| Abstract: | The paper introduced structure and working principle of an electric executer of hydro-valve based on STC89C51 single-chip microcomputer and expounded composition and design schemes of software and hardware of control system of the electric executer.The control system takes STC89C51 single-chip microcomputer as core,uses ring distributor and power amplifier to control rotator speed and rotator angle of step motor so as to control opening degree of the hydro-valve,and adopts a flow sensor and a pressure sensor to collect hydro-parameter signals,which are sent to STC89C51 single chip microcomputer after AD conversion so as to form closed loop control.The control system has functions of CAN communication and human-machine interaction. |
