Description

Technical Field

[0001] The present disclosure relates to a household radio, a disaster prevention wireless communication system, a disaster prevention wireless communication method, and a program.

Background Art

[0002] Currently, as a disaster prevention wireless system that is generally in practical use, there are voice broadcasts by loudspeakers and household receivers using disaster prevention administrative radio. General residents make decisions in an emergency based on broadcasts from disaster prevention administrative radio. When it is expected that the residential house will be damaged, they evacuate to designated evacuation sites such as community centers. Local governments that transmit evacuation information using disaster prevention administrative radio are required to grasp whether evacuees who need support in evacuation actions have confirmed the evacuation information and evacuated to the designated evacuation sites.

[0003] For example, Patent Document 1 below discloses a crime prevention and disaster prevention information system that can confirm the safety of people taking shelter in an evacuation site such as a community center.

Summary of the Invention

Problems to be Solved by the Invention

[0005] However, in the crime prevention and disaster prevention information system described in Patent Document 1, safety information is entered solely through safety information input devices installed at evacuation centers. Therefore, it was not possible to track the progress of evacuation for those requiring assistance or to determine if they were staying at home for any reason. Furthermore, the means of transmitting disaster prevention information implemented by local governments are one-way, such as broadcasts using loudspeakers or transmission of evacuation information to individual receivers, making it difficult to easily confirm the safety of residents in dangerous areas when a disaster occurs. As a result, local government officials had to visit homes individually as needed to check on the status of those requiring assistance.

[0006] In light of the above issues, this disclosure aims to provide individual wireless devices, a disaster prevention wireless communication system, a disaster prevention wireless communication method, and a program that enable administrators such as local governments to easily grasp the evacuation behavior of persons requiring assistance during evacuation. [Means for solving the problem]

[0007] To solve the above-mentioned problems and achieve the objective, the household radio device relating to this disclosure is a household radio device that communicates with a mobile terminal and a communication device, comprising: an emergency information receiving unit that receives emergency information from a radio station; a location information acquisition unit that acquires the location information of the device itself; a first communication unit that connects with the mobile terminal and the communication device and transmits and receives information; a mobile terminal information acquisition unit that acquires terminal-specific information, time information, location information, and movement information of the mobile terminal as mobile terminal information from the information received by the first communication unit; and a first information unit that determines whether the mobile terminal is moving with the device based on the location information of the device itself and the location information of the mobile terminal, and generates evacuation terminal information from the mobile terminal information of the mobile terminal that is determined to be moving with the device. The system comprises an information generation unit, a first storage unit that stores mobile terminal registration information which is information of a mobile terminal authorized to connect to the system, the system's location information, the mobile terminal information acquired by the mobile terminal information acquisition unit, and evacuation terminal information generated by the first information generation unit, a first beacon transmission unit that transmits a beacon signal, and a first operation control unit that controls the system's operation. When the emergency information receiving unit receives emergency information, the first operation control unit controls the first communication unit to transmit the mobile terminal registration information stored in the first storage unit, the system's location information, the mobile terminal information, and the evacuation terminal information to the communication device, and controls the first beacon transmission unit to transmit the evacuation terminal information as a beacon signal.

[0008] To solve the above-mentioned problems and achieve the objective, the disaster prevention radio communication system relating to this disclosure is a disaster prevention radio system comprising a communication device and a home radio that receives emergency information from a radio station and communicates with a mobile terminal and the communication device, wherein the home radio comprises an emergency information receiving unit that receives emergency information from a radio station, a location information acquisition unit that acquires its own location information, a first communication unit that connects to the mobile terminal and the communication device and transmits and receives information, a mobile terminal information acquisition unit that acquires terminal-specific information, time information, location information and movement information of the mobile terminal as mobile terminal information from the information received by the first communication unit, a first information generation unit that determines whether the mobile terminal is moving with the device based on the location information of the device and the location information of the mobile terminal, and generates evacuation terminal information from the information of the mobile terminal that is determined to be moving with the device, mobile terminal registration information, location information of the device, the mobile terminal information acquired by the mobile terminal information acquisition unit, and the first information generation unit The communication device comprises a first storage unit that stores the generated evacuation terminal information, a first beacon transmitting unit that transmits a beacon signal, and a first operation control unit that controls the operation of the individual wireless device.

[0013] Hereinafter, embodiments of the present disclosure will be described in detail based on the drawings. Note that the present disclosure is not limited by the embodiments described below.

[0014] (First Embodiment) (Configuration of Disaster Prevention Wireless Communication System) First, the configuration of the disaster prevention wireless communication system according to the first embodiment of the present disclosure will be described with reference to FIG. 1. FIG. 1 is a diagram showing the configuration of the disaster prevention wireless communication system according to the first embodiment of the present disclosure and the relationship between the disaster prevention wireless communication system according to the first embodiment and other configurations. As shown in FIG. 1, the disaster prevention wireless communication system 1 according to the first embodiment of the present disclosure includes a door-to-door radio 100 and a communication device 200. Further, as shown in FIG. 1, the door-to-door radios 100 constituting the disaster prevention wireless communication system 1 are communicably connected to each other via radio waves RW with mobile terminals 300 (300A, 300B, 300C). Further, as shown in FIG. 1, the door-to-door radio 100 receives emergency information DRW transmitted from the radio station 400. Hereinafter, after briefly explaining these configurations, an outline of the processing of the disaster prevention wireless communication system 1 according to the first embodiment will be described. Here, the disaster prevention wireless communication system 1 is configured to receive emergency information DRW transmitted from the radio station 400, but it may be a radio station that transmits emergency information. The emergency information transmitted from the radio station may be special warnings, warnings, or advisories regarding meteorology such as rain, floods, and high tides, landslide advisories, landslide disaster warning information, emergency earthquake quick reports, tsunami warnings, flood information for rivers, etc., volcanic eruption warnings, disaster information, special warnings, warning alerts against wild animals and suspicious persons, emergency information, etc. Any disaster prevention wireless communication system 1 that receives such emergency information and performs processing based on the received information may be used.

