  In the small wireless communication terminal according to the present invention, the narrow area communication means includes means for generating a two-dimensional code based on the information and means for displaying the two-dimensional code.

  According to the present invention, information communication is performed between a small wireless communication terminal whose display space is difficult to secure and an information terminal having a display means, and information is displayed on the information terminal. The effect that information can be displayed simply is acquired.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. First, a first embodiment of the present invention will be described. FIG. 1 shows the configuration of the small wireless communication terminal 100, and FIG. 2 shows the configuration of the information terminal 200. The small wireless communication terminal 100 is the above-described wireless tag (IC tag, small wireless IC tag) or the like, and displays the information in a format (characters, symbols, figures, etc.) that allows a person to identify the contents of the information. There is no means to do. The information terminal 200 is a mobile phone terminal in this embodiment. FIG. 3 shows how the small wireless communication terminal 100 and the information terminal 200 communicate. Thus, communication between both terminals is performed in a state where the small wireless communication terminal 100 and the information terminal 200 are arranged close to each other.

  The small wireless communication terminal 100 is configured in combination with a part having some function (application). Examples of the application include a system for transferring temperature information acquired from the temperature sensor to a remote server via the small wireless communication terminal 100, and a remote state based on information acquired via the small wireless communication terminal 100 (described later). A lock state, etc.) and a system for displaying the same.

  In the small wireless communication terminal 100 shown in FIG. 1, the control means 101 is composed of a CPU (Central Processing Unit) or the like, and controls each means in the small wireless communication terminal 100. The storage unit 102 simply holds information when temporarily transferring information, or SRAM (Static Random Access Memory), SDRAM (Synchronous Dynamic Random Access Memory), ROM for holding information for a long time (Read Only Memory), EEPROM (Electronically Erasable and Programmable Read Only Memory) and the like, and stores various information.

  The transmission / reception means 103 is composed of an antenna, a transmission / reception circuit, and the like, and communicates with the outside by wireless communication such as a specific low power method or a PDC-P method. The infrared data communication means 104, which is a narrow area communication means, is composed of a light emitting element and a light receiving element for infrared communication, and performs infrared communication with the information terminal 200 by an IrDA (Infrared Data Association) method. The power supply means 105 is composed of a battery or the like and supplies power to each part in the small wireless communication terminal 100.

  The main communication means of the small wireless communication terminal 100 is the transmission / reception means 103. The small wireless communication terminal 100 according to the present embodiment is not used for communication between people but for communication between things (for example, when a vending machine transmits information on change or stock status to a remote monitoring center). This is the main application area. When such a system is operated, the number of objects to which the small wireless communication terminal 100 is attached far exceeds the number of mobile phone terminals that are approximately the same as the population. Therefore, the wireless network with which the transmission / reception means 103 communicates needs to be able to accommodate terminals several to several hundred times the population.

  Unlike a wired network, in order to accommodate a large number of terminals in a wireless network with a large band resource limit, it is important how efficiently communication traffic can be accommodated. For example, the destination terminal ID field in the header can be omitted by fixing the communication partner. In addition, in the case of communication between objects as in the present embodiment, there is a feature that the main information traffic is small and the ratio of control information traffic is relatively large as compared with communication between people. Utilizing this feature, frame utilization efficiency can be improved by optimizing the band allocation unit in the wireless MAC (Media Access Control) layer. The above are features that are not found in conventional mobile phone networks and PHS networks. However, if a large number of small wireless communication terminals 100 can be accommodated, the wireless network with which the transmission / reception means 103 communicates may be a mobile phone network or a PHS network.

  In the information terminal 200 shown in FIG. 2, the control means 201 is composed of a CPU or the like, and controls each means in the information terminal 200. The storage unit 202 is an SRAM or SDRAM for temporarily holding information while the power of the information terminal 200 is ON, or for holding information for a long time while the power of the information terminal 200 is OFF. , ROM, EEPROM, flash memory, etc., and stores various information. The transmission / reception unit 203 includes an antenna, a transmission / reception circuit, and the like, and communicates with the outside by wireless communication such as a PDC-P method.

