DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to an embodiment shown in the accompanying drawings. Embodiment 1 FIG. FIG. 1 is a schematic configuration diagram showing a first embodiment of a sprinkler fire extinguishing system according to the present invention. In FIG.
B1F, 1F, 2F, 3F, 4F,... Represent a plurality of floors of a building such as a building, for example, a ground floor, a first floor, a second floor, a third floor, and a fourth floor, respectively.
Represents the floor ... First, an automatic fire alarm system will be described. Reference numeral 1 denotes a fire detector, for example, a fire detector, which is provided in large numbers for each floor of a building. 2 is a common signal line electrically connected to all of these fire detectors 1;
Is a fire monitoring panel arranged in a disaster prevention center (not shown) on the first floor 1F for receiving a fire signal from the fire detector 1 via a common signal line 2, for example. In addition, equipment required as automatic fire alarm equipment such as a local sound apparatus is provided, but the description thereof is omitted here.

Next, the sprinkler fire extinguishing system (hereinafter, referred to as NS system) of the present invention will be described.
The NS system includes an automatic fire alarm system and a fast-acting sprinkler head (hereinafter referred to as NS head) having a high heat response speed in order to extinguish a fire early to minimize fire damage and water damage caused by fire extinguishing. This is a new sprinkler system used to extinguish a fire with a small amount of water in the early stage of a fire. In FIG. 1, reference numeral 6 denotes a water supply main pipe extending through a plurality of floors, and reference numeral 7 denotes a branch pipe branching from the water supply main pipe 6 and branching off for each floor. Numeral 8 denotes a large number of NS heads provided in each branch pipe 7, whose heat response speed is remarkably faster than that of a conventional sprinkler head (not shown) so that an initial fire can be detected and extinguished. Things. The idea of increasing the heat response speed is to improve the heat receiving efficiency and reduce the heat loss, in other words, to surely catch the heat of the fire without escaping it to another. Specifically, the NS head 8 has a standard water discharge pressure of 1 kg /
cm ² , flow rate 50 liters / min, floor area 2.
1 m ² per one installed, also need only installed per floor area 1.3 m ² is for restaurant small compartments, has a wider sprinkling area with less water discharge amount, to reduce the water spray density However, it can exhibit sufficient fire extinguishing ability. Further, a water source (not shown) and a pump unit 9 are provided near the lower end of the water supply main pipe 6.

Reference numeral 20 denotes a district valve device (hereinafter, referred to as an NS valve unit) provided between the water supply main pipe 6 and each branch pipe 7 to supply fire extinguishing water to a large number of NS heads 8. FIG. 5 will be described later in detail. Reference numeral 50 denotes a sprinkler repeater (hereinafter, referred to as an NS repeater) provided for each NS valve unit 20, and a corresponding NS
It is electrically connected to the valve unit 20 by the signal line 11, and will be described later in detail with reference to FIG. A fire monitoring panel (hereinafter, referred to as an NS monitoring panel) 80 is electrically connected to all the NS repeaters 50 by a common signal line 2, and will be described later in detail with reference to FIG.

The NS system according to the present invention is configured as described above. For example, a fire occurs on the second floor 2F, and at least one of the fire detectors 1 provided on the second floor 2F is activated. If a fire signal occurs,
This fire signal is sent to the NS monitoring panel 80 via the common signal line 2.
Transmitted to

The NS monitor panel 80 processes the received fire signal on a floor-by-floor basis, and then processes the fire signal via the common signal line 2 into the NS repeater 50 provided on the second floor 2F in this case. The NS repeater 50 transmits the start signal to the corresponding NS valve unit 20 via the signal line 11, thereby transmitting the NS signal.
The valve unit 20 is set in a standby state. The standby state of the NS valve unit 20 refers to a state in which the NS head 8 is opened so that water can be immediately sprayed from the NS head 8.
That is, the valve unit 20 is placed. Thereafter, when the NS head 8 opens due to the heat of the fire, the NS head 8
Pressurized fire-extinguishing water automatically adjusted to the set pressure starts to be discharged. Simultaneously with the start of the water discharge, the NS valve unit 20 transmits the coded flowing water signal to the NS repeater 50 via the signal line 11, and the NS repeater 50 transmits the flowing water signal together with its own address to a common signal line. N through 2
The water is transmitted to the S monitoring panel 80, whereby the water discharge warning is displayed on the NS monitoring panel 80. When the NS head 8 starts discharging water, the pump unit 9 (FIG. 1) is automatically activated, so that the fire extinguishing water flows from the water source through the pump unit 9, the water supply main pipe 6, the NS valve unit 20, and the branch pipe 7. Water is continuously discharged from the NS head 8.

