JP 2008-004033 A

  For example, in the case of a fire alarm repeater, the fire alarm device as described above is often installed in the vicinity of a housing information panel (interphone) or the like. For this reason, when an alarm sound or the like is generated from the fire alarm device, a plurality of devices (devices) that perform a fire alarm are installed at positions close to each other, and the alarm sound interferes. For example, in the case of voice or the like, the user cannot hear the content, and rather hinders notification. The same applies to, for example, fire alarms, fire alarm devices, and fire alarms.

  Therefore, an object of the present invention is to obtain a fire alarm device and a fire alarm system that can improve convenience without impeding recognition of an alarm by a user.

The fire alarm device according to the present invention is a fire alarm device capable of generating a warning sound based on a radio signal from a fire alarm device in a fire alarm system, and detecting a fire and issuing a fire alarm. Fire alarm sound output setting means that sets whether or not to generate an alarm sound related to fire when a fire alarm signal related to fire is received, and a fire alarm sound output setting means that generates an alarm sound related to fire In the case of setting, when an alarm signal related to a fire is received from a fire alarm device, an alarm sound generating means for generating an alarm sound related to the fire and an instruction to stop the alarm related to the fire of the fire alarm device are input. And an alarm stop instruction input means for switching between valid and invalid of the instruction input from the alarm stop instruction input means based on the setting of the fire alarm sound output setting means. When the means is set to generate an alarm sound related to fire, the instruction input from the alarm stop instruction input means is validated and an alarm stop signal for stopping the alarm related to the fire of the fire alarm is transmitted. If the fire alarm sound output setting means is set so that the fire alarm sound output setting means does not generate a fire alarm sound, the instruction input from the alarm stop instruction input means is invalidated and the fire alarm fires. An alarm stop signal for stopping the alarm is not transmitted.

In addition, the fire alarm system of the present invention includes one or more fire alarms and one or more fire alarm devices, and the fire alarm performs a fire alarm and detects a fire when a fire is detected. The alarm signal related to fire is transmitted by radio, and when the alarm signal related to fire from other fire alarms is received, the alarm related to fire is performed, and the device for fire alarm is the alarm signal related to fire from the fire alarm In a fire alarm system that can generate an alarm sound based on the above, the fire alarm device sets whether to generate an alarm sound related to a fire when receiving an alarm signal related to a fire from a fire alarm When the fire alarm sound output setting means and the fire alarm sound output setting means are set to generate a fire alarm sound, when the fire alarm signal from the fire alarm is received, the fire alarm sound Raised And an alarm stop instruction input means for inputting an instruction to stop an alarm related to a fire of the fire alarm, and based on the setting of the fire alarm sound output setting means, an alarm stop instruction input means If the fire alarm sound output setting means is set to generate an alarm sound related to a fire, the instruction input from the alarm stop instruction input means is validated and fire is set. Sends an alarm stop signal to stop the alarm related to the fire of the alarm device, stops the alarm sound related to the fire, and if the fire alarm sound output setting means is set not to generate the alarm sound related to the fire, the alarm The instruction input from the stop instruction input means is invalidated, and the fire alarm does not send an alarm stop signal to stop the fire alarm, and the fire alarm receives the alarm stop signal. If, but to stop the alarm relating to a fire.

In addition, the fire alarm system of the present invention includes one or more fire alarms and one or more fire alarm devices, and the fire alarm performs a fire source alarm and detects a fire when a fire is detected. This alarm signal is transmitted wirelessly, and when an alarm signal related to fire is received from another fire alarm device, an interlocking alarm is given, and the fire alarm device warns based on the alarm signal related to fire from the fire alarm device. In a fire alarm system capable of generating sound, the fire alarm device sets whether to generate an alarm sound related to fire when receiving an alarm signal related to fire from a fire alarm device When the setting means and the fire alarm sound output setting means are set to generate an alarm sound related to a fire, an alarm that generates an alarm sound related to a fire when receiving an alarm signal related to a fire from a fire alarm Sound And an interlocking alarm stop instruction input means for inputting an instruction to stop the interlocking alarm of the fire alarm device, and input from the interlocking alarm stop instruction input means based on the setting of the fire alarm sound output setting means If the fire alarm sound output setting means is set to generate a fire alarm sound, the instruction input from the interlock alarm stop instruction input means is validated and the fire alarm Sends an interlocking alarm stop signal to stop the interlocking alarm, stops the alarm sound related to the fire, and inputs the interlocking alarm stop instruction when the fire alarm sound output setting means is set not to generate the alarm sound related to the fire The instruction input from the means is invalidated, the interlock alarm stop signal for stopping the interlock alarm of the fire alarm is not transmitted, and the fire alarm receives the interlock alarm stop signal. If is intended to stop the linked alarm.

