In the figure, reference numeral 10 denotes a portable information terminal such as a PDA, a cellular phone, or a PHS (Personal Handy-phone System). . FIG. 2 is a block diagram showing a configuration example of a communication unit provided in the carried item confirmation system according to the present invention together with the portable information terminal of FIG. 1, in which 20 is a communication unit.

  The portable information terminal 10 is a CPU (Central Processing Unit) for controlling the entire apparatus, a ROM (Read Only Memory) for storing a control program having a registration mode and an operation mode, fixed data, and the like, and a working storage area for the CPU. The controller 11 includes a semiconductor memory such as a RAM (Random Access Memory). Here, the registration mode refers to a mode for registering a carried item or a processing method that is a target of the carried item confirmation process according to the present invention, and the operation mode refers to a mode for executing the carried item confirmation process.

  In addition to the control unit 11, the portable information terminal 10 stores a UID (Unique Identifier) of an RFID tag, a group number, an identifier number, and the like, a nonvolatile semiconductor memory such as a ferroelectric RAM, a hard disk device, and the like. Memory 12, key input unit 13 for inputting group number, identifier number, and operation mode (registration mode / operation mode), display unit 14 for displaying RFID tag UID, group number, and identifier number, warning about missing A speaker 15 that emits sound, a Bluetooth (registered trademark) antenna 16, a Bluetooth (registered trademark) communication unit 17, an RFID antenna 18, and a passive RFID tag reader unit 19 are configured.

  Note that the portable information terminal 10 is described as including the Bluetooth (registered trademark) antenna 16 and the wireless communication unit 17, but the present invention can be applied to other types of antennas and wireless communication units. In addition, the control unit 11 may be configured by a sub control unit that controls each unit such as the display unit 14 and the Bluetooth (registered trademark) communication unit 17 and a main control unit that controls the sub control unit. Further, FIG. 1 shows only a portion related to the present invention in the portable information terminal 10. As the constituent elements other than the above-described constituent elements, for example, when the portable information terminal 10 is a mobile phone, an antenna for performing a call, an RF radio unit, a microphone, and the like are usually used for imaging. Are mounted so as to be controllable by the control unit 11.

  The key input unit 13 accepts other user operations such as turning on / off the power supply and turning off the warning sound and warning display. The Bluetooth (registered trademark) communication unit 17 is configured to perform wireless communication in which a plurality of external communication units 20 installed at a place corresponding to the type of going out become a master (master communication device) and become a slave (slave communication device). Is possible. An example of the communication unit 20 and its installation location will be described later.

  The RFID tag reader unit 19 transmits radio signals to passive type RFID tags attached to a plurality of carry items, and receives response radio signals from the RFID tags to read the UID of the RFID tag. Hereinafter, the RFID tag is simply referred to as “tag”. The tag reader unit 19 has an anti-collision function so as to be compatible with a plurality of tags. As the anti-collision function, typical algorithms such as a binary tree method and an Aloha method are known.

  Moreover, the portable information terminal 10 has a UID storage unit and an identification information storage unit as exemplified by the storage memory 12 as a main feature of the present invention. The UID storage unit stores UIDs of a plurality of tags. The identification information storage unit stores identification information including a specific group number and a specific identifier number in association with each of the plurality of UIDs stored in the UID storage unit. The storage memory 12 only needs to be able to be registered in advance in association with the UID and the identification information and to be readable from the control unit 11.

  The control unit 11 includes a UID recognition unit and a determination unit as main features of the present invention, and the portable information terminal 10 includes a warning unit that can be controlled by the control unit 11. The UID recognition unit reads identification information corresponding to the UID read by the tag reader unit 19 from the identification information storage unit, and recognizes the group number and identifier number of the tag received by the tag reader unit 19. The UID recognition unit classifies the received UIDs into a specific group number and identifies them by a specific identifier number when executing the carried item confirmation process after registration in the storage memory 12. is there. The determination unit determines whether the user has forgotten from the recognition result of the UID recognition unit, and the warning unit issues a warning of forgetting based on the determination result of the determination unit.

