1. 1. First Embodiment 1-1. Configuration The fire extinguishing system 1 according to the first embodiment of the present invention will be described with reference to the drawings.
The fire extinguishing system 1 according to the present embodiment is a sprinkler facility such as a water discharge type head installed on a high ceiling portion of a building B. FIG. 1 is a block diagram showing the configuration of the fire extinguishing system 1. The fire extinguishing system 1 shown in the figure includes an automatic fire alarm system 2, a central operation panel 3, a plurality of nozzle units 4, a field control panel 5, and a field operation unit 6. Hereinafter, each component will be described.

1-1-1. Automatic fire alarm system 2
The automatic fire alarm system 2 includes a plurality of detectors installed in the high ceiling portion of the building B and an R-shaped fire receiver installed in the disaster prevention center of the building B (all not shown). Of these, the detector is, for example, a smoke detector or a flame detector, and transmits an analog value indicating the measured physical quantity to the fire receiver. When the physical quantity measured by the detector exceeds a predetermined threshold value and the duration thereof exceeds a predetermined time, the fire receiver transmits a detector alarm signal to the central operation panel 3. This detector alert signal contains information indicating the fire zone of the alarm that has been alerted.

1-1-2. Central control panel 3
The central operation panel 3 is a device for automatically or manually remotely controlling the nozzle unit 4. The central operation panel 3 is installed in the disaster prevention center of the building B and is connected to the fire receiver via the signal line L1. FIG. 2 is a block diagram showing an example of the internal configuration of the central operation panel 3. The central operation panel 3 shown in the figure includes a control unit 31, a storage unit 32, a display unit 33, an operation unit 34, and a communication unit 35.

Of these, the control unit 31 is composed of a processor and a memory, and various functions are realized by the processor executing a program stored in the memory. The functions to be realized include a nozzle control unit 311, a nozzle information management unit 312, a test unit 313, a display control unit 314, a partition information management unit 315, and a partition information synchronization unit 316.

Of these, the nozzle control unit 311 controls the nozzle unit 4 in response to a detector alarm signal transmitted from the fire receiver or in response to an operation by center personnel.

The nozzle information management unit 312 acquires and manages nozzle information from each nozzle unit 4 in order to support operations by center personnel. Specifically, the nozzle information referred to here is the state information of the nozzle unit 4, the operation right information, and the local independent information. Of these, the local independent information is information indicating whether or not the local control panel 5 is in a state of not accepting control from the central operation panel 3 (in other words, a local independent state). When the nozzle unit 4 in the local independent state is discharging water, the water discharge of the other nozzle units 4 is restricted.

Next, the test unit 313 periodically conducts an operation test of the on-site operation unit 6 connected to the central operation panel 3. The operation test referred to here is a test for confirming the communication state of the on-site operation unit 6. The test unit 313 sends a status confirmation command to the on-site operation unit 6, determines that it is normal if it can receive a response, and determines that it is abnormal if it cannot receive a response. By periodically performing the operation test in this way, it is possible to prevent a situation in which the on-site operation unit 6 cannot be used when it is used.

The display control unit 314 generates an operation screen of the central operation panel 3 and displays it on the display unit 33. The displayed screen includes an inspection screen. This inspection screen is a screen showing the result of the operation test of the on-site operation unit 6. FIG. 3 is a diagram showing an example of this inspection screen. The inspection screen shown in the figure shows that the communication state of the on-site operation unit 6A is normal and the communication state of the on-site operation unit 6B is abnormal.

The division information management unit 315 manages division information in order to support operations by center personnel. The section information referred to here is information in which the identification information of the protected section and the identification information of the nozzle unit 4 set in the protected section are associated with each other. This section information is edited on the board surface of the central operation panel 3 or on the PC connected to the central operation panel 3.

The division information synchronization unit 316 synchronizes the division information stored in the local operation unit 6 with the division information stored in the central operation panel 3. This synchronization process is executed when the central operation panel 3 is started and when the partition information is updated in the central operation panel 3. By this synchronization processing, the partition information stored in the on-site operation unit 6 can be maintained in the latest state.

1-1-3. Nozzle unit 4
Next, the nozzle unit 4 will be described.
The nozzle unit 4 is a fire extinguishing device installed on a high ceiling portion of a building B, and is specifically a movable head. As shown in FIG. 1, the nozzle unit 4 is communicably connected to the central operation panel 3 via a loop-shaped wiring L2. Further, the nozzle unit 4 is communicably connected to the on-site control panel 5 via the loop-shaped wiring L3. That is, the nozzle unit 4 is not individually connected to the central operation panel 3 and the on-site control panel 5. Therefore, the number of wirings connected to the central operation panel 3 and the on-site control panel 5 is reduced as compared with the case of connecting them individually.

