Embodiment

[0040] An air pollution monitoring system based on a wireless sensor network, comprising a wireless sensor network node, a wireless sensor network convergence node, a local monitoring sub-center, a remote control terminal, and a mobile phone terminal.

[0041] Wireless sensor network nodes dynamically generate ordinary member nodes, first-level cluster head nodes and second-level cluster head nodes through multi-level heterogeneous clustering routing algorithms, and finally form an ad hoc network.

[0042] The wireless sensor network node includes four parts: sensing module, data processing module, wireless communication module and power supply module. The sensing module mainly includes sensors, A / D conversion circuits and auxiliary circuits to realize data perception, collection, preprocessing and analog-to-digital conversion. The data processing module includes Atmega128L microprocessor, wireless communication interface, RS232 serial interface, clock and monitoring circuit, ...

Abstract

The invention relates to an atmospheric pollution monitoring system based on a wireless sensor network, which comprises wireless sensor network nodes, wireless sensor network sink nodes, local monitoring subcenters, a remote control terminal and a mobile phone terminal. Besides the atmospheric pollution monitoring system based on the wireless sensor network, the invention also customizes a wireless sensor network multi-level heterogeneous clustering routing protocol at the stage of network self-organization; the design of the system is reasonable, the system is easy to deploy, and the intelligent degree is high; when being applied on a large scale, the system can balance the energy consumption of the wireless sensor network nodes, accurately and timely reflect the situation of atmospheric pollution and give the alarm, the wireless sensor network nodes within monitored areas can be conveniently self-networked, and are highly scalable, a large-scale monitoring system can be constructed, and the system is suitable for popularization and application.

Description

technical field [0001] The invention relates to an air pollution monitoring system based on a wireless sensor network, belonging to the field of air monitoring systems. Background technique [0002] At present, the methods of my country's urban air pollution monitoring mainly include: 1) traditional methods, that is, manual sampling laboratory analysis methods. This method can only obtain the monitoring value within a certain period of time in the monitoring area, and cannot perform real-time monitoring, and 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. 2) The current online monitoring is more popular, and the automatic atmospheric environment monitoring equipment imported from abroad is mostly used for monitoring. Although this monitoring method can realize real-time monitoring, the equipment used is comp...
