智能建筑中央空调监控系统存储优化策略研究

随着智能建筑的迅速发展及管理要求的不断提高，监控系统信息管理的实时性、快速性以及存储模式设计的合理性要求也不断提高。针对智能建筑中央空调管控子系统监控点位多、数据存储量大、子系统多样以及管理复杂等特点，构建数据采集平台，利用OPC XML技术，将关系数据模型与XMLDB结合，设计低冗余数据存储及查询优化策略。实验及应用结果表明, 该策略适用于中央空调监控系统的信息管理与优化存储，在一定程度上提高了系统的管理水平和运行效率。

Research on storage optimization strategy for central air conditioning monitoring system in intelligent buildings

With the rapid development of intelligent buildings and the continuous improvement of management requirements, the requirements of real time information management and rationality of the storage mode design in monitoring system are increased simultaneously. Aiming at the features of the central air conditioning data management system with a large number of detecting points, large capacity of storage, variety in subsystems and management complexity in intelligent buildings, the data acquisition platform is constructed and the low redundant data storage and query optimization strategy are designed based on OPC XML technology and the relational data model combined with XML database. The experimental and practical results show that the strategy can be used for information management and optimal storage in central air conditioning monitoring systems, and improve the level and the efficiency of management to some extent.
