Description

  The present invention relates to an RFID system that switches between reception of a passive RFID tag and transmission / reception of an active RFID tag and acquires detailed information based on the received tag data.

  In recent years, a management system using a wireless IC tag has been proposed for the purpose of improving the efficiency of article management (Non-Patent Document 1). In this document, an RFID tag is attached to an article such as an office machine such as a PC used in an office, and an RFID reader is brought close to the tag to read data stored in the tag. Then, the presence of the article can be confirmed by matching the received data with the data in the inventory ledger. In such operations, passive RFID tags that do not have their own power supply are often used. A passive tag operates by receiving radio waves emitted from an RFID reader or the like, and transmits data stored in a storage unit inside the tag to the RFID reader.

  On the other hand, there is also a type called an active tag that is equipped with a power supply and transmits or receives data stored in the storage unit inside the tag. In this active tag system, the data transmission side may be called a master unit and the data reception side may be called a slave unit. As an example of a system using this active type tag, there is one used for managing the number of boxes for transport and position management in a collection and delivery center (Patent Document 1).

  Passive tags have a reading distance of several centimeters to several tens of centimeters, whereas active tags can be sent and received even at a distance of several tens of meters. It is customary.

The control unit 302 has a function of acquiring related data from a storage unit 303 (to be described later) based on the ID data received by the communication unit 301 when there is an ID data inquiry request from the portable information terminal 1. .
The storage unit 303 is a memory or a hard disk that stores ID data and detailed information related thereto. The detailed information may be given general information such as a product with a tag attached thereto, or a type of R / W setting information for performing R / W setting. Further, the detailed information may include information indicating whether or not the execution mode of the portable information terminal 1 can be switched.

  FIG. 4 is a sequence diagram of ID data transmission / reception processing. This sequence diagram is described based on UML (Unified Modeling Language) notation. First, the control unit 101 of the portable information terminal 1 acquires an execution mode related to the reading process from the storage unit 102 (S400). If the next execution mode is the passive mode, the process proceeds to S401. If the next execution mode is the active type, the process proceeds to S403. If the next execution mode is the active type, the process proceeds to S405.

  The control unit 101 reads out the passive mode execution command group stored in the storage unit 102, and controls the R / W device unit using these execution commands (S401). The R / W device unit 103 that has received the command emits radio waves to the RFID tag and waits for a reaction from the RFID tag (S402). If the ID data is correctly received from the RFID tag, the process proceeds to S407, and if the ID cannot be received, the process proceeds to S411.

  Subsequently, after waiting for the switching waiting time acquired from the storage unit 102, the execution timing adjusting unit 113 notifies the execution mode switching unit 110 for switching the execution mode. The execution mode switching unit 110 that has received the notification switches the execution mode to the R / W device unit 103 via the control unit 101.

  On the other hand, similarly in the active type slave unit mode, the control unit 101 reads the execution command group of the active type slave unit mode stored in the storage unit 102 and uses these execution commands to read the R / W device unit. Is controlled (S403). The R / W device unit 103 that has received the command performs carrier sense processing in order to detect radio waves emitted from the active master unit (S404). Since no radio waves are emitted from the active slave unit, the carrier sense process may be omitted. When the radio wave transmitted by the active RFID tag is detected and the ID data from the active RFID tag is correctly received, the process proceeds to S407. If the ID data cannot be received correctly, the process proceeds to S411.

  In the active master mode, the control unit 101 reads the active command mode execution command group stored in the storage unit 102, and controls the R / W device unit using these execution commands. (S405). The R./W device unit 103 that has received the command performs carrier sense processing to check whether the frequency band of the emitted radio wave is already in use, and emits the radio wave if it is available (S406).

  When the R / W device unit 103 can correctly receive the ID data from the passive tag or from the active master unit (S407), the received ID data is stored in the storage unit 102 and received by the control unit 101. A notification of success is sent (S408). Based on the stored ID data, the control unit 101 uses the communication unit 104 to query the server 3 for ID data (S409). At this time, the user may be notified of ID reception using the display unit 105 and the output unit 106.

