Problems solved by technology

[0004] At present, the maintenance personnel of most locomotive depots in China only rely on simple instrument tests combined with manual fault diagnosis for the faults of RIM modules and TRIM modules. Therefore, traditional testing methods are difficult to meet the requirements of improving testing efficiency and maintenance time

Abstract

The invention provides a testing device of a TRIM module and an RIM module based on a virtual instrument. The testing device of the TRIM module and the RIM module based on the virtual instrument is characterized in that a power source sensor, a voltage sensor and a data acquisition card are included, a virtual instrument testing system which is composed of a current source, a voltage source and a control processing part is combined with a testing structure which is composed of a TRIM module plug, an RIM module plug, a relay switch plate, a time test circuit, a signal code circuit and a signal processing circuit, and thus the bounce time of a relay, the resistance value of a resistor and logic line faults in the TRIM module and the RIM module can be diagnosed automatically and manually; afterwards, the control processing part is used for conducting the follow-up work such as arranging, displaying and storing on an obtained test result, and the faults of the TRIM module and the RIM module can be evaluated, diagnosed and analyzed. The data collecting speed is high, the efficiency difference of manual measurement is removed, unreliable errors are also removed, testing precision is high, repeatability is good, testing efficiency is greatly improved, and the reliability is improved.

Description

technical field [0001] The invention relates to a test device, in particular to a relay module test device based on a virtual instrument. Background technique [0002] TRIM module and RIM module are communication modules applied to Shaoshan Type 4 electric locomotive. There are relays inside TRIM module and RIM module. Therefore, the performance of the relay will directly affect the normal operation of the communication module. [0003] When the electric locomotive is running, the most advanced distributed power system (LOCOTROL) will be used to start the front and rear distributed power of the electric locomotive, or the front, middle and rear distributed power system to avoid pulling forward and backward Accidents happen. Therefore, based on the importance of the TRIM module and RIM module in locomotive communication, the measurement of the TRIM module and RIM module is very important. How to accurately detect the electrical parameters of the relay and judge the performan...
