  The audio output unit 20 is an audio output processing unit that outputs an alarm sound or the like via the speaker 19 in response to an instruction from the control unit 24. Here, the volume of the alarm sound can be changed. For example, the volume of the alarm sound can be changed in two stages by changing the voltage applied to the speaker 19 by the audio output unit 20 in accordance with an instruction from the control unit 24 ( Hereinafter, of the two levels, a large volume (for example, 85 dB) is referred to as “large volume”, and a small volume (for example, 70 dB) is referred to as “small volume”).

  The microphone 21 and the voice input unit 22 are means for receiving voice input such as a user's voice and converting it into a voice signal.

  The interlocking transmission / reception unit 23 transmits an alarm signal to another alarm device 1 via the interlocking lead wire 2 in response to an instruction from the control unit 24, while receiving an alarm signal from the other alarm device 1. It is a processing unit.

  The control unit 24 is a control unit that performs various controls in the alarm device 1. The specific configuration of the control unit 24 is arbitrary. For example, the control unit 24 can be configured as a CPU (Central Processing Unit) that calls, analyzes, and executes a program stored in the storage unit 17. In the present embodiment, the control unit 24 includes a detection processing unit 25, an alarm processing unit 26, an interlocking processing unit 27, and an inspection processing unit 28.

  Among these, the detection processing unit 25 determines whether there is a fire, a gas leak, and an incomplete combustion based on the detection values (smoke concentration and gas concentration) input from the fire detection unit 15 and the gas detection unit 16. It is a processing part to judge. Schematically, when a detection value is input from the fire detection unit 15 or the gas detection unit 16, it is compared with a detection threshold value stored in advance in the storage unit 17, and if the detection value exceeds the detection threshold value. The alarm signal is output to the alarm processing unit 26 and the interlocking processing unit 27.

  Further, the alarm processing unit 26 is a processing unit that issues an alarm of fire occurrence, gas leakage, or incomplete combustion based on an alarm signal from the detection processing unit 25.

  The interlock processing unit 27 is a processing unit that transmits an alarm signal to the other alarm devices 1 based on the alarm signal from the detection processing unit 25. Schematically, when an alarm signal is input from the detection processing unit 25, it is transmitted to another alarm device 1. Further, the interlock processing unit 27 performs an interlock alarm based on an alarm signal received from another alarm device 1 via the interlock transmission / reception unit 23. Specifically, when an alarm signal is input from the interlocking transmission / reception unit 23, the alarm signal is output to the alarm processing unit 26, thereby causing the speaker 19 to ring through the alarm processing unit 26 and the fire alarm lamp. 10. The gas alarm lamp 11 or the incomplete combustion alarm lamp 12 blinks or lights up. In addition, when an alarm stop process is performed on a predetermined alarm device 1, other alarm devices are also stopped in conjunction with each other. However, the alarm device 1 is activated by various lighting lamps, blinking, display colors, etc. It is desirable to be able to know whether it is a link source or a link destination.

  The inspection processing unit 28 is a means for performing a predetermined process for executing an inspection operation and a predetermined operation other than the inspection operation according to the operation method when the inspection switch 5 is operated. Yes, corresponding to “inspection processing means” in the claims. Schematically, the inspection processing unit 28 records alarm messages, inspects, stops alarm output, changes threshold values for abnormality detection, outputs history information, and other alarm devices 1 according to the operation method of the inspection switch 5. The inspection operation is executed and the output amount is changed. Specific contents of these processes will be described later. FIG. 5 shows a correspondence example between the operation method of the inspection switch 5 and the contents of the processing performed by the inspection processing unit 28.

(D) Alarm Message Storage Processing Next, alarm message storage processing in the alarm device 1 configured as described above will be described. The alarm message storage process is a process for recording an arbitrary voice message as an alarm sound output when an abnormality is detected in the alarm device 1. FIG. 6 is a flowchart of the alarm message storage process.

  First, the inspection processing unit 28 monitors the presence / absence of an operation of the inspection switch 5 and the operation method thereof, thereby monitoring the presence / absence of an alarm message recording request (step SA-1, “inspection start step in claims”). ”). For example, as illustrated in FIG. 5, when the inspection switch 5 is pulled for a short time within 0.5 seconds and at least three times within a predetermined time, it is determined that there is a request for recording an alarm message. To do. As described above, it is determined that there is a recording request only when the check switch 5 is pulled more than once. This is because an unnecessary warning message is recorded when the inspection switch 5 is pulled only once or twice due to mischief. This is to prevent it.

