As shown in FIG. 2, each dwelling unit 2 is provided with a residential fire alarm device 3, a transfer adapter 5, an outdoor alarm device 6, and a remote controller 4. As described above, the regional disaster prevention information system 1 includes the residential fire alarm device 3, the transfer adapter 5, the outdoor alarm device 6, the remote controller 4, the relay device 10, the master device 11, and the gateway 12. And a server 14. The resident of each dwelling unit 2 owns, for example, a portable information terminal 15, and a fixed telephone 16 is installed in each dwelling unit 2.

The residential fire alarm device (alarm device) 3 emits an alarm sound when it detects (detects) smoke or heat as an example of a fire phenomenon, and one or more is installed on the ceiling or the like of the dwelling unit 2. Further, the residential fire alarm device 3 has a transmitting/receiving unit (not shown) for transmitting/receiving a fire alarm signal, and when smoke is detected, the fire alarm signal is wirelessly transmitted. All of the residential fire alarm devices 3 installed in the same dwelling unit 2 emit an alarm sound when a fire alarm signal transmitted from any of the residential fire alarm devices 3 is received. The residential fire alarm device 3 may transmit a fire confirmation signal when the state in which a fire is detected continuously elapses for a predetermined time. In this case, the fire confirmation signal is transmitted to the relay device 10 via the transfer adapter 5 and the outdoor alarm device 6 which will be described later, similarly to the fire alarm signal.

One or more transfer adapters 5 are installed in the dwelling unit 2, and when the fire alarm signal or the like transmitted from the home fire alarm device 3 is received, the fire alarm signal or the like is transferred to the outdoor alarm device 6. The transfer adapter 5 and the outdoor alarm device 6 may be wirelessly transmitted/received, or may be connected by wire. Further, the transfer adapter 5 may be built in and integrated with the outdoor alarm device 6 described later. In this case, the outdoor alarm device 6 located outdoors receives wirelessly the fire alarm signal and the like transmitted from the residential fire alarm device 3.

The outdoor alarm device 6 (alarm device) is provided outside the dwelling unit 2 and stores a fire confirmation button (not shown), a false alarm confirmation button (not shown), and the ID of the dwelling unit 2 in which it is installed. A transmitter (not shown) for transmitting a wireless signal (not shown) is provided, and when a fire alarm signal or the like from the transfer adapter 5 is received, the fire alarm signal or the like is wirelessly transmitted together with its own ID. The fire confirmation button confirms that a fire is a fact when operated, and when the fire confirmation button is pressed, the outdoor alarm device 6 sends a fire confirmation signal to the relay device 10 together with its own ID. It is something to send.

In addition, when the outdoor alarm device 6 receives no fire confirmation signal for a predetermined time after receiving the fire alarm signal transmitted from the residential fire alarm device 3, and does not perform the false alarm confirmation operation described later, it is spontaneous. May be configured to send a fire confirmation signal to the repeater 10. The false alarm confirmation button confirms that the fire alarm is a false alarm when operated. When the false alarm is confirmed, the outdoor alarm device 6 transmits a false alarm confirmation signal to the relay device 10. The storage unit for storing the ID may be provided in the transfer adapter 5 so that the fire alarm signal and the like can be transmitted from the transfer adapter 5 to the outdoor alarm device 6 together with its own ID.

The remote controller 4 is owned by the resident of the dwelling unit 2 or fixed to an arbitrary place in the dwelling unit 2 and is operated by the resident by itself when a fire or an emergency occurs. The emergency state means, for example, a state in which the resident has become unwell. The remote controller 4 has a fire button 4a and an emergency button 4b, and also includes a transmitter (not shown) that transmits a wireless signal. As a method of using the remote controller 4, when a fire occurs, the owner who discovers the fire operates the fire button 4a, and when an emergency occurs, the owner who encounters an emergency situation can The button 4b is operated. The fire button 4a is for confirming that a fire is a fact when it is operated, and when the fire button 4a is continuously pressed for, for example, 3 seconds, the remote controller 4 causes the fire confirmation signal (corresponding to a fire notification signal). Is transmitted from the transmission unit to the relay device 10. Then, a fire alarm unit (not shown) provided in the remote controller 4 notifies the fire. The fire alarm unit includes, for example, a buzzer and an LED. When the fire button 4a is operated, the buzzer sounds and the LED flashes.
The signal transmitted by operating the fire button 4a may be the same signal as the fire alarm signal transmitted from the residential fire alarm device 3. In that case, the fire confirmation button of the outdoor alarm device 6 Press the button to confirm the fire.

