Problems solved by technology

However, mass spectrometers cannot distinguish pollutants with the same relative molecular mass in principle, and the cost is high
In addition, the existing traceability method compares the VOCs spectrum with the existing official spectrums in the fingerprint database for the current or historical navigation monitoring results, and calculates the similarity of the spectrums; however, the meteorological data at different times There are differences, only relying on the comparison of spectra, it is difficult to accurately trace the source

Abstract

The present invention relates to a VOCs pollutant traceability method, terminal and system based on navigation monitoring. The method includes: S1. Carry out navigation monitoring according to a preset navigation route in the area to be monitored, and collect the coordinates of navigation location points and the corresponding Infrared spectrum and meteorological information of the ambient atmosphere; S2. Match the infrared spectrum with the pollutant standard information database to obtain the type and concentration of the target pollutant; the pollutant standard information database stores the pollutant type and infrared spectrum in the area to be monitored S3, determine whether the concentration of the target pollutant exceeds the preset concentration threshold; Meteorological information determines the source area of ​​the excessive pollutants; S5. Determine the suspected polluting enterprises according to the source area of ​​the excessive pollutants and the distribution information of polluting enterprises in the area to be monitored. The traceability precision of the present invention is high.

Description

technical field [0001] The invention belongs to the technical field of pollution discharge monitoring, and in particular relates to a VOCs pollutant traceability method, terminal and system based on navigation monitoring. Background technique [0002] Volatile organic compounds (VOCs) come from a wide range of sources and have complex compositions, which pose a potential threat to human health. The emission process of VOCs pollutants is instantaneous and difficult to control and monitor. [0003] Accurate measurement and precise traceability of VOCs pollutants are the prerequisites for VOCs emission reduction work. Compared with traditional offline monitoring and online monitoring, navigation monitoring technology has the characteristics of large monitoring range, fast response and strong mobility. In recent years, the navigation monitoring technology for VOCs pollutants has received widespread attention. It simultaneously monitors the concentration and composition of VOCs...