  Then, as illustrated in FIG. 6, when it is determined that such a recording request has been made (Yes in step SA-1), the inspection processing unit 28 is input via the microphone 21 and is input to the audio output unit 20. The voice message information converted into an electrical signal is stored in the storage unit 17 (step SA-2, corresponding to “inspection processing step” in the claims). This storage process is performed continuously for a predetermined time (No at Step SA-3), and when the predetermined time has elapsed (Yes at Step SA-3), the recording is terminated. This completes the alarm message storage process. That is, from the user side, after operating the inspection switch 5 by a predetermined method, this message can be recorded by saying an arbitrary message to the microphone 21 of the alarm device 1 within a predetermined time. In addition, when the steady background noise level is memorize | stored with the microphone 21 and a warning is output, a warning output can also be controlled according to the said background noise level. For example, the output level can be determined by adding a predetermined output level to the stored background noise level.

  Then, by recording an arbitrary alarm message in this way, an abnormal alarm can be more effectively performed. For example, since the child reacts particularly sensitively to the mother's voice, the mother can record an alarm message, so that an abnormal alarm can be more effectively given to the child. Alternatively, when a foreigner is expected to be present in the monitoring area, the alarm message for the foreigner can be more effectively provided by recording the warning message in a foreign language. A specific reproduction process of the message thus recorded will be described later.

(E) Alarm processing Next, alarm processing according to the present embodiment will be described. The alarm process is a process for executing an alarm operation in the interlocking source alarm device 1 that detects the abnormality when the alarm device 1 detects the abnormality. FIG. 7 is a flowchart of the alarm process.

  As illustrated in FIG. 7, the detection processing unit 25 of the alarm device 1 monitors the presence or absence of input of detection values from the fire detection unit 15 and the gas detection unit 16 (step SB-1), and the detection value is When input (Yes at Step SB-1), it is determined whether or not the detected value exceeds a detection threshold value stored in the storage unit 17 (Step S2). If the detection value does not exceed the detection threshold value, the detection processing unit 25 proceeds to step SB-1 and waits for input of the next detection value (No in step SB-2). On the other hand, when it is determined in step SB-2 that the detected value exceeds the detection threshold (Yes in step SB-2), the detection processing unit 25 sends an alarm signal to the alarm processing unit 26.

  This alarm signal includes abnormality type information. Specifically, when the detection value from the fire detection unit 15 exceeds the fire detection threshold, type information indicating that it is a fire alarm is included, and the detection value from the gas detection unit 16 is the gas detection. If the threshold is exceeded, type information indicating that the alarm is for gas is included, and if the detected value from the gas detector 16 exceeds the incomplete combustion threshold, an alarm for incomplete combustion is included. Is included.

  Upon receiving such an alarm signal, the alarm processing unit 26 executes a predetermined alarm operation. In other words, the transfer alarm signal is output to another alarm device 1 via the interlocking transmission / reception unit 23 (step SB-3). As a result, the other alarm device 1 starts a linked alarm process described later. The alarm processing unit 26 blinks or lights the fire alarm lamp 10, the gas alarm lamp 11, or the incomplete combustion alarm lamp 12 via the display output unit 18 according to the type information included in the alarm signal. At the same time, the speaker 19 is sounded through the audio output unit 20 to output an alarm sound (step SB-4). That is, the fire alarm lamp 10 is flashed or lit when a fire is detected, the gas alarm lamp 11 is detected when a gas leak is detected, and the incomplete combustion alarm lamp 12 is flashed when incomplete combustion is detected.

  As the warning sound output here, a voice message stored in the storage unit 17 in the previous warning message storage process can be used. That is, the alarm processing unit 26 can call out the voice message information stored in the storage unit 17 and output it from the speaker 19 via the voice output unit 20. As a result, an alarm can be issued with an arbitrary message. Alternatively, when the alarm message storage process is not performed (when any message is not stored), a default message stored in advance in the storage unit 17 is output. For example, a message “alarm activated” can be output following the siren sound “Woo Woo”.

