Development of Monitoring System of Building Energy Consumption

Abstract

In order to solve the serious problem of high energy consumption in large public buildings and government office buildings, this paper develops the monitoring system of building energy consumption (MSBEC), which could monitor not only energy consumption data, but also energy quality. Firstly, this paper designs the hardware subsystem with three-layer structure. At the information center layer, four data acquiring servers are linked with a double control disk array subsystem, which ensures the stability of monitoring system. The network layer adopts the RS485-TCP/IP mode and the RS485-ZigBee-TCP/IP mode to collect information from RS485 protocol terminal modules. Then this paper introduces the software subsystem with multi-tier distributed application services, which contains the persistence layer, the application layer, and the representation layer. Every layer is independent relatively, and may be developed by different technology. Based on the sufficient energy monitoring data, MSBEC could provide technical support for later energy retrofit.
