(1) Overview Each drawing described in the following embodiments is a schematic drawing, and the ratio of the size and thickness of each component in each drawing does not necessarily reflect the actual dimensional ratio. Not necessarily.

As shown in FIG. 2, the alarm system 100 according to the present embodiment includes a plurality of alarm devices 1 (three in the illustrated example) and at least one external device 2 (one in FIG. 2). there is Further, as shown in FIG. 2, the alarm device 1 according to the present embodiment can transmit and receive interlocking signals for interlocking alarm sounds with at least one other alarm device 1 (two in the illustrated example). It is possible.

The alarm device 1 is, for example, a so-called composite device (emergency alarm equipment) provided with an emergency power supply 13 (see FIG. 1). The alarm device 1 is installed directly or embedded in a wall or the like in a facility such as a building. The alarm device 1 operates, for example, by power supply from a commercial AC power supply 3 (see FIG. 2, for example, effective value 100 V). , and operates by power supply from the built-in emergency power supply 13 .

The alarm device 1 includes an operation section 11, a control section 12, and a sound output section 14 (see FIGS. 1 and 2).

The operation unit 11 receives a push operation from the outside. The operation unit 11 receives a push operation from a user who uses the facility, for example, when an abnormality such as a fire occurs in the facility.

The control unit 12 outputs an alarm signal when the operation unit 11 receives a push operation or receives an interlocking signal from another alarm device 1 . The sound output unit 14 outputs a notification sound in response to the notification signal. The alarm device 1 can be electrically connected to an external device 2 that executes processing related to notification of an abnormality when an instruction signal is received. The control unit 12 outputs an instruction signal to the external device 2 at least when the operation unit 11 receives a pressing operation. In other words, if the external device 2 is connected to the alarm device 1, the alarm device 1 causes the external device 2 to execute the processing related to the notification of abnormality when the operation unit 11 of the device receives the push operation. In the following description, when a certain alarm device 1 is focused on, the fact that the operation unit 11 of the alarm device 1 (own device) receives a push operation may be referred to as occurrence of a "first event".

Here, even when the interlocking signal is received, the control unit 12 performs the interlocking output of the instruction signal to the external device 2 so as to interlock with the interlocking signal. That is, even if the first event has not occurred, the control unit 12 causes the external device 2 to Execute the processing related to the error notification. In the following, when focusing on a certain alarm device 1, receiving an interlocking signal from another alarm device 1 in a situation where the first event has not occurred may be referred to as occurrence of a "second event." .

According to this configuration, even if the first event does not occur, if the second event occurs (receipt of the interlocking signal), the external device 2 can be caused to execute the process regarding the abnormality notification. Therefore, depending on the type of the external device 2, the necessity of wiring between the alarm devices 1 for transferring the alarm to the external device 2 can be suppressed. Therefore, workability can be improved.

(2) Details (2.1) Overall Configuration Hereinafter, the overall configuration of the alarm device 1 according to the present embodiment and the alarm system 100 including a plurality of alarm devices 1 will be described in detail. The alarm system 100 further includes at least one external device 2 (one in FIG. 2). Hereinafter, when distinguishing the three alarm devices 1 from each other, they may also be referred to as an alarm device 1A, an alarm device 1B, and an alarm device 1C in order from the left side in FIG. The alarm system 100 is configured to enable transmission and reception of an interlocking signal for interlocking alarm sounds between a plurality of alarm devices 1 .

Also, the alarm device 1 can be electrically connected to an external device 2 . The (control unit 12 of) the alarm device 1 is configured to output an instruction signal to the external device 2 at least when the operation unit 11 of the own device receives the push operation (occurrence of the first event). In other words, although the external device 2 is not necessarily connected to each alarm device 1, if the external device 2 is connected to a certain alarm device 1, the certain alarm device 1 can operate its own device. When the unit 11 is pressed, an instruction signal is output to the external device 2 connected to the device itself.

