It is believed that with the improvement of the guiding technology of the AGV car, there will definitely be a better technology and strategy in the future. To achieve the perfect guidance of the AGV car.Īlthough each guiding technology of the AGV car can meet the needs of the enterprise, it has certain limitations. Because each guiding method has its limitations, in order to meet the needs, the above guiding methods can be combined, and the two guiding methods can achieve seamless docking. The main technical difficulty lies in image processing.Ĭomposite guidance refers to the combination of multiple guiding technologies. The AGV collects image information through the visual sensor during driving, and determines the current position of the AGV by processing the image information. The principle of this technology is to install a CCD camera on the AGV. Vision guidance is the most promising AGV guidance technology. The laser positioning device mounted on the AGV emits a laser beam and collects signals reflected from reflectors at different angles to determine its current position and orientation based on triangular geometry operations. A positionally accurate laser reflector is mounted around the AGV travel path.
Laser guidance is mainly achieved by reflection of light. The main principle is to paint or paste the ribbon on the travel path of the AGV, and to guide the identification of the ribbon image signal acquired by the optical sensor. This technology is also relatively mature. The identification and tracking of strong and weak, to achieve the guidance of AGV. The induction coil on the AGV passes the navigation magnetic field. The metal wire is buried in the traveling path of the AGV, and the low frequency and low voltage current are applied to generate a magnetic field around the wire. This technology is the most widely used technology, and it is also a relatively mature technology.
A brief introduction to these guidance categories is now available: Currently, AGV guiding technologies appear on the market include: electromagnetic induction guidance, magnetic tape, magnetic point guidance, optical guidance, laser guidance, visual guidance, composite guidance, and the like. The core of the AGV trolley is its guiding technology.
