Here, the short-distance wireless communication between the parent device 10 and the child device 20 is realized by a communication means such as Bluetooth which is limited to a relatively short-distance range using weak radio waves. The mutual identification numbers are stored in the short-distance wireless communication control unit 8 of the parent device 10 and the short-distance wireless communication control unit 22 of the child device 20, and the communication partner is uniquely specified to perform one-to-one communication. Is supposed to do. As shown in FIG. 2, since the slave unit 20 has a simple configuration having only a vibrator and a short-distance wireless transmission / reception function, it can be made smaller and lighter, and can be manufactured inexpensively and easily. .

Next, the operation of the present system will be described with reference to FIGS. 1 and 2 together with the operation of the owner. First, if the wireless terminal 10 is lost due to misplacement or theft, the owner will
In order to activate the misplacement function, a pre-registered telephone makes a certain number of calls, or a pre-registered sender sends a specific mail.

When a specific call or mail is received from a specific number stored in the storage unit 4, the wireless terminal 10 activates the misplacement function means of the control unit 2 and shifts to the misplacement mode. Specifically, the control unit 2 reads the misplaced message from the storage unit 4, displays it on the display unit 5, and invalidates the key operation.

Further, as a feature of this system, the position data acquisition means of the control unit 2 of the wireless terminal 10 acquires the position data by GPS and outputs it to the position notification mail transmission means. Then, the position notification mail transmission unit reads the destination address and the position notification message stored in advance in the storage unit 4, adds the position information received from the position information acquisition unit to the position notification message, and outputs the position notification mail. Send to the destination address.

The transmitted position notification mail is received by the position information server 30 via the base station 50 and a network such as the Internet, and the position information server 30 receives the position information server 30.
Converts the received location data into location information such as addresses and maps based on a database that associates location data with location information such as place names, addresses, and maps, and sends the addresses to the destination address along with the message. To do. If there is map information, the map information may be added or sent as an attached file.

Then, the mail transmitted via the server 30 receives the information receiving terminal 40 registered as the destination.
The location notification message and the address, the map and the like are displayed according to the HTML received by the information receiving terminal 40. As a result, the owner can know the location of the lost wireless terminal from the information receiving terminal 40.

Further, as a feature of the present system, when the misplacement mode is activated in the wireless terminal 10, the control unit 2 activates the short-range wireless communication control unit 8 and the slave unit via the short-range wireless transmission / reception unit 9. The short-range wireless communication with the machine 20 is started.

Then, when the owner confirms the approximate location of the lost wireless terminal with the information receiving terminal 40, the owner carries the slave unit 20 and heads to the location of the lost terminal. And
It comes close to the location of the lost terminal and transmits the wireless signal from the wireless terminal 10 to the short-distance wireless communication transceiver 21 of the handset 20.
When it is received by the control unit 23, the short-range wireless communication control unit 22 sends data notifying that the signal from the base unit has been received.
The control unit 23 vibrates the vibrator 24. When the signal from the master unit is no longer received, the vibration of the vibrator 24 is stopped. The owner can recognize that the wireless terminal 10 is near by the vibration of the child device 20.

At the same time, the control unit 23 of the slave unit 20 outputs an instruction to the short-range wireless communication control unit 22 to output a response signal to the master unit, and the short-range wireless communication control unit 22
A response signal is transmitted to the wireless terminal 10 via the short-range wireless communication transceiver 21.

When the wireless terminal 10 receives the response signal from the handset 20 in the short-range radio transmitter / receiver 9, the short-range radio communication controller 8 controls the data indicating that there is a response from the handset 20. The control unit 2 causes the speaker 7 to output a specific notification sound or melody at the maximum volume.

Alternatively, the short-distance wireless communication control unit 8 detects the reception level of the response signal, and the control unit 2 changes the strength or tempo of a specific notification sound or melody or the tempo according to the level, and the speaker control unit 7 is selected. You may make it output to.

