(1) Overview The following embodiments are merely one of various embodiments of the present invention. The following embodiments can be variously modified according to the design and the like as long as the object of the present invention can be achieved. Further, each figure described in the following embodiments is a schematic view, and the ratio of the size and the thickness of each component in each figure does not necessarily reflect the actual dimensional ratio. do not have.

As shown in FIG. 3, the alarm device 1 of the present embodiment is installed in a structure C1 (a building material such as a ceiling or a wall). As shown in FIG. 2, the alarm device 1 includes a device detection unit 6, a control unit 10, and a notification unit 8. The device detection unit 6 detects the first information corresponding to the internal event related to the alarm device 1 itself. The control unit 10 receives the first information and determines whether or not an internal event has occurred. Further, the control unit 10 receives the second information regarding the external event for which the alarm sound is issued, and determines whether or not the external event has occurred. The notification unit 8 notifies the occurrence of an internal event and the occurrence of an external event.

Here, the "internal event" includes, for example, at least the replacement time of the alarm device 1. In addition to the replacement time, the internal event may include a failure in the alarm 1 and a dead battery.

Moreover, it is assumed that the "external event" is a fire as an example. Therefore, the alarm device 1 is, for example, a fire alarm device that outputs a sound such as an alarm sound when a fire occurs. However, the external event is not limited to a fire as long as it is the subject of the alarm sound, and may be a gas leak, a tsunami, an earthquake, an intrusion of a suspicious person, or the like.

As shown in FIG. 2, the alarm device 1 of the present embodiment further includes a photoelectric sensor (fire detection unit 2) for detecting smoke inside the alarm device 1, but the fire detection unit 2 detects heat. It may be a constant temperature type sensor. Further, the fire detection unit 2 may be separate from the alarm device 1. The control unit 10 of the alarm device 1 may receive the second information regarding the fire by communicating with another alarm device (fire alarm device) provided with the fire detection unit 2.

The alarm 1 is installed on one surface (ceiling surface or wall surface) of the structure C1 such as a living room, a bedroom, a staircase, and a corridor in a house. The house may be a detached house or an apartment house (apartment). Further, the alarm 1 may be installed not only in a house but also in a non-house structure C1 (ceiling surface, wall surface, etc.). Examples of non-residential buildings include office buildings, theaters, movie theaters, public halls, amusement parks, complexes, restaurants, department stores, schools, hotels, inns, hospitals, geriatric homes, kindergartens, libraries, museums, museums, underground streets, stations. , Airports, etc.

The control unit 10 of the present embodiment causes the notification unit 8 to notify the fire prior to the notification of the replacement time of the alarm device 1. According to this configuration, the fire notification is performed before the replacement time notification. Therefore, it is possible to suppress the fact that the user cannot be notified of the outbreak of the fire because the notification of the replacement time with low urgency is being executed even though the fire that is the target of the alarm sound has occurred. Therefore, it is possible to improve the reliability of notification.

(2) Details (2.1) Overall configuration The overall configuration of the alarm device 1 of the present embodiment will be described in detail below. Here, the alarm 1 is, for example, a battery-powered fire alarm. However, the alarm 1 is a fire alarm that is electrically connected to an external power source (for example, a commercial power system) and is driven by converting AC power (for example, an effective value of 100 V) supplied from the external power source into a direct current. There may be.

In the following, as shown in FIG. 3, it is assumed that the alarm 1 is installed on the ceiling surface (one surface of the structure C1) in the house of the resident 100 as an example. Thereby, the up / down / left / right directions of the alarm device 1 will be described by defining them using the up / down / left / right arrows shown in FIG. These arrows are provided for the purpose of assisting explanation only and are not accompanied by substance. Further, these directions are not intended to limit the direction in which the alarm device 1 is used.

As shown in FIG. 2, the alarm device 1 includes, for example, a second output unit in addition to the control unit 10, the device detection unit 6, the notification unit 8 (first output unit 11 and the operation light 15), and the fire detection unit 2. A 12, battery 13, an operation unit 3, a housing 4, and a translucent unit 5 (see FIG. 1) are further provided. Further, the alarm device 1 further includes a storage unit 7. As an example, it is assumed that the alarm device 1 is a stand-alone fire alarm system and does not have a communication function for communicating with other fire alarm systems.

(2.2) Housing The housing 4 includes a control unit 10, a device detection unit 6, a first output unit 11, a second output unit 12, a battery 13, a fire detection unit 2, an operation light 15, a storage unit 7, and a storage unit 7. , A circuit board (not shown) on which a control unit 10 and circuit components constituting various circuits are mounted is housed therein. Although not shown, the various circuits referred to here are, for example, an acoustic circuit, a first lighting circuit, a second lighting circuit, a power supply circuit, and the like, which will be described later.

The housing 4 is made of synthetic resin, for example, flame-retardant ABS resin. The housing 4 is formed in a flat cylindrical shape as a whole. The housing 4 has a mounting portion on its upper surface, and is mounted on one surface (installation surface) of the structure C1 by the mounting portion.

