<Traffic safety system>
FIG. 1 is a block diagram schematically showing the overall configuration of a traffic safety system ES1 in an embodiment of the present invention. As shown in FIG. 1, the traffic safety system ES1 of this embodiment includes a plurality of child terminals 1, a plurality of parent terminals 2, and a server 3 (remote device). The child terminal 1, the parent terminal 2, and the server 3 are interconnected via a network N. Network N is, for example, a mobile communication network. The mobile communication network is, for example, a fourth generation mobile communication network or a fifth generation mobile communication network. Note that the network N includes a base station and the like.

The number of child terminals 1 included in the traffic safety system ES1 is not particularly limited as long as it is plural. However, for convenience of explanation, in the following explanation, an example in which the number of child terminals 1 included in the traffic safety system ES1 is two will be described. Among these child terminals 1, one child terminal 1 is referred to as a first child terminal 1A. Further, among these child terminals 1, the other child terminal 1 is referred to as a second child terminal 1B.

Further, the number of parent terminals 2 included in the traffic safety system ES1 is not particularly limited. However, for convenience of explanation, in the following explanation, an example in which the number of parent terminals 2 included in the traffic safety system ES1 is two will be described. Among these parent terminals 2, one parent terminal 2 is referred to as a first parent terminal 2A. Furthermore, among these parent terminals 2, the other parent terminal 2 is referred to as a second parent terminal 2B.

For example, the first child terminal 1A and the second child terminal 1B are carried by different children (movers). At this time, for example, the first parent terminal 2A is owned by the guardian of the child who carries the first child terminal 1A. Further, for example, the second parent terminal 2B is owned by a guardian of a child who carries the second child terminal 1B. However, the person carrying the child terminal 1 is not limited to a child, and may be an elderly person or the like. Furthermore, the person who has the parent terminal 2 is not limited to a guardian, but may also be a school staff member or the like. In addition, in this embodiment, the first child terminal 1A and the second child terminal 1B are carried by the child. Moreover, in this embodiment, the first parent terminal 2A is owned by the guardian of the child who carries the first child terminal 1A. Furthermore, in this embodiment, the second parent terminal 2B is owned by the guardian of the child who carries the second child terminal 1B.

The first child terminal 1A, the second child terminal 1B, the first parent terminal 2A, and the second parent terminal 2B can communicate with each other. That is, the first child terminal 1A can communicate with the second child terminal 1B, the first parent terminal 2A, and the second parent terminal 2B. Further, the second child terminal 1B can communicate with the first child terminal 1A, the first parent terminal 2A, and the second parent terminal 2B. Further, the first parent terminal 2A can communicate with the first child terminal 1A, the second child terminal 1B, and the second parent terminal 2B. Further, the second parent terminal 2B can communicate with the first child terminal 1A, the second child terminal 1B, and the first parent terminal 2A. Here, communicable includes that the terminals can communicate directly with each other via the network N, and that the terminals can communicate with each other via the network N and the server 3. Furthermore, being communicable also includes terminals communicating with each other without going through the network N using short-range wireless communication or the like.

The child terminal 1 is a robot equipped with a communication function, and is used by being attached to, for example, the shoulder belt of a school bag. The child terminal 1 is carried by a moving person (a child in this embodiment). For example, the child terminal 1 is carried by a child who goes to and from school. The child terminal 1 transmits various information (for example, an emergency signal indicating an emergency situation) to the server 3 via the network N. The child terminal 1 transmits various information transmitted by the server 3 (for example, child terminal photographing request information based on an instruction from the parent terminal 2, emergency response information generated by the server 3 based on an emergency signal) via the network N. and receive it. Note that a more detailed configuration of the child terminal 1 will be described later.

The parent terminal 2 is, for example, a smartphone, a tablet, a smart watch, or the like. The parent terminal 2 transmits various information according to the instructions input to the parent terminal 2 to the server 3 via the network N. The information transmitted from the parent terminal 2 to the server 3 includes, for example, an instruction signal for generating the child terminal photographing request information described above. The parent terminal 2 receives various information transmitted from the server 3 via the network N. Examples of the information transmitted from the server 3 to the parent terminal 2 include emergency response information generated by the server 3 based on the above-mentioned emergency signal. Note that a more detailed configuration of the parent terminal 2 will be described later.

The server 3 associates the child terminal 1 and the parent terminal 2 and generates emergency response information to be transmitted to the child terminal 1 and the parent terminal 2 based on the emergency signal transmitted from the child terminal 1. Further, the server 3 generates an instruction signal (eg, normal time child terminal photography request information) to be sent to the child terminal 1 based on the instruction sent from the parent terminal 2.

In addition, the server 3 generates, for example, the movement trajectory of the child carrying the child terminal 1 using the location information and map information transmitted from the child terminal 1, and generates information that combines the movement trajectory with the map information. may be generated as child terminal position information. The server 3 also controls the child terminal 1 based on the operation determination information sent from the child terminal 1 (information that determines whether a predetermined action has been performed at the setting position set in the child terminal 1). The motion of the person carrying the device may be evaluated, and motion evaluation information indicating the evaluation result may be generated. In this case, the server 3 transmits the generated child terminal position information and operation evaluation information to the parent terminal 2.

The server 3 includes a communication section 31, a control section 32, and a storage section 33. The communication unit 31 receives various information (for example, an emergency signal) transmitted from the child terminal 1 via the network N, and outputs it to the control unit 32. The communication unit 31 receives various information (for example, instruction signals) transmitted from the parent terminal 2 via the network, and outputs it to the control unit 32. The communication unit 31 transmits information output from the control unit 32 (for example, emergency response information and normal time child terminal photography request information) to both or either of the child terminal 1 and the parent terminal 2 via the network N. do.

