A monitoring and identifying system for household electricity consumption status and its monitoring and identifying method

Abstract

The present invention provides a monitoring and identification system for household electricity consumption status and a monitoring and identification method thereof. The electricity consumption status monitoring and identification system includes an electrical signal acquisition unit, an environmental signal acquisition unit, a filter unit, an A / D conversion unit, and a control processing unit. , a storage unit, a display unit, a key input unit, a communication unit, an alarm unit, and an incoming line switch; monitor the power consumption status according to the collected electrical signals and environmental signals, and perform load matching through the current harmonic coefficient of the household power grid. When an abnormality occurs, an alarm can be issued in time, and the incoming line switch can be disconnected intelligently, so as to ensure the safety of household electricity consumption. The present invention provides a system and method for monitoring and identifying household power consumption conditions. The load matching is carried out through the current harmonic coefficient of the household grid, the operation status of each load is accurately monitored, and the safety and reliability of household power consumption are improved.

Description

technical field [0001] The invention belongs to the technical field of electric power detection, and in particular relates to a monitoring and identifying system for household electricity consumption status and a monitoring and identifying method thereof. Background technique [0002] With the continuous development of science and technology and the national economy, people's demand for electricity is getting higher and higher. In order to meet people's production and living needs, more and more electrical equipment is used by people. Household is an important part of electricity demand, because it is closely related to people's life, it is paid more attention by electricity workers. [0003] In order to ensure the quality of the household power grid, it is necessary to monitor the household electricity consumption. Traditional monitoring devices use equal-interval synchronous sampling to detect the frequency of the household grid. This sampling method cannot update and adj...

AI Technical Summary

Problems solved by technology

Traditional monitoring devices use equal-interval synchronous sampling to detect the frequency of the household grid. This sampling method cannot update and adjust the sampling points in real time when the grid frequency fluctuates, which will cause errors in subsequent data analysis and processing.
