The date / time information normally includes date information indicating a date and time information indicating a time. Date information usually includes the year as well as the month and day. The user identifier is, for example, a telephone number or a mail address.

  The disaster related information is usually a character string (one or more characters). The disaster-related information may be an image (photograph), for example. That is, the situation accompanying the occurrence of a disaster indicated by the disaster-related information is usually indicated by a character string or an image.

  The server identifier storage unit 1102 stores a server identifier for identifying the server device 11. The server identifier is not particularly limited as long as it can identify the server device 11, and its format and style are not limited. The server identifier is, for example, an SSID (Service Set Identifier), an IP address, a URL, or a domain name.

  The server position information storage unit 1103 stores server position information that is position information indicating the current position of the server device 11. The process of storing the server location information in the server location information storage unit 1103 does not matter. For example, the server position information is read by a device that reads position information received from a satellite navigation system (such as a GPS receiver) or a mobile communication base station, or a QR code (registered trademark) indicating the position information. Position information acquired by reading the position information, position information input by the user, and the like.

  The server reception unit 1104 receives one or more disaster related information. The server reception unit 1104 also receives a disaster-related information request instruction that is an instruction to request disaster-related information. These “receptions” are usually receptions from two or more terminal devices 12. Also, these two pieces of information are usually not received at the same time but are received separately.

  The disaster-related information request instruction usually indicates that disaster-related information is requested, the location of the transmitting device, the distance from the transmitting device, the date and time range, the number of cases (number of disaster-related information), the type of content, etc. Have information. Also, a disaster-related information request instruction is normally associated with a device identifier that identifies the device that transmitted the disaster-related information request instruction.

It may be. The server reception unit 1104 may receive a disaster-related information request instruction associated with a server identifier from one or more other server apparatuses 11.

  The server accumulation unit 1105 accumulates one or more disaster related information received by the server reception unit 1104 in the server storage unit 1101. At this time, the server storage unit 1105 may acquire date and time information indicating the date and time, and store one or more disaster related information in association with the date and time information.

  The server integration unit 1106 integrates two or more disaster related information stored in the server storage unit 1101. The “integrating” usually means that two or more disaster-related information are combined into one. Further, the “one” may include “one or more”. “To make one” means to leave one disaster-related information among two or more disaster-related information, or to select one disaster-related information from two or more disaster-related information.

  For example, the server integration unit 1106 integrates two or more disaster-related information stored in the server storage unit 1101 that have the same disaster status indicated by the disaster-related information. In other words, the server integration unit 1106 integrates two or more disaster-related information having the same contents. Specifically, for example, the server integration unit 1106 performs natural language processing on two or more disaster-related information stored in the server storage unit 1101, and the situation of occurrence of a disaster indicated by the two or more disaster-related information is the same. It is determined whether or not, and two or more disaster related information that is the same is integrated.

  For example, the server integration unit 1106 calculates the similarity between one disaster related information of two or more disaster related information stored in the server storage unit 1101 and one or more remaining disaster related information. A method for calculating the similarity will be described later. Then, the server integration unit 1106 integrates two or more disaster-related information that are so high that the degree of similarity satisfies a predetermined condition (hereinafter, similar condition as appropriate).

  For example, the server integration unit 1106 vectorizes each of two or more disaster-related information stored in the server storage unit 1101, and uses the vector to use one disaster-related information and the remaining one or more disaster-related information. The similarity with the information is calculated. In addition, since vectorization of disaster related information, the calculation method of the similarity using the said vector, etc. are well-known, description is abbreviate | omitted.

  In addition, the server integration unit 1106 performs, for example, morphological analysis of each of two or more disaster-related information stored in the server storage unit 1101, and the independent words included in one disaster-related information and the remaining one or more disasters The number of the same independent words, the position of the same independent words in each disaster related information, and the like are calculated by comparing with the independent words included in the related information. The “number of independent words” includes “the ratio of independent words”. The “position” is usually a position from the front (first character). Then, the server integration unit 1106 uses the number of the same independent words, the positions of the same independent words, and the like, and the similarity between the one disaster related information and the remaining one or more disaster related information Is calculated. Note that the method and procedure of morphological analysis, the number of identical independent words, the method of calculating the similarity using the same independent word position, and the like are well-known, and will not be described.

