AI Technical Summary
The existing cell door transmission mechanism cannot achieve emergency stop when encountering obstacles during movement, which easily leads to jamming or failure to open normally. In addition, the fixed-point control is poor, which can easily cause the sliding door to collide with the door frame.
The motor is controlled by both an encoder and a magnetic induction limit switch, achieving dual limit control during movement. An absolute encoder is used to detect the translation distance, and an infrared induction switch monitors the rack end to ensure precise motor control.
It enables sliding doors to stop suddenly when encountering obstacles, avoiding problems with jamming and normal opening, while improving control flexibility and positioning accuracy, and preventing sliding doors from colliding with the door frame.
