Description

DESCRIZIONE DESCRIPTION

La presente invenzione ha per oggetto un sistema distribuito di certificazione dei processi produttivi per la produzione di trasformatori elettrici. The present invention relates to a distributed certification system for production processes for the production of electrical transformers.

Ad oggi è piuttosto difficile effettuare un monitoraggio puntuale e rigoroso dei processi produttivi, a partire dal materiale, dal semilavorato al prodotto finale (trasformatore elettrico). Gli stessi enti certificatori e player mondiali ad oggi sono molto esigenti, e non bastano controlli spot e procedure monitorate con checklist cartacee. Infatti, è possibile effettuare una dichiarazione a posteriori con facilità. Ciò fa perdere di rigore al processo produttivo e ne aumenta la competitività di aziende non etiche. Today it is rather difficult to carry out a punctual and rigorous monitoring of the production processes, starting from the material, from the semi-finished product to the final product (electrical transformer). Today the same certification bodies and world players are very demanding, and spot checks and procedures monitored with paper checklists are not enough. In fact, it is possible to make a retrospective declaration with ease. This makes the production process lose its rigor and increases the competitiveness of unethical companies.

L’avvento della blockchain è quindi una ottima soluzione per certificare i processi produttivi dei trasformatori elettrici, monitorando in modo digitale certificato le fasi e i controlli sul materiale utilizzato, il semilavorato prodotto fino alle manutenzioni effettuate sul prodotto finito (trasformatore elettrico). La block-chain ha la sua forza nel sistema distribuito multi-dispositivo, che ne garantisce l’integrità, la disponibilità e la validazione temporale del dato. Tutto si basa sui ledger, registri condivisi che sono immuni da corruzione. Nel suddetto contesto, oggetto della nostra invenzione é essenzialmente quello di effettuare un sistema distribuito di certificazione dei processi produttivi per la produzione di trasformatori elettrici grazie all’utilizzo dell’interfaccia di connettività ad Internet (1) per mezzo di RETE WIFI o Internet Gateway che ne rappresenta il mezzo di comunicazione alla base dell’interconnessione dei dispositivi distribuiti della block-chain; calcolatore elettronico (2) in grado di generare per l’utente in modo intelligente per ciascun tipo di semilavorato (3) e materiale una serie di fasi e controlli da effettuare grazie ad un sistema esperto (9), modulo per la certificazione mediante registrazione su ledger (5) in block-chain (sistema distribuito di calcolatori interconnessi) delle fasi e dei controlli rilevanti del processo produttivo rilevati mediante interfaccia HMI (4), utilizzata dall’operatore al fine di effettuare le registrazioni di fasi e dei relativi controlli proposti dal calcolatore (2). Tutto il processo rilevante viene quindi mappato su ledger (5) ed è possibile in qualsiasi momento ricostruire l’intera storia della produzione di un singolo trasformatore (8) a partire dal materiale impiegato e dal primo operatore intervenuto nel processo produttivo. Il sistema si avvale anche di un modulo (6) per il controllo mediante “computer vision” dell’output prodotto, che ne effettua il controllo di qualità certificato temporalmente su ledger (5). The advent of the blockchain is therefore an excellent solution for certifying the production processes of electrical transformers, by digitally monitoring the phases and controls on the material used, the semi-finished product up to the maintenance carried out on the finished product (electrical transformer). The block-chain has its strength in the multi-device distributed system, which guarantees the integrity, availability and time validation of the data. Everything is based on ledgers, shared ledgers that are immune to corruption. In the aforementioned context, the object of our invention is essentially to carry out a distributed system of certification of production processes for the production of electrical transformers thanks to the use of the Internet connectivity interface (1) by means of WIFI NETWORK or Internet Gateway which it represents the means of communication at the basis of the interconnection of the distributed devices of the block-chain; electronic computer (2) capable of generating for the user in an intelligent way for each type of semi-finished product (3) and material a series of phases and checks to be carried out thanks to an expert system (9), form for certification by registration on ledger (5) in block-chain (distributed system of interconnected computers) of the relevant phases and controls of the production process detected through the HMI interface (4), used by the operator in order to record the phases and related controls proposed by the computer (2). All the relevant process is then mapped on ledger (5) and it is possible at any time to reconstruct the entire history of the production of a single transformer (8) starting from the material used and the first operator involved in the production process. The system also uses a module (6) for the control of the output produced by "computer vision", which carries out the quality control certified temporally on the ledger (5).

Detto sistema è anche utilizzato per correlare al singolo trasformatore tutte le relative manutenzioni e guasti registrati. Ciò viene effettuato mediante il modulo (7) per la registrazione delle manutenzioni effettuate sui singoli trasformatori (8) su ledger (5). This system is also used to correlate all the related maintenance and faults recorded to the single transformer. This is done using the form (7) for recording the maintenance carried out on the individual transformers (8) on ledger (5).

Il tutto consente ad un motore di sintesi presente su un calcolatore esterno (9) chiamato “process controller” di effettuare il controllo del processo certificato mediante ledger (5). All this allows a synthesis engine present on an external computer (9) called "process controller" to control the certified process by means of ledger (5).

Il trasformatore viene quindi caratterizzato da un controllo produttivo che consente all’utente finale di poter effettuare in qualsivoglia momento la verifica dell’intera storia del suo prodotto. Ciò consente di perseguire come società produttrice di trasformatori un notevole vantaggio competitivo in termini di rispondenza alle specifiche, agli standard e di etica aziendale. The transformer is therefore characterized by a production control that allows the end user to be able to check the entire history of his product at any time. This allows us to pursue a significant competitive advantage as a transformer manufacturing company in terms of compliance with specifications, standards and business ethics.

E’ possibile quindi definire l’affidabilità del trasformatore T al tempo t come funzione dei contributi Θ certificazione della correttezza delle fasi e controlli su materiali (m(T)), semilavorati (s(T)) e delle manutenzioni effettuate canoniche e sui guasti registrati (p(T)). It is therefore possible to define the reliability of the transformer T at time t as a function of the contributions Θ certification of the correctness of the phases and checks on materials (m (T)), semi-finished products (s (T)) and on the maintenance carried out canonical and on faults registered (p (T)).

Aff(T,t) = f(Θ(m(T)) , Θ(s(T)) , Θ(p(T))) Aff (T, t) = f (Θ (m (T)), Θ (s (T)), Θ (p (T)))

Mediante l’analisi del fattore di affidabilità grazie ai ledger distribuiti (5), è possibile da parte del controller (9) effettuare una stima nel tempo dell’affidabilità dei processi produttivi aziendali e dei prodotti implementati. Tale sistema esteso a diversi produttori può consentire una sana competizione al fine del perseguimento di standard produttivi notevoli. By analyzing the reliability factor thanks to the distributed ledgers (5), it is possible for the controller (9) to make an estimate over time of the reliability of the company's production processes and the products implemented. This system extended to different producers can allow healthy competition in order to pursue remarkable production standards.
