| Abstract: |
| A universal experimental device for microcomputer protections is developed based on AT89C55WD monolithic microcomputer.Its software and hardware design scheme,key technologies and implementation are presented.Besides AT 89C55WD,it includes the peripheral circuits of A/D converting,binary input/output,frequency measuring and communication.It combines with superordinate PC and measuring instruments to form a protection experimental system.The modularized software is designed with structural programming language KeilC51.The whole system can effectively simulate,collect and deal with usual current and voltage faults of protections and send action commands. |
