摘要:
基于成都地铁1号线、2号线CBTC(基于通信的列车控制)系统故障数据统计,车载设备故障约占CBTC系统故障总数的75%。对2017年至2019年地铁1号线、2号线CBTC车载设备故障原因进行了分类统计,主要的故障原因为车地无线通信中断、车地无线通信链路异常、丢失信标、加速度计自锁。对以上故障原因进行了分析并提出了相应的解决方案。
Abstracts:
Statistics of CBTC (communication-based train control) system failures on Chengdu Metro Line 1 and Line 2 shows that onboard equipment faults take up 75% of the total CBTC system failures. Causes of CBTC onboard equipment faults of Metro Line 1 and Line 2 from 2017 to 2019 are counted in categories, and the main causes are train-wayside wireless communication interruption, train\|wayside wireless communication link abnormality, loss of beacon, self-locking of accelerometer. Analysis is conducted on these causes and corresponding solutions are put forward.