  Note that the method and procedure for determining whether or not the contents of the two disaster-related information are the same are irrelevant. That is, the server integration unit 1106 may determine whether or not the contents of the two disaster-related information are the same by a method or procedure other than the method or procedure described above.

Further, when integrating two or more disaster-related information having the same contents (hereinafter, appropriately two or more disaster-related information to be integrated), the server integration unit 1106 uses, for example, the following information: Thus, two or more disaster related information to be integrated may be integrated.
(A) Information amount possessed by disaster-related information (b) Date and time information associated with disaster-related information (c) Location information associated with disaster-related information

  The “amount of information” in (a) is, for example, the number of characters of the disaster-related information, the number of independent words that the disaster-related information has, the ratio of independent words to the morphemes that the disaster-related information has. When the information amount (a) is used, the server integration unit 1106, for example, among the two or more disaster-related information to be integrated, the information amount satisfies one or more predetermined conditions (hereinafter, information amount conditions as appropriate) Leave disaster related information. The information amount condition is, for example, “being the maximum”, “being the minimum”, “being a predetermined amount of information or more”, and the like.

  When the date / time information of (b) is used, the server integration unit 1106, for example, among the two or more disaster-related information to be integrated, the date / time indicated by the date / time information satisfies a predetermined condition (hereinafter, date / time condition as appropriate). Leave one or more disaster related information to satisfy. The date / time condition is, for example, “being the latest”, “being within a predetermined date / time range”, or the like.

  When the position information (c) is used, the server integration unit 1106 has a predetermined condition (for example, the distance from the server device 11 that can be calculated using the position information among two or more disaster-related information to be integrated). Hereinafter, one or more disaster related information satisfying the distance condition) is appropriately left. The distance condition is, for example, “being shortest” or “being within a predetermined distance”. In this case, the server integration unit 1106 normally uses the server location information stored in the server location information storage unit 1103 and the location information associated with each of the two or more disaster-related information to be integrated. Is calculated. Note that a method and a procedure for calculating the distance between the positions indicated by the position information using the two position information are well known, and thus detailed description thereof is omitted. Moreover, it is preferable that the location information is occurrence location information associated with disaster-related information.

  Further, the server integration unit 1106 may leave one or more disaster-related information satisfying a condition obtained by combining the three conditions (a) to (c).

  In addition, the server integration unit 1106 performs, for example, the following process for the process of leaving one or more disaster related information satisfying the predetermined condition.

(Processing example 1)
(1) Delete disaster-related information other than one or more disaster-related information satisfying a predetermined condition from the server storage unit 1101.

(Processing example 2)
(1) Obtain disaster-related information other than one or more disaster-related information satisfying a predetermined condition from the server storage unit 1101.
(2) Delete two or more disaster-related information to be integrated from the server storage unit 1101.
(3) The disaster-related information acquired in (1) is accumulated in the server storage unit 1101.

  Further, the server integration unit 1106 may integrate two or more disaster-related information using, for example, a user identifier associated with the disaster-related information. In this case, the server integration unit 1106, for example, extracts two or more disaster-related information having the same user identifier from the two or more disaster-related information to be integrated, as described above. Integrate using Further, the server integration unit 1106 may integrate two or more disaster related information using other information associated with the disaster related information, for example.

  The timing at which the server integration unit 1106 integrates one or more disaster related information stored in the server storage unit 1101 is, for example, immediately after the server storage unit 1105 stores one or more disaster related information in the server storage unit 1101. Or every elapse of a predetermined time (regular).

