Problems solved by technology

[0006] For multi-elevator systems, when there are fewer people, people often press all the elevator buttons on the floor at the same time, but the real need is only 1-2 elevators, and the operation of other elevators is a waste of electric energy

Embodiment Construction

[0018] The present invention is described in detail below in conjunction with accompanying drawing:

[0019] figure 1 It is a schematic diagram of the vision-based intelligent multi-elevator system of the present invention. Such as figure 1 As shown, suppose it is a three-story building with three elevators on each floor, a camera on each floor, and a camera on each elevator.

[0020] The invention includes two parts: the detection of the number of passengers and the optimal scheduling of elevators.

[0021] The number of passengers is detected by the camera and the elevator people counting module of the elevator control system. The cameras inside and outside the elevator are used to obtain image information, and the head detection method based on random Hough transform is used to detect the number of people in the elevator and waiting for the elevator. First, binarize the image to obtain the human area; second, perform edge extraction based on the Canny operator on the ima...

Abstract

The invention discloses an intelligent multiple-elevator system based on vision. The system comprises N elevators and elevator control systems, wherein, N is more than or equal to 2, and are characterized in that cameras are respectively arranged in the elevators and each floor; each camera is connected with the elevator control system; the elevator control system is provided with an elevator people counting module which is used for counting the number of people waiting for the elevator on each floor and the number of people in the elevator, and an elevator people control module which is used for controlling the stop of the elevator according to the number of people waiting for the elevator on each floor and the number of people in the elevator counted by the elevator people counting module. The multiple intelligent elevator systems provided by the invention are suitable for multiple elevator systems, and have the characteristics of low cost, and good energy-saving and emission-reducing effects.

Description

technical field [0001] The invention relates to an intelligent multi-elevator system and a control method thereof, in particular to an energy-saving multi-elevator system, which belongs to the technical field of elevator control. Background technique [0002] Energy conservation and emission reduction is an important national policy to practice scientific development, develop circular economy, build a conservation-oriented and environment-friendly society, and realize the healthy, stable and sustainable development of my country's national economy. Building energy consumption has reached about 1 / 3 of my country's total energy consumption. In large public buildings, the electricity consumption of elevators accounts for more than 17% to 25% of the total electricity consumption, and it is an out-and-out "big energy consumer". How to adopt energy-saving technology to reduce the energy consumption of elevators has become a hot spot in the market. Therefore, doing a good job in ...