The nozzle unit 4 includes a water discharge unit 41, a sensing unit 42, a control unit 43, and a signal relay unit 44 (for the water discharge unit 41 and the sensing unit 42, see FIG. 4. The control unit 43 and the signal relay unit). 44 is not shown).

The water discharge unit 41 is a combination nozzle in which three types of heads, long-throw, medium-throw, and near-throw, are integrated.

The sensing unit 42 includes an infrared linear sensor 421 and a flame detector 422. Of these, the infrared linear sensor 421 searches for a high temperature point in the caution area and detects its direction. On the other hand, the flame detector 422 is an infrared three-wavelength flame detector, and detects a fire source in the direction detected by the infrared linear sensor 421.

The control unit 43 receives signals from the central operation panel 3 and the on-site control panel 5, and controls the water discharge unit 41 and the sensing unit 42 according to the received signals. In addition, the state information, the operation right information, and the local independent information of the nozzle unit 4 are managed according to the received signal. Among these information, the states represented by the state information include storage, fire source exploration, fire source determination, water discharge, anomaly and fouling. Among these states, the abnormality is a power supply abnormality, a turning abnormality, a detection abnormality, or a communication abnormality. The fouling is a fouling of the light receiving window of the sensing unit 42.

The signal relay unit 44 relays signals exchanged between another nozzle unit 4 and the central operation panel 3 or the on-site control panel 5.

FIG. 4 is a diagram showing the operation of the nozzle unit 4 when a fire occurs.
The nozzle unit 4 is stored in a state of being embedded in the wall surface in normal times (FIG. 4A). In this state, when the search start signal is input from the central operation panel 3, the nozzle unit 4 is activated, and the water discharge unit 41 and the sensing unit 42 are integrated to start turning (FIG. 4 (b)). After the start of the turn, the infrared linear sensor 421 searches for a high temperature point in the caution area and detects its direction (FIG. 4 (c)). When the direction of the high temperature point is detected, the front surface of the flame detector 422 is directed to the detected direction, and the flame detector 422 detects the fire source F in that direction (FIG. 4 (d)). When the fire source F is detected, the control unit 43 transmits a fire source position signal indicating the turning angle to the central operation panel 3. After transmitting the fire position signal, the nozzle port of the water discharge unit 41 is directed to the detected fire source F, and the nozzle unit 4 is in a standby state in that state (FIG. 4 (e)). After that, when the water discharge start signal is transmitted from the central operation panel 3 to the nozzle unit 4, water is discharged from the water discharge unit 41 to the fire source F.

1-1-4. Local control panel 5
Next, the on-site control panel 5 will be described.
The on-site control panel 5 is a device for manually and remotely controlling the nozzle unit 4. The on-site control panel 5 is installed in a protected area where the nozzle unit 4 is installed.

The on-site operation unit 6 is provided with a touch screen 62 as described later, and the on-site control panel 5 is operated using the on-site operation unit 6. Therefore, the on-site control panel 5 does not need to be provided with a display unit and an operation unit. Therefore, the on-site control panel 5 can be downsized as compared with the conventional on-site operation panel.

In addition, the on-site operation unit 6 is portable and is connected to the on-site control panel 5 via a cable. Therefore, the user of the on-site operation unit 6 can operate the control panel at a position away from the on-site control panel 5. For example, the user can move to a position where the nozzle unit 4 can be seen and operate the on-site control panel 5. Therefore, unlike the conventional on-site operation panel, the on-site control panel 5 does not need to be installed at a position where the nozzle unit 4 can be seen. That is, the on-site control panel 5 has a high degree of freedom in installation. Further, since the on-site control panel 5 can be installed in an inconspicuous position, for example, it is not necessary to consider manufacturing it according to the color of the wall at the installation location.

Next, the internal configuration of the on-site control panel 5 will be described.
FIG. 5 is a block diagram showing an example of the internal configuration of the field control panel 5. The on-site control panel 5 shown in the figure includes a control unit 51, a storage unit 52, and a communication unit 53. Of these, the control unit 51 is composed of a processor and a memory, and various functions are realized by the processor executing a program stored in the memory. The functions to be realized include a nozzle information management unit 511, a nozzle information output unit 512, and a nozzle control unit 513.

The nozzle information management unit 511 acquires and manages nozzle information from each nozzle unit 4 in order to support operations by center personnel. As described above, the nozzle information referred to here is the state information of the nozzle unit 4, the operation right information, and the local independent information.

The nozzle information output unit 512 outputs the nozzle information stored in the on-site control panel 5 to the on-site operation unit 6.

The nozzle control unit 513 controls the nozzle unit 4 in response to an operation signal input from the on-site operation unit 6.

