Internet of Things-based anti-retrograding safety escalator used for shopping malls

Abstract

The invention discloses an Internet of Things-based anti-retrograding safety escalator used for shopping malls. On the basis of Internet of Things, an image is acquired in real time by shooting a retrograding passenger; behavior information and face information of the passenger are extracted after a series of image processing and analysis, and are compared with a retrograding behavior model for passengers of all ages in a database; after comparison passes, the passenger having a retrograding behavior is accurately judged based on a facial recognition technology, and the passenger is prompted through voice to stop the retrograding behavior; and meanwhile, an automatic safety door is closed and an audible and visual alarm is started to prevent the situation that the passenger retrogrades further to be in danger, and taking preventive measures is achieved. Compared with an existing anti-retrograding way, the anti-retrograding safety escalator is more accurate and is not easy to make mistakes, and has a notable anti-retrograding effect; and meanwhile, a navigation function in a shopping mall is provided to correctly guide passengers to go to a suitable site to take an escalator or an elevator, and the probability of the retrograding accident is lowered while convenience is brought to the passengers.

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
