Atmospheric haze detection device based on Internet of things

Abstract

The invention discloses an atmospheric haze detection device based on the Internet of things and belongs to the field of haze detection. According to the atmospheric haze detection device based on theInternet of things, firstly, under the action of a plurality of air suction channels with the same length in different directions, a deviation of a detection result caused by one-way sampling is effectively avoided; secondly, a pneumatic net is arranged, after each sampling is finished, a gas can be controlled to be introduced into the device so that an air support deformation wire is expanded; at the moment, an external fixed multi-ball rod is not in contact with the air support deformation wire; and then, air bleeding is controlled so that the air support deformation wire is shrunk and restored to an original shape. Therefore, in an outer portion of a multi-bulging point wrapping the outer fixed multi-ball rod, by continuously repeating the process, dust in the air adhered to the outersurface of the air support deformation wire can be effectively loosened so that a situation that an air detection result is influenced by residual air impurities on the air support deformation wire iseffectively avoided, and accuracy of an atmospheric haze detection result is remarkably improved.

Description

technical field [0001] The invention relates to the field of haze detection, and more specifically, to an atmospheric haze detection device based on the Internet of Things. Background technique [0002] Smog, as the name suggests, is fog and haze. But the difference between fog and haze is very big. The aerosol system composed of dust, sulfuric acid, nitric acid and other particles in the air causes visual impairment called haze. Haze is exactly smog (smog), and particles such as dust, sulfuric acid, nitric acid, organic hydrocarbons in the air can also make the atmosphere cloudy. [0003] Fog is an aerosol system composed of a large number of tiny water droplets or ice crystals suspended in the air near the surface. It mostly occurs in autumn and winter, and is the product of condensation (or sublimation) of water vapor in the air near the surface. The existence of fog will reduce the transparency of the air and deteriorate the visibility. If the horizontal visibility o...

Problems solved by technology

[0005] In the prior art, when detecting atmospheric haze, the equipment used usually only samples in one direction for the atmospheric absorption sampling at the same place. Due to the fluidity of the atmosphere, there are certain differences in the atmosphere, which leads to the detection results There is a certain error. At the same time, due to the smog atmosphere, there are some impurities such as colloidal particles and dust, which will adhere to the filter at the end of the inhalation channel when absorbing and sampling. The repeated sampling results have a certain impact, resulting in certain errors in the test results, and the accuracy is not high.
