Abstract

Des capteurs 30 sont montés sur une pièce tournante, et les grandeurs physiques qu'ils perçoivent sont destinées à être transmises à une seconde pièce fixe. La partie tournante comprend un ensemble embarqué 20, de modulation par impulsions codées. La partie fixe comprend un générateur d'alimentation, qui à travers un transformateur tournant d'alimentation 11, 21 alimente en énergie l'ensemble embarqué 20. Celui-ci donne en retour les grandeurs physiques perçues par les capteurs sous forme de signaux modulés par impulsions codées, qui modulent ensuite par décalages de fréquence un signal porteur transmis à travers un transformateur tournant de signal 22, 12. Une tête de réception 13 réalise la démodulation. Ensuite, on recouvre les bits 14 puis la synchronisation de cycle 15, après quoi la décommutation permet la restitution des grandeurs physiques sous forme de signaux analogiques, ainsi que leur mesure et leur enregistrement 17. Application notamment aux mesures effectuées sur machine tournante.Sensors 30 are mounted on a rotating part, and the physical quantities that they perceive are intended to be transmitted to a second fixed part. The rotating part comprises an on-board assembly 20 for pulse code modulation. The fixed part comprises a power supply generator, which, through a rotating power supply transformer 11, 21 supplies energy to the on-board assembly 20. The latter in return gives the physical quantities perceived by the sensors in the form of signals modulated by coded pulses, which then frequency shift modulate a carrier signal transmitted through a rotary signal transformer 22, 12. A receiving head 13 performs the demodulation. Then, the bits 14 are covered and then the cycle synchronization 15, after which the decommutation allows the restitution of the physical quantities in the form of analog signals, as well as their measurement and their recording 17. Application in particular to measurements carried out on a rotating machine.
