Real-time multiparameter remote water quality monitoring system and method

Abstract

The invention provides a real-time multiparameter remote water quality monitoring system and method. The system comprises an environmental monitoring control center and a plurality of field water quality monitoring devices arranged at a water source area in a distributed mode; each water quality monitoring device is used for sending real-time water quality data to the environmental monitoring control center, and comprises a plurality of sensor units, a signal modulation/amplification and AD (analog/digital) conversion unit, a data storage unit, a liquid crystal display unit, a keyboard input unit, a central control unit, a wireless communications unit, and a power supply module unit; each sensor unit is used for acquiring the parameters of the field water quality in real time; the signal modulation/amplification and AD conversion unit is used for carrying out modulation, amplification and AD conversion on the parameters (acquired in real time) of the field water quality so as to convert the parameters into digital signals, then sending the digital signals to the central control unit; and the central control unit is used for coordinating and controlling the operations of the other units of the field monitoring devices. The environmental monitoring control center is used for receiving, storing and then processing the real-time water quality monitoring data, and carrying out active remote control on the field water quality monitoring devices.

Description

technical field The invention relates to a water quality monitoring system and method. Specifically, the invention relates to a real-time multi-parameter remote water quality monitoring system and method, belonging to the technical field of water environment protection. Background technique With the development of social industrialization in our country, a large amount of industrial wastewater and domestic sewage containing nitrogen and phosphorus are discharged into the water body, thereby accelerating the eutrophication of the lake, leading to the proliferation of aquatic organisms, especially algae, and destroying the ecology of the water body. balance, leading to cyanobacterial blooms. The microcystin in cyanobacteria bloom is a kind of hepatotoxin, which is a strong cancer-promoting agent for liver cancer, and it is the most toxic and harmful freshwater cyanotoxin. Algal toxins are water-soluble and heat-resistant. It is easily soluble in water, the solubility in wat...
