Embodiments of the present disclosure are described below with reference to the drawings.

First Embodiment
An overview of the evacuation assistance device according to the first embodiment will be described.

The evacuation support device of the first embodiment acquires information from a management device installed at an evacuation shelter via an artificial satellite. The evacuation support device then performs various processes based on the acquired information. Here, we will explain the mechanism by which the evacuation support device acquires information from the management device in this application.

Figure 1 is a diagram showing a schematic example of a mechanism for acquiring information via an artificial satellite. In the example of Figure 1, a management device 200 is installed at an evacuation shelter. The management device 200 is a device including a computer such as a server. Furthermore, an evacuation support device 100 is installed at a local government facility. The evacuation support device 100 is a device including a computer such as a server. The local government facility is a facility managed by a local government. For example, the local government facility may be a government office, or an administrative agency related to meteorology, firefighting, police, and defense. Note that the location where the evacuation support device 100 is installed is not limited to this. In other words, the evacuation support device 100 may be installed at a facility managed by an organization or person other than the local government.

The management device 200 transmits, for example, information indicating the status of the evacuation shelter to the artificial satellite. The status of the evacuation shelter includes, for example, the location of the evacuation shelter, the opening status of the evacuation shelter, supplies at the evacuation shelter, and information on evacuees. The artificial satellite is, for example, a geostationary satellite. In particular, the artificial satellite may be a quasi-zenith satellite that passes above a specific region.

The evacuation support device 100 acquires information indicating the status of the evacuation shelter from an artificial satellite. At this time, the evacuation support device 100 may acquire the information from the artificial satellite via a control station. In this way, the evacuation support device 100 acquires information transmitted from the management device 200 installed in the evacuation shelter via the artificial satellite.

Next, an example of the functional configuration of the evacuation support device 100 will be described. FIG. 2 is a block diagram showing an example of the functional configuration of the evacuation support device 100. As shown in FIG. 2, the evacuation support device 100 includes an acquisition unit 110, an estimation unit 120, and an output control unit 130.

The acquisition unit 110 acquires information transmitted from the management device 200 via an artificial satellite. The management device 200 transmits existing goods information and evacuee information. Existing goods refer to goods present at an evacuation shelter. Goods are items used by evacuees at an evacuation shelter, such as food, clothing, bedding, and medical supplies. Goods present at an evacuation shelter are, for example, goods stockpiled at an evacuation shelter in the event of a disaster. The existing goods information may indicate the quantity of each type of goods. For example, the existing goods information may indicate the quantity of each type of food, such as hardtack, instant noodles, and water.

Evacuee information is information about evacuees who are in evacuation shelters. Evacuee information includes personal information about each evacuee, such as their age and gender.

The management device 200 is operated, for example, by a local government employee at an evacuation shelter. This operation causes the management device 200 to transmit existing goods information and evacuee information.

In this way, the acquisition unit 110 acquires existing supplies information indicating supplies present at the evacuation shelter and evacuee information indicating information about evacuees at the evacuation shelter from the management device 200 installed at the evacuation shelter via an artificial satellite. The acquisition unit 110 is an example of an acquisition means.

The estimation unit 120 estimates the shortage or surplus of supplies based on the acquired existing supply information and evacuee information. More specifically, the estimation unit 120 estimates the shortage or surplus of supplies required at the evacuation shelter. For example, it is assumed that information correlating the number of evacuees with consumption information indicating the number of supplies expected to be consumed in a specified period (estimated consumption number) is determined in advance. In this case, the estimation unit 120 acquires information indicating the number of evacuees from the evacuee information. The estimation unit 120 also identifies the consumption information corresponding to the acquired number of evacuees. The estimation unit 120 may then estimate the shortage or surplus of supplies based on the number of supplies indicated in the identified consumption information and the number of supplies indicated in the existing supply information.

