Semi-intrusive load monitoring system and method applied to household power distribution box, and application of system

Abstract

The invention relates to the technical field of power load monitoring, and discloses a semi-intrusive load monitoring system applied to a household power distribution box. The semi-intrusive load monitoring system includes a sensing module, the sensing module includes a plurality of current sensors and air circuit breakers, the current sensors located on a total circuit are connected with an earthleakage protection module, the current sensors located on a branch circuit are connected with a data acquisition module, the data acquisition module is connected with a data processing and controlling module, the data processing and controlling module is connected with a display module and a storage module in a bidirectional mode respectively, and power is supplied by the data acquisition modulethrough a power supply module. The invention further discloses a detection method and specific application. According to the semi-intrusive load monitoring system applied to the household power distribution box, the detection method, and specific application, the real-time judgment of the running status of each air circuit breaker loop electrical appliance in the household power distribution box is realized through the semi-intrusive load monitoring method, and the earth leakage protection function is achieved.

Description

technical field [0001] The invention relates to the technical field of electric load monitoring, in particular to a semi-invasive load monitoring system, method and application applied to a household distribution box. Background technique [0002] Electric energy is widely used in various fields related to industrial production and people's life, and has become an indispensable "energy element" for society. However, with the rapid development of the world today, energy consumption is becoming increasingly tense, and electric energy, as a secondary energy source most relied on by industrial society, is also facing various shortage and waste problems. In order to plan, distribute, and use electric energy more reasonably, it is necessary to monitor and identify the load at the power consumption end. Establishing a visual interface on the residential side to monitor the energy consumption of household appliances can help users formulate strategies to save electricity, which is o...

Problems solved by technology

[0003] The traditional load monitoring and identification method obtains the power consumption behavior of each electrical equipment by installing hardware devices such as sensors at each monitored load. This intrusive monitoring method requires a lot of time and money in installation and maintenance. Can not meet the needs of the continuous development of the power system
