  However, when a child is taken away, the limb of the person who wants to report may be restrained and the emergency call switch may not be operated.

  Considering such a case, it is preferable to search the mobile communication terminal on the monitoring center side and recognize the occurrence of an emergency. However, in cases such as when a child is taken away, it is considered that the guardian requests a search by not returning home after the return time, and the search time is considerably delayed from the time of occurrence of the emergency, and the search can function effectively. It is possible that there is no.

  Therefore, a mobile communication terminal and an emergency notification system that can execute an emergency notification almost in real time when an emergency occurs without requiring an emergency notification operation are desired.

  In order to solve such a problem, the first aspect of the present invention provides (1) a moving speed detecting means for detecting the moving speed of the portable communication terminal, and (2) detected in the portable communication terminal carried by the person being monitored. An emergency occurrence recognition means for recognizing the occurrence of an emergency based on the moving speed; and (3) an emergency notification means for notifying an external device of the occurrence of an emergency when the occurrence of the emergency is recognized. It is characterized by having.

  The emergency notification system according to the second aspect of the present invention includes the mobile communication terminal according to the first aspect of the present invention and a monitoring device that receives the occurrence notification of the emergency transmitted by the emergency notification means. .

  According to the present invention, since the mobile communication terminal recognizes and notifies the occurrence of an emergency based on its own moving speed, it is almost real time when the emergency occurs without being subjected to an emergency notification operation. Emergency notifications can be executed.

(A) First Embodiment Hereinafter, a first embodiment of a mobile communication terminal and an emergency notification system according to the present invention will be described in detail with reference to the drawings. The emergency communication system of the first embodiment uses a mobile phone system.

  FIG. 1 is a block diagram showing the overall configuration of the emergency notification system 1 according to the first embodiment. In FIG. 1, the emergency notification system 1 of the first embodiment is a base station that appropriately performs communication between a mobile phone 2 that is a mobile communication terminal of the first embodiment and a mobile phone 2 in its own area. 3 and a management center device 5 that accommodates and manages a large number of base stations 3 via the mobile phone network 4, and can communicate with the management center device 5 via a predetermined line 6 such as a public network or a dedicated line. And a monitoring terminal 7 that monitors the state of the mobile phone 2.

  As will be described later, the mobile phone 2 has a function (emergency detection, emergency notification function) for automatically detecting and reporting that a carrier (such as a kindergarten or elementary school student) has entered an emergency. It has a detailed configuration as will be described later. For emergency notification or the like, a standby channel of the mobile phone 2 (a channel in which the mobile phone 2 and the base station 3 communicates while waiting for an outgoing call or an incoming call) may be used. An established call channel may be used, or a special number transmission similar to “110 (police station call)” and “1416 (answering service call)” may be used.

  In the case of the first embodiment, the base station 3 and the mobile phone network 4 have a relay function for giving an emergency notification from the mobile phone 2 to the management center device 5.

  The management center device 5 cooperates with the monitoring terminal 7 to notify the monitoring person that the carrier of the mobile phone 2 has fallen into an emergency. In general, there is a center device that collectively manages which mobile phone 2 is under the control of which base station 3. However, this center device may be used together as the management center device 5 for emergency notification. .

  The management center device 5 has an emergency notification management table 5a configured as shown in FIG. One record of the emergency notification management table 5a includes identification information (phone number, product number, etc.) of the mobile phone 2 that has concluded the emergency notification service, identification information of the base station 3 in which the mobile phone 2 is currently accommodated, emergency An emergency flag indicating whether or not a situation has occurred, an emergency notification time, current location information of the mobile phone 2, a notification method to a notification destination when an emergency occurs (if it is an email, it is an email and an email address In the case of a telephone, a field such as that and a telephone number) is prepared. Here, a plurality of notification methods may be described as a notification method in the event of an emergency, and notification may be made to the next-order notification destination when contact cannot be made. You may make it notify in parallel. The emergency flag, emergency notification time, and current location information fields of the mobile phone 2 are blank before the occurrence of an emergency.

  The monitoring terminal 7 is a communication terminal that is used for communication by a monitor related to the mobile phone 2, and is a terminal that is notified of the occurrence of an emergency by the management center device 5. Here, the monitoring terminal 7 may be a personal computer or other information processing apparatus, or may be a telephone. However, the terminal is preferably a terminal that accepts notification of occurrence of an emergency in real time. A mobile phone having an e-mail communication function is often read immediately when an e-mail is received, and thus can be regarded as a terminal for real-time communication.

  The monitoring terminal 7 is not limited to those possessed or owned by a person related to the mobile phone 2, but may be an emergency notification receiving terminal such as a police station or a security company.

  In the above, the case where an emergency notification is given to the monitoring terminal 7 via the management center device 5 has been shown, but when the mobile phone 2 makes an emergency notification, the telephone number or mail address assigned to the monitoring terminal 7 is directly sent or sent. You may make it do.

  The first embodiment is characterized in that an emergency notification is transmitted when the mobile phone 2 is predetermined, and the configuration for transferring the emergency notification transmitted by the mobile phone 2 to the monitoring terminal 7 is any existing one. A transfer method may be applied.

