Subway safety door self-check method

Abstract

The invention relates to a method for self-inspection of a subway safety door. A self-inspection platform is pre-built, including a laser emitting module, a laser detection module, a laser reflector, a microprocessor, a data sending module and a data receiving module; when the subway safety door is locked, the Before starting, the on-board control system of the subway sends instructions to the processor, so that the subway safety door starts to enter the second self-inspection process; the microprocessor controls the laser emitting module to emit a beam of laser, and the laser detection module starts to detect the laser at the same time, and sends the detection result to to the microprocessor; according to the detection results, it is judged whether there is a foreign object between the subway security doors, and the judgment result is sent to the on-board control system of the subway, so that it can carry out subsequent control actions. The invention is safe and reliable, and can carry out secondary detection on the subway safety door after it is closed. When there are thin objects such as clothes and hair caught on the subway door, they can be detected through the secondary detection, thereby effectively controlling the safety problem of the subway.

Description

technical field [0001] The invention relates to a self-inspection method for a subway safety door, in particular to a secondary self-inspection method after the subway safety door is locked. Background technique [0002] The traditional subway safety door will only be equipped with a safety closing self-checking facility, which has insufficient or no sensing ability for some relatively thin media, such as clothing or hair. When the clothes or hair of subway passengers are caught by the subway doors, the passengers have to wait for the next station to open the door to be rescued. This situation is also likely to cause more serious accidents. [0003] In order to better ensure the personal safety of subway passengers, multiple laser sensing devices can be installed to prevent the subway safety door from trapping people. However, when the subway safety door is completely closed and locked, the current safety measures have basically failed. [0004] In view of this, it is the s...

Problems solved by technology

[0005] In view of the above problems, the object of the present invention is to provide a method for self-inspection of subway safety doors, which aims to solve the problem that the personal safety of passengers is endangered because the current subway safety doors cannot detect thin objects such as clothes and hair that are caught