As shown in FIG. 1, the housing 4 has a hole 401 in its peripheral wall 400 capable of introducing smoke into a labyrinth provided in the housing 4. The housing 4 has a partition wall that divides the internal space into two upper and lower parts. The labyrinth and the fire detection unit 2 are in the upper first space, and the control unit 10, the first output unit 11, the second output unit 12, the operation light 15, the circuit board, etc. are in the lower second space. ..

Further, the housing 4 has a long slit-shaped window hole 403 in one direction (left-right direction in FIG. 1) on the lower wall (cover) 402 thereof. The window hole 403 is arranged so as to face the first output unit 11 housed in the housing 4. The window hole 403 derives the sound output from the first output unit 11 to the outside of the housing 4.

Further, the housing 4 supports the translucent portion 5 on the lower wall 402 so that the lower surface of the translucent portion 5 is exposed to the outside of the housing 4. The translucent portion 5 is a disk-shaped member having translucency. The translucent portion 5 is formed of a material such as acrylic resin or glass. The translucent unit 5 is arranged so as to face the second output unit 12 housed in the housing 4. The translucent unit 5 leads the light emitted from the second output unit 12 to the outside of the housing 4. The light of the second output unit 12 may be referred to as "illumination light", but the light of the second output unit 12 has a weaker brightness than the illumination light output by a general lighting fixture, and is an evacuation route. It is a light that illuminates. The translucent unit 5 has a lens unit whose outer surface is formed in a convex shape in order to distribute the light from the second output unit 12 toward the peripheral region R1 such as the floor surface. May be good. Further, a light guide member may be provided between the translucent unit 5 and the second output unit 12 to efficiently guide the light from the second output unit 12 to the translucent unit 5.

Further, the housing 4 supports the operation unit 3 on the lower wall 402 thereof so that the lower surface of the operation unit 3 is exposed to the outside of the housing 4. The operation unit 3 receives an operation input from the outside. The operation unit 3 can be pushed upward by a pushing operation with a user's finger or the like. The operation unit 3 is a disc-shaped member having translucency. The operation unit 3 is arranged so as to face the operation light 15 housed in the housing 4. Further, the operation unit 3 is configured to push a push button switch (not shown) housed in the housing 4 by a push operation.

In the present embodiment, as an example, when the lower surface of the lower wall 402 is viewed from below, the window hole 403 and the operation unit 3 sandwich the center of the lower surface of the lower wall 402 between the window hole 403 and the operation unit 3. They are lined up in one direction (left and right in FIG. 1). Further, the translucent portion 5 is arranged in front of the center of the lower surface of the lower wall 402 when the lower surface of the lower wall 402 is viewed from below.

(2.3) Notification unit The notification unit 8 has a replacement time of the alarm device 1 (hereinafter, simply referred to as “replacement time”), which is an internal event, and a failure in the alarm device 1 (hereinafter, simply referred to as “failure”). ), And the occurrence of a dead battery (a state in which the remaining capacity of the battery 13 is low) is notified. The battery 13 is, for example, a lithium battery. Further, the notification unit 8 notifies the occurrence of a fire of an external event. Here, both the first output unit 11 and the operation light 15 correspond to the notification unit 8, but only one of them may correspond to the notification unit 8.

The first output unit 11 has a function of notifying the occurrence of an internal event and a function of notifying the occurrence of a fire. The first output unit 11 outputs sound (sound wave). When the control unit 10 determines that a fire has occurred, the first output unit 11 outputs an alarm sound so as to notify the occurrence of a fire.

The first output unit 11 is composed of a speaker that converts an electric signal into sound. The speaker has a diaphragm and emits an alarm sound by mechanically vibrating the diaphragm according to an electric signal. The speaker is formed in a circular shape when viewed from the front, and has a disk shape. The first output unit 11 outputs an alarm sound (for example, a “beep” sound) under the control of the control unit 10. It is preferable that the first output unit 11 outputs the alarm sound by changing the loudness (sound pressure level) of the alarm sound. The alarm sound may include, for example, a sweep sound swept from a low tone to a high tone. The audible alarm may include a voice message such as "Fire. Fire." Here, it is assumed that the alarm sound is composed of a sweep sound and a voice message continuous with the sweep sound.

For example, circuit components constituting an acoustic circuit are mounted on the above circuit board. The acoustic circuit includes a low-pass filter, an amplifier, and the like. When the acoustic circuit receives a PWM (Pulse Width Modulation) signal corresponding to the alarm sound generated by the control unit 10 when a fire occurs, it converts it into a sinusoidal audio signal with a low-pass filter, amplifies it with an amplifier, and makes an alarm sound. Is output from the first output unit 11.

When the control unit 10 determines that any of the internal events has occurred, the first output unit 11 outputs a sound for notifying the occurrence of the internal event. Hereinafter, this sound may be referred to as a "notification sound" in order to distinguish it from an alarm sound at the time of a fire.

An example of a notification sound regarding the replacement time includes a voice message such as "Pip, it is time to replace the alarm." In addition, an example of a notification sound related to a failure includes a voice message such as "A failure has occurred in XX." In addition, an example of a notification sound regarding a dead battery includes a voice message such as "Pip, replace the battery."

