Foreign object detecting system between screen door and train door of subway station platform

Abstract

The invention discloses a foreign object detecting system between a screen door and a train door of a subway station platform. The foreign object detecting system comprising a foreign object detectiondevice and an image processor is characterized in that the foreign object detection device comprises a first detection module which comprises a first lamp belt and a first camera; the first lamp beltand the first camera are disposed between the screen door and the train door of the platform; the first lamp belt is vertically arranged on one end of a to-be-detected platform segment; the first camera is arranged on the other end of the to-be-detected platform segment and faces the first lamp belt; the first camera acquires the image of the first lamp belt to be sent to the image processor; theimage processor is used for identifying the image of the first lamp belt and judging whether a foreign object exists by judging the integrity of the image of the first lamp belt. The foreign object detecting system can detect the foreign objects at the distance between the screen door and the train door of a subway and high-speed railway platform with no blind spots, and eliminating or reducing accidents of clamping people occurring between the screen door and the train door.

Description

technical field [0001] The invention relates to a traffic facility, in particular to a foreign object detection system between a screen door of a subway platform and a train door. Background technique [0002] With the rapid development of science and technology, the process of urban modernization and the acceleration of the pace of urban life, urban intelligent rapid transportation has been accepted by more and more people. While the rapid rail transit between cities and between cities provides convenience for people, it also has potential safety hazards. In recent years, train injuries have occurred from time to time. In order to solve this problem, the installation of subway and high-speed rail screen door facilities is accepted by the society. [0003] In our country, screen door technology has been widely promoted in other domestic subway projects. The screen door is an important piece of equipment in the subway project. It is installed on the edge of the platform. It...

Problems solved by technology

[0004] However, in the above-mentioned traffic platform screen door / safety door safety protection system, an infrared detection mechanism is used to detect whether there is an obstacle in the space between the subway, high-speed rail platform screen door and the vehicle door. The mechanisms are set at different heights and in different straight line sections. Since the infrared detection mechanism detects foreign objects through infrared rays, for multiple sets of infrared detection mechanisms set at different heights, there will be gaps between the infrared detection mechanisms of two adjacent groups. A certain interval, so there will be some blind spots on the screen door. When the object is in the blind area (for example, when the passenger's hand is clamped and just between the upper and lower sets of infrared detection mechanisms), the above-mentioned traffic platform screen door / safety door safety protection The system will not be able to detect foreign objects, and there are still potential safety hazards