Therefore, if the owner carries the slave unit 20 and searches for the master unit 10, if the slave unit 20 approaches the master unit, the slave unit 20 vibrates and the master unit 10 is near. Further, since the base unit 10 also outputs the notification sound according to the response signal from the handset unit 20 at the maximum volume or the strength or tempo according to the reception level, the direction and distance of the lost base unit 10 can be known. The parent device 10 can be easily found. The operation of this system is performed in this manner.

Next, the operation of each unit will be specifically described. First, regarding the operation of the wireless terminal (base unit) 10, FIG.
Will be explained. FIG. 3 is a flowchart showing the operation of the control unit 2 of the wireless terminal 10 when the misplacement function is activated. As shown in FIG. 3, the control unit 2 continues to call from a telephone number stored in advance in the storage unit 4 a fixed number of times or whether a specific mail is received, as in the conventional case. Is checked to determine whether to activate the misplaced function (100).

When the misplacement function is activated, the control unit 2 activates the misplacement function (102) and shifts to the misplacement mode. Then, as a feature of this device, the control unit 2 starts the output of the short-distance communication signal to the handset 20 via the short-distance wireless communication control unit 8 and the short-distance wireless transmission / reception unit 9 (103).

Further, the control unit 2 activates the position data acquisition means such as GPS (104), acquires the position data of longitude / latitude (106), and sends the destination address and the position notification message from the storage unit 4. The position notification mail data is read out and created together with the position data (108), and the position notification mail is transmitted to the destination address stored in the storage unit 4 (110). Here, the destination address is the address of the information receiving terminal 40 shown in FIG. When a plurality of destination addresses are registered, the position notification mail is transmitted to all the addresses.

Then, the control unit 2 judges whether the transmission of the position notification mail has been normally completed (112), and if it is not normal, the process returns to the processing 110 and the mail is transmitted again. Then, when the transmission is normally completed, the processing is ended.
It should be noted that the wireless terminal 10 stops transmitting the short-range communication signal to the child device 20 when the owner discovers the wireless terminal 10 and performs a specific operation such as releasing the misplaced function.

Thus, in the wireless terminal of this system,
When the misplacement function is activated, it acquires its own location information and sends it by email to a specific destination (information receiving terminal 4
Since it is surely transmitted to 0), it is possible to inform the location of the user to the outside and make it easier for the owner to find the lost terminal.

Next, the operation of the child device 20 will be described with reference to FIG.
Will be explained. FIG. 4 is a flow chart showing the processing of the control unit 23 of the child device 20. As shown in FIG.
Upon receiving the short-distance wireless signal (radio wave) from the wireless terminal (parent device) 10 (200), the child device 20 transmits a response signal to the parent device (202) and vibrates the vibrator 24 (20).
4) Return to step 200 and monitor the reception of radio waves from the master unit.

Then, while the vibrator 24 continues to vibrate while receiving the radio wave of the master unit, and when the radio wave from the master unit is no longer received, the control unit 23 determines whether or not the vibrator 24 is vibrating. If it is vibrating (206), the vibrator 24 is turned off (208), and the process proceeds to step 200 to monitor the radio wave from the master unit. In this way
The process in the child device 20 is performed.

As a result, when the owner carries the child device 20 and approaches the wireless terminal 10, the child device 20 receives a signal from the wireless terminal 10 and vibrates. It is possible to recognize that the terminal 10 is near and easily find it.

Next, the processing when the radio terminal 10 receives the short-distance radio signal from the handset 20 will be described with reference to FIG. FIG. 5 is a flowchart showing the processing of the control unit 2 of the wireless terminal 10 when receiving a short-distance wireless signal from the child device 20. As shown in FIG. 5, the wireless terminal 10
Control unit 2 controls the short-distance wireless signal (radio wave) from the handset 20.
Is received (300), and when it is received, a notification sound is emitted with a corresponding strength or tempo according to the reception level input from the short-range wireless communication control unit 8 (302). ).

