  However, in the method as described in Patent Document 1, it is difficult for the elderly or physically handicapped persons to operate the keys of the mobile phone in an emergency. In such a case, the mobile phone is taken out. Sometimes it is impossible. Furthermore, it is uneconomical to have an infant or the like hold a mobile phone for crime prevention. Moreover, even if an e-mail is transmitted from a mobile phone, it is not always notified instantly to a guardian or the like, and a special monitoring system is necessary to cope with an emergency. Furthermore, a device such as a simple security buzzer is not effective when there are no people around.

  Therefore, the present invention has been made to solve the above-described problems, and does not require operation of a portable terminal such as a cellular phone with a GPS function even when a user (person to be protected) falls in an emergency. In addition to the sound of a buzzer terminal that can be operated extremely easily even by infants and people with physical disabilities, etc., the owner (who is in a position to monitor the user such as a guardian) is automatically notified and owned by e-mail and telephone. It is an object of the present invention to provide a portable terminal capable of displaying on a map the position of a portable terminal carried by a human being protected by a person's terminal, and a reporting / searching system thereof. Furthermore, it is an object of the present invention to provide a search system in which the owner can know the user's position at any time from the owner's terminal when the owner wants to know the user's position arbitrarily.

That is, not only in an emergency, the position of the user (person to be protected) can be displayed on the map of the owner terminal by obtaining the position of the wireless portable terminal at an arbitrary timing.

  The functions, operations and effects of the portable wireless terminal and system described above are summarized as follows.

  The wireless portable terminal of the present invention receives a weak radio wave of an emergency signal when a user (or a companion) rings a sub terminal such as a security buzzer. The wireless portable terminal that has received this emergency signal is connected to the service provider's center server by the built-in PHS radio unit, further transmits the nearest PHS base station information, and receives positioning assistance data prepared in advance from the center server. To perform GPS positioning. If the GPS positioning is successful, the latitude / longitude information of the wireless portable terminal is transmitted to the center server and stored. If GPS positioning fails in a case where GPS radio waves do not reach, such as indoors or bad weather, the center server stores latitude / longitude information calculated and corrected based on the nearest PHS base station information of the wireless portable terminal. After the communication between the wireless portable terminal and the center server is completed, the center server transmits a URL storing an emergency notification message and map data to a preset mail address, and displays the corresponding position on the map.

Upon receiving the position search instruction, the center server performs PHS base station information acquisition and GPS positioning request to the wireless portable terminal, and if the GPS positioning is successful, the information is based on GPS, and if the positioning is unsuccessful, the PHS base station A map in which latitude / longitude information calculated and corrected by information is mapped can be generated and displayed on the owner terminal.

  According to the present invention, by bringing a user (including a companion) with a wireless portable terminal and a sub-terminal such as a buzzer, the position of the portable terminal of the user can be automatically set just by sounding the buzzer in an emergency or the like. It is possible to easily construct a system that is automatically notified to an appropriate person by e-mail and telephone and is useful in emergency such as crime prevention or disaster.

  Hereinafter, the present invention will be described using specific embodiments with reference to the drawings.

  FIG. 1 is a diagram showing functional blocks mainly of a wireless portable terminal 10 and a sub-terminal (here, a buzzer terminal 20 will be described as an example) in a preferred embodiment of the present invention. As shown in the figure, the wireless portable terminal 10 includes a control unit 1, a GPS reception unit 2, a position information acquisition unit 3, a position information transmission unit 4, an incoming call response control unit 5, an automatic voice notification unit 6, a weak wireless reception unit 7, The display unit 8, the operation unit 9, the microphone 11, the speaker 12, and the PHS wireless unit 13 are configured. The control unit 1, the GPS receiving unit 2, the weak wireless receiving unit 7, and the PHS wireless unit 13 are connected by a serial IF. Although not particularly shown, it is desirable that the GPS receiver 2 can be controlled to be turned on and off by the controller 1. This is because if the GPS receiving unit 2 always receives radio waves from the satellite, wasteful power is consumed. In addition, the buzzer terminal 20 includes a buzzer unit 21 and a weak wireless transmission unit 22, and performs wireless transmission with the wireless portable terminal 10 using weak radio waves.

