Title:
磁場抑制システム、船舶、及び制御方法
Document Type and Number:
Japanese Patent JP6983612
Kind Code:
B2
Abstract:
To provide a magnetic field suppression system, a ship and a control method capable of detecting in real time a magnetic field generated by a hull and of effectively demagnetizing.SOLUTION: The magnetic field suppression system has a function to effectively suppress the magnetic field generated by the ship, and comprises a demagnetizing coil 4 to generate the magnetic field of an opposite polarity to the magnetic field generated by the ship, a first magnetic detecting part 2 to detect the magnetism generated by the ship, a second magnetic detecting part 3 to detect the magnetism generated by the demagnetization coil 4 and a control unit 7 to control the current flowing through the demagnetization coil on the basis of the detected result by the first magnetic detecting part 2 and the second magnetic detecting part 3.SELECTED DRAWING: Figure 1