  The UID recognizing unit / determination unit stores a program or fixed data for causing the CPU to execute such recognition processing / determination processing in the ROM, and the CPU reads out and executes it on the RAM as an execution area. This can be implemented. In addition, as the warning unit, a speaker 15 and / or a display unit 14 are provided. Further, a process for controlling the speaker 15 to emit a warning sound and a process for controlling the display unit 14 to execute a warning display are performed by the CPU. It is preferable to store a program, fixed data, and the like to be executed in the ROM so that the CPU can read and execute the program on a RAM as an execution area.

  Further, in the control unit 11, a condition specifying unit is incorporated so as to be executable like the UID recognition unit. This condition designating unit designates the content condition of the identification information as the content condition of the UID that needs to be read by the tag reader unit 19. The inclusion conditions specified here may be stored in the storage memory 12, and may include conditions such as including a specific group number and one or more specific identifier numbers included in the group number. It may be a condition designated for the group number or a condition designated exclusively. In addition, as a UID content condition that needs to be read by the tag reader unit 19, the condition designation unit designates the content condition of the identification information, but the other part of the control unit 11 directly sets the UID, UID, identifier number, and group number. It may be specified as the inclusion condition, and the condition specifying unit may not function unless this condition is satisfied.

  The determination unit reads the content condition of the identification information specified by the condition specifying unit from the storage memory 12, and determines whether the content condition is satisfied from the recognition result of the UID recognition unit. If the result of determination by the determination unit is not applicable, the warning unit issues a forgetfulness warning.

  In addition, the condition specifying unit stores in advance a plurality of content conditions that can be specified in the storage memory 12, and the Bluetooth (registered trademark) communication unit 17 among the plurality of communication units 20 is connected from the plurality of content conditions. It is preferable to specify (select) the inclusion conditions suitable for the established communication unit 20. The inclusion condition may be set by simply registering the communication unit 20 and the group number (and identifier number) in association with each other. For example, when communication with a certain communication unit 20 is established for all the communication units 20, a UID having a certain identifier number is specified as the inclusion condition from among UIDs in a certain group. The communication unit 20, the group number, and the identifier number are registered in association with each other. Then, the group number and the identifier number associated with the actually connected communication unit 20 may be specified as the inclusion condition.

  Also, in this form, the Bluetooth (registered trademark) communication unit 17 sends a warning request to the communication unit 20 to issue a forgetting warning if the result of determination by the determination unit is not applicable. It is preferable to transmit. As a result, a warning can be issued from the warning unit provided in the communication unit 20.

  In addition, it is preferable to indicate to the user that not only a warning but also a forgetfulness is present. For this reason, the portable information terminal 10 preferably includes a notification unit that can be controlled by the control unit 11. If the result of the determination by the determination unit described above is applicable, this notification unit issues a confirmation (authentication) notification that the user has not forgotten. As with the warning unit, this notification unit not only emits a notification sound (a sound different from the warning sound) from the speaker 15 but also displays on the display unit 14 that it has not been forgotten. Good.

  Next, the communication unit 20 will be described. The communication unit 20 is a unit installed in, for example, a house or a car according to the type of going out, and includes a CPU that controls the entire apparatus, a ROM that stores control programs, fixed data, and the like, and a work storage area for the CPU.

It consists of a corresponding sensor.

  The Bluetooth (registered trademark) communication unit 27 enables wireless communication in which the mobile communication terminal 27 is a master (master communication device) and the portable information terminal 10 is a slave (slave communication device). When the operation detection unit 28 detects the above-described predetermined operation, the Bluetooth (registered trademark) communication unit 27 issues a connection request to the portable information terminal 10, and the connection request to the portable information terminal 10 is established. When established, the unique information of the communication unit 20 is transmitted to the portable information terminal 10.

  As described above, the Bluetooth (registered trademark) communication unit 27 has a connection request function with respect to the Bluetooth (registered trademark) communication unit 17. Actually, mutual communication is established by this connection request function, and the Bluetooth (registered trademark) device address (master communication device) defined in the Bluetooth (registered trademark) packet is an example of the above-described unique information. 10 is transmitted.