[0015] The household radio 100 is a radio arranged for each household in the residences within the jurisdiction of the local government. When an evacuation instruction is issued by the local government, the household radio 100 can be carried out by those who need support for evacuation actions, and guides those who need support for evacuation actions to the evacuation site. When guiding evacuation by the household radio 100, the household radio 100 moves while transmitting a beacon signal toward the surroundings, and notifies nearby neighboring residents and administrative personnel passing by that those who need support for evacuation actions are evacuating.

[0016] The household radio 100 may be, for example, a digital mobile disaster prevention administrative radio capable of receiving radio waves in the 260 MHz band. As a modulation method used for the digital mobile disaster prevention administrative radio, a π / 4 shift QPSK (Quadraphase Shift Keying: 4-phase shift modulation) method or a 4-value FSK (Frequency Shift Keying: frequency shift modulation) method may be used. Also, the right to use the transmission path may be allocated by 4-slot TDMA (Time Division multiple access) to enable multiple access. Thereby, direct calling of individual terminals, realization of data communication such as multi-channeling and image transfer becomes possible. The household radio 100 receives disaster prevention radio waves from, for example, the radio station 400.

[0017] The communication device 200 is a base station or a simple base station that manages the household radio 100. The communication device 200 receives the information transmitted from the household radio 100 and performs processing based on the received information.

[0018] The mobile terminal 300 is a communication terminal that can be carried by a person requiring assistance during evacuation. The mobile terminal 300 may acquire location information (latitude and longitude) measured based on radio waves received by a GPS (Global Positioning System) receiver or GNSS (Global Navigation Satellite System) receiver equipped in the mobile terminal 300. The mobile terminal 300 is a portable communication terminal that has the function of measuring location information and the function of communicating with the individual wireless radio 100 using Wi-Fi® communication, i.e., wireless LAN (Local Area Network) communication. For example, it may be a smartphone, tablet terminal, notebook PC, mobile phone, PDA (Personal Digital Assistant), or other communication terminal.

[0019] Radio station 400 is a base station that transmits disaster prevention radio waves (60MHz band and 260MHz band radio waves). Radio station 400 is installed, for example, at a municipal office and transmits various emergency information to residents using disaster prevention radio waves to individual radio units 100 when a disaster occurs in that municipality. Radio station 400 is equipped with, for example, an antenna and a transmitter to transmit emergency information as disaster prevention radio waves.

[0020] Next, an overview of the processing of the disaster prevention radio communication system 1 will be explained. First, the individual radio 100 receives emergency information from the radio station 400. Once the individual radio 100 receives emergency information, it obtains location information at predetermined time intervals from the mobile terminals 300 that are registered to connect to the individual radio 100 and are evacuating with the individual radio 100, and compares this with the location information of the individual radio 100 to determine whether or not the mobile terminal 300 is moving within a predetermined range from the location of the individual radio 100. When the individual radio 100 is taken away, it continues to transmit information stored in the individual radio 100, including the unique information of the mobile terminal 300 that is moving with the individual radio 100 and evacuating, to the communication device 200 until communication with the communication device 200 is interrupted. The communication device 200 can connect to and communicate with the individual wireless radio 100. If the individual wireless radio 100 is taken out due to an evacuation order, the communication device 200 transmits a beacon signal towards the area around the house where it is installed, indicating that the household that took out the individual wireless radio 100 has evacuated, informing nearby residents and government officials passing by. The beacon signal transmitted from the communication device 200 includes unique information of a mobile terminal 300 that did not evacuate with the individual wireless radio 100 and may have been left behind, identified based on the information stored in the individual wireless radio 100.

[0021] (Configuration of individual home radio systems) Next, the configuration of the individual wireless radio 100 will be described using Figure 2. Figure 2 is a diagram showing an example of the configuration of an individual wireless radio according to the first embodiment of this disclosure. As shown in Figure 2, the individual wireless radio 100 comprises a first communication unit 110, a first storage unit 120, and a first control unit 130. These configurations will be described in order below.

[0022] (Regarding the First Communications Department) The first communication unit 110 connects the inside and outside of the individual wireless radio 100 so that they can communicate with each other, and transmits and receives information between the inside and outside of the individual wireless radio 100. The first communication unit 110 may be implemented by, for example, a NIC (Network Interface Card), a wireless LAN (Local Area Network) card, a Bluetooth® module, a WiFi® module, an antenna, etc. Here, the first communication unit 110 communicates with the second communication unit 210 of the communication device 200 described later, and transmits and receives information to each other. The process of transmitting information stored in the first storage unit 120 to the communication device 200 may be continued until communication between the individual wireless radio 100 and the communication device 200 is interrupted. For example, the content to be transmitted until communication is interrupted may include information about the individual wireless radio 100 stored in the individual wireless radio information storage unit 121 described later, information about the mobile terminal 300 stored in the mobile terminal information storage unit 122, and information about the evacuation terminal stored in the evacuation terminal information storage unit 123. It is preferable to continue communication between the individual wireless transceiver 100 and the communication device 200 so that the contents stored in the first storage unit 120 of the individual wireless transceiver 100 and the contents stored in the second storage unit 220 of the communication device 200 are synchronized as much as possible until communication between the individual wireless transceiver 100 and the communication device 200 is interrupted.

[0023] As shown in Figure 2, the first communication unit 110 includes an emergency information receiving unit 111 and a first beacon transmitting unit 112.

