Abstract: Aiming at enhancing the reliability of the automatic door operation,S7200 programmable logic controller(PLC) was used as the core of the automatic door system.The principle of control system was analyzed with description of the control system hardware. It was introduced that the working process of control circuits about human body detection sensor and automatic door position detection and obstacle detection and so on. it was introduced how to choose a PLC type, to really settle the I/O orders.Combining the operation characteristics of programmable controller, a reasonable optimization was made for the work flow of the system. On this basis, using structured programming method,the program flow charts of main program module and opening door subroutine module and closing door subroutine module were developed.The debugging of the control system was developed and the control system has been adopted.The practical application shows that the control system is good and reliable.
Key words: programmable logic controller(PLC); S7200; automatic door; control system
