摘要

在研究WTB总线协议网络数据传输特性的基础上，提出一种协调控制周期数据和非周期数据传输的PMTS调度策略；采用实时控制系统的调度理论和控制策略，实时构建周期数据调度轮询机制，设计非周期数据动态抢占调度控制方法，从而实现对网络数据传输的协同控制和调度；搭建WTB总线协议网络数据传输试验平台，将PMTS调度策略应用于自主设计的列车通信网关系统中。结果表明，该调度策略可灵活分配WTB总线网络编组的常规运行周期，实现底层数据传输与上层协议间的协同配合。

Abstract

Based on the research of WTB bus protocol network data transmission characteristics, a PMTS scheduling strategy for coordinated control of periodic data and aperiodic data transmission was proposed. Using the scheduling theory and control strategy of real-time control systems, a periodic data scheduling and polling mechanism was constructed in real time, and a non-periodic data dynamic preemption scheduling control method is designed so as to achieve coordinated control and scheduling of network data transmission. The WTB bus protocol network data transmission experimental platform was set up, and the PMTS scheduling strategy was applied to the independently designed train communication gateway system. The result shows that the scheduling strategy could flexibly allocate the normal operation cycle of the WTB bus network grouping, and the cooperation between the underlying data transmission and the upper protocol was realized.