[0024] The emergency information receiving unit 111 receives emergency information from the radio station 400. That is, the emergency information receiving unit 111 receives emergency information transmitted from the radio station 400 as disaster prevention radio waves. The emergency information receiving unit 111 is equipped with an antenna that can receive radio waves in the 60MHz band and 260MHz band that transmit emergency information, and may receive emergency information using the antenna. When the emergency information receiving unit 111 receives emergency information from the radio station 400, it transmits reception notification information to the communication device 200 to notify that it has received emergency information.

[0025] The first beacon transmitter 112 transmits a beacon signal containing evacuation terminal information. The first beacon transmitter 112 transmits a beacon signal based on a command from the first operation control unit 135, which will be described later. By receiving the beacon signal using a terminal that can receive the beacon signal transmitted by the individual radio 100, administrative officials can confirm the evacuation terminal information moving with the individual radio 100, and grasp the status of persons requiring evacuation assistance who have received emergency information. The first communication unit 110 may also continue the process of transmitting the evacuation terminal information stored in the evacuation terminal information storage unit 123 of the first storage unit 120 to the communication device 200 until communication between the individual radio 100 and the communication device 200 is interrupted. In this case, the first beacon transmitter 112 may include the evacuation terminal information in the beacon signal when transmitting it.

[0026] (Regarding the first memory unit) The first storage unit 120 is a storage device that stores various types of information. The first storage unit 120 comprises a main memory and an auxiliary storage device. The main memory may be implemented using semiconductor memory elements such as RAM (Random Access Memory), ROM (Read Only Memory), or flash memory. The auxiliary storage device may be implemented using a hard disk, SSD (Solid State Drive), or optical disc, for example.

[0027] As shown in Figure 2, the first storage unit 120 includes a household radio information storage unit 121, a mobile terminal information storage unit 122, and an evacuation terminal information storage unit 123. The first storage unit 120 stores the mobile terminal registration information described later, the location information of the household radio 100 which is the unit itself, the mobile terminal information acquired by the mobile terminal information acquisition unit 132, and the evacuation terminal information generated by the first information generation unit 133. These configurations will be explained in detail below.

[0028] (Regarding the information storage unit of individual wireless transceivers) The individual radio information storage unit 121 stores information related to the individual radio 100. The information stored in the individual radio information storage unit 121 will be explained using Figure 3. Figure 3 is a diagram showing an example of the information stored in the individual radio information storage unit according to this disclosure.

[0029] In the example shown in Figure 3, the individual wireless device information storage unit 121 stores information related to the following items in association: "terminal-specific information," "time information," "location information," and "movement information."

[0030] "Terminal-specific information" is an identifier that identifies the individual radio 100, and is represented, for example, by a string of characters or a number. "Time information" is information indicating the time when the individual radio 100 received emergency information from the radio station 400. "Location information" is information indicating the location of the individual radio 100, i.e., its latitude and longitude. "Motion information" is information indicating the movement of the individual radio 100, i.e., its speed.

[0031] In other words, Figure 3 shows that the individual radio 100, indicated by the terminal-specific information "ID-A", receives emergency information from the radio station 400 at the time indicated by the time information "Time Information A", and that the location of the individual radio 100 at that time is stored as location information "Location Information A", and the movement of the individual radio 100 is stored as movement information "Movement Information A".

[0032] Furthermore, the individual radio information storage unit 121 is not limited to information relating to the items "terminal-specific information," "time information," "location information," and "movement information," but may store any other information relating to the individual radio 100.

[0033] (Regarding the mobile device information storage unit) The mobile terminal information storage unit 122 stores information related to the mobile terminal 300. The information stored in the mobile terminal information storage unit 122 will be explained using Figure 4. Figure 4 is a diagram showing an example of the information stored in the mobile terminal information storage unit according to this disclosure.

[0034] In the example shown in Figure 4, the mobile terminal information storage unit 122 stores information related to the following items in association: "terminal-specific information," "time information," "location information," and "movement information."

[0035] "Terminal-specific information" is an identifier that identifies the mobile terminal 300, and is represented, for example, by a string of characters or a number. "Time information" is information indicating the time when the individual radio 100 received mobile terminal information from the mobile terminal 300. "Location information" is information indicating the location of the mobile terminal 300, i.e., its latitude and longitude. "Motion information" is information indicating the movement of the mobile terminal 300, i.e., its speed.

[0036] In other words, in the example shown in Figure 4, it is shown that mobile terminal information is acquired from the mobile terminal 300A indicated by the terminal-specific information "ID-1" at the time indicated by the time information "Time Information 1", and the position of the mobile terminal 300A at that time is stored as location information "Location Information 1", and the movement of the mobile terminal 300A is stored as movement information "Movement Information 1".

[0037] Furthermore, the mobile terminal information storage unit 122 is not limited to information relating to the items "terminal-specific information," "time information," "location information," and "movement information," but may store any other information relating to the mobile terminal 300.

[0038] (Regarding the evacuation terminal information storage unit) The evacuation terminal information storage unit 123 stores information related to evacuation terminals. The information stored in the evacuation terminal information storage unit 123 will be explained using Figure 5. Figure 5 is a diagram showing an example of the information stored in the evacuation terminal information storage unit according to this disclosure.

[0039] As shown in Figure 5, the evacuation terminal information storage unit 123 stores information related to the items of "terminal-specific information," "time information," "location information," and "movement information" of terminals that have been certified as evacuation terminals, linking them together.

[0040] Here, the "terminal-specific information," "time information," "location information," and "movement information" stored in the evacuation terminal information storage unit 123 are the same as the "terminal-specific information," "time information," "location information," and "movement information" stored in the individual radio information storage unit 121 and the mobile terminal information storage unit 122, so an explanation of their contents will be omitted.

[0041] In the example shown in Figure 5, the following are identified as evacuation terminals: the individual wireless transceiver 100, identified by terminal-specific information "ID-A"; the mobile terminal 300A, identified by terminal-specific information "ID-1"; and the mobile terminal 300C, identified by terminal-specific information "ID-3". It is shown that the "time information," "location information," and "movement information" of each are stored in these terminals.

