UNIPOLAR MAGNETIC GUIDANCE UNIT AND METHOD FOR GUIDING AGV

摘要

The present invention relates to a bipolar magnetic induction device capable of controlling an automatic guided vehicle (AGV) at intersections and in a work area without an additional mark sensor and measuring a wide area by using the S-pole and the N-pole of magnetic tape attached on the floor to guide the AGV. The present invention includes multiple bipolar magnetic sensors which are installed in an AGV and measures the magnetism of the S-pole and the N-pole of magnetic tape which is attached on the movement path of the AGV and generates S-pole force and N-pole force; an S-pole signal processor and an N-pole signal processor which correspond to each bipolar magnetic sensor and outputs an S-pole magnetic signal and an N-pole magnetic signal measured by each bipolar magnetic sensor as a digital signal; and a driving control unit which controls the driving of the AGV based on the S-pole digital signal and the N-pole digital signal outputted from the S-pole signal processor and the N-pole signal processor.
