<First Embodiment>
An overview of the control device of the present disclosure will be described.

FIG. 1 is a diagram schematically showing an example of the configuration of a notification control system 1000 including the control device 100. FIG. As shown in FIG. 1 , notification control system 1000 includes control device 100 and communication device 200 . The control device 100 is communicably connected to the communication device 200 .

The communication device 200 is a portable terminal such as a smart phone, tablet, and mobile phone, but is not limited to this example. The communication device 200 may be, for example, a laptop personal computer. Communication device 200 is a device capable of acquiring its own location information.

FIG. 2 is a block diagram showing an example of the functional configuration of the control device 100 of the first embodiment. As shown in FIG. 2 , the control device 100 includes an acquisition unit 110 , a generation unit 120 and a notification unit 130 .

The acquisition unit 110 acquires various types of information from the communication device 200 . For example, the acquisition unit 110 acquires position information indicating the position of the communication device 200 from the communication device 200 when a disaster occurs. Acquisition unit 110 also acquires attribute information about a person who possesses communication device 200 from communication device 200 . Attribute information is information indicating attributes of a person. The attributes are, for example, a person's age, presence/absence of disability, presence/absence of pregnancy, and presence/absence of disease, but are not limited to these examples. Note that the timing of acquiring the position information and the attribute information may be different. In this way, the acquisition unit 110 acquires the position information of the communication device 200 and the attribute information indicating the attributes of the person who possesses the communication device 200 when a disaster occurs. Acquisition unit 110 is an example of acquisition means.

The generation unit 120 generates notification information based on the acquired position information and attribute information. The notification information is information including information about disasters. For example, the generation unit 120 assumes that the location of the communication device 200, that is, the location of the person who owns the communication device 200, is within a disaster-related area. A disaster-related area indicates a place where a disaster has occurred or a place where a disaster is likely to occur. At this time, the generating unit 120 generates, as notification information, information about the disaster that has occurred, information indicating evacuation instructions, and the like. For example, if an earthquake occurs and a person is located near the coast, there is a possibility that a tsunami will occur. good.

Here, the generation unit 120 further uses the attribute information of the person. For example, assume that an earthquake has occurred and a person carrying communication device 200 is near the coast. If the person is 80 years old, it is likely that they will have difficulty moving quickly. Therefore, the generation unit 120 generates notification information including, for example, an evacuation instruction to a location on the second floor or higher of a nearby building. Also, for example, when a person is 20 years old and does not suffer from any disability or disease, there is a high possibility that the person can move quickly. Therefore, the generation unit 120 generates notification information including an evacuation instruction to a place that is presumed to be safer, such as a mountain or a shelter, for example. In this way, the generation unit 120 generates notification information including disaster information according to the position information and the attribute information. The generation unit 120 is an example of generation means.

The notification unit 130 notifies the communication device 200. Specifically, the notification unit 130 notifies the communication device 200 of the disaster by transmitting the generated notification information to the communication device 200 . For example, when the communication device 200 receives notification information, the communication device 200 outputs the notification information. Notification unit 130 is an example of notification means.

Next, an example of the operation of the control device 100 will be explained using FIG. In addition, in the present disclosure, each step in a flowchart or a sequence diagram is expressed using a number attached to each step, such as “S1”.

FIG. 3 is a flowchart explaining an example of the operation of the control device 100. FIG. When a disaster occurs, the acquisition unit 110 acquires position information of a communication device and attribute information indicating attributes of a person who owns the communication device (S1). The generating unit 120 generates notification information including information about disasters according to the position information and the attribute information (S2). Then, the notification unit 130 transmits the generated notification information to the communication device and notifies the communication device of the disaster (S3).

In this way, when a disaster occurs, the control device 100 of the first embodiment acquires the position information of the communication device and the attribute information indicating the attributes of the person possessing the communication device, The notification information including the information about the disaster is generated according to the attribute information. Then, the control device 100 transmits the generated notification information to the communication device and notifies the communication device of the disaster. Thereby, for example, the control device 100 can notify each person of the content suitable for each person in the event of a disaster. That is, the control device 100 can notify the information about the disaster according to the person.

