RU80255U1 - LABEL FOR IDENTIFICATION OF OBJECTS WITH RADIO INTERFACE - Google Patents

Abstract

A utility model relates to the identification of goods. Its use allows the consumer to determine the characteristics or properties of the acquired object and to find out whether this object was previously identified using the label attached to it. To do this, each object (group of objects) is supplied with a label with a built-in power source and an electronic circuit that stores an individual identification number (IIN), which is also entered into the database, when the object is purchased, the label is activated and the signal from the label memory is transmitted via the tool communication to a personal telecommunication device that transmits the IIN over the communication channel to the database, where the IIN is compared with the numbers stored in the database. In addition, the shortcut has a built-in radio interface, for example, RFID, for recording the TIN in the memory of the shortcut, but this TIN can usually be read only through the shortcut communication tool.

State of the art

US Pat. No. 5,995,898 describes a radio frequency system of a vehicle in which a transponder (14 in FIG. 2) communicates with an on-board computer (12 in FIG. 2). In addition, RFID tags are known that include a 12C data bus - ALB-2480 manufactured by Alien Technology. A Dot microcomputer with RFID interface manufactured by AXCESS International Inc. is available for use.

The closest analogue of the label for this utility model is described in the patent for utility model of the Russian Federation No. 46595. In the description of this utility model, a shortcut is presented with a power source and an electronic circuit including a memory and a communication medium. An individual identification number of the object that is provided with this label is entered in the memory. A means of communication is designed to transfer an individual identification number from memory to a personal telecommunication device when a shortcut is activated. And containing at the same time the usage indicator, made with the ability to change its state when the shortcut is activated.

In the mentioned utility model, the method of storing the identifier in the shortcut memory is not specified.

Utility Model Essence

Thus, the objective of this utility model is to develop such a shortcut for identifying objects that would allow the identifier to be written into the shortcut memory without physical contact with it and after a while to read it only through the means of communication.

To achieve the specified technical result, a shortcut is proposed for identifying an object or group of objects with a radio interface, comprising a power source and an electronic circuit including at least a memory and a communication device interconnected; at the same time, the memory is intended for entering into it an individual identification number assigned to that object or that group of objects that is equipped with this label; The communication tool is designed to transfer an individual identification number from the memory to a personal telecommunications device when the shortcut is activated; a usage indicator configured to change its state upon activation of this shortcut; characterized in that the label contains a radio interface for recording an individual identification number in said memory; some time after recording, an individual identification number is available for review without authentication only through a communication tool.

It is possible that the radio interface contains an RF tag.

Additionally, an individual identification can be transmitted through the means of communication in encrypted form.

Detailed description of utility model

The label for this utility model can be implemented as follows. As the radio interface can be used as a radio frequency tag, and radio modules, for example, ZigBee. A microcontroller, for example, Atmega128, is electrically connected to a microcircuit of a radio frequency transponder, which is part of a radio frequency (RFID) tag with an antenna (or a radio module). This can be done through different interfaces - SPI, parallel bus, I2C, etc. Let it be the I2C bus used in the Alien ALB-2480 RFID tag. The STM TS4956 sound emitter module is connected to the same bus. The microcontroller contains a memory area for the identifier. After the label is made, it generally does not contain useful information. As well as the transponder memory (some vendors write some identifier there, but the high-order bits of the EPC transponder identifier are usually 0). All circuit elements are battery powered. A mechanical button is attached to the microcontroller, when pressed, the microcontroller transmits an object identifier to the sound emitter. And the sound emitter transmits the identifier via the phone in the form of tones.

After the shortcut is installed on the object (for example, a box with software), using a radio frequency reader, a code is remotely stored in the transponder memory, including the object identifier, recording the recording time. In this case, one of the transponder memory bits (for example, the highest one) can be used as a flag, and the other bits as an open additional identifier. The microcontroller periodically scans the transponder's memory, and while the flag is not changed, the microcontroller does not

overwrites information from the transponder's memory. When the flag is changed, it overwrites the identifier transmitted by the radio frequency reader into its memory, and no longer polls the transponder's memory. At the same time, the microcontroller starts the timer program to report the time. After a certain time interval, based on the known period of the microcontroller polling, the radio frequency reader either overwrites the recorded object identifier or enters the second open object identifier there. In another embodiment, the microcontroller may also erase the transponder memory containing the object identifier. The microcontroller can also use a relay to disconnect the RFID antenna from the transponder. In all cases, the object identifier located in the memory of the microcontroller is available for review only through the communication tool. At the moment the button is pressed, the microcontroller sends an encrypted identification number signal to the sound emitter, using the timer value as the key or part of the key. The receiving equipment, knowing the time when the identification code is written in the label, decrypts the number and makes identification, as described in the patent for utility model of the Russian Federation No. 46595.

In some cases, it is convenient to be able to still read the identification number from the memory of the microcontroller using the radio interface. This can be done using a password. The radio frequency reader writes a 96-bit password (the length of the standard EPC code) into the transponder's memory. In this case, the microcontroller still polls the transponder memory, but does not overwrite it until the password appears in the transponder memory. Then the microcontroller copies the identification number to the transponder's memory, and the number can be read over the radio interface.
