摘要
CAN总线作为一种先进的现场总线日益得到广泛的应用;GPRS为国内覆盖范围最大的公共无线数据通信网。提出了一种基于CAN总线和GPRS技术的无线数传系统,给出了其软硬件设计方案,并对CAN接口中断处理、GPRS无线数据传输以及CAN通用应用层协议的开发等关键技术问题进行了研究,试验表明系统运行效果良好。
CANbusasakindofadvancedfieldbusisincreasinglyemployed, whileGPRSisapublicwirelessdatanetworkofdomestic largest scale. A wireless data transmission system based on CAN bus and GPRS is designed. The hardware/soft-ware design scheme of system is posed. An in-depth study is carried out about interrupt processing of CAN interface, GPRS wireless data transmission and development of application layer protocol of CAN bus. The experiments indicated that the data transmission system run smoothly.
