Description

  The present invention relates to a portable information terminal, and more particularly to a portable information terminal that communicates with both a passive RFID tag and an active RFID tag.

  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 the management system, 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 (hereinafter also referred to as a portable information terminal) is brought close to the tag so that the RF reader Reads the data stored in the tag. Then, the user can confirm the presence of the article by matching the read received data with the data in the inventory book. In such operations, passive RFID tags that do not have their own power supply are often used. The passive tag operates by generating power from 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 data stored in a storage unit inside the tag or receives data from the outside. As an example of a system using this active type tag, there is one used for managing the number of boxes for transport and the location 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.

FIG. 3 is a configuration example of the server 3. As illustrated in FIG. 3, the server 3 includes a communication unit 301, a control unit 302, and a storage unit 303.
The communication unit 301 is a communication module for performing data transmission / reception with the communication unit 104 of the portable information terminal 2. It has a function of receiving an inquiry about ID data from the portable information terminal 2 and returning detailed information related to the ID data. If there is no information related to the storage unit 303 of the server 3, it may have a function of redirecting communication and connecting to another server.

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 2. .
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 2 can be switched.

  FIG. 4 is a sequence diagram of the ID data reading process. This sequence diagram is described based on UML (Unified Modeling Language) notation. First, the control unit 101 of the portable information terminal 2 acquires an execution mode related to the next reading process (S400). When the execution mode is the passive mode, the process proceeds to S401, and when the execution mode is the active mode, the process proceeds to S403.

  When the execution mode is the passive mode, the control unit 101 reads the passive mode execution command group stored in the storage unit 102 and transmits it to the R / W device unit 103 according to the command (S401). The R / W device unit 103 that has received the command emits radio waves to the RFID tag 2 and waits for a reaction from the RFID tag 2 (S402). If the ID data can be correctly received from the RFID tag 2 here, the process proceeds to S405, and if the ID cannot be received, the process proceeds to S409.

  Subsequently, the execution timing adjustment unit 113 waits for the switching waiting time acquired from the storage unit 102 and then notifies the execution mode switching unit 110 to switch the execution mode to the active mode. Upon receiving the notification, the execution mode switching unit 110 causes the R / W device unit 103 to switch the execution mode via the control unit 101.

  On the other hand, when the execution mode is the active mode, similarly, the control unit 101 reads out the active mode execution command group stored in the storage unit 102 and transmits it to the R / W device unit 103 according to the command (S403). ). The R / W device unit 103 that has received the command performs carrier sense processing in order to detect the radio wave emitted from the RFID tag 2 (S404). If the radio wave from the RFID tag 2 is detected and the ID data is correctly received, the process proceeds to S405. If the ID data cannot be received correctly, the process proceeds to S409.

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 to the passive mode. Upon receiving the notification, the execution mode switching unit 110 causes the R / W device unit 103 to switch the execution mode via the control unit 101.
When the R / W device unit 103 has received the ID data of the RFID tag 2 correctly, the R / W device unit 103 stores the received ID data in the storage unit 102 and notifies the control unit 101 of successful reception (S406). Based on the stored ID data, the control unit 101 uses the communication unit 104 to query the server 3 for ID data (S407). 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 (S408). 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, if the ID data cannot be correctly received in the previous S405, the R / W device unit 103 returns a reception timeout error to the control unit 101 (S409). The control unit 101 does not have to present this error to the user using the display unit 105 or the output unit 106.
After performing the above processing, the process returns to the first (S400) to perform continuous execution.

  As described above, according to the sequence diagram of FIG. 4, the portable information terminal 1 communicates information with the RFID tag 2 regardless of whether the RFID tag 2 is a passive type or an active type. Can do. This eliminates the need to prepare separate portable information terminals for each of the passive type and the active type. Furthermore, since switching between the passive type and active type execution modes can be performed automatically as described above, it is not necessary for the user to know the type of the RFID tag and switch the execution mode consciously. For this reason, the usability of the portable information terminal for the user can be improved. It should be noted that it is not essential that the execution mode is switched automatically, and the case where the user manually sets the mode is also included in the present embodiment, but the following description is mainly directed to the case where it is automatic.

