The control unit 500 can also be called a control device or a control circuit. Control unit 500 includes at least one processor to provide control and processing power to perform various functions, as described in further detail below. The above description of the processor included in the controller 200 of the electronic device 2 can also be applied to the processor included in the controller 500 .

In this example, the control unit 500 includes a CPU 501 and a storage unit 502 . The storage unit 502 includes non-temporary recording media readable by the CPU 501, such as ROM and RAM. The ROM included in the storage unit 502 is, for example, a flash ROM that is nonvolatile memory. The storage unit 502 stores a control program 502a for controlling the center device 5 and the like. Various functions of the control unit 500 are realized by the CPU 501 executing a control program 502 a in the storage unit 502 .

Communication unit 510 may be capable of wireless communication based on another wireless communication scheme.

The center device 5 configured as described above executes a predetermined process upon receiving the trouble occurrence information. In the center device 5 , when the communication section 510 receives the trouble occurrence information transmitted by the electronic device 2 , the control section 500 determines that the user 20 of the electronic device 2 has a problem. Then, the control unit 500 performs processing corresponding to the trouble that has occurred.

For example, the control unit 500 generates trouble notification information that notifies that a trouble has occurred at a position indicated by position information included in the received trouble occurrence information. Then, control unit 500 causes communication unit 510 to transmit the generated trouble notification information to a predetermined communication device. The communication unit 510 may transmit the trouble notification information to a communication device owned by, for example, a police station or a police box. At this time, the communication unit 510 may transmit the trouble notification information to the communication device at the police station or police box closest to the location of the user 20 in trouble. When a communication device provided at a police station or a police box receives trouble notification information, for example, a police officer rushes to the place where the troubled user 20 exists. Further, the communication unit 510 may transmit trouble notification information to a communication device owned by a security company. When the communication device provided by the security company receives the trouble notification information, for example, a security guard rushes to the place where the troubled user 20 exists. Further, when a contact device is associated in advance with identification information included in the received trouble occurrence information, communication unit 510 may transmit trouble notification information to the contact device. . If user 20 is a child, the contact device may be, for example, user 20's parent's cell phone or school communication device.

Note that the operation of the center device 5 when the center device 5 receives trouble occurrence information is not limited to the above. Further, although the electronic device 2 transmits trouble occurrence information when the operation button 220 is operated, the trouble occurrence information may be transmitted according to other input to the electronic device 2 . For example, consider a case where the electronic device 2 has a microphone. In this case, the electronic device 2 may transmit trouble occurrence information when a predetermined voice uttered by the user 20 is input to the microphone. As another example, consider a case where the electronic device 2 includes an acceleration sensor that detects vibration of the electronic device 2 . In this case, the electronic device 2 may transmit trouble occurrence information when the acceleration sensor detects a predetermined vibration applied to the electronic device 2 by the user 20 .

<Operation example of communication system>
FIG. 8 is a flow chart showing an example of the operation of the electronic device 2. As shown in FIG. When the user 20 inputs a start instruction, the electronic device 2 starts executing the process of FIG. Then, the electronic device 2 repeatedly executes the process of FIG. 8 until the user 20 inputs an end instruction. The user 20 can input a start instruction to the electronic device 2 by performing a predetermined operation on the display screen 250a of the electronic device 2, for example. Further, the user 20 can input a termination instruction to the electronic device 2 by performing a predetermined operation on the display screen 250a of the electronic device 2, for example. Hereinafter, the electronic device 2 to be described may be referred to as the target electronic device 2 . Also, the user 20 of the target electronic device 2 may be called the target user 20 or the target pedestrian 20 .

As shown in FIG. 8, in step s1, the control unit 200 of the target electronic device 2 generates device information regarding the target electronic device 2. FIG. The device information includes the latest position information acquired by the receiving unit 230 , the identification information of the target electronic device 2 , and the current moving speed of the target electronic device 2 . It can be said that the moving speed of the target electronic device 2 is the moving speed of the target user 20 . The control unit 200 can obtain the current moving speed of the target user 20, for example, based on a plurality of pieces of position information acquired by the receiving unit 230 at different times. If the target electronic device 2 includes an acceleration sensor, the moving speed of the target electronic device 2 may be obtained based on the detection result of the acceleration sensor. Hereinafter, simply speaking of moving speed means the moving speed of the electronic device 2 .

After step s1, in step s2, the control unit 200 causes the communication unit 210 to transmit the generated device information to the surrounding roadside devices 3. FIG. At this time, the communication unit 210 broadcasts the device information to the surrounding roadside devices 3 using, for example, the 700 MHz band. After step s2, step s1 is executed again. Thereafter, the target electronic device 2 operates similarly. The target electronic device 2 repeatedly transmits the device information to the surrounding roadside devices 3 .

In the first step s2 after the start instruction is input, the target electronic device 2 transmits the start instruction information to the surrounding roadside devices 3 together with the device information. Further, when the end instruction is input, the target electronic device 2 transmits the end instruction information to the surrounding roadside devices 3 .

FIG. 9 is a flow chart showing an example of the operation of the roadside device 3. FIG. As shown in FIG. 9, when the communication unit 310 of the roadside device 3 receives the device information from the target electronic device 2 in step s11, step s12 is executed. Since the communication distance of communication using the 700 MHz band is not very long, when the roadside device 3 can directly receive the device information from the target electronic device 2, the target electronic device 2 exists at a position close to the roadside device 3. It can be said that

At step s<b>12 , the control section 300 causes the communication section 310 to transmit the received device information to the center device 5 . If the communication unit 310 receives the start instruction information together with the device information in step s11, the control unit 300 causes the communication unit 310 to transmit the device information and the start instruction information to the center device 5 in step s12. . After step s12, when step s11 is executed again, the roadside unit 3 operates in the same manner thereafter. The roadside device 3 transmits the received device information to the center device 5 every time it receives the device information from the target electronic device 2 . In the roadside device 3 , when the communication section 310 receives the end instruction information, the control section 300 causes the communication section 310 to transmit the end instruction information to the center device 5 . Hereinafter, the roadside device 3 that receives device information from the target electronic device 2 may be referred to as the target roadside device 3 .

FIG. 10 is a flow chart showing an example of the operation of the center device 5. FIG. When receiving the start instruction information from the target roadside device 3, the center device 5 executes the processing in FIG. Further, when the center device 5 receives end instruction information from the target roadside device 3 during execution of the processing of FIG. 10, it ends the processing of FIG. The center device 5 repeatedly receives the device information of the target electronic device 2 while executing the process of FIG.

As shown in FIG. 10 , in step s21, the control section 500 of the center device 5 determines whether or not the route or range of movement of the target user 20 is registered in the center device 5 . In other words, the control unit 500 determines whether or not the route or range of movement of the target user 20 is stored in the storage unit 502 .

