In the following description, in order to simplify the description, the owner of the first mobile phone 1 may be referred to as a protected person, and the owner of the second mobile phone 2 may be referred to as a guardian.

  The first mobile phone 1 calculates a moving distance per predetermined time. When the movement distance per predetermined time is out of the range determined according to the predetermined time, the notification information is transmitted to the second mobile phone 2. The range determined according to the predetermined time is a range of distance that the protected person is supposed to move by himself / herself during the predetermined time. The movement of the guardian himself / herself may include moving on a vehicle that can be driven by himself / herself, such as a bicycle, in addition to walking and running. In the following description, the movement distance per predetermined time may be simply referred to as “movement distance”. In the following description, a range determined according to a predetermined time may be referred to as a “distance range”.

  The notification information includes a comparison result between the moving distance and the distance range. The comparison result between the movement distance and the distance range includes at least information indicating whether the movement distance exceeds or falls below the distance range. When the second mobile phone 2 receives the notification information, the second mobile phone 2 performs notification to the guardian. As a result, the guardian can know at an early stage that the moving distance of the first mobile phone 1 may be abnormal in the guardian.

  For example, if it is reported that the distance traveled exceeds the distance range at a time when the guardian should not be moving on the vehicle, the guardian has been involved in a crime such as kidnapping. , You can know that you may have missed the school section. For example, if it is reported that the distance traveled is less than the distance range during the time that should be in the middle of going to and from school, the guardian may be unable to move due to an accident or poor physical condition. You can know that there is.

  Thus, the function of performing notification when the moving distance is out of the distance range is useful as a security function.

  The distance table 46 is a table for specifying a distance range corresponding to the person to be protected. The distance that can be moved in a predetermined time varies depending on the physical ability. Therefore, the distance table 46 includes a plurality of distance conditions, and each distance range is associated with information for specifying physical ability. The information for specifying physical ability is, for example, age, school year, gender, residential area, height, stride, or a combination thereof. The distance range included in the distance table 46 may have only the upper limit of the distance range in which the protected person is assumed to move by himself / herself during a predetermined time. The distance table 46 may be configured to hold a distance range every a plurality of predetermined times.

  The control unit 100 executes processing based on various programs stored in the storage unit 40. The control unit 100 includes, for example, a microprocessor unit (MPU: Micro Processing Unit). The control unit 100 sequentially reads instruction codes from a program stored in the storage unit 40, and executes various processes of the first mobile phone 1 according to procedures instructed by the read instruction codes. That is, the control unit 100 performs various processes of the first mobile phone 1 in an appropriate procedure according to the operation of the operation unit 14 and the program stored in the storage unit 40 of the first mobile phone 1. In addition, operations of the display unit 15, the camera 16, the communication unit 17, the acceleration sensor 18, the sound processing unit 20, and the like are controlled.

  As illustrated in FIG. 2, the control unit 100 includes a positioning unit 110, a calculation unit 120, a counting unit 130, and a determination unit 140.

  The positioning unit 110 performs positioning based on the radio signal received by the communication unit 17 from the GPS satellite. The positioning unit 110 stores the position information obtained by the positioning process in the data storage area 41 in association with the time at which the positioning process was performed.

  The positioning unit 110 may perform positioning by another method instead of or in addition to the method using the radio signal received by the communication unit 17 from the GPS satellite. For example, the positioning unit 110 may perform positioning based on identification information of one or a plurality of base stations or access points from which the communication unit 17 is receiving radio. In this case, the positioning unit 110 may perform positioning by comparing previously registered information with identification information, or may inquire about the position corresponding to the identification information via the communication unit 17. The positioning unit 110 may perform positioning by further using the strength of radio waves received from the base station or access point.

  The calculation unit 120 calculates the movement distance based on the result of the positioning process performed by the positioning unit 110. For example, the latest position information obtained by the positioning process of the positioning unit 110 and the position information obtained a predetermined time before the time when the latest position information was obtained are acquired from the data storage area 41. Then, the calculation unit 120 calculates the distance between the positions indicated by the two pieces of position information as the movement distance.