In the fire alarm system of the present invention , the fire alarm device includes an alarm stop switch. When the alarm stop switch is operated, the fire alarm or the interlock alarm is stopped and the interlock alarm stop signal is transmitted, The alarm device is equipped with a transfer output unit that outputs a transfer signal to an external device when it receives an alarm signal related to a fire from a fire alarm device. When an alarm stop signal is received, the output of the transfer signal by the transfer output unit is stopped, and when the interlocked alarm stop signal is received from the fire alarm that performs the interlocking alarm, the output of the transfer signal by the transfer output unit is stopped. It will continue without letting it.

The fire alarm system according to the present invention is a fire alarm repeater that relays between the fire alarm system and an external device and / or a flashlight device that emits flash light based on a radio signal from the fire alarm. .

  According to the present invention, the fire alarm sound output setting means is provided, and the generation of the alarm sound by the fire alarm device can be arbitrarily set when a fire alarm signal is received from the fire alarm. For this reason, when the distance from other devices that generate an alarm sound is short depending on the installation status of the fire alarm device, interference is prevented by not generating an alarm sound, without interfering with each other. Since the user can recognize the alarm, convenience can be enhanced.

  In addition, since the instruction of the alarm stop instruction input means can be switched between valid and invalid based on the setting of the fire alarm sound output setting means, the instruction from the instruction input in the device that does not generate the alarm sound is invalidated. be able to.

  In addition, since only the fire alarm sound can be set, other sounds such as a sound for notifying abnormality can be generated regardless of the setting.

  In addition, for example, a fire alarm repeater that may be installed in the same room as a fire alarm, an external device, etc., or a flashlight device that emits flash light is used as the above fire alarm device. An alarm can be recognized, and convenience can be improved.

  And since the above fire alarm devices were systemized together with a fire alarm device, a highly convenient fire alarm system can be obtained.

FIG. 3 is a diagram for illustrating a circuit configuration of the repeater 30 and the like. It is a figure showing the flowchart of the alarm process which concerns on the fire of the fire alarm device. It is a figure showing the flowchart of the alarm process which concerns on the fire of the repeater.

Embodiment 1 FIG.
FIG. 1 is a diagram showing a configuration of a fire alarm system according to Embodiment 1 of the present invention. The fire alarm system of the present embodiment includes one or a plurality of fire alarms 10 and one or a plurality of fire alarm repeaters 30 (hereinafter referred to as repeaters 30) that serve as a fire alarm device. In the system, a group is configured by devices that can transmit and receive radio signals. In the present embodiment, one parent fire alarm 10 is provided in the group, and the remaining devices are children. . In FIG. 1, the system has one group. For example, a plurality of groups can be configured in the system. Moreover, although not specifically limited, the fire alarm device 10 as a parent is basically provided at a position where it can communicate with all devices in the group. When an alarm signal or the like is received from another fire alarm device 10 or the like, it is retransmitted to other devices in the group so as to be reliably linked. For example, each device in the group has an address uniquely set in the group in order to specify the communication source and the communication destination.

  For example, when the fire alarm 10 detects a fire or the like, the fire alarm 10 gives an alarm by sound, display, etc., and notifies a user (for example, a resident). In addition, when an alarm signal relating to a fire is received from another fire alarm device 10 in the group, an alarm is issued in conjunction. Here, the fire alarm device 10 of the present embodiment has a function of checking whether or not the devices in the group can be interlocked and alarmed by a user operation.

