Two-dimensional code based metro shield door safety system

Abstract

The invention discloses a two-dimensional code based metro shield door safety system. The system includes image collection devices (1) arranged on one ends of platforms and located between a train andmetro shield doors, an image contrast device (2), a platform control device (3) and a memory (4) which are arranged in a platform control room, display devices (5) arranged in the platform control room and / or on the platforms, luminescent plates (6) arranged on the other ends of the platforms, and two-dimensional codes (7) arranged on the luminescent plates (6). The safety system can completely cover the gaps between the train and the metro shield doors, and can timely find foreign matters in the gaps and send alarm signals; and the system realizes the positioning and grading of faults by introducing a rail transit fault monitoring and intelligent early warning system, so that the safety circuit of the shield doors can be timely cut off to prevent the closing of the shield doors and the running of the train, and therefore, the safety of personnel and the normal running of the train can be maximumly guaranteed.

Description

technical field [0001] The invention relates to the field of rail transit safety, in particular to a safety system for subway screen doors based on two-dimensional codes. Background technique [0002] With the increasing population of big cities, road traffic is increasingly unable to meet the rapidly increasing traffic usage of people. The development of urban rail transit plays an important role in alleviating urban traffic congestion. Since the first subway was built in London in 1863, the subway, as an important means of urban rail transit, has been widely used in developed countries such as Europe and the United States, as well as domestic Beijing, Shanghai, Guangzhou, Shenzhen and other developed areas. [0003] Urban rail transit is a special service industry. In addition to the personal safety of employees, it also includes the personal safety of passengers and the operation safety of various equipment and facilities in the production process. At the same time, there...

AI Technical Summary

Problems solved by technology

[0006] The present invention aims to overcome the problem of blind spots or misjudgments caused by human factors in the detection of foreign objects in the gap between the platform and the train in the prior art, and provides a security system for subway screen doors based on two-dimensional codes, which can fully cover trains and trains. The gap between the screen doors of the subway, and can detect foreign objects in the gap in time and send an alarm signal. The system realizes fault location and rating by connecting to the rail transit fault monitoring and intelligent early warning system, and can cut off the safety The circuit prevents the closing of the screen door and the operation of the train, which can ensure the safety of personnel and the normal operation of the train to the greatest extent.