  When the communication unit 301 of the server 3 receives the ID data inquiry from the communication unit 104 of the portable information terminal 1, the control unit 302 reads detailed information related to the received ID data from the data stored in the storage unit 303. The execution mode switchability information is extracted and returned as detailed information using the communication unit 301 (S410). When receiving the detailed information, the communication unit 104 of the portable information terminal 1 presents the detailed information to the user using the display unit 105 and the output unit 106.

  On the other hand, when the ID data from the passive tag or from the active master cannot be correctly received, the R / W device unit 103 returns a reception timeout error to the control unit 101 (S411). The control unit 101 does not have to present this error to the user using the display unit 105 or the output unit 106.

Subsequently, when there is a switch to a different execution mode, the execution timing adjustment unit 113 waits for the switching waiting time acquired from the storage unit 102 (S412), and switches the execution mode to the execution mode switching unit 110. For notification. Upon receiving the notification, the execution mode switching unit 110 switches the execution mode to the R / W device unit 103 via the control unit 101 (S413).
After performing the above processing, the process returns to the first (S400) to perform continuous execution.

FIG. 5 is a process flow diagram in the passive tag ID reception mode.
First, the process of the passive tag ID reception mode is started from S500 (S500). First, it is determined whether the communication duration / number of executions stored in the storage unit 102 has expired (S501). If the communication duration / number of executions has expired, the process proceeds to S503. If it has not expired, it indicates that the reading time / number of times remains, and the process proceeds to S502.

If the communication duration // the number of executions remains, the passive tag reading process is performed and the process returns to S501 (S502). This process corresponds to S401 in the sequence diagram of FIG. Here, when the tag reading process is successful, the communication duration / number of executions may be updated to zero. As a result, when the reception is successful once, it is possible to proceed immediately to the steps after S504.
On the other hand, if the communication duration / number of executions has expired, it is determined whether or not the ID data reading process has succeeded (S503). If the reading is successful, the process proceeds to S504. If the reading is unsuccessful, the process proceeds to S511.

If the reading is successful, the output unit 106 and the display unit 105 are controlled to notify the user that the ID has been successfully received (S504). For example, notification is performed by a display panel, LED, voice, and vibration function. Then, it progresses to S505.
In the reception tag selection process, the ID filter unit 114 determines whether the ID data has already been received (S505). If there is an overlap, it is discarded, and if there is no overlap, it is stored in the storage unit 102, and the process proceeds to S506.

When an ID inquiry request is received from the user via the input unit 107, the process proceeds to S507 (S506). If no request has been received, the process returns to S506 as a request waiting state. However, if the setting is such that the server inquiry is automatically made after receiving the ID, the process of S506 is omitted and the process proceeds to S507.
In the ID inquiry processing to the server (S507), the ID inquiry means 111 instructs to read out the connection destination information (for example, URL) of the server 3 and the ID data to be inquired stored in the storage unit 102 in the control unit 101. After that, the communication unit 104 is instructed to make an inquiry to the server 3, and the process proceeds to S508.

The detailed information receiving unit 112 stores the detailed information returned from the communication unit 301 of the server 3 in the storage unit 102, and then determines the type of the detailed information (S508). If the detailed information is R / W setting information, the process proceeds to S510, and if the detailed information is general information, the process proceeds to S509.
When the type of the detailed information is general information (S509), the control unit 101 instructs the display of the detailed information using the display unit 105, and the process proceeds to S511.

On the other hand, when the type of the detailed information is R / W setting information (S510), the R / W device setting unit 116 determines the R / W device unit according to the detailed information regarding the next execution mode stored in the storage unit 102. The setting is reflected to 103, and the process proceeds to S511. For example, the frequency channel of the radio wave used for transmission / reception, the gain value, the number of reading or transmission, the execution time, etc. are set.
In the switchability acquisition process, information about switchability included in the received detailed information is acquired (S511). If information that allows switching to the active master mode or slave mode is included, the process proceeds to S512. If switching is impossible, the process returns to S501 and the passive reception process is continued. Note that if the received detailed information does not include information on whether or not switching is possible, the process may automatically proceed to S512.