The control unit 32 includes a normal information generation unit 32a (generation unit) and an emergency information generation unit 32b (generation unit), and centrally controls the operation of the server 3. The control unit 32 functions as a processing unit that processes information acquired by the child terminal 1. However, all or part of the functions of the processing section may be provided by the control section 20 (described later) of the child terminal 1 or the control section 48 (described later) of the parent terminal 2.

The normal information generation unit 32a transmits information to the child terminal 1 and the parent terminal 2 based on information output from the communication unit 31 when the child terminal 1 is in a normal state (a state in which the operation button 19 described later is not operated). Generate various types of information. The emergency information generation unit 32b generates various information to be transmitted to the child terminal 1 and the parent terminal 2 based on the information output from the communication unit 31 when the child terminal 1 is in an emergency state (the operation button 19 is operated). (e.g., emergency response information).

The control unit 32 causes the storage unit 33 to store information output from the communication unit 31 (various information received from the child terminal 1 and the parent terminal 2). Further, the control unit 32 performs control or processing according to the instruction of the instruction signal received from the parent terminal 2. For example, if the above instruction is an instruction to request the child terminal 1 to take a photograph, the control unit 32 generates normal time child terminal photographing request information in the normal time information generation unit 32a, and controls the communication unit 31. Then, the child terminal 1 is caused to transmit the child terminal photographing request information. Note that the normal child terminal photographing request information (fifth information) is child terminal photographing request information to be described later that is generated in the normal state.

Further, when the control unit 32 receives an emergency signal from the child terminal 1, the emergency information generation unit 32b generates emergency response information, controls the communication unit 31, and transmits the emergency response information to the child terminal 1 and the emergency response information. Either or both of the parent terminals 2 are made to transmit. The emergency response information generated by the emergency information generation unit 32b includes, for example, operation restriction information (first information), other child terminal photography request information (second information), emergency notification information (third information), and other child terminals. They are photography transfer information (fourth information), emergency child terminal photography request information (fifth information), report selection information (sixth information), and lighting information.

The operation restriction information is information for restricting the operation of the radar 12 of the child terminal 1, which will be described later. The child terminal 1 limits the operation of the radar 12 when the operation restriction information is input. The term "restriction" here means to restrict the operation more than usual, and includes, for example, reducing the number of operations and stopping the operation. Further, the operation restriction information may include information that restricts processing in other normal states.

Other child terminal photography request information is sent to another child terminal 1 (for example, second child terminal 1B) that is provided to be able to communicate with the child terminal 1 (for example, first child terminal 1A) to which the emergency signal was output. , is information for requesting that a camera 18, which will be described later, be provided in another child terminal 1 to take a picture. When the other child terminal photography request information is input, the child terminal 1 uses the camera 18 to take a picture.

The emergency situation notification information is information for notifying the parent terminal 2, which is provided so as to be able to communicate with the child terminal 1 to which the emergency signal has been output, that an emergency situation has occurred to the child. Note that the emergency notification information is transmitted to the parent terminal 2 (for example, the first parent terminal 2A) linked to the child terminal 1 (for example, the first child terminal 1A) to which the emergency signal was output. The parent terminal 2 to which the emergency notification information has been input displays, for example, information indicating that an emergency signal has been output from the child terminal 1 on the display unit 42, which will be described later.

The other child terminal photographing transfer information includes a parent terminal 2 (e.g., Information for transmitting photographic information obtained by the above-mentioned different child terminal 1 (for example, the second child terminal 1B) taking a photograph with the camera 18 (photographing unit) to the first parent terminal 2A). be. The child terminal 1 to which the child terminal photographing transfer information has been input outputs the photographing information to the server 3. The photographing information is transferred to the parent terminal 2 via the server 3, for example.

The emergency child terminal photographing request information is child terminal photographing request information generated in an emergency state. The child terminal photographing request information is information for requesting photographing using the camera 18 (another photographing unit) provided in the child terminal 1. The child terminal photographing request information is input to the child terminal 1 to which an emergency signal has been output, or to the child terminal 1 in a normal state that is not outputting an emergency signal. The child terminal 1 to which the child terminal photographing request information has been input takes a photograph using the camera 18.

The report selection information is information for displaying on the display unit 42 (described later) a selection as to whether the parent terminal 2 should make an emergency report to the police agency. For example, the report selection information is output to the parent terminal 2 (for example, the first parent terminal 2A) that is linked to the child terminal 1 (for example, the first child terminal 1A) to which the emergency signal was output. On the parent terminal 2 to which the report selection state has been input, a pop-up message asking whether to report to the police agency is displayed on the display unit 42, for example.

The lighting information is information for lighting the light 14 on the child terminal 1 to which the emergency signal has been output. For example, the child terminal 1 to which the lighting information has been input turns on the light 14. By lighting the light 14, the front of the child terminal 1 is illuminated, making it easier for others to notice the child's presence and giving the child a sense of security.

In this embodiment, the emergency response information generated by the emergency information generation unit 32b includes the above-mentioned operation restriction information, other child terminal photography request information, emergency notification information, other child terminal photography transfer information, and emergency child terminal photography request information. This includes all of the terminal photographing request information, report selection information, and lighting information. However, the emergency response information generated by the emergency information generation unit 32b does not necessarily have to be all of the above, and is at least any of the operation restriction information, other child terminal photographing request information, and emergency situation notification information.

In addition, the control unit 32 is configured such that a first current location, which is the current location of the child terminal 1 to which the emergency signal has been output, and a second current location, which is the current location of the other child terminal 1, have a predetermined geographical relationship. Determine if it is. The emergency information generation unit 32b generates other child terminal photographing request information for other child terminals 1 that have a predetermined geographical relationship with the child terminal 1 to which the emergency signal has been output. In other words, the control unit 32 causes another child terminal 1 (for example, the second child terminal 1B) that has a predetermined geographical relationship with the child terminal 1 (for example, the first child terminal 1A) to which the emergency signal was output to take a picture. . Here, being in a predetermined geographical relationship means, for example, that the child terminals 1 are located within a predetermined distance from each other.

