DTS中基于用户自定义的自动装置模拟

在调度员培训仿真器（DTS）中传统的自动装置仿真方法是对不同类型的装置分别建模，其缺点是适应性差、扩展性不强。针对这些问题，对自动装置的动作原理进行分析，建立了1个基于用户自定义的自动装置仿真模型。该模型将自动装置抽象为启动元件、信息综合分析单元及联动元件三部分，实现对不同自动装置的统一处理。其信息综合分析单元采用带自定义符号元素和语法规则的逻辑表达式实现，用特定的表达式解析器进行解析，完成对启动信号的综合分析与判断。在天津DTS的实际应用表明，该模型具有较好的通用性、灵活性和可扩展性。

User-defined automation devices simulation in DTS

The traditional method of automation devices simulation in Dispatcher Training Simulator (DTS) simulates each type of devices respectively,which is proved inadequate as the devices become more diverse.This paper proposes a user defined simulation model based on the analysis of automation devices operation mechanism,which abstracts an automation device into three parts:initiationg units,acting units and information processing units,by which means most of the devices can be processed in the same way.The information processing units are implemented with logic expressions with user defined symbols and semantic rules to accomplish analysis and measure of initiating signals.The new method shows good flexibility and extensibility in its implementation in Tianjing DTS.
