基于STM32的汽车故障信息采集节点设计

汽车故障检测和诊断技术一直是国内外研究的热点。为了解决汽车维修行业远程故障检测问题，利用OBDII、GPRS和GPS等技术设计实现汽车故障信息采集节点。该节点以STM32F103为中心，包含OBDII转换模块、GPRS模块和GPS模块，实现汽车故障码、时间、经度、纬度、行车速度等信息的采集、处理和暂存，并通过无线通信将信息发送到汽车维护管理中心。实验结果表明，该节点性能较稳定，有较大的实用价值。

Design of Automobile Fault Information Acquisition Node Based on STM32

Automobile fault detection and diagnosis technology has always been a hot topic for the foreign and domestic scholars. In order to solve the problem of remote fault detection for auto repair,designs and implements a vehicle fault information collection node,using such tech-nology as OBDII、GPRS and GPS. The node is based on STM32F103. Uses ODBII module,GPRS module and GPS module,it can acqui-sition automobile fault information,longitude,latitude,speed,and then process,store them. Afterwards,the information is sent to mainte-nance management center by radio. Test results show that this node has steady performance and high practicality.
