Problems solved by technology

[0017] Due to the above-mentioned defects in the existing ordinary single-phase electric energy meter, it cannot meet the needs of two-way energy interaction in the smart grid
[0018] In addition, the existing ordinary single-phase electric energy meters generally do not have the function of remote meter reading. Even the electric energy meters with remote meter reading function still use wired transmission, and the wiring is troublesome.

Abstract

The invention discloses a single-phase intelligent watt-hour meter with a carrier meter reading module to solve the problems that the conventional watt-hour meter cannot settle the bidirectional electric energy, cannot be read remotely and cannot monitor electric energy quality. The watt-hour meter comprises an electric energy signal sampling module, a single-phase three-wire metering unit, and a microcontroller, which are connected in turn; and the microcontroller calculates positive electric energy E1, negative electric energy E2 and net electric energy E. The watt-hour meter also comprises a liquid crystal display (LCD) module, a power module, a real time clock (RTC) and backup battery module, a pulse output module, a positive electric energy storage unit, a negative electric energy storage unit, a net electric energy storage unit and a carrier communication module, which are respectively connected with the microcontroller, wherein the carrier communication module is linked with a remote meter reading device through a carrier communication channel to remotely read the meter. The watt-hour meter has the following functions: the watt-hour meter can respectively accumulatively meter and store positive and negative time-sharing electric energy, has the real-time measuring function, load recording function, remote meter reading function and electric energy quality monitoring and analyzing function, and can provide a household intelligent interface.

Description

technical field [0001] The invention relates to an electric energy meter, more specifically a single-phase intelligent electric energy meter with a carrier wave meter reading module. Background technique [0002] Existing ordinary single-phase energy meters generally only have the following functions: [0003] (1.1) Metering: cumulative metering of forward electric energy. [0004] (1.2) Time-of-use metering: The electric energy meter has 4 rates, 80 daily periods, 4 annual time zones, 5 time periods, and supports weekends and holidays. Each tariff has a separate meter to record electrical energy. Rate schemes can be switched by combination of day type and season type. [0005] (1.3) Real-time measurement: measure current, voltage, frequency and power in real time, and calculate the load. When the load exceeds the set limit, the electric energy meter will give an alarm. [0006] (1.4) Load record: record electric energy, active power, apparent power, voltage, and current...
