The Research Of Sub-metering System For Existing Large Public Buildings

Kinds of sub-metering system of intelligent building is one of the effective ways ofenergy saving and consumption reduction, Through the installation of the measuringequipment and system, Energy-using units (unit) energy production, conversion andconsumption to conduct a comprehensive inspection and monitoring. In order topromote energy saving、stop waste, Improve energy utilization efficiency and economicbenefits, so as to realize the "energy saving, consumption reduction, efficiency"purposes.In this paper, the author in the process of both large public buildings energy auditfound problems and actual situation, proposed the itemized metering system based onenergy audit. The kinds of measurement system based on both the large public buildingsenergy audit, First to building energy used according to different types of classification,and investigate the power consumption of each subsystem rules and actual use of energy,Then according to the survey, each subsystem according to their own characteristicsinto precise metering section and approximate metering section. In the meet of meteringsystem balance check premise, achieve good purpose of measurement. The train ofthought for the present solve both large public construction of measurement issuesprovides a good solution.At the same time, according to the energy audit found in the human energy wastephenomenon, combined with the Internet of things technology is developed based onGPRS/GSM technology of the intelligent controller, the controller is based on51single-chip microcomputer and Siemens TC35V1module programming developed in, through to various office environment with electrical integration on the controller, wecan direct from the phone to complete for the different operation to use electricalappliances, the formation of electric equipment of unmanned, long-range, andintelligent control. So as to further reduce the itemized metering of energy wastephenomenon, improve the measuring accuracy based on energy audit itemized meteringsystem.
