METHOD FOR TRANSMISSION OF MEASUREMENT SIGNAL VIA CURRENT COLLECTOR AND DEVICE FOR ITS REALISATION Russian patent published in 2010 - IPC H01R39/00 H02G11/00 

FIELD: measuring equipment.

SUBSTANCE: in particular, it may be used for transmission of information from rotary object. For this purpose method provides for separation of modulated signal spectra and spectral components of industrial frequency current, noise-eliminating types of sinusoidal signal modulation are used, as well as filtration of modulated sinusoidal signal, galvanic isolation of DC power circuits or industrial frequency current and circuits of measuring signal. Another version - device comprises generator, modulator, matching amplifier, the first and second high-frequency transformers, wire communication line, demodulator, additionally current collector device is introduced with the first and second movable contacts, band-pass filter, two capacitors, source and DC load.

EFFECT: provision of simultaneous, and also alternate transmission of measuring signal and direct current or current of industrial frequency via current collector device with movable contacts for safe working with measuring circuits at the same time.
