城市轨道交通既有车辆段短库线全自动驾驶改造方案研究

Research on Full Automatic Operation Reform for the Existing Depot Short Parking Line of Urban Rail Transit

介绍了目前国际上全自动驾驶系统的应用现状。通过车辆段的全自动改造可以提高既有城市轨道交通线路的全自动运行等级。既有车辆段存在库线长度较短而不能满足全自动唤醒后完成筛选及自动入库精确停车的问题。通过变更计轴区段划分解决唤醒后自动车及非自动车筛选问题;通过安全制动模型的变更及安装局部定位设备后入库停车控制流程的变更来解决自动入库停车的问题。通过仿真测试验证了既有车辆段短库线自动化改造方案的可行性。

The current application status of full automatic operation system in the world is introduced.The full automatic reform of the depot could improve the automatic level of urban rail transit lines,but the existing railway depots have to face problems of automatic wake-up failure,automatic screening and accurate parking difficulties due to.the short depot line length In this paper,the screening problem of automatic and non-automatic vehicle after wake-up is solved by changing the axle-counting section division,and the problem of automatic parking is solved by changing the safety braking model and the parking control process after installing the local positioning equipment.The feasibility of the automation reform for short storage line in the existing vehicle depot is verified through simulation test.