At this time, the estimation unit 120 may estimate the shortage or surplus of supplies using machine learning. For example, the estimation unit 120 identifies consumption information at the evacuation shelter using a learning model that has previously learned the relationship between at least the number of evacuees and consumption information. Specifically, the estimation unit 120 inputs the acquired evacuee information into the learning model. The estimation unit 120 acquires the consumption information output by the learning model as consumption information corresponding to the evacuation shelter. Then, the estimation unit 120 estimates the shortage or surplus of supplies based on the consumption information corresponding to the evacuation shelter and the existing supply information.

The estimation unit 120 may estimate the shortage or surplus of supplies required at the evacuation shelter by using a learning model that has previously learned the relationship between the number of evacuees and the number of stockpiled supplies, and the shortage or surplus of supplies. In this case, the estimation unit 120 estimates the shortage or surplus of supplies by inputting evacuee information and existing supply information into the learning model.

The method for estimating shortages or surpluses of materials is not limited to the above example, and various methods may be used.

In this way, the estimation unit 120 estimates the surplus or shortage of supplies required for the evacuation shelter based on the existing supply information and the evacuee information. The estimation unit 120 is an example of an estimation means.

The output control unit 130 causes the output device to output information indicating the estimated surplus or shortage. The output device is a device that is connected to the evacuation support device 100 so as to be able to communicate wirelessly or via a wire. The output device is, for example, a device equipped with a display. The output control unit 130 is an example of an output control means.

Next, an example of the operation of the evacuation support device 100 will be described with reference to FIG. 3. Note that in this disclosure, each step in the flowchart will be represented by a number assigned to each step, such as "S1."

Figure 3 is a flowchart explaining an example of the operation of the evacuation support device 100. The acquisition unit 110 acquires existing supplies information indicating supplies present at the evacuation shelter and evacuee information indicating information on evacuees at the evacuation shelter from the management device 200 installed at the evacuation shelter via an artificial satellite (S1). The estimation unit 120 estimates the surplus or shortage of supplies required for the evacuation shelter based on the existing supplies information and the evacuee information (S2). The output control unit 130 then causes the output device to output information indicating the estimated surplus or shortage of supplies (S3).

In this way, the evacuation support device 100 of the first embodiment acquires existing material information indicating materials present at the evacuation shelter and evacuee information indicating information on evacuees at the evacuation shelter from the management device 200 installed at the evacuation shelter via an artificial satellite. Then, the evacuation support device 100 estimates the surplus or shortage of materials required for the evacuation shelter based on the existing material information and the evacuee information, and outputs information indicating the estimated surplus or shortage of materials to an output device.

When a specific device acquires information transmitted from an evacuation shelter using only terrestrial communication networks such as base stations and relay stations, if the base station or the like is damaged by a disaster, the specific device cannot stably acquire information. In contrast, the evacuation support device 100 acquires evacuee information, etc. from the management device 200 installed at the evacuation shelter via an artificial satellite. This allows the evacuation support device 100 to acquire information stably even during a disaster, compared to when only terrestrial communication networks are used. Therefore, the evacuation support device 100 can estimate the surplus or shortage of materials more accurately. Therefore, the user of the evacuation support device 100 can take appropriate evacuation measures, such as ordering materials based on the estimated surplus or shortage of materials. In other words, the evacuation support device 100 can support evacuation measures.

Second Embodiment
Next, an evacuation support device according to a second embodiment will be described. In the second embodiment, a further example of the evacuation support device described in the first embodiment will be described. Note that some of the contents overlapping with the first embodiment will not be described.

Figure 4 is a schematic diagram showing an example of the configuration of the evacuation support system 1000. In the example of Figure 4, the evacuation support system 1000 includes an evacuation support device 100 and a management device 200. The evacuation support device 100 and the management device 200 are communicatively connected via a wireless or wired network. In this case, the evacuation support device 100 and the management device 200 are communicatively connected at least via an artificial satellite. Note that in this embodiment, as in the example of Figure 1, the management device 200 is installed in an evacuation shelter, and the evacuation support device 100 is installed in a local government facility.

