摘　　要：随着汽车走进千家万户,幼童被困车内导致的安全事故不断增多。该文以解决幼童遗留在车内引发的安全事故为目标,采用毫米波雷达模块作为探测核心,MCU为STC12C5A60S2处理器,DS18B20温度传感器、ESP8266等硬件模块作为其组成部分,用户可通过APP远程获得提醒信息,在必要时可远程操作汽车,实现降温、降窗操作,从而避免事故的发生。通过一系列的实验,得到了毫米波雷达模块人员监测的阈值为70,当阈值大于或等于70时,车内有人的概率为99.98%;阈值小于70时,车内有人的概率为0.03%。汽车生命监测系统可应用在智能汽车、家庭看护、密闭空间等领域。As the automobile enters thousands of households,the security incidents caused by the children trapped in the car are increasing.This article aims to solve the safety problems related to children who are left in the car.It adopts millimeter-wave radar module as the core of detection.The STC12C5A60S2 processor is consisted of MCU,DS18B20 temperature sensor,ESP8266 and other hardware modules.Users can access reminder information remotely through the APP and can remotely operate the car to keep the car cool when necessary which is conductive to decrease the advent of disasters.Through a series of experiments,the threshold for personnel monitoring by millimeter-wave radar modules is 70.When the data is greater than or is equal to 70,the probability of people being in-car is 99.98%;If that is less than 70,the probability of people in the car is 0.03%.Automotive life monitoring system can be used in smart cars,home care,confined space and other fields.
