Abstract

The invention provides an off-line detection system and method for a subway train traction control unit. The off-line detection system comprises a detection unit, an industrial personal computer, a programmable power supply and the traction control unit. The detection unit is connected with the industrial personal computer; the traction control unit is connected with the programmable power supply; and the programmable power supply is connected with the industrial personal computer. The working condition and the control flow of the traction control unit are fully considered, the actual working condition and the operation state of the traction control unit are simulated, function testing and fault diagnosis of the traction control unit are achieved, and rapid function testing and fault detection can be achieved. Meanwhile, through the off-line detection, a large amount of line occupation time is saved, the installation operation difficulty and the like are simplified, and therefore cost is saved, efficiency is improved, and the system operation capacity and the maintenance support capacity of the urban rail transit are greatly improved.

Description

technical field [0001] The invention relates to the technical field of offline detection, in particular to an offline detection system and method for a traction control unit of a subway train. Background technique [0002] The ONIX1500 series traction inverters used in Shanghai subway trains are produced by Alstom, France, and are currently used in subway lines 1, 3, and 5. Among them, the traction control unit in the traction inverter is the core of the traction system. After many years of operation, the traction control unit has continued to fail, and the control unit testing equipment BTE (Bench Test Equipment) provided by the vehicle manufacturer is not only expensive, but also occupies a large area and is not easy to carry. [0003] In the process of overhauling the train frame, the systemic function test and fault detection of the key unit of the traction control unit need to be developed and equipped with related test equipment and testing instruments to meet the req...
