Title:
METHOD AND SYSTEM FOR MONITORING FALLING-OFF OF INDUCTION BOARD OF MAGLEV TRAIN
Document Type and Number:
WIPO Patent Application WO/2022/257398
Kind Code:
A1
Abstract:
A method for monitoring the falling-off of an induction board of a maglev train. The method comprises the following steps: S1, determining whether an output current I0 of each levitation controller is greater than a preset current I2; if the output current I0 of a certain levitation controller is greater than the preset current I2, skipping to step S2; and S2, determining whether several levitation controllers that are located at the rear of the same side of the levitation controller, the output current I0 of which is greater than the preset current I2, have output currents I0 that are all greater than the preset current I2; if so, determining that there is an induction board falling-off fault; and if not, returning to step S1. The beneficial effects are as follows: the induction board falling-off fault can be determined simply by monitoring the output current I0 of the levitation controller; the fault detection costs are low, the speed is high, and the detection result is accurate; and no additional test sensor is required, and the method can be implemented only on the basis of an existing train control network system for a vehicle.
