现代列车的多微机控制和数据交换技术

Multi-microcomputer Control & Data Exchange technology for Modern Trains

以交流传动电力机车为例，概述了现代机车和旅客列车的多微机控制系统与通信网络。按照控制任务与功能，机车控制系统分为三级：列车控制级、机车控制级和传动控制级。为改善和提高旅行的质量与舒适度，现代列车还配置了旅客信息系统。它由分布在不同地点的微处理器实现。列车通信网络保证各微机之间的信息交换。文中还介绍了现代列车采用的通信网拓扑结构和通信协议。

Citing AC drive electric locomotive as instance, the author generalizes the multi-microcomputer control system and communication network for modern locomotives and passenger trains. Locomotive control system can be divided into three stages in control task and function: train control stage,locomotive control stage and traction control stage. To improve running performance and comfort, modern trains are equipped with passenger information system, which is realized through microprocessors distributed in different locations.Communication network on the train enables information exchange among microprocessors. Topology and agreement of communication adopted by modern trains are also concerned.
