Embodiment 1

[0039] Such as figure 1 with figure 2As shown, this embodiment discloses a method for automatic identification of wiring status images, and takes the monitoring of wiring status of power distribution cabinets of EMUs as an example to explain in detail how the automatic identification method for wiring status images of the present invention is used for cable wiring status The application process of the acquisition and identification of cable wiring characteristics. The cable connection feature refers to a feature that indicates whether the cable connection state is correct.

[0040] like figure 2 As shown, the method for automatic recognition of wiring status images in this embodiment includes: an image acquisition module and a background module connected by communication; the image acquisition module is mainly responsible for image acquisition of the wiring status of cables, and the background module is Responsible for related image processing, image comparison, compariso...

Embodiment 2

[0050] The difference between this embodiment and Embodiment 1 is that this embodiment compares and marks the accuracy of the cable wiring characteristics, so as to realize rapid fault location, and the background module compares with the standard diagram The accuracy features are annotated on the image.

[0051] Specifically, the wiring feature includes an accuracy feature, and the accuracy is used to indicate whether the wiring cable connected to the cable wiring place is correct, and the background module compares the above comparison image with the standard picture. The background module is provided with an accuracy comparison library containing the wiring cable identification at the cable connection place on the standard diagram, and the outer surface of the wiring cable is provided with an identification that can be collected by the image acquisition module, and the background module passes through The accuracy comparison library is compared with the logo, and the accura...

Embodiment 3

[0054] like figure 2 and 3 As shown, this embodiment discloses a device for automatic identification of wiring state images using the method described in any of the above embodiments, the device includes an image acquisition module connected by communication and a background module; the background module stores information including the correct A standard diagram of cable connection status; the image acquisition module includes an image acquisition device and a fixing device, and the fixing device fixes the image acquisition device and can adjust the position and angle of the image acquisition device.

[0055] like image 3 As shown, the image acquisition device of the device in this embodiment is a pan-tilt camera 2 , and in order to achieve better shooting effects, the device is also provided with a supplementary light 1 . The fixing device includes: a pan-tilt tray 3 and a mechanical arm 4 . Simultaneously, the device is also provided with a tool box 5, which is connect...

Abstract

The invention discloses a cable wiring state image automatic recognition method and device, the method is used for collecting cable wiring state and recognizing cable wiring characteristic, and the device comprises an image acquisition module and a background module which are connected in communication manner; the image acquisition module transmits the collected cable wiring state image to the background module; the background module recognizes the current cable wiring characteristic through comparing the cable wiring state image and a standard image. The device comprises the image acquisition module and the background module which are connected in a communication manner; the background module saves the standard image containing correct cable wiring state; the image acquisition module comprises image acquisition equipment and a fixing device, the fixing device is used for fixing the image acquisition equipment and can adjust the position and the angle of the image acquisition equipment. According to the invention, wiring inspection is performed in objective and non-contact way, and the method and the device have advantages of fixed mode, less external disturbance and the like.

Description

technical field [0001] The invention belongs to the field of remote monitoring, and in particular relates to a method and a device for automatic identification of wiring status images. Background technique [0002] The power distribution cabinet is one of the key main equipment of the electrical equipment of the EMU, and the wiring status of the cables has a significant impact on the operating status of the electrical equipment. When there is a problem with the cable connection in the power distribution cabinet, it will cause abnormal operation of electrical equipment. Therefore, how to quickly detect the connection status of cables in complex power distribution cabinets and judge whether they are correct or not is a major problem encountered by inspectors. The traditional method is to check artificially, which is inefficient and prone to subjective errors due to the limitations of vision in terms of angle and distance. Therefore, an objective, efficient and accurate method...
