[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to an automatic fire alarm system installed in an apartment house such as a building or an apartment.
[0002]
[Prior art]
Conventionally, automatic fire alarm systems have been introduced in apartment buildings such as buildings and condominiums.Disaster prevention receivers have been installed in managers' offices and disaster prevention centers, etc. The system is configured by connecting a plurality of detector lines connected to the fire detectors.
[0003]
When the fire prevention receiver receives an alarm signal (operation signal) of the fire detector from any of the detector lines, it turns on or flashes the fire indicator light and outputs a fire alarm by alarm sound or voice message. I have.
In general, this type of disaster prevention receiver has a storage function to prevent false alarms at the disaster prevention receiver due to false alarms from the fire detector, and an alarm is output when the fire detector activation signal is first received. Is not performed, and an alarm is output only when an operation signal is continuously received for a preset accumulation time.
[0004]
In addition, a sprinkler line that detects the operation of sprinklers that spray water to extinguish a fire is connected to the disaster prevention receiver. The indicator lamp is turned on or blinks, and a fire alarm is output by an alarm sound or a voice message.
[0005]
[Problems to be solved by the invention]
However, in the conventional automatic fire alarm system, as described above, the disaster prevention receiver performs the same operation when the fire detector emits an alarm and when the sprinkler operates, and the fire detector and the sprinkler monitor line are connected to each other. Without distinguishing between the two lines, the operation of the installed disaster prevention terminal had to be checked at the site.
[0006]
Therefore, when the storage function is set, even if the sprinkler operates, if the predetermined storage time does not elapse, it is not determined that the fire has occurred, and the fire response may be delayed.
In addition, the disaster prevention receiver enables the setting and release of the storage function by a switch operation, etc., but this operation is effective for all monitoring lines connected to the disaster prevention receiver. Therefore, if the storage function is set, quick alarm output at the time of sprinkler operation cannot be performed.On the other hand, if the storage function is released, false alarm at the time of fire alarm firing cannot be effectively prevented. Was.
[0007]
The present invention has been made in view of the above circumstances, and divides each of the monitoring lines into a sensor line and a sprinkler line, and sets and releases an accumulation operation for each monitoring line. It aims to provide a fire alarm system.
[0008]
[Means for Solving the Problems]
In order to achieve the above object, in the automatic fire alarm system according to claim 1 of the present invention , a line for setting line type and storage operation setting / cancellation for each monitoring line derived from the disaster prevention receiver. Type setting means is provided, and when the line type is set for each monitoring line by the line type setting means, the storage operation is set or canceled for the monitoring line in cooperation therewith. .
Here, the accumulation operation means that even if an operation signal of the disaster prevention terminal connected to the line is received through the monitoring line, if the operation signal is not continuously received for a preset accumulation time, the disaster prevention terminal is not received. This is a function that does not determine that has been activated and does not output an alarm.
[0009]
According to a second aspect, in the first aspect, the line type setting means sets a monitoring line for setting the storage operation to a sensor line and a monitoring line for canceling the storage operation to a sprinkler line. That is, here, in addition to the storage line and the non-storage line, the line type can be set to a sensor line or a sprinkler line corresponding to these. The fire alarm connected to the sensor line may be a false alarm due to cigarette smoke or hot air. Therefore, the accumulation operation is set for the disaster prevention receiver. On the other hand, even if the sprinkler is operated erroneously, it is necessary to take immediate action, so that the accumulation operation is canceled.
[0010]
In claim 3, the line type setting means according to claim 1, wherein, among the monitoring lines derived from the disaster prevention receiver to the common part of the apartment house, the monitoring line for setting the storage operation is the sensor line, and the storage operation is released. The monitoring line to be used is a sprinkler line.
Here, a line type is set for a monitoring line led to a common area such as a corridor, stairs, or an elevator hall. If a fire alarm monitor is used to monitor the fire at each dwelling unit in a dwelling unit via a multiplex transmission line, the type of surveillance line derived into each dwelling unit will be the housing information panel. Since it can be identified by the multiplexed signal transmitted from, the monitoring line of only the common unit is set as the line type setting target.
[0011]
According to a fourth aspect, in the third aspect, the line type setting means further includes, among the monitoring lines derived from the disaster prevention receiver to each dwelling unit of the apartment house, a monitoring line for setting an accumulation operation, a sensor line, and a storage operation. The monitoring line for canceling is called a sprinkler line.
Here, the monitoring line derived to each dwelling unit is also set as the line type. Thus, the disaster prevention receiver can also determine, as the type of the monitoring line, the place where the line is derived.
[0012]
According to a fifth aspect, in any one of the first to fourth aspects, the disaster prevention receiver further includes an operation unit and a storage unit that stores a line type corresponding to each monitoring line. Is configured to store the line type selected for each of the monitoring lines in the storage unit after the operation unit sets the line type setting mode. That is, here, the line type setting means is configured in a manner like a memory switch.
