The nozzle information management unit 312 acquires and manages the nozzle information from each nozzle unit 4 in order to support operations performed by processing center personnel. The so-called nozzle information here is specifically the status information, operation right information and on-site individual information of the nozzle unit 4 . Among them, the site independent information is information indicating whether the site control panel 5 is in a state that does not receive control from the central operation panel 3 (in other words, it is in a site individual state). When the nozzle unit 4 in the on-site independent state is discharging water, the water discharging of other nozzle units 4 will be restricted.

The test unit 313 regularly performs operation tests of the field operation unit 6 connected to the central operation panel 3 . The so-called operation test here is a test to confirm the communication status of the field operation unit 6 . The test unit 313 transmits a status confirmation command to the on-site operation unit 6, and determines that it is normal as long as a response can be received, and determines that it is abnormal if a response cannot be received. By performing operation tests periodically in this way, it is possible to prevent a situation in which the on-site operation unit 6 cannot be used when it is suddenly used.

The event information management unit 314 manages event information related to the fire that occurred in the building B. Each event information consists of the content and date of the event that occurred.

The display control unit 315 generates an operation screen for the central operation panel 3 based on the nozzle information managed by the nozzle information management unit 312 and the event information managed by the event information management unit 314 . Then, the generated operation screen is displayed on the touch screen 33 .

The area information management unit 316 manages area information in order to support operations performed by processing center personnel. The area information referred to here is information that associates the identification information of the protection area with the identification information of the nozzle unit 4 set in the protection area. This area information is edited on the central operating panel 3 or on a PC connected to the central operating panel 3 .

The area information synchronization unit 317 synchronizes the area information stored in the field operation unit 6 and the area information stored in the central operation panel 3 . This synchronization process is executed when the central operation panel 3 is activated and when the central operation panel 3 updates the area information.

Next, the inspection screen will be described. This inspection screen shows the result of the operation test of the field operation unit 6 . FIG. 14 shows an example of the inspection screen. The inspection screen shown in this figure indicates that the communication status of the field operation unit 6A is normal and the communication status of the field operation unit 6B is abnormal.

1-1-3.Nozzle unit 4 Next, the nozzle unit 4 will be described. The nozzle unit 4 is a fire extinguishing device installed in the high ceiling part of the building B, and is specifically a movable head. As shown in FIG. 1 , the nozzle unit 4 is communicatively connected to the central operation panel 3 via an annular wiring L2. In addition, the nozzle unit 4 is communicably connected to the field control panel 5 via the annular wiring L3. That is, the nozzle unit 4 is not individually connected to the central operating panel 3 and the local control panel 5 . Therefore, compared with the case of individual connection, the number of wirings connected to the central operation panel 3 and the field control panel 5 is reduced.

This nozzle unit 4 is provided with: a water discharge part 41, a sensing part 42, a control part 43, and a signal relay part 44 (among them, for the water discharge part 41 and the sensing part 42, refer to FIG. 15. For the control part 43 and the signal relay part 44, The illustration of the continuation part 44 is omitted).

The water discharge part 41 is a combination nozzle in which three types of heads, namely, long throw, medium throw, and near throw, are integrated into one structure.

The sensing unit 42 includes an infrared linear sensor 421 and a flame detector 422. Among them, the infrared linear sensor 421 detects high-temperature points in the warning area to detect their 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 based on the received signals. In addition, the status information, operation right information and on-site individual information of the nozzle unit 4 are managed according to the received signals. Among these pieces of information, status information represents information on the operating status of the nozzle unit 4 . The status displayed by this status information includes storage, fire source detection, fire source determination, water release, abnormality and stain. Among these states, abnormality refers to power supply abnormality, rotation abnormality, detection abnormality or communication abnormality. Damage refers to damage to the light-receiving window of the sensing unit 42 .

The signal relay unit 44 relays signals exchanged between other nozzle units 4 and the central operation panel 3 or the field control panel 5 .