Further, the emergency button 4b is for confirming that the emergency state is in an emergency state when operated, and when the emergency button 4b is pressed, the remote controller 4 transmits an emergency alarm signal from the transmission unit to the relay device 10. To do. Then, an emergency notification unit (not shown) provided in the remote controller 4 reports an emergency. The emergency notification unit includes, for example, a buzzer and an LED. When the emergency button 4b is operated, the buzzer sounds and the LED lights. Furthermore, when the fire button 4a and the emergency button 4b are pressed simultaneously while the fire alarm section or the emergency alarm section is informed, the fire alarm section or the emergency alarm section is restored. It The remote controller 4 includes a storage unit (not shown) for storing its own ID, and when transmitting a signal such as a fire confirmation signal or an emergency warning signal from the transmission unit, it must be transmitted together with its own ID. Then, the sender (the owner of the remote controller 4) can be specified. Further, a signal from the remote controller 4 may be received and relayed by the nearby outdoor alarm device 6. At this time, the place where the remote controller 4 is pressed can be specified in more detail by adding and transmitting the ID of the outdoor alarm device 6.

Signals such as a fire alarm signal, a fire confirmation signal, and an emergency alarm signal are transmitted to the server 14 via the relay device 10, the master device 11, the gateway 12, and the communication line 13. The server 14 analyzes the communication information acquired from the master device 11 and generates an e-mail based on the signal, the identification ID, and the stored information included in the communication information. Then, the server 14 causes the terminal server 14a, which will be described later, to send an e-mail (fire alarm signal) to the information terminal 15 of the resident who is the primary notification destination, who is a partner to inform that the residential fire alarm 3 has been activated. After that, when a fire is confirmed by the resident who has the information terminal 15 that receives the e-mail (fire alarm signal) and the fire confirmation button of the outdoor alarm device 6 is operated, a fire confirmation signal is transmitted to the server 14, and the server 14 The terminal server 14a is caused to send an e-mail (fire confirmation signal) to the resident at the secondary notification destination.

The relay device 10 is provided in a predetermined area R, receives a fire alarm signal from the home fire alarm device 3 transmitted from the outdoor alarm device 6, and transmits the fire alarm signal to the master device 11 of the management unit 2a. .. As shown in FIG. 8, the repeaters 10 are arranged at intervals of about 100 m (one per 50 m radius), each of which is given an identification ID, and when transmitting a signal to the master 11, It adds its own ID to the received signal and transmits it. This identification ID is stored in the server 14 described later in association with the ID and the installation location. Further, the relay device 10 receives the fire confirmation signal transmitted from the outdoor alarm device 6 and transmits it to the master device 11. Further, the relay device 10 receives the fire confirmation signal transmitted from the remote controller 4 and transmits it to the master device 11. Furthermore, the relay device 10 receives the emergency alarm signal transmitted from the remote controller 4 and transmits it to the master device 11. The repeater 10 is installed, for example, on an upper part of an outdoor pillar in the area R. In addition, when the outdoor alarm device 6 and the remote controller 4 are within a distance capable of transmitting and receiving to and from the base unit 11, signals may be exchanged without passing through the relay unit 10.
Further, the relay device 10 may be capable of relaying a signal transmitted/received from another relay device 10. In this case, since the relay 10 receiving the signal transmitted from the other relay 10 has the ID of the other relay 10 added to the signal, the relay 10 does not add its own ID to the received signal as it is. You may make it transmit. By doing so, even if the signal of the repeater 10 does not reach the master device 11 directly, the signal can reach the master device 11 by using a technique such as ad hoc communication.

Further, the relay machine 10 measures the electric field strength of the fire confirmation signal or the emergency warning signal received from the remote controller 4, and transmits the electric field strength to the master machine 11 together with the fire confirmation signal or the emergency warning signal. Here, the received electric field strength is based on the capability of the receiving antenna (not shown) included in the repeater 10, and an example thereof is shown in the first embodiment. For example, the electric field strength is measured within the range of 25 to 99 dbμV. If the electric field strength is less than 25 dbμV, radio waves may be destroyed, so measurement is not performed. Further, when the electric field strength exceeds 99 dbμV, the software exemplified in the first embodiment cannot measure the electric field strength. Therefore, it is not measured. However, if the software is changed, the electric field strength exceeding 99 dbμV can be measured. is there.