  The server acquisition unit 1107 acquires one or more disaster related information from the server storage unit 1101. The server acquisition unit 1107 normally acquires one or more disaster related information corresponding to the disaster related information request instruction in response to the reception of the disaster related information request instruction by the server receiving unit 1104. That is, the server acquisition unit 1107 normally determines whether or not the server reception unit 1104 has received a disaster-related information request instruction, and when received, the server acquisition unit 1107 has one or more disaster-related information corresponding to the disaster-related information request instruction. To get.

  The disaster-related information request instruction indicates, for example, the request for disaster-related information, the location of the transmitting device, the distance from the transmitting device, the date and time range, the number of cases (number of disaster-related information), the type of content, etc. Have information. Therefore, the server acquisition unit 1107 acquires one or more disaster related information that matches these information included in the disaster related information request instruction.

  For example, when the disaster-related information request instruction includes information indicating the position of the apparatus that transmitted the instruction (hereinafter, apparatus position information), the server acquisition unit 1107, for example, The distance from the position indicated by the position information associated with each of the two or more disaster-related information stored in the server storage unit 1101 is calculated. Then, the server acquisition unit 1107 determines whether or not the distance satisfies a predetermined condition. Then, the server acquisition unit 1107 acquires two or more disaster related information determined to satisfy the condition. The predetermined condition is, for example, the above-described distance condition. Note that the disaster-related information acquisition method and procedure when the disaster-related information request instruction has other information are self-explanatory and will not be described.

  Further, the server acquisition unit 1107, for example, when a later-described other server communication availability determination unit 1109 determines that communication with one or more other server devices 11 is possible, or a later-described backbone server communication availability determination unit. When the 1110 determines that communication with the core server device 13 is possible, one or more disaster-related information that matches a predetermined condition may be acquired from the server storage unit 1101 according to the determination. . The predetermined condition may be, for example, the above-mentioned distance condition or “obtain all”.

  The server transmission unit 1108 associates and transmits the server identifier stored in the server identifier storage unit 1102 and the server location information stored in the server location information storage unit 1103. The “transmission” is usually so-called broadcast transmission. “Broadcast transmission” is, for example, transmission similar to transmission of a beacon signal by a wireless LAN access point.

  When the server acquisition unit 1107 acquires one or more disaster-related information, the server transmission unit 1108 transmits the one or more disaster-related information to the terminal device 12 and one or more other server devices 11. That is, the server transmission unit 1108 transmits the one or more disaster-related information in response to the acquisition of the one or more disaster-related information by the server acquisition unit 1107. The server transmission unit 1108 normally transmits one or more disaster related information in the following cases.

  (1) When the server acquisition unit 1107 acquires one or more disaster-related information in response to the reception of a disaster-related information request instruction by the server reception unit 1104

  In this case, the server transmission unit 1108 has the terminal device 12, the server device 11, or the backbone server device 13 identified by each of the terminal identifier, the server identifier, or the backbone server identifier associated with the disaster-related information request instruction. The one or more disaster related information is transmitted.

  (2) When the server acquisition unit 1107 acquires one or more disaster-related information in response to a determination that communication with one or more other server apparatuses 11 is possible by the other server communication availability determination unit 1109 described later

  In this case, the server transmission unit 1108 normally transmits to one or more other server apparatuses 11 that the other server communication enable / disable determination unit 1109 described later determines that communication is possible.

  (3) When the server acquisition unit 1107 acquires one or more disaster-related information according to the determination that the communication with the backbone server device 13 is possible by the later-described backbone server communication availability determination unit 1110

  In this case, the server transmission unit 1108 normally transmits to the backbone server device 13 that the backbone server communication availability determination unit 1110 described later determines that communication is possible.

