Description

This disclosure relates to a home radio, a disaster prevention wireless communication system, a disaster prevention wireless communication method, and a program.

Currently, disaster prevention radio systems in general use include audio broadcasts using loudspeakers and individual receivers via disaster prevention administrative radio. Ordinary residents make emergency decisions based on the broadcasts from the disaster prevention administrative radio, and if damage is expected to affect their homes, they evacuate to designated evacuation sites such as community centers. Local governments that broadcast evacuation information using the disaster prevention administrative radio are required to know whether people who need assistance in evacuating have checked the evacuation information and evacuated to the designated evacuation site.

For example, the following Patent Document 1 discloses a crime prevention and disaster prevention information system that can confirm the safety of people evacuating to evacuation shelters such as community centers.

JP 2005-251088 A

However, in the crime prevention and disaster prevention information system of Patent Document 1, safety information is input exclusively through a safety information input means installed at the evacuation shelter, so it is not possible to grasp the progress of the evacuation of a person requiring assistance with evacuation or to grasp whether the person is staying at home for some reason. In addition, the means of transmitting disaster prevention information implemented by local governments are one-way, such as broadcasting using loudspeakers to the general public or transmitting evacuation information to individual receivers, so it is not easy to confirm the safety of residents in dangerous areas when a disaster occurs. For this reason, local government officials visit the homes of people requiring assistance with evacuation individually as necessary to check on the status of those.

In consideration of the above problems, the present disclosure aims to provide a door-to-door radio, a disaster prevention wireless communication system, a disaster prevention wireless communication method, and a program that allow managers of local governments and other organizations to easily grasp the evacuation actions of people who require assistance in evacuation.

Embodiments of the present disclosure are described in detail below with reference to the drawings. Note that the present disclosure is not limited to the embodiments described below.

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 house radio device 100 and a communication device 200. Also, as shown in FIG. 1, the house radio device 100 constituting the disaster prevention wireless communication system 1 is connected to a mobile terminal 300 (300A, 300B, 300C) so as to be able to communicate with each other via radio waves RW. Also, as shown in FIG. 1, the house radio device 100 receives emergency information DRW transmitted from a wireless station 400. Below, after briefly describing these configurations, an overview 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 a wireless station 400, but may be a wireless station that transmits emergency information. The emergency information transmitted from the wireless station may be special warnings, alerts, and advisories for weather such as rain, floods, and high tides, avalanche advisories, landslide warnings, emergency earthquake alerts, tsunami warnings, flooding information for rivers and the like, eruption warnings, disaster information, special warnings, alerts for birds and animals, suspicious people, and other emergency information, etc. Any disaster prevention wireless communication system 1 may be used as long as it receives such emergency information and performs processing based on the received information.

The individual door radio 100 is a radio that is placed in each household within the area under the jurisdiction of the local government. When an evacuation order is issued by the local government, the individual door radio 100 can be taken by the person requiring assistance with evacuation, and guides the person requiring assistance with evacuation to an evacuation site. When guiding an evacuation using the individual door radio 100, the individual door radio 100 moves while emitting a beacon signal to the surrounding area, informing nearby residents and government officials that the person requiring assistance with evacuation is evacuating.

The individual door radio 100 may be, for example, a digital mobile disaster prevention administrative radio capable of receiving radio waves in the 260 MHz band. The modulation method used for the digital mobile disaster prevention administrative radio may be a π/4 shift QPSK (Quadraphase Shift Keying) method or a 4-value FSK (Frequency Shift Keying) method. In addition, the right to use the transmission line may be assigned by 4-slot TDMA (Time Division multiple access) to enable multiple access. This makes it possible to directly call individual terminals, and to realize data communication such as multi-channelization and image transfer. The individual door radio 100 receives disaster prevention radio waves from, for example, a radio station 400.

The communication device 200 is a base station or a simplified base station that manages the individual door radio device 100. The communication device 200 receives information transmitted from the individual door radio device 100 and performs processing based on the received information.

