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。
The traditional automatic device simulation method in Dispatcher Training Simulator (DTS) is to model different types of devices separately. The disadvantages are poor adaptability and poor scalability. In response to these problems, the principle of automatic device is analyzed, and a simulation model based on user-defined automatic device is established. The model abstracts the automatic device into three parts: the start-up component, the comprehensive information analysis module and the linkage component, so as to realize the uniform treatment of different automatic devices. The comprehensive information analysis unit uses a logical expression with a custom symbol element and grammar rules to be implemented. The expression is parsed by a specific expression parser to complete the comprehensive analysis and judgment of the start signal. The practical application of DTS in Tianjin shows that the model has good universality, flexibility and scalability.