(Concrete example)
Next, a specific example of the operation of the disaster information system 1 will be described. In this specific example, the server device 11 is assumed to be a server that operates a bulletin board service in each region (hereinafter referred to as a regional server). The terminal device 12 is installed with application software for inputting disaster related information, transmitting the disaster related information to the server device 11, receiving disaster related information from the server device 11, and displaying the disaster related information. It is assumed that the mobile terminal device (hereinafter referred to as a mobile terminal) is used. The backbone server device 13 is assumed to be a server that manages disaster-related information collected from one or more server devices 11 (hereinafter referred to as a backbone server). In addition, one or more regional servers, one or more portable terminals, a user who operates each portable terminal, and the like are appropriately assigned to the regional server A, the regional server B, the portable terminal A, the portable terminal B, the user A, and the user B. And so on. In addition, the server device 11 transmits the server identifier associated with the server position information within a radius of 50 m from the current position.

(Example 1: Disaster)
In this example, as shown in FIG. 9, in a situation where a disaster has occurred and the infrastructure line has become unusable, the user can send disaster-related information to a regional server installed in each region or be installed in each region. An example in which a user browses disaster-related information stored in a regional server will be described.

  First, the server transmission unit 1108 of the regional server A installed in the region A has the server identifier “LocalServerA” stored in the server identifier storage unit 1102 and the server location information stored in the server location information storage unit 1103. And the two pieces of information are associated with each other and transmitted.

  Next, it is assumed that the user A enters the range of 50 m from the regional server A in the state where the portable terminal A is held. Then, the terminal reception unit 1206 of the mobile terminal A receives the server identifier and server location information transmitted by the regional server device A.

  Next, the transmission destination server determination unit 1207 of the mobile terminal A acquires one server identifier from one or more server identifiers received by the terminal reception unit 1206. In the above, since the terminal reception unit 1206 has received only the server identifier of the regional server A, the transmission destination server determination unit 1207 acquires the server identifier “LocalServerA”. As a result, the transmission destination server determination unit 1207 determines to transmit various information transmitted by the terminal transmission unit 1210 to the regional server A identified by the server identifier “LocalServerA”.

  Next, it is assumed that the user A operates the portable terminal A and performs an operation for inputting a disaster situation at a certain point. At this time, for example, it is assumed that the user A selects a point from the map and then inputs a disaster situation at the point.

  In this case, first, the terminal receiving unit 1205 receives a map output instruction. And the terminal map information acquisition part 1211 acquires the map information corresponding to the terminal position information which the terminal position information acquisition part 1204 acquired from the terminal map information storage part 1203 according to the said map output instruction | indication. Then, the terminal output unit 1212 outputs the acquired map information. The situation at this time is, for example, as shown in FIG. Here, it is assumed that the user has selected the point E in FIG. Here, it is assumed that the user also selects a point (point A) indicating his / her current position.

  Next, the terminal reception unit 1205 receives a point selection instruction. Then, in response to the point selection instruction, the terminal acquisition unit 1209 acquires the point information indicating the point E and the point information indicating the point A from the map information that the terminal output unit 1212 is outputting.

  Next, the terminal reception unit 1205 receives disaster related information. Here, it is assumed that the terminal reception unit 1205 has received the disaster-related information “point E, building collapse”.

  Next, the terminal transmission unit 1210 assigns “point E, building collapse: point E: point A” in which the disaster-related information “point E, building collapse” is associated with the location information acquired above, to the regional server A. Send to. In the information, “point E” is occurrence location information. “Point A” is transmission location information.

  Next, the server receiving unit 1104 of the regional server A receives disaster-related information “point E, building collapse: point E: point A” associated with the point information and the like. Then, the server accumulation unit 1105 accumulates the disaster related information in the server storage unit 1101.

  Here, it is assumed that a user B other than the user A, a user C, and the like have also transmitted disaster-related information to the regional server A using the portable terminal B, the portable terminal C, or the like that they possess. As a result, it is assumed that the disaster storage information shown in FIG. 11 is stored in the server storage unit 1101 of the regional server A.

