PRODUCT DESCRIPTION
3.7
Output of measured values
Fig. 17: View of scanning angle
In addition to landmark detection, the NAV245 can also display the measured surrounding
contour on the connected host (mixed mode).
The measured values can be transferred to a connected computer system and evaluated
there (“Communicating data via telegrams” on page 29). The host can compute the
position of the automated guided vehicle using these measured values.
Navigation by means of the measured surrounding contour is useful at locations where no
reflectors can be fixed, such as in the cargo area of a truck.
The NAV245 outputs the following measured values on its data interface:
•
Profile of the field of view in two-dimensional polar coordinates
•
Content of a rotation (270°), e.g., starting angle of the scan, increment, time stamp for
the start of the scan, number of measured values, value and direction of the measured
distance, remission value of the measured object.
Important
It is only possible to output all measured values of a 270° scan in real-time using the
Ethernet interface.

Integrating the NAV245 into the control system of an automated guided vehicle
Recommendation
Integrating a NAV245 into the control system of an automated guided vehicle requires in-
depth programming knowledge in the area of vehicle control. You also need knowledge on
exchanging data between a laser positioning sensor like the NAV245 and the vehicle
computer. SICK AG offers in-depth training on request.
3.8.1
Data interfaces
The NAV245 has a serial host interface and an Ethernet interface. You can configure the
NAV245 via these interfaces with the help of SOPAS ET. The NAV245 also communicates
with the automated guided vehicle's computer via its interfaces.
