| Abstract: | Design and impelmentation of intelligent detection and control circuit of pressure in industrial online chromatogram equipment are introduced.The system achieves automatization of the process with increment PID,and can control MOSPET by PWM.The output padlock of PWM is carried out by the circuit that is protected when pressure goes over the top.The system forms the closed loop system.The system uses CAN bus to communicate with upper-computer and Cygnal 8051 SOC mixed-signal MCUs as the control center of the system. |
