Research of Position Detected Sensor of Mine-used Locomotive Based on Geomagnetic Induction

In view of the problem of unaccurate position detection of rubber-tyred car by use of RFID,the paper proposed a design scheme of position detected sensor of mine-used locomotive based on geomagnetic induction.It analyzed detection principle of geomagnetic induction,and detailedly introduced design of hardware and software of the position detected sensor of mine-used locomotive.The actual application showed that the sensor is suitable for position detection not only of trackless rubber-tyred car,but also of track locomotive.
