Description

  The present invention relates to an improvement of an automatic fire alarm facility for monitoring a fire at a facility to be warned.

  When a receiver, detector, district bell, smoke prevention equipment, fire extinguishing equipment, etc. are installed in a facility subject to warning, such as a building, and connected by a line to configure an automatic fire alarm equipment, with only one receiver, There are times when the input / output terminals of the line are insufficient or the power capacity is insufficient. Conventionally, such a case has been dealt with by connecting a plurality of receivers to each other. However, in the mutual ring connection, it is necessary to cross-connect the fire representative output terminal and the input terminal between the receivers, so that there is a problem that the cross-connected input terminal cannot be used for connection of the sensor. In addition, when mutual ringing connections are made, it becomes difficult to link the upper floor of the fire directly at the part straddling the receiver.

  The following patent document 1 can be given as an example of the prior art that addresses such a problem. This document describes that information can be shared among a plurality of receivers connected by a LAN, and the interlocked device is linked to the fire detector notification between different receivers. ing. Specifically, the receiver that the fire detector has reported activates the controlled device in the zone in the receiver, and at the same time, flows the information of the shared zone on the LAN, and other receivers use the common zone from the information. Is recognized, and the controlled device in the common zone is activated.

  By the way, in the fire alarm system described in Patent Document 1, all receivers have the same configuration, and each of them requires a zone setting. That is, since each receiver must have a function of interlock control, the entire system is expensive, and the work for setting the zone for each receiver is complicated, so that setting errors and the like are likely to occur. It is believed that there is.

  Therefore, the present invention can easily solve the shortage of input terminals and power supply capacity while suppressing cost when there is a shortage of input / output terminals or power supply capacity with only one receiver. The purpose is to.

  The present invention is a receiver expansion device for expanding the number of lines that can be monitored and controlled by a fire receiver, and has an input terminal and an output terminal, and monitors a line connected to the input terminal, A line monitoring control unit that drives a line connected to the output terminal and a communication terminal connected to the parent receiver, and transmits a monitoring state for each line to the parent receiver, while receiving a line from the parent receiver And an interlocking communication unit that causes the line monitoring control unit to execute each drive command.

  The receiver extension device may further include a power supply unit that receives a commercial power supply and supplies power to the line monitoring control unit.

  The present invention is also a fire receiver to which the receiver expansion device is connected. The fire receiver has an input terminal and an output terminal. The fire alarm is monitored on a line connected to the input terminal, and the output terminal A line monitoring control unit for driving a connected line; and a communication terminal for connecting to the receiver expansion device, and receiving a monitoring state for each line from the receiver expansion device, while the line is connected to the receiver expansion device.

  Further, the present invention provides an automatic fire alarm facility in which the receiver expansion device is connected to the fire receiver, and the expansion facility and the fire receiver share the entire facility to be monitored. It is characterized by doing.

  In the present invention, when the input / output terminal of the receiver is insufficient or when the power capacity is insufficient, the shortage can be solved by simply connecting a receiver expansion device to the receiver. Also, the receiver extension device can be provided at a low cost because it has a simpler configuration than the receiver. Since the link relationship between the overall line notification and driving may be set by the receiver, the setting operation is simple and errors are unlikely to occur.

  The present invention assumes a fire receiver that monitors the fire of the facility to be warned and controls the district bell, smoke prevention equipment, fire extinguishing equipment, etc. according to the fire alarm, and can monitor and control the receiver. The purpose is to extend the number of lines by a receiver expansion device. Although a P-type receiver is suitable as a receiver, the present invention can be similarly applied to an R-type receiver.

  In the following description, for the sake of simplicity, an embodiment in which a district bell is assumed to be linked to a fire alarm will be described. However, smoke-exhaust equipment, fire-extinguishing equipment, and the like can be linked by a similar mechanism.

  The expansion device 10 includes the following line monitoring control unit 10a and linked communication unit 10b as elements according to the present invention.

  The line monitoring control unit 10a is a functional block that has a plurality of input terminals T1 and output terminals T2, and monitors the line connected to the input terminal T1, while driving the line connected to the output terminal T2. . A display line L to which various sensors 2 are connected is connected to the input terminal T1, and a bell line BL to which the district bell 3 is connected is connected to the output terminal T2. Although a common terminal is provided for the input terminal T1 and the output terminal T2, it is omitted in the figure.