  The calculation unit 120 may calculate the movement distance based on the result of the positioning process three times or more. For example, in addition to the latest position information and the position information obtained before a predetermined time before the time when the latest position information is obtained, the calculation unit 120 adds all the position information obtained during that time to the data storage area. 41. Then, the calculation unit 120 connects the positions indicated by the obtained position information in the order in which the position information is obtained, and calculates the total length of the connected lines as the movement distance. As described above, by calculating the movement distance based on the result of the positioning process three times or more, even when the guardian is not moving linearly, the calculation accuracy of the movement distance can be improved.

  The calculation unit 120 may calculate the travel distance in consideration of a route that can be passed. For example, the calculation unit 120 acquires map data including the position indicated by the acquired two position information, and finds the shortest route that can be connected to the position indicated by the two acquired position information. Then, the calculation unit 120 calculates the length of the found route as the movement distance. The map data may be stored in the storage unit 40 or may be acquired by communication of the communication unit 17. The calculation unit 120 may find a passable path using the result of the positioning process three times or more. When the protected person is a child and a route to be passed is determined in advance as in a school road, the calculation unit 120 may find a route so as to include as many routes as possible. . Thus, the calculation accuracy of the movement distance can be further improved by calculating the movement distance in consideration of the route that can be passed.

  The method of calculating the movement distance by the calculation unit 120 is not limited to this. For example, the calculation unit 120 may calculate the movement distance by integrating the amount of displacement calculated based on a change in acceleration detected by the acceleration sensor 18. Alternatively, the calculation unit 120 may calculate the movement distance based on the number of steps counted by the counting unit 130.

  The counting unit 130 counts the number of steps of the protected person based on the change in acceleration detected by the acceleration sensor 18. The counting unit 130 stores the number of steps in the data storage area 41. The counting unit 130 may count the number of steps by other methods. For example, the counting unit 130 may be a pendulum pedometer.

  The determination unit 140 determines whether or not the movement distance calculated by the calculation unit 120 is out of the distance range. The determination unit 140 specifies a distance range used for comparison with the moving distance from among a plurality of candidates included in the distance table 46. As already described, the distance range is associated with information for specifying physical ability. Therefore, the determination unit 140 collects information indicating the physical ability of the protected person. For example, when age or school year is included in the information for specifying physical ability, the determination unit 140 calculates the age or school year of the guardian based on the date of birth included in the guardian information 43 To do. If the information for specifying the physical ability includes gender, the determination unit 140 acquires the gender included in the guardian information 43. When the residence area is included in the information for specifying the physical ability, the determination unit 140 acquires the residence area of the protected person based on the result of the positioning process by the positioning unit 110 or preset information. . By using the information thus collected, the distance range corresponding to the physical ability of the person to be protected can be acquired from the distance table 46.

  The determination unit 140 may determine that the movement distance has deviated from the distance range when the movement distance exceeding or below the distance range is continuously calculated by the calculation unit 120 more than a predetermined number of times. By comprising in this way, it can suppress that alerting | reporting information is transmitted when a movement distance only deviates from the distance range temporarily for some reason. Alternatively, the determination unit 140 may determine that the moving distance is out of the distance range only when the moving distance exceeds the upper limit of the distance range. By comprising in this way, it can suppress that alerting | reporting is made when the movement distance is less than the distance range for a normal reason like the case where the to-be-protected person waits for a signal.

Further, the communication unit 36 may receive a radio signal in a predetermined frequency band from a GPS satellite, perform demodulation processing on the received radio signal, and send the processed signal to the control unit 200.

  The audio processing unit 50 performs processing of an audio signal input to the microphone 31 and an audio signal output from the speaker 32 and the receiver 33. That is, the audio processing unit 50 amplifies the audio input from the microphone 31 and performs analog-digital conversion, and then performs signal processing such as encoding to convert it into digital audio data and then to the control unit 200. Send it out. The audio processing unit 50 performs processing such as decoding, digital-analog conversion, and amplification of audio data sent from the control unit 200, converts the data into analog audio signals, and outputs the analog audio signals to the speaker 32 and the receiver 33.

  The storage unit 70 stores various programs and various data used for processing in the control unit 200 such as an operating system program and an application program. For example, the storage unit 70 includes a task for operating an application program for controlling the operation of the display unit 35, a task for operating an application program for controlling the operation of the communication unit 36, and an application program for controlling the operation of the audio processing unit 50.

Voice files such as dial tone and ring tone, temporary data used in the process based on the program, and the like are stored.