The mobile terminal 300 is a communication terminal that can be carried by a person who requires assistance with 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 a GNSS (Global Navigation Satellite System) receiver provided in the mobile terminal 300. The mobile terminal 300 may be any portable communication terminal that has a function for measuring location information and a function for communicating with the individual door radio 100 using Wi-Fi (registered trademark) communication, i.e., wireless LAN (Local Area Network) communication, and may be, for example, a communication terminal such as a smartphone, a tablet terminal, a notebook PC, a mobile phone, or a PDA (Personal Digital Assistant).

The radio station 400 is a base station that transmits disaster prevention radio waves (radio waves in the 60 MHz or 260 MHz band). The radio station 400 is installed, for example, in a city or town hall, and when a disaster occurs in the city or town, it transmits various types of emergency information to residents via the individual door-to-door radio device 100 using disaster prevention radio waves. The radio station 400 is equipped, for example, with an antenna and a transmitter, and transmits emergency information as disaster prevention radio waves.

Next, an overview of the processing of the disaster prevention wireless communication system 1 will be described. First, the door-to-door radio 100 receives emergency information from the wireless station 400. When the door-to-door radio 100 receives emergency information, it acquires location information at a predetermined time interval from the mobile terminal 300 connected to the door-to-door radio 100 among the mobile terminals 300 registered in advance so that they can be connected to the door-to-door radio 100, and compares the location information with the location information of the door-to-door radio 100 to determine whether or not the mobile terminal 300 is moving within a predetermined range from the location of the door-to-door radio 100. When the door-to-door radio 100 is taken out, the door-to-door radio 100 continues to transmit information stored in the door-to-door radio 100, including unique information of the mobile terminal 300 that has moved and evacuated with the door-to-door radio 100, 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 household radio 100, and when the household radio 100 is taken out in response to an evacuation order, it transmits a beacon signal indicating that the household that took out the household radio 100 is evacuating toward the periphery of the house in which it is installed, informing passing neighbors and government officials. The beacon signal transmitted from the communication device 200 includes unique information of the mobile terminal 300 that was identified based on information stored in the household radio 100 and that may have not evacuated with the household radio 100 and may have been too late to evacuate.

(Configuration of individual door-to-door radio devices)
Next, the configuration of the home radio device 100 will be described with reference to Fig. 2. Fig. 2 is a diagram showing an example of the configuration of the home radio device according to the first embodiment of the present disclosure. As shown in Fig. 2, the home radio device 100 includes a first communication unit 110, a first storage unit 120, and a first control unit 130. Below, these components will be described in order.

(Regarding the first communication unit)
The first communication unit 110 connects the inside and outside of the home radio 100 so that they can communicate with each other, and transmits and receives information between the inside and outside of the home radio 100. The first communication unit 110 may be realized by, for example, a network interface card (NIC), a wireless local area network (LAN) card, a Bluetooth (registered trademark) module, a WiFi (registered trademark) module, an antenna, or the like. Here, the first communication unit 110 is communicatively connected to a second communication unit 210 of the communication device 200 described below, and transmits and receives information between them. The process of transmitting the information stored in the first storage unit 120 to the communication device 200 may be continued until communication between the home radio 100 and the communication device 200 is interrupted. For example, the contents of communication until communication is interrupted may include information about the household radio 100 stored in a household radio information storage unit 121 described below, information about the mobile terminal 300 stored in a mobile terminal information storage unit 122, and information about the evacuation terminal stored in an evacuation terminal information storage unit 123. Until communication between the household radio 100 and the communication device 200 is interrupted, communication may be continued such that the contents stored in the first storage unit 120 of the household radio 100 and the contents stored in the second storage unit 220 of the communication device 200 are synchronized as much as possible.

