US 7,072,803 B2 · Device and process for acquisition of measurements using a digital communication bus, particularly used during aircraft tests

Abstract

The invention relates to a device for acquisition of measurements using a digital communication bus (10) and a computer system. The device includes a bus arbitrator, several items of slave equipment, and two line termination devices. The bus arbitrator (11) is connected to the bus (10), with the function of acting as the bus master. The bus arbitrator synchronizes measurements made using sensors (14). The several items of slave equipment (13) are connected on the bus (10), to which these sensors (14) are connected. The first of the two line termination devices is integrated in the bus arbitrator (11) and the second is integrated into slave equipment (13) at the other end of the bus (10) opposite the bus arbitrator (11).
