摘要
针对当前大多数监测系统采用CAN网络通信而日益暴露出的不足,如多协议CAN设备兼容性差、CAN通信距离及速率受限等,设计了一种嵌入式CAN-Ethernet智能网关,通过移植工业以太网协议,向下兼容多协议的CAN设备网络,向上无缝接入办公以太网,实现实时监测,并创新性地将其集成于采集数据的嵌入式微处理器AT91RM9200中,具有兼容性好、抗干扰能力强、传输速率高和灵活便携等特点,同时大大降低了监测系统的成本。
At present , most of the monitoring system use CAN network to transmit information, but it increasingly exposed some shortcomings, such as the poor compatibility of multi-- protocol CAN devices and its limited transmission distance and speed. So an embedded CAN--Ethernet Intelligent Gateway is designed. Porting the Ethe/＇Net/IP （Ethernet Industrial Protocol） , the gateway which is compatible with the CAN network and connects upward with Ethernet seamlessly can realize Real--time monitoring. And it is integrated in the embed- ded microprocessor AT91RM9200 which is used for data acquisition. It has the advantage of good compatibility and anti--interference capa- bility, high transfer rate, portability and low cost.
