Abstract

In the complicated factory production environment, carry out the complex large-scale production, for the electromagnetic environmental impact, The acquisition of the analog signals of PLC will appear distortion or drift, after difference differential equation of the low-pass filter, do digital filter by PLC.Achieve the the purpose of removing interference of analog quantity, and apply to the actual constant liquid position control.
