Device and process for acquisition of measurments using a digital communication bus, particularly used during aircraft tests
First Claim
1. Device for acquisition of measurements using a digital communication bus (10) and a computer system characterized in that it comprises:
- a bus arbitrator (11) connected to this bus (10), with the function of acting as the bus master and which synchronizes measurements made using sensors (14), several items of slave equipment (13) connected on this bus (10), to which these sensors (14) are connected, two line termination devices;
the first being integrated in the bus arbitrator (11) and the second being integrated into slave equipment (13) at the other end of the bus (10) opposite the bus arbitrator (13).