The management device 200 may be communicatively connected to various devices. In the example of FIG. 4, the management device 200 is communicatively connected to a computer having a reading device capable of reading an IC (Integrated Circuit) chip, and a camera. Note that the devices communicatively connected to the management device 200 are not limited to this example.

[Details of the evacuation support system 1000]
Fig. 5 is a block diagram showing an example of a functional configuration of the evacuation assistance system 1000. As shown in Fig. 5, the management device 200 includes a reception unit 210 and a transmission control unit 220. The management device 200 further includes a storage device 230. Note that the storage device 230 may be an external device connected to the management device 200 so as to be able to communicate with the management device 200.

The reception unit 210 receives the input of evacuee information. At this time, the reception unit 210 may receive the input of evacuee information using various methods. For example, the user of the management device 200 may input the evacuee information using an input device, whereby the reception unit 210 receives the evacuee information.

The reception unit 210 may also receive information estimated from the captured image as evacuee information. In this case, the management device 200 is connected to the camera so that it can communicate with the camera. That is, the camera is installed at a shelter. For example, the camera is installed at the entrance of the shelter and captures each of the evacuees. Then, the camera transmits the captured image to the management device 200. The reception unit 210 estimates the gender and age of the person appearing in the captured image. The method of estimating the gender and age of the person from the captured image may be a known method. For example, the reception unit 210 detects a face area from the captured image and extracts features in the face area. Then, the reception unit 210 uses the extracted features to estimate the gender and age of the person appearing in the captured image based on a learning model that has learned the relationship between the features and the gender and age. In this way, the reception unit 210 may receive information on the gender and age of the evacuee estimated from the captured image as evacuee information. In this case, the evacuee information includes information in which gender and age are associated. The number of pieces of information in which gender and age are associated can be counted as the number of evacuees. The camera may also estimate a person's gender and age from the captured image. In this case, the camera transmits the estimation result to the management device 200.

The reception unit 210 may also accept the result of the biometric authentication as the evacuee information. For example, when face authentication is performed as the biometric authentication, the management device 200 is connected to a camera so as to be able to communicate with it. The camera captures each of the evacuees. Then, the camera transmits the captured image to the management device 200. The reception unit 210 performs face authentication using the captured image. The face authentication method may be a known method. For example, the reception unit 210 performs face authentication by matching a feature amount extracted from a face image included in the captured image with a feature amount included in a face image included in a face image database. The face image database is a database in which a face image or a feature amount extracted from a face image is associated with personal information. The personal information includes a person's name, age, sex, address, etc. The face image database is stored in, for example, the storage device 230. The reception unit 210 accepts the personal information of a person who matches the match as evacuee information. Note that face authentication may be performed in the camera. In this case, the face image database is stored in the camera or a device connected to the camera so as to be able to communicate with it. The camera then transmits the personal information associated with the matching facial image to the management device 200.

In the above example, biometric authentication is not limited to face authentication. Biometric authentication may be an authentication method that uses fingerprints, palm prints, veins, irises, etc. In this case, the devices that detect each piece of biometric information are connected to the management device 200 so that they can communicate with each other.

The reception unit 210 may also accept information that can be read from an official certificate as the evacuee information. An official certificate refers to a document that has personal information about a person and can be used to identify the person. Examples of official certificates include a My Number card and a driver's license. For example, a camera that is communicably connected to the management device 200 takes a picture of the official certificate. The camera then transmits the captured image to the management device 200. The reception unit 210 reads the personal information written on the official certificate from the captured image. The reception unit 210 then accepts the read personal information as the evacuee information. A method for reading the information written on the official certificate from the captured image may be a known character recognition method. An example of a character recognition method is OCR (Optical Character Recognition). Character recognition may be performed in the camera. In this case, the camera transmits the read personal information to the management device 200.

Furthermore, if the official certificate is equipped with an IC chip storing personal information, the reception unit 210 may accept the personal information read from the IC chip as evacuee information. In this case, the management device 200 is communicatively connected to a computer having a reading device capable of reading the IC chip. For example, when the official certificate is held up to the reading device, the reading device reads the personal information from the IC chip. The method of reading information from the IC chip is realized by a technology such as NFC (Near Field Communication). The read personal information is then transmitted to the management device 200 via the computer. The reception unit 210 accepts the transmitted personal information as evacuee information.

