Description

[0001]
[Industrial applications]
The present invention relates to a fire receiver, and more particularly to a fire receiver used in a fire alarm system in which a plurality of fire receivers are connected and one is used as a main panel and the other is used as a sub panel.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, a P-type receiver (hereinafter, referred to as a sub-receiver) as a sub-panel for each floor has been disposed as a fire alarm system, and a P-type receiver (hereinafter, referred to as a main panel) which receives a transfer output from these sub-panels. , A main receiver) is installed to monitor the entire building. When a sub-receiver receives a fire signal from any of the fire detectors through a plurality of detector lines provided for each fire area, the sub-receiver outputs the fire signal reception as a so-called representative transfer. The main receiver that has received the representative transfer receives the representative transfer, performs necessary display and alarm, and performs fire monitoring for the entire building.
[0003]
In constructing such a system, a general fire receiver's transfer output function is used (see, for example, Patent Document 1), and a fire detector for a small building with a small number of lines that can be monitored is used. However, by integrating the information output from a plurality of fire receivers, the invention can be applied to a large-scale building.

[0005]
[Problems to be solved by the invention]
When using the fire output function of the fire receiver as described above, once the fire output signal is output according to the principle of fire alarm equipment, after confirming the site to erase the fire signal once raised, The output is maintained, and the output is held until the fire is eliminated and a recovery operation input is performed.
[0006]
Similarly, the main receiver receiving the broadcast output once holds the fire information once received from the sub receiver, and thereafter holds the fire information until a recovery operation input is made regardless of the actual reception. With such a system configuration, if multiple fire alarms occur, a sub-receiver may output a fire representative signal and the main receiver receives the signal output and sounds a fire alarm. When the sound stop input is made to the main receiver, and the sub-recipient that has performed the fire representative transfer output has the fire signal of the second report thereafter, the fire representative for the main receiver is returned again. Cannot be output, and the main receiver cannot perform sounding based on the fire signal of the second report.
[0007]
That is, in the sub receiver, there is an acoustic sound due to the reception of the first report fire signal, and after the sound is stopped, it is possible to perform the acoustic sound due to the reception of the second report fire signal from a different line, so-called subsequent re-sound. However, the main receiver cannot receive the subsequent signal from the same sub receiver as the first report, and cannot perform the subsequent re-ringing.
[0008]
Accordingly, an object of the present invention is to receive a fire representative transfer output and the like for each fire alarm.
[0009]

[0020]
Each of the sub receivers R1 to Rn is arranged on each floor as an example with respect to the building, and output lines 21 to 2n for outputting the fire representatives are drawn out, input to the main receiver Rm, and output to the main receiver Rm. Stop lines 31 to 3n are arranged between the main receiver Rm.

Each of the sensor lines 41 to 4n is also provided with a necessary number of lines corresponding to the district division set for fire monitoring.
[0022]
Similarly, each of the sub receivers R1 to Rn includes a plurality of local acoustic control lines 51 to 5n, and a necessary local acoustic device 13 is provided in the floor. Then, an alarm can be sounded on the entire floor. In addition, it is also possible to divide the area inside the floor similarly to the fire monitoring and individually control the sound.
[0023]
Further, since the main receiver Rm is a P-type fire receiver similar to the sub receivers R1 to Rn as described above, similarly, the necessary detector line 4m is provided and the fire detector 11 and the fire transmitter 12 can be connected, and the control line 5m can be provided to connect the district acoustic device 13.
[0024]
Next, the configuration of the main receiver Rm and the sub receivers R1 to Rn will be described. In the present embodiment, the main receiver Rm and the sub receivers R1 to Rn are each provided with one P-type fire receiver housing. We share. For this reason, there are parts used only in the main receiver Rm and parts used only in the sub receivers R1 to Rn, but there is no need to prepare them separately, and only one product is manufactured. FIG. 2 shows wiring and peripheral devices when used as a sub receiver.
[0025]
2, reference numeral 61 denotes a control unit, 62 denotes a fire receiving circuit, 63 denotes an operation unit, 64 denotes a display unit, 65 denotes a sound unit, 66 denotes a control output unit, 67 denotes a notification output circuit, 68 denotes a reset output circuit, and 69 denotes a reset output circuit. Is a reset receiving circuit.
[0026]
The control unit 61 is configured by a microcomputer, a memory, and the like (not shown) and controls the entire operation of the fire receivers R1 to Rn and Rm. The control unit 61 detects an input to the fire reception circuit 62 and the like, and sends a signal to the control output unit 66 and the like. Performs control output and performs necessary monitoring and control operations.
