Abstract

Inventia se refera la un sesizor optoelectronic în infrarosu, destinat detectarii trecerii prin fata sa a unor corpuri cu suprafata reflectorizanta sau a zonelor absorbante situate pe corpuri cu suprafete reflectorizante. Sesizorul este alcatuit, înprincipal dintr-o dioda electroluminiscenta comandata de impulsuri un fototranzistor care sesiseaza radiatia în infrarosu reflectata un amplificator care amplifica semnalul obtinut de la fototranzistor, un circuit de sesizare a prezentei impulsurilor si un trigger Schmit are comanda tranzistorul de iesire cu colectorul în gol. Sesizorul, utilizat initial pentru sesizarea marcii de pe discul contoarelor de energie electrica poate fi folosit si în alte aplicatii în care se cere sesizarea cu precizie a momentului schimbarii de contrast.The invention relates to an infrared optoelectronic siren detector for detecting the passage of faces with reflective surface or absorbent zones on bodies with reflective surfaces. The sensor consists of a pulse controlled electroluminescent diode, a phototransistor that saturates the infrared radiation reflected an amplifier that amplifies the signal from the phototransistor, a pulse presence sensing circuit, and a Schmit trigger has the output transistor command with the collector in empty. The sensor, initially used to detect the mark on the power meter disc, can also be used in other applications where it is required to accurately sense the moment of contrast change.