Here, in this example, the route or range of movement of the user 20 of the electronic device 2 may be stored in the storage unit 502 in association with the identification information of the electronic device 2 . For example, when the user 20 of the electronic device 2 is a child, the school route from home to school of the user 20 may be associated with the identification information of the electronic device 2 and stored in the storage unit 502 . Further, when the user 20 of the electronic device 2 is an elderly person, the walking range in which the user 20 walks may be stored in the storage unit 502 in association with the identification information of the electronic device 2 . Hereinafter, the term "route" simply means the route along which the user 20 moves. Further, simply speaking of range means the range in which the user 20 moves. Also, a route and a range may be collectively referred to as a route or the like.

The route or the like registered in the center device 5 is input to, for example, the electronic device 2 and transmitted from the electronic device 2 to the center device 5 . For example, by performing a predetermined operation on the display screen 250 a of the electronic device 2 , a route or the like is input to the electronic device 2 . The electronic device 2 transmits the input route and the like and the identification information of the electronic device 2 to the center device 5 . The center device 5 associates the route or the like and the identification information transmitted from the electronic device 2 with each other and stores them in the storage unit 502 . As a result, the route and the like are registered in the center device 5 .

In step s21, if the route or the like corresponding to the identification information included in the device information of the target electronic device 2 is stored in the storage section 502, the control section 500 stores the route or the like along which the target user 20 moves. 5 is registered. On the other hand, if the route or the like corresponding to the identification information included in the device information of the target electronic device 2 is not stored in the storage unit 502, the control unit 500 stores the route or the like along which the target user 20 moves. It is determined that it is not registered in Henceforth, the route which the target user 20 moves may be called a target route. Moreover, the range in which the target user 20 moves may be called a target range. Also, the target route and the target range may be collectively referred to as the target route or the like.

If YES is determined in step s21, step s22 is executed. On the other hand, if NO is determined in step s21, step s23 is executed. In step s22, the control unit 500 determines whether or not the target electronic device 2 is positioned outside the target route or the like. In other words, the control unit 500 determines whether or not the target user 20 is located outside the target route or the like. When the target route is registered in the center device 5, in step s22, the control unit 500 determines whether or not the target electronic device 2 is positioned outside the target route. For example, when a school route is registered as the target route, the control unit 500 determines whether or not the target electronic device 2 is located outside the school route. Further, when the target range is registered in the center device 5, in step s22, the control unit 500 determines whether or not the target electronic device 2 is located outside the target range. For example, when a walk range is registered as the target range, the control unit 500 determines whether the target electronic device 2 is located outside the walk range. The control unit 500 determines whether the target electronic device 2 is located outside the target route or the like based on the position information included in the latest device information received from the target roadside device 3 (that is, the latest position information of the target electronic device 2). determine whether or not to

If YES is determined in step s22, step s25 is executed. That is, when it is determined that the target electronic device 2 is positioned outside the target route or the like, step s25 is executed. On the other hand, if NO is determined in step s22, step s23 is executed. That is, when it is determined that the target electronic device 2 is located in the target route or the like, step s23 is executed.

In step s<b>23 , the control unit 500 determines whether or not the means of transportation used by the target user 20 is registered in the center device 5 . In other words, the control unit 500 determines whether or not the storage unit 502 stores transportation means information indicating the transportation means used by the target user 20 .

Here, in this example, transportation means information indicating the transportation means used by the user 20 of the electronic device 2 may be stored in the storage unit 502 in association with the identification information of the electronic device 2 . The mode of transportation indicated by the mode of transportation information includes walking, bicycles, and the like. For example, when the user 20 of the electronic device 2 is a child, transportation means information indicating a bicycle as the transportation means used by the user 20 is associated with the identification information of the electronic device 2 and stored in the storage unit 502. Sometimes. Further, when the user 20 of the electronic device 2 is an elderly person, transportation means information indicating walking as the transportation means used by the user 20 is stored in the storage unit 502 in association with the identification information of the electronic device 2. There is something. When the route or the like and transportation means information for the same user 20 are stored in the storage unit 502, the route or the like that the user 20 moves and the transportation means that the user 20 uses on the route or the like are stored in the center. It can be said that it is registered with the device 5 . Henceforth, simply speaking of means of transportation means means of transportation used by the user 20 .

The means of transportation information is input to, for example, the electronic device 2 and input from the electronic device 2 to the center device 5 . For example, the means of transportation information is input to the electronic device 2 by performing a predetermined operation on the display screen 250a. The electronic device 2 transmits the inputted transportation means information and the identification information of the electronic device 2 to the center device 5 . The center device 5 associates the transportation means information and the identification information transmitted from the electronic device 2 with each other and stores them in the storage unit 502 . As a result, the means of transportation is registered in the center device 5 .

In step s23, if the transportation means information corresponding to the identification information included in the device information of the target electronic device 2 is stored in the storage unit 502, the control unit 500 determines that the transportation means used by the target user 20 is the center. It is determined that the device 5 is registered. On the other hand, when the transportation means information corresponding to the identification information included in the device information of the target electronic device 2 is not stored in the storage unit 502, the control unit 500 determines that the transportation means used by the target user 20 is the center device. 5 is not registered. Henceforth, the means of transportation used by the target user 20 may be called a target means of transportation.

If YES is determined in step s23, step s24 is executed. On the other hand, if NO is determined in step s23, the process of FIG. 10 ends. In step s24, the control unit 500 determines whether or not the current moving speed of the target electronic device 2 is abnormal based on the target moving means. In other words, the control unit 500 determines whether or not the current moving speed of the target user 20 is abnormal based on the target moving means. The control unit 500 uses the moving speed included in the latest device information received from the target roadside device 3 as the current moving speed of the target electronic device 2 .

In step s24, the control unit 500 determines that the current moving speed of the target electronic device 2 is abnormal if, for example, the current moving speed of the target electronic device 2 is greater than a threshold value corresponding to the target moving means. judge. On the other hand, the control unit 500 determines that the current moving speed of the target electronic device 2 is not abnormal when the current moving speed of the target electronic device 2 is equal to or less than the threshold value according to the target moving means.

The storage unit 502 stores threshold values used in step s24 for each type of means of transportation. For example, the storage unit 502 stores a speed of 6 km/h as a threshold for walking. The threshold corresponding to walking is set, for example, to a value that is greater than the general moving speed when moving on foot. Also, a threshold value corresponding to a bicycle, for example, 25 km/h is stored in the storage unit 502 . The threshold corresponding to the bicycle is set, for example, to a value that is higher than the general traveling speed when traveling by bicycle.

