Description

The present invention relates to an information communication device and an information communication control program that enable the use of information communication services within a specific area.

In recent years, natural disasters such as earthquakes, tsunamis, typhoons, and heavy rain have been increasing worldwide. When a disaster occurs, people in the disaster area collect disaster situation and evacuation information in order to ensure their own safety, confirm the safety of their family, friends and acquaintances, and protect their property, and then assess the situation based on the collected information. Find out and take action.

For example, immediately after a disaster, people receive evacuation information sent from local governments via disaster prevention radio, etc., and evacuate to designated evacuation shelters.

In addition, in disaster response organizations such as local governments, police, fire departments, medical institutions, and the Self-Defense Forces, teams rush to disaster sites, etc., and communicate with team members to understand the damage situation and carry out rescue and recovery operations. Promote disaster response in an organized manner by sharing disaster damage information within and outside the organization. As a result, in and around the disaster area, demand for communication services such as telephones and the Internet increases sharply, creating congestion that makes it difficult to connect to networks.

By the way, in order to cope with the congestion state that makes communication difficult to connect during such disasters, Patent Document 1 provides an access control function to the base station to which the mobile phone terminal is connected, and By controlling access so that only mobile phone terminals (in other words, in the base station coverage area) can access the information sharing server on the network to provide and collect (browse) information, the congestion problem that occurs in disaster-stricken areas can be resolved. A disaster area information sharing system has been proposed.

Furthermore, Patent Document 2 proposes an information distributed management system that makes it possible to share the minimum amount of information even if the communication line is disconnected or the distribution server at the center malfunctions. There is.

The system disclosed in Patent Document 2 is composed of a plurality of tourism/disaster prevention Wi-Fi (Wireless Fidelity) stations and a tourism/disaster prevention Wi-Fi station center, and each tourism/disaster prevention Wi-Fi station connects to a local intranet line or points. It is configured to be connected to the tourism/disaster prevention Wi-Fi station center using a wireless access device.

Each tourism/disaster prevention Wi-Fi station has a Wi-Fi access point, camera, sensor, and information management device fixed to a pole, and the information acquired by the camera and sensor is organized and processed by the information management device. The data is then sent to the distribution server at the center via the network.

Users use the Wi-Fi function from information communication devices such as smartphones to access the information management device or the distribution server of the center to access the necessary information, obtain information (collection), upload information (share), etc. ) to use the system. If a failure occurs in the network connecting the information management device and the distribution server, the information management device can also temporarily take over information access and uploading from users. This allows users in the event of a disaster to access the system via a Wi-Fi device using their information and communications equipment to send posted information and safety confirmation information, as well as receive disaster information and camera video information.

By the way, in the event of a large-scale disaster, infrastructure such as electricity, gas, water, and communications may be damaged and become unusable. Even in information and communication services such as telephones and the Internet, communication disruptions can occur during disasters, such as collapsed utility poles, cut cables, damage to communication buildings, power outages at base stations, etc., making it impossible to use telephones or the Internet.

If communications are disrupted, in addition to telephone services, SNS (Social Networking Services), e-commerce, search services, video distribution services, etc. that are widely used on the Internet may become completely unavailable or extremely difficult to use. fall into a situation where Moreover, it is difficult to accurately predict in advance when and where such disasters and damage will occur.

Here, at the time of a large-scale disaster, the problem that it becomes difficult to collect and share disaster information due to communication congestion in a disaster-stricken area can be alleviated by Patent Document 1.

However, the method of Patent Document 1 relies on the existing communication network to access the information sharing server, and it becomes unusable or difficult to use if communication is disrupted during a disaster (damage to the communication network, network disconnection, etc.). There is an issue of becoming.

On the other hand, the method of Patent Document 2 allows the local intranet line and wireless access line that connect the tourist/disaster prevention Wi-Fi station and the center to be unique even in an environment where communication services including Internet connection provided by a communication company are disrupted. If it is, you can make it work.

In addition, even if the regional intranet line or wireless access line becomes unavailable due to a disaster, the information management equipment installed at each station can temporarily replace the information distribution server located at the center, allowing users to access information. It makes it possible to access the system using communication devices and collect and share disaster information.