  When the alarm is output in this way, the alarm processing unit 26 outputs a signal indicating that to the audio output unit 20 in order to output the alarm sound at a high volume. Then, the audio output unit 20 applies a predetermined voltage for outputting at a high volume to the speaker 19, and the speaker 19 outputs an alarm sound at a high volume. The reason why the alarm sound is output at a large volume in this way is to provide an alarm as reliably and in a wide range as possible for an abnormal situation such as a fire.

  In Step SB-4, the alarm processing unit 26 acquires sounds around the alarm device 1 via the microphone 21 and the voice input unit 22 and stores them in the storage unit 17. Thereby, the sound around the alarm device 1 at the time of abnormality detection can be recorded. At this time, the alarm processing unit 26 obtains information indicating the date and time at that time by a known method (for example, by incorporating a time measuring device in the alarm device), and this date and time information is obtained from the alarm device 1. Is stored in the storage unit 17 in association with the surrounding sounds. This makes it possible to easily identify the date and time when an abnormality is detected.

  Next, after giving an alarm, the alarm processing unit 26 updates the operation history information (step SB-5). For example, the alarm processing unit 26 sets a flag indicating that a fire alarm has been performed when performing a fire alarm, and sets a flag indicating that a gas alarm has been performed when performing a gas alarm, When an incomplete combustion warning is given, a flag indicating that the incomplete combustion warning is given is set.

  Thereafter, the inspection processing unit 28 monitors the presence / absence of the operation of the inspection switch 5 and the operation method thereof, thereby monitoring the presence / absence of the alarm sound stop operation (step SB-6, “inspection start step in claims”). ”). That is, the alarm device 1 may emit an alarm sound other than when an abnormality other than a true abnormality occurs. For example, when the alarm device 1 is installed in a kitchen, a fire alarm may be issued by detecting a large amount of smoke from grilled fish. In such a case, the user can manually stop the alarm 1 from ringing, and unnecessary alarm output can be avoided. For example, when the user pulls the inspection switch 5 (Yes in Step SB-6), the inspection processing unit 28 controls the audio output unit 20 to stop the alarm sound for a predetermined time (Step SB-7, claims). Corresponds to the “inspection processing step”).

  Here, the alarm sound may be stopped only when the user pulls the inspection switch 5 for a predetermined time or longer (for example, 0.5 seconds or longer). If it is, the user is unlikely to accidentally pull the inspection switch 5, and it is expected that the user wants to immediately stop the alarm sound. For this reason, as illustrated in FIG. 5, it is preferable to stop the alarm sound when the user pulls the inspection switch 5 even for a short time.

  When the alarm sound is stopped in this manner, the interlock processing unit 27 outputs an interlock stop signal to another alarm device 1 via the interlock transmission / reception unit 23 (step SB-8). Accordingly, the other alarm device 1 temporarily stops the alarm sound in the interlocked alarm process described later.

  Moreover, the warning process part 26 memorize | stores warning stop log | history information in the memory | storage part 17 (step SB-9). That is, when the alarm sound is stopped for the first time, “alarm stop history information = 1” is stored, and thereafter, every time the alarm sound is stopped, “alarm stop history information = alarm”. Once per hour is added as “stop history information + 1”. Accordingly, the storage unit 17 stores the cumulative number of times that the alarm sound has been stopped as alarm stop history information.

  The reason why the cumulative number is stored in this way is to change the detection threshold based on the cumulative number, as will be described later. However, when such a detection threshold changing function is not necessary, for example, when it is desired to output only a history that the alarm sound has been stopped once or more, as will be described in the inspection process described later. Only information indicating that the stop operation has been performed (for example, a predetermined flag indicating that the stop operation has been performed) may be stored in the storage unit 17.

