The schedule registration process performs a process of registering requirements by specifying a date and time.
The item registration process performs a process of registering a name of a necessary item and an identification code for wireless communication corresponding to the item for each requirement registered in the schedule registration process.
When the item search process reaches the date and time indicated by the requirements registered in the schedule registration process, it tries to communicate wirelessly with the terminal with the identification code registered in the item registration process, and when the wireless connection cannot be established with the corresponding terminal. Execute alarm processing.

  By performing processing in this way, schedule registration and item search are performed in conjunction with each other. That is, when a requirement is registered by specifying a date and time in the schedule, items necessary for the requirement are registered. Accordingly, when the date and time indicated in the schedule is reached, for example, when a registered item is left behind, an alarm process is performed, and an appropriate warning can be given to the user.

  According to the present invention, schedule registration and item search are performed in conjunction with each other, and when the date and time of each requirement indicated in the schedule is reached, misplaced items necessary for each requirement, etc. Alarm processing is performed for. Therefore, the user can receive an appropriate warning about an item necessary at the time of daily action only by performing a schedule registration operation.

[1.4 Examples of registration and scan processing]
Next, details of processing examples performed by the schedule management software 31 and the inventory management software 32 built in the mobile phone terminal device 10 will be described in order.
The schedule management software 31 is for a user using the mobile phone terminal device 10 to display a calendar or the like on the display 11 and input and register the scheduled requirements at a scheduled date and time. The schedule management software can register a requirement as a schedule together with a start time, for example, for each date indicated by a calendar. Here, the schedule management software in this example is linked to the inventory management software.
For personal belongings management software, the wireless communication with the wireless tag using the short-range wireless communication circuit 19 is attempted, and the registered item is determined by determining whether the wireless tag can be wirelessly connected to the registered item. It is a judgment that exists. These application softwares are executed based on the control of the control unit 12, and the control unit 12 executes necessary arithmetic processing. Further, data that needs to be registered (stored) by executing these software is stored in the memory 30 or the like. Hereinafter, specific processing will be described in order.

Initially, with reference to the flowchart of FIG. 4, the process example at the time of registering an item in the mobile telephone terminal device 10 is demonstrated.
If it demonstrates along FIG. 4, it will be judged first whether it is the mode which performs the registration about the item which is a possession when a user goes out etc. (step S31). In the item registration mode, the user inputs an item name by a key operation or the like (step S32). Thereafter, it is determined whether or not a registration process for associating any of the wireless tags 2a to 2e with the item whose name is input (step S33), and waits until the registration process is performed. When registration of the wireless tag is started, for example, the wireless tag to be matched is brought close to the mobile phone terminal device 10, and the mobile phone terminal device 10 acquires the terminal ID of the wireless tag that can be communicated at that time. The terminal ID to be stored in the terminal is registered (step S34).

  Up to this point, the registration for one item is completed, and it is determined whether or not to register another item (step S35). If another item is to be registered, the process returns to step S32. When the item registration is finished, the process here is finished.

FIG. 5 is a diagram showing a display example on the display 11 when this item registration is performed.
In this example, “pass case” is entered as the item name, and a list of other item names already registered and the number of registrations are also displayed. In this example, the registered items are “key holder” and “wallet”.
Also, a button for executing registration and a button for returning the screen are displayed.
When the button for executing registration is operated, the screen shifts to a screen display (not shown) for registering the wireless tag in step S34 in the flowchart of FIG.

[1.5 Example of processing when registering schedules and items]
Next, a processing example when registering a schedule and items will be described with reference to the flowchart of FIG.
First, processing for selecting an item to be registered in the schedule is performed (step S11). This item is selected from among the items registered in the flowchart of FIG. 4 described above, for example. Next, from the requirements registered in the calendar by the schedule function, the item selected in step S11 as the requirement to register the item is registered as an item corresponding to the requirement. The requirement registered in the calendar is a requirement that specifies the date and time, and the destination of the requirement and the actions performed by the requirement are registered.
A plurality of items can be registered in one requirement in the schedule.
In addition to the items registered for each requirement, items that are commonly held wherever they go are registered as common registered items.

