Air pollution monitoring system based on wireless sensor network

Abstract

The invention provides an air pollution monitoring system based on a wireless sensor network. the system comprises the wireless sensor network, air pollution monitoring sub-centers, a remote control terminal and a user terminal, wherein the wireless sensor network is used for monitoring air pollution, acquiring air pollution monitored data and processing and forwarding the dame; each air pollutionmonitoring sub-center is used for performing bidirectional communication with the wireless sensor network, and can receive and analyze the air pollution monitored data sent by the wireless sensor network, and give an alarm signal when the air pollution monitored data exceeds a set normal threshold; the remote control terminal is used for remotely accessing and monitoring the air pollution monitoring sub-centers and receiving the alarm signals sent by the air pollution monitoring sub-centers; and the user terminal is used for receiving the alarm signal sent by each air pollution monitoring sub-center via a mobile phone network. According to the system provided by the invention, the wireless sensor network technology is used for acquiring the air pollution monitored data and analyzing the same.

Description

Technical field [0001] The invention relates to the technical field of air monitoring, in particular to an air pollution monitoring system based on a wireless sensor network. Background technique [0002] Among the related technologies, the methods for monitoring urban air pollution mainly include: [0003] (1) The traditional method, that is, the method of manual sampling laboratory analysis. This method can only obtain the monitoring values ​​within a certain period of time in the monitoring area, and cannot perform real-time monitoring. The monitoring results are greatly affected by humans. At the same time, when the concentration of harmful gases in the monitoring area is high, it will seriously harm the health of the monitoring personnel. ; [0004] (2) At present, the more popular online monitoring uses imported automated atmospheric environment monitoring equipment for monitoring. Although this monitoring method can achieve real-time monitoring, the equipment used is complex...

[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 monitoring area, and cannot carry out real-time monitoring. The monitoring results are greatly affected by human beings. At the same time, when the concentration of harmful gases in the monitoring area is high, it will seriously damage the health of the monitoring personnel. ;

[0004] (2) The currently popular online monitoring mostly uses imported automatic atmospheric 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 high in operating costs. Its working environment is harsh
