Problems solved by technology

[0004] However, the way of using magnetic tape navigation is susceptible to environmental factors such as metal substances on the driving path that affect the sensing of the magnetic sensor, and the distance between the magnetic tape and the magnetic sensor will also affect the magnetic sensor
In other words, when the driving path of the automatic guided vehicle has a slope or there are metal goods placed around it, the accuracy of the automatic navigation system may be seriously affected
In addition, since the edge of the magnetic tape can detect the N pole and the S pole at the same time, it may also cause the corresponding magnetic sensor to cause misjudgment and make the automatic navigation system inaccurate

Abstract

The invention provides a transport vehicle and a control method thereof. The transport vehicle includes a power unit, a sensing unit and a drive control unit. The power unit is configured to respond to a drive signal group so that the transport vehicle can travel on a guide magnetic track. The sensing unit is configured to sense a magnetic force on the guide magnetic track, and generate a plurality of sensing signal groups in a sensing period. The drive control unit is coupled between the power unit and the sensing unit. The drive control unit is configured to receive the sensing signal groups; conduct averaging process of the sensing signal groups to obtain relative position information of the transport vehicle to the guide magnetic track; and provide the drive signal group to the power unit based on the relative position information, so that the central position of the transport vehicle is substantially aligned to the central position of the guide magnetic track.

Description

technical field [0001] The present invention relates to an automatic navigation system and its automatic navigation method, and in particular to a magnetic induction transportation vehicle and its control method. Background technique [0002] Automatic Guidance Vehicle (AGV) is a transport vehicle that uses an automatic navigation system to drive along a preset path. The automatic navigation system of the automatic guidance vehicle can be divided into direct coordinate navigation (Cartesian Guidance), Wire Guidance, Magnetic Tape Guidance, Optical Guidance, Laser Guidance, Inertial Guidance and Visual Guidance. [0003] In the automatic navigation system using magnetic tape for navigation, it usually uses a tape attached or buried on the path, and a magnetic sensor that can sense the magnetic force of the magnetic tape is installed on the transport vehicle to achieve the purpose of navigation. Because the magnetic tape is easy to lay, the automatic guided vehicle using the ...
