Regional air pollutant concentration over-limit early warning system

Abstract

The invention provides a regional air pollutant concentration over-limit early warning system, comprising a sensing module and an early warning module, wherein the sensing module is configured to acquire air pollutant concentration data of a to-be-monitored region; the early warning module is configured to analyze the air pollutant concentration data and transmit an early warning signal to a preset user terminal when the air pollutant concentration data exceeds a set threshold value; the sensing module comprises a base station and sensor nodes; a wireless sensor network with a clustering structure is constructed by the base station and the sensor nodes in a self-organization way, wherein when network topology is constructed, cluster heads are elected from the sensor nodes through cluster head election, and clustering is performed according to the elected cluster heads; the cluster head is configured to collect air pollutant concentration data acquired by the sensor nodes within the cluster and transmit the collected data to the base station; and the base station is configured to gather the air pollutant concentration data transmitted by the each cluster head and transmit the gathered data to the early warning module.

Description

technical field [0001] The invention relates to the technical field of air pollution monitoring, in particular to an early warning system for regional air pollutant concentration exceeding the standard. Background technique [0002] In the prior art, the methods for observing the concentration of air pollutants are mainly: [0003] (1) The traditional method, that is, the method of manual sampling laboratory analysis. This method can only obtain the monitoring value within a certain period of time in the air pollution monitoring area, and cannot perform real-time monitoring. The monitoring results are greatly affected by human beings. the physical health of personnel; [0004] (2) The current popular online monitoring mostly uses imported automatic air environment monitoring equipment for monitoring. Although this monitoring method can achieve real-time monitoring, the equipment used is complex in structure, expensive, difficult to maintain, and has high operating costs. ...
