Abstract

The invention discloses a function test bench for a general electric control unit of a locomotive. The test bench comprises a control cabinet, a test cabinet, an inter-cabinet cable and a workbench. The control cabinet comprises an integrated digital quantity output board card, a MVB communication board card, an industrial personal computer of an FIP communication board card, a program control power supply, an electronic load, a power amplifier, a relay matrix, a relay, a connector panel and a USB modular instrument. The test cabinet comprises a tested locomotive electric control unit and a connector panel, and the industrial personal computer performs data interaction with the tested locomotive electric control unit through RS232, MVB and FIP communication, controls the relay matrix through the digital quantity output board card, and controls a program control instrument through serial communication, thereby realizing the function test and simulation of the tested locomotive electric control unit. The function test bench is high in integration level and is easy to maintain and expand functions, has the advantages of being high in test bench utilization rate, low in site space occupancy rate and small in device management workload, and can meet the requirements for automatic testing of various locomotive control units.

Description

technical field [0001] The invention relates to the field of test devices, in particular to a function test bench for a general electronic control unit of a locomotive. Background technique [0002] The locomotive electronic control unit test bench is used to detect the performance and parameters of the electronic control unit, determine the technical status of the electronic control unit, and plays an important role in the maintenance and manufacturing industry of the electronic control unit of the locomotive. The existing locomotive electronic control unit test bench is designed for a single locomotive electronic control unit, which has the disadvantages of low utilization rate of the test bench, high site space occupation rate, and heavy equipment management workload. At present, there is no general test bench in China that can test various locomotive ECUs. Contents of the invention [0003] The invention provides a functional test bench for a general electric control ...
