摘　　要：地下管线被视为城市的生命线。分析了地下管线定位仪的基本原理,并在此基础上详细介绍了基于ATmega 128单片机的数字化地下管线定位仪的硬件实现和软件实现,重点分析了基于磁保持继电器的分时供电电源电路。ATmega 128单片机实现了地下管线定位仪的数字化,使得定位仪能快速、准确地对地下管线进行水平定位和垂直定深。The underground pipeline is considered the lifeline of the city. This paper analyzed the basic principles of the underground pipeline locator, and introduced in detail the hardware implementation and software implementation of the locator based on the singlechip of ATmega128. And the time--sharing power supply circuit based on magnetic self--perpetuating relay was particularly explained. ATmega128 realizes the digital of the underground pipeline locator, and the locator can quickly and accurately determine the plane position and vertical depth of the underground pipeline.