The notification sound is output at a volume of about 60 to 70% of the volume of the alarm sound. The notification sound is periodically and repeatedly output, for example, at an interval of 1 hour until the corresponding internal event is resolved. The first output unit 11 continuously outputs a message such as "Pip, replace the battery" every hour two to three times, and then every 40 seconds until one hour elapses. Outputs a beeping sound.

The first output unit 11 outputs an alarm sound and a notification sound on a trial basis even during an operation check. The operation check can be performed by pushing the operation unit 3 or pulling the drawstring (not shown) derived from the housing 4.

In the present embodiment, when the operation unit 3 receives an operation input from the outside during an alarm (alarm sound is being issued), the first output unit 11 stops the output of the alarm sound.

The operation light 15 has a function of notifying the occurrence of an internal event and a function of notifying the occurrence of a fire. The operating light 15 has a red LED (Light Emitting Diode) 15A mounted on the circuit board as a light source. The operation light 15 is normally turned off (during fire monitoring), and starts blinking (or lit) when the control unit 10 determines that a fire has occurred. Hereinafter, the blinking that notifies the occurrence of a fire may be referred to as "operation blinking". The operation blinking stops under the control of the control unit 10 when the alarm sound is stopped.

On the circuit board, circuit components constituting a first lighting circuit for blinking the LED 15A of the operating light 15 are mounted. The first lighting circuit blinks the LED 15A using the DC power discharged from the battery 13 under the control of the control unit 10. When the alarm 1 is electrically connected to a commercial power system, the first lighting circuit converts the AC power supplied from the power system into a direct current and causes the LED 15A to blink.

The light emitted from the operating lamp 15 is led out to the outside of the housing 4 via the translucent operating unit 3. The resident 100 can know that the alarm device 1 is operating (fire is being detected) by visually recognizing the red operation blinking of the operation unit 3.

When the control unit 10 determines that any of the internal events has occurred, the operation light 15 blinks to notify the occurrence of the internal event. Hereinafter, this blinking may be referred to as "notification blinking". The operation light 15 blinks the notification regardless of whether the replacement time, the failure, or the battery runs out. However, if the operation unit 3 is operated while the notification is blinking, the first output unit 11 outputs a notification sound corresponding to an internal event that is actually occurring.

The operation light 15 blinks even during the operation check. The operation check of the operation light 15 can be performed by pushing the operation unit 3 or pulling the drawstring, as in the case of the first output unit 11.

(2.4) Second Output Unit The second output unit 12 outputs illumination light that illuminates the surrounding area R1 in response to information regarding a fire under the control of the control unit 10. The second output unit 12 has one or a plurality of white lighting LEDs 12A mounted on the above circuit board as a light source (see FIG. 2). The second output unit 12 is normally turned off, and starts lighting (output of illumination light) when the control unit 10 determines that a fire has occurred. Therefore, for example, even if a fire breaks out in the middle of the night when the resident 100 is sleeping, the resident 100 does not need to turn on the wall switch to turn on the lighting fixture, but the illumination light of the second output unit 12 is used. You can immediately see the evacuation route and evacuate using.

The LED 12A is configured as a package-type LED in which at least one LED chip is mounted in the center of the mounting surface of a flat plate-shaped mounting board. The LED chip is preferably, for example, a blue light emitting diode that emits blue light from a light emitting surface. Further, the mounting surface of the substrate including the LED chip is covered with a sealing resin mixed with a fluorescent substance that converts the wavelength of blue light emitted from the LED chip. The LED 12A is configured to radiate white illumination light from the light emitting surface by applying a DC voltage between the anode electrode and the cathode electrode. The color of the illumination light is not limited to white, and may be another light color. However, it is desirable that it does not overlap with the light color of the operating light 15.

On the circuit board described above, circuit components constituting a second lighting circuit for lighting the LED 12A of the second output unit 12 are mounted. The second lighting circuit uses the DC power discharged from the battery 13 to light the LED 12A under the control of the control unit 10. When the alarm 1 is electrically connected to a commercial power system, the second lighting circuit converts the AC power supplied from the power system into a direct current to light the LED 12A.

The light (illuminating light) emitted from the second output unit 12 is led out to the outside of the housing 4 via the translucent unit 5, and the surrounding area R1 (here, the floor surface of the bedroom, the bed, etc.) Be illuminated. The second output unit 12 lights up on a trial basis even during an operation check. The operation check of the second output unit 12 can be performed by pushing the operation unit 3 or pulling the drawstring, as in the case of the first output unit 11.

(2.5) Device detection unit The device detection unit 6 detects the first information corresponding to an internal event related to the alarm device 1 itself. As described above, the internal event includes at least the replacement time of the alarm device 1, and other events including the failure in the alarm device 1 and the battery exhaustion other than the replacement time. Therefore, the first information includes the usage time corresponding to the replacement time, the information of the electric or thermal physical quantity corresponding to the failure, the remaining capacity of the battery 13 corresponding to the dead battery, and the like. As shown in FIG. 2, the device detection unit 6 has a first detection unit 61, a second detection unit 62, and a third detection unit 63. The first to third detection units 61 to 63 are electrically connected to the control unit 10.