  The line monitoring control unit 10a supplies power to the sensor 2 from the input terminal T1 via the display line L. When the sensor 2 detects a fire, it issues a notification by short-circuiting the display line L. The line monitoring control unit 10a determines the fire for each display line L after accumulating the notifications of the display lines L for a predetermined time in order to prevent false reports. The accumulation time is preset with a dip switch or the like (not shown). The sensor 2 that has issued the alarm is reset by stopping the power supply to the display line L for a predetermined time after the fire extinguishing operation and turning it on again, thereby recovering it. The number of sensors 2 connected to the display line L is limited by the power supply capacity.

  Further, the line monitoring control unit 10a supplies power to the district bell 3 from the output terminal T2 via the bell line BL at the time of district ringing, and the district bell 3 rings while the power is supplied. ing. The number of district bells 3 connected to the bell line BL is limited by the power supply capacity.

  The interlocking communication unit 10b has a communication terminal T3 connected to the parent receiver, and transmits the monitoring state for each line to the parent receiver. On the other hand, the line monitoring control unit 10a receives a drive command for each line received from the parent receiver. Is a functional block to be executed. That is, the line monitoring controller 10a notifies the parent receiver of the notification for each display line L connected to the input terminal T1, and follows the display line L restoration command, the bell line BL drive command, etc. received from the parent receiver. The alarmed sensor 2 is restored or the district bell 3 is sounded.

  The expansion device 10 may receive power from the parent receiver, but may further include a power supply unit 10c that receives commercial power and supplies power to the line monitoring control unit 10a. If an independent power supply unit 10c is provided in the expansion device 10, it is possible to connect as many detectors 2 and district bells 3 as necessary to the expansion device 10 without being limited by the power supply capacity of the parent receiver.

  Thus, since the expansion apparatus 10 is a simple structure, the whole cost of the automatic fire alarm equipment 1 using this can be suppressed.

  On the other hand, the receiver 20 includes the following line monitoring control unit 20a, linked communication unit 20b, extended display control unit 20d, and extended linked setting unit 20e as elements according to the present invention.

  The line monitoring control unit 20a has a plurality of input terminals T1 and output terminals T2, and monitors the alerting of the line connected to the input terminal T1, while driving the line connected to the output terminal T2. It is a block. This functional block basically has the same configuration as that of the expansion device 10, but the number of input terminals T1 and the number of output terminals T2 may be different from those of the expansion device 10.

  The interlocking communication unit 20b has the communication terminal T3 connected to the expansion device 10 with the receiver 20 as a parent receiver, and receives the line monitoring state from the expansion device 10, while issuing a line drive command to the expansion device 10. This is a functional block to be transmitted.

  The extended display control unit 20d is a functional block that has a display window 20g and displays the districts by integrating the notifications of the lines connected to the own device and the extended device 10. That is, in the display window 20g of the receiver 20, the district display is performed as if the combination of the receiver 20 and the expansion device 10 is a single receiver. A specific display example will be described later. The number of districts to be displayed here varies depending on the number of expansion devices 10 connected to the receiver 20, and the display window 20g may be configured with a liquid crystal panel or the like so that flexible display is possible.

  The expansion interlocking setting unit 20e has an operation unit 20f, and an overall interlocking relationship between the notification of the line connected to the own device and the expansion device 10 and the driving of the line connected to the own device and the expansion device 10 It is a functional block that accepts the setting. The operation unit 20f is provided with various operation keys such as a district bell stop, a release key, a recovery key, an interlocking setting key, and a test key. When setting the interlocking relationship, it is preferable that interactive operation can be performed in cooperation with the display window 20g of the extended display control unit 20d. A specific example of setting the interlocking relationship will be described later.

  The receiver 20 includes a power supply unit 20c that receives commercial power and supplies power to the line monitoring control unit 20a.

  The method of signal transmission between the expansion device 10 and the receiver 20 is not particularly limited. The receiver 20 may receive a monitoring state for each line from each of the expansion devices 10 by polling and selecting methods, and may transmit a drive command for each line to each of the expansion devices 10. Alternatively, the TCP / IP method may be adopted as a signal transmission method, and the expansion device 10 and the receiver 20 may spontaneously transmit a monitoring state and a drive command, respectively.

  The monitoring state signal transmitted by the expansion device 10 includes identification information (address) of the expansion device 10, identification information (address) of the display line L, and state information. On the other hand, the drive command transmitted by the receiver 20 includes identification information (address) of the expansion device 10, identification information (address) of the bell line BL, and command content. In the case of the polling and selecting method, the receiver 20 designates the extension device 10 of the communication partner and performs communication control. Therefore, the identification information of the extension device 10 is included in the designation.

  As shown in FIG. 2, in the automatic fire alarm facility 1, a plurality of expansion devices 10 are connected to the receiver 20 via the communication line CL and the hub 4. Each of the expansion devices 10 and the receiver 20 are connected to a plurality of sensors 2 and a district bell 3 by display lines L and bell lines BL. The number of expansion devices 10 connected to the receiver 20 is not particularly limited.

