(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. is not limited.

The disaster prevention equipment 1 of this embodiment performs a notification operation regarding disaster prevention. Here, as an example, it is assumed that the disaster prevention equipment 1 performs a notification operation regarding a fire. That is, the disaster prevention equipment 1 is a fire alarm that outputs a sound such as an alarm sound when a fire occurs. However, the alarm target of the disaster prevention equipment 1 is not limited to fire, and may be CO (carbon monoxide) generated due to gas leakage or incomplete combustion.

As shown in FIG. 5, the disaster prevention equipment 1 is installed on a structure C1 (construction materials such as ceilings and walls). The disaster prevention equipment 1 includes a preliminary notification section X1 and an operation section 3, as shown in FIG. As shown in FIG. 1, the disaster prevention equipment 1 further includes a photoelectric sensor (detection unit 2) for detecting smoke. The detection unit 2 may be a constant temperature sensor that detects heat. Moreover, the detection part 2 may be separate from the disaster prevention equipment 1 . The disaster prevention device 1 may receive information about fire through communication with another disaster prevention device (fire alarm) having the detection unit 2 .

As shown in FIG. 2, the disaster prevention equipment 1 is installed on one surface (ceiling surface or wall surface) of a structure C1 such as a living room, a bedroom, a staircase, a corridor, etc. in a house 200. FIG. The residence may be a detached house or an apartment complex (condominium). Furthermore, the disaster prevention equipment 1 may be installed not only in a house but also in a non-residential structure C1 (a ceiling surface, a wall surface, or the like). Examples of non-residential buildings include office buildings, theaters, movie theaters, public halls, playgrounds, complexes, restaurants, department stores, schools, hotels, inns, hospitals, nursing homes, kindergartens, libraries, museums, art galleries, underground malls, and train stations. , airports, etc.

Here, the preliminary notification unit X1 executes preliminary notification regarding an internal event when an internal event other than an event targeted for disaster prevention (for example, fire) occurs in the disaster prevention equipment 1 . An internal event is an event that can occur in the disaster prevention equipment 1 itself, and includes replacement timing (replacement timing) of the disaster prevention equipment 1, failure in the disaster prevention equipment 1, dead battery, communication error between the disaster prevention equipment 1, and the like. .

The operation unit 3 receives an operation from a user (the resident 300 in FIG. 5, etc.). When the operation unit 3 receives an operation during execution of the preliminary notification, the disaster prevention equipment 1 causes one or a plurality of other disaster prevention equipments 1 to start an operation test including at least a test related to an internal event. In the following, as an example, it is assumed that the disaster prevention device 1 itself that has performed the preliminary notification also starts the operation test.

According to this configuration, even if the user does not know the timing at which the operation test should be performed, there is a high possibility that the operation test will be performed through the preliminary notification. In addition, it becomes unnecessary to carry out an operation test on each of a plurality of disaster prevention devices 1 one by one. Therefore, it is possible to improve the convenience of the operation test.

(2) Details (2.1) Overall Configuration Hereinafter, the overall configuration of the disaster prevention equipment 1 and the disaster prevention system 100 according to this embodiment will be described in detail. Here, the disaster prevention equipment 1 is a battery type fire alarm as an example. However, the disaster prevention equipment 1 is a fire alarm that is electrically connected to an external power supply (for example, a commercial electric power system) and is driven by converting AC power (for example, effective value 100 V) supplied from the external power supply into DC current. There may be.

The disaster prevention system 100 includes a plurality of (five in the illustrated example) disaster prevention devices 1, as shown in FIG. The plurality of disaster prevention devices 1 are so-called interlocking disaster prevention devices, and even if a fire is detected by any of the disaster prevention devices 1, the other disaster prevention devices 1 are interlocked (together with the other disaster prevention devices 1) to produce an alarm sound. It is configured to issue a warning. The disaster prevention device 1 (interlocking source) located at the origin of the fire, for example, issues an audible alarm saying, "This is a view-view fire." On the other hand, the other disaster prevention equipment 1 (interlocking destination) issues an alarm sound that can identify the position of the origin of the fire. It is desirable that any one of the plurality of disaster prevention devices 1 functions as a parent device, and the other remaining disaster prevention devices 1 function as child devices. It is desirable that the disaster prevention device 1 as the parent device stores the identification information of the disaster prevention device 1 as the other child device.

Regardless of the parent device or the child device, each disaster prevention device 1 is designed to output an alarm sound corresponding to the location where it is installed by other disaster prevention devices 1 other than itself. etc.). Each disaster prevention device 1 stores in advance voice messages of a plurality of types of alarm sounds. For example, when a certain disaster prevention device 1 is installed in a living room and detects a fire, the disaster prevention device 1 at the origin of the fire issues an audible alarm saying "View view fire." In addition, the disaster prevention device 1 at the origin of the fire transmits an alarm signal including information on the fact that the fire has occurred and the type of voice message corresponding to its own installation location to the disaster prevention devices 1 of the parent and child devices. Then, based on the received alarm signal, the disaster prevention equipment 1 other than the origin of the fire issues an alarm sound such as "View View, there is a fire in the living room."