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

The emergency information receiving unit 111 receives emergency information from the wireless station 400. That is, the emergency information receiving unit 111 receives emergency information transmitted from the wireless station 400 as disaster prevention radio waves. The emergency information receiving unit 111 may include an antenna for receiving radio waves in the 60 MHz band or 260 MHz band, at which the emergency information is transmitted as radio waves, and may receive the emergency information via the antenna. When the emergency information receiving unit 111 receives emergency information from the wireless station 400, it transmits reception notification information to the communication device 200 notifying the communication device 200 that the emergency information has been received.

The first beacon transmitter 112 transmits a beacon signal including the evacuation terminal information. The first beacon transmitter 112 transmits the 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 capable of receiving the beacon signal transmitted by the household radio 100, the administrative staff can confirm the evacuation terminal information moving with the household radio 100, and can grasp the situation of the person who needs assistance in evacuation who received the emergency information. In addition, the first communication unit 110 may 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 household radio 100 and the communication device 200 is interrupted. At that time, the first beacon transmitter 112 may transmit the evacuation terminal information by including it in the beacon signal.

(Regarding the first storage unit)
The first storage unit 120 is a storage device that stores various types of information. The first storage unit 120 includes a main storage device and an auxiliary storage device. The main storage device may be realized by a semiconductor memory element such as a random access memory (RAM), a read only memory (ROM), or a flash memory. The auxiliary storage device may be realized by a hard disk, a solid state drive (SSD), an optical disk, or the like.

As shown in FIG. 2, the first storage unit 120 includes a door-to-door radio information storage unit 121, a mobile device information storage unit 122, and an evacuation terminal information storage unit 123. The first storage unit 120 stores mobile device registration information (described below), location information of the door-to-door radio 100 itself, mobile device information acquired by the mobile device information acquisition unit 132, and evacuation terminal information generated by the first information generation unit 133. The components are described below in order.

(About the door-to-door radio information storage unit)
The door-to-door radio information storage unit 121 stores information related to the door-to-door radio 100. Here, the information stored in the door-to-door radio information storage unit 121 will be described with reference to Fig. 3. Fig. 3 is a diagram showing an example of information stored in the door-to-door radio information storage unit according to the present disclosure.

In the example shown in FIG. 3, the household radio information storage unit 121 stores information related to the items "terminal specific information," "time information," "location information," and "movement information" in association with each other.

"Terminal-specific information" is an identifier that identifies the household radio 100, and is represented by, for example, a character string or a number. "Time information" is information that indicates the time when the household radio 100 received the emergency information from the wireless station 400. "Location information" is information that indicates the location of the household radio 100, i.e., the latitude and longitude. "Movement information" is information that indicates the movement of the household radio 100, i.e., the speed.

In other words, FIG. 3 shows that the household radio 100 indicated by the terminal-specific information "ID-A" received emergency information from the radio station 400 at the time indicated by the time information "time information A," and that the position of the household radio 100 at that time is stored as position information "position information A," and the movement of the household radio 100 is stored as movement information "movement information A."

The household radio information storage unit 121 is not limited to information related to the items "terminal-specific information," "time information," "location information," and "movement information," and may store other information related to any household radio 100.

(Regarding the mobile terminal information storage unit)
The mobile terminal information storage unit 122 stores information related to the mobile terminal 300. Here, the information stored in the mobile terminal information storage unit 122 will be described with reference to Fig. 4. Fig. 4 is a diagram showing an example of information stored in the mobile terminal information storage unit according to the present disclosure.

In the example shown in FIG. 4, the mobile device information storage unit 122 stores information related to the items of "device-specific information," "time information," "location information," and "movement information" in association with each other.

"Terminal-specific information" is an identifier that identifies the mobile terminal 300, and is represented by, for example, a character string or a number. "Time information" is information that indicates the time when the individual door radio 100 received the mobile terminal information from the mobile terminal 300. "Location information" is information that indicates the location of the mobile terminal 300, i.e., the latitude and longitude. "Movement information" is information that indicates the movement of the mobile terminal 300, i.e., the speed.

