Description

Technical Field

[0001] The utility model relates to the field of controller testing, and specifically to a testing device for a driver controller of a rail vehicle. Background Technique

[0002] A driver controller test bench is used to conduct performance tests on driver controllers on railway locomotives, multiple units, and subway vehicles. It is an essential device to ensure the maintenance quality of locomotives and vehicles. Its main functions include testing the logical relationships of each contact of the driver controller, whether the signals output in each handle position are correct, whether the states of each contact are normal, and detecting whether the potentiometer signal output on the driver controller is accurate.

[0003] Since there are many types and different structures of driver controllers, a method of software - defining the interface logical relationship of the driver controller is adopted in the design. As long as the connectors of different types of driver controllers are the same, the same test line can be used for testing, which facilitates the testing. The test bench has the advantages of simple operation, convenient maintenance, long service life, etc., and is applicable to sites that need to check driver controllers, such as locomotive factories, locomotive maintenance depots, etc.

[0004] The existing driver controller test bench usually connects one end of a plug to the test bench and the other end to the driver controller. A monitoring voltage is provided to the driver controller by the test bench to check whether the contacts that should be closed are closed and whether the contacts that should be opened are opened under each handle position of the driver controller. At the same time, the potentiometer voltage (or Gray code value) is detected whether it is normal. By providing a constant current source to the driver controller, the contact resistance of the internal contacts of the driver controller is measured. Due to the long - term and multiple insertions and extractions of the plug during the long - term test process, it is easy to cause loosening at the connection between the plug and the test bench. And the test personnel cannot always press and fix the plug on the test bench, which easily leads to the interruption of the test, thus affecting the test efficiency. Now, a testing device for a driver controller of a rail vehicle is proposed to solve the above problems. Content of the Utility Model

[0005] The utility model aims at the technical problems existing in the prior art and provides a testing device for a driver controller of a rail vehicle.
