摘　　要：通过分析轨道车辆网络通信系统特点,提出适用于轨道车辆网络系统的静态调度RM(Rate Monotonic)机制;然后通过分析轨道车辆网络控制系统特点,提出适用于轨道车辆网络控制系统的数据传输周期选取方法;最后结合网络性能设计和控制性能设计,提出不同性能要求下,基于静态调度机制的轨道车辆网络控制系统整体优化设计方案,并通过实例进行说明。本文研究为轨道车辆网络控制系统的优化设计提供参考。According to the characteristics of the network communication system of rail vehicles, the static scheduling mechanism applied to the vehicles is proposed. According to the characteristics of the network con- trol system of rail vehicles, the method for data transfer period selection applied to the vehicles is proposed. Combining the network performance and control performance and setting different performance requirements, the optimized design scheme based on the static scheduling mechanism for the networked control system of rail vehicles is proposed. The scheme is explained by an example. Theoretical guidance is provided for optimized design of the networked control system for rail vehicles.