  In the present embodiment, destination information 71 is stored in the storage unit 70. The transmission destination information 71 includes transmission destination data of the first mobile phone 1 to which the second mobile phone 2 transmits various information. The destination data includes, for example, a mail address, a telephone number, etc. of the first mobile phone 1.

  The control unit 200 executes processing based on various programs stored in the storage unit 70. The control unit 200 is composed of, for example, a microprocessor unit, sequentially reads instruction codes from a program stored in the storage unit 70, and performs various processes of the second mobile phone 2 in accordance with procedures instructed by the read instruction codes. Run. That is, the control unit 200 displays the display unit 35, so that various processes of the second mobile phone 2 are executed in an appropriate procedure according to the operation of the operation unit 34 and the program stored in the storage unit 70. Controls the operations of the communication unit 36, the voice processing unit 50, and the like.

  The control unit 200 performs various controls for notifying the guardian that the moving distance of the first mobile phone 1 is out of the distance range. For example, the control unit 200 displays a screen or the like based on the notification information received from the first mobile phone 1 on the display unit 35 and controls the voice processing unit 50 to output a notification sound or the like from the speaker 32 or the like. The control unit 200 may perform notification in either display of a screen or the like or output of notification sound or the like.

  So far, the basic configuration of the communication system 10 according to the present embodiment has been described. Hereinafter, an example of control when it is detected that the moving distance of the first mobile phone 1 is out of the distance range in the communication system 10 will be described with reference to FIGS. 5 to 7. FIG. 5 is a diagram illustrating an example of processing of the communication system 10 when it is detected that the moving distance of the first mobile phone 1 is out of the distance range. FIG. 6 is a diagram illustrating an example of a screen displayed by the second mobile phone 2 that has received the notification information. FIG. 7 is a diagram illustrating an example of a screen displayed by the second mobile phone 2 that has received the position information.

  As shown in FIG. 5, the first mobile phone 1 periodically executes a positioning process at the positioning unit 110 at a predetermined time or at an interval shorter than that (step S1). The first mobile phone 1 calculates the movement distance by the calculation unit 120 based on the position information obtained by executing the positioning process (step S2). In the first mobile phone 1, the determination unit 140 determines whether the moving distance is out of the distance range. When it is detected that the moving distance is out of the distance range (step S3), the first mobile phone 1 determines whether the notification information should be transmitted to the second mobile phone 2. For example, the first mobile phone 1 should transmit the notification information to the second mobile phone 2 when the last measured position is not included in any of the areas indicated by the area conditions of the notification condition information 44. judge. Alternatively, in the first mobile phone 1, even when the position measured last is included in any area indicated by the area condition of the notification condition information 44, the current time is not included in the time zone corresponding to the area. It is determined that the notification information should be transmitted to the second mobile phone 2. When it is determined that the notification information should be transmitted to the second mobile phone 2, the first mobile phone 1 transmits the notification information including information indicating the comparison result between the moving distance and the distance range to the second mobile phone 2. (Step S4). The notification information further includes, for example, the position information obtained last, the moving distance, the current time, and the like.

  When the first mobile phone 1 detects that the moving distance is out of the distance range, the first mobile phone 1 changes the position transmission processing mode. The position transmission process is a process for causing the positioning unit 110 to perform positioning and transmitting the obtained position information to the second mobile phone 2. The positioning for the position transmission process may double as the positioning for calculating the movement distance. The mode change may be such that position transmission processing that has not been executed is periodically executed. The mode change may be to change the transmission interval at which the position transmission process is executed. By shortening the transmission interval, the guardian can grasp the situation of the guardian in detail. By increasing the transmission interval, power consumption can be suppressed and the operating time of the first mobile phone 1 can be extended. The first mobile phone 1 may transmit other information together when transmitting the position information in the position transmission process. Other information includes, for example, the current time, the remaining battery level, and the like. In this case, the mode change may be to increase or decrease the information transmitted to the second mobile phone 2.

  The first mobile phone 1 may be configured such that a guardian can arbitrarily set a mode before and after a detection that the moving distance is out of the distance range. The first mobile phone 1 may be configured to change the mode change method when the moving distance exceeds the upper limit of the distance range and when the moving distance falls below the lower limit. When the first mobile phone 1 detects that the movement distance of the first mobile phone 1 is out of the distance range when receiving a request transmitted from the second mobile phone 2 in response to the operation of the guardian, It may be configured to return the changed mode to the original mode.