  FIG. 3 is a block diagram illustrating an internal configuration of the mobile phone 2 according to the first embodiment. In FIG. 3, the cellular phone 2 includes a cellular phone antenna 10, a telephone radio unit 11, a GPS antenna 12, a GPS receiving unit 13, a control unit 14, a storage unit 15, a voice processing unit 16, a speaker 17, a microphone 18, and a key operation unit. 19 and a display unit 20.

  The mobile phone antenna 10 captures and radiates mobile phone radio signals (signaling signals and call signals). The telephone radio unit 11 demodulates a radio signal captured by the mobile phone antenna 10 or modulates a transmission signal and gives it to the mobile phone antenna 10. The cellular phone antenna 10 and the telephone radio unit 11 are the same as the existing ones. In the case of the first embodiment, the mobile phone system such as the analog system and the digital system is not limited, and the mobile phone antenna 10 and the telephone radio unit 11 have configurations and characteristics corresponding to the mobile phone system employed. It is.

  The GPS antenna 12 captures radio waves from the GPS artificial satellites and supplies them to the GPS receiving unit 13. The GPS receiving unit 13 processes radio signals from a plurality of GPS artificial satellites, and The position information is obtained.

  The control unit 14 includes a CPU and the like, and controls the entire mobile phone 2. The control unit 14 performs call control, voice processing during packet communication (packet assembly, disassembly, etc.). When the mobile phone 2 is of an analog system, the control unit 14 does not exist as if the voice signal between the telephone radio unit 11 and the voice processing unit 16 is transferred as it is. In the case of the first embodiment, the control unit 14 has not only control and processing related to the mobile phone function, but also emergency detection and emergency notification functions as described later.

  The storage unit 15 stores a program executed by the control unit 14 and is used as a working area as appropriate when the control unit 14 executes processing.

  The audio processing unit 16 performs predetermined processing (for example, digital / analog conversion, filtering, power amplification, etc.) on the audio signal or control sound signal from the control unit 14 and outputs the sound from the speaker 17 or is captured by the microphone 18. The audio signal is subjected to predetermined processing (for example, analog / digital conversion, filtering, power amplification, etc.) and is given to the control unit 14.

  The key operation unit 19 includes various keys, and gives a signal of a key operated by the user to the control unit 14. The display unit 20 displays a predetermined image under the control of the control unit 14. The key operation unit 19 and the display unit 20 have a man-machine interface function.

  FIG. 4 and FIG. 5 are functional block diagrams showing a configuration for realizing an emergency detection function and an emergency notification function in the mobile phone 2. The emergency detection and emergency notification functions are realized by software processing by the control unit 14 and signal exchange between the control unit 15 and the GPS reception unit 13 or the telephone radio unit 11, but are functional. Can be shown in the block diagrams of FIGS. Of course, the software processing part may be configured by a hardware logic circuit or the like.

  The cellular phone 2 has a position information receiving unit 30, an emergency state automatic detection unit 31, an emergency flag 32, a position information transfer control unit 33, and a position information transmission unit 34 with respect to emergency detection and emergency notification functions.

  The position information receiving unit 30 corresponds mainly to the GPS receiving unit 13 and acquires position information.

  The emergency automatic detection unit 31 calculates the moving speed of the mobile phone 2 based on the position information obtained by the position information receiving unit 30, and the occurrence of an emergency occurs based on whether the moving speed is equal to or higher than a threshold speed. Is detected. For example, the walking speed of elementary school students in the lower grades is about 3 km / h. Generally, a vehicle is used for taking away or kidnapping, and the traveling speed of the vehicle is about 40 to 60 km / h. In the first embodiment, an emergency situation occurs when the moving speed of the mobile phone 2 of a child (child walking to school) exceeds the speed when walking or running.

  Specifically, the emergency situation automatic detection unit 31 includes a movement amount calculation unit 40, a previous position storage unit 41, a speed calculation unit 42, a movement time management unit 43, and a determination / control unit 44, as shown in FIG.

  The previous position storage unit 41 stores position information at the time of the previous determination under the control of the determination / control unit 44. The movement amount calculation unit 40 calculates a movement amount (linear distance between two positions) from the position information obtained by the position information reception unit 30 and the previous position information stored in the previous position storage unit 41. is there.

  The movement time management unit 43 manages the time at the previous determination under the control of the determination / control unit 44, and at the time of the current determination, the speed calculation unit uses the time difference between the two determinations as the movement time. 42. The speed calculation unit 42 calculates the speed by dividing the movement amount (linear distance between two positions) obtained by the movement amount calculation unit 40 by the movement time.

  The control unit 14 performs various processes in parallel by time division. Since the control unit 14 performs communication with the base station as appropriate during standby, the period when the emergency detection and emergency notification functions are repeatedly executed is not necessarily constant even if a predetermined period is intended. . In other words, the determination time interval (movement time) is not a fixed time, and the movement time management unit 43 manages the movement time. It is also possible to set the interrupt priority in the processing routine of the emergency detection and emergency notification function to be the highest, and to set the interval (movement time) at the time of the determination to follow each other as a fixed time.