As described above, the alarm device 1 includes the operation section 11, the control section 12, the emergency power supply 13, and the sound output section 14 (see FIG. 1). The alarm device 1 further includes a display lamp 4 , an inspection reception section 15 , a display section 16 , a housing 18 (see FIG. 2), and a storage section 19 . The alarm device 1 further includes circuit modules such as a power supply circuit and a lighting circuit. The alarm device 1 also comprises a terminal block 5 (see FIG. 3A).

The alarm device 1 operates by power supply from an AC power supply 3 (see FIG. 2) during normal times (when there is no power failure), and operates by power supply from an emergency power supply 13 during power failures. The emergency power supply 13 includes one or more batteries (secondary batteries). The power supply circuit normally converts AC power from the AC power supply 3 into DC power to generate operating power for the alarm device 1 . Also, the power supply circuit normally charges the battery of the emergency power supply 13 with power supplied from the AC power supply 3 . The power supply circuit also switches the main power supply from the AC power supply 3 to the emergency power supply 13 in the event of a power failure, and uses the DC power discharged from the emergency power supply 13 to generate operating power for the alarm device 1 . The alarm device 1 has an inspection function for checking whether the battery voltage of the emergency power supply 13 is normal or abnormal, and operates by power supply from the emergency power supply 13 even during execution of the inspection function. The lighting circuit is configured to light the light sources such as the indicator lamp 4 and the display unit 16 using the operating power generated by the power supply circuit.

FIG. 2 is a schematic front view of each alarm device 1 installed on a wall of a facility or the like. In the following description, the up-down direction and left-right direction of the alarm device 1 are defined based on the up-down direction and left-right direction of the alarm device 1 installed on the wall (see FIG. 2). The front surface (front) of the alarm device 1 is the surface on which the display lamp 4, the operation unit 11, and the sound output unit 14 are located, and the rear surface of the alarm device 1 is the surface on the wall side.

The housing 18 is, for example, a vertically long, flat rectangular box. The housing 18 has a front cover and a rear case, and the cover is detachable from the case. The housing 18 includes the display lamp 4, the operation unit 11, the control unit 12, the emergency power supply 13, the sound output unit 14, the inspection reception unit 15, the display unit 16, the terminal block 5, and circuits such as a lighting circuit and a power supply circuit. Modules are housed internally or supported on the front. The housing 18 has, for example, a through hole on its rear surface or side surface for introducing a power line L0 (see FIG. 2) electrically connected to the AC power supply 3 therein.

The operation unit 11 is a push button that receives a push operation from a user (outside) who uses the facility, for example, when an abnormality such as a fire occurs in the facility. The operation unit 11 is arranged on the lower side of the front surface of the housing 18 . A notification sound is output from the sound output unit 14 when the operation unit 11 receives a push operation.

The indicator light 4 has a light source (for example, LED: Light Emitting Diode) and a dome-shaped cover that covers the front of the light source. The cover has translucency. The indicator lamp 4 is arranged on the upper side of the front surface of the housing 18 . The indicator lamp 4 is always lit so as to clearly indicate the position of the alarm device 1 even in the dark.

The sound output unit 14 is, for example, an acoustic device including a speaker and an acoustic circuit. The sound output unit 14 is housed inside the housing 18 . However, the speaker of the sound output unit 14 is positioned substantially at the center in the vertical direction when viewed from the front of the housing 18 . The housing 18 has, in the center of the front surface, a plurality of acoustic holes through which the notification sound output from the sound output section 14 is led out. The acoustic circuit of the sound output section 14 outputs a notification sound in response to the notification signal (alarm signal) received from the control section 12 . The notification sound is stopped by pressing a recovery push button provided on the front surface of the housing 18 .

The inspection accepting unit 15 accepts an operation for performing an operation inspection by power supply from the emergency power supply 13 . The inspection reception unit 15 is composed of, for example, push buttons. The inspection reception unit 15 is provided, for example, on the front surface of the housing 18 at a position on the right side immediately below the acoustic hole (see FIG. 2). When an inspector who inspects the alarm device 1 presses the inspection reception unit 15, an operation inspection such as whether or not the alarm sound is normally output is executed. In particular, the inspector can confirm whether the battery voltage of the emergency power supply 13 is normal or abnormal through this operation inspection.

