River channel ecological monitoring system and method

Abstract

The embodiment of the invention provides a river channel ecological monitoring system and method, and relates to the technical field of water ecological environment research. A detector module in a system is installed in a monitoring water area, sound wave signal sources are fixed on fish bodies in the monitoring water area, a signal receiver is electrically connected with the detector module, thesignal receiver is connected with a monitoring terminal, the detector module is configured to receive sound wave signals corresponding to the sound wave signal sources and send the sound wave signalsto the signal receiver, the signal receiver forwards the received sound wave signals to the monitoring terminal, and the monitoring terminal performs processing of the sound wave signals to obtain atwo-dimensional track and a three-dimensional track corresponding to each sound wave signal source. The river channel ecological monitoring system and method can more accurately determine a state of afish group through the obtained tracks and can more accurately obtain behavior response indexes of the fish group for environment change so as to achieve more accurate monitoring of an ecological condition of a river channel where the fish group live. The river channel ecological monitoring system and method have very important meaning of the water ecological environment research.

Description

technical field [0001] The invention relates to the technical field of environmental research, in particular to a river channel ecological monitoring system and method. Background technique [0002] Fish organisms and their living environment are a unified whole, and the two are interdependent, mutually compensated, and co-evolved. Therefore, biological behavior monitoring has become an important means of monitoring, remediation, forecasting and evaluation of river pollution. The use of biomonitoring technology to establish a biotoxicity monitoring system for water environment safety is a research hotspot in environmental science at home and abroad. The behavioral responses of fish to changes in different environmental factors have also been extensively studied. [0003] However, most of the current biological water quality monitoring systems that use fish as the monitoring object use cameras to observe and analyze changes in fish behavior to achieve water quality monitorin...

Problems solved by technology

[0003] However, most of the current biological water quality monitoring systems that use fish as the monitoring object use cameras to observe and analyze changes in fish behavior to achieve water quality monitoring and early warning. Due to the difficulty in post-data processing and large errors, biological monitoring There are large deviations in the construction of the system, and it is difficult to obtain quantitative indicators of fish behavioral responses
