For example, the information communication terminal 10 and the information communication terminal 10a are mobile phones such as smartphones and mobile computers such as tablet PCs.

  Reference is made to FIG. The information communication terminal 10 according to the present embodiment has a communicable area 12 that is an area where data can be directly transmitted and received with other information communication terminals. That is, the communicable area 12 is an area where the information communication terminal 10 can directly transmit and receive data to and from other information communication terminals without going through a server. The information communication terminal 10a, which is an information communication terminal different from the information communication terminal 10, also has a communicable area 12a that is an area where data can be directly transmitted and received with other information communication terminals. In a state where the communicable area 12 and the communicable area 12a do not overlap, the information communication terminal 10 does not directly transmit / receive data to / from the information communication terminal 10a.

  Next, reference is made to FIG. The information communication terminal 10 receives information from the received data 200 automatically created by the information communication terminal 10a or a plurality of text data stored in the information communication terminal 10a when the communicable area 12 and the communicable area 12a overlap.

In addition, the information communication terminal 10 transmits the transmission data 210 automatically created by the information communication terminal 10 or a plurality of text data stored in the information communication terminal 10 when the communicable area 12 and the communicable area 12a overlap. The transmission data 210 automatically selected by the information communication terminal 10 is directly transmitted to the information communication terminal 10a.

  As a result, as shown in FIG. 2A, the transmission data 210 and the reception data 200 are exchanged directly between the information communication terminal 10 and the information communication terminal 10a. After that, when the information communication terminal 10 and the information communication terminal 10a move to different places, exchange of transmission data and reception data with another information communication terminal is executed. For example, as shown in FIG. 2B, the information communication terminal 10 transmits the transmission data 206 to the information communication terminal 10b at the timing when the communication enable area 12b of the information communication terminal 10b overlaps the communication enable area 12 of the information communication terminal 10. And the reception data 208 is received from the information communication terminal 10b. Similarly, as shown in FIG. 2C, at the timing when the communicable area 12a of the information communication terminal 10a overlaps the communicable area 12c of the information communication terminal 10c, the information communication terminal 10a transmits the transmission data 204 to the information communication terminal 10c. And the reception data 202 is received from the information communication terminal 10c.

  As described above, in the present embodiment, data transmitted from one information communication terminal to another information communication terminal is transmitted from another information communication terminal by directly transmitting and receiving data between the plurality of information communication terminals. Further, it is transmitted directly to other information communication terminals one after another. That is, the information communication terminal 10 receives the received data received from another information communication terminal or the text data created by the information communication terminal 10 at the timing when another information communication terminal enters the communicable area 12.

Then, the other information communication terminal also directly transmits the received data or text data received from the information communication terminal 10 to another information communication terminal. That is, the information communication terminal 10 according to the present embodiment functions as a data supply source, and communicates with a plurality of other information communication terminals that have entered the communicable area 12 via a communication network including a server. Send and receive data directly.

  Since the information communication terminal 10 according to the present embodiment automatically transmits and receives data at the timing when the communicable area 12 of the information communication terminal 10 and the communicable area of another information communication terminal overlap, the communication network is not connected. Even in this case, data can be exchanged with other information communication terminals. That is, a distributed network is constructed by a plurality of information communication terminals. In addition, the information communication terminal 10 can automatically acquire data related to the external situation and create the transmission data 210, and can also generate other data from the plurality of reception data 200 received from other information communication terminals and the generated transmission data 210. Since transmission data 210 to be transmitted to the information communication terminal is automatically selected, information can be transmitted / received between the information communication terminal 10 and another information communication terminal without the user operating the information communication terminal 10. .

The identifier determination unit 122 determines whether or not the second transmission terminal identifier matches the first transmission terminal identifier. Then, the identifier determining unit 122 determines that the received data is received data from the same information communication terminal when the second transmitting terminal identifier matches the first transmitting terminal identifier, and differs when the two do not match. It is determined that the received data is received from the information communication terminal. The identifier determination unit 122 supplies information indicating the determination result to the information selection unit 130.

