The Design And Development Of A Soil Testing And Formulated Fertilization System Based On GSM Technology

With the rapid development of the Computer Control Technology, Database Storage Technology and Wireless Telecommunication Technology in industrial production, the Remote Monitoring and Controlling System, which is based on Wireless Telecommunication Technology, has spread in all walks of life. The Technologies mentioned above are also taking over an important position to promote the process of the Soil Testing and Formulated Fertilization(STFF), they can benefit the standardization of fertilizing management and transportation of fertility calculation----In order to motivate agricultural informationization and make the STFF widely used, it is necessary to design such information monitoring platform based on series of remote telecommunication technologies, by which farmers and related users can look up and obtain fertilization data conveniently and in time, meanwhile, it is the best way to increase their fertilzing experience online.In recent years, the J2EE multi-layer architecture based on Browser/Server mode tend to be maturer, also, the application of Struts+Spring+Hibernate(SSH) simplify the development progress and increase the programming efficiency. The J2EE technology is greatly relied on in several fields such as electricity, economy, environment and agriculture. The fertilization decision making and monitoring system built by J2EE takes advantage in transplantability and extensibility. In terms of remote wireless data transmission, because of the advantages of wide network coverage range and high cost performance, the usage of GSM wireless transmission function conforms to the trend of the agricultural informationization, meantime, it can strengthen and consolidate the application of wireless communication technology in agriculture, thus achieve the goal of stable and efficient agricultural information acquisition.In this article, a management system for STFF, which is constructed by J2EE and GPRS technology, has realized measurement and monitoring of crop fertilization, the following aspects are its major works:(1) Develop The STTF system by using the SSH architecture in B/S mode by J2EE. And the technology Direct Web Remoting(DWR), also called reverse Ajax, has been used to carried on the message push operation from server to client;(2) Achieve the dynamic control of short message transmittion and receive functions by using SIM300S and STC12C5A60S2single-chip computer to complete the hardware circuit connection to PC and serial port communication design, thus; (3) Conduct soil testing and fertilization calculation by using nutrient balance and fertilizer recommendation function;(4) Provide data foundation for system development by using My SQL5.0database to realize the user, crop, soil, fertilizer, and short message data storage and updating.
