Definitions

  • RFID radio frequency identification technology
  • this invention refers to a device for reading RFID labels automatically which has its own electrical power means for autonomous operation and a light structure equipped with a means for mobility to make it portable in order to facilitate the manual work of reading RFID labels using this device to facilitate its handling by the user.
  • Radio frequency identification technology is based on electronic labels that contain an integrated circuit or chip coupled to a micro antenna.
  • the integrated circuit in the label stores an exclusive code that can be used as a unique identifier for an individual, animal or object.
  • RFID identification devices are known, for example, built into capsules, coins, cards, sheets, etc, but the most usually employed format for identifying products is the self-adhesive label, consisting of various layers of material containing the micro chip connected to the printed circuit antenna, forming an RFlD electronic label that can be placed on the surface of any product.
  • the technical development of radio frequency identification includes RFID devices that can operate in a low frequency band, around 125 kHz, others in the high frequency band at 13.56 MHz, and others developed for working around 900 MHz in the UHF band. Together with the UHF band, the EPC coding standard (Electronic Product Code) has been adopted by the
  • the RFID reader functions as a reading antenna that sends a series of radio waves consisting of an interrogation signal to the RFID electronic label.
  • the RFID labels use the energy of the interrogation signal received from the RFID reader to function and also use the frequency as a synchronisation clock. It is said then that these labels are passive but there is also another type of RFID label called active which requires internal electrical power.
  • the interrogation system can be received by its micro antenna at a distance of up to 10 metres while with active labels it can reach a distance of 30 metres.
  • the tiny antenna in the RFID label sends radio signals containing the unique product code contained in the label's microchip.
  • the reader then sends the code to the computer processing system which carries out the relevant handling of the data received.
  • the user can at any time consult the identity and other information relating to each product, so that, using the computer processing system, he can automatically control and direct the typical production, distribution or sale processes in a company.
  • the computer processing system he can automatically control and direct the typical production, distribution or sale processes in a company.
  • a preferred solution is based on allowing the user to move the reader manually in search of the best position for reading the labels.
  • This invention is designed to solve the problem described above, consisting of a reading device perfectly adaptable to real application environments for radio frequency identification labels (RFID) that increases the effectiveness of the automatic reading of these labels with a device that is handled easily.
  • RFID radio frequency identification
  • this device is based on a body equipped with at least one wheel for its movement which contains an RFID reader connected to an autonomous power supply that allows its operation, according to the user's needs, both when plugged into the electrical mains and without connecting cables that inhibit or limit the body's movement.
  • the autonomous power supply means preferably consists of the well- known UPS or uninterruptible power supply equipment that allows the device to be used continuously even when the mains power supply is cut, also protecting the device from voltage peaks/drops, frequency variations, harmonic distortions, electrical noise and fluctuations that could render it faulty.
  • the body of the proposed reader has at least one tubular arm that allows it to make a complete turn around the axis of its joint with the body. At the opposite end of the joint, that is, its distal end, the arm has a reading antenna that emits the signals generated by the RFID reader within a certain radius. The coverage of the reading antenna can be adjusted electronically.
  • the extension of the arm is also adjustable, configuring it as a telescopic tube or with a flexible part that can be stretched lengthwise.
  • the reader also contains the means to communicate with a local area network (LAN) through which it connects with a central control unit or computer processing system to transmit the information read for its treatment according to the application used by the system.

  • the reader described here is connected via a wireless link to a wireless LAN with the standard 802.11 communications protocol, incorporating for this a wireless transmitter in the body of the device.
  • Some alternative wireless communications protocols are Bluetooth and ZigBee.
  • Another option is its connection to a LAN with a cable, such as the Ethernet network.
  • the central control unit has the storage means for the data read from the RFID labels from which it can obtain other relevant information, for example, for automatically preparing inventories or other necessary reports to control the receipt and/or dispatch of goods or any other service arising from the use of an RFID system.
  • the advantages of using this portable reader are its great versatility, since it can be applied in many situations where a reader with a fixed antenna is ineffective, an increase of productivity in controlling the labelled objects, a reduction of errors and greater performance of the radio frequency identification system, since the reading operation is carried out efficiently and quickly whatever the position and type of RFID labels in the practical case in which the reader described is used.
  • To the advantages of the invention must be added the benefits implied by its use in a complete RFID system, which can be summarised as:
  • the wireless link allows the RFID reader to communicate with the user's information systems, for example, a corporate intranet.
  • the RFID labels facilitate the tracking of products, something which is obligatory in the food sector, providing an identification and continuous supervision during the phases of packaging, storage, dispatch and receipt at the product's final destination.

  • Figure 2 Shows a user handling the device in the previous figure to read the RFID labels of products stored on shelves. PREFERRED FORM OF MANUFACTURING THE INVENTION

  • the body (1 ) of the device also allows a connection to the mains power supply, functioning at 50/60 Hz and a voltage of 110 - 240 V AC with a maximum consumption of 5 A.
  • the operator moves the device in a retail sales establishment or store, bringing the tubular arm (2) with the reading antenna (3) to a minimum distance from each product placed on shelves.
  • the work of reading is carried out very quickly and efficiently, providing an exhaustive control of all the products labelled by radio frequency using simple passes of the "vacuum- cleaner".
  • the simple manual action of the operator serves to control these stocks automatically and effectively because, as the reading is carried out automatically, the available products are easily seen in the shop and possible thefts can be detected, errors reduced, etc.
