摘要： PROBLEM TO BE SOLVED: To provide a method for estimating permanent magnetism of a hull, which is capable of estimating permanent magnetism of the hull when a magnetic field is applied to the hull before degaussing is performed. SOLUTION: A specimen made of steel which is the same as the steel of the hull to be degaussed is created (ST1), and magnetization characteristics are measured by changing the magnetic field applied to the specimen (ST2). From the measured magnetization characteristics of a plurality of patterns, a Preisach's distribution chart for the steel is created (ST3). A hull numerical calculation model corresponding to a well-known numerical calculation method is created (ST4), and an applied magnetic field for each element is calculated (ST5). A Preisach's diagram corresponding to the applied magnetic field calculated is created for each element (ST6); permanent magnetism of each element is calculated based on the Preisach's distribution chart and the Preisach's diagram (ST7); permanent magnetism around the hull is estimated by the numerical calculation method based on the estimated value of permanent magnetism of each element (ST8); and an estimated value of permanent magnetism around the hull after magnetic processing is output (ST9).

摘要： PROBLEM TO BE SOLVED: To provide a method for magnetically measuring warships capable of separately measuring the permanent magnetism PLM and the vertical magnetism VM in the bow and stern directions of a warship.
SOLUTION: Triaxial magnetic sensors 2 and 3 are arranged on the left and right sides of the warship 1 to be measured, and a triaxial magnetic sensor 4 is arranged at a sea bottom below the keel. Magnetic fields are measured with the triaxial magnetic sensors 2 and 3 when the bow of the warship to be measured is turned northward and southward. By computing their Hx components, the permanent magnetism PLM and the induced magnetism ALM in the bow and stern directions are separated from each other. A model of computed permanent magnetism PLM is created and converted into a magnetic field waveform of the triaxial magnetic sensor 4 to separate the magnetism PLM and the vertical magnetism VM in the bow and stern directions from each other.

摘要： PROBLEM TO BE SOLVED: To provide a demagnetizing system for detecting the change in the local permanent magnetism of a hollow structure and maintaining a magnetic field appearing in the outside minimum at all these. SOLUTION: A detection signal of a magnetic detector 5 for individual coil control is divided into an induction component and a permanent component, for the noise and other correction part 14. The change amount of the permanent component is calculated and compared with a target value 9 through a subtracter 10. Power supply to each demagnetizing coil 7 is so controlled that the permanent component becomes equal to the target value 9. A detection signal of a magnetic detector 6 for block coil control is divided into an induction component and a permanent component for the noise and other correction part 22. The change amount of the permanent component is calculated and compared with a target value through a subtracter 16. Then a current command correction signal for block coil control is obtained and added to a signal from a block control system 19 by an adder 21, thereby controlling the current to be conducted to a block coil 8.

摘要： PROBLEM TO BE SOLVED: To provide a ship outer magnetic field monitoring device suitable for safety sailing of a ship. SOLUTION: Correlation coefficient calculation 6 of inner and outer magnetic fields is performed by a detected value of an outer magnetic field detector, and a detected value of an inner magnetic detector 2 taken in the initial measurement. Calculation 8 of coil generated magnetic fields generated inside and outside the hull is performed by the degaussing coil current and the coil data. The inner magnetic field in the degaussing state is calculated by adding the calculated inner magnetic field and the detected value of the inner magnetic detector 2, the geomagnetic field is subtracted from the calculated value, and the outer magnetic field by the permanent magnetic field is calculated by using the previously found correlation coefficient Kb. The outer magnetic field by the induction field is calculated by using the previously found relative coefficient Ka. Calculation 11 of the outer magnetic field in the non-degaussing state by the permanent magnetic field and the inductive magnetic field is performed, the outer magnetic field found by the demagnetized coil generated magnetic field calculation 9 is added, and therefore, the outer magnetic field of a ship can be estimated, and the result is displayed on a display 4.

摘要： PURPOSE:To lessen the number of sensors and economize a measuring system by laying three magnetism detectors at a fixed interval ion a straight line in a predetermined direction of the bottom of the sea in a measured sea region. CONSTITUTION:Three magnetism detectors D1-D3 are laid at a fixed interval on a straight line in a predetermined direction of the bottom of the sea in a measured sea region. A ship is made to sail from far away in the direction nearly perpendicular to the straight line to obtain distance between and magnetic moment of the ship and a central magnetism detector D2 by trial and error from an approximate position of the ship in the beginning of the measurement, approximate point magnetism dipole moment and detecting signals of magnetism detectors D1, D3 at both ends. Magnetic moment given to the proximity of the ship is obtained from the obtained magnetic moment, the sailing ship, the detecting signals of the magnetism detectors D1-D3 and the calculated distance to figure out the magnetic signal of a predetermined distance.
