BACKGROUND OF THE INVENTION
The present invention relates to a simultaneous return control method for smoke prevention devices such as smoke exhausters and smoke outlets, and a smoke prevention device control system using the method.
[0002]
[Prior art]
Conventionally, in buildings and condominiums, disaster prevention receivers are installed in disaster prevention monitoring rooms and management rooms, and fire detectors are installed in each room, dwelling unit, floor, etc. to detect smoke concentration and ambient temperature, The occurrence of fire is monitored.
When the fire alarm is triggered, the disaster prevention receiver will notify the occurrence of the fire by the district sound device set in advance corresponding to the fire sensor and promptly evacuate people in the building. In addition to urging and controlling the smoke-exhaust equipment in the vicinity of the fire detector that has been reported, a smoke-exhaust section is formed in the building to prevent the spread of fire and the spread of smoke.
[0003]
Among the smoke control devices controlled in conjunction with this, there is a smoke exhaust duct consisting of a smoke exhauster and a smoke exhaust port, and when a fire detector is triggered, the disaster prevention receiver is connected to the smoke exhauster and the exhaust. The smoke vents are activated to discharge the smoke generated by the fire.
FIG. 7 is a diagram illustrating an example of a configuration of a conventional smoke control device.
The disaster prevention receiver 101 derives the multiplex transmission line L100, and smoke exhausters 103a, 103b,..., And smoke exhaust ports (dampers) 104a, as smoke prevention devices via the repeaters 102a, 102b,. 104b,... Are connected. Here, the smoke exhaust ports 104a, 104b,... Are opened and closed provided in the smoke exhaust ducts Da, Db,... (Ventilation path) connecting the smoke exhausters 103a, 103b,. It is a valve, and is controlled to open and close as the smoke exhausters 103a, 103b,.
[0004]
FIG. 8A shows the operation of the smoke exhaust ports 104a, 104b,... And the state when the smoke exhaust ports 104a, 104b,. ,... And the state when returning and returning to the localization are shown. According to this example, in the system shown in FIG. 7, each of the smoke exhaust ports 104a and 104b and the smoke exhausters 103a and 103b shows an operating state.
[0005]
When receiving the fire signal from one of the fire detectors S connected via the multiplex transmission line L101, the disaster prevention receiver 101 sends an operation control signal to the smoke exhaust ports 104a and 104b corresponding to the fire detector S. Then, the opening control is performed, after which an operation control signal is sent to the smoke exhausters 103a and 103b to rotate the fan, and the smoke generated by the fire is discharged. And if the smoke is no longer needed because the fire is extinguished, etc., the disaster prevention receiver 101 (relay device 102a, 102b) having a return control function can go to the place where each smoke prevention device is installed and return manually. , A return control signal is sent to each smoke prevention device (smoke exhaust devices 103a and 103b, smoke exhaust ports 104a and 104b), and each is returned to a normal position.
[0006]
FIG. 9 is an example of a screen displayed on the disaster prevention receiver 101 during the return control. Here, the return control is performed in the order of the smoke exhauster 103a (1), the smoke exhauster 103b (2), the smoke exhaust port 104a (3), and the smoke exhaust port 104b (4). (See FIG. 7).
[0007]
[Problems to be solved by the invention]
However, in the above conventional smoke control device control system, it is necessary to designate the smoke control device one by one even when each smoke control device is returned by sending a return control signal from the disaster prevention receiver. The operation was particularly troublesome when there were many smoke control devices to be restored.
[0008]
In addition, as shown in FIG. 10, if the smoke exhaust port is returned while the smoke exhauster is operating, the air pressure in the smoke exhaust duct becomes too high (vacuum state), and the smoke exhaust duct may be damaged. Therefore, it was necessary to operate the disaster prevention receiver while considering the order of smoke prevention equipment to be restored.

DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 is a view showing an example of the configuration of the smoke-proof / fume-control device control system of the present invention.
A disaster prevention receiver 1 is installed in a disaster prevention monitoring room or a management room of a building or a condominium, etc., while a plurality of repeaters 2a, 2b,... Are provided on the multiplex transmission line L1 derived from the disaster prevention receiver 1. Further, each of the repeaters 2a, 2b,... Is connected to each of the repeaters 2a, 2b,..., And smoke exhausters 3a, 3b,. ... and connected. Further, a fire detector S installed in each room, dwelling unit, floor, or the like is connected to the multiplex transmission line L2 derived from the disaster prevention receiver 1.
[0015]
In addition to the illustration, the disaster prevention receiver 1 includes a gas leak alarm, various alarm devices for detecting abnormality of the fire pump, district sound devices, smoke exhausters 3a, 3b,. Disaster prevention terminals such as smoke prevention devices (automatic closing device, fire door, hanging wall, etc.) other than 4b,... Can be connected.
