Abstract

Inventia se refera la o metoda si un dispozitiv de teletransmisie a semnalelor livrate de cel putin un traductor alimentat cu energie si conectat la o linie de teletransmisie si consta în aceea ca energia necesara alimentarii traductorului este transmisa prin linie, sub forma de curent alternativ de intensitate în mod sensibil constanta, numita linie îndeplinind tripla functie de furnizare de energie traductorului semnalelor de informatii provenind de la acesta. Dispozitivul cuprinde, în principal, cel putin o linie de transmisie bifilara, alimentata în curentul alternativ, alimentata în curentul alternativ si continînd cîte un transformator la fiecare din extremitatile ei. El cuprinde, în afara de acesta, cel putin un traductor, alimentat cu energie, de fiecare linie de transmisie, precum si unitatea centrala de contril si de prelucrare informatizata, cel putin un modulator-demodulaor, conectat, pe de o parte, la transformatorul situat la o extremitate a fiecarei linii de transmisie si cel putin un modulator-demodulator, conectat la transformatorul situal la cealalta extermitate a fiecarei linii de transmisie, fiecare traductor fiind conectat la fiecare modulator-demodulator, conectat la cealalta extremitate a fiecarei linii de transmisie.