For example, when the target mode of transportation is walking, the control unit 500 uses a speed of 6 km/h as a threshold value corresponding to the target mode of transportation. Then, when the current moving speed of the target electronic device 2 is higher than 6 km/h, the control unit 500 determines that the current moving speed of the target electronic device 2 is abnormal. Further, when the target transportation means is, for example, a bicycle, the control unit 500 uses a speed of 25 km/h as the threshold corresponding to the target transportation means. Then, when the current moving speed of the target electronic device 2 is higher than 25 km/h, the control unit 500 determines that the current moving speed of the target electronic device 2 is abnormal. If it is determined that the current moving speed of the target electronic device 2 is abnormal, it can be said that there is a high possibility that the target user 20 is not moving by the target transportation means.

If YES is determined in step s24, step s25 is executed. On the other hand, if the determination in step s24 is NO, step s21 is executed again, and thereafter the center device 5 operates in the same manner. If the target electronic device 2 does not deviate from the target route or the like and the moving speed of the target electronic device 2 is not abnormal, the center device 5 repeats the processing of steps s21 to s24.

In this example, when the determination in step s22 is YES, the center device 5 determines that the target user 20 has trouble, and executes step s25. Further, when the determination in step s24 is YES, the center device 5 determines that the target user 20 has trouble, and executes step s25. In step s25, the center device 5 sends the target roadside device 3 a first photographing save notification instructing the target roadside device 3 to photograph and save the obtained photographed image. In step s25, the control unit 500 generates first notification information for performing the first shooting save notification. The first notification information includes identification information of the target electronic device 2 . Then, the control unit 500 causes the communication unit 510 to transmit the first notification information to the target roadside device 3 . As a result, the target roadside device 3 is notified of the first image storage. The operation of the target roadside device 3 when the target roadside device 3 receives the first notification information will be described later.

After step s25, in step s26, the control unit 500 determines whether or not a contact address in case trouble occurs in the target user 20 is registered in the center device 5 or not. In this example, contact information indicating a contact address in case trouble occurs in the user 20 of the electronic device 2 may be stored in the storage unit 502 in association with the identification information of the electronic device 2 . For example, when the user 20 of the electronic device 2 is a child, the mobile phone of the user 20's parent or the communication device of the school is adopted as the contact information. If the user 20 is an elderly person, for example, the mobile phone of the user 20's child or the communication device of a facility such as a nursing home is adopted as the contact information. Contact information includes, for example, the email address of the contact device. Note that the contact information is not limited to this example.

The contact information is input to, for example, the electronic device 2 and input to the center device 5 from the electronic device 2 . For example, the contact information is input to the electronic device 2 by performing a predetermined operation on the display screen 250a. The electronic device 2 transmits the input contact information and identification information of the electronic device 2 to the center device 5 . The center device 5 associates the contact information and the identification information transmitted from the electronic device 2 with each other and stores them in the storage unit 502 . As a result, a contact address is registered in the center device 5 in case the user 20 has a problem.

In step s26, if the contact information corresponding to the identification information included in the device information of the target electronic device 2 is stored in the storage unit 502, the control unit 500 determines whether the target user 20 has trouble. It is determined that the contact is registered in the center device 5 . On the other hand, if the contact information corresponding to the identification information included in the device information of the target electronic device 2 is not stored in the storage unit 502, the control unit 500 can contact the target user 20 when trouble occurs. It is determined that the destination is not registered in the center device 5. Henceforth, the contact point in case trouble occurs in the target user 20 may be called a target contact point.

If YES is determined in step s26, step s27 is executed. On the other hand, if NO is determined in step s26, step s28 is executed. In step s27, the center device 5 notifies the target contact based on the contact information of the target contact in the storage unit 502. FIG. In step s27, the control unit 500 generates second notification information for notifying the target user 20 that trouble has occurred. Then, the control unit 500 causes the communication unit 510 to transmit the second notification information to the target contact.

If the target contact that has received the second notification information is, for example, a mobile phone, the mobile phone notifies the user that the target user 20 has encountered a problem. For example, consider the case where the target user 20 is a child and the target contact is the mobile phone of the target user 20's parent. In this case, the mobile phone of the parent of the target user 20 who has received the second notification information notifies the parent that the child is in trouble. For example, a mobile phone displays information notifying a child that trouble has occurred. Also, the mobile phone may output a sound from the speaker to notify the child that trouble has occurred.

As another example, consider the case where the target user 20 is elderly and the target contact is the mobile phone of the target user 20's child. In this case, the mobile phone of the child of the target user 20 who has received the second notification information notifies the child that the trouble has occurred with the parent. For example, a mobile phone displays information notifying a parent that trouble has occurred. Also, the mobile phone may output a sound from the speaker to notify the parent that trouble has occurred. Note that the operation of the device of the contact that received the second notification information is not limited to this.

After step s27, the center device 5 requests the target electronic device 2 to contact in step s28. At step s28, the control unit 500 generates contact request information for requesting contact. Then, the control unit 500 causes the communication unit 510 to transmit the contact request information to the target electronic device 2 .

The target electronic device 2 that has received the contact request information notifies the target user 20 that contact is requested. At this time, for example, the control unit 200 of the target electronic device 2 may sound the buzzer 240 to notify the target user 20 that contact is requested. Also, the control unit 200 may display on the display unit 250 information notifying that contact is requested. The target user 20 notified that the contact is requested instructs the target electronic device 2 to make the contact. The target user 20 may instruct the target electronic device 2 to make contact, for example, by operating the display screen 250a. Further, the target user 20 may instruct the target electronic device 2 to contact by operating the operation button 220 .

In the target electronic device 2 instructed to contact by the target user 20, the control unit 200 generates contact information. Then, the control unit 200 causes the communication unit 210 to transmit the contact information to the center device 5 . Contact information may include fixed information. The fixed information may be, for example, information that notifies that trouble has occurred, information that notifies that help is sought, or other information. Also, the contact information may include information input to the target electronic device 2 by the target user 20 . The target user 20 who has had trouble inputs, for example, information indicating the details of the trouble that has occurred to the target electronic device 2 . The target user 20 can input information to the target electronic device 2 by operating the display screen 250a, for example.

It should be noted that the target user 20 in trouble may not be able to instruct the target electronic device 2 to make a contact. For example, when the target user 20 is involved in a crime and the body of the target user 20 is restrained, the target user 20 cannot instruct the target electronic device 2 to make contact. There is Further, when the target user 20 is urgently transported to a hospital or the like, the target user 20 may not be able to instruct the target electronic device 2 to make a contact. In such a case, contact information is not transmitted from the target electronic device 2 .

