车站计算机联锁系统建模及实现

Modeling and realization of railway station computer interlocking system

铁路计算机联锁系统实时监视进路相关设备从而完成进路控制,是车站列车技术作业自动化的前提。为保证计算机联锁系统安全可靠,本文基于面向对象思想进行车站联锁系统建模,进而实现进路控制的实例化。首先,本文基于面向对象技术进行车站联锁设备属性和系统作业机理分析;在此基础上分析不同车站技术作业的进路需求,利用标准建模语言描述关键车站联锁设备、设备间联锁关系、车站进路控制业务逻辑以及与进路的匹配关系;最后利用Python语言实现车站进路控制自动化,以满足车站设备状态、业务约束及其效率需求,实现计算机联锁自动化。

The railway computer interlocking system monitors the relevant equipment of the route in real time and completes the route control,which is the premise of the technical operation automation of the station train.In order to ensure the safety and reliability of the computer interlocking system,the station interlocking system is modeled based on the object-oriented idea,and then the instantiation of route control is realized.First of all,based on object-oriented technology,this paper analyzes the attribute of station interlocking equipment and system operation mechanism.On this basis,the route requirements of different station technical operations are analyzed,and UML is used to describe the key station interlocking equipment,the interlocking relationship between the equipment,the logic of station route control service,and the matching relationship with the route.Finally,Python language is used to realize the key service that automate the station route control to meet the goal of computer interlocking automation such as status of station equipment,service constraints and efficiency requirements.
