Description

The present invention relates to a fire alarm system, and more particularly to a fire alarm system with a P-type receiver.

In fire alarm systems installed in facilities such as buildings, when one of the multiple fire sensors installed detects a fire, the fire receiver issues a fire alarm, etc. configured to do so.
When a fire alarm is issued by a fire receiver, a fire prevention manager, a security guard, or the like usually rushes to the site to check whether the alarm is false or not, and takes measures such as initial fire extinguishing, notification, and evacuation.

There are various methods for connecting a plurality of fire detectors and fire receivers. For example, as shown in FIG. , these fire detectors 100 are connected to the lines 101 arranged in the security areas R1 to R4, respectively, and these lines 101 are connected to the fire receivers 102. FIG.
In the example shown in FIG. 8, caution areas R1 to R4 are set on the 1st to 4th floors of the facility, respectively, and six fire detectors 100 are installed in each caution areas R1 to R4. case is shown.

In this case, if the fire receiver 102 is, for example, an R-type receiver, the fire sensor that detected the fire transmits the fire detection signal and the specific information of the fire sensor to the fire receiver 102 .
Therefore, the information of the fire detector 100 that detected the fire is displayed on the fire receiver 102, so that the fire prevention manager or the like sees the display on the fire receiver 102 and selects the fire detector 100 that detected the fire. It can be easily identified, and a quick response can be made by rushing to the site where the fire detector 100 is installed.

Further, for example, in Patent Document 1, when a fire receiver 102 receives unique information about a fire sensor 100 that has detected a fire, a server associates it with map information, and a headquarters terminal, a fire prevention manager, or the like carries it. There is disclosed a technique for transmitting to a mobile terminal or the like and pinpointing the installation position of the fire detector 100 that has detected a fire on a map screen displayed on the headquarters terminal or the mobile terminal (in this case, The installation position of the fire sensor 100 is represented by, for example, an x mark on the map screen.).
In this case, by looking at the map screen displayed on the mobile terminal, the fire prevention manager can pinpoint the installation location of the fire detector that detected the fire. appropriate measures can be taken.

On the other hand, if the fire receiver 102 is, for example, a P-type receiver, as illustrated in FIG. there is
Then, when the fire detector 100 detects a fire, the fire receiver 102 issues a fire alarm from the speaker 102A and opens the area window W3 corresponding to the caution zone R3 where the fire detector 100 that detected the fire is installed. It is configured to notify that a fire has been detected by the fire detector 100 in the caution zone R3 by lighting it or the like.

JP 2018-106693 A

However, when the fire receiver 102 is a P-type receiver, the fire detection signal is transmitted from the fire sensor that detected the fire, but the specific information for specifying the fire sensor is not transmitted.
Therefore, as exemplified in FIG. 9, in the fire receiver 102, only the district window W3 corresponding to the caution zone R3 in which the fire detector 100 that has detected the fire is installed is lit. It is not displayed which fire detector 100 in has detected the fire.

Therefore, the fire prevention manager cannot pinpoint which fire detector 100 in the restricted area R3 has detected the fire, so he rushes to the restricted area R3 (the third floor of the facility in the example of FIG. 8). After that, it is necessary to thoroughly search the caution zone R3 to confirm whether or not there is a fire, and it takes time to check the site.
Therefore, it sometimes takes time to confirm whether or not it is a false alarm, and to take measures such as initial fire extinguishing, reporting, and evacuation.

The present invention has been made in view of the above problems, and is a fire alarm system capable of pinpointing a fire detector that has detected a fire even when the fire receiver is a P-type receiver. intended to provide

Also, during maintenance inspections, if the location of the fire detector that detected a simulated fire during maintenance inspections is displayed on the information terminal possessed by the disaster prevention manager or security guard, etc. However, during maintenance and inspections, the location of the fire detector that detected the simulated fire can be prevented from being displayed on the information terminal possessed by the disaster prevention manager. It is possible to reliably prevent such a situation from occurring.
Further, when the server receives the identification information of the information terminal for maintenance and inspection and the identification information of the transmitting/receiving device, the server is configured to determine an inspection area in which maintenance and inspection work is being performed based on the identification information of the transmitting/receiving device. Therefore, by using the fact that each transmitter/receiver automatically reads the identification information of the information terminal for maintenance inspection carried by the maintenance inspection worker, the server can accurately determine the inspection area where the maintenance inspection work is being performed. can be recognized.

Further, desirably, the transmitting/receiving device has a first communication unit capable of receiving the unique information transmitted from the transmitting device, and a second communication unit capable of transmitting the unique information to the server. configured as
Thereby, the transmitting/receiving device can accurately receive the unique information transmitted from the transmitting device by the first communication unit and accurately transmit the received unique information from the second communication unit to the server.

Further, preferably, the transmitting/receiving device is configured with an IoT gateway.
As a result, there is no need to attach a new wireless module to the transmitting/receiving device, and a single transmitting device can receive unique information from a plurality of transmitting devices. In addition, it becomes possible to connect various other IoT devices to the communication network, and if an IoT gateway is installed in the facility, it can be used as a transmitting/receiving device.