After step s28, in step s29, the control unit 500 determines whether or not there is a contact from the target electronic device 2. The control unit 500 determines that there has been a contact from the target electronic device 2 when the communication unit 510 receives the contact information within a predetermined period of time after transmitting the contact request information. On the other hand, if the communication unit 510 does not receive the contact information within the predetermined time after the transmission of the contact request information, the control unit 500 determines that there has been no contact from the target electronic device 2. do. If YES is determined in step s29, the process of FIG. 10 ends. On the other hand, if NO is determined in step s29, step s28 is executed again and the contact request information is transmitted to the target electronic device 2 again. After that, step s29 is executed, and thereafter the center device 5 operates in the same way.

The center device 5 that has received the contact information may, for example, transmit the received contact information to the registered target contact. In this case, the target contact's device notifies the user of the device of the information contained in the contact information. Thereby, the user of the device of the target contact can know the situation of the target user 20 in which the trouble occurred.

Thus, in this example, when the target electronic device 2 is positioned outside the target route or the like, it is determined that the target user 20 has a problem. Therefore, even if the target user 20 having trouble cannot operate the operation button 220, the processing device 7 can execute the process for dealing with the trouble. Further, when the current moving speed of the target electronic device 2 is abnormal, it is determined that the target user 20 has trouble. Therefore, even if the target user 20 having trouble cannot operate the operation button 220, the processing device 7 can execute the process for dealing with the trouble. For example, the processing device 7 can notify the registered contact that the user 20 has encountered a problem.

For example, consider a case where a child is abducted or kidnapped on the way to school. In this case, although the child may not be able to operate the operation button 220, the electronic device 2 possessed by the child is likely to be located outside the school route. Therefore, in this case, the processing device 7 can determine that the child is in trouble. Therefore, even if the operation button 220 of the electronic device 2 possessed by the child is not operated, the processing device 7 can execute the processing for dealing with the trouble that has occurred to the child.

As another example, let us consider a case where the physical condition of an elderly person suddenly deteriorates and the elderly person is urgently transported. In this case, although the elderly may not be able to operate the operation buttons 220, there is a high possibility that the movement speed of the electronic device 2 possessed by the elderly will be extremely high. Therefore, in this case, the processing device 7 can determine that trouble has occurred in the elderly. Therefore, even if the operation button 220 of the electronic device 2 possessed by the elderly person is not operated, the processing device 7 can execute the process for dealing with the trouble that has occurred to the elderly person.

FIG. 11 is a flow chart showing an example of the operation of the target roadside device 3 to which the center device 5 issues the first photographed storage notification. As shown in FIG. 11, when the communication unit 310 of the target roadside device 3 receives the first notification information in step s31, step s32 is executed. In other words, when the target roadside device 3 is notified of the first image storage, step s32 is executed.

In step s32, the control unit 300 executes processing in response to the first shooting save notification. In step s32, the control unit 300 causes the camera 320 to start moving image shooting if the camera 320 is not shooting when the first shooting saving notification is received. Then, when camera 320 shoots a moving image for a predetermined time (for example, several seconds to several tens of seconds), control unit 300 saves the captured image obtained by camera 320 in storage unit 302 as a first trouble occurrence image. At this time, the control unit 300 stores the first trouble occurrence image in the storage unit 302 in association with the identification information of the target electronic device 2 included in the first notification information. The control unit 300 stores the first trouble occurrence image and the identification information of the target electronic device 2 in the non-volatile memory of the storage unit 302 . The first trouble-occurrence image is a moving image captured by the camera 320 for a predetermined period of time. The first trouble-occurrence image generated when YES is determined in step s22 includes an image captured by the camera 320 immediately after it is determined that the target electronic device 2 is positioned outside the target route or the like. . Further, the first trouble occurrence image generated when the determination in step s24 is YES includes the image captured by the camera 320 immediately after it is determined that the current moving speed of the target electronic device 2 is abnormal. is included. For example, the target roadside device 3 does not automatically delete the image at the time of first trouble occurrence from the storage unit 302, but deletes it from the storage unit 302 when a deletion instruction is given from the outside of the target roadside device 3. . The target roadside device 3 may transmit the first trouble occurrence time image and the identification information associated therewith to the center device 5 or to another device.

On the other hand, if the camera 320 is shooting when the communication unit 310 receives the first shooting save notification, the control unit 300 switches the camera during the first specific period determined based on the timing of receiving the first shooting save notification. The captured image obtained in 320 is stored in the storage unit 302 as an image different from the captured image obtained by the camera 320 outside the first specific period. In other words, the control unit 300 saves the captured image obtained by the camera 320 during the first specific period in the storage unit 302 as an image file separate from the captured image obtained by the camera 320 outside the first specific period. . Furthermore, in other words, the control unit 300 stores the moving image captured by the camera 320 during the first specific period in the storage unit 302 as a different moving image from the moving images captured by the camera 320 outside the first specific period. It can be said that the first specific period is a period determined based on the target roadside device 3 having received the first image storage notification. The control unit 300 stores the moving image captured by the camera 320 in the first specific period in the non-volatile memory of the storage unit 302 in association with the identification information of the target electronic device 2 . Control unit 300 may also store moving images captured by camera 320 outside the first specific period in the non-volatile memory of storage unit 302 .

Here, the timing that is the first predetermined time before the timing at which the target roadside device 3 receives the first image storage notification (in other words, the timing at which the target roadside device 3 receives the first notification information) is defined as the first timing. Also, the second timing is the timing after the second predetermined time from the timing when the target roadside device 3 receives the first image storage notification. As the first specific period, for example, a period from the first timing to the second timing is adopted. Each of the first and second predetermined times is set, for example, from several seconds to several tens of seconds. The first predetermined time and the second predetermined time may be the same or different. Also, as the first specific period, a period from the timing when the target roadside device 3 receives the first photographing save notification to the second timing may be employed. Hereinafter, an image captured by the camera 320 during the first specified period (in other words, a moving image captured by the camera 320 during the first specified period) may be referred to as a first specified period image. Also, an image captured by the camera 320 outside the first specific period may be referred to as an image outside the first specific period.

For example, the target roadside device 3 does not automatically delete the first specific period image from the storage unit 302 , and deletes it from the storage unit 302 when a deletion instruction is given from outside the target roadside device 3 . The target roadside device 3 may transmit the first specific period image and the identification information associated therewith to the center device 5 or to another device. Further, the target roadside device 3 may transmit the image outside the first specific period to the center device 5 .

When storing the first specific period image, the control unit 300 associates the identification information for identifying the first specific period image, the first specific period image, and the identification information of the target electronic device 2 with each other. You may save in the memory|storage part 302. FIG. Also, the control unit 300 may store the first specific period image and the image outside the first specific period in separate storage areas. In this case, the storage unit 302 has a first storage area for storing images of the first specific period and a second storage area for storing images outside the first specific period. In the target roadside device 3, when a plurality of first specific period images are obtained, the plurality of first specific period images are stored in the first storage area.

