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 operation 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 ensuring data security but also improving the resource utilization.