Below, it is assumed that all of the plurality of disaster prevention devices 1 are installed on the ceiling surface (one surface of the structure C1) of each room or stairs in the house 200 as in the example of FIG. As a result, the vertical and horizontal directions of the disaster prevention equipment 1 will be defined and explained using the vertical and horizontal arrows shown in FIG. These arrows are merely described for the purpose of assisting the explanation and are not substantial. Moreover, these directions are not the meaning which limits the usage direction of the disaster prevention equipment 1. FIG.

Each disaster prevention device 1, as shown in FIG. It further includes an output unit 13, a battery 14, and a housing 4 (see FIG. 3). The display unit 11 and the sound unit 12 constitute the notification unit 6 . Moreover, the disaster prevention equipment 1 further includes a storage unit 7 .

Each disaster prevention device 1 further includes a communication section 8 (transmitting section 15) for communicating with other disaster prevention devices 1. FIG. The communication unit 8 is a communication interface for wirelessly (or wiredly) issuing an alarm and interlocking operation tests (to be described later) within the disaster prevention system 100 .

(2.2) Housing The housing 4 includes the control unit 10, the display unit 11, the sound unit 12, the output unit 13, the battery 14, the detection unit 2, the storage unit 7, the communication unit 8, the control unit 10 and various A circuit board (not shown) and the like on which circuit components constituting the circuit are mounted are housed inside. Although illustration is omitted, 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, such as flame-retardant ABS resin. The housing 4 is formed in a flat cylindrical shape as a whole. The housing 4 has an attachment portion on its upper surface, and is attached to one surface (installation surface) of the structure C1 by the attachment portion.

The housing 4 has, as shown in FIG. The housing 4 has a partition wall that divides the internal space into two upper and lower parts. The labyrinth and detection unit 2 is located in the first space on the upper side, and the control unit 10, the display unit 11, the sound unit 12, the output unit 13, the battery 14, the storage unit 7, the communication unit 8, the circuit board, etc. are located on the lower side. in the second space of

As shown in FIGS. 3 and 4, the housing 4 has a slit 9 recessed upward in its front surface 402 (lower surface in FIG. 3). The slit 9 has an annular shape along the outer periphery of the housing 4 and having a predetermined groove width. As shown in FIG. 4, the slit 9 has an acoustic hole H1 and a window hole H2 in a first region 91 and a second region 92 of its inner surface 90, respectively. The sound hole H<b>1 is a hole for leading the alarm sound of the sound unit 12 to the outside of the housing 4 , and faces the sound unit 12 inside the housing 4 . In addition, the acoustic hole H1 may be omitted or may not be provided. The window hole H2 is a hole for guiding the light from the output section 13 to the outside of the housing 4 and faces the output section 13 inside the housing 4 . Hereinafter, the light from the output unit 13 may be referred to as "illumination light", but the light from the output unit 13 is weaker in brightness than the illumination light output by general lighting fixtures, for example, and illuminates an evacuation route. It is light of degree.

Furthermore, the housing 4 supports the operation unit 3 on its front surface 402 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 (operation) 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 disk-shaped member having translucency. The operation unit 3 is arranged to face a display unit (operating lamp) 11 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.

(2.3) Notification Unit The notification unit 6 is composed of the display unit 11 and the sound unit 12 as described above. The notification unit 6 has a function of notifying the occurrence of an external event. “Occurrence of an external event” in the present disclosure is, for example, an event targeted for disaster prevention in the disaster prevention equipment 1, that is, the occurrence of a fire. The notification unit 6 also has a function of notifying the occurrence of an internal event other than an external event targeted for disaster prevention in the disaster prevention equipment 1 . The “occurrence of an internal event” in the present disclosure is an event that can occur in the disaster prevention equipment 1 itself, and includes, as an example, occurrence of replacement timing (replacement timing) of the disaster prevention equipment 1 . It is judged that the "time for replacement" has been reached when about 10 years have passed since the disaster prevention equipment 1 was installed (after the power was turned on). After 10 years, the fire prevention equipment 1 may not be able to detect or report a fire due to the end of life of internal electronic parts, battery exhaustion, etc. Therefore, it is recommended to replace the equipment after 10 years as a guideline. In addition, "occurrence of an internal event" includes a failure in the disaster prevention equipment 1 (failure of a circuit component, disconnection, etc.), a dead battery (a state in which the remaining capacity of the battery 14 is low), and a disaster prevention. It also includes the occurrence of communication errors between devices 1 and the like. Battery 14 is, for example, a lithium battery.

The acoustic unit 12 has a function of notifying the occurrence of an internal event and a function of notifying the occurrence of a fire. The acoustic unit 12 outputs sound (sound waves). When the control unit 10 determines that a fire has occurred, the sound unit 12 outputs an alarm sound so as to notify the occurrence of a fire.

The acoustic unit 12 is composed of a speaker that converts an electrical signal into sound. A speaker has a diaphragm and emits an alarm sound by mechanically vibrating the diaphragm according to an electrical signal. The speaker is formed in a circular shape when viewed from the front and has a disk shape. The sound unit 12 outputs an alarm sound (for example, a “beep” sound) under the control of the control unit 10 . It is preferable that the acoustic unit 12 output the alarm sound by changing the loudness (sound pressure level) of the alarm sound. The alert sound may include, for example, a sweeping sound that sweeps from low to high. The audible alarm may include, for example, a voice message such as "There is a fire. There is a fire." Here, it is assumed that the warning sound consists of a sweep sound and a voice message following the sweep sound.

