Determines the pulse as "1" and receives the communication signal transmitted from the fire detector 30 by the combination of the pulses.

Similar to the receiver communication unit 12, the sensor communication unit 32 fluctuates the line voltage of the wiring 70, combines pulses to transmit a communication signal to the fire receiver 10, and measures the line voltage. , Receives the communication signal transmitted from the fire receiver 10.
(Operation of fire alarm system 1)
Next, the operation of the fire alarm system 1 according to the first embodiment will be described with reference to FIG. In FIG. 2, the left side divided by the broken line shows the operation of the support device 100, the center shows the operation of the fire receiver 10, and the right side shows the operation of the fire detector 30.

The fire receiver 10, which is a fire receiving means, starts operation when power is supplied from a commercial power source (SJ01), and the receiver communication unit 12 outputs a voltage to the wiring 70 to supply power (SJ02). Power is supplied to the fire detector 30 which is a fire detection means.

When power is supplied to the fire detector 30, the sensor power supply unit 31, which is a power supply means, converts the voltage into the sensor operating voltage and supplies power to the sensor communication unit 32 and the fire detection unit 33 (SK03). .. When the power is supplied, the fire detection unit 33 starts the fire detection operation (SK04). Although not shown in detail in FIG. 2, when the fire detection operation is started, the fire detection unit 33 repeats the detection operation as to whether or not a fire has occurred at predetermined time intervals.

The receiver communication unit 12 identifies all the fire detectors 30 connected to the wiring 70 by the address and collects the status information such as whether the fire is detected, so that the fire detector 30 collects the status information. A signal is transmitted (SJ05).

When the sensor communication unit 32 receives the signal for collecting the state information (SK06), it is determined whether the fire detection unit 33 is detecting a fire by the fire detection operation (SK07). If a fire is being detected in step SK07, it is determined whether or not a notification during a fire, which will be described later, has been received from the fire receiver 10 (SK08). The sensor communication unit 32 transmits a fire signal as it is as status information when the notification of the occurrence of a fire has not been received in step SK08, and when the notification of the occurrence of a fire has been received, the detector communication unit 32 will be described later as the status information. The mobile terminal information of the mobile terminal 90 is added (SK09), and a fire signal is transmitted (SK10).

If the fire is not detected in step SK07, it is determined whether or not the fire receiver 10 has received the notification of the occurrence of a fire, which will be described later (SK11). The sensor communication unit 32 transmits a normal signal as it is as status information when the notification of the occurrence of a fire has not been received in step SK11, and when the notification of the occurrence of a fire has been received, the detector communication unit 32 will be described later as the status information. The mobile terminal information of the mobile terminal 90 is added (SK12), and a normal signal is transmitted (SK13). When the receiver communication unit 12 receives the status information from the fire detector 30 (SJ14), the fire determination unit 13 determines whether the status information includes the fire signal and whether it is the first reception of the fire signal. (SJ15). When the fire determination unit 13 determines in step SJ15 that the first fire signal is received, the display unit 14 displays the fire based on the information related to the address of the fire detector 30 that transmitted the fire signal stored in the terminal information unit 11. (SJ16), the receiver communication unit 12 transmits to the fire detector 30 that a fire is occurring (SJ17).

When the sensor communication unit 32 receives during a fire (SK18), the sensor power supply unit 31, which is a power supply means, supplies power to the position detection reception unit 51 and the support information transmission unit 52, which are position detection means (SK19). .. When the power is supplied, the position detection receiving unit 51 starts receiving the beacon signal from the mobile terminal 90 possessed by the resident in the vicinity of the fire detector 30 (SK20). Although not shown in detail in FIG. 2, when the position detection receiving unit 51 starts the receiving operation of the beacon signal, the detection of the beacon signal is repeated at predetermined time intervals, and the radio wave intensity of the detected beacon signal is measured. Further, when the fire detector 30 starts the operation of receiving the beacon signal, the fire detector 30 carries the mobile terminal unique number of the mobile terminal 90 receiving the beacon signal and the radio wave strength of the beacon signal as described in steps SK09 and SK12 described above. It is added to the status information as terminal information and transmitted to the fire receiver 10.

