RBC侧接口监测设备研究

Study on RBC-side Interface Monitoring Equipment

目前,CTCS-3级列控系统车地通信链路监测主要针对通信侧的通道和车载ATP侧的GSM-R接口,而在地面RBC侧无相应监测手段,在发生无线通信超时故障时,无法及时从RBC侧进行故障分析。为此,提出在RBC侧增加PRI接口监测设备,并对其进行了系统设计和功能实现的研究。通过对车地通信数据的采集及链路监测,以及对RBC数据的处理和分析,实现RBC通信及业务数据的智能诊断。该设备在合安高铁试点使用,应用效果良好,可方便维护人员分析无线通信超时故障。

At present,the monitoring over the train-ground communication link of the CTCS-3train control system is mainly focused on the channel on the communication side and the GSM-R interface on the vehicle-mounted ATP side and dose not include the RBC side on the ground.When a wireless communication timeout occurs,fault analysis on the RBC side cannot be carried out in time.Therefore,it is proposed that a PRI interface monitoring device be added on the RBC side and the system design and function realization of the device is studied.Through the collection of trainground communication data,the monitoring of the communication link,and the processing and analysis of RBC data,intelligent diagnosis of RBC communication and service data can be realized.This device has been put into a pilot application in Hefei-Anqing high-speed railway with good application effects and can help maintenance personnel in analyzing wireless communication timeout faults.
