The sensor device includes means for sending a remote alarm signal in case of exceeding the predetermined minimum threshold; There? ? usable for multiple purposes, such as alarm for assistance, automatic reorganization of the liquid, activation of an automatic reset system of a minimum permitted level, etc.
L?invenzione si inserisce pi? generalmente nel campo dei dispositivi sensori e/o trasduttori, che inviano a distanza una lettura ed un segnale del dato rilevato. Sono tuttora noti dispositivi misuratori per la determinazione del livello di un liquido in un serbatoio, per esempio in un serbatoio di carburante di veicoli. Essi comprendono solitamente un galleggiante e un'unit? di generazione del segnale fissata al serbatoio. The invention fits more? generally in the field of sensor and/or transducer devices, which remotely send a reading and a signal of the detected data. Measuring devices for determining the level of a liquid in a tank, for example in a vehicle fuel tank, are still known. They usually include a float and a drive unit. of signal generation fixed to the tank.
In pratica, la posizione del galleggiante rispetto all'unit? di generazione del segnale ? convertita in un segnale che ? correlato al livello di riempimento del serbatoio. In practice, the position of the float with respect to the unit? of signal generation ? converted into a signal that ? related to the fill level of the tank.
Tuttavia, i dispositivi di tipo noto sono applicati gi? in fase di produzione dei diversi contenitori, i quali vengono realizzati fin dalla loro produzione iniziale completi di questi sistemi di misura. However, the devices of the known type are already applied in the production phase of the various containers, which are made from their initial production complete with these measuring systems.
Scopo della presente invenzione ? quello di realizzare un dispositivo sensore per la rilevazione di una soglia minima di un materiale solido o di un liquido all?interno di un contenitore, che possa essere inserito in qualsiasi tipo di contenitore (purch? di materiale non completamente schermante elettro-magneticamente), senza prevedere alcuna modifica al contenitore stesso. Purpose of the present invention? that of making a sensor device for detecting a minimum threshold of a solid material or a liquid inside a container, which can be inserted into any type of container (provided that it is not completely electromagnetically shielding material), without foreseeing any modification to the container itself.
Altro scopo dell?invenzione ? quello di realizzare un dispositivo sensore per la rilevazione di una soglia minima di quantit?/livello per materiale solido o liquido all?interno di un contenitore, che possa essere inserito in un contenitore o serbatoio anche successivamente all?installazione originale degli stessi per dotarli di un sistema di rilevamento di livello minimo e tale che possa essere configurato per rilevare il raggiungimento di una soglia minima di livello/quantit? a piacere. Another purpose of the invention? that of creating a sensor device for detecting a minimum quantity/level threshold for solid or liquid material inside a container, which can be inserted into a container or tank even after their original installation to provide them with a minimum level detection system and such that it can be configured to detect the achievement of a minimum level/quantity threshold? to taste.
Come detto il livello minimo pu? riferirsi ad un liquido o ad un materiale solido; in quest?ultimo caso, il dispositivo sensore rileva l?abbassamento del livello conseguente, ad esempio, ad una erosione rispetto ad una superficie di appoggio. As said, the minimum level pu? refer to a liquid or a solid material; in the latter case, the sensor device detects the lowering of the level resulting, for example, from an erosion with respect to a support surface.
Altro scopo dell?invenzione ? quello di realizzare un dispositivo sensore per la rilevazione di una soglia minima di materiale solido o di un liquido contenuto in un contenitore, che sia in grado di funzionare limitando al massimo il consumo di energia per garantire un funzionamento di lunga durata. Another purpose of the invention? that of realizing a sensor device for detecting a minimum threshold of solid material or a liquid contained in a container, which is able to operate by limiting energy consumption as much as possible to ensure long-lasting operation.