[0042] Furthermore, the evacuation terminal information storage unit 123 is not limited to information relating to the items of "terminal-specific information," "time information," "location information," and "movement information," but may store any other information relating to the evacuation terminal.

[0043] (Regarding the first control unit) The first control unit 130 is a controller that manages and controls the individual wireless transceivers 100. The first control unit 130 is implemented by a CPU (Central Processing Unit) or MPU (Micro Processing Unit), etc., which executes various programs stored in the first memory unit 120 using RAM as the working area. Alternatively, the first control unit 130 may be implemented by an integrated circuit such as an ASIC (Application Specific Integrated Circuit) or FPGA (Field Programmable Gate Array).

[0044] As shown in Figure 2, the first control unit 130 includes a location information acquisition unit 131, a mobile terminal information acquisition unit 132, a first information generation unit 133, a mobile terminal connection management unit 134, and a first operation control unit 135. The first control unit 130 reads a program (software) from the first storage unit 120 and executes it to realize the location information acquisition unit 131, the mobile terminal information acquisition unit 132, the first information generation unit 133, the mobile terminal connection management unit 134, and the first operation control unit 135, and executes these processes. The first control unit 130 may execute these processes with a single CPU, or it may have multiple CPUs and execute these processes in parallel with multiple CPUs. These configurations will be described in order below.

[0045] The location information acquisition unit 131 acquires the location information of the individual wireless radio 100. For example, the location information acquisition unit 131 may acquire location information (latitude and longitude) measured based on radio waves received by a GPS (Global Positioning System) receiver or GNSS (Global Navigation Satellite System) receiver equipped in the individual wireless radio 100. Alternatively, for example, the location information acquisition unit 131 may transmit a location information acquisition request to the mobile terminal 300 via the first communication unit 110 and acquire the location information from the mobile terminal 300 that has received the location information acquisition request. The location information acquisition unit 131 stores the acquired location information of the individual wireless radio 100 in the individual wireless radio information storage unit 121. The location information acquisition unit 131 acquires the location information of the individual wireless radio 100 at predetermined time intervals. The location information acquisition unit 131 may acquire the movement information (speed) of the individual wireless radio 100 by calculating the amount of change in location information per predetermined time interval from the location information acquired at predetermined time intervals. Once the location information acquisition unit 131 has acquired the location information and movement information from the individual wireless radio 100, it may store them in the individual wireless radio information storage unit 121, linked to the terminal-specific information and time information of the individual wireless radio 100.

[0046] The mobile terminal information acquisition unit 132 acquires terminal-specific information, time information, location information, and movement information from the mobile terminal 300 as mobile terminal information. For example, the mobile terminal information acquisition unit 132 may send an information provision request to the mobile terminal 300 via the first communication unit 110 and acquire terminal-specific information, time information, location information, and movement information from the mobile terminal 300 that has accepted the information provision request. It is desirable that the mobile terminal information acquisition unit 132 be able to acquire terminal-specific information, time information, location information, and movement information from the mobile terminal 300 via the first communication unit 110 at predetermined time intervals. Once the mobile terminal information acquisition unit 132 has acquired terminal-specific information, time information, location information, and movement information from the mobile terminal 300, it stores this information acquired for each mobile terminal 300 as mobile terminal information in the mobile terminal information storage unit 122.

[0047] The first information generation unit 133 generates evacuation terminal information from information of the mobile terminal 300 that is determined to be moving together with the individual radio 100, based on the location information of the individual radio 100 and the mobile terminal 300. For example, the first information generation unit 133 compares the location information of the individual radio 100 and the location information of the mobile terminal 300 to determine whether the individual radio 100 and the mobile terminal 300 are located within a predetermined distance. In this case, the predetermined distance may be set to any value within the range in which it can be determined that the individual radio 100 and the mobile terminal 300 are moving together, for example, it may be set to within 3m. Next, the first information generation unit 133 reads the "terminal-specific information," "time information," "location information," and "movement information" of the individual radio 100 and the mobile terminal 300 that are determined to be moving together from the individual radio information storage unit 121 and the mobile terminal information storage unit 122, respectively, and combines these to generate evacuation terminal information. Once the first information generation unit 133 has generated evacuation terminal information, it stores the generated evacuation terminal information in the evacuation terminal information storage unit 123.

[0048] When the first information generation unit 133 detects the movement of the individual wireless radio 100, it identifies the mobile terminal 300 that is moving with the individual wireless radio 100 and generates evacuation terminal information. Specifically, the first information generation unit 133 detects whether the individual wireless radio 100 is moving from the time-series changes in the location information of the individual wireless radio 100 acquired by the location information acquisition unit 131. If the first information generation unit 133 detects that the individual wireless radio 100 is moving, it compares the location information of the individual wireless radio 100 with the location information of the mobile terminal 300 to identify the mobile terminal 300 that is moving with the individual wireless radio 100. Once the first information generation unit 133 has identified the mobile terminal 300 that is moving with the individual wireless radio 100, it reads the "terminal-specific information," "time information," "location information," and "movement information" of the individual wireless radio 100 and the mobile terminal 300 from the individual wireless radio information storage unit 121 and the mobile terminal information storage unit 122, respectively, and combines these to generate evacuation terminal information. Once the first information generation unit 133 has generated evacuation terminal information, it stores the generated evacuation terminal information in the evacuation terminal information storage unit 123.

