Aquiculture pond dissolved oxygen control system

Abstract

The invention discloses an aquiculture pond dissolved oxygen control system comprising a data acquisition and transmission layer and a data storage and sharing layer, which communicate with each other in a wireless way. By studying the characteristics of nonlinearity, greater inertia, long time delay and time-variation of dissolved oxygen change in an aquiculture pond and the difficult problem that a larger culture area is hard to control, and according to the invention, an aquatic product pond dissolved oxygen control system based on a wireless sensor network is designed, comprises the data acquisition and transmission layer and the data storage and sharing layer and forms a wireless sensor network monitoring system for detecting, intelligently controlling and managing dissolved oxygen in the culture pond.

Description

[0001] technical field [0002] The invention relates to the technical fields of an intelligent control method, a control network and information management of dissolved oxygen parameters in an aquaculture pond culture environment, and in particular relates to a dissolved oxygen control system for aquaculture ponds. Background technique [0003] With the increasing promotion and popularization of cage culture and pond culture in the freshwater aquaculture industry, the breeding density continues to increase. Feed feeding, disease prevention, water temperature, and detection and control of dissolved oxygen concentration in water are very important to improve the production and quality of aquaculture. Among them, the detection and control of dissolved oxygen concentration have become the key factors to improve the breeding density, yield and quality. Aquaculture water is the habitat of aquatic animals, and dissolved oxygen is one of the important indicators of pond water quali...

Problems solved by technology

Therefore, some researchers have designed a control method for dissolution from the aspect of monitoring. For example, Zhang Xinrong proposed an intelligent system for monitoring aquaculture environmental parameters using fuzzy control strategies, and He Dongxian invented a remote dynamic monitoring of water quality for aquaculture. System and method, Chen Feng invented a multi-parameter water quality monitoring method and device. The implementation of these control methods has played a certain role in improving the control of dissolved oxygen in ponds. Poor performance, which seriously restricts the benefits and efficiency of aquaculture and the improvement of aquaculture quality; the existing control methods are simple, without in-depth analysis of the characteristics of dissolved oxygen in ponds, and without consideration of the impact of fluctuations in aquaculture density on dissolved oxygen concentration. The value of dissolved oxygen concentration in each stage of aquaculture ponds is set only based on experience, so there are often phenomena of large fluctuations in the concentration of dissolved oxygen in ponds, slow response speed, low control accuracy and high control costs

[0004] The change process of dissolved oxygen parameters in aquaculture is characterized by nonlinearity, instability, large time-lag and time-varying characteristics. Usually, a traditional single closed-loop control method is used to control the dissolved oxygen in ponds, without considering the sudden changes in the breeding density and The impact of changes in other environmental parameters on dissolved oxygen leads to large fluctuations in dissolved oxygen content during aquaculture, which seriously affects the growth and survival of farmed fish in aquaculture ponds