As described above, when it is determined that the target electronic device 2 is located outside the target route or the like (YES in step s22), the target roadside device 3 is notified of the first photographing save. Therefore, the first specific period image when it is determined that the target electronic device 2 is positioned outside the target route or the like is the period determined based on the determination that the target electronic device 2 is positioned outside the target route or the like. It can be said that this is a photographed image obtained by the target roadside device 3 . The image captured by the camera 320 when the target electronic device 2 is determined to be located outside the target route or the like is included in the first specific period image when the target electronic device 2 is determined to be positioned outside the target route or the like. Contains images. In addition, the first specific period image includes a photographed image obtained by the camera 320 immediately after it is determined that the target electronic device 2 is positioned outside the target route or the like. Also, the first specific period image includes a photographed image obtained by the camera 320 immediately before it is determined that the target electronic device 2 is positioned outside the target route or the like.

Further, when it is determined that the current moving speed of the target electronic device 2 is abnormal (YES in step s24), the target roadside device 3 is notified of the first photographed save. Therefore, the first specific period image when it is determined that the current moving speed of the target electronic device 2 is abnormal is determined based on the determination that the current moving speed of the target electronic device 2 is abnormal. It can be said that this is a photographed image obtained by the target roadside unit 3 during the period. The first specific period image when the current moving speed of the target electronic device 2 is determined to be abnormal includes the image obtained by the camera 320 when the current moving speed of the target electronic device 2 is determined to be abnormal. The captured image is included. Also, the first specific period image includes a photographed image obtained by the camera 320 immediately after it is determined that the current moving speed of the target electronic device 2 is abnormal. In addition, the first specific period image includes a photographed image obtained by the camera 320 immediately before it is determined that the current moving speed of the target electronic device 2 is abnormal.

After execution of step s32, in step s33, the target roadside device 3 sends a second photographing save notification instructing the vehicle 4 around the target roadside device 3 to photograph and save the obtained photographed image. I do. At step s33, the control unit 300 generates third notification information for sending the second photographing save notification to the surrounding vehicles 4. FIG. The third notification information includes identification information of the target electronic device 2 . Then, the control unit 300 causes the communication unit 310 to transmit the third notification information to the surrounding vehicles 4 . At this time, the communication unit 310 broadcasts the third notification information to the surrounding vehicles 4 using, for example, the 700 MHz band. As a result, the second image storage notification is sent to the vehicles 4 around the target roadside unit 3 . After step s33, the process of FIG. 11 ends. After step s31 is executed again, the target roadside unit 3 operates in the same manner.

In the vehicle 4, when the communication unit 410 of the in-vehicle device 40 receives the third notification information, the control unit 400 executes a process according to the second image storage notification by the third notification information. The processing in response to the second image-storage notification regarding the vehicle-mounted device 40 is the same as the processing in response to the first image-storage notification regarding the target roadside device 3 . Specifically, if the camera 470 is not shooting when the second shooting save notification is received, the control unit 400 causes the camera 470 to start movie shooting. Then, when camera 470 shoots a moving image for a predetermined time (for example, several seconds to several tens of seconds), control unit 400 saves the captured image obtained by camera 470 in storage unit 402 as a second trouble occurrence image. At this time, the control unit 400 stores the second trouble occurrence image in the storage unit 402 in association with the identification information of the target electronic device 2 included in the third notification information. The control unit 400 stores the second trouble occurrence image and the identification information of the target electronic device 2 in the non-volatile memory of the storage unit 402 . The second trouble occurrence image is not automatically deleted from the storage unit 402 by the in-vehicle device 40, but is deleted from the storage unit 402 when a deletion instruction is given from outside the in-vehicle device 40, for example. For example, the user inputs an erasure instruction to the in-vehicle device 40 . The in-vehicle device 40 may transmit the second trouble occurrence image and the identification information associated therewith to the center device 5 or to another device.

In this example, the time taken from the determination of YES in step s22 to the execution of step s33 is very short. Therefore, the difference between the timing at which YES is determined in step s22 and the timing at which the in-vehicle device 40 receives the second image save notification is very small. Therefore, in the second trouble occurrence image generated when YES is determined in step s22, it is determined that the target electronic device 2 is positioned outside the target route or the like, as in the first trouble occurrence image. An image captured by camera 470 immediately after is included. Also, in this example, the time taken from the determination of YES in step s24 to the execution of step s33 is very short. Therefore, the image captured by the camera 470 immediately after it is determined that the current moving speed of the target electronic device 2 is abnormal is included in the second trouble occurrence image generated when the determination in step s24 is YES. is included.

On the other hand, if the camera 470 is shooting when the communication unit 410 receives the second shooting save notification, the control unit 400 switches the camera during the second specific period determined based on the timing of receiving the second shooting save notification. The captured image obtained by 470 is saved in the storage unit 402 as an image different from the captured image obtained by the camera 470 outside the second specific period. The control unit 400 associates the moving image captured by the camera 470 in the second specific period with the identification information of the target electronic device 2 and stores it in the non-volatile memory of the storage unit 402 . Control unit 400 may also store moving images captured by camera 470 outside the second specific period in the non-volatile memory of storage unit 402 .

Here, the third timing is the third predetermined time before the timing at which the in-vehicle device 40 receives the second image storage notification. Also, the fourth timing is the timing after the fourth predetermined time from the timing at which the in-vehicle device 40 receives the second image storage notification. As the second specific period, for example, a period from the third timing to the fourth timing is adopted. Each of the third and fourth predetermined times is set, for example, from several seconds to several tens of seconds. The third predetermined time and the fourth predetermined time may be the same or different. At least one of the third predetermined time and the fourth predetermined time may be the same as the first predetermined time described above, or may be the same as the second predetermined time described above. Also, as the second specific period, a period from the timing at which the in-vehicle device 40 receives the second image storage notification to the fourth timing may be adopted. Hereinafter, the captured image obtained by the camera 470 during the second specific period may be referred to as the second specific period image. Also, an image captured by the camera 470 outside the second specific period may be referred to as an image outside the second specific period.

For example, the vehicle-mounted device 40 does not automatically delete the second specific period image from the storage unit 402 , and deletes it from the storage unit 402 when a deletion instruction is given from outside the vehicle-mounted device 40 . The in-vehicle device 40 may transmit the second specific period image and the identification information associated therewith to the center device 5 or to another device. Also, the in-vehicle device 40 may transmit the image outside the second specific period to the center device 5 or may transmit it to another device.

