Control System of Electromagnetic High-frequency Screen Based on PIC18F452

The paper proposed a design scheme of the control system of electromagnetic high-frequency screen which took PIC18F452 single-chip microcomputer as core.It gave requires and control principle of the control system of electromagnetic highfrequency screen based on PIC18F452,and introduced design of hardware and software of the system in details.The system uses the advantages of PIC18F452 single-chip microcomputer in software calculation and realizes control function of the system with the least hardware circuit.The actual application showed that the system is reliable in running and simple in operation.