<Second embodiment>
Next, a notification control system according to the second embodiment will be described. In the second embodiment, the control device 100 explained in the first embodiment will be explained in more detail.

FIG. 4 is a block diagram showing an example of the functional configuration of the notification control system 1000 of the second embodiment. The notification control system 1000 includes a control device 100 and a communication device 200 as shown in FIG. A plurality of communication devices 200 may exist. In this case, the control device 100 can communicate with each of the multiple communication devices 200 . Further, communication may be possible between the communication devices 200 .

The network built in the notification control system 1000 does not have to be limited to a specific method. For example, the network constructed in the notification control system 1000 may be a wireless LAN (Local Area Network), a public line network, a mobile data communication network, or a combination of these networks. As mobile data communication networks, there are 3rd generation mobile communication systems (3G: 3rd Generation), LTE (Long Term Evolution), 4th generation mobile communication systems (4G: 4th Generation), 5th generation mobile communication systems (5G: 5th Generation), etc.

[Details of communication device 200]
Communication device 200 includes communication unit 210 , input reception unit 220 , position information acquisition unit 230 , and output unit 240 .

The communication unit 210 performs various communications with the control device 100 . Specifically, the communication unit 210 transmits position information and attribute information to the control device. The communication unit 210 also receives notification information from the control device 100 .

The input reception unit 220 receives various inputs from the person who owns the communication device 200 . Specifically, the input reception unit 220 receives an attribute input from a person. For example, the input reception unit 220 receives an input of age, presence/absence of disability, presence/absence of pregnancy, and presence/absence of disease from a person as attributes. The input reception unit 220 then transmits attribute information indicating the input attribute to the control device 100 via the communication unit 210 . At this time, the attribute information includes identification information that identifies the communication device 200 . The input receiving unit 220 is an example of input receiving means.

The location information acquisition unit 230 acquires location information of the communication device 200 . For example, the position information acquisition unit 230 receives a signal transmitted from a positioning satellite of a GNSS (Global Navigation Satellite System) such as a GPS (Global Positioning System) satellite, and based on the received signal, the position information acquisition unit 230 indicates the position of its own device. It may be configured to obtain information. For example, when receiving a position information acquisition request, which will be described later, the position information acquisition unit 230 may acquire position information and transmit the acquired position information to the control device 100 . At this time, the positional information acquisition unit 230 transmits the acquired positional information together with the identification information to the control device 100 via the communication unit 210 . The position information acquisition unit 230 is an example of position information acquisition means.

The output unit 240 outputs various information. For example, the output unit 240 outputs notification information, which will be described later. At this time, the output unit 240 may output the notification information by displaying it on the display provided in the communication device 200, or may output the notification information by outputting sound from the speaker provided in the communication device 200. You may The output unit 240 is an example of output means.

[Details of control device 100]
The control device 100 includes an acquisition unit 110 , a generation unit 120 and a notification unit 130 . Also, as shown in FIG. 4, the control device 100 has a communication device database 190 . Note that the communication device database 190 may be provided in an external device that can communicate with the control device 100 . Henceforth, a database is also called DB.

The acquisition unit 110 includes an information acquisition unit 111 and an area identification unit 112 . The information acquisition unit 111 acquires attribute information from the communication device 200 in advance, for example. Then, the acquired attribute information is registered in the communication device DB 190 . FIG. 5 is a diagram showing an example of attribute information included in the communication device DB 190. As shown in FIG. As shown in FIG. 5, the attribute information associates identification information and attributes of the communication device 200 . For example, the record in the first row indicates that a person who owns a communication device with identification information "001" is "85" years old and has "impairment of lower limbs."

In addition, the information acquisition unit 111 acquires position information from the communication device 200 at a predetermined timing such as when a disaster occurs. At this time, the information acquisition unit 111 acquires the location information from, for example, the communication device 200 that has received the request to acquire the location information. A request for position information acquisition is made by the area identification unit 112 .