In other words, in the example shown in FIG. 4, mobile terminal information was obtained 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 was stored as position information "position information 1," and the movement of the mobile terminal 300A was stored as movement information "movement information 1."

The mobile device information storage unit 122 is not limited to information related to the items "device-specific information," "time information," "location information," and "movement information," and may store information related to any other mobile device 300.

(Regarding the evacuation terminal information storage unit)
The evacuation terminal information storage unit 123 stores information related to the evacuation terminal. Here, the information stored in the evacuation terminal information storage unit 123 will be described with reference to Fig. 5. Fig. 5 is a diagram showing an example of information stored in the evacuation terminal information storage unit according to the present disclosure.

As shown in FIG. 5, the evacuation terminal information storage unit 123 stores information relating to the items of "terminal-specific information," "time information," "location information," and "movement information" of a terminal that has been identified as an evacuation terminal in association with each other.

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 door-to-door radio information storage unit 121 and the mobile terminal information storage unit 122, and therefore a description of their contents will be omitted.

In the example shown in FIG. 5, the door-to-door radio 100 indicated by the terminal-specific information "ID-A", the mobile terminal 300A indicated by the terminal-specific information "ID-1", and the mobile terminal 300C indicated by the terminal-specific information "ID-3" are recognized as evacuation terminals, and their respective "time information", "location information", and "movement information" are stored.

The evacuation terminal information storage unit 123 is not limited to information related to the items "terminal-specific information," "time information," "location information," and "movement information," and may store information related to any other evacuation terminal.

(Regarding the first control unit)
The first control unit 130 is a controller that manages and controls the individual door radio device 100. The first control unit 130 is realized by a central processing unit (CPU), a micro processing unit (MPU), or the like executing various programs stored in the first storage unit 120 using a RAM as a working area. The first control unit 130 may also be realized by an integrated circuit such as an application specific integrated circuit (ASIC) or a field programmable gate array (FPGA).

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 realizes 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 by reading and executing a program (software) from the first storage unit 120. The first control unit 130 may execute these processes using one CPU, or may include multiple CPUs and execute these processes in parallel using the multiple CPUs. Below, these configurations will be explained in order.

The location information acquisition unit 131 acquires location information of the home radio device 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 a GNSS (Global Navigation Satellite System) receiver provided in the home radio device 100. Also, for example, the location information acquisition unit 131 may transmit a request to acquire location information to the mobile terminal 300 via the first communication unit 110 and acquire location information from the mobile terminal 300 that has accepted the request to acquire location information. The location information acquisition unit 131 stores the acquired location information of the home radio device 100 in the home radio device information storage unit 121. The location information acquisition unit 131 acquires the location information of the home radio device 100 at a predetermined time interval. The location information acquisition unit 131 may acquire movement information (speed) of the door-to-door radio 100 by calculating the amount of change in the location information per predetermined time interval from the location information acquired at a predetermined time interval. After acquiring the location information and movement information from the door-to-door radio 100, the location information acquisition unit 131 may associate the information with the terminal-specific information and time information of the door-to-door radio 100 and store the information in the door-to-door radio information storage unit 121.

The mobile device information acquisition unit 132 acquires the terminal-specific information, time information, location information, and movement information of the mobile device 300 from the mobile device 300 as mobile device information. For example, the mobile device information acquisition unit 132 may transmit an information provision request to the mobile device 300 via the first communication unit 110 and acquire the terminal-specific information, time information, location information, and movement information from the mobile device 300 that has accepted the information provision request. The mobile device information acquisition unit 132 may acquire the terminal-specific information, time information, location information, and movement information from the mobile device 300 at a predetermined time interval via the first communication unit 110. After acquiring the terminal-specific information, time information, location information, and movement information from the mobile device 300, the mobile device information acquisition unit 132 stores the information acquired for each mobile device 300 in the mobile device information storage unit 122 as mobile device information.

