[0010] A vertical pull-up intelligent standard counting method for a pull-up auxiliary training device comprises the following steps:
[0011] S1, start;
[0012] S2. Capturing an image of the user's pull-up area through a camera, finding the user's figure in the image of the pull-up area using a human figure detection algorithm, determining whether the user is in an initial position with arms hanging straight in the image of the user's figure, and performing a pull-up forward and backward judgment. If the judgment is passed, the pull-up preparation is completed;
[0013] S3. Enable the pull-up standard counting service. Based on the collected user image, determine the nose and chin detection points in the head outline using computer vision object detection. Obtain the initial positions of the nose and chin detection points, and perform pull-up standard counting analysis and judgment. The specific judgment method is as follows:
[0014] When at least one of the movement positions of the nose or chin detection points in the head outline is lower than the horizontal bar and the soles of the feet are suspended in the air, it is determined to be a standard pull-up behavior, and the auxiliary force of the pull-up training device is zero;
[0015] If at least one of the movement positions of the nose or chin detection points in the head silhouette is lower than the crossbar and the soles of the feet are in contact with the pedals, it is determined to be a pull-up with auxiliary force;
[0016] S4. User's Standard Pull-Up Count: The work done by the user in the standard pull-up minus the assist force of the assist gear used is used to obtain the actual work done by the user in the pull-up. If the work done by the user in multiple pull-ups is greater than the work done by the user in a single standard pull-up, it is considered a standard pull-up behavior, and the number of standard pull-ups of the user is updated;
[0017] S5. Display the user's standard number of pull-ups until the user finishes doing pull-ups.
[0018] Compared with the prior art, the present invention has the following beneficial effects:
[0019] After the user stands on the foot pedal, a camera near the top of the intelligent all-in-one machine captures the user's face. The facial recognition module identifies the facial data, and the data processor searches the database module for the corresponding vertical pull-up training data. The controller then activates the servo motor to rotate the threaded rod and push the adjustment frame to move. The position of the adjustment frame is adjusted according to the corresponding vertical pull-up training data, that is, the auxiliary force value of the cylinder is adjusted. If there is no corresponding vertical pull-up training data, the servo motor is activated to rotate the threaded rod, and the threaded rod drives the adjustment frame to the position where the auxiliary force of the cylinder is maximum. When the user's foot is not on the unlocking pedal, the self-locking component fixes the foot pedal to the bottom of the support frame. The camera near the bottom of the intelligent all-in-one machine captures the image of the user's foot not in contact with the unlocking pedal and transmits it to the data processor. At this time, when the user grasps the gripping bar and applies force to do a vertical pull-up, the camera captures the image of the user's chin being higher than the gripping bar, which is recorded as a standard vertical pull-up and displayed on the touch screen. When the user is on the board, the self-locking assembly releases the foot pedal's position. The camera captures an image of the user's foot overlapping the unlocking pedal and transmits it to the data processor. At this point, when the user grasps the grip bar and applies force to perform a vertical pull-up, the camera captures an image of the user's chin at a height above the grip bar. The difference between the work performed in a standard vertical pull-up and the assist force provided by the camera is calculated, and the resulting value represents the work actually generated by the user performing the vertical pull-up. When the work actually performed by the user during multiple pull-ups exceeds the work performed in the standard vertical pull-up, it is converted into one standard number of pull-ups and displayed on the touch screen. The linear guide guides the foot pedal's vertical movement, resulting in a more standardized pull-up training motion compared to existing techniques. Pull-ups performed with and without the assistance of the pull-up assisting training device are counted separately, enabling intelligent and standardized recording of qualified pull-ups, facilitating student pull-up testing and training within schools.