  When the second mobile phone 2 receives the notification information from the first mobile phone 1, it performs notification based on the notification information (step S5). For example, the second mobile phone 2 acquires map data corresponding to the position information included in the notification information, displays the screen 300 shown in FIG. 6 on the display unit 35, and outputs a notification sound from the speaker 32 or the like. The screen 300 has a message part 301 and a map part 302. Message unit 301 displays a message for notifying that the moving distance of first mobile phone 1 is out of the distance range. The map unit 302 displays map data corresponding to the position information included in the notification information. In the example shown in FIG. 6, the message unit 301 displays a message “The moving distance of the first mobile phone has gone out of the distance range.” In the example illustrated in FIG. 6, the map unit 302 displays map data 400 including the mark P1 corresponding to the position indicated by the position information included in the notification information.

  Thereafter, when the transmission interval elapses after the notification information is transmitted to the second mobile phone 2 in step S4, the first mobile phone 1 executes the positioning process in the positioning unit 110 for the position transmission process (step S6). ). The first mobile phone 1 transmits the position information obtained by the positioning process to the second mobile phone 2 (step S7).

  When the second mobile phone 2 receives the position information from the first mobile phone 1, it performs notification based on the position information (step S8). For example, the second mobile phone 2 acquires map data including the position information included in the notification information transmitted in step S4 and the respective positions indicated by the position information transmitted in step S7, as shown in FIG. The screen 300 is updated. In the example shown in FIG. 7, the display of the message part 301 on the screen 300 is left as it is, and the map data 401 is displayed on the map part 302. Map data 401 includes mark P1 corresponding to the position indicated by the position information included in the notification information and mark P2 corresponding to the position indicated by the position information transmitted in step S7. That is, the map data 401 indicates the current position (mark P2) and the movement locus (marks P1, P2) of the first mobile phone 1. Thereafter, the communication system 10 repeats the processing from step S6 to step S8 at every transmission interval.

  Next, with reference to FIG. 8, an example of a processing procedure for the first mobile phone 1 to detect that the moving distance is out of the distance range will be described. FIG. 8 is a flowchart illustrating an example of a processing procedure for detecting that the moving distance of the first mobile phone 1 is out of the distance range. FIG. 8 shows a processing procedure when the positioning process is executed every predetermined time. The processing procedure shown in FIG. 8 is repeatedly executed when the position transmission processing mode is the initial mode.

  As shown in FIG. 8, the control part 100 sets predetermined time as step S101, and monitors progress of predetermined time using a timer etc. As shown in FIG. In step S102, the control unit 100 determines whether a predetermined time has elapsed. When it is determined in step S102 that the predetermined time has not elapsed (No), the control unit 100 returns to step S102 and executes the subsequent steps. If the control unit 100 determines in step S102 that the predetermined time has elapsed (Yes), the control unit 100 proceeds to step S103.

  The control part 100 performs a positioning process by the positioning part 110 as step S103. In step S <b> 104, the control unit 100 calculates the movement distance by the calculation unit 120. In step S105, the control unit 100 determines whether or not the movement distance obtained by the calculation unit 120 is out of the distance range. When the control unit 100 determines in step S105 that the movement distance is not out of the distance range (No), the control unit 100 ends the processing procedure. If the control unit 100 determines in step S105 that the movement distance is out of the distance range (Yes), the control unit 100 proceeds to step S106.

  Based on the notification condition information 44, the control unit 100 determines whether or not the notification information should be transmitted to the second mobile phone 2 in step S106. When the control unit 100 determines in step S106 that the notification information should not be transmitted to the second mobile phone 2 (No), the process procedure ends. If the control unit 100 determines in step S106 that the notification information should be transmitted to the second mobile phone 2 (Yes), the control unit 100 proceeds to step S107.

  The control unit 100 transmits the notification information to the second mobile phone 2 as step S107. Then, in step S108, the control unit 100 changes the position transmission processing mode and ends the processing procedure.

  Next, an example of a procedure of position transmission processing when the mode is changed will be described with reference to FIG. FIG. 9 is a flowchart illustrating an example of a processing procedure of the position transmission process when the mode is changed. The processing procedure shown in FIG. 9 is repeatedly executed after the position transmission processing mode is changed in step S108 shown in FIG.