The first information generating unit 133 generates evacuation terminal information from the information of the mobile terminal 300 that is determined to be moving together with the home radio 100, based on the position information of the home radio 100 and the mobile terminal 300. For example, the first information generating unit 133 compares the position information of the home radio 100 with the position information of the mobile terminal 300, and determines whether the home 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 a range in which it can be determined that the home radio 100 and the mobile terminal 300 are moving together, and may be set to within 3 m, for example. Next, the first information generating unit 133 reads out the "terminal specific information," "time information," "position information," and "movement information" of the home radio 100 and the mobile terminal 300 that are determined to be moving together from the home radio information storage unit 121 and the mobile terminal information storage unit 122, respectively, and generates evacuation terminal information by combining these. After generating the evacuation terminal information, the first information generation unit 133 stores the generated evacuation terminal information in the evacuation terminal information storage unit 123.

When the first information generating unit 133 detects the movement of the door-to-door radio 100, it identifies the mobile terminal 300 that is moving with the door-to-door radio 100 and generates evacuation terminal information. That is, the first information generating unit 133 detects whether the door-to-door radio 100 is moving or not from the time series change in the position information of the door-to-door radio 100 acquired by the position information acquiring unit 131. When the first information generating unit 133 detects that the door-to-door radio 100 is moving, it compares the position information of the door-to-door radio 100 with the position information of the mobile terminal 300 and identifies the mobile terminal 300 that is moving with the door-to-door radio 100. When the first information generating unit 133 identifies the mobile terminal 300 that is moving with the door-to-door radio 100, it reads out the "terminal specific information," "time information," "position information," and "movement information" of the door-to-door radio 100 and the mobile terminal 300 from the door-to-door radio information storing unit 121 and the mobile terminal information storing unit 122, respectively, and generates these together as evacuation terminal information. After generating the evacuation terminal information, the first information generation unit 133 stores the generated evacuation terminal information in the evacuation terminal information storage unit 123.

The mobile terminal connection management unit 134 manages the connection state between the house radio 100 and the mobile terminal 300. For example, the mobile terminal connection management unit 134 manages the total number of mobile terminals 300 connected to the house radio 100 so as not to exceed the maximum number of connections that can be connected to the house radio 100. The mobile terminal connection management unit 134 also manages the connection with the mobile terminal 300 using the MAC (Media Access Control) address of the mobile terminal 300 that has been registered in advance so that it can be connected. That is, when the mobile terminal 300 having a MAC address other than the MAC address of the mobile terminal 300 that has been registered in advance so that it can be connected accesses the house radio 100, the mobile terminal connection management unit 134 does not allow the connection to the house radio 100. The mobile terminal connection management unit 134 may store the MAC address information of the mobile terminal 300 that has been registered in advance so that it can be connected in the first storage unit 120 as mobile terminal registration information.

The first operation control unit 135 controls the operation of the household radio 100. When the emergency information receiving unit 111 of the household radio 100 receives emergency information from the wireless station 400, the first operation control unit 135 instructs the first beacon transmitting unit 112 to transmit the 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 instruction of the first operation control unit 135 includes the evacuation terminal information. Here, the first operation control unit 135 may instruct the first communication unit 110 to continue communication so that the memory contents in the first memory unit 120 of the household radio 100 and the memory contents in the second memory 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 door radio device 100 and the communication device 200 is interrupted. In addition to instructing the first communication unit 110, the first operation control unit 135 may also instruct the first beacon transmission unit 112 to include the evacuation terminal information in a beacon signal and transmit it.

As shown in FIG. 6, the second communication unit 210 includes a second beacon transmission unit 211.

The second beacon transmitter 211 transmits a beacon signal including non-evacuation terminal information. The second beacon transmitter 211 transmits the beacon signal based on commands from the second operation controller 232, which will be described later. By receiving the beacon signal, administrative personnel can confirm information about non-evacuation terminals that are not moving with the individual door-to-door wireless device 100. This makes it possible to identify those who need assistance with evacuation and who have received emergency information, but who may not be taking evacuation action.