If the fire receiver 10 is not the first fire signal reception in step SJ15, the fire receiver 10 determines whether there is a fire detector 30 that has newly detected a fire or whether the position of the mobile terminal 90 has changed (SJ21). If there is no change, the process returns to step SJ05, and if there is a change, the external communication unit 16 externally uses the status information of the fire detector 30 as fire alarm information together with the address of the fire detector 30 that has transmitted the changed status information. It is transmitted to the support device 100 via the network NW (SJ22).

Here, since the state information first received after the fire detector 30 starts the beacon signal reception operation in step SK20 includes the mobile terminal information that has not been included up to that point, there is a change in step SJ21. Is judged. Therefore, the external communication unit 16 transmits the fire notification information to the support device 100.

When the support device 100 receives the fire notification information in the support device communication unit 101 (SS23), the mobile terminal determination unit 103 is based on the mobile terminal information included in the fire notification information and the address of the fire detector 30, and the terminal information unit 102. The location of the mobile terminal 90 is specified with reference to the terminal database of (SS24). The support information unit 104 analyzes the location of the fire occurrence location and the position of the mobile terminal 90 and creates support information suitable for the location where the fire detector 30 is installed so that the fire extinguishing activity and evacuation can be carried out smoothly. SS25).

Here, as an example of the support information, it will be described with reference to FIG. 3 assuming that the support information is map information. In FIG. 3, AD01 to AD07 indicate the fire detectors 30 installed at each location of the building, and the numbers 01 to 07 indicate the addresses assigned to the fire detectors 30. Further, T01 to T08 indicate the mobile terminal 90, and the numbers 01 to 08 indicate the mobile terminal unique number. Note that FIG. 3 shows a part of the building near the place where the fire occurred, and in reality, more fire detectors 30 are installed in a place other than the part of the building shown in FIG.

FIG. 3A is support information when the first fire signal is received in step SJ15, and the fire alarm information received in step SS23 includes only the information of the fire detector 30 of AD05 that transmitted the fire signal. Therefore, a flame mark indicating that a fire is occurring in the room where the fire detector 30 of AD05 is installed is added.

From FIG. 3A, where the support information unit 104 displayed only the fire information when the mobile terminal information was added to the status information in step SJ21 instead of receiving the fire signal for the first time in step SJ15. The support information is updated in FIG. 3 (b) with the addition of marks T01 to T08 indicating the position of the mobile terminal 90. At this time, when the plurality of fire detectors 30 receive the beacon signals of the same mobile terminal 90 (the mobile terminal unique number is the same), the fire that transmits the state information including the mobile terminal information of the strongest radio wave strength. A mark indicating the position of the mobile terminal 90 is added to the place of the mark of the sensor 30. For example, in FIG. 3, since there is no partition between the fire detectors 30 of AD06 and AD07, there is a possibility that both fire detectors 30 receive the beacon signal from the mobile terminal 90 existing between them. In that case, by using the information on the radio wave intensity, it is possible to determine which fire detector 30 the mobile terminal 90 is located near.

Further, the support information unit 104 changes the color or shape of the mark indicating the mobile terminal 90 possessed by the firefighters and the persons concerned based on the firefighter identification information and the persons concerned identification information stored in the support information unit 104. Create support information so that it can be identified by changing it. In FIG. 3B, it is shown that T04 is a firefighter and T05 is a related person.

In addition, in FIG. 3C, a fire spreads after a while, a new fire is detected by the fire detector 30 of AD07, and a person in the building who owns the mobile terminals 90 of T02, T03, T05, and T08. Is the support information in a state where has moved to the installation location of the fire detector 30 of AD06 for evacuation, and the fire brigade member possessing the mobile terminal 90 of T04 has moved to the installation location of the fire detector 30 of AD07.