  On the mobile information terminal 10 side, the Bluetooth (registered trademark) communication unit 17 recognizes this device address (address detection) to identify the communication unit 20 to be communicated. The condition designating unit refers to the storage memory 12, recognizes the group number of the carry-on group corresponding to the device address, reads the inclusion condition of the identification information associated with the group number, and targets the inclusion condition Select the specific identifier number.

  The determination unit determines whether a part of the UIDs of the plurality of tags read by the tag reader unit 19 (the extracted UIDs that have been read) meets the condition (warning condition) of the selected specific identifier number. If the warning condition is met, the warning unit issues a warning that the speaker 15 or the like is forgotten, and the Bluetooth (registered trademark) communication unit 17 issues a warning request to the communication unit 20, and the communication unit 20 requests the request. And a warning about forgetting it is given by the speaker 25 or the like. In addition, if the determination unit also makes a determination on the confirmation notification condition that there is no forgetting, and it corresponds to the confirmation notification condition, that is, if the determination unit determines the warning condition for forgetting and does not correspond to forgetting to hold The notification unit performs confirmation notification by, for example, emitting an authentication sound from the speaker 15. At the same time, the Bluetooth (registered trademark) communication unit 17 may issue a confirmation notification request to the communication unit 20, and the communication unit 20 may receive the request and issue a confirmation notification using the speaker 25 or the like.

  In the form in which the portable information terminal 10 issues a warning request (/ confirmation notification request), the communication unit 20 may be provided with a warning unit (/ notification unit) in order to answer the request. When the warning unit (/ notification unit) receives a warning request (/ confirmation notification request) from the portable information terminal 10 after the Bluetooth (registered trademark) communication unit 27 transmits the unique information, the warning unit (/ notification unit) Alternatively, a warning (/ authentication) is issued by causing the display unit 24 to sound a warning sound (/ authentication sound) or to display that effect.

  After the user completes the operations of “ID registration” and “device address registration”, the user designates “start operation of management system (carried goods confirmation system)” from the operation menu of the portable information terminal 10, and tags 31 to 31 35, 41, 42, 51, and 52 are sandwiched (inserted) between individual items to be carried.

  Next, the carried item confirmation processing in the system configuration 30 in FIG. 3 and the system configuration 40 in FIG. 4 will be described with reference to FIGS. Here, as the inclusion condition of the UID that needs to be read by the tag reader unit 19, the UID or the UID, the identifier number, and the group number are designated as the inclusion condition, and the condition designation unit is prevented from functioning unless this condition is satisfied. As a condition for including the UID, (I) including a tag 51 for a door key of a group number 0 and not including a tag 52 for a car key, (II) for a key of a front door of a group number 0 It is assumed that the storage memory 12 stores the tag 51 and the tag 52 for the car key. Further, it is assumed that the device address of the communication unit 20 for going out outside the car / outing by car is associated with the group number 1/2 and stored in the storage memory 12. Then, based on the device address of the communication unit 20 that has performed communication, (I) is selected when going out of the vehicle, and (II) is selected when going out of the vehicle.

  In addition, the inclusion conditions that can be specified by the condition specifying unit are either (Ii) not including the UID in the identifier number 1 of the group number 1, or (I-ii) either the UID in the identifier number 2 of the group number 1 Including (I-iii) including all UIDs in identifier number 3 of group number 1, (II-i) not including UIDs in identifier number 1 of group number 2, (II-ii) group number 2 including all the UIDs in the identifier number 2 of (2) and (II-iii) including any one of the UIDs in the identifier number 3 of the group number 2 is stored in the storage memory 12. Then, based on the device address of the communication unit 20 that has performed communication, the inclusion conditions (Ii) to (I-iii) for the group number 1 are selected when going outside the vehicle, and the inclusion conditions for the group number 2 are selected when going outside the vehicle. Conditions (II-i) to (II-iii) are selected.