  Note that, by setting the movement time to about several seconds (for example, about 1 or 2 seconds), even if the straight line distance between the two positions is regarded as the movement amount, it is considered that the determination is not adversely affected. For example, when turning at an intersection, the straight line distance between two positions does not match the amount of movement, but even in such a case, if the movement time is set to be as short as several seconds, the movement amount at that time can be reduced. Even if approximated by a linear distance between two positions, the error is small and does not adversely affect the determination described later.

  Here, the map information may be built in, and the positional information at the time of the determination that is the same may be mapped to the map information, the movement route may be specified, and the movement amount may be accurately detected.

  Further, if the determination is repeated accurately at a predetermined cycle, the movement amount may be used as it is as speed information.

  The determination / control unit 44 compares the speed obtained by the speed calculation unit 42 with a threshold (for example, 10 km / h; may be variably settable), and determines the occurrence of an emergency according to the comparison result. Is. The determination / control unit 44 may perform determination based on one comparison result. That is, when a comparison result that the speed obtained by the speed calculation unit 42 is equal to or greater than the threshold value is obtained, it may be immediately recognized that an emergency has occurred. Further, the determination / control unit 44 may determine from a plurality of comparison results. For example, three out of the latest five comparison results may be recognized as an occurrence of an emergency only when the comparison result indicates that the speed obtained by the speed calculation unit 42 is equal to or greater than a threshold value. When the determination / control unit 44 recognizes the occurrence of an emergency, the determination / control unit 44 sets the emergency flag 32 or notifies the position information transfer control unit 33 of the occurrence of the emergency.

  Further, the determination / control unit 44 stores the current position information in the previous position storage unit 41 or the current time of determination in the travel time management unit 43 for the next determination. .

  Note that the emergency automatic detection unit 31 may not execute the detection process after recognizing (detecting) the occurrence of the emergency, and continuously performs the detection operation even after the detection. May be. Further, after the position information history section is built in and the occurrence of an emergency is recognized (detected), the position information may be recorded together with the time information at a predetermined period (for example, 1 minute).

  The emergency flag 32 indicates that the set state indicates the occurrence of an emergency. Therefore, initially, the emergency flag 32 is in a reset state. It is preferable that the emergency flag 32 in the set state cannot be reset even when the power is turned off or the power is turned off. Returning the emergency flag 32 in the set state to the reset state is permitted, for example, on the condition that key operations in a predetermined order with respect to the key operation unit 19 have been performed. It is preferable to include the input operation. Even if a power switch (not shown) is turned off, it is preferable that the control unit 14 does not execute the power off operation when the emergency flag 32 is set.

  When the emergency automatic detection unit 31 automatically detects the occurrence of an emergency, the location information transfer control unit 33 uses the automatic transmission function of the location information transmission unit 34 to make an emergency notification including the occurrence of the emergency and the current location information. (Emergency occurrence notification) is transmitted. In addition, the position information transfer control unit 33 subsequently confirms that the emergency flag 32 is set, and the moving position including the current position information at a predetermined cycle by the automatic transmission function of the position information transmission unit 34. Send a notification.

  In the case of the first embodiment, a location inquiry can be made to the mobile phone 2 from the monitoring terminal 7 or the management center device 5, and the location information transfer control unit 33 responds to the emergency flag 32 to the inquiry. Is confirmed to be set, and the current position notification including the current position information is transmitted from the position information transmitting unit 34.

  Various notifications such as the emergency notification (emergency occurrence notification), the movement position notification, and the current position notification described above may take a signal form corresponding to a channel used for communication. For example, if voice communication using a call channel is used, various notifications are made using synthesized voice signals. For example, if data communication using a call channel or data communication using a standby channel is used, various notifications are transmitted as data.

  As described above, the position information transmission unit 34 transmits various notifications under the control of the position information transfer control unit 33. If a call channel is used for sending notifications, a call channel establishment operation is also performed as appropriate. Here, in the repeated transmission of the movement position notification after the emergency notification (emergency occurrence notification), the call channel established at the time of the emergency notification may be used as it is.

  Whether or not to detect the emergency situation and the emergency notification function in the mobile phone 2 as described above may be switched by operating the emergency notification mode key in the key operation unit 19. Also, such a switching function is not provided, and the emergency detection function and the emergency notification function are valid only during the preset time zone (for example, the setting is based on a signal from the management center device 5). You may make it.

  As described above, in the mobile phone 2 and the emergency notification system 1 of the first embodiment, when the speed of the mobile phone 2 is significantly faster than the walking speed at the time of attending school, it is automatically detected as the occurrence of an emergency. Therefore, it is possible to make an emergency notification almost in real time when an emergency occurs without using an emergency notification operation as a condition.

(B) Second Embodiment Next, a second embodiment of the mobile communication terminal and the emergency notification system according to the present invention will be described in detail with reference to the drawings.