Are associated with transmission location information (item name: transmission location) indicating the location where each user has transmitted disaster related information and date information (item name: date) indicating the date and time when each disaster related information was transmitted. .

  Next, it is assumed that the server integration unit 1106 of the regional server A determines whether or not disaster-related information can be integrated, and determines that the integration is possible. Then, the server integration unit 1106 first compares one of the disaster related information in FIG. 11 with the other disaster related information, and determines whether or not the contents are the same. As a result, the server integration unit 1106 includes the disaster-related information of “ID = 011” to “ID = 013” and “ID = 021” to “ID = 023” of the disaster-related information in FIG. Assume that it is determined that the content is the same, that is, the target of integration.

  Next, the server integration unit 1106, for the set of disaster related information from “ID = 011” to “ID = 013”, each latitude related information is associated with longitude and latitude information as transmission location information. Of the two or more disaster related information to be integrated, it is determined that only the disaster related information transmitted from the location closest to the current position of the regional server A is left. As a result, it is assumed that the server integration unit 1106 determines that the disaster-related information with “ID = 011” is disaster-related information transmitted from a location closest to the current location of the regional server A.

  Next, for the set of disaster related information from “ID = 021” to “ID = 023”, the server integration unit 1106 associates each disaster related information with point name information as transmission location information. Since the distance to A cannot be calculated, it is determined that only the latest disaster-related information remains among the two or more disaster-related information to be integrated. As a result, it is assumed that the server integration unit 1106 determines that the disaster-related information with “ID = 023” is the latest disaster-related information.

Then, the terminal transmission unit 1210 of the portable terminal A transmits the disaster related information request instruction to the regional server A in association with the terminal identifier “Terminal A” stored in the terminal identifier storage unit 1202.

  Next, the server receiving unit 1104 of the regional server A receives the disaster related information request instruction “disaster related information: ALL” and the terminal identifier “Terminal A” associated with the disaster related information request instruction. Then, the server acquisition unit 1107 acquires all the disaster related information stored in the server storage unit 1101 in accordance with the disaster related information request instruction. Then, the server transmission unit 1108 transmits the disaster related information to the mobile terminal A identified by the terminal identifier “Terminal A”.

  Next, the terminal receiving unit 1206 of the mobile terminal A receives one or more disaster related information. The terminal accumulation unit 1208 accumulates the one or more disaster related information in the terminal storage unit 1201, and the terminal output unit 1212 outputs the one or more disaster related information. The situation at this time is, for example, as shown in FIG. In FIG. 13, type information is associated with the disaster related information, and the terminal output unit 1212 outputs the disaster related information for each type indicated by the type information. For example, the state when the one or more disaster-related information is output on the map is as shown in FIG. 14, for example. In FIG. 14, the disaster-related information is associated with position information indicating the location where the disaster occurs, and the terminal output unit 1212 outputs the disaster-related information at the position on the map indicated by the position information. The output is as follows.

  Next, it is assumed that the user A starts moving with the portable terminal A held, moves out of the range of 50 m from the regional server A, and enters the range of 50 m from the regional server B. Then, the terminal reception unit 1206 of the mobile terminal A receives the server identifier and server location information transmitted by the regional server device B. Then, the transmission destination server determination unit 1207 of the mobile terminal A performs the same processing as described above, and acquires a server identifier “LocalServerB” that identifies the regional server B.

  Next, it is assumed that the user A operates the portable terminal A and performs an operation for transmitting the disaster-related information received from the regional server A to the regional server B. Then, the terminal reception unit 1205 receives a disaster related information transmission instruction. Then, the terminal acquisition unit 1209 acquires all the disaster related information stored in the terminal storage unit 1201 in response to the disaster related information transmission instruction. Then, the terminal transmission unit 1210 transmits the acquired disaster related information to the regional server B.

  Next, the server receiving unit 1104 of the regional server B receives the disaster related information transmitted from the mobile terminal A, and the server storage unit 1105 stores the disaster related information in the server storage unit 1101.