The top of the support frame 1 is fixedly connected to a force-bearing member for adjusting the height of the pull-up horizontal bar by the user. The force-bearing member includes two hanging frames 8 fixedly connected to the top of the support frame 1. Grab rods 10 are hung on the two hanging frames 8. The height adjustment is completed by placing the grab rods 10 at different heights inside the hanging frames 8 according to user needs. Two unlocking pedals 6 are inserted in the foot pedal 5, and a self-locking component 9 for limiting the unlocking pedal 6 is provided at the bottom;
[0036] The top and bottom of the intelligent all-in-one machine 11 are both equipped with cameras 14. A face recognition module, a database module, a controller, a data processor, and a touch screen 13 are fixedly connected to the intelligent all-in-one machine 11. The camera 14, the face recognition module, the database module, the controller, and the touch screen 13 are all connected to the data processor signal. The linear guide 2 guides the foot pedal 5 to move in the vertical direction. Compared with the existing technology, the pull-up training movements performed by the user are more standardized. At the same time, the two situations of the user performing pull-up training with the assistance of the pull-up auxiliary training device and performing pull-up training without the assistance of the pull-up auxiliary training device are counted separately. The number of pull-ups that meet the standards is intelligently and standardizedly recorded, which is helpful for pull-up testing and training of students within the campus;
[0037] See also Figure 2 、 Figure 5In this embodiment, the self-locking component 9 includes a limiting column slidably set on the foot pedal 5 and a limiting hole 92 opened on the support frame 1. The limiting column is inserted into the limiting hole 92. A mounting groove is opened on the lower end surface of the foot pedal 5. One end of the limiting column slides in the mounting groove. A fixed column is fixedly installed on one end of the limiting column. A support rod is rotatably set on the fixed column. A V-shaped rod 95 is rotatably set on the support rod. The V-shaped rod 95 is connected to the support rod through a rotating shaft. A mounting block 901 is fixedly installed at the bottom end of the mounting groove. The middle part of the V-shaped rod 95 is rotatably set on the mounting groove. On the mounting block 901, a connecting unit 96 is provided between the foot pedal 5 and the V-shaped rod 95. Two connecting springs are provided between the rotating shaft and the mounting groove. The connecting unit 96 includes a top rod 962 fixedly mounted on the lower end surface of the foot pedal 5. A support rod 51 is fixedly mounted on the mounting groove. A balance rod 961 is rotatably connected to the support rod 51. The top rod 962 is slidably provided on the balance rod 961. The balance rod 961 is located at the upper end of the V-shaped rod 95 and contacts it. An elastic member is provided between the unlocking pedal 6 and the support rod 51. The elastic member adopts a spring commonly used in the prior art.
[0038] It should be noted that when the unlocking pedal 6 is pressed and moves downward, the balancing rod 961 is squeezed by the push rod 962. During the squeezing process, the push rod 962 will slide downward along the balancing rod 961, and the balancing rod 961 will squeeze the V-shaped rod 95. The middle part of the V-shaped rod 95 rotates along the support rod, and the end of the V-shaped rod 95 away from the balancing rod 961 will be knocked up. During the knocking process, the V-shaped rod 95 will pull up the support rod, and the support rod will then pull the limiting column. During this process, the rotating shaft will stretch the corresponding connecting spring, and the limiting column will disengage from the limiting hole 92, thereby releasing the limit of the foot pedal 5;
[0039] When the unlocking pedal 6 on the foot pedal 5 is not pressed, the unlocking pedal 6 will return to its initial position through the setting of the elastic member. At this time, the connecting spring will retract, which will drive the limiting column to slide along the foot pedal 5 until it is inserted into the corresponding limiting hole 92. At this time, the foot pedal 5 is fixed and cannot be moved.
[0040] See also Figure 1 、 Figure 3 In this embodiment, the linear guide 2 includes a fixed plate 201, a guide rod 202, a slider 203, a shock-absorbing spring 204 and a damper 205. The fixed plate 201 is fixedly connected to one side of the support frame 1, one end of the guide rod 202 is fixedly connected to the fixed plate 201, and the other end of the guide rod 202 is fixedly connected to the support frame 1. A guide hole for the guide rod 202 to pass through is opened in the slider 203, the shock-absorbing spring 204 is plugged into the guide rod 202, the damper 205 is fixedly connected to the shock-absorbing spring 204, and one side of the slider 203 is fixedly connected to the foot pedal 5. The slider 203 moves along the guide direction of the guide rod 202, so that the foot pedal 5 can move vertically.