[0027]
The fire receiving circuit 62 is a circuit that detects the reception of a fire signal based on the state between terminals to which the sensor lines 41 to 4n and the like are connected, and performs a P-type fire signal transmission operation when the fire detector 11 detects a fire. It is possible to detect the occurrence of a short-circuited, low impedance state due to a so-called switching operation, and to detect a fire signal for each of a plurality of provided lines. Although not described in detail, a disconnection detection circuit for detecting the occurrence of disconnection of each of the sensor lines 41 to 4n is provided in the fire receiving circuit 62.
[0028]
When used as the main receiver Rm, the fire receiving circuit 62 is connected to fire representative output lines 21 to 2n in addition to the detector line 4m. The representative transfer is also received.
[0029]
The operation unit 63 is configured to perform an operation input to the fire receivers R1 to Rn and Rm by various switches provided on the panel as illustrated in FIG. 3 and output the input to the control unit 61. FIG. 2 shows only the sound stop switch SW1 and the recovery switch SW2.
[0030]
The display unit 64 is connected with various display lamps indicating the status and an alarm display (7-segment) indicating the line of the fire alarm, as well as the area window display as shown in FIG. The lighting is controlled.
[0031]
Although not described in detail, the sound unit 65 is a device such as a buzzer, and emits an alarm sound from the fire receivers R1 to Rn and Rm themselves.
[0032]
The control output unit 66 outputs a control output to a terminal to which the control line 51 to 5n of the district sound is connected, and controls the alarm sound of the district sound device 13. Even if a controlled device other than the district sound device 13 such as a smoke prevention device or an evacuation guidance device is connected, the interlocking control can be performed similarly to the district sound.
[0033]
The output notification circuit 67 performs a notification output operation to a terminal to which the fire representative output lines 21 to 2n are connected based on the control output of the control unit 61. Therefore, in order to make the connection state similar to the sensor lines 41 to 4n, conduction of the monitoring current is enabled via a resistor 82 similar to a terminating resistor (not shown) provided at the terminal portion of the sensor lines 41 to 4n, When the switching element 81 is actuated, an additional resistor 83 for providing the same addition as that of the fire detector 11 is provided, and similarly to the fire signal, the transfer output lines 21 to 2n are set to a substantially short-circuited low impedance state. .
[0034]
The reset output circuit 68 controls on / off of a photocoupler 85 as a switching element that controls between terminals to which the acoustic control lines 31 to 3n are connected, based on a control output of the control unit 61. This reset output circuit 68 is a necessary part when used as the sub receivers R1 to Rn, and is not necessary as the main receiver Rm.
[0035]
The reset input circuit 69 detects that the photocoupler 85 is turned on by the reset output circuit 68, and inputs the detection to the control unit 61. The reset input circuit 69 is necessary only when used as the main receiver Rm, and is unnecessary when used as the sub receivers R1 to Rn, contrary to the reset output circuit.
[0036]
Next, the operation of the embodiment configured as described above will be described with reference to FIG. The following description of the operation will be made while distinguishing between the main receiver Rm and the sub receivers R1 to Rn. However, since a fire receiver having a common configuration can be prepared, the main operation or the sub operation depends on the installation situation. May be provided so that both operations can be performed.
[0037]
For example, assuming that a fire occurs from the first floor as a fire, the fire detector 11 provided there detects the fire and sends out a fire signal, and the fire signal is transmitted via the detector line 41. The fire receiving circuit 62, which is input to the fire receiving circuit 62 of the sub receiver R1 and receives the fire signal, distinguishes and detects the plurality of sensor lines 41 arranged for each area, and outputs the corresponding output to the control unit 61. Do.
[0038]
As described above, the control unit 61 that has detected the signal input (S10) confirms that a stop flag F1 described later is off in the sensor lines 41 to 4n (S11), and performs a necessary fire display ( S12), sounding is performed (S13). Then, since it is necessary to output the fire representatives (S14), it is confirmed that the transfer flag F2 is OFF (S15), and the transfer output circuit 67 is activated (S16). The flag F2 is turned on (S17), and the timer T2 is started (S18). Here, the transfer output circuit 67 closes the contact 81 and causes the output line 21 to perform the transfer output. In this representative transfer, when a fire signal is detected from any of the plurality of sensor lines 41, an output indicating fire detection is performed as the sub receiver R1 to the main receiver Rm. Here, the transfer flag F2 indicates that the representative transfer is being output, and the sub receiver R1 has detected a fire signal from another sensor line 41 during the transfer of the representative to detect the second report. In this case, the transfer of the second report is suspended. The timer T2 is a timer (not shown) built in a microcomputer or the like for measuring a predetermined time for making the one-shot output of the transfer to the output line 21. The predetermined time is set to, for example, about 30 seconds. ing.