  The repeater 30 is a device that performs relay when communicating with an external device in order to transfer (output) a signal related to the fire of the fire alarm system to an external device (including an external system). The repeater 30 of the present embodiment does not have a function of detecting a fire or the like, but can perform an alarm in conjunction with the signal from the fire alarm 10. Also, a unique address is set in the repeater 30 as in the case of the fire alarm device 10, and is treated as a child device in communication.

  FIG. 2 is a diagram for illustrating a circuit configuration and the like of the fire alarm device 10 according to the embodiment of the present invention. In FIG. 2, a fire alarm 10 includes a control circuit 1, a battery 2, a power supply circuit 3, a battery voltage detection circuit 4, a transmission / reception circuit 5, an antenna 6, a fire detection circuit 7, an alarm sound control circuit 8, a display circuit 9, and an inspection. An alarm stop switch 20 is provided.

  The control circuit 1 performs processing based on an input signal or the like, and controls a circuit or the like included in the fire alarm 10. For example, on the basis of a signal from the fire detection circuit 7, the alarm sound control circuit 8 and the display circuit 9 are operated to perform an alarm relating to fire by sound and display. Communication processing with other devices in the system (group) is performed via the transmission / reception circuit 5. The storage element 21 is, for example, a nonvolatile memory such as an EEPROM, and stores various data such as a program related to processing executed by the control circuit 1, addresses set in itself and other devices in the group, and group ID of the group to which it belongs. Storing.

  The battery 2 supplies DC power to the power supply circuit 3. The power supply circuit 3 controls the voltage of the battery 2 to a predetermined voltage and supplies it to each circuit of the fire alarm 10. The battery voltage detection circuit 4 detects a voltage related to the application of the battery 2 and outputs a battery voltage detection signal corresponding to the detected voltage to the control circuit 1.

  When it is determined that the remaining battery level is low or the battery depletion threshold value is exceeded based on the voltage detection signal from the battery voltage detection circuit 4, the control circuit 1 drives the alarm sound control circuit 8 and the display circuit 9. To let you know when the battery is dead.

  The transmission / reception circuit 5 is connected to an antenna 6 for transmitting / receiving a radio signal. The transmission / reception circuit 5 processes a radio signal input (sent) via the antenna 6 and includes its own address as communication destination data (including cases where all addresses are used as communication destinations). If it is determined, the reception process is performed. If it is determined that the radio signal is other than its own address, the reception process is not performed. The received signal is output to the control circuit 1. In addition, the transmission / reception circuit 5 performs transmission processing of a state signal and the like related to processing of the control circuit 1.

  The fire detection circuit 7 detects a physical change such as smoke or heat based on the fire phenomenon and outputs a signal corresponding to the detected content to the control circuit 1. Here, it demonstrates as what outputs the signal which concerns on the detection of fire, without distinguishing in particular in detail.

  The alarm sound control circuit 8 is a circuit for controlling an operation for generating an alarm sound from a buzzer / speaker or the like (not shown). The display circuit 9 is a circuit that controls the lighting operation of an indicator lamp such as a light emitting diode. Here, although it demonstrates as what is a circuit which performs lighting control of an indicator lamp, for example, when fire alarm 10 has a display means which can display a character, a number, etc., control which displays a character etc. May be performed.

  The inspection / alarm stop switch 20 serving as an instruction input means is a switch that is pressed by the user to cause the fire alarm 10 to perform interlocked inspection. Moreover, although it can also be set as another structure, in this Embodiment, at the time of the alarm which concerns on a fire, it shall also serve as the switch for a user to stop the alarm which concerns on a fire. Furthermore, the switch can be used properly by distinguishing, for example, half-pressing, full-pressing, short-pressing, long-pressing, or the like.