Furthermore, the control unit 32 associates the child terminal 1 carried by the child with the parent terminal 2 carried by the guardian and stores them in the storage unit 33 based on the telephone number or identification information. Thereby, the server 3 performs processing on a plurality of sets (two sets in this embodiment) of child terminals 1 and parent terminals 2.

The storage unit 33 stores various information received from the child terminal 1 and the parent terminal 2. The storage unit 33 also stores map information. Note that the map information includes, for example, a map that includes a commuting route from home to school. Furthermore, the map information includes information such as the route network (junctions, branches) of sidewalks and roads.

Furthermore, the storage unit 33 stores part or all of the information processing program P. The information processing program P is a program that causes the computer to execute a position detection step (step S11 described later), an object detection step (step S21 described later), and an emergency response information generation step (step S52 described later). The position detection step is a step of detecting the current position of the child terminal 1 carried by the child. The object detection step is a step of detecting objects around the child terminal 1 carried by the child. The emergency response information generation step is a step of generating emergency response information when a child has an emergency situation and a button is operated by the child.

Server 3 includes a computer. The communication unit 31, control unit 32, and storage unit 33 included in the server 3 are realized, for example, by a hardware processor such as a CPU (Central Processing Unit) executing a program (software). Some or all of these components are hardware (circuit parts) such as LSI (Large Scale Integration), ASIC (Application Specific Integrated Circuit), FPGA (Field-Programmable Gate Array), and GPU (Graphics Processing Unit). (including circuitry), or may be realized by collaboration between software and hardware. The program may be stored in advance in a storage device (a storage device with a non-transitory storage medium) such as an HDD (Hard Disk Drive) or flash memory, or may be stored in a removable storage device such as a DVD or CD-ROM. It is stored in a medium (non-transitory storage medium), and may be installed by loading the storage medium into a drive device. The information processing program P causes such a server 3 to execute, for example, an emergency response information generation step.

<Child terminal>
FIG. 2 is a block diagram schematically showing the main configuration of the child terminal 1 in this embodiment. As shown in FIG. 2, the child terminal 1 includes a position acquisition unit 11 (position detection unit), a radar 12 (object detection unit), an acceleration sensor 13, a light 14 (lighting unit), a microphone 15, a speaker 16 (notification unit), It includes a vibrator 17 (notification section), a camera 18 (photographing section, other photographing section), an operation button 19 (operation section, permission operation section), a control section 20, a communication section 21, and a memory 22.

The position acquisition unit 11 acquires position information of the child terminal 1. The position information of the child terminal 1 is the current position of the child terminal 1. That is, the position acquisition unit 11 detects the current position of the child terminal 1. The position acquisition unit 11 includes, for example, a positioning signal receiving antenna that receives a positioning signal from a satellite or the like, and outputs the received positioning signal to the control unit 20. Note that the child terminal 1 may acquire information indicating the current location based on communication with a base station, for example.

Radar 12 detects objects around child terminal 1 . In this embodiment, the radar 12 detects objects behind the child terminal 1, for example. The radar 12 is, for example, a millimeter wave radar. The radar 12 outputs, to the control unit 20, detection signals related to, for example, the distance, relative velocity, relative position, and direction to an external object.

The acceleration sensor 13 detects acceleration acting on the child terminal 1 and outputs a signal of the detected acceleration to the control unit 20. Specifically, the acceleration sensor 13 detects the acceleration of the child terminal 1 in three directions: the X axis, the Y axis, and the Z axis, and outputs signals of the detected acceleration in the three directions to the control unit 20.

The light 14 operates under the control of the control unit 20. The light 14 includes, for example, an LED (light emitting diode) that emits light in three colors: red, green, and blue. The light 14 has an illuminance that allows children to recognize their surroundings, for example, in the evening or at night. It is possible to arbitrarily set the color in which the light 14 is made to emit light and the light emission pattern in which the light 14 is made to emit light. For example, the light 14 may turn on in white so as to illuminate the surroundings when normal Tokiko terminal photography request information is input. Further, when the operation button 19 is operated in an emergency situation, the light 14 may be turned on so as to flash in red so that those around the user can easily recognize that there is an emergency situation. In this embodiment, the light 14 lights up at least when the operation button 19 is operated. Note that the light 14 may be, for example, a liquid crystal device, an organic EL (electroluminescence) device, or the like.

The microphone 15 outputs a signal (for example, an audio signal, etc.) obtained by collecting sound to the control unit 20 . Note that the microphone 15 may be a microphone array composed of a plurality of microphones. The speaker 16 converts a signal (for example, an audio signal, etc.) output by the control unit 20 into sound. The vibrator 17 is a vibrator, and generates vibrations according to the notification information output by the control unit 20.

The camera 18 photographs the surroundings of the child terminal 1. The shooting here may be shooting a moving image or a still image. In other words, the photographic information acquired by the camera 18 may be either a moving image or a still image. In this embodiment, the camera 18 photographs the front area around the child terminal 1. However, the camera 18 may also take pictures of the rear area around the child terminal 1. Further, a plurality of cameras 18 may be provided to take images in different directions. The camera 18 photographs the surrounding situation of the child terminal 1 and outputs photographing information to the control unit 20.

The operation button 19 is a physical button operated by a child carrying the child terminal 1. For example, the operation button 19 is provided in a part of the housing of the child terminal 1 in an exposed state. When the operation button 19 is operated by a child, it outputs a signal (operation signal) indicating that it has been operated to the control unit 20.

