技术领域technical field
本实用新型涉及电气控制领域,具体而言,涉及一种启动电路及人体状态检测装置。The utility model relates to the field of electrical control, in particular to a starting circuit and a human body state detection device.
背景技术Background technique
随着技术水平的提高,自动控制设备越来越多的应用到了日常生活中。常见的自动控制设备如感应灯、人体跟踪设备等。这些自动控制设备都是利用了红外传感器来对人体进行检测,进而依据检测到的信号进行相应的操作。With the improvement of technology level, more and more automatic control devices are applied to daily life. Common automatic control equipment such as sensor lights, human body tracking equipment, etc. These automatic control devices all use infrared sensors to detect the human body, and then perform corresponding operations according to the detected signals.
从自动控制设备工作流程的角度来看,自动控制设备可以分为如下三个部分:From the perspective of automatic control equipment workflow, automatic control equipment can be divided into the following three parts:
红外检测模块,用于每隔预定的时间,对指定区域进行检测,以得到环境信号;The infrared detection module is used to detect the designated area every predetermined time to obtain environmental signals;
判断模块,用于依据环境信号判断该指定区域内是否有人体驻留或通过;The judging module is used to judge whether there is a human body staying or passing in the designated area according to the environmental signal;
反馈模块,如果判断模块的判断结果为是,则用于执行预定的动作(如报警、或播放提示音等)。The feedback module is used to execute a predetermined action (such as alarming or playing a prompt tone, etc.) if the judging result of the judging module is yes.
为了适应某些复杂的使用场景,自动控制设备也变得越来越复杂,这也直接导致自动控制设备在运行过程中的能耗大幅度增加,其中,能耗主要体现在红外检测模块的实时检测方面,如进行红外检测的传感器数量增加,或者是使用高精度的红外传感器,这导致传感器扫描一次的能耗过大。In order to adapt to some complex usage scenarios, automatic control equipment has become more and more complex, which directly leads to a substantial increase in energy consumption of automatic control equipment during operation. Among them, energy consumption is mainly reflected in the real-time monitoring of infrared detection modules. In terms of detection, such as the increase in the number of sensors for infrared detection, or the use of high-precision infrared sensors, this leads to excessive energy consumption for one scan of the sensor.
对此,技术人员通常会采用降低红外检测模块的采样时间间隔的方式,来降低设备的整体能耗。但,此种方式会导致设备无法及时的检测到环境的变化,即采用此种方式会导致自动控制设备的精度下降。In this regard, technicians usually reduce the sampling time interval of the infrared detection module to reduce the overall energy consumption of the device. However, this method will cause the equipment to fail to detect changes in the environment in time, that is, the adoption of this method will lead to a decrease in the accuracy of the automatic control device.

在安全监控和智能服务等领域,经常会使用到自动控制设备。In fields such as security monitoring and intelligent services, automatic control equipment is often used.
如在安全监控领域,会使用到人体红外跟踪装置,这种装置通常是采用了红外阵列传感器作为核心器件。具体而言,该装置主要包括分别安装在房间顶部和门上的两个红外阵列传感器,以及与这两个红外阵列传感器相连的高速处理器。工作时,每个红外阵列传感器均每隔预定的时间进行一次扫描,以采集人体所发出的红外信号,如果采集到红外信号,则将红外信号传出给高速处理器,之后,高速处理器采用预定的算法,依据红外信号计算出房间内的人数,并将人数传输给远程监控端,以实现远程监控的目的。For example, in the field of security monitoring, human body infrared tracking devices are used, which usually use infrared array sensors as core components. Specifically, the device mainly includes two infrared array sensors installed on the top of the room and on the door respectively, and a high-speed processor connected to the two infrared array sensors. When working, each infrared array sensor scans at a predetermined time to collect the infrared signal emitted by the human body. If the infrared signal is collected, the infrared signal is transmitted to the high-speed processor. After that, the high-speed processor uses The predetermined algorithm calculates the number of people in the room based on the infrared signal, and transmits the number of people to the remote monitoring terminal to achieve the purpose of remote monitoring.