A circuit component constituting, for example, an acoustic circuit is mounted on the circuit board. The acoustic circuit has 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 produces an alarm sound. is output from the acoustic unit 12 as.

When the control unit 10 determines that any internal event has occurred, the sound unit 12 outputs a sound for announcing the occurrence of the internal event. Hereinafter, this sound may also be referred to as "announcement sound" in order to distinguish it from the alarm sound at the time of fire. For example, an example of the notification sound regarding the time to replace the disaster prevention equipment 1 includes a voice message such as "It is time to replace the alarm device." An example of an alarm sound related to a failure includes a voice message such as "A failure has occurred in XX." Also, an example of the notification sound regarding battery exhaustion includes a voice message such as "Battery is exhausted." The notification sound is output at a volume about 60 to 70% of the volume of the warning sound.

The acoustic unit 12 outputs warning sounds and notification sounds on a trial basis even during the operation test. The operation test can be executed by pushing the operation unit 3 or pulling a pull string (not shown) drawn out from the housing 4 .

It should be noted that when the operation unit 3 receives an operation input from the outside during the alarm (while the alarm is being issued), the sound unit 12 stops outputting the alarm sound.

The display unit (operating lamp) 11 has a function of notifying the occurrence of an internal event and a function of notifying the occurrence of a fire. The display unit 11 has a red LED (Light Emitting Diode) 110 mounted on the circuit board as a light source. The display unit 11 is normally turned off (when monitoring a fire), and starts blinking (or turning on) when the control unit 10 determines that a fire has occurred. Hereafter, the flashing that reports the occurrence of fire may be referred to as "operational flashing". The operation flashing stops under the control of the control unit 10 when the warning sound stops.

Circuit parts constituting a first lighting circuit for blinking the LED 110 of the display unit 11 are mounted on the circuit board. The first lighting circuit blinks the LED 110 using DC power discharged from the battery 14 under the control of the control unit 10 . When the disaster prevention device 1 is electrically connected to a commercial power system, the first lighting circuit converts AC power supplied from the power system into DC current to cause the LED 110 to blink.

Light emitted from the display unit 11 is guided to the outside of the housing 4 via the operation unit 3 having translucency. The resident 300 can know that the disaster prevention device 1 is in operation (detecting a fire) by visually recognizing the red operation flashing through the operation unit 3 .

By the way, the display unit 11 is included in the preliminary notification unit X1 in the present disclosure. Under the control of the control unit 10, the preliminary notification unit X1, when an internal event occurs, executes a preliminary notification regarding the internal event. Here, the preliminary notification unit X1 performs preliminary notification regarding replacement by display when the time for replacement of the disaster prevention equipment 1 arrives. In other words, when the control unit 10 determines that the time for replacement of the disaster prevention equipment 1 has arrived, the display unit 11 blinks to notify that the time for replacement has arrived. Hereinafter, this blinking may be referred to as "notification blinking". The display unit 11 may perform notification blinking not only at the time of replacement, but also at the time of failure or battery exhaustion. Note that the flashing periods are different from each other in order to distinguish between the notification flashing and the operation flashing.

The operation test of the display unit 11 can be performed by pushing the operation unit 3 or pulling the pull string, similarly to the sound unit 12 .

On the other hand, the acoustic unit 12 is included in the present notification unit X2 in the present disclosure. Under the control of the control unit 10, the main notification unit X2 executes the main notification regarding the replacement when the operation unit 3 receives an operation while the preliminary notification is being performed by the preliminary notification unit X1. In other words, when the operation unit 3 is pressed while the display unit 11 is performing the preliminary notification (while the notification is flashing), the audio unit 12 outputs a voice message such as "It is time to replace the alarm device." . At this time, with the push operation to the operation unit 3 as a trigger, the operation test is started in conjunction with the disaster prevention device 1 that has received the operation and the other disaster prevention devices 1 . The voice message is output in the operation test. When the operation unit 3 receives another push operation while the main notification is being executed (while the voice message is being output), the sound unit 12 stops the main notification under the control of the control unit 10 .

(2.4) Output Unit Under the control of the control unit 10, the output unit 13 outputs illumination light that illuminates the surrounding area R1 (see FIG. 5: mainly the floor surface) in response to the occurrence of fire. The output unit 13 has one or a plurality of illumination white LEDs 130 mounted on the circuit board as a light source (see FIG. 1). The output unit 13 is normally turned off, and starts turning on (output of illumination light) when the control unit 10 determines that a fire has occurred. Therefore, as shown in FIG. 5, even if a fire breaks out in the middle of the night when the resident 300 is asleep, the resident 300 does not have to turn on the wall switch to turn on the lighting equipment. Using 13 illumination lights, the evacuation route can be visually recognized immediately to evacuate.

The LED 130 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 mounting substrate. The LED chip is preferably, for example, a blue light emitting diode that emits blue light from its light emitting surface. Moreover, 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 the blue light emitted from the LED chip. The LED 130 is configured to emit white illumination light from its light emitting surface when a DC voltage is applied between its anode electrode and cathode electrode. The color of illumination light is not limited to white, and other light colors may be used. However, it is desirable not to overlap the light color of the display unit 11 .