As described above, in this example, the time taken from the determination of YES in step s22 to the execution of step s33 is very short. Therefore, in the second specific period image when it is determined that the target electronic device 2 is positioned outside the target route or the like, similar to the first specific period image, if the target electronic device 2 is positioned outside the target route or the like, The image captured by the camera 470 when determined is included. In addition, the second specific period image includes a photographed image obtained by the camera 470 immediately after it is determined that the target electronic device 2 is positioned outside the target route or the like. Also, the second specific period image includes a photographed image obtained by the camera 470 immediately before it is determined that the target electronic device 2 is positioned outside the target route or the like.

Also, in this example, the time taken from the determination of YES in step s24 to the execution of step s33 is very short. Therefore, when the current moving speed of the target electronic device 2 is determined to be abnormal, the image captured by the camera 470 when the current moving speed of the target electronic device 2 is determined to be abnormal is included in the second specific period image. Includes images captured by Further, the second specific period image includes a photographed image obtained by the camera 470 immediately after it is determined that the current moving speed of the target electronic device 2 is abnormal. In addition, the second specific period image includes a photographed image obtained by the camera 470 immediately before it is determined that the current moving speed of the target electronic device 2 is abnormal.

When storing the second specific period image, the control unit 400 associates the identification information for identifying the second specific period image, the second specific period image, and the identification information of the target electronic device 2 with each other. You may preserve|save in the memory|storage part 402. FIG. Also, the control unit 400 may store the second specific period image and the second non-specific period image in separate storage areas. In this case, the storage unit 402 has a third storage area for storing images of the second specific period and a fourth storage area for storing images outside the second specific period. In the in-vehicle device 40, when a plurality of second specific period images are obtained, the plurality of second specific period images are stored in the third storage area.

It should be noted that the target roadside device 3 does not need to execute the processing according to the first image-storage instruction if the image is being imaged when the first image-storage notification is received. In this case, the first specified period is not determined. That is, the first specific period image and the non-first specific period image are not stored in the storage unit 302 as separate images. Also, if the target roadside device 3 is not in the process of shooting when it receives the first shooting save notification, it does not have to start shooting. In this case, the image at the time of occurrence of the first trouble is not saved in the storage unit 302 .

Further, if the vehicle-mounted device 40 is in the middle of shooting when the second shooting save notification is received, the vehicle-mounted device 40 does not need to execute the process according to the second shooting saving instruction. In this case, the second specific period is not determined. Also, if the vehicle-mounted device 40 is not in the process of shooting when it receives the second shooting save notification, it does not have to start shooting. In this case, the image at the time of occurrence of the second trouble is not saved in the storage unit 402 .

Further, if the determination in step s22 is YES, the center device 5, regardless of whether or not the contact information for when the target user 20 has a problem is registered in the center device 5, may be notified that a trouble has occurred at the location indicated by the location information included in the latest device information. In this case, the center device 5 generates fourth notification information that notifies that trouble has occurred at the location indicated by the location information included in the latest device information. Then, the center device 5 transmits the fourth notification information to a communication device possessed by, for example, a police station or a police box. When the communication device provided at the police station or police box receives the fourth notification information, for example, the police rush to the place where the troubled user 20 exists. Also, the center device 5 may transmit the fourth notification information to a communication device owned by a security company. When the communication device provided by the security company receives the fourth notification information, for example, a security guard rushes to the place where the troubled user 20 exists. Similarly, if the determination in step s24 is YES, the center device 5, regardless of whether or not the contact information for when the target user 20 has trouble is registered in the center device 5, A fourth notification information may be transmitted to the device.

Further, when the target route is registered, the center device 5 may end the processing of FIG. good.

As described above, in this example, when it is determined that the current moving speed of the electronic device 2 around the roadside device 3 is abnormal, the roadside device 3 starts photographing. This increases the possibility that the user 20 of the electronic device 2 whose moving speed is determined to be abnormal appears in the photographed image obtained by the roadside device 3 . Therefore, by checking the photographed image obtained by the roadside device 3, there is a high possibility that the state of the user 20 who is moving at an abnormal speed can be checked. In other words, by checking the photographed image obtained by the roadside device 3, the possibility of being able to check the state of a pedestrian who may have had trouble is increased. Therefore, the convenience of the photographed image obtained by the roadside device 3 is improved. The photographed image obtained by the roadside device 3 is confirmed by, for example, the police.

Further, in this example, when it is determined that the current moving speed of the electronic device 2 in the vicinity of the roadside device 3 is abnormal, the roadside device 3 that is being photographed displays the first specific period image for the first specific period. The image is stored as an image different from the outside image. There is a high possibility that the user 20 of the electronic device 2 whose moving speed is determined to be abnormal appears in the first specific period image. Therefore, by checking the first specific period image, there is a high possibility that the state of the user 20 whose movement speed is abnormal can be checked. Therefore, the convenience of the photographed image obtained by the roadside device 3 is improved.

Further, in this example, based on the means of transportation used by the user 20 of the electronic device 2, it is determined whether or not the current moving speed of the electronic device 2 is abnormal. Accordingly, it is possible to appropriately determine whether or not the current moving speed of the electronic device 2 is abnormal.

Further, in this example, when it is determined that the current moving speed of the electronic device 2 is abnormal, the contact information registered in the processing device 7 is notified. Thereby, the convenience of the processing device 7 is improved.

Further, in this example, when it is determined that the current moving speed of the electronic device 2 in the vicinity of the roadside device 3 is abnormal, the second image storage notification is sent to the vehicle 4 in the vicinity of the roadside device 3. . As a result, there is a high possibility that the user 20 of the electronic device 2 whose moving speed is determined to be abnormal will appear in the photographed image obtained by the vehicle 4 . Therefore, by checking the photographed image obtained by the vehicle 4, it is highly possible to check the state of the user 20 whose moving speed is abnormal. Therefore, the convenience of the photographed image obtained by the vehicle 4 is improved. A photographed image obtained by the vehicle 4 is confirmed by, for example, the police.

Further, in this example, when it is determined that the current moving speed of the electronic device 2 is abnormal, the electronic device 2 is requested to be contacted. By receiving communication from the electronic device 2, the processing device 7 can know the state of the user 20 whose movement speed is abnormal.

Further, in this example, when it is determined that the user 20 of the electronic device 2 near the roadside device 3 is positioned outside the route or the like, the roadside device 3 starts photographing. As a result, there is a high possibility that the user 20 of the electronic device 2 positioned outside the route or the like will appear in the photographed image obtained by the roadside device 3 . Therefore, by confirming the photographed image obtained by the roadside device 3, the possibility of confirming the state of the user 20 who has deviated from the route or the like increases. In other words, by checking the photographed image obtained by the roadside device 3, the possibility of being able to check the state of a pedestrian who may have had trouble is increased. Therefore, the convenience of the photographed image obtained by the roadside device 3 is improved.