[0041] It should be noted that a servo motor 16 is fixedly connected to one side of the tripod 3, and a threaded rod 15 is fixedly connected to the driving end of the servo motor 16. A threaded through hole compatible with the threaded rod 15 is opened in the adjusting frame 7. The controller is electrically connected to the servo motor 16. The servo motor 16 is started by the controller to rotate the threaded rod 15 and push the adjusting frame 7 to move. The position of the adjusting frame 7 is adjusted according to the corresponding vertical pull-up training data. When the adjusting frame 7 is close to the position of the servo motor 16, the auxiliary force value that the cylinder 4 can provide is the smallest. When the adjusting frame 7 is farthest from the position of the servo motor 16, the auxiliary force value that the cylinder 4 can provide is the largest. In this way, the position change of the adjusting frame 7 is adjusted to achieve the purpose of adjusting the auxiliary force that the cylinder 4 can provide.
[0042] It should be noted that when the cylinder 4 pushes the tripod 3 to provide auxiliary force for the foot pedal 5 , the tripod 3 will slide inside the docking port to avoid interfering with the movement of the foot pedal 5 .
[0043] A vertical pull-up intelligent standard counting method for a pull-up auxiliary training device comprises the following steps:
[0044] S1, start;
[0045] S2. Capturing an image of the user's pull-up area through a camera, finding the user's figure in the image of the pull-up area using a human figure detection algorithm, determining whether the user is in an initial position with arms hanging straight in the image of the user's figure, and performing a pull-up forward and backward judgment. If the judgment is passed, the pull-up preparation is completed;
[0046] S21. After the user stands on the footrest 5, the camera 14 near the top of the intelligent all-in-one machine 11 captures the user's face. The facial recognition module identifies the facial data, and the data processor searches the database module for the corresponding vertical pull-up training data. The controller then activates the servo motor 16 to rotate the threaded rod 15 and push the adjustment frame 7 to move. The position of the adjustment frame 7 is adjusted according to the corresponding vertical pull-up training data, that is, the auxiliary force value of the cylinder 4 is adjusted. If there is no corresponding vertical pull-up training data, the servo motor 16 is activated to rotate the threaded rod 15, and the threaded rod 15 drives the adjustment frame 7 to move to the position where the auxiliary force of the cylinder 4 is the greatest.
[0047] S3. Enable the pull-up standard counting service. Based on the collected user image, determine the nose and chin detection points in the head outline using computer vision object detection. Obtain the initial positions of the nose and chin detection points, and perform pull-up standard counting analysis and judgment. The specific judgment method is as follows:
[0048] When at least one of the movement positions of the nose or chin detection points in the head outline is lower than the horizontal bar and the soles of the feet are suspended in the air, it is determined to be a standard pull-up behavior, and the auxiliary force of the pull-up training device is zero;
[0049] If at least one of the movement positions of the nose or chin detection points in the head silhouette is lower than the crossbar and the soles of the feet are in contact with the pedals, it is determined to be a pull-up with auxiliary force;
[0050] S31. When the user's foot is not on the unlocking pedal 6, the self-locking assembly 9 secures the foot pedal 5 to the bottom of the support frame 1. The camera 14 near the bottom of the intelligent all-in-one device 11 captures an image of the user's foot not in contact with the unlocking pedal 6 and transmits it to the data processor. At this time, when the user grasps the gripping bar 10 and applies force to perform a vertical pull-up, the camera 14 captures an image of the user's chin being above the gripping bar 10. This is recorded as a standard vertical pull-up and displayed on the touch screen 13.
[0051] S32. When the user's foot steps on the unlocking pedal 6, the self-locking component 9 will release the fixation of the foot pedal 5. The camera 14 will capture the overlapping image of the user's foot and the unlocking pedal 6 and transmit it to the data processor. At this time, when the user grasps the gripping rod 10 and applies force to do a vertical pull-up, the camera 14 will capture the image of the user's lower jaw at a height higher than the gripping rod 10. The difference between the work done by the standard vertical pull-up in S2 and the auxiliary force provided by the camera 14 is calculated. The obtained value is the work actually generated by the user doing the vertical pull-up. When the work actually done by the user doing multiple pull-ups is ≥ the work done by the standard vertical pull-up, it is converted into one standard number of pull-ups and displayed on the touch screen 13.