  As shown in FIG. 9, the control unit 100 sets a transmission interval as step S201, and monitors the elapse of the transmission interval using a timer or the like. In step S202, the control unit 100 determines whether the transmission interval has elapsed. If the control unit 100 determines in step S202 that the transmission interval has not elapsed (No), the control unit 100 proceeds to step S205. If the control unit 100 determines in step S202 that the transmission interval has elapsed (Yes), the control unit 100 proceeds to step S203.

  The control part 100 performs a positioning process by the positioning part 110 as step S203. And the control part 100 transmits the positional infomation obtained by the positioning process to the 2nd mobile telephone 2 as step S204. Thereafter, the control unit 100 ends this processing procedure.

  In step S205, the control unit 100 determines whether a mode return request has occurred. The mode return request is a request for returning the position transmission processing mode to the initial mode. The mode return request is generated, for example, when an instruction based on a predetermined operation of the guardian on the second mobile phone 2 is transmitted from the second mobile phone 2 to the first mobile phone 1. After changing the position transmission processing mode, first mobile phone 1 periodically determines whether or not a situation in which notification information should be transmitted continues based on notification condition information 44 and transmits the notification information. A mode return request may be generated when it is determined that the power situation has not continued.

  If the control unit 100 determines in step S205 that no mode return request has been generated (No), the control unit 100 returns to step S202 and executes the subsequent steps. If the control unit 100 determines in step S205 that a mode return request has occurred (Yes), the control unit 100 proceeds to step S206. In step S206, the control unit 100 returns the position transmission processing mode to the initial mode, and ends this processing procedure.

  Next, an example of a processing procedure in the case where the second mobile phone 2 notifies that the moving distance of the first mobile phone 1 is out of the distance range will be described with reference to FIG. FIG. 10 is a flowchart illustrating an example of a processing procedure when the second mobile phone 2 notifies that the moving distance of the first mobile phone 1 is out of the distance range. The processing procedure shown in FIG. 10 is repeatedly executed.

  As illustrated in FIG. 10, the control unit 200 determines whether or not notification information is received from the first mobile phone 1 in step S301. When it is determined that the notification information is not received (No) in Step S301, the control unit 200 proceeds to Step S304. When determining that the notification information is received (Yes) in step S301, the control unit 200 stores the notification information in the storage unit 70, and proceeds to step S302.

  In step S302, the control unit 200 acquires map data including the position indicated by the position information included in the notification information. The control unit 200 performs notification based on the notification information received from the first mobile phone 1 as step S303. Thereafter, the control unit 200 proceeds to step S304.

  The control unit 200 determines whether or not position information has been received from the first mobile phone 1 in step S304. If the control unit 200 determines in step S304 that position information has not been received (No), the control unit 200 proceeds to step S307. When determining that the position information has been received (Yes) in Step S304, the control unit 200 stores the received position information in the storage unit 70 in association with the notification information received in Step S301, and proceeds to Step S305. .

  In step S305, the control unit 200 acquires map data including the position indicated by the position information. Control part 200 performs information based on position information as Step S306.

  In step S307, the control unit 200 determines whether or not the operation unit 34 has undergone a mode return operation for returning the position transmission processing mode in the first mobile phone 1 to the initial mode. If the control unit 200 determines in step S307 that there has been no operation for mode return (No), the control unit 200 ends this processing procedure. If the control unit 200 determines in step S307 that a mode return operation has been performed (Yes), the control unit 200 proceeds to step S308.

  In step S308, the control unit 200 transmits an instruction to return the mode of the position transmission process in the first mobile phone 1 to the first mobile phone 1, and ends this processing procedure.

  As described above, the first mobile phone 1 transmits the notification information to the second mobile phone 2 when detecting that the moving distance is out of the distance range. For this reason, the guardian can quickly know when the movement state of the guardian is not a normal state. As a result, the guardian can quickly respond to the removal of the guardian, encountering an accident, poor physical condition, and the like.

  As described above, when the first mobile phone 1 detects that the moving distance is out of the distance range, the first mobile phone 1 changes the mode of the position transmission process. For this reason, the 1st mobile telephone 1 can set appropriately the space | interval etc. which transmit position information to the 2nd mobile telephone 2, etc., when the movement state of a to-be-protected person is not a normal state.