又如,在智能服务领域,会使用到设置在通道内的智能灯,这种灯也是采用了指定型号的红外传感器作为核心器件。具体而言,这种智能灯包括沿通道行进方向依次设置的多个红外传感器、分别与每个红外传感器连接的高速处理器和与高速处理器连接的灯具。每隔预定的时间,每个红外传感器均同时进行一次扫描,以采集人体所发出的红外信号,如果采集到红外信号,则将红外信号传出给高速处理器,高速处理器再依据预定的算法判断是否有行人处在通道内,如果是,则控制灯具进行照明。As another example, in the field of smart services, smart lights installed in the aisles will be used, and this kind of lights also use a specified type of infrared sensor as the core device. Specifically, such an intelligent lamp includes a plurality of infrared sensors sequentially arranged along the traveling direction of the aisle, a high-speed processor connected to each infrared sensor and a lamp connected to the high-speed processor. Every predetermined time, each infrared sensor scans at the same time to collect the infrared signal emitted by the human body. If the infrared signal is collected, the infrared signal is sent to the high-speed processor, and the high-speed processor is based on the predetermined algorithm. Determine whether there are pedestrians in the passage, and if so, control the lamps for lighting.
通过上述两个例子可以看出,自动控制设备在对用户进行服务时,均需要依赖于红外传感器。自动控制设备工作时,主要的能量消耗也是红外传感器(需要定时进行扫描),并且,随着使用需求的提高,所用的红外传感器的数量越来越多,红外传感器的复杂度也越来越高,这直接导致自动控制设备的工作能耗越来越高。为了降低能耗,技术人员通常会采用降低红外传感器扫描周期的方式,但此种方式会导致自动控制设备的响应滞后(如行人进入通道一段时间后,灯具才开始照明),也就是此种方式降低了自动控制设备的工作精度。It can be seen from the above two examples that the automatic control equipment needs to rely on the infrared sensor when serving the user. When the automatic control equipment is working, the main energy consumption is also the infrared sensor (which needs to be scanned regularly), and, with the increase of the use demand, the number of infrared sensors used is increasing, and the complexity of infrared sensors is also increasing , which directly leads to higher and higher energy consumption of automatic control equipment. In order to reduce energy consumption, technicians usually use the method of reducing the scanning cycle of the infrared sensor, but this method will cause the response lag of the automatic control equipment (for example, the lamps will not start to illuminate until the pedestrian enters the passage for a period of time), that is, this method The working precision of the automatic control equipment is reduced.
针对该种情况,本申请发明人提供了一种启动电路100,以降低使用红外检测模块103的自动控制设备的工作能耗。如图1所示,该启动电路100包括顺序连接的红外热释电传感器101、工作信号生成模块102和红外检测模块103;所述红外热释电传感器101的扫描区域与所述红外检测模块103的扫描区域相适应In view of this situation, the inventor of the present application provides a start-up circuit 100 to reduce the working energy consumption of the automatic control equipment using the infrared detection module 103 . As shown in Figure 1, this start-up circuit 100 comprises infrared pyroelectric sensor 101, working signal generation module 102 and infrared detection module 103 that are connected in sequence; The scanning area is adapted to the
红外热释电传感器101,用于每隔预定的时间进行扫描,并生成相应的红外检测信号;The infrared pyroelectric sensor 101 is used to scan at predetermined intervals and generate corresponding infrared detection signals;
工作信号生成模块102,用于根据红外检测信号生成工作信号;A working signal generating module 102, configured to generate a working signal according to the infrared detection signal;
红外检测模块103,用于在接收到所述工作信号后进行扫描。The infrared detection module 103 is configured to scan after receiving the working signal.
其中,红外检测模块103指的是自动控制设备中执行人体扫描的部分,且红外检测模块103的扫描能耗高于红外热释电传感器101的扫描能耗。如,红外检测模块103可以是人体红外跟踪装置中的红外阵列传感器,也可以是大量需要协同工作的红外传感器(通常这些协同工作的传感器需要同时进行扫描,或者是依次进行扫描)的集合。其中,红外检测模块103优选为红外阵列传感器(常见的型号如AMG8832)。如图7所示,示出了红外热释电传感器101的一种具体电路结构图;如图8所示,示出了红外阵列传感器的电路结构图。Wherein, the infrared detection module 103 refers to the part that performs human body scanning in the automatic control device, and the scanning energy consumption of the infrared detection module 103 is higher than that of the infrared pyroelectric sensor 101 . For example, the infrared detection module 103 may be an infrared array sensor in a human body infrared tracking device, or a collection of a large number of infrared sensors that need to work together (usually these sensors that work together need to scan simultaneously or sequentially). Wherein, the infrared detection module 103 is preferably an infrared array sensor (a common model such as AMG8832). As shown in FIG. 7 , a specific circuit structure diagram of the infrared pyroelectric sensor 101 is shown; as shown in FIG. 8 , a circuit structure diagram of the infrared array sensor is shown.