  Next, the inspection processing unit 28 calls the accumulated number of times that the alarm sound has been stopped and the number of times information for determining whether the detection threshold needs to be changed from the storage unit 17, and the accumulated number of times of alarm stop is predetermined. It is determined whether or not the number of times has been exceeded (step SB-10). If the cumulative number does not exceed the predetermined number (No at Step SB-10), the process proceeds to Step SB-12. On the other hand, when the cumulative number exceeds the predetermined number (Yes in Step SB-10), the detection threshold value stored in the storage unit 17 is changed (Step SB-11, “inspection processing step” in the claims). Corresponding). This is because when a certain number of alarm sound stop operations are performed, the detection threshold is not appropriate in the monitoring area where the alarm sound is installed (for example, a fire or gas leak has not actually occurred). Therefore, by changing the detection threshold, it is intended to reduce unnecessary alarm operations thereafter. A specific method for changing the detection threshold is arbitrary. For example, a change detection threshold (> initial detection threshold) is stored in the storage unit 17 in advance, and the change detection threshold is set as a new detection threshold. May be set. Alternatively, a new detection threshold value may be calculated by adding a predetermined increase amount to the detection threshold value or integrating a predetermined increase rate with respect to the detection threshold value.

  After such processing, the inspection processing unit 28 determines whether or not a predetermined stop time (for example, 5 minutes) has elapsed (step SB-12). And when predetermined time passes, it transfers to following step SB-13 (step SB-12 affirmation). In step SB-13, the alarm processing unit 26 determines whether or not the abnormality detected in step SB-2 continues (step SB-13). That is, it is determined whether or not the detection value at that time exceeds the detection threshold.

  And when abnormality continues (step SB-13 affirmation), it returns to step SB-3 and outputs an interlocking transmission signal continuously, and the alarm in the other alarm device 1 is continued (step SB-). 3). Further, the fire alarm lamp 10 is blinked or turned on again, and the speaker 19 is sounded again to output an alarm sound (step SB-4). As a result, if there is an abnormality even after the alarm sound has been stopped for a predetermined time, an alarm can be issued again to alarm the abnormality.

  On the other hand, when the abnormality does not continue (No at Step SB-13), the normal monitoring state is restored (Step SB-14). That is, the alarm processing unit 26 turns off the fire alarm lamp 10, the gas alarm lamp 11, or the incomplete combustion alarm lamp 12 that has been blinking or turned on via the display output unit 18. Further, the alarm processing unit 26 stops the ringing by the speaker 19 via the audio output unit 20 (in the case where the output of the alarm sound has already been stopped by the stop operation, the fire alarm lamp 10, the gas alarm lamp) 11 or only turning off the incomplete combustion alarm lamp 12). As a result, the alarm device 1 resumes monitoring for the next occurrence of abnormality. This completes the alarm process.

(F) Interlocked alarm process Next, the interlocked alarm process according to the present embodiment will be described. The interlocked alarm process is a process for executing an alarm operation in the interlocking destination alarm device 1 that has received the interlocking transfer signal from the interlocking source alarm device 1 that has detected an abnormality. FIG. 8 is a flowchart of the interlocked alarm processing.

  As illustrated in FIG. 8, the interlock processing unit 27 of the interlocking destination alarm device 1 monitors the presence or absence of the interlocking transfer signal from the interlocking source alarm device 1 (step SC-1). And when the interlocking transmission signal from the interlocking source alarm device 1 is received via the interlocking transmission / reception unit 23 (Yes in step SC-1), the interlocking processing unit 27 indicates that the interlocking transmission signal has been received. It is sent to the alarm processing unit 26.

  Then, the alarm processing unit 26 performs a predetermined alarm operation at the time of the linked transfer. That is, the speaker 19 is sounded through the audio output unit 20 to output an alarm sound (step SC-2). Here, the alarm processing unit 26 outputs a signal indicating that to the audio output unit 20 in order to output the alarm sound at a predetermined loud volume. Then, as in the case of the alarm process, the speaker 19 outputs an alarm sound at a high volume, and alarms an abnormal situation such as the occurrence of a fire as reliably and in a wide range as much as possible.

  As an alarm sound output here, the voice message memorize | stored in the memory | storage part 17 of the said alarm device 1 of the interlocking | linkage destination in the previous alarm message memory | storage process can be used. Alternatively, when the alarm message storage process is not performed (when any message is not stored), a default message stored in advance in the storage unit 17 is output. For example, following the siren sound “Woo Woo”, a message “Another alarm has been activated” is output.

