黑龙江国土资源数据高效利用云计算模型构建

摘要

黑龙江省国土资源数据利用过程中，普遍出现操作过于复杂，数据过于详细，应用平台单一，物理层资源分布不平衡等问题。为应对和克服实际问题，提高国土资源数据的利用效率，根据黑龙江金土工程现有服务器及网络结构现状，设定节点策略模型，整体分配用户请求；构建基于匈牙利算法的负载均衡模型，解决资源调度问题；建立基于云计算、物联网和GIS的业务平台构建模型，使之构成完整的云计算模型体系。利用虚拟技术和云仿真技术模拟基础条件，测试和验证整体云计算模型的性能，并与现有金土工程进行比较，访问速度、稳定性等指标都有显著提高。%In order to overcome some difficulties , including complex operations , too much data , too many single ap-plication platforms , and uneven physical resources distribution in the utilization of land resources data of Hei -longjiang Province, the authors established a nodal strategy model based on the existing servers and network struc -ture of the Heilongjiang Golden Land Project to realize the overall distribution of user requests , built the load balan-cing model and used the Hungary algorithm to solve the resource schedule problem .The authors also built an effi-cient model of land resources data based on cloud computing , Internet of Things and GIS ( geographic information systems) . The virtual technology and cloud simulation technology are used to simulate the foundation conditions , test and verify the overall performance of the cloud model .Comparing with the Golden Land Project , such indexes as access speed and stability have been improved significantly .
