The invention discloses an ESP32-based CSI in-vehicle person leaving detection method, and relates to the technical field of vehicle interior person safety protection, ESP32 equipment and a cloud processing platform are included, the ESP32 equipment further comprises an antenna switch, an RF balun, a power amplifier, a receiving low-noise amplifier, a filter and a temperature sensor, and the ESP32 equipment is characterized in that the antenna switch, the RF balun, the power amplifier, the receiving low-noise amplifier, the filter and the temperature sensor are connected with the cloud processing platform. The ESP32 devices directly access CSI and other radio frequency (RF) signals from the microcontroller, the ESP32 devices are arranged at the front position and the rear position in a vehicle in pairs, and Wi-Fi can be established to start working after the ESP32 devices are powered on. In view of detection of the retention problem of people in a vehicle and comprehensive consideration of limited computing power of an intelligent terminal device ESP32, whether children or pets are retained in the vehicle is comprehensively judged from the number of people and the positions of the people, and in addition, a threshold value is set to assist alarm in combination with parameters of a temperature sensor. The effect of preventing child safety is achieved, meanwhile, picture recording cannot be conducted on the private space in the vehicle, and good user privacy is achieved.
本发明公开了一种基于ESP32的CSI车内人员遗留检测方法，涉及交通工具内部人员安全防护技术领域，包括ESP32设备以及云端处理平台，所述ESP32设备还包含天线开关、RF balun、功率放大器、接收低噪声放大器、滤波器、温度传感器，其特征在于，所述ESP32设备从微控制器中直接访问CSI等其他RF（Radio Frequency）信号，所述ESP32设备成对设于车辆内部前后位置，通电后即可建立Wi‑Fi开始工作。针对车内人员滞留问题检测，以及综合考虑到智能终端设备ESP32本身的计算能力有限，确定从人员数量以及人员所在位置综合判定车内是否存在孩童或者宠物的滞留情况，另外结合温度传感器参数，设置阈值辅助警报，起到预防儿童安全的作用，同时不会对车内私密空间进行画面记录，具有良好的用户隐私性。