  FIG. 3 is a diagram for illustrating a circuit configuration and the like of the repeater 30 according to the embodiment of the present invention. In FIG. 3, the repeater 30 is similar to the fire alarm 10 in that it includes a control circuit 31, a battery 32, a power supply circuit 33, a battery voltage detection circuit 34, a transmission / reception circuit 35, an antenna 36, an alarm sound control circuit 38, and a display circuit 39. And an inspection / alarm stop switch 41. These circuits and the like basically perform the same operations as the corresponding circuits and the like of the fire alarm 10 described above. However, the control circuit 31 may perform processing different from the processing of the control circuit 1 of the fire alarm device 10 due to the difference in roles in the system. The control circuit 31 has a storage element 44 and stores various data such as a program for processing executed by the control circuit 31 and addresses set for itself and other devices in the group. And unlike the fire alarm device 10, since it does not detect a fire etc., the repeater 30 of this Embodiment shall not have the circuit corresponding to the fire detection circuit 7. FIG.

  Further, the repeater 30 of the present embodiment has a message output unit 40, a fire alarm sound output setting switch 42, and a message output setting switch 43. The transfer output unit 40 is configured to output (transmit) a transfer signal including an alarm signal related to a fire to an external device outside the system. The transfer output unit 40 is wired to an external device or the like, but may be wirelessly connected.

  The fire alarm sound output setting switch 42 is a switch (setting means such as a dip switch) for setting whether or not an alarm sound is generated in the repeater 30. Here, the fire alarm sound output setting switch 42 is set for the generation of an alarm sound (fire alarm sound). For this reason, the repeater 30 of the present embodiment is not related to the setting of the fire alarm sound output setting switch 42 for other sounds (for example, sounds related to abnormality notifications such as battery exhaustion, sensor abnormality, communication abnormality, etc.). Shall be generated. Also, the setting change by the fire alarm sound output setting switch 42 of the present embodiment becomes effective when the power is turned on and reset by a reset button (not shown) or the like. For this reason, it is assumed that the setting is not changed even when the switch is switched during normal operation.

  The transfer output setting switch 43 serving as a transfer output setting means is a switch for setting whether or not to output a transfer signal from the transfer output unit 40, for example, during linked inspection. Here, the transfer output setting means is constituted by a switch, but it is not particularly limited to the switch, for example, the setting made in accordance with the request is stored in the storage element 44 as a database. The same applies to the fire alarm sound output setting switch 42.

  In the present embodiment, when a fire alarm sound output setting switch 42 is provided in the repeater 30 in the fire alarm system and a fire alarm signal is received from the fire alarm device 10, the presence or absence of an alarm due to the occurrence of a fire alarm sound is particularly detected. It can be set. Here, in the fire alarm sound output setting switch 42 of the present embodiment, since only the fire alarm sound can be set, for example, a sound related to abnormality notification is generated regardless of the setting. .

  Further, based on the setting in the fire alarm sound output setting switch 42, the processing when the inspection / alarm stop switch 41 is pressed at the time of an alarm relating to a fire is changed, and the user operates the inspection / alarm stop switch 41. Even if the operation is performed, the operation for stopping the alarm sound of other devices can be invalidated.

  FIG. 4 is a diagram illustrating a flowchart of alarm processing relating to a fire of the fire alarm device 10 according to the embodiment of the present invention. Next, based on FIG. 4, the alarm process which concerns on the fire which the control circuit 1 of the fire alarm device 10 performs is demonstrated.

  First, it is determined whether or not a signal is input from the fire detection circuit 7 (S1). If it is determined that a signal due to fire detection has been input, the place where it is installed becomes the fire alarm 10 of the fire source. Accordingly, the alarm sound control circuit 8 is operated to generate a sound or the like indicating that the fire is a fire, and the display circuit 9 is operated to display a fire source alarm for displaying the fire (S2). . Then, the transmission / reception circuit 5 is caused to transmit an interlock control signal for interlocking the alarm to other devices in the group via the antenna 6 (S3).

