Fresh air system and fresh air control method based on 5G network and human flow recognition

Abstract

The invention relates to the technical field of image processing and fresh air control, and particularly discloses a fresh air system and a fresh air control method based on 5G network and human flowrecognition. The fresh air system comprises a frequency conversion fresh air ventilator, a plurality of human flow data obtaining facilities arranged in various stores for obtaining human flow data, data transmission equipment used for transmitting signals of the human flow data obtaining facilities to a computer, an electric control valve arranged at the fresh air pipeline inlet position and usedfor controlling the fresh air volume, the computer for controlling air conditioner tail ends, a DDC of a fresh air valve and corresponding lines, storage equipment for storing computer data and the multiple air conditioner tail ends capable of being applied to an air conditioner system. According to the scheme, large-scale carbon dioxide sensor installation in a commercial complex is avoided, thecost and the manufacturing cost are reduced, in the angle of the business side, unnecessary complaints and turnover reduction caused by exposure of carbon dioxide concentration are avoided, and multiple commercial complex factors are considered.

Description

technical field [0001] The invention relates to the technical fields of image processing and fresh air control. Background technique [0002] In existing commercial complexes, the energy consumption of air conditioners accounts for a large part of the total energy consumption. However, the thermal comfort in many commercial complex buildings still cannot meet the demand. One important reason is that the actual number of people in commercial complexes will be high. The number of people in the design is limited, and when the density of people in a closed environment is too high, a high concentration of carbon dioxide will be generated. If there is not enough fresh air to dilute and discharge carbon dioxide, it will cause the human body to feel dizzy, palpitations and other discomforts. The demand for the fresh air volume of the fresh air system during operation is much higher than the design value. At the same time, during non-peak hours, due to the lack of personnel, if the ...

Problems solved by technology

The technology in this patent recognizes the flow of people only when there are people at the boarding gate and takes pictures of them. It is suitable for areas where people are stable and does not move, and the ability to change in real time is weak. places with high crowd flow

[0009] However, in "CN201811176929 An Intelligent Control System and Method for Passenger Room Ventilation of Rail Transit Vehicles", the adjustment of the ventilation volume of this patent can only be adjusted according to the number of personnel, and there is no way to do it according to the real needs of the actual number of people. volume, matching the fresh air volume with the number of people

[0010] Some other patents use carbon dioxide concentration as an indicator to estimate the number of people in the room. Contrary to the purpose of this patent, if carbon dioxide concentration is used as an indicator, the carbon dioxide concentration can only reflect the air carbon dioxide concentration in a part of the area, and cannot Estimate the overall number of people in the room of the store
