Abstract

Fremgangsmåte og anordning for høyhastighets- overfaring av data mellom flere innsamlingsanordninger (Ai) og en sentral stasjon til hvilken de er forbundet via en felles overføringskanal (Vi) for ordrene og en høy- hastighets-overføringskanal (V2) for data. Et første klokkesignal (Hl) tjener til overføring av ordrene, innsamling av data og deres lagring i et minne (10). Et andre klokkesignal (H2) med en høyere frekvens ikke-synkron med den første benyttes til å avlese data lagret av hver innsamlingsanordning. Et bestemt tidsinter- vall (eller vindu) er tilordnet hver anordning, og avlesning av hver lagrede datapakke aktiveres av et ordresignal som indikerer begynnelsen av dette vinduet. - Anvendelse i et seismisk overføringssystem er brukt som eksempel.