When the support device communication unit 101 transmits the support information created by the support information unit 104 to the fire receiver 10 via the external network NW (SS26), and the fire receiver 10 receives the support information in the external communication unit 16 (SS26). SJ27), the receiver communication unit 12 transmits the support information by designating an address corresponding to the installation location of the fire detector 30 (SJ28). When the sensor communication unit 32 receives the support information (SK29), the support information transmission unit 52 transmits a support information signal to the mobile terminal 90 (SK30). The mobile terminal 90 that has received the support information signal can display the evacuation information based on the support information. The support information includes firefighter identification information and related party identification information, and the mobile terminal 90 having that information can also display information useful for fire extinguishing activities different from that of a general person's mobile terminal 90. .. When the mobile terminal 90 receives the support information signal from the plurality of fire detectors 30, the mobile terminal 90 has the largest information on the radio wave intensity included in the support information signal, that is, the nearest fire detector 30. It is also possible to display the support information received from.

For the support information, some patterns may be prepared and selected according to the position of the place where the fire occurred, or the support information signal may be used as the same information for all mobile terminals 90 as one radio field strength. May be sent only by. In addition, the support information may be in text only.

When the fire detector 30 receives a fire in step SK18, the support information transmitting unit 52 may transmit a beacon signal transmission command to force the mobile terminal 90 to transmit the beacon signal. ..

The fire receiver 10 transmits the fire alarm information to the support device 100 without determining whether the state information collected from the fire detector 30 in step SJ21 has changed, and the support device 100 transmits the fire alarm. It may be determined whether the information has changed and the support information may be updated.

Instead of transmitting the support information from the support device 100 to the mobile terminal 90 via the fire receiver 10 and the fire detector 30 as in steps SJ27 to SK30, the support device 100 passes through the external network NW. The information unique to the mobile terminal may be specified and directly transmitted to the mobile terminal 90.

In addition, the support information may be displayed at the fire department or an external disaster prevention center through the external network NW.

Further, the fire detector 30 supplies power to the position detection receiving unit 51 from the beginning when the power is received from the fire receiver 10, and acquires the position information of the resident even when no fire has occurred. You may.

Further, the support information unit 104 stores a person's name, telephone number, etc. in association with the mobile terminal unique number, and displays the name, telephone number, etc. in place of a symbol such as T01 in FIG. 3, or the mobile terminal 90. The name, telephone number, etc. may be displayed when the mark is touched. Further, information may be acquired from an external database or the like based on the mobile terminal unique number through an internet line or the like, and a person's name or the like may be displayed.

Further, when the beacon signal from the mobile terminal 90 includes an identification code for distinguishing from general people such as firefighters and people involved in the building, the support information unit 104 registers it in the firefighter identification information and the person concerned identification information. You may try to do it.

Further, the position detection receiving unit 51 receives a beacon signal from the mobile terminal 90 including only information indicating that the mobile terminal is a mobile terminal common to all mobile terminals, and detects only the presence of the mobile terminal 90 in the vicinity. You may do so.

Further, as a beacon signal, a signal for activating the software stored in the fire detector 30 is transmitted, and the software activated by receiving the beacon signal transmits a communication start from the fire detector 30 to the mobile terminal 90. After the mobile terminal 90 and the fire detector 30 that have received the communication establish communication, the mobile terminal information and the like may be exchanged.

Further, as the mobile terminal information, a unique identifier such as a MAC address may be transmitted, and the support device 100 may specify the position of the mobile terminal based on a database in which the identifier and the position information are associated with each other.

As described above, in this embodiment, the fire alarm system 1 can detect the position of the resident by detecting the mobile terminal 90 in the vicinity by the fire detector 30 which is a fire detection means, and thus the fire alarm system. It is not necessary to provide a communication line for connecting a sensor or the like for detecting the presence of a person separately from the communication line for connecting the fire detector 30, which is excellent in maintainability, workability and cost.

