Definitions

  • the present invention concerns a high speed system for electronic identification of livestock.
  • the invention refers to a high speed system for electronic identification of livestock by radiofrequency (Rfid), making use of low perceptive impact modular flexible antennas.
  • the invention refers to the productive line of livestock for commerce (e.g. sheep, oxes, swines), wherein it is necessary to individually identify each animal for purposes of food chain tracing.
  • livestock for commerce e.g. sheep, oxes, swines
  • an "inductive” technology is used, based on the use of a medium frequency (i.e. 134,2 kHz) electromagnetic signal (carrier) for the transmission of information without any contact.
  • a medium frequency (i.e. 134,2 kHz) electromagnetic signal (carrier) for the transmission of information without any contact.
  • the transmission of information is obtained through modulation of the carrier by a transponder associated to each animal, the transponders accessing the carrier one by one.
  • transponders modulate the carrier with the univocal numeric code contained in its memory, replying with such a signal to the receiving device.
  • the carrier transmitted by the receiving device allows to remotely feed the transponder associated with the animal forming the object of identification.
  • bioglass transponder endoruminal bolus, ear marking
  • endoruminal bolus oriented according to the axis of maximum coupling between the antennas, can be read, does not go beyond 100 cm and varies as a function of the dimensions and form reading antenna. Only according to some particular configurations, with planar antennas connected in parallel, it is possible to create reading fields up to 130 cm width.
  • the passage in order to minimise the percentage of unread transponders, the passage must be sufficiently narrow, with reference to the dimension of the animals subject to identification.
  • control electronics is designed in order to maximise the intensity of the emitted electromagnetic field, within the limits according to the law. Th e consequence is a high consumption of electric power by the control devices.
  • a possible choice is that of supplying devices from the network (110-240 Vac, 50-60 Hz), but this choice involves two main problems: (a) the getting into the circuit of the electric noise of the network; (b) the wiring of difficult environments such as slaughterplants and and stock farms, with the consequent technical and economic problems.
  • big antennas for emitting intense electromagnetic fields within an important volume have the drawback of collecting also a lot of electromagnetic noise present in the installation environment.
  • a slaughterhouse is an environment with many electromagnetic noise and tension peaks on the feeding lines, two to the presence of a lot of metal, water and big motors causing the presence of noise on the feeding lines.
  • Solutions are also known making use of planar antennas of the flexible kind, that can be positioned vertically below the ceiling of the passage that must be passed by the animals, side by side according to a transversal direction with respect to the path of the animals and constituted by a structure made of a plastic material inside which copper coils are immersed, constituting the inductor in air or wrapped around ferrite.
  • This solution from one hand present a structure that does not limit the width of the passage or the intensity of the emitted electromagnetic field, but on the other hand does not solve the problem of the perceptive impact for the animal passing through the passage.
  • This element is crucial, because all the systems used until today for the radioidentification of livestock present obstacles and dimensional limits for the passage of livestock. That implies, in the specific case of the identification of sheep, an important negative impact on the transit speed of groups. This problem is particularly felt for example in the auctions and slaughterhouses. In both cases, in fact, the fluxes of passage are particularly high and often exceed eight animals per second with passages of more than two metres. In these conditions, any system making the passage slower is practically inapplicable. This is today one of the biggest obstacles to the massive use of RFID for the automatic identification of sheep.
  • the purpose of the present invention is therefore that of realising a system for the electronic identification of livestock that allows to overcome the limits of the solutions according to the prior art and to obtain the previously described technical results.
  • a further aim of the invention is that said system for the electronic identification can be realised with substantially low costs, both with reference to production costs abd management costs.
  • Not last aim of the invention is that of realising a system for the electronic identification of livestock being substantially simple, safe and reliable.
  • a high speed system for electronic identification of livestock comprising one or more low perceptive impact flexible antennas for detection of transponders associated to each animal, arranged vertically in correspondence of a passage for animals to identify, side by side according to a transversal direction with respect to the path of the animals, constituted by a flexible wire supporting at least one cylindrical antenna, and preferably two cylindrical antennas, preferably wrapped around cores of ferrite.
  • said cylindrical antennas can be protected by means of a soft sheath.
  • said flexible antennas comprise means for fixing to the ceiling or to supporting structures.
  • each flexible antenna is contained in a hermetic box to which the antenna is mechanically coupled.
  • said high speed system for electronic identification of livestock is integrated by sensors for detecting the position of each animal in transit, said sensors having the purpose of: (a) determining the number of animals, independently from the presence of identification transponders, (b) mantaining the passage inactive until when no passing animals are present.

  • the high speed system for electronic identification of livestock identified as a whole with the numeric reference 10 consists in an array of flexible antennas 11 arranged transversally with respect to the path of animals 12 to identify.
  • the system is modular since the number and dimension of antennas 11 can vary as a function of the dimensions of the passage and animals 12 to identify.
  • the installation can be made on the ceiling or on suitable suitable supporting structures in a way that allows the flexible antennas 11 can effectively touch the body of animals 12 passing through the passage 13.
