Description:
SYSTEM AND METHOD FOR THE IDENTIFICATION OF SPECIMENS TAKEN FROM A

CONSTRUCTION AND THEIR UNIQUE CORRELATION WITH THE CONSTRUCTION

DESCRIPTION

Technical field

The present invention relates to the technical field of construction, and particularly it relates to a system and a method for the identification of specimens taken from a construction and the unique correlation thereof with the construction.

State of the Art

During the production of a construction consisting of elements/parts made of concrete or other materials such as metal, wood or composites, whether they are made in situ or manufactured in the factory, it is provided for that there be taken, simultaneously with the production step, specimens which - subjected to testing - bear evidence to the mechanical-physical-chemical features of the material used for the specific production.

Currently, there are techniques and systems which allow to link the samples taken during the production of a construction which are completely manual, bearing - on the specimen and on a container thereof - an identification tag (manual or electronic) showing the data characterising the quality of the material/process such as - by way of non-limiting example - the date of production, person in charge of the works, reference to the delivery note, the position where it was taken. The correlation between the specimens and the parts of the construction to which the specimen of the constituent material corresponds by its nature entails a certain level of uncertainty, subsequently, and thus it is not possible to define with precision the exact position of the structure from which the specimen was taken or the correct identification of the specimen, since it is possible to replace/modify the identification tags.

The current systems provide for that the identification first and then the traceability of the specimen is done either entirely manually, through manual tags applied onto the specimen or on the container thereof or at times through electronic systems, for example with RFID TAGS positioned integrally joined with the specimen.

This entirely manual method may be subject to errors and uncertainties relating to damage to the tag, substitution errors or intentional variation for fraudulent purposes.

The current system, however, does not allow to uniquely and certainly associate the specimen with the part of the construction subject of verification, given that it is a manual system that by its nature is liable to errors and deficiencies. The association occurs through appropriate reports written and signed by the required individuals.

All the information characterising the collecting process is also found on media physically separated from the specimen in question.

Summary of the invention

The technical problem addressed by the invention lies in ensuring the absolute identification and traceability of the specimens and the direct correlation thereof with the part of structure to which they refer.

Such problem is resolved by a system for the identification, traceability and location of specimens taken from a construction consisting of elements/parts made of concrete or other materials such as for example metal, wood or composites and the unique association thereof with the construction by using RFID technology or similar technologies, the system comprising at least two RFID TAGS, one of said TAGS being positioned in the specimen, the other of said TAGS being positioned in the construction from which the specimen/s was/were taken, said RFID TAGS comprising data containing information concerning the date, delivery note number, manufacturer, customer, order number, recipe of the material, drawing reference, geographical position of the construction and/or director of works, wherein the data of both at least two RFID TAGS are immutable so as to prevent subsequent modifications thereof, so that there is a direct and immutable correlation both at the physical and information level between the specimens taken and the part of infrastructure to which they refer.

Suitably, the RFID TAGS may be incorporated in the specimens and/or in the construction so as not to be accessible from the external.

Advantageously, the system may consist of two or more RFID TAGS, whose information contained therein can be retrieved by means of remote reading using special devices.

Preferably, the data contained in the RFID TAGS may be protected by an encryption system.

In a preferred but non-exclusive embodiment, the system may comprise a software platform with a storage unit for storing the RFID TAG data. Thanks to the above, it will be possible to ensure a direct and immutable correlation both at the physical and information level between the specimens taken and the part of infrastructure to which they refer.

The problem of ensuring the direct correlation between the specimen and the identification system at the physical level is overcome given that the identification element (RFID tag) that collects all the data relating to the part of the construction becomes an integral part of the specimen as well as of the part of the construction that the specimen represents given that it is "embedded" in the element as well as in the specimen; the problem of correlating the information characterising the process at the information level is overcome considering that the information present on the identification element (RFID tag) is made immutable, hence preventing subsequent modifications of the written information. Furthermore, the information is securely (encrypted) recorded on a distributed database or on a distributed ledger, for example a blockchain.

The information can be retrieved at any time, by reading the TAG present on the infrastructure, with the certainty that this is true, unique and directly correctable with the outcome of the tests carried out on the sample specimen/s.

Thus, should an investigation be carried out on the quality of a structure, both in case of damage or dispute, the system ensures the truthfulness of the data, the direct congruity thereof and the certainty of the immutability of the information.