The display unit 16 is configured to display abnormal results such as the occurrence of fire, inspection results, and the like. The display unit 16 includes an AC power supply lamp 161, a battery confirmation lamp 162, a display panel 163, and the like, as shown in FIG. Under the control of the control unit 12, the AC power supply lamp 161 lights green, for example, when the AC power supply 3 is normal (no power failure), and turns off when abnormal (power failure). Under the control of the control unit 12, the battery check lamp 162 lights up in green, for example, if the battery voltage of the emergency power supply 13 is normal, and lights up, for example, in red if the battery voltage of the emergency power supply 13 is abnormal. The display board 163 is composed of, for example, a liquid crystal display. Under the control of the control unit 12, when the operation unit 11 receives a push operation when an abnormality such as a fire occurs, the display panel 163 receives text information (for example, "Fire broke out") for notifying the occurrence of an abnormality such as a fire. etc.). Further, the display panel 163 may display character information such as "battery test normal" or "battery test abnormal" according to the result of the operation check.

The terminal block 5 has a pair of power terminals 50, a pair of first terminals 51 (interlocking terminals), and a pair of second terminals 52 (non-voltage terminals), as shown in FIG. 3A. These terminals 50 to 52 are, for example, screw terminals. 3A shows the terminal block 5 of the leftmost alarm device 1A and the terminal block 5 of the center alarm device 1B in FIG.

As shown in FIG. 3A, the pair of power terminals 50 are connected to two power lines L0 (an L-pole side power line and an N-pole side power line), respectively. In FIG. 2, one power supply line L0 is schematically illustrated. A plurality of alarm devices 1 receive power supply from an AC power supply 3 by being connected by a transition wiring system via two power lines L0.

The first terminal 51 is a terminal connected to another alarm device 1 via a first signal line L<b>1 to transmit or receive an interlocking signal to the other alarm device 1 . As shown in FIG. 3A, two first signal lines L1 are connected to the pair of first terminals 51, respectively. In FIG. 2, one first signal line L1 is schematically illustrated. A plurality of alarm devices 1 are connected by a transition wiring method via two first signal lines L1.

The second terminal 52 is a terminal that is connected to the external device 2 via the second signal line L2 and outputs an instruction signal to the external device 2 . In FIG. 2, one second signal line L2 is schematically illustrated. When the external device 2 receives the instruction signal from the alarm device 1, the external device 2 executes processing related to notification of abnormality. As shown in FIGS. 2 and 3A, the external device 2 is a report station 21 that reports the occurrence of an abnormality such as a fire to a predetermined report destination (for example, a fire department such as a fire station) in response to receiving an instruction signal. It is assumed that there is, but it could also be an external buzzer 22 (see FIG. 3B) with a lamp. Alternatively, the external device 2 may be a (sub)receiver provided with a display or the like for displaying which of the plurality of alarm devices 1 has its operation unit 11 pressed.

When the external device 2 is the reporting station 21, the "processing related to notification of anomaly" is, for example, a process of transmitting a notification signal for notifying the occurrence of an abnormality such as a fire using a telephone line. The report signal includes, for example, a pre-recorded message containing the address and name of the reporting facility. When the external device 2 is the external buzzer 22, the "process regarding abnormality notification" is lamp lighting processing and buzzer alarm processing. For example, by turning on the lamp of the external buzzer 22, it is possible to notify the surrounding people of which operation unit 11 of the alarm device 1 has been pressed.

For example, the pair of second terminals 52 of the alarm device 1A can be connected to the reporting station 21 via two second signal lines L2 as shown in FIG. 3A. A switch SW<b>1 that opens and closes the relay contact (a contact) is provided in the electric path between the pair of second terminals 52 .