  After the alarm is thus performed, the inspection processing unit 28 monitors the presence / absence of the stop operation by monitoring the presence / absence and operation method of the inspection switch 5 (step SC-3). When the user pulls the inspection switch 5 of the interlocked alarm device 1 (corresponding to the “inspection start step” in the claims), the inspection processing unit 28 controls the audio output unit 20 to alarm The sound is stopped (step SC-4, corresponding to “inspection processing step” in the claims). Here, as in the case of the alarm process, the alarm sound may be stopped only when the user pulls the inspection switch 5 for a predetermined time or longer (for example, 0.5 seconds or longer).

  In addition, in step SC-3, the linkage processing unit 27 monitors the presence or absence of a message stop signal from the linkage source alarm device 1 (step SC-3). That is, when the user pulls the inspection switch 5 of the interlocking source alarm device 1 to output a message stop signal from the interlocking source alarm device 1 (Yes in step SC-3, “Inspection” in the claims) (Corresponding to the “starting step”), the linkage processing unit 27 sends a message to that effect to the inspection processing unit 28, and the inspection processing unit 28 controls the audio output unit 20 to stop the alarm sound (step SC-4, patent). Corresponding to “inspection processing step” in the claims). As described above, the alarm sound may be stopped only through the interlocking alarm device 1, and in this case, the operation of the inspection switch 5 in the interlocking alarm device 1 may be ignored.

  After the alarm stop process is thus performed, the inspection processing unit 28 determines whether or not a predetermined stop time (for example, 5 minutes) has elapsed (step SC-5). And when predetermined time passes, it transfers to following step SC-6 (step SC-5 affirmation). In this step SC-6, the alarm processing unit 26 determines whether or not the interlocking transmission signal detected in step SC-1 is continuously output from the other alarm devices 1 (step SC-6). . If the interlocking transfer signal continues (Yes at step SC-6), the process returns to step SC-2, and the speaker 19 is sounded again to output an alarm sound (step SC-2). As a result, even when the alarm sound is stopped for a predetermined time, if there is an interlocking transfer, the alarm can be performed again and an abnormality can be alarmed.

  On the other hand, when the interlocking transmission signal is not continued (No at Step SC-6), the normal monitoring state is restored (Step SC-7). That is, the alarm processing unit 26 stops ringing by the speaker 19 via the audio output unit 20. As a result, the alarm device 1 resumes monitoring for the next occurrence of an abnormality or the interlocking transfer signal. This completes the interlocked alarm processing.

(G) Inspection Process Next, the inspection process according to the present embodiment will be described. The inspection process is a process executed by the maintenance company for confirming the normality of the function of the alarm device 1, and is a process in the alarm device 1 that has received an inspection request operation. FIG. 9 is a flowchart of the inspection process.

  First, the inspection processing unit 28 monitors the presence / absence of the inspection request and the content of the inspection by monitoring the presence / absence of the operation of the inspection switch 5 and the operation method thereof (step SD-1, “inspection” in the claims). Corresponds to “Startup Step”). Here, specifically, as the request contents, (1) whether the inspection request contents are a single inspection request (inspection request only for the alarm device 1 to which the inspection switch 5 belongs) or an interlocked inspection request. (2) Whether the volume of the alarm sound at the time of the inspection is a low volume or a large volume. Monitor.

  For example, as illustrated in FIG. 5, this monitoring can be performed based on whether or not the inspection switch 5 is pulled, how many seconds it is pulled, and how many times it is pulled within a predetermined time. If the inspection switch 5 is pulled for a short period of time shorter than 0.5 seconds, it is determined that the inspection is not requested and no processing is started (No in step SD-1).

  In addition, the inspection processing unit 28 determines that an independent inspection request has been made when the inspection switch 5 is continuously pulled for a time period of 0.5 seconds or longer and less than 5 seconds. At this time, if the inspection switch 5 is pulled only once within a predetermined time, it is determined that a single inspection at a low volume is required, and the inspection switch 5 is pulled twice or more within a predetermined time. Concludes that a single inspection at a high volume was required.

  The inspection processing unit 28 determines that an interlocked inspection request has been made when the inspection switch 5 is continuously pulled for 5 seconds or more. At this time, if the inspection switch 5 is pulled only once within a predetermined time, it is determined that a synchronized inspection at a low volume is requested, and the inspection switch 5 is pulled more than once within the predetermined time. Determines that an interlocking inspection at a high volume is required.

