【Abstract】 Adopting the modular design concept and based on AVR128 microcontroller,this paper gives a design of a live wire detector. The multicomputer communication system is composed of the master machine and a slave machine. The master machine performs such functions as detection of wire positions in the wall,digital filtering,serial communication,voice,display,lighting line algorithm,interrupt servicing,lighting circuit power comparison,menu setup and communication with the slave machine,and the slave machine performs such functions as keyboard scanning sequence and communication with the master machine. The whole system has stable performance,friendly man-machine interface and convenient operation,and can accurately acquire information about wire location and direction,thus reducing the possibility of accidents. In practical application,the system has good effect and vast market prospect.更多还原