Then, the control unit 2 judges whether or not any key is pressed (304), and when the key is pressed, the sounding is stopped (312) and the process returns to the process 300 to continue the monitoring. Further, if the key is not pressed in the process 304, the control unit 2 checks whether a certain time set in the storage unit 4 in advance has passed (whether it has timed out) (306), and if the time is out, If so, the process proceeds to process 312, and if not timed out, process 300
Move to.

If the radio wave from the slave unit 20 is not received in the process 300, the control unit 2 of the master unit determines whether the sound is being produced (310). If the sound is being produced, the process 312 is performed. And the sound is stopped, and if the sound is not sounding, the process returns to step 300 to monitor the radio wave of the handset 20. In this way, the processing of the wireless terminal 10 when receiving the radio wave from the child device 20 is performed. The timeout time in the process 306 can be arbitrarily set in advance by the owner from the menu screen or the like and is stored in the storage unit 4.

Next, a method of registering a destination address in the wireless terminal 10 will be described with reference to FIG. Figure 6
6 is a flowchart showing a method of setting a destination address in the control unit 2 of the wireless terminal 10. FIG. When registering the destination address, the owner selects "register destination address" from the menu screen and inputs the desired address of the information receiving terminal 40 to perform the registration.

As shown in FIG. 6, the control unit 2 judges whether or not "register destination address" is selected from the menu screen (400), and if it is selected, the storage unit 4 is selected.
Display the address registration screen stored in advance in (40
2) When an address is input by an operation from the operation unit 3 (404), the address is stored in the destination address of the storage unit 4 (405), and when the input end is selected (406), an end message is displayed. (408) and the process ends.

When the end key is pressed in the process 406, the control unit 2 finishes the process as it is, and when the other keys are pressed, the process returns to the process 404 and the address input is continued, and a plurality of addresses are continuously input. It is also possible to register. The transmission destination address registered here is the address of the information receiving terminal 40 shown in FIG. 1, and is a destination to which the position notification mail is transmitted when the misplaced mode is activated. In this way, the destination address is registered.

Next, the display screen when registering the destination address will be described with reference to FIG. FIG. 7 is an explanatory diagram showing a display screen when registering a destination address. As shown in FIG. 7, when the “send destination address registration” is selected from the menu or the like, the wireless terminal 10 displays the “message destination for lost message” screen, and the owner is registered at the registration points 1 to 4. When the address of the information receiving terminal 40 is arbitrarily input and the “OK” key is pressed, the control unit 2 stores the input address in the storage unit 4. Multiple destination addresses can be registered, and the position notification mail is transmitted to all registered addresses.

Next, a display example on the information receiving device 40 will be described with reference to FIG. FIG. 8 shows the information receiving device 4.
It is explanatory drawing which shows the example of a display of the position notification mail in 0. As shown in FIG. 8, when receiving the position notification mail transmitted from the wireless terminal 10 via the position information server 30, the information receiving device 40 displays the position notification message and the address on the display unit. In addition, here, the case where the address is transmitted as the position information is shown as an example, but the map information may be displayed, or the address is described in the mail body and the map information is transmitted as an attached file. You may do it.

As a result, even if the owner loses the wireless terminal 10, if he / she performs an operation to activate the misplacement function, the information receiving terminal 40 displays the location as shown in FIG. The wireless terminal can be easily found.

According to the wireless terminal tracking system (present system) of the embodiment of the present invention, the control unit 2 of the wireless terminal 10 activates the misplacement function by a specific incoming call or mail reception registered in advance. Then, position data is acquired by GPS or the like, and the position data is transmitted to the pre-registered address (destination address) of the information display terminal 40 by a position notification mail, and the position information server 30 transmits the position via the Internet. When the notification mail is received, the position data included in the position notification mail is converted into position information such as an address and a map stored in the database in association with each other and transmitted to the information display terminal 40.
However, since the wireless terminal tracking system receives the position notification mail and displays the address of the wireless terminal 10 and the position information of the map, the owner should register the address of the information receiving terminal 40 as a destination address in advance. For example, even if the wireless terminal 10 is lost due to misplacement or theft, a position notification mail notifying the position is transmitted from the lost wireless terminal 10 to the information receiving terminal 40 registered in advance only by activating the misplacement function, Since the location is displayed on the information receiving terminal 40, the owner can easily know the location of the lost wireless terminal and can go to search.

