The design and implementation of a low-cost power monitoring system for campus power monitoring

摘要

The real-time electricity data can be regarded as a building event sensor to detect various events in a building. The idea is that the use of electricity comes mainly from the users in the build, the trends and changes in electricity data reflect the behavior of the users. For example, the increase of electricity may come from the user turning on the air conditioner, and the reduction of electricity may come from the user turning off the light and leaving the laboratory. In this paper, we report our design and implementation of power monitoring devices to collect actual electricity usage data from NCHU campus and propose to analyze the power data in the building space by heat map views. We collected more than 7 billion electricity usage records. We also made the data set publicly available to the public in the hope that it will be helpful in the field of electricity data research.
