地铁列车数据采集网络系统的设计与实现

Design and Realization of Data Acquisition Network System of Subway Train

针对地铁列车这个特殊的应用对象,开发了一个专门的数据采集网络系统。详细介绍了该系统的组成、工作原理及通信方式,重点放在其特别之处。并列举了该系统中的一个接口实例,介绍了其通信规范、帧的类型与格式、传输时序与控制流程等。运营结果表明该系统能稳定可靠地工作,满足设计的要求。

A special data acquisition network system be developed, aiming at the special application object of subway train. The paper in detail introduces its structure, working principle and communication modes, focuses on the specialization. Furthermore, the paper lists an example of interface. It introduces its communication protocol, frame type and format, transfer timing and control flow, etc. Operation shows that the system works stably and reliably, and meets design's demand.
