Based on the principles of electromagnetic induction, the mobile locomotive location can be acquired by detecting the phase and amplitude of induced emf. The basic principle of the induction radio detection and the characteristics of electromagnetic induction are emphasized. The frames of coded cable are analyzed. The principles of position detection are described. The formulas of position detection are derived and the circuit