  As described above, after detecting that the moving distance is out of the distance range, the first mobile phone 1 periodically performs a positioning process and transmits position information to the second mobile phone 2. For this reason, the guardian can regularly know the latest information regarding the location of the guardian.

  The first mobile phone 1 may be configured to change the position transmission processing mode in response to a request transmitted from the second mobile phone 2.

  Referring to FIG. 11, when the communication system 10 detects that the moving distance is out of the distance range, the first mobile phone 1 performs position transmission processing in response to a request transmitted from the second mobile phone 2. An example of control when changing the mode will be described. FIG. 11 is a diagram illustrating another example of processing of the communication system when it is detected that the moving distance of the first mobile phone is out of the distance range.

  As shown in FIG. 11, the first mobile phone 1 periodically executes a positioning process in the positioning unit 110 at a predetermined time or at an interval shorter than that (step S11). The first mobile phone 1 calculates the movement distance by the calculation unit 120 based on the position information obtained by executing the positioning process (step S12). In the first mobile phone 1, the determination unit 140 determines whether the moving distance is out of the distance range. When it is detected that the moving distance is out of the distance range (step S13), the first mobile phone 1 determines whether the notification information should be transmitted to the second mobile phone 2. When it is determined that the notification information should be transmitted to the second mobile phone 2, the first mobile phone 1 transmits the notification information including information indicating the comparison result between the moving distance and the distance range to the second mobile phone 2. (Step S14).

  When the second mobile phone 2 receives the notification information from the first mobile phone 1, it performs notification based on the notification information (step S15). At this time, it is assumed that the guardian has performed a predetermined operation for requesting periodic notification of the position of the guardian. In that case, the second mobile phone 2 transmits a periodic transmission request to the first mobile phone 1 (step S16). When the second mobile phone 2 performs notification based on the notification information, the second mobile phone 2 may inquire of the guardian whether or not to periodically notify the position of the person to be protected.

  When the first mobile phone 1 receives the periodic transmission request from the second mobile phone 2, the first mobile phone 1 sets the position transmission processing mode so that the position information is periodically transmitted. Thereafter, when the first transmission interval elapses after changing the position transmission processing mode, the first mobile phone 1 executes the positioning processing in the positioning unit 110 (step S17). The first mobile phone 1 transmits the position information obtained by the positioning process to the second mobile phone 2 (step S18).

  When the second mobile phone 2 receives the position information from the first mobile phone 1, it performs notification based on the position information (step S19). At this time, it is assumed that the guardian performs a predetermined operation for changing the transmission interval of the position transmission process. In that case, the second mobile phone 2 transmits a change request for changing the transmission interval to the first mobile phone 1 (step S20).

  When receiving the change request from the second mobile phone 2, the first mobile phone 1 changes the first transmission interval to the second transmission interval based on the change request (step S21). Thereafter, when the second transmission interval elapses after the first mobile phone 1 transmits the position information to the second mobile phone 2 in step S18, the positioning unit 110 executes a positioning process (step S22). The first mobile phone 1 transmits the position information obtained by the positioning process to the second mobile phone 2 (step S23).

  When the second mobile phone 2 receives the position information from the first mobile phone 1, the second mobile phone 2 performs notification based on the position information (step S24). Thereafter, the communication system 10 repeats Step S22 to Step S24 every second transmission interval.

  Next, referring to FIG. 12, when it is detected that the moving distance of the first mobile phone 1 is out of the distance range, the first mobile phone 1 changes the mode in response to a request from the second mobile phone 2. An example of the processing procedure to be changed will be described. FIG. 12 is a flowchart showing control in which the first mobile phone 1 changes the mode in response to a request from the second mobile phone 2. The processing procedure shown in FIG. 12 is repeatedly executed when the position transmission processing mode is the initial mode.

  As shown in FIG. 12, the control unit 100 sets a predetermined time in step S401, and monitors the elapse of the predetermined time using a timer or the like. In step S402, the control unit 100 determines whether a predetermined time has elapsed. When it is determined in step S402 that the predetermined time has not elapsed (No), the control unit 100 returns to step S402 and executes the subsequent steps. If the control unit 100 determines in step S402 that the predetermined time has elapsed (Yes), the control unit 100 proceeds to step S403.