The main|base station 11 is provided in the management part 2a in which the connection environment to the communication line 13 is prepared in the area R, and receives the fire alarm signal, the fire confirmation signal, and the emergency alarm signal from the relay machine 10. Is. The base unit 11 is connected to the communication line 13 via the gateway 12. The base unit 11 also has a transfer contact 11a. The transfer contact 11a is a terminal that transfers a signal when it is closed, and the operating conditions for closing the transfer contact 11a can be appropriately changed by changing the software. In the first embodiment, the operation condition for closing the transfer contact 11a is that the master device 11 receives the fire confirmation signal or the emergency alarm signal from the relay device 10.

The voice device 17 is connected to the transfer contact 11a of the base unit 11, and is installed, for example, under the eaves of the management unit 2a. The audio device 17 is connected to the master device 11 by wire or wirelessly. One or more audio devices 17 are provided in one region R. The voice device 17 sounds an alarm when the transfer contact 11a of the base unit 11 is closed, and is, for example, an electronic siren having a sound pressure of 110 dB at a distance of 1 m. The audio device 17 automatically sounds a voice in response to a signal transmitted from the master device 11, but it is also possible to manually sound a voice.

When the emergency button 4b of the remote controller 4 is pressed outdoors, the emergency alarm signal transmitted from the remote controller 4 is received by the repeater 10 within the range of the emergency alarm signal. Therefore, when the master device 11 receives the emergency alarm signal from the relay device 10, the emergency button 4b of the remote controller 4 is pressed regardless of the position of the dwelling unit 2 of the person who has pressed the emergency button 4b of the remote controller 4. The audio device 17 installed at a position close to the sounding place sounds an alarm.

The gateway 12 performs protocol conversion on the fire alarm signal, the fire confirmation signal and the emergency alarm signal acquired by the base unit 11, and transmits the fire alarm signal, the fire confirmation signal and the emergency alarm signal to the server 14 via the communication line 13. Send. The gateway 12 may be built in the base unit 11 and integrated.

The server 14 has a terminal server 14a and a fixed telephone server 14b. Further, the server 14 has a storage unit 25 described later, and stores a plurality of tables such as a user table, a terminal information table, and a report destination table. When the server 14 receives the fire alarm signal, the fire confirmation signal, the false alarm confirmation signal, and the emergency alarm signal, the server 14 writes a sentence corresponding to each signal from the message table described later based on the information regarding the predetermined area R. Source information (name, etc.) of the signal is added to create a sentence of an electronic mail and a voice message, and the sentence is transmitted to the terminal server 14a and the fixed telephone server 14b together with the destination of the stored destination, Send an e-mail instruction and a telephone call instruction to each. The terminal server 14a sends an e-mail to the information terminal 15 owned by a target resident in the predetermined area R based on the mail sending instruction from the server 14. Here, the information terminal 15 is, for example, a mobile phone, a smart phone, or the like, and has a function of receiving an electronic mail. The terminal server 14a may be a cloud server. Further, the fire confirmation signal includes a signal transmitted from the automatic fire alarm facility (installed by the Fire Service Act) to the regional disaster prevention information system 1 by a fire input adapter (not shown).
Further, the server 14 associates the ID of the repeater 10 with the installation location (for example, latitude and longitude) in the storage unit 25 described later and stores it in, for example, a user table described later.

Based on the telephone call instruction from the server 14, the fixed telephone server 14b calls the fixed telephone 16 installed in the dwelling unit 2 via the network and reads the message transmitted from the server 14. Specifically, the fixed telephone server 14b is connected to the server 14 via a network or the like, and converts the text of the message transmitted from the server 14 into a voice message by a voice synthesizer. Then, the fixed telephone server 14b makes a call to the fixed telephone 16 installed in the predetermined dwell unit 2 designated by the server 14. The fixed telephone server 14b plays the converted voice message when the resident answers the telephone. The communication line 13 and the network may be the same network or different networks.

The terminal server 14a and the fixed telephone server 14b may be integrated with the server 14. The server 14a for terminals and the server 14b for fixed telephones may be located in different places from the server 14, in which case the server 14 and the server 14a for terminals and the server 14b for fixed telephones are connected via the communication line 13. It may be connected or may be connected via a different network.

The fixed line server 14b may call the fixed line telephone and read the message only when the fire confirmation signal is received. Further, the fixed line server 14b may call the fixed line and read the message only when the emergency alarm signal is received. As a result, if the fire alarm signal is a false alarm, it is possible to prevent the residents from feeling anxiety. This setting can be made, for example, in the message table described later.

