Internet of Things-based PM2.5 (Particulate Matter2.5) purification system applicable to public infrastructure

Abstract

The invention discloses an Internet of Things-based PM2.5 (Particulate Matter2.5) purification system applicable to a public infrastructure. The Internet of Things-based PM2.5 purification system applicable to the public infrastructure comprises an Internet of Things monitoring center, a communication base station, the public infrastructure and a PM2.5 purification device, wherein the Internet of Things monitoring center is used for monitoring and correspondingly controlling the atmospheric environment around the public infrastructure and operation states of the PM2.5 purification device in long distance; the communication base station is taken as a communication medium between the Internet of Things monitoring center and the PM2.5 purification device; the PM2.5 purification device is capable of generating negative ions in a high-voltage ionization manner and purifying PM2.5 in the atmospheric environment; the opening and closing states of the PM2.5 purification device and the negative ion generation power can be controlled by the Internet of Things monitoring center in long distance. The system is capable of intelligently purifying the PM2.5 in the outdoor atmospheric environment and saving energy.

Description

technical field [0001] The invention relates to an atmospheric environment improvement system based on the Internet of Things, in particular to a PM2.5 purification system applied to public infrastructure. Background technique [0002] With the emergence of large areas of smog in our country, the problem of air pollution, especially the concentration of PM2.5, has become one of the problems that need to be solved and improved in the world. PM2.5 refers to particulate matter with a diameter of 2.5 microns or less. It can be suspended in the air for a long time, and the higher its concentration in the air, the more serious the air pollution. Compared with coarser atmospheric particles, PM2.5 has small particle size, large area, strong activity, easy to attach toxic and harmful substances (such as heavy metals, microorganisms, etc.), and has a long residence time in the atmosphere and a long transportation distance. Therefore, it has a greater impact on human health and atmos...

AI Technical Summary

Problems solved by technology

[0004] Existing PM2.5 purification devices, whether using physical and chemical methods or high-voltage ionization to generate negative ions, are continuously purified. If they want to stop, manual intervention is required on site.

It is impossible to remotely adjust the negative ion generation power of the device itself according to the air quality and to control the start and stop of the purification device, which is a serious waste of manpower and resources