  First, the carried item confirmation processing in the system configuration 30 of FIG. 3 will be described with reference to FIGS. 6 and 7. When the sensor detects opening / closing of the entrance door or passing through / locking operation of the key (YES in step S21), the control unit 21 controls the Bluetooth (registered trademark) communication unit 27 serving as a master communication device to connect to the connection partner (slave). "Communication device" is called (step S22). Here, if the device address of the connection partner is not known, “inquiry” may be performed. When a connection between Bluetooth (registered trademark) is established by a response from the portable information terminal 10 that is a slave communication device (YES in step S23), the packets are exchanged, and the device address of the communication unit 20 is set to the portable information terminal. 10 is acquired (step S24). If NO in step S23, the connection is not established, so an error is displayed and the process returns to step S21 to wait for sensor input.

  The control unit 11 is a request from the master communication device at the entrance / exit registered in the storage memory 12 from the device address acquired in step S24, and the carry-on goods group corresponding to the device address is group number 1. Is detected (step S25). Subsequently, the control unit 11 reads out the content condition (I) of the UID associated with the group number 1 and the content conditions (Ii) to (I-iii) of the identification information from the storage memory 12, UID and identifier number are selected (step S26). At the same time, the control unit 11 activates the tag reader unit 19 (step S27), and the tag reader unit 19 transmits a radio wave from the RFID antenna 18 (step S28), and a plurality of tags in a range of approximately several tens of centimeters. Is received and read (step S29).

  Next, the control part 11 performs the alerting | reporting process illustrated in FIG. 7, returns to step S21, and prepares for the next going out. In this notification process, the content condition (I) is first verified. In the UID received in step S29, it is determined whether there is a UID that is a reference for going out, that is, a UID of a door key tag 51 and a car key tag 52 (step S31). Furthermore, when the determination result does not indicate going out by car (NO in step S32), the processes of subsequent steps S33 to S37 are executed. If NO in step S31 and YES in step S32, the notification process is terminated.

  That is, in steps S31 and S32, a part of the plurality of tags read corresponds to the UID registered in the identifier number 1 of the group number 0 and the door key tag 51 and further to the car key tag 52. If not applicable, it is determined that the person is going out for the purpose of going to work, and the processes of subsequent steps S33 to S37 are executed. On the other hand, when it does not correspond to the UID registered in the identifier number 1 and the tag 51 for the entrance door key, it is the opening / closing of the entrance door that is not going out, and when it corresponds to the tag 52 for the car key, it is operated. Since it is going out for the purpose, the subsequent processing is not performed.

  As described above, the portable information terminal 10 starts carrying goods confirmation processing triggered by the acquisition of the device address from the communication unit 20, but the user feels bothered by giving a warning or confirmation notification in all the obtained scenes. Therefore, only a necessary scene (here, when going out for the purpose of going to work) is warned or confirmed.

  Next, the control unit 11 verifies the content condition (I-i). The control unit 11 determines whether or not there is a UID indicating that the portable information terminal 10 is not held in the read plural tags (step S33). When a part of the read plural tags corresponds to the UID registered in the identifier number 1 of the group number 1, the identifier number 1 is an identifier attached to the tag 31 indicating the location of the charger for charging the portable information terminal 10. If the portable information terminal 10 detects the tag 31 associated with this identifier, it can be interpreted that the user has come to the entrance / exit without having the portable information terminal 10. Accordingly, if there is a UID for confirming that the portable information terminal 10 is not possessed in step S33, it is immediately determined that the portable information terminal 10 has been forgotten, and the portable information terminal is connected by the connection between Bluetooth (registered trademark). The ten speakers 15 and the speaker 25 of the communication unit 20 emit a warning sound that is forgotten to hold (step S36), and the process ends.

