Embodiment 1

[0047] figure 1 and figure 2 A schematic structural diagram of the cable icing monitoring system provided by Embodiment 1 of the present invention is shown, and the details are as follows:

[0048] The cable icing monitoring system includes a plurality of sensors 100 , a plurality of image acquisition and processing devices 200 , a plurality of information transfer nodes 300 , a server 400 and a plurality of maintenance personnel terminals 500 . The sensors 100 correspond to the image acquisition and processing devices 200 one by one, and the information transfer node 300 corresponds to a plurality of the sensors 100 and a plurality of the image acquisition and processing devices 200 .

[0049]The sensor 100 is arranged in the middle of the cable 502 between two adjacent utility poles 501 for detecting the real-time height of the cable. The plurality of sensors 100 respectively correspond to the cables 502 between the plurality of utility poles 501, and correspond to a sens...

Embodiment 2

[0073] Corresponding to the power line monitoring system described in the above embodiments, image 3 The power line monitoring method provided by the embodiment of the present invention is shown, and the details are as follows:

[0074] Step S101, detecting the real-time height of the cable through sensors; the plurality of sensors correspond to the cables between the plurality of utility poles respectively, and correspond to a sensor identifier representing position information.

[0075] Wherein, a sensor identifier corresponds to a geographic location, and is used to represent the location where the sensor is set. The sensor 100 may be a height sensor for measuring the height of the sensor 100 to the ground. Wherein, each sensor 100 corresponds to a first threshold, and the first threshold corresponds to the critical height of the cable to the ground under normal conditions, and if it is smaller than the first threshold, the cable may be covered with more ice.

Abstract

The invention is applicable to the technical field of power and provides a cable icing monitoring method and system. The method comprises the following steps: detecting a real-time height of the cableby virtue of a sensor, acquiring a current image of the cable by an image acquisition processing device when a corresponding sensor detects that the real-time height of the cable is less than a firstthreshold, and determining an icing thickness of the cable according to the current image; receiving the icing thickness determined by the image acquisition device by an information transfer node, and transmitting the real-time height of the cable, the icing thickness and a sensor identifier to a server when the icing thickness is more than a second threshold; and combining current weather information corresponding to the sensor identifier by the server, judging the icing conditions of the cable, and transmitting judgment results to a maintenance personnel terminal. Therefore, the cable icingconditions can be detected in real time, hidden danger existing in the cable can be discovered in time, and related maintenance personnel can be notified in time.

Description

technical field [0001] The invention belongs to the technical field of electric power, and in particular relates to a method and system for monitoring cable icing. Background technique [0002] High-altitude cables are easily affected by the environment, especially in winter, which may be affected by icing, which may cause cable damage and affect the safety of the line. At present, the icing detection of high-altitude cables is usually carried out by manual observation, and manual observation has a great chance and time interval, and the hidden dangers of cables cannot be found in time. Security, reliability and stability have a critical impact. Contents of the invention [0003] In view of this, the embodiments of the present invention provide a cable icing monitoring method and system to solve the problems in the prior art that human observation of cable icing thickness has contingencies and time intervals, and hidden dangers of cables cannot be found in time. [0004]...