In the flowchart of FIG. 6, after this registration, the control unit 12 of the mobile phone terminal device 10 determines whether or not to perform a scanning process (step S13), and when not performing the scanning process, waits as it is (step S14). The scanning process here is started, for example, when the mobile phone terminal 10 is set to the registered item search mode.
If it is determined in step S13 that the scan process is to be performed, for example, terminal IDs associated with all currently registered items are acquired from the registration data (step S15). Then, the wireless communication in the short-range wireless communication circuit 19 is started, a process for determining whether or not the wireless communication with the wireless tag of the acquired terminal ID has been performed is performed, and the wireless tag search process is performed (step S16). ).

  In this search process, it is determined whether the terminal IDs of all necessary items have been detected (step S17). If the terminal IDs of all items have been detected, for example, the display 11 indicates that all items are present. (Step S18). If at least one necessary item terminal ID is not detected in step S17, an alarm process is performed, for example, to indicate that the necessary belongings do not exist nearby (step S18). At this time, for example, the registered name of an item that does not exist nearby is displayed. Also, the registered item name may be output by voice to perform alarm processing. Display and audio output may be used in combination.

Next, a processing example when an item is registered in the requirements in the schedule will be described with reference to the flowchart in FIG.
The control unit 12 determines whether or not the current date and time has become the start date and time of any requirement registered in the schedule (step S21). Here, when it is not the start date and time of any requirement, it waits until it becomes a start date and time. In step S21, it is determined whether or not it is the start date / time of the requirement. However, it may be determined that the time is earlier than the start date / time of the requirement (for example, 10 minutes before).
When the start date / time of any requirement is reached (or when it is a predetermined time before the start date / time), a terminal ID corresponding to the item registered in the requirement is acquired (step S22), and the terminal ID The wireless tag search process is performed (step S23). At this time, if there is an item that is commonly registered apart from the schedule, a search process for a wireless tag of a terminal ID corresponding to the commonly registered item is also performed.
Then, it is determined whether or not all searched wireless tags have been detected (step S24). If all the tags have been detected, it is displayed on the display 11 that there are belongings (step S25). If at least one terminal ID of a necessary item is not detected in step S24, an alarm process is performed, and for example, the display 11 displays that there is no necessary belonging nearby (step S26). At this time, for example, the registered name of an item that does not exist nearby is displayed. Moreover, you may output the item name which does not exist with an audio | voice.

  FIG. 8 is an example of a screen displayed on the display 11 by starting the belonging management software. “Property tracker” indicating property management software is displayed, and each item is displayed in order. In this example, “daily inventory list” indicating common registration items, “registration to calendar” for processing to be registered in the schedule, “scan execution” for processing to search for registered items, and date and time for scanning are set. Items such as “Alarm Set” are displayed.

FIG. 9 shows an example of a screen displayed on the display 11 at the time of schedule registration.
In this example, the requirements for each date are displayed in a list. Here, regarding the requirement that the item is registered, the display of “item alarm” is indicated by characters (or some mark).

FIG. 10 shows an example of a screen displayed on the display 11 when all registered items are detected when scanning is executed by a user operation.
In this example, “scan execution” indicating that the scan has been executed is displayed, and then it is displayed that “all are near” can be detected. In this example, a list of names of items that can be detected is displayed.

FIG. 11 shows an example of a screen displayed on the display 11 when some or all of registered items cannot be detected when scanning is performed by a user operation.
In this example, “scan execution” indicating that the scan has been executed is displayed, and the name of the item that has not been detected is displayed prominently. Specifically, “No document file” is displayed. A list of detected items is also displayed at the same time.

FIG. 12 shows an example of data registered as a schedule and stored in the memory 30.
As the schedule data, the name of the requirement is registered for each date in time units, and when there is a registered item, the registered item name is also registered as additional information. In addition to registration in units of schedules, information on common registration items is also registered.

FIG. 13 shows a display example when the date and time when the requirement is registered is reached (or when the time is approaching) in execution of schedule management.
In this example, it is an example when it is time to leave the house, the date and time of leaving the house are displayed, and among the items registered in the requirements at this time and the common items, items that are not detected The name is displayed. Simultaneously with this display, the display content may be output by speech synthesis, or an alarm sound for warning may be output.

