Application of PLC in Pneumatic Measurement Control System

[摘要] Aiming at the complicated structure and poor applicability of traditional pneumatic measurement control system, a method of pneumatic measurement PLC and inverter control is given. Firstly, based on the brief introduction of pneumatic measurement control, the PLC and inverter control system is established, then the control of pneumatic measurement is realized through PLC control, and finally the pulse encoder counting and collecting data are dynamically detected by means of frequency conversion speed control. Automatic control system is established by PLC technology, which is feasible and effective in practical application. Experimental results show that the mathematical expression of the system is consistent with the results of image simulation. The controller is running well and meets the requirements of pneumatic measurement control.
