| State-operated farm generally has the characteristics of administrative management sys-tem and large-scale agricultural production. Because of the vast land and large and levelfarmland, so not only agricultural mechanization level is very high, at the same time, a lot ofinformation technology is also got more extensive application and has obtained the certaineffect. But currently there are some widespread problems in the process of agricultural in-formation technology in the application: lack of basic application, costly system constructionand running, repeated construction and so on, make it hard for information technology to ser-vice agricultural production effectively and consistently and create economic and social ben-efits. In this paper, based on the application of state farms from two aspects: agricultural pro-duction management and agricultural data sharing, we carried out the following researchworks:1. The characteristics of agricultural production management requirements, roles, per-missions, and personnel requirements are analyzed by XinJiang production and constructioncorps herd used as application demonstration unit, crops production management informationsystem is designed and developed based on B/S (Browser/Server) and C/S (Client/Server)mode. The system used the layered architecture, object-oriented technology and role-basedaccess control technology, to solve the basic problems of agricultural production informatio-nization in the herd by using data acquisition, analysis, and management in the process ofagriculture production management as the research object, improving the efficiency of agri-cultural production and management as the goal, which could used as the basis platform forfurther implementation of agricultural information technologies.2. Agricultural data is classified reasonable and the data structure characteristics is ana-lysed, the schema files is designed based on XML and AgroXML, so as to realize consistentdata representation by using normative XML files to describe agricultural data, and to solvethe problem of consistent data understanding between different systems. At the same time, inorder to realize the mutual interpretation of data between different software systems, dataparsing module is design and developed based on the.net platform.3. The characteristics of all kinds of distributed technology and application scenarios arecompared. In combination with the realistic characteristics of widely distribution and dynam-ic changing of agricultural data providers and consumers (agricultural departments such asgovernment, enterprises and so on), the agricultural data is rationally abstracted as networkresources. REST (REpresentational State Transfer, declarative State Transfer) technology isused to design data access service interface and the resource path, and RESTFul Web servicesare developed based on.net platform and WCF (Windows Communication Foundation)technology, which could achieve agricultural data interaction between heterogeneous sys-tems.Specific research results are as follows: 1. The production information management system is developed based on the productionand construction corps state-owned farm scale, which manage many kinds of data such asfarmland, personnel, crop, agricultural production and so on, and could provide automaticgeneration of many reports such as spring sowing report and irrigation statistical report,which greatly improved the efficiency of data processing, analysis and statistics; The accesscontrol mechanism of combination with roles and time and the3kinds of roles such as agri-cultural technicians, agricultural production managers, system administrators are designed;The fields electronic map is drew, the visual expression of basic data and agricultural produc-tion data has realized by using WebGis technology. Through the application of the system, theherd’s agricultural production and management efficiency has improved, and at the same timeaccumulated acomprehensive and standard farmland management data, which can be as amanagement foundation and data security for further comprehensive implementation of agri-cultural information technology.2. Four schema files are designed by using XML file as agricultural data expression car-rier, which covers the35basic data types and29compound data types that agricultural in-formation expression commonly used, and the standardization of the existing data descriptionis preliminarily realized. At the same time, data parsing modules are developed based on C#language to realize mutual conversion between the four objects: database records, programmemory objects, XML files, JSON (JavaScript Object Notation) objects, which form thefoundation of information description and multiform reading for data sharing.3. The agricultural data sharing framework are designed based on REST technology, and56resource paths are designed for eight kinds of farmland management data, at the same time,the corresponding data access interface and service implementation is developed based onWCF technology.The main innovation points as follows:1. the corps farms is an agricultural production organization entity under administrationmanagement system, involves large amount of people, data, and management issues in theprocess of agricultural production, and has very complicated and unique application require-ments. This paper preliminary exploration on the issues such as technology platform, applica-tion model, operation process and so on which should solve in terms of management infor-matization under such special application requirement.2. The trends of agricultural data sharing between different systems and potential dataproviders and consumers are analyzed; Two issues of data description and data access thatmust solved for data sharing are proposed, the solution design and implementation develop-ment are achieved by using XML and REST. |