  FIG. 14 is a display example when the date and time when the requirement is registered (or approaching the time) in the execution of schedule management as in the example of FIG. 13. In the case of FIG. 14, This is an example in which a list of detected item names is displayed simultaneously.

  In this way, items are registered for each requirement in the schedule, and by searching for items in conjunction with the schedule management, the user is automatically warned whether he / she has appropriate items for each requirement. Will be. Therefore, it is possible to effectively prevent accidents such as forgetting necessary belongings and going out. In addition, since the items that are carried around in common are registered as common items when going out, it is not necessary to individually register them in the schedule, which is convenient for the user.

[1.6 Example of processing when deleting registered items]
The flowchart of FIG. 15 shows a processing example when deleting a registered item.
Referring to the flowchart of FIG. 15, it is first determined whether or not it is a mode for deleting a registered item (step S41). If it is a mode for deleting a registered item, an item to be deleted is selected by a user operation from a list of registered items (step S42). Then, it is determined whether or not there is a user operation for confirming the deletion of the selected item (step S43). If there is a confirmation operation, the corresponding item is deleted (step S44). When any item is deleted, when the deleted item is registered in the schedule or the like, the corresponding item is not registered in the schedule.

  If the confirmation operation in step S43 is not performed, it is determined whether or not to delete the item (step S45). If not, the process returns to the selection process in step S42. Return.

[2. Modification of Embodiment]
Next, a modification of the embodiment of the present invention will be described.

[2.1 Example of device status determination]
In the configuration of the wireless tag 50 shown in FIG. 3, only the configuration for communicating with the wireless communication partner is shown, but the wireless tag 50 is provided with a function that can detect the state of the attached item side. You may display the detected state at the time of item search.

The flowchart in FIG. 16 shows a processing example in this case.
First, it is determined whether or not it is time to execute scanning (step S51). When it is time to execute scanning, it is determined whether or not the terminal ID of the item to be searched at that time has been detected (step S52). When the terminal ID is detected, an alarm process is performed (step S53). The alarm process is already described.

When the terminal ID of the item being searched for is detected, it is determined whether or not the state of the device can be detected with the wireless tag of the detected terminal ID (step S54). Here, when the state of the device cannot be detected, only the presence of the device is displayed on the display 11 and the process ends (step S55).
If it is determined in step S54 that the device status can be detected, the device status is acquired by wireless communication with the wireless tag (step S56), and the presence of the device is determined based on the acquired device status information. The state of the device is displayed on the display 11 (step S57).

FIG. 17 shows a display example in this case.
Here, a digital camera is used as a device to search in conjunction with the schedule, and information on the state of the digital camera is displayed. In the example of FIG. 17, the remaining battery level of the digital camera and the remaining capacity of the memory card are acquired, and the message “Remaining battery is low” is displayed and “Remaining memory card is 20 cards”. The display is done. By performing such display, the state of the belongings to be taken out when going out can be known in conjunction with the schedule.

[2.2 Example of warning in advance]
In the explanation so far, the example of performing the scanning process linked to the schedule has been explained, but the state where the belongings are prepared in advance by performing the scan only a predetermined time before the date and time registered in the schedule. You may make it detect and warn.
That is, for example, as shown in the flowchart of FIG. 18, it is determined whether or not a predetermined time has passed from the requirement of the schedule in which the item is registered (step S61). For example, it is determined whether the requirement to go out is one hour before the registered time.
When it is determined that it is a predetermined time before going out (one hour before), a scan process is executed (step S62), and as a result, more than half of the registered items are not detected. (Step S63), an alarm process is performed (Step S64). When more than half of the items registered in the corresponding requirement are detected, alarm processing is not performed because preparations for going out to some extent are in progress.
By giving a prior warning in this way, it becomes possible to warn to prepare for going out.

  Although the system configuration using the mobile phone terminal device has been described so far in the embodiment, the present invention can also be applied to a terminal device having other wireless communication functions. In addition, the display examples shown in the drawings show a preferable example, and are not limited to the illustrated examples.