Further, desirably, the server stores map information of the warning area, and the location information and the map information of the warning area to which the fire sensor corresponding to the unique information belongs are stored in the information. configured to send to a terminal.
As a result, fire prevention managers and security guards can see the map of the restricted area displayed on the display screen of the information terminal and the position of the fire detector on the map, and determine which fire detector in which restricted area is on fire. is detected easily and clearly.

Also, preferably, the P-type receiver is configured to transmit fire information to the server via a communication device when the fire detector detects a fire.
As a result, the server can transmit position information to the information terminal using the fire information transmitted from the P-type receiver via the communication device as one trigger.

Further, desirably, when the location of the fire sensor determined based on the unique information of the fire sensor transmitted from the transmitting/receiving device is outside the inspection area, the server performs the maintenance inspection. information of the position in the security zone of the fire detector corresponding to the unique information to the information terminal, including an information terminal for the fire detector.
As a result, if a fire breaks out in a place other than the inspection area where maintenance and inspection work is being performed and the fire detector is activated, information terminals for maintenance and inspection, disaster prevention managers, security guards, etc. The position of the fire detector that detected the fire is displayed on the . Therefore, even during maintenance and inspection work, if a fire actually breaks out, the fire prevention manager, etc. will be able to reliably recognize the possibility of a fire actually breaking out based on the display on the information terminal. , you can rush to the location and take measures such as initial fire extinguishing, reporting, and evacuation. Moreover, in the case of false alarm, it can be confirmed that it is false alarm.

An embodiment of a fire alarm system according to the present invention will be described in detail below.
In the following also, caution areas R are set on the 1st to 4th floors of the facility (hereinafter referred to as caution areas R1 to R4), and six fire detectors 2 are installed in each caution areas R1 to R4. A case where they are installed one by one will be described as an example. However, the present invention is not limited to this case, and for example, it is possible to set the caution zone R in a narrower range than for each floor. That is, it is possible to set the caution area R, for example, for each room on each floor, or for the center, east side, or west side of each floor.

[Configuration of fire alarm system 1]
FIG. 1 is a diagram showing the configuration of a fire alarm system according to this embodiment. Also in the fire alarm system 1 according to this embodiment, a P-type receiver is used as a fire alarm receiver, like the fire alarm system shown in FIG.
Also in this embodiment, the fire alarm system 1 includes a single or a plurality of fire detectors 2 connected to the lines 3 arranged for each warning area R, and the lines 3 of the respective warning areas R. and a P-type receiver 4 . Note that the P-type receiver 4 may be simply referred to as the receiver 4 hereinafter.

The fire sensor 2 transmits a fire detection signal A to the receiver 4 via the line 3 when detecting smoke, heat, or the like. At that time, in this embodiment, the fire sensor 2 does not transmit unique information about itself even if it detects smoke, heat, or the like.
In addition, the line 3 transmits to the receiver 4 the fire detection signal A emitted by the fire detector 2 that has detected a fire as described above, and also supplies electric power to each fire detector 2. there is

The receiver 4 is the same as the P-type receiver used in the fire alarm system shown in FIGS. When A is transmitted, based on the line 3 or the like from which the fire detection signal A is transmitted, the warning area R (for example, the warning area R3) to which the fire detector 2 belongs is determined, and the fire alarm is issued or determined. A zone window W (for example, a zone window W3) corresponding to the warning zone R is turned on to notify that a fire has been detected by the fire detector 2 in the warning zone R3.

Further, in this embodiment, the receiver 4 is connected to the server 8 described later via the communication device 5 and the communication network N, and when receiving the fire detection signal A from the fire sensor 2 as described above, the server 8, the fire information B and the information of the caution area R to which the fire detector 2 that detected the fire belongs (hereinafter referred to as the caution area information C) are transmitted.
This point will be explained later.

On the other hand, in the present embodiment, each fire sensor 2 is provided with a transmitting device 6 that transmits unique information E of the fire sensor 2 when the fire sensor 2 detects a fire.
It should be noted that the transmitting device 6 can be configured to be attached to the fire sensor 2, or can be configured integrally with the fire sensor 2, or the transmitting device 6 can be attached to the fire sensor. It is also possible to configure so as to be installed in the vicinity of 2 or the like.
Alternatively, the transmitting device 6 can specify which fire sensor 2 has detected the fire and transmit the specific information E, and the transmitted unique information E can be received by the transmitting/receiving device 7, which will be described later. The transmitting device 6 does not necessarily have to be in the vicinity of the fire sensor 2 or the like.

Specifically, the transmitting device 6 includes a control section 61, a unique information storage section 62, and a communication section 63, as shown in FIG.
The control unit 61 receives a fire detection signal A sent to the receiver 4 by the fire sensor 2 that has detected a fire, and detects changes in current, voltage, etc. that occur in the fire sensor 2 when a fire is detected. For example, when the fire sensor 2 detects that the fire has been detected, the unique information E of the fire sensor 2 is read out from the unique information storage unit 62 constituted by a memory or the like.

