Building energy consumption abnormity monitoring method and device

Abstract

The invention discloses a building energy consumption abnormity monitoring method and device. According to one specific embodiment of the invention, the method comprises the steps: determining the hourly historical power consumption range of a monitored building according to the historical hourly power consumption data of the monitored building; determining the hourly industry power consumption range for the monitored building based on the historical hourly power consumption data, selected based on preset conditions, of at least one building, the coverage area corresponding to at least one building and the coverage area of the monitored building; determining the hourly standard power consumption range for the monitored building based on the hourly historical power consumption range and the hourly industry power consumption range; selecting a hourly power consumption upper limit value in the hourly standard power consumption range, and generating a hourly power consumption upper limit curve for the monitored building; determining whether the actually obtained hourly power consumption data of the monitored building is greater than the hourly value of the hourly power consumption upper limit curve or not: giving an alarm if the actually obtained hourly power consumption data of the monitored building is greater than the hourly value of the hourly power consumption upper limit curve. According to the embodiment of the invention, the method improves the building energy consumption abnormity monitoring efficiency.

Description

technical field [0001] The present application relates to the technical field of building energy conservation, in particular to the field of building energy consumption measurement, and in particular to a method and device for abnormal monitoring of building energy consumption. Background technique [0002] After the Eleventh Five-Year Plan, the country has gradually carried out energy consumption statistics, energy audits, and energy efficiency publicity work. The sub-item energy consumption data collection and monitoring system of public buildings is an important part of the building energy conservation supervision system. Energy consumption monitoring is generally recognized as the realization of The premise and basis for the quantitative evaluation of public building energy conservation is also an urgent requirement for public building energy conservation. [0003] However, most of today's buildings have unnecessary waste of energy consumption due to automatic control sy...
