[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to Chinese patent application number 2023112878162 filed with the Chinese Patent Office on October 7, 2023, entitled “A working circuit and control method for a rail vehicle emergency evacuation device,” the entire contents of which are incorporated by reference into this application. Technical Field

[0003] The present application relates to the technical field of rail vehicles, and in particular to a working circuit and a control method of an emergency evacuation device for a rail vehicle. Background Art

[0004] The emergency evacuation device is a device equipped on rail vehicles for evacuating vehicle drivers and passengers in emergency situations. When a situation occurs while the rail vehicle is driving, it will stop urgently. Because the rail vehicle is a long distance from the ground, an emergency evacuation device is required under the escape door after the escape door is opened, so that people can escape from the vehicle to the ground in time through the emergency evacuation device.

[0005] The existing emergency evacuation device is a retractable emergency evacuation ladder installed under the train floor, specifically in a storage compartment below the door. During train operation, the emergency evacuation ladder may be opened due to vibration or other accidents, causing vehicle equipment to infringe on the limit and affecting railway safety. In addition, the opening control strategy of the existing emergency evacuation device has certain safety hazards. The device is prone to accidental opening. If the emergency evacuation device is accidentally opened while the train is moving, it will not only affect the safety of railway equipment and reduce the efficiency of passenger evacuation, but if the wrong escape door of the emergency evacuation device is opened, passengers may fall onto the track, increasing the risk of personal injury. This shows the importance of controlling the emergency evacuation device. For the above reasons, it is necessary to provide a method for controlling the emergency evacuation device to solve the problem of the existing emergency evacuation device opening incorrectly in an emergency.
