at a completely automated motor vehicle test bed
On a completely automated test bed motor vehicle seats should be checked for their encumbrance. The following features should be tested and recorded:
In order to be able to make a well defined statement about the categorization of the motor vehicle seat, the measurement data must be recorded and networked and deposited together as test result on the PROFIBUS level.
All test data should be transferred at the same time for storage, in order to obtain relevant samples of information for comparative logging of this test. A tare function is a consideration for mounted sensors addressing the issue concerning initial load (dummy load).
For the recording of all mechanical values following sensors are used:
All sensor signals are recorded by 4 individual Sensor Profibus Modules 9221. Concomitantly the modules display the sensors with voltage and evaluate their signals. The transferring of measurement data takes place in parallel via PROFIBUS. The tare activation concerning a possible initial load, which can be modelled as a dummy, takes place directly via simple PLC unit communication, over PROFIBUS.
