Indoor air quality regulating and controlling system and method based on personnel location detection

Abstract

The invention discloses an indoor air quality regulating and controlling system and method based on personnel location detection. The system comprises a data collection system, a computer system and an indoor environment regulating and controlling system. The data collection system comprises a personnel counter, an infrared array sensor and an air quality sensor module. The indoor environment regulating and controlling system comprises an indoor integrated main ventilation purifying system and a local regional space ventilation purifying system. The indoor integrated main ventilation purifyingsystem performs indoor integrated ventilation purifying according to the total number, transmitted to the computer system, of indoor persons. The local regional space ventilation purifying system determines whether the local regional space ventilation purifying system is started or not according to data which are transmitted to the computer system by the infrared array sensor and the air qualitysensor module. By means of the regulating and controlling system, the concentration of indoor environment pollutants and the running energy consumption can be controlled more reasonably, the whole airquality operation level can be improved, the risks to health of human bodies and the loss of working efficiency are reduced, and building energy saving is facilitated.

Description

technical field [0001] The invention relates to the technical field of air quality monitoring, in particular to an indoor air quality control system and method, in particular to an indoor air quality control system and method based on personnel positioning detection. Background technique [0002] With the development of my country's economy, people's living standards have improved significantly, and people's demand for indoor environment comfort has continued to grow. The over-reliance on air-conditioning has also produced more and more complaints of "air-conditioning disease", and the World Health Organization defines a series of symptoms of people complaining about discomfort symptoms of unknown causes in the building interior as sick building syndrome (sick building syndrome, SBS) . [0003] Indoor environmental quality has an important impact on human health and work efficiency, and providing a healthy and comfortable indoor environment is the fundamental purpose of mod...

Problems solved by technology

[0004] At present, the most widely used method is to use the indoor air purification system to control the indoor environmental quality. This control method is to uniformly purify the air quality of the entire indoor space. However, in the actual use process, the distribution of indoor personnel is often random. Scattering and concentration, so that the air quality purification in the concentrated area is not in place, and the concentration of pollutants exceeds the standard. In order to improve the air quality in the concentrated area, the power of the overall indoor ventilation and purification system has to be increased, so that It not only causes waste of energy, but also brings risks to the health of indoor personnel