Circuit components constituting a second lighting circuit for lighting the LED 130 of the output section 13 are mounted on the circuit board. The second lighting circuit lights the LED 130 using the DC power discharged from the battery 14 under the control of the control unit 10 . When the disaster prevention device 1 is electrically connected to a commercial power system, the second lighting circuit converts AC power supplied from the power system into DC current to light the LED 130 .

Light (illumination light) emitted from the output unit 13 is led out of the housing 4 through the window hole H2 of the slit 9, and the surrounding area R1 is illuminated. The output unit 13 is also lighted experimentally during the operation test. The operation test of the output unit 13 can be performed by pushing the operation unit 3 or pulling the pull cord, similarly to the sound unit 12 .

(2.5) Detecting Unit The detecting unit 2 detects information related to a fire (external event) to be notified by an alarm sound. Here, the detection unit 2 is, for example, a photoelectric sensor that detects smoke. Thus, the information includes, for example, information about smoke. The 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, as shown in FIG. The light-emitting unit 21 and the light-receiving unit 22 are arranged in the labyrinth of the housing 4 such that the light-receiving surface of the light-receiving unit 22 is off the optical axis of the light emitted from 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 housing 4 .

When there is no smoke in the labyrinth of the housing 4 , the light emitted from the light emitting section 21 hardly reaches the light receiving surface of the light receiving section 22 . On the other hand, when smoke exists in the labyrinth of the housing 4 , the light emitted from the light emitting unit 21 is scattered by the smoke, and part of the scattered light reaches the light receiving surface of the light receiving unit 22 . In other words, the detection unit 2 receives the irradiation light from the light emitting unit 21 scattered by the smoke at the light receiving unit 22 .

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

(2.6) Control Unit The control unit 10 is composed of, for example, a microcontroller whose main components are a CPU (Central Processing Unit) and a memory. In other words, the control unit 10 is realized by a computer having a CPU and memory, and the computer functions as the control unit 10 by the CPU executing a program stored in the memory. Although the program is pre-recorded in the memory here, it may be provided through an electric communication line such as the Internet or recorded in a recording medium such as a memory card.

The control unit 10 controls the display unit 11, the first lighting circuit, the acoustic unit 12, the acoustic circuit, the output unit 13, the second lighting circuit, the detection unit 2, the storage unit 7, the communication unit 8, and the like. The control unit 10 also controls a power supply circuit that generates operating power for various circuits from the DC power of the battery 14 . The storage unit 7 is a rewritable memory, preferably a non-volatile memory. The storage unit 7 may be a memory that the control unit 10 itself has.

The control unit 10 is configured to receive a detection signal from the detection unit 2 and determine whether or not a fire has occurred. Specifically, the control unit 10 monitors the detection signal from the detection unit 2 and determines whether or not the signal level included in the detection signal exceeds the threshold.

The control unit 10 stores threshold values in the storage unit 7 . For example, the control unit 10 may periodically determine whether or not the smoke density exceeds the threshold at predetermined time intervals, and determine that a fire has occurred if the smoke density exceeds the threshold even once. The predetermined time interval is, for example, 5 seconds. Alternatively, the control unit 10 may count the number of times the smoke density has continuously exceeded the threshold value, and determine that a fire has occurred when the number of times reaches a specified number of times. Of course, if the control unit 10 receives a detection signal including information indicating that a fire has broken out from the detection unit 2, the control unit 10 may directly determine that a fire has broken out.

When the control unit 10 determines that a fire has occurred based on the smoke concentration, the control unit 10 causes the sound unit 12 to start outputting an alarm sound. Specifically, the control unit 10 generates a PWM signal corresponding to a sweep sound whose frequency changes linearly over time, and outputs the PWM signal to the acoustic circuit. The PWM signal is converted into an audio signal by an audio circuit, and a sweep sound (warning sound) is output from the audio unit 12 . Also, the control unit 10 generates a PWM signal corresponding to the voice message based on the message data stored in the storage unit 7 and outputs it to the acoustic circuit. The PWM signal is converted into an audio signal by an audio circuit, and an audio message (alarm sound) is output from the audio unit 12 .

When the control unit 10 determines that a fire has occurred, the control unit 10 transmits a control signal for blinking the display unit 11 to the first lighting circuit and a control signal for lighting the output unit 13 to the second lighting circuit. . Upon receiving a control signal from the control unit 10, the first lighting circuit causes the display unit 11 to start blinking. Upon receiving the control signal from the control unit 10, the second lighting circuit lights the output unit 13 with a constant brightness.

The control unit 10 also determines the smoke concentration during the warning (while the warning sound is being issued). If the smoke density becomes equal to or less than the reference value during an alarm, the control unit 10 stops the generation of the PWM signal, stops the output of the alarm sound by the sound unit 12, and outputs the stop signal to the first lighting circuit and the second lighting circuit. The light output from the display section 11 and the output section 13 is also stopped by transmitting to the lighting circuit respectively. That is, when the control unit 10 determines that the fire (smoke) has disappeared, it automatically stops outputting the alarm sound, outputting the illumination light, and blinking the display unit 11 .