In this way, the reception unit 210 receives input of evacuee information about evacuees in evacuation shelters. The reception unit 210 is an example of a reception means.

The transmission control unit 220 transmits various types of information. The transmitted information is sent to the evacuation support device 100 via an artificial satellite. Hereinafter, the transmission control unit 220 transmitting information to the artificial satellite and thereby sending information to the evacuation support device 100 will be described as simply transmitting information to the evacuation support device 100.

The transmission control unit 220 transmits the existing goods information and the evacuee information to the evacuation support device 100. The existing goods information is stored in advance. For example, the existing goods information is stored in the storage device 230. The transmission control unit 220 reads out the existing goods information from the storage device 230 and transmits the read out existing goods information to the evacuation support device 100. FIG. 6 is a diagram showing an example of existing goods information. The existing goods information is information in which the type of goods and the quantity are associated with each other. In the example of FIG. 6, for example, the quantity "100" is associated with the type of goods "water". This indicates that 100 units of water (for example, 100 plastic bottles) are stockpiled at the evacuation shelter.

The transmission control unit 220 also transmits the evacuee information received by the reception unit 210 to the evacuation support device 100.

The evacuee information and existing supplies information are associated with evacuee identification information that identifies the evacuee shelter. That is, the evacuation support device 100 acquires the evacuee information and existing supplies information along with the evacuee identification information. The evacuation shelter identification information includes, for example, the ID (IDentifier) of the evacuee shelter. Furthermore, the evacuation shelter identification information may include the name of the evacuee shelter, location information, and the name of the local government that manages the evacuee shelter. The evacuation support device 100 can identify which evacuee shelter the acquired evacuee information and existing supplies information is from.

In this way, the transmission control unit 220 transmits the evacuee information and the pre-stored existing supplies information. The transmission control unit 220 is an example of a transmission control means.

Returning to the explanation of FIG. 5, the evacuation support device 100 includes an acquisition unit 110, an estimation unit 120, and an output control unit 130.

The acquisition unit 110 acquires existing goods information and evacuee information from the management device 200 via an artificial satellite.

The estimation unit 120 estimates the surplus or shortage of supplies required at the evacuation shelter. First, the estimation unit 120 counts the number of evacuees based on the evacuee information. At this time, the estimation unit 120 may also count the number of evacuees by attribute. For example, the estimation unit 120 may count the number of evacuees by gender, or by age.

For example, assume that correspondence information that associates the number of evacuees with consumption information is stored in a storage device possessed by the evacuation support device 100. The estimation unit 120 identifies the consumption information that corresponds to the counted number of people. The estimation unit 120 may then estimate the surplus or shortage of supplies based on the difference between the expected consumption number of supplies indicated in the identified consumption information and the number of supplies indicated in the existing supply information.

At this time, the estimation unit 120 may estimate the shortage or surplus of supplies using information on the number of evacuees tallied for each attribute. For example, it is expected that the more women there are, the more sanitary products will be consumed. Also, for example, it is expected that the more children under the age of three there are, the more powdered milk will be consumed. Therefore, by estimating the shortage or surplus of supplies according to the number of people for each attribute, it is possible to more accurately estimate the shortage or surplus of supplies.

In this case, the corresponding information includes information that associates the number of people for each attribute with the number of supplies expected to be consumed in a specified period. For example, the corresponding information indicates the expected number of sanitary products to be consumed corresponding to each of the cases, such as when there are fewer than 10 women and when there are between 10 and 20 women. The estimation unit 120 identifies the expected number of sanitary products to be consumed corresponding to the total number of women.