FIG. 2 is a diagram showing an example in which all the transmission terminals such as the NS repeaters 50 are divided into a plurality of groups. In this example, the transmission terminals are connected to an NS monitoring panel 80 via a common signal line 2. Shown with respect to NS repeaters 50-B1F through 50-5F, group G1 comprises NS repeaters 50-B1F, etc., and group G2 comprises NS repeaters 50-1F and 50-5F.
-F, etc., and the group G3 is the NS repeater 50-3.
F and 50-4F etc., and group G4 is N
It comprises an S repeater 50-5F (not shown in FIG. 1) and the like.
As described above, the number of groups and the number of transmission terminals in each group can be arbitrarily determined.

The NS monitoring panel 80 includes an NS repeater 50-B1.
System polling, point polling, and selecting, which will be described later, are performed on transmission terminals such as F to 50-5F to collect predetermined information from predetermined transmission terminals and control predetermined transmission terminals.

Here, system polling does not mean, for example, polling each of the NS repeaters 50-B1F to 50-5F, but dividing the transmission terminals such as NS repeaters into four groups. Polling for each group, giving response timing for each group,
For example, polling in which a group having a transmission terminal that has detected a change in the state of the corresponding NS valve unit responds to the NS monitoring panel 80 at the time of the response. Point polling refers to polling only for a group that has responded to the NS monitoring panel 80 in system polling for each transmission terminal in the group, and assigns a response timing to each transmission terminal, for example, a transmission terminal that has detected a state change. The NS monitoring panel 8
Polling responding to 0. What is selecting?
It collects predetermined information from the transmission terminal responding to the NS monitoring panel 80 in point polling, and returns a predetermined control signal to the transmission terminal responding to the NS monitoring panel 80 in point polling.

FIG. 3 is a diagram for explaining an operation example of FIG.
The operation proceeds from the upper left to the upper right in FIG. 3, the operation proceeds from the right end to the left end of the next lower stage, and the processing sequentially proceeds in this manner. In FIG. 3, the upper part of the horizontal line indicates the operation of the NS monitoring panel 80, and the lower part of the horizontal line indicates the operation of the transmission terminal. In FIG. 3, a broken-line frame indicates that no response was made at the response timing, and a thick-line frame indicates that a response was made at the response timing. In other words, the thick line frame indicates a transmission terminal that has detected a state change (or a group having transmission terminals that have detected a state change) as compared to immediately before the response timing.

First, at P1 in FIG. 3, system polling is performed. That is, the NS monitoring panel 80 sends the address SPAD indicating system polling and the status information return instruction CM1 for returning status information to the groups G1 to G4, and then sequentially returns the timing for returning status information to the groups G1 to G4. ,give. Each of the groups G1 to G4 responds by returning state information and the like to the NS monitoring panel 80 at the time of its own response only when the transmission terminal in its group detects a state change. In the example shown in FIG. 3, only the group G2 responds to the NS monitoring panel 80 because the NS repeater 50-2F has detected a state change. As a result, the NS monitoring panel 80 sets the NS repeater 50-1F or 50-2 belonging to the group G2.
F and the like can detect a state change and know that they have state information to be sent to the NS monitoring panel 80.

Next, point polling is performed at P2. That is, the NS monitoring panel 80 sends the address GAD of the group to be polled and the status information return command CM1 to the transmission terminals belonging to that group. In the case of the above example, the address GAD (2) and the status information return instruction CM
1 to the transmission terminals of the group G2 including the NS repeaters 50-1F and 50-2F. Then, the timing for returning the state information is sequentially given to these transmission terminals.
Each transmission terminal responds by returning status information and the like to the NS monitoring panel 80 at its own response timing only when it has detected a status change. At the time of the point polling, the NS repeater 50-2F detects a state change, so that only the NS repeater 50-2F responds to the NS monitor panel 80. As a result, the NS monitoring panel 80
The NS repeater 50-2F detects a state change, and can grasp that the NS repeater 50-2F has state information to be sent to the NS monitoring panel 80.