The operation button 19 is operated when the child feels that there is an emergency situation. In other words, the operation button 19 functions as an operation unit that is operated by the traveler when an emergency situation arises for the traveler. The operation button 19 is operated when normal child terminal photographing request information is input to the child terminal 1 from the parent terminal 2 and the child permits photographing by the camera 18. In other words, the operation button 19 functions as a permission operation section for the traveler to indicate his/her intention to permit photography. Such an operation button 19 is a single physical operation section that has the functions of the above-mentioned operation section and the above-mentioned permission operation section.

For example, when normal child terminal photography request information based on an instruction from the parent terminal 2 is input to the child terminal 1 and the child permits photography using the camera 18, the speaker 16 asks whether or not photography is permitted. Audio is output. Therefore, the operation signal output from the operation button 19 after such a sound is output is treated as a photographing permission signal indicating that photographing is permitted. On the other hand, if the child feels that there is an emergency situation, the operation button 19 is operated while the above-mentioned sound is not being output. Therefore, an operation signal output from the operation button 19 in a state where no sound is output is treated as an emergency signal indicating an emergency situation.

The control unit 20 centrally controls the operation of the child terminal 1. The control unit 20 acquires the positioning information output by the position acquisition unit 11, the detection signal output by the radar 12, the detection value output by the acceleration sensor 13, and the audio signal output by the microphone 15. The control unit 20 controls the communication unit 21 to obtain position information based on the positioning information acquired from the position acquisition unit 11, a detection signal acquired from the radar 12, a detection value acquired from the acceleration sensor 13, and a detection value acquired from the microphone 15. Send the audio signal to the server 3.

The control section 20 includes a position determination section 20a, a vehicle detection section 20b, a photographing control section 20c, a radar stop section 20d, and an emergency communication control section 20e. For example, the position determination unit 20a uses the set position information stored in the memory 22 and the position information based on the positioning information acquired from the position acquisition unit 11 to determine the set position indicated by the set position information and the set position indicated by the position information. It is determined that there is a predetermined geographical relationship between the current location of the child terminal 1 and the current location of the child terminal 1. For example, the position determining unit 20a determines whether the distance between the current position of the child terminal 1 and the set position has become shorter than a predetermined distance (for example, a distance of about several meters).

The control unit 20 outputs notification information and causes the vibrator 17 to vibrate when the position determination unit 20a determines that the distance between the current position of the child terminal 1 and the set position has become shorter than a predetermined distance. In such a case, the purpose of vibrating the vibrator 17 is to notify the child terminal 1 that it is approaching a set position (a set position that is a geographical position set in advance so that a predetermined action can be performed by the person carrying the child terminal 1). This is to make people who carry 1 aware of this.

The vehicle detection unit 20b uses a well-known recognition method to determine whether a person or a vehicle is included from the detection signal obtained from the radar 12. When the control unit 20 determines that a vehicle is included in the detection signal, the control unit 20 outputs notification information to vibrate the vibrator 17, or causes the light 14 to emit light, to make the child terminal 1 portable. inform children of the approaching vehicle. In addition, when the vehicle detection part 20b vibrates the vibrator 17, it may change the vibration interval or the intensity of vibration according to the content to be notified.

In addition, the vehicle detection unit 20b detects a vehicle approaching the child terminal 1 (i.e., child), or when the distance from the child terminal 1 (i.e., child) to the vehicle is less than a predetermined distance (e.g., 10 m or less). If it is determined that the child is present, warning information is generated to notify the vehicle of the child's presence. The vehicle detection unit 20b outputs caution information from the communication unit 21 toward the vehicle. For example, when the vehicle receives the caution information from the child terminal 1, the vehicle notifies the driver of the presence of the child using a display section and a speaker provided in the vehicle. Based on the child presence information provided by the vehicle, the driver of the vehicle can pay attention to the presence of the child even if the child cannot be visually recognized.

The photographing control unit 20c controls the camera 18. The photographing control unit 20c causes the camera 18 to take a photograph when the operation button 19 is operated. For example, the photographing control section 20c causes the camera 18 to take a photograph when an emergency signal is input to the control section 20 from the operation button 19. Further, the photographing control section 20c causes the camera 18 to take a photograph when a photographing permission signal is input to the control section 20 from the operation button 19. When photographing information is input to the control section 20 from the camera 18, the photographing control section 20c causes the photographing information to be stored in the memory 22. Further, the photographing control section 20c causes the communication section 21 to transmit photographing information as necessary.

The radar stop unit 20d limits the operation of the radar 12 when the operation restriction information is input. By restricting the operation of the radar 12, output of notification information from the vehicle detection unit 20b is restricted. The operation restriction information is generated based on the emergency signal output from the operation button 19. That is, when an emergency signal is output from the operation button 19, the operation of the radar 12 is restricted and the vibration of the vibrator 17 is suppressed. In this manner, by suppressing normal state processing in an emergency state, it is possible to prevent children from becoming confused. Note that the operation restriction information, which is one type of emergency response information, can be generated, for example, by the emergency information generation unit 32b of the server 3, as described above. However, the operation restriction information may be generated by the control unit 20 of the child terminal 1, for example.

The emergency communication control unit 20e causes the communication unit 21 to transmit an emergency signal when an emergency signal is output from the operation button 19. As described above, the server 3 can generate emergency notification information, which is one type of emergency response information, based on the emergency signal output from the child terminal 1. However, the emergency notification information may be generated by the control unit 20 of the child terminal 1, for example.

The control unit 20 also acquires various information output by the communication unit 21. When the information output from the communication unit 21 is an audio signal, the control unit 20 outputs the audio signal to the speaker 16. When the information output from the communication unit 21 is a vibration signal, the control unit 20 outputs the information to the vibrator 17. Furthermore, when an emergency signal is output from the operation button 19, the control unit 20 turns on the light 14. Further, the control unit 20 turns on the light 14 when the normal terminal photographing request information is input. The control unit 20 controls, for example, the color of light emitted by the light 14 or the blinking state of the light 14 in accordance with information or the like.

