[Technical field]

[0001] The present invention relates to a walking attention calling device, a walking attention calling system, and a server. [Background technology]

[0002] The following Patent Document 1 discloses a device that travels along the road with a child and executes a warning operation when a predetermined condition is met. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] International Publication No. 2019 / 240070 Summary of the Invention [Problem to be solved by the invention]

[0004] It is possible to add a telephone function to the device of Patent Document 1. In this case, there is room for improvement in the warning operation and the operation for notifying the child of the incoming call when the device receives an incoming call from a communication terminal other than the device at the same time as the above-mentioned predetermined condition is satisfied.

[0005] In consideration of the above-mentioned facts, the present invention aims to provide a walking warning device, a walking warning system, and a server that can appropriately control an alarm device when the alarm device is in a state where it can perform two alarm actions simultaneously. [Means for solving the problem]

[0006] The walking attention drawing device according to claim 1 is a walking attention drawing device movable together with a user, comprising: an alarm device capable of executing a first alarm action when it is determined that a first condition that is satisfied when the user should take a safe behavior is satisfied, and capable of executing a second alarm action when it is determined that a second condition different from the first condition is satisfied; and a priority control unit that controls the alarm device so that, when the first condition and the second condition are satisfied simultaneously, one of the first alarm action and the second alarm action is executed in priority to the other action, and when a condition that is one of the first condition and the second condition and corresponds to the one action is no longer satisfied and a condition that is the other of the first condition and the second condition and corresponds to the other action is satisfied, the other action is executed. the safety behavior includes an evacuation behavior, the first condition includes an evacuation condition that is satisfied when a distance from an area in which the user should perform the evacuation behavior to the walking attention drawing device is equal to or less than a second threshold, the second notification action is an incoming call action, and when the evacuation condition and the second condition are satisfied simultaneously, the priority control unit controls the notification device to execute the second notification action in priority to the first notification action. .

[0007] The walking attention calling device according to claim 1 is movable together with the user. The priority control unit controls the notification device to be capable of executing a first notification action when it is determined that a first condition that is satisfied when the user should take a safe action is satisfied, and to be capable of executing a second notification action when it is determined that a second condition different from the first condition is satisfied. Furthermore, the priority control unit controls the notification device to execute one of the first notification action and the second notification action in priority to the other action when the first condition and the second condition are satisfied simultaneously, and to execute the other action when one of the first condition and the second condition, which is a condition corresponding to one of the first and second conditions, is no longer satisfied and the other of the first and second conditions, which is a condition corresponding to the other action, is satisfied. Therefore, the walking attention calling device according to claim 1 is capable of appropriately controlling the notification device when the notification device is in a state in which it is capable of executing two notification actions simultaneously.

[0008] The walking attention warning device of the invention described in claim 2 is the invention of claim 1, wherein the safety behavior includes a safety checking behavior, the first condition includes a safety condition that is met when the distance from an area in which the user should perform the safety checking behavior to the walking attention warning device is equal to or less than a first threshold value, and when the safety condition and the second condition are simultaneously met, the priority control unit controls the alarm device to execute the first alarm action in priority to the second alarm action.

[0009] The priority control unit of the walking attention drawing device described in claim 2 controls the notification device to execute the first notification action in priority to the second notification action when the safety condition and the second condition are simultaneously satisfied. Therefore, when the safety condition and the second condition are simultaneously satisfied, the first notification action prompts the user to execute a safety confirmation action. Therefore, there is little risk that the second notification action will cause the user to stop executing the safety confirmation action.

[0013] Claim 1 The priority control unit of the walking warning device described in controls the warning device to execute the second warning action in priority to the first warning action when the evacuation condition and the second condition are simultaneously satisfied. Therefore, the user can recognize that there is an incoming call to the walking warning device. Furthermore, people around the user recognize that the user is in a situation where they can talk to someone via the walking warning device. Furthermore, the first warning action of the warning device prompts the user to execute evacuation action.

[0016] Claim 3 The walking attention warning system of the invention described in the above comprises a server that wirelessly transmits information for determining whether the first condition and the second condition are satisfied to the walking attention warning device described in the above claim 1 or claim 2, and the walking attention warning device described in the above claim 1 or claim 2.