In this case, as the specific information E, for example, the serial number, initial value, address value, etc. of the fire sensor 2 can be used.
Then, the control unit 61 transmits the fire information D and the read specific information E of the fire sensor 2 from the communication unit 63 by short-range communication such as Bluetooth (registered trademark) Low Energy (BLE). In this embodiment, the transmission device 6 thus transmits the fire information D and the specific information E of the fire sensor 2 when the fire sensor 2 detects a fire.

In this embodiment, at least one transmitting/receiving device 7 is arranged for each of the restricted areas R1 to R4. Then, the transmitting/receiving device 7 can receive the fire information D transmitted from the transmitting device 6 and the unique information E of the fire sensor 2 and transmit them to the server 8 described later via the communication network N. ing.
The number and positions of the transmitting/receiving devices 7 are determined so that the specific information E of the fire sensor 2 and the like transmitted from all the transmitting devices 6 can be received by any one of the transmitting/receiving devices 7 . In this case, it is possible to configure the transmitter/receiver 7 by the same number as the fire sensors 2, that is, to provide one transmitter/receiver 7 for each fire sensor 2. It is possible to reduce the cost of constructing the fire alarm system 1 by configuring it so that it can receive the unique information E and the like from the fire detector 2 (transmitting device 6) respectively, which is preferable.

As shown in FIG. 2, the transmitting/receiving device 7 includes a first communication unit 71 capable of receiving the fire information D transmitted from the transmitting device 6 and the unique information E of the fire sensor 2, and the received fire information D. and a second communication unit 72 capable of transmitting the unique information E to the server 8 via the communication network N.
Then, when the transmitting device 6 transmits the fire information D and the specific information E of the fire sensor 2 that detected the fire as described above, the transmitting/receiving device 7 receives them at the first communication unit 71, The received fire information D and unique information E are converted into a protocol for network communication, and the fire information D and unique information E are transmitted from the second communication unit 72 to the server 8 via the communication network N. It's becoming

The transmitting/receiving device 7 can be composed of, for example, an IoT gateway. In order to connect various IoT devices to the communication network N, the IoT gateway usually has a built-in wireless module, so there is no need to install a new wireless module. Unique information E and the like can be received respectively.
Further, if an IoT gateway is used as the transmission/reception device 7, it becomes possible to connect various other IoT devices to the communication network N. can be used as

The server 8 (see FIG. 1) stores a correspondence table (not shown) that associates the specific information E of each fire sensor 2 with the position F of the fire sensor 2 in the caution areas R1 to R4.
In this embodiment, the server 8 receives the fire information D from the transmitter/receiver 7 and the specific information E of the fire sensor 2 that detected the fire, receives the fire information B from the receiver 4, and receives the fire information B from the transmitter/receiver 7. When the fire information D is obtained, the process for transmitting the information to the information terminal 9 is started.

That is, when the server 8 receives the fire information D and the unique information E of the fire detector 2 that has detected the fire from the transmitting/receiving device 7 as described above, the server 8 stores the transmitted unique information E based on the correspondence table. The position F of the fire sensor 2 corresponding to .
In the following description, as shown in FIG. 1, the fire sensor 2 belonging to the caution area R3 detects a fire.

Then, when the server 8 determines the position F in the caution area R3 of the fire sensor 2 corresponding to the transmitted unique information E as described above, the server 8 transmits the information of the determined position F to the information terminal 9. It's like
In addition, in this embodiment, the server 8 also stores the information of the map G of each caution area R1 to R4, and together with the information of the position F, the fire detector 2 corresponding to the transmitted unique information E (that is, Information on the map G of the caution area R3 to which the fire detector 2) that has detected the fire belongs is also transmitted to the information terminal 9. FIG. In addition, the information on the position F and the information on the map G of the warning area R may be collectively referred to as the alarm location information H hereinafter.

In this embodiment, the information terminal 9 is a smart phone possessed by a fire prevention manager, security guard, or the like, and the server 8 transmits the alarm location information H to the information terminal 9 via the communication network N or the base station 10. It is designed to
The information terminal 9 may be a mobile phone, a tablet-type mobile terminal, or the like. In addition, in FIG. 1, the information terminal 9 is shown outside the restricted areas R1 to R4, but this is for the purpose of making the drawing easier to see. stomach.

Then, when the information terminal 9 receives the alarm location information H (the information of the position F and the information of the map G) from the server 8, for example, as shown in FIG. , the map G of the caution area R3 (in this case, the third floor of the facility) is displayed.
Then, based on the information on the position F, the position F of the fire sensor 2 that detected the fire is displayed in a predetermined color, and other fire sensors 2 on the map G ( (See ○ mark)).

When the information terminal 9 displays the position F of the fire sensor 2 that detected the fire on the display screen 91, the information terminal 9 displays the position F so that the fire prevention manager or the like can quickly notice that it has been displayed. At the same time, it is also possible to configure so as to generate sound, vibration, or the like to give notification.