[0052] S4. User's Standard Pull-Up Count: The work done by the user in the standard pull-up minus the assist force of the assist gear used is used to obtain the actual work done by the user in the pull-up. If the work done by the user in multiple pull-ups is greater than the work done by the user in a single standard pull-up, it is considered a standard pull-up behavior, and the number of standard pull-ups of the user is updated;
[0053] S5. Displaying the user's standard number of pull-ups until the user finishes doing pull-ups;
[0054] S51. Display the standard number of pull-ups recorded in step S31 or step S32 using step S4 on the touch screen 13.
[0055] When students are taking a pull-up test on campus, the operation in step S2 is used for counting. When students are doing pull-up training, the operation in step S3 is used for counting. The users mentioned in this technical solution can be students, teachers, and other people who need pull-up auxiliary training.
[0056] Working principle: After the user stands on the foot pedal 5, the camera 14 near the top of the intelligent all-in-one machine 11 captures the face image, and the facial recognition module recognizes the facial data. The data processor searches for the corresponding vertical pull-up training data recorded in the database module, and then the controller starts the servo motor 16 to rotate the threaded rod 15 and push the adjustment frame 7 to move. The position of the adjustment frame 7 is adjusted according to the corresponding vertical pull-up training data, that is, the auxiliary force value of the cylinder 4 is adjusted. If there is no corresponding vertical pull-up training data, the servo motor 16 is started to rotate the threaded rod 15, and the threaded rod 15 drives the adjustment frame 7 to move to the position where the auxiliary force of the cylinder 4 is the largest; when the user's foot is not on the unlocking pedal 6, the self-locking component 9 fixes the foot pedal 5 to the bottom of the support frame 1, and the camera 14 near the bottom of the intelligent all-in-one machine 11 captures the image of the user's foot not in contact with the unlocking pedal 6 and transmits it to the data processor. At this time, when the user grasps the gripping rod 10 and applies force to do a vertical pull-up, the camera 14 captures the user's jaw. When the user's foot steps on the unlocking pedal 6, the self-locking assembly 9 releases the position of the foot pedal 5. The camera 14 captures the overlapping image of the user's foot and the unlocking pedal 6 and transmits it to the data processor. At this time, when the user grasps the gripping rod 10 and applies force to perform a vertical pull-up, the camera 14 captures the image of the user's chin at a height higher than the gripping rod 10. The difference between the work performed in the standard vertical pull-up in S2 and the auxiliary force provided by the cylinder 4 is calculated. The obtained value is the work actually generated by the user performing the vertical pull-up. When the work actually performed by the user in multiple pull-ups is greater than the work performed in the standard vertical pull-up, it is converted into one standard number of pull-ups and displayed on the touch screen 13. The two situations of the user performing pull-ups with the assistance of the pull-up auxiliary training device and without the assistance of the pull-up auxiliary training device are counted separately, and the number of pull-ups that meet the standard is intelligently and standardizedly recorded.
[0057] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be included therein.

7. A vertical pull-up intelligent standard counting method based on the vertical pull-up intelligent standard counting pull-up auxiliary training device according to any one of claims 1 to 6, characterized in that: The following steps are involved: S1, start; S2. Capturing an image of the user's pull-up area through a camera, finding the user's figure in the image of the pull-up area using a human figure detection algorithm, determining whether the user is in an initial position with arms hanging straight in the image of the user's figure, and performing a pull-up forward and backward judgment. If the judgment is passed, the pull-up preparation is completed; S3. Enable the pull-up standard counting service. Based on the collected user image, determine the nose and chin detection points in the head outline using computer vision object detection. Obtain the initial positions of the nose and chin detection points, and perform pull-up standard counting analysis and judgment. The specific judgment method is as follows: When at least one of the movement positions of the nose or chin detection points in the head outline is lower than the horizontal bar and the soles of the feet are suspended in the air, it is determined to be a standard pull-up behavior, and the auxiliary force of the pull-up training device is zero; If at least one of the movement positions of the nose or chin detection points in the head silhouette is lower than the crossbar and the soles of the feet are in contact with the pedals, it is determined to be a pull-up with auxiliary force; S4. User's Standard Pull-Up Count: The work done by the user in the standard pull-up minus the assist force of the assist gear used is used to obtain the work done by the user in the pull-up. If the work done by the user in multiple pull-ups is greater than the work done by the user in a single standard pull-up, it is considered a standard pull-up and the number of standard pull-ups of the user is updated. S5. Display the user's standard number of pull-ups until the user finishes doing pull-ups.