Ulteriore scopo dell?invenzione ? quello di realizzare un dispositivo sensore, che sia atto ad inviare a distanza segnali e/o comandi ad un sistema smart-home e/o smart-building di un ufficio e/o edificio e, in particolare, ad inviare un allarme a distanza utilizzabile per molteplici scopi, quali assistenza, riordino automatico del liquido, azionamento di un sistema di ripristino automatico di un livello minimo di liquido consentito, ecc. Further purpose of the invention? that of creating a sensor device, which is capable of remotely sending signals and/or commands to a smart-home and/or smart-building system of an office and/or building and, in particular, to send an alarm at a usable distance for multiple purposes, such as assistance, automatic reordering of the liquid, activation of an automatic reset system of a minimum permitted level of liquid, etc.
Non ultimo scopo dell?invenzione ? quello di realizzare un dispositivo sensore per la rilevazione di una soglia minima di materiale solido o di un liquido contenuto all?interno di un contenitore, che sia facile, veloce e pratico da utilizzare per l?utilizzatore finale, per il fornitore dei servizi di assistenza e per il costruttore del sensore stesso. Not the last purpose of the invention? that of creating a sensor device for detecting a minimum threshold of solid material or a liquid contained inside a container, which is easy, fast and practical to use for the end user, for the assistance service provider and for the manufacturer of the sensor itself.
Questi e altri scopi sono raggiunti da un dispositivo sensore per la rilevazione di una soglia minima di materiale solido o di un liquido contenuto all?interno di un contenitore, secondo la rivendicazione 1 allegata; ulteriori dettagli tecnici e caratteristiche sono riportati nelle ulteriori rivendicazioni dipendenti. La presente invenzione verr? ora descritta, a titolo illustrativo, ma non limitativo, secondo una sua forma preferita di realizzazione, facendo riferimento ai disegni allegati, in cui: These and other aims are achieved by a sensor device for detecting a minimum threshold of solid material or of a liquid contained inside a container, according to the attached claim 1; further technical details and characteristics are reported in the further dependent claims. This invention will come now described, for illustrative but not limiting purposes, according to a preferred embodiment thereof, with reference to the attached drawings, in which:

Si badi innanzitutto che, anche se nella descrizione seguente e nei disegni allegati si fa riferimento all?impiego del dispositivo sensore all?interno di un contenitore per acqua da uffici o inserito in un agglomerato di materiale solido generico, il dispositivo sensore oggetto della presente invenzione pu? essere utilizzato analogamente e con la stessa logica di funzionamento per materiali solidi degradabili (in cui il dispositivo sensore pu? essere conficcato in posizione verticale, come mostrato nella fig. 6 allegata) o inserito all?interno di silos, serbatoi di sostanze chimiche (quali serbatoi di piscine, contenenti cloro e acido), serbatoi di sostanze naturali (quali vino, birra, ecc.) e/o contenitori in genere. First of all, it should be noted that, even if in the following description and in the attached drawings reference is made to the use of the sensor device inside a container for office water or inserted in an agglomeration of generic solid material, the sensor device object of the present invention can? be used analogously and with the same operating logic for solid degradable materials (in which the sensor device can be stuck in a vertical position, as shown in the attached fig. 6) or inserted inside silos, tanks of chemical substances (such as swimming pool tanks, containing chlorine and acid), tanks of natural substances (such as wine, beer, etc.) and/or containers in general.
In ogni caso, rimane interessante l?applicabilit? del dispositivo sensore oggetto dell?invenzione a sistemi originariamente privi di questo tipo di allarme a distanza, senza modificare nulla sul contenitore, sul serbatoio o sul materiale originario. In any case, remains interesting l?applicability? of the sensor device object of the invention to systems originally without this type of remote alarm, without modifying anything on the container, on the tank or on the original material.
Con riferimento alle fig. 1-4 allegate, il dispositivo sensore secondo la presente invenzione comprende un involucro esterno 10, preferibilmente di forma sostanzialmente cilindrica, che, nella versione per il galleggiamento sulla superficie di liquidi 17, contiene una massa 11 atta a definire e forzare un galleggiamento in posizione verticale del dispositivo sensore. With reference to figs. 1-4 annexed, the sensor device according to the present invention comprises an outer casing 10, preferably substantially cylindrical in shape, which, in the version for floating on the surface of liquids 17, contains a mass 11 suitable for defining and forcing a floating in position vertical of the sensor device.