[0049] The mobile terminal connection management unit 134 manages the connection status between the individual wireless radio 100 and the mobile terminals 300. For example, the mobile terminal connection management unit 134 manages the total number of mobile terminals 300 connected to the individual wireless radio 100 and ensures that the number does not exceed the maximum number of connections that can be made to the individual wireless radio 100. In addition, the mobile terminal connection management unit 134 manages connections with mobile terminals 300 based on the MAC (Media Access Control) addresses of the mobile terminals 300 that have been registered to connect in advance. That is, if an access request is made to the individual wireless radio 100 from a mobile terminal 300 with a MAC address other than that of a mobile terminal 300 that has been registered to connect in advance, the mobile terminal connection management unit 134 will not permit the connection to the individual wireless radio 100. The mobile terminal connection management unit 134 may store the MAC address information of the mobile terminals 300 that have been registered to connect in advance as mobile terminal registration information in the first storage unit 120.

[0050] The first operation control unit 135 controls the operation of the individual radio 100. When the emergency information receiving unit 111 of the individual radio 100 receives emergency information from the radio station 400, the first operation control unit 135 instructs the first beacon transmitting unit 112 to transmit evacuation terminal information as a beacon signal via the first beacon transmitting unit 112. That is, the beacon signal transmitted by the first beacon transmitting unit 112 based on the command of the first operation control unit 135 includes evacuation terminal information. Here, the first operation control unit 135 may instruct the first communication unit 110 to continue communication so that the contents stored in the first storage unit 120 of the individual radio 100 and the contents stored in the second storage unit 220 of the communication device 200 are synchronized as much as possible. For example, the first operation control unit 135 may instruct the first communication unit 110 to continue the process of transmitting the evacuation terminal information stored in the evacuation terminal information storage unit 123 to the communication device 200 until communication between the individual wireless transceiver 100 and the communication device 200 is interrupted. Alternatively, the first operation control unit 135 may instruct the first communication unit 110 to transmit the evacuation terminal information as a beacon signal via the first beacon transmitting unit 112, in addition to instructing the first communication unit 110.

[0051] (Communication equipment configuration) Next, the configuration of the communication device 200 will be described using Figure 6. Figure 6 is a diagram showing an example of the configuration of a communication device according to the first embodiment of this disclosure. As shown in Figure 6, the communication device 200 according to the first embodiment of this disclosure comprises a second communication unit 210, a second storage unit 220, and a second control unit 230. These configurations will be described in order below.

[0052] The second communication unit 210 connects the inside and outside of the communication device 200 so that they can communicate with each other, and transmits and receives information between the inside and outside of the communication device 200. The second communication unit 210 may be implemented by, for example, a NIC, a wireless LAN card, a Bluetooth® module, a WiFi® module, an antenna, etc. Here, the second communication unit 210 communicates with the first communication unit 110 of the individual wireless radio 100 and transmits and receives information to each other. The second communication unit 210 receives the contents stored in the first storage unit 120 of the individual wireless radio 100 and is preferably controlled to continue communication so as to be synchronized as possible with the contents stored in the second storage unit 220 of the communication device 200.

[0053] As shown in Figure 6, the second communication unit 210 includes a second beacon transmitting unit 211.

[0054] The second beacon transmitter 211 transmits a beacon signal containing information about non-evacuation terminals. The second beacon transmitter 211 transmits a beacon signal based on a command from the second operation control unit 232, which will be described later. By receiving the beacon signal, administrative officials can confirm information about non-evacuation terminals that are not moving with the individual wireless radio 100. Therefore, it becomes possible to identify individuals who have received emergency information but may not be taking evacuation action.

[0055] The second storage unit 220 is a memory device that stores various types of information. The second storage unit 220 comprises a main memory and an auxiliary memory. The main memory may be implemented by semiconductor memory elements such as RAM, ROM, or flash memory. The auxiliary memory may be implemented by hard disks, SSDs, optical discs, or the like.

[0056] As shown in Figure 6, the second storage unit 220 includes a household radio information storage unit 221, a mobile terminal information storage unit 222, and an evacuation terminal information storage unit 223. These configurations will be described in detail below.

[0057] The individual radio information storage unit 221 stores information about the individual radios 100 registered in the communication device 200. It is desirable that the information about the individual radios 100 stored in the individual radio information storage unit 221 be synchronized as much as possible with the information about the individual radios 100 stored in the individual radio information storage unit 121 of the individual radio 100, so that the same stored content is maintained. Therefore, a detailed explanation of the information stored in the individual radio information storage unit 221 is omitted.

[0058] The mobile terminal information storage unit 222 stores information about all mobile terminals 300 registered with the individual wireless transceivers 100 that are registered with the communication device 200. The information about mobile terminals 300 stored in the mobile terminal information storage unit 222 is the same as the information about mobile terminals 300 stored in the mobile terminal information storage unit 122 of the individual wireless transceiver 100. Therefore, a detailed explanation of the information stored in the mobile terminal information storage unit 222 is omitted.

[0059] The evacuation terminal information storage unit 223 stores the evacuation terminal information transmitted from the individual wireless radio 100. The evacuation terminal information stored in the evacuation terminal information storage unit 223 is the same as the evacuation terminal information stored in the evacuation terminal information storage unit 223 of the communication device 200. Therefore, a detailed explanation of the information stored in the evacuation terminal information storage unit 223 is omitted.

[0060] The second control unit 230 is a controller that manages and controls the communication device 200. The second control unit 230 is implemented by a CPU or MPU, etc., which executes various programs stored in the second memory unit 220 using RAM as the working area. Alternatively, the second control unit 230 may be implemented by an integrated circuit such as an ASIC or FPGA.

[0061] As shown in Figure 6, the second control unit 230 comprises a second information generation unit 231 and a second operation control unit 232. The second control unit 230 reads a program (software) from the second storage unit 220 and executes it, thereby realizing the second information generation unit 231 and the second operation control unit 232 and executing their respective processes. The second control unit 230 may execute these processes using a single CPU, or it may have multiple CPUs and execute these processes in parallel using multiple CPUs. This configuration will be described in detail below.

