Design on dynamic measuring and controlling system of driver

Two single chip microcomputers C8051F020 are used to design software and hardware of dynamic measuring and controlling system of electromagnetic valve driver. In the design of hardware circuit, RC filter circuit and photoelectricity coupler TLP550(TOSHBAO) are designed to achieve the goals including filtering high frequency disturbances, collecting high frequency signals, preventing external disturbances from entering the system and enhancing the reliability of the system. In addition, many superfluous designs are created when hardware circuit and bottom software structure are designed in order to facilitate the system secondary development.
