基于多租户模式的节能检测及监控系统

Energy-saving detection and monitoring system based on multi-tenant mode

针对城市大量供热企业能耗高、缺乏统一有效的节能检测及监控技术的现状,为降低研发和运维成本,设计并实现了一种基于多租户模式的节能检测及监控系统。采用隔离数据库,共享应用实例的体系架构以及基于元数据驱动的策略,设计了支持多租户的数据存储模型与多租户个性化定制的核心机制,实现系统的可配置,为租户按需提供服务。在此基础上,针对多数据源间的动态选择以及数据安全问题给出了一套解决方案,从而使得一套应用程序可以同时为多个租户提供服务,在保证数据安全的同时又提高了资源利用率。

Abstract：In view of the present situation that heating enterprise＇s energy consumption is large and lack of effective energy saving detection and monitoring techniques to reduce the development and opera tion costs, the paper proposes an energy-saving detection and monitoring system based on multi-tenant mode. It uses a separate database, shares application instance architecture and metadata-driven strategy, designs the core mechanism supporting multi-tenant data storage model and personalized customization of multi tenant, implements the configuration of the system, and provides on-demand service. On this basis, aiming at dynamic selection among multiple data sources and data security issues, a solution is given to make one set of applications be able to provide services for multiple tenants, thus not only ensu ring data security but also improving the resource utilization.
