Abstract

Razvijen je i realiziran nosivi sustav za mjerenje propulzivne sile generirane tijekom plivanja u bazenu. Odašiljački uređaj pojačava, obrađuje i digitalizira izmjereni signal tenzometarskog pretvornika sile i šalje podatke bežičnom komunikacijom na prijemnik u stacionarnom dijelu sustava na rubu bazena. Tenzometarski pretvornik ugrađen je na čelično uže koje plivač tijekom plivanja vuče za sobom, a čija se napetost regulira. Plivač oko struka nosi remen na koji je to uže pričvršćeno. Za vrijeme mjerenja uže treba održavati napetim što se postiže korištenjem električne kočnice u stacionarnom dijelu sustava. Prijemnik omogućuje prikaz izmjerenih podataka u stvarnom vremenu i njihovu pohranu na računalo.

Abstract (english)

Wearable swimming propulsion force measurement system was designed and developed. Transmitting device performs analog signal processing and samples the signal from the strain-gauge sensor. The data is transmitted to the receiver located by the edge of the swimming pool. Load-cell is built-in into the steel rope which is towed through the measurement process. Tension of the rope is adjustable. Swimming athlete wears a belt to which the rope is attached to. During the measurement process the rope must be tense and to achieve that the electric clutch is used. Receiver displays and logs the real time data.