FIG. 15 is a diagram showing the operation of the nozzle unit 4 when a fire occurs. The nozzle unit 4 is normally stored in a state of being embedded in the wall surface (Fig. 15(a)). In this state, when a search start signal is input from the center operation panel 3, the nozzle unit 4 is activated, and the water discharge part 41 and the sensing part 42 become integrated and start rotating (Fig. 15(b)). After the rotation starts, the infrared linear sensor 421 detects the high temperature point in the warning area to detect its direction (Fig. 15(c)). If the direction of the high-temperature spot is detected, the front of the flame detector 422 faces the direction in which it was detected, and the flame detector 422 detects the fire source F in that direction (Fig. 15(d)). If the fire source F is detected, the control unit 43 transmits a fire source position signal indicating the rotation angle to the central operation panel 3 . After the fire position signal is transmitted, the nozzle opening of the water discharge part 41 faces the detected fire source F. In this state, the nozzle unit 4 enters the standby state (Fig. 15(e)). After that, when a water discharge start signal is transmitted from the central operation panel 3 to the nozzle unit 4, water is discharged from the water discharge part 41 to the fire source F.

1-2. Action The operation of the fire extinguishing system 1 will be explained. Specifically, communication actions, fire extinguishing actions, and water release stop and recovery actions are explained.

1-2-1. Communication actions The central operating panel 3 and the on-site control panel 5 communicate with each nozzle unit 4 in a polling manner. The so-called polling method here refers to the communication method in which the master device periodically queries multiple slave devices for data transmission requirements. When the central operation panel 3 and the field control panel 5 communicate using this polling method, the first transmission mode and the second transmission mode are alternately switched for each polling. FIG. 25 shows a diagram of the first transmission mode, and FIG. 26 shows a diagram of the second transmission mode. In the two figures, the control panel 7 represents the central operation panel 3 and the on-site control panel 5 .

In the first transmission mode shown in FIG. 25, the control panel 7 transmits signals in a clockwise path (see arrow A1). In contrast, each nozzle unit 4 returns a signal in a counterclockwise direction (see arrow A2). On the other hand, in the second transmission mode shown in FIG. 26, the control panel 7 transmits the signal in a counterclockwise direction (see arrow A3). In contrast, each nozzle unit 4 returns a signal along a clockwise path (see arrow A4). In this way, by changing the signal transmission path for each poll, 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 disconnected, the control panel 7 cannot communicate with each nozzle unit 4 in the first transfer mode, but can communicate with each nozzle unit 4 in the second transfer mode.

The control panel 7 stores the generated commands in the command directory when commands such as the exploration start command and the water release command are generated. Then, when there is an instruction in the instruction directory, an interrupt is usually made at a ratio of 1 in 2 polling cycles to perform polling related to the instruction. On the other hand, when there is no command in the command list, polling for status confirmation is performed on each nozzle unit 4 . In this polling, the status and operation authority of each nozzle unit 4 are confirmed.

1-2-2. Fire-fighting actions Next, the fire extinguishing operation will be explained. Specifically, the automatic fire extinguishing mode and the manual fire extinguishing mode will be described. Here, the automatic fire extinguishing mode refers to a fire extinguishing mode that automatically performs a continuous operation from the detection of fire to the release of water. In contrast, the manual fire extinguishing mode refers to a fire extinguishing mode that automatically selects the nozzle unit 4 that is most suitable for discharging water from the detection of fire. Regarding discharging water, it is a fire extinguishing mode that is started based on the operation of the central operation panel 3 or the on-site operation unit 6 . These two fire extinguishing modes can be switched by panel operation of the central operating panel 3.

1-2-2-1. Automatic fire extinguishing mode Fig. 27 shows a sequence diagram of the automatic fire extinguishing mode. When the central operation panel 3 receives the sensor alarm signal from the fire receiver (step Sa1), it defines the nozzle unit 4 installed in the warning area of the sensor after the alarm (step Sa2). Then, a detection start signal is transmitted to the defined nozzle unit 4 (step Sa3). At this time, if the central operation panel 3 cannot confirm the ACK from its nozzle unit 4, it will retry. When confirmation cannot be obtained after retrying, the process will continue after the next polling cycle.

When receiving the detection start signal, the nozzle unit 4 starts fire source detection (step Sa4). In addition, the status information of this machine is updated from "Storage" to "Exploration". Furthermore, when the fire source detection result is that the fire source is detected (step Sa5), a fire source position signal indicating the rotation angle at the time of fire source detection is transmitted to the central operation panel 3 (step Sa6). In addition, the status information of this machine is updated from "Exploring" to "Confirmed".