[0017] Claim 4The server according to the invention described in the above includes an alarm device capable of executing a first alarm action when it is determined that a first condition that is satisfied when a user should take a safe behavior is satisfied, and a second alarm action when it is determined that a second condition different from the first condition is satisfied, and a priority control unit that controls the alarm device to execute one of the first alarm action and the second alarm action in priority to the other action when the first condition and the second condition are satisfied simultaneously, and to execute the other action when a condition that is one of the first condition and the second condition and corresponds to the one action is no longer satisfied and a condition that is the other of the first condition and the second condition and corresponds to the other action is satisfied, and is capable of wirelessly transmitting information for determining whether the first condition and the second condition are satisfied to a walking attention calling device that can be moved together with the user. the safety behavior includes an evacuation behavior, the first condition includes an evacuation condition that is satisfied when a distance from an area in which the user should perform the evacuation behavior to the walking attention drawing device is equal to or less than a second threshold, the second notification action is an incoming call action, and when the evacuation condition and the second condition are satisfied simultaneously, the priority control unit controls the notification device to execute the second notification action in priority to the first notification action. .

[0020] Hereinafter, embodiments of a walking attention calling device, a walking attention calling system, and a server according to the present invention will be described with reference to the drawings.

[0021] As shown in FIG. 1, the embodiment of a walking attention warning system 10 (hereinafter referred to as system 10) has a management server 20 (hereinafter referred to as server 20), a walking attention warning device 30 (hereinafter referred to as device 30), and a mobile terminal 40.

[0022] The server 20 is installed in a building (not shown) owned by the administrator of the system 10.

[0023] 3, the server 20 includes, as its hardware configuration, a CPU (Central Processing Unit) (processor) 21A, a ROM (Read Only Memory) 21B, a RAM (Random Access Memory) 21C, a storage 21D, a wireless communication I / F (Interface) 21E, and an input / output I / F 21G. The CPU 21A, the ROM 21B, the RAM 21C, the storage 21D, the wireless communication I / F 21E, and the input / output I / F 21G are connected to each other so as to be able to communicate with each other via an internal bus 21Z. The CPU 21A and each CPU described later can obtain information related to time from a timer.

[0024] The CPU 21A is a central processing unit that executes various programs and controls each part. The CPU 21A reads out a program from the ROM 21B or the storage 21D, and executes the program using the RAM 21C as a working area. The CPU 21A controls each component and performs various calculation processes according to the program recorded in the ROM 21B or the storage 21D.

[0025] ROM 21B stores various programs and various data. For example, a plurality of programs are installed in ROM 21B. For example, map data 22, a designated area list 25, and information related to user IDs, which will be described later, are recorded in ROM 21B. RAM 21C temporarily stores programs or data as a working area. Storage 21D is composed of a storage device such as an HDD (Hard Disk Drive) or an SSD (Solid State Drive), and stores various programs and various data.

[0026] The map data 22 includes area information including the address of a user US (see FIG. 1) who is a member registered in the system 10. Although only one user US is depicted in FIG. 1, multiple members are registered in the system 10. Therefore, the map data 22 includes information on multiple areas. For example, the map data 22 includes information on the area shown in FIG. 2. In the following description, the map including roads in FIG. 2 is referred to as the map data 22.

[0027] 2, the map data 22 includes images representing seven roads extending in a straight line. That is, the map data 22 includes images representing a first road 22-1, a second road 22-2, a third road 22-3, a fourth road 22-4, a fifth road 22-5, a sixth road 22-6, and a seventh road 22-7.

[0028] A vehicle 60 travels along the first road 22-1, which extends linearly, along the arrow A1. In this specification, the vehicle includes, for example, a four-wheeled vehicle (automobile), a motorized two-wheeled vehicle, and a two-wheeled bicycle. The second road 22-2, the third road 22-3, the fourth road 22-4, the sixth road 22-6, and the seventh road 22-7 are perpendicular to the first road 22-1, and each has one end connected to the first road 22-1. A vehicle 61 travels along the second road 22-2 along the arrow A2, a vehicle 62 travels along the third road 22-3 and the sixth road 22-6 along the arrow A3, a vehicle 63 travels along the fourth road 22-4 along the arrow A4, and a vehicle 64 travels along the seventh road 22-7 along the arrow A7. That is, the first road 22-1, the second road 22-2, the third road 22-3, the fourth road 22-4, the sixth road 22-6, and the seventh road 22-7 are one-way roads. A guardrail 22-4G is provided on the side of the fourth road 22-4. Therefore, the number of traffic accidents on the fourth road 22-4 is less than that on the first road 22-1, the second road 22-2, the third road 22-3, the sixth road 22-6, and the seventh road 22-7.