In the switching waiting process (S512), the execution timing adjusting unit 113 waits until the switching waiting time stored in the storage unit 102 elapses, and proceeds to S513. At this time, the measurement start timing of the switching waiting time may be the time of the tag reading process, or may be the timing when the server inquiry or the detailed information reception is completed.
Finally, after the processing in the passive tag ID reception mode is completed, the execution mode switching unit 110 instructs the control unit 101 to switch to the active master mode or the active slave mode (S513). After performing initialization processing such as communication settings in each execution mode, the process proceeds to S600 when shifting to the active slave mode, and to S700 when shifting to the active master mode.

FIG. 6 is a process flow diagram in the active slave mode.
First, the processing of the active slave mode is started from S600 (S600). First, it is determined whether the communication duration / number of executions stored in the storage unit 102 has expired (S601). If the communication duration / number of executions has expired, the process proceeds to S606. If it has not expired, it indicates that the reading time / number of times remains, and thus the process proceeds to S602.

Here, it is determined whether or not the communication duration for success has expired (S602). If it has expired, the process proceeds to S606, and if it has not expired, the process proceeds to S603.
If both the communication duration at the time of success and the communication duration / number of executions remain, the active RFID tag is read and the process proceeds to S604 (S603). This process corresponds to S403 in the sequence diagram of FIG. Here, when the tag reading process is successful, the communication continuation time upon success and the communication continuation time / number of executions may be updated to zero. As a result, when the reception is successful once, it is possible to proceed immediately to the steps after S606.

On the other hand, if the communication continuation time / execution count has expired, it is determined whether or not the ID data reading process of the active RFID tag has succeeded (S606). If the reading is successful, the process proceeds to S607. If the reading is unsuccessful, the process proceeds to S614.
If the reading is successful, the output unit 106 and the display unit 105 are controlled to notify the user that the ID has been successfully received (S607). For example, notification is performed by a display panel, LED, voice, and vibration function. Thereafter, the process proceeds to S608.

In the reception tag selection process, the ID filter unit 114 determines whether there is duplication with already received ID data. If there is duplication, it is discarded, and if there is no duplication, it is stored in the storage unit 102, and the process goes to S609. Proceed (S608). Here, when a plurality of ID data are received, a process of acquiring ID data having the strongest signal strength may be performed.
If an ID inquiry request is received from the user via the input unit 107, the process proceeds to S610 (S609). If no request has been received, the process returns to S609 as a request waiting state. However, if the server inquiry is automatically set after receiving the ID, the process of S609 is omitted and the process proceeds to S610.

In the ID inquiry processing to the server (S610), the ID inquiry means 111 instructs the controller 101 to read the connection destination information (for example, URL) of the server 3 and the ID data to be inquired, which are stored in the storage unit 102. After that, the communication unit 104 is instructed to make an inquiry to the server 3, and the process proceeds to S611.
The detailed information receiving unit 112 stores the detailed information returned from the communication unit 301 of the server 3 in the storage unit 102, and then determines the type of the detailed information (S611). If the detailed information is R / W setting information, the process proceeds to S613. If the detailed information is general information, the process proceeds to S612.

When the type of the detailed information is general information (S612), the control unit 101 instructs the display of the detailed information using the display unit 105, and the process proceeds to S614.
On the other hand, when the type of the detailed information is R / W setting information (S613), the R / W device setting unit 116 determines the R / W device unit according to the detailed information regarding the next execution mode stored in the storage unit 102. The setting is reflected to 103, and the process proceeds to S614. For example, as described above, the frequency channel and gain value of radio waves used for transmission and reception, the number of reading or transmission, the execution time, and the like are set.

  In the switchability acquisition process, information about switchability included in the received detailed information is acquired (S614). If information that allows switching to the passive tag ID reception mode or the active master mode is included, the process proceeds to S615. If switching is not possible, the process returns to S601 and the reception process by the active slave unit is continued. If the received detailed information does not include information on whether or not switching is possible, the process may automatically proceed to S614.

