Abstract

The invention discloses a portable space magnetism distribution measurement system which comprises a magnetic sensor, a data collecting module, a battery, a machine frame and a distance measurement module, wherein the signal end of the magnetic sensor is connected with the data collecting end of the data collecting module, and the magnetic sensor, the data collecting module, the battery and the distance measurement module are all installed on the machine frame. The distance measurement module comprises a pull wire and a pull wire induction device, wherein the signal output end of the pull wire induction device is connected with the collected trigger signal input end of the data collecting module. When space distribution of a magnetic field in a specific area is measured, firstly, the head end of the pull wire is fixed to a start point, an operator carries the measurement system to walk along a to-be-detected path, the data collecting module is triggered through a distance signal induced by the distance measurement module, and the equally-spaced magnetic field distribution of the to-be-detected space in the walking direction can be obtained. The portable space magnetism distribution measurement system has the advantages of being accurate in distance positioning, convenient to operate and low in time cost and especially suitable for magnetism distribution measurement operations of a small outdoor area.

Description

technical field [0001] The invention relates to a space magnetic distribution measurement device used for magnetic exploration and magnetic measurement in the field, in particular to a portable space magnetic distribution measurement system with accurate measurement positioning and easy operation. Background technique [0002] At present, when measuring the spatial magnetic distribution of a specific area in the field, the method of delineating the grid is generally used, first determine the measuring points of the measuring area, and then measure point by point. The tools used for the measurement are usually magnetometers or magnetic gradiometers. , The measuring instrument itself does not have the function of measuring point positioning. For a space area with a large area and a wide distance between measuring points, the position of the measuring points can be determined one by one by GPS positioning or real-time differential GPS (RTK) positioning, and then the magnetic fi...
