The present application adopts the brushless motor, combines the standby protection countdown with the zoned, angularly linked collection of the force parameters and the dynamic impedance regulation and control, so as to realize the portable and silent operation of the equipment and the personalized resistance adaptation, and to enhance the operation stability and the training adaptation accuracy.

The invention provides intelligent resistance training equipment and method. The method comprises the following steps: synchronously collecting resistance signals of a neck and lower limbs when a user executes a collaborative resistance action; determining force application delay time between the neck and the lower limbs according to the resistance signals of the neck and the lower limbs; according to the angular velocity component of the neck of the user and the anti-resistance signal of the neck, determining a posture-force coupling coefficient when the user executes the collaborative anti-resistance action; determining a load adjustment coefficient of a lower limb target load based on the force application delay time and the posture-force coupling coefficient in combination with a preset load adjustment rule; and adjusting the lower limb load applied by the equipment according to the load adjustment coefficient, and generating prompt information containing posture coordination abnormity at the same time. By adopting the scheme of the invention, the training load conforming to the current coordination capability of the user can be dynamically allocated.

This invention relates to the field of intelligent sports training equipment technology. It discloses an intelligent sports training machine with motion posture recognition, comprising: an equipment frame; a drive assembly mounted on the equipment frame, the drive assembly including: a motor; a reel connected to the output shaft of the motor; and a rope wound around the reel, the free end of which extends to the outside of the equipment frame. This invention offers significant advantages over traditional training machines. It achieves stepless resistance adjustment through motor drive, and with closed-loop control, ensures precise and stable resistance that can be dynamically adjusted according to posture. It achieves three-dimensional recognition of key points of the human skeleton through visual acquisition and posture analysis, and combined with audio-visual feedback, allows users to correct their movements in real time, improving training effectiveness. It automatically reduces resistance in abnormal postures and provides emergency braking in dangerous situations, significantly reducing the risk of injury. It can also record training data for digital management, providing support for personalized training.

The application relates to a mixed reality office scene bad sitting posture correction method and device, equipment and medium, which are suitable for a mixed reality head-mounted device. The method continuously acquires current spatial posture information of a user's head and shoulders, calculates head position offset, left shoulder position offset, right shoulder position offset and head angle offset based on the current spatial posture information and a reference posture model, and judges whether the user is in an abnormal posture state according to each offset and a corresponding threshold value. When the abnormal posture state lasts for more than a preset time length, the mixed reality head-mounted device is controlled to visually modulate display content to prompt the user to adjust the posture. The application can improve the accuracy of bad sitting posture recognition and reduce the interference on the user's office process.

This invention provides an interactive sports training assessment method and system, belonging to the field of sports training assessment technology. The method involves: distributing an assessment item set in a virtual training assessment scenario; sorting the items according to the trainee's exercise habits and psychological state for each assessment item; sequentially displaying the items and capturing training behavior posture sets; globally comparing these with a standard posture set to construct joint point abnormal posture vectors; and combining joint point behavior trajectories with standard trajectories to construct point abnormal vectors; combining and analyzing these results to obtain single-item assessment results; and finally, processing all results and sending them to the assessment terminal. This invention achieves standardized quantification of assessments, improves the objectivity and accuracy of assessments, and provides a scientific reference for sports training.