In addition, the method of estimating the shortage or surplus of supplies is not limited to the above example. For example, the estimation unit 120 may identify consumption information at an evacuation shelter using a learning model in which the relationship between the number of evacuees for each attribute and consumption information has been learned in advance. In this case, the estimation unit 120 inputs the number of evacuees for each attribute tallied in the learning model. The estimation unit 120 identifies the consumption information output by the learning model as consumption information corresponding to the evacuation shelter. Then, the estimation unit 120 estimates the shortage or surplus of supplies based on the identified consumption information and existing supply information.

The estimation unit 120 may estimate the shortage or surplus of supplies required at the evacuation shelter by using a learning model that has previously learned the relationship between the number of evacuees for each attribute, the number of stockpiled supplies, and the shortage or surplus of supplies. In this case, the estimation unit 120 estimates the shortage or surplus of supplies by inputting the aggregated number of evacuees for each attribute and existing supply information into the learning model.

Figure 7 is a diagram showing an example of information indicating a shortage or surplus of materials. In the example of Figure 7, information is shown that associates the type of material, the quantity of existing materials, the expected consumption number, and the shortage or surplus of materials. For example, for "water," the quantity of existing materials is "100," and the expected consumption number is "200." The shortage or surplus of "water" is shown as "-100." In other words, it is shown that the quantity of "water" is short by 100.

The output control unit 130 causes the output device to output information indicating the estimated shortage or surplus of materials. For example, the output control unit 130 causes a display to display information indicating the shortage or surplus of materials. Note that the output control unit 130 may output the shortage or surplus of all materials as shown in FIG. 7, or may output the shortage or surplus of some materials. For example, the output control unit 130 may output the type of material and the quantity that is in shortage for each material that is in shortage.

[Example of Operation of Evacuation Assistance System 1000]
Next, an example of the operation of the evacuation assistance system 1000 will be described with reference to Fig. 8. Fig. 8 is a sequence diagram showing an example of the operation of the evacuation assistance system 1000.

First, the reception unit 210 of the management device 200 receives evacuee information (S101). At this time, as described above, the evacuee information may be any of information input by a user of the management device 200, information estimated from a captured image, information based on the results of biometric authentication, and information that can be read from an official certificate. The transmission control unit 220 reads out the existing supplies information from the storage device 230 (S102). Then, the transmission control unit 220 transmits the evacuee information and the existing supplies information to the evacuation support device 100 (S103). At this time, the evacuee information and the existing supplies information are transmitted to the evacuation support device 100 via an artificial satellite.

The acquisition unit 110 of the evacuation support device 100 acquires evacuee information and existing supplies information via an artificial satellite (S104). The estimation unit 120 counts the number of evacuees based on the evacuee information (S105). At this time, the estimation unit 120 may also count the number of evacuees by attribute. The estimation unit 120 also estimates the surplus or shortage of supplies (S106). Then, the output control unit 130 causes the output device to output information indicating the estimated surplus or shortage of supplies (S107).

Note that the operation of the evacuation support system 1000 is not limited to the above example. For example, the order of the processing of S101 and S102 may be reversed.

Thus, the evacuation support system 1000 of the second embodiment includes a management device 200 and an evacuation support device 100. The management device 200 is installed at an evacuation shelter, accepts input of evacuee information related to evacuees at the evacuation shelter, and transmits the evacuee information and pre-stored existing supplies information indicating supplies present at the evacuation shelter. The evacuation support device 100 also acquires the existing supplies information and evacuee information from the management device 200 via an artificial satellite. The evacuation support device 100 then estimates the surplus or shortage of supplies required for the evacuation shelter based on the existing supplies information and the evacuee information, and causes an output device to output information indicating the estimated surplus or shortage of supplies.

When information transmitted from evacuation shelters is acquired only using terrestrial communication networks such as base stations and relay stations, if the base stations are damaged by a disaster, the information cannot be acquired stably. In contrast, the evacuation support device 100 acquires evacuee information, etc. from the management device 200 installed at the evacuation shelter via an artificial satellite. This allows the evacuation support device 100 to acquire information stably even during a disaster, compared to when only terrestrial communication networks are used. Therefore, the evacuation support device 100 can estimate the surplus or shortage of materials more accurately. Therefore, the user of the evacuation support device 100 can take appropriate evacuation measures, such as ordering materials based on the estimated surplus or shortage of materials. In other words, the evacuation support device 100 can support evacuation measures.

