Unmanned vehicle line patrol method and system based on preset sequence radio frequency tags and unmanned vehicle

The invention relates to the technical field of automatic navigation, in particular to an unmanned vehicle line patrol method and system based on preset sequence radio frequency tags and an unmanned vehicle. The automatic line patrol method comprises the following steps: arranging a plurality of radio frequency tags with unique numbers on a to-be-patrolled path; through a plurality of detection antennas arranged at the front end of the unmanned vehicle, detecting a radio frequency tag and a serial number thereof in front of the unmanned vehicle in real time; according to the detected numbers of the radio frequency tags and a preset radio frequency tag arrangement sequence, determining the next target tag to be passed on and off the path, determining the current advancing direction according to the signal intensity between the plurality of detection antennas and the target tag, and controlling the unmanned vehicle to pass through the target tag along the advancing direction so as to complete line patrol.