(Information selection unit 130)
Based on the information indicating the determination result of the novelty determination unit 120 and the information indicating the determination result of the identifier determination unit 122, the information selection unit 130 is configured so that the text data stored in the data storage unit 100 or the data reception unit 110 The transmission data to be received and transmitted to the external information communication terminal is automatically selected from the reception data stored in the data storage unit 100. Specifically, the information selecting unit 130 receives information indicating that the received data is new received data from the novelty determining unit 120, or displays information indicating that the received data is old received data from the novelty determining unit. 120, when receiving from the identifier determination unit 122 information indicating that the received data is received from a different information communication terminal, the reception frequency of the received data, or a predetermined priority of text data or received data The transmission data is selected based on.

  Specifically, the information selection unit 130 can select the reception data having the maximum reception frequency as transmission data. Here, the reception frequency is a number that matches the number of different information communication terminals when the same reception data is received from each of the different information communication terminals. For example, when the body data, creation terminal identifier, and date / time data included in each of n pieces (where n is a positive integer of 2 or more) are the same, that is, n pieces of received data are the same. If the second transmitting terminal identifier corresponding to each received data is different, the information selecting unit 130 measures that the received data has been received n times. Then, the information selection unit 130 determines that the reception frequency of the received data is “n”.

  The information selection unit 130 associates the reception frequency with each of the plurality of reception data received by the data reception unit 110. Then, the information selection unit 130 compares the reception frequencies associated with each of a plurality of different reception data, and selects the reception data having the maximum reception frequency as transmission data. Note that the information selection unit 130 can also include a reception frequency database in which reception data is associated with reception frequency of the reception data.

That is, the information selection unit 130 can compare the reception frequencies associated with each of the plurality of reception data, and can select the reception data with the minimum reception frequency as transmission data. Here, when there are a plurality of pieces of reception data having the maximum or minimum reception frequency, the information selection unit 130 selects transmission data based on the date / time data included in the reception data. For example, the information selection unit 130 can select, as transmission data, reception data indicating the date and time when the creation date and time of the body data indicated by the date and time data is the latest.

  Furthermore, the information selection unit 130 can select transmission data at random regardless of whether the reception frequency is maximum or minimum. A selection method in the case where the information selection unit 130 selects transmission data using the reception frequency can be determined in consideration of, for example, population density or population distribution in an area where the information communication terminal 10 is used.

  The information selection unit 130 can also select transmission data according to the priority level of the content indicated by the body data included in the received data or text data. For example, the priority of received data or text data having body data including information corresponding to disaster-related contents is set higher than the priority of received data or text data having body data including information corresponding to other contents .

  As an example, the information selection unit 130 includes a priority database in which one word is associated with a priority indicating the priority of the one word. First, the information selection unit 130 compares the words in the body data included in the received data or text data with the words stored in the priority database. Next, the information selection unit 130 associates information indicating the priority order associated with the words stored in the priority database with each of the plurality of received data or the plurality of text data. And the information selection part 130 selects the reception data or text data matched with the information which shows a higher priority as transmission data. The information selection unit 130 supplies the selected transmission data to the data transmission unit 112.

  In short, in the present invention, the content of the data is confirmed and the same information is not propagated to other information terminals, and information obtained from a plurality of information terminals is important information even if it is the same information. Judgment criteria regarding the two-stage information transmission that is determined to be propagated. By this standard, instead of inadvertently propagating information and flooding it, just as information is transmitted according to the number of times of propagation, only new information is propagated and information that is estimated to be highly important. By selecting and propagating, the above-mentioned desired purpose is achieved.

(Data transmission unit 112)
The data transmission unit 112 transmits the transmission data selected by the information selection unit 130 to the external information communication terminal at the timing when the external information communication terminal enters the communicable area 12 of the information communication terminal 10. Here, the timing at which the data reception unit 110 receives the reception data from the external information communication terminal and the timing at which the data transmission unit 112 transmits the transmission data may be different timings.