In altre forme di realizzazione della presente invenzione, la massa 11 pu? essere collocata all?esterno dell?involucro 10, attorno ad un?asta verticale o tirante 22, accorciabile a piacere e posta in corrispondenza dell?asse verticale X dell?involucro 10. In ulteriori forme di realizzazione dell?invenzione (fig. 5), la massa 11 non ? necessaria, perch? il dispositivo sensore ? costretto in posizione verticale grazie ad un fissaggio effettuato tramite una zavorra 21, che ? posta sul fondo del contenitore e che ? agganciata all?involucro 10 tramite l?asta verticale o tirante 22, accorciabile a piacere e posta in corrispondenza dell?asse verticale X dell?involucro 10 (come mostrato nelle fig. 1 e 5 allegate). In other embodiments of the present invention, mass 11 can be placed outside the casing 10, around a vertical rod or tie rod 22, which can be shortened as desired and placed in correspondence with the vertical axis X of the casing 10. In further embodiments of the invention (fig. 5) , mass 11 not ? necessary, why? the sensor device ? forced in a vertical position thanks to a fixing made through a ballast 21, which ? placed on the bottom of the container and that ? hooked to the casing 10 via the vertical rod or tie rod 22, which can be shortened as desired and placed in correspondence with the vertical axis X of the casing 10 (as shown in the attached figs. 1 and 5).
In pratica, nelle versioni utilizzate per il galleggiamento sulla superficie di liquidi 17 menzionate in precedenza, l?involucro 10 del dispositivo sensore, secondo la presente invenzione, ? inserito all?interno di un contenitore 15 di liquidi 17 in posizione di galleggiamento superficiale tramite la massa 11 (che definisce un equilibrio di galleggiamento verticale) oppure ? posto in posizione sospesa e l?immersione verticale nel liquido 17 ? mantenuta tramite l?aggancio alla zavorra 21. In practice, in the previously mentioned versions 17 used for floating on the surface of liquids, the casing 10 of the sensor device, according to the present invention, is inserted inside a container 15 of liquids 17 in surface floating position through the mass 11 (which defines a vertical floating equilibrium) or ? placed in a suspended position and the vertical immersion in the liquid 17 ? maintained through the coupling to the ballast 21.
Vantaggiosamente, all?interno dell?involucro 10 e da parte opposta rispetto alla massa 11 o alla zavorra 21, ? posto un supporto 12 contenente una batteria o circuito di alimentazione ed un circuito elettronico di funzionamento del dispositivo sensore; il supporto 12 presenta un?appendice anulare o cilindrica conduttiva 13, disposta in verticale lungo la parete interna dell?involucro 10 e connessa ai circuiti elettronici di alimentazione e funzionamento del dispositivo. Advantageously, inside the casing 10 and on the opposite side with respect to the mass 11 or the ballast 21, placed a support 12 containing a battery or supply circuit and an operating electronic circuit of the sensor device; the support 12 has a conductive annular or cylindrical appendix 13, arranged vertically along the inner wall of the casing 10 and connected to the electronic supply and operating circuits of the device.
Ancora vantaggiosamente, al supporto 12 ? altres? fissato un pendolo metallico 14, che ? connesso ai circuiti elettronici di alimentazione e di funzionamento del dispositivo sensore; il pendolo metallico 14 ? posto centralmente all?interno dell?involucro 10, ? libero di oscillare e, in condizioni di riposo, non contatta l?appendice anulare o cilindrica 13. Still advantageously, to support 12 ? otherwise? fixed a metal pendulum 14, which ? connected to the power supply and operating electronic circuits of the sensor device; the metallic pendulum 14 ? located centrally inside the casing 10, ? free to oscillate and, in rest conditions, does not contact the annular or cylindrical appendix 13.