  • Animals 12, passing through the passage 13, move apart flexible antennas 11 with no difficulties, the antennas being able to effectively read both transponders contained into the endoruminal boli and those contained in the ear markings.
  • FIG. 1 shows the structure of the flexible antenna 11 used in the proposed modular system.
  • the antenna 11 is characterised by a structure made of plastic material giving it extreme flexibility and softness. Inside the plastic structure 14 are immersed the coils of copper constituting the inductor in air or wrapped over ferrite. Control electronics for each antenna 11 is contained in a sealed container 15 to which the antenna is mechanically coupled. The upper end of such sealed container 15 is structured in a way that allows for a quick and safe fixing to the structure carrier (wall, metallic cross bar, etc.), for example by means of a suitable flange 16.
  • each antenna of the array (11', 11", ..., 11n) is linked to its own control electronics (17', 17", ..., 17n) that make the inductor respond to the frequency o f 1 34,2 kHz, supplying to the transponders the carrier to modulate according to ISO standards 11784 and 11785.
  • This electronics also provides for the amplification and decoding of the signal emitted by transponders.
  • Such electronics further provides for the synchronisation of signals transmitted by means of the antennas in order to avoid that the latter can negatively interact with one another.
  • the described system can find an important application in the electronic identification of animals of reduced dimensions, such as sheep, goats and swines, not suitable for identification by means of traditional planar antennas. In fact, such animals are moved all together and very quickly, and such condition put any passage of a traditional kind in difficulty.
  • the livestock passing through the passage, touch the flexible antennas 11 , which pass very close to the identification transponders maximising the probability of reading, even if the animal is passing quickly and independently from the number of animals passing at the same time.
  • Moving animals move apart flexible antennas, and can also completely lift them up. This determines a dynamic deformation of the electromagnetic field generated by the antennas and as a whole increasing the possibility of reading of the transponders independently from their orientation.
  • the proposed system does not require any dimensional limit of the passage, since it allows for putting side by side different modules 20, consequently being widened until a complete coverage of the passage.
  • the telescopic vertical supports 21 it is possible to put it at any height with respect to the soil, suitably adjusting the length of the hanging down antennas.
  • antennas 11 imply a low perceptive impact because they are seen by the animal 12 as thin filaments sufficiently far from each other that cannot be considered as an obstacle.
  • the hanging down antennas 11 are further colored in order to produce a mimetic effect with the surrounding environment (green, ochre, black).
  • antennas 11 are substantially constituted by a flexible wire 22 containing two cylindrical antennas 23, 23' wrapped around cores of ferrite 24, 24'.
  • the antennas 23 and 23' are protected by means of a soft sheath 25, 25' absorbing the impact with the animal running.
  • the antennas are double, in order to create an electromagnetic field sufficiently long to assure the reading of the transponder even in case of particularly quick passages.
  • Each hanging down antenna produces an electromagnetic field
  • this allows to have electromagnetic fields with reduced cross dimensions, in order not to illuminate two animals passing side by side at the same time, and great longitudinal dimension, in order to illuminate the animal for a time sufficient for the reading of the transponder, also in case of very fast transits.
  • This is a consequence of the fact that, due to the length of the antennas, vertically hanging down, at the passage of livestock antennas are lifted and are positioned in a longitudinal direction on the back of the animal, dynamically following its movements and, in particular, that of its transponder.
  • the system for the electronic identification of livestock has the further advantage of solving the problem of the counting and marking of livestock not provided with identification transponder, because the transponder is out of work or has gone lost.
  • the system can be integrated with the use of suitable sensors that are able to determine the position of each animal passing through the passage, independently from its widht.
  • This sensors can be of optic, acoustic or mechanic kind and their purpose is that of detecting the instantaneous crossing profile animals passing through a section of the passage.
  • a suitable software implemented by a PLC, interprets in real time the information detected by the sensors determining the profile of passing animals. This allows to make a precise count of animals independently from the presence of identification transponders.
  • the system can also associate a transponder detected by means of the reading system and an animal detected by means of the counting system. In this way, knowing their position, the system can identify animals that do not have a transponder. This allows to make a marking in real time of animals without transponders passing through the passage, by means of a real time marking system.
  • This marking system can be implemented by means of an array of sprayers of paint, controlled by the PLC of the passage, which can spray a colored spot on the animals without transponder.
  • a typical non limitative application of the previously described system provides for the implementation of a passage 250 cm widht for the rad ⁇ identification of sheep 12.
  • Flexible vertical antennas 11 are linked to a bar 250 cm long and having a section of 50 cm 2 with an interspace of about 30 cm.
  • Antennas 11 are 60 cm long and the support bar is positioned at about 100 cm from the soil.
  • Antennas are wrapped around a core of ferrite, allowing for reduced dimensions, with respect to antennas wrapped "in air”.
  • the system is constituted by a plurality of crossing bars, each linked to the other.
  • Antennas' control circuit are all synchronised with one another, in order to allow for the use at the same time of the readers notwithstanding the proximity of the antennas and the crosstalking effect.
  • Each antenna 11 is polarised inversely with respect to the neighbours, thus generating a reading field that can be dynamically coupled in the best way with transponders contained in the ear marks of animals 12.
