lower than the predetermined slope.
S300、当所述双制冷车载冰箱所处的环境条件满足所述预定环境条件时，控制所述压缩机制冷系统开启；S300. When the environmental condition of the dual-refrigeration vehicle-mounted refrigerator satisfies the predetermined environmental condition, control the compressor refrigeration system to be turned on;

When the environmental condition of the dual-refrigeration vehicle-mounted refrigerator does not meet the predetermined environmental condition, control the compressor refrigeration system to be turned off, and simultaneously control the semiconductor refrigeration system to be turned on.
在车辆的行驶过程中，车辆内部的温度、以及车辆本身的所处的坡度会发生变化。对于制冷效果较好的压缩机制冷系统而言，当车辆内部温度较高(超过预定温度)时，压缩机制冷系统的制冷效果将下降。并且，当车辆所处的坡度较大时，润滑油将流入压缩机制冷系统，并损坏压缩机制冷系统。During the running of the vehicle, the temperature inside the vehicle and the slope of the vehicle itself will change. For the compressor refrigeration system with better refrigeration effect, when the internal temperature of the vehicle is high (over a predetermined temperature), the refrigeration effect of the compressor refrigeration system will decrease. Moreover, when the vehicle is on a steep slope, the lubricating oil will flow into the compressor refrigeration system and damage the compressor refrigeration system.
在本发明所提供的控制方法中，当所述双制冷车载冰箱所处的环境条件满足所述预定环境条件时，所述压缩机制冷系统处于较优的工作状态，可以达到较好的制冷效果。因此，当所述双制冷车载冰箱所处的环境条件满足所述预定环境条件时，开启所述压缩机制冷系统进行制冷。In the control method provided by the present invention, when the environmental conditions of the dual-refrigeration vehicle-mounted refrigerator meet the predetermined environmental conditions, the compressor refrigeration system is in a better working state, and a better cooling effect can be achieved . Therefore, when the environmental condition of the dual-refrigeration vehicle-mounted refrigerator satisfies the predetermined environmental condition, the compressor refrigeration system is turned on for refrigeration.
当安装所述双制冷车载冰箱的车辆内部温度超过预定温度时，因此，可以控制压缩机制冷系统关闭，利用半导体制冷系统进行制冷，从而可以确保当车内温度较高时，所述双制冷车载冰箱仍然具有较好的制冷效果。When the internal temperature of the vehicle on which the dual-refrigeration vehicle-mounted refrigerator is installed exceeds a predetermined temperature, the compressor refrigeration system can be controlled to shut down, and the semiconductor refrigeration system can be used for refrigeration, thereby ensuring that when the temperature inside the vehicle is high, the dual-refrigeration vehicle-mounted refrigerator can The refrigerator still has a good cooling effect.
当承载所述双制冷车载冰箱的测车辆所处的坡度超过所述预定坡度时，控制所述压缩机制冷系统停止工作，从而可以防止润滑油流入压缩机制冷系统，进而可以避免压缩机制冷系统收到损坏。When the slope of the test vehicle carrying the dual-refrigeration vehicle-mounted refrigerator exceeds the predetermined slope, the compressor refrigeration system is controlled to stop working, thereby preventing lubricating oil from flowing into the compressor refrigeration system, thereby preventing the compressor refrigeration system from received damaged.
因此，本发明所提供的控制方法控制所述双制冷车载冰箱进行制冷，使得所述双制冷车载冰箱能够在车辆行驶的过程中实现较好的制冷效果，并且，可以确保双制冷车载冰箱不会发生损坏。Therefore, the control method provided by the present invention controls the dual-refrigeration vehicle-mounted refrigerator to perform cooling, so that the dual-refrigeration vehicle-mounted refrigerator can achieve a better cooling effect during the driving process of the vehicle, and can ensure that the dual-refrigeration vehicle-mounted refrigerator will not Damage occurred.