The functions to be realized include a nozzle information acquisition unit 661, a display control unit 662, and an operation signal output unit 663.

The nozzle information acquisition unit 661 acquires nozzle information from the on-site control panel 5. The acquisition of the nozzle information is performed when the on-site operation unit 6 is connected to the on-site control panel 5 and activated, and when the on-site control panel 5 updates the nozzle information.

The display control unit 662 generates an operation screen of the on-site control panel 5 based on the nozzle information acquired by the nozzle information acquisition unit 661 and the section information stored in the storage unit 67. Then, the generated operation screen is displayed on the touch screen 62.

When an operation is input to the touch screen 62, the operation signal output unit 663 outputs a signal representing the input operation to the on-site control panel 5.

Next, the operation screen generated by the display control unit 662 will be described. FIG. 8 is a diagram showing an example of a nozzle selection screen.

1-2. Operation The operation of the fire extinguishing system 1 will be described. Specifically, the communication operation, the fire extinguishing operation, and the water discharge stop / recovery operation will be described.

1-2-1. Communication operation The central operation panel 3 and the on-site control panel 5 communicate with each nozzle unit 4 by a polling method. The polling method referred to here is a communication method in which the master device periodically inquires of a plurality of slave devices whether or not there is a data transmission request. The central operation panel 3 and the on-site control panel 5 alternately switch between the first transmission mode and the second transmission mode for each poll when communicating by this polling method. FIG. 14 is a diagram showing a first transmission mode, and FIG. 15 is a diagram showing a second transmission mode. In both figures, the control panel 7 shows the central operation panel 3 and the on-site control panel 5.

In the first transmission mode shown in FIG. 14, the control panel 7 transmits a signal by a clockwise route (see arrow A1). On the other hand, each nozzle unit 4 returns a signal by a counterclockwise route (see arrow A2). On the other hand, in the second transmission mode shown in FIG. 15, the control panel 7 transmits a signal by a counterclockwise route (see arrow A3). On the other hand, each nozzle unit 4 returns a signal by a clockwise route (see arrow A4). By changing the signal transmission route for each polling in this way, communication between the control panel 7 and each nozzle unit 4 becomes possible even if a communication failure occurs in a part of the network. For example, when the wiring between the control panel 7 and the nozzle unit 4a is broken, the control panel 7 cannot communicate with each nozzle unit 4 in the first transmission mode, but with each nozzle unit 4 in the second transmission mode. Can communicate.

When an event such as a search start command or a water discharge command occurs, the control panel 7 stores the generated event in the event list. Then, when an event exists in the event list, the polling regarding the event is performed by interrupting at a rate of once every two normal polling cycles. On the other hand, if no event exists in the event list, polling for status confirmation is performed for each nozzle unit 4. In this polling, the state of each nozzle unit 4 and the location of the operation right are confirmed.

1-2-2. Fire extinguishing operation Next, the fire extinguishing operation will be described. Specifically, the automatic fire extinguishing mode and the manual fire extinguishing mode will be described. Here, the automatic fire extinguishing mode is a fire extinguishing mode that automatically performs a series of operations from the detection of a fire to the discharge of water. On the other hand, in the manual fire extinguishing mode, the process from detecting the fire to selecting the optimum nozzle unit 4 for water discharge is automatically performed, and the water discharge is started according to the operation of the central operation panel 3 or the on-site operation unit 6. The mode. These two fire extinguishing modes can be switched by operating the panel surface of the central operation panel 3.

1-2-2-1. Automatic fire extinguishing mode FIG. 16 is a sequence diagram showing an automatic fire extinguishing mode.
When the central operation panel 3 receives the detector alarm signal from the fire receiver (step Sa1), the central operation panel 3 identifies the nozzle unit 4 installed in the warning area of the alarm detector (step Sa2). Then, the search start signal is transmitted to the specified nozzle unit 4 (step Sa3). At that time, if the ACK from the nozzle unit 4 cannot be confirmed, the central operation panel 3 performs a retry. If it cannot be confirmed even after the retry, it will continue after the next polling cycle.

Upon receiving the search start signal, the nozzle unit 4 starts the fire source search (step Sa4). In addition, the status information of the own aircraft is updated from "storage" to "exploration". Then, when the fire source is detected as a result of the fire source search (step Sa5), a fire source position signal indicating the turning angle at the time of detecting the fire source is transmitted to the central operation panel 3 (step Sa6). In addition, the status information of the own aircraft is updated from "exploration" to "confirmed".

