摘　　要：系统采用模块化设计思想,以AVR128单片机为核心,设计出了带电导线检测仪。该系统由主机和从机组成多机通讯系统,其中主机系统完成墙内电线位置检测、数字滤波、串行通讯、语音、显示、照明线路算法、中断服务、照明线路功率比较、菜单设置和与从机通讯等功能;从机系统完成键盘扫描程序和与主机通讯等功能。整个系统性能稳定,人机界面友好,操作方便,可准确获取电线的位置及走向,减少了意外事故的发生,在实际应用中具有良好的效果和广阔的市场前景。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.