FIG. 5 is a process flow diagram in the passive execution mode.
First, the processing in the passive execution mode starts from S500 (S500). First, the control unit 101 determines whether the communication continuation time stored in the storage unit 102 has expired (S501). If the communication duration has expired (Yes), the process proceeds to S503. If it has not expired (No), it indicates that the reading time remains, and the process proceeds to S502.

If the communication duration 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 time 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 continuation time has expired, it is determined whether the ID data reading process has succeeded (S503). If the reading is successful (Yes), the process proceeds to S504. If the reading is unsuccessful (No), the process proceeds to S512.

If the reading is successful, the control unit 101 controls the output unit 106 and the display unit 105 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.

If an ID inquiry request is received from the user via the input unit 107 (Yes), the process proceeds to S507 (S506). If no request has been received (No), 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 reads 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 the instruction, 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 reflects the setting in the R / W device unit 103 according to the detailed information, and the process proceeds to S511. For example, the frequency channel and gain value of the emitted radio wave, the number of executions during reading, and the like are set.

  In the switchability acquisition process, the control unit 101 acquires information regarding the switchability included in the received detailed information (S511). If information that allows switching to active is included (Yes), the process proceeds to S512. If switching is not possible (No), the process returns to S501 to continue the passive reception process. 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. In addition, the switching waiting time may be extended longer when the ID data reading process in S503 is successful than when it is not successful. Thereby, when it is not successful, switching to another execution mode can be accelerated.
Finally, after the processing in the passive execution mode is completed, the execution mode switching unit 110 instructs the control unit 101 to switch to the active execution mode (S513). After initialization processing such as communication in the active execution mode, the process proceeds to S600 in FIG.

FIG. 6 is a process flow diagram in the active execution mode.
First, the processing in the active execution mode starts from S600 (S600). First, the control unit 101 determines whether the communication duration time stored in the storage unit 102 has expired (S601). If the communication duration has expired (Yes), the process proceeds to S606. If it has not expired (No), it indicates that the reading time remains, and the process proceeds to S602.

Here, the control unit 101 determines whether the successful communication duration has expired (S602). If it has expired (Yes), the process proceeds to S606, and if it has not expired (No), the process proceeds to S603. The successful communication duration may be longer than the communication duration in S601. Thus, when the ID data reading process in S604 is not successful, the switching to another execution mode can be accelerated.
If both the communication duration at the time of success and the communication duration remain, the control unit 101 performs an active tag reading process and proceeds to S604 (S603). This process corresponds to S403 in the sequence diagram of FIG. If the tag reading process is successful in S604 (Yes), the control unit 101 starts measuring the communication duration when successful (S605) and returns to S602, but sets the communication duration and communication duration when successful. You may update to 0. 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 has expired, the control unit 101 determines whether the ID data reading process has succeeded (S606). If the reading is successful (Yes), the process proceeds to S607, and if the reading is unsuccessful (No), the process proceeds to S615.
If the reading is successful, the control unit 101 controls the output unit 106 and the display unit 105 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 (Yes), the process proceeds to S610 (S609). If no request has been received (No), the flow 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 reflects the setting in the R / W device unit 103 according to the detailed information, and the process proceeds to S614. For example, as described above, the frequency channel and gain value of the emitted radio wave, the number of executions at the time of reading, and the like are set.
In the switchability acquisition process, the control unit 101 acquires information regarding the switchability included in the received detailed information (S614). If information that allows switching to passive is included, the process proceeds to S615. If switching is impossible, the process returns to S601 and the active 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 S615.

