the positioning module 62 is configured to position the moving wire body protection module 61, and the image capturing unit 2 continuously captures an image of the wire during the movement of the wire body protection module 61.

In the embodiment, when the wind speed received by the wind speed warning module 32 reaches the warning value specified in the wind speed warning module 32, the wind speed warning module 32 sends a signal to the warning transmission module 34 and the image capturing module 21, the wind direction determining module 33 sends the detected wind direction information to the warning transmission module 34, the warning transmission module 34 transmits the received information to the line and sway checking module 41, the image capturing module 21 captures the conducting wire after receiving the information sent by the wind speed warning module 32, and analyzes, compares and judges the captured picture through the comparison module 23, generates the picture information of the swing angle specified by the conducting wire swing exceeding limit setting module 22 into the image limit transmission module 24, and transmits the information to the line and sway checking module 41 through the image limit transmission module 24, and the line and sway checking module 41 determines the swing condition of the conducting wire according to the wind direction and the swing angle of the conducting wire, when the wire generates the conditions of large swing and galloping, the data feedback unit 5 sends warning information to the management end, so that personnel at the management end can know the condition of the wire swing, and when the wire is broken at the later stage, the position where the wire swing gives a warning is subjected to key investigation, and the speed of conducting wire investigation is accelerated.

The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, and the preferred embodiments of the present invention are described in the above embodiments and the description, and are not intended to limit the present invention. The scope of the invention is defined by the appended claims and equivalents thereof.