[0062] The second information generation unit 231 generates non-evacuation terminal information, other than evacuation terminals, based on the evacuation terminal information, terminal-specific information, and movement information stored in the second storage unit 220 of the communication device 200. The second information generation unit 231 identifies mobile terminals 300 that are not included in the evacuation terminal information among the mobile terminals 300 registered with the individual radio 100 as non-evacuation terminals. The second information generation unit 231 reads the "terminal-specific information," "time information," "location information," and "movement information" of the individual radio 100 connected to the mobile terminal 300 identified as a non-evacuation terminal from the individual radio information storage unit 221 and the mobile terminal information storage unit 222, respectively, and combines these to generate non-evacuation terminal information.

[0063] The second operation control unit 232 controls the second operation control unit 220 to acquire information stored in the first storage unit 120 of the individual radio 100 and store it in the second storage unit 220. Here, the second operation control unit 232 acquires information stored in the individual radio information storage unit 121, the mobile terminal information storage unit 122, and the evacuation terminal information storage unit 123, and then stores this information in the individual radio information storage unit 221, the mobile terminal information storage unit 222, and the evacuation terminal information storage unit 223 of the second storage unit 220, respectively. When a communication interruption with the individual radio 100 is detected, a command is given to the second beacon transmitting unit 211 to transmit beacon information. The second operation control unit 232 retrieves the information that was stored in the first storage unit 120 of the individual radio 100, which was acquired before communication with the individual radio 100 was interrupted and stored in the second storage unit 220 of the communication device 200, that is, the information stored in the individual radio information storage unit 221, the mobile terminal information storage unit 222, and the evacuation terminal information storage unit 223. When the second operation control unit 232 detects that communication with the individual radio 100 has been interrupted, it retrieves the non-evacuation terminal information generated by the second information generation unit 231 based on the information acquired just before the communication was interrupted and stored in the second storage unit 220, and gives a command to the second beacon transmitting unit 211 to transmit beacon information. The beacon signal transmitted by the second beacon transmitting unit 211 includes the non-evacuation terminal information generated by the second information generation unit 231.

[0064] (Second Embodiment) (Disaster prevention radio communication system) Next, the disaster prevention wireless communication system 1 according to the second embodiment will be described with reference to Figure 7. Figure 7 is a diagram showing the configuration of the disaster prevention wireless communication system according to the second embodiment of this disclosure, and the relationship between the disaster prevention wireless communication system according to the second embodiment and other configurations.

Also, unlike the disaster prevention wireless communication system 1 according to the first embodiment, the communication device 200 is connected to a mobile terminal 300 so that they can communicate with each other using radio waves RW.

[0065] Next, an overview of the processing of the disaster prevention radio communication system 1 according to the second embodiment will be described. When the individual radio 100 receives emergency information from the radio station 400, it transmits reception notification information to the communication device 200, notifying that it has received the emergency information. The communication device 200 receives the reception notification information from the individual radio 100, acquires terminal-specific information and motion information from the mobile terminal 300 connected to the communication device 200, and stores it in the second storage unit 220. The communication device 200 transmits update notification information to the individual radio 100, indicating that the information in the second storage unit 220 of the communication device 200 has been updated. The individual radio 100 receives the update notification information, acquires the information stored in the second storage unit 220 of the communication device 200, and updates the information in the first storage unit 120 of the individual radio 100. When the communication device 200 receives the reception notification information and detects a loss of communication with the individual radio 100, it transmits beacon information.

These configurations will be described in order below.

[0067] The first communication unit 110 is the same as the first communication unit 110 of the individual radio 100 according to the first embodiment, except that the first beacon transmitter 112 is removed.

[0068] The first storage unit 120 is the same as the first storage unit 120 of the individual wireless radio 100 according to the first embodiment. Therefore, the description of the first storage unit 120 of the individual wireless radio 100 according to the second embodiment will be omitted.

[0069] The first control unit 130 of the second embodiment of the home radio 100 is the same as the first control unit 130 of the home radio 100 of the first embodiment, except that the location information acquisition unit 131, the mobile terminal information acquisition unit 132, the first information generation unit 133, the mobile terminal connection management unit 134, and the first operation control unit 135 are omitted.

These configurations will be described in order below.

[0071] The second communication unit 210 is the same as the second communication unit 210 of the communication device 200 according to the first embodiment.

The following describes the parts of the processing of the second control unit 230 according to the second embodiment that differ from the processing of the second control unit 230 according to the first embodiment.

[0074] When the location information acquisition unit 233 receives a reception notification from the individual radio 100, it acquires location information from the individual radio 100 connected to the communication device 200 and stores it in the individual radio information storage unit 221. The location information acquisition unit 233 acquires location information from the individual radio 100 at predetermined time intervals. The location information acquisition unit 233 may acquire movement information (speed) of the individual radio 100 by calculating the amount of change in location information per predetermined time interval from the location information acquired at predetermined time intervals. Once the location information acquisition unit 233 has acquired location information and movement information from the individual radio 100, it may store them in the individual radio information storage unit 221, linked to the terminal-specific information and time information of the individual radio 100.

[0075] When the mobile terminal information acquisition unit 234 receives a reception notification from the individual wireless radio 100, it acquires terminal-specific information and motion information from the mobile terminal 300 connected to the communication device 200 and stores it in the mobile terminal information storage unit 222 of the second storage unit 220. In other words, in the disaster prevention wireless communication system 1 according to the second embodiment, since the mobile terminal 300 is connected to the communication device 200, the mobile terminal information acquisition unit 234 of the communication device 200 acquires terminal-specific information and motion information of the mobile terminal 300 connected to the communication device 200, and stores this acquired information in the mobile terminal information storage unit 222 for each mobile terminal 300.

[0076] The mobile terminal connection management unit 235 is the same as the mobile terminal connection management unit 134 of the individual wireless transceiver 100 according to the first embodiment, so its description is omitted.