The central operation panel 3 receives the fire source position signal from all the nozzle units 4 in the fire section, or when a predetermined time has elapsed after receiving the first report of the fire source position signal, the received fire source position is received. The optimum nozzle unit 4 for water discharge is selected based on the signal (step Sa7). For the method of selecting the nozzle unit 4 at that time, refer to, for example, Japanese Patent Application Laid-Open No. 2000-093540. When the central operation panel 3 selects the nozzle unit 4 most suitable for water discharge, the central operation panel 3 activates a fire extinguishing pump (not shown) (step Sa8). In addition, a water discharge start signal is transmitted to the selected nozzle unit 4 (step Sa9). At that time, if the ACK from the nozzle unit 4 cannot be confirmed, the central operation panel 3 performs a retry. If it cannot be confirmed even after the retry, it will continue after the next polling cycle.

When the nozzle unit 4 receives the water discharge start signal, the nozzle unit 4 transfers the signal to the on-site control panel 5 (step Sa10). Upon receiving this water discharge start signal, the on-site control panel 5 opens the start valve (not shown) corresponding to the nozzle unit 4 (step Sa11). As a result, water is discharged from the nozzle unit 4 to the fire source.

After the start valve is released, when the on-site control panel 5 receives an on signal from the pressure switch (not shown) installed on the secondary side of the start valve (step Sa12), the water discharge signal indicating that the water discharge has started is started. Is transmitted to the nozzle unit 4 (step Sa13). Upon receiving this water discharge, the nozzle unit 4 updates the state information of its own machine from "determined" to "water discharge" (step Sa14).
The above is the description of the automatic fire extinguishing mode.

1-2-2-2. Manual fire extinguishing mode FIG. 17 is a sequence diagram showing a manual fire extinguishing mode. In the manual fire extinguishing mode shown in the figure, it is assumed that water discharge is started in response to the operation of the central operation panel 3.

After selecting the nozzle unit 4 most suitable for water discharge (step Sa7), the central operation panel 3 transmits an operation request signal to the nozzle unit 4 when the operation right acquisition operation is performed by the center personnel (step Sb1) (step Sb1). Step Sb2). At that time, if the ACK from the nozzle unit 4 cannot be confirmed, the central operation panel 3 performs a retry. If it cannot be confirmed even after retrying, the operation is terminated. Upon receiving the operation request signal, the nozzle unit 4 updates the operation right information of its own machine to the "central operation panel" (step Sb3). This update of the operation right information is also reflected in the operation right information stored in the central operation panel 3 through the status confirmation. As a result, the central operation panel 3 can perform the water discharge preparation operation.

After that, when the water discharge preparation operation is performed by the center personnel (step Sb4), the central operation panel 3 transmits a water discharge preparation signal to the nozzle unit 4 (step Sb5). At that time, if the ACK from the nozzle unit 4 cannot be confirmed, the central operation panel 3 performs a retry. If it cannot be confirmed even after retrying, the operation is terminated. Upon receiving the water discharge preparation signal, the nozzle unit 4 updates the state information of its own machine from "confirmation" to "preparation" (step Sb6). This update of the status information is also reflected in the status information stored in the central operation panel 3 through the status confirmation. As a result, the central operation panel 3 can perform a turning operation and a water discharge operation.

After that, the central operation panel 3 transmits a turning signal to the nozzle unit 4 (step Sb8) when the turning operation is performed by the center personnel (step Sb7). Upon receiving this swivel signal, the nozzle unit 4 swivels the water discharge unit 41 in the direction indicated by the signal (step Sb9).

After that, the central operation panel 3 activates the fire extinguishing pump (step Sb11) when the water discharge operation is performed by the center personnel (step Sb10). In addition, a water discharge start signal is transmitted to the nozzle unit 4 (step Sb12). At that time, if the ACK from the nozzle unit 4 cannot be confirmed, the central operation panel 3 performs a retry. If it cannot be confirmed even after retrying, the operation is terminated.

When the nozzle unit 4 receives the water discharge start signal, the nozzle unit 4 transfers the signal to the on-site control panel 5 (step Sb13). Upon receiving this water discharge start signal, the on-site control panel 5 opens the start valve corresponding to the nozzle unit 4 (step Sb14). As a result, water is discharged from the nozzle unit 4 to the fire source.

After the start valve is released, when the on-site control panel 5 receives an on signal from the pressure switch installed on the secondary side of the start valve (step Sb15), the nozzle unit 4 issues a water discharge signal indicating that water discharge has started. (Step Sb16). Upon receiving this water discharge signal, the nozzle unit 4 updates the state information of its own unit from "determined" to "water discharge" (step Sb17).
The above is the description of the manual fire extinguishing mode.

Next, FIG. 18 is another sequence diagram showing a manual fire extinguishing mode. In the manual fire extinguishing mode shown in the figure, it is assumed that water discharge is started in response to the operation of the on-site operation unit 6 connected to the on-site control panel 5.

