Definitions
- the present invention relates to a maintenance device control system for controlling and maintaining maintenance devices, a maintenance device control method, and a program.
- Patent Document 1 an in-facility inspection system using an unmanned aerial vehicle capable of inspecting equipment installed in a facility even if workers do not go to the site.
- the present invention analyzes an image captured by a drone camera, determines a defect of an object, and controls maintenance equipment to pinpoint maintenance to an object determined to be defect. It is an object of the present invention to provide a maintenance device control system, a maintenance device control method, and a program.
- the present invention provides the following solutions.
- An invention for controlling a maintenance device to perform maintenance, comprising: an image acquisition unit for acquiring an image captured by a drone; and analyzing the image to obtain an object Apparatus for controlling the maintenance device so as to maintain the defects of the subject at the estimated position, and the position determining means for estimating the position of the subject determined to be defective
- a maintenance device control system comprising: control means.
- An invention is a maintenance device control method for controlling a maintenance device to perform maintenance, comprising: an image acquisition step of acquiring an image captured by a drone; analyzing the image; Apparatus for controlling the maintenance device so as to maintain the defects of the subject at the estimated position, and the position determining step of determining the position of the subject determined to be defective; And a control step of controlling the maintenance device.
- the invention according to the first aspect includes an image acquisition step of acquiring an image captured by a drone, a defect determination step of analyzing the image and determining a defect of the object, and a position of the object determined as the defect. And a device control step of controlling the maintenance device to maintain the defect of the subject at the estimated position.
- FIG. 1 is a schematic diagram of a maintenance device control system.
- FIG. 2 is an example of a line determined to be defective.
- the maintenance device control system of the present invention is a system for controlling a maintenance device to perform maintenance on an object.
- FIG. 1 is a schematic view of a maintenance device control system according to a preferred embodiment of the present invention.
- the maintenance device control system includes an image acquisition unit, a defect determination unit, a position estimation unit, and a maintenance device control unit, which are realized by the control unit reading a predetermined program.
- drone control means may be provided similarly. These may be application based, cloud based or otherwise. Each means described above may be realized by a single computer or may be realized by two or more computers (for example, in the case of a server and a terminal).
- An image acquisition means acquires the image imaged with the camera of the drone.
- the image may be a moving image or a still image.
- the camera may be any camera provided in the drone, either a digital camera or a camera of a smartphone. Real-time images are preferable for real-time maintenance.
- the determination means analyzes the image to determine the defect of the subject.
- Machine learning may improve the accuracy of image analysis. For example, machine learning is performed using past images as teacher data. For example, as shown in FIG. 2, image failure may be determined by image analysis. Of course, not only a track but also a defect in a building, a road, a terminal, or the like may be determined. For example, as compared with the field worker determining the defect while walking near the track, by analyzing the image captured by the drone to determine the defect, significant efficiency can be achieved.
- the defect determination unit may analyze the image and determine that the subject is defective if the size satisfies a predetermined condition. For example, if the size of the track is smaller or larger than the reference value, there is a risk of derailment, which is dangerous. In this case, it is determined that the line is defective.
- the defect determination unit may analyze the image and determine that the subject is defective if the color satisfies a predetermined condition. For example, if the color of the line is lighter or darker than the reference value, it may be dangerous if the line is broken due to rust, which may lead to derailment. In this case, it is determined that the line is defective.
- the defect determining means may analyze the image and determine that the subject is defective if the shape satisfies a predetermined condition. For example, if the size of the track is smaller or larger than the reference value, there is a risk of derailment, which is dangerous. In this case, it is determined that the line is defective.
- the position estimation means estimates the position of the subject determined to be defective.
- the position of the subject determined to be defective can be inferred from the GPS provided in the drone, the shooting height in the drone, the shooting angle, and the shooting direction.
- the position of the subject determined to be poor in breeding is the latitude and longitude obtained by adding Htan ⁇ in consideration of the shooting direction to the latitude and longitude of GPS.
- the maintenance device control means controls the maintenance device to maintain the defect of the subject at the estimated position.
- the maintenance equipment of the track is controlled to maintain the track at the estimated position.
- a maintenance dedicated drone may be controlled to maintain the track at the inferred position. Efficient use of maintenance can be achieved by selectively using the imaging-specific drone and the maintenance-specific drone.
- the drone control means controls the drone to fly again and image again at the estimated position. For example, since there is no possibility that the determination of the defect is an erroneous determination, the drone is re-flyed and photographed again to care for the erroneous determination. By analyzing the image captured again, it is possible to double check the determination of the defect. [Description of operation]