[Modification 1]
The evacuation assistance device 100 may estimate the shortage or surplus of supplies using further information.

For example, the acquisition unit 110 may acquire delivery schedule information. The delivery schedule information is information indicating supplies that are scheduled to be delivered to an evacuation shelter. For example, the delivery schedule information is information in which the type and quantity of supplies that are scheduled to be delivered to the evacuation shelter are associated with each other. Furthermore, the delivery schedule information includes evacuation shelter identification information of the delivery destination evacuation shelter. The delivery schedule information is stored in a storage device possessed by the evacuation support device 100 or in an external device communicably connected to the evacuation support device 100. The acquisition unit 110 acquires the delivery schedule information based on the evacuation shelter identification information acquired from the management device 200. For example, the acquisition unit 110 acquires delivery schedule information that includes the same evacuation shelter identification information as the acquired evacuation shelter identification information. Note that the acquisition unit 110 may acquire the delivery schedule information without using an artificial satellite.

The estimation unit 120 estimates the shortage or surplus of supplies based on the existing supply information, the evacuee information, and the delivery schedule information. For example, assume that correspondence information that associates the number of evacuees with consumption information is stored in a storage device possessed by the evacuation support device 100. The estimation unit 120 identifies the consumption information that corresponds to the total number of people. The estimation unit 120 may then estimate the shortage or surplus of supplies by subtracting the sum of the number of supplies indicated in the existing supply information and the number of supplies indicated in the delivery schedule information from the expected consumption number of supplies indicated in the identified consumption information.

In addition, when the shortage or surplus of supplies is output using a learning model, the estimation unit 120 may estimate the shortage or surplus of supplies required for the evacuation shelter by subtracting the number of supplies indicated in the delivery schedule information from the shortage or surplus of supplies output by the learning model.

In this way, the evacuation support device 100 of variant example 1 acquires delivery schedule information indicating supplies that are scheduled to be delivered to the evacuation shelter, and estimates the surplus or shortage of supplies required for the evacuation shelter based on the existing supplies information, the evacuee information, and the delivery schedule information.

Supplies may already have been ordered for delivery to evacuation shelters. In this case, there may be an oversupply depending on the type of supply. In response to this, the evacuation support device 100 of variant 1 can estimate the surplus or shortage of supplies by taking into account delivery schedule information indicating the supplies that are scheduled to be delivered. This allows the evacuation support device 100 of variant 1 to estimate the appropriate quantity of supplies.

Third Embodiment
Next, an evacuation support device according to a third embodiment will be described. In the third embodiment, an example of estimating a specific type of material will be described. Note that some of the contents overlapping with the first and second embodiments will not be described.

[Details of the evacuation support system 1001]
Fig. 9 is a block diagram showing an example of a functional configuration of an evacuation support system 1001. In the example of Fig. 9, the evacuation support system 1001 includes an evacuation support device 101 and a management device 201. As in the first and second embodiments, the evacuation support device 101 and the management device 201 are communicatively connected via a wireless or wired network. At this time, the evacuation support device 101 and the management device 201 are communicatively connected at least via an artificial satellite.

In addition to the processing of the management device 200, the management device 201 may perform the processing described below.

The management device 201 includes a reception unit 211 and a transmission control unit 221. The management device 201 further includes a storage device 230.

The reception unit 211 may receive input of identification information that identifies an evacuee. The identification information may be a predetermined character string or code string. In this case, for example, the user of the management device 201 or an evacuee may input the identification information using an input device, whereby the reception unit 211 may receive the identification information.

The identification information may be certification information included in the public certificate. The certification information is information that indicates the validity of the public certificate. For example, the certification information is an electronic certificate issued by an external certification authority. In a public certificate that includes an IC chip, such as a My Number card, an electronic certificate is included in the IC chip. The certification information may include personal information written in the public certificate.