The central operating panel 3 receives fire source position signals from all the nozzle units 4 in the fire area, or when a predetermined time elapses from the first report of the fire source position signal, the central operating panel 3 determines the fire source position signal based on the received fire source position signal. The signal selects the nozzle unit 4 most suitable for discharging water (step Sa7). Regarding the method of selecting the nozzle unit 4 at this time, refer to Japanese Patent Application Laid-Open No. 2000-093540, for example. When the central operation panel 3 selects the nozzle unit 4 most suitable for discharging water, the fire extinguishing pump is started (step Sa8). In addition, a water discharge start signal is transmitted to the selected nozzle unit 4 (step Sa9). At this time, if the central operation panel 3 cannot confirm the ACK from its nozzle unit 4, it will retry. When confirmation cannot be obtained after retrying, the process will continue after the next polling cycle.

When the nozzle unit 4 receives the water discharge start signal, it transmits the signal to the on-site control panel 5 (step Sa10). When the on-site control panel 5 receives the water discharge start signal, it 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 starting valve is released, the on-site control panel 5 receives the ON signal from the pressure switch (not shown) provided on the secondary side of the starting valve (step Sa12), and transmits a water discharge signal indicating the start of water discharge to Nozzle unit 4 (step Sa13). When the nozzle unit 4 receives the water discharge, it updates the status information of the machine from "confirmation" to "water discharge" (step Sa14). The above are instructions for the automatic fire extinguishing mode.

1-2-2-2. Manual fire extinguishing mode Fig. 28 shows a sequence diagram of the manual fire extinguishing mode. The manual fire extinguishing mode shown in the figure is assumed to start discharging water in accordance with the operation of the central operation panel 3.

The central operation panel 3 transmits an operation request signal to the nozzle unit when the processing center personnel performs the operation right acquisition operation (step Sb1) after the above-mentioned selection of the nozzle unit 4 most suitable for discharging water is selected (step Sa7). 4 (step Sb2). At this time, if the central operation panel 3 cannot confirm the ACK from its nozzle unit 4, it will retry. If confirmation cannot be obtained even after retrying, the operation is terminated. When the nozzle unit 4 receives its operation request signal, it updates the operation right information of the machine to the "central operation panel" (step Sb3). The update of the operation authority information is also reflected in the operation authority information stored on the central operation panel 3 through status confirmation. As a result, the water discharge preparation operation becomes possible on the central operation panel 3 .

After that, when the processing center personnel performs the water discharge preparation operation (step Sb4), the central operation panel 3 transmits the water discharge preparation signal to the nozzle unit 4 (step Sb5). At this time, if the central operation panel 3 cannot confirm the ACK from its nozzle unit 4, it will retry. If confirmation cannot be obtained even after retrying, the operation is terminated. When the nozzle unit 4 receives its water discharge preparation signal, it updates the status information of the machine from "confirmed" to "prepared" (step Sb6). The update of the status information is also reflected in the status information stored on the central operation panel 3 through the status confirmation. As a result, the central operation panel 3 can perform the rotation operation and the water discharge operation.

Thereafter, when the central operation panel 3 is rotated by the processing center personnel (step Sb7), the rotation signal is transmitted to the nozzle unit 4 (step Sb8). When the nozzle unit 4 receives the rotation signal, the water discharge part 41 is rotated in the direction indicated by the signal (step Sb9).

Thereafter, the central operation panel 3 starts the fire extinguishing pump (step Sb11) when the water discharge operation is performed by the processing center personnel (step Sb10). In addition, a water discharge start signal is transmitted to the nozzle unit 4 (step Sb12). At this time, if the central operation panel 3 cannot confirm the ACK from its nozzle unit 4, it will retry. If confirmation cannot be obtained even after retrying, the operation is terminated.

When the nozzle unit 4 receives the water discharge start signal, it transmits the signal to the on-site control panel 5 (step Sb13). When the on-site control panel 5 receives the water discharge start signal, it 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 starting valve is released, when the on-site control panel 5 receives the ON signal from the pressure switch provided on the secondary side of the starting valve (step Sb15), it transmits a water discharge signal indicating the start of water discharge to the nozzle unit 4 (step Sb15). Sb16). When the nozzle unit 4 receives the water discharge signal, it updates the status information of the machine from "OK" to "Water Discharge" (step Sb17). The above are instructions for manual fire extinguishing mode.

Next, FIG. 29 shows another sequence chart in the manual fire extinguishing mode. The manual fire extinguishing mode shown in this figure assumes that water discharge is started based on the operation of the field operation unit 6 connected to the field control panel 5 .

