大容量RTU系统遥信采集实时性问题研究

本文针对电气化铁道牵引供电运动监控系统中运方数据采集和控制单元，分析了目前影响ＲＴＵ系统遥信采集实时性能的主要原因，指出了对大容量ＲＴＵ系统，缩短遥信采集任务处理时间的必要。本文还提出了四种提高ＲＴＵ系统实时性的改进方案，并对这些方案加以较详细的论述。

A Research on Improving Real-Time Ability for High-Capacity RTU System

In this paper authors analyzed the main reason which exerte an influence on the real-time ability of state-signal collection in remote terminal unit(RTU)in the railway telecontrol system,and pointed out that it is necessary to shorten the processing time of state-signal collection for high-capacity RTU system.On basis of analyzing,four approaches are put forward and discussed to improve the real-time ability of state-signal collection in RTU system.
