摘要
以嵌入式处理器STM32F103为核心,利用GPS定位技术、CAN通信技术、GPRS通信技术设计了一种专门针对农机领域的车载监控终端。该终端能够实现车辆位置信息、行车状态信息的实时采集与远程无线传输;同时,能够处理远程监控中心下达的指令,对车辆进行限速、锁车、设置电子围栏。目前,该终端已经在洛阳某农机公司的农机车辆上进行了应用,运行稳定可靠,为车辆快速故障定位、维修、管理提供了真实数据支撑。
In the paper,a vehicle monitoring terminal for agricultural machinery filed is proposed, which takes STM32F103 as the core and uses GPS positioning technology,CAN communication technology and GPRS communication technology.The terminal can collect the vehicle status information in real-time and transmit it to the remote monitoring center through the wireless network.At the same time,it can handle the instructions from the remote monitoring center which include limiting the speed,locking the vehicle,and setting up electronic fences.It provides the data support for rapid vehicle fault location, maintenance and management.At present, the vehicle terminal has been applied in the agricultural vehicles of an agricultural machinery company in Luoyang and the operation is stable and reliable.
