Embodiment Construction
[0045] Hereinafter, the present invention will be further described with reference to the drawings and specific implementations:
[0046] Such as Figure 1-2 As shown, the ventilation and air-conditioning control system based on real-time video analysis of the present invention includes a video collector 1 installed in the laboratory, which is connected to the video collector 1 in signal, extracts and analyzes the image signals collected by the video collector, and obtains experiments An image recognition unit 2 for the number of indoor real-time personnel, and a variable wind pressure VAV control unit 3 signally connected to the image recognition unit 2 and working according to the real-time number of personnel in the laboratory recognized by the image recognition unit 2.
[0047] Due to the large exhaust air volume designed in the laboratory, in the environment where the indoor pressure difference needs to be ensured, the new air volume design of the ventilation system is also re...

The invention discloses a ventilation and air-conditioning control system based on real-time video analysis. The ventilation and air-conditioning control system comprises a video collector mounted in a laboratory, an image recognition unit and a variable air volume (VAV) control unit, wherein the image recognition unit is in signal connection with the video collector, and used for extracting and analyzing image signals collected by the video collector to acquire the real-time number of staff in the laboratory; the VAV control unit is connected with the image recognition unit, and works according to the real-time number of staff in the laboratory; and the real-time number of staff in the laboratory is acquired by the image recognition unit through image recognition. According to the ventilation and air-conditioning control system, the work of the VAV control unit is controlled by adopting the image recognition unit, so that the air volume demand of the laboratory and the opening value of a VAV valve can be matched automatically; according to the control target, the frequency of a draft fan and that of an exhaust fan are reduced to the greatest extent, thereby reducing the pressure difference of an air duct; and under the circumstance that the exhaust volume is guaranteed, the throttling effect of the VAV valve is reduced to lower energy consumption, and the running noise of the draft fan, the exhaust fan and the air duct is reduced.
Description
Technical field [0001] The invention relates to a ventilation and air conditioning control system, in particular to a ventilation and air conditioning control system based on real-time video analysis. Background technique [0002] Common laboratories can be divided into biological laboratories, animal laboratories, physics, chemical laboratories, etc. Different laboratories have different requirements for indoor environment control. The design of traditional laboratory ventilation and air-conditioning systems mostly uses constant air volume control, and the ventilation system operates at full load. In the actual operation and use process, the use of laboratory exhaust equipment is very random, and there is less full load operation. Therefore, if the ventilation system is operated at full load, it will cause a lot of waste of energy. [0003] Patent document CN105190191A discloses an "energy-saving heating, ventilation, and air-conditioning control system". The head detection meth...
