HPLC smart meters are indeed a type of carrier-based smart meter. HPLC technology transmits data via power lines, enabling high-speed, reliable communication that allows smart meters to efficiently collect data and facilitate remote management. 

High-Speed Power Line Communication: HPLC technology utilises existing power lines as a communication medium, transmitting data via high-frequency carrier signals.

- High Data Rates: Compared to traditional low-voltage power line communication (PLC), HPLC achieves significantly higher transmission speeds, reaching hundreds of kbps or even Mbps levels.

- Low Latency: HPLC technology exhibits low latency characteristics, enabling real-time data transmission. This makes it suitable for large-scale data acquisition and remote control applications.

Working Principle

- Data Acquisition: The HPLC smart meter incorporates high-precision sensors to collect real-time electricity consumption data from users.

- Signal Modulation: Acquired data is converted into high-frequency carrier signals via a modulator.

- Power Line Transmission: High-frequency carrier signals are transmitted through power lines to concentrators or cloud servers.

- Data Demodulation: Upon receiving the signals, concentrators or servers restore the original data through demodulators.

- Data Processing: The server processes and analyses the data, generating reports and alert notifications.