In this embodiment, the display screen 91 of the information terminal 9 thus displays the map G of the caution area R3 to which the fire detector 2 that has detected the fire belongs, and the fire that detected the fire is displayed on the map G. Position F of sensor 2 is indicated.
With this configuration, a fire prevention manager, a security guard, or the like can see the map G of the caution area R displayed on the display screen 91 of the information terminal 9 and the display of the position F of the fire sensor 2 on the map G. Thus, it is possible to easily and clearly recognize which fire sensor 2 in which caution area R (in this case, caution area R3) has detected a fire.

Further, in this embodiment, the information terminal 9 displays the map G on the display screen 91, and indicates which caution zone R (in this case, the caution zone R3 (in FIG. 3, "East Building 3rd Floor"). )), a text display 92 indicating that the fire sensor 2 has been activated is also provided.
Therefore, a fire prevention manager, a security guard, etc., sees not only the map G but also the text display 92 to clearly and reliably identify which fire detector 2 in which alert area R (in this case, alert area R3) has detected a fire. can be recognized.

[Action]
Next, the action of the fire alarm system 1 according to this embodiment, that is, the flow of information, signals, etc. will be described in chronological order based on FIG.
When the fire sensor 2 detects a fire, it transmits a fire detection signal A to the receiver 4 (P-type receiver 4) via the line 3. FIG. When the receiver 4 receives the fire detection signal A from the fire detector 2, the receiver 4 issues a fire alarm or the like to notify that a fire has been detected, and also receives the fire information B and the fire detector 2 that detected the fire. It transmits to the server 8 via the communication device 5 the caution area information C that the caution area R to which it belongs is the caution area R3.
When the server 8 receives the fire information B and the warning area information C, it saves and holds them in the memory.

Further, when the fire sensor 2 detects a fire as described above, the transmission device 6 corresponding thereto transmits the fire information D and the unique information E of the fire sensor 2 . Then, when the transmitting/receiving device 7 receives them, the transmitting/receiving device 7 transmits the fire information D and the unique information E of the received fire sensor 2 to the server 8 via the communication network N. FIG. When the server 8 receives the fire information D and the specific information E of the fire sensor 2, it saves them in memory.
Then, when the fire information B from the receiver 4 and the fire information D from the transmitting/receiving device 7 are complete, the server 8 stores the transmitted unique information E based on the warning area information C and the stored correspondence table. A position F in the caution area R3 of the fire sensor 2 corresponding to is determined.

Then, when the server 8 determines the position F of the fire sensor 2 corresponding to the transmitted specific information (that is, the fire sensor 2 that detected the fire) in the caution zone R3, the determined position F information and the warning zone The information on the map G of R3, that is, the information on the location where the alarm is issued H is transmitted to the information terminal 9 possessed by the fire prevention manager, the security guard, or the like.
In this way, as shown in FIG. 3, the map G of the caution area R3 to which the fire detector 2 that detected the fire belongs is displayed on the display screen 91 of the information terminal 9, and the fire is detected on the map G. The position F of the fire sensor 2 is displayed.

Then, when the fire prevention manager, security guard, etc. responded at the site and completed the process and confirmed that the situation was safe, the receiver 4 was operated to restore, as shown in FIG. 4 transmits a restoration signal I to the server 8 via the fire detector 2 that detected the fire and the communication device 5, respectively.
When the fire sensor 2 that has detected the fire receives the restoration signal I, it returns to its original state (the state in which no fire is detected). Further, when the server 8 receives the recovery signal I, the series of processes started in response to the detection of fire by the fire sensor 2 ends.

[effect]
As described above, according to the fire alarm system 1 according to the present embodiment, even if the P-type receiver 4 does not receive the unique information from the fire sensor 2 that detected the fire, The transmitting device 6 transmits the unique information E and the like of the fire sensor 2 , and the unique information E and the like are transmitted to the server 8 via the transmitting/receiving device 7 .
Then, the server 8 calculates the position F of the fire sensor 2 in the caution zone R corresponding to the unique information E based on the correspondence table, and transmits it to the information terminal 9 .

Therefore, since the position F of the fire sensor 2 that detected the fire is pinpointed on the display screen 91 of the information terminal 9, the fire receiver is a P-type like the fire alarm system 1 according to the present embodiment. Even in the case of a receiver, a fire prevention manager, guard, etc. can pinpoint and accurately identify the fire detector 2 that detected the fire by looking at the display on the information terminal 9. .
Therefore, after rushing to the restricted area R3, the fire prevention manager searches the vicinity of the fire detector 2 that detected the fire, quickly confirms whether or not it is a false alarm, and responds to initial fire extinguishing, reporting, evacuation, etc. It is possible to promptly take measures, and it is possible to quickly check the site and take appropriate measures.

The fire alarm system 1 according to the present embodiment can be adopted when a new fire alarm system is introduced, such as when a new building is built, but an existing P-type system (P-type receiver It is also possible to apply it to a fire alarm system).
In this case, it is necessary to newly attach a transmitting device 6 to each existing fire sensor 2, arrange each transmitting/receiving device 7, or provide a server 8. It is possible to rebuild the fire alarm system at a lower cost than replacing with a type that transmits unique information by itself or replacing the fire receiver with an R-type receiver (that is, replacing the entire fire alarm system with an R-type system). .

