Water pollution monitoring biosensor, monitoring system and monitoring method

Abstract

The invention discloses a water pollution monitoring biosensor, a monitoring system and a monitoring method, wherein the biosensor comprises an aquatic organism which is a living bivalve organism, anoptical grating fixing structure, and an optical grating; the optical grating fixing structure comprises a first fixing base, a second fixing base and an elastic beam piece, the elastic beam piece isof an arch structure, a first fixing part and a second fixing part of the elastic beam piece are mounted on the first fixing base and the second fixing base respectively, and a bent part in the middleof the elastic beam piece is located between the two fixing bases; the two fixed bases are respectively fixed on the surfaces of two shells of the aquatic organism; the optical grating is a fiber Bragg grating and is adhered to the outer side of the bent part of the optical grating fixing structure; opening and closing of the two shells of the aquatic organism drive the bent part to expand or contract through the two fixing bases, then the optical grating is driven to regularly expand or contract, and signal changes are generated.

Description

technical field [0001] The invention relates to the technical field of water pollution monitoring, in particular to a biosensor for water pollution monitoring, a monitoring system and a monitoring method. Background technique [0002] The information disclosed in this background section is only intended to increase the understanding of the general background of the present invention, and is not necessarily taken as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to those skilled in the art. [0003] Conventional water quality monitoring often requires local sampling at the water source, and the sample water is brought back to the laboratory or testing center for offline testing. This technical method has a long monitoring cycle, poor timeliness, poor data reliability, and high cost consumption. Online monitoring is not possible. [0004] At present, there are some electronic products that can realize online water qual...

Problems solved by technology

[0003] Conventional water quality monitoring often requires local sampling at the water source, and the sample water is brought back to the laboratory or testing center for offline testing. This technical method has a long monitoring cycle, poor timeliness, poor data reliability, and high cost consumption. Unable to realize online monitoring

[0004] At present, there are some electronic products that can realize online water quality monitoring, but such electronic products need power supply, and it is difficult to deploy them at multiple points in large-scale waters, especially in sea water, where they are easy to be attached by aquatic organisms and become invalid. Long-term work in marine corrosive environment

It is a new technology to install sensors on organisms to realize environmental monitoring, but most of them are realized by electronic sensors, which also have problems such as corrosion resistance, difficulty in power supply, and susceptibility to signal transmission interference, which cannot be monitored online for a long time. Conducive to the monitoring of water pollution