(Embodiment 3)
Embodiment 3 of the present invention will be described with reference to the drawings.
FIG. 5 is a schematic configuration diagram showing an example of the fire alarm system 3 according to the third embodiment of the present invention. In the fire alarm system 3, the wiring 70 in the fire alarm system 2 described in the second embodiment is changed from a pair of wires to three wires. In the third embodiment, the same reference numerals are given to the configurations common to the second embodiment, and the description thereof will be omitted.

The wiring 70A has a ground wire 71, a positive wire 72A, and a communication line 73.

The fire receiver 10A, which is a fire receiving means, includes a terminal information unit 11, a receiver communication unit 12A, a fire determination unit 13, a display unit 14, a battery 15, and an external communication unit 16.

The receiver communication unit 12A supplies 24V power to the plus line 72A and the communication line 73 with reference to the ground line 71. Then, the receiver communication unit 12A drops the voltage of the communication line 73 to generate a pulse that lowers the line voltage between the ground line 71 and the communication line 73 to 15 V or less for a predetermined time, and uses the fire detection means. A communication signal is transmitted to a fire detector 30B and a position detection terminal 50.

The sensor power supply unit 31 receives power from the fire receiver 10 via the ground wire 71 and the positive wire 72A of the wiring 70A, and converts the voltage into a sensor operating voltage (for example, 10V) which is a predetermined voltage. And supplies to each part of the fire detector 30B.

The same applies to the position detection communication unit 54, which is the position detection information transmission means.

That is, in the fire alarm system 3, the wiring 70A is set to 3 wires, the power for operating the fire detector 30 and the position detection terminal 50 is supplied by the plus wire 72A, and the fire receiver 10, the fire detector 30, and the position detection are supplied. The communication with the terminal 50 is performed by the communication line 73, and the power supply and the communication line are separated.

Here, the voltage drop that occurs in general wiring will be described. When a device is connected to the wiring, the wiring has a wiring resistance, so that a voltage drop of "current consumption of the device" x "wiring resistance" occurs in the wiring. Therefore, the voltage of "voltage of the supply source"-"voltage drop" is supplied to the device as a power source. When the current consumption of the device is constant, the wiring resistance increases as the wiring becomes longer, and the voltage supplied to the device decreases. If the length of the wiring does not change, increasing the number of connected devices will increase the current consumption of the devices and reduce the voltage supplied to the devices.

In the fire alarm system 2, the wiring 70 consisting of a pair of ground wire 71 and plus wire 72 supplies power to the fire detector 30B and the position detection terminal 50 and communicates with each other, but the voltage drops due to the wiring 70. When the voltage becomes large, the voltage supplied to the fire detector 30B and the position detection terminal 50 becomes equal to or less than the voltage for discriminating between "0" and "1" of the pulse, and communication becomes impossible.

On the other hand, in the fire alarm system 3, since the wiring 70A is set to 3 wires, even if a voltage drop occurs in the positive wire 72A that supplies power for operating the fire detector 30B and the position detection terminal 50, the communication line 73 Since no voltage drop occurs, the wiring distance can be extended or the number of connections of the fire detector 30B and the position detection terminal 50 can be increased as compared with the paired wire wiring 70.

The wiring 70 of the first embodiment may be the wiring 70A of three wires, and the same effect can be obtained.
(Embodiment 4)
Embodiment 4 of the present invention will be described with reference to the drawings.
FIG. 6 is a schematic configuration diagram showing an example of the fire alarm system 4 according to the fourth embodiment of the present invention. In the fire alarm system 4, the wiring 70 composed of a pair of paired wires in the fire alarm system 2 described in the second embodiment is replaced with the wiring 70B composed of two pairs of wires, and the fire detector 30B as a fire detecting means and the position detection. The terminal 50 is connected to another pair of wires. In the fourth embodiment, the same reference numerals are given to the configurations common to the second embodiment, and the description thereof will be omitted.

The wiring 70 has a first pair wire consisting of a ground wire 71 and a plus wire 72, and a second pair wire consisting of a ground wire 71B and a plus wire 72B.