Note that, for example, the control unit 20 includes a computer. A hardware processor such as a CPU executes a program (software) in the position determination unit 20a, vehicle detection unit 20b, photographing control unit 20c, radar stop unit 20d, and emergency communication control unit 20e included in the control unit 20. This may be realized by Some or all of these components may be realized by hardware (including circuit parts) such as LSI, ASIC, FPGA, GPU, etc., or may be realized by collaboration of software and hardware. . The program may be stored in advance in a storage device such as an HDD or a flash memory (a storage device equipped with a non-transitory storage medium), or a removable storage medium such as a DVD or CD-ROM (a non-transitory storage medium). The software may be installed by attaching the storage medium to a drive device.

The communication unit 21 includes, for example, a communication IC card, a communication antenna, and a communication module, and performs communication (wireless communication) under the control of the control unit 20. The communication unit 21 transmits the information output by the control unit 20 to the server 3 via the network N. The communication unit 21 receives the information transmitted by the server 3 and outputs the received information to the control unit 20.

The memory 22 stores various information and programs used by the child terminal 1. For example, the memory 22 stores setting position information sent from the server 3. Note that the setting position defined by this setting position information is set according to an operation input to the parent terminal 2. The memory 22 also stores programs that implement the functions of the control unit 20 (for example, the functions of the position determination unit 20a, vehicle detection unit 20b, photography control unit 20c, radar stop unit 20d, and emergency communication control unit 20e). .

Further, the memory 22 stores part or all of the information processing program P. The control unit 20 includes a computer as described above. The information processing program P causes such a control unit 20 to execute, for example, the above-described position detection step and object detection step.

FIG. 3 is a schematic diagram showing the layout of each component of the child terminal 1. As shown in FIG. As shown in FIG. 3, a light 14 and a camera 18 are located at the front of the child terminal 1. The light 14 illuminates the front of the child terminal 1 by being turned on. The camera 18 photographs the front of the child terminal 1. Furthermore, a radar 12 is located at the rear of the child terminal 1. Radar 12 detects objects behind child terminal 1 . For example, the radar 12 detects a vehicle approaching from behind the child.

The operation button 19 is located at the center of the child terminal 1 in the front-rear direction. That is, the operation button 19 is located between the camera 18 and the radar 12. By locating the operation button 19 in the center of the child terminal 1 in the front-rear direction, the operation button 19 can be easily recognized visually by the child.

Furthermore, the positions of the position acquisition section 11, acceleration sensor 13, microphone 15, speaker 16, vibrator 17, control section 20, communication section 21, and memory 22 are not particularly limited. For example, as shown in FIG. 3, the microphone 15, the speaker 16, the vibrator 17, and the communication unit 21 are located between the camera 18 and the radar 12 in the front-back direction. Further, although the CPU, etc., acceleration sensor 13, and memory 22 constituting the position acquisition unit 11 and the control unit 20 are omitted in FIG. .

<Parent terminal>
FIG. 4 is a block diagram schematically showing the main configuration of the parent terminal in this embodiment. As shown in FIG. 4, the parent terminal 2 includes an operation section 41, a display section 42, a microphone 43, a speaker 44, a vibrator 45, a communication section 46, a memory 47, and a control section 48.

The operation unit 41 is operated by a guardian who owns the parent terminal 2, and outputs a signal to the control unit 48 according to the guardian's operation. The operation unit 41 is, for example, a touch panel sensor provided on the display unit 42. The display unit 42 displays various information output by the control unit 48. The display unit 42 is, for example, a liquid crystal display device, an organic EL display device, an electronic ink display device, or the like.

The microphone 43 outputs a signal (for example, an audio signal, etc.) obtained by collecting sound to the control unit 48 . Note that the microphone 43 may be a microphone array composed of a plurality of microphones. The speaker 44 converts a signal (for example, an audio signal, etc.) output by the control unit 48 into sound. The vibrator 45 is a vibrator, and generates vibrations according to the notification information output by the control unit 48.

The communication unit 46 includes, for example, a communication IC card, a communication antenna, and a communication module, and performs communication (wireless communication) under the control of the control unit 48. The communication unit 46 transmits the information output by the control unit 48 to the server 3 via the network N. The communication unit 46 receives various information transmitted from the server 3 and outputs it to the control unit 48 . The memory 47 stores various information and programs used by the parent terminal 2.

The control unit 48 centrally controls the operation of the parent terminal 2. The control unit 48 acquires the signal output by the operation unit 41 and performs control or processing according to the acquired signal. For example, when emergency notification information is input via the network N, the control unit 48 causes the display unit 42 to display information indicating that the child terminal 1 is in an emergency situation. Further, when the report selection information is input via the network N, the control unit 48 causes the display unit 42 to display a pop-up asking whether to report to the police agency.

<Processing performed by traffic safety system ES1>
Next, the processing (traffic safety method, information processing method) performed by the traffic safety system ES1 according to this embodiment will be explained. In the following, first, a process for notifying a child carrying the child terminal 1 that the child is approaching a predetermined set position (notifying process at the set position) will be described. Next, a process for notifying a child carrying the child terminal 1 that a vehicle is approaching (notifying process based on vehicle detection) will be described. Next, a process (photography request process) when a request for photography is made from the parent terminal 2 to the child terminal 1 carried by a child will be described. Furthermore, a process (emergency process) when the child feels that there is an emergency situation and operates the operation button 19 will be explained. Note that the notification process at the set position, the notification process by vehicle detection, and the photographing request process are processes that are executed in a normal state in which no emergency signal is output from the operation button 19 of the child terminal 1. On the other hand, the emergency situation process is a process that is executed in an emergency state when an emergency signal is output from the operation button 19.

