Description

DESCRIZIONE DESCRIPTION

L'ADATTATORE DI IMPEDENZA PER SISTEMI TRASMISSIVI DIGITALI CON SEGNALAZIONE OTTICA AUTOALIMENTATA PREVEDE UNA CIRCUITAZIONE ELETTRONICA PER ACCENDERE I LED DI SEGNALAZIONE PRESENZA FLUSSO NUMERICO, QUESTA È ESSENZIALMENTE COSTITUITA DA UN CIRCUITO TRIPLICATO RE DI TENSIONE OVVIAMENTE OPERANTE, DATO IL TIPO DI SEGNALE, IN ALTA FREQUENZA. UNA PICCOLISSIMA QUANTITÀ DI ENERGIA VIENE PRELEVATA, IN ALTA IMPEDENZA DAGLI IMPULSI DEL SEGNALE, TRAMITE UN RESISTORE NON INDUTTIVO E INVIATO A UN CIRCUITO TRIPLI CATORE DI TENSIONE UTILIZZANTE COMPONENTISTICA, DIODI E CONDENSATORI, ADATTI PER OPERARE IN ALTA FREQUENZA. ALL'USCITA DEL TRIPLI CATORE È PRESENTE UNA TENSIONE CONTINUA CHE INVIATA AL LED, TRAMITE UN RESISTORE PER OTTIMIZZARE LA CORRENTE ASSORBITA, NE PROVOCA L'ACCENSIONE. I DIODI UTILIZZATI NEL TRIPLI CATORE SONO DEL TIPO SCHOTTKY A BASSISSIMA CADUTA DI TENSIONE E PER FREQUENZE DI LAVORO ELEVATE IN MANIERA DA AVERE UN ALTO RENDIMENTO DEL TRIPLI CATORE. IL DIODO LED UTILIZZATO È A BASSISSIMA CORRENTE DI INNESCO, DELL'ORDINE DI POCHI MICROAMPERE CONTRIBUENDO QUINDI ANCH'ESSO A MANTENERE ALTO IL RENDIMENTO DEL CIRCUITO. TUTTA LA COMPONENTISTICA È DEL TIPO IN SMD PER CONTENERE AL MINIMO LE COMPONENTI INDUTTIVE DEL CIRCUITO. THE IMPEDANCE ADAPTER FOR DIGITAL TRANSMISSION SYSTEMS WITH SELF-POWERED OPTICAL SIGNALING PROVIDES AN ELECTRONIC CIRCUITATION TO TURN ON THE NUMERICAL FLOW SIGNALING LEDS, THIS IS ESSENTIALLY CONSTITUTED BY A TRIPLE VOLTAGE RETURN CIRCUIT, WHICH IS ESSENTIALLY CONSISTING OF A TRIPLICATE SENSITIVE CIRCUIT, . A VERY SMALL AMOUNT OF ENERGY IS WITHDRAWAL IN HIGH IMPEDANCE FROM THE SIGNAL IMPULSES, THROUGH A NON-INDUCTIVE RESISTOR AND SENT TO A TRIPLE VOLTAGE CATOR CIRCUIT USING COMPONENTS, DIODES AND CAPACITORS, SUITABLE FOR OPERATING AT HIGH FREQUENCY. AT THE OUTPUT OF THE TRIPLE CATOR THERE IS A CONTINUOUS VOLTAGE WHICH SENT TO THE LED, THROUGH A RESISTOR TO OPTIMIZE THE ABSORBED CURRENT, CAUSES IT TO IGNITION. THE DIODES USED IN THE TRIPLE CATOR ARE OF THE SCHOTTKY TYPE WITH VERY LOW VOLTAGE DROP AND FOR WORKING FREQUENCIES HIGH TO HAVE A HIGH EFFICIENCY OF THE TRIPLE CATOR. THE LED DIODE USED IS AT A VERY LOW INITIATION CURRENT, IN THE ORDER OF A FEW MICROAMPS, THUS HELPING TO KEEP THE CIRCUIT PERFORMANCE HIGH. ALL THE COMPONENTS ARE OF THE SMD TYPE TO CONTAIN THE INDUCTIVE COMPONENTS OF THE CIRCUIT AT A MINIMUM.

