The smart energy meter is the smart terminal of the smart grid. It is no longer an electric energy meter in the traditional sense. In addition to the basic power metering function of the traditional electric energy meter, the smart meter also has two-way multiple functions in order to adapt to the smart grid and the use of new energy. With intelligent functions such as tariff metering functions, user-side control functions, multiple data transmission modes, two-way data communication functions, and anti-theft functions, smart meters represent the future development direction of intelligent terminals for end users of energy-saving smart grids.
In traditional smart meters, the user pays a fee to charge the smart IC card and enters it into the meter. Then the meter can supply power. After the power in the meter is used up, it will automatically switch off and cut off the power. The new smart meter is currently perfect for online purchase of electricity, just like a mobile phone. Recharge is as easy as it is. Electronic smart meters are high-tech products developed in recent years on the basis of electronic meters. Its composition and working principle are quite different from traditional induction meters. The electronic smart meter is mainly composed of electronic components. Its working principle is to first sample the user's power supply voltage and current in real time, and then use a dedicated electric energy meter integrated circuit to process the sampled voltage and current signals and convert them into The pulse output proportional to the electric energy is finally processed and controlled by the single-chip microcomputer, and the pulse is displayed as the electric power consumption and output.
