Automatic detection method for water quality parameters of large-area river crab aquaculture pond

Abstract

The invention discloses an automatic detection method for water quality parameters of a large-area river crab aquaculture pond. According to the method, a river crab culture pond automatic navigationship carries a water level, water quality and water temperature sensor to acquire parameters such as dissolved oxygen, pH value and water temperature of each grid bottom layer and middle layer of thewhole pond and the pond water level; in combination with sampling time and GPS / Beidou navigation system information of an automatic navigation ship, a water level, water quality and water temperatureparameter database of each grid in the whole domain of the river crab culture pond at a limited time point is established; water level, water quality and water temperature sensors are arranged at specific points on the bottom layer of the pond, and a river crab culture pond specific point water level, water quality and water temperature parameter long-term historical database is established in combination with longitude and latitude information of the specific points. The current river crab culture pond global water level, water quality and water temperature parameters are established througha neural network fitting method in combination with a river crab culture pond global water level, water quality and water temperature parameter database at a limited time point according to the parameter data of each current specific detection point to form a pond global grid water quality, water level and water temperature dynamic information distribution diagram.

Description

technical field [0001] The invention relates to an automatic detection method of water quality parameters in a large-area river crab breeding pond, in particular to real-time detection of water temperature and water quality parameters, which is based on neural network fitting to estimate the water quality of each point in the whole area, and combined with GPS / Beidou navigation technology to form grids in the whole area of ​​the pond Distribution map of water quality, water level and water temperature dynamic information. Background technique [0002] River crabs are rich in protein and trace elements, with high nutritional value and delicious taste. People's demand for river crabs is gradually increasing, and the river crab breeding industry has developed rapidly. However, the traditional aquaculture model lacks scientific guidance and blindly pursues output and economic benefits. It is prone to overcapacity, high-density aquaculture, irrational feeding, pesticide applicatio...

AI Technical Summary

Problems solved by technology

At present, most of the monitoring systems are fixed measurement systems. Multi-point measurement can accurately measure the water quality, but the cost is high, and it is difficult for ordinary farmers to accept

However, unmanned ship technology is mostly used in scientific research surveying, mapping, monitoring, etc., and is rarely used in agriculture; domestic river crabs have a large water surface, and river crabs have a strong sense of territory. They cannot move in a large range and can only look for food in their own vicinity , the distribution density of river crabs is uneven, and the mobile detection ship cannot monitor the entire large water area in real time and efficiently