[0039]
The main receiver Rm having received the transfer output is input to the fire receiving circuit 62 in the same manner as the sub receiver R1 receives the fire signal from the fire detector 11, and the fire receiving circuit 62 having received the transfer output is provided. Detects the detector line 41 and outputs the corresponding output to the control unit 61. The control unit 61 having detected the transfer output (S10) confirms that a stop flag F1 described later is off (S11), performs a necessary fire display (S12), and performs a sounding sound (S13). Then, there is no need to output a fire representative from the main receiver Rm (S14).
[0040]
Thereafter, when a predetermined time, here, about 30 seconds, elapses from the broadcast output, the timer T2 of the sub receiver R1 times out. When there is a time-up input of the timer T2 (S20, S21), the output of the transfer output circuit 67 is stopped (S22), and the transfer flag F2 is turned off (S23). At this time, the transfer output circuit 67 opens the contact 81 and stops the transfer output of the output line 21.
[0041]
The main receiver Rm, which has received the stop of the broadcast output, detects that the input has been stopped from the terminal where the input has been made by the fire receiving circuit 62 and sends the corresponding output to the control unit 61 in the same manner as in the case of receiving. Do. The control unit 61 that has detected the signal stop (S30) turns on the stop flag F1 (S31) and starts the timer T1 (S32). Here, the stop flag F1 indicates that the reception of the representative transfer is stopped, and cuts off the input immediately after the transfer of the representative from the sub receiver R1 is stopped. In this case, a momentary output stop due to noise may occur during one-shot output as a representative transfer, and when noise occurs, the representative output of the first report is not detected as a second report after a momentary interruption. To The timer T1 is a timer (not shown) similar to the timer T2 for measuring a predetermined time for stopping reception, and the predetermined time is set to, for example, about 10 seconds. Although not shown in detail, the stop flag F1 and the timer T1 are provided for each of the sensor lines and the transfer output lines input to the fire receiving circuit 62.
[0042]
Thereafter, when a predetermined time, here about 10 seconds, has elapsed from the stop of the reception, the timer T1 of the main receiver Rm times out. When there is a time-up input of the timer T1 (S20, S26), the stop flag F1 is turned off (S27).
[0043]
In the operation up to this point, the sub-receiver R1 that has received the fire signal and the main receiver Rm that has received the representative output thereof have sounded a fire alarm. This sounding is performed by a sound unit 65 including a not-shown buzzer and a sound synthesizing circuit (not shown) for performing sounding by sound in each of the receivers R1 and Rm, and a region arranged in each unit. The sound of the area sound is generated for the sound device 13 by the output from the control output unit 66 via the control lines 51 and 5m. In addition, the necessary district sound may be a fire monitoring district or a floor, or may be a divided sound of the fire floor and a floor immediately above or a simultaneous sound of the whole building.
[0044]
Here, when the building manager (person responsible for the similar management) of the main receiver Rm operates the sound stop switch SW1 of the operation unit 63 to perform the sound stop operation, the control of the main receiver Rm is performed. The unit 61 determines that the operation input is sound stop (S40, S41), and stops the sound unit 65, and performs a sound stop operation of stopping the output from the control output unit 66 (S42). Similarly, when the sound stop switch SW1 of the sub receiver R1 is operated, the outputs of the sound unit 65 and the control output unit 66 of the sub receiver R1 are stopped.
[0045]
When the fire continues, a fire detector 11 different from the fire detector 11 that was activated first is activated, and a second fire signal is generated. When the fire signal of the second report is input to the fire receiving circuit 62 of the sub-receiver R1 via the sensor line 41 different from that of the first report, the control unit 61 that has detected the input (S10) renews. Necessary fire display and sounding are performed (S12, S13). Then, the transfer output of the second report is confirmed that the transfer flag F2 is off (S15), the transfer output circuit 67 is activated (S16), and the transfer flag F2 is turned on (S16). S17), the timer T2 is started (S18). At this time, when the transfer flag F2 is on when outputting the transfer of the second report, the output of the second report is suspended and the input is stopped after the transfer flag F2 is turned off, although not shown in detail. After waiting for a predetermined time, for example, about 10 seconds or more, the transfer output is performed.
[0046]
The main receiver Rm that has received the transfer output of the second report is similarly input to the fire receiving circuit 62, and the control unit 61 that has detected the transfer output (S10) turns off a stop flag F1 described later. After confirming this (S11), necessary fire display and sounding are performed again (S12, S13).
