Description

Technical Field

[0001] This application relates to the field of rail vehicle technology, and in particular to a working circuit and control method for an emergency evacuation device for rail vehicles. Background Technology

[0002] Emergency evacuation devices are equipment equipped on rail vehicles to evacuate passengers and crew in emergency situations. When a situation occurs while the rail vehicle is in motion, it will stop urgently. Because the rail vehicle is far from the ground, after the escape door is opened, an emergency evacuation device needs to be placed below the escape door to escape from the vehicle to the ground in time.

[0003] The existing emergency evacuation device is a retractable emergency evacuation ladder installed under the train floor, specifically in a compartment below the doors. During train operation, vibrations or other unexpected events may cause the emergency evacuation ladder to open, resulting in vehicle equipment encroachment and affecting railway safety. Furthermore, the existing emergency evacuation device's activation control strategy has certain safety hazards; the device is prone to accidental activation. If the emergency evacuation device is accidentally activated while the train is in motion, it will not only affect railway equipment safety and reduce passenger evacuation efficiency, but if the wrong escape door is opened, passengers may fall onto the tracks, increasing the risk of personal injury. Therefore, the control of emergency evacuation devices is crucial. Based on the above reasons, it is necessary to provide a method for controlling emergency evacuation devices to solve the problem of erroneous activation of existing emergency evacuation devices in emergency situations.

[0066] When a side emergency evacuation device is activated:

[0067] (1) Obtain vehicle zero speed signal K from vehicle zero speed signal input terminal 203. The vehicle zero speed response unit 20 responds to the vehicle zero speed signal K and outputs the DC voltage provided by the power supply unit 10 input from the first input terminal 201 to the skirt interaction unit 30 through the first output terminal 202. The skirt unfolding button 301 receives the voltage signal from the first voltage output terminal 311 and turns on, outputting the first voltage 31 to the first signal input terminal 501 of the door enable response unit 50. The first door enable signal input switch 51 selects the first side to turn on and outputs the voltage signal input from the first signal input terminal 501 to the first signal output terminal 5011.

The driver and passengers can escape from the emergency evacuation passage opened on the first side.

[0069] (3) After the escape is over, when the emergency evacuation device is retracted, the ladder retraction button 402 receives the voltage signal from the fourth voltage output terminal 412. The ladder retraction button 402 is turned on and outputs the fourth voltage 42 to the fourth signal input terminal 504 of the door enable response unit 50.

[0071] When the two-position emergency evacuation device is activated:

[0072] 1) Obtain the vehicle zero-speed signal K from the vehicle zero-speed signal input terminal 203. The vehicle zero-speed response unit 20 responds to the vehicle zero-speed signal K by outputting the DC voltage provided by the power supply unit 10 input from the first input terminal 201 to the skirt interaction unit 30 through the first output terminal 202. The skirt unfolding button 301 receives the voltage signal from the first voltage output terminal 311 and turns on, outputting the first voltage 31 to the first signal input terminal 501 of the door enable response unit 50.

[0073] 2) In response to the vehicle's zero-speed signal K, the DC voltage provided by the power supply unit 10 input at the first input terminal 201 is output to the folding ladder extension interaction unit 40 through the first output terminal 202.

The sixth signal output terminal 5032 is connected to the second position side ladder unfolding cylinder solenoid valve 632, driving the second position side folding ladder to extend and open from the ladder outlet, allowing passengers to escape through the emergency evacuation passage opened on the second position side.

[0074] 3) After the escape is over, when the emergency evacuation device is retracted, the ladder retraction button 402 receives a voltage signal from the fourth voltage output terminal 412. The ladder retraction button 402 is turned on and outputs the fourth voltage 42 to the fourth signal input terminal 504 of the door enable response unit 50. The fourth door enable signal input switch 54 selects the second position side to be turned on and outputs the voltage signal input from the fourth signal input terminal 504 to the eighth signal output terminal 5042. The eighth signal output terminal 5042 is connected to the second position side ladder retraction cylinder solenoid valve 642, which drives the second position side folding ladder to retract from the ladder outlet.

[0075] 4) When the skirt panel retraction button 302 receives the voltage signal from the second voltage output terminal 312, the skirt panel retraction button 302 is turned on, and the second voltage 32 is output to the second signal input terminal 502 of the door enable response unit 50.
