[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Figure 1-2This is a schematic diagram illustrating the composition of a quality monitoring device for shackles used by iron drillers, provided in an embodiment of the present invention. The embodiment of the present invention provides a quality monitoring device for shackles used by iron drillers, comprising:

[0025] The vision module is used to acquire images of the iron driller during the unscrewing process;

[0026] The recognition module is used to process images and obtain the work data of the iron driller;

[0027] The information integration and analysis module is used to determine the quality of the iron driller's upper and lower buckles based on the operation data.

[0028] For example, such as Figure 3-4 As shown, the iron drill bit used in this embodiment of the invention is a double-punch clamp type iron drill bit, including a rotary clamp 1, a first punch clamp 2, and a second punch clamp 3. The rotary clamp 1 is placed in the upper position, and the first punch clamp 2 and the second punch clamp 3 are placed in the lower position. After the first punch clamp 2 and the second punch clamp 3 clamp the lower drill rod 5, the rotary clamp 1 performs the first upper clamping process on the upper drill rod 4. After the first upper clamping process is completed, the iron drill bit moves upward as a whole, so that the second punch clamp 3 clamps the lower drill rod 5, while the first punch clamp 2 performs the second upper clamping process on the upper drill rod 4.

[0029] The vision module may include a camera, which is used to acquire state images of the first punch clamp 2 in the iron drill. The recognition module analyzes multiple state images to determine the rotation angle of the first punch clamp 2.

[0030] In an embodiment of the present invention, the camera may include a top camera 6 and an outer camera 8. The top camera is positioned in front of the screwdriver 1 and the first punching pliers 2 and faces the first punching pliers 2, while the outer camera 8 is positioned directly in front of the driller. During the first and second screw-on processes, the top camera 6 is mainly used for the second detailed screw-on process, while the outer camera 8 takes real-time frontal photos of the driller throughout the screw-on process and uploads them to the recognition module.

[0031] In embodiments of the present invention, the top camera 6 and the outer camera 8 may coexist, or only the outer camera 8 may exist. If only the outer camera 8 exists, it is necessary to ensure that the recognition module can determine the rotation angle of the first punch clamp 2 from the image it captures. Therefore, the presence of only the outer camera 8 places higher demands on the corresponding processing software.

[0032] Furthermore, an identification strip 7 is also provided on the first snap-fit ​​clamp 2. A top camera 6 is suspended between the snap-fit ​​clamp and the first snap-fit ​​clamp 2 and remains fixed. The identification strip 7 is attached to the upper surface of the first snap-fit ​​clamp 2. The identification strip 7 is cuboid and its color differs significantly from that of the first snap-fit ​​clamp 2. During the snap-fit ​​process of the first snap-fit ​​clamp 2, the identification strip 7 rotates with the first snap-fit ​​clamp 2. The top camera 6 captures a real-time position photo of the identification strip 7 and uploads it to the identification module. Preferably, the top camera 6 is positioned directly above the initial position of the identification strip 7, but this embodiment of the invention is not limited to its position, as long as its position ensures that the movement of the identification strip 7 can be captured.

[0033] The outer camera 8 can be a high-definition digital camera, preferably installed directly in front of the drill operator and kept stationary. The outer camera 8 needs to maintain a clear line of sight to the entire drill operator and not interfere with their normal work. After installation, the outer camera 8 needs to be calibrated before use. The purpose of calibration is to determine the relationship between the image and the 3D reality coordinates. After calibration, the outer camera 8 can be used to determine the state of the drill rod, i.e., whether the drill rod is tilted. Furthermore, the outer camera 8 can be positioned anywhere within a certain range in front of the drill operator, not limited to being directly in front of them, as long as it can capture a complete image of the drill rod.

[0034] In one possible embodiment, the operational data includes the rotation angle of the punch clamp, the rotational angular acceleration, whether the applied torque is rotating, whether the drill pipe is tilted, and whether the drill pipe shoulder joint is sealed.

[0035] For example, after the vision module acquires an image, the recognition module first needs to perform A / D conversion on the image, then perform binarization on the digital image, and finally analyze and determine the job data.

[0036] Regarding the rotation angle, the status image acquired by the camera contains information about the identification strip 7. After the identification module performs contour detection on the identification strip 7 in the status image, it obtains multiple positions of the identification strip 7. After performing angle recognition on the multiple positions of the identification strip 7, it determines the rotation angle of the first punch clamp 2.

[0037] Since the image can be acquired by either the top camera 6 or the outer camera 8, the method for recognizing the rotation angle used in this invention differs depending on the image. If the image is acquired by the top camera 6, the recognition module performs contour detection on the recognition strip 7 in the image and calculates the angle based on the overlap of the contours between the two states. Due to the cuboid design of the recognition strip 7, its top view allows for better contour detection and angle calculation. Figure 5 The image shows the top view of the identification strip 7. The left side shows the initial state of the identification strip 7, and the right side shows the state of the identification strip 7 rotated 30°.