In a further aspect, there may be provided for a method for the identification of specimens taken from a construction comprising the steps of:

- providing at least one first RFID tag;

- storing first data in said first RFID tag, said first data relating to information of the construction such as the date, delivery note number, manufacturer, customer, order number, recipe of the material, drawing reference, geographical position of the construction and/or director of the works;

- positioning of said at least one first RFID tag at the specimen so as to uniquely associate the specimen with the construction.

Suitably, there may be provided for the steps of: providing at least one second RFID tag; storing second data in said second RFID tag, said first data relating to information of the construction such as the date, delivery note number, manufacturer, customer, order number, recipe of the material, drawing reference, geographical position of the construction and/or director of the works; positioning of said at least one second RFID tag at the part of the construction to which the taken specimens refer.

Advantageously, the first and/or second provision step may comprise the embedding of the at least one first and/or one second RFID tag in the construction and/or in the specimen so as not to be accessible from the external.

FIG. 2 illustrates a diagram of another embodiment of a construction comprising the TAGS 39-49 applied to the construction and the TAGS 44-48 incorporated in the specimens.

Detailed description of an embodiment

As illustrated in the attached drawings, the system described herein will be particularly useful for uniquely identifying and associating the specimen and the construction, required to confirm the quality characteristics of a product and the direct association thereof with the part of the construction from which they were taken and to which they refer.

The main characteristics of the system are described below.

There may be provided for a hardware system consisting of a pair or more UHF RFID tags or equivalent technology that can be active, semi-passive or passive; the former provide for their own power supply while the latter do not require their own power supply given that they receive the energy they need to operate directly from the reader. These devices are provided with a unique identification system and they allow to contain - therein - a set of information that can be made immutable and that can be read in wireless fashion with external reading systems.

For example, in order to make the RFID tag information immutable, the RFID tags may be non-rewritable.

The set of tags may be customised from the information required for the characterisation of the construction, i.e. by way of non-limiting example:

- date of collection

- time of collection

- person in charge of collection

- environmental conditions at time of collection

- part of the construction to which the specimen/s refers/refer

- location of the point of collection with geographic coordinates

- material supplier data

- delivery note number

- identification number of the TAG/s embedded in the specimen.

The media (TAGS) containing the information characterising the material may be positioned integrally both in the specimen and directly in the construction at the collection area, for example by embedding the TAG in the concrete before it dries, or - in the case of composite materials - by inserting the TAG during the rolling step, embedding it into the matrix.

In order to ensure that the positioning of the TAG does not create discontinuity in the manufactured article, the size of the TAG can be very limited, thus allowing positioning even in critical areas.

The TAG support material may be different depending on the need for compatibility with the material of the construction to be monitored.

A remote reading system that does not interfere with the structure to be monitored, per se known, may uniquely read the information present on the tags both those present in the specimen and those present in the construction.

The information inserted into the TAGS may be certified by the Director of Works or equivalent figure through electronic signature or another method of access to the system.

A software platform may record the data of the specimen and of the infrastructure and it may protect them through an encryption system.

The system allows the identification, traceability and location of the specimens taken from the construction and the unique association thereof with the construction by using RFID technology or similar technologies. The system consists of two or more tags, which may be made of various materials, equipped with RFID technology, which are incorporated both in the specimen and in the part of the construction from which the specimen/s was/were taken.

In figure 1, the reference numerals from 1 to 19 indicates the TAGS applied to the various parts of the construction and the reference numerals from 20 to 38 indicate the TAGS incorporated in the specimens; similarly, in figure 2, which represents a portion of a flyover, reference numerals from 39 to 43 indicate the TAGS applied to the construction and reference numerals from 44 to 48 indicate the TAGS incorporated in the specimens.

The system is characterised in that the tags uniquely bear all data required for the identification of the part of the construction subject of verification - before the installation thereof - such as by way of non-limiting example the date, delivery note number, manufacturer, customer, order number, recipe of the material, drawing reference, geographical position of the article/installation, director of works.

The system consists of two or more tags, whose information contained therein can be retrieved by means of remote reading using special devices.

The system is characterised in that the data borne in the tags are immutable and protected by an encryption system.

The system requires that the data borne on the set of tags be stored on a platform characterised by a distributed database or on a distributed ledger, for example a blockchain, so as to ensure that it can be consumable, traceable and immutable.

The system provides for that other documents protected by an encryption system, such as - according to a non-limiting list - drawings, diagrams, reports, photographs, laser scanner reports, be attached associated to the record regarding the identification of the specimen.