[0029] Furthermore, a first intersection 22IS-1 is provided at a location where the first road 22-1, the third road 22-3, and the sixth road 22-6 join. A traffic light 23-1 and a traffic light 23-2 are provided at the first intersection 22IS-1. Furthermore, a second intersection 22IS-2 is provided at a location where the first road 22-1, the fourth road 22-4, and the seventh road 22-7 join. No traffic light is provided at the second intersection 22IS-2. Therefore, the number of traffic accidents occurring at the second intersection 22IS-2 is greater than that at the first intersection 22IS-1.

[0030] The fifth road 22-5 is perpendicular to the second road 22-2 and the third road 22-3, and both ends of the fifth road 22-5 are connected to the second road 22-2 and the third road 22-3, respectively. The width of the fifth road 22-5 is significantly narrower than the second road 22-2 and the third road 22-3. Therefore, vehicles cannot actually travel on the road 22-5. Furthermore, suspicious people have been spotted on the road 22-5 in the past.

[0031] The wireless communication I / F 21E is an interface for wireless communication with various devices. For example, the wireless communication I / F 21E can wirelessly communicate with the device 30 and the mobile terminal 40 via a network (e.g., the Internet). The wireless communication I / F 21E can transmit and receive audio data, which will be described later.

[0032] The input / output I / F 21G is an interface for communicating with various devices.

[0033] 4 is a block diagram showing an example of the functional configuration of the server 20. The server 20 has, as its functional configuration, a transmission / reception control unit 211, a SIP control unit 212, and a list management unit 213. These functions are realized by the CPU 21A reading and executing a program stored in the ROM 21B.

[0034] The transmission / reception control unit 211 controls the wireless communication I / F 21E. The wireless communication I / F 21E controlled by the transmission / reception control unit 211 can record data received from the outside in the ROM 21B and the storage 21D, and can wirelessly transmit data recorded in the ROM 21B and the storage 21D to the outside.

[0035] The SIP control unit 212 controls calls between communication terminals using SIP (Session Initiation Protocol). That is, the server 20 has a function as a SIP server. The communication terminals include the device 30 and the mobile terminal 40.

[0036] The list management unit 213 manages the designated area list 25 (see FIG. 5) recorded in the ROM 21 B. The designated area list 25 includes information indicating a user ID, a designated area, and an area type.

[0037] The designated area is an area that is included in the map data 22 and that is designated by a parent (described later) using the mobile terminal 40. Note that each designated area is actually location information that represents each designated area.

[0038] The area type is the type of the specified area. The area types in this embodiment include a safety confirmation area and an evacuation area. The safety confirmation area is an area where the user US should take safety confirmation action. For example, an area where many traffic accidents have occurred in the past can be set as a safety confirmation area. The safety confirmation action includes, for example, visual monitoring of vehicles traveling around the user. The evacuation area is an area where the user US should quickly take evacuation action from the area when the user US enters the area. For example, an area where a suspicious person has been spotted in the past can be set as an evacuation area. Note that the safety confirmation action and the evacuation action are included in the safety action.

[0039] In the map data 22, the third road 22-3, the second intersection 22IS-2, and the fifth road 22-5 are set as the designated area. Furthermore, the third road 22-3 and the second intersection 22IS-2 are set as area types as safety confirmation areas, and the fifth road 22-5 is set as area type as an evacuation area.

[0040] Furthermore, when the list management unit 213 receives update information from the mobile terminal 40, as described below, it sets (changes) the designated area and area type in the designated area list 25 based on the update information.

[0041] Furthermore, the wireless communication I / F 21E controlled by the transmission / reception control unit 211 wirelessly transmits information (location information) about the designated areas included in the latest designated area list 25 and information about the area type to the device 30 having the same user ID as the designated area list 25 every time a predetermined time has elapsed. That is, the wireless communication I / F 21E wirelessly transmits the latest update information to the device 30 every time a predetermined time has elapsed.

[0042] As shown in Fig. 1, the device 30 is detachably attached to a school bag (randoseru) SB worn by a user US who is a child. When traveling between home and school, the user US may walk on various roads 22-1, 22-2, 22-3, 22-4, 22-5, a sixth road 22-6, a seventh road 22-7, and intersections 22IS-1 and 22IS-2 shown in Fig. 2.

[0043] 3, the device 30 has a hardware configuration similar to that of the server 20. That is, the device 30 has, as its hardware configuration, a CPU 31A, a ROM 31B, a RAM 31C, a storage 31D, a wireless communication I / F 31E, an input / output I / F 31G, and an internal bus 31Z. For example, a plurality of programs are installed in the ROM 31B.