After the nozzle unit 4 most suitable for water discharge is selected in the central operation panel 3 (step Sa7), when the operation right acquisition operation is performed on the on-site operation unit 6 by the center personnel (step Sc1), the on-site control panel 5 The operation request signal is transmitted to the nozzle unit 4 (step Sc2). At that time, if the ACK from the nozzle unit 4 cannot be confirmed, the on-site control panel 5 performs a retry. If it cannot be confirmed even after retrying, the operation is terminated. When the nozzle unit 4 receives the operation request signal, it updates the operation right information of its own machine to the "on-site control panel" (step Sc3). This update of the operation right information is also reflected in the operation right information stored in the on-site control panel 5 through the status confirmation. As a result, the on-site operation unit 6 can perform the water discharge preparation operation.

After that, when the center personnel perform a water discharge preparation operation for the on-site operation unit 6 (step Sc4), the on-site control panel 5 transmits a water discharge preparation signal to the nozzle unit 4 (step Sc5). At that time, if the ACK from the nozzle unit 4 cannot be confirmed, the on-site control panel 5 performs a retry. If it cannot be confirmed even after retrying, the operation is terminated. Upon receiving the water discharge preparation signal, the nozzle unit 4 updates the state information of its own machine from "confirmation" to "preparation" (step Sc6). This update of the status information is also reflected in the status information stored in the on-site control panel 5 through the status confirmation. As a result, the on-site operation unit 6 can perform a turning operation and a water discharge operation.

After that, when the center personnel perform a turning operation on the on-site operation unit 6 (step Sc7), the on-site control panel 5 transmits a turning signal to the nozzle unit 4 (step Sc8). When the nozzle unit 4 receives this turning signal, it turns the water discharge unit 41 in the direction indicated by the signal (step Sc9).

After that, when a water discharge operation is performed on the on-site operation unit 6 by the center personnel (step Sc10), the on-site control panel 5 transmits a water discharge request signal to the nozzle unit 4 (step Sc11). At that time, if the ACK from the nozzle unit 4 cannot be confirmed, the on-site control panel 5 performs a retry. If it cannot be confirmed even after retrying, the operation is terminated.

When the nozzle unit 4 receives the water discharge request signal, the nozzle unit 4 transfers the signal to the central operation panel 3 (step Sc12). Upon receiving this water discharge request signal, the central operation panel 3 activates the fire extinguishing pump (step Sc13). In addition, a water discharge start signal is transmitted to the nozzle unit 4 (step Sc14). Upon receiving this water discharge start signal, the nozzle unit 4 transfers the signal to the on-site control panel 5 (step Sc15). Upon receiving this water discharge start signal, the on-site control panel 5 opens the start valve corresponding to the nozzle unit 4 (step Sc16). As a result, water is discharged from the nozzle unit 4 to the fire source.

After the start valve is released, when the on-site control panel 5 receives an on signal from the pressure switch installed on the secondary side of the start valve (step Sc17), the nozzle unit 4 issues a water discharge signal indicating that water discharge has started. (Step Sc18). Upon receiving this water discharge signal, the nozzle unit 4 updates the state information of its own unit from "determined" to "water discharge" (step Sc19).
The above is the description of the manual fire extinguishing mode.

1-2-3. Water discharge stop / recovery operation Next, the water discharge stop / recovery operation will be described. FIG. 19 is a sequence diagram showing a water discharge stop / recovery operation. In the operation shown in the figure, it is assumed that the water discharge is stopped and restored according to the operation of the central operation panel 3.

When the water discharge stop operation is performed by the center personnel (step Sd1), the central operation panel 3 transmits a water discharge stop signal to the nozzle unit 4 (step Sd2). At that time, if the ACK from the nozzle unit 4 cannot be confirmed, the central operation panel 3 performs a retry. If it cannot be confirmed even after retrying, the operation is terminated. When the nozzle unit 4 receives the water discharge stop signal, the nozzle unit 4 transfers the signal to the on-site control panel 5 (step Sd3). Upon receiving this water discharge stop signal, the on-site control panel 5 closes the start valve corresponding to the nozzle unit 4 (step Sd4). As a result, the water discharge from the nozzle unit 4 is stopped.

After closing the start valve, when the on-site control panel 5 receives an off signal from the pressure switch installed on the secondary side of the start valve (step Sd5), the on-site control panel 5 sends a stop signal indicating that the water discharge has stopped to the nozzle unit 4. Transmit (step Sd6). Upon receiving this stop signal, the nozzle unit 4 updates the state information of its own machine from "water discharge" to "confirmed" (step Sd7).

