Power transmission line monitoring system integrated with wireless private network communication

Abstract

The invention relates to a power transmission line monitoring system integrated with wireless private network communication. The power transmission line monitoring system comprises a data sensing layer, a network access layer and a master station monitoring layer. The data sensing layer collects current state monitoring data and videos of a power transmission line and uploads the data and the videos after collection is completed. The network access layer accesses a wireless public network to realize communication between the data sensing layer and the master station monitoring layer, monitors the signal strength of the wireless public network in real time, and switches to a 5.8 GHz wireless private network for communication when monitoring that the signal strength of the wireless public network is lower than a threshold. The master station monitoring layer issues an acquisition instruction at regular time, and receives and stores the state monitoring data and videos of the power transmission line. The wireless private network is fused for communication on the basis of the wireless public network, and efficient and reliable operation of the power transmission line monitoring system is ensured.

AI Technical Summary

Problems solved by technology

[0003] At present, the transmission line monitoring system mainly uses 2G / 3G / 4G wireless public network for communication, and some lines are covered with optical fiber communication; however, the transmission network covers a wide area and the geographical environment is complex, and some transmission lines pass through mountains, across rivers, lakes, and cross unmanned At this time, the 2G / 3G / 4G wireless public network signal is poor or even has no signal, which makes the communication intermittent or directly interrupted. It is difficult to reliably transmit the transmission line data collected by the sensor to the main station. 2G / 3G / 4G wireless public network is difficult to meet high bandwidth requirements