[0044] As shown in FIG. 6, the device 30 includes a GPS (Global Positioning System) receiver 32, a first vibrator (alarm device) 33, a second vibrator (alarm device) 34, a third vibrator (alarm device) 35, a speaker 36, and a microphone 37. The GPS receiver 32 receives GPS signals transmitted from GPS satellites to obtain information about the location of the device 30 (hereinafter referred to as "location information"). The first vibrator 33 performs a vibration operation as a first notification operation (alarm operation for safety confirmation) when a safety condition described later as a first condition is satisfied. The second vibrator 34 performs a vibration operation as a first notification operation (alarm operation for evacuation) when an evacuation condition described later as a first condition is satisfied. The third vibrator 35 performs a vibration operation as a second notification operation when a second condition described later is satisfied. When the first vibrator 33, the second vibrator 34, or the third vibrator 35 vibrates, the vibration is transmitted to the body of the user US through the case (not shown) constituting the outer shape of the device 30 and the school bag SB, so that the user US can recognize that the device 30 is vibrating. Since the vibration modes of the first vibrator 33, the second vibrator 34, and the third vibrator 35 are different from each other, the user US can recognize which of the first vibrator 33, the second vibrator 34, and the third vibrator 35 is vibrating. The speaker 36 can output various sounds. For example, the speaker 36 can output sounds based on voice data received from the mobile terminal 40 via the server 20. Various sounds are input to the microphone 37. For example, a voice uttered by the user US is input to the microphone 37. The GPS receiver 32, the first vibrator 33, the second vibrator 34, the third vibrator 35, the speaker 36 and the microphone 37 are capable of communicating with the input / output I / F 31G.

[0045] 7 is a block diagram showing an example of the functional configuration of device 30. As functional components, device 30 has a transmission / reception control unit 311, a condition determination unit 312, a call control unit 313, and a vibrator control unit (priority control unit) 314. These functions are realized by CPU 31A reading and executing a program stored in ROM 31B.

[0046] The transmission / reception control unit 311 controls the wireless communication I / F 31E. The wireless communication I / F 31E controlled by the transmission / reception control unit 311 is capable of wireless communication with the server 20 and the mobile terminal 40 via the network.

[0047] The condition determination unit 312 calculates a distance D between the current position of the device 30 and the designated area, based on the position information received by the GPS receiver 32 and information about the designated area (update information described later) received by the wireless communication I / F 31E from the server 20. For example, when the device 30 is located at position P1 in Fig. 2, the condition determination unit 312 calculates a distance D between positions P1 and P2, based on the position information (update information) of position P2 at one end of the third road 22-3, which is the designated area, and the position information of position P1.

[0048] The condition determination unit 312 determines that the safety condition is satisfied for the designated area when the distance D between the current location of the device 30 and the designated area whose area type is a safety confirmation area is equal to or less than a predetermined first threshold. Furthermore, the condition determination unit 312 determines that the evacuation condition is satisfied for the designated area when the distance D between the current location of the device 30 and the designated area whose area type is an evacuation area is equal to or less than a predetermined second threshold. For example, the first threshold is 1.0 (m) and the second threshold is 2.0 (m). However, the first threshold and the second threshold may be different in size. Also, the first threshold and the second threshold may be the same in size. For example, the first threshold and the second threshold may be 0 (m). In the following description, the designated area whose area type is a safety confirmation area is referred to as a "safety designated area", and the designated area whose area type is an evacuation area is referred to as a "evacuation designated area".

[0049] The call control unit 313 controls the speaker 36 and the microphone 37. For example, regardless of whether or not the call application installed in the ROM 31B is activated, when the device 30 receives an incoming call using SIP from a communication terminal (e.g., a mobile terminal 40) other than the device 30, the second condition is established. Furthermore, when the second condition is established, the third vibrator 35 executes a vibration operation as a second notification operation (incoming call operation). Furthermore, when a call button (not shown) provided on the device 30 is operated after the incoming call, the third vibrator 35 stops vibrating, and the call application is activated, and the device 30 is in a call-enabled state in which it can make a call with another communication terminal under the control of the call control unit 313. When the device 30 is in a call-enabled state, a voice uttered by the user US is input to the microphone 37 controlled by the call control unit 313, and audio data based on this voice is wirelessly transmitted from the wireless communication I / F 31E to the communication terminal via the server 20. When in a call-enabled state, for example, voice data based on a voice uttered by a parent is transmitted from the mobile terminal 40 to the device 30 (wireless communication I / F 31E) via the server 20, and the speaker 36 controlled by the call control unit 313 outputs a voice based on this voice data. When a disconnection processing button (not shown) provided on the device 30 in a call-enabled state or a disconnection processing button of a communication terminal in a call state with the device 30 is operated, the device 30 becomes in a call-disabled state under the control of the call control unit 313.