The fire receiver 10B, which is a fire receiver means, includes a terminal information unit 11, a receiver communication unit 12B, a fire determination unit 13, a display unit 14, a battery 15, an external communication unit 16, and a position information communication unit 17.

The receiver communication unit 12B supplies power to the fire detector 30B and communicates with the fire detector 30B via the ground wire 71 and the plus wire 72 of the wiring 70.

The position information communication unit 17 supplies power to the position detection terminal 50 and communicates with the position detection terminal 50 via the ground line 71B and the plus line 72B of the wiring 70.
(Operation of fire alarm system 4)
The operation of the fire notification system 4 according to the fourth embodiment positions the power supply and communication to the position detection terminal 50 among the operations performed by the receiver communication unit 12 of the fire notification system 2 of the second embodiment. It is the same as the fire alarm system 2 except that the information and communication unit 17 performs the operation.

The position information communication unit 17 may supply power to the ground line 71B and the plus line 72B of the wiring 70B only during a fire to communicate with the position detection terminal 50.

As described above, in the fire alarm system 4, the receiver communication unit 12B communicates with the fire detector 30B, and the position information communication unit 17 communicates with the position detection information terminal 50. Therefore, a new fire and a mobile terminal are used. Since the 90 positions can be collected separately, information can be collected quickly.

The same effect can be obtained by using the ground wires 71 and 71B of the wiring 70B as one common ground wire 71C as shown in FIG. 7.

Further, the first pair wire and the second pair wire of the wiring 70B may be used as separate wiring.
(Embodiment 5)
Embodiment 5 of the present invention will be described with reference to the drawings.
FIG. 8 is a schematic configuration diagram showing an example of the fire alarm system 5 according to the fifth embodiment of the present invention. In the first embodiment, the fire alarm system that receives the beacon signal from the mobile terminal 90 has been described, but the fire alarm system 5 of the fifth embodiment is configured to transmit the beacon signal from the fire detector 30C. It was done. In the fifth embodiment, the same reference numerals are given to the configurations common to the first embodiment, and the description thereof will be omitted.

The fire detector 30C, which is a fire detection means, includes a detector power supply unit 31, a detector communication unit 32, a fire detection unit 33, a support information transmission unit 52, and an installation information transmission unit 55, which is an installation position information transmission unit. To prepare for.

The installation information transmission unit 55 transmits a beacon signal including the address of the fire detector 30C as installation position information. The installation position information may be information indicating the position of the fire detector 30C such as the installation floor and the installation coordinates of the fire detector 30C.

The support device 100C, which is a support means, includes a support device communication unit 101C, a terminal information unit 102, a mobile terminal determination unit 103C, and a support information unit 104.

The support device communication unit 101C receives information transmitted from the fire receiver 10 and the mobile terminal 90 via the external network NW, communicates with the fire receiver 10 and the mobile terminal 90, and exchanges information.

Based on the information received from the mobile terminal 90 by the support device communication unit 101C, the mobile terminal determination unit 103C, which is the mobile terminal determination means, has detected the beacon signal from which fire detector 30C by the mobile terminal 90 that has emitted the information. Is determined.
(Operation of fire alarm system 5)
Next, the operation of the fire alarm system 5 according to the fifth embodiment will be described with reference to FIG. In FIG. 9, the left side divided by the broken line shows the operation of the support device 100C, the center shows the operation of the fire receiver 10 which is the fire receiving means, and the right side shows the operation of the fire detector 30C which is the fire detecting means.

The fire receiver 10 starts operation when power is supplied (SJ01). Hereinafter, the operation up to step SK18 is almost the same as the operation of the fire alarm system 1 shown in FIG. 2, and therefore the description thereof will be omitted. The difference is that the fire notification system 5 does not receive the beacon signal including the mobile terminal unique number from the mobile terminal 90, so that it has been received during the fire by the fire detector 30 in FIG. 2 (SK08 and SK11). In this case, the operation of adding the information of the mobile terminal 90 to the state information (SK09 and SK12) is not performed. Therefore, in steps SK10 and SK13, which are transmissions of state information, the state information does not include the information of the mobile terminal 90.

