Description

Technical Field

[0001] This utility model relates to the field of intelligent monitoring system technology, and in particular to the module structure of an intelligent detection system used for barbell training. Background Technology

[0002] With the deepening implementation of the national strategies of "Fitness for All" and "Healthy China," the concepts of scientific exercise and healthy living have taken root in people's hearts. Under this development trend, real-time body posture assessment technology, due to its advantages of accuracy, dynamism, and visualization, has shown great application potential in fields such as rehabilitation medicine, sports medicine, and sports training.

[0003] However, traditional barbell training movement assessment relies excessively on on-site guidance from professional coaches, which has significant limitations: the assessment process is heavily influenced by the coach's personal experience and subjective judgment; coaches struggle to quantify the details of the movements, relying only on visual observation to provide qualitative descriptions, failing to accurately capture key parameters such as barbell trajectory and joint angle changes, thus hindering scientific evaluation of training effectiveness. Professional coaching services are also limited by time and space, making it difficult to meet the training needs of the general public in non-professional settings. Improper barbell movements not only reduce training efficiency but also increase the risk of joint injuries and muscle strains, severely restricting the safety and scientific rigor of barbell training.

[0019] Data acquisition module 1, vision device 11, motion sensing device 12, angle adjustment device 13, system processing module 2. Detailed Implementation

[0020] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0021] This utility model discloses a module structure for an intelligent monitoring system for barbell training, such as... Figure 1As shown, the system includes a data acquisition module 1, a system processing module 2, and an interaction module. The data acquisition module 1 mainly includes a vision device 11 and a motion sensing device 12. The vision device 11 is installed to cover the shooting range of the trainee's activity space. As shown in the figure, the vision device 11 is set above the trainee opposite them. It is stably erected by a steel frame. It can be fixed or adjusted to accommodate people of different heights, different barbell training movements, and different detection and analysis parts. It can be further erected by setting an adjustment device structure, such as a height adjustment device (not shown in the figure) that can be raised and lowered. The height adjustment device can be connected to the system processing module 2 to transmit electrical signals for control and drive, and can realize automatic height adjustment according to system settings and intelligent recognition. In addition, the vision device 11 can be mounted via an angle adjustment device 13 that allows for pitch adjustment, such as a one-dimensional or two-dimensional motorized gimbal, preferably a two-dimensional motorized gimbal. Besides pitch adjustment, it can also adjust the shooting direction, which is more conducive to intelligent automatic system calculation and positioning adjustment based on the trainee's position. This provides a wider shooting angle for the trainee, facilitates angle adjustment, and enhances the intelligence of barbell training monitoring. Communication can be via wired connection (such as UART serial communication) or wireless communication, enabling automatic angle adjustment based on system settings and intelligent recognition. The lifting and pitch adjustment of the adjustment device structure can also be configured to form an integrated motorized gimbal module. After testing, the pitch angle adjustment range of the vision device 11 is preferably within 30° upward and 40° downward, reducing background factors that affect visual monitoring, such as people or objects other than the trainee. It also allows for spatial adjustment to accommodate various barbell training exercises, reducing unnecessary visual shooting range. In addition, the vision device 11 is mounted at a height higher than the trainee's height, and its pitch angle adjustment range of 15°-75° below the horizontal can also achieve the aforementioned effect. It can be used for monitoring various barbell training exercises without frequent adjustments. In this embodiment, the vision device 11 preferably uses a color depth camera (such as the existing product model name Azure Kinect DK), which provides a wider shooting angle for the user, is easy to adjust, and can record color images of the human body and barbell bar, as well as three-dimensional point cloud data of the human body and barbell bar, for subsequent data calculation. It can be connected to the system processing module 2 via a USB interface, which is conducive to high-speed transmission of image data and stable data transmission.

[0022] The activity sensing device 12 is used to detect the angular velocity and / or acceleration at the set node position on the trainee's body. The set node position can be any node in the body where the height, angle, and velocity change during barbell training, such as various joint points, body segmentation height parts (head, shoulder height), etc. The module structure in this embodiment includes head sensors positioned on the trainee's head, shoulder sensors on the trainee's shoulders, elbow sensors on the trainee's elbows, wrist sensors on the trainee's wrists, hip sensors on the trainee's hip joints, knee sensors on the trainee's knees, and torso sensors on the trainee's torso. Each motion sensing device is equipped with adjustable straps, adhesive or magnetic attachments for detachable connection to the trainee's body. By setting these sensors at corresponding parts of the body (different barbell training programs can be equipped with the required sensors), changes in the spatial position of these parts can be effectively monitored. At the same time, barbell spatial positioning and human skeletal point recognition can be performed through video image data from vision devices, which is used for calculating and analyzing precise parameters such as barbell status, skeletal point status, number of movements, and speed during the movement. In a further preferred embodiment, the activity sensing device 12 is an IMU sensor, particularly a six-axis IMU sensor. This sensor can output high-precision parameter capture results for the direction, amplitude, and speed of movement at each node during training. Furthermore, it can evaluate body posture during exercise by analyzing key skeletal point parameters in real time, including core evaluation indicators such as foot inversion / exversion angles, elbow inversion / exversion states, scoliosis degree, shoulder height discrepancy, winged scapula angle, head tilt angle, and pelvic tilt amplitude. This data effectively records data, which helps improve the standard of training movements. Improved movement standardization naturally increases training efficiency and effectiveness, reduces injuries, and further enhances the intelligence of barbell fitness products. Since the activity sensing device 12 is portable, it is advisable to wirelessly connect to the system processing module 2 via a Bluetooth unit (such as Bluetooth 5.0 protocol) to transmit data and collect training activity parameters in real time, avoiding interference and potential hazards caused by wired connections.

