Abstract

The invention discloses a power transmission line icing detecting and early-warning device. Filtering and edge detection are performed on image information transmitted through a network and acquired by a camera, coordinates of boundary contour points in an image are recorded through binarization processing and boundary tracking, finally, coordinates of boundary points before and behind a power transmission line are compared comprehensively, and the icing thickness of the power transmission line at the moment is obtained through calibration by the aid of the diameter of the power transmission line; data analysis is performed according to micro-meteorological parameters acquired by a data acquisition module, under the assistance of a lead tension change trend diagram and an icing thickness change trend diagram in a set time period, in combination with stored historical icing thicknesses, icing conditions and icing thicknesses in the next three to five days are predicted according to meteorological parameter conditions under which icing is formed easily, the line designed icing thickness and the actually measured icing thickness, and early-warning signals are sent out. With the adoption of the device, online detection is performed on icing of the power transmission line, meanwhile, dynamic early-warning can be realized, and analysis and early-warning can be performed on icing information timely.

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...