本方案的核心点在于通过低功耗的红外热释电传感器101进行预检测,并生成相应的红外检测信号,之后工作信号生成模块102依据红外检测信号的情况来判断是否需要生成工作信号(一般情况下,当红外热释电传感器101检测到有热源移动时(如有温度变化时),就可以生成工作信号),以驱动高功耗的红外检测模块103进行工作。相较于相关技术中,红外检测模块103每隔预定的时间进行一次扫描的工作方式,采用低功耗的红外热释电传感器101来带动红外检测模块103进行工作,一定程度上降低了红外检测模块103的扫描次数,从而降低了系统的整体能耗。The core point of this solution is to perform pre-detection through the low-power infrared pyroelectric sensor 101, and generate a corresponding infrared detection signal, and then the working signal generation module 102 judges whether to generate a working signal according to the situation of the infrared detection signal (generally In some cases, when the infrared pyroelectric sensor 101 detects that there is a heat source moving (for example, when there is a temperature change), it can generate a working signal) to drive the infrared detection module 103 with high power consumption to work. Compared with the related technology, where the infrared detection module 103 scans every predetermined time, the infrared detection module 103 is driven by the low power consumption infrared pyroelectric sensor 101, which reduces the infrared detection to a certain extent. The number of scans of the module 103 reduces the overall energy consumption of the system.
为了使红外热释电传感器101能够起到预检测的作用,红外热释电传感器101的扫描区域(第一扫描区域)与所述红外检测模块103的扫描区域(第二扫描区域)应当是相适应的。此处的相适应指的是第一扫描区域与第二扫描区域重合、部分重合或者是第一扫描区域位于通往第二扫描区域的通道中。如图2所示,示出了第一扫描区域和第二扫描区域是重合的示意图。如图3所示,示出了第一扫描区域和第二扫描区域是部分重合的示意图。当红外检测模块103为红外阵列传感器这种高能耗的传感器时,应当将红外热释电传感器101、工作信号生成模块102和红外阵列传感器直接通过同一个PCB主板上的线路进行连接,以避免三个部分分离设置,引起信号传输困难和信号传输滞后的问题。优选的,第一扫描区域和第二扫描区域应当完全重合。In order to make the infrared pyroelectric sensor 101 play the role of pre-detection, the scanning area (first scanning area) of the infrared pyroelectric sensor 101 and the scanning area (second scanning area) of the infrared detection module 103 should be the same adapted. Adaptation here means that the first scanning area overlaps or partially overlaps with the second scanning area, or that the first scanning area is located in a channel leading to the second scanning area. As shown in FIG. 2 , it shows a schematic diagram in which the first scanning area and the second scanning area overlap. As shown in FIG. 3 , it shows a schematic diagram in which the first scanning area and the second scanning area are partially overlapped. When the infrared detection module 103 is a sensor with high energy consumption such as an infrared array sensor, the infrared pyroelectric sensor 101, the working signal generation module 102 and the infrared array sensor should be directly connected through the same circuit on the PCB main board to avoid three The separation of the two parts causes the problems of signal transmission difficulty and signal transmission lag. Preferably, the first scanning area and the second scanning area should completely overlap.
如图4所示,示出了在一个房间内部,两种传感器的扫描区域的位置关系侧视图,人体状态检测装置中红外热释电传感器101的扫描区域(第一扫描区域)是图中左、中、右三个的三角形叠加形成的区域,红外阵列传感器的扫描区域(第二扫描区域)是图中中央位置的三角形的区域。由图4中可见,第二扫描区域是包含在第一扫描区域内部的。通常,红外热释电传感器101的探测距离可达7米,视角接近120°;红外阵列传感器的探测距离可达5米,视角接近60°。红外热释电传感器101和红外阵列传感器是设置在同一个主板上的,并且该主板是设置在房间的顶棚上(图4中三角形的顶点)。As shown in Figure 4, it shows a side view of the positional relationship between the scanning areas of the two sensors in a room, the scanning area (first scanning area) of the infrared pyroelectric sensor 101 in the human body state detection device is the left side of the figure , middle and right triangles are superimposed to form an area, and the scanning area (second scanning area) of the infrared array sensor is the area of the triangle in the center of the figure. It can be seen from FIG. 4 that the second scanning area is contained within the first scanning area. Generally, the detection distance of the infrared pyroelectric sensor 101 can reach 7 meters, and the viewing angle is close to 120°; the detection distance of the infrared array sensor can reach 5 meters, and the viewing angle is close to 60°. The infrared pyroelectric sensor 101 and the infrared array sensor are arranged on the same main board, and the main board is arranged on the ceiling of the room (the apex of the triangle in FIG. 4 ).