  The infrared data communication means 204, which is a narrow area communication means, is composed of a light emitting element or a light receiving element for infrared communication, and performs infrared communication by the IrDA method with the small wireless communication terminal 100. The display unit 205 is configured by a liquid crystal display, an organic EL display, or the like, and displays various types of information in a format (characters, symbols, graphics, etc.) that allows a person to identify the contents of information. In FIG. 2, it is assumed that illustrations of power supply means, operation means, and the like, which are other configurations of the information terminal 200, are omitted.

  Next, the operation when the small wireless communication terminal 100 and the information terminal 200 according to the present embodiment perform communication will be described. When information is transmitted from the small-sized wireless communication terminal 100 to the information terminal 200 and the information is displayed by the display unit 205 of the information terminal 200, the following is performed. The storage means 102 of the small wireless communication terminal 100 contains information stored in advance at the time of product shipment, or information received from the outside by the transmission / reception means 103 and stored by the control means 101. The control unit 101 reads the information from the storage unit 102 and outputs it to the infrared data communication unit 104. The infrared data communication means 104 transmits information to the information terminal 200 placed in the vicinity of the small wireless communication terminal 100 by infrared communication.

  The infrared data communication unit 204 of the information terminal 200 receives the information and outputs it to the control unit 201. After the information is stored in the storage unit 202, the control unit 201 reads the information from the storage unit 202 at a timing to display the information, performs processing such as converting the format of the information to be suitable for display, and then stores the information. Output to the display means 205. The display means 205 displays the information. As a result, the user can check the information stored in the small wireless communication terminal 100.

  In addition, when information displayed by the display unit 205 of the information terminal 200 is transmitted from the information terminal 200 to the small wireless communication terminal 100, the following is performed. The transmission / reception means 203 of the information terminal 200 receives information from outside and outputs it to the control means 201. After the information is stored in the storage unit 202, the control unit 201 reads the information from the storage unit 202 at a timing to display the information, performs processing such as converting the format of the information to be suitable for display, and then stores the information. Output to the display means 205. The display means 205 displays the information. Thereby, the user can confirm the information transmitted to the small wireless communication terminal 100. This information is appropriately changed by the user.

  Subsequently, the control unit 201 reads the information from the storage unit 202 and outputs it to the infrared data communication unit 204. The infrared data communication unit 204 transmits information to the small wireless communication terminal 100 by infrared communication. The infrared data communication means 104 of the small wireless communication terminal 100 receives information and outputs it to the control means 101. The control unit 101 stores information in the storage unit 102. When this information is further transferred to the outside, the information is read from the storage means 102 by the control means 101 and transmitted by the transmission / reception means 103.

  In the present embodiment, a mobile phone terminal is assumed as the information terminal 200. Many mobile phone terminals are equipped with IrDA narrow-area communication means, so that data communication can be performed between them and the infrared data communication means 104 of the small wireless communication terminal 100. Thereby, the information received by the transmission / reception means 103 which is the main communication means of the small wireless communication terminal 100 can be transferred to the information terminal 200 and the contents thereof can be displayed on the display means 205 of the information terminal 200.

  For example, a key such as a house is provided with a communication function (implemented by incorporating the small wireless communication terminal 100 according to the present embodiment into a handle portion or the like) and communicates with a lock that is paired with the lock, thereby There is a system for remotely monitoring the state (Japanese Patent Application No. 2004-339397). This is a system that prevents a malicious third party from snooping by allowing only the owner to remotely monitor the lock. If only the lock state is present, it is sufficient to represent the two states of opening and closing, and the display means may be an LED or the like. In this case, the display means can be built in a small space such as a key handle.

  However, if it is desired to display various types of home security information (such as gas main plug status, glass window lock status, etc.) as an advanced form of the system, it is difficult to deal with LED or the like. Although it is desirable to employ a liquid crystal display or the like capable of displaying text information as the display means, it is difficult to implement such a display means as a key pattern. In such a case, the small wireless communication terminal 100 of the present embodiment that has acquired the home security information from an external device such as various devices transfers the home security information to the information terminal 200 such as a mobile phone, and the display means such as a liquid crystal display. By displaying the above, it is possible to solve the problem.