Next, at P3, selecting is performed. That is, the NS monitoring panel 80 sets the address SAD (2F) of the transmission terminal that has issued the response signal and the status information return instruction CM
1 is sent. In the case of the above example, the NS repeater 50-2
Since the response signal was received from F, the NS monitoring panel 80
It sends out the address SAD (2F) of the S repeater 50-2F and the status information return command CM1. On the other hand, the NS repeater 50-2F sends the self address SAD (2F) and the data DA to be sent (for example, a secondary pressure decrease signal) to the NS monitoring panel 80.

When receiving the data DA, the NS monitoring panel 80 receives the address SAD (2F) and the received data DA.
The NS repeater 50-2F receives the data DA, collates the data DA transmitted immediately before by itself with the data DA received at that time, and if the two data match, the data DA is compared with the data DA. It is sent to the NS monitoring panel 80 again.
If the data DA received the first time and the data DA received the second time match, the NS monitoring panel 80 determines that the data DA transmitted by the NS
A is recognized. Then, the NS monitoring panel 80 performs necessary processing, for example, display or a simple alarm, based on the received data DA. In this example, the state information is collected from the NS repeater as the transmission terminal. However, a fire signal from a fire detector similarly connected as the transmission terminal is also collected. Thereafter, the state returns to the normal state, and the above system polling is repeated.

In the above example, the point polling and the selecting are performed twice each, in order to prevent erroneous transmission due to induced noise or the like.

Next, an operation of checking for a disconnection of the common signal line 2 will be described. In P01 of FIG. 3, system polling is performed once, and then selecting for checking the disconnection of the signal line 2 to the NS repeater 50-B1F is performed.
That is, the NS monitoring panel 80 sends the address SAD (B1F) of the NS repeater 50-B1F and the specific information return command CM2, and the NS repeater 50-B1F sends its own address SA.
D (B1F) and the specific information (in this case, the type information CL indicating the type of the NS repeater) are returned to the NS monitoring panel 80. Upon receiving the type information CL from the NS repeater 50-B1F, the NS monitoring panel 80 determines that there is no disconnection in the signal line 2 from the NS monitoring panel 80 to the NS repeater 50-B1F. After performing system polling once and confirming that there is no transmission terminal that has detected a state change,
The same disconnection test as above is performed on the NS repeater 50-1F. In this manner, for each of the transmission terminals such as the NS repeater 50, the disconnection inspection of the signal line 2 from the NS monitoring panel 80 to the transmission terminal is performed, and during that time, the system polling is executed once. In this system polling, if any group responds, of course, point polling is performed for that group,
Make the necessary selections.

The type state CL will not be described in detail except for the NS repeater, but there is information indicating a pump unit repeater, an auxiliary sprinkler repeater, and the like. As described above, if the NS monitoring panel 80 collects the type information as the specific information, the NS monitoring panel 80 changes the type of the NS repeater 50 simultaneously with the presence or absence of the connection of the NS relay 50. Can be known from the NS monitoring panel 80. In the example above,
Each time the system polling is performed once, the disconnection determination selecting is executed.
In order to monitor only 0-B1F to 50-5F, it is necessary to perform system polling 16 times. The disconnection determination may be performed every time the system polling is performed a predetermined number of times, or the disconnection determination may be performed every predetermined time.
Further, disconnection discrimination selecting of a plurality of NS repeaters 50 may be performed at one time. Also, the same NS repeater 50
On the other hand, if the disconnection determination selecting is performed twice consecutively, it is possible to prevent erroneous determination due to induction noise. The specific information may be information other than the type information, for example, a specific code.

FIG. 4 is a diagram showing an example in which devices other than these devices are connected to a common signal line connecting the NS monitoring panel, the fire detector, and the NS repeater. In FIG. The fire relay 13, the indicator 14, and the district bell device 15 are connected to the common signal line 2 (S + and S-).

FIG. 5 shows the N used in the first embodiment of the present invention.
FIG. 2 is a schematic configuration diagram illustrating an S valve unit 20. This N
The S-valve unit 20 is an automatic valve having both functions of a pre-operation type automatic alarm valve and an automatic valve with a secondary pressure adjusting function, and is installed for each floor of a building as described above. In FIG. 5, reference numeral 21 denotes an NS valve whose primary side 22 is connected to the above-described water supply main pipe 6 via a primary side pipe 23.
The secondary side 24 is connected to the NS head 8 via the secondary side pipe 25 and the branch pipe 7 described above. Although normally closed, fire detector 1 (Fig. 1)
The NS valve 21 which can be opened by an activation signal from the NS monitoring panel 80 in accordance with a fire signal from
An electric remote test valve 26 and a manual test valve 27 for testing the flow of water to the secondary pipe 25, and pressurized fire extinguishing water in the primary pipe 23 are adjusted to a predetermined pressure by adjusting the opening of the NS valve 21. A pressure-regulating pilot valve 28 that adjusts the pressure and supplies it to the secondary pipe 25, an electric start valve 29 that normally shuts off the pressurized release of the NS valve 21, and performs a shift operation to the above-described openable state, and Manual start valve 31 connected in parallel with this
And a pressure relief valve 32 for discharging abnormally high pressure in the secondary side pipe 25.