  Such a plurality of monitoring is performed for the following reason. That is, it is unnecessary when the inspection switch 5 is pulled for a short time by mischief by judging that the inspection switch 5 is requested only when the inspection switch 5 is pulled for a predetermined time or longer (0.5 seconds in this example). Alarming is prevented. Further, by distinguishing between single and interlocking, it is possible to request either independent or interlocking depending on the operation method of the inspection switch 5. In addition, as described above, the alarm sound when an abnormality is detected is set to a high volume level in order to warn the abnormal situation such as the occurrence of a fire as reliably and widely as possible. In the case of a sound, there is a risk that an alarm sound will be heard even in the vicinity, causing unnecessary worry. For this reason, at the time of inspection, in principle, it is preferable to issue an alarm at a lower volume than when an abnormality is detected. However, even at the time of inspection, there is a case where it is desired to check the normality of the alarm output function at a large volume. In this case, it is preferable to issue an alarm at a large volume as when an abnormality is detected. In view of such a point, the alarm device 1 according to the present embodiment can perform inspection by selecting one of the small volume and the large volume.

  As a result of such monitoring, as illustrated in FIG. 9, when there is an inspection request (Yes at Step SD-1) and it is a linked inspection request (No at Step SD-2), the inspection processing unit 28 Then, an interlocking inspection signal is sent to the other alarm device 1 via the interlocking processing unit 27 (step SD-3, corresponding to “inspection processing step” in the claims). This interlocking inspection signal includes information indicating the volume of the alarm sound. On the other hand, if there is an inspection request (Yes at Step SD-1) and it is a single inspection request (Yes at Step SD-2), the inspection processing unit 28 proceeds to Step SD-4. If the inspection request is a small volume (Yes at step SD-4), the inspection processing unit 28 blinks or lights the fire alarm lamp 10, the gas alarm lamp 11, and the incomplete combustion alarm lamp 12. The alarm sound is output from the speaker 19 at a low volume via the audio output unit 20 (step SD-5, corresponding to “inspection processing step” in the claims).

  On the other hand, when the inspection request is at a large volume (No at Step SD-4), the inspection processing unit 28, via the alarm processing unit 26, fire alarm lamp 10, gas alarm lamp 11, and incomplete combustion. The alarm lamp 12 blinks or lights up, and an alarm sound is output from the speaker 19 at a high volume via the audio output unit 20 (step SD-6, corresponding to “inspection processing step” in the claims). As the alarm sound in these steps SD-5 and SD-6, for example, a voice message “Alarm activated” is output after a siren sound “Woo Woo”, and this is repeated twice in total. Or the arbitrary message memorize | stored in the memory | storage part 17 in the alarm message memory | storage process mentioned above can also be used. Thereby, the maintenance company can confirm that the fire alarm lamp 10, the gas alarm lamp 11, the incomplete combustion alarm lamp 12 and the speaker 19 are functioning normally.

  When the output of the alarm sound is completed (Yes at step SD-7), the alarm processing unit 26 turns off the fire alarm lamp 10, the gas alarm lamp 11, and the incomplete combustion alarm lamp 12, and generates an alarm sound. Stop (step SD-8). Then, the inspection processing unit 28 calls the operation history information and the alarm stop history information from the storage unit 17 and displays them (step SD-9, corresponding to “inspection processing step” in the claims). Although the specific method of this display is arbitrary, for example, regarding the operation history information, if there is a fact that a fire alarm is given, the fire alarm lamp 10 is used. If there is a fact that a complete combustion alarm is given, the incomplete combustion alarm lamp 12 is blinked for a predetermined time.

  That is, when the flag indicating that the fire alarm has been performed is set, the fire alarm lamp 10 is performed, and when the flag indicating that the gas alarm has been performed is set, the gas alarm lamp 11 and the incomplete combustion alarm are performed. When the flag indicating that the operation has been completed is set, the incomplete combustion alarm lamp 12 is blinked. Thus, the maintenance company can easily confirm whether or not an abnormality has been detected in the past. That is, for example, when a gas leak is detected by the alarm device 1 provided in the kitchen, a gas company worker rushes to the site, but in the case of a temporary gas leak, the alarm device 1 has already been restored. , History may not remain. Even in such a case, according to the alarm device 1 of the present embodiment, the worker can grasp that the gas leak has been detected as described above, and when the gas leak frequently occurs, It is possible to make a guess that there is a problem.