The control unit 12 has, for example, a computer system having a processor and memory. The computer system functions as the control unit 12 by the processor executing the program stored in the memory. The program executed by the processor is recorded in advance in the memory of the computer system here, but may be recorded in a non-temporary recording medium such as a memory card and provided, or may be provided through an electric communication line such as the Internet. may be

The control unit 12 is configured to control a power supply circuit, a lighting circuit, an acoustic circuit of the sound output unit 14, and the like. The control unit 12 also has an image processing function for generating an image to be displayed on the display panel 163 . In particular, when the operation unit 11 receives a push operation (occurrence of the first event), the control unit 12 outputs an alarm signal (alarm signal) to the acoustic circuit or the like of the sound output unit 14 in order to output an alarm sound. Output. The acoustic circuit of the sound output unit 14 causes the speaker to output a notification sound in response to the notification signal.

The notification sound includes a siren sound (warning sound). The notification sound is, for example, a repeated siren sound "woo". The notification sound may include an audio sound including a voice message (audio alarm) in addition to the siren sound. Audio sounds may include, for example, a voice message saying "There is a fire". The notification sound may consist of, for example, repeating "Woo-ooh, it's a fire, it's a fire". The storage unit 19 stores various types of information such as sound data relating to siren sounds and voice sounds. The storage unit 19 is composed of a device selected from ROM (Read Only Memory), RAM (Random Access Memory), EEPROM (Electrically Erasable Programmable Read Only Memory), or the like.

Further, the control unit 12 outputs an interlocking signal from the first terminal 51 in response to the occurrence of the first event. Also, the control unit 12 outputs an instruction signal from the second terminal 52 to the external device 2 in response to the occurrence of the first event. That is, the control unit 12 outputs an instruction signal by controlling the switch SW1 so as to close the report transfer contact in response to the occurrence of the first event.

Further, even when the interlocking signal is received (occurrence of the second event), the control unit 12 interlocks and outputs the instruction signal to the external device 2 so as to interlock with the interlocking signal. In other words, even if the first event has not occurred, the control unit 12 connects to its own device when the operation unit 11 of another alarm device 1 receives a push operation and receives an interlocking signal from another alarm device 1. An instruction signal is output to the external device 2 inside. That is, the control unit 12 outputs an instruction signal by controlling the switch SW1 to close the report transfer contact in response to the occurrence of the second event.

“Interlocking output” in the present disclosure means transmitting an instruction signal from the second terminal 52 to the external device 2 so as to interlock with the interlocking signal received from another alarm device 1 . However, the interlocking output can be switched between enabled and disabled by the switching unit 6, which will be described later.

The control unit 12 has a switching unit 6 as shown in FIG. In other words, the control section 12 functions as the switching section 6 . The switching unit 6 has a first setting (representative output setting) for executing an interlocking output when an interlocking signal is received from another alarm device 1 (occurrence of a second event), and an interlocking output even if an interlocking signal is received. Switch to the second setting (individual output setting) that is non-execution. In short, the first setting is for enabling the interlocked output, and the second setting is for disabling the interlocked output. The switching unit 6 switches between the first setting and the second setting according to, for example, the ON/OFF switching state of one or a plurality of DIP switches in the board (inside the housing 18). Each alarm device 1 can be individually set to either the first setting or the second setting depending on the installation environment or demand of the alarm system 100 .

Therefore, for example, if the alarm device 1A connected to the reporting station 21 is set to the first setting, the interlocking output is executed when the interlocking signal is received, and the reporting station 21 reports.

(2.2) Operation Inspection The control unit 12 is configured to perform an operation inspection when the inspection reception unit 15 receives an operation. In other words, the control unit 12 switches the operation mode to the inspection mode. The control unit 12 switches the main power supply from the AC power supply 3 to the emergency power supply 13 in the inspection mode. Then, in the inspection mode, the control unit 12 uses the emergency power supply 13 to output a notification sound on a trial basis. The inspector can confirm whether the alarm device 1 operates normally by confirming the notification sound.

