A combined test system for rail transit vehicle control equipment

Abstract

The invention discloses a combined test system of a rail transit vehicle control device. The combined test system of the rail transit vehicle control device comprises a to-be-tested vehicle control device part, a signal conditioning part, a bus converting unit, a vehicle control bus and a simulated system part, wherein the to-be-tested vehicle control device part comprises a plurality of preset vehicle control devices for controlling a whole vehicle; the vehicle control devices are connected through the vehicle control bus according to a vehicle loading network topology; the bus converting unit is used for converting a signal on the vehicle control bus into a bus signal capable of being recognized by the simulated system part; the signal conditioning part is used for converting an external interface signal of the vehicle control device corresponding to the to-be-tested vehicle control device part into a control signal capable of being recognized by the simulated system part; the simulated system part is used for simulating control object information of the to-be-tested vehicle control device part and an external operation environment of a to-be-tested vehicle. The system combined test of different vehicle control devices is realized, the testing adequacy is realized, the debugging risk is reduced, the debugging period is shortened, and the product reliability is improved.

Description

technical field [0001] The invention relates to the technical field of rail traffic control, in particular to a combined test system for rail traffic vehicle control equipment. Background technique [0002] With the rapid development of rail transit, the functions of rail transit products are becoming more and more complex, and people's requirements for the reliability of rail transit products are also getting higher and higher. As an important part of rail transit products, software system's quality and reliability directly affect the reliability of rail vehicles. Software testing can effectively find defects and faults in software. [0003] Rail transit vehicle control equipment is generally interconnected through the vehicle control bus and the train line (train-level hard line) to jointly complete the control function of the entire vehicle. At present, some companies in the field of rail transit have tested their control equipment and software products before loading p...

AI Technical Summary

Problems solved by technology

At present, some companies in the field of rail transit have tested their control equipment and software products before loading products, but before loading, there has not been a comprehensive system joint test between different control systems. At present, the system joint test mainly Replaced by on-site debugging after loading, this method first increases the cycle of on-site debugging and increases the cost of debugging; second, the software product is loaded and debugged without sufficient testing, and there are certain safety risks; Third, with the method of on-site debugging, some destructive and risky scenarios cannot be tested, resulting in insufficient testing
