lectricity Smart Meter and Electricity Meter PCB with Components
Detail
Smart meter is composed of measurement unit, data processing unit, etc. It has the functions of energy metering, information storage and processing, real-time monitoring, etc. It is the smart terminal of smart grid.
The functions of smart meter mainly include dual display function, prepaid function, accurate charging function and memory function.
The specific functions are introduced as follows
1. Display function
The water meter with general display function will also be available, but the smart meter has dual display. The meter displays the accumulated power consumption, and the LED display displays the remaining power and other information.
2. Prepaid function
Smart meter can charge electricity in advance to prevent power failure due to insufficient balance. The smart meter can also send out an alarm to remind users to pay in time.
3. Accurate billing
The smart meter has a strong detection function, which can detect the flow of the wiring board and socket, which can not be detected by ordinary meters. The smart meter can accurately calculate the electricity bill.
4. Memory function
Ordinary electricity meters record a lot of user information, which may be reset if there is a power outage. The smart meter has a powerful memory function, which can save the data in the meter even if the power is cut off.
Its working principle is that smart meter is an advanced metering device based on modern communication technology, computer technology and measurement technology, which collects, analyzes and manages electric energy information data. The basic principle of smart meter is to rely on A/D converter or metering chip to carry out real-time acquisition of user current and voltage, analyze and process through CPU, realize calculation of forward and reverse, peak valley or four quadrant electric energy, and further output the electric quantity and other contents through communication, display and other methods.