  If it is determined in step S33 that it does not exist, that is, if it does not correspond to the UID registered in the identifier number 1, the control unit 11 verifies the inclusion condition (I-ii), that is, possesses the portable information terminal 10 It is determined whether there is no UID to be shown (step S34). If some of the read tags do not correspond to any of the UIDs registered in the identifier number 2 of the group number 1, the identifier number 2 is a tag 32 indicating the location of the bag for taking out the portable information terminal 10 at work or This is an identifier attached to the tag 33 indicating the location of the pocket of the mobile phone. The fact that the mobile information terminal 10 does not detect any tag 32, 33 associated with this identifier means that the user does not carry the mobile information terminal 10. It can be interpreted as coming to the entrance / exit.

  Therefore, if no possession confirmation UID exists in the portable information terminal 10 in step S34, it is immediately determined that the user has forgotten to carry it, and the connection of the Bluetooth (registered trademark) causes the portable information terminal 10 to The speaker 15 and the speaker 25 of the communication unit 20 emit a warning sound that is forgotten to hold (step S36), and the process ends.

  If it is determined in step S34 that at least one possession confirmation UID of the portable information terminal 10 exists, that is, if any of the UIDs registered in the identifier number 2 is satisfied, the control unit 11 determines that the inclusion condition (I− iii) is verified, that is, it is determined whether or not all UIDs of carry-on items necessary for going out for work are included (step S35). When a part of the read plural tags does not correspond to all of the UIDs registered in the identifier number 3 of the group number 1, the identifier number 3 is a tag 34 indicating a regular place that is a carry-on item of the portable information terminal 10 at the time of work. This is an identifier attached to the tag 35 indicating the location of the wallet, and the fact that the portable information terminal 10 does not detect all the tags 34 and 35 associated with this identifier means that the user does not carry these items. It can be interpreted as coming to the entrance / exit.

  Accordingly, if at least one of the UIDs of carry-on items necessary for going out for work is not present in step S35, it is immediately determined that the carry-on items have been forgotten, and the connection between Bluetooth (registered trademark) Thus, a warning sound forgetting to be emitted is emitted from the speaker 15 of the portable information terminal 10 and the speaker 25 of the communication unit 20 (step S36), and the process is terminated. In this case, since the portable information terminal 10 itself is possessed, the control unit 11 may display a warning such as displaying the name of the carried item on the display unit 14 of the portable information terminal 10.

  If it is determined in step S35 that all the UIDs of the carry items necessary for going out for work are present, that is, if all the UIDs registered in the identifier number 3 are met, the portable information terminal 10 and the carry items are forgotten. Can be interpreted as not happening. Therefore, under the control of the control unit 11, an authentication notification sound is emitted from the speaker 15 of the portable information terminal 10 by connection between Bluetooth (registered trademark) (step S37).

  Thus, for example, let's go out with another bag instead of holding the bag containing all of the portable information terminal 10, the key of the front door (attached with the tag 51), the regular (tag 34) and the wallet (tag 35). Or trying to go out in another suit without wearing the suit with the portable information terminal 10, the front door key (tag 51), the regular (tag 34) and the wallet (tag 35). Even when the user is present, the user can know that he / she has forgotten to bring the portable information terminal 10 and his / her personal belongings because the authentication notification sound cannot be heard from the bag to be taken out or the pocket of the suit.

  As described above, the system configuration 30 assumes prevention of forgetting to take a portable information terminal and carry-on items when going to work. The identifier number and the number of elements are not limited to this.

  Next, the carried item confirmation process in the system configuration 40 of FIG. 4 will be described with reference to FIGS. 6 and 8. When the sensor senses opening / closing or ignition operation of the car (YES in step S21), the control unit 21 controls the Bluetooth (registered trademark) communication unit 27 serving as a master communication device, and the connection partner (slave communication device). “Call” is executed (step S22). Here, if the device address of the connection partner is not known, “inquiry” may be performed. When a connection between Bluetooth (registered trademark) is established by a response from the portable information terminal 10 that is a slave communication device (YES in step S23), the packets are exchanged, and the device address of the communication unit 20 is set to the portable information terminal. 10 is acquired (step S24). If NO in step S23, the connection is not established, so an error is displayed and the process returns to step S21 to wait for sensor input.

