Simulation test system and method for subway LCU equipment module and relay array module

Abstract

The invention provides a simulation test system and method for a subway LCU equipment module and a relay array module, and the system comprises the steps: enabling the LCU equipment module to execute a control command, and transmitting the instruction and state information of LCU equipment to a simulation test teaching all-in-one machine through a subway LCU real object operation train control logic program; the relay array module executes a control command, realizes relay logic combination with different functions through subway relay physical equipment, and sends an instruction and state information of the relay array module to the simulation test teaching all-in-one machine; the simulation test teaching all-in-one machine interacts with the LCU equipment or the relay array through a simulation module and a test module in the computer, so that analogue simulation, function test and performance test of an LCU equipment program or the relay array are realized, and a teaching function is realized. The system is designed for the same train circuit function, simulation test verification is carried out through the LCU equipment module and the relay array module, and meanwhile, an experiment result can be submitted for a teacher to score.

Description

technical field [0001] The invention relates to the technical field of train electrical control, in particular to a simulation testing system and method for a subway LCU equipment module and a relay array module. Background technique [0002] The functions of the train electrical control circuit in the subway vehicle include train activation, occupancy of the driver's cab, pantograph lifting, closing and opening of the main circuit breaker, train traction blocking, braking control and traction safety control, etc. These functions can be implemented by hard-wired circuits or electronically controlled means. [0003] A large number of existing subway vehicles adopt the relay control method. In this control method, a large number of relays are arranged in each electrical cabinet of the train, and the control functions are completed by these relays. The disadvantage of the above-mentioned existing subway vehicles is that the relay has an operating life. After a long time of swi...

AI Technical Summary

Problems solved by technology

The disadvantage of the above-mentioned existing subway vehicles is that the relay has an operating life. After a long period of switching, the relay will have action adhesion, slow action, or even malfunction. Once these problems occur, troubleshooting is very difficult.

[0007] The disadvantages of the LCU logic control unit system in the above-mentioned prior art are: it is mainly suitable for the test of the LCU equipment, used to assess whether the equipment can support the safe operation of the vehicle, or suitable for the design and development of the LCU product itself, not suitable for teaching experiment
