In automatic positioning of industrial rail locomotives, it is necessary for accurate measurement of mobile locomotive location. At present, there are many problems such as low precision of precise position measurement and serious interference.In this paper, the design requirements and methods of automatic running control of locomotive were presented, and the principle of induction wireless position detection and the method of high-precision position detection were expounded. Based on the principles of electromagnetic induction, the mobile locomotive location can be acquired by detecting the phase and amplitude of induced emf. The characteristics of induction wireless data transmission and the suppression method of the same frequency interference were detailly presented. Finally, the development prospects of railway locomotive positioning control were discussed. The locomotive positioning technology based on induction wireless introduced in this paper has a better anti-interference performance, and the detection accuracy is 2 mm, and has some reference value for the positioning control and automatic running of the rail working locomotive.
