Application Research Of Solar Energy Intelligent Increasing Oxygen System In Aquaculture

In recent years, some policies about agriculture make agriculture develop rapidly. As a part of the agriculture, aquaculture have significantly been improved in technology,but there are still some problems. The automatic control level for aquaculture environment regulation is lower and the aerating equipment belong to high energy-consumed device. These are main obstacles for further development of aquaculture. Nowadays ,the environmental pollution is serious, and traditional energy source is scarce. Developing a system of energy conservation and environmental protection used in increasing oxygen based on solar power supply is of great significance.In view of the situation of aquaculture and solar energy technology,this paper designed a set of intelligent increasing oxygen system by solar power supply. It can effectively improve the efficiency of increasing oxygen and achieve environmental protection and automation of aquaculture.In the system,solar power supply is the main research field . The paper puts forward the overall design scheme of the system based on Aquaculture technology and solar energy technology research status at home and abroad. The system is mainly composed of solar cell,MPPT control circuit, charging and discharging control circuit,battery,inverter,AC load. Through the comparison of several different maximum power point tracking methods,Incremental conductance is selected to realizing the MPPT control . The battery charging circuit is designed by using three stages of charging method . According to the characteristics of the load and the related inverter technology, a inverter with the actual needs is designed .It can supply electricity for the load. The design of system hardware and soft ware are completed based on Micro-computer . This system has the function of the maximum power point tracking, intelligent battery charging and discharging, SPWM control,switch power supply source and automatic start-stop of equipment.After simulating and testing, the results show that the system can be fast tracking of maximum power point of solar energy and output AC voltage to meet the demand of the load,and control the increasing oxygen device according to the parameters of detecting.