Based on the address information of each disaster prevention terminal such as the fire detector S, the disaster prevention receiver 1 monitors operation abnormality, line disconnection, and the like by polling through the multiple transmission line L2. In such a state, when a fire signal is received from any of the fire detectors S through the multiplex transmission line L2, an indicator lamp (not shown) indicating the operation of the fire detector S is turned on or blinked to generate a notification. The district window (not shown) corresponding to the installation location of the fire detector S is turned on or blinked, and an alarm sound is output from the built-in acoustic device (not shown). Then, an alarm is output from a district sound device (not shown) set in advance corresponding to the fire detector S.
[0016]
Further, the disaster prevention receiver 1 sends an operation control signal to the repeaters 2a and 2b (smoke prevention and repeater), and responds to the fire detector S that is notified by each repeater 2a and 2b. The set smoke exhaust ports 4a and 4b are controlled to open, and then an operation control signal is sent to the smoke exhausters 3a and 3b to rotate the fan and discharge smoke generated by the fire. FIG. 1 shows a state where the smoke exhaust ports 4a and 4b and the smoke exhausters 3a and 3b are operating (see FIG. 8).
[0017]
When the fire is extinguished and the smoke is no longer necessary, a return control signal is sent in the order of the smoke exhausters 3a and 3b and the smoke exhaust ports 4a and 4b that are in operation, and each is returned to a normal position. In the present invention, the return control can be performed all at once.
For the simultaneous return control, the disaster prevention receiver 1 associates each smoke prevention device (smoke exhaust devices 3a and 3b, smoke exhaust ports 4a and 4b) with a group type such as a building, a floor, and a device type. When one smoke control device is selected and an operation to instruct the simultaneous return of smoke control device is performed, the smoke control device belonging to the group type of the selected smoke control device is selected. Then, a return control signal is sequentially sent through the multiplex transmission line L1 to return each smoke evacuation device.
[0018]
FIG. 2 shows an example of the screen display of the disaster prevention receiver 1, and as shown in (a), the operation control signal is sent to the smoke-proof device (smoke-exhaust devices 3a and 3b, smoke-exhaust ports 4a and 4b). When the smoke exhauster 3a of “one building 1st floor 1” is selected and a simultaneous return operation is performed ((1)) as shown in FIG. As shown in the figure, the smoke evacuator 3b having the same installation location “1 building 1st floor” and the same device type “smoke evacuator” is also returned in the same manner. In addition, when the smoke exhaust port 4a of “1 building 1st floor 1” is selected and a simultaneous return operation is performed ((2)), the installation location is the same on “1 building 1st floor” and the device type is “ The same smoke exhauster 4b at the “smoke exhaust port” is also returned in the same manner.
[0019]
By returning in this way, the disaster prevention receiver 1 can return a plurality of smoke prevention devices by one remote operation. In particular, when there are many smoke control devices to be restored, the number of operations is greatly reduced, and operation mistakes are eliminated. In the example of FIG. 1 and FIG. 2, what was conventionally required four times of operation is only required to be performed twice.
Here, one smoke prevention device is selected and the simultaneous return of smoke prevention devices belonging to the same group is instructed. However, the present invention is not limited to this. In the disaster prevention receiver, A group type such as a floor and a device type may be directly designated, and a return control signal may be sequentially transmitted to the smoke control devices belonging to the group type to return each smoke control device.
[0020]
Moreover, although the case where the smoke exhausters 3a and 3b and the smoke exhaust ports 4a and 4b are returned as the smoke prevention device has been described above, the present invention is not limited to this, and other return such as an automatic closing device is performed. Similarly, smoke-proof smoke exhaust devices can be restored simultaneously.
Next, the internal configuration of the disaster prevention receiver 1 is shown in a block diagram in FIG.
In the figure, 10 is composed of a CPU and the like, and is a control means for controlling other means of the disaster prevention receiver 1, and 11 is for controlling multiplex transmission with the repeaters 2a and 2b through the multiplex transmission line L1 and multiplex transmission. Multiplex transmission means for controlling multiplex transmission with the fire detector S through the line L2, 12 an operation means constituted by various switches, 13 a display means constituted by a CRT or a liquid crystal screen, and 14 a fire detector S is a storage means that stores an interlocking table or the like that stores S and the smoke-exhaust / exhaust device associated therewith.
[0021]
The storage unit 14 of the disaster prevention receiver 1 stores each smoke-exhaust device in association with a group type such as a building, a floor, or a device type. When one smoke prevention device is selected by the operation of the cursor key, the simultaneous return switch, or the like, and an operation for instructing the simultaneous return of the smoke prevention device is performed, the storage unit 14 is referred to and the selected A smoke control device is returned to each of the smoke control devices by sequentially transmitting a return control signal to the active smoke control devices belonging to the group type of the smoke control device via the multiplex transmission line L1. 2).
[0022]
FIG. 4 schematically shows the configuration of the storage unit 14.
