Wireless sensing water quality monitoring and early warning system

Abstract

The invention discloses a wireless sensing water quality monitoring and early warning system. The wireless sensing water quality monitoring and early warning system comprises wireless sensor water quality parameter collecting node, converged nodes and a water quality monitoring center, wherein each wireless sensor water quality parameter collecting node comprises a water quality parameter sensor module, a microprocessor module, a ZigBee module and a solar electricity supply module; the water quality parameter sensor module is responsible for collecting water quality parameters and is connected with the microprocessor module; automatic networking is realized between the water quality parameter collecting nodes through the ZigBee module in a wireless mode so as to form a water quality monitoring wireless sensor network; the converged nodes exchange data with the wireless sensor water quality parameter collecting nodes by the ZigBee module, and exchange data with the water quality monitoring center by a GPRS (general packet radio service) module and the internet; the water quality monitoring center processes the data by an autoregression model algorithm and performs early warning. The system is flexible in layout, can report data in real time, and can realize wireless water quality monitoring and early warning of wide-range water area.

Description

technical field [0001] The invention belongs to the field of water quality monitoring, in particular to a wireless monitoring and early warning system for water quality in large-scale water areas. Background technique [0002] In recent years, with the development of industry and the continuous improvement of people's living standards, the amount of sewage discharge has continued to increase, which has far exceeded the environmental capacity allowed by the natural purification function. The natural water quality has continued to deteriorate, seriously endangering human health and destroying the ecosystem. . In order to ensure the cleanliness of the water environment and water resources, necessary measures must be taken against the pollution sources that cause water pollution, and online monitoring of environmental water quality is very necessary. [0003] For a long time, my country's main water quality monitoring system has some deficiencies: (1) The on-site sampling capac...

AI Technical Summary

Problems solved by technology

[0003] For a long time, my country's main water quality monitoring system has some deficiencies: (1) The on-site sampling capacity of the water quality monitoring center is insufficient, the monitoring frequency is low, the monitoring instruments and equipment in the laboratory are aging, and the large-scale analytical instruments are equipped unbalanced; (2) The mobile monitoring ability Insufficient, the number of mobile water quality analysis and monitoring laboratories is too small, the on-site monitoring ability is low, and the flexibility and mobility are poor; (3) The reliability and accuracy of the monitoring data are not high, so that the monitoring data does not have the validity judgment and intelligent decision-making, etc. Function

[0004] At present, some water quality monitoring systems simply monitor water quality parameters. Although they can enable relevant departments to understand the water quality changes in the monitoring area in real time, they cannot make scientific predictions about environmental change trends in advance, and use advanced scientific algorithms to realize water quality monitoring. Early warning of changes, changing traditional passive monitoring into active early warning is of great significance for water pollution control and even environmental protection
