基于毫米波雷达的车内婴幼儿感知系统研究

Research on Perception System of Infant in Car Based on Millimeter Wave Radar

针对当前社会频繁发生的婴幼儿被遗忘在车内的悲剧事件,通过对毫米波雷达的研究,实现对车内密闭空间生命体征的探测,并结合当前5G技术,通过振动传感器、温度传感器,利用TCP与服务器连接,实现温度变化、车内人员生命体征心跳频率,方位、车辆行驶状态等传感器数据的远程传输,服务器根据对数据的分析做出判断,在出现婴幼儿被遗忘在车内的情况下,通过5G传输模组主动向系统预先设定的手机号码实现远程电话报警,通知相关人员快速做出反应,解救被困婴幼儿。

In view of the current society frequent occurrence of the tragic events of infants being forgotten in the car,through the study of millimeter-wave radar,the life signs of the enclosed space in the car can be detected.Combined with the current 5G technology,through the vibration sensor and temperature sensor,using TCP and server link,the temperature changes,the personnel’s vital signs heart rate in the car,sensor data such as orientation and vehicle driving status can be transmitted remotely,and the server makes a judgment based on the analysis of the data.In case of infants being forgotten in the car,through the 5G transmission module,the long-distance telephone alarm to system’s pre-set mobile phone number can be achieved,notifying the relevant personnel to respond quickly and rescue trapped infants.