  Conversely, text data created by the information terminal 200 can be transmitted to the small wireless communication terminal 100 and transmitted to the outside via the transmission / reception means 103 of the small wireless communication terminal 100. This text data is data used for the various applications described above. For example, since the transmission / reception means 103 which is the main communication means is used for communication between objects, the transmission / reception means 103 may be in a narrow area. It may be too big. In such a case, the information terminal 200 downloads (receives) the calibration data via the mobile phone network, and transfers it to the small wireless communication terminal 100 by the infrared data communication means 204 as the narrow area communication means. Cost can be reduced.

  As described above, the cellular phone terminal is assumed as the information terminal 200 because the small wireless communication terminal 100 is often embedded in various objects, particularly mobile objects, and the information terminal 200 as a display means is also portable. This is because it is often more convenient to use a mold. According to the same idea, there is no problem even if the information terminal 200 is a portable information terminal such as a PDA (Personal Digital Assistance). Further, when the small wireless communication terminal 100 can be freely carried by the user's intention, the information terminal 200 may be a stationary information terminal such as a PC (Personal Computer).

  In this embodiment, the infrared data communication means is provided in the small wireless communication terminal and the information terminal as the narrow area communication means, but the narrow area communication means is not limited to this. For example, an electromagnetic induction method used for communication between a passive tag that does not have a power source and a reader, Bluetooth (registered trademark), or the like can be considered as the narrow area communication unit. On the other hand, the most popular portable information terminal such as a mobile phone terminal or PDA is the IrDA system for infrared data communication. Therefore, in consideration of user convenience, it is desirable that the narrow area communication means be an infrared data communication means based on the IrDA method.

  As described above, in this embodiment, information communication is performed between a small wireless communication terminal for which it is difficult to secure a display space and an information terminal having a display unit, and information handled by the small wireless communication terminal is displayed on the information terminal. Is done. As a result, information handled by the small wireless communication terminal can be easily displayed on an information terminal different from the small wireless communication terminal.

  Next, a second embodiment of the present invention will be described. FIG. 4 shows the configuration of the small wireless communication terminal 300, and FIG. 5 shows the configuration of the information terminal 400. Similarly to the first embodiment, the small wireless communication terminal 300 is also the above-described wireless tag (IC tag, small wireless IC tag) or the like, and a format (characters or symbols, It does not have a means for displaying the information in a figure or the like. The information terminal 400 is also a mobile phone terminal in this embodiment. FIG. 6 shows a state where the small wireless communication terminal 300 and the information terminal 400 communicate. Thus, communication between both terminals is performed in a state where the small wireless communication terminal 300 and the information terminal 400 are arranged close to each other. This communication is performed when the information terminal 400 optically reads the two-dimensional code displayed by the small wireless communication terminal 300.

  In the small wireless communication terminal 300 shown in FIG. 4, the control means 301, the storage means 302, the transmission / reception means 303, and the power supply means 305 are respectively the control means 101 and the storage provided in the small wireless communication terminal 100 according to the first embodiment. The same as the means 102, the transmission / reception means 103, and the power supply means 105. The difference from the first embodiment is not to transmit data by modulating electromagnetic waves as a carrier (hereinafter, this method is referred to as a radio wave system) as in the infrared data communication means 104 of FIG. A two-dimensional code display means 304 for realizing a method for transferring data is provided. The two-dimensional code display means 304 is constituted by a liquid crystal display, an organic EL display, or the like, and displays a two-dimensional code based on information possessed by the small wireless communication terminal 300. In this embodiment, the information transfer direction is one direction from the small wireless communication terminal 300 to the information terminal 400.