由于第二扫描区域完全位于第一扫描区域的内部,进而如果人体(热源的一种)朝红外阵列传感器的扫描区域走去,那么人体首先会被红外热释电传感器101探测到。也就保证了红外热释电传感器101的预检测不会遗漏。Since the second scanning area is completely inside the first scanning area, if a human body (a type of heat source) walks towards the scanning area of the infrared array sensor, the human body will be detected by the infrared pyroelectric sensor 101 first. It also ensures that the pre-detection by the infrared pyroelectric sensor 101 will not be missed.
除了上述两种情况以外,还有一种安装红外热释电传感器101的特殊情况,即第一扫描区域位于通往第二扫描区域的通道中的情况。该种情况下,红外检测模块103的扫描区域(第二扫描区域)是整个房间,如果红外检测模块103是在有行人进入到房间内后开始工作,则红外热释电传感器101可以设置在该房间的入口处(如房门的位置上,以使第一扫描区域能够覆盖进入到房间的通道)。此时,第一扫描区域和第二扫描区域是相邻的(二者没有重合的区域),并且行人进入到第二扫描区域内之前,会经过第一扫描区域。因此,行人在进入到第二扫描区域前,会先经过第一扫描区域,进而红外热释电传感器101会先扫描到行人,并生成红外检测信号,之后工作信号生成模块102会生成工作信号,以驱动红外检测模块103工作。In addition to the above two cases, there is also a special case of installing the infrared pyroelectric sensor 101, that is, the case where the first scanning area is located in the channel leading to the second scanning area. In this case, the scanning area (second scanning area) of the infrared detection module 103 is the entire room, if the infrared detection module 103 starts to work after a pedestrian enters the room, the infrared pyroelectric sensor 101 can be arranged in the room. The entrance of the room (such as the position of the door, so that the first scanning area can cover the passage into the room). At this time, the first scanning area and the second scanning area are adjacent (there is no overlapping area), and pedestrians will pass through the first scanning area before entering the second scanning area. Therefore, before the pedestrian enters the second scanning area, he will first pass through the first scanning area, and then the infrared pyroelectric sensor 101 will scan the pedestrian first, and generate an infrared detection signal, and then the working signal generating module 102 will generate a working signal, To drive the infrared detection module 103 to work.
下面对工作信号生成模块102的工作机制进行说明。前文中已经说明,本方案的核心点在于使用低功耗的红外热释电传感器101来带动高功耗的红外检测模块103进行工作,从而达到降低整体系统能耗的目的。因此,一般情况下,工作信号生成模块102应当是在红外热释电传感器101检测到有人存在的时候(如有温度变化的时候),生成工作信号。The working mechanism of the working signal generating module 102 will be described below. It has been explained above that the core point of this solution is to use the low-power infrared pyroelectric sensor 101 to drive the high-power infrared detection module 103 to work, so as to achieve the purpose of reducing the overall system energy consumption. Therefore, in general, the working signal generation module 102 should generate the working signal when the infrared pyroelectric sensor 101 detects the presence of a person (for example, when there is a temperature change).
下面对红外热释电传感器101的工作原理进行简单说明。红外热释电传感器101是一种利用热释电效应而对温度敏感的传感器。它通常是由陶瓷氧化物或压电晶体组件组成,组件两个表面做成电极,当红外热释电传感器101监测范围内有温度变化时,热释电效应会在两个电极上产生一定量的电荷,即在两电极之间产生一定的微弱电压。经过降噪滤波、放大等处理后,可将检测结果以数字信号的形式进行输出。The working principle of the infrared pyroelectric sensor 101 will be briefly described below. The infrared pyroelectric sensor 101 is a temperature-sensitive sensor utilizing the pyroelectric effect. It is usually composed of ceramic oxide or piezoelectric crystal components, and the two surfaces of the components are made of electrodes. When there is a temperature change within the monitoring range of the infrared pyroelectric sensor 101, a certain amount of pyroelectric effect will be generated on the two electrodes. The charge, that is, a certain weak voltage is generated between the two electrodes. After noise reduction filtering, amplification and other processing, the detection results can be output in the form of digital signals.