In the central operation panel 3, after the nozzle unit 4 most suitable for discharging water is selected (step Sa7), when the processing center personnel performs an operation to obtain the operation authority for the on-site operation unit 6 (step Sc1), the on-site control panel 5 The operation request signal is transmitted to the nozzle unit 4 (step Sc2). At this time, if the on-site control panel 5 cannot confirm the ACK from its nozzle unit 4, it will retry. If confirmation cannot be obtained even after retrying, the operation is terminated. When the nozzle unit 4 receives its operation request signal, it updates the operation right information of the machine to the "on-site control panel" (step Sc3). This update of the operation authority information is also reflected in the operation authority information stored on the field control panel 5 through status confirmation. As a result, the water discharge preparation operation becomes possible in the on-site operation unit 6.

After that, when the processing center personnel performs the water discharge preparation operation on the on-site operation unit 6 (step Sc4), the on-site control panel 5 transmits the water discharge preparation signal to the nozzle unit 4 (step Sc5). At this time, if the on-site control panel 5 cannot confirm the ACK from its nozzle unit 4, it will retry. If confirmation cannot be obtained even after retrying, the operation is terminated. When the nozzle unit 4 receives its water discharge preparation signal, it updates the status information of the machine from "confirmed" to "prepared" (step Sc6). The update of the status information is also reflected in the status information stored on the field control panel 5 through the status confirmation. As a result, the on-site operation unit 6 can perform the rotation operation and the water discharge operation.

Afterwards, when the processing center personnel performs a rotation operation on the on-site operation unit 6 (step Sc7), the on-site control panel 5 transmits the rotation signal to the nozzle unit 4 (step Sc8). When the nozzle unit 4 receives the rotation signal, the water discharge part 41 is rotated in the direction indicated by the signal (step Sc9).

Afterwards, when the processing center personnel performs a water discharge operation on the on-site operation unit 6 (step Sc10), the on-site control panel 5 transmits a water discharge request signal to the nozzle unit 4 (step Sc11). At this time, if the on-site control panel 5 cannot confirm the ACK from its nozzle unit 4, it will retry. If confirmation cannot be obtained even after retrying, the operation is terminated.

When the nozzle unit 4 receives the water discharge request signal, it transmits the signal to the central operation panel 3 (step Sc12). When the central operating panel 3 receives the water discharge request signal, it starts the fire extinguishing pump (step Sc13). In addition, a water discharge start signal is transmitted to the nozzle unit 4 (step Sc14). When the nozzle unit 4 receives the water discharge start signal, it transmits the signal to the on-site control panel 5 (step Sc15). When the on-site control panel 5 receives the water discharge start signal, it 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 starting valve is released, when the on-site control panel 5 receives an ON signal from the pressure switch provided on the secondary side of the starting valve (step Sc17), it transmits a water discharge signal indicating the start of water discharge to the nozzle unit 4 (step Sc17). Sc18). When the nozzle unit 4 receives the water discharge signal, it updates the status information of the machine from "OK" to "Water Discharge" (step Sc19). The above are instructions for manual fire extinguishing mode.

1-2-3. Water release stop and recovery action Next, the water discharge stop and recovery operations will be described. Fig. 30 shows a sequence diagram of water discharge stop and recovery operations. The operation shown in this figure assumes that the water discharge is stopped and restored based on the operation of the central operation panel 3 .

The central operating panel 3 transmits a water discharge stop signal to the nozzle unit 4 (step Sd2) when the processing center personnel performs a water discharge stop operation (step Sd1). At this time, if the central operation panel 3 cannot confirm the ACK from its nozzle unit 4, it will retry. If confirmation cannot be obtained even after retrying, the operation is terminated. When the nozzle unit 4 receives its water discharge stop signal, it transmits the signal to the on-site control panel 5 (step Sd3). When the on-site control panel 5 receives the water discharge stop signal, it closes the start valve corresponding to the nozzle unit 4 (step Sd4). As a result, water discharge from the nozzle unit 4 is stopped.

After the starting valve is closed, when the field control panel 5 receives an OFF signal from the pressure switch provided on the secondary side of the starting valve (step Sd5), it transmits a stop signal indicating that the water discharge is stopped to the nozzle unit 4 (step Sd5). Sd6). When the nozzle unit 4 receives the stop signal, it updates the status information of the machine from "discharge water" to "confirm" (step Sd7).

