Problems solved by technology

This is a sensing device that detects whether there is "a foreign object blocking the light curtain" between the train door and the platform screen door. Form a light curtain barrier", which makes the on-site installation more complicated; on the other hand, the biggest disadvantage of using infrared detectors is that it is impossible to identify and distinguish the shape and type of trapped foreign objects

Embodiment

[0050] The concrete result of embodiment is as follows:

[0051] ①Before the train enters the station, the screen door is closed, and the system accurately identifies that there is no foreign object between the screen door and the track, so it notifies the rear that the train can enter the station;

[0052] ②After the train enters the station and comes to a complete stop, open the door first and then the screen door. After the passengers get off / board, the system will accurately identify that there is no foreign object between the screen door and the train. Therefore, close the screen door first and then the car door. stand;

[0053] ③Before the train enters the station, the screen door is closed, and the system accurately recognizes that there is a foreign object between the screen door and the track, and immediately sends an emergency control command to manually remove the foreign object, and at the same time informs the rear that the train cannot enter the station temporari...

Abstract

An intelligent control system for platform screen doors is provided, which belongs to the field of automatic control technology and comprises a CMOS camera, a signal processor, a controller, and a driver. The CMOS camera collects and outputs images to the signal processor. The signal processor is used for the A / D conversion, enchantment processing and information recognition of the images, and converts the recognition results to a control command and outputs the command to the controller. The controller converts the digital control command and emergency control command to an analog control signal and outputs the analog control signal to the driver. The driver drives a mechanical servomechanism after amplification of the analog control signal, thereby controlling the opening / closing operation of the screen door. The inventive system has simple structure and high operational reliability, and can ensure the comfortable travel for passengers and safe and on-time operation of the train.

Description

technical field [0001] The invention relates to a system in the technical field of automatic control, in particular to an intelligent control system for platform screen doors. Background technique [0002] With the rapid development of my country's urban subway and light rail transportation, cities such as Shenzhen and Shanghai have successively installed screen doors on existing subway or light rail platforms in order to improve the riding environment. There is no doubt that installing screen doors on subway or light rail platforms can achieve energy-saving effects on the platform environment control system and provide passengers with a safe and comfortable riding / waiting environment. However, the platform screen door directly faces passengers and is the only channel for passengers to get on and off the train. Its operation mode and reliability are directly related to the quality of service provided by the station to passengers, and are directly related to the convenience a...
