1. Electromagnetic induction guidance

This technology application is the most common technology application, and it is also a relatively mature technology application. The metal wire is laid on the driving path of the AGV, and the low frequency and low voltage current are loaded to form a magnetic field around the wire, and the electromagnetic on the AGV. The coil establishes the guidance of the AGV based on the identification and tracking of the navigation magnetic field.

2. Optical technology application guide

The application of this technology is relatively mature. The key principle is to paint or paste the ribbon on the driving path of the AGV, and establish a guide according to the identification of the data of the ribbon image data collected by the optical sensor.

3. Laser guidance

Laser guidance is primarily built using light reflections. A precise laser reflector is installed around the AGV driving path. The laser positioning device mounted on the AGV emits a laser beam and collects the data signals reflected by the reflectors at different angles. The triangular geometry and operation are used to determine the current stage. Location and direction to establish guidance for the AGV.

4. Visual guidance

Visual guidance is the most promising application of AGV guidance technology. The principle of this technology is to install a CCD camera on the AGV. The AGV collects image messages according to the visual sensor during the driving process, and clarifies the current AGV according to the processing of the image message. position. Key technical application challenges are in image processing.

5. Composite guide

Composite guidance refers to the combination of multiple guidance technology applications, because each guidance method has its limitations, in order to meet the requirements, the above guidance methods can be used in combination, and the two guidance methods can establish interconnections. The perfect guide to building an AGV car.
