Electromagnetic rail track detection method for intelligent motor-driven carrier

In order to keep the AGV tracing signal detection system in high reliability and accuracy,a signal detection method with three-sensor detection program is proposed.Compared with other method with multi-sensor or switch circuit,the proposed one can not only reduce the number of sensors,but also expand the linear region of operating characteristics of a track detection system,because the exact direction of the angle can be calculated out when the differential signal processing and threshold comparison is considered.Test results show that,the track testing system is stable and effective.