The region specifying unit 112 specifies the region for which the location information acquisition request is made. Then, the region specifying unit 112 makes a request to the communication device 200 in the specified region. Here, the area identification unit 112 may identify the area for which the request is made, for example, based on disaster information distributed by government offices. The disaster information distributed by public offices includes, for example, weather bulletins, warnings, warnings, emergency warnings, and the like, such as earthquakes, tsunamis, typhoons, floods, and eruptions. Also, the disaster information may be large-scale terrorism information or the like. Such disaster information includes information indicating areas associated with disasters, such as areas where disasters have occurred and areas where disasters may occur. The area identification unit 112 may identify an area related to the disaster as the area for making the request. Further, the area identification unit 112 may request the communication devices 200 in the identified area to acquire the location information by broadcasting to the identified area. In this way, when a disaster occurs, the area identification unit 112 identifies an area related to the disaster, and transmits a position information request to the communication devices 200 in the identified area.

The information acquisition unit 111 acquires the identification information of the communication device 200 together with the position information. Then, the information acquisition unit 111 acquires attribute information including the acquired identification information from the communication device DB 190 . For example, assume that the information shown in FIG. 5 is registered in the communication device DB 190 . When the information acquisition unit 111 acquires “001” as the identification information, it acquires the attribute information of the first row record including the acquired identification information. Note that the information acquisition unit 111 may associate the acquired position information with the identification information and associate it with the communication device DB 190 .

The generation unit 120 generates notification information based on the location information and attribute information of the communication device 200 . The notification information is information about a disaster to be notified to the communication device 200 . An example of a method for generating notification information will now be described. Note that generation of notification information when an earthquake occurs and a tsunami warning is issued will be described below, but the scene in which notification information is generated is not limited to this example.

The generation unit 120 first identifies in which area the person who possesses the communication device 200 is located based on the position information. FIG. 6 is a diagram showing an example of areas. In the example of FIG. 6, area A, area B, and area C are set. Here, the area may be set in advance based on the degree of damage assumed in the hazard map corresponding to each disaster, for example. For example, the area may be set according to the flood depth assumed in the tsunami hazard map. Areas may also be set based on disaster information distributed by government offices. For example, when a tsunami warning and a tsunami advisory are issued, an area may be set for each region targeted by the tsunami warning and the tsunami advisory.

In the example of FIG. 6, it is predicted that an earthquake will occur at point X and a tsunami will occur from the sea toward areas B and C. Area B has Mt. X as a high ground, and Area C has Mt. Y as a high ground. Here, it is assumed that person H who possesses communication device 200 is located in area C. FIG. In this case, the generator 120 identifies that the person H is located in the area C from the position information of the communication device 200 . Then, the generation unit 120 generates notification information based on the position information and the attribute information of the person H. FIG. For example, assume that person H is 20 years old and has no disability or disease. In this case, it is assumed that the person H can move quickly. Therefore, the generation unit 120 generates notification information including, for example, a sentence "Please evacuate to Mt. Y." Also, for example, assume that person H is 85 years old and suffers from a lower extremity dysfunction. In this case, it is assumed that the person H cannot move quickly. Therefore, the generation unit 120 generates notification information including, for example, a sentence "Ask people around you for help" or a sentence "Please move to the top floor of the nearest building." If the person H is pregnant or sick, it is assumed that they cannot move quickly, so the generation unit 120 may generate similar notification information.

Note that notification information is not limited to this example. For example, assume that the notification information is information displayed on the communication device 200 . In this case, the generation unit 120 may generate the notification information by changing the display method of part of the text generated in advance according to the attribute. For example, it is assumed that a sentence "A tsunami warning has been issued. Please evacuate to Mt. Y immediately. If you have difficulty moving, please ask for help from those around you." If the person H is 85 years old and suffers from a functional disorder in the lower limbs, the generation unit 120 generates notification information such that the part "If you have difficulty moving, please seek help from those around you" is highlighted. may be generated. Examples of highlighting include enlarging characters and changing colors. Similarly, when the notification information is information output by voice in the communication device 200, the generation unit 120 may change the volume of part of the text generated in advance according to the attribute.

