Design of Automatic Door Control Device
Abstract:With the rapid development of science and technology, people's living standards improve, people's lives have also occurred in the major changes, automatic door also gradually in the everyday life of the common field income to popularize, become some public places, such as hospitals, supermarkets, banks. Hotels, such as an indispensable part of. Automatic door has the advantages of convenient and simple, elegant, quiet, worry and effort and other characteristics, it is convenient to manage, strong practicability and strong stability. In order to further improve the reliability of automatic doors, this paper proposes an automatic door control system with FX2N-32M type PLC as the main controller, and made a reasonable optimization of process control system. Also gives the software design of the control system program flow chart and program design of ladder diagram, the external terminal connection diagram.
