【Abstract】 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.更多还原