Then, the image analysis unit supplies the information conversion unit 146 with a condition identifier that identifies one condition that matches the analysis result among a plurality of predetermined conditions. If the information received from the information acquisition unit 142 does not match any of a plurality of predetermined conditions, the determination unit 144 waits until information is acquired from the information acquisition unit 142 next time.

  For example, the information conversion unit 146 includes a conversion database that stores text data indicating the content of information corresponding to the condition identifier in association with the condition identifier. For example, the conversion database stores text data indicating that a fire has occurred in association with a condition identifier corresponding to temperature information indicating a predetermined temperature or higher. Then, the information conversion unit 146 acquires text data corresponding to the condition identifier received from the determination unit 144 from the conversion database. The information conversion unit 146 creates text data including the acquired text data as body data, and stores the created text data in the data storage unit 100.

  When the information conversion unit 146 stores the text data in the data storage unit 100, the text data includes a creation terminal identifier for identifying the information communication terminal 10 and date / time data indicating the date / time when the body data was acquired or created. Corresponding by the information conversion unit 146. Thereby, the information conversion unit 146 converts information representing an external situation into text data. The text data becomes transmission data when selected by the information selection unit 130.

On the other hand, when the received data is not new, the novelty determining unit 120 supplies information indicating that the received data is not new to the identifier determining unit 122 (S30: N).

  When receiving the information that the received data is not new, the identifier determining unit 122 determines whether the second transmitting terminal identifier included in the received data is a new second transmitting terminal identifier (40). When the second transmitting terminal identifier included in the received data is a new second transmitting terminal identifier, the identifier determining unit 122 transmits information received by the received information that has already been received by the information communication terminal 10. It is determined that the information is received from an information communication terminal different from the terminal (S40: Y). Then, the identifier determination unit 122 supplies the determination result to the information selection unit 130.

  On the other hand, when the second transmitting terminal identifier included in the received data is not a new second transmitting terminal identifier, the identifier determining unit 122 transmits the received data that the information communication terminal 10 has already received. It is determined that the information is transmitted from the same information communication terminal as the information communication terminal (S40: N). In response to this determination by the identifier determining unit 122, the data receiving unit 110 and / or the data transmitting unit 112 continues to monitor whether another information communication terminal has entered the communicable area 12.

  The information selection unit 130 executes a process of selecting transmission data to be transmitted to another information communication terminal based on the determination result of the novelty determination unit 120 and the determination result of the identifier determination unit 122 (S50). Then, the information selection unit 130 supplies the selected transmission data to the data transmission unit 112. Subsequently, the data transmission unit 112 transmits the transmission data selected by the information selection unit 130 to the other information communication terminal when another information communication terminal enters the communicable area 12. The data transmitting unit 112 can also include a buffer that temporarily stores transmission data until another information communication terminal enters the communicable area 12.

It is assumed that received data “Y” is received from the information communication terminal 10d, the information communication terminal 10f, and the information communication terminal 10g. In this case, since both the plurality of received data “X” and the plurality of received data “Y” are transmitted from different information communication terminals, the information selecting unit 130 receives the received data based on the determination result of the identifier determining unit 122. The reception frequency of “X” is determined as “4”, and the reception frequency of reception data “Y” is determined as “3”. Then, the information selection unit 130 selects reception data “X” having the highest reception frequency as transmission data.

  Subsequently, the data transmission unit 112 transmits the reception data “X” selected by the information selection unit 130 as transmission data 212 to another information communication terminal 10 h that has entered the communicable area 12. In this case, the transmission data 212 includes text data included in the reception data “X”, a creation terminal identifier of the information communication terminal that created the text data, and date / time data indicating the date and time when the text data was created. And the transmission terminal identifier of the information communication terminal 10 as the second transmission terminal identifier.
