Creation and Application of Vehicle Simulator Based on On-board ATC System.

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 aff ected 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. [ABSTRACT FROM AUTHOR]