The NS valve 21 has a primary side 22 and a secondary side 2
4 is closed by a valve body 35 biased by a spring 34, and a piston 38 integral with the valve body 35 and a valve box 37 form a cylinder 38. The cylinder 38 is activated. It is connected to the pressure regulating pilot valve 28 via a valve 29 or a manually activated valve 31. The starting valve 29
Is opened and closed by a motor, an electromagnetic solenoid or the like connected to the terminal block 39 by an electric circuit shown by a broken line.

The pressure regulating pilot valve 28 is connected to the secondary pipe 25.
Is introduced into the operation room 28a by a pipe 25a, and the primary pressure is taken in from a primary side 22 of the NS valve 21 through a strainer (garbage remover) 41 and a pipe 22a, and a pressure adjusting action of the flam 28b and the spring 28c. Valve body 2
8d is adjusted, and the NS valve 2 is connected through the pipe 22b.
The primary pressure is introduced into one cylinder 38.

This pressure regulating pilot valve 28 is used for N
It has a function to open the S valve 21. That is, when the secondary pressure in the secondary pipe 25 introduced into the operation chamber 28a by the pipe 25a is lower than a predetermined pressure, the valve body 28d is opened by the pressure regulating action of the flam 28b and the spring 28c, and the pipe is opened. The primary pressure is gradually introduced into the cylinder 38 via the activated start valve 29 or the manually operated start valve 31 and the piston 36 is pushed up (to the left in the drawing), and the associated valve body 35 is activated. Is released, and the fire extinguishing water flows from the primary side 22 to the secondary side 24. Conversely, when the secondary pressure is higher than the predetermined pressure, the flam 28b
And the spring 28c regulates the valve body 28d by the pressure regulating action,
The inflow of the primary pressure is reduced, the pressure in the cylinder 38 is reduced, and the piston 36 is lowered (to the right in the drawing), and the interlocking valve element 35 is closed, so that the primary side 22 to the secondary side 24 is closed. The flow of fire-extinguishing water decreases, and this operation is repeated to
5 maintains a predetermined opening degree.

The opening degree of the NS valve 21 is adjusted in this manner, and the secondary pressure is adjusted to a predetermined pressure suitable for the fire extinguishing operation, for example, to 3.5 kg / cm ² near the secondary side 24. The operation chamber 28a of the pressure control pilot valve 28 is connected to the secondary pipe 25 via a pipe 25a via a small hole 28e of a piston portion of a valve body 28d opened for pressure control. As a result, the pressure in the secondary pipe 25 is increased at the time of the opening operation of the pressure control pilot valve 28, so that the pressure is constantly maintained at a predetermined pressure by the pressure control action of the pressure control pilot valve 28.
5. Replenish a small amount of primary pressure when the pressure drops due to a temperature change or the like. At this time, the NS valve 21 is not opened, so that no running water signal is generated. At the same time, the pressure flows into the back surface via the piston 36, and the sliding of the valve body 35 becomes slow, so that there is an effect that the pressure adjusting operation is easily performed.

Therefore, when the NS head 8 (FIG. 1) is opened due to the occurrence of a fire, it is possible to immediately discharge water at a predetermined pressure suitable for fire-extinguishing activities.
The NS valve 2 is controlled by the pressure control operation of the pressure control pilot valve 28.
1 is opened, and the opening degree of the valve body 35 is adjusted, so that fire-extinguishing water having a predetermined pressure suitable for fire-extinguishing activities is supplied to the secondary pipe 25.