需要解释的是，如果在执行步骤200时是基于第三种实施方式(即同时考虑所述双制冷车载冰箱所处的环境温度以及承载所述双制冷车载冰箱的车辆所处的坡度的实施方式)，则在步骤S400中所述的“所述双制冷车载冰箱所处的环境条件未满足所述预定环境条件”包括如下三种情况：一、所述双制冷车载冰箱所处的环境温度不低于所述预定温度、且承载所述双制冷车载冰箱的车辆所处的坡度不小于所述预定坡度；二、所述双制冷车载冰箱所处的环境温度低于所述预定温度、且承载所述双制冷车载冰箱的车辆所处的坡度不小于所述预定坡度；三、所述双制冷车载冰箱所处的环境温度不低于所述预定温度、且承载所述双制冷车载冰箱的车辆所处的坡度小于所述预定坡度。It needs to be explained that if the execution of step 200 is based on the third embodiment (i.e., the embodiment that simultaneously considers the ambient temperature of the dual-refrigeration vehicle-mounted refrigerator and the slope of the vehicle carrying the dual-refrigeration vehicle-mounted refrigerator ), then the "environmental conditions of the dual-refrigeration vehicle-mounted refrigerator that do not meet the predetermined environmental conditions" described in step S400 include the following three situations: 1. The ambient temperature of the dual-refrigeration vehicle-mounted refrigerator is not The slope of the vehicle carrying the dual-refrigeration car refrigerator is not less than the predetermined slope; 2. The ambient temperature of the dual-refrigeration car refrigerator is lower than the predetermined temperature and the vehicle is carrying The slope of the vehicle with the dual-refrigeration vehicle-mounted refrigerator is not less than the predetermined slope; 3. The ambient temperature of the dual-refrigeration vehicle-mounted refrigerator is not lower than the predetermined temperature, and the vehicle carrying the dual-refrigeration vehicle-mounted refrigerator The slope is smaller than the predetermined slope.
以及，在步骤S200中，可以先判断所述双制冷车载冰箱所处的温度是否低于所述预定温度、再判断所述车辆所处的坡度是否低于所述预定坡度；也可以先判断所述车辆所处的坡度是否低于所述预定坡度、再判断所述双制冷车载冰箱所处的温度是否低于所述预定温度。And, in step S200, it may first be judged whether the temperature of the dual-refrigeration vehicle-mounted refrigerator is lower than the predetermined temperature, and then whether the slope of the vehicle is lower than the predetermined slope; Whether the slope where the vehicle is located is lower than the predetermined slope, and then judge whether the temperature of the dual-refrigeration vehicle-mounted refrigerator is lower than the predetermined temperature.
在一种可选的实施方式中，当所述双制冷车载冰箱所处的环境条件满足所述预定环境条件时，控制所述压缩机制冷系统开启的同时，还可以控制所述半导体制冷系统开启。In an optional implementation manner, when the environmental condition of the dual-refrigeration car refrigerator satisfies the predetermined environmental condition, when the compressor refrigeration system is controlled to be turned on, the semiconductor refrigeration system may also be controlled to be turned on. .
不过，由于当所述双制冷车载冰箱所处的环境条件满足所述预定环境条件时，采用压缩机制冷系统就可以达到较好的制冷效果，能够满足制冷需求，因此，为了降低双制冷车载冰箱的能耗，在另一种可选的实施方式中，当所述双制冷车载冰箱所处的环境条件满足所述预定环境条件时，控制所述压缩机制冷系统开启的同时，控制所述半导体制冷系统关闭。由此，可以同时满足制冷需求和低能耗需求。However, when the environmental conditions of the dual-refrigeration vehicle-mounted refrigerator meet the predetermined environmental conditions, the use of the compressor refrigeration system can achieve a better cooling effect and meet the cooling demand. Therefore, in order to reduce the In another optional implementation manner, when the environmental condition of the dual-refrigeration car refrigerator satisfies the predetermined environmental condition, the compressor refrigeration system is controlled to be turned on, and the semiconductor The refrigeration system is off. As a result, cooling requirements and low energy consumption requirements can be met at the same time.
在本发明中，对所述预定温度的具体值并没有特殊的要求，所述预定温度由所述压缩机制冷系统所采用的制冷剂的特性所决定。作为一种具体实施方式，所述制冷剂可以为绿色环保制冷剂R134a(即，1，1，1，2-四氟乙烷)或者制冷剂R600a(即，异丁烷)，在这种情况中，所述预定温度可以在50℃至60℃之间。进一步优选地，所述预定温度可以为55℃。In the present invention, there is no special requirement on the specific value of the predetermined temperature, and the predetermined temperature is determined by the characteristics of the refrigerant used in the compressor refrigeration system. As a specific implementation, the refrigerant can be green environmental protection refrigerant R134a (that is, 1,1,1,2-tetrafluoroethane) or refrigerant R600a (that is, isobutane), in this case , the predetermined temperature may be between 50°C and 60°C. Further preferably, the predetermined temperature may be 55°C.
可选的，所述预定坡度可以由整车制造厂根据其选用压缩机制冷系统的特点来设置。Optionally, the predetermined slope can be set by the vehicle manufacturer according to the characteristics of the compressor refrigeration system selected.
为了便于实现所述车载冰箱控制的自动化，可选的，所述控制方法还包括：In order to facilitate the automation of the control of the vehicle-mounted refrigerator, optionally, the control method further includes:

容易理解的是，在整个控制方法中，在执行步骤S200之前执行步骤S100。It is easy to understand that, in the whole control method, step S100 is executed before step S200 is executed.