Also, the generation unit 120 does not have to generate notification information for all communication devices 200 using both position information and attribute information. The generation unit 120 may generate notification information depending on whether the position information satisfies a predetermined condition. For example, in the example of FIG. 6, area A indicates a place farther from the sea than areas B and C. In FIG. Therefore, area A is assumed to suffer less damage from tsunami than area B and area C. Therefore, the generation unit 120 may uniformly generate notification information including a sentence "Keep away from the coast" for the communication devices 200 whose location information is in area A. In other words, when the location information is within area A where the damage is assumed to be small, the generating unit 120 does not need to generate notification information according to the attribute. The generation unit 120 does not have to generate the notification information according to the attribute, not limited to this example, when the location information is away from the point where the disaster occurred by a predetermined distance or more.

In this way, the generating unit 120 generates notification information according to the position information when the position information satisfies the predetermined condition, and generates notification information according to the position information and the attribute information when the position information does not satisfy the predetermined condition. Notification information may be generated. As a result, the control device 100 does not necessarily have to generate notification information corresponding to the position information and the attribute information for all the communication devices 200, so that the processing load can be reduced.

The notification unit 130 transmits the notification information generated by the generation unit 120 to the communication device 200 .

[Example of operation of notification control system 1000]
Next, an example of the operation of the notification control system 1000 of the second embodiment will be explained using FIG. FIG. 7 is a sequence diagram illustrating an example of the operation of the notification control system 1000. As shown in FIG. More specifically, FIG. 7 is an operation example when the control device 100 acquires attribute information.

The input reception unit 220 of the communication device 200 receives an attribute input from the person who owns the communication device 200 (S101). Then, the communication unit 210 transmits the attribute information indicating the input attribute and the identification information of the communication device 200 to the control device 100 (S102). The information acquisition unit 111 of the control device 100 associates the received attribute information with the identification information and registers them in the communication device DB 190 (S102).

Next, another example of the operation of the notification control system 1000 will be described using FIG. FIG. 8 is a sequence diagram illustrating another example of the operation of notification control system 1000. In FIG. More specifically, FIG. 8 is an operation example when the control device 100 generates notification information.

The area identification unit 112 of the control device 100 identifies an area to which a request for acquiring location information will be sent when a disaster occurs (S201). Then, the region specifying unit 112 transmits a request for position information to the communication device 200 in the specified region (S202).

Upon receiving the request via the communication unit 210, the location information acquisition unit 230 of the communication device 200 acquires location information (S203). The location information acquisition unit 230 transmits the location information and the identification information via the communication unit 210 (S204).

After acquiring the position information and the identification information from the communication device 200, the information acquisition unit 111 of the control device 100 acquires the attribute information from the communication device DB 190 based on the identification information (S205). The generation unit 120 generates notification information based on the position information and the attribute information (S206). And the notification unit 130: The notification information is transmitted to the communication device 200 (S207).

When the output unit 240 of the communication device 200 acquires the notification information via the communication unit 210, it outputs the notification information (S208).

In this way, when a disaster occurs, the control device 100 of the second embodiment acquires the position information of the communication device and the attribute information indicating the attributes of the person possessing the communication device, The notification information including the information about the disaster is generated according to the attribute information. Then, the control device 100 transmits the generated notification information to the communication device and notifies the communication device of the disaster. Thereby, for example, the control device 100 can notify each person of the content suitable for each person in the event of a disaster. That is, the control device 100 can notify the information about the disaster according to the person.

Further, when a disaster occurs, the control device 100 of the second embodiment may specify an area related to the disaster and transmit a position information request to communication devices in the specified area. . As a result, the control device 100 does not have to generate notification information for all the communication devices 200, so the processing load can be reduced.

