基于Agent的轨道交通ATS系统仿真方法研究

Research of Agent-based Mass Transit ATS Simulation System

针对前人轨道交通列车自动监控(ATS)系统仿真方法的不足和ATS自身的特点,提出采用Agent技术研制ATS仿真系统。建立了基于Agent的ATS仿真系统结构,系统中的SCC-Agent的结构模型,并研究了它的形式化定义,行为模式,语义描述,控制流程和内部决策机理。介绍了系统的功能和监控界面。其研究方法降低了ATS仿真系统设计的复杂程度,使系统具有更好的分布性,灵活性,可重用性和可扩展性。目前,系统运行良好,在轨道交通自动控制(ATC)系统设备国产化研究中起到了重要作用。

Considering the disadvantage of traditional simulation method of the transit Automatic Train Supervision (ATS) system and the characteristics of ATS, an ATS simulation system is researched by using the Agent technique. System framework of ATS simulation system based on multi-Agent is proposed. The structure model, formalized define, behavior mode, symbol describing, control process and decision-making mechanism of SCC-Agent are studied. Performance and supervision interface of this simulation system are also presented. The difficulty of system design is reduced greatly using Agent theory. It also makes simulation system to be high distributing, agility, reusability and expansibility. Now the system runs well and plays an important role in national research of transit Automatic Train Control (ATC) system.