[0023] The system processing module 2, according to the system function settings, allows all hardware components to control other modules, realizing data flow, synchronization, and functional linkage throughout the system. This module may include calculations such as barbell spatial positioning and human skeletal point spatial positioning based on data acquired from the vision device 11, calculation, analysis, and evaluation of IMU parameters acquired from the activity sensor device 12, and system units for data storage and system control. The vision device 11 and the activity sensor device 12 are interconnected via a data bus to achieve data fusion and compensation calculations. The database storage facilitates subsequent querying and tracing of human assessment data, improving the operability of barbell exercise fitness products and providing reliable data support. Those skilled in the art can make corresponding settings according to the system functions. A more detailed description of this module is provided here without affecting the clear understanding of the technical solution of this utility model by those skilled in the art.

[0024] The interactive module can be connected to the system processing module 2. Some of the calculated, analyzed, and evaluated results are displayed to trainees, coaches, and other personnel through the interactive module for visual viewing of the training situation. The interactive module can also be used by users to control the system operation, set training types, monitoring modes, etc. The interactive module realizes the interaction between people and the system. It can be a computer, tablet, mobile phone, or other device with a touch screen. It can connect to the system processing module through a wired or wireless connection unit to transmit data. The wired connection can be connected to the system processing module 2 through an HDMI interface.

[0025] Furthermore, the visual device 11 in the above embodiment is mainly positioned in front of the trainee to enable online monitoring with more comprehensive and detailed observations (e.g., allowing coaches to more clearly observe the trainee's overall or partial posture from various angles online, which can be used to determine whether the corresponding training items and muscle groups are performing the movements correctly or if there are any problems, thereby improving training effectiveness and reducing injuries). The visual device 11 in the above embodiment is a first visual device, and a second visual device is also provided on top of it. Alternatively, the visual device in the above embodiment can be replaced by the second visual device, which is used instead of the first. The specific choice depends on the usage environment and system function requirements. Here, a detailed description is provided for a structure with both a first and a second visual device, which can simultaneously achieve real-time monitoring and detailed observation during training. The first visual device is also positioned in front of the trainee and can achieve the same function. The second visual device is mounted using a motion device that can move around the periphery of the trainee's activity space. In this way, the second visual device can adjust the shooting direction according to the observation position to capture the corresponding parts of the trainee, thereby achieving more comprehensive and detailed observations. The second vision device can employ high-definition camera equipment to facilitate high-definition close-range observation and judgment. To avoid safety hazards arising from the installation of the second vision device during training, the motion device described here includes a motion track deployed around the perimeter of the trainee's activity space, a drive module mounted on the motion track, a lifting guide frame mounted on the drive module, and a lifting drive module itself. The lifting drive module includes a lifting base for mounting the second vision device. The second vision device is equipped with a pitch adjustment drive mechanism. The motion track can be a straight line or an arc-shaped track primarily corresponding to the two sides of the trainee, such as... Figure 2 The diagram shows straight tracks set on both sides of the trainee, or square, elliptical, circular, or U-shaped tracks arranged around the perimeter of the trainee's activity space. This structure limits the movement of the second vision device around the trainee's activity space by moving along the tracks, preventing the second vision device from moving too close to the trainee and causing safety hazards or accidents such as psychological impact or accidental collisions. The tracks can also meet the needs of movement around the trainee's perimeter. Furthermore, the second vision device can be further adjusted in position through the lifting drive module and the pitch adjustment drive mechanism to meet the needs of more movement adjustments. In addition, the tracks and the drive module can improve the stability of the second vision device, thereby further meeting the needs of lifting support, pitch support, and adjustment stability of the second vision device.

[0026] The above-mentioned modular structure of this utility model system integrates visual perception and IMU sensing data, and can use synchronization technology to achieve precise matching between the barbell's motion trajectory and the human body posture. This solution breaks through the limitations of a single sensor in strength training monitoring, and can simultaneously capture the barbell's displacement, speed and other motion parameters as well as the trainee's joint angle changes. It significantly improves the accuracy of barbell motion recognition and the standardization of the motion process for deadlifts, squats and other exercises, providing data support for sports training and rehabilitation therapy.

[0027] The above embodiments and figures are not intended to limit the product form and style of this utility model. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this utility model.