为了使得所述控制方法适用于多种不同型号、不同结构的双制冷车载冰箱，优选地，所述控制方法还可以包括在步骤S100之前进行的：In order to make the control method applicable to multiple types of dual-refrigeration car refrigerators with different structures, preferably, the control method may also include performing before step S100:

Moreover, the control module 232 is also configured to control the compressor refrigeration system 210 to be turned off and the semiconductor refrigeration system 220 to be turned on when the environmental judgment module 231 detects that the environmental condition does not meet the predetermined environmental condition (ie, execute step S400).
其中，环境判定模块231在执行步骤S200时，可以通过以下几种方式：Wherein, when the environment judging module 231 executes step S200, the following methods can be adopted:
在一种实施方式中，所述环境条件包括所述双制冷车载冰箱所处的温度，所述预定环境条件包括预定温度，则满足所述预定条件包括：所述双制冷车载冰箱所处的温度低于所述预定温度。In one embodiment, the environmental conditions include the temperature of the dual-refrigeration vehicle-mounted refrigerator, and the predetermined environmental conditions include a predetermined temperature, then satisfying the predetermined condition includes: the temperature of the dual-refrigeration vehicle-mounted refrigerator below the predetermined temperature.
在另一种实施方式中，所述环境条件包括承载所述双制冷车载冰箱的车辆所处的坡度；所述预定环境条件包括预定坡度，则满足所述预定条件包括：承载所述双制冷车载冰箱的车辆所处的坡度小于所述预定坡度。In another embodiment, the environmental conditions include the slope of the vehicle carrying the dual-refrigeration vehicle-mounted refrigerator; the predetermined environmental conditions include a predetermined slope, and satisfying the predetermined condition includes: carrying the dual-refrigeration vehicle-mounted refrigerator The slope on which the vehicle of the refrigerator is located is smaller than the predetermined slope.
优选的，在又一种实施方式中，所述环境条件包括所述双制冷车载冰箱所处的温度以及承载所述双制冷车载冰箱的车辆所处的坡度；所述预定环境条件包括预定温度和预定坡度，满足所述预定条件包括：所述双制冷车载冰箱所处的温度低于所述预定温度，以及承载所述双制冷车载冰箱的车辆所处的坡度小于所述预定坡度。Preferably, in yet another embodiment, the environmental conditions include the temperature of the dual-refrigeration vehicle-mounted refrigerator and the slope of the vehicle carrying the dual-refrigeration vehicle-mounted refrigerator; the predetermined environmental conditions include a predetermined temperature and The predetermined slope, meeting the predetermined condition includes: the temperature of the dual-refrigeration vehicle-mounted refrigerator is lower than the predetermined temperature, and the slope of the vehicle carrying the dual-refrigeration vehicle-mounted refrigerator is lower than the predetermined slope.
需要解释的是，如果在执行步骤200时是基于第三种实施方式(即同时考虑所述双制冷车载冰箱所处的环境温度以及承载所述双制冷车载冰箱的车辆所处的坡度的实施方式)，则“环境判断模块231检测到环境条件未满足所述预定环境条件”包括如下三种情况：一、环境判断模块231检测到的环境温度不低于所述预定温度、且环境判断模块231检测到的坡度不小于所述预定坡度；二、环境判断模块231检测到的环境温度低于所述预定温度、且环境判断模块231检测到的坡度不小于所述预定坡度；三、环境判断模块231检测到的环境温度不低于所述预定温度、且环境判断模块231检测到的坡度小于所述预定坡度。It needs to be explained that if the execution of step 200 is based on the third embodiment (i.e., the embodiment that simultaneously considers the ambient temperature of the dual-refrigeration vehicle-mounted refrigerator and the slope of the vehicle carrying the dual-refrigeration vehicle-mounted refrigerator ), then "the environmental judgment module 231 detects that the environmental condition does not meet the predetermined environmental condition" includes the following three situations: 1. The ambient temperature detected by the environmental judgment module 231 is not lower than the predetermined temperature, and the environmental judgment module 231 The detected slope is not less than the predetermined slope; 2. The ambient temperature detected by the environment judgment module 231 is lower than the predetermined temperature, and the slope detected by the environment judgment module 231 is not less than the predetermined slope; 3. The environment judgment module The ambient temperature detected by 231 is not lower than the predetermined temperature, and the slope detected by the environment judging module 231 is smaller than the predetermined slope.