[0050] The vibrator control unit 314 vibrates the first vibrator 33 when a safety condition (first condition) is met for the designated safety area. The first vibrator 33 does not vibrate when the safety condition is not met for the designated safety area. Furthermore, the vibrator control unit 314 vibrates the second vibrator 34 when an evacuation condition (first condition) is met for the designated evacuation area. The second vibrator 34 does not vibrate when the evacuation condition is not met for the designated evacuation area. Furthermore, the vibrator control unit 314 vibrates the third vibrator 35 when the second condition is met. The third vibrator 35 does not vibrate when the second condition is not met.

[0051] When the first condition and the second condition are simultaneously satisfied, the vibrator control unit 314 determines whether to give priority to the operation of the first vibrator 33 or the second vibrator 34, or the operation of the third vibrator 35.

[0052] When the safety condition and the second condition for the designated safety area are simultaneously satisfied, the vibrator control unit 314 prioritizes the operation of the first vibrator 33 over the operation of the third vibrator 35 and the operation of the speaker 36 and the microphone 37 for a call using SIP. That is, in this case, the vibrator control unit 314 operates the first vibrator 33 before the third vibrator 35 vibrates and the device 30 becomes a call-enabled state. In other words, while the first vibrator 33 is operating, the third vibrator 35 does not vibrate and the device 30 does not become a call-enabled state. When the operation of the first vibrator 33 ends, the third vibrator 35 vibrates and the device 30 becomes a call-enabled state. Also, if the safety condition is satisfied while the third vibrator 35 is vibrating or the device 30 is in a call-enabled state, the vibration of the third vibrator 35 is prohibited and the device 30 becomes a call-disabled state, and the first vibrator 33 operates instead.

[0053] When the evacuation condition and the second condition for the evacuation designated area are satisfied at the same time, the vibrator control unit 314 prioritizes the operation of the third vibrator 35 and the operation of the speaker 36 and the microphone 37 for a call using SIP over the operation of the second vibrator 34. That is, in this case, before the vibrator control unit 314 operates the second vibrator 34, the third vibrator 35 vibrates and the call control unit 313 puts the device 30 into a call-enabled state. In other words, when the third vibrator 35 is vibrating or the device 30 is in a call-enabled state, the second vibrator 34 does not operate. Also, when the third vibrator 35 stops vibrating and the device 30 is in a call-disabled state, the second vibrator 34 operates. Also, when the evacuation condition is satisfied while the second vibrator 34 is operating, the second vibrator 34 stops, the third vibrator 35 vibrates, and the device 30 is in a call-enabled state.

[0054] 1, the mobile terminal 40 held by a parent (not shown) of the user US has a display 41, a speaker 42, and a microphone 43. A touch panel is provided on the display 41. The mobile terminal 40 is, for example, a smartphone or a tablet computer.

[0055] 3, the mobile terminal 40 has the same hardware configuration as the server 20. That is, the mobile terminal 40 has, as the hardware configuration, a CPU 41A, a ROM 41B, a RAM 41C, a storage 41D, a wireless communication I / F 41E, an input / output I / F 41G, and an internal bus 41Z. For example, a walking attention calling application is installed in the ROM 41B. The display 41, the speaker 42, and the microphone 43 are connected to the input / output I / F 41G. The map data 22 and the designated area list 25 are recorded in the storage 41D.

[0056] 8 is a block diagram showing an example of the functional configuration of the mobile terminal 40. The functional configuration of the mobile terminal 40 includes a transmission / reception control unit 421, a display control unit 422, an input control unit 423, and a call control unit 424. These functions are realized by the CPU 41A reading and executing a program stored in the ROM 41B.

[0057] The transmission / reception control unit 421 controls the wireless communication I / F 41E. The wireless communication I / F 41E controlled by the transmission / reception control unit 421 is capable of wireless communication with the server 20 and the device 30 via the network.

[0058] The display control unit 422 controls the display 41. That is, the display control unit 422 causes, for example, information received by the wireless communication I / F 41E and information input via a touch panel to be displayed on the display 41. Furthermore, the display control unit 422 can display the map data 22 and the designated area list 25 on the display 41 when a walking attention calling application is activated.