However, the system of Patent Document 2 is based on the premise that it is installed in advance at tourist destination facilities, evacuation centers, etc., and it is necessary to prevent disasters, communication disruptions, or sudden increases in communication demand in places where these systems are not installed. It is difficult to deal with the occurrence of congestion due to

Furthermore, even if the information management equipment installed at each station replaces the information distribution server located at the center, in the event of a prolonged communication outage, the users who can handle each information management equipment will The problem is that the Wi-Fi stations are limited to the areas where they are installed, making it difficult to collect, share, and communicate information among users connected to multiple sightseeing and disaster prevention Wi-Fi stations.

On the other hand, in the event of a large-scale disaster, local governments and the like widely disseminate evacuation information using disaster prevention radio and loudspeakers. At that time, it was recognized in cases such as the Great East Japan Earthquake that the sound could be difficult to hear due to factors such as the weather at the time of a disaster, the location of loudspeakers, and the location of residents, making it impossible to reliably convey information.

In addition, in the event of a disaster, not only local government employees but also people from various disaster support organizations such as medical institutions, the Self-Defense Forces, police, and fire departments come and go to the disaster response headquarters set up in local governments, etc. Information that requires careful handling such as information that requires careful management is also shared.

FIG. 8 shows information communication devices 100.1 to 100.3 of the second embodiment and communication terminals 10.1 to 10.1 held by users. FIG. 1 is a conceptual diagram showing a system configured with

Note that although three information communication devices 100.1 to 100.3 are illustrated in FIG. 8, the number of information communication devices is not limited to this.

Referring to FIG. 8, similarly to Embodiment 1, information communication device 100.1 provides communication terminals 10.1 to 10. n operates as a server and performs server-client communication via an access point 2400 via a wireless LAN.

On the other hand, it is assumed that the administrator and the like take advantage of the portability of the information communication device 100.1 to visit other evacuation shelters together with the information communication device 100.1.

At this time, it is assumed that the information communication device 100.2 and the information communication device 100.3 are installed in the other evacuation shelters, respectively. It is assumed that the information communication device 100.2 and the information communication device 100.3 have the same configuration as the information communication device 100.1.

As will be described later, it is assumed that the information communication device 100.1 operates as a client device for server-client communication via the network communication unit 2410 during this patrol period. The operation as a server device and the operation as a client device are set by the administrator in advance by predetermined operations before the patrol.

While the information communication device 100.1 is patrolling, the information communication device 100.1 searches for the presence of communicable devices, and when the information communication device 100.1 enters the communicable area of the information communication device 100.2 or 100.3, the server - Becomes client communication mode, compares information held by each other, and synchronizes each other's information. As a result, after the information communication device 100.1 returns from patrolling to the original installation location, for example, the original evacuation center, the information communication device 100.1 stores the information uploaded at the original installation location. In addition, information uploaded at other installation locations (such as evacuation centers) is also retained.

The information communication device 100.1 executes data synchronization processing with the communication partner while establishing a communication path for bidirectional communication with the communication partner. Note that data transmitted and received with the communication partner during data synchronization processing may be encrypted with a predetermined key or a predetermined password may be set. In addition, when encrypting connection information or synchronized data or setting a password with the communication partner, the nonvolatile storage device 2080 stores in advance key information and password information used for the encryption. It is also possible to have a configuration in which

9 and 10 are sequence diagrams for explaining the operations of information communication devices 100.1 to 100.3.

Referring to FIG. 9, in the patrol mode, information communication device 100.1 exists within an area where other information communication devices can communicate using the client function (within a range where Wi-Fi clients can receive radio waves). A search is made to see if there is an error (S200).

When detecting that information communication device 100.2 exists within a communicable area, information communication device 100.1 transmits an authentication request to information communication device 100.2 (S202), and When the information communication device 100.2 is authenticated as a communicable device by the authentication process of 100.2 (S204), the information communication device 100.2 transmits an access permission notification to the information communication device 100.1 (S206).

After the access is granted, the information communication device 100.1 and the information communication device 100.2 each perform internal inquiry processing for their own retained data information (S208a, S208b), and exchange information on the inquiry results. (S210), compares the held information of own held data and the held data of the other side (S212a, S212b), and extracts difference information of the held data, respectively (S214a, S214b).

