Study on design of solar powered intelligent oxygen-increasing system in aquaculture ponds
摘要
Abstract
In view of the low-level automatization, high energy-consumption oxygen-increasing equipment and low popularity of solar power technologies in the aquaculture industry, an intelligent oxygen-increasing system for aquaculture mainly based on solar energy was designed. In this paper, the solar radiation intensity under various situations was analyzed; the PV array capacity was determined; the daily power generation capacity and the power consumption were calculated to get the matching situations between them so as to achieve the optimal allocation of solar panel capacity and apply it to the intelligent oxygen-increasing system, by the study of the composition, operation mode and characteristics of each part of the solar power supply system along with the solar energy resources of selected locations. The system adopted the design of the hardware circuit and software program based on the ATmega128 single-chip microcomputer, and the techniques of incremental conductance, three-stage charging, inverter circuit, etc. to achieve the maximum power point tracking, intelligent battery charging and discharging, inverter SPWM control, automatic switching power supply, automatic start-stop of oxygen equipment, etc. The results showed that the system can effectively increase the oxygen-increasing efficiency in fish ponds, reduce the aquaculture cost, achieve the environmental protection, and automation of aquaculture. The system has already entered into trial and the trial results proved that the system is stable and reliable, which can improve the oxygen dissolution level in the water, thus satisfying the requirements of energy saving and environmental protection.关键词