In particular, the control unit 12 confirms whether the battery voltage of the emergency power supply 13 is normal or abnormal through the operation inspection as described above. Then, the control unit 12 presents the result to the inspector. Specifically, if the battery voltage of the emergency power supply 13 is normal, the control unit 12 turns on the battery confirmation lamp 162 in green, and if it is abnormal, turns on the battery confirmation lamp 162 in red.

By the way, the alarm system 100 of this embodiment is also configured to interlock with the operation inspection. When the inspection reception unit 15 of one alarm device 1 (one of the alarm devices 1) of the plurality of alarm devices 1 receives an operation, the one alarm device 1 performs its own operation inspection. Further, one alarm device 1 transmits an inspection signal to other alarm devices 1 among the plurality of alarm devices 1 via the first signal line L1. The other alarm device 1 performs its own operation check upon receiving the check signal. Therefore, if the inspector operates the inspection receiving unit 15 of one of the alarm devices 1, the operation inspection of the entire alarm system 100 can be started almost all at once.

(2.3) Wiring Reduction The first setting and second setting by the switching unit 6 will be described below with reference to FIGS. 3A, 3B, and 4 (comparative example).

The first setting is a setting for enabling the interlocked output as described above, and is a setting for outputting an instruction signal from the second terminal 52 to the connected external device 2 in response to the occurrence of the second event. Here, since the external device 2 connected to the alarm device 1A is the reporting station 21 (see FIG. 3A), the installer or the like must set the control unit 12 to follow the first setting by switching the DIP switch on and off. set to This is because the notification station 21 needs to notify the fire department even if any of the operation units 11 of the plurality of alarm devices 1 receives the push operation. As shown in FIG. 2, if the external device 2 is not connected to the alarm devices 1B and 1C other than the alarm device 1A, the first setting or the second setting may be used.

The second setting is a setting for disabling the interlocking output as described above, and is a setting that does not output an instruction signal to the connected external device 2 even if the second event occurs. In other words, the alarm device 1 causes the connected external device 2 to output an instruction signal only when the operation unit 11 of the alarm device 1 is pushed. If the external device 2 connected to the alarm device 1A is an external buzzer 22 (see FIG. 3B), the installer or the like sets the control unit 12 to follow the second setting by switching the DIP switch on and off. . This is because when the operation unit 11 of the alarm device 1 other than the alarm device 1A is pushed and the external buzzer 22 connected to the alarm device 1A executes the buzzer alarm and lamp lighting, which alarm device 1 This is because it becomes difficult for the surrounding people to determine whether the operation unit 11 of is operated. By switching on and off of the DIP switch so as to be the second setting, only when the operation unit 11 of the alarm device 1A is pushed, the external buzzer 22 connected to the self device emits a buzzer and a lamp. light up. If the alarm devices 1B and 1C other than the alarm device 1A are also connected to the external device 2, which is the external buzzer 22, the dip switch is turned on and off so that the controller 12 follows the second setting. May be set. However, when there is no need to notify the surrounding people of which operation unit 11 of the alarm device 1 has been pressed, that is, when it is desired to make all the external buzzers 22 sound at once, the installer or the like All may be set to follow the first setting.

As described above, the alarm device 1 has the function of executing the interlocking output of the instruction signal to the external device 2 so as to interlock with the interlocking signal even when the second event occurs. can be improved.

FIG. 4 shows an alarm system 100A as a comparative example for the alarm system 100 of this embodiment. Each alarm device 1 of the alarm system 100A of this comparative example is different from each alarm device 1 of the alarm system 100 of this embodiment, and does not have the function of interlocking output of the instruction signal when the second event occurs. and In the comparative example, even if only one of the plurality of alarm devices 1 is connected to the external device 2 in order to transfer the report to the external device 2 which is the reporting station 21, all of the plurality of alarm devices 1 , and a third signal line L3 indicated by a dashed line, it is necessary to connect them by a transition wiring method.

On the other hand, each alarm device 1 of the alarm system 100 of the present embodiment has a function of interlocking and outputting the instruction signal when the second event occurs. Wiring of the third signal line L3 may be unnecessary (reduction of wiring). Therefore, workability can be improved.

