Abstract

The invention discloses an icing detection and early warning device for transmission lines, which performs filter edge detection on image information collected by a camera transmitted through a network, and records the coordinates of boundary contour points in the image through binarization processing and boundary tracking. Finally, by comprehensively comparing the coordinates of the boundary points before and after the transmission wire, and using the diameter of the transmission wire to calibrate, the ice thickness of the transmission wire at that time is obtained; data analysis is performed according to the micro-meteorological parameters collected by the data acquisition module, supplemented by the wire within the set time period Tension trend chart and ice thickness change trend chart, combined with the stored historical ice thickness, according to the meteorological parameter conditions that are easy to form ice, the line design ice thickness and the measured ice thickness will affect the ice situation in the next three to five years. The thickness of the ice cover is predicted and an early warning signal is issued. The invention realizes on-line detection of the icing of the power transmission line, and at the same time can perform dynamic early warning, and timely analyze and early warning of the icing information.

Description

technical field [0001] The invention relates to a detection and early warning device, in particular to a power transmission line ice detection and early warning device. Background technique [0002] Transmission lines are particularly prone to freezing in rainy and snowy weather in winter. Once the temperature is low and the thickness of the ice is high, it is easy to break or damage the transmission lines, resulting in greater losses. [0003] Chinese utility model patent CN201420490936 discloses an on-line detection device for transmission line icing, which consists of a sensor unit, a main controller, a communication unit and a power supply unit, the power supply unit is respectively connected to the sensor unit, the main The sensor unit is connected to the sensor unit and the communication unit respectively; the sensor unit includes a tension sensor, a two-dimensional inclination sensor, a three-dimensional ultrasonic wind speed and direction sensor, and a temperature an...