  The control part 100 performs a positioning process in the positioning part 110 as step S403. In step S404, the control unit 100 uses the calculation unit 120 to calculate the movement distance. In step S405, the control unit 100 determines whether or not the movement distance obtained by the calculation unit 120 is out of the distance range. If the control unit 100 determines in step S405 that the movement distance is not out of the distance range (No), the control unit 100 ends this processing procedure. If the control unit 100 determines in step S405 that the movement distance is out of the distance range (Yes), the control unit 100 proceeds to step S406.

  Based on the notification condition information 44, the control unit 100 determines whether or not the notification information should be transmitted to the second mobile phone 2 in step S406. When the control unit 100 determines in step S406 that the notification information should not be transmitted to the second mobile phone 2 (No), the process procedure ends. When the control unit 100 determines in step S406 that the notification information should be transmitted to the second mobile phone 2 (Yes), the control unit 100 proceeds to step S407.

  In step S407, the control unit 100 transmits notification information indicating that the moving distance of the first mobile phone 1 is out of the distance range to the second mobile phone 2.

  In step S408, the control unit 100 determines whether a periodic transmission request has been received from the second mobile phone 2. If the control unit 100 determines in step S408 that the periodic transmission request has not been received from the second mobile phone 2 (No), the processing procedure ends. If the control unit 100 determines in step S408 that a periodic transmission request has been received from the second mobile phone 2 (Yes), the control unit 100 proceeds to step S409. In step S409, the control unit 100 changes the position transmission processing mode and ends the processing procedure.

  Next, referring to FIG. 13, when the control unit 100 changes the position positioning processing mode in response to a periodic transmission request from the second mobile phone 2, the location information is notified to the second mobile phone 2. An example of the processing procedure in this case will be described. FIG. 13 is a flowchart showing an example of the procedure of the position transmission process when the first mobile phone 1 changes the mode in response to a request from the second mobile phone 2. The processing procedure shown in FIG. 13 is repeatedly executed after the position transmission processing mode is changed in step S409 shown in FIG.

  As shown in FIG. 13, the control unit 100 sets a transmission interval and monitors the progress of the transmission interval using a timer or the like as step S501. In step S502, the control unit 100 determines whether the transmission interval has elapsed. If the control unit 100 determines in step S502 that the transmission interval has elapsed (Yes), the control unit 100 proceeds to step S503.

  The control part 100 performs a positioning process in the positioning part 110 as step S503. And control part 100 transmits the position information obtained by positioning processing to the 2nd mobile phone 2 as Step S504. Thereafter, the control unit 100 ends this processing procedure.

  If the control unit 100 determines in step S502 that the transmission interval has not elapsed (No), the control unit 100 proceeds to step S505. In step S505, the control unit 100 determines whether a change request has been received from the second mobile phone 2. If the control unit 100 determines in step S505 that a change request has not been received (No), the control unit 100 proceeds to step S507.

  If the control unit 100 determines in step S505 that a change request has been received (Yes), the control unit 100 proceeds to step S506. In step S506, the control unit 100 changes the transmission interval based on the received change request.

  As step S507, the control unit 100 determines whether or not the above-described mode return request has occurred. If the control unit 100 determines in step S507 that a mode return request has not occurred (No), the control unit 100 returns to step S502 and executes the subsequent steps. If the control unit 100 determines in step S507 that a mode return request has occurred (Yes), the control unit 100 proceeds to step S508. In step S508, the control unit 100 returns the position transmission processing mode to the initial mode, and ends this processing procedure.

  Next, referring to FIG. 14, processing when second mobile phone 2 notifies that the moving distance of first mobile phone 1 is out of the distance range and requests periodic notification from first mobile phone 1. An example of the procedure will be described. FIG. 14 is a flowchart showing another example of the processing procedure when the second mobile phone 2 notifies that the moving distance of the first mobile phone 1 is out of the distance range.

  As shown in FIG. 14, the control unit 200 determines whether or not notification information has been received from the first mobile phone 1 in step S601. If the control unit 200 determines in step S601 that the broadcast information has not been received (No), the control unit 200 proceeds to step S606. When it is determined that the notification information is received (Yes) in step S601, the control unit 200 stores the notification information in the storage unit 70, and proceeds to step S602.

  In step S602, the control unit 200 acquires map data including the position indicated by the position information included in the notification information. In step S603, the control unit 200 performs notification based on the notification information received from the first mobile phone 1. Thereafter, the control unit 200 proceeds to step S604.