可选的，控制模块232可以在所述双制冷车载冰箱所处的环境条件满足所述预定环境条件时，控制所述压缩机制冷系统210开启的同时还控制半导体制冷系统220关闭。由此，可以同时满足制冷需求和低能耗需求。Optionally, the control module 232 may control the compressor refrigeration system 210 to be turned on and the semiconductor refrigeration system 220 to be turned off when the environmental condition of the dual-refrigeration car refrigerator satisfies the predetermined environmental condition. As a result, cooling requirements and low energy consumption requirements can be met at the same time.
作为本发明的具体实施方式，环境判定模块231可以包括温度传感器231a和角度传感器231b。温度传感器231a用于检测所述双制冷车载冰箱所处的环境温度，角度传感器231b用于检测所述双制冷车载冰箱所处的车辆的坡度。As a specific embodiment of the present invention, the environment determination module 231 may include a temperature sensor 231a and an angle sensor 231b. The temperature sensor 231a is used to detect the ambient temperature where the dual-refrigeration vehicle-mounted refrigerator is located, and the angle sensor 231b is used to detect the gradient of the vehicle where the dual-refrigeration vehicle-mounted refrigerator is located.
控制模块232用于将温度传感器231a检测到的环境温度与所述预设温度进行比较，且控制模块232用于将角度传感器231b检测到的坡度与所述预设坡度进行比较。当然，如果环境判定模块231在执行步骤S200时是基于前两种实施方式(即只考虑所述双制冷车载冰箱所处的环境温度，或者只考虑所述双制冷车载冰箱所处的车辆的坡度的方式)，则环境判定模块231中可以只包括温度传感器231a，或者只包括角度传感器231b。The control module 232 is used to compare the ambient temperature detected by the temperature sensor 231a with the preset temperature, and the control module 232 is used to compare the slope detected by the angle sensor 231b with the preset slope. Of course, if the environment judgment module 231 is based on the first two implementations when executing step S200 (that is, only considering the ambient temperature of the dual-refrigeration vehicle-mounted refrigerator, or only considering the gradient of the vehicle where the dual-refrigeration vehicle-mounted refrigerator is located mode), the environment determination module 231 may only include the temperature sensor 231a, or only include the angle sensor 231b.
如上文中所述，在本发明中，对所述预定温度的具体值并没有特殊的要求，所述预定温度由所述压缩机制冷系统所采用的制冷剂的特性所决定。作为一种具体实施方式，所述制冷剂可以为绿色环保制冷剂R134a(即，1，1，1，2-四氟乙烷)或者制冷剂R600a(即，异丁烷)，在这种情况中，所述预定温度在50℃至60℃之间。进一步优选地，所述预定温度可以为55℃。As mentioned above, in the present invention, there is no special requirement on the specific value of the predetermined temperature, and the predetermined temperature is determined by the characteristics of the refrigerant used in the compressor refrigeration system. As a specific implementation, the refrigerant can be green environmental protection refrigerant R134a (that is, 1,1,1,2-tetrafluoroethane) or refrigerant R600a (that is, isobutane), in this case , the predetermined temperature is between 50°C and 60°C. Further preferably, the predetermined temperature may be 55°C.
可选的，所述预定坡度由整车制造厂根据其选用压缩机制冷系统的特点来设置。Optionally, the predetermined slope is set by the vehicle manufacturer according to the characteristics of the compressor refrigeration system selected.
为了便于执行步骤S100，优选地，控制模块232还用于判断接收到的工作指令是否为所述双制冷车载冰箱工作指令，当所述控制模块接收到的工作指令不是所述双制冷车载冰箱工作指令时，控制模块232还用于控制环境判定模块231休眠，并控制压缩机制冷系统210和半导体制冷系统220均关闭。In order to facilitate the execution of step S100, preferably, the control module 232 is also used to determine whether the received work order is the work order of the dual-refrigeration car refrigerator, when the work order received by the control module is not the work order of the dual-refrigeration car refrigerator When commanded, the control module 232 is also used to control the environment determination module 231 to sleep, and control the compressor refrigeration system 210 and the semiconductor refrigeration system 220 to shut down.
可选的，控制器230还包括输入模块233，输入模块233用于将所述预定温度和/或所述预定坡度写入所述控制模块。Optionally, the controller 230 further includes an input module 233, and the input module 233 is used for writing the predetermined temperature and/or the predetermined slope into the control module.
在本发明中，对输入模块233的具体结构并没有特殊的要求，只要能够输入所述预定温度和/或所述预定坡度即可。例如，所述输入模块233可以为键盘输入模块，或者，输入模块233还可以为触摸屏。In the present invention, there is no special requirement on the specific structure of the input module 233, as long as the predetermined temperature and/or the predetermined slope can be input. For example, the input module 233 may be a keyboard input module, or the input module 233 may also be a touch screen.