After that, when the processing center personnel performs a full restoration operation (step Sd8), the central operation panel 3 transmits the operation request signal to the nozzle unit 4 (step Sd9). At this time, if the central operation panel 3 cannot confirm the ACK from its nozzle unit 4, it will retry. If confirmation cannot be obtained even after retrying, the operation is terminated. When the nozzle unit 4 receives its operation request signal, it updates the operation right information of the machine to "open" (step Sd10). The so-called "open" here means that the operation right does not exist in the central operation panel 3 and the on-site control panel 5. In addition, the nozzle unit 4 performs the restoration operation (step Sd11), and when the restoration operation is completed, the status information of the machine is updated from "confirmed" to "stored".

Thereafter, the central operation panel 3 turns off the fire-extinguishing pump operation lamp Lp6 when performing a pump stop operation of the fire-extinguishing pump panel (not shown) (step Sd12). The above is an explanation of the water discharge stop and recovery actions.

Next, FIG. 31 shows another sequence diagram of the water discharge stop and recovery operation. The operation shown in this figure assumes that the water discharge is stopped and restored based on the operation of the field operation unit 6 connected to the field control panel 5 .

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

After the priming valve is closed, when the on-site control panel 5 receives an OFF signal from the pressure switch provided on the secondary side of the priming valve (step Se7), it transmits a stop signal indicating that the water discharge is stopped to the nozzle unit 4 (step Se7). Se8). When the nozzle unit 4 receives the stop signal, it updates the status information of the machine from "discharge water" to "confirm" (step Se9).

After that, when the processing center personnel performs the restoration operation on the on-site operation unit 6 (step Se10), the on-site control panel 5 transmits the operation request signal to the nozzle unit 4 (step Se11). At this time, if the on-site control panel 5 cannot confirm the ACK from its nozzle unit 4, it will retry. If confirmation cannot be obtained even after retrying, the operation is terminated. When the nozzle unit 4 receives its operation request signal, it updates the operation right information of the machine to "open" (step Se12). In addition, the restoration operation (step Se13) is performed. When the restoration operation is completed, the status information of the local machine is updated from "Confirm" to "Storage".

Thereafter, the central operation panel 3 turns off the fire extinguishing pump operation lamp Lp6 when the processing center personnel performs the pump stop operation of the fire extinguishing pump panel (step Se14). The above is an explanation of the water discharge stop and recovery actions.

In addition, in the above-mentioned water discharge stop and recovery operation, although the central operation panel 3 outputs a water discharge stop signal, the nozzle unit 4 may output a water discharge stop signal instead of the central operation panel 3 . At this time, 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 .

2. Modifications of the first embodiment The above-described first embodiment may be modified as follows. In addition, the following modifications can also be combined with each other.

2-1. Modification 1 The sensing unit 42 of the nozzle unit 4 is composed of the infrared linear sensor 421 and the flame detector 422 as described above. However, this structure is just an example. As long as it can detect and detect fire sources, it can also be composed of other sensors.

2-2. Modification 2 Auxiliary sensors may also be included in the fire extinguishing system 1 . The auxiliary sensor referred to here refers to a terminal device including the sensing unit 42 of the nozzle unit 4, the control unit 43, and the signal relay unit 44. In other words, it is the nozzle unit 4 which does not have the water discharge part 41. This auxiliary sensor is installed in the high-ceiling part of building B.

The auxiliary sensor and the nozzle unit 4 are also communicably connected to the central operating panel 3 via the annular wiring L2. In addition, it is connected to the field control panel 5 via a ring-shaped wiring L3 so as to be able to communicate with it.

This auxiliary sensor operates in the following manner in the above-mentioned automatic fire extinguishing mode. First, when the central operation panel 3 receives the sensor alarm signal from the fire receiver, it defines the nozzle unit 4 installed in the warning area of the sensor after the alarm. Then, a detection start signal is sent to the defined nozzle unit 4 and the auxiliary sensor.

The auxiliary sensor starts the fire source detection when receiving the detection start signal. Furthermore, when the fire source is detected as a result of the fire source detection, a fire source position signal indicating the rotation angle at the time of fire source detection is transmitted to the central operation panel 3 .

The central operating panel 3 receives the fire source position signals from all the nozzle units 4 and auxiliary sensors in the fire area, or when a predetermined time elapses from the first report of the fire source position signal, the central operation panel 3 responds based on the received fire source position signals. Based on the fire source position signal, the nozzle unit 4 that is most suitable for discharging water is selected. In this way, the fire source position signal transmitted from the auxiliary sensor is used to select the nozzle unit 4 most suitable for discharging water and is referred to.