[0059] The input control unit 423 can update the designated area list 25 recorded in the storage 41D based on information input to the mobile terminal 40 via the touch panel. For example, when a parent of the user US, looking at the map data 22 and the designated area list 25 displayed on the display 41, inputs information on the designated area and area type using the touch panel, the input control unit 423 updates the information on the designated area and area type in the designated area list 25. Furthermore, every time the designated area and area type are updated, the wireless communication I / F 41E wirelessly transmits update information, which is information on the updated designated area and area type, to the server 20.

[0060] The call control unit 424 controls the speaker 42 and the microphone 43 in the same manner as the call control unit 313. That is, regardless of whether the call application installed in the ROM 41B is activated, when a call button (not shown) provided on the mobile terminal 40 is operated after the mobile terminal 40 receives a call from a communication terminal (e.g., the device 30) other than the mobile terminal 40, the call application is activated, and the mobile terminal 40 is placed in a call-enabled state in which it can make a call with another communication terminal under the control of the call control unit 424. Also, when a disconnection processing button (not shown) provided on the mobile terminal 40 in a call-enabled state or a disconnection processing button of a communication terminal in a call state with the mobile terminal 40 is operated, the mobile terminal 40 is placed in a call-disabled state under the control of the call control unit 424.

[0061] Next, the operation and effect of the embodiment will be described with reference to the flowcharts of Figures 9 to 11. In the following description, the processes of the flowcharts are executed by one CPU, but multiple CPUs may execute the processes of each flowchart. Note that, before each process is executed, the contents of the designated area list 25 recorded in the server 20 and the mobile terminal 40 are the same.

[0062] First, the process performed by the CPU 41A of the mobile terminal 40 will be described with reference to the flowchart of Fig. 9. The CPU 41A repeatedly executes the process of the flowchart of Fig. 9 every time a predetermined time elapses.

[0063] First, in step S10 (hereinafter, the word "step" will be omitted), the CPU 41A determines whether or not update information regarding the designated region list 25 has been input using the display 41 (touch panel).

[0064] If the CPU 41A determines "Yes" in S10, the process proceeds to S11, where it updates the designated area list 25 recorded in the storage 41D and transmits the updated information to the server 20.

[0065] After completing the process of S11, the CPU 41A proceeds to S12 and determines whether the mobile terminal 40 is in a call-enabled state.

[0066] If the result of the determination in S12 is Yes, the CPU 41A proceeds to S13, where it controls the speaker 42 and the microphone 43.

[0067] When the process of S13 is completed or when the result of S12 is No, the CPU 41A temporarily ends the process of the flowchart in FIG.

[0068] Next, a process performed by the CPU 21A of the server 20 will be described with reference to the flowchart of Fig. 10. The CPU 21A repeatedly executes the process of the flowchart of Fig. 10 every time a predetermined time elapses.

[0069] First, in S20, the CPU 21A determines whether update information has been received from the mobile terminal 40 or not.

[0070] If the CPU 21A determines "Yes" in S20, the process proceeds to S21, where it updates the designated area list 25 recorded in the ROM 21B.

[0071] When the result of the determination in S20 is No or when the process of S21 is completed, the CPU 21A proceeds to S22 and transmits the latest update information to the device 30 by wireless.

[0072] After completing the process of S22, the CPU 21A proceeds to S23, where it determines whether or not voice data has been received from at least one of the device 30 and the mobile terminal 40.

[0073] If the result of the determination in S23 is Yes, the CPU 21A proceeds to S24 and transfers the received voice data to the device 30 or the mobile terminal 40.

[0074] When the process of S24 is completed or when the result of S23 is No, the CPU 21A temporarily ends the process of the flowchart in FIG.

[0075] Next, a process performed by the CPU 31A of the device 30 will be described with reference to the flowchart of Fig. 11. The CPU 31A repeatedly executes the process of the flowchart of Fig. 11 every time a predetermined time elapses. Note that the device 30 receives the latest update information from the server 20 every time the predetermined time elapses.

[0076] First, in S30, the CPU 31A determines whether or not there is an incoming call using SIP.

[0077] If the CPU 31A judges Yes in S30, it proceeds to S31 and judges whether the designated area closest to the device 30 is a safe designated area based on the position information (update information) of each designated area and the position information of the device 30 (position information based on GPS).

[0078] If the CPU 31A determines "Yes" in S31, the process proceeds to S32, where it determines whether or not the distance D from the device 30 to the designated safety area is equal to or less than a first threshold value.

