Abstract
The invention concerns a system for determining at least one parameter of at least one member () rotating with respect to a fixed structure (), comprising, for each rotating member (), an assembly comprising a transponder (), a code () comprising a reference singularity, a sensor () able to deliver a signal comprising a reference pulse corresponding to the detection of the reference singularity, a device () for detecting the parameter or parameters issuing from the transponder () and a device for measuring the speed of rotation of the rotating member (); the said system also comprising an activation device () which is connected to each sensor (), to each detection device () and to each speed measurement device, the said activation device being able, when a reference pulse issuing from the sensor () of an assembly is recorded, to activate the detection device () of the assembly at a moment which is a function of the indexed position of the transponder () and of the measured speed, so that the transponder () of the assembly is in the transmission/reception cone of the communication means of the said detection device.