≪Notification processing at set position≫
The details of the process of notifying the person carrying the child terminal 1 will be explained. Here, the set position includes, for example, a point (for example, a safety confirmation point, etc.) where a predetermined action such as a stopping action, a right/left checking action, or a hand raising action is required to be performed. Specifically, the set position is a position on a route taken by a child carrying the child terminal 1, and is, for example, a position where there is a possibility that the child may be in danger. The set locations include, for example, intersections on the route, locations on sidewalks separated from roadways, and the vicinity of potentially dangerous structures.

The setting position is set, for example, by a parent carrying the parent terminal 2 operating the parent terminal 2 while walking along the school route with the child carrying the child terminal 1 on the way to and from school. When setting the setting position, the parent in possession of the parent terminal 2 should inform the child carrying the child terminal 1 that it is the setting position and instruct the child to perform predetermined actions such as stopping, checking left and right, and raising hands. It is preferable to do this while explaining that it is necessary to do so. Setting position information indicating the setting position set by the parent operating the parent terminal 2 is transmitted to the child terminal 1 via the server 3 and stored in the storage unit 33 of the server 3 and the memory 22 of the child terminal 1. .

The notification to the child carrying the child terminal 1 is controlled, for example, when the position determination unit 20a of the child terminal 1 determines that the distance between the current position of the child terminal 1 and the set position has become shorter than a predetermined distance. This is performed by the section 20 vibrating the vibrator 17. Note that the notification to the child carrying the child terminal 1 may be performed by the control unit 20 generating a voice or a buzzer sound from the speaker 16, or by causing the light 14 to emit light.

FIG. 5 is a diagram schematically showing the start timing of the notification process at the set position. As shown in FIG. 5, it is assumed that a child C1 who is carrying the child terminal 1 is walking along a route rt that goes straight toward an intersection and turns right at the intersection. Further, it is assumed that the set position PT1 is set in advance at the position of an intersection. Note that it is preferable that the set position PT1 is set on the route rt that the child C1 walks, rather than the center of the intersection. For example, on a road divided into a road and a sidewalk, the route rt is the sidewalk, and the set position PT1 is set on the sidewalk (more specifically, at the boundary between the sidewalk and the road).

In the child terminal 1, when the position determination unit 20a determines that the child C1 has approached a position that is a predetermined distance dt1 from the set position PT1 (that is, the predetermined range ARP shown in the figure), the control unit 20 controls the notification information. is output to cause the vibrator 17 to vibrate. The predetermined distance dt1 is, for example, a distance of about several meters. Further, the control unit 20 may change the intensity of notification (for example, the intensity of vibration) depending on the distance to the set position PT1. The child C1 is notified of the set position PT1 (that is, the intersection) by the vibrator 17, and walks while paying attention to the surroundings. Therefore, it is possible to suppress contact between the child C1 and the vehicle m traveling in the direction of movement of the child C1.

FIG. 6 is a flowchart illustrating an example of notification processing at a set position. The process of the flowchart shown in FIG. 6 is repeatedly executed at predetermined time intervals in the child terminal 1. First, the position acquisition unit 11 of the child terminal 1 acquires position information indicating the position of the child terminal 1 (the position of the child C1) (step S11: position detection step). Next, the position determining unit 20a of the child terminal 1 determines whether the distance from the position of the child C1 indicated by the acquired position information to the set position PT1 indicated by the set position information stored in the memory 22 is less than a predetermined distance dt1. It is determined whether there is one (step S12).

If the position determining unit 20a determines that the distance from the child C1's position to the set position PT1 is not less than the predetermined distance dt1, the process of the flowchart shown in FIG. 6 ends. On the other hand, if the position determining unit 20a determines that the distance from the position of the child C1 to the set position PT1 is less than the predetermined distance dt1, the position determining unit 20a outputs the child C1 notification information and causes the vibrator 17 to vibrate. (Step S13). In this way, the child C1 who is carrying the child terminal 1 is notified that the child terminal 1 is approaching the set position.

Further, when the vehicle is located within the range of the predetermined distance dt1, the vehicle detection unit 20b may transmit caution information to the vehicle m to notify the presence of the child C1. For example, when it is determined that the distance from child terminal 1 (i.e., child C1) to vehicle m has become less than a predetermined distance dt1, vehicle detection unit 20b generates caution information to notify vehicle m of the presence of the child. The communication unit 21 then outputs the signal to the vehicle m. For example, when the vehicle m receives the caution information from the child terminal 1, the vehicle m notifies the driver of the presence of the child using a display section and a speaker provided in the vehicle m. Based on the information provided from the vehicle m, the driver of the vehicle m can pay attention to the presence of the child C1 even if the child C1 cannot be visually recognized. Note that the timing at which the vehicle detection unit 20b generates the caution information and the timing at which the caution information is output toward the vehicle m are merely examples. For example, the vehicle detection unit 20b may generate caution information or output caution information when the vehicle m is located further away than a predetermined distance dt1.

Further, the vehicle detection unit 20b may turn on the light 14 when it is determined that the distance from the child terminal 1 (ie, child C1) to the vehicle m has become less than or equal to a predetermined distance dt1. By turning on the light 14, it is possible to make the driver of the vehicle m more aware of the presence of the child C1. Note that the timing of turning on the light 14 is an example. For example, the light 14 may be turned on when the vehicle m is located further away than a predetermined distance dt1.

In addition, although the example mentioned above demonstrated the case where the distance from the position of the child C1 to the setting position PT1 is a straight line distance, it is not limited to this. The distance from the position of the child C1 to the set position PT1 may be a distance along the route rt of the child C1. Furthermore, in the example described above, when notifying the child C1 that the child C1 is approaching the set position, the intensity of the notification (for example, the intensity of vibration) may be changed depending on the distance to the set position PT1. By performing such notification, it is possible to suppress the notification from being performed for a long time and to prevent the child C1 from getting used to the notification state.