Also, when the server 14 receives the fire alarm signal, the server 14 calls the fixed telephone server 14b only to the fixed telephone of the dwelling unit 2 extremely close to the dwelling unit 2 in which the residential fire alarm 3 is activated and reads the message. You may instruct. As a result, the evacuation guidance can be promoted to the residents whose primary purpose is evacuation guidance instead of mutual assistance. The resident whose primary purpose is evacuation guidance instead of mutual assistance is, for example, a resident who does not have the information terminal 15, and is, for example, an elderly person. Further, the server 14 has a range of dwelling units 2 to call when a fire confirmation signal or an emergency warning signal is received, and a range of dwelling units 2 to call when a fire warning signal is received, with respect to the fixed line server 14b. You may spread more. This allows a wide range of residents to be notified when a fire is established or an emergency situation is established.

It should be noted that the server 14 may determine that the fire has been confirmed when the fire confirmation signal or the false alarm confirmation signal has not been received for a predetermined time after receiving the fire alarm signal. By doing so, even if the fire confirmation operation is not performed for some reason during the fire, it can be treated as a fire.

FIG. 3 is a block diagram showing the server 14 according to the first embodiment of the present invention. As shown in FIG. 3, the server 14 has a storage unit 25, a calculation unit 20, and a transmission unit 24. The storage unit 25 stores a plurality of tables, and stores, for example, a user table, a terminal information table, a message table, and a report destination table. Here, each table stored in the storage unit 25 will be described with reference to FIGS. 4 to 7.

FIG. 4 is a diagram showing a user table according to the first embodiment of the present invention. As shown in FIG. 4, the user table includes the name or name of the installation user who installed the outdoor alarm device 6 or the remote controller 4, the email address of the installation user, the telephone number of the installation user, the address of the dwelling unit 2 of the installation user, The latitude and longitude of the dwelling unit 2 of the installation user are associated with each other. The server 14 can read the mail address, telephone number, address, etc. based on the installed user by referring to the user table.

FIG. 5 is a diagram showing a terminal information table according to Embodiment 1 of the present invention. As shown in FIG. 5, the terminal information table associates IDs (terminal numbers), terminal types, and installed users. The ID is, for example, a 4-digit number. The terminal type is, for example, the outdoor alarm device 6 or the remote controller 4. The server 14 can read the installed user based on the ID by referring to the terminal information table.

FIG. 6 is a diagram showing a message table according to the first embodiment of the present invention. As shown in FIG. 6, the message table associates signal types (alarm signals), notification radii, titles, electronic mail messages, and voice messages. The alarm signal is, for example, an alarm device (fire alarm device 3 for home) operation, a fire confirmation or an emergency notification. The signal when the alarm is activated is a fire alarm signal. The signal at the time of confirming the fire is the fire confirming signal. The signal at the time of issuing an emergency call is an emergency alarm signal. The subject is displayed as the subject of each message.

The reporting radius is a distance from the place (reporting source) where the warning signal is transmitted, and is calculated based on the latitude and longitude stored in the user table. In the case of the primary notification (fire alarm signal), the e-mail message and the voice message are changed, for example, when the notification radius is 7 m. That is, for a user who installs the dwelling unit 2 within a reporting radius of 7 m, it is easy to rush to the site because it is close to the origin of the fire alarm signal. Therefore, an e-mail message prompting confirmation of the presence or absence of an immediate fire is transmitted.

Further, in the first embodiment, a voice message prompting the user to confirm the presence or absence of an immediate fire is set for the user who installs the dwelling unit 2 within the reporting radius of 7 m. In the case of a fire report from the remote controller 4, the first signal is the fire confirmation signal, which corresponds to the secondary report (FIG. 6) described later. Therefore, the above-described operation of the primary report (FIG. 6) is for home use. This is the operation when a fire alarm 3 detects a fire. Also, the email message in the primary notification contains a confirmation link (fire confirmation operation URL) that confirms that the fire is a fact, and the resident who received the email must click the confirmation link. Will settle the fire.
When the signal from the fire button 4a of the remote controller 4 is a fire alarm signal, the same operation as in the case of the fire alarm signal from the residential fire alarm device 3 according to the first embodiment may be performed.

In the case of a secondary notification (fire confirmation signal), the notification radius is changed between the e-mail message and the voice message, for example, with the notification radii of 70 m and 250 m as boundaries. That is, in the case of a user who installs the dwelling unit 2 within a reporting radius of 70 m, since the fire confirmation signal is close to the originator of the fire, a message for e-mail is set which urges safety assurance and fire fighting.

