DESIGNING AUTOMATIC CLOSING AND OPENING SYSTEM FOR SCHOOLS
Abstract
This paper presents the idea of designing an automatic opening and closing system for classrooms, offices, seminar rooms, etc. at schools. In particular, the mechanical design consists of a screw transmission - nut combined with a slider - slider mechanism to convert the translational motion into a rotating motion, ensuring that the door (single or double wing) opens or closes smoothly; electrical – electronic components including electrical circuits, cruise switch, push buttons... ensure safe and convenient remote closing and opening. Automatic door opening and closing system reduces the labor force because we only need to sit in the operating room and press the button to safely close and open classrooms. In addition, in the classroom, you can also use remote control or switch to close and open the doors.
