ABSTRACT:
A system for determining at least one parameter of at least one member rotating with respect to a fixed structure, the system including, for each rotating member, an assembly having a transponder, a coder, a position sensor, and a device for detecting the parameter or parameters issuing from the transponder. The system also includes a synchronisation unit connected to each sensor and to each detection device. The synchronisation unit including a device for determining an activation position of the detection device of an assembly when the transponder of the assembly is in the transmission/reception cone of the communication mechanism of the detection device, and an activation device that is able, by comparing the position of the coder with the activation position, to activate the detection device of the assembly in order to measure the parameter or parameters.