  The control unit 11 is a request from the master communication device mounted on the vehicle registered in the storage memory 12 from the device address acquired in step S24, and the carry-on goods group corresponding to the device address is group number 2. This is detected (step S25). Subsequently, the control unit 11 reads out the content condition (II) of the UID associated with the group number 2 and the content conditions (II-i) to (II-iii) of the identification information from the storage memory 12, and A target UID and identifier number are selected (step S26). At the same time, the control unit 11 activates the tag reader unit 19 (step S27), and the tag reader unit 19 transmits a radio wave from the RFID antenna 18 (step S28), and a plurality of tags in a range of approximately several tens of centimeters. Is received and read (step S29).

  Next, the control part 11 performs the alerting | reporting process illustrated in FIG. 8, returns to step S21, and prepares for the next going out. In this notification process, the content condition (II) is first verified. It is determined whether or not the UID that is a reference for going out in the UID received in step S29, that is, the UIDs of the door key tag 51 and the car key tag 52 exists (step S41). Furthermore, when the determination result indicates going out by car (YES in step S42), the processes of subsequent steps S43 to S47 are executed. If NO in step S41 and NO in step S42, this notification process is terminated.

  That is, in steps S41 and S42, a part of the plurality of tags read corresponds to the UID registered in the identifier number 1 of the group number 0 and the door key tag 51, and further to the car key tag 52. When it corresponds, it judges that it is going out for the purpose of driving, and processing of subsequent Steps S43-S47 is performed. On the other hand, when it does not correspond to the UID registered in the identifier number 1 and the tag 51 for the key of the front door, the vehicle door is not opened and the subsequent processing is not performed.

  As described above, the portable information terminal 10 starts carrying goods confirmation processing triggered by the acquisition of the device address from the communication unit 20, but the user feels bothered by giving a warning or confirmation notification in all the obtained scenes. Therefore, only a necessary scene (here, when going out by car) is warned or confirmed.

  Next, the control unit 11 verifies the content condition (II-i). The control unit 11 determines whether or not a UID indicating that the portable information terminal 10 is not held exists in the read plural tags (step S43). When a part of the read plural tags corresponds to the UID registered in the identifier number 1 of the group number 2, the identifier number 1 is an identifier attached to the tag 31 indicating the location of the charger for charging the portable information terminal 10. If the portable information terminal 10 detects the tag 31 associated with this identifier, it can be interpreted that the user starts driving without carrying the portable information terminal 10. Therefore, if there is a UID for confirming that the portable information terminal 10 is not possessed in step S43, it is immediately determined that the portable information terminal 10 has been forgotten and the portable information terminal 10 is connected by the connection between Bluetooth (registered trademark). 10 speaker 15 and speaker 25 of communication unit 20 emit a warning sound forgetting to hold (step S46), and the process is terminated.

  If it is determined in step S43 that it does not exist, that is, if it does not correspond to the UID registered in the identifier number 1, the control unit 11 verifies the inclusion condition (II-ii), that is, carries an essential carrying item during operation. It is determined whether or not the indicated UID exists (step S44). When a part of the read plural tags does not correspond to the UID registered in the identifier number 2 of the group number 2, the identifier number 2 is added to the tag 41 indicating the location of the license that is a portable item of the portable information terminal 10 at the time of driving. The fact that the portable information terminal 10 does not detect the tag 41 associated with this identifier can be interpreted that the user starts driving the vehicle without carrying this personal belonging (license).

  Accordingly, if there is no UID indicating an essential carry-on item during operation in step S44, it is immediately determined that the carry-on item has been forgotten, and the portable information terminal is connected by the connection between Bluetooth (registered trademark). 10 speaker 15 and speaker 25 of communication unit 20 emit a warning sound forgetting to hold (step S46), and the process is terminated. In this case, since the portable information terminal 10 itself is possessed, the control unit 11 also displays a warning display such as causing the display unit 14 of the portable information terminal 10 to display the name of the item (license here). It is good to do.

