â€œSISTEMA DI COMANDO PER CENTRALI ASPIRANTIâ€ â € œCOMMAND SYSTEM FOR VACUUM UNITSâ €

DESCRIZIONE DESCRIPTION

Il trovato in oggetto riguarda un sistema di accensione e spegnimento degli impianti aspirapolvere centralizzati, sia mono che pluri utenti, realizzato con l'utilizzo combinato della radiofrequenza e delle onde convogliate. The present invention relates to a system for switching on and off centralized vacuum cleaner systems, both single and multiple users, made with the combined use of radio frequency and conveyed waves.

Notoriamente, gli impianti aspirapolvere centralizzati si avvalgono di una centralina collegata, mediante una canalizzazione in plastica sotto traccia oppure in vista, ad una pluralitÃ di prese di aspirazione opportunamente distribuite nelâ€™edificio. Collegando temporaneamente alle suddette prese appositi accessori simili a quelli degli aspirapolvere tradizionali, la polvere ed i rifiuti aspirati vengono convogliati, attraverso la suddetta canalizzazione, nellâ€™apposito contenitore associato alla centralina. It is well known that centralized vacuum systems make use of a control unit connected, by means of an underground or visible plastic channel, to a plurality of suction sockets suitably distributed throughout the building. By temporarily connecting special accessories similar to those of traditional vacuum cleaners to the aforementioned sockets, the dust and waste sucked in are conveyed, through the aforementioned channel, to the special container associated with the control unit.

Esistono giÃ sistemi wireless per lâ€™accensione e lo spegnimento della centralina di un impianto centralizzato, in particolare basati sull'utilizzo della radiofrequenza. Detti sistemi prevedono in linea di massima di applicare, allâ€™impugnatura del tubo aspirante di ogni operatore, un trasmettitore ad onde radio alimentato a batteria, nonchÃ© di utilizzare una pluralitÃ di apparecchi ricevitori, magari disposti ai vari piani da servire e collegati tra loro in parallelo fino al quadro elettrico della centrale aspirante. There are already wireless systems for switching on and off the control unit of a centralized system, in particular based on the use of radio frequency. In principle, these systems provide for the application of a battery-powered radio wave transmitter to the handle of the suction tube of each operator, as well as the use of a plurality of receiving devices, perhaps arranged on the various floors to be served and connected between them in parallel up to the electrical panel of the central vacuum cleaner.

Detta modalitÃ di accensione senza fili ha, perÃ², un limite applicativo dovuto alla schermatura prodotta dalle gabbie di armatura del cemento solitamente presenti nelle pareti e nei solai che il segnale deve attraversare. However, this wireless switch-on mode has an application limit due to the shielding produced by the concrete reinforcement cages usually present in the walls and attics that the signal must pass through.

Scopo del presente trovato Ã ̈ quello di ovviare alla limitazione esposta con un nuovo sistema di accensione e spegnimento di una centrale aspirante, che utilizzi la radiofrequenza in combinazione con la tecnica delle onde convogliate. Tale nuova modalitÃ di accensione puÃ² essere utilizzata anche in quei contesti dove normalmente si installano impianti per piÃ¹ operatori, quali alberghi, ospedali, ecc.. The purpose of the present invention is to obviate the limitation described with a new system for switching on and off a central suction unit, which uses radiofrequency in combination with the conveyed wave technique. This new ignition mode can also be used in those contexts where systems for several operators are normally installed, such as hotels, hospitals, etc.

Lâ€™invenzione verrÃ di seguito illustrata con riferimento ad un disegno allegato, in cui, a solo titolo indicativo e non limitativo, Ã ̈ mostrato schematicamente il nuovo sistema di comando per centrali aspiranti. Come noto, la tecnologia ad onde convogliate Ã ̈ una tecnologia che consente la trasmissione di voce o dati mediante la rete di alimentazione elettrica e si realizza sovrapponendo al trasporto di corrente elettrica, continua o alternata a bassa frequenza, un segnale a frequenza piÃ¹ elevata che Ã ̈ modulato dall'informazione da trasmettere. La separazione dei due tipi di correnti si effettua grazie al filtraggio e separazione degli intervalli di frequenze utilizzate. The invention will be illustrated below with reference to an attached drawing, in which the new control system for central vacuum units is schematically shown, for indicative and non-limiting purposes only. As known, the conveyed wave technology is a technology that allows the transmission of voice or data through the power supply network and is achieved by superimposing on the transport of electric current, direct or alternating at low frequency, a higher frequency signal that It is modulated by the information to be transmitted. The separation of the two types of currents is carried out thanks to the filtering and separation of the frequency ranges used.

Con riferimento alla FIG. 1 , una pompa di aspirazione 1 remota ha mezzi di azionamento elettrico 11 , solitamente un relÃ ̈, che ne controllano il motore elettrico. With reference to FIG. 1, a remote suction pump 1 has electric actuation means 11, usually a relay, which control its electric motor.

Detta pompa di aspirazione 1 Ã ̈ connessa pneumaticamente, mediante tubazioni 12, con una pluralitÃ di prese di aspirazione 13 distribuite nei locali da servire. Collegando temporaneamente alle suddette prese 13 appositi accessori 2 simili a quelli degli aspirapolvere tradizionali, la polvere ed i rifiuti aspirati vengono convogliati, attraverso le suddette tubazioni 12, in un apposito contenitore associato alla pompa 1. Said suction pump 1 is pneumatically connected, by means of pipes 12, with a plurality of suction inlets 13 distributed in the rooms to be served. By temporarily connecting special accessories 2 similar to those of traditional vacuum cleaners to the aforesaid sockets 13, the dust and the sucked waste are conveyed, through the aforementioned pipes 12, to a special container associated with the pump 1.