[0013]
According to a sixth aspect of the present invention, in any one of the first to fourth aspects, the line type setting means comprises switch means capable of selectively setting the line type of each monitoring line. As this switch means, a dip switch is preferably used.
According to claim 7, in any one of claims 1 to 6, the disaster prevention receiver, when receiving the operation signal of the disaster prevention terminal via the monitoring line, determines the monitoring line determined based on the line type setting means. Display means for displaying is further provided. Here, the display means includes a 7-segment display, a liquid crystal screen, an LED lamp, and the like, and displays, in addition to the determined monitoring line, information set in advance corresponding thereto.

BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a block diagram showing a configuration of a main part of the automatic fire alarm system of the present invention.
In apartment buildings such as buildings and condominiums, the disaster prevention receiver 1 is installed in the manager's office, disaster prevention center, etc. This disaster prevention receiver 1 leads out a monitoring line to the appropriate place in the apartment house, Monitoring.
[0016]
Here, the disaster prevention receiver 1 derives, as monitoring lines, detector lines L11 and L12 connecting fire detectors S1 and S2, and sprinkler lines L21 and L22 connecting sprinklers SP1 and SP2. The figure shows a case where the line is a so-called P-type receiver that is independent of the disaster prevention receiver 1 and is wired as a Zoro wire.
If the disaster prevention receiver 1 receives any one of the operation signals of the fire detectors S1 and S2 and the sprinklers SP1 and SP2, which are disaster prevention terminals, through the respective lines L11, L12, L21 and L22, the display to the display unit 14 is made. An alarm is output by display or a sound from the sound output unit 15 to prompt a manager or the like to take prompt action.
[0017]
In the figure, reference numeral 10 denotes a signal processing unit for controlling the whole of the disaster prevention receiver 1, reference numeral 11 denotes a signal detection unit for detecting a signal transmitted from each line, and reference numeral 12 denotes a line type of each monitoring line. A line type setting unit 13 as a means for setting is constituted by various switches and keys, etc., and an operation unit as a means for operating to perform operation instructions and various settings for the disaster prevention receiver 1, and 14 is a 7-segment display and A display unit comprising a liquid crystal screen, an LED lamp, and the like, which is a means for displaying the operation status of the disaster prevention receiver 1 and the like, 15 is provided with a speaker SP, and is an audio output which is a means for outputting sound such as a voice message or an alarm sound Department.
[0018]
In the present invention, the accumulation operation can be set and canceled for each of the monitoring lines derived from the disaster prevention receiver 1 by the line type setting unit 12, and the signal processing unit 10 When an operation signal from the disaster prevention terminal connected to the line is detected through the monitoring line for which the accumulation operation has been set, an alarm is not output immediately, but for a preset accumulation time (for example, 10 seconds). Only when the operation signal is continuously received, it is determined that the disaster prevention terminal has been activated due to an actual fire or the like, and an alarm is output. On the other hand, when an operation signal from a disaster prevention terminal connected to the monitoring line is detected through the monitoring line whose storage operation has been canceled, an alarm is output immediately.
[0019]
If the storage operation can be set and canceled for each monitoring line in this way, the disaster prevention receiver 1 can monitor the characteristics of the disaster prevention terminal connected to each monitoring line and the purpose of use.
Therefore, in the line type setting unit 12, the monitoring lines for setting the accumulation operation may be sensor lines L11 and L12, and the monitoring lines L21 and L22 for canceling the accumulation operation may be sprinkler lines. The fire alarms of the fire detectors S1 and S2 connected to the detector lines L11 and L12 may be false alarms due to cigarette smoke or hot air. Therefore, if the accumulation operation is set, the reliability of the system is maintained. be able to. On the other hand, since the sprinklers SP1 and SP2 have already started sprinkling, it is necessary to immediately take measures even if they are erroneously operated, and the accumulation operation is canceled.
[0020]
In the line type setting unit 12, among the monitoring lines led to the common use unit of the apartment house, the monitoring line for setting the storage operation is the sensor line L11, and the monitoring line for canceling the storage operation is the sprinkler line L21. Of the monitoring lines led to the dwelling unit, if the monitoring line for setting the storage operation is the sensor line L12 and the monitoring line for canceling the storage operation is the sprinkler line L22, the disaster prevention receiver 1 has the following types of monitoring lines. The location from which the line is derived can also be determined, and a corresponding alarm can be output.
[0021]
FIG. 2 shows an example of the setting contents of the line type setting unit 12. Here, the line type is set and registered in association with the line number assigned to each of the monitoring lines in advance. In (a), lines for distinguishing the sensor lines L11 and L12 from the sprinkler lines L21 and L22. In addition to the type, the setting or cancellation of the storage operation is shown in (b), where the installation location of the line (and the disaster prevention receiver) is further registered. Here, the installation location is not a separate one such as a common use unit and a dwelling unit, but a more specific location is registered so that a manager or the like can easily understand and cope with the alarm output.
[0022]
Next, the configuration of the line type setting unit 12 will be described.
