摘要:
介绍了上海轨道交通9号线CBTC(基于通信的列车控制)系统通信丢失事件案例的基本情况，综合运用车地无线通信原理和现场电磁环境监测数据，分析得到发生该故障的根本原因是受外部信号干扰。从设备更新、管理配套角度，提出了加速推进1.8 GHz频段无线综合承载改造、增强沿线既有无线设备的抗干扰能力、健全无线电管理机制、提升电磁环境监测能力、加强与外部单位和职能部门的联动等应对措施。
Abstracts:
The investigation information of CBTC (communication-based train control) communication loss issue for Shanghai Rail Transit Line 9 is introduced. By comprehensively adopting train-wayside wireless communication principle and the field electromagnetic environment monitoring result, it is analyzed that the root cause of the failure occurrence is external signal interference. From the perspective of equipment renewal and management support, countermeasures are put forward, such as accelerating the comprehensive wireless bearing construction in 1.8 GHz band, enhancing the antiinterference ability of existing wireless equipment along the line, perfecting the radio management mechanism, improving the electromagnetic environment monitoring ability, and strengthening the interaction with external units and functional departments.
