摘要:
构建基于云计算技术的农业信息化管理平台，可以提高农业信息化管理水平，解决农业资源管理中的资源分配不均衡、共享程度低等问题。该管理平台由基础设施层、数据层、应用服务层、管理层和用户访问层构成。基础设施层通过主机服务器和虚拟机构建网络农业资源数据中心。数据层利用云计算技术集中管理基础设施层农业数据，并将其存储于数据库中。应用服务层的农业信息化管理端通过云计算技术实现数据库农业资源调度，并通过离散Kalman滤波算法实时更新处理农业数据。管理层通过农业权限、质量、安全等信息的管理全面协调平台管理的各个阶段，并可通过用户访问层为用户提供访问界面。测试结果表明：该平台数据采集、融合效果好，资源分配均匀合理，而且不同任务数量下均具备较好的负载均衡度，可实现较好的农业信息化管理。
Abstract:An agricultural information management platform based on cloud computing technology was constructed to improve level of agricultural information management and solve problems of unbalanced resource allocation and low sharing degree in agricultural resource management． Infrastructure layer builded a network agricultural resource data center through host server and virtual machine． Data layer used cloud computing technology to manage agricultural data of infrastructure layer and store it in database． Agricultural information management end of application service layer realized agricultural resource scheduling of database through cloud computing technology． Discrete Kalman filtering algorithm was used to update and process agricultural data in real time． Management layer comprehensively coordinated all stages of platform management through management of agricultural authority, quality, safety and other information, and could provide an access interface for users through user access layer． Test results showed that platform had good data collection and fusion effect, uniform and reasonable resource allocation, and had good load balance under different task quantities, which could realize better agricultural information management．