In addition, when the fire extinguishing system 1 includes an auxiliary sensor, the fire extinguishing system 1 may include a nozzle unit 4 (in other words, a water gun) that does not include the sensing unit 42 . This water gun is an example of a fire extinguishing device.

The water discharge gun and the nozzle unit 4 are also communicably connected to the central operating panel 3 via the annular wiring L2. In addition, it is connected to the field control panel 5 via a ring-shaped wiring L3 so as to be able to communicate with it. Unlike the nozzle unit 4, this water gun does not include the sensing unit 42. Therefore, in the state of the water gun, fire source detection and contamination are not included in the fire source detection.

2-3. Modification 3 The center operation panel 3 includes a touch screen 33 as a display unit and an operation unit. In other words, the center operation panel 3 includes a display and a touch panel. Instead of the touch panel, another operating unit such as hard keys may be provided.

2-4. Modification 4 The second main screen shown in FIG. 7 shows the nozzle unit 4 in which the water is released, the fire source is being determined, or an abnormality is occurring. However, the second main screen shown in this figure is just an example, and other events may be displayed for the nozzle unit 4 . For example, the nozzle unit 4 in fire source detection may be shown.

2-5. Modification 5 The method of selecting the main screen on the central operation panel 3 is not limited to the method of using the above-mentioned menu list. For example, each of the first to third home screens may be provided with a display switching button, and each time the display switching button is pressed, the home screens are switched sequentially.

2-6. Modification 6 On the central operation panel 3, the number of selectable main screens is not limited to three. Only two of the above-mentioned first to third home screens may be selected as selection objects, or home screens different from these may be further added as selection objects.

2-7. Modification 7 The operation screens shown in FIGS. 13 and 22 show the rotation angle of the nozzle unit 4 on the display unit. However, the rotation angle can also be displayed in other ways. For example, the rotation angle is represented by changing the orientation of the nozzle of the nozzle image P1 or P3. Or you can also use a numerical value to represent the rotation angle.

2-8. Modification 8 The on-site operation unit 6 includes a touch screen 62 as a display unit and an operation unit. In other words, the field operation unit 6 includes a display and a touch panel. Instead of the touch panel, another operating unit such as hard keys may be provided.

2-9. Modification 9 The sensor of the automatic fire alarm device 2 is not limited to the analog type, and may also be a sensor with a fixed sensitivity. In addition, the fire receiver is not limited to R type, and may also be P type.

2-10. Modification 10 The on-site operation unit 6 can communicate with the on-site control panel 5 through wireless communication instead of wired connection.

3. Second embodiment 3-1.Composition The fire extinguishing system 10 according to the second embodiment of the present invention will be described with reference to the drawings.

The sprinkler control panel 14 shown in this figure includes a control unit 141, a memory unit 142, a touch screen 143, and a communication unit 144. Among these components, the storage unit 142 stores status information of the fixed head 17 . Specifically, the protection area and the water discharge state provided for each fixed head 17 are memorized.

The control unit 141 is composed of a processor and a memory. The processor implements various functions by executing programs stored in the memory. Among the functions implemented, as shown in FIG. 33 , they include a water discharge control unit 1411, a display control unit 1412, and a signal transmission unit 1413.

3-2-1. Automatic water release mode Figures 40 and 41 show a program chart of the automatic water discharge mode. There is a fire in building C. When the smoke sensor 11 detects the fire, it transmits the fire signal to the fire receiver 12 . When the fire receiver 12 receives the fire signal, it forwards it to the sprinkler control panel 14 . The sprinkler control panel 14 receives the transfer (step Sf1), and lights up the automatic fire notification lamp Lp11 of the protection area where the fire occurred on the operation screen (step Sf2). In addition, the automatic fire notification light lighting signal is transmitted to the on-site control panel 15 (step Sf3). When the on-site control panel 15 receives the lighting signal of the automatic fire notification lamp, it sets the automatic fire notification lamp flag of the protection area where the fire occurs to ON (step Sf4). As a result, when the field operation unit 16 is connected to the field control panel 15, the field operation unit 16 lights the automatic fire notification lamp Lp18 of the protection area where the fire occurs on the operation screen.