If the reporting radius is more than 70 m and less than 250 m, it is a little far from the originator of the fire confirmation signal, so an e-mail message is set to encourage safety and to participate in fire fighting activities if possible. It On the other hand, when the reporting radius is more than 70 m and less than 250 m, the voice message is set to a message prompting evacuation. This is because the example of the case where the subject of the message notification on the fixed telephone 16 is an elderly person or the like is described here. In addition, in the first embodiment, the secondary notification is set to be sent to the residents of the dwelling unit 2 within a notification radius of 250 m, but it may be set to be sent to all dwelling units 2 in the area. In this case, the reporting radius may be a value that includes all the dwelling units 2, or the secondary reporting destination may be set to all the dwelling units 2 separately. Even in this case, as described above, the dwelling unit 2 close to the reporting source may be specified by the reporting radius, and the message for the dwelling unit 2 in the vicinity may be transmitted. In the first embodiment, the case where the voice message is not changed for each notification radius when the alarm device is activated is described. However, the voice message having the content according to the content of the e-mail message is provided for each notification radius. It may be set.

Further, when the emergency alarm signal is transmitted, an e-mail message prompting confirmation of the emergency state is set. In addition, when the emergency button 4b of the remote controller 4 is restored, an e-mail message for notifying that the emergency alarm is restored is set. In the first embodiment, even in the case of the emergency warning signal, the message is changed for each reporting radius.

FIG. 7 is a diagram showing a report destination table according to Embodiment 1 of the present invention. As shown in FIG. 7, the reporting destination table is a correspondence between the reporting source user and the reporting destination user. The issuing source user is an installed user who is the issuing source of the signal. The report-destination user is an installed user to whom an e-mail message or a voice message is transmitted regardless of the distance from the reporting source. The resident registered in the report destination user in FIG. 7 is, for example, a resident who has a special relationship with the reporting source user, such as a relative.

The server 14 accesses the map on the Web and identifies the alarm occurrence location (reporting source) based on the latitude and longitude registered in the user table. Further, the server 14 draws a virtual circle showing the range of the report radius centered on the alarm occurrence location on the map, and selects the dwelling unit 2 inside the circle from the latitude and longitude registered in the user table.

Next, the calculation means 20 and the transmission means 24 will be described with reference to FIG. As shown in FIG. 3, the calculating means 20 calculates the distance between the remote controller 4 and the repeater 10 based on the installation position of the repeater 10 and the electric field strength stored in the storage means 25. It is determined that the position of the remote controller 4 is closer to the repeater 10 as the electric field strength received by the repeater 10 is higher. Further, the calculating means 20 determines the remote controller 4 and the relay 10 from the electric field strength when the relay 10 receives the position of the remote controller 4 and the position of the relay 10 itself which receives the position of the remote controller 4. Is calculated. The electric field strength is preferably received by three or more repeaters 10.
For example, when three repeaters 10 receive a signal, it is estimated that the remote controller 4 exists inside a virtual circle centered on each repeater 10, and the position of the remote controller 4 is determined according to the received electric field strength. Is calculated. If the received electric field strength is high, the circles are small because they are close to each other, and if the received electric field strength is low, the circles are large because they are far from each other. The position of the remote controller 4 is accurately specified by comprehensively judging the three circles drawn around the three repeaters 10.
The electric field strength may be received by one repeater 10 or two repeaters 10. Even in this case, the position of the remote controller 4 can be narrowed down by adding the position of the relay 10 that does not receive the signal, the place where the relay 10 is not installed, etc. to the calculation conditions. When four or more repeaters 10 receive the signal, the electric field strength may be calculated based on the positions of all the received repeaters 10, or the electric field strength of the repeaters 10 that have received the signal may be calculated. The position of the remote controller 4 may be calculated based on the positions of the top three repeaters 10.

