Single-phase static watt-hour meter with wireless meter reading module

Abstract

The invention discloses a single-phase static watt-hour meter with a wireless meter reading module to solve the problem that the conventional watt-hour meter cannot meet multi-level using requirements of users due to incomplete functions, and cannot be read remotely. The watt-hour meter comprises an electric energy signal acquisition module, a metering module and a microcontroller which are connected in turn, and also comprises a power supply, a meter calibration pulse output module, a data storage module, a display module, a clock and battery module, a time sharing module and a wireless communication module which are respectively connected with the microcontroller, wherein the wireless communication module is linked with a remote meter reading device through a wireless communication channel to remotely read the meter. The watt-hour meter has the following functions: the automatically networked wireless communication can realize remote meter reading; and the watt-hour meter has the functions of calculating time sharing multiple rates, metering demanded quantity, recording events and load curve, measuring load data such as voltage, current, active power, apparent power, frequency and the like, detecting undervoltage, overvoltage, loss of current and overcurrent, and the like, has complete functions and can meet the multi-level using requirements of users.

Description

technical field [0001] The invention relates to an electric power meter, in particular to a single-phase static electric energy meter with a wireless meter reading module. Background technique [0002] Existing ordinary single-phase electric energy meters generally only have the functions of measuring electric energy and time-sharing multi-rate, and can display normally at low temperatures. Generally, LED digital tubes are used, but the display content is small and the power consumption is large. [0003] Most of the ordinary single-phase electric energy meters currently used are mechanical electric energy meters. The mechanical electric energy meter is measured by mechanical rotation, so the installation of the electric energy meter has strict requirements. The angle from the vertical is different, or even obviously inclined, which will make the energy measurement unbalanced, resulting in inaccurate measurement, that is, the result of slow walking, stopping or even non-walk...