The management device 201 is communicably connected to a computer having a reading device capable of reading IC chips. If the identification information is certification information, an official certificate is held up to the reading device, which then reads the certification information from the IC chip. The read certification information is then transmitted to the management device 201 via the computer. The reception unit 211 receives the transmitted certification information as identification information.

The reading device may read the certification information by holding a mobile terminal having a public certificate function over it. For example, a mobile terminal equipped with the above-mentioned electronic certificate becomes a terminal having a public certificate function. Such a terminal having a public certificate function is sometimes called a public certificate integrated terminal. For example, a mobile terminal equipped with an electronic certificate for a My Number card has the My Number card function and is sometimes called a My Number card integrated terminal. The reading device may read the certification information from such a public certificate integrated terminal, for example.

The transmission control unit 221 transmits the identification information to the evacuation support device 101. For example, the transmission control unit 221 transmits at least one piece of identification information of an evacuee in an evacuation shelter to the evacuation support device 101. At this time, the transmission control unit 221 transmits, for example, the identification information together with the evacuation shelter identification information. The transmission control unit 221 may also transmit the identification information together with at least one of existing supplies information and evacuee information.

In addition to the processing of the evacuation support device 100, the evacuation support device 101 may perform the processing described below.

The evacuation support device 101 includes an acquisition unit 111, an estimation unit 121, and an output control unit 130. The acquisition unit 111 acquires identification information. More specifically, the acquisition unit 111 acquires the identification information of evacuees from the management device 201 via an artificial satellite.

The estimation unit 121 acquires medical information based on the identification information. Medical information refers to information about medical procedures that a person has received. For example, medical information includes information about medicines prescribed for a person. An example of information about medicines prescribed for a person is a medicine notebook. Without being limited to this, medical information may also include information about hospitals that a person visits, a person's medical history, and information about injuries and illnesses currently being treated.

The medical information is stored in association with the identification information. For example, there is a database in which the medical information is associated with the identification information. The database is stored in an external device communicatively connected to the evacuation support device 101. The database may be owned by the evacuation support device 101. The estimation unit 121 uses the identification information acquired by the acquisition unit 111 to acquire medical information that matches the identification information from the database. At this time, the medical information is acquired based on the identification information accepted by the evacuation shelter management device 201. In other words, the acquired medical information is information regarding the medical treatment received by the evacuee.

The estimation unit 121 then uses the acquired medical information to estimate the surplus or shortage of supplies required for the evacuation shelter. For example, assume that the estimation unit 121 acquires information on medicines prescribed for evacuees as medical information. At this time, the estimation unit 121 estimates the number of medicines (estimated required number) that are indicated in the medical information and will be consumed in a specified period. For example, if the specified period is one week, the estimation unit 121 estimates the number of medicines consumed in one week. If the medicine is taken twice a day, one tablet, the estimation unit 121 estimates that 14 tablets of the medicine will be consumed. Then, the estimation unit 121 estimates the surplus or shortage of the medicine by taking the difference between the number of the medicine included in the existing material information and the estimated estimated required number of the medicine. At this time, if information on the medicine is not indicated in the existing material information, the estimation unit 121 may determine that the estimated required number of the medicine is insufficient. Note that the estimation method is not limited to this example, and once the necessary medicine is identified, the estimation unit 121 may estimate that a predetermined number is insufficient. In this way, the estimation unit 121 may estimate the surplus or shortage of supplies, including medicines, needed at the evacuation shelter.

Furthermore, the example of estimating the shortage or surplus of supplies based on medical information is not limited to this example. For example, assume that the estimation unit 121 acquires information indicating an injury being treated as medical information. At this time, the estimation unit 121 estimates the shortage or surplus of medical supplies necessary to treat the injury. For example, if there is an evacuee receiving treatment for a fracture, the estimation unit 121 estimates the shortage or surplus of medical supplies such as gauze, bandages, and tape.