  The function of each part of the wireless portable terminal 10 will be further described. The GPS receiver 2 receives a radio wave for positioning the terminal from the GPS satellite 40. The obtained radio waves for positioning are communicated with the center server 50 via the PHS network 80 and the Internet 60 via the provider 70 by the position information acquisition unit 3 to acquire the position information of the wireless portable terminal 10. . The center server 50 is a server of a provider that provides a service using this terminal. Details of this position information acquisition will be described later. The obtained position information is transmitted to the center server 50 by the position information transmission unit 4. Also, the incoming call response control unit 5 makes a call with a telephone number registered in advance, and determines whether or not a normal telephone call is connected. The automatic voice notification unit 6 transmits a voice message stored in advance when the telephone is connected. It is desirable to prepare several types of voice messages. The weak wireless reception unit 7 receives a signal from a weak radio wave from the buzzer terminal 20. In addition, the wireless portable terminal 10 includes a display unit 8, an operation unit 9, a microphone 11, and a speaker 12 that serve as an interface for a user (operator) of the terminal. The display unit 8 may be a general LED, a lamp, or the like, or a small liquid crystal screen. The operation unit 9 may be a key button, a lever, a slide switch, or the like. A control unit 1 (typically a CPU) controls the overall operation of these units.

  As described above, the configurations of the wireless portable terminal 10 and the buzzer terminal 20 have been mainly described as one embodiment of the present invention. However, these configurations are merely typical examples, and variations or sub-combinations of other configurations are also taken. Please understand that you get.

  FIG. 2 is a diagram showing a system configuration in the first embodiment of the present invention. First, when an emergency occurs in the user, an alarm buzzer is generated by operating a switch or lever of the buzzer terminal 20. At this time, an emergency signal is notified to the wireless portable terminal 10 (step S1). The wireless portable terminal 10 that has received the emergency signal connects to the Internet 60 through the provider 70 via the PHS network 80, and communicates with the center server 50 (the center server side also has the PHS communication unit 51) (step S2A). The center server 50 transmits a mail prepared in advance in an emergency (via the mail server 90 used by the owner) to the owner terminal 30 (step S3). This mail includes position information obtained by the wireless portable terminal 10 using the GPS satellite 40 or CS (PHS reference station) 120 in advance. For acquisition of position information using the GPS satellite 40, positioning assistance data obtained by the center server 50 using the GPS reference station 110 is used. By transmitting the positioning assistance data to the wireless portable terminal 10, it is possible to shorten the positioning calculation time of the position information (longitude, latitude, and altitude in some cases) on the wireless portable terminal side. In synchronization with step S2A, a voice automatic emergency call is notified to owner terminal 30 in step S2B. The owner terminal 30 may be a mobile phone in addition to a PC or the like, or a combination of both.

  3 and 4 are diagrams showing an operation flow (part 1) in the first embodiment of the present invention. First, it is assumed that the buzzer terminal 20 transmits an emergency signal (step S105). When receiving the emergency signal in step S106, the wireless portable terminal 10 acquires information on the nearest PHS base station (CS) (step S107). Next, in step S108, data communication with the center server 50 is started. At this time, it is desirable to simultaneously start timer monitoring (step S130) in preparation for a communication error.

  When the center server 50 receives the processing content (emergency call here) sent from the wireless portable terminal 10 (step S109), the center server 50 transmits a position information request to the wireless portable terminal 10 (step S111). In response to the position information request on the wireless portable terminal 10 side (step S110), the PHS base station information acquired in step S107 is transmitted (step S112), and the center server 50 side obtains the later GPS position information. In case it is not stored, it is stored (step S113).

  Next, positioning assistance data for assisting GPS positioning calculation is requested from the wireless portable terminal 10 side to the center server 50 (step S114), and response processing is started on the center server 50 side (step S115). However, steps S114 and S115 may be omitted, and processing may be performed assuming that step S111 also serves as a positioning assistance data request. The center server 50 that has received the positioning assistance data request transmits the positioning assistance data (step S117). Specifically, the positioning assistance data transmitted here includes, for example, GPS Initial Location (initial values such as latitude, longitude, and altitude), GPSTimeOfWork (second of week), GPS Week (week number), GPSEphemeris Count (number of ephemeris satellites), GPSEphemeris <number> (ephemeris data n), GPSEphemeris Satellite ID (satellite number corresponding to ephemeris data n), and the like are included.

  The wireless portable terminal 10 that has received the positioning assistance data in step S116 starts GPS positioning for obtaining its position information using this (step S118). When the GPS positioning (positioning calculation) is completed, the GPS position information is transmitted to the center server 50 (step S119). If the positioning is OK, the latitude, longitude, etc. are transmitted, and the longitude / latitude information is stored on the center server 50 side (steps S120 and S122). Transmit (step S121). When this NG information is received, the latitude / longitude information is stored according to the PHS base station information (step S123). When the above steps are completed, the line with the center server 50 is disconnected (step S124). In addition, by monitoring the timer, the line is disconnected even when steps S108 to S123 are not completed even after a predetermined time has elapsed.