  Identification information is set in each of the expansion device 10 and the receiver 20 before the operation of the automatic fire alarm facility 1 starts.

  As described above, according to the present invention, when the input / output terminals T1 and T2 of the receiver 20 are insufficient or when the power supply capacity is insufficient, the shortage can be solved only by connecting the expansion device 10 to the receiver 20. .

  If the monitored facility is a building on the second basement floor and the eighth floor, for example, the receiver 20 monitors the second floor to the second floor, and the first expansion device 10 monitors the third floor to the sixth floor, As the second expansion device 10 (not shown) monitors the seventh floor and the eighth floor, the expansion device 10 and the receiver 20 may share and monitor the entire facility to be warned. .

  The receiver 20 is provided with a display lamp 20h for notifying a power supply state, a warning state, and the occurrence of a trouble at the upper front part of the housing, and below that, a display window 20g composed of a liquid crystal panel, a fire lamp, An emergency lamp 20i such as an alarm lamp is provided. Further below that, main operation keys 20j such as a receiver sound stop key, a district bell stop key, a release key, and a recovery key are provided. Further below that, a sub operation key 20k is provided for setting an interlocking relationship and performing a test. The sub operation key 20k is hidden by the protective panel 20m so as not to be erroneously operated.

  The operation of the automatic fire alarm system 1 is basically the same as the conventional one. That is, the receiver 20 performs district display and interlocking control as if the combination of the receiver and the expansion device 10 is a single receiver.

  An example of a specific basic operation of the automatic fire alarm facility 1 will be briefly described. In the alert state, the receiver 20 of each of the expansion devices 10 monitors the display line L derived from the own device.

  During the monitoring, when the expansion device 10 senses a notification on any of the display lines L, the expansion device 10 starts the accumulation operation and transmits the accumulation operation to the receiver 20. Receiving this, the receiver 20 changes the part corresponding to the display line L in the area display by the display window 20g during accumulation.

  When the accumulating time of the alarm elapses, the expansion device 10 transmits a fire occurrence (first report) to the receiver 20. Receiving this, the receiver 20 turns on the fire lamp and changes the corresponding part of the district display during the occurrence of the fire. Further, the receiver 20 starts outputting the receiver sound such as “Peeper, sensor has been activated. Please check the site”, and the bell line BL set in conjunction with the display line L is started. A drive command is transmitted to the expansion device 10. Receiving this, the expansion device 10 drives the bell line BL specified by the drive command to ring the district bell 3. Here, if an interlocking relationship is also set for the bell line BL of the receiver 20, the receiver 20 drives the bell line BL to ring the district bell 3.

  The disaster prevention staff operates the receiver acoustic stop key, the district bell stop key, etc. with the receiver 20 to confirm the site. The receiver 20 stops the receiver sound and transmits a stop command for the bell line BL to the expansion device 10. As a result, the ringing of the district bell 3 connected to the bell line BL of the expansion device 10 is also stopped. The disaster prevention staff operates the recovery key of the receiver 20 if the misinformation is confirmed. In response to this, the receiver 20 restores the fire lamp and the district display, and transmits a restoration command to the expansion device 10 to restore the sensor 2 of the notified display line L.

  When the recovery key is not operated before the predetermined time elapses from the start of ringing of the district bell 3, when the receiver 20 determines that the display line L is in fire or when the expansion device 10 is in fire (No. 2), the receiver 20 changes the corresponding part of the district display during a fire. Furthermore, the receiver 20 starts outputting the receiver sound such as “Peep, fire, fire. Please check the site” and resumes the ringing of the district bell 3 that has been stopped (sequential ringing). ). At this time, the drive command for the bell line BL is retransmitted to the expansion device 10. The disaster prevention staff performs a fire check, 119 report, evacuation guidance, etc., and then checks the fire extinguishing, and then operates the recovery key of the receiver 20. As a result, the receiver 20 restores the fire lamp and the district display, and transmits a restoration command to the expansion device 10 to restore the sensor 2 of the notified display line L.

  On the other hand, when the receiver 20 senses an alert on any of the display lines L in the alert state, the receiver 20 starts the accumulation operation and changes the corresponding part of the district display during accumulation.

  When the accumulated time of the notification has elapsed, the receiver 20 turns on the fire lamp and changes the corresponding part of the district display during the occurrence of the fire. Further, the receiver 20 starts outputting the receiver sound such as “Peep, the sensor has been activated. Please check the site”, and the interlocking relationship is set for the display line L. The driving of the bell line BL is started to ring the district bell 3. If an interlocking relationship is also set for the bell line BL of the expansion device 10, the receiver 20 transmits to the expansion device 10 a drive command for the bell line BL that is interlocked with the display line L. , Ring the district bell 3.