Here, the electric field strength varies depending on the location where the signal (radio wave) is transmitted, even if the electric field strength is the same, even though the electric field strength is the same. This is because the electric field strength is attenuated due to the presence of a building or the like that is an obstacle or a person between the remote controller 4 and the repeater 10. Therefore, the position of the remote controller 4 is not determined at one point even if the three repeaters 10 receive the signal, but is specified by a certain range divided for each probability distribution. Is good. In this case, the circle drawn by the electric field intensity received by the one repeater 10 described above becomes a figure (not necessarily a circle) considering the probability distribution. For example, even when the received electric field strength is the set lower limit value, it is calculated as a probability distribution that takes into consideration the case where the received electric field strength is shorter than the distance calculated from the lower limit value. After the probability distribution is calculated for each of the three repeaters 10, the position of the remote controller 4 is comprehensively determined as the probability distribution by comprehensively determining the calculated three probability distributions. At that time, the position of the remote controller 4 may be configured to be shown by a probability distribution on a map on the Web. In this case, the probability distribution of the position of the remote controller 4 is shown as contour lines on the map, for example. The display for each probability distribution is realized by, for example, color coding.
When an experiment was conducted on the electric field strength of the remote controller 4 received by the repeater 10, a predetermined electric field strength could be received even at a distance of 200 m in a space with good visibility, but a predetermined electric field strength was received in a space with obstacles. It was found that the distance that can be formed is about 50 to 100 m. In the first embodiment, the repeaters 10 are arranged at intervals of approximately 100 m (one per 50 m radius) (see FIG. 8 ). In this arrangement, in the region R, there is a place that is not included in a circle with a radius of 50 m centering on any of the repeaters 10, but a test for measuring the electric field strength is performed on site, and the signal of the remote controller 4 is As long as it is operated in the region R, it has been confirmed that it is received by at least one repeater 10.
As described above, the attenuation amount of the electric field strength may vary depending on the degree of congestion of the building. Therefore, after confirming the degree of congestion of the building in advance for each area where the regional disaster prevention information system 1 is used, the repeater 10 It is necessary to determine the installation interval and equipment specifications.

The transmission means 24 corresponds to an address near the remote controller 4 (an address located within a predetermined distance range of the remote controller 4) based on the position of the remote controller 4 calculated by the calculation means 20 and the address of the user table. The e-mail address is read, a message corresponding to the type of signal such as a fire alarm signal or an emergency alarm signal is read from the message table, and the message is transmitted to the e-mail address. Further, the transmitting unit 24 has a function of reading a message corresponding to the notification radius from the message table and transmitting a message corresponding to the notification radius to the mail address. Further, the transmitting means 24 reads the name of the resident corresponding to the ID of the remote controller 4 from the terminal information table, and sets this resident as the reporting source user. Then, the transmitting means 24 reads out the notification destination user corresponding to the reporting source user from the notification destination table, reads out the email address of the notification destination user from the user table, and sends a message to the email address (for example, in each alarm signal in FIG. 6). In contrast, it has the function of sending the same message as the smallest notification radius).
In addition, when the operated location of the remote controller 4 is different from the residence unit 2 of the owning resident, an email may be sent to all the residents in the region R regardless of the reporting radius. Good.

The message to be created is, for example, when an emergency report was issued to a resident within a radius of 70 meters, "[The reporter] made an emergency report. Please check it immediately if you are nearby. Location: [Occurrence location] ([Occurrence town name]) [Occurrence location URL] To perform "recovery operation" from an emergency, click the following. [Emergency recovery operation URL]”. (Selecting these URLs on the information terminal 15 causes a map of the place of occurrence and an operation screen to be displayed on the screen of the information terminal 15.) Here, the [reporter] is the owner of the remote controller 4, The “occurrence place” is the calculated position of the remote controller 4. In the first embodiment, an address is a concept that includes map information such as a location URL.

According to the first embodiment, the position of the remote controller 4 is calculated based on the installation position of the repeater 10 and the electric field strength. From this, the position of the remote controller 4 is specified. Therefore, the whereabouts of the resident who owns the remote controller 4 can be recognized. For example, even if the resident who owns the remote controller 4 has a fire or a bad physical condition at the place where he/she is going, he/she can recognize the whereabouts of the resident who is going out. At that time, the position of the remote controller 4 is transmitted to the resident by electronic mail. Therefore, a resident in the vicinity can rush to the location where the remote controller 4 exists. Furthermore, since the content of the e-mail message is changed for each reporting radius, a plurality of residents who have received the e-mail can work separately. Therefore, the work can be performed quickly, and waste can be eliminated. Furthermore, if the resident to be notified is designated, an electronic mail can be sent to the designated resident. As described above, since the resident designated as the report destination has a special relationship with the owner of the remote controller 4, for example, the illness of the resident who has been the source of the notification can be immediately confirmed, and quick response is possible. .. Further, when the position of the remote controller 4 is configured so as to be indicated by the probability distribution on the map on the Web, the location where the remote controller 4 exists can be efficiently searched.