[0077] (Third embodiment) (Disaster prevention radio communication system) Next, a disaster prevention wireless communication system 1 according to the third embodiment will be described. The disaster prevention wireless communication system 1 according to the third embodiment includes individual wireless transceivers 100 and a communication device 200, just like the disaster prevention wireless communication system 1 according to the first embodiment.

[0078] The processing outline of the disaster prevention wireless communication system 1 according to the third embodiment will now be described. The individual wireless radio 100 communicates with a mobile terminal 300 and a communication device 200. When the individual wireless radio 100 receives emergency information from the radio station 400, it acquires terminal-specific information and motion information from the connected mobile terminal 300 and stores it in the first storage unit 120. The individual wireless radio 100 transmits reception notification information to the communication device 200, notifying that it has received emergency information. The communication device 200 receives the reception notification information from the individual wireless radio 100, acquires the information stored in the first storage unit 120 of the individual wireless radio 100, and updates the information in the second storage unit 220 of the communication device 200.

[0079] (Individual radio transceivers) Next, the individual wireless radio 100 according to the third embodiment will be described with reference to Figure 10. Figure 10 is a diagram showing an example of the configuration of the individual wireless radio according to the third embodiment of this disclosure. As shown in Figure 10, the individual wireless radio 100 according to this disclosure comprises a first communication unit 110, a first storage unit 120, and a first control unit 130. These configurations will be described in order below.

[0080] The first communication unit 110 of the home radio 100 according to the first embodiment is modified by removing the first beacon transmitter 112. In other words, the first communication unit 110 of the home radio 100 according to the third embodiment does not transmit beacon signals. Aside from this, the first communication unit 110 of the home radio 100 according to the third embodiment is the same as the first communication unit 110 of the home radio 100 according to the first embodiment. Therefore, a description of the first communication unit 110 of the home radio 100 according to the third embodiment will be omitted.

[0081] The first storage unit 120 is the same as the first storage unit 120 of the individual wireless radio 100 according to the first embodiment. Therefore, the description of the first storage unit 120 of the individual wireless radio 100 according to the third embodiment will be omitted.

[0082] The first control unit 130 of the third embodiment is the same as the first control unit 130 of the individual wireless radio 100 according to the first embodiment, but without the first information generation unit 133.

Aside from this, the first control unit 130 of the individual wireless radio 100 according to the third embodiment is the same as the first control unit 130 of the individual wireless radio 100 according to the first embodiment. Therefore, the description of the first control unit 130 of the individual wireless radio 100 according to the third embodiment will be omitted.

[0083] (Communication equipment) Next, the communication device 200 according to the third embodiment will be described with reference to Figure 11. Figure 11 is a diagram showing an example of the configuration of the communication device according to the third embodiment of this disclosure. As shown in Figure 11, the communication device 200 according to the third embodiment of this disclosure comprises a second communication unit 210, a second storage unit 220, and a second control unit 230. These configurations will be described in order below.

[0084] The second communication unit 210 is the same as the second communication unit 210 of the communication device 200 according to the first embodiment. Therefore, the description of the second communication unit 210 of the communication device 200 according to the third embodiment will be omitted.

[0085] The second storage unit 220 is the same as the second storage unit 220 of the communication device 200 according to the first embodiment. Therefore, the description of the second storage unit 220 of the communication device 200 according to the third embodiment will be omitted.

[0086] The second control unit 230 is the same as the second control unit 230 of the communication device 200 according to the first embodiment, but without the second information generation unit 231 and the second operation control unit 232. Furthermore, the second control unit 230 includes a stored information acquisition unit 236 and a beacon signal generation unit 237. Aside from this, the second control unit 230 of the communication device 200 according to the third embodiment is the same as the second control unit 230 of the communication device 200 according to the first embodiment. Therefore, the part of the processing of the second control unit 230 according to the third embodiment that differs from the second control unit 230 according to the first embodiment will be explained.

[0087] The information acquisition unit 236 acquires information stored in the first storage unit 120 from the individual radio 100. Specifically, the information acquisition unit 236 acquires information stored in the individual radio information storage unit 221, the mobile terminal information storage unit 222, and the evacuation terminal information storage unit 223 of the first storage unit 120 from the individual radio 100. Once the information acquisition unit 236 has acquired the information stored in the individual radio information storage unit 121, the mobile terminal information storage unit 122, and the evacuation terminal information storage unit 123 of the first storage unit 120 of the individual radio 100, it stores the acquired information in the individual radio information storage unit 221, the mobile terminal information storage unit 222, and the evacuation terminal information storage unit 223 of the second storage unit 220 of the communication device 200.

[0088] The beacon signal generation unit 237 generates a beacon signal to be transmitted by the second beacon transmission unit 211. The beacon signal generation unit 237 reads evacuation terminal information from the evacuation terminal information storage unit 223 and generates a beacon signal that includes the read evacuation terminal information. When the beacon signal generation unit 237 detects a communication interruption with the individual wireless radio 100, it issues a command to the second beacon transmission unit 211 to transmit the generated beacon signal.

[0089] (Disaster prevention radio communication methods and programs) Next, the disaster prevention wireless communication method and program related to this disclosure will be explained using Figure 12. Figure 12 is a flowchart of the disaster prevention wireless communication method related to this disclosure. The disaster prevention wireless communication method and program related to this disclosure will be explained in accordance with the flowchart shown in Figure 12.

[0090] First, the disaster prevention radio communication system 1 receives emergency information from the radio station 400 (step S1). Next, the disaster prevention radio communication system 1 acquires location information of the individual radio 100 and the mobile terminal 300 (step S2). Next, the disaster prevention radio communication system 1 acquires terminal-specific information, time information, location information, and movement information from the mobile terminal 300 (step S3). Next, based on the location information of the individual radio 100 and the mobile terminal 300, the disaster prevention radio communication system 1 generates evacuation terminal information from the information of the mobile terminal 300 that is determined to be moving together with the individual radio 100 (step S4). Next, the disaster prevention radio communication system 1 stores the information acquired in the step of acquiring information from the mobile terminal 300 and the information generated in the generation step (step S5). Next, the disaster prevention radio communication system 1 transmits a beacon signal including the unique information of the individual radio 100 and the evacuation terminal information (step S6).

