CAN总线在车辆分布式控制系统中的应用

Application of CAN Bus in Distributed Control System of Railcar

针对轨道车辆分布式控制系统中驱动电机多而分散、系统信息量大、布线复杂、调试不方便等特点,设计了一种基于CAN总线技术的多电机分布式控制系统。通过CAN总线,监控主机和电机驱动节点可直接进行通信,形成分布式网络,简化了系统结构,实现多电机的分散安装和集中控制功能。本文介绍了监控系统的整体结构、工作原理、驱动节点的软/硬件设计。经系统测试和实际运行表明,该系统安装使用方便、工作可靠性较高,达到了设计要求,具有一定的参考和推广价值。

Countering the problems existing in the distributed control system of railcar, such as the condition of excessive and distributed driving motor, many information exchange, complex wiring, and inconvenient installation and debugging, a distributed control system about the multi-motor based on CAN bus is designed, Via CAN-BUS, the monitor host computer and these nodes of driving motor can communicate with each other directly, like a distributed network, The system structure is more concise, The function of distributed setting and concentrated control is realized in this system. The whole structure and principle of system, the hardware circuit, and the software programming were discussed in detail. Practical using shows that this monitor system has the better control effect and is suitable for similar practical engineering.
