人体检测模块，用于汽车停止运行时，检测车内是否有人，并发出滞留人员信号；人体检测模块采用摄像头加人体图像识别的方式，在车内合适的位置安装带有红外夜视功能的摄像机全天候监视车内情况，应用现有较成熟的人体图像识别算法，通过一系列人体相关的属性分析判断车内是否有人存在，并将判断结果发送给控制模块。若车内有人存在，摄像头将拍下此时车内的照片，并在手机端用户有查看车内情况的需求时将照片传送给用户手机。人体检测模块通过蓝牙 的方式与控制模块进行信息传递。
温度检测模块，用于在确定车内有人员滞留时，开始检测车内温度，并发出车内温度信号；温度检测模块采用非接触式温度传感器在车内多点布控，并将测量得到的温度信号通过端口发送给控制模块进行AD转换处理。
控制模块，与温度检测模块和人体检测模块电连接，用于根据设定的***控制逻辑进行信息处理并控制各个模块工作；控制模块采用现有技术中的单片机，控制模块与车载联网模块间的信息传递通过CAN通信(传递控制信息)和蓝牙(传递图片)实现。
计时模块，设置于控制模块内，计时模块采用现有技术中的计时器，用于在滞留人员信号为有人时，开始计时，并发出滞留时间信号。
运行检测模块，设置于控制模块内，用于检测车辆运行状态，并发出状态信号，此处为现有技术，可直接从车载联网模块中获取车辆运行状态信息；
车载联网模块，电连接于车载空调和控制模块之间，用于响应控制模块发出的信号，并控制车载空调作业；其中，车载联网模块可应用时下热门的车联网技术的核心模块：智能车载终端，即TelematicsBOX，简称车载T-BOX，实现和后台云端服务***/手机APP通信，以及手机APP的车辆信息显示与控制功能。车载T-BOX终端内含一张SIM卡，并配套4G天线、GPS天线等，支持蓝牙、WIFI通信，具有双核处理的OBD模块，双核处理的CPU构架；分别采集汽车总线Dcan、Bcan、Pcan相关的总线数据和私有协议进行反向控制，实现指 令与信息的传递，包括车辆状态信息、控制指令等；通过GPRS网络将数据传出到云服务器(双向通信)，将车体信息主动反馈给用户手机，动态干预以预防事故发生。基于车载T-BOX终端，可实现主动/远程控制车辆空调、拨打电话、与手机通信等功能。当终端处于无信号网络的状态时，需定时记录当前信息(包括温度，人体检测信息，车辆定位，剩余电量等等)，并在网络恢复时通过补报的方式将最新的实时信息发送给云端。
报警模块设置于控制模块内，用于通过车载联网模块的车载SIM卡向公安部门报警，报警内容为设定好的语音报警信息(包括车辆定位，车辆型号与颜色，车牌号等)；以及通过车载联网模块控制车身部件，用于实现汽车鸣笛和闪灯；以及通过车载联网模块云端服务器向用户手机APP发送警报信息。
车载空调，用于驱动汽车空调制冷或制热，通过CAN通信网络与车载联网模块数据连接；车载空调通过CAN网络接收控制指令，执行制冷、制热或关闭的动作，并将空调工作状态实时反馈给控制模块。控制模块内设置有空调控制模块，用于控制空调的启动停止与温度调节，并监控其工作状态。通过分析空调开启后车内温度变化与时间的关系来判断车载空调运行效果，并在效果不佳时将结果反馈给用户。
电源模块，用于为***各电路供电；使用车载电源作为***的供电模块，并将电源的剩余电量信息实时反馈给控制模块。通过CAN通信网络与车载联网模块连接。
电量监控模块，设置于控制模块内，用于检测电源模块所剩电量， 并判断剩余电量情况，确保电源模块的电量足够维持***主要功能的运行和报警。
车载联网模块数据连接云端服务器，云端服务器是基于车载T-BOX终端，应用云技术搭建的信息服务后台，通过GPRS网络连接车体与手机进行信息交互，在后台整合并集中管理用户数据。实现用户实时信息查询，远程控制车辆等功能。当云端服务器与车载终端失联时，将最后一次从车体接收到的信息发送给手机，并提醒手机此时已与车辆失去通信；当云端服务器与用户手机失联时，待手机恢复通信后，将最新一次从车体接收到的信息发送给用户手机模块。用户手机APP将用户的要求与控制命令通过云端服务器和4G网络传递给车载联网模块，车载联网模块通过CAN网络在车内传递要求与控制信息到各个模块；车载联网模块通过CAN网络与其他通信接口(蓝牙)实时获取信息并上传云服务器，云服务器通过4G网络将信息发送到用户手机APP上。
综上所述：
本发明使用时，若停止车辆内困有孩童，通过温度监控和滞留提醒，调节车内温度，提供舒适的生存环境，为救援孩童争取时间，便于关联联系人及时营救被困孩童，在确保遗留孩童生命安全的同时也避免车内财物丢失；通过将车内的温度分级别处理，分别采用提醒启动车载空调、自动启动车载空调和报警工作，实用性更强；通过对车载空调工作的检测，确保车载空调的正常工作，在空调出现故障或者制冷/制热效果不佳时，向关联联系人发送消息，告知关联联系人车 载空调的故障。