Further, according to this system, the wireless terminal 10
The slave unit 20 that directly performs wireless communication is provided in a one-to-one correspondence with the slave unit 20. When the misplacement function is activated, the control unit 2 of the wireless terminal 10 transmits a short-range wireless communication signal to the slave unit 20. When the handset 20 receives a signal from the wireless terminal 10, it vibrates and notifies the vibrator 24 and outputs a response signal to the wireless terminal 10, and when the wireless terminal 10 receives the response signal, it responds to the reception level. Since it is a wireless terminal tracking system that outputs a notification sound at a fixed volume or tempo,
When the owner carries the mobile device 20 and searches for the wireless terminal 10, the owner can sound the notification sound in different modes according to the distance from the wireless terminal 10, and the owner can vibrate the mobile device 20. Also, there is an effect that the direction and distance of the wireless terminal 10 can be known by the notification sound of the wireless terminal 10, and the lost wireless terminal 10 can be easily found.

Further, when the wireless terminal 10 receives the response signal from the slave unit 20, it may be arranged to output a notification sound at the maximum volume. In this case, when the owner goes to search, Even if you are far away, you can get an idea of where you are and it is easy to discover.

Although the GPS function is used as the position data acquisition means of the wireless terminal 10 here, the base station data of the wireless communication system is not limited to GPS, that is, which base station area the wireless terminal 10 is in. The information may be transmitted as position data to the destination address by a position notification mail. In this case, the position information server 30 stores the identification number of the base station of the wireless communication system and the position information such as the address in association with each other.

Alternatively, in the position information server 30, GP
It is also possible to store both the position data by S and the base station data of the wireless communication system in association with the position information such as an address. In this case, the position data or the base station data from the wireless terminal 10 can be stored. No matter which data is transmitted, the location information server 30 can convert the location information into the corresponding location information and transmit the email including the location information to the information receiving device 40 of the destination, so that the wireless terminal does not have the GPS function. On the other hand, there is an effect that the position notification service can be implemented.

Further, here, the position notification mail is transmitted from the wireless terminal 10 only once when the misplacement function is activated as shown in FIG. 3, but the lost wireless terminal 10 moves. Therefore, it is possible to periodically acquire the position data and send the position notification mail. In such a case, the lost wireless terminal 10
Can be tracked even when the user is moving, which has the effect of further improving convenience.

Furthermore, when the wireless terminal 10 regularly transmits the position notification mail, if the mobile terminal such as PDA (Personal Digital Assistant) is registered as the information receiving terminal 40, the owner can PDA with handset 20
And lost wireless terminal while receiving location information 1
This is more convenient because you can search for 0 and search for a wireless terminal based on the latest position information.

Further, from the information receiving terminal 40 to the wireless terminal 1
When a specific mail requesting transmission of position information is transmitted to 0 and the wireless terminal 10 receives this, the wireless terminal 10 shifts to a mode for periodically acquiring position data, and the information receiving terminal A position notification mail may be sent to the 40. By doing so, the latest position information can be periodically acquired by the operation of the owner, and the convenience can be further improved. effective.

If the slave unit 20 is provided with a mail receiving function and a display function and the address of the slave unit 20 is registered as a destination address, the wireless terminal 10 transmits a position notification mail to the slave unit 20, It is also possible for the handset 20 to receive the mail including the position information via the position information server and display the position information.

Next, a wireless terminal tracking system (another system) according to another embodiment of the present invention will be described.
Another system is a system intended to search for an old man who has a wandering habit, and the system configuration is almost the same as the above-mentioned system, so the illustration thereof is omitted. However, the configuration and operation of the wireless terminal are partly different from those of the system described above.

The wireless terminal of the above-mentioned system acquires position data and sends it by e-mail when the misplacement function is activated, whereas the wireless terminal in another system constantly moves its position at regular intervals. When data is acquired and the position data deviates from a specific range (regional range) registered in advance, this is used as a trigger to send the position information by mail.