Here, each of the smoke control devices is classified and stored according to an address, a management unit such as an installation building, a floor, and a district, and a device type. For example, when “smoke exhausters” belonging to the group “1 building 1st floor” are to be returned all at once, the addresses “1001” and “1003” are designated from the disaster prevention receiver 1, and the return control signal is sequentially transmitted. Will be sent out. The illustrated configuration may be a part of an interlocking table that stores addresses and the like of smoke prevention devices that are linked to each fire detector S in correspondence with the addresses and the like of the fire detectors S.
[0023]
Next, another method for the simultaneous return of smoke-proof equipment will be described with reference to FIGS.
The disaster prevention receiver 1 stores the operation order of the smoke prevention devices (smoke exhaust devices 3a, 3b, smoke outlets 4a, 4b), and when an operation to instruct simultaneous return of the smoke prevention devices is performed. From the last activated smoke control device, a return control signal is sequentially sent to each smoke control device via the multiplex transmission line L1 in the reverse order of operation. Restore the device.
[0024]
FIG. 6 shows an example of the screen display of the disaster prevention receiver 1 in this case. In (a), the operation control is sequentially performed on the smoke prevention devices (the smoke exhausters 3a and 3b and the smoke exhaust ports 4a and 4b). Signals are sent and the operating status is displayed in chronological order. At the same time, such data is stored in the storage means 14. That is, when the disaster prevention receiver 1 receives the operation confirmation signal returned from the smoke prevention device that has received the operation control signal, the disaster prevention receiver 1 sequentially stores the operation status (operation order) of the smoke prevention device in the storage unit 14.
[0025]
In this state, as shown in FIG. 5 (b), when the smoke exhauster 3b of “one building 1st floor 2” is selected and a simultaneous return operation is performed, as shown in FIG. The return control is performed in the reverse order ((d) → (c) → (b) → (b)) in the operation sequence shown in a) ((b) → (b) → (c) → (d)). (▲ 1 ▼ → ▲ 2 ▼ → ▲ 3 ▼ → ▲ 4 ▼).
Accordingly, the order of return is not mistaken, and the smoke exhaust ports 4a and 4b corresponding to the smoke exhausters 3a and 3b can always be in operation (open state) while the smoke exhausters 3a and 3b are in operation. The ducts Da and Db are not damaged. In addition, a plurality of smoke prevention devices can be restored by a single operation.
[0026]
Here, one smoke prevention device is selected, and the smoke prevention device that was activated before the operation of the selected smoke prevention device is targeted for return control, but is not limited to this. If the simultaneous return switch of the operating means 12 is operated, all the smoke control devices that are operating at that time are returned from the smoke control device that was activated most recently in the reverse order of operation. Also good.
[0027]
In addition, the return order may be controlled in units of the smoke exhaust ducts Da and Db, such as the smoke exhauster 3b → the smoke exhaust port 4b → the smoke exhauster 3a → the smoke exhaust port 4a. Even if the smokers 3a and 3b receive the return control signal, the rotation of the fan cannot be stopped immediately. Therefore, if the smoke exhaust ports 4a and 4b are not closed after waiting until the fans stop, Since the ducts Da and Db remain to be damaged, it is necessary to restore them in consideration of this point.
[0028]
Thus, in order to perform the return control in the reverse order of the operation order, the disaster prevention receiver 1 stores the operation order of the smoke-proof device in the storage means 14, and the control means 10 includes the operation means. 12, when the operation of instructing the simultaneous return of the smoke prevention device is performed, the storage unit 14 is referred to and the respective smoke prevention devices are operated in the order reverse to the operation order from the smoke prevention device that was last activated. A return control signal is sequentially sent to the smoke device via the multiplex transmission line L1 (see FIG. 3).
[0029]
In addition, although the case where the smoke exhausters 3a and 3b and the smoke exhaust ports 4a and 4b are restored as the smoke prevention device has been described above, the present invention is not limited to this, and other restoration such as an automatic closing device is performed. Similarly, if there is a restriction on the return order, the smoke-proof device of the type can be returned all at once.
[0030]
【The invention's effect】
As can be understood from the above description, in the simultaneous return control method for smoke evacuation equipment according to claim 1 of the present invention, for the disaster prevention receiver, one smoke evacuation equipment is selected and the simultaneous return operation is performed. When this is done, a return control signal is sequentially sent to the smoke control devices belonging to the group type of the selected smoke control device to restore each smoke control device. Therefore, since a plurality of smoke prevention devices can be restored by a single operation, there is no need to select one smoke prevention device one by one as in the prior art, and the operation of return control is simplified.
[0032]
In the smoke-proof device control system according to claim 2, if each smoke-proof device is stored in the disaster prevention receiver in association with a group type such as a building, a floor, or a device type, the disaster prevention receiver is When one smoke control device is selected and the selected simultaneous return operation is performed, a return control signal is sequentially sent to the smoke control device belonging to the group type of the selected smoke control device. Thus, each smoke control device can be restored. Therefore, in the disaster prevention receiver, since a plurality of smoke prevention devices can be restored by a single operation, the operation of the return control becomes simpler than in the past.