  On the other hand, if it is determined in S1 that a fire detection signal is not input from the fire detection circuit 7, it is determined whether an interlock control signal is received from another device via the antenna 6 and the transmission / reception circuit 5 ( S4). If it is determined that the interlock control signal has been received, the alarm sound control circuit 8 is operated to generate a sound indicating a fire at another location, and the display circuit 9 is operated to display a fire. An interlocking alarm is performed (S5). If it is determined that the interlock control signal has not been received, the process returns to S1, and determination of signal input from the fire detection circuit 7 and reception of the interlock control signal is performed at predetermined time intervals.

  Then, after giving an alarm, it is determined whether the inspection / alarm stop switch 20 is pressed and an instruction to stop the alarm is given (S6). If it is determined that the inspection / alarm stop switch 20 is pressed, the generation of sound by the alarm sound control circuit 8 and the display by the display circuit 9 are stopped, and the fire source alarm or the interlocking alarm is stopped (S7). And the transmission / reception circuit 5 is made to transmit the interlocking alarm stop signal for stopping the interlocking alarm of another apparatus via the antenna 6 (S8), and it returns to S1 and processes again.

  If it is determined in S6 that the inspection / alarm stop switch 20 has not been pressed, it is determined whether or not an interlocking alarm stop signal from another device has been received via the antenna 6 and the transmission / reception circuit 5 (S9). If it is determined that the interlock alarm stop signal has been received, the generation of sound by the alarm sound control circuit 8 and the display by the display circuit 9 are stopped, the interlock alarm is stopped (S10), and the process returns to S1 and the process is performed again. At this time, since only the interlock alarm is stopped, the fire alarm is not stopped in the fire alarm device 10 that performs the fire alarm. If it is determined that the interlocking alarm stop signal from another device has not been received, the process returns to S6 and an alarm is issued until the inspection / alarm stop switch 20 is pressed or a interlocking alarm stop signal from another device is received. continue.

  By performing the above processing, when the inspection / alarm stop switch 20 is pressed in the fire alarm 10 related to the fire source alarm, the own fire source alarm and the interlocking alarm in other devices are stopped. On the other hand, when the inspection / alarm stop switch 20 is pressed in the fire alarm device 10 related to the interlock alarm, the interlock alarm in the self and other devices stops (the fire alarm does not stop).

  FIG. 5 is a diagram illustrating a flowchart of alarm processing related to a fire of the repeater 30 according to the embodiment of the present invention. Next, based on FIG. 5, the alarm process regarding the fire which the control circuit 31 of the repeater 30 performs is demonstrated.

  First, it is determined whether an interlock control signal has been received from another fire alarm 10 or the like via the antenna 36 and the transmission / reception circuit 35 (S21). If it is determined that the interlock control signal has not been received, the determination of the interlock control signal reception is performed at predetermined time intervals.

  If it is determined that the interlock control signal has been received, it is determined whether or not the fire alarm sound output setting switch 42 is turned on (S22). If it is determined that the alarm signal is on, the alarm sound control circuit 38 and the display circuit 39 are operated to issue a linked alarm (S23). Further, the alarm output unit 40 is made to output an alarm alarm signal related to the fire (S24).

  On the other hand, if it is determined that the fire alarm sound output setting switch 42 is not turned on (turned off), the interlocking alarm is not performed, and the transition output unit 40 is caused to output a transition signal related to the fire alarm. Here, the interlock alarm is not performed when the fire alarm sound output setting switch 42 is OFF, but only the display circuit 39 may be operated to perform the alarm only for display. With this configuration, it is possible to respond to a user's request that it is desired to avoid the alarm sound from interfering but only to confirm the display.

  Then, it is determined whether the inspection / alarm stop switch 41 is pressed and an instruction to stop the alarm is given (S25). If it is determined that the inspection / alarm stop switch 41 is pressed, it is further determined whether or not the fire alarm sound output setting switch 42 is turned on (S26). If it is determined that it is on, the generation of sound by the alarm sound control circuit 38 and the display by the display circuit 39 are stopped, and the interlocking alarm is stopped (S27). Then, the transmission / reception circuit 35 is caused to transmit an interlocking alarm stop signal for stopping the interlocking alarm of another device via the antenna 36 (S28). On the other hand, the transfer output unit 40 continues to output the alarm transfer signal related to the fire (S29).

