摘要
ATC信号设备是控制机车车辆(地铁)的重要设备,车载系统与车辆的控制电路系统紧密联系,之间存在许多电气接口和信息接口。由于车载ATC信号设备与车辆属于两个系统,系统之间联合调试工作受时间、场地等诸多因素影响,而目前还没有能单独检测车载板卡内部开关量功能的设备,缺少专用工具对中大修后的板卡进行功能验证,在静态检修后的试车线动调时存在安全风险。研究一种替代车辆专业设备的调试装置,该装置与int连接器母头相连,列车静态条件下通过电脑OMAP软件强制驱动板卡内部开关量,从而测试板卡内部接点是否正常工作,在列车动态测试前就能精准定位故障件,提升列车动态调试效率,进一步提高检修质量与标准。
ATC signal equipment is an important equipment for controlling rolling stock(subways).The on-board system is closely connected with the control circuit system of the vehicle,and there are many electrical interfaces and information interfaces between them.As the on-board ATC signal equipment and the vehicle belong to two systems,the joint debugging between the systems is affected by many factors such as time,site and so on.At present,there is no equipment available that can independently detect the internal digital signal functions of the boards and cards onboard the vehicle,and there is a lack of special tools to verify the functions of the boards and cards after medium and large-scale overhaul.There are safety risks during the dynamic debugging on the test line after static overhaul.This paper mainly describes a debugging device that replaces professional vehicle equipment.The device is connected with the female head of int connector.Under the static condition of the train,OMAP software is used to force and drive the internal digital signal of the board or card,so as to test whether the internal contact of the board or card works normally.The positions of faulty components can be accurately identified before dynamic train testing.This device improves the efficiency of dynamic train debugging and further improves the maintenance quality and standard。
