摘　　要：用S7 2 2 6型PLC对垂直升降式立体车库的电力传动系统进行控制,包括3 0KW的曳引电机一台,实现旋转、推进、开门功能的小功率三相异步电机各一台。PLC编程中充分利用步进功能,且将程序分解成多个子程序。控制指令通过RS2 3 2 / 485从上位工控机获取。Employing PLC S7-226, the controlling system is designed for vertically distributed stereoscopic garage. Its electrical driving system, consists of a frequency modulated towing motor of 30KW, and asynchronous mini-motors which can realize operations such as rotation, push and pull, open and close the door, respectively. Make full use of the PLC's sequential function chart, the controlling program is divided into several subroutines. Command words of controlling are transmitted from the industrial computer to PLC.
