Embodiment Construction

[0061] In this example, if Figure 5 As shown, a wire galloping monitoring method based on concentric circle detection is to install a concentric circle shape on the wire and identify the concentric circle structure in the shape, and then calculate the center coordinates to grasp the wire galloping track, maximum amplitude, Information such as the main frequency keeps the transmission wire within the monitoring range. Once there is an abnormal situation in the wire galloping, it can be reported in time. Specifically, the following steps are included:

[0062] Step 1, such as figure 1 As shown, fix the concentric circle shape on the power transmission wire, and it is recommended to install it at the sag point of the wire; the marker is a black and white concentric circle, such as figure 2 The first kind of concentric circles shown, such as image 3 The second type of concentric circles shown;

[0063] Step 2. Install a video camera on the power tower or the base of the towe...

Abstract

The invention discloses a conductor galloping monitoring method based on concentric circle detection. The method comprises the steps: fixing a concentric circle-shaped object on a power transmission conductor, enabling a camera to collect a video image containing the concentric circle-shaped object in real time, and calculating the central coordinates of the concentric circle-shaped object throughthe recognition of concentric circles in the image; the conductor galloping track can be obtained by recording center coordinate changes, and the maximum amplitude of conductor galloping and the mainfrequency of galloping are further calculated, so that the effect of dynamically monitoring the conductor galloping condition in real time is achieved.

Description

technical field [0001] The method of the invention belongs to the field of target detection on power transmission wires, specifically a wire galloping monitoring method based on concentric circle detection, thereby obtaining the galloping situation of power transmission wires. Background technique [0002] Galloping of transmission line conductors is a serious disaster that endangers the safe and stable operation of transmission lines. Galloping is a low-frequency, large-scale self-excited vibration generated by eccentric icing on conductors under wind excitation. Galloping will cause tripping, damage to hardware and insulators, Serious accidents such as broken strands and broken wires, loose and falling tower bolts, damaged tower materials, damaged foundations, and even collapsed towers seriously threaten the safe operation of the power grid. [0003] Existing galloping monitoring methods are mainly environmental monitoring sensor networks based on wireless sensing technolo...
