Carrier wave smart meter, also known as carrier energy smart meter, is an intelligent energy smart meter with carrier communication function. It integrates carrier communication chips into the energy smart meter and uses power lines as data transmission media to achieve remote smart meter reading, control, and other functions. The advantage of this technology is that it does not require additional communication lines and can directly utilize the existing power network for data transmission.
The working principle of carrier smart meter:
The working principle of the carrier smart meter is based on modulation and demodulation technology. The electric energy smart meter samples the voltage and current signals through a resistive voltage divider network and shunt components, and then sends them to the electric energy smart metering chip. Inside the smart metering chip, the instantaneous power measurement of the measured electrical energy is completed through differential amplification, A/D conversion, and multiplication circuits. Then, through low-pass filtering and a "digital/frequency" converter, output a frequency pulse signal proportional to the average power of the satellite's electrical energy. High frequency pulse output is sent to the chipset for processing, recording the total electricity and feeding data such as electricity into the power line.
So, what is the use of a carrier smart meter?
Carrier smart meters are widely used in fields such as smart grids, remote smart meter reading systems, and power demand management. Through carrier communication technology, remote automatic smart meter reading of electric energy smart meters can be achieved, improving smart meter reading efficiency and reducing labor costs. In addition, carrier smart meters can also be used for load management, fault detection, and remote control in power systems.