[0079] If the CPU 31A judges "Yes" in S32, the process proceeds to S33. In this case, the user US (device 30) is located in or near the designated safety area. At this time, the first vibrator 33 controlled by the CPU 31A vibrates. Therefore, the user US recognizes that many traffic accidents have occurred in the past in the area where the user US is located or in the vicinity thereof, and that it is necessary to perform a visual vehicle monitoring action. Furthermore, when the CPU 31A judges "Yes" in S32, the safety condition is established.

[0080] After completing the process of S33, the CPU 31A proceeds to S34, where it determines whether or not the distance D is greater than the first threshold value. That is, the CPU 31A determines whether or not the user US has left the designated safety area.

[0081] If the result of S34 is Yes, the CPU 31A proceeds to S35, where it stops the first vibrator 33.

[0082] After completing the process of S35, the CPU 31A proceeds to S36 and determines whether or not there is an incoming call.

[0083] If the CPU 31A determines "Yes" in S36, the process proceeds to S37, where it causes the third vibrator 35 to vibrate.

[0084] After completing the process of S37, the CPU 31A proceeds to S38 and determines whether or not the call button has been operated.

[0085] If the CPU 31A determines "Yes" in S38, the process proceeds to S39, where it stops the operation of the third vibrator 35 and switches the device 30 to a call-enabled state. Thus, the user US and the parent can use the device 30 and the mobile terminal 40 to talk on the phone.

[0086] After completing the process of S39, the CPU 31A proceeds to S40 and determines whether or not a disconnection process has been executed. When the disconnection process button of at least one of the device 30 and the mobile terminal 40 is operated, the CPU 31A determines Yes in S40.

[0087] If the CPU 31A determines "Yes" in S40, the process proceeds to S41, where it switches the device 30 to a call-disabled state.

[0088] On the other hand, if the CPU 31A judges No in S31 and S32, the process proceeds to S42. That is, the CPU 31A vibrates the third vibrator 35 regardless of whether the distance D from the device 30 to the designated evacuation area is equal to or less than the second threshold. Note that the evacuation condition is met when the distance D is equal to or less than the second threshold.

[0089] Thereafter, the CPU 31A executes the processes of S43, 44, 45, and 46. The processes of S42, 43, 44, 45, and 46 are the same as the processes of S37, 38, 39, 40, and 41, respectively.

[0090] After completing the process of S46, the CPU 31A proceeds to S47 and determines whether or not the distance D from the device 30 to the designated save area is equal to or less than a second threshold value.

[0091] If the CPU 31A judges Yes in S47, the process proceeds to S48. In this case, the user US (device 30) is located in the designated evacuation area or in the vicinity of the designated evacuation area. At this time, the second vibrator 34 controlled by the CPU 31A vibrates. Therefore, the user US recognizes that a suspicious person has been spotted in the area where the user US is located in the past and that the user US needs to evacuate from this area immediately. Furthermore, if the CPU 31A judges Yes in S47, the evacuation condition is established.

[0092] After completing the process of S48, the CPU 31A proceeds to S49, where it determines whether or not the distance D is greater than the second threshold value, that is, the CPU 31A determines whether or not the user US has left the designated save area.

[0093] If the result of S49 is Yes, the CPU 31A proceeds to S50 and stops the second vibrator .

[0094] If the CPU 31A determines No in S30, the process proceeds to S51, and the same process as S31 is executed.

[0095] If the CPU 31A determines Yes in S51, it then executes the processes of S52, 53, 54, and 55. The processes of S52, 53, 54, and 55 are the same as the processes of S32, 33, 34, and 35, respectively.

[0096] On the other hand, if the CPU 31A determines No in S51, it executes the processes of S56, 57, 58, and 59. The processes of S56, 57, 58, and 59 are the same as the processes of S47, 48, 49, and 50, respectively.

[0097] When the processes of S41, S50, S55, and S59 have been completed, or when the determinations of S47, S52, and S46 are No, the CPU 31A temporarily ends the process of the flowchart in FIG.

[0098] As described above, in the embodiment, the first vibrator 33 vibrates when the user US is located in or near the designated safety area. Therefore, the user US can recognize that many traffic accidents have occurred in the area in which the user US is located, and that it is necessary to perform safety confirmation actions. Furthermore, the second vibrator 34 vibrates when the user US is located in or near the designated evacuation area. Therefore, the user US can recognize that a suspicious person has been spotted in the area in which the user US is located, and that it is necessary to perform evacuation actions.

