Design and test of commissioning test bed for city D intercity dynamic train
The primary type of vehicle operating on the existing general-speed lines in China is the 160 km/h power centralized rolling stock,which is secure and comfortable with flexible grouping.Current-ly,before leaving the factory,the rolling stock is connected to the vehicle end of the simple tooling to com-plete the test work,using the buttons and indicators to simulate the IO signals connected to the vehicle.The test results are manually entered on paper documents,however,making it impossible to guarantee the data'sobjectivity and traceability.This paper uses the SpringBoot+Vue framework and arm-based embed-ded technology to design a set of intelligent debugging test benches,which simulates the IO test signals of the connected vehicle under software control and completes the testing of hard-wired signals at the end of the vehicle.Through the simulation of the vehicle electrical information centralized unit,collects and parses the Ethernet data on the hard-wired signals to supplement with the network status determination.Additionally,it has the ability to archive,query,and automatically create test reports from the debugging data.The debugging efficiency is significantly increased through the actual testing of 160 dynamic vehicles from a host factory,and the debugging data is saved in real time.This represents a significant attempt at digital reform and innovation in the debugging stage of the train,and it also serves as a significant point of reference for the single-vehicle debugging of high-speed rail and urban rail vehicles.