Secondo altre forme di realizzazione dell?invenzione, l?involucro 10 del dispositivo sensore ? inserito, in posizione verticale, all?interno di un materiale solido degradabile 20 (come mostrato nella fig. 6 allegata). In ogni caso, quando il materiale solido 20 viene eroso o quando il liquido 17 raggiunge una soglia minima prefissata all?interno del contenitore 15, l?asse X dell?involucro 10 del dispositivo sensore si inclina rispetto all?asse verticale Y del contenitore 15 (in caso di utilizzo di un contenitore 15 di liquidi 17 e senza l?impiego della zavorra 21, come mostrato nelle fig. 1-4 allegate) o rispetto all?asse verticale X1 dello stesso involucro 10 in condizioni di riposo (in caso di impiego in materiali solidi 20 e/o in caso di utilizzo della zavorra 21, come mostrato nelle fig. 5-6 allegate, ove le posizioni di riposo e di allarme sono indicate, rispettivamente, con i riferimenti 19 e 18) con un angolo che determina un contatto tra il pendolo 14 e l?appendice anulare o cilindrica 13. According to other embodiments of the invention, the casing 10 of the sensor device is inserted, in a vertical position, inside a solid degradable material 20 (as shown in the attached fig. 6). In any case, when the solid material 20 is eroded or when the liquid 17 reaches a pre-set minimum threshold inside the container 15, the X axis of the casing 10 of the sensor device tilts with respect to the vertical Y axis of the container 15 (in case of use of a container 15 of liquids 17 and without the use of the ballast 21, as shown in the attached figs. 1-4) or with respect to the vertical axis X1 of the same casing 10 in rest conditions (in case of use of solid materials 20 and/or in case of use of the ballast 21, as shown in the attached Figs. 5-6, where the rest and alarm positions are indicated, respectively, with the references 19 and 18) with an angle which determines a contact between the pendulum 14 and the annular or cylindrical appendage 13.
Tale contatto chiude il circuito di alimentazione del supporto 12 collegando la batteria al circuito elettronico e determinando cos? l?accensione di un sistema radio trasmittente previsto nei circuiti di funzionamento del dispositivo sensore ed il conseguente invio, via radio, di un segnale di allarme da parte dei circuiti elettronici di funzionamento posti all?interno del supporto 12. This contact closes the power supply circuit of the support 12 by connecting the battery to the electronic circuit and thus determining? the switching on of a radio transmitter system provided in the operating circuits of the sensor device and the consequent sending, via radio, of an alarm signal by the electronic operating circuits placed inside the support 12.
Vantaggiosamente, il segnale di allarme pu? essere inviato a distanza, via wireless, ad un sistema smarthome di un ufficio e/o edificio in generale per molteplici scopi, come una richiesta di assistenza, un riordino automatico del liquido 17 contenuto nel contenitore 15, l?azionamento di un sistema di ripristino automatico di un livello minimo del liquido 17 all?interno del contenitore 15, ecc. Advantageously, the alarm signal can be sent remotely, via wireless, to a smarthome system of an office and/or building in general for multiple purposes, such as a request for assistance, an automatic reordering of the liquid 17 contained in the container 15, the activation of a reset system automatic control of a minimum level of the liquid 17 inside the container 15, etc.
In particolare, nella forma di realizzazione illustrata nella fig. 5 allegata, ? possibile fissare il dispositivo sul fondo del contenitore 15, in modo che rimanga sospeso in immersione, in condizione di riposo, ad una certa distanza da un livello superficiale L1 del liquido 17. Anche in questo caso, ? possibile utilizzare un?asta o tirante 22, accorciabili a piacere, per decidere un livello di quota minima L2 di liquido 17 all?interno del contenitore 15, inferiormente alla quale l?asse X dell?involucro 10 si inclina di un certo angolo, rispetto all?asse verticale X1 dello stesso involucro 10 in posizione di riposo, determinando cos? una condizione di allarme. In particular, in the embodiment illustrated in fig. 5 attached, ? It is possible to fix the device on the bottom of the container 15, so that it remains suspended submerged, in rest condition, at a certain distance from a surface level L1 of the liquid 17. It is possible to use a rod or rod 22, which can be shortened as desired, to decide a minimum level L2 of liquid 17 inside the container 15, below which the X axis of the casing 10 tilts by a certain angle, with respect to the vertical axis X1 of the same casing 10 in rest position, thus determining? an alarm condition.
