Platform screen door safety protection control method and system

Abstract

The invention relates to a platform screen door safety protection control method and a platform screen door safety protection control system. The platform screen door safety protection control method comprises the steps that: a platform screen door PEDC receives a door opening signal from a signal system on a train and sends the door opening signal to a monitoring unit so as to make the monitoring unit operate; the monitoring unit shoots an image signal of a gap between the platform screen door and the train, and respectively sends the image signal to a storage module and an image analysis module in a host; and the platform screen door PEDC sends a platform screen door locking signal to the monitoring unit when detecting that the platform screen door is closed and locked, so that the image analysis module judges whether an obstacle exists in the gap between the platform screen door and the train according to the image signal, if so, sends an alarm signal to an audible and visual alarm and a display, and if not, sends a safety signal to the platform screen door PEDC. The platform screen door safety protection control method and the platform screen door safety protection control system are used for monitoring the gap between the platform screen door and the train in real time through the monitoring unit, are suitable for both curve and straight line station platforms, and have high detection accuracy and fast response speed.

Description

technical field [0001] The invention relates to the technical field of screen door control, in particular to a safety protection control method and system for a screen door. Background technique [0002] In recent years, with the continuous and rapid development of the rail transit industry, it has become the main means of transportation for people to travel, the passenger flow has continued to increase, and the line network has become increasingly complex. In order to ensure the safety of passengers on board, to prevent accidents on board under the situation of a large number of crowded passengers, a screen door is mostly set between the current subway platform and the train. There is a distance of 10-15 cm between the screen door of the straight platform and the subway train, and the gap between the screen door of the curved platform and the subway train exceeds 20 cm, and it is impossible to rely on the train driver to directly observe the distance between the screen door...

Problems solved by technology

However, the laser of this product needs to be parallel to the train. For the curved platform, multiple sets of equipment need to be installed, and the detection range is narrow. Multiple lasers need to be installed, which is greatly affected by the external environment. When a fault occurs, the entire side of the platform cannot be put into detection and cannot be accurate Locating Screen Doors with Barriers
