METHOD FOR AUTOMATIC DEMAGNETIZATION OF SHIPS Russian patent published in 2022 - IPC B63G9/06 H01F13/00 

FIELD: ship demagnetization.

SUBSTANCE: invention relates to the field of ship demagnetization. The method for automatic demagnetization of the ship consists in determining the compensation currents in the sections of the compensation windings (CW) of the demagnetizing device (DD), measuring and storing the initial values ​​of the currents in all sections of the DD windings, which provided compensation for the three components of the initial magnetic moment of the ship, and the initial values ​​of the three components of induction. When swimming at each step of the discrete current control process, the current strength in each section is simultaneously measured and the differences between the initial and current values ​​are calculated, the current values ​​of the induction components are measured and the differences between the initial and current values ​​are calculated. Then, in parallel, in each of the onboard MSM channels, a sensor with the maximum induction difference is selected, the induction increments are subtracted from this difference, the ratio of the result obtained to the magnetic induction constant of the CW section adjacent to this sensor is determined, which is the value of the required current change in this section, and in At the beginning of the next step, a current is set in the section equal to the sum of the calculated change and the initial value of the current.

EFFECT: ensuring the minimum values ​​of the components of the magnetic moment of the ship.