[0091] The above-described disaster prevention radio communication method may be implemented using the disaster prevention radio communication system 1, or by any other arbitrary means. Furthermore, the above-described disaster prevention radio communication method can also be implemented by a program that causes the computers in the first control unit 130 of the individual radio transceiver 100 or the second control unit 230 of the communication device 200 to perform the processing.

[0092] According to this, when emergency information is transmitted from the radio station 400, it becomes possible to obtain information from the mobile terminal 300 that is moving along with the individual radio receiver 100 that received the emergency information. Therefore, it is possible to provide a disaster prevention radio communication method and program that allows administrators such as local governments to easily understand the evacuation actions of people who require assistance during evacuation.

[0093] (Structure and effect) The individual wireless radio 100 relating to this disclosure is an individual wireless radio 100 that communicates with a mobile terminal 300 and a communication device 200, and includes an emergency information receiving unit 111 that receives emergency information from a radio station 400, a location information acquisition unit 131 that acquires the location information of the unit itself, a first communication unit 110 that connects with the mobile terminal 300 and the communication device 200 and transmits and receives information, a mobile terminal information acquisition unit 132 that acquires terminal-specific information, time information, location information, and movement information of the mobile terminal 300 as mobile terminal information from the information received by the first communication unit 110, and a first information generation unit that determines whether the mobile terminal 300 is moving with the unit based on the location information of the unit itself and the location information of the mobile terminal 300, and generates evacuation terminal information from the mobile terminal information of the mobile terminal 300 that is determined to be moving with the unit itself. The unit comprises a first storage unit 120 that stores mobile terminal registration information, which is information of mobile terminals 300 authorized to connect to the unit, the unit's location information, mobile terminal information acquired by the mobile terminal information acquisition unit 132, and evacuation terminal information generated by the first information generation unit 133, a first beacon transmission unit 112 that transmits a beacon signal, and a first operation control unit 135 that controls the operation of the unit. When the emergency information receiving unit 111 receives emergency information, the first operation control unit 135 controls the first communication unit 110 to transmit the mobile terminal registration information, the unit's location information, mobile terminal information, and evacuation terminal information stored in the first storage unit 120 to the communication device 200, and controls the first beacon transmission unit 112 to transmit the evacuation terminal information as a beacon signal.

[0094] This configuration allows for the identification of a portable terminal 300 that is registered with the individual wireless radio 100 that received the emergency information and is moving with the individual wireless radio 100, and enables the transmission of a beacon signal containing information about this terminal as evacuation terminal information. As a result, administrative officials can easily determine whether or not a person requiring evacuation assistance who owns the individual wireless radio 100 that received the emergency information is actually evacuating.

[0095] The disaster prevention radio communication system 1 relating to this disclosure comprises a communication device 200 and a household radio 100 that receives emergency information from a radio station 400 and communicates with a mobile terminal 300 and the communication device 200, wherein the household radio 100 includes an emergency information receiving unit 111 that receives emergency information from the radio station 400, a location information acquisition unit 131 that acquires its own location information, a first communication unit 110 that connects to the mobile terminal 300 and the communication device 200 and transmits and receives information, and information received by the first communication unit 110 A mobile terminal information acquisition unit 132 acquires terminal-specific information, time information, location information, and movement information of the mobile terminal 300 as mobile terminal information; a first information generation unit 133 determines whether the mobile terminal 300 is moving with the aircraft based on the aircraft's location information and the mobile terminal 300's location information, and generates evacuation terminal information from the mobile terminal information of the mobile terminal 300 that is determined to be moving with the aircraft; mobile terminal registration information, which is information of the mobile terminal 300 that is permitted to connect to the aircraft, the aircraft's location information, and the mobile terminal information acquisition unit 132. The communication device 200 includes a first storage unit 120 that stores mobile terminal information acquired in 32 and evacuation terminal information generated by the first information generation unit 133, a first beacon transmitting unit 112 that transmits beacon signals, and a first operation control unit 135 that controls the operation of the device itself. The communication device 200 is connected to the individual radio 100 and includes a second communication unit 210 that transmits and receives information, a second storage unit 220 that stores information transmitted from the individual radio 100, and a second information unit that generates non-evacuation terminal information other than evacuation terminals based on mobile terminal registration information and evacuation terminal information. The system comprises a report generation unit 231, a second beacon transmission unit 211 that transmits a beacon signal, and a second operation control unit 232 that controls the operation of the communication device 200. When a communication interruption with the individual wireless device 100 is detected, the second operation control unit 232 controls the second information generation unit 231 to generate non-evacuation terminal information based on the mobile terminal registration information and evacuation terminal information stored in the second storage unit 220 up to the moment immediately before the communication interruption, and controls the second beacon transmission unit 211 to transmit the non-evacuation terminal information as a beacon signal.

[0096] This configuration makes it possible to identify portable terminals 300 that are registered with the individual radio 100 that received emergency information but are not moving with the individual radio 100, and to transmit a beacon signal containing information about these terminals as non-evacuation terminal information. As a result, administrative officials can easily identify individuals who possess the individual radio 100 that received emergency information but are not believed to be taking evacuation action.

[0097] The first operation control unit 135 of the disaster prevention wireless communication system 1 according to this disclosure detects the movement of the individual wireless radio 100, identifies the mobile terminal 300 that is moving with the individual wireless radio 100, generates evacuation terminal information, and controls the system to continue the process of transmitting the information stored in the first storage unit 120 to the communication device 200 until communication between the individual wireless radio 100 and the communication device 200 is interrupted.
