  However, the above Patent Document 1 has a problem that it is difficult to realize automatic control depending on the environment on the infrastructure side.

  This is because it is necessary to install a transmission device on the infrastructure side, and the equipment cost for system construction increases. Also, it is not suitable for temporary system operation or system change. Furthermore, a transmitter cannot be installed in a place where power supply is difficult, and a system cannot be constructed.

  A portable terminal according to an aspect of the present invention includes a function unit that executes a predetermined function, a reading unit that reads information stored in the IC tag by wireless communication with an IC tag installed outside, And a control unit that stops the operation of the functional unit based on the information.

  In addition, the mobile terminal according to another aspect of the present invention provides information stored in the IC tag by wireless communication between a function unit that executes a predetermined function and an IC tag installed at an external fixed point. And a control unit that controls the operation of the functional unit based on the information.

  In addition, the IC tag according to one embodiment of the present invention stores information instructing to stop the operation of a predetermined function of the portable terminal so as to be readable by wireless communication with the portable terminal.

  An IC tag according to another aspect of the present invention is installed at a fixed point, and stores information for controlling operation of a predetermined function of the mobile terminal so as to be readable by wireless communication with the mobile terminal. To do.

  A control system according to one embodiment of the present invention includes an IC tag and a mobile terminal. In this control system, the IC tag stores information instructing operation stop of a predetermined function of the mobile terminal, and the mobile terminal reads the information by wireless communication with the IC tag, The operation of the function is stopped based on the information.

  A control system according to another embodiment of the present invention includes an IC tag installed at a fixed point and a mobile terminal. In this control system, the IC tag stores information for controlling the operation of a predetermined function of the portable terminal, and the portable terminal reads the information by wireless communication with the IC tag. The operation of the function is controlled based on the information.

  Further, the control program according to one embodiment of the present invention reads information stored in the IC tag by a process of executing a predetermined function on the mobile terminal and wireless communication with the IC tag installed outside. A process and a process of stopping the operation of the function are executed based on the information.

  Furthermore, a control program according to another aspect of the present invention is stored in the IC tag by a process for executing a predetermined function in the portable terminal and wireless communication with an IC tag installed at an external fixed point.

  That is, according to the present invention, it is only necessary to install an inexpensive IC tag on the infrastructure side when automatically controlling the mobile terminal, so that the equipment cost can be greatly reduced. In addition, since the IC tag is very small and can be easily installed, it can flexibly cope with temporary system operation and system change. Furthermore, when an IC tag that does not require power supply is used, restrictions on the installation location can be reduced.

  According to the present invention, it is possible to automatically control the operation of the mobile terminal without depending on the environment on the infrastructure side.

  DESCRIPTION OF EMBODIMENTS Hereinafter, embodiments of a control system according to the present invention and application examples (1) to (3) will be described with reference to FIGS. In the drawings, the same components are denoted by the same reference numerals, and redundant description is omitted as necessary for the sake of clarity.

[Embodiment]
A control system 100 according to the present embodiment shown in FIG. 1 includes an IC tag 10 installed on the infrastructure 6 side and a mobile terminal 20. The mobile terminal 20 includes a function unit 21 that executes a predetermined function, a reading unit 22 that reads information INF stored in the IC tag 10 through wireless communication with the IC tag 10, and a function unit 21 based on the information INF. And a control unit 23 for stopping the operation. In the illustrated example, when the operation of the functional unit 21 is stopped, the control unit 23 generates the control instruction INS. However, the control unit 23 may block the power supply to the functional unit 21.

  The IC tag 10 is preferably a passive RFID (Radio Frequency IDentification) tag. Here, the passive RFID tag is an IC tag that operates by converting a radio signal (radio wave) received from an information reading source (that is, the above-described reading unit 22) into electric power. No power supply is required.

  Further, as the IC tag 10, it is preferable to use an RFID tag using a 900 MHz band or a 2.4 GHz band capable of wireless communication of several meters among various passive RFID tags. In the 900 MHz band, since radio waves are easily diffracted (that is, not easily affected by obstacles), the entire range around the RFID tag can be set as a control target space for the portable terminal 20. On the other hand, in the 2.4 GHz band, since the straightness (directivity) of radio waves is high, only a specific range around the RFID tag can be set as a control target space. If it is desired to expand the control target space, a plurality of RFID tags storing the same information may be installed.

  In operation, as shown in FIG. 2, first, the reading unit 22 in the portable terminal 20 executes information reading processing from the IC tag 10, and gives the information INF obtained thereby to the control unit 23 (step S1). .

  FIG. 3 shows an example of information reading processing in the reading unit 22. However, the information reading process is not limited to the illustrated example, and may be executed in accordance with the wireless communication protocol adopted by the IC tag 10.

  First, the reading unit 22 sends out a wireless signal at a constant cycle (step S11). If the IC tag 10 exists within the reachable range of the radio signal, the IC tag 10 is activated by converting the radio signal into electric power, and sends its own ID information using the radio signal as a carrier frequency. To do.

  The reading unit 22 that has received the ID information recognizes the presence of the IC tag 10 (step S12), and transmits a command for instructing information transmission to the IC tag 10 (step S13). When a plurality of IC tags are installed on the infrastructure 6 side, the reading unit 22 can receive a plurality of ID information. In this case, for example, the reading unit 22 selects an IC tag installed closest to the mobile terminal 20 based on the reception strength (that is, radio wave strength) of each ID information, and transmits a command to the IC tag. .

  The reading unit 22 receives the information INF sent from the IC tag 10 in response to the above command (step S14).

