Description

Concrete utility pole horizontal crack self-diagnosis system

[0001] The present invention relates to a self-diagnosis system for horizontal cracks in a concrete utility pole, and more particularly, to a self-diagnosis system for horizontal cracks in a concrete utility pole that can determine whether a horizontal crack has occurred in a concrete utility pole and inform a user of the same.

[0002] Typically, concrete utility poles are partially buried underground and are composed of cantilever-shaped structural members, and the weight of wires and various transmission and distribution-related accessories is installed on the top of the utility pole to act as a load.

[0003] The load acts mostly as an axial compressive load on the utility pole, but when the horizontal arrangement angle of the power cable changes or the transmission and distribution equipment is installed to one side, it acts as an eccentric load and acts as a moment load on the cantilever member.

[0004] Due to the action of this eccentric load, the largest moment load is applied from the ground surface location where the utility pole is embedded in the ground to a certain depth, which causes bending of the utility pole, and in the case where an excessive moment load occurs or a long-term continuous moment load occurs, there is a problem in that a horizontal bending crack occurs on the opposite side of the utility pole where the bending occurs.

[0005] The present invention was created to solve such problems, and the purpose of the present invention is to provide a self-diagnosis system for horizontal cracks in concrete utility poles that can determine whether horizontal cracks have occurred in concrete utility poles and inform the user of the same.

[0006] In order to achieve the above object, the present invention provides a self-diagnosis system for horizontal cracks in a concrete utility pole, comprising: a crack detection device installed on the concrete utility pole and generating detection information; a crack detection server receiving detection information from the crack detection device, analyzing the detection information using a pre-learned artificial intelligence algorithm, and determining whether or not the concrete utility pole has a horizontal crack; and a user terminal receiving a crack occurrence alarm from the crack detection server.

[0007] In addition, the crack detection device is characterized by including a crack detection sensor unit installed on the outer surface of the concrete utility pole and generating detection information; a crack detection control unit receiving detection information from the crack detection sensor unit, storing the detection information, and transmitting the detection information to the crack detection server; and a sensor cable wired inside the concrete utility pole and connecting the crack detection sensor unit and the crack detection control unit to each other.

[0008] In addition, the crack detection sensor unit is characterized by including a sensor body unit that is installed in close contact to surround a crack or a portion expected to have a crack on the outer surface of the concrete utility pole; and a plurality of sensor detection units that are installed on the side of the sensor body unit to generate detection information.

[0009] In addition, the sensor detection unit is characterized by having eight strain gauges installed on the side of the sensor body, and when a longitudinal bending moment of a concrete utility pole is transmitted to the sensor body, the sensor generates detection information by measuring the strain transmitted to the sensor body.

[0010] In addition, the crack detection server is characterized by including an algorithm learning unit that learns a plurality of artificial intelligence algorithms through a learning dataset, and selects and stores the artificial intelligence algorithm with the highest performance among the plurality of artificial intelligence algorithms through a verification and test dataset; an algorithm adoption unit that adopts one of the artificial intelligence algorithms stored in the algorithm learning unit when detection information is transmitted from the crack detection device; an algorithm prediction unit that analyzes the detection information through the algorithm adopted by the algorithm adoption unit and transmits crack alarm information to the user terminal when it is determined to be a crack; and an algorithm re-learning unit that re-learns the artificial intelligence algorithm through the detection information analysis result performed by the algorithm prediction unit.

[0011] In addition, the algorithm learning unit is characterized in that it uses a Bayesian Optimizer technique that optimizes hyperparameters of artificial intelligence algorithms to measure at least one of sensitivity, specificity, accuracy, PPV (positive predictive value), NPV (negative predictive value), and AUC (area under the ROC (receiver operating characteristic)) scores of multiple artificial intelligence algorithms, and selects and stores the artificial intelligence algorithm with the highest performance.

[0012] The self-diagnosis system for horizontal cracks in a concrete utility pole according to the present invention can improve the efficiency of managing concrete utility poles by determining whether horizontal cracks have occurred in a concrete utility pole and informing the user of the same.