In this way, the estimation unit 121 acquires medical information, which is information related to the medical treatment received by the evacuee and is associated with the identification information based on the acquired identification information. The estimation unit 121 then further uses the medical information to estimate the supplies, including medical equipment, that are required for the evacuation shelter.

[Example of operation of evacuation support system 1001]
Next, an example of the operation of the evacuation assistance system 1001 will be described with reference to Fig. 10. Fig. 10 is a sequence diagram showing an example of the operation of the evacuation assistance system 1001.

First, the reception unit 211 of the management device 201 receives input of identification information (S201). For example, the reception unit 211 receives certification information read from a public certificate as identification information. The reception unit 211 also receives evacuee information (S202). The transmission control unit 221 reads out existing material information from the storage device 230 (S203). The transmission control unit 221 then transmits the evacuee information, existing material information, and identification information to the evacuation support device 101 (S204).

The acquisition unit 111 of the evacuation support device 101 acquires evacuee information, existing supplies information, and identification information via an artificial satellite (S205). The estimation unit 121 counts the number of evacuees based on the evacuee information (S206). The estimation unit 121 also acquires medical information based on the identification information (S207). The estimation unit 121 then estimates the surplus or shortage of supplies (S208). The output control unit 130 then causes the output device to output information indicating the estimated surplus or shortage of supplies (S209).

In this way, the evacuation support device 101 of the third embodiment acquires the identification information of evacuees from the management device 201 via an artificial satellite. Then, based on the acquired identification information, the evacuation support device 101 acquires medical information associated with the identification information, which is information regarding medical treatments received by the evacuees, and further uses the medical information to estimate the surplus or shortage of materials, including medical supplies, required for the evacuation shelter.

In the third embodiment, for example, the medical information includes information regarding medicines prescribed for evacuees. At this time, the evacuation support device 101 estimates the surplus or shortage of supplies, including medicines, required at the evacuation shelter.

This allows the evacuation support device 101 to also output information indicating the medical supplies required. Furthermore, because the evacuation support device 101 uses information regarding the medical treatments that evacuees actually received, it can more accurately estimate the surplus or shortage of materials, including medical supplies.

[Modification 2]
Information indicating estimated shortages or surpluses of supplies, aggregated information on evacuees, etc. can be used to generate evacuation order information.

Evacuation order information is information to encourage residents to evacuate. Evacuation order information includes information indicating the type of disaster that has occurred, the location of the disaster, and information indicating areas where evacuation is encouraged. Evacuation order information is output via the Internet, television broadcasts, radio broadcasts, and the like. For example, evacuation order information is output to mobile devices such as smartphones and mobile phones, and to televisions.

Figure 11 is a block diagram showing an example of the functional configuration of the evacuation support system 1001 of variant example 2. As shown in Figure 11, the evacuation support device 101 may include a generation unit 140. The generation unit 140 is an example of a generation means.

The generating unit 140 generates evacuation order information. At this time, the generating unit 140 generates evacuation order information indicating the shelter to which the evacuees should evacuate based on the collected evacuee information. For example, the generating unit 140 identifies, among multiple evacuation shelters, a shelter where the number of evacuees is less than the number set as the capacity. Then, the generating unit 140 generates evacuation order information indicating to evacuate to the identified evacuation shelter.

The generating unit 140 may also generate evacuation instruction information indicating a shelter to which the person should evacuate based on information indicating the estimated shortage or surplus of supplies. For example, the generating unit 140 identifies, among multiple shelters, a shelter where the type and number of supplies that are in short supply are less than a predetermined threshold. The generating unit 140 then generates evacuation instruction information indicating to evacuate to the identified shelter.

In this way, the evacuation support device 101 generates evacuation instruction information indicating the evacuation shelter to which the residents should evacuate, based on at least one of the information indicating the estimated shortage or surplus of supplies and the evacuee information. This allows the evacuation support device 101 to inform residents who have not yet evacuated of evacuation shelters with a large shortage of supplies or shelters that do not have many evacuees.

<Example of hardware configuration of evacuation support device>