≪Notification processing by vehicle detection≫
FIG. 7 is a flowchart illustrating an example of notification processing based on vehicle detection. The process of the flowchart shown in FIG. 7 is repeatedly executed in the child terminal 1 at predetermined time intervals. First, the vehicle detection unit 20b of the child terminal 1 determines whether a vehicle m approaching from behind the child C1 has been detected (step S21: object detection step). The vehicle detection unit 20b determines, based on the detection signal from the radar 12, whether a vehicle m approaching from behind the child C1 has been detected.

If the vehicle detection unit 20b determines that the vehicle m approaching from behind the child C1 has not been detected, the process of the flowchart shown in FIG. 7 ends. On the other hand, when the vehicle detection unit 20b determines that the vehicle m approaching from behind the child C1 has been detected, it outputs notification information and causes the vibrator 17 to vibrate (step S22). In this way, the child C1 who is carrying the child terminal 1 is notified that the vehicle m is approaching from behind.

Further, when a vehicle m approaching from behind the child C1 is detected, the vehicle detection unit 20b may transmit caution information to the vehicle m to notify the presence of the child C1. For example, when a vehicle m approaching from behind the child C1 is detected, the vehicle detection unit 20b generates caution information that informs the vehicle m of the presence of the child, and outputs it from the communication unit 21 to the vehicle m. Note that the timing at which the vehicle detection unit 20b generates the caution information and the timing at which the caution information is output toward the vehicle m are merely examples. For example, the vehicle detection unit 20b may generate caution information or output caution information when the vehicle m approaches closer than a preset distance.

Furthermore, the vehicle detection unit 20b may turn on the light 14 when the vehicle m approaching from behind the child C1 is detected. Note that the timing of turning on the light 14 is an example. For example, the light 14 may be turned on when the vehicle m approaches closer than a preset distance.

≪Photography request processing≫
FIG. 8 is a flowchart illustrating an example of the photographing request process of the first child terminal 1A. Here, the two child terminals 1 will be explained separately as the first child terminal 1A and the second child terminal 1B as described above. Further, the two parent terminals 2 will be explained separately as the first parent terminal 2A and the second parent terminal 2B as described above. When an instruction to request photographing by the first child terminal 1A is input to the first parent terminal 2A, the normal time information generating section 32a of the server 3 generates normal time child terminal photographing request information. Note that the normal time child terminal photographing request information generated by the normal time information generation unit 32a of the server 3 at this time is not generated as emergency response information, but is generated as normal state processing. The normal time child terminal photographing request information generated by the normal time information generation unit 32a of the server 3 is transmitted to the first child terminal 1A via the network N.

As shown in FIG. 8, in the photographing request process, first child terminal 1A receives information indicating a request for photographing (normal child terminal photographing request information) (step S31). The control unit 20 of the first child terminal 1A notifies the child C1 carrying the first child terminal 1A, for example, by voice (step S32). When the normal time child terminal photographing request information is input, the control unit 20 of the first child terminal 1A controls the speaker 16 to output a sound indicating that a photographing request has been made. At this time, the control unit 20 may also provide notification using the vibrator 17.

Subsequently, the control unit 20 of the first child terminal 1A determines whether or not photography is permitted (step S33). The control unit 20 of the first child terminal 1A determines that photographing is permitted when the operation button 19 is operated by the child C1. That is, the control unit 20 of the first child terminal 1A determines that photographing is permitted when an operation signal is output from the operation button 19. Note that the first child terminal 1A may constantly take pictures and record the picture information. In such a case, in step S33, the control unit 20 of the first child terminal 1A may determine whether or not output of the photographing information is permitted. When the first child terminal 1A is constantly photographing, in order to suppress the amount of photographic information to be stored, the It is also possible to select the photographing information to be stored.

If the control unit 20 of the first child terminal 1A determines that photographing is not permitted, it ends the process of the flowchart shown in FIG. On the other hand, if the control unit 20 of the first child terminal 1A determines that photography is permitted, it outputs photography information (step S34). The output photographing information is transmitted to the first parent terminal 2A via the network N, for example, the server 3. Note that, if the first child terminal 1A and the first parent terminal 2A can communicate without going through the server 3, the shooting information output from the first child terminal 1A is transmitted to the first child terminal 1A without going through the server 3. 1 may be transmitted to the parent terminal 2A. Moreover, the photographing information output from the first child terminal 1A is transmitted without going through the network N when the first child terminal 1A and the first parent terminal 2A can communicate without going through the network N. It may also be transmitted to the first parent terminal 2A.

Here, the photographing request processing in the first child terminal 1A and the first parent terminal 2A has been described. Such photographing request processing can be performed on the second child terminal 1B and the second parent terminal 2B in the same way as in the case of the first child terminal 1A and the first parent terminal 2A.

≪Emergency handling≫
9 to 12 are flowcharts showing an example of emergency situation processing. Here, the two child terminals 1 will be explained separately as the first child terminal 1A and the second child terminal 1B as described above. Further, the two parent terminals 2 will be explained separately as the first parent terminal 2A and the second parent terminal 2B as described above. FIG. 9 is a flowchart showing an example of emergency processing by the first child terminal 1A. FIG. 10 is a flowchart illustrating an example of emergency processing by the server 3. FIG. 11 is a flowchart showing an example of emergency processing by the first parent terminal 2A. FIG. 12 is a flowchart showing an example of emergency processing by the second child terminal 1B.

The emergency situation process is started when the operation button 19 of the child terminal 1 is operated without any notification accompanying the photographing request process. Here, the description will be made assuming that the operation button 19 of the first child terminal 1A is operated. As shown in FIG. 9, the control unit 20 of the first child terminal 1A determines whether the operation button 19 has been operated (step S41). The control unit 20 of the first child terminal 1A determines that the operation button 19 has been operated when an emergency signal is input from the operation button 19. Note that if the control unit 20 of the first child terminal 1A determines that the operation button 19 is not operated, it repeats step S41 at predetermined time intervals.

