Automatic air monitoring system and monitoring method thereof

Abstract

The invention provides an automatic air monitoring system and a monitoring method thereof. The automatic air monitoring system comprises a sample monitoring unit, a data transmission unit and a central processing unit. The system adopting scientific structural design greatly improves automation, instantaneity and accuracy of air monitoring in dependence on the structural design and a scientific monitoring method in an optimized monitoring means under the condition that energy consumption is not increased and no special equipment is additionally arranged; damage of fan blades to an initial value of sampled air in a fan blast sampling device in the prior art is well eliminated with the adoption of the pure physical structural design of the Venturi effect; the objectivity and the authenticity in the air monitoring process are well realized through the structural design of multiple monitoring air channels; the system adopts a wireless PC card communication technique and supports a GPRS (general packet radio service) wireless data transmission technique, and promptness of air monitoring is greatly improved.

Description

technical field [0001] The invention relates to the technical field of gas monitoring systems, in particular to an automatic gas monitoring system and a monitoring method thereof. Background technique [0002] Atmospheric pollutants are divided into two categories: particulate pollutants and molecular pollutants (also known as gaseous pollutants) according to their state of existence; according to the state of existence of pollutants, air pollution monitoring items are also divided into particle pollutant monitoring and gaseous pollutant Monitoring of two major monitoring items; Among them, the monitoring of particulate pollutants is divided into monitoring of total suspended particles, floating dust monitoring, dustfall monitoring and monitoring of particulate pollutant components; monitoring of gaseous pollutants includes: sulfur dioxide, nitrogen oxides, carbon-oxide, photochemical oxidants ( O3), hydrogen chloride, hydrogen fluoride, total hydrocarbons, etc.; in short, t...

Problems solved by technology

[0004] In the existing technology, the system for monitoring the atmosphere generally adopts a fan-shaped layout of sampling points, and the data collected by each decentralized subsystem is summarized to the central control unit for reading, analysis and historical records. This method greatly improves the quality of atmospheric monitoring. The timeliness of environmental monitoring has greatly developed and promoted the monitoring of environmental conditions. However, with the gradual progress of human society, the diversification of various pollution sources, the complexity of the monitoring environment, and the defects in the design of existing gas monitoring equipment have all led to Inaccuracy of Atmospheric Monitoring Data