The operation of another system will be described. Specifically, it is assumed that the wireless terminal will be carried by an old man with a wandering habit, which is the subject of monitoring. Or, up to this point, the range determined to be able to go out is registered. Then, the control unit periodically performs GPS
The position data (or base station data) by the mobile phone is acquired, compared with the stored range, and when the position data is out of the stored range, the mobile terminal of a family member registered in advance as an information receiving terminal. Or send a position notification email to a personal computer at home. Then, a mail including the position information is transmitted to the information receiving terminal via the position information server, and the whereabouts of the old man is displayed on the terminal.

The message of the position notification mail in another system is as follows: "Mr.
If you store the part other than the address as a position notification message in the storage part of the wireless terminal, the configuration of the position information server is exactly the same as the system described above. It is possible.

In this way, when an old man wanders around and is out of the normal living area, his / her location is notified to the family by e-mail, so that it can be easily tracked.

In addition, when the old man is out of the expected range, it may be urgently needed. Therefore, not only the mail is transmitted, but the wireless terminal transmits its own position data to the position information server. Then, the location information such as the address is obtained from the location information server, and it is synthesized with a prestored message to be converted into voice, and the callee registered in advance is used by the communication line of the existing wireless communication system. It is also possible to automatically make a call and output a message indicating the current location by voice after connecting the line.

In this case, a home telephone, a mobile phone of a family member, etc. can be considered as a call destination. By registering a plurality of calls, it is possible to sequentially call and notify the whereabouts of the old man by a voice message. It can be surely notified.

In this way, even if an old man with a wandering habit is about to go far, he can immediately contact the family and start tracking the old man quickly, which is dangerous. It can be avoided. Furthermore, if both the email transmission and the automatic call by voice message are performed, the receiving family can quickly recognize the need for a search by voice and respond quickly, and can confirm the reliable information by email many times. is there.

Further, similarly to the above-described system, the wireless terminal periodically transmits position data (mail, voice call) to the information receiving terminal, or the position data acquired periodically is the previously acquired data. If the position data is transmitted in a case different from the above, the more accurate location can be notified and the convenience can be improved. In this case, if a portable information receiving terminal is also registered, it is possible to search while receiving the latest position information.

According to the wireless terminal tracking system of another embodiment of the present invention, a specific range is registered in advance in the storage unit of the wireless terminal carried by the wandering elderly person, and the wireless terminal periodically When the position data is acquired and the acquired position data is out of the specific range, the position information server sends the position notification mail including the position data to the registered information receiving terminal, and the position information server receives the position data from the wireless terminal. Since the location information such as an address is converted and sent to the information receiving terminal, and the location information is displayed on the information receiving terminal, if the old person goes out of range, the family will use the information receiving terminal to check the location of the old person. The effect of being able to confirm the position and search, searching more quickly than relying on intuition, protecting the elderly before it hits dangerous eyes, and improving convenience There is.

Further, if the wireless terminal transmits the position data to the position information server, acquires the position information from the position information server, and calls the family telephone by using a normal wireless communication line as a voice message, There is an effect that the whereabouts of the old man can be notified more quickly, the old man can be found in a short time, and danger can be prevented beforehand.

As yet another system, rather than registering a specific area range for each wireless terminal, a specific range (area range) for each wireless terminal is stored in the location information server, The terminal periodically acquires the position information and sends it to the position information server, and the position information server compares the position data received from the wireless terminal with the stored range, and the position data deviates from the specific range. In addition, the location information server transmits the address and the location information of the map corresponding to the location data to the wireless terminal, and when the wireless terminal receives the location information from the server, it calls the callee registered in advance. After connecting the line, a voice message including the position information may be transmitted. In this way, in addition to the effect of the system for the wandering elderly person described above, the amount of data managed by the wireless terminal can be reduced, the position monitoring process in the wireless terminal can be eliminated, and the power consumption can be reduced. effective.
