摘要
系统采用77 GHz毫米波雷达作为检测滞留人员传感器,该毫米波雷达可准确感知到人员存在,可通过串口或I/O口输出开关量,并且具有感应可靠性强、灵敏度高、体积小、使用简单、易于嵌入集成等特点。同时搭配CO浓度检测传感器,能够及时感知车内出现的多种危险情况。系统具有联网功能,能够将车内的采集到的数据发送到用户端以及保存在云端,并通过检测车内人员被困时间及时进行通风和灯光闪烁求救等操作。
The system uses 77 GHz millimeter wave radar as a sensor for detecting stranded people, which can accurately sense the presence of people. It can output switch value through serial port or I/O port, and has the characteristics of strong induction reliability,high sensitivity, small size, simple use, and easy embedded integration. At the same time, with the CO concentration detection sensor, it can timely sense a variety of dangerous situations in the vehicle. The system has networking function and can send the collected data in the car to the client and save them in the cloud, through the detection of the trapped time of the occupants in the vehicle, the operation such as ventilation and flashing lights for help should be carried out in time.
