Abstract

The invention discloses a ground testing device for an electrical element of a rail vehicle. The ground testing device comprises a frame, wherein an industrial personal computer is arranged in the frame; the industrial personal computer is respectively connected with a display, an I (input)/O (output) board card, a D (digital)/A (analogue) board card, an A/D board card and a printer; and the I/O board card, the D/A board card and the A/D board card are connected with a matrix unit circuit, and the matrix unit circuit is respectively connected with a program control multi-path constant current source, a program control voltage source, a voltmeter, an ampere meter and a tested experimental platform. The invention also discloses a method for testing an electric element by the testing device. More than 16 electric elements can be tested at the same time, and the testing process is automated. A configured test and control board card, a sensor and the like are high-speed and high-precision, high in reliability of tested data, can fast judge the condition of the tested object by matching with analysis software and artificial missing judgment or error judgment can be reduced, so that the test quality and labor productivity can be greatly improved, and the production cost can be reduced.

Description

technical field [0001] The invention relates to a rail vehicle testing device in the field of automatic detection, in particular to a ground testing device and a testing method for rail vehicle electric components used in EMUs and subway vehicles. Background technique [0002] There are many ways to test electrical components such as relays, contactors, and circuit breakers of EMUs and subway vehicles on the ground. The main method is to use a multimeter to measure the resistance value and on-off. For electrical components with higher requirements, use a contact resistance measuring instrument, etc. Special instrument measurement. [0003] Most of these testing methods rely on manual judgment, and the error rate is high; and only one component can be tested at a time, the labor productivity is low, and the test parameters are few, which cannot fully reflect the quality of electrical components. Contents of the invention [0004] Purpose of the invention: the purpose of th...