[0099] Moreover, the user US can recognize which of the first vibrator 33 and the second vibrator 34 is vibrating. Therefore, the user US can recognize whether to perform a safety confirmation action or an evacuation action.

[0100] Furthermore, in this embodiment, when the first condition and the second condition are met simultaneously, a special control is executed in the device 30.

[0101] That is, when the first condition, which is a safety condition, and the second condition are simultaneously satisfied, the first vibrator 33 is operated in priority to the third vibrator 35. Therefore, when the safety condition and the second condition are simultaneously satisfied, the user US who recognizes the vibration generated by the first vibrator 33 recognizes the need to perform a safety confirmation action. That is, there is little risk that the vibration of the third vibrator 35 will direct the attention of the user US away from the safety confirmation action and toward a call action via the device 30.

[0102] Furthermore, when the first condition, which is the evacuation condition, and the second condition are simultaneously satisfied, the third vibrator 35 of the device 30 is operated in priority over the second vibrator 34. This allows the user US to recognize that the device 30 has received an incoming call. This allows the user US to talk to a parent, for example, via the device 30 and the mobile terminal 40. This allows the parent to convey a necessary message to the user US, for example. This message is a message urging the user US not to pass through the designated evacuation area, or a message urging the user US to evacuate from the designated evacuation area.

[0103] Furthermore, at this time, the third vibrator 35 vibrates, and the user US is in a state where he or she can talk. That is, people around the user US recognize that the user US is in a state where he or she can talk to someone via the device 30. Therefore, for example, when the user US is in the fifth road 22-5, which is the designated evacuation area, it becomes difficult for others on the fifth road 22-5 to perform actions that cause disadvantage to the user US.

[0104] Furthermore, when the call is disconnected, the second vibrator 34 vibrates. Therefore, the user US can quickly escape from the escape designated area.

[0105] The system 10, the server 20, and the device 30 according to the embodiment have been described above, but the design of these can be modified as appropriate without departing from the spirit and scope of the present invention.

[0106] For example, when the save condition and the second condition are met at the same time, the second vibrator 34 may be operated in preference to the third vibrator 35 of the device 30.

[0107] The device 30 may have a function of sending and receiving mail, an alarm function that is activated at a predetermined set time, and a function of displaying various images on the display 41. The mail includes, for example, e-mail and SMS (short message). These functions are realized, for example, by an application installed in the ROM 31B and the CPU 31A. In this case, the second notification operation of the device 30 may be at least one of a vibration operation performed by the third vibrator 35 when a mail is received, an alarm sound output operation performed by the speaker 36, and an operation of displaying a pop-up image on the display 41.

[0108] When the wireless communication I / F 31E receives update information from the server 20, the received update information may be recorded in ROM 31B or storage 31D. In this case, the frequency with which the device 30 receives update information from the server 20 may be lower than the reception frequency in the embodiment. Also, the wireless communication I / F 31E may receive the latest designated area list 25 from the server 20, and the received designated area list 25 may be recorded in ROM 31B or storage 31D.

[0109] The system 10 does not need to include the server 20. In this case, the designated area list 25 is recorded in the ROM 31B or storage 31D of the device 30.

[0110] The wireless communication I / F 31E of the device 30 may wirelessly transmit location information of the device 30 to the mobile terminal 40. In this way, a parent looking at the display 41 of the mobile terminal 40 can recognize the current location of the user US.

[0111] The device 30 may include only one notification device. For example, one vibrator (notification device) may vibrate in different modes when a safety condition is satisfied, when an evacuation condition is satisfied, and when a second condition is satisfied.

[0112] Alternatively, the device 30 may have only one notification device, which may be the speaker 36. For example, when it is determined that the first condition is satisfied, the speaker 36 may execute a voice output operation to alert the user US as the first notification operation. For example, when the safety condition is satisfied, the speaker 36 may output a voice message saying "Watch out for surrounding vehicles." When the evacuation condition is satisfied, the speaker 36 may output a voice message saying "Evacuate from this area as soon as possible." Furthermore, when it is determined that the second condition is satisfied, the speaker 36 may output a ring tone to call the user US.

[0113] A single vibrator may vibrate in different manners when a safety condition is met or when an evacuation condition is met, or the vibrator may vibrate in the same manner when a safety condition is met or when an evacuation condition is met.

[0114] The device 30 may be attached to something other than the school bag SB. For example, the device 30 may be attached to a hat on the head of the user US or to clothing worn by the user US.

[0115] A mobile terminal may be used as the device 30. The mobile terminal may include, for example, a smartphone.