OVVIAMENTE NELL'ADATTATORE SONO PRESENTI DUE CIRCUITAZIONI DEL TUTTO IDENTICHE, OPERANTI UNA IN TRASMISSIONE E UNA IN RICEZIONE, CHE PILOTANO I DUE LED SEGNALANTI UNO IL FLUSSO NUMERICO IN TRASMISSIONE E L'ALTRO IN RICEZIONE. LA SEGNALAZIONE OTTICA DELL'ADATTATORE È ATTIVA IN UN RANGE DI FREQUENZA CHE VA DA ALCUNE CENTINAIA DI KBIT/S FINO A 34 M BIT/S MA L'UTILIZZO DELL'ADATTATORE PUÒ ESSERE ESTESO FINO A 155 M BIT/S IN QUANTO LA SUA INSERZIONE NON DETERMINA CHE SI CREINO ERRORI NELLA TRASMISSIONE DEL SEGNALE RISPETTANDO COSÌ LA ITU-T RACCOMANDAZIONE G703 (SERIES G: TRANSMISSION SYSTEM AND MEDIA, DIGITAL SYSTEMS AND NETWORKS). OBVIOUSLY, IN THE ADAPTER THERE ARE TWO COMPLETELY IDENTICAL CIRCUITIONS, ONE OPERATING IN TRANSMISSION AND ONE IN RECEPTION, THAT DRIVE THE TWO LEDS, ONE SIGNALING THE NUMERICAL FLOW IN TRANSMISSION AND THE OTHER IN RECEIVING. THE OPTICAL SIGNALING OF THE ADAPTER IS ACTIVE IN A FREQUENCY RANGE THAT GOES FROM A FEW HUNDREDS OF KBIT / S UP TO 34 M BIT / S BUT THE USE OF THE ADAPTER CAN BE EXTENDED UP TO 155 M BIT / S AS ITS INSERTION DOES NOT DETERMINE ERRORS IN SIGNAL TRANSMISSION, THUS COMPLYING WITH ITU-T RECOMMENDATION G703 (SERIES G: TRANSMISSION SYSTEM AND MEDIA, DIGITAL SYSTEMS AND NETWORKS).

Claims (6)

RIVENDICAZIONI 1. ADATTATORE DI IMPEDENZA CARATTERIZZATO DAL FATTO CHE, MEDIANTE UN CIRCUITO ELETTRONICO, IMPLEMENTA UN SISTEMA DI SEGNALAZIONE OTTICA DELLA PRESENZA DEL FLUSSO NUMERICO, PER MEZZO DI EMETTITORI LUMINOSI, SIA PER IL CANALE TRASMISSIVO SIA PER QUELLO RICETTIVO, SENZA L'AUSILIO DI ALIMENTAZIONE ESTERNA. CLAIMS 1. IMPEDANCE ADAPTER CHARACTERIZED BY THE FACT THAT, THROUGH AN ELECTRONIC CIRCUIT, IMPLEMENTS A SYSTEM OF OPTICAL SIGNALING OF THE PRESENCE OF NUMERICAL FLOW, BY MEANS OF LUMINOUS EMITTERS, BOTH FOR THE CHANNEL TRANSMISSIVE BOTH FOR THE RECEPTIVE ONE, WITHOUT THE AID OF EXTERNAL POWER SUPPLY. 2. ADATTATORE DI IMPEDENZA SECONDO LA PRIMA RIVENDICAZIONE, CHE PRESENTA SIA PER IL CANALE BILANCIATO CHE PER QUELLO SBILANCIATO UN QUALSIASI TIPO DI CONNETTORE ELETTRICO. 2. IMPEDANCE ADAPTER ACCORDING TO THE FIRST CLAIM, THAT PRESENTS BOTH FOR THE BALANCED CHANNEL AND FOR THAT UNBALANCED ANY KIND OF ELECTRICAL CONNECTOR. 3. ADATTATORE DI IMPEDENZA SECONDO LA PRIMA RIVENDICAZIONE, IDONEO PER QUALSIASI TIPO DI PROTOCOLLO TRASMISSIVO. 3. IMPEDANCE ADAPTER ACCORDING TO THE FIRST CLAIM, SUITABLE FOR ANY KIND OF TRANSMISSION PROTOCOL. 4. ADATTATORE DI IMPEDENZA SECONDO LA PRIMA RIVENDICAZIONE, IDONEO PER QUALSIASI VALORE DI IMPEDENZA. 4. IMPEDANCE ADAPTER ACCORDING TO THE FIRST CLAIM, SUITABLE FOR ANY IMPEDANCE VALUE. 5. ADATTATORE DI IMPEDENZA SECONDO LA PRIMA RIVENDICAZIONE, COSTRUITO SINGOLARMENTE 0 CONTENUTO IN PANNELLI MULTICANALE. 5. IMPEDANCE ADAPTER ACCORDING TO THE FIRST CLAIM, BUILT INDIVIDUALLY OR CONTENT IN PANELS MULTICHANNEL. 6. ADATTATORE DI IMPEDENZA SECONDO LA PRIMA RIVENDICAZIONE, ALLOGGIATO IN CONTENITORI DI QUALSIASI FORMA E MATERIALE.6. IMPEDANCE ADAPTER ACCORDING TO THE FIRST CLAIM, STORED IN CONTAINERS OF ANY SHAPE AND MATERIAL.
