Big data-based air purification system

Abstract

The invention discloses a big data-based air purification system. Sensor nodes are connected with a main controller through a Zigebee module and by an ad-hoc networking mode to form an effective internal network for acquiring air quality data within a monitoring range, door and window opening and closing state data within the monitoring range and personnel activity data within the monitoring rangeas well as transmitting the acquired data to the main controller through the internal network and in a wireless mode; the main controller receives and completes processing and analysis of the data aswell as outputs a corresponding control command to each control terminal based on the result of processing and analysis to realize modification of the working states of an unmanned aerial vehicle, anair purifier and a mobile phone app; and the unmanned aerial vehicle is used for spraying an air purifying agent. The big data-based air purification system can independently realize acquisition of environmental parameters in the monitoring range, can realize automatic generation of a purification scheme based on a neural network model and the nearest neighbor classifier, and has high automationdegree.

Description

technical field [0001] The invention relates to the field of air purification, in particular to an air purification system based on big data. Background technique [0002] With the development of economy and society and the improvement of people's living standards, the public's requirements for environmental protection and health are also constantly increasing. Air pollution in closed and semi-closed spaces (including indoor space, underground space, and air pollution in cars) is a Invisible air pollution has caused a non-negligible impact on human health, so it has received more and more attention. In closed and semi-enclosed spaces, the release of air pollution pollutants is characterized by persistence and uncertainty. The main pollutants include formaldehyde, bacteria, viruses, dust mites, particles, pollen, etc. Evidence shows that these pollution The harm of pollutants to the human body is much higher than the harm of air pollution to the human body. Indoor pollutant...

AI Technical Summary

Problems solved by technology

In the prior art, the air purifier mainly adopts the method of human control, which has a certain hysteresis, and the purification mode is also selected manually, and the degree of intelligence is low.