Subsequently, the information communication device 100.1 and the information communication device 100.2 execute data synchronization processing for the data held by each other based on the difference information (S216).

When the synchronization process is completed, the information communication device 100.1 uses the client function again to search whether there is another information communication device that has not yet undergone data synchronization within the communicable area (S218).

When detecting that information communication device 100.3 exists within the communicable area, information communication device 100.1 communicates with each other by the same process as that executed for information communication device 100.2. Data synchronization processing is executed for the data held by (S220 to S234).

Referring to FIG. 10, when information communication device 100.1 returns from patrolling to its original installation location (for example, the original evacuation center), for example, communication terminal 10. The normal user of i accesses the server device 2010 (S236) and transmits data through the processing of the user interface unit 2044 of the server device 2010 (S238), so that the terminal 10. The menu screen of the top page 31 is displayed on the display unit 118 of i (S240).

When the user selects public information (S242), the information public information unit 2042 and user interface unit 2044 transition to public information mode (S244), and the public information screen is displayed on the user terminal 10. i is displayed on the display section 118 (S246).

Also, the user terminal 10. In response to the instruction to move to the top page from i (S248), data is transmitted through the processing of the user interface unit 2044 of the server device 2010 (S250), and the terminal 10. The menu screen of the top page 31 is displayed on the display unit 118 of i (S252).

Next, the communication terminal 10. If information sharing is selected from the communication terminal 10. The information sharing screen 33 is displayed on the display unit 118 of i (S258).

A user uses a communication terminal 10. When the shared information is transmitted by operating the operating unit of i (S260), the information storage/storage processing unit 2046 of the server device 2010 stores the uploaded data in the SSD 2080 as shared information (S262).

At this time as well, the communication terminal 10. The shared information from i is stored in the SSD 2080 in association with information for identifying and specifying the uploading user and sharing approval information.

Since the subsequent operation is the same as that described in Embodiment 1, the description will not be repeated.

In this way, by using the data synchronization function between adjacent systems of this embodiment, it is possible to more effectively utilize the portable configuration of the information communication device 100.1.

In addition to the above-described form, it is also possible to perform information synchronization processing at a plurality of installation locations, for example, as follows.

For example, assume that information communication devices are deployed at multiple evacuation centers during a disaster and are used for information exchange and sharing within each evacuation center. Here, it is assumed that an information communication device (hereinafter referred to as a "patrolling information and communication device") different from the information and communication devices already deployed is used, and this patrolling information and communication device is to be used as a vehicle to patrol evacuation centers. . When this patrol information communication device approaches the information communication device installed at each evacuation center, a synchronization function is activated between both systems to adjust data differences and perform a synchronization operation.

When this traveling information communication device makes a round of evacuation shelters, the information communication devices at each evacuation center will hold almost the same data. This shows that multiple shelters can be made to operate as one area. In other words, it can be seen that the service provision area can be expanded to multiple evacuation centers.

Although the synchronization function in this embodiment is assumed to be performed between adjacent portable information communication systems, the use of the synchronization function is not limited to this. For example, information communication devices can be connected to each other via the Internet. A similar synchronization function can also be used in cases where In this case, when communication is restored after communication interruption, it becomes possible for a plurality of information communication devices to automatically share their isolated service usage status with other systems.

Further, in the above description, the data synchronization function for two portable information communication devices has been described, but the number of systems to be synchronized is not limited to two, but may be three or more.
[Embodiment 3]
FIG. 11 is a block diagram for explaining the configuration of information communication device 100.1' according to the third embodiment.

The configuration in FIG. 11 is compared with the configuration in FIG. 3, and the same parts are given the same reference numerals.

In addition to the configuration shown in FIG. 3, the information communication device 100.1' includes a voice synthesis section 2500 that converts a signal given by control from the CPU 2040 into voice, and a speaker that sends out the signal from the voice synthesis section 2500 as voice. 500.

FIG. 12 is a sequence diagram for explaining the operation of the information communication device 100.1'.

Referring to FIG. 12, CPU 2040 of information communication device 100.1' generates an access control signal based on access control information stored in advance in nonvolatile storage device 2080 (S300). The access control information may be, for example, a character string randomly generated from a predetermined range of characters, numbers, and symbols as binary information.

