Regulating and testing technological process for motor train unit traction system

Abstract

A motor train set traction system testing and measuring technology utilizes a cable tester to test the parameters of the network communication lines MVB and WTB of a train and connects a notebook computer with a train MPU to test the variables of the network communication lines MVB, WTB, CAN, thereby improving working efficiency, eliminating the error generated by artificial test, and confirming the communication quality and performance indexes of the network lines, to confirm the performance of a train traction network system and the operation stability of the train.

Description

Debugging Technology of EMU Traction System technical field The invention relates to a debugging process for a traction system of a 200-kilometer-per-hour bullet train. Background technique Modern rail transit technology is mainly marked by high-speed passenger transport and heavy freight. Among them, car body technology, bogie technology, braking technology, AC drive technology, traction control system and rail vehicle system integration technology related to the rail transit equipment manufacturing industry It is the main technical feature of modern rail transit. The high-speed EMU with a speed of 200 kilometers per hour adopts the method of power dispersion. Among the nine key technologies, the traction control system is the core. The technology is complex. How to ensure the performance of the traction system and deliver satisfactory products to users has become the focus and subject of the entire commissioning. The original debugging method is: proofread the lines in...

AI Technical Summary

Problems solved by technology

The original debugging method is: proofread the lines involved in the traction system, test the involved relays and various circuits, such as during the traction debugging process, it is necessary to check the low-voltage power supply, medium-voltage power supply, and main circuit breaker of the vehicle traction system. Test items such as the closure of the pantograph, the starting circuit of the pantograph, the signal test of the driver's station, the power supply and signal of the I / O module, the power supply and signal of the traction converter, the power supply and signal of the auxiliary converter, and the operation of the charger. The traction system of the EMU with a speed of 200 kilometers per hour is based on network control. The wiring of the vehicle has increased the train bus WTB and the vehicle bus MVB. The original debugging process and testing tools cannot detect the wiring quality and performance of the vehicle communication line. indicators, cannot meet the debugging process of high-speed train traction system, and cannot meet the performance requirements of the overall vehicle