Further, the control unit 10 stops outputting the alarm sound when the push button switch in the housing 4 is turned on by pushing the operation unit 3 during the alarm. If the resident 300 judges that the alarm of the disaster prevention equipment 1 is a false alarm, he/she can press the operation unit 3 to stop issuing the alarm sound. The alarm can be stopped by pulling the drawstring.

On the other hand, when the push button switch in the housing 4 is turned on by pushing the operation unit 3 while the alarm is not issued, the control unit 10 executes a predetermined operation test for inspection. The operation test includes a sound output test of the acoustic unit 12, a light output test of the output unit 13, a blinking test of the display unit 11, and the like. A motion test can also be performed by pulling the drawstring.

The control unit 10 is further configured to determine whether an internal event (replacement, failure, dead battery, etc.) has occurred. The determination of whether or not an internal event has occurred will be described in detail below.

The control unit 10 monitors the usage time using a built-in timer. The usage time is, for example, the time during which the power is turned on and the disaster prevention device 1 is in an operating state. The control unit 10 accumulates and stores the usage time in the storage unit 7 . When the cumulative usage time reaches 10 years, the control unit 10 determines that the time for replacement of the own disaster prevention equipment 1 has arrived, and causes the preliminary notification unit X1 (display unit 11) to perform preliminary notification (preliminary notification). notification step). That is, the display unit 11 starts blinking for notification.

FIG. 6A is a diagram showing a state of preliminary notification (blinking of notification). In the illustrated example, the period A3 corresponds to one cycle. The period A3 is, for example, 5 minutes. The display unit 11 repeats the operation of turning on during the period A1 and then turning off during the period A2. The period A1 is, for example, 0.1 seconds, and the period A2 is, for example, 1.9 seconds. After the fourth lighting, the light continues to be turned off for the remaining time, and after the period A3 elapses, the lighting during the period A1 is repeated four times. Note that this notification blinking is merely an example, and is not particularly limited.

Reaching the time for replacement is less urgent than running out of battery or failure, and replacement of the disaster prevention equipment 1 is convenient for the resident 300 as well. Therefore, the control unit 10 does not cause the main notification unit X2 (sound unit 12) to output the main notification, that is, the voice message for notifying the replacement immediately after the determination. Then, when the resident 300 presses the operation unit 3 for the first time during the execution of the preliminary notification, that is, during the blinking of the notification, the main notification is executed (main notification step). In this way, by notifying the arrival of the replacement time in the order of the preliminary notification (light) and the main notification (sound), it is possible to urge the resident 300 to replace without difficulty.

When the operation unit 3 is pushed again (second push operation) by the resident 300 during execution of this notification, the control unit 10 stops outputting the voice message from the sound unit 12 . That is, since the present notification being executed can be stopped according to the convenience of the resident 300, convenience is improved. In addition, it is possible to reduce the power consumed by the continuous execution of this notification.

Note that the control unit 10 causes the preliminary notification unit X1 (display unit 11) to start the preliminary notification until the main notification is started (until the operation unit 3 is pressed for the first time). Make the notification run continuously. Therefore, the possibility of the resident 300 noticing the preliminary notification is improved, and the failure of the resident 300 to replace the battery can be further suppressed.

In addition to monitoring the usage time, the control unit 10 monitors, for example, the current flowing from the acoustic circuit to the acoustic unit 12, and if the current value of the current is an abnormal value (such as zero or a value close to it), disconnection is detected. determined to have occurred. Further, when 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. Further, the control unit 10 may monitor the temperature of various circuits, etc., and determine that a failure has occurred if there is abnormal heat generation. When determining that a failure has occurred, the control unit 10 causes the notification unit 6 to notify. As with the replacement notification described above, the failure notification may be performed in the order of the preliminary notification and the main notification, or the preliminary notification may be omitted and only the main notification may be performed. Note that if there is a disconnection between the acoustic circuit and the acoustic unit 12 , the acoustic unit 12 cannot issue a notification, so that the display unit 11 only issues a notification regarding the failure.

The control unit 10 also monitors the battery voltage of the battery 14 . The control unit 10 preliminarily stores characteristic data in which the battery voltage and the capacity of the battery 14 are associated with each other in the storage unit 7, and if the remaining capacity corresponding to the monitored battery voltage is less than 10% of the capacity, It is determined that the battery has run out. When determining that the battery has run out, the control unit 10 causes the notification unit 6 to notify. As with the replacement notification described above, the notification regarding the battery exhaustion may be performed in the order of preliminary notification and main notification, or the preliminary notification may be omitted and only the main notification may be performed.

The control unit 10 may determine whether or not these internal events occur at predetermined intervals. At least part of the internal events may be determined, for example, 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, and outputs the corresponding voice message via the acoustic circuit. Output from the unit 12 .

(2.7) Re-execution of preliminary notification The preliminary notification unit X1 of each disaster prevention device 1 in this embodiment executes preliminary notification at least one more time when a predetermined condition is met after the main notification is started. . In other words, when the control unit 10 determines that the predetermined condition is satisfied after the main notification is started, the control unit 10 causes the preliminary notification unit X1 (display unit 11) to perform the preliminary notification at least one more time (re-notification step). .

