A transferrable shell-based magnetic flux density distribution model for a magnetic proximity detection system

A magnetic proximity detection system relies on magnetic flux density measurement to determine the position of a worker relative to a mobile mining machine. It is desirable for the magnetic flux density distribution to be automatically adjustable to conform to the protection requirements for the different types of machines and working environments. In support of the development of an automatic field distribution adjustment process, we developed a transferrable magnetic flux density distribution model. The transferrable model can also be used to control and stabilize the field against field drift to enhance system performance.