Gli esempi illustrati nelle figure allegate evidenziano come, nelle condizioni di riposo assunte dall?involucro 10 del dispositivo sensore, non vi sia consumo di corrente (come, per esempio, nelle condizioni di riposo illustrate nelle fig. 2-3 allegate). The examples illustrated in the attached figures show how, in the rest conditions assumed by the casing 10 of the sensor device, there is no current consumption (as, for example, in the rest conditions illustrated in the attached figs. 2-3).
Infatti, in modo vantaggioso, il dispositivo sensore oggetto dell?invenzione consuma energia (prelevata dalla batteria di alimentazione contenuta nel supporto 12) solo in condizioni di allarme, vale a dire solo nel momento in cui il pendolo 14 contatta l?appendice anulare o cilindrica 13; di conseguenza, la batteria di alimentazione potr? avere una lunga durata essendo scollegata per tutto il tempo in cui non vi ? una condizione di allarme. In fact, advantageously, the sensor device object of the invention consumes energy (taken from the power supply battery contained in the support 12) only in alarm conditions, i.e. only when the pendulum 14 contacts the annular or cylindrical appendage 13; as a result, the power battery will be able to have a long life being disconnected for all the time in which there ? an alarm condition.
Vantaggiosamente, in alternativa o in combinazione alle forme di realizzazione descritte, all?interno del supporto 12 possono essere previsti, se necessario, ulteriori sensori e/o trasduttori atti a rilevare altri parametri, oltre al livello minimo di materiale solido 20 o di liquido 17 prefissato. Advantageously, as an alternative to or in combination with the embodiments described, further sensors and/or transducers can be provided inside the support 12, if necessary, suitable for detecting other parameters, in addition to the minimum level of solid material 20 or liquid 17 set.
In particolare, possono essere previsti, per esempio, sensori di temperatura del liquido 17 o del materiale solido 20 ove il dispositivo sensore ? inserito o immerso, torbidit? e/o limpidezza del liquido 17, qualit? del liquido 17 (al fine di effettuare, per esempio, un?analisi dei solidi disciolti totali (TDS) nel caso di acqua), pH del liquido 17. In particular, sensors for the temperature of the liquid 17 or of the solid material 20 can be provided, for example, where the sensor device ? inserted or immersed, turbidity? and/or clarity of the liquid 17, quality? of liquid 17 (in order to carry out, for example, an analysis of total dissolved solids (TDS) in the case of water), pH of liquid 17.
Sempre in modo vantaggioso, i circuiti elettronici di funzionamento del dispositivo sensore possono includere appositi mezzi di identificazione univoca per la tracciabilit? del contenitore 15 entro cui il dispositivo sensore ? inserito. Still advantageously, the electronic operating circuits of the sensor device can include suitable univocal identification means for traceability? of the container 15 within which the sensor device ? inserted.
In tutti questi casi, ovviamente, il consumo della batteria sar? di conseguenza superiore a quanto descritto in precedenza. In all these cases, obviously, the consumption of the battery will be? consequently higher than described above.
Dalla descrizione effettuata sono chiare le caratteristiche del dispositivo sensore per la rilevazione di una soglia minima di materiale solido o di un liquido contenuto all?interno di un contenitore, cos? come chiari ne risultano i vantaggi. From the description given, the characteristics of the sensor device for detecting a minimum threshold of solid material or of a liquid contained inside a container are clear, as well as how clear are the advantages.
