Simulation test method for function of closing safety loop of sliding plug door of motor train unit

Abstract

The invention relates to a simulation test method for a function of closing a safety loop of a sliding plug door of a motor train unit. The method comprises a step of verifying the function of closingthe safety loop of the sliding plug door of the whole motor train unit and a step of verifying the function of closing the safety loop of a single sliding plug door in sequence, wherein in the step of verifying the function of closing the safety loop of the single sliding plug door, a sliding plug door simulation debugging device is connected in series to the tested safety loop of the single sliding plug door, the opening and closing of the tested safety loop of the single sliding plug door can be simulated by operating the sliding plug door simulation debugging device, a specific door safetyloop fault is accurately reported on a cab monitoring screen, and a driver is guided to isolate a fault door, so that the safety loop of the sliding plug door of the whole motor train unit is recovered to normal, and the driving safety is ensured; and meanwhile, by utilizing the test method, the safety loop of the single sliding plug door can be verified one by one, the failure rate of vehicles leaving a factory is reduced, and the influence on the driving safety due to incomplete test is avoided.

Description

technical field [0001] The invention relates to the technical field of EMU testing, in particular to a simulation test method for a safety loop function of a plug door of an EMU. Background technique [0002] During the operation of the vehicle, the sliding door is a key system, and the failure of some limit switches (including the limit switch of the closed position, the limit switch of the door lock position, etc.) will cause the safety loop to be disconnected when the sliding door is closed. If the test If it is not in place, after the fault occurs, the driver will not be able to accurately judge the position of the specific fault door to isolate the fault door, which will affect the driving safety of the vehicle. At present, the test of the safety loop function of the sliding door of the EMU is to monitor the closed state of the doors of all rows through the monitoring screen of the driver's cab. In the event of jamming, it is necessary to mechanically isolate the plug ...
