Multi-elevator parallel operation coordination control method and system based on machine vision

Abstract

The invention discloses a multi-elevator parallel operation coordination control method and system based on machine vision. The multi-elevator parallel operation coordination control method includes the following steps of converting images acquired by cameras inside and outside elevators to grey-scale images and performing binarization processing; performing HOG feature extraction to obtain human body characteristic samples, constructing a type-2 fuzzy neural classifier, performing Binary judgment by means of the trained type-2 fuzzy neural classifier, counting and adding the human body characteristic samples judged by the classifier to obtain the number of people inside and outside the elevators; and scheduling the elevators by means of a coordination control algorithm through the statistics of the number of people inside and outside the elevators, and the comprehensive considering of the number of people waiting for the elevators of each floor, the residual capacity in each elevator, and distance from elevator waiting positions. The multi-elevator parallel operation coordination control method and system effectively reduce the unnecessary elevating of the elevators, reduce the wearing of the elevators, prolong the service life of the elevators, reduce the waiting time for elevator passengers, and make people's life convenient on the basis of energy saving.

Description

technical field [0001] The invention relates to a machine vision-based coordinated control method and system for parallel operation of multiple elevators. Background technique [0002] With the development of cities, people's requirements for living standards continue to improve, and the intelligence of buildings is becoming more and more important. Whether in a residential area or an office building, elevators have become one of the indispensable means of transportation. [0003] And as the density of people increases, in order to facilitate people to take the elevator in time and quickly, there will be multiple elevators running in parallel in the building. When people are waiting for an elevator, they often press several parallel elevators at the same time in order to save time, so that they can receive instructions together, which elevator comes faster and takes which elevator. But this way, while being convenient for some people, has also lengthened the waiting time o...

Problems solved by technology

However, because the video images inside and outside the elevator are often of low definition and are easily affected by interference factors such as light

In this case, the conventional method of counting people based on video images is often not accurate enough