Also, in the conventional P-type system (see FIGS. 8 and 9), when the fire detector 100 detects a fire and the receiver 102 issues a fire alarm, a fire prevention manager, security guard, or the like is at the receiver 102. It was not possible to recognize in which caution area R a fire was detected unless the worker went to the area and checked the illuminated district window W.
However, in the fire alarm system 1 according to the present embodiment, the information terminal 9 carried by the fire prevention manager, guard, etc. displays the position F in the caution area R of the fire detector 2 that has detected the fire. A manager or the like can go straight to the caution zone R without going to the receiver 4.例文帳に追加Therefore, in the fire alarm system 1 according to the present embodiment, in this respect as well, the fire prevention manager or the like can rush to the caution area R more quickly to check the site and take appropriate measures more quickly. .

Furthermore, according to the fire alarm system 1 according to the present embodiment, information such as the position F of the fire detector 2 that detected the fire and information on the caution area R is displayed on each information terminal 9 possessed by the fire prevention manager, guard, etc. can be displayed.
Therefore, it becomes possible for a plurality of fire prevention managers and the like to perform fire extinguishing work, etc. while checking each other by looking at the display on the information terminal 9, so that fire extinguishing work, etc. can be performed safely and reliably.

By the way, in the fire alarm system 1 according to the present embodiment, as described above, the server 8 detects the location where the fire was detected based on the warning area information C received from the receiver 4. It is configured to be recognized as the caution area R to which the device 2 belongs (the caution area R3 in the above example).
However, for example, the receivable range (hereinafter referred to as the warning area r) of the transmitting/receiving device 7 that receives the fire information D and the unique information E of the fire sensor 2 from the transmitting device 6 corresponding to the fire sensor 2 that has detected the fire. It can also be configured to recognize where a fire is detected.

In this case, when a plurality of transmitting/receiving devices 7 are arranged in the security zone R, a plurality of security zones r exist in one security zone R, and the security zone r is a narrower range than the security zone R. become.
Then, for example, in a correspondence table or the like, the specific information E of each fire sensor 2 and each caution area r are associated in advance, and based on this, the caution area r to which the fire detector 2 that has detected the fire belongs is recognized. It is also possible to configure

In addition, in the fire alarm system 1 according to the present embodiment, the warning area information C and the like have been transmitted from the receiver 4 to the server 8, but due to a failure of the transmitting device 6, etc., the fire is notified from the transmitting and receiving device 7 to the server 8. If the specific information E of the detected fire sensor 2 is not transmitted, for example, the server 8 receives the alarm location information H that does not include the information on the position F (that is, the alarm location to which the fire sensor 2 that detected the fire belongs). only the information of the map G of the area R3) is transmitted to the information terminal 9.
In this case, for example, the map G can be displayed on the display screen 91 of the information terminal 9, and a text display 92 or the like indicating that the fire detector 2 that detected the fire cannot be specified can be displayed. be.

Conversely, when the specific information E of the fire detector 2 that detected the fire has been transmitted from the transmitting/receiving device 7 to the server 8, but the warning area information C etc. has not been transmitted from the receiver 4, for example , the server 8 can be configured not to transmit the alarm location information H from the server 8 to the information terminal 9, assuming that the transmitting device 6 has malfunctioned or the transmitting/receiving device 7 has received an erroneous signal. be.
Alternatively, even in such a case, the server 8 transmits the alarm location information H to the information terminal 9 to display the map G and the position F of the fire detector 2, and a text display 92 to the effect that there is a possibility of false alarm. It is also possible to configure to perform

[Indication of equipment such as fire extinguishers]
Using the configuration of the fire alarm system 1 described above, for example, the server 8 manages tools necessary for disaster prevention, fire extinguishing, evacuation, etc., such as fire extinguishers and helmets provided in the restricted areas R1 to R4. It is possible to configure
Further, when the server 8 transmits the location information H to the information terminal 9 as described above, the server 8 also transmits tool information to the information terminal 9 and displays it on the information terminal 9. is also possible.

Specifically, an IC tag, a sensor, or the like is attached to the tool in advance, and the tool is brought into the caution area R (for example, the caution area R3) and installed at a predetermined installation location.
Then, the transmitting/receiving device 7 reads the information from the IC tag or the like of the tool and transmits the information to the server 8 via the communication network N. FIG. Therefore, identification information such as equipment attributes (such as “fire extinguisher” and “helmet”) and numbers are transmitted to the server 8 via the transmission/reception device 7 .

On the other hand, in the fire alarm system 1 according to the present embodiment, as described above, when the fire sensor 2 detects a fire, the receiver 4 that has received the fire detection signal A from the fire sensor 2 sends the signal to the server 8. , warning area information C and the like are transmitted. Further, the unique information E of the fire sensor 2 and the like are transmitted from the transmission device 6 to the server 8 . Therefore, the server 8 was able to specify that the caution area R to which the fire sensor 2 that detected the fire belongs is the caution area R3 based on the information.
However, as described above, even if the tool is brought into the restricted area R3 and installed, the fire sensor 2 does not operate, so the restricted area information C is not transmitted from the receiver 4 to the server 8.