Here, the "predetermined condition" is that a predetermined time T1 has elapsed from a certain point in time tx (see FIG. 7A). The time tx is, for example, the start time t1 of this notification (the time when the operation unit 3 is pressed for the first time) (see FIG. 7A). The predetermined time T1 is four weeks as an example, but is not particularly limited. In the case of FIG. 7A, the second preliminary notification is performed at time t3.

The time point tx may be the end time point t2 of this notification (the time point when the operation unit 3 is pressed for the second time) (see FIG. 7B). In the case of FIG. 7B, the second preliminary notification is performed at time t4.

Alternatively, the time tx may be the preliminary notification start time t0 (see FIG. 7C). In the case of FIG. 7C, the second preliminary notification is performed at time t5. In the example of FIG. 7C, even if the predetermined time T1 has passed, if the first pressing operation to the operation unit 3 has not been performed, the control unit 10 resets the timing of the predetermined time T1 and issues a preliminary notification. It is desirable to continue.

As described above, in this embodiment, when a predetermined condition is satisfied, the preliminary notification is performed at least one more time (at least two times in total, three times if the main notification is also included), so that the resident 300 will not forget to replace the battery. Suppression can be achieved.

In addition, since the preliminary notification is performed by the (lighting) display and the main notification is performed by outputting sound, compared to the case where both the preliminary notification and the main notification are performed by display or both are performed by outputting sound , the resident 300 can be made to recognize the difference between the preliminary notification and the main notification. Moreover, compared with the case where the preliminary notification is performed by outputting sound, it is possible to reduce the possibility of giving discomfort to the resident 300 . Moreover, compared with the case where this notification is performed by display, it is possible to increase the possibility that the resident 300 will notice the notification. In particular, by performing the main notification by sound immediately after performing the operation, it is possible to prevent the resident 300 from failing to hear the main notification by the sound.

Note that the preliminary notification unit X1 may repeatedly perform the preliminary notification when the above predetermined conditions are satisfied after the main notification is started. In short, each disaster prevention device 1 may continue operations such as preliminary notification, main notification, elapse of predetermined time T1, preliminary notification, main notification, elapse of predetermined time T1, preliminary notification, and so on. By repeating the preliminary notification, it is possible to further prevent the resident 300 from forgetting to replace the battery.

By the way, the re-execution may be executed not only for the preliminary notification but also for the main notification. For example, as shown in FIG. 8A, when the operation unit 3 receives an operation after a certain period of time T2 from a specific time tz (time t6), This notification may be executed again. In FIG. 8A, the specific time tz corresponds to the time when the operation unit 3 receives the first operation during execution of the preliminary notification, that is, the start time t1 of the first main notification. However, as shown in FIG. 8B, the specific time tz may be the time when the operation unit 3 receives the second operation during the execution of the first main notification, that is, the end time t2 of the first main notification. .

The fixed period T2 is desirably shorter (eg, 1 day) than the predetermined period of time T1 (eg, 4 weeks), but is not particularly limited. The certain period of time T2 may be the same as the predetermined period of time T1, or may be longer than the predetermined period of time T1.

Further, when the control unit 10 accepts an operation on the operation unit 3 after a certain period of time T2 has elapsed from a specific time tz, if an event having a higher priority than replacement occurs at that time, the notification unit X2 may be caused to report information about its high priority events. Events with a higher priority than replacement include the occurrence of a failure, battery exhaustion, and the like. Naturally, the fire alarm has the highest priority during the alarming of the fire alarm.

In this case, re-execution of this notification or execution of notification of information about an event with high priority can be performed according to the convenience of the resident 300, so convenience is improved.

(2.8) Operation test and interlocking function By the way, in this embodiment, when the first push operation is performed on the operation unit 3 for the disaster prevention device 1 that is executing the preliminary notification, the disaster prevention device 1 immediately Instead of outputting the main notification, that is, outputting a voice message informing of replacement, first, a predetermined operation test is started. Moreover, the plurality of disaster prevention devices 1 are so-called interlocking disaster prevention devices, and although it has been described that they are interlocked to issue alarm sounds, the operation test is also interlocked. In other words, if an operation is received by the operation unit 3 during the execution of the preliminary notification, the operation test is performed not only on the disaster prevention device 1 that received the operation, but also on the disaster prevention device 1 as an interlocking source. An operation test is started for each of the (interlocking destinations) (interlocking step).

An operation test starting from the preliminary notification and an operation related to its interlocking function in the disaster prevention system 100 will be described below with reference to FIG. 6B. As described above, the execution of the operation test itself is performed by performing a specific operation (operation to the operation unit 3, the pull cord, etc.) when the disaster prevention device 1 is in the standby state, even if the preliminary notification is not being performed. is possible.

The operation test includes at least a test related to replacement (confirmation of replacement timing). In this embodiment, the operation test includes, as an example, confirmation of replacement timing of the disaster prevention equipment 1, illumination light output test of the output unit 13, alarm sound output test of the sound unit 12, and lighting of the display unit (operating light) 11. This includes testing, checking the capacity of the battery 14, and checking for failures in various circuits. Also, the operation test may include a communication test between a plurality of disaster prevention devices 1 . For example, the disaster prevention device 1 as the parent device also checks the radio wave intensity, such as whether or not all of the disaster prevention devices 1 as child devices exist within a communicable area.

