RESEARCH ON SCOUR MONITORING METHOD OF SINGLE DEGREE OF FREEDOM WITH MAGNETIC DIPOLE
In order to solve the problem of complex measurement matrix required by the traditional magnetic dipole location method to retrieve the magnetic dipole position according to the magnetic gradient tensor,the magnetic dipole is located only by the three-component magnetic field generated by the magnetic dipole with a single degree of freedom.According to the spatial distribution pattern of the magnetic dipole,the inversion equation of the single-DOF magnetic dipole is derived,and the single-DOF magnetic dipole location is realized.On this basis,based on the derived inversion equation,a universal channel scour monitoring method is proposed by combining the magnetic dipole single-DOF positioning method with the gravity-driven channel scour monitoring method,which can reflect the channel scour situation through the single-DOF inversion formula.