In particolare, un tubo di aspirazione 20 ha unâ€™estremitÃ dotata di un manicotto 21 impegnabile con la presa di aspirazione 13 in modo da realizzare un collegamento pneumatico tra detto tubo di aspirazione 20 e la pompa di aspirazione 1 attraverso la tubazione 12. In corrispondenza dell'estremitÃ opposta Ã ̈ invece disposta unâ€™impugnatura 22, alla quale fissare gli accessori 23 di volta in volta necessari, quali una prolunga telescopica, una spazzola, ecc.. In particular, a suction pipe 20 has an end equipped with a sleeve 21 which can be engaged with the suction intake 13 so as to make a pneumatic connection between said suction pipe 20 and the suction pump 1 through the pipe 12. corresponding to the opposite end there is instead a handle 22, to which the accessories 23 needed from time to time, such as a telescopic extension, a brush, etc. are fixed.

Detta impugnatura 22 ospita una scheda-trasmettitore 24, integrata o in vista, che comunica, tramite onde radio e quindi wireless, con almeno una scheda 3 detta â€œslaveâ€ , collegata alla linea elettrica di alimentazione a 230V. Le schede slave 3, il cui numero sarÃ determinato dalla portata della scheda trasmettitore, hanno il compito di ricevere il segnale dalla scheda trasmettitore 24 dellâ€™impugnatura 22 e di inviare lâ€™informazione di accensione o spegnimento ad una scheda â€œmasterâ€ 4 attraverso la linea elettrica di alimentazione a 230V, superando i limiti del sistema wireless. Detta scheda master 4, posizionata in prossimitÃ della centrale d'aspirazione od anche integrata nel quadro elettrico in caso di centrali industriali, una volta connessa all'alimentazione elettrica provvede a rilevare il numero di schede slave ed ha il compito di interrogarle per ottenere l'informazione necessaria ad avviare o arrestare l'impianto d'aspirazione, azione che viene attuata tramite il relÃ ̈ 11 presente sulla scheda master ed attraverso appositi cavi 40 di consenso aHâ€™awiamento. Una volta che la scheda master e le schede slave sono connesse alla rete elettrica Ã ̈ possibile diagnosticare la commutazione ad onde convogliate tramite un led posto sulla scheda master. Said handle 22 houses a card-transmitter 24, integrated or in sight, which communicates, via radio waves and therefore wirelessly, with at least one card 3 called â € œslaveâ €, connected to the 230V power supply line. The slave boards 3, the number of which will be determined by the capacity of the transmitter board, have the task of receiving the signal from the transmitter board 24 of the handle 22 and of sending the on or off information to a â € œmasterâ € board 4 through the 230V power supply line, overcoming the limits of the wireless system. Said master card 4, positioned near the suction unit or also integrated in the electrical panel in the case of industrial units, once connected to the power supply, detects the number of slave cards and has the task of interrogating them to obtain the information necessary to start or stop the suction system, an action that is carried out by means of the relay 11 present on the master card and by means of special cables 40 for enabling the start-up. Once the master card and the slave cards are connected to the electrical network, it is possible to diagnose the conveyed wave switching by means of a led placed on the master card.

Il segnale della scheda-trasmettitore 24 puÃ² essere percepito simultaneamente da piÃ¹ schede slave 3, senza che questo generi problemi al sistema. The signal of the transmitter card 24 can be perceived simultaneously by several slave cards 3, without this causing problems to the system.

Una scheda slave 3 comprende i seguenti elementi principali: un modulo ricevitore wireless per ricevere il segnale dalla scheda-trasmettitore 24 ed un modulo ad onde convogliate per trasmettere il segnale sulla linea elettrica. L'alimentazione e la commutazione avvengono tramite alimentazione elettrica a 230V. Le schede slave possono essere in vista oppure integrate a parete all'interno di scatole ad incasso o di derivazione. A slave board 3 comprises the following main elements: a wireless receiver module to receive the signal from the transmitter board 24 and a conveyed wave module to transmit the signal on the electric line. Power supply and switching take place via a 230V power supply. The slave cards can be visible or integrated on the wall inside flush-mounted or junction boxes.

La scheda master 4 comprende i seguenti elementi principali: un modulo ricevitore ad onde convogliate ed un microprocessore di ultima generazione, con memoria a bordo riprogrammabile e software dedicato che converte il segnale ad onde convogliate, proveniente dalla scheda slave, in un segnale logico on/off verso il relÃ ̈ 11 di uscita. The master board 4 includes the following main elements: a conveyed wave receiver module and a latest generation microprocessor, with reprogrammable on-board memory and dedicated software that converts the conveyed wave signal, coming from the slave board, into a logic on / off to relay 11 output.

La scheda master 4 riceve la programmazione dalla scheda trasmettitore 24. Lâ€™alimentazione e la commutazione avvengono tramite il collegamento ad una presa di alimentazione elettrica a 230V. The master card 4 receives the programming from the transmitter card 24. The power supply and the switching take place through the connection to a 230V power supply socket.

E' ovvio che, ferme restando le caratteristiche di massima illustrate e descritte, il sistema di comando ideato potrÃ essere suscettibile di modifiche o varianti comunque comprese nel presente ambito brevettale. It is obvious that, without prejudice to the general characteristics illustrated and described, the control system conceived may be susceptible to modifications or variations, however included in the present patent scope.