  Next, moving to FIG. 4, the processing after the line is disconnected will be described. The wireless portable terminal 10 waits for the user to end the buzzer (step S125). The center server 50 calculates a position on the map based on the position information transmitted by the wireless portable terminal 10, maps the position on the map, and simultaneously acquires a mail address designated in advance in an emergency (step S126). Further, the emergency message and the URL of the map are included in the mail and transmitted to the owner terminal 30 (step S127). The owner terminal 30 receives this mail in step S131.

  Further, at the same time as or before or after this mail transmission, the wireless portable terminal 10 transmits an automatic voice report (step S128). The owner terminal 30 (which may be a telephone in this case) receives this automatic voice notification (step S132), and can grasp the emergency situation by voice. Further, the owner terminal 30 may send a message confirming display based on the URL of the map to the center server 50 (step S133) and display the map on the center server side (step S129).

  FIG. 5 is a diagram showing a system configuration in the second embodiment of the present invention. The basic system configuration is the same as that of the embodiment of FIG. 2, but in this example, even when an automatic emergency call is not issued from the wireless portable terminal 10, the owner terminal 30 can wirelessly carry it at an arbitrary timing. The position information of the terminal 10 can be obtained.

  Here, first, the location information of the wireless portable terminal 10 is requested from the owner terminal 30 to the center server 50 via the provider 71 on the Internet 60 (step S1). Next, the center server 50 that has received the request connects to the PHS network 80 via the PHS communication unit 51 and communicates with the wireless portable terminal 10 (step S2). Then, the wireless portable terminal 10 requests the center server 50 for positioning assistance data that helps the positioning of its own location information, and the positioning result of the location information is sent over the Internet 60 to the provider 70 (of course, the same as the provider 71). It transmits to the center server 50 via (step S3). The center server 50 returns the obtained position information to the owner terminal 30 (step S4). Although not shown, a voice notification may be simultaneously received at this time. The message at this time may be a message different from that in an emergency.

  By doing so, the owner (guardian) can know the position of the user even in an emergency. Here, the user may be an animal such as a pet as well as a person to be protected (for example, a child, an elderly person, or a disabled person). Of course, the buzzer terminal 20 is not necessary in the case of animals.

  6 and 7 are diagrams showing an operation flow in the second embodiment of the present invention. The basic flow of the system is as follows. First, in FIG. 6, at the owner terminal 30, the owner accesses a predetermined Web page (step S205) and selects position information search (service). At this time, the authentication server 55 performs authentication using an ID and a password (step S206). If the authentication is OK, it is transmitted to the center server 50, and the center server 50 generates a subsequent operation page (step S207).

  The owner terminal 30 causes the center server 50 to start the position information search by pressing a position information search button or the like on the Web page (step S208). The center server 50 acquires the telephone number of the wireless mobile terminal 10 to be searched from the ID or the input screen of the web browser (step S209). Next, the center server 50 issues a call origination request to the server-connected PHS communication unit 51 (step S210). The wireless portable terminal 10 receives this call request as a write mail (step S211). Further, the wireless portable terminal 10 acquires information on the nearest PHS base station (CS) (step S212). When the PHS base station information is obtained, the wireless portable terminal 10 starts data communication with the center server 50 (step S214), and causes the center server 50 to receive the processing content (step S213). The inquiry about work is performed from the wireless portable terminal 10, and the inquiry is received by the center server 50 (steps S216 and S215).

  Next, the center server 50 requests location information to the wireless portable terminal 10 (step S217). The wireless portable terminal 10 responds to this position information request (step S218), transmits the PHS base station information acquired in step S212 (step S220), and accepts this on the center server 50 side (step S219). Next, a positioning assistance data request is transmitted from the wireless portable terminal 10 (step S222), and the center server 50 responds to this request (step S221). However, step S222 and step S221 may be omitted, and the center server 50 may move to step S223 immediately after step S219 and transmit positioning assistance data.

  When the wireless portable terminal 10 receives the positioning assistance data (step S224), it starts GPS positioning using this (step S225 (hereinafter moved to FIG. 7)). When the positioning is completed, the wireless portable terminal 10 transmits the GPS position information (step S226). However, when positioning is OK, latitude / longitude information (and altitude information if necessary) is transmitted as a positioning result (step S228), but positioning NG information is also transmitted when positioning cannot be performed for some reason ( Step S230). The center server 50 stores the positioning result regardless of OK or NG (steps S227 and S229).

  When the above processing is completed, the line between the center server 50 and the wireless portable terminal 10 is disconnected (step S231). In order to monitor a communication error, it is desirable to perform timer monitoring (step S232) for the processes in steps S211 to S229.

