Escape door unlocking control device of unmanned subway train

Abstract

The invention discloses an escape door unlocking control device of an unmanned subway train. The device comprises an escape door request switch, an escape door switch trigger relay, an ATC release electromagnet, an ATC release relay, an electromagnet for limiting a spring bolt of an unlocking handle and first and second release circuits connected with the electromagnet in series. A first normallyclosed contact of the escape door request switch is connected into the first release circuit in series, a normally open contact of the ATC release relay is connected into the second release circuit inseries, a normally open contact of the escape door request switch and the escape door switch trigger relay are connected into a train circuit in series, and a normally closed contact of the ATC release electromagnet and the ATC release relay are connected into the train circuit in series. The risk caused since passengers are free to open an escape door in the train running process of a full-automatic driving vehicle with no driver on duty is avoided, The escape door unlocking control device can be popularized to full-automatic unmanned train escape door control according to specific scene application requirements, and can safely and reliably operate the cab escape door.

Description

Technical field [0001] The invention relates to the technical field of unlocking control of escape doors of fully automatic unmanned subway vehicles. Background technique [0002] In traditional manned subway vehicles, the escape door is opened by pure mechanical operation. When opening the door, you only need to operate the unlocking handle clockwise to operate. The driver is solely responsible for opening or closing the escape door. Passengers who are not on duty are not considered for self-escape. Risk issues. Fully automatic unmanned driving has only been used in China in recent years. Starting from the needs of application, the escape door unlocking control logic is added, so that passengers can safely and reliably operate the escape door of the cab. [0003] The existing driver's cab escape door unlocking device is a purely mechanical structure, with a locking bolt on the door side and a bolt lock hole on the door frame, and the two cooperate with each other to ensure that t...

AI Technical Summary

Problems solved by technology

[0004] If the fully automatic unmanned subway only opens the door through purely mechanical operation, when there is no driver on duty (the locomotive is electrified), passengers in an emergency open the escape door at will, and the passengers fall into the track without anyone knowing, which poses a safety hazard. It is not conducive to the escape of passengers, so it is necessary to set the escape door unlocking control logic for fully automatic driverless trains
