摘要

The work presents a method of at once power and information transmission through pair of rails using SURPS (Smart Ultrasonic Resonant Power System). The solution allows to (electrically) feed sensors located in hardly accessible places of mechanical constructions with simultaneous half-duplex data transmission (e.g. measurement "question-response"), when conventional power supply (requiring e.g. electricity networks, storage batteries, batteries, etc.) is eliminated. The mechanism of power transmission consists in "sending" of mechanical energy through an actuator in a form of "pure" sinusoidal ultrasonic wave and next "receiving" it and transforming into useful electrical current by a harvester. Both magnetostrictive and piezoelectric harvesters/actuators were used. For information transfer F2F (frequency - double frequency) procedures were used, they are a kind of FM (Frequency Modulation). To optimise transmission (the highest possible efficiency and acceptably low noise level), software allowing to select the right type of an actuator, modulation and the recommended frequency band was developed. Additionally it is possible to determine resonance frequency for each construction which is to be used for information and power transfer.