  Returning to FIG. 2, the control unit 23 determines whether or not the information INF instructs to stop the operation of the functional unit 21 (step S2). When the information INF does not indicate that the operation is stopped, the control unit 23 performs no processing.

  On the other hand, when the information INF indicates the operation stop, the control unit 23 gives the function unit 21 a control instruction INS for instructing the operation stop, thereby stopping the operation of the function unit 21 (step S3). As described above, the control unit 23 may block power supply to the functional unit 21 instead of the control instruction INS.

  At this time, the control unit 23 waits for a predetermined time to elapse, for example, using a timer (step S4). When the predetermined time has elapsed, the control unit 23 causes the reading unit 22 to execute the information reading process shown in FIG. 3 again (step S5). As a result, if the same information INF is obtained (step S6), the control unit 23 determines that the mobile terminal 20 is still located in the control target space and returns to the above step S4. Maintain the operation stop state. In addition, when the user (not shown) who carries the portable terminal 20 moves frequently, it is suitable to set the time value of the timer short.

  On the other hand, when the same information INF is not obtained, the control unit 23 determines that the mobile terminal 20 is not located in the control target space, and gives a control instruction INS that instructs the function unit 21 to resume operation. Thus, the operation of the functional unit 21 is resumed (step S3). When the power supply to the function unit 21 is interrupted when the operation is stopped, the control unit 23 resumes the power supply to the function unit 21.

  Thus, in the control system 100, since only the IC tag 10 needs to be installed on the infrastructure 6 side, the equipment cost for constructing the system can be greatly reduced. Also, recent mobile terminals are equipped with resources such as highly functional arithmetic circuits. Therefore, by effectively using these existing resources, there is an advantage that the function of the control unit 23 can be easily added (that is, the amount of modification of the mobile terminal is small).

  Hereinafter, application examples (1) to (3) of the control system according to the present invention will be described with reference to FIGS.

[Application example (1)]
In the control system 100a shown in FIG. 4, the IC tag 10 is installed in the vicinity of the priority seat 61 in the vehicle 6a such as a train as an example of the infrastructure 6 shown in FIG. Moreover, the portable terminal 20 has the transmission function part 21a which transmits a radio signal at the time of communication with another communication apparatus as an example of the function part 21 shown in FIG. Further, in the information INF stored in the IC tag 10, 2-bit information “00” indicating “radio wave transmission prohibition” is set.

  In this case, the control unit 23 in the portable terminal 20 recognizes “radio wave transmission prohibition” from the information INF = “00” acquired by the reading unit 22, and stops the operation of the transmission function unit 21a. At the same time, the control unit 23 stops the operation of the reading unit 22. Thereby, the radio wave transmission from the mobile terminal 20 is stopped while the user is positioned near the priority seat 61.

  Thereafter, when a certain time has elapsed, the control unit 23 resumes the operation of the reading unit 22. Since the information INF cannot be obtained when the user gets off the vehicle 6a, the control unit 23 resumes the operation of the transmission function unit 21a. Thereby, it is possible to transmit radio waves from the mobile terminal 20, and thus the user can operate the mobile terminal 20 to perform desired communication.

[Application example (2)]
In the control system 100b shown in FIG. 5, the IC tag 10 is installed near the exhibit 62 in the museum 6b as an example of the infrastructure 6 shown in FIG. Further, the mobile terminal 20 includes a photographing function unit 21b that photographs an image or a moving image using the camera 24 as an example of the functional unit 21 illustrated in FIG. Further, the information INF stored in the IC tag 10 is set with 2-bit information “01” indicating “photographing prohibited”.

  In this case, the control unit 23 in the portable terminal 20 recognizes “shooting prohibited” from the information INF = “01” acquired by the reading unit 22 and stops the operation of the shooting function unit 21b. Thereby, it is possible to prevent the user from photographing the exhibit 62.

  Thereafter, when a predetermined time has elapsed and the user leaves the museum 6b and no information INF is obtained, the control unit 23 resumes the operation of the photographing function unit 21b. Thereby, the user can perform desired photographing outside the museum 6b.

[Application example (3)]
In the control system 100c shown in FIG. 6, the IC tag 10 is installed near the seat 63 in the movie theater 6c as an example of the infrastructure 6 shown in FIG. In addition, the mobile terminal 20 includes a ringing function unit 21c that rings a ring tone using the speaker 25 as an example of the function unit 21 illustrated in FIG. Further, the information INF stored in the IC tag 10 is set with 2-bit information “10” indicating “ringing prohibited”.

  In this case, the control unit 23 in the portable terminal 20 recognizes “ring prohibition” from the information INF = “10” acquired by the reading unit 22, and stops the operation of the ringing function unit 21c. Thereafter, when a certain time has elapsed and the user leaves the movie theater 6c and information INF is not obtained, the control unit 23 resumes the operation of the ring function unit 21c. As a result, ringing during the screening can be prevented.

  Note that the present invention is not limited to the above-described embodiments, and it is apparent that various modifications can be made by those skilled in the art based on the description of the scope of the claims.

  For example, in a control system, information for controlling the operation of a predetermined functional part of a mobile terminal (this information is an instruction to stop the operation) is placed on an IC tag installed at a fixed point (such as a wall of a building) May be stored). In this case, the mobile terminal controls the operation of the functional unit based on the information.

  Moreover, each process of the terminal device in this case, and each process of the terminal device shown in the above embodiment and application examples (1) to (3) can be provided as a program for causing a computer to execute. .
