[0002] Urban rail transit signal systems usually consist of two core parts: the automatic train control system (ATC) and the depot signal control system. The ATC system includes the automatic train monitoring system (ATS), the automatic train protection system (ATP) and the automatic train operation system (ATO). These systems are jointly responsible for train interlocking, route control, train interval control, dispatching command, information management, equipment status monitoring and maintenance management, forming an efficient integrated automation system.

[0003] In the prior art, the automatic train protection system (ATP) and the vehicle simulation driving console used for simulation testing of urban rail signal systems are directly connected through various cables. However, during the simulation test, since each device has its own interface points, the shape, function and definition of each interface are different. The type of cable directly connected between the automatic train protection system (ATP) and the vehicle simulation driving console through the interface also needs to be matched and set according to the input and output interfaces, resulting in poor compatibility of the cables between the devices.