  As for the alarm stop history, for example, if there is a fact that an alarm stop operation has been performed, the power lamp 13 blinks for a predetermined time. Thereby, the maintenance company can easily confirm whether or not an alarm stop operation has been performed in the past.

  Further, the inspection processing unit 28 outputs the sound around the alarm device 1 stored in the storage unit 17 in the previous alarm processing from the speaker 19 via the audio output unit 20 (step SD-9, claim). Corresponding to “inspection processing step” in the range of As a result, the state around the alarm device 1 at the time of abnormality detection can be audibly communicated to the maintenance company, and the cause of the abnormality or false alarm can be identified more easily and accurately. At this time, the inspection processing unit 28 calls the date and time information stored in association with sounds around the alarm device 1 from the storage unit 17 and outputs the date and time from the speaker 19 via the audio output unit 20. For example, date information is output as “March 31, 12:15”. This makes it possible to easily identify the date and time when an abnormality is detected.

  When such a series of displays and outputs are completed (Yes at Step SD-10), the inspection processing unit 28 returns the alarm device 1 to a normal monitoring state (Step SD-11). That is, the operation history display and the alarm stop history display are ended by turning off the fire alarm lamp 10, the gas alarm lamp 11, the incomplete combustion alarm lamp 12, and the power lamp 13. This completes the single alarm process.

(H) Interlocked inspection processing Next, the interlocked inspection processing according to the present embodiment will be described. The interlocked inspection process is a process executed by the maintenance company in order to confirm the normality of the function of the alarm device 1. In the interlocked alarm device 1 other than the interlocking source alarm device 1 that has received the inspection request operation, It is processing. FIG. 10 is a flowchart of the interlocked inspection process.

  First, the inspection processing unit 28 monitors the presence / absence of an interlocking inspection signal from the interlocking source alarm device 1 (corresponding to “step SE-1 and“ inspection starting step ”in the claims). And when the interlocking inspection signal from the other alarm device 1 is received via the interlocking transmission / reception part 23 (step SE-1 affirmation), the inspection process part 28 waits until predetermined | prescribed delay time passes (step SE). -2, corresponding to “inspection processing step” in the claims). The reason for waiting for the elapse of the delay time is that the alarm sound from the plurality of alarm devices 1 is duplicated by performing the alarm in the alarm device 1 after the alarm in the alarm device 1 requested to be checked. This is because it is possible to output the alarm sound at different timings so that the alarm sound can be recognized even when the maintenance company is at a remote location. For this reason, it is preferable to set the predetermined delay time to a time longer than that required for the alarm in the alarm device 1 for which inspection has been requested (for example, 6 seconds or more if the time required for the alarm is 5 seconds).

  Also, after the delay time has elapsed (Yes at Step SE-2), the inspection processing unit 28 analyzes the volume of the alarm sound included in the interlocked inspection signal (Step SE-3), and performs an alarm process on the signal indicating the volume. To the unit 26. Then, when the alarm processing unit 26 receives a signal indicating a large volume (Yes at Step SE-3), the alarm processing unit 26 outputs an alarm sound from the speaker 19 at a large volume via the audio output unit 20 (Step SE-4). Corresponding to “inspection processing step” in the claims). Alternatively, when the alarm processing unit 26 receives a signal indicating a low volume (No at Step SE-3), the alarm processing unit 26 outputs an alarm sound from the speaker 19 at a high volume via the audio output unit 20 (Step SE-5). Corresponding to “inspection processing step” in the claims).

  As the alarm sound in these steps SE-4 and SE-5, for example, after a siren sound of “Woo-woo”, a voice message “Another alarm device has been activated” is output, and this is repeated twice in total. Or the arbitrary message memorize | stored in the memory | storage part 17 in the alarm message memory | storage process mentioned above can also be used. Thereby, the maintenance company can confirm that the speaker 19 is functioning normally. When the output of such an alarm sound is completed (Yes at step SE-6), the alarm device 1 returns to the normal monitoring state (step SE-7), and the interlocked inspection process ends.