Further, in this example, when it is determined that the user 20 of the electronic device 2 in the vicinity of the roadside device 3 is positioned outside the route or the like, the roadside device 3 being photographed displays the second specific period image as the second specific period image. The image is stored as an image different from the out-of-period image. There is a high possibility that the user 20 of the electronic device 2 located outside the route or the like will appear in the second specific period image. Therefore, by checking the second specific period image, there is a high possibility that the state of the user 20 who has deviated from the route or the like can be checked. Therefore, the convenience of the photographed image obtained by the roadside device 3 is improved.

Therefore, by checking the photographed image obtained by the vehicle 4, it is highly possible to check the state of the user 20 who has deviated from the route or the like. Therefore, the convenience of the photographed image obtained by the vehicle 4 is improved.

Further, in this example, when it is determined that the user 20 of the electronic device 2 in the vicinity of the roadside device 3 is positioned outside the route or the like, the electronic device 2 is requested to be contacted. By receiving communication from the electronic device 2 , the processing device 7 can know the state of the user 20 who has deviated from the route or the like.

<Another Operation Example of Communication System 1>
The processing device 7 may determine whether or not the current moving speed of the target electronic device 2 is abnormal based on the means of transportation used by the target user 20 and the user information regarding the target user 20 .

For example, consider a case where the age of the target user 20 is registered as user information on the target user 20 in the center device 5 . In this case, in step s24, if the current moving speed of the target electronic device 2 is greater than the threshold corresponding to the target transportation means and the age of the target user, the control unit 500 of the center device 5 determines that the target electronic device 2 is determined to be abnormal. On the other hand, if the current moving speed of the target electronic device 2 is equal to or less than the threshold value according to the target transportation means and the age of the target user, the control unit 500 determines that the current moving speed of the target electronic device 2 is not abnormal. I judge.

Storage unit 502 stores a threshold value for each combination of means of transportation and age. For example, the storage unit 502 stores a speed of 4 km per hour as a threshold for a person under the age of 12 walking on foot. In addition, the storage unit 502 stores a speed of 6 km/h as a threshold value corresponding to a case where a person aged 12 to 70 moves on foot. In addition, the storage unit 502 stores a speed of 4 km/h as a threshold for a person aged 70 or older who travels on foot. In addition, storage unit 502 stores a speed of 20 km/h as a threshold for a person under the age of 12 traveling by bicycle. In addition, storage unit 502 stores 25 km/h as a threshold value corresponding to a case where a person aged 12 to 70 travels by bicycle. In addition, storage unit 502 stores a speed of 20 km/h as a threshold for a person aged 70 or older who travels by bicycle. The threshold corresponding to the case where a person under the age of 12 moves on foot is set to a value larger than the general moving speed when the person under the age of 12 moves on foot, for example. Other thresholds are similarly set.

For example, if the target mode of transportation is walking and the age of the target user is 10 years old, the control unit 500 uses a speed of 6 km/h as a threshold corresponding to the target mode of transportation and the age of the target user. Then, when the current moving speed of the target electronic device 2 is higher than 6 km/h, the control unit 500 determines that the current moving speed of the target electronic device 2 is abnormal. As another example, when the target transportation means is a bicycle and the age of the target user is 75 years old, the control unit 500 uses 20 km/h as the threshold according to the target transportation means and the target user's age. Then, when the current moving speed of the target electronic device 2 is higher than 20 km/h, the control unit 500 determines that the current moving speed of the target electronic device 2 is abnormal.

Also, consider a case where the gender of the target user 20 is registered in the center device 5 as the user information regarding the target user 20 . In this case, in step s24, if the current moving speed of the target electronic device 2 is greater than a threshold corresponding to the target transportation means and the gender of the target user, the control unit 500 of the center device 5 determines that the target electronic device 2 is determined to be abnormal. On the other hand, when the current moving speed of the target electronic device 2 is equal to or less than the threshold value according to the target transportation means and the gender of the target user, the control unit 500 determines that the current moving speed of the target electronic device 2 is not abnormal. I judge.

The storage unit 502 stores a threshold value for each combination of means of transportation and gender. For example, storage unit 502 stores a speed of 6 km/h as a threshold for a man walking on foot. In addition, a speed of 5 km/h is stored in the storage unit 502 as a threshold corresponding to a case where a woman moves on foot. A speed of 25 km/h is stored in the storage unit 502 as a threshold for a case where a man travels by bicycle. In addition, a speed of 20 km/h is stored in the storage unit 502 as a threshold corresponding to a case where a woman travels by bicycle. The threshold corresponding to the case where the man moves on foot is set to a value higher than the general moving speed when the man moves on foot, for example. Other thresholds are similarly set.

For example, when the target transportation means is walking and the target user is male, the control unit 500 uses a speed of 6 km/h as a threshold according to the gender of the target transportation means and the target user. Then, when the current moving speed of the target electronic device 2 is higher than 6 km/h, the control unit 500 determines that the current moving speed of the target electronic device 2 is abnormal. As another example, when the target transportation means is a bicycle and the target user is a woman, the control unit 500 uses 20 km/h as the threshold according to the gender of the target transportation means and the target user. Then, when the current moving speed of the target electronic device 2 is higher than 20 km/h, the control unit 500 determines that the current moving speed of the target electronic device 2 is abnormal.

User information registered in the center device 5 is input to, for example, the electronic device 2 and transmitted from the electronic device 2 to the center device 5 . For example, user information is input to the electronic device 2 by performing a predetermined operation on the display screen 250a. The electronic device 2 notifies the center device 5 of the input user information and identification information of the electronic device 2 . The center device 5 associates the user information and the identification information transmitted from the electronic device 2 with each other and stores them in the storage unit 502 . User information is thereby registered in the center device 5 .

In this way, by determining whether or not the current moving speed of the target electronic device 2 is abnormal based on the transportation means used by the target user 20 and the user information of the target user 20, the target electronic device It can be determined more appropriately whether the current moving speed of the device 2 is abnormal.

In the above example, the processing device 7 determines whether or not the current moving speed of the electronic device 2 possessed by the user 20 is abnormal based on the means of transportation used by the user 20. It may be determined whether or not the current moving speed of the electronic device 2 is abnormal based on the moving speed that becomes . FIG. 12 is a flow chart showing an example of the operation of the center device 5 in this case. The process of FIG. 12 is such that steps s33 and s34 are executed instead of steps s23 and s24 in the process of FIG. Henceforth, the movement speed used as a reference may be called a reference movement speed.

