Numerically Filtering Based on PLC and the Application in the Control System of the Intelligent Building
This article introduces the way Arithmetic Mean Filtering, Weighted Mean Filtering and Inertia Filtering are applied in dealing with analog signals in PLC control system. Apart from presenting the design of the corresponding numerical filtering procedure, it provides a concrete illustration by citing a case where numerical filtering is applied in Intelligent Building Control System. Facts show Application of numerical filtering effectively strengthens the liability of the system.