The remote test valve 26 and the manual test valve 27 are NS
The secondary side 24 of the valve 21 and the drain pipe 42 are connected in parallel with each other. The remote test valve 26 is opened and closed by an electric unit 26a such as a motor or an electromagnetic solenoid connected to the terminal block 39 by an electric circuit shown by a broken line, and fire water of the same amount as one NS head 8 is drained by the opening operation. The size of the opening portion is set so as to be adjusted. The size of the opening of the manual test valve 27 is set so that the amount of fire extinguishing water equivalent to at least one of the NS heads 8 is drained by the opening operation thereof.
It is confirmed whether or not the water pressure in the secondary pipe 25 at the time of the drainage test is maintained at a predetermined pressure by the pointer of the pressure gauge 43 provided in the apparatus.

When the fire-extinguishing water introduced into the inside from the secondary side 24 exceeds an allowable pressure (a value slightly higher than a predetermined pressure), the exhaust-pressure valve 32 drains the fire-extinguishing water to the drain pipe 42, and discharges the secondary-side piping. The pressure in 25 is maintained within a predetermined range. As described above, the secondary pressure is measured by the pressure gauge 43, while the primary pressure of the fire extinguishing water in the primary pipe 23 is measured by the pressure gauge 44 connected to the strainer 41.

A pressure switch 45 for detecting the opening of the NS valve 21 is formed in a valve seat 33 of the NS valve 21 and is connected to a pipe from a flowing water detection chamber 46 which is closed by the valve body 35 when the valve body 35 is closed. A running water signal is supplied to the terminal block 39 via an electric circuit shown by a broken line. The pipe 22c is connected to the drain pipe 42 via the orifice 47, and when the NS valve 21 is closed, the fire extinguishing water that has operated the pressure switch 45 is gradually drained. The pressure switch 48 for detecting a large pressure reduction due to breakage of the secondary side piping system, etc.
, And supplies a secondary pressure drop signal to the terminal block 39 through an electric line shown by a broken line. Therefore, this pressure switch 4
8, when the NS head 8 is opened for any reason other than a fire, for example, detects a pressure drop in the secondary side pipe 25 and supplies a secondary pressure drop signal to the terminal block 39. 8 can be warned.

Next, the operation of the NS valve unit 20 will be described in detail. As described above, a start signal provided from the NS monitoring panel 80 and eventually from the NS repeater 50 via the terminal block 39 of the corresponding NS valve unit 20 operates the electric unit 29a to open the start valve 29 as described above. The standby state of the NS valve 21 can be confirmed by operating a limit switch (not shown) provided at the start valve 29 and closed at the fully open position, and the primary side 22 of the NS valve 21 can be confirmed from the water supply main pipe 6 through the primary pipe 23 of the NS valve 21. The fire extinguishing water that has been introduced to the secondary side 24 along with the opening of the NS head 8 (FIG. 1)
After the pressure is regulated by the pressure regulating pilot valve 28 in accordance with the pressure reduction of
8, the piston 36 moves the valve body 35 to the valve seat 33
The fire extinguishing water on the primary side 22 is gradually introduced into the secondary side 24 and eventually into the secondary side pipe 25.
The pressure switch 45 is operated by the rise of the water pressure in the pipe 22c to notify the terminal block 39 that the NS valve 21 has been opened. Thereafter, the introduction of the fire extinguishing water to the secondary pipe 25 is controlled by the above-described pressure adjusting operation of the pressure adjusting pilot valve 28, and the fire extinguishing water is reduced to a predetermined pressure.

Thereafter, when the water discharge from the NS head 8 (FIG. 1) continues, this large water discharge amount is detected by a pressure air tank or the like (not shown), and the pump unit 9 (FIG. 1) is activated to supply water. NS valve 2 from main pipe 6 (Fig. 1)
The high pressure fire extinguishing water is supplied to one primary side pipe 23. As described above, since the fire-extinguishing water of a predetermined pressure is filled in the secondary pipe 25 to the NS head 8 and the like, the fire-extinguishing water is discharged simultaneously with the opening of the NS head 8, and there is no delay in the fire-extinguishing activity.

FIG. 6 shows N used in the first embodiment of the present invention.
It is a wiring diagram which shows S repeater 50 in a partial block diagram. The NS repeater 50 is a transmission terminal of the NS monitor panel 80, and is electrically connected to the NS valve unit 20, which is an input / output device of the NS system, and is also electrically connected to the NS monitor panel 80. . The NS repeater 50 further includes:
When the state of the NS valve unit 20 is detected and the detected state is transmitted as an encoded information signal to the NS monitor panel 80 together with its own address, and when a coded control signal is transmitted to and received from the NS monitor panel 80, the address Then, the control signal is analyzed to control (start and return) the NS valve unit 20 after determining whether the command is a command to the self.