In the example shown in FIG. 12, in step s33, the control section 500 determines whether or not the reference moving speed for the target electronic device 2 is registered in the center device 5. In the example shown in FIG. In other words, the control unit 500 determines whether or not the reference moving speed for the target electronic device 2 is stored in the storage unit 502 . If YES is determined in step s33, step s34 is executed. On the other hand, if NO is determined in step s33, the process of FIG. 12 ends.

In step s34, the control unit 500 determines whether or not the current moving speed of the target electronic device 2 is abnormal based on the reference moving speed for the target electronic device 2. For example, when the current moving speed of the target electronic device 2 is higher than the reference moving speed, the control unit 500 determines that the current moving speed of the target electronic device 2 is abnormal. On the other hand, when the current moving speed of the target electronic device 2 is equal to or less than the reference moving speed, the control unit 500 determines that the current moving speed of the target electronic device 2 is not abnormal. If YES is determined in step s34, step s25 is executed. Thereafter, the center device 5 operates similarly. On the other hand, if NO is determined in step s34, step s21 is executed again, and thereafter the center device 5 operates in the same manner.

The reference moving speed is input to, for example, the electronic device 2 and transmitted from the electronic device 2 to the center device 5 . For example, the reference movement speed is input to the electronic device 2 by performing a predetermined operation on the display screen 250a. For example, when the user 20 is an elementary school student and moves on foot, a speed of 3 km/h, for example, is input to the electronic device 2 possessed by the user 20 as a reference moving speed. Further, when the user 20 is a high school student and moves on foot, a speed of 6 km/h, for example, is input to the electronic device 2 possessed by the user 20 as a reference moving speed. When the user 20 travels by bicycle, for example, 25 km/h is input as the reference travel speed to the electronic device 2 possessed by the user 20 . The electronic device 2 transmits the input reference moving speed and the identification information of the electronic device 2 to the center device 5 . The center device 5 associates the reference moving speed and the identification information from the electronic device 2 with each other and stores them in the storage unit 502 . Thereby, the reference moving speed is registered in the center device 5 . In step s33, if the reference moving speed corresponding to the identification information included in the device information from the target electronic device 2 is stored in the storage unit 502, the control unit 500 sets the reference moving speed for the target electronic device 2 to the center. It is determined that the device 5 is registered.

Thus, even when the processing device 7 determines whether or not the current moving speed of the electronic device 2 is abnormal based on the reference moving speed, the current moving speed of the electronic device 2 is abnormal.

In the above example, the reference movement speed is set to a value higher than the general movement speed of the user 20 in the transportation means to be used, but the reference movement speed is set to the general movement speed. may In this case, if the current moving speed of the target electronic device 2 is greater than N times the reference moving speed (N>1), the control unit 500 determines that the current moving speed of the target electronic device 2 is abnormal. You may N is set between 1.3 and 2.0, for example.

When the target route is registered in the center device 5, transportation means used by the target user 20 on the partial route may be registered in the center device 5 for each of a plurality of partial routes that constitute the target route. . FIG. 13 is a diagram showing an example of a plurality of partial routes 610 forming the target route 600 and a means of transportation on each partial route 610. As shown in FIG. In the example of FIG. 13, the start point and goal point of the target route 600 are point A and point D, respectively. The target route 600 is composed of a partial route 610a from point A to point B, a partial route 610b from point B to point C, and a partial route 610c from point C to point D. In the example of FIG. 13, walking is registered in the center device 5 as the means of transportation used by the target user 20 on the partial route 610a. Also, in the center device 5, a train of a conventional line is registered as a means of transportation used by the target user 20 on the partial route 610b. A bicycle is registered in the center device 5 as a means of transportation used by the target user 20 on the partial route 610c.

In the example of FIG. 13, in step s24, the control unit 500 selects the partial route 610 on which the target electronic device 2 is currently located, among the plurality of partial routes 610a to 610c, based on the latest position information of the target electronic device 2. identify. Then, the control unit 500 determines whether or not the current moving speed of the target electronic device 2 is abnormal based on the transportation means used by the target user 20 on the partial route 610 on which the target electronic device 2 is located.

For example, consider the case where the target electronic device 2 is located on the partial path 610a. In this case, if the current moving speed of the target electronic device 2 is greater than a threshold corresponding to walking, which is the means of transportation on the partial route 610a, the control unit 500 determines that the current moving speed of the target electronic device 2 is Judged as abnormal.

As another example, consider the case where the target electronic device 2 is located on the partial path 610b. In this case, if the current moving speed of the target electronic device 2 is greater than the threshold corresponding to the train of the conventional train that is the means of transportation on the partial route 610b, the control unit 500 determines the current speed of the target electronic device 2. is determined to be abnormal. For example, a speed of 150 km/h is adopted as the threshold corresponding to a train on a conventional line.

As another example, consider the case where the target electronic device 2 is located on the partial path 610c. In this case, if the current moving speed of the target electronic device 2 is greater than the threshold corresponding to the bicycle, which is the means of transportation on the partial route 610c, the control unit 500 determines that the current moving speed of the target electronic device 2 is Judged as abnormal.

In this way, when the electronic device 2 is located in a partial route included in a plurality of partial routes that constitute the route, the electronic device 2 is determined based on the means of transportation used by the user 20 in the partial route. By determining whether the current moving speed is abnormal, it is possible to more appropriately determine whether the current moving speed of the electronic device 2 is abnormal.

In addition, when the target route is registered in the center device 5 , the reference moving speed may be registered in the center device 5 for each of a plurality of partial routes forming the target route. For example, as in the example of FIG. 13, consider a case where the target route 600 is composed of a plurality of partial routes 610a to 610c. In this case, for example, a speed of 6 km/h is registered in the center device 5 as the reference moving speed corresponding to the partial route 610a. For example, a speed of 150 km/h is registered in the center device 5 as the reference moving speed corresponding to the partial route 610b. For example, a speed of 25 km/h is registered in the center device 5 as the reference moving speed corresponding to the partial route 610c. If the target electronic device 2 is located on the partial route 610a, the control unit 500, in step s34 of FIG. Determine that the speed is abnormal. Further, when the target electronic device 2 is located on the partial route 610b, the control unit 500 determines that the current moving speed of the target electronic device 2 is abnormal if the current moving speed of the target electronic device 2 is greater than 150 km/h. I judge. Then, when the target electronic device 2 is located on the partial route 610c, the control unit 500 determines that the current moving speed of the target electronic device 2 is abnormal when the current moving speed of the target electronic device 2 is greater than 25 km/h. I judge.

In this way, when the electronic device 2 is located in a partial route included in a plurality of partial routes forming the route, the current movement of the electronic device 2 is determined based on the reference movement speed for the partial route. By determining whether the speed is abnormal, it is possible to more appropriately determine whether the current moving speed of the electronic device 2 is abnormal.
