Application of new radio induction technology to position detection

In automatic positioning of industrial rail locomotives,it is necessary for accurate measurement of mo-bile locomotive location,with which automatic positioning control system makes locomotive move towards its destina-tion and stop automatically.Aa method for position detection by the new radio induction is proposed.Based on the principles of electromagnetic induction,the information transmission system between sending coil and coded cable is built.The mobile locomotive location can be acquired by detecting the phase and amplitude of induced emf.The prin-ciples and methods of the new radio induction technology to position detection are studied.Some detection formulas are deduced,the circuit model of position detection is also designed,and some experiments for position detection by the radio induction are carried out.The research results show that the new radio induction technology has a better anti-interference performance can be applied in position detection,and the detection accuracy is 2mm.