After that, when the center operation panel 3 performs a full recovery operation by the center personnel (step Sd8), the central operation panel 3 transmits an operation request signal to the nozzle unit 4 (step Sd9). At that time, if the ACK from the nozzle unit 4 cannot be confirmed, the central operation panel 3 performs a retry. If it cannot be confirmed even after retrying, the operation is terminated. Upon receiving the operation request signal, the nozzle unit 4 updates the operation right information of its own machine to "open" (step Sd10). The term "open" as used herein means that the operation right does not exist in either the central operation panel 3 or the on-site control panel 5. In addition, the nozzle unit 4 executes a recovery operation (step Sd11), and when the recovery operation is completed, the state information of the own machine is updated from "determined" to "stored".

After that, when the center personnel performs a pump stop operation of the fire extinguishing pump panel (not shown), the central operation panel 3 turns off the display of the fire extinguishing pump operation (step Sd12).
The above is the explanation of the water discharge stop / recovery operation.

Next, FIG. 20 is another sequence diagram showing the water discharge stop / recovery operation. In the operation shown in the figure, it is assumed that the water discharge is stopped and restored according to the operation of the on-site operation unit 6 connected to the on-site control panel 5.

When the water discharge stop operation is performed on the on-site operation unit 6 by the center personnel (step Se1), the on-site control panel 5 transmits a water discharge stop request signal to the nozzle unit 4 (step Se2). At that time, if the ACK from the nozzle unit 4 cannot be confirmed, the on-site control panel 5 performs a retry. If it cannot be confirmed even after retrying, the operation is terminated. When the nozzle unit 4 receives the water discharge stop request signal, the nozzle unit 4 transfers the signal to the central operation panel 3 (step Se3). Upon receiving this water discharge stop request signal, the central operation panel 3 transmits the water discharge stop signal to the nozzle unit 4 (step Se4). When the nozzle unit 4 receives the water discharge stop signal, the nozzle unit 4 transfers the signal to the on-site control panel 5 (step Se5). Upon receiving this water discharge stop signal, the on-site control panel 5 closes the start valve corresponding to the nozzle unit 4 (step Se6). As a result, the water discharge from the nozzle unit 4 is stopped.

After closing the start valve, when the on-site control panel 5 receives an off signal from the pressure switch installed on the secondary side of the start valve (step Se7), the on-site control panel 5 sends a stop signal indicating that the water discharge has stopped to the nozzle unit 4. Transmit (step Se8). Upon receiving this stop signal, the nozzle unit 4 updates the state information of its own machine from "water discharge" to "confirmed" (step Se9).

After that, when the center personnel perform a restoration operation on the on-site operation unit 6 (step Se10), the on-site control panel 5 transmits an operation request signal to the nozzle unit 4 (step Se11). At that time, if the ACK from the nozzle unit 4 cannot be confirmed, the on-site control panel 5 performs a retry. If it cannot be confirmed even after retrying, the operation is terminated. Upon receiving the operation request signal, the nozzle unit 4 updates the operation right information of its own machine to "open" (step Se12). In addition, when the recovery operation is executed (step Se13) and the recovery operation is completed, the status information of the own machine is updated from "confirmed" to "stored".

After that, the central operation panel 3 turns off the display of the fire extinguishing pump operation when the pump stop operation of the fire extinguishing pump panel is performed by the center personnel (step Se14).
The above is the explanation of the water discharge stop / recovery operation.
In the above water discharge stop / recovery operation, the central operation panel 3 outputs a water discharge stop signal, but the nozzle unit 4 may output a water discharge stop signal instead of the central operation panel 3. In that case, the nozzle unit 4 receives the water discharge stop request signal transmitted from the on-site control panel 5, and transmits the water discharge stop signal to the on-site control panel 5.

The portable on-site operation unit 16 includes a display operation panel 163 as described later, and the on-site control panel 15 is operated using the display operation panel 163. Therefore, the on-site control panel 15 does not need to be provided with a display operation panel. Therefore, the on-site control panel 15 can be downsized as compared with the conventional on-site operation panel.

In addition, the on-site operation unit 16 is portable and is connected to the on-site control panel 15 via a cable. Therefore, the user of the on-site operation unit 16 can operate the control panel at a position away from the on-site control panel 15. For example, the user can move to a position where the fixed head 17 can be seen and operate the on-site control panel 15. Therefore, unlike the conventional on-site operation panel, the on-site control panel 15 does not need to be installed at a position where the fixed head 17 can be seen. That is, the on-site control panel 15 has a high degree of freedom in installation. Further, since the on-site control panel 15 can be installed in an inconspicuous position, for example, it is not necessary to consider manufacturing it according to the color of the wall at the installation location.