The first detection unit 61 has a timer that measures the usage time corresponding to the replacement time. Here, the usage time is, for example, 10 years. The first detection unit 61 measures the usage time and outputs the usage time information to the control unit 10 as the first information. The control unit 10 determines whether or not a replacement time has occurred based on the information on the usage time.

The second detection unit 62 detects, for example, an electrical physical quantity corresponding to a failure. The second detection unit 62 may detect a thermal physical quantity in addition to the electrical physical quantity. The "failure" referred to here corresponds to, for example, a failure of the fire detection unit 2, a failure of the acoustic circuit, a failure of the first and second lighting circuits, a disconnection of the electric wire in the device, and the like. The disconnection of the electric wire is, for example, the disconnection of the electric wire from the acoustic circuit to the first output unit 11. The second detection unit 62 detects an electric physical quantity (current or voltage) in a predetermined electric circuit, and outputs an electric signal including the physical quantity to the control unit 10 as first information. The control unit 10 determines whether or not a failure has occurred based on the physical quantity information.

The third detection unit 63 detects the remaining capacity of the battery 13. The third detection unit 63 detects, for example, the battery voltage of the battery 13 corresponding to the remaining capacity, and outputs an electric signal including the battery voltage to the control unit 10 as the first information. The control unit 10 determines whether or not the battery has run out based on the information on the battery voltage.

(2.6) Fire detection unit The fire detection unit 2 detects the second information regarding the fire (external event) for which the alarm sound is issued. Here, the fire detection unit 2 is, for example, a photoelectric sensor that detects smoke. Therefore, the second information includes, for example, information about smoke. As shown in FIG. 2, the fire detection unit 2 includes, for example, a light emitting unit 21 such as an LED and a light receiving unit 22 such as a photodiode. The light emitting unit 21 and the light receiving unit 22 are arranged in the labyrinth of the housing 4 so that the light receiving surface of the light receiving unit 22 is off the optical axis of the irradiation light of the light emitting unit 21. In the event of a fire, smoke can be introduced into the labyrinth through holes 401 in the peripheral wall 400 of the housing 4.

When there is no smoke in the labyrinth of the housing 4, the irradiation light of the light emitting unit 21 hardly reaches the light receiving surface of the light receiving unit 22. On the other hand, when smoke is present in the labyrinth of the housing 4, the irradiation light of the light emitting unit 21 is scattered by the smoke, and a part of the scattered light reaches the light receiving surface of the light receiving unit 22. That is, the fire detection unit 2 receives the irradiation light of the light emitting unit 21 scattered by the smoke by the light receiving unit 22.

The fire detection unit 2 is electrically connected to the control unit 10. The fire detection unit 2 transmits an electric signal (detection signal) indicating a voltage level corresponding to the amount of light received by the light receiving unit 22 to the control unit 10. The control unit 10 converts the amount of light of the detection signal received from the fire detection unit 2 into smoke concentration (event level) to determine a fire. The fire detection unit 2 may convert the amount of light received by the light receiving unit 22 into smoke concentration and then transmit a detection signal indicating a voltage level according to the smoke concentration to the control unit 10. Alternatively, the fire detection unit 2 may determine the occurrence of a fire (smoke) from the amount of light received by the light receiving unit 22, and may transmit a detection signal including information that a fire has occurred to the control unit 10.

(2.7) Control unit and storage unit The control unit 10 is composed of, for example, a CPU (Central Processing Unit) and a microcomputer having a memory as a main configuration. In other words, the control unit 10 is realized by a computer having a CPU and a memory, and the computer functions as the control unit 10 by executing a program stored in the memory by the CPU. Although the program is pre-recorded in the memory here, the program may be provided by being recorded in a telecommunication line such as the Internet or recorded in a recording medium such as a memory card.

The control unit 10 includes a first output unit 11, an acoustic circuit, a second output unit 12, an operation light 15, a first lighting circuit, a second lighting circuit, a fire detection unit 2, a device detection unit 6, a storage unit 7, and the like. Control. Further, the control unit 10 controls a power supply circuit that generates operating power of various circuits from the DC power of the battery 13. The storage unit 7 is a memory in which data can be rewritten, and is preferably a non-volatile memory. The storage unit 7 may be a memory owned by the control unit 10 itself.

The control unit 10 is configured to receive information about a fire (second information) from the fire detection unit 2 and determine whether or not a fire has occurred. Hereinafter, the determination of the presence or absence of a fire will be described in detail.

The control unit 10 monitors the detection signal (information) received from the fire detection unit 2 and determines whether or not the event level included in the detection signal exceeds the threshold value. As mentioned above, the event level is, for example, the smoke concentration after conversion. However, the event level may be the amount of light.

The control unit 10 stores the threshold value in the storage unit 7 or its own memory. For example, the control unit 10 may periodically determine whether or not the smoke concentration exceeds the threshold value at predetermined time intervals, and if the smoke concentration exceeds the threshold value even once, it may be determined that a fire has occurred. The predetermined time interval is, for example, a 5 second interval. Alternatively, the control unit 10 may count the number of times the smoke concentration continuously exceeds the threshold value, and may determine that a fire has occurred when the number of times reaches a predetermined number of times. Of course, the control unit 10 may directly determine that a fire has occurred if it receives a detection signal including information that a fire has occurred from the fire detection unit 2.