  If it is determined in step S44 that there is a UID indicating an essential carry item during operation, that is, if the UID registered in the identifier number 2 is satisfied, the control unit 11 verifies the content condition (II-iii), that is, It is determined whether or not at least one UID of carry-on goods necessary for using the toll road is included (step S45). If a part of the read plural tags does not correspond to any of the UIDs registered in the identifier number 3 of the group number 2, the identifier number 3 is a carry item of the portable information terminal 10 when driving on a toll road when going out by car. It is an identifier attached to the tag 35 indicating the location of the wallet or the tag 42 indicating the location of the ETC card, and the fact that the portable information terminal 10 does not detect any of the tags 35 and 42 associated with this identifier Can be interpreted to start driving without carrying these items.

  Accordingly, if none of the UIDs of the carry items necessary for using the toll road exists in step S45, it is immediately determined that the carry items have been forgotten, and are carried by the connection between Bluetooth (registered trademark). The forgotten alarm sound is emitted from the speaker 15 of the information terminal 10 and the speaker 25 of the communication unit 20 (step S46), and the process ends. In this case, since the portable information terminal 10 itself is possessed, the control unit 11 may display a warning such as displaying the name of the carried item on the display unit 14 of the portable information terminal 10.

  If it is determined in step S45 that one of the UIDs of the carry goods necessary for using the toll road exists, that is, if any of the UIDs registered in the identifier number 3 is met, the portable information terminal 10 and the carry goods It can be interpreted that no forgetfulness has occurred. Therefore, under the control of the control unit 11, an authentication notification sound is emitted from the speaker 15 of the portable information terminal 10 by connection between Bluetooth (registered trademark) (step S47).

  Thus, for example, the portable information terminal 10, the front door key (attached to the tag 51), the car key (tag 52), the license (tag 41), the wallet (tag 35) or the ETC card (tag 42) are placed in the same place. If it is left behind, the user cannot hear the authentication notification sound, so that the user can know that he / she has left the portable information terminal 10 and his / her carry-on item. Carrying goods essential for driving and those required for using toll roads may be simultaneously determined and processed as “carrying goods necessary for driving”, but in steps S44 and S45, priority is given. Is running.

  As described above, the system configuration 40 assumes prevention of forgetting to take a portable information terminal and a carried item during driving. The identifier number and the number of elements are not limited to this.

  Further, the carried item confirmation system according to the present invention is not limited to the number of units and the group number of the system configuration illustrated in FIGS. 3 and 4. Furthermore, although the examples of FIGS. 3 and 4 have been described separately, it can be fully understood that the system can cope with both when going out in a car and when going outside a car.

  In addition, in the carried item confirmation system according to the present invention, a wireless communication function other than the Bluetooth (registered trademark) communication function is realized by a wireless LAN (a wireless LAN MAC address is used as a Bluetooth (registered trademark) device address) or the like. May be. However, at present, the wireless LAN is used for an application that requires a higher transmission speed than Bluetooth (registered trademark) and consumes a large amount of power. Therefore, it is preferable to adopt the Bluetooth (registered trademark) communication function.

  As described above, in the carried item confirmation system according to the present invention, it is possible to prevent forgetting to take a portable information terminal and other necessary carried items according to the type of going out from the UID of the tag attached to the carried item.

  In addition, the carried item confirmation system according to the present invention includes a portable information terminal 10 and a portable device that do not include a wireless communication unit for communicating with the communication unit 20 even when the communication unit 20 is not used as described above. It can be applied only by the tag attached to the product.

  For example, when the user presses a predetermined key of the portable information terminal 10 (for example, a drive mode key on a mobile phone or an outing mode key provided separately), the user is out of the car or out of the car Can be determined. As inclusion conditions that can be specified, the drive mode key is associated with group number 1 in FIG. 3 and the outing mode key is associated with group 2 in FIG. It is not possible to warn of forgetting to take portable information terminal 10 by pressing a predetermined key in response to going out / outing other than car) and specifying the inclusion condition that matches the predetermined key in response to the pressing. It is possible to warn of forgetting to carry items and to carry out authentication notification that all items are possessed. Note that some mobile phones have an original manner mode that can be set by the user, and the transition key to the original manner mode may be handled as the above-described outing mode key.
