Design And Application Of Solar Battery Power System In Field Of "Four Situation" Observation System

It is an important method for using the Internet of things and information technology to p-recisely manage and intelligently control the modern agriculture.It makes great contribution to a new agricultural production patterns,which is a combination of regionalization and low-cost information technology.And it also helps to promote a wise agricultural development.The paper mainly studies on the design and applying of the independent solar power syst-ems in the monitoring system of the fields.The project requires immediate data monitoring on the field crops,seeding,disasters and pests and weeds.Therefore we set up cameras in the fie-lds and use solar energy to provide electricity according to the actual situation.The main wor-ks include the following aspects.Firstly the paper studies on the principle of solar cells,based on the analysis of the volt-ampere characteristics and power characteristics of solar cells.It summarizes the specific impac-ts of environmental factors on the outputs,and Simulink is being used to simulate the solar ce-lls.Secondly algorithm of three commonly used maximum power point trackings is being studi-ed and simulated in the paper and the advantages and disadvantages are being summarized res-pectively.Therefore a hybrid maximum power tracking algorithm is proposed.The algorithm,c-ompared with other algorithms on its superiority,is simulated by using Matlab/Simulink.Finally,the paper designs the solar power supply system in the monitoring system in the fields.Param-eters of each module are determined and a practical monitoring system is built by analyzing th-e principles of the whole electricity supplying system.Zigbee module is used in the project to the to perform real-time sampling and monitoring of the power usage of an independent solar power system.