When the control unit 10 determines that a fire has occurred based on the smoke concentration, the control unit 10 starts outputting an alarm sound from the first output unit 11. Specifically, the control unit 10 generates a PWM signal corresponding to a sweep sound whose frequency changes linearly with the passage of time, and outputs the PWM signal to the acoustic circuit. The PWM signal is converted into an audio signal by an acoustic circuit, and a sweep sound (alarm sound) is output from the first output unit 11. Further, the control unit 10 generates a PWM signal corresponding to the voice message based on the message data stored in the storage unit 7 or its own memory, and outputs the PWM signal to the acoustic circuit. The PWM signal is converted into a voice signal by an acoustic circuit, and a voice message (alarm sound) is output from the first output unit 11.

Further, when the control unit 10 determines that a fire has occurred, the control signal for blinking the operation light 15 is sent to the first lighting circuit, and the control signal for lighting the second output unit 12 is sent to the second lighting circuit. Send. When the first lighting circuit receives the control signal from the control unit 10, the operation light 15 starts blinking. When the second lighting circuit receives the control signal from the control unit 10, the second lighting circuit lights the second output unit 12 with a constant brightness.

The control unit 10 determines the smoke concentration even during an alarm (alarm sound is being issued). If the smoke concentration becomes equal to or less than the reference value during the alarm, the control unit 10 stops the generation of the PWM signal, stops the output of the alarm sound by the first output unit 11, and also outputs the stop signal to the first lighting circuit and the first lighting circuit. The light output from the second output unit 12 and the operation light 15 is also stopped by transmitting to the second lighting circuit, respectively. That is, when the control unit 10 determines that the fire (smoke) has disappeared, it automatically stops the output of the alarm sound, the output of the illumination light, and the blinking of the operation light 15.

Further, the control unit 10 stops the output of the alarm sound when the push button switch in the housing 4 is turned on by the push operation to the operation unit 3 during the alarm. If the resident 100 determines that the alarm of the alarm device 1 is a false alarm, the alarm sound can be stopped by pressing the operation unit 3. It is also possible to stop the alarm sound by pulling the drawstring.

On the other hand, the control unit 10 executes a predetermined operation test for operation check when the push button switch in the housing 4 is turned on by a push operation to the operation unit 3 during non-alarm. The operation test includes a sound output test of the first output unit 11, an optical output test of the second output unit 12, a blinking test of the operation light 15, and the like. The operation test can also be performed by pulling the drawstring.

Here, the control unit 10 is configured to receive information (first information) regarding an internal event from the device detection unit 6 and determine whether or not an internal event has occurred. Hereinafter, the determination of the presence or absence of the occurrence of an internal event will be described in detail.

The control unit 10 monitors the usage time received from the first detection unit 61. The usage time is, for example, the time when the power is turned on and the alarm device 1 is in the operating state. The control unit 10 accumulates and stores the usage time received from the first detection unit 61 in the storage unit 7 or its own memory. When the cumulative usage time reaches 10 years, the control unit 10 determines that the replacement time has occurred, and notifies the operation light 15 which is the notification unit 8 to notify. That is, the operation light 15 starts blinking the notification. The replacement time is less urgent than the dead battery or failure, and the replacement of the alarm 1 is convenient for the resident 100. Therefore, the control unit 10 does not output a voice message notifying the replacement time immediately after the determination from the first output unit 11, but outputs only when the operation unit 3 during the notification blinking is pushed and operated by the resident 100.

The control unit 10 monitors information on electrical physical quantities received from the second detection unit 62. For example, if the current value of the current flowing from the acoustic circuit to the first output unit 11 is an abnormal value (zero or a value close to zero, etc.), the control unit 10 determines that the disconnection has occurred. Further, if the voltage value of a predetermined electric circuit in various circuits is an abnormal value, the control unit 10 determines that a failure has occurred in the circuit. The control unit 10 may monitor information such as temperature received from the second detection unit 62, and if there is abnormal heat generation in various circuits, it may be determined that a failure has occurred. When the control unit 10 determines that a failure has occurred, the control unit 10 notifies the first output unit 11 and the operation light 15 which are the notification units 8 to notify. That is, a voice message notifying the failure is output from the first output unit 11, and the operation light 15 starts blinking. If there is a disconnection between the acoustic circuit and the first output unit 11, the notification by the first output unit 11 is not possible, so only the notification by the operating light 15 is performed.

The control unit 10 monitors the battery voltage information of the battery 13 received from the third detection unit 63. The control unit 10 stores in advance characteristic data in which the battery voltage and capacity of the battery 13 are associated with each other in the storage unit 7 or its own memory, and the remaining capacity corresponding to the received battery voltage is less than 10% of the capacity. If so, it is determined that the battery has run out. When the control unit 10 determines that the battery has run out, the control unit 10 notifies the first output unit 11 and the operation light 15 which are the notification units 8. That is, a voice message notifying that the battery is dead is output from the first output unit 11, and the operation light 15 starts blinking.

