| Agricultural science and technology is the fundamental power of the agricultural modernization.Agricultural technology service is an important approach to make agricultural science and technology available to "Three Agricultures",enhance agricultural production efficiency,improve rural living standard and increase farmers' income.With the development of information technology,it has become a common phenomenon to implement agricultural technology service based on the information system for agricultural technology service.In practice,however,the traditional information system has some defects such as poor timeliness of information and limited service level.The application of cloud technology in information system for agricultural technology service is an effective way to realize the precision and wisdom of agricultural technology service and an important practice in response to the call of constructing "Internet + modern agriculture".Firstly,according to the characteristics of Jiangsu information system for agricultural technology service with infrastructure in a good-condition,rich information resources,diverse types of information systems and multiple modes of science and technology service,this dissertation analyses the problems of repeated construction,limited service objects,single service functions,and scattered information resources.On this basis,the object-oriented analysis method is applied to analyse five components with their functional and nonfunctional requirements of information system for agriculture technology service.The three-layer structure of cloud technology with IaaS,PaaS,and SaaS and micro-service architecture are used to design the frame structure,database structure and function modules of the information system for agriculture technology service to realize the accurate docking of agricultural technology service information in the agricultural chain.The functional modules include management,innovation,service,production and business functions.In addition,the collection and storage scheme based on Hadoop data warehouse is also designed.Finally,the implementation and maintenance of information system for agriculture technology service based on cloud technology are depolyed and the operational effects of related functions are demonstrated by prototype design.Cloud technology is applied to build a comprehensive information system for agricultural technology service which integrates management,innovation,service,production and business.It not only meets the needs of traditional information system for agricultural technology service,such as expert consultation and training service,but also meets new needs arising from the agricultural modernization,such as the matching of agricultural scientific and technological achievements and agricultural socialization services between the supply and the demand.It promotes the resources integration of agricultural talents,science & education and information in Jiangsu and contributes a reference plan for the construction of information system for agriculture technology service nationally. |
