摘　　要：具体阐述了 MCS— 5 1单片机与线性集成霍尔元件测量传感器构成的铁金属检测装置的工作原理 。The design feature and the basic principle of ferrous metal survey are analysed in detail, which uses a line integrated Hall chip as the survey sensor. And a method of the auto correction of the zero voltage is put forward. The auto correction is done by a MCS—51 single chip microcomputer which is the core of this intelligent instrument and the block diagrams of the system are given out.