由此可见,红外热释电传感器101是能够检测到温度变化的传感器,进而红外热释电传感器101会产生两种信号,分别是温度变化信号(即,红外热释电传感器101进一步用于,当扫描时,检测到扫描范围内有热源移动,则生成温度变化信号)和温度无变化信号(即,红外热释电传感器101进一步用于,当扫描时,没有检测到扫描范围内热源移动,则生成温度无变化信号)。同时,工作信号生成模块102进一步用于当接收到温度变化信号时,生成工作信号。It can be seen that the infrared pyroelectric sensor 101 is a sensor capable of detecting temperature changes, and then the infrared pyroelectric sensor 101 can generate two kinds of signals, which are respectively temperature change signals (that is, the infrared pyroelectric sensor 101 is further used for, When scanning, it is detected that the heat source moves in the scanning range, then generate a temperature change signal) and a temperature no change signal (that is, the infrared pyroelectric sensor 101 is further used for, when scanning, it does not detect that the heat source moves in the scanning range, generates a signal of no change in temperature). Meanwhile, the working signal generating module 102 is further configured to generate a working signal when a temperature change signal is received.
通常,每次红外热释电传感器101进行扫描之后,均会生成红外检测信号,依据设置的不同,可以是检测到有移动热源时输出高电平信号,在没有检测到移动热源时输出低电平信号(或者是不输出信号)。Usually, after the infrared pyroelectric sensor 101 scans each time, an infrared detection signal will be generated. According to different settings, a high-level signal can be output when a moving heat source is detected, and a low-level signal can be output when a moving heat source is not detected. Flat signal (or no output signal).
其中,在某种情况下,工作信号生成模块102可以是指红外热释电传感器101内部生成高电平信号(此时高电平信号即相当于工作信号)的组件,也可以是指独立于红外热释电传感器101的组件。Wherein, under certain circumstances, the working signal generating module 102 may refer to a component that generates a high-level signal inside the infrared pyroelectric sensor 101 (at this time, the high-level signal is equivalent to a working signal), or may refer to a component that is independent of the Components of the infrared pyroelectric sensor 101.
实际工作中,会遇到很多种情况。如,用户可能只是快速的通过检测区域,并未在检测区域停留,此时,虽然红外热释电传感器101会生成温度变化信号,但不应当在只生成一次温度变化信号时直接开启红外检测模块103。针对该种情况,应当将工作信号生成模块102的工作策略进行调整。具体的,工作信号生成模块102包括第一计数器1021,该第一计数器1021用于在接收到温度变化信号时,累计次数加一,并当累计次数超过预设阈值时,生成第一工作信号。也就是,当红外热释电传感器101多次检测到有移动的人时,才会生成第一工作信号,以驱动红外检测模块103工作。In actual work, many situations will be encountered. For example, the user may just pass through the detection area quickly without staying in the detection area. At this time, although the infrared pyroelectric sensor 101 will generate a temperature change signal, the infrared detection module should not be turned on directly when the temperature change signal is only generated once. 103. In view of this situation, the working strategy of the working signal generation module 102 should be adjusted. Specifically, the working signal generating module 102 includes a first counter 1021, and the first counter 1021 is used to add one to the accumulated number when the temperature change signal is received, and generate a first working signal when the accumulated number exceeds a preset threshold. That is, when the infrared pyroelectric sensor 101 detects a moving person multiple times, the first working signal is generated to drive the infrared detection module 103 to work.
同时,如果红外热释电传感器101的检测区域内一直存在静止热源(如静止的人或其他动物等),或者不存在热源的话,则生成的红外检测信号为温度无变化信号,此时,可以依据需要的精度来调整工作信号生成模块102的工作方式。下面分别对针对种情况的工作方式进行说明At the same time, if there is a static heat source (such as a stationary person or other animal) in the detection area of the infrared pyroelectric sensor 101, or if there is no heat source, the generated infrared detection signal is a signal without temperature change. At this time, it can be The working mode of the working signal generating module 102 is adjusted according to the required accuracy. The following describes the working methods for each situation
第一种方式:第一计数器1021进一步用于在接收到温度无变化信号时,生成第二工作信号,并将累计的次数清零。也就是,为了避免漏检,当红外热释电传感器101生成温度无变化信号时,也启动红外检测模块103进行一次扫描。The first way: the first counter 1021 is further configured to generate a second working signal and clear the accumulated number of times when receiving the signal of no temperature change. That is, in order to avoid missed detection, when the infrared pyroelectric sensor 101 generates a signal of no temperature change, the infrared detection module 103 is also activated to perform a scan.
