An anti-retrograde automatic safety escalator for shopping malls based on the Internet of Things

Abstract

The invention discloses an anti-retrograde automatic safety escalator for shopping malls based on the Internet of Things, which can realize real-time acquisition of images based on the Internet of Things by photographing retrograde passengers, and extract passengers' behaviors after a series of image processing and analysis. information and face information, and compare it with the retrograde behavior model of passengers of all ages in the database. After the comparison is passed, it is accurately determined that the passenger has retrograde behavior based on facial recognition technology, and the passenger is prompted to stop the retrograde behavior through voice, and the automatic safety door Turn off the sound and light alarm to prevent passengers from further retrograde danger, so as to prevent problems before they happen. Compared with the existing anti-retrograde method, the present invention is more accurate and less error-prone, and the effect of anti-retrograde is remarkable. At the same time, it provides navigation in the shopping mall Function, correctly guide passengers to the right place to take the escalator or elevator, which brings convenience to passengers and reduces the probability of retrograde accidents.

Description

technical field [0001] The invention relates to the technical field of escalators, and more specifically, to an anti-reverse automatic safety escalator for shopping malls based on the Internet of Things. Background technique [0002] The escalator is a combination of a chain conveyor with a special structure and two belt conveyors with a special structure, with a circular motion ladder path, used to go up or down between different floors of the building It is a fixed electric drive equipment that transports passengers obliquely, and a continuous conveying machine that carries people up and down; the escalator is composed of a ladder road (a modified plate conveyor) and handrails on both sides (a deformed belt conveyor). Its main components include steps, traction chains and sprockets, guide rail systems, main transmission systems (including motors, reduction devices, brakes and intermediate transmission links, etc.), drive spindles, ladder road tensioning devices, handrail s...

Problems solved by technology

[0003] With the popularity of escalators in major shopping malls, it brings convenience to customers but also poses great safety hazards. Taihai.com, April 12, according to Xiamen.com, the escalator is slowly descending, but a child is going backwards. Walking up, he fell into the ladder, and his arm was squeezed to pieces. Fortunately, the squeeze time was not too long, and no tendons, nerves, or bones were injured. Recently, after good treatment, Xiaoyuan (pseudonym) was discharged from the hospital; In the Canal store of Tao Supermarket, an old man misjudged the direction of travel of the escalator, and then appeared in retrograde behavior, which caused him to fall and get injured. There are many news about escalator retrograde accidents. Retrograde dangerous behaviors are prone to occur when there is a lack of care, and the physical condition is relatively fragile, and it is very easy to get injured. Even today's young people are mostly "head-down parties", who like to play with mobile phones. Retrograde behavior occurs, and some customers even go retrograde because they cannot find the correct escalator or elevator to save trouble. The traffic in the mall is relatively large, and this potential danger is never allowed to be ignored. At present, the escalators in the mall still lack corresponding measures preventive
