Subway vehicle door emergency unlocking electromagnet control method

Abstract

The invention designs a subway vehicle door emergency unlocking electromagnet control method, and provides a novel vehicle door emergency unlocking control method which combines vehicle door enabling, vehicle zero speed and parking control signals to participate in control for emergency unlocking devices of three gears of initial, request and unlocking. The technical problems of influence on subway vehicle operation caused by vehicle parking due to the fact that passengers operate an emergency handle, or the right of emergency escape of the passengers under the condition that a driver is disabled after emergency parking, or the prolonging of the service life of an emergency unlocking electromagnet are solved, the service life of a whole vehicle electromagnet driving device is prolonged, the emergency unlocking process of a metro vehicle is safer and more controllable, and the influence on normal operation vehicles is reduced.

Description

technical field [0001] The invention relates to a control technology for emergency unlocking of a subway vehicle door, and more specifically, to a control method for an emergency unlocking electromagnet of a subway vehicle door. Background technique [0002] The passenger compartment of existing subway vehicle is all equipped with car door emergency unlocking device, and the subway car door emergency unlocking device is under abnormal circumstances, such as when the subway car door cannot be opened or when an emergency is encountered, the device for artificially opening the subway car door. The unlocking device is generally an emergency unlocking handle, and generally sets three gears of "initial-request-unlock". Generally, when the vehicle is at a non-zero speed, the unlocking handle is limited by the electromagnet control and can only be operated to the "request" position. When the vehicle is at zero speed, the electromagnet control release can be operated to the "unlock" ...

AI Technical Summary

Problems solved by technology

This method relies on the signal control system must have the function of automatically controlling the vehicle according to the unlock request signal. Generally, the signal system only has the above function in fully automatic driving vehicles, which has certain limitations.

And once someone operates the unlock handle, it will eventually cause the vehicle to stop. If it stops between two stations, it will have a great impact on the line operation
