基于ARM处理器的网关通信模块研制

摘要

In order to make the equipments with CAN interface to be conveniently connected with network of locomotivei ARM7 kernel chip LPC2294 was adopted for the realization of MVB-CAN two-way gateway module. The implementation method of hardware interfaces between ARM processor LPC2294 and CAN bus, and between LPC2294 and MVBC02 is presented. The relevant reliability testing and the test in locomotive field were conducted. The results indicate that the gateway can completely meet the design request. The gateway module designed by this method has high reliability and better cost performance.%为了满足机车车辆上具有CAN接口的设备方便接入机车车辆网络,采用ARM7内核芯片LPC2294,实现了MVB-CAN双向网关通信模块.给出了ARM处理器LPC2294与CAN总线、MVB通信芯片MVBC02芯片的硬件接口实现方法,做了相关可靠性测试和现场装车考核试验.结果表明,网关模块完全可以满足设计要求,到达了实际设计效果,设计出的网关模块具有可靠性高,性价比高的特点
