摘　　要：针对高速动车组列车控制网络对输入输出设备的要求,提出了一种具有TRDP和MVB功能的输入输出模块设计方案。该模块主要包含主控制板卡、MVB板卡和多个输入输出板卡,其中主控板卡通过以太网接口可实现TRDP协议的数据传输,也可以通过并行总线访问MVB板卡实现MVB数据传输。上述两种模式可通过软件配置实现切换。主控制板卡通过串行总线对输入输出板卡进行管理。通过试验验证,该模块方案可自动识别板卡类型及数目,便于准确地查找故障,输入输出通道数目具有很强的扩展性,MVB和TRDP的控制方式灵活切换,TRDP通信质量满足现场要求。According to the requirements of high speed EMU for input/output device in train control network,an input/output module design has been proposed.This module mainly contains a master control board,MVB board and multiple input/output boards.The function of TRDP can be achieved using the interface of ethernet in the master control board which can also achieve the function of MVB data transition by accessing MVB board using the parallel bus.The two modes can be switched through the software configuration.The communication and management of the input/output boards can be realized by the master board through the serial bus.The experimental results show that this module can recognize the type and number of the board automatically,which could accurately find the hitch.In addition,the number of input/output channels has better expansibility.The MVB and TRDP modes can be switched flexibly and the communication quality of TRDP satisfies the field application.
