Abstract

The invention relates to a multifunctional intelligent air quality detection system with adjustable resolution ratio and a detection method. The system is equipped with one or more air quality detection device distributed in a monitoring area in the form of one main node or one main node and one or more secondary node; each air quality detection device is equipped with a photosensitive sensing unit, a light source unit and an outer shell; the light source unit and the photosensitive sensing unit are respectively connected with the two sides of the end part of the outer shell in the manner of adjustable light beam length through the threads; the outer shell has a cylindrical structure; an air inlet is formed on the outer shell. A large-diameter lens is adopted by the invention, so that air intake volume in the light beam scope can be increased; the detection sensitivity of the device can be increased; the length of the light beam can be changed by changing the length of a ruler, so that the resolution ratio of the device can be changed; data can be conveniently uploaded; the traditional single point test is replaced; the detection result is more true and valid; the scope of the monitoring area is widened.

Description

technical field

[0001] The invention relates to an air quality intelligent detection technology, in particular to a resolution-adjustable multifunctional intelligent air quality detection system and detection method. Background technique

[0002] Atmospheric pollution is the entry of certain substances into the atmosphere due to human activities or natural processes, presents in sufficient concentrations for sufficient time, and thereby endangers the comfort, health and welfare of humans or the environment. Modern industrial production has made air pollution more and more serious. Once pollutants enter the atmosphere, they will be diluted and diffused. The stronger the wind, the stronger the atmospheric turbulence and the more unstable the atmosphere, the faster the dilution and diffusion of pollutants; otherwise, the slower the dilution and diffusion of pollutants. In the latter case, especially when there is a temperature inversion layer, pollutants can often accumulate t...

Embodiment Construction

[0046] like figure 1 As shown, the present invention is a multi-functional intelligent air quality detection system with adjustable resolution, which has one or more air quality detection devices, which are distributed in the form of a master node or a master node and one or more slave nodes to monitor In the area, the air quality detection device as the main node can be used alone; the air quality detection device as the secondary node realizes data communication with the main node through an ad hoc network, and each air quality detection device has a light source unit 1 and a housing 2 And the photosensitive sensor unit 3, wherein, the light source unit 1 and the photosensitive sensor unit 3 are respectively connected to both sides of the end of the shell 2 in a manner that can adjust the length of the light column through a screw; the shell 2 is a cylindrical structure, and an air inlet is provided on it 202.

[0047] In this embodiment, the air inlet 202 is a notch formed...
