| Abstract: |
| The HW and SW design of measuring and control unit based on single-chip microprocessor 80C196KC for intelligent breaker is focused. The unit monitors the signals of currents and voltages in real time and has performance characteristics of three-sect current protection, grounding leakage protection and other protections. Both HW and SW design are modularized and the system structure HW is composed of switch power supply, signal measuring unit, microprocessor system and execution component. The program is divided into main program and interruption program, and the SW design adopts the concept of cyclic scanning the interruption flag in main program. The flowcharts of main program and some interrupt programs are given. The unit has now put into practice, and the operating results reach the anticipated purpose. |