Further, even when it is desired to connect an external buzzer 22 to each alarm device 1 and operate a plurality of external buzzers 22 all at once, the alarm system 100A of the comparative example can connect all of the plurality of alarm devices 1 to the second terminal 52. It is necessary to connect using the crossover wiring method. However, since each alarm device 1 of the alarm system 100 of the present embodiment has a function of executing interlocking output of the instruction signal when the second event occurs, wiring is unnecessary as in the case of the reporting station 21. (saving wiring).

Further, in the present embodiment, since each alarm device 1 has the switching unit 6, it is possible to switch between the first setting and the second setting according to the type of the external device 2 connected to the alarm device 1. can.

(3) Modifications The embodiment described above is merely one of various embodiments of the present disclosure. The above-described embodiment can be modified in various ways according to design and the like, as long as the object of the present disclosure can be achieved. Further, functions similar to those of the alarm device 1 of the above-described embodiment may be embodied by a control method of the alarm device 1, a computer program, or a non-temporary recording medium recording the computer program. Specifically, a control method according to one aspect includes a first step, a second step, a third step, and a fourth step. In the first step, when the operation unit 11 receives a push operation or receives an interlocking signal from another alarm device 1, an alarm signal is output. In the second step, an alarm sound is output in response to the alarm signal. In the third step, an instruction signal is output to the external device 2 at least when the operation unit 11 receives the push operation. In the fourth step, even when the interlocking signal is received, the interlocking output of the instruction signal to the external device 2 is executed so as to interlock with the interlocking signal.

Modifications of the above embodiment are listed below. Modifications described below can be applied in combination as appropriate. Below, the above embodiment may be referred to as a "basic example".

The alarm device 1 in the present disclosure includes a computer system. A computer system is mainly composed of a processor and a memory as hardware. The function of the alarm device 1 (for example, the control unit 12) in the present disclosure is realized by the processor executing a program recorded in the memory of the computer system. The program may be recorded in advance in the memory of the computer system, may be provided through an electric communication line, or may be recorded in a non-temporary recording medium such as a computer system-readable memory card, optical disk, or hard disk drive. may be provided. A processor in a computer system consists of one or more electronic circuits, including semiconductor integrated circuits (ICs) or large scale integrated circuits (LSIs). The integrated circuit such as IC or LSI referred to here is called differently depending on the degree of integration, and includes integrated circuits called system LSI, VLSI (Very Large Scale Integration), or ULSI (Ultra Large Scale Integration). In addition, a field-programmable gate array (FPGA) that is programmed after the LSI is manufactured, or a logic device capable of reconfiguring the bonding relationship inside the LSI or reconfiguring the circuit partitions inside the LSI may also be adopted as the processor. can be done. A plurality of electronic circuits may be integrated into one chip, or may be distributed over a plurality of chips. A plurality of chips may be integrated in one device, or may be distributed in a plurality of devices. A computer system, as used herein, includes a microcontroller having one or more processors and one or more memories. Accordingly, the microcontroller also consists of one or more electronic circuits including semiconductor integrated circuits or large scale integrated circuits.

Moreover, it is not an essential configuration for each alarm device 1 that a plurality of functions of the alarm device 1 are integrated in one housing. The constituent elements of each alarm device 1 may be distributed over a plurality of housings. Furthermore, at least part of the functions of the alarm device 1, for example, part of the functions of the alarm device 1, may be realized by the cloud (cloud computing) or the like. Conversely, as in the basic example, multiple functions of each alarm device 1 may be integrated into one housing.

In the basic example, the alarm device 1 includes an emergency power supply 13, but the emergency power supply 13 is not an essential component of the alarm device 1 and may be omitted as appropriate. The alarm device 1 may use a private power generator or the like as a main power supply instead of the AC power supply 3, or may use both the AC power supply 3 and the private power generator as main power supplies.

In the basic example, the control unit of the alarm device 1 has the switching unit 6, but the function (valid, invalid) of the switching unit 6 is not an essential component in the alarm device 1 of this embodiment, but can be changed as appropriate. may be omitted.