  When the disaster prevention staff operates the receiver acoustic stop key, the district bell stop key, etc. with the receiver 20, the receiver acoustics and the district bell 3 are temporarily stopped. At this time, if necessary, a stop command for the bell line BL is transmitted to the expansion device 10. If the disaster prevention staff confirms the misinformation and operates the recovery key of the receiver 20, the receiver 20 restores the fire lamp and the district display, and also restores the sensor 2 of the indicated display line L.

  When the recovery key is not operated before the predetermined time has elapsed from the start of ringing of the district bell 3, when the receiver 20 determines that the fire of the display line L has occurred, or the expansion device 10 When notified, the receiver 20 changes the corresponding part of the district display during a fire. Furthermore, the receiver 20 starts outputting the receiver sound such as “Peep, fire, fire. Please check the site” and resumes the ringing of the district bell 3 that has been stopped (sequential ringing). ). At this time, if necessary, the drive command for the bell line BL is retransmitted to the expansion device 10. Thereafter, when the disaster prevention staff operates the recovery key, the receiver 20 restores the fire lamp and the district display, and also restores the sensor 2 of the displayed display line L.

  FIG. 3 is a matrix showing a specific example of setting of the interlocking relationship in the extended interlocking setting unit of the receiver. Here, it is assumed that the monitoring target facility is a building on the second basement floor and the eighth floor above the ground, and is shared by the receiver and the two expansion devices.

  The receiver monitors the second to second floors, the first expansion device monitors the third to sixth floors, and the second expansion device monitors the seventh and eighth floors.

  The matrix G1 in the figure receives the display line notification in the receiver, the first expansion device, and the second expansion device as an input, and the receiver, the first expansion device, and the bell in the second expansion device. The line drive is set as an output, and an interlocking relationship is set at the intersection of each row indicating the input and each column indicating the output. Note that, in the matrix G1, a solid line frame indicates an interlocking relationship setting area in the receiver, and a broken line frame indicates an interlocking relationship setting area expanded by two expansion devices.

  The presence or absence of the interlocking relationship is indicated by a circle in the figure. In this example, the ringing of the fire floor and the floor directly above is set. That is, if the fire floor is a basement, the fire floor, the directly above floor, and other basements are ringed. If the fire floor is the first floor, the fire floor, the directly above floor, and the basement are ringed, and the fire floor is the second floor or higher. The whole interlocking relationship is set so that the fire floor and the directly above floor ring.

  The specific setting operation of the interlocking relationship is not particularly limited. For example, such a matrix G1 is displayed on the display window, a desired intersection of the matrix G1 is selected, and the interlocking relationship of the selected intersection can be set or canceled. It may be. At this time, the extension interlock setting unit of the receiver may determine the number of extension devices connected to the receiver and automatically generate a matrix G1 corresponding to the number. In this way, if the linkage relationship can be set uniformly in one place, that is, one receiver, for the entire monitored facility, it is easy to set even in the case of a linkage relationship that spans the receiver and the expansion device. It is possible to make setting mistakes.

  FIG. 4 is a table showing a specific example of district display by the extended display control unit of the receiver. Similar to FIG. 3, this district display assumes a case in which a building on the second basement floor and the eighth floor is shared and monitored by the receiver and the two expansion devices.

  The table G2 in the figure is a list display in which the monitor state of the display lines in the receiver, the first expansion device, and the second expansion device is displayed as each row. Specifically, in order from the bottom of the table G2, the monitoring states of the display lines 1 to 4 of the receiver, the display lines 1 to 4 of the first expansion device, and the display lines 1 to 4 of the second expansion device are displayed. The district is displayed in a single table G2. In the table G2, during the accumulation of display lines, the occurrence of fire is indicated by a circle. At this time, the extended display control unit of the receiver may determine the number of expansion devices connected to the receiver and automatically generate a table G2 corresponding to the number. With such a display mode, the monitoring status of the display line of the receiver and the display line of the expansion device can be understood at a glance compared to the mode of displaying the monitoring status of the display line of the receiver and the expansion device at a glance. Such mistakes can be prevented.

  In this example, if the receiver display line 4 (2nd floor) is in fire, and the interlocking relationship is set as shown in FIG. 3, the receiver's bell line 4 (2nd floor) The bell line 1 (third floor) of the first expansion device is driven, and the district bell connected to these bell lines 4 and 1 is ringed.
