基于北斗的重载铁路列控系统新增功能测试方法

Test Method of New Functions of Heavy Haul Railway Train Control System Based on Beidou

针对仅站内覆盖无线网络条件下的基于北斗的重载铁路列控系统的测试方法进行研究,在站内有无线网络覆盖条件下,通过车站级的数据管理控制设备结合列车的站内位置及联锁状态、临时限速状态信息,生成列车的行车曲线管理列车安全运行。当列车出站后在未覆盖无线网络条件下,通过北斗应急通信短报文的方式与区间内列车确认列控数据一致性。基于北斗的重载铁路列控系统相较于传统列控系统在功能上有较多创新,因此对于其中变化功能的识别,以及测试方法的研究存在其必要性。

This paper studies the test method of the heavy haul railway train control system based on Beidou under the condition of wireless network coverage only in stations.Under this condition,the train operation curves are generated to manage the safe operation of trains by the data management and control equipment at the station level through the combination of the information about a train's position in the station,interlocking state and temporary speed restriction state.When the train leaves the station and the wireless network coverage is not available,information is sent to the train in the section by means of short messages of Beidou emergency communication in order to confirm the consistency of train control data.Compared with the traditional train control systems,this heavy haul railway train control system based on Beidou has many innovations in functions,so it is necessary to identify the changed functions and study the test methods.