Afterwards, when the flame sensor 13 detects a fire, the flame sensor 13 transmits the fire signal to the sprinkler control panel 14 . When the sprinkler control panel 14 receives the fire signal (step Sf5), the fire extinguishing special lamp Lp12 of the protective area where the fire occurs is turned on on the operation screen (step Sf6). In addition, the lighting signal of the special fire extinguishing lamp is transmitted to the on-site control panel 15 (step Sf7). When the on-site control panel 15 receives the lighting signal of its special fire-extinguishing lamp, it sets the special fire-extinguishing lamp mark of the protection area where the fire occurs to ON (step Sf8). As a result, when the field operation unit 16 is connected to the field control panel 15, the field operation unit 16 lights the fire extinguishing lamp Lp19 of the protection area where the fire occurs on the operation screen.

The sprinkler control panel 14 determines that a fire has occurred when the smoke sensor 11 and the flame sensor 13 installed in the same protective area sound an alarm (step Sf9). Then, the area lamp Lp10 and the fire lamp Lp9 of the protection area where the fire occurs are turned on on the operation screen (step Sf10). In addition, the water discharge is started and the countdown of the timer is started (step Sf11), the timer operating lamp Lp14 is flashed on the operation screen, and the remaining time is displayed in the remaining time display area D (step Sf12). Furthermore, lighting signals such as area lights are transmitted to the on-site control panel 15 (step Sf13). When the on-site control panel 15 receives a lighting signal such as the area lamp, it sets the area lamp mark, fire lamp mark, timer operation lamp mark, and operation possible lamp mark of the protection area where the fire occurs to ON (step Sf14). As a result, when the field control panel 15 is connected to the field operation unit 16, the field operation unit 16 lights up the area lamp Lp17, the fire lamp Lp16, and the operation possible lamp Lp20 in the protection area where the fire occurs on the operation screen, and activates the timer. Lamp Lp22 flashes.

After that, when the countdown of the water discharge start timer ends (step Sf15), the sprinkler control panel 14 opens the remote operation valve 18 of the fire protection area and transmits the pump start signal to the pump control panel 20 (step Sf16). ). As a result, water is discharged from the fixed head 17 in the fire protection area. When the sprinkler control panel 14 receives an ON signal from the pressure switch (not shown) as a result of the water discharge, it turns on the water discharge lamp Lp15 on the operation screen (step Sf17). In addition, the water lamp lighting signal is transmitted to the on-site control panel 15 (step Sf18). When the on-site control panel 15 receives the water discharge lamp lighting signal, it sets the water discharge lamp flag to ON and the timer operation light flag to OFF (step Sf19). As a result, when the field operation unit 16 is connected to the field control panel 15, the field operation unit 16 lights the water discharge lamp Lp23 and turns off the timer operation lamp Lp22 on the operation screen.

Afterwards, when the disaster prevention personnel confirms that the fire is extinguished and presses the water discharge stop button Bt5 of the sprinkler control panel 14 (step Sf20), the sprinkler control panel 14 closes the remote operation valve 18 opened in step Sf16 (step Sf21). As a result, water discharge from the fixed head 17 is stopped. When the sprinkler control panel 14 receives an OFF signal from the pressure switch as a result of the water discharge, it turns off the water discharge lamp Lp15 on the operation screen (step Sf22). In addition, the water lamp extinguishing signal is transmitted to the on-site control panel 15 (step Sf23). When the on-site control panel 15 receives the signal to turn off the water lamp, it sets the water lamp flag to OFF (step Sf24). As a result, when the field operation unit 16 is connected to the field control panel 15, the field operation unit 16 turns off the water lamp Lp23 on the operation screen.

Afterwards, when the disaster prevention personnel presses the reset button Bt6 of the sprinkler control panel 14 (step Sf25), the sprinkler control panel 14 turns on the area lights Lp10, automatic fire notification lights Lp11 and fire extinguishing special lights Lp12 of all the protective areas on the operation screen. turns off (step Sf26). In addition, a signal to turn off the area lights and the like is sent to the on-site control panel 15 (step Sf27). When the on-site control panel 15 receives the signal to turn off the area lights, etc., it sets the area light marks, automatic fire notification light marks, and fire extinguishing special light marks of all protective areas to OFF (step Sf28). As a result, when the field operation unit 16 is connected to the field control panel 15, the field operation unit 16 turns off the area lamps Lp17, automatic fire notification lamps Lp18, and fire extinguishing special lamps Lp19 of all the protection areas on the operation screen. The above are instructions for the automatic water release mode.