Further, the control device 100 of the second embodiment generates notification information according to the position information when the position information satisfies the predetermined condition, and when the position information does not satisfy the predetermined condition, the position information and the attribute information. Notification information may be generated according to the Accordingly, the control device 100 does not need to generate notification information using attribute information for all communication devices that have acquired position information. Therefore, the control device 100 can reduce the processing load.

[Modification 1]
In the embodiment described above, an example in which the communication device 200 transmits the attribute information to the control device 100 in advance has been described. The timing of transmitting the attribute information is not limited to this example. For example, the input reception unit 220 of the communication device 200 may store the attribute information in a storage device (not shown) included in the communication device 200 upon receiving the attribute input. When the communication device 200 receives a request for position information from the control device 100 , the communication device 200 may transmit the position information, the attribute information, and the identification information to the control device 100 .

<Third Embodiment>
Next, a notification control system according to the third embodiment will be described. In the third embodiment, an example of tracking communication devices will be described. It should be noted that description of some of the content that overlaps with the content described in the first and second embodiments will be omitted.

FIG. 9 is a block diagram showing an example of the configuration of the notification control system 1001 of the third embodiment. As shown in FIG. 9 , notification control system 1001 includes control device 101 and communication device 201 . The control device 101 and the communication device 201 have the functions described below in addition to the functions of the control device 100 and the communication device 200, respectively.

[Details of communication device 201]
The communication device 201 includes a communication section 210 , an input reception section 221 , a position information acquisition section 231 , an output section 240 and a speed determination section 250 .

The input reception unit 221 receives an input of the person's situation from the person who owns the communication device 201 . The status of a person includes an injury sustained by the person, whether or not the person can move, and the like. For example, the input receiving unit 221 may receive an input such as a sentence "I fell and injured my leg" or a sentence "I can't move because the road is blocked by a landslide".

The location information acquisition unit 231 acquires location information as needed. For example, the position information acquisition unit 231 periodically acquires the position information of its own device after the position information is requested from the control device 101 . Then, the position information acquisition unit 231 transmits the position information to the control device 101 via the communication unit 210 at any time. Here, the position information acquisition section 231 may change the frequency of acquiring position information based on the result determined by the speed determination section 250 .

The speed determination unit 250 acquires the moving speed of the communication device 201 . For example, the speed determination unit 250 acquires the moving speed using an acceleration sensor mounted on the communication device 201 . Then, the speed determination unit 250 determines whether or not the moving speed is less than the reference speed. The position information acquisition unit 231 reduces the frequency of acquiring position information when the moving speed is less than the reference value. Speed determination unit 250 is an example of speed determination means.

When the movement speed is slow, the amount of movement of the person carrying the communication device 201 is small. Then, even if the frequency of acquiring position information is high, the change in position information is small. Therefore, when the speed determination unit 250 determines that the moving speed is less than the reference speed, the position information acquiring unit 231 determines that the moving speed is slow, and reduces the frequency of acquiring position information. By reducing the frequency of acquiring position information in this way, the battery consumption of the communication device 201 can be reduced. Note that the speed determination unit 250 may determine whether or not the moving speed is equal to or higher than the second reference speed. At this time, the value of the second reference speed is greater than the value of the reference speed. Then, when it is determined that the moving speed is equal to or higher than the second reference speed, the position information obtaining unit 231 may increase the frequency of obtaining the position information.

[Details of the control device 101]
The control device 101 includes an acquisition unit 113 , a generation unit 121 and a notification unit 131 .

The acquisition unit 113 includes an information acquisition unit 114 and an area identification unit 112 . The information acquisition unit 114 acquires position information at any time. In addition, the information acquisition unit 114 also acquires information indicating the person's situation from the communication device 201 .

The generation unit 121 may generate notification information according to information indicating the person's situation. Specifically, when the information indicating the situation of the person is obtained by the information obtaining unit 114, the generation unit 121 generates notification information including the information indicating the situation of the person and the position information. At this time, the notification information may further include the person's attribute information. Then, the notification unit 131 transmits the notification information to another communication device different from the communication device that transmitted the information indicating the situation of the person. At this time, the notification unit 131 transmits the notification information to other communication devices within a predetermined distance from the position indicated by the position information based on the position information of the communication device that transmitted the information indicating the person's situation. As a result, for example, when there is an injured person who cannot move, it is possible to notify the people around the person that there is a person who cannot move.

