Problems solved by technology

Therefore, this principle sensor has the disadvantage that the detection resolution cannot meet the requirements of air quality monitoring. At present, the low-concentration end data displayed by the instrument device manufactured with this sensor is calculated based on mid-to-high-end data and cannot represent real data.
At the same time, because the electrochemical sensor itself has the characteristics of mutual interference between gases, there will be a large systematic error in the data obtained without the help of hardware design and software reasonable algorithms.

Abstract

The invention discloses a method and a system for monitoring and analyzing air. The method comprises the following steps: collecting gas at the site, and carrying out pressurization on the on-site gas, wherein, the pressure applied on the on-site gas is equal to or less than a preset pressure threshold; heating up the pressurized gas to a preset temperature threshold; detecting the heated gas by using a sensor group to obtain parameters of various gasses in the heat gas and generate multi-channel detection signals of the parameters of the various gasses; analyzing the multi-channel detection signals to obtain the gas status of the on-site gas. The invention further discloses a system for monitoring and analyzing air. According to the invention, signal stability and resolution are effectively raised, the lowest checked out thresholds of the whole system is reduced by an order of magnitude, and the technical requirements of air quality monitoring are completely satisfied.

Description

technical field [0001] The invention relates to the technical field of environmental monitoring, in particular to an air monitoring and analysis method and system. Background technique [0002] Traditional instruments and devices used in environmental monitoring include the following situations: [0003] (1) An environmental monitoring system consisting of one or more single gas analyzers. The system has the advantages that the monitoring parameters can be increased or decreased, and the monitoring accuracy is high, stable and reliable. [0004] However, the system has the disadvantages of large volume, high power consumption, and inability to move. At the same time, the high cost of the system and the high maintenance cost make the system only suitable for monitoring in key areas of large cities, which is not conducive to promotion. [0005] (2) A regional environmental monitoring method consisting of a group of monitoring systems and multiple gas samplers or particle sam...