When the sensor communication unit 32 receives the fact that a fire is occurring (SK18), the sensor power supply unit 31 supplies power to the installation information transmission unit 55 and the support information transmission unit 52 (SK50). When power is supplied, the installation information transmission unit 55 transmits a beacon signal including an address stored in the sensor communication unit 32. The beacon signal is transmitted by short-range wireless communication such as Bluetooth (registered trademark) or ZigBee (registered trademark) (SK51). When the mobile terminal 90 receives the beacon signal, the mobile terminal 90 transmits the mobile terminal information including the address included in the beacon signal and the mobile terminal unique number to the support device 100C via the external network NW. The support device communication unit 101C of the support device 100C receives the mobile terminal information via the external network NW (SS52). The mobile terminal determination unit 103C identifies the position of the mobile terminal 90 by referring to the terminal database of the terminal information unit 102 based on the mobile terminal unique number included in the received mobile terminal information and the address of the fire detector 30C (SS53). ).

If the fire receiver 10 is not the first fire signal reception in step SJ15, the fire receiver 10 determines whether there is a fire detector 30C that has newly detected a fire (SJ54), and if there is a change, the changed state information is displayed. Along with the transmitted address of the fire detector 30C, the status information of the fire detector 30C is transmitted as fire alarm information to the support device 100C by the external communication unit 16 via the external network NW (SJ55). The support device 100C receives fire notification information at the support device communication unit 101C (SS56). If there is no change in step SJ54, the process proceeds to step SS57.

The support information unit 104 determines whether there is any change in the received mobile terminal information and fire alarm information (SS57), and if there is no change, returns to step SJ05 without doing anything, and if there is a change, fire extinguishing activity or evacuation. Analyzes the location of the fire and the location of the mobile terminal 90 to create support information suitable for the location where the fire detector 30C is installed (SS25). Since the fire alarm system 5 operates in the same manner as the fire alarm system 1 from SS26 to SK30, the description thereof will be omitted. Further, since the support information can be the same as that of the first embodiment, the description thereof will be omitted.

As described above, since the fire alarm system 5 transmits a beacon signal indicating each of the fire detectors 30C, the position of the resident can be grasped based on the mobile terminal information from the mobile terminal 90, and thus the fire detector. It is not necessary to provide a communication line for connecting a sensor that detects the presence of a person separately from the 30C, and it is excellent in maintainability, workability and cost.

The support information may be displayed on an external device such as a fire station or an external disaster prevention center through the external network NW.

Further, the support device 100C may be provided with a display unit to display the support information. Further, the information stored in the support information unit 104 may be transmitted to an external device. Further, the support information created by the support information unit 104 is not transmitted to the mobile terminal 90 via the fire receiver 10 and the fire detector 30C as in steps SJ27 to SK30, but is transmitted from the support device 100C to the external network. The information unique to the mobile terminal may be specified and directly transmitted to the mobile terminal 90 via the NW.

Further, as a beacon signal, a signal for activating the software stored in the mobile terminal 90 is transmitted, and the software activated by receiving the beacon signal transmits a communication start from the mobile terminal 90 to the fire detector 30C. The fire detector 30C and the mobile terminal 90 may exchange the installation position information and the fire notification information after establishing the communication.

Further, a unique identifier such as a MAC address may be transmitted as the installation position information, and the position of the mobile terminal may be specified by the support device 100 based on a database in which the identifier and the position information are associated with each other.

Further, in the fire alarm system 5, like the fire alarm system 2, the support information transmission unit 52 and the installation information transmission unit 55 may be made independent from the fire detector 30C as position detection terminals, and the fire alarm systems 3 and 4 may be independent of each other. As described above, the wiring 70 may be a three-wire system or a pair of two wires.