  In the information terminal 400 shown in FIG. 5, the control means 401, the storage means 402, the transmission / reception means 403, and the display means 405 are respectively the control means 201, the storage means 202, and the transmission / reception means included in the information terminal 200 according to the first embodiment. 203 and the display unit 205. The difference from the first embodiment is that there is provided an image pickup means 404 that realizes a method of optically transferring data, instead of transferring data by a radio wave method, like the infrared data communication means 204 of FIG. It is a point.

  The image capturing unit 404 optically reads a two-dimensional code, and therefore an image sensor that converts an optical image into an electric signal by photoelectric conversion, or a two-dimensional code displayed by the two-dimensional code display unit 304 of the small wireless communication terminal 300. Is formed of a camera having an optical lens that forms an image on the imaging surface of the image sensor. The imaging unit 404 captures a two-dimensional code and generates image data. In FIG. 5, it is assumed that illustrations of power supply means, operation means, and the like, which are other configurations of the information terminal 400, are omitted.

  Next, an operation when the small wireless communication terminal 300 and the information terminal 400 perform communication according to the present embodiment will be described. The storage unit 302 of the small wireless communication terminal 300 includes information stored in advance at the time of product shipment, or information received from the outside by the transmission / reception unit 303 and stored by the control unit 301. The control unit 301 reads the information from the storage unit 302, generates a two-dimensional code based on the information, and outputs the two-dimensional code to the two-dimensional code display unit 304. The two-dimensional code display unit 304 displays a two-dimensional code.

  The imaging unit 404 of the information terminal 200 placed in the vicinity of the small wireless communication terminal 300 captures a two-dimensional code, generates image data, and outputs it to the control unit 401. The control unit 401 restores the two-dimensional code based on the image data, and decodes the two-dimensional code to restore the original information. After storing the information in the storage unit 402, the control unit 401 reads the information from the storage unit 402 at a timing to display the information, and performs processing such as converting the format of the information to be suitable for display. Is output to the display means 405. Display means 405 displays the information. As a result, the user can check the information stored in the small wireless communication terminal 300.

  As a two-dimensional code that can be restored by a mobile phone terminal with a camera such as the information terminal 400, a QR code is generally used. In the case of a QR code, it is possible to display 25 alphanumeric characters in 21 cells × 21 cells. Considering that the cell size identifiable by a camera of a general mobile phone terminal is 0.28 mm, the space necessary for displaying the QR code is about 6 mm × 6 mm. When 25 alphanumeric characters are displayed in this area, it can be said that the amount of information per predetermined area is larger than when alphanumeric characters are directly displayed on the display under conditions that can be read by human eyes.

  In this embodiment, a camera-equipped mobile phone is assumed as the information terminal 400. However, if a camera for photographing a QR code and software for decoding the obtained QR code are installed, information such as a PDA can be obtained. It can also be used as the terminal 400. Further, as described in the first embodiment, when the small wireless communication terminal 300 can move freely, the information terminal 400 is a stationary information terminal such as a PC to which a camera is connected. There may be.

  In the first embodiment, in a radio wave system such as infrared data communication, Bluetooth (registered trademark), or passive tag system adopted as a communication system between a small wireless communication terminal and an information terminal, a malicious third party can remotely There is a risk of so-called skimming, in which information is stolen by transmitting a read signal from. On the other hand, in the method in which the information terminal optically reads the two-dimensional code displayed by the small wireless communication terminal as in this embodiment, the pattern is recognized in the immediate vicinity of the displayed two-dimensional code, that is, a QR code. It is difficult to obtain information unless the camera of the information terminal is brought as close as possible.

  In addition, it is difficult to obtain information even when a small wireless communication terminal is placed in a bag or the like and cannot be seen with the naked eye. That is, in the case of a method for optically transferring information, compared to the radio wave method, two conditions are added that the displayed two-dimensional code can be seen and that the displayed two-dimensional code is sufficiently close. The risk of skimming can be greatly reduced.

  As described above, the embodiments of the present invention have been described in detail with reference to the drawings. However, the specific configuration is not limited to these embodiments, and includes design changes and the like without departing from the gist of the present invention. .