In the switching waiting process (S615), the execution timing adjusting unit 113 waits until the switching waiting time stored in the storage unit 102 elapses, and proceeds to S616. At this time, the measurement start timing of the switching waiting time may be the time of the tag reading process, or may be the timing when the server inquiry or the detailed information reception is completed.
Finally, after the processing in the active slave mode is completed, the execution mode switching unit 110 instructs the control unit 101 to switch to the passive tag ID reception mode or the active master mode (S616). After performing initialization processing such as communication settings in each execution mode, the process proceeds to S500 when shifting to the passive tag ID reception mode, and to S700 when shifting to the active master mode.

FIG. 7 is a processing flow chart in the active master mode.
First, the processing of the active master mode is started from S700 (S700). First, it is determined whether the communication duration / number of executions stored in the storage unit 102 has expired (S701). If the communication duration / number of executions has expired, the process proceeds to S703. If it has not expired, it indicates that the transmission time remains, and the process proceeds to S702.

If the communication duration / number of executions remains, ID transmission processing is performed in the active master mode, and the process returns to S701. This ID transmission processing corresponds to S405 in the sequence diagram of FIG.
On the other hand, when the communication continuation time / number of executions has expired, the information regarding the switchability included in the detailed information received so far is acquired (S703). If information that allows switching to another execution mode is included, the process proceeds to S704. If switching is not possible, the process returns to S701 to continue the ID transmission process. If the detailed information received so far does not include information regarding whether or not switching is possible, the process may automatically proceed to S704.

In the switching waiting process (S704), the execution timing adjusting unit 113 waits until the switching waiting time stored in the storage unit 102 elapses, and proceeds to S705. At this time, the measurement start timing of the switching waiting time is set to the timing at which ID data starts to be transmitted with the current setting.
Finally, the execution mode switching unit 110 instructs the control unit 101 to switch to a different execution mode such as the passive mode or the active slave mode after the processing in the active master mode is completed (S705). After performing initialization processing such as communication settings in each execution mode, the process proceeds to S500 when shifting to the passive tag ID reception mode, and to S600 when shifting to the active slave mode.
As described above, the content of the ID data reception result in the active master mode, passive tag ID reception mode or active slave mode, or automatically switches to a different execution mode when the number of executions or execution time expires Various services can be realized.

A second embodiment according to the present invention will be described below with reference to FIGS.
Since the configuration example of the server shown in FIG.
Prior to the description of the difference between the processing sequences of FIGS. 4 to 7, the difference in the configuration related to the second embodiment will be described with reference to FIG.

FIG. 8 is a configuration example of a portable information terminal according to the second embodiment of the present invention. It is assumed that the physical size of the portable information terminal of the second embodiment is smaller than that of the first embodiment.
That is, since the RFID R / W function is realized with only a minimum configuration, the portable information terminal 1 does not include the input unit 107 in the configuration of the second embodiment. Therefore, the R / W control command group received via the communication unit 104 is temporarily stored in the storage unit 102, and the control unit 101 executes the R / W control command group to control the R / W device unit 104. .

Similarly, the portable information terminal 1 is not necessarily provided with the output unit 106 and the display unit 105. However, if the portable information terminal 1 is not provided, the output processing and display processing after S408 and S410 cannot be performed. On the other hand, when outputting the execution result of the above R / W control command group, the current or next execution mode, or an error state to the outside, it is preferable to provide an output unit 106 composed of, for example, LEDs. Further, the execution result may be transmitted using the communication unit 104.
Finally, FIG. 4 to FIG. 7 show a processing sequence related to the second embodiment of the present invention, but the same parts as those of the first embodiment are omitted and only the differences are shown.

For the ID data transmission / reception processing shown in FIG. 4, the portable information terminal 1 is not necessarily provided with the ID inquiry means 111 and the detailed information receiving means 112, but if these are provided, the communication unit 104 is used. Communication with the communication unit 301 of the server 3 is possible.
The processing sequences related to the execution modes shown in FIGS. 5 to 7 are the same operation, and thus the description thereof is omitted.
