全自动驾驶车辆基地列检作业联锁方案研究

Interlocking Scheme for Inspection Operations in FAO Vehicle Base

[目的]不同于传统人工驾驶车辆基地内信号控制权属划分,全自动驾驶条件下,电客车进入车辆基地无人区信号控制均由运营控制中心完成。为了实现全自动驾驶条件下运维无纸化、数字化,需对人员防护系统开关箱进行方案改造设计,结合地铁车辆基地多系统、接口复杂的特点,对人员防护系统与其他系统的联锁条件也进行了方案设计,以实现对电客车驶入车辆基地自动驾驶区内从车辆入库至列检完成的全过程逻辑控制。[方法]结合全自动驾驶运营场景,对停车列检库检修分区划分、检修作业人员防护系统联锁逻辑、列检作业人员走行轨迹以及与安全连锁系统、高压防护系统等的联锁控制进行方案设计。[结果及结论]为此,根据人员防护系统功能特点,对人员防护系统开关箱进行智能化改造,增加行程开关、限位开关,以完成人员防护开关与检修流程及车辆信号的联锁控制;通过检修走行路径规划,结合智能门禁系统设置情况,完成智能发卡柜的平面布置,实现与人员防护系统的逻辑联锁控制;通过人员防护系统与五防系统间防护区域及防护权限任务的划分,完成两系统间的逻辑控制方案设计。

[Objective]Unlike traditional signal control ownership with manual operation vehicle bases,under FAO(fully automatic operation)conditions,signal control for unmanned zones in the vehicle base during vehicle entry is entirely managed by OCC(operations control center).To achieve paperless and digitalized operation-maintenance under FAO conditions,it is necessary to redesign the personnel protection system switch box scheme.Considering the characteristics of multi-system and complex interfaces in metro vehicle base,scheme design is also carried out for interlocking conditions between personnel protection system with other systems,to achieve full-process logical control from vehicle entering vehicle base automated operation zone,to entering garage,until inspection completion.[Method]Based on FAO operational scenarios,scheme design is carried out for the interlocking control concerning maintenance zoning in parking inspection garage,the interlocking logic of maintenance personnel protection system,the train inspection personnel trajectory and safety interlocking system,high-voltage protection system.[Result&Conclusion]According to the functional characteristics of the personnel protection system,the system switch box is intelligently transformed,adding travel switches and limit switches to complete the interlocking control of personnel protection switches,maintenance processes,and vehicle signals.By planning the maintenance personnel trajectory and setting up intelligent access control system,the layout of intelligent card issuance cabinets is completed to achieve logic interlocking control with the personnel protection system.Through the division of protection areas and protection authority tasks between the personnel protection system and the′five prevention′system,a logic control scheme design is completed between the two systems.