Here, it is assumed that, among the plurality of disaster prevention devices 1 of the disaster prevention system 100, one disaster prevention device 1, which is a child device, reaches the ten-year replacement time. The disaster prevention equipment 1 starts preliminary notification (see FIG. 6A). It is assumed that the resident 300 who has noticed the preliminary notification performs the first push operation on the operation unit 3 of the disaster prevention device 1 that is executing the preliminary notification at time t10 in FIG. 6B.

The disaster prevention equipment 1 that has received the push operation outputs a voice message such as "beep, testing is in progress" through the acoustic unit 12. FIG. After that, at time t11, the operation test is started.

The disaster prevention device 1 that has received the push operation here becomes the interlocking source, and during the time t10 to t11, the communication unit 8 (transmitting unit 15) to the disaster prevention device 1 of the parent device or the child device: A test signal (interlocking signal) instructing the start of the operation test is sent. When the disaster prevention device 1 of the child device receives the test signal from the interlocking source, the operation test is started as it is. Further, when the master disaster prevention device 1 receives the test signal from the interlocking source, it sends out a test signal instructing the start of the operation test to the child disaster prevention device 1 in the disaster prevention system 100 .

More specifically, in the standby state, each of the disaster prevention devices 1 of the parent device and the plurality of child devices in the disaster prevention system 100 is an asynchronous intermittent reception method, and an alarm when a test signal and an actual fire is detected. The presence or absence of signals such as traffic lights is confirmed. That is, in the present embodiment, the intermittent reception system is adopted in order to suppress the power consumption of the battery 14 in the wireless disaster prevention device 1 with the battery 14 built therein. Then, the disaster prevention device 1 serving as the interlocking source repeats the test signal (the alarm signal when the fire is detected) a plurality of times (for example, three times) and multicasts it to the disaster prevention device 1 of the parent device or other child devices. When the disaster prevention device 1 of the child device receives the test signal, the operation test is started as it is, and when the disaster prevention device 1 of the parent device receives the test signal, a periodic beacon is transmitted to the child device. is started, and the operation test is started in the child device without omission. After that, the disaster prevention equipment 1 of the parent device and the child device communicate with each other by the time division multiple access method until the end of the operation test.

In the example of FIG. 6B, at time t11, all the disaster prevention devices 1 in the disaster prevention system 100 start the operation test almost all at once. Here, as shown in FIG. 6B, the interlocking disaster prevention device 1 continues the preliminary notification until time t11, and stops the preliminary notification at time t11. Note that the preliminary notification does not have to be stopped at time t11, and may be at time t10 when the first pressing operation is performed.

At time t11, each disaster prevention device 1 notifies the result of the operation test from the acoustic unit 12 together with a beep sound of "beep, beep, beep, beep". Since the interlocking disaster prevention device 1 has reached the replacement time, it outputs (main notification) the voice message "Beep, beep, beep, beep, it's time to replace the alarm." . That is, time t11 corresponds to start time t1 of this notification in FIG. 7A, that is, "a certain time tx". For example, when it is confirmed that the remaining capacity of the battery 14 is low in the other disaster prevention device 1 that is the interlocking destination, a voice message such as "Beep, beep, beep, beep, the battery is dead." Output.

Each disaster prevention device 1 may report only the highest priority event as a test result if it is found by the operation test that an event other than the arrival of the replacement time, such as a failure or a dead battery, has occurred. Then, all the test results may be reported sequentially. Since the operation test is based on the preliminary notification, at least the interlocking disaster prevention equipment 1 has reached the replacement time. If there is no failure, etc., a voice message of "beep, it's normal" is output. These voice messages are repeatedly output, for example, at intervals of 4 seconds until the operation test is completed.

Also, at time t11, each fire prevention device 1 performs a lighting test from the display section (operating lamp) 11 in parallel with notification of the test result. For example, the display unit 11 periodically repeats turning on for 0.5 seconds and turning off for 0.5 seconds.

Also, at time t11, each disaster prevention device 1 performs an illumination light output test from the output unit 13 in parallel with the notification of the test result. That is, the output unit 13 of each disaster prevention device 1 starts outputting illumination light, triggered by receiving the first push operation on the operation unit 3 of the disaster prevention device 1 that is the interlocking source. The output unit 13 performs continuous lighting.

As described above, in the present embodiment, it is possible to perform an operation test of a plurality of other disaster prevention devices 1 starting from a preliminary notification of a certain disaster prevention device 1 , that is, when the time for replacement is reached. Therefore, even if the resident 300 does not know the timing at which the operation test should be performed, it is highly likely that the operation test will be performed through the preliminary notification. In addition, it becomes unnecessary to carry out an operation test on a plurality of disaster prevention devices 1 one by one, and convenience regarding the operation test can be improved.

