| Abstract: | The design of a intelligent monitoring system based on high performance MCU of ATmega48 is introduced. It achieved the function of real time monitoring the current multiple current powers. It can also cut down the connect between power and equipment to protect the equipment when there is a failure in equipment. The hardware of the system consist of logic self locking circuit, multiplex AD data acquisition, communication between computer with MCU and communication between double MCUs etc. It discussed the overburden automatic protecting circuit in detail of real time measure principle. It also realized the display & control of human computer interaction by Lab Windows/CVI. The interface is easy to be manipulated. |