The control unit 10 determines whether or not an internal event has occurred at a predetermined cycle. As an example, the determination of an internal event is performed once a day at midnight.

Regarding the voice message notifying the occurrence of an internal event, the control unit 10 generates a PWM signal based on the message data stored in the storage unit 7 or its own memory, and responds via the acoustic circuit. The voice message is output from the first output unit 11.

Here, for example, when a fire breaks out in a house at midnight, the resident 100 sleeping in the bedroom of the house gets up from the bed in a state close to dark after hearing the alarm sound, and goes from the bed to the corridor. It may be difficult to instantly grasp the route and direction to the connecting door. In addition, the resident 100 may, for example, go to the wall switch by groping in the dark and try to turn on the lighting of the bedroom, and the action until the wall switch is turned on may lead to a delay in evacuation. Further, if the resident 100 is, for example, a hearing-impaired person, there is a possibility that the occurrence of a fire may not be noticed only by the alarm sound (sound). On the other hand, since the alarm device 1 outputs not only the alarm sound but also the illumination light of the second output unit 12, the resident 100 momentarily sets the route (evacuation route) from the bed to the door leading to the corridor. It is more likely that you will not have to spend time trying to turn on the lights in your bedroom. Further, even if the resident 100 is a hearing-impaired person, there is a high possibility that the occurrence of a fire will be noticed by the illumination light of the second output unit 12. In short, since the alarm device 1 outputs not only the alarm sound but also the illumination light, the evacuation time can be shortened.

(2.8) Priority of events By the way, any two or more of fire, replacement time, failure and dead battery may occur at substantially the same timing. For example, a replacement period may occur during an alarm for a fire. Alternatively, a fire may occur while notifying the occurrence of a dead battery. In addition, another event of the internal event may occur while notifying the occurrence of any one of the internal events.

Therefore, the control unit 10 sets priorities in the order of notifying these events, and causes the notification unit 8 to preferentially notify the high-priority events. The control unit 10 causes the notification unit 8 to give priority to the notification of the replacement time before the notification of the fire. Further, the control unit 10 causes the notification unit 8 to give the highest priority to the notification of the fire before the notification of any internal event. Further, the control unit 10 causes the notification unit 8 to notify the failure and the battery exhaustion other than the notification of the replacement time in the internal event before the notification of the replacement time.

That is, when the control unit 10 determines that a plurality of events such as a fire, a replacement time, a failure, and a dead battery have occurred, the control unit 10 sequentially responds to the notification in descending order of priority. The priority (priority rank) is, for example, from the highest to the highest, fire, failure, dead battery, and replacement time. The storage unit 7 stores in advance priority information such as rank A for fire, rank B for failure, rank C for dead battery, and rank D for replacement time. Rank A has the highest priority and rank D has the lowest priority.

When an event with a priority rank higher than the priority rank of the event currently being notified or to be notified occurs later, the control unit 10 interrupts the notification of the event with the lower priority rank and notifies the event with the higher priority rank. Interrupt and execute. Further, when an event having a priority rank lower than the priority rank of the event currently being notified or to be notified is generated later, the control unit 10 continues or starts the notification of the event having the higher priority rank as it is, and ranks the priority rank. Notify a low event immediately and put it in a waiting state.

In particular, when the control unit 10 determines that an internal event has occurred, the control unit 10 stores the generation flag in the storage unit 7. The storage unit 7 has, for example, a storage area for three generation flags corresponding to a replacement time, a failure, and a dead battery. When the control unit 10 determines that the exchange time has occurred, the control unit 10 writes the generation flag "1" in "0" of the storage area corresponding to the exchange time.

When the fire notification response is completed, the control unit 10 starts the notification response of the internal event if the occurrence flag "1" is present in the storage unit 7. If two or more occurrence flags "1" are present in the storage unit 7, notification of an event having a high priority rank is started first. As for the situation of "the fire notification response is completed", when the alarm is erroneous and the resident 100 presses the operation unit 3 to stop the alarm sound, the smoke concentration becomes less than the reference value and the alarm sound is automatically emitted. For example, when the alarm is stopped. The occurrence flag in the storage unit 7 is erased (rewritten from "1" to "0") when the notification response of the corresponding internal event is completed. The situation in which the notification response of the internal event is completed is when the battery 13 is replaced, when the disconnection is resolved, and the like.

(2.9) Explanation of Operation Hereinafter, as an example, the operation of the alarm device 1 when "fire", "out of battery", and "replacement time" occur at substantially the same timing will be described. Since there is a high possibility that "out of battery" will be confirmed once a day at midnight, the notification should be executed about 6 hours after it is determined that the occurrence has occurred and the occurrence flag is stored. However, for convenience of explanation, the delay will not be taken into consideration.

First, a case where “fire”, “battery exhaustion”, and “replacement time” occur in this order will be described with reference to the flowchart of FIG.

