摘　　要：针对停车车辆缺乏远距离实时报警的问题,文中提出一种可以远程向手机发送车内高温、车辆移动及人员进入等报警信息的远程车辆报警系统。该系统由STM32F103ZET6芯片搭配最小系统作为主控模块,接收来自ATK-MPU6050传感器模块和树莓派人脸检测模块的数据以及高电平信号进行报警判断。通过在树莓派中嵌入OpenCV计算机视觉库调用配置Haar级联检测进行人脸检测;通过对ATK-MPU6050传感器模块中MEMS陀螺仪数据、加速度传感器数据和温度传感器数据进行数据解算、位移和温度等检测;通过GSM无线通信模块实现对手机发送移动、高温、人脸检测等警报信息的功能。最后,在实验平台进行多次测试。结果表明,文中系统能够在稳定手机信号覆盖的情况下进行车内高温、人脸检测、车辆位移等报警信号的实时传输,可有效解决车辆停车时的远距离报警问题。In allusion to the lack of long-distance real-time alarm for parked vehicles,a long-distance vehicle alarm system that can remotely send alarm information such as high temperature in the car,vehicle movement and personnel entry to mobile phones. In the system,STM32F103ZET6 chip is matched with the smallest system as the main control module to receive data and high-level signals from the ATK-MPU6050 sensor module and the Raspberry Pi face detection module for alarm judgment.The OpenCV computer vision library is embedded in the Raspberry Pi to calling the configuration of Haar cascade detection for the face detection. The MEMS gyroscope data,acceleration sensor data and temperature sensor data in ATK-MPU6050 sensor module are solved for displacement detection and temperature detection. The alarm information functions such as mobile,high temperature,and face detection can be sent to the mobile phone by means of the GSM wireless communication module. After several tests on the experimental platform,the results show that the system can perform high temperature and face detection under the condition of stable mobile phone signal coverage. The real-time transmission of alarm signals such as detection and vehicle displacement can effectively improve long-distance alarm when the vehicle is parking.
