VOCs (Volatile Organic Compounds) region on-line monitoring and early warning system

Abstract

The invention provides a VOCs (Volatile Organic Compounds) region on-line monitoring and early warning system, which comprises a monitoring module, a communication module, a data storage module, an application service module and a man-machine interaction module, wherein the monitoring module collects monitoring data of each monitoring point; the communication module receives the monitoring data; the data storage module stores the monitoring data; the application service module receives and intelligently analyzes the monitoring data, performs inorganization discharging source strong analysis and contaminant diffusion trend reckoning by combining meteorological parameters and discharging source data, draws a source intensity and contaminant diffusion trend schematic diagram, and builds a contaminant diffusion model; the man-machine interaction module receives an operation command input by a user, displays the monitoring data and warning record of each monitoring point. The system provided by the invention has the advantages that the contaminant diffusion source intensity calculation and the diffusion trend reckoning functions can be realized; in addition, the equivalent source intensity and diffusion trend can be dynamically drawn on a GIS (geographic information system).

Description

technical field [0001] The invention relates to the technical field of pollutant discharge monitoring, in particular to a VOCs regional online monitoring and early warning system. Background technique [0002] In recent years, with the strong support of the central and local governments, the routine monitoring system of air quality has been greatly developed, and the monitoring capacity has been continuously improved. However, compared with this, the early warning and monitoring system of toxic and harmful gases is still in its infancy. Toxic and harmful gases such as chlorine, phosgene, hydrogen sulfide, ammonia, and benzene series that can cause large-scale casualties in a short period of time and pose a serious threat to human health have not been included in the routine air quality monitoring system. Building a toxic and harmful gas early warning system in key areas where risk substances and people gather is an important part of a sound monitoring network and a necessary...
