  • Publication number: 20220252387
    Abstract: A method for monitoring large deformation of a surrounding rock of a tunnel based on an automatic targeting and ranging system includes: acquiring, by a camera module, a target monitoring image; identifying a center image position in the target monitoring image; performing, by a laser ranging module, an automatic targeting and ranging task according to the center image position; and calculating a deformation offset of each target of left wall targets, right wall targets and a vault target based on an automatic targeting and ranging result corresponding to the target. The method solves the problem that a laser ranging device fails to measure a target at a fixed angle and obtains a real and accurate deformation offset thereby greatly improving the reliability of the large deformation monitoring result of the surrounding rock of the tunnel.

  • Patent number: 11402438
    Abstract: Disclosed is an intelligent on-line diagnosis method for winding deformation of power transformer. When a transformer is subjected to short-circuit shock or transportation collision, transformer windings may undergo local twisting, swelling or the like under the action of an electric power or mechanical force, which is called winding deformation and will cause a huge hidden danger to the safe operation of the power network. Commonly used diagnosis methods for winding deformation are all off-line diagnosis methods, which have the disadvantages that transformers need to be shut down and highly skilled operators are required. The present invention provide an intelligent on-line diagnosis method for winding deformation on the basis of combination of information entropy and support vector machine.
