Title:
HIGH-VOLTAGE POWER SUPPLY CONVERSION SYSTEM AND METHOD FOR URBAN RAIL VEHICLES
Document Type and Number:
WIPO Patent Application WO/2021/139390
Kind Code:
A1
Abstract:
A high-voltage power supply conversion system and method for urban rail vehicles: setting in advance a conversion policy used for selecting a high-voltage device for an urban rail vehicle on the basis of the device state of a plurality of high-voltage devices corresponding to the urban rail vehicle; detecting the actual device state of the plurality of high-voltage devices and, on the basis of the conversion policy, selecting a target high-voltage device for the urban rail vehicle; and autonomously controlling a power source terminal of the urban rail vehicle to connect to the target high-voltage device. The present high-voltage power supply conversion system and method for urban rail vehicles can automatically implement high-voltage power source conversion, thereby reducing the workload of the operator and avoiding the safety risk to the vehicle and people caused by improper operation by the operator.