3-2-1. Automatic water discharge mode FIGS. 27 and 28 are sequence diagrams showing an automatic water discharge mode.
When a fire breaks out in the building C and the smoke detector 11 detects the fire, a fire signal is transmitted to the fire receiver 12. When the fire receiver 12 receives the fire signal, the fire receiver 12 transfers the report to the sprinkler control panel 14. The sprinkler control panel 14 receives the transfer (step Sf1) and turns on the self-fire alarm light Lp5 in the protected area where the fire has occurred (step Sf2). In addition, a self-fire alarm lighting signal is transmitted to the on-site control panel 15 (step Sf3). Upon receiving the self-fire alarm lighting signal, the on-site control panel 15 sets the self-fire alarm light flag of the protected area where the fire has occurred to ON (step Sf4). As a result, when the on-site operation unit 16 is connected to the on-site control panel 15, the on-site operation unit 16 turns on the self-fire alarm light Lp12 in the protected area where the fire has occurred.

After that, when the flame detector 13 detects the fire, the flame detector 13 transmits a fire signal to the sprinkling control panel 14. When the sprinkler control panel 14 receives the fire signal (step Sf5), the sprinkler control panel 14 turns on the fire extinguishing light Lp6 in the protected area where the fire has occurred (step Sf6). In addition, a fire extinguishing light lighting signal is transmitted to the local control panel 15 (step Sf7). Upon receiving the fire extinguishing light lighting signal, the local control panel 15 sets the fire extinguishing light flag of the protected area where the fire has occurred to ON (step Sf8). As a result, when the local operation unit 16 is connected to the local control panel 15, the local operation unit 16 turns on the fire extinguishing light Lp13 in the protected area where the fire has occurred.

When the sprinkler control panel 14 determines that the smoke detector 11 and the flame detector 13 installed in the same protected area have issued a report, it determines that a fire has occurred (step Sf9). Then, the division light Lp4 and the fire light Lp3 of the protected area where the fire occurred are turned on (step Sf10). In addition, the countdown of the water discharge start timer is started (step Sf11), the timer operation lamp Lp8 is blinked, and the remaining time is displayed on the remaining time indicator D (step Sf12). Further, a lighting signal for a partition light or the like is transmitted to the on-site control panel 15 (step Sf13). When the on-site control panel 15 receives the lighting signal of the division light or the like, the on-site control panel 15 sets the division light flag of the protected area where the fire has occurred, the fire light flag, the timer operation light flag, and the operable light flag on (step). Sf14). As a result, when the on-site operation unit 16 is connected to the on-site control panel 15, the on-site operation unit 16 turns on the division light Lp11, the fire light Lp10, and the operable light Lp14 of the protected area where the fire occurred. The timer operation light Lp16 is blinked.

After that, when the countdown of the water discharge start timer is completed (step Sf15), the water sprinkling control panel 14 opens the remote control valve 18 of the protected area where the fire has occurred and transmits a pump start signal to the pump control panel 20 (step Sf16). ). As a result, water is discharged from the fixed head 17 in the protected area where the fire has occurred. As a result of this water discharge, the water spray control panel 14 turns on the water discharge lamp Lp9 when it receives an on signal from a pressure switch (not shown) (step Sf17). In addition, the water discharge light lighting signal is transmitted to the on-site control panel 15 (step Sf18). When the on-site control panel 15 receives the water discharge light lighting signal, the water discharge light flag is set to on and the timer operation light flag is set to off (step Sf19). As a result, when the local operation unit 16 is connected to the local control panel 15, the local operation unit 16 turns on the water discharge light Lp17 and turns off the timer operation light Lp16.

After that, when the disaster prevention personnel confirms the fire extinguishing and presses the water discharge stop switch Sw5 of the water sprinkling control panel 14 (step Sf20), the sprinkling control panel 14 closes the remote control valve 18 opened in step Sf16 (step Sf21). As a result, water discharge from the fixed head 17 is stopped. As a result of this water discharge, the water spray control panel 14 turns off the water discharge lamp Lp9 when it receives an off signal from the pressure switch (step Sf22). In addition, the water discharge light extinguishing signal is transmitted to the on-site control panel 15 (step Sf23). Upon receiving the water discharge light extinguishing signal, the on-site control panel 15 sets the water discharge light flag to off (step Sf24). As a result, when the local operation unit 16 is connected to the local control panel 15, the local operation unit 16 turns off the water discharge lamp Lp17.

After that, when the disaster prevention personnel press the recovery switch Sw6 of the sprinkling control panel 14 (step Sf25), the sprinkling control panel 14 turns off the division lights Lp4, the self-fire alarm light Lp5, and the fire extinguishing light Lp6 of all the protected areas. (Step Sf26). In addition, a signal for turning off the partition lights and the like is transmitted to the on-site control panel 15 (step Sf27). When the on-site control panel 15 receives the extinguishing signal such as the division light, the on-site control panel 15 sets the division light flag, the self-fire alarm light flag, and the fire extinguishing exclusive light flag of all the protected areas to off (step Sf28). As a result, when the on-site operation unit 16 is connected to the on-site control panel 15, the on-site operation unit 16 turns off the division light Lp11, the self-fire alarm light Lp12, and the fire extinguishing light Lp13 of all the protected areas.
The above is the description of the automatic water discharge mode.

