Problems solved by technology

Therefore, the electric energy meter cannot be selected too large
If the selection is too small, it is easy to burn out the electric energy meter
[0007] Electric energy meters in the prior art are developing towards intelligence, such as providing remote meter reading interfaces, etc., but generally speaking, the electric energy meters in the prior art have the following defects: (1) the measurement accuracy of the electric energy meter still needs to be improved; 2) The function of the electric energy meter is single, and it is still limited to the detection operation of the power line, and the public space occupied by the electric energy meter is not fully utilized, such as the public space in the stairwell

Embodiment Construction

[0020] The implementation of the intelligent electric energy meter of the present invention will be described in detail below with reference to the accompanying drawings.

[0021]The working principle of the electric energy meter is as follows: when the electric energy meter is connected to the circuit under test, an alternating current flows in the current coil and the voltage coil, and the two alternating currents generate alternating magnetic flux in their iron cores respectively. The alternating magnetic flux passes through the aluminum disc and induces an eddy current in the aluminum disc; the eddy current is subjected to force in the magnetic field, so that the aluminum disc obtains torque (active torque) and rotates. The greater the power consumed by the load, the greater the current passing through the current coil, the greater the eddy current induced in the aluminum disc, and the greater the torque that makes the aluminum disc rotate. That is, the magnitude of the to...

Abstract

The invention relates to an intelligent electric energy meter, comprising a FLASH storage device, a three-phase electric energy metering device, a figure appearance frequency detection device and a Sunplus SPCE061A chip. The three-phase electric energy metering device is used for detecting and outputting the active power of a three-phase electric power circuit; the figure appearance frequency detection device is used for detecting the appearance frequency of each figure in a staircase; the Sunplus SPCE061A chip is in connection with the FLASH storage device, the three-phase electric energy metering device, and the figure appearance frequency detection device, controls the operation of the three-phase electric energy metering device, and meanwhile determines the identity of a figured based on the output of the figure appearance frequency detection device. According to the invention, the intelligent electric energy meter can realizes the prepared authentication on the figure identity in a staircase by means of present device resources, thereby guaranteeing building resident living safety.

Description

technical field [0001] The invention relates to the field of electric energy meters, in particular to an intelligent electric energy meter. Background technique [0002] An electric energy meter is an instrument used to measure electric energy, also known as an electric meter, a fire meter, or a kilowatt-hour meter, and refers to an instrument for measuring various electrical quantities. [0003] The energy meter is divided according to the purpose, and can be divided into: active energy meter, reactive energy meter, maximum demand meter, standard energy meter, multi-rate time-sharing energy meter, prepaid energy meter (coin type, magnetic card type, Electric card type), loss electric energy meter, multi-function electric energy meter and intelligent electric energy meter. [0004] According to the working principle, the electric energy meter can be divided into: induction type (mechanical type), static type (electronic type), and electromechanical integrated type (hybrid t...
