AI Technical Summary

Technical Problem

Traditional intelligent converged terminals and low-voltage sensing devices are susceptible to electromagnetic interference when communicating on power lines, which can lead to signal distortion or attenuation. Furthermore, multiple devices transmitting data in the same frequency band are prone to conflicts, resulting in transmission delays or data loss.

Method used

A synchronous time synchronization device is used to provide the same reference time signal for all power collectors and intelligent fusion terminals, enabling time-sharing data transmission. A zero-crossing detection circuit monitors the carrier communication signal strength in real time and automatically switches to wireless communication in case of interference, ensuring the continuity and accuracy of data transmission.

Benefits of technology

It effectively solves the problems of signal distortion and data conflict caused by electromagnetic interference, and improves the stability of the system and the reliability of data transmission.

Abstract

This utility model relates to the field of power data transmission technology, specifically a collaborative interconnection system between an intelligent fusion terminal and data collectors. The system includes an intelligent fusion terminal, a synchronization time device, and several power collectors. The intelligent fusion terminal and the power collectors are connected via power lines. The synchronization time device is wirelessly connected to both the intelligent fusion terminal and each power collector. By transmitting the same reference time signal to all power collectors and the intelligent fusion terminal through the synchronization time device, multiple power collectors can transmit data collected at the same time in a time-sharing manner. The intelligent fusion terminal uses a zero-crossing monitoring circuit to detect the signal strength of the carrier communication in real time and automatically switches to the wireless communication module, ensuring the continuity and accuracy of data transmission.