Therefore, in order for the server 8 to be able to specify that the caution area R in which the equipment is installed is the caution area R3, for example, the caution area R in which the equipment is installed is the caution area R3. can be written in an IC tag or the like.
However, with this configuration, for example, every time a tool installed in the caution area R3 is moved to another caution area R (for example, the caution area R2) and installed, the IC tag or the like must be rewritten. is troublesome, and problems such as forgetting to rewrite may occur.

Therefore, in this case, when the transmitting/receiving device 7 reads the identification information (attribute, number, etc.) from the IC tag or the like of the equipment brought into the restricted area R3 and then transmits the identification information to the server 8, At the same time, the identification information of the transmitting/receiving device 7 itself is also transmitted.
Further, the server 8 has a correspondence table in which the identification information of the transmitting/receiving device 7 and the restricted area R in which the transmitting/receiving device 7 is arranged are associated with each other.

Then, when the identification information of the equipment and the identification information of the transmission/reception device 7 are transmitted from the transmission/reception device 7, the server 8 determines that the equipment is in the caution area R ( In the above case, it is possible to configure so as to recognize that it is installed in the restricted area R3) and manage it.
With this configuration, if the equipment is installed in the restricted area R, the server 8 can recognize it. If it disappears, it may not be recognized.

Therefore, for example, each transmitting/receiving device 7 can be configured to periodically read the IC tag or the like of each tool and transmit it to the server 8 .
With this configuration, when the identification information of a certain tool that has been transmitted from a certain transmitting/receiving device 7 is no longer transmitted, the server 8, on the basis of this, determines that the tool is located in the security area where the transmitting/receiving device 7 is located. It can be recognized that it no longer exists in R.
Therefore, with this configuration, the server 8 can accurately manage the presence or absence and type of equipment installed in the caution area R (that is, which equipment is installed) for each caution area R. It becomes possible.

When the server 8 transmits the information about the place where the alarm is issued to the information terminal 9 as described above, the information of each tool installed in the caution area R is also transmitted to the information terminal 9. As shown in , when the map G of the warning area R is displayed on the display screen 91 of the information terminal 9 or the position F of the fire detector 2 that detected the fire is displayed on the map G, the warning It is possible to display the tools 93 installed in the area R as well.
With this configuration, when the fire prevention manager or the like looks at the information terminal 9 and grasps the position F of the fire detector 2 that detected the fire, tools such as a fire extinguisher and a helmet are installed in the caution area R. It is possible to recognize at a glance whether or not there is a fire and what kind of equipment is installed, and to take appropriate measures such as initial fire extinguishing and evacuation.

Although FIG. 5 shows a case where tools such as a fire extinguisher and a helmet are displayed on the display screen 91 of the information terminal 9 by illustration, they may be displayed by letters, symbols, or the like. It is also possible to display the equipment by coloring it in a predetermined color.
Further, as shown in FIG. 5, when a fire hydrant or the like is installed in the restricted area R, the installation location 94 of the information terminal 9 may be displayed on the display screen 91 so that the installation location 94 can be understood. is also possible.

Further, although illustration is omitted, for example, if the transmitting/receiving device 7 reads the identification information of the information terminal 9 possessed by the fire prevention manager or the like and transmits the identification information of the transmitting/receiving device 7 and the like to the server 8, the information On the display screen 91 of the terminal 9, which information terminal 9 is in the displayed caution area R (or in the caution area r described above), that is, in the caution area R (or in the caution area r) It is possible to display who (which fire prevention manager, etc.) is there.
Therefore, it is possible for fire prevention managers and the like to appropriately take measures such as initial fire extinguishing and evacuation while confirming each other's positions.

[Regarding configuration during maintenance and inspection]
By the way, if the fire alarm system 1 according to the present embodiment described above performs the same processing as during the normal warning (see FIG. 4 etc.) even during maintenance inspection of the fire sensor 2, the maintenance inspection worker Every time a simulated fire for testing is caused by hitting the heating tester against the fire detector 2, etc., the map G of the restricted area R is displayed on the information terminal 9 of the fire prevention manager or guard. Undesirable situations may occur, such as misunderstanding that a fire actually broke out.
Therefore, when a maintenance and inspection worker causes a simulated fire for testing during maintenance and inspection, it is necessary to configure the server 8 so that the notification location information H is not transmitted to the information terminal 9 of the fire prevention manager or the like. be.

On the other hand, at the time of maintenance inspection, a display similar to the display on the information terminal 9 possessed by the fire prevention manager shown in FIGS. If configured to display the map G of R and the position F of the fire sensor 2 that detected the pseudo fire), the maintenance and inspection worker can view the display on the information terminal for maintenance and inspection while viewing the fire sensor. 2 can be checked individually, and maintenance and inspection work can be performed easily and reliably.

Therefore, in this embodiment, at the time of maintenance and inspection, the server 8, as shown in FIG. is transmitted only to the maintenance and inspection information terminal 11 possessed by the maintenance and inspection worker.
At the time of maintenance and inspection, the server 8 does not transmit the information of the position F in the caution area R of the fire sensor 2 that detected the simulated fire for testing to the information terminal 9 possessed by the disaster prevention manager or the like.

