Environmental data restoration/filling method and system

Abstract

The invention relates to an environmental data restoration / filling method and system. The system comprises the following steps: drawing box diagrams of indoor and outdoor environment data with different attributes based on ORIGIN software; determining an abnormal data set according to the box diagram; deleting continuous abnormal or missing multi-attribute data in the abnormal data set by adoptinga tuple ignoring method to obtain a processed abnormal data set; repairing or filling continuous abnormal or missing single attribute data by adopting a distance weighted KNN algorithm; segmenting the processed abnormal data set; repairing or filling discontinuous abnormal or missing data in the segmented abnormal data set by adopting an improved exponential weighted moving average model; and integrating the repaired or filled data. According to the method, the problems of data missing, data exception and the like in different conditions in indoor and outdoor environment monitoring data in abig data platform can be systematically solved in a classified mode, and the method and the system have important significance in improving the data quality and guaranteeing the data mining quality and efficiency.

Description

Technical field [0001] The present invention relates to the field of data restoration, in particular to an environmental data restoration / filling method and system. Background technique [0002] In the context of the information technology revolution of the Internet of Things, smart home and building energy consumption management and control systems combine advanced sensor measurement technology, information technology, communication technology and computer technology to better improve the living environment and guide building energy conservation The landing of the career. Therefore, real-time monitoring of building indoor and outdoor environmental parameters has become an important data foundation for big data building energy consumption control, smart home scene control, and energy consumption simulation. At this stage, due to data collection terminal failures, power outages, network failures, central server crashes and other reasons, data cannot be uploaded, there are missing...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a method and system for repairing / filling environmental data, which can systematically and categorized solve problems such as missing data and abnormal data in different situations in the indoor and outdoor environmental monitoring data in the big data platform, and improve data quality. It is of great significance to ensure the quality and efficiency of data mining