In the above automatic water discharge mode, if the disaster prevention personnel confirms the site and determines that it is a non-fire report, the countdown of the water discharge start timer may be stopped. There are two methods for stopping the countdown: a method of operating the key switch Sw1 of the water sprinkling control panel 14 to switch the water discharge mode to the manual water discharge mode, and a method of pressing the timer stop switch Sw8 of the local operation unit 16. Of these two methods, in the latter method, when the timer stop switch Sw8 of the on-site operation unit 16 is pressed, the on-site control panel 15 transmits a timer stop signal to the sprinkling control panel 14. When the sprinkler control panel 14 receives the timer stop signal, the sprinkler control panel 14 stops the countdown.

Further, in the above description, the water discharge control panel 14 is used to instruct the water discharge stop, but instead of the water sprinkling control panel 14, the on-site operation unit 16 may be used to instruct the water discharge stop. In that case, the disaster prevention personnel press the water discharge stop switch Sw11 of the local operation unit 16. In response to this operation, the on-site control panel 15 transmits a water discharge stop signal to the water sprinkling control panel 14. Upon receiving the water discharge stop signal, the water sprinkling control panel 14 closes the remote control valve 18 opened in step Sf16. As a result, water discharge from the fixed head 17 is stopped.

3-2-2. Manual water discharge mode FIGS. 29 and 30 are sequence diagrams showing a manual water discharge mode. Of the steps shown in these figures, steps Sf1 to Sf10 are common to the automatic water discharge mode, and therefore the description thereof will be omitted.

After executing step Sf10, the sprinkling control panel 14 transmits a lighting signal such as a partition light to the on-site control panel 15 (step Sg1). When the on-site control panel 15 receives the lighting signal of the division light or the like, the on-site control panel 15 sets the division light flag, the fire light flag, and the operable light flag of the protected area where the fire has occurred to on (step Sg2). As a result, when the on-site operation unit 16 is connected to the on-site control panel 15, the on-site operation unit 16 turns on the division light Lp11, the fire light Lp10, and the operable light Lp14 of the protected area where the fire occurred.

After that, when disaster prevention personnel check the site and confirm the occurrence of a fire, they instruct manual water discharge. Specifically, on the water sprinkling control panel 14, the water discharge section selection switch Sw3 of the protected section where the fire has occurred is pressed, and then the water discharge start switch Sw4 is pressed. When the sprinkler control panel 14 receives these operations (step Sg3), the sprinkler control panel 14 opens the remote control valve 18 of the selected protected area and transmits a pump start signal to the pump control panel 20 (step Sg4). As a result, water is discharged from the fixed head 17 in the selected protected area. As a result of this water discharge, the water spray control panel 14 turns on the water discharge lamp Lp9 when it receives an on signal from a pressure switch (not shown) (step Sg5). In addition, the water discharge light lighting signal is transmitted to the on-site control panel 15 (step Sg6). Upon receiving the water discharge light lighting signal, the on-site control panel 15 sets the water discharge light flag to ON (step Sg7). As a result, when the local operation unit 16 is connected to the local control panel 15, the local operation unit 16 turns on the water discharge lamp Lp17.

Subsequent steps Sf20 to Sf28 are common to the automatic water discharge mode, and therefore the description thereof will be omitted.
The above is the description of the manual water discharge mode.

In the above description, the water sprinkling control panel 14 is used to instruct manual water discharge, but instead of the water sprinkling control panel 14, the on-site operation unit 16 may be used to instruct manual water discharge. In that case, the disaster prevention personnel presses the water discharge section selection switch Sw9 of the protected area where the fire has occurred in the on-site operation unit 16, and then presses the water discharge start switch Sw10. In response to these operations, the on-site control panel 15 transmits a water discharge start signal to the sprinkling control panel 14. Upon receiving the water discharge start signal, the water sprinkling control panel 14 opens the remote control valve 18 of the selected protected area and transmits a pump start signal to the pump control panel 20. As a result, water is discharged from the fixed head 17 in the selected protected area.

Further, in the above explanation, manual water discharge is instructed after the fire is confirmed, but if the disaster prevention personnel finds a fire before the fire is confirmed, manual water discharge may be instructed before the fire is confirmed. However, when the instruction is given using the on-site operation unit 16, it is necessary to operate the key switch Sw7 to enable the board operation of the on-site operation unit 16 before instructing the manual water discharge.
