提出了一种基于CAN(Controller Area Network)总线和工业以太网的轻轨列车微机控制系统的远程监控系统。介绍了基于高性能数字信号处理器TMS320C2812的CAN总线和工业以太网的硬件接口电路,讨论了CAN/Ethernet网关模型,以及CAN现场总线和工业以太网的现场网关设计,并应用LabVIEW完成了上层监控界面的设计,实现了微机控制系统中底层控制单元与远程控制中心的实时监控和数据传输。
A remote monitoring system based on CAN (Controller Area Network) bus and industrial Ethernet for light rail train microcomputer control system is proposed. The hardware interface circuit of CAN bus and industrial Ethernet based on high performance digital signal processor TMS320C2812 is introduced. The CAN / Ethernet gateway model, on-the-spot gateway design of CAN field bus and industrial Ethernet are discussed. The upper layer monitoring The interface design realizes the real-time monitoring and data transmission of the bottom control unit and the remote control center in the microcomputer control system.