[0038] If the image is acquired by the outer camera 8, the recognition module performs contour detection on the main view of the recognition strip 7 in the image. When the first punch clamp 2 rotates clockwise, the rightmost edge is set as the reference position; when the first punch clamp 2 rotates counterclockwise, the leftmost edge is set as the reference position. Let the distance the reference position shifts after the first punch clamp 2 works once be l, the rotation radius of the first punch clamp 2 be r, and the rotation angle of the first punch clamp 2 be α. According to the formula... The rotation angle of the first punch clamp 2 can be calculated.

[0039] Regarding whether the torque is applied and whether the rotation is rotated, after the identification module obtains the torque signal of the driller, it determines whether the torque is applied and whether the first punch clamp (2) rotates based on the determined rotation angle of the first punch clamp 2.

[0040] When the first snap clamp 2 rotates clockwise / counterclockwise, the information analysis module will respond to the snapping / unsnap status. If the driller's cylinder inputs torque, but the first snap clamp 2 does not rotate, the information analysis module will generate a torque deficiency warning.

[0041] Regarding whether the drill pipe is tilted, the image contains information about the upper drill pipe 4 and the lower drill pipe 5. The recognition module performs contour detection on the upper drill pipe 4 and the lower drill pipe 5 in the image. Using the contour of the lower drill pipe 5 as a reference, it determines the angle between the upper drill pipe 4 and the lower drill pipe 5 to determine whether the upper drill pipe 4 is tilted. When the upper drill pipe 4 and the lower drill pipe 5 are tilted, the information integration and analysis module will generate a drill pipe tilt warning. Figure 6 The drill pipe status diagram shown shows the drill pipe in normal condition on the left and in tilted condition on the right.

[0042] Regarding the sealing of the drill pipe joint, the image contains information about the upper drill pipe 4 and the lower drill pipe 5. The recognition module acquires an image of the joint area between the upper drill pipe 4 and the lower drill pipe 5. Based on the area image, it determines whether the joint is within the sealing range. If it is, the recognition module further determines the sealing of the joint based on the determined rotation angle of the first punch clamp 2. When the joint between the upper drill pipe 4 and the lower drill pipe 5 is not sealed, the information integration and analysis module will generate a warning for unsealed joints.

[0043] In one possible embodiment, the image contains information about an identification code set on the drill pipe. After the identification module identifies the identification code, it obtains the corresponding identification information and transmits the identification information to the management system.

[0044] For example, the identification code can be a graphic code or a text code. The graphic code can be a barcode or a QR code, while the text code can be Chinese characters or numbers. The identification code can be laser-engraved onto the drill pipe, and the identification code includes information such as the drill pipe's dimensions and connection sequence. The external camera 8 can track the identification code in real time, and the identification module can recognize the information in the identification code and upload the recognized drill pipe information to the management system.

[0045] In one possible embodiment, after determining the quality of the iron driller's upper and lower buckles, the information integration and analysis module also generates a corresponding quality report.

[0046] For example, after receiving the operation data obtained by the identification module, the information comprehensive analysis module can use this data to assist the intelligent control system of the iron drill in judging the next work situation during the intelligent control process of the iron drill.

[0047] Furthermore, the information integration and analysis module can calculate the rotation speed based on the rotation angle of the punch clamp and export the rotation angle diagram and speed diagram for subsequent system processing. For example... Figure 7 The angle and speed diagrams shown can be used to visually demonstrate the angle and speed conditions.

[0048] In addition to the rotation angle of the punch clamp, whether the torque is applied and the rotation is complete, whether the drill rod is tilted, and whether the drill rod shoulder joint is sealed, the work quality report can also include the iron driller's working time statistics, the status of the buckle and unbuck, whether the rotation speed is exceeded, and whether the drill rod is damaged.

[0049] The top camera 6 and the outer camera 8 capture images and transmit them to the PC system. Both the recognition module and the information analysis module reside within the PC system, which processes the data to determine the quality of the drill bit's connection and disconnection. The PC system then sends this information to the display unit, which shows the connection and disconnection quality and system warnings. The PC system also sends the information to the storage unit, which stores the drill bit's current work data, historical work data, and work quality reports. Finally, the PC system sends the information to the intelligent drill bit system, using the work quality analysis report to assist the intelligent drill bit system in achieving intelligent control.

[0050] like Figure 8 As shown, the usage process of the monitoring system in this invention is as follows:

[0051] Upon opening the system's user management interface, users can manually input information such as the province, city, and county where the drilling platform is located, the platform name, and the operator's number. Once the driller begins work, the camera captures real-time images and uploads them to the recognition module. The recognition module analyzes the images to determine the rotation angle of the punch pliers and whether the drill pipe is tilted. During the driller's work, the display unit shows the real-time rotation angle of the punch pliers and whether the drill pipe is tilted, and displays the entire work process data in real-time as a visualized digital curve. The system records and analyzes the large amount of data generated during the driller's work process and generates a work quality report in chronological order.

[0052] Although preferred embodiments of the invention have been described, those skilled in the art, upon learning the basic inventive concept, can make other changes and modifications to these embodiments. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the invention.

[0053] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