When the control unit 10 determines that a "fire" has occurred (step S1), the "fire" alarm is started (step S2). It is assumed that the control unit 10 determines that "battery exhaustion" may occur during the alarm sound (step S3). In a state where the remaining capacity of the battery 13 is originally relatively small, it is quite possible that the power consumption is rapidly increased by the alarm sound and the remaining capacity becomes less than 10% during the alarm sound. However, since the control unit 10 is alarming the occurrence of the highest rank A "fire", the storage unit 7 does not execute the notification of the occurrence of the "out of battery" and stores only the occurrence flag of the "out of battery". (Step S4), and the notification is put into a waiting state.

Subsequently, it is assumed that the control unit 10 determines that the "replacement time" may occur while the alarm sound is being issued (step S5). However, since the control unit 10 is alarming the occurrence of the highest rank A "fire", it does not execute the notification of the occurrence of the "replacement time" and stores only the occurrence flag of the "replacement time". (Step S6), and the notification is put into a waiting state.

If the alarm is found to be a false alarm and the resident 100 presses and operates the operation unit 3 (step S7), the control unit 10 stops issuing the alarm sound (step S8). Here, since the storage unit 7 has two generation flags when the fire notification response is completed, the control unit 10 starts these notifications. However, since the rank C “battery dead” has a higher priority than the rank D “replacement time”, the control unit 10 starts notifying the “battery dead” (step S9).

When the resident 100 notices the "out of battery" and replaces the battery 13 (step S10), the control unit 10 ends the notification of "out of battery" and erases the "out of battery" generation flag (step S11). .. Since the storage unit 7 has a "replacement time" generation flag when the battery exhaustion notification response is completed, the control unit 10 starts this notification (step S12). However, since the "replacement time" is less urgent, only the notification blinking of the operation light 15 is started, and the voice message is output only when the operation unit 3 blinking in red is operated. Regarding the notification of "out of battery", only the notification blinking of the operation light 15 may be started, and the voice message may be output only when the operation unit 3 is operated.

Next, a case where “battery exhaustion”, “replacement time”, and “fire” occur in this order will be described with reference to the flowchart of FIG.

When the control unit 10 determines that the "battery dead" has occurred (step S21), the control unit 10 starts notifying the "battery dead" (step S22), and stores the "battery dead" occurrence flag in the storage unit 7 (step S21). Step S23). It is assumed that the control unit 10 determines that the “replacement time” may occur during the notification of the “battery dead” (step S24). However, since the control unit 10 is notifying the occurrence of the rank C “battery dead”, the control unit 10 does not execute the notification of the occurrence of the rank D “replacement time” and stores only the “replacement time” generation flag. (Step S25), the notification is put into a waiting state.

Subsequently, it is assumed that the control unit 10 further determines that a "fire" has occurred while the "battery dead" is being notified (step S26). The control unit 10 temporarily stops the notification of the "dead battery" of rank C, interrupts the alarm of "fire" of rank A and starts (step S27), and puts the notification of "out of battery" in the waiting state. ..

If the alarm is found to be a false alarm and the resident 100 presses and operates the operation unit 3 (step S28), the control unit 10 stops issuing the alarm sound (step S29). Here, since the storage unit 7 has two generation flags when the fire notification response is completed, the control unit 10 starts these notifications. However, since the rank C “battery dead” has a higher priority than the rank D “replacement time”, the control unit 10 restarts the notification of the “battery dead” (step S30).

When the resident 100 notices the "out of battery" and replaces the battery 13 (step S31), the control unit 10 ends the notification of the "out of battery" and erases the "out of battery" generation flag (step S32). .. Since the storage unit 7 has a "replacement time" generation flag when the battery exhaustion notification response is completed, the control unit 10 starts this notification (step S33).

As described above, in the present embodiment, the notification of the fire is performed before the notification of the replacement time. Therefore, it is possible to suppress the fact that the resident 100 cannot be notified of the outbreak of the fire because the notification of the replacement time is being executed even though the fire that is the target of the alarm sound has occurred. Therefore, it is possible to improve the reliability of notification. In particular, fire notification is the highest priority and is performed before any internal event notification, so by setting the fire notification priority rank to the highest, including internal events, the reliability of fire notification will be improved. be able to.

In addition, notification of failure and battery exhaustion other than notification of replacement time is performed prior to notification of replacement time. Even for internal events, by setting the priority rank of notification of the exchange time, which is relatively less urgent, to the lowest, it is possible to improve the reliability of notification of other events.

Further, in the present embodiment, when it is determined that an internal event has occurred, the occurrence flag is stored. Therefore, even if a fire occurs and the notification of the occurrence of the fire is interrupted immediately before or during the notification of the occurrence of the internal event, the notification of the internal event should be resumed after the fire notification response is completed. Can be done. Alternatively, even if an internal event occurs while the occurrence of a fire is already being notified, the internal event can be notified after the fire notification response is completed.

(3) Modification examples The following are some modifications. Hereinafter, the above-described embodiment will be referred to as a “basic example”. Each of the modified examples described below can be applied in combination with the above-mentioned basic example and other modified examples as appropriate.