Hereinafter, the flow of information, signals, etc. during maintenance and inspection in the fire alarm system 1 according to this embodiment will be described in chronological order based on FIG.
The maintenance and inspection worker first operates the information terminal 11 for maintenance and inspection to transmit an inspection mode signal J from the information terminal 11 to the server 8 . The inspection mode signal J can also be configured to be transmitted from the information terminal 11 for maintenance and inspection to the server 8 via the transmission/reception device 7 or the like, as is the case with the inspection mode release signal M described later. is.
Also, the maintenance and inspection worker or another maintenance and inspection worker or the like operates the receiver 4 to shift the receiver 4 to the inspection mode.

Then, the server 8 grasps the inspection area Ra in which maintenance and inspection work is being performed as follows.
When the maintenance/inspection worker enters the receivable range of the transmission/reception device 7 (that is, the warning region r described above), the transmission/reception device 7 receives the identification information K of the maintenance/inspection information terminal 11 possessed by the maintenance/inspection worker. read. When the transmitting/receiving device 7 reads the identification information K of the information terminal 11 for maintenance and inspection, it transmits the read identification information K of the information terminal 11 and its own identification information L to the server 8 .

When a maintenance and inspection worker moves within the alert area r of each transmitter/receiver 7 for maintenance and inspection, each transmitter/receiver 7 reads the identification information K of the information terminal 11 for maintenance and inspection one after another. Then, the identification information L of the transmitting/receiving device 7 and the identification information K of the information terminal 11 are transmitted one after another.
The server 8 stores a correspondence table that associates the identification information L of the transmission/reception device 7 with the caution area r.

In this embodiment, the server 8 finally reads the identification information K of the information terminal 11 for maintenance and inspection, and places the maintenance and inspection worker in the warning area r corresponding to the transmitting/receiving device 7 that has transmitted it together with its own identification information L. , and it is recognized that maintenance and inspection work is being carried out in the caution area r.
That is, in this embodiment, when the identification information K of the information terminal 11 for maintenance and inspection and the identification information L of the transmitting/receiving device 7 are transmitted, the server 8 stores them, and finally transmits the identification information L. The warning area r corresponding to the transmitting/receiving device 7 is recognized as the inspection area Ra in which maintenance and inspection work is being performed.

Thus, in this embodiment, when the server 8 receives the identification information K of the information terminal 11 for maintenance and inspection and the identification information L of the transmission/reception device 7, the identification information L of the transmission/reception device 7 (the last transmitted Based on the identification information L) of the transmitting/receiving device 7, an inspection area Ra in which maintenance and inspection work is being performed is determined.
By configuring in this manner, maintenance and inspection work can be performed by utilizing the fact that each transmitting/receiving device 7 automatically reads the identification information K of the information terminal 11 for maintenance and inspection carried by the maintenance and inspection worker. The server 8 can accurately find out and recognize the inspection area Ra that is set.

On the other hand, during maintenance and inspection work, if a maintenance and inspection worker causes a simulated fire for testing by, for example, hitting the heating tester 12 (see FIG. 6) against the fire sensor 2, the fire alarm system 1 The same process as in the case of a real fire is performed.
That is, as shown in FIG. 7, a fire detection signal A is transmitted to the receiver 4 from the fire sensor 2 that has detected a simulated fire. After receiving the fire detection signal A, the receiver 4 transmits the fire information B and the warning area information C to the server 8 via the communication device 5 .

Further, the transmitting device 6 transmits the fire information D and the unique information E of the fire sensor 2 when the fire sensor 2 detects a simulated fire.
When receiving the fire information D and the unique information E of the fire sensor 2 transmitted from the transmitting device 6, the transmitting/receiving device 7 transmits the fire information D and the unique information E of the fire sensor 2 via the communication network N. Send to server 8.

Based on the information, the server 8 determines the position F in the warning area R of the fire sensor 2 that detected the simulated fire for testing (also determines the inspection area Ra where the above-mentioned maintenance and inspection work is being performed). ), as described above, at the time of maintenance and inspection, the server 8 provides the information of the position F in the caution area R of the fire sensor 2 that has detected the calculated simulated fire for testing to the maintenance and inspection worker. It is transmitted only to the information terminal 11 for maintenance and inspection that it possesses.
It is not transmitted to the information terminal 9 possessed by the disaster prevention manager or the like.

Then, when the receiver 4 transmits the warning area information C and the like to the server 8 via the communication device 5, it automatically transmits the restoration signal I to the fire detector 2 that detected the simulated fire, 2 is returned to its original state (a state in which no fire is detected).
Each of the above processes is repeated each time the maintenance and inspection worker causes the fire sensor 2 to generate a simulated fire for testing.
It should be noted that the reading of the identification information K of the information terminal 11 for maintenance and inspection by the transmitting/receiving device 7 and the transmission of the identification information K and L to the server 8 are maintenance and inspection work (a fire detection signal from the fire sensor 2 to the receiver 4). A to the transmission of the recovery signal I by the receiver 4), and also when the maintenance and inspection worker moves during the maintenance and inspection work.

