Sensor network node system for online monitoring, evaluating and early warning of chemical water pollution

Abstract

The invention provides a sensor network node system for online monitoring, evaluating and early warning of chemical water pollution. The sensor network node system comprises a chemical water pollutionmulti-parameter composite array sensor, a wireless sensor information transmission network node module, a chemical pollution monitoring, evaluating and early warning module and a terminal module, wherein the chemical water pollution multi-parameter composite array sensor is formed by integrally compounding a plurality of sensors for element parameters related to the chemical pollution monitoring,evaluating and early warning module; and the wireless sensor information transmission network node module comprises an energy supply module and an RTU (Remote Terminal Unit) tolerant to the environmental structure. The sensor network node system disclosed by the invention can be integrated by selecting different sensors according to the chemical pollution monitoring, evaluating and early warningmodule, can also be randomly moved, is mounted on a floating island or a buoy, can transmit the water quality monitoring data to the terminal module and the chemical pollution monitoring, evaluating and early warning module, has the functions of real-time monitoring, rapid barrier-free transmission, scientific forecast and pre-judgment, real-time early warning and the like, and can reliably and autonomously work for a long time.

Description

technical field [0001] The invention relates to the technical field of water quality monitoring, in particular to an on-line monitoring, evaluation and early warning sensor network node system for chemical pollution of water quality. Background technique [0002] With the acceleration of the industrialization process, the pollution of rivers, lakes, bays and other waters is becoming more and more serious. The problem of water pollution has attracted more and more attention from government agencies to the protection of living water environment. In terms of water environment governance and maintenance, the monitoring of water quality-related parameters is very important. The current water quality monitoring is still mainly in the way of sampling detection or patrol inspection, which is not real-time. The networked in-situ monitoring system has been widely valued in recent years, and it is an effective method for in-situ and real-time measurement of water quality parameters. ...

AI Technical Summary

Problems solved by technology

One is the lack of a sensor node system composed of specific parameter sensors for specific applications. The other is that water quality monitoring is mainly aimed at the detection of water quality parameters in water plants and sewage outlets. The general water quality parameter standard is adopted, and the water quality grade for specific purposes The evaluation model is still very lacking. For example, for chemical pollution, aquaculture, etc., the parameters that need to be monitored for water quality are different. Due to different species of culture, the parameters to be controlled are not completely the same, so the water quality model part is very limited compared to the application requirements.

The third is the problem of environmental adaptability. Generally, the sensor network node system used for water quality monitoring needs to work in the water medium for a long time, facing the actual working environment is relatively harsh, and it also includes the problem of continuous energy supply for field operations; the problem of high temperature inside the watertight structure; if using Solar energy is also facing reliability design problems such as waterproof and windproof; if the design is not in place, the system will work unstable, or even fail or cannot continue to work for a long time
