Method for measuring induced magnetic field Ziy by unilateral transverse geomagnetic simulation coil

Abstract

The invention relates to a method for measuring an induced magnetic field Ziy by a unilateral transverse geomagnetic simulation coil. The unilateral transverse geomagnetic simulation coil is laid on asingle wharf at an XC station, a magnetic sensor array is paved at the underwater standard measuring depth of the XC station, a computer controls a high-precision geomagnetic analog power supply to energize or unenergize the unilateral transverse geomagnetic simulation coil and acquires magnetic field values of the magnetic sensor array under various situations, and when the earth magnetic fieldacts in the transverse direction of a ship, the transverse induced magnetic field Ziy produced by the induction of the ship at the standard measurement depth is obtained by calculation. As the unilateral transverse geomagnetic simulation coil is laid on the single wharf, the measurement of the transverse induced magnetic field by a simulated geomagnetic field is realized, the limitation of the application of a simulated geomagnetic field measurement Ziy project to double wharves is broken through, a new idea is provided for the future construction of the XC station, and particularly for the upgrading and the reconstruction of the XC station with the existing single wharf or without the wharf, the cost-efficiency ratio of engineering construction is greatly improved.

Description

technical field [0001] The invention relates to a magnetic signal testing technology, in particular to a method for measuring a transverse induced magnetic field Ziy by a single-side transverse geomagnetic simulation coil. Background technique [0002] Under the action of the earth's magnetic field, the steel ship will generate an induction magnetic field, and the transverse induction magnetic field Ziy (the magnetic field induced by the ship when the earth's magnetic field acts along the transverse direction of the ship) is a must for the ship to obtain when it performs magnetic treatment at the XC station. The magnetic field component of the transverse induced magnetic field Ziy currently has the following two measurement methods: [0003] 1) Direction measurement method - it belongs to the traditional method, which is obtained by E-W direction measurement without laying analog coils; [0004] 2) Geomagnetic simulation method - the technology commonly used at present, by ...
