| Abstract: | To meet the microprocessor-based protection experimental teaching,design the microcomputer relay protective device.The hardware core is AT89C55WD MCU and the electric circuit function is completed.In order to get high precision in the analog to digital converting,two 10 b,bipolar input,multiplexed input successive approximation analog to digital converters are used in the instrument.So the sampling frequency would make adaptive adjusting.With configuration software in PC and friendly interface for browsing and setting,it is easy to accomplish all the experiments and do a comparison among them. |