Next, the audio synthesis unit 2500 converts the access control signal into an audio signal by tone modulation, intensity modulation, etc. according to a predetermined method (S302), and this audio signal is output from the speaker 500 into the space (S304). .

Here, the frequency of the sound used as a carrier may be within the operating range of the speaker 500 of the information communication device 100.1' and the audio input section 114 of the communication terminal 10.1.

Alternatively, the information may be transmitted superimposed with human-recognizable audio such as normal broadcasting. In this case, a low audible frequency band or a frequency band that can hardly be heard by people in a wide area can be used as the access signal transmission carrier.

It is assumed that the access control signal transmitted from the speaker 500 can be received by a plurality of communication terminals within a sound range. FIG. 12 exemplarily shows the operation of communication terminal 10.2.

The communication terminal 10.2 receives the access control signal as a voice signal, extracts the access control signal from the received sound (S306), and generates combined information by adding this access control signal to the normal ID and password. Then, using this as authentication information (S308), an authentication request is transmitted to the information communication device 100.1' via the wireless LAN (S310).

The information communication device 100.1' receives the authentication request (S312), and presents the received signal with the information necessary for normal access such as ID and password, as well as the access control information originally sent from the system side. The authentication process is executed by checking whether the authentication has been performed (S314).

If the access control information is correctly presented, the information communication device 100.1' permits access to the service and notifies the user terminal of this fact (S316). After receiving the notification, the terminal device 10.2 can access the top page and receive services such as information sharing (S318 to S328).

According to the method described above, only a terminal device that can receive the wireless LAN signal of the information communication device 100.1' and can receive the access control signal by sound can access the information communication device 100.1'.

As a result, for example, in the event of a large-scale disaster, when broadcasting disaster information in the form of audio to a local area using a method such as disaster prevention radio, the access control signal can be superimposed on the disaster prevention radio broadcast using the signals from the voice synthesizer 2500 and the speaker 500. When the broadcast is amplified, users who can hear the broadcast and are within the wireless LAN communication area of the information communication device 100.1' are automatically accessed to a page of information related to the broadcast content through access control using an access control signal. By controlling in this way, it becomes possible to reliably disseminate disaster information via the portable information communication system even in situations where it is difficult to hear voices over disaster prevention radio.

On the other hand, if you want to use the information communication device 100.1' to disseminate or exchange information only to people in a limited place, for example, install the information communication device 100.1' in a room. However, the access control signal can be broadcast through a speaker or the like as audio that can only be received within the room, and necessary information can be exchanged by accessing the system via wireless LAN. Such a limited location can be assumed to be a disaster response headquarters set up at a prefectural or city hall in the event of a large-scale disaster, and in this use case, the area around the location where the disaster response headquarters is located, such as an adjacent building, can be assumed. This prevents information from being stolen in areas where radio waves can reach.

In the above description, the access control signal is transmitted using an audio signal, but the present invention is not limited to such a configuration.

For example, since the communication terminal 10.1 is normally equipped with a camera section 128, for example, instead of providing the voice synthesis section 2500 and the speaker 500 in the information communication device 100.1', an optical It is also possible to provide a signal generation unit and a light that can be blinked under signal control, and to perform the transmission of the access control signal using an optical signal.

Furthermore, when using an optical signal, in addition to the configuration in which the access control signal is transmitted by such an optical signal generation unit and a light, for example, the outer surface of the casing or the casing of the information communication device 100.1' is used. When the body is opened, a medium that displays a two-dimensional code is attached to the inside of the lid, etc., and this is photographed by the camera unit 128 of the communication terminal 10.1, thereby transmitting the access control signal. Good too. When attaching a medium that displays a two-dimensional code to the outer surface of the casing, normally the medium is attached face down so that the two-dimensional code cannot be seen, and then it can be attached face up when necessary. It may be configured as follows.

The information communication device or the information communication control program of Embodiments 1 to 3 can easily construct a local information communication environment anytime and anywhere in a communication disruption situation that may occur during a large-scale disaster that is difficult to predict in advance. be able to.

Furthermore, the information communication devices of Embodiments 1 to 3 can be used not only in times of large-scale disasters, but also in places where there is a temporary demand for information communication, such as various events and construction projects, and where there is a sufficient Internet connection environment. It is also possible to use it in developing countries where it is not yet available.
