Design Of Remote Acquisition And Management System For Crop Information Based On Solar Energy

Crop information rapidly and accurately is the basis of the study on crop information collection and the important link,but as a result of C hina's vast,complicated geographical conditions,the lack of infrastructure makes for crop information collection equipment of power supply and data transmission become very difficult.In order to solve these problems,this paper designed a set of crop information remote management system,the system USES solar power supply,battery energy storage,based on the thin client expand USB cameras and sensors to collect information.In terms of management,using B/S development mode,use Java Web technology system.MySQ L5.6 as a database development management tool,developed a stable,visual information acquisition and viewing platform,implement the field crop growth information,intelligentand efficient management of farmland homework,can adapt to remote areas of the agricultural information collection requirements.Specific studies are as follows:(1)The design of remote acquisition device has been completed.The main is to calculate the total power consumption of each module,at the same time for the system to provide a consistent operating voltage for DC/AC inverter using a thin client,as appropriate;then calculate the battery capacity acquisition system required;by calculating the output power of the solar panel according to the capacity of the battery;finally,in order to improve the charging efficiency and avoid overcharge and over discharge damage the lead-acid battery,according to the calculation confirmation output voltage of battery charging current,output current,solar panels and thin client operating voltage,so as to choose the solar intelligent controller for the system of energy management.(2)Completed the design of the system software.Mainly for the USB camera for image acquisition software design,acquisition steps,remote change software design,server database software design,etc.,and the corresponding program code for coding and testing.It solves some key problems,such as multi thread concurrent access to server,database reading,querying data,planning collecting image and environment task and transmitting data resource to server.(3)The development of data display and publishing platform has been completed.A data display and release platform suitable for agricultural crop information is designed and developed.Ajax asynchronous processing technology is adopted to improve the response speed of the system.Users can directly access the platform through the browser,query crop information,and through the analysis and statistics of information to complete the guidance of agricultural production.(4)Adopt a strategy to update server information regularly.That is,the relevant new data information is automatically written to the database and updated to the site system at specified step sizes.Experiments show that the server and database data are almost simultaneously uploaded,effectively solving the problem of low storage efficiency of the information management platform.
