Double-core intelligent electric meter

Abstract

The invention discloses a double-core intelligent electric meter. A specific embodiment of the double-core intelligent electric meter comprises an electric meter body, and a first power line interface, a second power line interface and an optical fiber interface which are arranged on the electric meter body, wherein the electric meter body comprises a metering module, a communication module and acontrol module; the first power line interface is connected with an input power line loaded with a power carrier signal, and the second power line interface is connected with an output power line; themetering module is used for metering information related to user electricity utilization; the communication module is used for processing the power carrier signal loaded in the input power line or anoptical fiber signal input by means of the optical fiber interface, and converting the power carrier signal or the optical fiber signal into Ethernet information; and the control module is used for determining electricity utilization information of a user according to preset logic and the metering information, and transmitting the power utilization information to an upper terminal or a server. The double-core intelligent electric meter realizes the metering and remote meter reading functions of the electricity utilization information of the user, and provides a network service for the user.

Description

technical field [0001] The application relates to the technical field of remote meter reading, in particular to a dual-core smart meter. Background technique [0002] The power meter is a metering device for electricity management by the power management department. In addition to the basic power consumption measurement function of the traditional power meter, the smart meter can also realize automatic meter reading and self-payment functions. The smart meter is also a terminal device of the smart grid. In order to adapt to the use of smart grid and new energy, it also has intelligent functions such as two-way multi-tariff metering function and two-way data communication function of multiple data transmission modes. [0003] At present, in the meter reading application of the smart grid, there are remote wireless meter reading methods or devices based on the built-in wireless communication module of the smart meter and the cell base station, and there are also remote wireles...