The operation test described above (notification of the test result, lighting test of the display unit 11, output test of the illumination light of the output unit 13, etc.) ends when the operation unit 3 is pressed for the second time. That is, when the disaster prevention device 1 of the interlocking source receives the operation again with the operation unit 3 during execution of this notification, the disaster prevention device 1 stops this notification, Device 1 is caused to stop reporting the test results. Therefore, starting from the operation of the operation unit 3 of the disaster prevention device 1, it is possible to cause other disaster prevention devices 1 to stop reporting the test results. In addition, since notification of the results of the test being executed can be stopped all at once according to the convenience of the residents 300, convenience is improved. In addition, it is possible to reduce the power consumed by continuing to report the test results.

Similarly, the output unit 13 of each disaster prevention device 1 stops outputting illumination light when the operation unit 3 of the interlocking disaster prevention device 1 receives an operation again while the illumination light is being output. Therefore, it is possible to realize interlocking regarding this notification and the illumination light.

FIG. 6B shows an example in which the resident 300 presses the operation unit 3 at time t12. If the operation unit 3 is not pressed for, for example, one minute at most from time t11, the operation test is automatically terminated. In the above explanation example, the operation test starts with the push operation to the operation unit 3 of the disaster prevention equipment 1 that executed the preliminary notification and stops interlocking. Even if the pressing operation of is the starting point, the interlocking stop is possible. In short, the disaster prevention equipment 1 targeted for the first push operation and the second push operation may be different from each other.

Then, at time t13 when a predetermined time T1 has elapsed from time t11 when the main notification is started, the disaster prevention device 1, which is the interlocking source, performs the preliminary notification again. Even in the second and subsequent preliminary notifications, when the operation unit 3 is pressed, the operation test is performed again on each disaster prevention device 1 .

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. Moreover, the function similar to the disaster prevention equipment 1 which concerns on the said embodiment may be embodied by the non-temporary recording medium etc. which recorded the control method of the disaster prevention equipment 1, a computer program, or a computer program.

Modifications of the above embodiment are listed below. Modifications described below can be applied in combination as appropriate. In addition, below, the said embodiment may be called a "basic example."

The control unit 10 of the disaster prevention equipment 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 as the control unit 10 of the disaster prevention device 1 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). Furthermore, an FPGA (Field-Programmable Gate Array), which 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, shall 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.

In addition, it is not an essential configuration of the disaster prevention equipment 1 that a plurality of functions of the disaster prevention equipment 1 are integrated in one housing, and the components of the disaster prevention equipment 1 are provided dispersedly in a plurality of housings. may be Furthermore, at least some functions of the disaster prevention equipment 1, for example, some functions of the disaster prevention equipment 1 may be realized by the cloud (cloud computing) or the like. On the contrary, like the basic example, a plurality of functions of the disaster prevention equipment 1 may be integrated in one housing.

In the basic example, the preliminary notification is executed when an internal event such as arrival of replacement time occurs. However, the preliminary notification may be executed when an internal event such as battery exhaustion occurs other than the arrival of the replacement time.

In the basic example, each disaster prevention device 1 is configured to re-execute the preliminary notification at least once, but re-executing the preliminary notification is not an essential configuration in the present disclosure. Each disaster prevention device 1 does not have to re-execute the preliminary notification.

In the basic example, the preliminary notification unit X1 (display unit 11) continuously provides the preliminary notification from the start of the preliminary notification until the main notification is started (until the operation unit 3 is pressed). to execute. However, the preliminary notification unit X1 may stop the preliminary notification when a specified period of time elapses without receiving an operation on the operation unit 3 after starting the preliminary notification. In this case, it is possible to reduce the possibility of giving discomfort to the resident 300 compared to the case where the execution of the preliminary notification is maintained as in the basic example. In addition, it is possible to reduce the power consumed by the continuous execution of the preliminary notification.

In addition, it is preferable that the preliminary notification unit X1 restarts the preliminary notification after the specific period has passed since the preliminary notification was stopped according to the lapse of the specified period. By starting the preliminary notification again, it is possible to reduce the possibility of giving discomfort to the resident 300 and further suppress the resident 300 from forgetting to replace.

In the basic example, the preliminary notification is performed by display and the main notification is performed by outputting sound, but this is not the only option. For example, both the preliminary notification and the main notification may be sound output, in which case the volume of the preliminary notification and the main notification may be different, and the content of the output voice message may be different.

In the basic example, the disaster prevention equipment 1 includes an output unit 13 that outputs illumination light. However, the output unit 13 is not an essential component for the disaster prevention equipment 1 . The disaster prevention equipment 1 does not have to include the output unit 13 .

In the basic example, the display unit 11 serves both as an operating light (operating blinking) and a preliminary notification (notifying blinking), but the operating light may be provided separately from the display unit 11 . Further, the light of the display unit 11 is configured to be visible through the operation unit 3 having translucency. However, the operation unit 3 may be an opaque member, and in this case, the light of the display unit 11 is emitted to the outside of the housing 4 from a hole or translucent cover located at a different position from the operation unit 3. may be

In the basic example, the configuration in which the operation test continues after the preliminary notification has been described. Testing may begin. Also at this time, the disaster prevention device 1 may be the interlocking source, and the operation test may be started in another disaster prevention device 1 .

In the basic example, the operation test is also performed by the disaster prevention device 1 itself that has received the operation, but it does not have to be performed by itself. That is, the disaster prevention equipment 1 may simply output a voice message such as "It is time to replace the alarm device" as the main notification immediately after accepting the operation.