The second storage unit 220 is a storage device that stores various types of information. The second storage unit 220 includes a main storage device and an auxiliary storage device. The main storage device may be realized by a semiconductor memory element such as a RAM, a ROM, or a flash memory. The auxiliary storage device may be realized by a hard disk, an SSD, an optical disk, or the like.

As shown in FIG. 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. The configuration of these units will be described below in order.

The door-to-door radio information storage unit 221 stores information about the door-to-door radio 100 registered in the communication device 200. It is advisable that the information about the door-to-door radio 100 stored in the door-to-door radio information storage unit 221 is synchronized as much as possible with the information about the door-to-door radio 100 stored in the door-to-door radio information storage unit 121 of the door-to-door radio 100 so that the same stored contents are maintained. For this reason, a detailed description of the information stored in the door-to-door radio information storage unit 221 will be omitted.

The mobile terminal information storage unit 222 stores information about the mobile terminals 300 registered in all of the individual door radios 100 registered in the communication device 200. Note that the information about the mobile terminals 300 stored in the mobile terminal information storage unit 222 is the same as the information about the mobile terminals 300 stored in the mobile terminal information storage unit 122 of the individual door radio 100. Therefore, a detailed description of the information stored in the mobile terminal information storage unit 222 will be omitted.

The evacuation terminal information storage unit 223 stores the evacuation terminal information transmitted from the door-to-door radio 100. Note that 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 description of the information stored in the evacuation terminal information storage unit 223 will be omitted.

The second control unit 230 is realized by a CPU, an MPU, or the like, executing various programs stored in the second storage unit 220 using the RAM as a working area. The second control unit 230 may also be realized by an integrated circuit such as an ASIC or an FPGA.

As shown in FIG. 6, the second control unit 230 includes a second information generation unit 231 and a second operation control unit 232. The second control unit 230 realizes the second information generation unit 231 and the second operation control unit 232 by reading and executing a program (software) from the second storage unit 220, and executes these processes. Note that the second control unit 230 may execute these processes using one CPU, or may include multiple CPUs and execute these processes in parallel using the multiple CPUs. This configuration will be explained step by step below.

The second information generating 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 generating unit 231 recognizes, among the mobile terminals 300 registered in the door-to-door radio 100, the mobile terminals 300 not included in the evacuation terminal information as non-evacuation terminals. The second information generating unit 231 reads out the "terminal specific information," "time information," "location information," and "movement information" of the door-to-door radio 100 connected to the mobile terminal 300 recognized as a non-evacuation terminal and the mobile terminal 300 from the door-to-door radio information storage unit 221 and the mobile terminal information storage unit 222, respectively, and generates these together as non-evacuation terminal information.

The second operation control unit 232 acquires information stored in the first memory unit 120 of the household radio 100 and controls it to store it in the second memory unit 220. Here, when the second operation control unit 232 acquires information stored in the household radio information memory unit 121, the mobile terminal information memory unit 122, and the evacuation terminal information memory unit 123, it stores this information in the household radio information memory unit 221, the mobile terminal information memory unit 222, and the evacuation terminal information memory unit 223 of the second memory unit 220, respectively. When it detects a communication interruption with the household radio 100, it issues a command to the second beacon transmitter 211 to transmit beacon information. The second operation control unit 232 acquires information that was acquired before communication with the household radio 100 was interrupted and stored in the first storage unit 120 of the household radio 100 and that is stored in the second storage unit 220 of the communication device 200, i.e., information stored in the household 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 an interruption of communication with the household radio 100, it acquires non-evacuation terminal information generated by the second information generation unit 231 based on information acquired immediately before communication was interrupted and stored in the second storage unit 220, and issues a command to the second beacon transmission unit 211 to transmit beacon information. The beacon signal transmitted by the second beacon transmission unit 211 includes the non-evacuation terminal information generated by the second information generation unit 231.
