基于双STM32的行车辅助信息记录装置设计

Design of Driving Assistant Information Recording Device Based on Dual STM32

分析行车监测研究现状,并设计一款多功能且操作简单的行车辅助信息记录装置.该装置具备图像采集、监测车内温度、湿度、气压及车外障碍物距离等功能,并将数据存储于SD卡内,显示在LCD上.选择2个STM32F103ZET6作为主控芯片,配以电源电路、图像采集模块、行车参数监测模块、液晶显示模块和SD卡存储模块,并采用CAN总线通信方式实现主机和从机的通信.实验测试结果表明,该装置模型具有实时显示及拍照、行车参数采集与图像存储等功能.

This paper mainly analyzes the current situation of traffic monitoring research and designs a multi-functional auxiliary information recording device with simple operation.The device boasts the following functions,including capturing images,and supervising the in-car temperature,humidity,air pressure and obstacle distance outside the vehicle and so on.Then,the data is stored in SD cards and displayed on LCD.Two chips named STM32F103ZET6 are used as the main control chips combined with the power circuit,image acquisition module,driving parameter monitoring module,LCD display module and SD card memory module.The communication between the host and the slave is realized by CAN bus communication.The experimental test shows that the device model has the functions of real-time display and photographing,driving parameter collection,picture storage,etc.