Then, when the work for all the fire sensors 2 to be inspected is completed, the maintenance inspection worker operates the information terminal 11 for maintenance inspection and transmits an inspection mode release signal M from the information terminal 11 to the server 8. . Also, the maintenance and inspection worker or another maintenance and inspection worker or the like operates the receiver 4 to release the inspection mode.
In this way, the fire alarm system 1 returns to the normal alert state.

Since the fire alarm system 1 according to the present embodiment is configured as described above, if the fire sensor 2 is operating normally, the maintenance and inspection worker applies the heating tester 12 to the fire sensor 2. When a simulated fire for testing is generated in such a manner, a display similar to that shown in FIG. 5 is made on the information terminal 11 for maintenance and inspection.
Therefore, the maintenance and inspection worker can use the map G of the caution area R (the caution area Ra where maintenance and inspection work is being performed) displayed on the information terminal 11, and the fire that detected the simulated fire displayed on the map G. By confirming the position F of the sensor 2, it is possible to easily and reliably confirm that the fire sensor 2 is operating normally.

During maintenance and inspection, the information terminal 9 possessed by the disaster prevention manager or the like does not display the map G of the caution area R, the position F of the fire sensor 2 that detected the simulated fire for testing, and the like.
Therefore, it is possible to reliably prevent a situation in which a fire prevention manager or the like misunderstands that a fire has actually occurred during maintenance and inspection.

When displaying the position F of the fire sensor 2 that detected a simulated fire on the information terminal 11 for maintenance and inspection, in order to make it clear that it is a simulated fire, for example, when displaying when an actual fire occurs It is desirable to display the position F of the fire sensor 2 at which the simulated fire is detected in a manner different from that at the time of actual fire occurrence, such as displaying in a color different from the color of .
In addition, it is possible to display a message or the like without changing the display mode of the position F or to change the display mode of the position F so that it can be distinguished from an actual fire outbreak.

Further, as described above, since the pseudo alarm information of each fire sensor 2 at the time of maintenance inspection is stored in the server 8, the server 8 prepares the test inspection table based on the alarm information. It can also be configured to create automatically.
In that case, it is desirable that the inspection table created by the server 8 can be checked on the information terminal 11 by a maintenance inspection worker or the like.

[In case of fire during maintenance inspection]
By the way, if a fire actually breaks out during maintenance and inspection of the fire sensor 2, the occurrence of the fire must be properly detected.
When a fire actually breaks out in the caution area Ra where maintenance and inspection work is being performed, maintenance and inspection workers who are performing maintenance and inspection work in the caution area Ra can recognize it. In addition, even if the maintenance and inspection worker does not notice the occurrence of fire, the position F of the fire sensor 2 that detected the occurrence of the fire is displayed on the information terminal 11 for maintenance and inspection. Since it is displayed on the top, maintenance and inspection workers can recognize the occurrence of fire.

However, when a fire actually breaks out in a caution area R other than the caution area Ra where maintenance and inspection work is being carried out, maintenance and inspection workers may not necessarily notice it.
Therefore, in this embodiment, when the unique information E of the fire sensor 2 is transmitted from a transmitting/receiving device 7 during the inspection work, the server 8 performs If the warning area R to which the fire sensor 2 identified by the above-described method belongs is a warning area R that does not include the inspection area Ra in which the maintenance and inspection work is being performed, which is determined as described above, maintenance and inspection information Information on the map G of the restricted area R to which the fire sensor 2 corresponding to the identified unique information E belongs and the position of the fire sensor 2 in the restricted area R are sent to the terminal 11 or the information terminal 9 possessed by the disaster prevention manager, security guard, or the like. F information is transmitted.

With this configuration, however, when the fire sensor 2 is activated due to a fire occurring in the warning area R to which the inspection area Ra in which maintenance and inspection work is being performed does not belong, the normal fire occurrence Similarly, the information terminals 9 and 11 of disaster prevention managers, security guards, inspection workers, etc., display a map G of the caution area R and the position F of the fire detector 2 that detected the fire.
Therefore, even during maintenance and inspection work, if a fire actually breaks out in the caution area R to which the inspection area Ra in which maintenance and inspection work is being performed does not belong, the fire prevention manager or the like can use the information terminals 9 and 11 Based on the display, it is possible to recognize with certainty that there is a possibility that a fire has actually broken out, and it is possible to rush to the caution area R and take measures such as initial fire extinguishing, reporting, and evacuation. Become. Moreover, in the case of false alarm, it becomes possible to confirm that it is false alarm.

For example, as described above, when the fire sensor 2 is activated in the warning area R to which the inspection area Ra in which the maintenance and inspection work is being performed does not belong, the inspection mode of the server 8 or the like is automatically changed. It is also possible to configure it so that it is automatically released.
In the above embodiment, the inspection mode signal J is configured to be transmitted only to the server 8 (or to the server 8 and the receiver 4). It is also possible to configure

It goes without saying that the present invention is not limited to the above-described embodiments, and can be modified as appropriate without departing from the gist of the present invention.
