The invention discloses a view finding control method of head-mounted equipment, and relates to the technical field of intelligent wearable equipment. The method comprises the steps of determining a fixation point of a wearing user in a three-dimensional space based on a sight line direction and a fixation depth; projecting the fixation point to a pixel plane of a main camera of the head-mounted device to obtain a corresponding pixel coordinate; and based on the pixel coordinates and a preset shooting composition rule, adjusting a target corresponding to the fixation point to a shooting picture framed by the electronic cutting window according with the preset shooting composition rule by adjusting the position of the electronic cutting window in the shooting picture of the head-mounted device or adjusting the orientation of a main camera of the head-mounted device. By fusing the eye physiological signals, the head space posture and the camera space geometry, the three-dimensional coordinates of the fixation point of the wearing user are accurately calculated, the head-mounted equipment is intelligently controlled to accurately shoot the image with the target corresponding to the fixation point of the wearing user as the center, and the function of automatically shooting high-quality pictures is achieved.

This invention relates to the field of tire manufacturing equipment technology, specifically to a control system and method for the coordinated control of the feeding roller and forming drum in tire rubber strip winding. The system includes core control, signal acquisition, drive execution, and auxiliary support modules, forming a closed-loop architecture through electrical connections. The core control module uses a 1ms operation cycle PLC and an industrial SD card. The signal acquisition module integrates a tension sensor, a laser displacement sensor, and an incremental encoder. The drive execution module includes a dual servo system, a floating roller, and a tension roller mechanism. The control method achieves master-slave axis synchronization through real-time calculation using electronic gears, performs roll diameter compensation based on volume conservation, employs a feedforward + feedback dual-layer control, and combines a tanh-type S-surface controller to correct tension and floating roller position errors. It adapts to independent parameter settings and inter-layer error clearing for multi-layer winding. This invention improves the rubber strip bonding accuracy and thickness consistency, enhancing system adaptability and production reliability.