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. Further, the switching waiting time may be extended longer when the ID data reading process at S604 is successful than when it is not successful. Thereby, when it is not successful, switching to another execution mode can be accelerated.
Finally, after the processing in the active execution mode is completed, the execution mode switching means 110 instructs the control unit 101 to switch to the passive execution mode (S616). After initialization processing such as communication in the passive execution mode, the process proceeds to S500.
As described above, regardless of whether the ID data is successfully received in both the passive execution mode and the active execution mode, the user automatically switches to a different execution mode, so that the user can recognize the ID without being aware of the current execution mode. Various services obtained as a result of reading data can be enjoyed.

Hereinafter, only a difference between the second embodiment of the present invention and the first embodiment will be described with reference to FIGS.
First, FIG. 7 is a functional configuration example of the portable information terminal of the portable information terminal 1 according to the second embodiment of the present invention.

As shown in FIG. 7, the portable information terminal 1 further includes a sensor unit 108 and an operation detection unit 115 in addition to the configuration of FIG. 1 shown in the first embodiment.
The control unit 101 has a function of controlling the sensor unit 108 and the like according to requests in addition to the storage unit 102, the R / W device unit 103, the communication unit 104, the display unit 105, the output unit 106, and the input unit 107.
The sensor unit 108 is a sensor that measures displacement, speed, acceleration, and the like when the user carries the portable information terminal 2.

The operation detection unit 115 determines the user's operation based on the output of the sensor unit 108, and performs an operation in which the user approaches the portable information terminal 1 or the R / W device unit 103 toward the passive tag. A function of notifying the execution mode switching unit 110 and the control unit 101 when it is determined.
2 to 6 are the same in configuration and operation, and will be replaced by the description of the first embodiment.

  As described above, since the active tag has a long communication distance of several tens of meters with the portable information terminal 1, it is rare for the user to move the portable information terminal for communication. On the other hand, the passive tag is several tens of centimeters at the longest, and in order to communicate, the user often moves the portable information terminal near the RFID tag. In the second embodiment, paying attention to the difference in usage, when the sensor unit 108 detects displacement, speed, and acceleration, it is determined that the user wants to communicate with the passive tag, and the portable information terminal 1 execution mode is set.

FIG. 8 is an operation detection determination process flowchart according to the second embodiment of the present invention. This processing is executed in parallel with the processing in the passive execution mode and the active execution mode shown in FIG. 5 and FIG.
First, the operation detection unit 115 determines the user's operation based on the output of the sensor unit 108, and performs an operation in which the user approaches the portable information terminal 1 or the R / W device unit 103 toward the passive tag. If it is determined that it is (Yes), the process proceeds to S702 (S701). If no specific operation is performed (No), the process returns to S701. For example, it may be determined that a specific operation has been performed when an acceleration sensor or the like detects an operation of holding the portable information terminal 1 in hand and stopping it in front of the tag within a short period of time. Not exclusively.

  When the motion detection unit 115 detects a specific motion, when the control unit 101 is notified of this, the control unit 101 acquires the current execution mode (S702). If the current execution mode is the passive execution mode, the process proceeds to S704. On the other hand, if it is in the active execution mode, the process proceeds to S703, and the execution mode switching means 110 performs a process for switching to the passive execution mode (S703). This process is already defined in FIG. 5 as a flow from S500.

On the other hand, when the current execution mode is the passive execution mode, the control unit 101 is notified of this, and the control unit 101 temporarily extends the value of the current communication duration and stores the value in the storage unit 102. (S704).
In this way, the operation detection determination process is completed.

As described above, it is possible to improve the reading efficiency of the passive tag by performing the operation detection process of the user and extending the communication duration time or quickly switching from the active execution mode to the passive execution mode.
The embodiments of the present invention described so far are merely examples, and do not limit the present invention. For example, several modification examples can be considered in the block configuration diagrams of FIGS. 1 and 7 and the flowcharts of FIGS. 4 to 6 and FIG. 8, all of which fall within the scope of the present invention.
