Double-controlled intelligent single-phase electric energy meter with malignant load identification function

Abstract

The invention discloses a double-controlled intelligent single-phase electric energy meter with a malignant load identification function, and belongs to the technology field of electrical safety and energy conservation, the electric energy meter comprises a micro-control unit, and a power supply unit, a two-way relay control module, an electricity metering chip, a data storage circuit, a real-time clock circuit, a liquid-crystal display circuit, a Lonworks intelligent transceiver, an RS 485 communication interface and an infrared communication interface which are separately connected with the micro-control unit. The invention relates to the intelligent electric energy meter, specifically relates to an intelligent multi-fate single-phase multifunction electric energy meter comprising functions including malignant load detection, control and prepayment, can be widely applied to dormitories of students and enterprises and public institutions and other places with centralized people, and can also be applied to places such as home, flat, store and the like, electricity metering and billing, electricity consumption management and safety management are realized. The electric energy meter can serve as a mating device of an energy management system, an energy-conservation control system and an electricity safety management system.

Description

technical field [0001] The invention belongs to the technical field of electricity safety and energy saving, in particular to a dual-control intelligent single-phase electric energy meter with vicious load identification. Background technique [0002] With the development and progress of social economy, many collective dormitories of schools, enterprises and institutions have installed smart prepaid energy meters in order to effectively manage electricity consumption. With the continuous increase of the types of civilian electrical equipment and the increasingly complex electricity environment, it is necessary to limit the use of high-power electrical equipment in such dormitories, such as electric stoves, heating devices, hair dryers, etc. Prevent fires from causing major economic losses; in addition, with the improvement of awareness of environmental protection and energy conservation, many places implement different electricity prices during peak and valley periods, and n...
