Air quality monitoring system based on multi-dimensional sensor technology

Abstract

The invention discloses an air quality monitoring system based on a multi-dimensional sensor technology, and belongs to the field of air quality monitoring. The system obtains concentration values ofdifferent gas detection sensors of the same gas compound through a sampling unit, and removes messy and disordered detection quantification values through a signal processing unit and a data processing unit, and thus precision, accuracy and stability of the monitoring data are improved. Detection quantification values of the different gas detection sensors of each gas compound are subjected to normalization weighted average processing so that the detection quantification values of the different gas detection sensors of each gas compound are subjected to analogy and correction, and the obtainedcorrection value of each gas compound has persuasion and accuracy, and thus the problems of poor stability and poor accuracy of a monitoring result caused by using a single sensor are avoided, the difference between the monitoring result and a traditional large-scale air quality monitoring ground station is relatively small, and the requirement of fine management of air quality is met.

Description

technical field [0001] The invention relates to the field of air quality monitoring, in particular to an air quality monitoring system based on multi-dimensional sensor technology. Background technique [0002] With the deteriorating environment, people are more and more concerned about air quality. Therefore, the environmental protection department monitors the concentration of various gas compounds in the local atmosphere by establishing air quality micro-stations in various places, and realizes real-time monitoring through Internet connection. The concentration of various gas compounds in the atmospheric environment. [0003] Existing air quality micro-stations use a single sensor method, such as small molecular gas compounds using electrochemical sensors, because of their principles and factors affected by the environment, the accuracy, accuracy and stability of the monitoring results are comparable to traditional large-scale air quality monitoring ground At the same ti...