  After the line is disconnected, the center server 50 calculates the position on the map and generates a map (step S233), and displays a map near the position of the wireless portable terminal 10 (step S235). In step S234, the owner terminal 30 may receive the map data itself displayed on the center server 50, or may receive only the URL of the map and check the location information by accessing it. Also good.

  FIG. 8 is a diagram summarizing, as an image, the cooperation function of the wireless portable terminal 10 (jacket terminal 10) and the sub terminal (buzzer terminal 20) according to a preferred embodiment of the present invention. Since the entire configuration of the system has already been described with reference to FIGS. 2 and 5, only the outline is shown here. That is, in the event of an emergency of the terminal user of the jacket terminal 10 such as the child and the buzzer terminal 20, the buzzer terminal 20 rings and an emergency notification is made by e-mail from the jacket terminal 10 connected by weak radio waves. At the same time, the position of the jacket terminal 10 is obtained from the GPS satellite 40 or the PHS base station information and included in this e-mail.

  FIG. 9 is a diagram showing a single function of the buzzer terminal 20 according to a preferred embodiment of the present invention. The buzzer terminal 20 in this figure has a simple shape that is easy to operate in an emergency. That is, when the emergency notification lever 23 is pulled, the buzzer sounds, and when the emergency notification lever 23 is pressed, the buzzer stops. If the buzzer can be stopped easily, it will be misreported, so it is desirable to make it difficult to push the lever. The display unit is only the LED 24 indicating that the communication unit is out of battery. This out-of-battery LED 24 may blink at a constant cycle for warning. When manufacturing a battery, for example, a personal computer (PC) 25 for setting is connected to a dedicated interface cable 26, and an individual ID is stored in a flash memory (EEPROM) in the terminal. This ID is set to the same ID as the external ID label attached to the buzzer terminal 20.

  FIG. 10 is a diagram illustrating an operation mode of the buzzer terminal 20. The ID registration mode is a mode for registering the ID of the buzzer terminal 20 in the jacket terminal 10. The ID registration mode is started by turning on a dedicated switch (communication start switch (not shown)) of the buzzer terminal 20. In this mode, the buzzer terminal ID is continuously transmitted to facilitate registration to the jacket terminal 10. The ID registration mode ends with a fixed time or when the communication start switch is turned off. Even when the jacket terminal 10 is not used in pairs (when the jacket terminal 20 is used alone), the registration command is transmitted.

  The normal mode is a mode in which the ID of the buzzer terminal 20 is periodically transmitted to the jacket terminal 10. When the jacket terminal 10 in which the terminal ID is registered is within a range that can be received, it is desirable to display an icon (not shown) indicating that it is linked to the jacket terminal screen. The communication start switch is turned on, and the normal mode is entered after a certain time. Thereafter, the normal mode usually continues until the battery runs out.

  The emergency notification mode is a mode that is activated by pulling the emergency notification lever 23 and continuously transmits an emergency notification command to the jacket terminal 10. Further, by pulling the emergency notification lever 23, an emergency situation of the user of the buzzer terminal 20 is notified to a pre-designated mail address (however, the buzzer terminal 20 needs to be within the reach of the jacket terminal 10). The buzzer terminal 20 continues to transmit the emergency notification until the emergency notification lever 23 is pressed. Rather than stopping the buzzer at the same time as stopping the buzzer, it is better to continue transmitting the emergency notification for a certain time (for example, 1 hour) after the buzzer is stopped. This is because the perpetrator may stop the security buzzer that draws attention to the surroundings.

  In the battery consumption mode, a mode transition is made when it is detected that the built-in battery is consumed below a predetermined value. In this mode, the battery consumption notification command is transmitted to the jacket terminal 10 together with the ID of the buzzer terminal 20 once every few seconds. This mode lasts until the battery is completely exhausted or replaced.

  FIG. 11 is a diagram showing an operation mode of the jacket terminal 10 according to the preferred embodiment of the present invention.

[1 Buzzer terminal connection display]
When the paired buzzer terminal 20 is connected to the jacket terminal 10, this is a function for displaying that fact on the screen. Check the connection at regular intervals, display if connected, delete if not. It is desirable to be able to set the update timing as a parameter.

[2 Buzzer terminal ID registration / deletion]
This is a function for pairing the jacket terminal 10 and the buzzer terminal 20. After setting the buzzer terminal 20 in the buzzer terminal registration mode, the ID registration function is called from the menu operation. A plurality (up to about 10) of buzzer terminals 20 can be paired with one jacket terminal 10.

[3 Buzzer terminal emergency notification server transfer]
This is a function of receiving an emergency notification message issued from the buzzer terminal and notifying the center server 50 of the emergency notification message.