(3.1) Modification 1
If the occurrence flag is present in the storage unit 7 when the fire notification response is completed, the control unit 10 of the basic example starts the notification response of the corresponding internal event. That is, if the control unit 10 of the basic example determines that an internal event has occurred even once, the control unit 10 sequentially executes the notification without abandoning the notification. However, even if the occurrence flag is present, it is not essential to sequentially execute the notification of the internal event.

The control unit 10 of this modification forcibly erases the occurrence flag without starting the notification response of the internal event even if the occurrence flag exists in the storage unit 7 when the fire notification response is completed. It is configured to do. The occurrence of a fire can be a greater mental burden on the Resident 100 than any internal event. For example, if the alarm is found to be a false alarm and the resident 100 is relieved to stop the alarm sound, and then the notification of an internal event that is less urgent than the fire is executed in quick succession, the resident 100 feels uncomfortable or anxious. It may give a feeling. Therefore, it is possible to suppress the discomfort and anxiety given to the resident 100 by forcibly deleting the occurrence flag without starting the notification response of the internal event only when the notification response of the fire is completed. Assuming that the control unit 10 determines the internal event in a cycle of, for example, every hour, the internal event is not notified until the time of the next regular determination process.

If the occurrence flag of another internal event is present when the notification response of the internal event is completed, the control unit 10 causes the occurrence of the other internal event without clearing the occurrence flag. Start notification.

By the way, the configuration in which the generation flag is stored in the storage unit 7 is not an essential component for the alarm device 1. For example, the control unit 10 does not have to store the generation flag in the storage unit 7 even if it determines that the “replacement time” having the lowest priority rank has occurred.

(3.2) Modification 2
The alarm device 1 of the basic example was a stand-alone fire alarm system. That is, the alarm device 1 of the basic example does not have a communication function for communicating with other fire alarm devices. However, the alarm device 1 may be an interlocking fire alarm system having a communication function of communicating with another fire alarm system. Communication may be performed wirelessly or by wire.

Further, the alarm device 1 may be configured to be able to communicate with a device other than the fire alarm device. The devices other than the fire alarm are, for example, a mobile terminal (for example, a smartphone) carried by the resident 100, a security monitoring device installed in a house, and the like. The alarm device 1 may notify a mobile terminal, a security monitoring device, or the like of the occurrence of a fire, the occurrence of an internal event, or the like. In this case, dedicated application software is pre-installed in the mobile terminal, security monitoring device, and the like.

(3.3) Modification 3
By the way, the alarm device 1 may have a structure as shown in FIGS. 6A and 6B (modification example 3). The alarm device of this modification has an annular slit 9 recessed upward on one surface 40 of the housing 4 (lower surface in FIG. 6A). The slit 9 is a view of the housing 4 from below. Occasionally, it is formed along the circular outer circumference of the housing 4. The center of the annular slit 9 substantially coincides with the center of the circular outer circumference of the housing 4. The slit 9 has an acoustic hole H1 for guiding an alarm sound to the outside of the housing 4 and a window hole H2 for guiding the illumination light to the outside of the housing 4 on its inner surface (for example, the inner bottom surface). .. The first output unit 11 (speaker) is housed in the housing 4 so as to face the acoustic hole H1. The second output unit 12 is housed in the housing 4 so as to face the window hole H2.

According to this modification, since the acoustic hole H1 and the window hole H2 are provided on the inner surface of the slit 9, these holes are inconspicuous. Therefore, it is possible to shorten the evacuation time while suppressing the appearance of the appearance from being impaired.

(3.4) Other Modifications The same functions as the alarm device 1 (mainly the control unit 10) in the basic example are embodied in a control method, a computer program, a non-temporary recording medium on which the program is recorded, or the like. You may. Here, the execution subject of the alarm device 1 or the control method includes a computer system. The computer system mainly consists of a processor and a memory as hardware. When the processor executes the program recorded in the memory of the computer system, the function as the execution subject of the alarm device 1 or the control method is realized. The program may be pre-recorded in the memory of the computer system, may be provided through a telecommunications line, or may be recorded on a recording medium such as a memory card, optical disk, hard disk drive, etc. that can be read by the computer system. May be provided. The processor of a computer system is composed of one or more electronic circuits including a semiconductor integrated circuit (IC) or a large scale integrated circuit (LSI). A plurality of electronic circuits may be integrated on one chip, or may be distributed on a plurality of chips. A plurality of chips may be integrated in one device, or may be distributed in a plurality of devices.

In particular, in the basic example, the control unit 10 not only determines a fire, but also determines an internal event, generates a PWM signal to be output to an acoustic circuit, generates a control signal to be output to a lighting circuit, and the like. These functions may be distributed and executed by, for example, two or more processors. Further, the first lighting circuit and the second lighting circuit may be configured as, for example, one lighting circuit.

Further, the alarm device 1 of the basic example is realized by one device, but is not limited to this configuration. For example, the functions of the control unit 10, the first output unit 11, the second output unit 12, the fire detection unit 2, the operation unit 3, the operation light 15, the device detection unit 6, the storage unit 7, and various circuits of the alarm device 1. At least one of the functions may be distributed and provided in two or more devices. Further, at least a part of the functions of the alarm device 1 may be realized by, for example, the cloud (cloud computing).
