摘要
介绍了双控二用一备恒压供水闭环变频控制系统。只对处于工作状态的控制对象配置控制器,用两个控制器实现对三个控制对象M1、M2、M3任意组合成二用一备状态的切换控制。最大限度地减少控制器的数量和容量,降低控制器硬件投资成本。
This article presents the duplexing dual-purpose and one-spare frequency conversion control system with constant pressure and closed loop to supply water.This system only configures controller for the controlled objects at operating state,and three controlled objects M1、M2、M3 are implemented switching control on any combination as dual-purpose and one-spare state by 2 controllers.The number and capacity of the controller are minimized to reduce the controller hardware investment costs.