Also, the generation unit 121 may generate notification information according to the moving direction of the communication device 201 . Specifically, when the information acquisition unit 114 acquires position information as needed, the generation unit 121 estimates the moving direction of the information acquisition unit 114 from changes in the position information. Then, the generation unit 121 generates notification information based on the estimated moving direction. For example, in the situation of FIG. 6, it is assumed that person H has been notified to move to Y mountain. In this case, when the person H is moving in the direction of Mt. Y, the generating unit 121 generates notification information including a document saying, for example, "Go straight to Mt. Y." Further, for example, when the person H is moving in the direction of the sea, the generating unit 121 generates notification information including a sentence, for example, "Please run away in the opposite direction."

[Operation example 1 of notification control system 1001]
Next, an example of operation of the notification control system 1001 of the third embodiment will be described using FIG. FIG. 10 is a sequence diagram explaining an example of the operation of the notification control system 1001. As shown in FIG. More specifically, FIG. 10 is an operation example when the control device 101 acquires information indicating the situation of a person.

The input reception unit 221 of the communication device 201 receives an input of the person's situation from the person who owns the communication device 201 (S301). The position information acquisition unit 231 acquires position information (S302). Then, the communication unit 210 transmits the information indicating the situation of the person, the position information, and the identification information (S303).

After acquiring the information indicating the situation of the person, the position information, and the identification information, the information acquisition unit 114 of the control device 101 acquires attribute information from the communication device DB 190 based on the identification information (S304). Then, the generation unit 121 generates notification information including information indicating the person's situation, attribute information, and position information (S305). The notification unit 131 transmits notification information to the communication device 201 that transmitted the information indicating the situation of the person and other communication devices within a predetermined distance.

[Operation example 2 of notification control system 1001]
Next, another example of the operation of the notification control system 1001 of the third embodiment will be explained using FIG. FIG. 11 is a sequence diagram explaining an example of the operation of the notification control system 1001. As shown in FIG. More specifically, FIG. 11 shows an operation example in which position information is acquired again after the control device 101 transmits notification information to the communication device 201 .

The location information acquisition unit 231 of the communication device 201 acquires location information (S401). The position information acquisition unit 231 transmits the position information and the identification information to the control device 101 (S402).

When the information acquisition unit 114 of the control device 101 acquires the position information and the identification information, the generation unit 121 estimates the movement direction based on changes in the position information (S403). At this time, for example, the generation unit 121 reads the position information registered in the communication device DB 190 based on the identification information, and estimates the moving direction based on the difference between the read position information and the acquired position information. good too. Then, the generation unit 121 generates notification information based on the movement direction (S404). The notification unit 131 transmits notification information to the communication device 201 (S405).

The output unit 240 of the communication device 201 outputs the notification information (S406). The speed determination unit 250 acquires the moving speed of its own device (S407). The speed determination unit 250 determines the moving speed (S408). For example, the speed determination unit 250 determines whether or not the moving speed is less than the reference speed. Then, when the moving speed is less than the reference speed, the position information acquisition unit 231 reduces the frequency of acquiring position information. After that, when the position information acquisition unit 231 acquires the position information, the notification control system 1001 may perform the operation of FIG. 11 again. Note that the processing of S407 to S409 may be performed at any timing.

In this way, the control device 101 of the third embodiment acquires position information from the communication device at any time, estimates the moving direction of the communication device from changes in the position information, and based on the estimated moving direction, Notification information may be generated. As a result, the control device 101 can monitor the person carrying the communication device 201 at any time. In addition, since the control device 101 can make a notification according to the moving direction of the person who has the communication device 201, for example, a person who is moving to a dangerous place can receive a notification including an instruction to move in a different direction. It can be carried out. That is, the control device 101 can perform notification suitable for the person.

