摘要: 目标控制器是下一代列控系统中重要的地面设备,它是轨旁信号设备的执行单元,控制信号设备的开关和转换,承担命令信息执行和信号设备状态采集的任务,其数据的正确传输对列车运行安全起着重要作用。针对下一代列车运行控制系统中分布式目标控制器特点和其通信需求,提出一种适用于分布式目标控制器通信子系统设计方法,并对设计的通信总线进行实验验证,实验结果表明,所设计的通信总线的通信时延能保持在20 ms以内,满足通信需求。Abstract: The object controllers in train control system are the important ground equipment in the next generation of train control system. They are the execution units of trackside signal equipment which control the signal equipment switching and transforming, meanwhile, undertake the task of executing command information and getting status of signal device. The correction of the data transmission plays an important role in the safe operation of trains. Aiming at the characteristics of distributed object controller in the next generation of train control system and its demand, this paper proposed a design method of communication subsystem for distributed object controller, verified the designed communication bus. Experimental result shows that the communication delay of the designed communication bus can be less than 20 ms which meets the communication requirements.
