Combined test system of rail transit vehicle control equipment based on mvb bus

Abstract

The invention discloses an MVB-bus-based joint testing system for rail transit vehicle control equipment. The MVB-bus-based joint testing system comprises n vehicle control equipment parts, and testing environment system parts and MVB / network gateways in one-to-one correspondence with the vehicle control equipment parts, wherein the testing environment system parts are interconnected through a preset network, the MVB / network gateways are interconnected through the preset network according to a vehicle assembly network typology of the corresponding vehicle control equipment parts, and each MVB / network gateway is connected with the corresponding testing environment system part through the preset network; each testing environment system part is used for simulating a control object of the corresponding vehicle control equipment part and an operating environment of the target vehicle; and the MVB / network gateways are used for converting MVB bus signals of the vehicle control equipment parts into corresponding network signals. The MVB-bus-based joint testing system realizes the effect of carrying out remote system joint tests of finished-vehicle level on all vehicle control equipment distributed in different regions, reduces the debugging risk, shortens the debugging period, and improves product reliability.

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 based on the MVB bus. 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 multifunctional vehicle control bus MVB 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 equipme...

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

[0004] One of the main reasons why rail transit vehicle control equipment cannot be jointly tested is that different vehicle control equipment is generally developed and produced by different companies or different business units of the same company. Therefore, the spatial distribution of vehicle control equipment is far away, and the two Each vehicle control device is even hundreds of miles apart, and the maximum effective transmission distance of the MVB bus is 2000m. After testing, one or several vehicle control devices do not meet the requirements, and each time the newly developed vehicle control equipment needs to be transported to the place, which greatly increases the test cost and debugging cycle, so multiple vehicle control devices cannot be integrated Tests and Combined Tests