  In step S604, the control unit 200 determines whether or not a regular notification operation has been performed on the operation unit 34. If the control unit 200 determines in step S604 that there is no regular notification operation (No), the control unit 200 proceeds to step S606. If the control unit 200 determines in step S604 that a regular notification operation has been performed (Yes), the control unit 200 proceeds to step S605. The control unit 200 transmits a periodic transmission request to the first mobile phone 1 as step S605.

  In step S606, the control unit 200 determines whether position information has been received from the first mobile phone 1. If the control unit 200 determines in step S606 that position information has not been received (No), the control unit 200 proceeds to step S609. When determining that the position information has been received (Yes) in step S606, the control unit 200 stores the received position information in the storage unit 70 in association with the notification information received in step S601, and proceeds to step S607. .

  In step S607, the control unit 200 acquires map data including the position indicated by the position information. Control part 200 performs information based on position information as Step S608.

  In step S609, the control unit 200 determines whether or not an operation for changing the transmission interval has been performed on the operation unit 34. If the control unit 200 determines in step S609 that the transmission interval change operation has not been performed (No), the control unit 200 proceeds to step S611. If it is determined in step S609 that the transmission interval change operation has been performed (Yes), the control unit 200 stores the changed transmission interval in the storage unit 70, and proceeds to step S610. In step S610, the control unit 200 transmits a request for changing the transmission interval to the changed transmission interval to the first mobile phone 1.

  In step S611, the control unit 200 determines whether or not the operation unit 34 has undergone a mode return operation for returning the position transmission processing mode in the first mobile phone 1 to the initial mode. If the control unit 200 determines in step S611 that a mode return operation has not been detected (No), the process procedure ends. If the control unit 200 determines in step S611 that a mode return operation has been performed (Yes), the control unit 200 proceeds to step S612.

  In step S612, the control unit 200 transmits an instruction to return the mode of the position transmission process in the first mobile phone 1 to the first mobile phone 1, and ends this processing procedure.

  As described above, when the first mobile phone 1 detects that the moving distance is out of the distance range, the first mobile phone 1 changes the position transmission processing mode in response to a request from the second mobile phone 2. Therefore, in response to a request from the guardian, the first mobile phone 1 determines whether or not to periodically transmit the position information to the second mobile phone 2 when the movement state of the guardian is not a normal state. Can be determined appropriately.

  As described above, the first mobile phone 1 changes the transmission interval of the position information based on the change request from the second mobile phone 2. For example, when changing the transmission interval to be shorter, the first mobile phone 1 transmits the position information to the second mobile phone 2 more frequently. For this reason, the guardian can grasp the movement situation of the guardian in detail. Or when the 1st mobile telephone 1 changes a transmission interval long, power consumption is suppressed and operating time is extended. For this reason, the guardian can grasp the situation of the guardian for a long time.

  Embodiment which this application discloses can be changed in the range which does not deviate from the summary and range of invention. Furthermore, the embodiment disclosed in the present application and its modifications can be combined as appropriate. For example, the above embodiment may be modified as follows.

  In the above embodiment, an example is shown in which the distance range to be compared with the moving distance is selected from a plurality of predetermined candidates. However, the method of acquiring the distance range is not limited to this. For example, the distance range may be dynamically calculated based on the number of steps counted by the counting unit 130 within a predetermined time. In this case, for example, a value obtained by multiplying the minimum value of the step length of the protected person by the number of steps becomes the lower limit of the distance range, and a value obtained by multiplying the maximum value of the step length of the protected person by the number of steps becomes the upper limit of the distance range. The minimum value of the stride is a stride when walking slowly, for example. The maximum value of the stride is, for example, a stride when running. For the minimum and maximum values of the stride length of the protected person, for example, the one corresponding to the information indicating the physical ability of the protected person is selected from a plurality of candidates associated with the information for specifying the physical ability Is obtained by

  Alternatively, the distance range may be calculated by setting a parameter in a function prepared in advance. The parameters are, for example, predetermined time, age, school year, sex, residential area, height, stride, and the like.

  The distance range may be preset by a guardian. The first mobile phone 1 has a geographical condition such as the magnitude of the gradient, a temporal condition such as a change in the number of passers by time, a condition depending on traffic conditions such as a narrow road, rain, wind, etc. The distance range may be changed in accordance with current conditions such as weather conditions.
