摘要
全面的论述了两翼自动旋转门控制系统的设计。自动旋转门主要由可编程控制器(PLC)负责完成控制任务,变频器(VVF)完成对三相异步电动机的驱动。由于是由电机提供动力系统,所以安全问题被放到重要位置。采用红外传感器扫描危险位置和正常位置是否有人经过,以执行正确的命令和安全措施。
This article talks about the deign of controlling system of two wings automatic door, The controlling job of automatic door is done by the PLC. VVF drives the motor. The power is supplied by motor, so safety problem is laid on a very important place. Infrared ray sensor scans danger place and normal place whether there is person passing so the PLC can give correct command and safety measure.