[0047]
By such an operation, after the sound by the first report is stopped, when there is an input of the second report, the first report and the second report are transmitted not only in the sub receiver R1 but also in the main receiver Rm. It can be distinguished and counted individually as the number of alarms, and the sound of the fire alarm, so-called subsequent ringing, can be performed again by inputting the second alarm.
[0048]
Here, the signal input to the fire receiving circuit 62 and the timing of sounding and stopping of sound will be described with reference to FIG. In FIG. 5, (a) shows a case in which the second report sounds again and FIG. 5 (b) shows a case in which the second report is not taken. In both cases, the uppermost row shows a fire signal to the fire receiving circuit 62. The middle row shows the presence / absence of the sound sound under the control of the sound section 65 and the control output section 66, and the bottom row shows the stop input by the sound stop switch SW1 in the operation section 63.
[0049]
In FIG. 5 (a), the sound ringing is started by receiving a fire representative transfer output from the sub receivers R1 to Rn as a fire signal. Since this transfer output is a one-shot output for a predetermined time, reception stops here after about 30 seconds have elapsed. Also, the sound sound is stopped by the input of the sound stop switch SW1.
[0050]
Thereafter, when receiving the transfer output of the second report from the same sub receivers R1 to Rn, the reception has been performed for a predetermined period of time, here about 10 seconds or more, since the stop of the first report. The alarm is counted as a fire signal input again, and the sound is started again. Then, by operating the sound stop switch SW1, the sound is stopped similarly to the first report. Also, as fire information, the fact that the fire signal has been followed by a second report in addition to the first report is stored.
[0051]
On the other hand, in FIG. 5B, as in FIG. 5A, the first report is received and the sound ringing is started. When the fire signal of the first report stops once due to some influence and recovers in about 6,7 seconds, the timing of the recovery is a predetermined time after the stop of the first report, here about 10 seconds or more elapses. Here, it is determined here that the first report is continuing.
[0052]
In FIG. 5 (b), if there is no predetermined time for stopping reception, one fire signal or transfer output may be caught in a large number of alarms, such as two or three, due to the influence of noise. Would make a great movement.
[0053]
Note that, in this embodiment, the fire receiving circuit 62 is designed to retain the fire signal once received, and to adopt a method of taking in the presence or absence of the input after receiving the fire signal from the conventional method of not receiving the subsequent signal. , The subsequent, and as a result, accurate reception of the number of alarms, subsequent re-sounding, etc. are enabled. Then, in order to eliminate the influence of noise and the like, the period of reception suspension can be set, and the number of alarms can be counted accurately.
[0054]
A similar fire signal detection operation may be performed on the detector line. In the above description of the operation, regarding the representative transfer from the sub receivers R1 to Rn to the main receiver Rm, since a plurality of sensor lines 41 to 4n are provided in the sub receivers R1 to Rn, a plurality of fire signal inputs are generated. This is a case where, at a certain time, a notification output is performed for each of these inputs. Since a plurality of fire detectors 11 are connected to each of the detector lines 41 to 4n, the fire signals of these fire detectors 11 are output as one-shot outputs. By doing so, it is possible to receive fire signals from different fire detectors 11 via the detector lines 41 to 4n, and to receive a plurality of fire signals for one detector line 41 to 4n. Become a receiver. At this time, it is preferable that the one-shot output as the fire signal from the fire detector 11 is output longer than the case of the transfer output from the sub receivers R1 to Rn. Consideration must be given to ensuring reception first.
[0055]
When the fire detector outputs a one-shot fire signal, the fire signal is sent to the fire receiver as a method to reliably receive the fire signal. Alternatively, the switching operation may be stopped. That is, when the fire receiver receives a fire signal, it outputs a fire confirmation output to the line. As the fire confirmation output, it is possible to use transmission signal output, superposition of a specific frequency, power supply stop for a predetermined time, and the like. It is necessary to provide the fire detector with a receiving circuit for a transmission signal, a frequency detection circuit for a specific frequency, and a microcomputer to measure the stop period and distinguish it from a restoration signal if the power is stopped, etc. . By using these fire determination outputs, the fire detector confirms the reception of the fire signal of the destination and stops the fire signal output.
[0056]
In order to restore the system after a fire has occurred, the sub receiver R1 and the main receiver Rm, which have received the fire signal, must be restored. Here, when the manager performs the recovery operation by operating the recovery switch SW2 of the operation unit 63 of the sub receiver R1, it is determined that the operation input is recovery (S40, S43), and the sound is stopped. It is confirmed that the operation is stopped (S44). If the operation is stopped, release of holding of fire information and stop of fire display on the display unit 64 are performed as reset operations (S45), and the sound stop line 31 from the reset output circuit 68 is operated. A stop output is performed (S46). Although not described in detail, the stop output from the reset output circuit 68 is a one-shot output, and it is sufficient that the stop output be detected by the reset input circuit 69 of the main receiver Rm.