第二种方式:第一计数器1021进一步用于在接收到温度无变化信号时,将累计的次数清零,且不生成工作信号。也就是,在红外热释电传感器101生成温度无变化信号时,不再驱动红外检测模块103工作。The second way: the first counter 1021 is further used to clear the accumulated number of times and not generate a working signal when receiving the signal of no change in temperature. That is, when the infrared pyroelectric sensor 101 generates a signal of no temperature change, the infrared detection module 103 is no longer driven to work.
上述两种工作方式相比较,第一种方式可能会使红外检测模块103在不应当启动的时候启动,但避免了漏检的情况,该种方式适合在人员位置相对稳定的空间内使用,如会议室、教室、卧室灯。第二种方式,降低了系统的能耗,更适合在人员位置经常发生变化的区域使用,如走廊、运输通道等。第二种方式中,除了不生成工作信号外,还会将累计的次数清零,说明,只有连续接收到温度变化信号才会生成工作信号。Compared with the above two working methods, the first method may cause the infrared detection module 103 to start when it should not be started, but avoids the situation of missed detection. This method is suitable for use in a space where the personnel position is relatively stable, such as Conference room, classroom, bedroom lights. The second method reduces the energy consumption of the system and is more suitable for use in areas where personnel positions often change, such as corridors and transportation passages. In the second method, in addition to not generating a working signal, the accumulated times will be cleared, indicating that only when the temperature change signal is received continuously can a working signal be generated.
上述内容介绍了使用低能耗的红外热释电传感器101来启动高能耗的红外检测模块103的启动电路100,该种启动电路100可以应用在使用红外检测模块103的人体状态检测装置中。进而,本申请还提供了人体状态检测装置,如图5、6、9和10所示,该人体状态检测装置包括上述的启动电路100,还包括中央处理器200(MCU)和无线发送模块302,所述中央处理器200分别与红外检测模块103和无线发送模块302连接,中央处理器200,用于对红外检测模块103扫描后生成的结果信号进行预处理,以生成结果信号;无线发送模块302,用于将结果信号发出。The above content introduces the start-up circuit 100 using the low-energy infrared pyroelectric sensor 101 to start the high-energy-consumption infrared detection module 103 .

其中,中央处理器200的预处理过程指的是,将结果信号进行发送前的处理(如打包、封装等常规性操作,下文中的预处理也是相同的含义),这种处理行为已经在相关技术中大量出现,此处不再过多说明。无线发送模块302的具体体现形式可以依据使用的场景进行调整,如可以使用wifi发送单元、BT发送单元、zigbee发送单元等等,也可以是这些发送单元的组合。Wherein, the preprocessing process of the central processing unit 200 refers to the processing before sending the result signal (such as packaging, encapsulation and other routine operations, the preprocessing hereinafter also has the same meaning), and this processing behavior has already been described in related There are a large number of technologies, so I won't explain too much here.

The result signal is preprocessed, and the result signal generated after preprocessing is sent to the wireless sending module 302 .

具体的,电池供电单元402可以由两部分组成,分别是检测电路和电池供电电路,其中,检测电路与适配器供电单元401的输出口连接,用于检测适配器供电单元401的输出口的电流值/电压值,并当检测到的电流值/电压值低于预定数值时驱动电池供电电路向中央处理器200供电。具体的,适配器供电单元401的作用类似于变压器,能够将外部电源(如市电电源)提供的电能进行转换(目的是转换成中央处理器200能够直接使用的电能),并将转换后的电能提供给中央处理器200。Specifically, the battery power supply unit 402 may be composed of two parts, namely a detection circuit and a battery power supply circuit, wherein the detection circuit is connected to the output port of the adapter power supply unit 401 for detecting the current value/ voltage value, and when the detected current value/voltage value is lower than a predetermined value, the battery power supply circuit is driven to supply power to the central processing unit 200 . Specifically, the function of the adapter power supply unit 401 is similar to a transformer, which can convert the electric energy provided by an external power supply (such as a mains power supply) (the purpose is to convert it into electric energy that can be directly used by the central processing unit 200), and convert the converted electric energy provided to the CPU 200.
进一步,还可以将电池供电单元402设计为可充电电池,并为其设置相对应的电池充电管理模块,以实现对可充电电池的充电过程的管理,完成电池的预充、快充、涓流充电等功能。Further, the battery power supply unit 402 can also be designed as a rechargeable battery, and a corresponding battery charging management module can be set for it to realize the management of the charging process of the rechargeable battery, and complete the pre-charging, fast charging, and trickle charging of the battery.
