The device can be applied to multipletypes of motor train units and has good universality, the production organization form is optimized, and the technological level is improved.

Description

technical field [0001] The invention relates to a simulation monitoring device for a reconnection test of an EMU. Background technique [0002] The reconnection routine test is a key item in the performance test of the advanced repair vehicle of the EMU. In the previous maintenance process, it was necessary to wait for other repaired EMUs to conduct the reconnection test between two EMUs. However, due to the number of repaired EMUs Due to the randomness and uncertainty of the repair time, the EMU often faces the problem of no other trains to cooperate with the reconnection test after the repair, which increases the parking time of the EMU depot and affects the progress of the repair. [0003] In view of the above problems, there are currently three solutions to the reconnection simulation test device as follows: in the documents named "CRH5 Automatic Coupler Reconnection Test Simulator" and "Development of Reconnection Experimental Device for Pure Electric Multiple Units", ...

[0002] The reconnection routine test is a key item in the performance test of the advanced repair vehicle of the EMU. In the previous maintenance process, it was necessary to wait for other repaired EMUs to conduct the reconnection test between two EMUs. However, due to the number of repaired EMUs Due to the randomness and uncertainty of the repair time, the EMU often faces the problem of no other trains to cooperate with the reconnection test after the completion of the repair, which increases the parking time of the EMU depot and affects the progress of the repair.

[0003] In view of the above problems, there are currently three solutions to the reconnection simulation test device as follows: in the documents named "CRH5 Automatic Coupler Reconnection Test Simulator" and "Development of Reconnection Experimental Device for Pure Electric Multiple Units", It can only test the continuity of the electrical circuit of the reconnection coupler, but cannot test the communication signal of the reconnection network of the tested EMU, and has obvious defects in the comprehensiveness and reliability of the test

Patent application number 201810164405.7, the patent of the invention name "EMU reconnection test method and device, EMU reconnection test system" mainly focuses on the description of the reconnection test method, each specific implementation plan is not detailed enough, and this method is only applicable to Standardized EMUs have obvious deficiencies in the versatility of the test system