[0057]
The sound stop by the reset output circuit 68 is performed when the fire information of the sub receivers R1 to Rn of the transfer source is restored in response to the sounding of the main receiver Rm by the transfer from the sub receivers R1 to Rn. Nevertheless, if the main receiver Rm is sounding in spite of that, it is useless, so that the sound of the main receiver Rm can be stopped simultaneously with the recovery operation of the sub receivers R1 to Rn. It goes without saying that there is no problem even if the sound is stopped by operating the sound stop switch SW1 of the main receiver Rm in advance.
[0058]
When an input other than the sound stop switch SW1 and the recovery switch SW2 is input to the operation unit 63 (S40, S47), a process corresponding to the input is performed (S48).
[0059]
The fire signal and notification output to the main receiver Rm generated by the above operation are individually stored in the memory (not shown) of the control unit 61 as the number of fire information to be issued. Such fire information is displayed on the display unit 64 on the panel of the fire receiver Rm. As an example of the appearance, as shown in FIG. 3, a district window display unit 91 for each fire district and various display lights are provided. A combination of a state display section 92 and an alarm display section 93, and various switches as the operation section 63 are also shown.
[0060]
The district window display section 91 has a total of 16 windows formed in two rows, and all may be assigned to the fire district. However, in the main receiver Rm, for example, from the first to the left on the left, the sensor line 4m is provided. A plurality of district names are clearly assigned, and from the ninth to the sixteenth on the right side, they can be assigned to the output lines 21 to 2n from the respective sub receivers R1 to Rn. Then, the presence or absence of a fire, interruption, or abnormality of each line 4m or the output lines 21 to 2n can be displayed by turning on an indicator lamp.
[0061]
The status display section 92 is a representative display, in which a fire indicator light 94, a power light 95, an abnormal light 96, and the like are displayed by lighting (or blinking).
[0062]
The alert display unit 93 can perform so-called seven-segment number display at two places, and the displayed numbers are displayed as numbers corresponding to the window numbers of the district window display unit 91. The first report, which is the first report, is displayed on the left side of the number display, and the second report and subsequent reports about subsequent reports are displayed on the right side of the number display. As long as the fire information such as the third report, the fourth report, etc. exists by operating a certain subsequent switch 99, the subsequent is displayed. This subsequent display is only for the second and subsequent reports, and the first report is fixed on the left side.
[0063]
For example, when there is a representative transfer from the sub receiver R1, it is determined that a fire has occurred on the first floor, and a fire indicator lamp corresponding to the ninth window is turned on in the district window display section 91, and at the same time, the alarm display section 93 is displayed. "09" is displayed on the left side, which is the first report (FIRST). Next, when there is an input corresponding to the district window No. 1 as a fire signal from the detector line 4m of the main receiver Rm as a subsequent signal, the fire indicator lamp corresponding to the window No. 1 is turned on in the district window display section 91. At the same time, "01" is displayed on the right side, which is the last (LAST) of the alarm display section 93. As described above, the numbers used for the alert display correspond to the numbers of the district windows.
[0064]
As a third report, when there is a subsequent representative transfer output from the sub receiver R1, there is no change in the district window display section 91, but when the subsequent switch 99 is operated, the right side of the report display section 93 becomes " 01 ”to“ 09 ”. Then, for example, when the fourth report is “10”, “09” becomes “10” by operating the subsequent switch 99 again, and if there is further operation of the subsequent switch 99 and there is no fifth report, the second report is issued. It returns, and it changes from "10" to "01".
[0065]
As described above, the main receiver Rm can also receive the subsequent transmission as the representative transmission of the sub receivers R1 to Rn, so that the number of alarms can be counted for each district. Although the main receiver Rm itself does not know the alerting line of the sub receivers R1 to Rn, information on the number of alerts can be obtained from the sub receivers R1 to Rn. If it is found that a plurality of data have been input, the information may be confirmed by going to the sub receivers R1 to Rn.
[0066]
A similar fire signal detection operation may be performed on the detector line. In the above description of the operation, regarding the representative transfer from the sub receivers R1 to Rn to the main receiver Rm, the detector line 41 is connected to the sub receivers R1 to Rn. When there are a plurality of fire signal inputs, a plurality of fire signals are output for each of these inputs. A plurality of fire detectors 11 are provided in each of the detector lines 41 to 4n.
