Abstract
A method for parking detection and identification of moveable apparatus, comprising following steps of: generating a magnetic field signal containing an unique identifier for identifying the moveable apparatus by a magnetic field generator disposed in the moveable apparatus; measuring magnetic field respectively by two magnetic field sensors of a magnetic field sensing apparatus disposed in a moveable-apparatus parking place or its peripheral area, wherein a first and a second magnetic field measurements are measured; and calculating a magnetic field measurement difference for obtaining the unique identifier, wherein the magnetic field measurement difference is a magnitude of a difference of the first and the second magnetic field measurements, or a magnitude of a difference of a first magnetic field component of the first magnetic field measurement along a characteristic direction and a second magnetic field component of the second magnetic field measurement along the characteristic direction.
