Abstract

The invention discloses a split-type single-phase intelligent electric energy meter, and the electric energy meter comprises a metering detection module disposed in a power distribution box, and a display module disposed in a user room. The metering detection module and the display module are in communication connection through respective encrypted carriers. The metering detection module comprises a voltage sampling module and a current sampling module, wherein the output end of the voltage sampling module and the output end of the current sampling module are respectively connected with an integrated circuit specially used for electric energy metering. The integrated circuit specially used for electric energy metering is connected with a microprocessor, and the microprocessor is connected with a digital display circuit, an operating key, and a charge control card slot of a display module. The electric energy meter achieves the intelligent control through a single-chip microcomputer, and enables a metering function of the intelligent electric energy meter to be separated from a display function. A display screen of the electric energy meter is installed in the user room so that the power utilization amount of a user can be directly observed. The electric energy meter brings convenience to the user for obtaining the power utilization conditions, makes reasonable use of peak and valley power supply conditions to adjust and schedule the household electric appliances, saves the electricity fee, and improves the power utilization efficiency.

Description

technical field [0001] The invention relates to a split-type single-phase intelligent electric energy meter. Background technique [0002] With the rapid development of science and technology, the electrical energy metering in the power supply field has replaced the mechanical energy meter by the electronic energy meter. Single-phase electronic energy meters also have smart meters ranging from single energy metering functions to multiple functions. In terms of the installation method, one household (unit) has one meter, and there are scattered installations. In order to facilitate the meter reading, maintenance and management of the power supply department, generally speaking, some user meters are concentrated in one (or several) power distribution The reading and display of the meter can only be observed and operated after opening the distribution box. Especially for residents in the community, the distribution box of the meter is usually placed in the ground floor corrid...