  On the other hand, if it is determined that the fire alarm sound output setting switch 42 is not turned on (is turned off), the interlocking alarm stop signal is not transmitted to the transmission / reception circuit 35, and the transfer output unit 40 is fired. Only the alarm signal is output continuously (S29). Thereby, when the fire alarm sound output setting switch 42 is off, even if the user presses the inspection / alarm stop switch 41, the operation becomes invalid. In addition, when performing the interlock alarm only for a display when the fire alarm sound output setting switch 42 is OFF, the interlock alarm only for a display is stopped. With this configuration, it is possible to respond to a user's request that it is desired to avoid the alarm sound from interfering but only to confirm the display.

  If it is determined in S25 that the inspection / alarm stop switch 41 has not been pressed, it is determined whether an interlocked alarm stop signal from another device has been received via the antenna 36 and the transmission / reception circuit 35 (S30). . If it is determined that the interlock alarm stop signal has been received, it is further determined whether or not the fire alarm sound output setting switch 42 is turned on (S31). If it is determined that it is turned on, the generation of sound by the alarm sound control circuit 38 and the display by the display circuit 39 are stopped, and the interlocking alarm is stopped (S32). On the other hand, if it is determined that the switch is not turned on (turned off), the next process is performed without performing the process related to the interlocking alarm. In addition, when performing the interlock alarm only for a display when the fire alarm sound output setting switch 42 is OFF, the interlock alarm only for a display is stopped.

  Next, based on the interlocking alarm stop signal related to reception, it is determined whether or not the signal transmission source is the fire alarm device 10 related to the fire source (S33). If it is determined that the fire alarm device 10 is related to the fire source, the transfer output unit 40 stops the output of the signal related to the fire alarm (S34), and the process returns to S21 to perform the process again. If it is determined that it is not the fire alarm device 10 related to the fire source, the transfer output unit 40 is made to continuously output the alarm transfer signal related to the fire (S29). Whether or not the fire alarm device 10 is a fire source can be determined by whether or not the address of the transmission source of the interlock control signal is the same.

  As described above, according to the repeater 30 that is the fire alarm device in the first embodiment, the fire alarm sound output setting switch 42 is provided, and when a fire alarm signal is received from the fire alarm 10, the repeater The generation of an alarm sound by 30 can be arbitrarily set. For this reason, for example, the user can make settings according to the installation status of the repeater 30, for example, the distance from other devices (such as fire alarm 10 and external devices in the repeater 30) that generate an alarm sound. In such a case, by preventing the alarm sound from being generated, interference and the like can be prevented and the user can recognize the alarm, so that convenience can be improved.

  At this time, by making it possible to set only the fire alarm sound, other sounds such as a sound for notifying an abnormality can be generated regardless of the setting.

  Further, when the inspection / alarm stop switch 41 is pressed at the time of an alarm relating to a fire, and the setting in the fire alarm sound output setting switch 42 is OFF, the transmission / reception circuit 35 is not transmitted with an interlocking alarm stop signal. In addition, since the transfer output unit 40 continues to output the transfer signal, even if the user operates the inspection / alarm stop switch 41, the operation is invalidated, and the repeater 30 It is possible to prevent the interlocking alarm from being stopped.

  By configuring the repeater 30 as a fire alarm device as described above as a system together with the fire alarm device 10, a highly convenient fire alarm system can be obtained.

Embodiment 2. FIG.
In Embodiment 1 mentioned above, the repeater 30 was shown as an example as a fire alarm device. However, the present invention is not limited to this. For example, a device having another function and installed in the same room as the fire alarm 10 may be used as the fire alarm device. For example, there is a flashlight device that emits flash light upon receiving an interlock control signal, thereby giving a fire alarm. The flashlight device can visually recognize an alarm without generating an alarm sound. Also, a device such as a relay that relays signals between groups in the fire alarm system can be used as a fire alarm device. Thus, a device having another function can be used as a fire alarm device.
