Intelligent oxygen supplement system for aquiculture

Abstract

The invention provides an intelligent oxygen supplement system for aquiculture. The system comprises a data monitoring node and a data control node. The data monitoring node is composed of a first central processing unit and a data acquisition module. The data acquisition module comprises a dissolved oxygen sensor and a temperature sensor. Outputs of the dissolved oxygen sensor and the temperature sensor are connected with a data input terminal of the first central processing unit. The data control node is composed of a second central processing unit, an oxygen supplement module and a user interaction module. The second central processing unit receives data transmitted by the first central processing unit. An output of the data control node is connected with an aerator drive circuit to control an aerator. The aerator drive circuit and the aerator form the oxygen supplement module. The second central processing unit operates a feedback control algorithm, and can drive the aerator to realize automatic dissolved oxygen amount adjustment according to real-time acquisition information and a reasonable scope of dissolved oxygen amount in different temperatures. The invention supports functions of wireless transmission, real-time monitoring, automatic oxygenation and the like, cost is low, operation is simple, and an application scope is wide.

Description

Technical field [0001] The invention belongs to the field of agricultural modernization, relates to the improvement of the aquaculture environment, and specifically relates to an intelligent oxygen supplement system for aquaculture. Background technique [0002] Aquaculture waters are the living environment of aquaculture animals, and every aquaculture animal needs a water quality environment suitable for its survival. If the water quality environment can meet the requirements, aquaculture animals can grow and reproduce. If the water in the water quality environment is polluted, some water quality indicators are beyond the range of adaptation and tolerance of aquaculture animals, and aquaculture animals cannot grow normally. The severe ones may cause a large number of deaths of aquaculture animals. Dissolved oxygen refers to molecular oxygen dissolved in water, which is an indispensable condition for the survival of aquatic organisms and plants. For several major fishes cultiva...

Problems solved by technology

However, the monitoring system is expensive, complicated to install, difficult to maintain and difficult to operate, so it is not suitable for the existing small and medium-sized aquatic products companies and individuals in our country.

At present, the application of the AVR single-chip microcomputer designed by Li Zengxiang and others in the detection of dissolved oxygen in fish ponds can monitor and control the switch of the aerator in real time, but because the system does not consider the difference of dissolved oxygen at different temperatures, and the monitoring and control must Together, wireless control is not possible, and the circuit for controlling the aerator is very demanding and difficult to implement. It is not suitable for use in the actual situation where the distance between the fish pond and the power supply room is far away.