When the operation button 19 is operated, the control unit 20 of the first child terminal 1A starts recording (step S42). Recording here means storing photographic information obtained by photographing with the camera 18 in the memory 22. The control unit 20 of the first child terminal 1A performs photography by controlling the camera 18 using the photography control unit 20c based on the emergency child terminal photography request information output from the control unit 32 of the server 3. Note that if the first child terminal 1A is constantly recording, step S42 can be omitted.

The control unit 20 of the first child terminal 1A outputs an emergency signal when recording is started. The first child terminal 1A causes the emergency communication control unit 20e to transmit the emergency signal input from the operation button 19 to the communication unit 21 (step S43). Further, the control unit 20 of the first child terminal 1A stops normal processing (step S44). Here, the control unit 20 of the first child terminal 1A stops the operation of the radar 12 using the radar stop unit 20d based on the operation restriction information output from the control unit 32 of the server 3. By stopping the operation of the radar 12, the above-described vehicle detection process is stopped. For example, when the radar 12 is stopped, the vehicle detection process is stopped. In addition, the control unit 20 of the first child terminal 1A stops the above-mentioned setting position notification processing and the above-mentioned photographing request processing based on the operation restriction information output from the control unit 32 of the server 3. Good too. By stopping such normal processing, the notification in the normal state is stopped from being transmitted to the child C1 during the period of the emergency state, and it is possible to prevent the child C1 from receiving the notification and becoming confused.

Note that the processing order of step S42, step S43, and step S44 can be changed arbitrarily. In other words, the start of recording, the output of the emergency signal, and the stop of normal processing can be performed in a different order.

After stopping the normal processing, the control unit 20 of the first child terminal 1A enables the first child terminal 1A to communicate with the first parent terminal 2A (step S45). The control unit 20 of the first child terminal 1A creates a state in which the first child terminal 1A and the first parent terminal 2A can communicate in real time using the emergency communication control unit 20e. In this way, by enabling real-time communication between the first child terminal 1A and the first parent terminal 2A, the child C1 carrying the first child terminal 1A can accurately communicate his or her situation to the guardian. becomes possible.

Note that the control unit 20 of the first child terminal 1A may turn on the light 14 based on the lighting information output from the control unit 32 of the server 3. For example, the light 14 is turned on after it is determined in step S41 that the operation button 19 has been operated.

As shown in FIG. 10, the control unit 32 of the server 3 first determines whether an emergency signal has been received (step S51). The emergency signal output from the first child terminal 1A in step S43 described above is input to the control unit 32 of the server 3. When the emergency signal is input as described above, the control unit 32 of the server 3 determines that the emergency signal has been received. Note that if the control unit 32 of the server 3 determines that no emergency signal has been received, it repeats step S51 at predetermined time intervals.

Upon receiving the emergency signal, the control unit 32 of the server 3 generates emergency response information (step S52: emergency response information generation step). Here, the control unit 32 generates emergency response information using the emergency information generation unit 32b. In the present embodiment, the emergency information generation unit 32b generates the above-mentioned operation restriction information, other child terminal photographing request information, emergency situation notification information, other child terminal photographing transfer information, and emergency child terminal photographing request as emergency response information. Generates information, notification selection information, and lighting information.

The control unit 32 of the server 3 outputs emergency response information to the first child terminal 1A (step S53). Here, the control unit 32 of the server 3 transmits operation restriction information, emergency child terminal photography request information, and lighting information. Further, the control unit 32 of the server 3 calculates the distance between the first child terminal 1A and the second child terminal 1B (step S54). In this embodiment, an example in which there is one second child terminal 1B will be described, but if there are multiple second child terminals 1B (that is, other child terminals 1 for the first child terminal 1A), The distance between the first child terminal 1A and each second child terminal 1B is calculated. For example, the control unit 32 of the server 3 determines the first current position of the first child terminal 1A and the second current position of the second child terminal 1B. The distance to the second child terminal 1B is calculated. For example, the control unit 32 of the server 3 can constantly grasp the first current position and the second current position by periodically receiving current position information from the first child terminal 1A and the second child terminal 1B. There is.

The control unit 32 of the server 3 determines whether the distance between the first child terminal 1A and the second child terminal 1B is shorter than a predetermined distance (step S55). The control unit 32 of the server 3 compares, for example, the distance between the first child terminal 1A and the second child terminal 1B with a predetermined distance stored in the storage unit 33.

If the distance between the first child terminal 1A and the second child terminal 1B is not shorter than a predetermined distance, the control unit 32 of the server 3 performs step S57, which will be described later. On the other hand, if the distance between the first child terminal 1A and the second child terminal 1B is shorter than a predetermined distance, the control unit 32 of the server 3 transfers the emergency response information to the second child terminal 1B. (step S56). Here, the control unit 32 of the server 3 transmits other terminal photographing request information and other terminal photographing transfer information.

Subsequently, the control unit 32 of the server 3 outputs emergency response information and photographing information to the first parent terminal 2A (step S57). Here, the control unit 32 of the server 3 transmits emergency notification information and report selection information as emergency response information. Further, the control unit 32 of the server 3 transmits the photographing information transmitted from the first child terminal 1A and the photographing information transmitted from the second child terminal 1B to the first parent terminal 2A. By receiving these photographic information, the first parent terminal 2A can confirm the emergency situation using a moving image or a still image.

Subsequently, the control unit 32 of the server 3 outputs emergency response information to the second parent terminal 2B (step S58). For example, the control unit 32 of the server 3 transmits emergency notification information and report selection information to the second parent terminal 2B as emergency response information. The second parent terminal 2B, which has received the emergency situation notification information and report selection information in this way, displays on the display unit 42 that an emergency situation has occurred at the first child terminal 1A, and whether or not to report it to the police agency.