The line type setting unit 12 is configured as a storage unit (memory). After the line type setting mode is set by the operation of the operation unit 13 and a line type is selected for each of the monitoring lines, the selected line type is stored in the line type setting unit 12. In FIG. 3, an example of the operation procedure at this time is described by a change (transition) of the display of the seven-segment display of the display unit 14.
[0023]
First, when the mode switch 13a is operated, "0000" indicating that the apparatus is in the input waiting state is displayed on the 7-segment display ((1)). In this state, the ten key 13b is operated to input a line number (here, line number "18") to be set and registered in the line type setting unit 12 ((2)), and an input complete key (not shown) is operated. Then, the state returns to the input standby state (3). Subsequently, the line type (here, the detector line "1") is input by operating the numeric keypad 13b ((4)), and the mode switch 13a is operated to release the line type setting mode ((4)). 5 ▼).
[0024]
Note that the procedure here is merely an example, and the present invention is not limited to this. Further, if the display unit 14 is configured by a liquid crystal screen, a CRT, or the like, and the operation unit 13 is configured by a keyboard or the like, settings can be registered in the line type setting unit 12 by inputting characters and symbols.
Further, the line type setting unit 12 can be configured by a switch unit that can select and set the line type of each monitoring line. FIG. 4 shows a case where the switch means is constituted by a dip switch, and for each line number, a distinction is made between a detector line and a sprinkler line. Here, the storage operation can be automatically set or canceled in cooperation with the line type.
[0025]
Next, an alarm output in the disaster prevention receiver 1 will be described.
When receiving the operation signal of the disaster prevention terminal via the monitoring line, the disaster prevention receiver 1 displays information on the monitoring line determined based on the line type setting unit 12 on the display unit 14. In addition, information of the determined monitoring line is output from the speaker SP by the sound output unit 15.
[0026]
FIGS. 5A and 5B show examples of display by the display unit 14, wherein FIG. 5A shows a case where the line receiving the signal is a monitoring line of a dwelling unit, and FIG. I have. Here, the display of the dwelling unit is a dwelling unit number ("101" in the figure), and the display of the common unit is a line number to which an identification code ("A-" in the figure) is added. When it is determined that the line type is the sprinkler line L21, L22, the sprinkler representative light 14a is further turned on or blinks to distinguish it from the sensor lines L11, L12.
[0027]
Also, the sound output is made by a sound message such as “The sprinkler of the common unit 60 line has been activated” from the sound output unit 15 by determining the line type and line number.
Next, another configuration of the main part of the automatic fire alarm system will be described with reference to FIG. Here, the disaster prevention receiver 1 derives the detector line L11 and the sprinkler line L21 as a monitoring line to the common unit, and derives the multiplex transmission line L to connect the house information panel 2 of each dwelling unit. are doing. This is a system using a so-called P-type and R-type receiver.
[0028]
The house information panel 2 of each dwelling unit derives a detector line L13 to which the fire detector S3 is connected and a sprinkler line L23 to which the sprinkler S3 is connected. If an operation signal is received through these lines L13 and L23, An operation signal with its own address added and a line type set is transmitted via the multiplex transmission line L.
The signal processing unit 10 of the disaster prevention receiver 1 normally monitors the state of each house information panel 2 by controlling the polling operation by the multiplex transmission unit 16, but when the above operation signal is interrupted and received, When the signal is analyzed and the content indicates the operation on the sensor line L13, after performing the accumulation operation, an alarm output is performed by the display unit 14 and the sound output unit 15, while the sprinkler line L23 is used. When the operation is indicated, the alarm is output without performing the accumulation operation. In this case, the line type setting unit 12 may select and register the line type only for the monitoring line of the common unit without setting the monitoring line of each dwelling unit as the target of setting registration.
[0029]
【The invention's effect】
As can be understood from the above description, the present invention has the following effects. That is, according to the automatic fire alarm system according to the first aspect, the accumulation operation can be set and canceled for each of the monitoring lines derived from the disaster prevention receiver.

According to the second aspect, since the monitoring line for setting the storage operation is a sensor line and the monitoring line for canceling the storage operation is a sprinkler line, false alarm can be effectively prevented when the fire detector is activated. When the sprinkler is activated, it is possible to take an action immediately.
According to the third aspect of the present invention, only the monitoring line for setting the storage operation is the sensor line and the monitoring line for canceling the storage operation is the sprinkler line only for the monitoring line led to the common part of the apartment house. Even when the housing information panels of each dwelling unit are connected via a multiplex transmission line, it is possible to cope with the operation of the disaster prevention receiver on the monitoring line of the common unit with the same effect as in claim 2. I can do it.
[0031]
According to the fourth aspect, with respect to the monitoring line led to each dwelling unit of the apartment house, the monitoring line for setting the storage operation is a sensor line, and the monitoring line for canceling the storage operation is a sprinkler line. As the type of the monitoring line, the place where the line is derived can also be determined.
According to the fifth aspect, the line type for each monitoring line can be easily registered and set by the switch for each line in the sixth aspect, so that the work efficiency at the site, such as during construction, can be particularly improved. .
