Central air-conditioner control method based on video people counting statistic analysis

Abstract

The invention discloses a central air-conditioner control method based on video people counting statistic analysis. The central air-conditioner control method includes discontinuously acquiring video streaming data in a monitored area and transmitting the video streaming data to a server; using the server to analyze each frame of images in the video streaming data in the same time period so as to count people; dividing the monitored area into a plurality of sub-areas; estimating the number of people in each sub-area, and averaging the number of people in continuous N frames of images in the same time period in the video streaming data to obtain distribution conditions of the number of people in the same time period in each sub-area; generating a control signal according to the distribution conditions of the number of people so as to control central air-conditioners in the sub-areas. Compared with control methods in the prior art, the central air-conditioner control method has the advantages that purposes of intelligently controlling on-off, air-out volume and air-out directions of the central air-conditioners according to the distribution conditions of the number of people are achieved, so that efficiency of the central air-conditioners is maximized, and energy waste is effectively reduced.

Description

technical field [0001] The invention relates to the technical field of central air-conditioning energy-saving control, and more particularly relates to a central air-conditioning control method and a control system based on video population statistics analysis. Background technique [0002] With the rapid development of the economy, the demand for energy has also increased significantly. With the continuous popularization of the concept of intelligent building and energy saving and emission reduction, while the central air conditioner creates a comfortable indoor environment for people, its huge energy consumption has also attracted great attention. How to reduce the energy consumption of central air-conditioning has become an indispensable link in energy conservation and emission reduction and green city construction. [0003] At present, most central air conditioners are switched on and off in a unified way, and the intensity is adjusted uniformly and the direction of the...

Problems solved by technology

[0003] At present, most central air conditioners are switched on and off uniformly, and the intensity is adjusted uniformly and the direction of the air is controlled. The following problems are common: one is that the air conditioner is not turned off when people walk or there are few people but the air output of the air conditioner is large, resulting in a lot of waste of energy consumption; The second is that the air conditioner cannot distinguish between areas with many people and areas with few people. The air volume in each area and in all directions is the same, so that there is no difference in the air volume of the air conditioner in areas where people gather and sparsely populated, resulting in the failure of the central air conditioner to exert its maximum efficiency; the third is The air conditioner cannot automatically adjust the air outlet direction according to the distribution of the number of people, it needs to be adjusted manually, which causes inconvenience
