Electric energy meter capable of providing internet payment data

Abstract

The invention belongs to the technical field of measuring instruments, and particularly relates to an electric energy meter capable of providing internet payment data. The electric energy meter comprises a metering mechanism, a shell, a panel, a side window, a digital display area, a USB socket, a password area, a processing device, a receipt printer and a storage device. The digital display area is arranged on the panel. The USB socket is arranged on the side face of the electric energy meter. The password area is arranged on the upper surface of the shell. The processing device and the receipt printer are arranged inside the shell. The password area, the processing device, the receipt printer and the USB socket are connected through a data transmission line. The USB socket, the password area, the processing device, the receipt printer and the storage device are arranged on the electric energy, a password is input in the password area and verified through the processing device, expense information is stored into the storage device, electric charge is paid through an internet payment terminal, then, the storage device is in butt joint with the USB socket, the processing device controls the receipt printer to print a receipt, and the whole process is convenient and rapid.

Description

technical field [0001] The invention belongs to the technical field of measuring instruments, in particular to an electric energy meter capable of providing online payment data. Background technique [0002] The abbreviation of watt-hour meter is an instrument used to measure electric energy, also known as watt-hour meter, fire meter, watt-hour meter, and kilowatt-hour meter. It refers to the abbreviation of watt-hour meter for measuring various electrical quantities. In the circuit, there is an alternating current flowing 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 disk, and in the aluminum disk The eddy current is induced; the eddy current is subjected to the force in the magnetic field, so that the aluminum disc gets the torque (active torque) and rotates. The greater the power consumed by the load, the greater the ...

AI Technical Summary

Problems solved by technology

There are many classification methods of electric energy scales. According to the principle, they can be divided into inductive electric energy meters and electronic electric energy meters. Inductive electric energy meters use the principle of electromagnetic induction to convert voltage, current, and phase into magnetic torque, and push the aluminum disc to rotate. The shaft (worm) drives the gear to drive the drum of the meter to rotate. The process of rotation is the process of accumulating time. At present, residents usually use two methods to pay electricity bills. Copy the electricity and charge a certain fee. Another method is to buy a recharge card from the power company. Every time the electricity fee is used up, you have to go to a fixed point to pay the fee, which is time-consuming and laborious.