Further, the control device 101 of the third embodiment acquires information indicating the situation of the person from the communication device, generates notification information including the information indicating the situation of the person, and determines the position indicated by the position information of the communication device. Notification information including information indicating the situation of the person may be transmitted to other communication devices within a predetermined distance. Thereby, for example, when there is a person who cannot move, the control device 101 can notify other persons around the person that there is a person who cannot move.

[Modification 2]
In the above-described embodiment, when the communication device 201 receives an input of a person's situation, the control device 101 notifies another communication device of the person's situation. When the communication device 201 receives an input of the person's situation, the communication device 201 may notify another communication device of the person's situation.

For example, when the input reception unit 221 of the communication device 201 receives an input of a person's situation, the communication unit 210 identifies other communication devices in the vicinity with which communication is possible. Then, the communication unit 210 transmits the information indicating the situation of the person and the position information to other communication devices.

[Modification 3]
In the above-described embodiment, an example has been described in which, when the communication device 201 receives an input of the person's situation from the person, the notification is made according to the person's situation. On the other hand, even if the communication device 201 has not received an input of the person's situation, the control device 101 may make a notification according to the person's situation.

For example, the information acquisition unit 114 of the control device 101 acquires position information and movement speed information of the communication device 201 . At this time, the generating unit 121 may determine whether the person holding the communication device 201 has not moved for a certain period of time or longer, based on the positional information or the moving speed information. For example, if the location information of the communication device 201 has not changed for 30 minutes, the generation unit 121 determines that the person holding the communication device 201 has not moved for 30 minutes. As described above, when the generation unit 121 determines that the person has not moved for a certain period of time or longer, the generation unit 121 generates information indicating that the person cannot move as information indicating the situation of the person. do. Then, the generation unit 121 generates notification information including, for example, the generated information indicating the situation of the person and the position information.

In this way, the control device 101 of Modification 3 determines the situation of the person according to the information acquired from the communication device 201 even when the communication device 201 does not accept the input of the situation of the person. good. Accordingly, the control device 101 can make a notification according to the situation of the person even when the person using the communication device 201 cannot operate the communication device 201 by himself or herself.

<Fourth Embodiment>
Next, a notification control system according to the fourth embodiment will be described. In the fourth embodiment, an example in which a control device transmits notification information to a communication device and a loudspeaker device will be described. Further, in this embodiment, the notification information is audio information, and the notification information is output as audio in each of the communication device and the loudspeaker device. Some descriptions of the contents that overlap with the contents described in the first, second, and third embodiments will be omitted.

FIG. 12 is a diagram schematically showing an example of the configuration of the notification control system 1002. As shown in FIG. As shown in FIG. 12, notification control system 1002 includes control device 102 and communication device 201 . Notification control system 1002 is communicably connected to loudspeaker 300 . The public address device 300 has a function of outputting sound. The loudspeaker device 300 may be, for example, an outdoor-installed speaker that is used in a municipal disaster prevention radio system. A plurality of loudspeaker devices 300 may be installed.

[Details of the control device 102]
FIG. 13 is a block diagram showing an example of the functional configuration of the notification control system 1002 of the fourth embodiment. The control device 102 includes an acquisition unit 113 , a generation unit 122 and a notification unit 132 . Furthermore, the control device 102 includes a communication device DB 190 and a loudspeaker device DB 191 .

In the public address system DB 191, information identifying the public address system 300 and position information indicating the position where the public address system 300 is installed are registered in association with each other. Further, in the loudspeaker DB 191 , the listening range, which is the range in which the sound output from the loudspeaker 300 can be heard, is associated with information identifying the loudspeaker 300 .

