Optical positioning system knows the way
October 2018, Sensors & Transducers
The PGV (position guided view) positioning system from Pepperl+Fuchs consists of a 2D vision sensor with integrated LED lighting, a coloured tape as an optical route indicator, data matrix codes as a tape or tag for the identification of positions, and control codes for vehicle navigation at intersections, branches, or endpoints.
Safe and precise navigation at all times
The tracking of route indicators and codes is contrast-independent and resistant to extraneous light due to the specially focused optics. With powerful integrated signal processing, the PGV sensor can identify the X, Y and Z position (where Z is the distance from the AGV to the floor)
of the AGV with precision at any time. The optical positioning system detects its angle from the route-tracking tape so that the direction in which the AGV is travelling can be corrected automatically. The sensor tolerates interrupted or dirty tape over a distance of 60 mm.
Integration-friendly sensor concept
The housing of the PGV sensor is compact, shock resistant, and impact resistant with the IP67 degree of protection. It is mounted on the bottom of the AGV, without the need for time-consuming alignment. When it comes to control technology, the positioning system can be linked to RS-485 and all common fieldbuses.
The camera-based PGV system enables AGVs and other autonomous vehicle concepts to navigate freely with no extensive ground work, such as that required for inductive or magnetic route tracking technologies, necessary. Distances, intersections, branches, buffer sections, or transfer points can all be set up quickly by the simple application of route-tracking tape and visually detectable marks on the ground. PGV offers flexible integration options in relation to the common AGV vehicle controls and fieldbuses.
