Abstract

The utility model relates to a system for on-line monitoring of sag of an overhead transmission line. The system comprises a monitoring terminal, a monitoring base station, and a monitoring center. The monitoring terminal is mounted in the position of a lowest sag point, in a span, of the transmission line needing to be monitored. The monitoring base station is mounted on the top of a tower. An RF data sending module of the monitoring terminal is connected with an RF data receiving module of the monitoring base station through radiofrequency signals. A GPRS data sending module of the monitoring base station is connected with the monitoring center through a mobile communication network. The monitoring terminal utilizes a digital temperature sensor and a laser sensor to acquire data of temperature and clearance to ground of the transmission line, and sends the data to the monitoring center through a wireless network. Thus, the working efficiency is improved; the objective of real-time monitoring is realized; and the safety of the transmission line is guaranteed.