The generation unit 122 generates first notification information and second notification information, which are audio information, as notification information. The first notification information is notification information transmitted to the communication device 201 , and the second notification information is notification information transmitted to the loudspeaker device 300 . Here, the generation unit 122 may generate the second notification information according to the position information of the loudspeaker device 300 . For example, in the example of FIG. 6, assume that a loudspeaker device 300 is installed in each area. The generating unit 122 acquires the position information of the loudspeaker device 300 from the loudspeaker DB 191, and sends the second notification including the sentence "Please evacuate to Mt. Y" to the loudspeaker device 300 installed in the area C. Generate information. Here, in the public address system 300, it is desirable to output the sound with a gap in order to prevent the sound from echoing or interfering with the sound of another public address system. Therefore, the generation unit 122 generates the second notification information so as to include a gap in the middle of the sentence. For example, the generation unit 122 may generate, as the second notification information, a sound in which a pause is added for each clause of the sentence.

Also, in the example of FIG. 6, assume that there is a person who has the communication device 201 in area C. At this time, the generation unit 122 generates the first notification information including, for example, the sentence "Please evacuate to Mt. Y." Unlike the loudspeaker device 300, the communication device 201 does not require a gap when outputting the sound. Therefore, the generation unit 122 may generate the first notification information so that the middle of the sentence is less than the voice of the second notification information. Note that the generation unit 122 may generate the first notification information according to the position information and the attribute information when generating the first notification information.

The notification unit 132 transmits the first notification information to the communication device 201. Also, the notification unit 132 transmits the second notification information to the loudspeaker device 300 . As a result, the communication device 201 outputs the disaster-related information included in the first notification information. Also, the loudspeaker 300 outputs the disaster-related information included in the first notification information.

Also, the notification unit 132 may change the notification method according to the position of the communication device 201 . For example, assume that the position indicated by the position information of the communication device 201 is outside the listening range of the loudspeaker device 300 and within a disaster-related area. At this time, the notification unit 132 may notify the first notification information multiple times. A person outside the listening range may not notice the sound from the public address system 300 . Therefore, by notifying the communication device 201 a plurality of times, it is possible to increase the possibility that the person will notice the notification.

[Example of operation of notification control system 1002]
Next, an example of the operation of the notification control system 1002 of the fourth embodiment will be explained using FIG. FIG. 14 is a sequence diagram illustrating an example of the operation of the notification control system 1002. As shown in FIG. More specifically, FIG. 14 shows an operation example when the control device 102 transmits notification information to the loudspeaker device 300 and the communication device 201 .

The processing from S501 to S505 is the same as the processing from S201 to S205 in FIG. 8, so the description is omitted. The generating unit 122 generates second notification information (S506). The generation unit 122 also generates the first notification information based on the position information and the attribute information (S507). Then, the notification unit 132 transmits the second notification information to the loudspeaker device 300 (S508). Also, the notification unit 132 transmits the first notification information to the communication device 201 (S509). The communication device 201 outputs first notification information (S510).

Note that this operation example is just an example, and the order of each process may be different. For example, the processing of S506 may be performed at any timing before S508. Conversely, the process of S508 may be performed at any timing after the process of S506.

As described above, when there is a public address device that outputs sound, the control device 102 of the fourth embodiment generates first notification information and second notification information, which are audio information, as notification information. The notification information may be sent to the communication device and the second notification information may be sent to the public address device. At this time, the first notification information is information including a sentence indicating information about the disaster, and the second notification information is information including a pause in the middle of the sentence. Thereby, the control device 102 of the fourth embodiment can notify both the communication device 201 and the loudspeaker device 300 of the information including the disaster information. In addition, since the loudspeaker 300 outputs a voice including pauses in the middle of a sentence, it is possible to prevent the echo of the voice and interference with the voice of another loudspeaker. Furthermore, since the communication device 201 outputs voice with fewer pauses in the middle of the sentence than the second notification information, the voice output time is shortened, and the person can be encouraged to act quickly.

Further, the control device 102 of the fourth embodiment, when the position indicated by the position information of the communication device is outside the listening range of the sound output by the loudspeaker and within the area related to the disaster, the communication The first notification information may be sent multiple times to the device. As a result, the control device 102 can increase the possibility that a person who may not notice the sound from the loudspeaker device 300 will notice the notification.