In addition, in the above-mentioned automatic water discharge mode, disaster prevention personnel conduct on-site confirmation and when it is judged that it is not a fire alarm, they can also stop the countdown of the water discharge start timer. As for the method of stopping the countdown, there are a method of operating the mode selection button Bt1 of the sprinkler control panel 14, a method of switching the water discharge mode to a manual water discharge mode, and a method of pressing the timer stop button Bt8 of the on-site operation unit 16. of 2. Among the two methods, the latter method is that when the timer stop button Bt8 of the field operation unit 16 is pressed, the field control panel 15 transmits the timer stop signal to the sprinkler control panel 14 . When the sprinkler control panel 14 receives its timer stop signal, it stops the countdown.

Furthermore, in the above description, the sprinkler control panel 14 is used to instruct the water discharge stop. However, the on-site operation unit 16 may be used instead of the sprinkler control panel 14 to instruct the water discharge stop. At this time, the disaster prevention personnel presses the water discharge stop button Bt11 of the on-site operation unit 16. The on-site control panel 15 receives this operation and transmits the water discharge stop signal to the sprinkler control panel 14. When the sprinkler control panel 14 receives its water discharge stop signal, it closes the remote operation valve 18 opened in step Sf16. As a result, water discharge from the fixed head 17 is stopped.

3-2-2. Manual water release mode Figures 42 and 43 show a program chart of the manual water discharge mode. Among the steps shown in the figures, steps Sf1 to Sf10 are common to the automatic water discharge mode, so their description is omitted.

After the execution of step Sf10, the sprinkler control panel 14 transmits a lighting signal such as an area lamp to the on-site control panel 15 (step Sg1). When the on-site control panel 15 receives the lighting signal of its area lamp and the like, it sets the area lamp mark, the fire lamp mark, and the operation possible lamp mark of the protection area where the fire occurs to ON (step Sg2). As a result, when the field operation unit 16 is connected to the field control panel 15, the field operation unit 16 lights the area lamp Lp17, the fire lamp Lp16, and the operation possible lamp Lp20 of the protection area where the fire occurs on the operation screen.

Afterwards, disaster prevention personnel conducted on-site confirmation and when the occurrence of fire was confirmed, they were instructed to manually release water. Specifically, on the sprinkler control panel 14, the water discharge area selection button Bt3 for the protection area where the fire occurs is pressed, and then the water discharge start button Bt4 is pressed. When receiving these operations (step Sg3), the sprinkler control panel 14 opens the remote operation valve 18 of the selected protection area and transmits the 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 protection area. When the sprinkler control panel 14 receives an ON signal from the pressure switch (not shown) as a result of the water discharge, it turns on the water discharge lamp Lp15 on the operation screen (step Sg5). In addition, the water lamp lighting signal is transmitted to the on-site control panel 15 (step Sg6). When the on-site control panel 15 receives the lighting signal of the water lamp, it sets the water lamp flag to ON (step Sg7). As a result, when the field operation unit 16 is connected to the field control panel 15, the field operation unit 16 lights the water discharge lamp Lp23 on the operation screen.

Since the subsequent steps Sf20 to Sf28 are common to the automatic water discharge mode, their description is omitted. The above are instructions for manual water release mode.

In addition, in the above description, although the sprinkler control panel 14 is used to instruct manual water discharge, the on-site operation unit 16 may be used instead of the sprinkler control panel 14 to instruct manual water discharge. At this time, the disaster prevention personnel presses the water discharge area selection button Bt9 of the protection area where the fire occurs on the on-site operation unit 16, and then presses the water discharge start button Bt10. The on-site control panel 15 receives these operations and transmits the water discharge start signal to the sprinkler control panel 14. When the sprinkler control panel 14 receives its water discharge start signal, it opens the remote operation valve 18 of the selected protection area and transmits the pump start signal to the pump control panel 20 . As a result, water is discharged from the fixed head 17 in the selected protection area.

Furthermore, in the above description, manual water discharge is instructed after the fire is confirmed. However, if the disaster prevention personnel discover the fire before the fire is confirmed, manual water discharge may be instructed before the fire is confirmed. However, when the on-site operation unit 16 is used to perform this instruction, before instructing manual water discharge, the operation availability selection button Bt7 must be operated to enable the panel operation of the on-site operation unit 16.

4. Modifications of the second embodiment The second embodiment described above may be modified as follows. In addition, the following modifications can also be combined with each other.

4-1. Modification 1 As far as the fire extinguishing device is concerned, a water gun can also be used instead of the fixed head 17.