  As described above, according to the alarm device 1 according to the present embodiment, since various operations other than the inspection operation can be operated using the inspection switch 5, the structure of the alarm device 1 can be reduced by omitting individual operation means. In addition to simplification, various functions can be easily executed by eliminating the need for a dedicated jig.

[III] Modifications to Embodiments Each embodiment of the present invention has been described above, but the specific configuration and method of the present invention are within the scope of the technical idea of each invention described in the claims. Modifications and improvements can be made arbitrarily. Hereinafter, such a modification will be described.

(About problems to be solved and effects of the invention)
First, the problems to be solved by the invention and the effects of the invention are not limited to the above-described contents, and the present invention solves the problems not described above or has the effects not described above. There are also cases where only some of the described problems are solved or only some of the described effects are achieved.

(About control)
Further, all or any part of the control described as being automatically performed in each of the above embodiments may be performed manually, and conversely, all or any of the control described as being performed manually is performed. The part may be automated based on a known technique or the idea described above. In addition, the control unit 24 and each processing block in the control unit 24 shown in each embodiment can actually be configured as a CPU and a computer program that is read and executed by the CPU. It can be configured with wired logic. Further, each of the electrical components described above is functionally conceptual and does not necessarily need to be physically configured as illustrated. In other words, the specific form of distribution / integration of each unit is not limited to the one shown in the figure, and all or a part thereof may be functionally or physically distributed / integrated in arbitrary units according to various loads or usage conditions. Can be configured. In addition, the processing procedure, control procedure, specific name, and information including various data and parameters (especially information specified in each table) shown in the above documents and drawings are optional unless otherwise specified. Can be changed.

(About the program)
The various processing methods described in the above embodiment (alarm message storage processing, alarm processing, interlocked alarm processing, inspection processing, interlocked inspection processing, etc.) are based on a program prepared in advance as the alarm device 1. This can be realized by executing on a computer. This program can be distributed via a network such as the Internet. This program is recorded on a computer-readable recording medium such as a hard disk, floppy (R) disk (FD), CD-ROM, MO, DVD, etc., and read from the recording medium by the computer as the alarm device 1. Can also be executed.

(About alarm)
In the above embodiment, the case where the present invention is applied to the wall-mounted alarm device 1 has been described. However, the present invention is not limited to this, and the ceiling-mounted alarm device other than the wall-mounted alarm device is also used. The present invention can be similarly applied. In the above-described embodiment, the case where the present invention is applied to the composite type alarm device 1 that detects abnormalities such as fire, gas leakage, and incomplete combustion has been described. However, the present invention is not limited to this. Instead, the present invention can be similarly applied to an alarm device that detects only a fire or an alarm device that detects only gas. Moreover, in addition to the structure which connects the alarm device 1 to the other alarm device 1, it is good also as a structure which can be connected also to an intercom or a housing information board. Furthermore, when an abnormality is detected, radio waves may be output from the alarm device 1, the intercom, or the house information panel to notify the mobile phone. In this case, for example, the mobile phone that has received the notification vibrates by its vibration function, so that it is possible to effectively notify abnormality detection to a hearing impaired person.

  Moreover, in the said Example, although each alarm device 1A-1D is connected so that communication is mutually possible by the interlocking lead wire 2, you may communicate by radio | wireless, without using the interlocking lead wire. In this case, a unique address is assigned to each of the alarm devices 1A to 1D, and this address can be set using a dip switch, EEPROM, IC tag, or the like. In addition, either the alarm device 1 that operates with an AC power source or the alarm device 1 that operates with a battery can be appropriately selected and installed according to the environment of the installation location or the like. In this case, the alarm device 1 that operates on a battery may intermittently perform its own operation check and output the result, and in this case, the battery consumption can be suppressed. In addition, information indicating the result of its own operation check can be stored in an IC tag or the like built in the alarm device 1. Then, in the alarm device 1 that receives power supply from a receiver at a predetermined timing by wire or wirelessly, information indicating the result of the self-operation check stored in the IC tag or the like is sent back to the receiver at the time of power supply. Anyway.

(About inspection starting means)
Moreover, in the said Example, although the inspection starting means was demonstrated as the inspection switch 5 provided with the string, other various structures can be taken. For example, you may comprise as a remote control which performs infrared communication between the push button provided in the housing | casing 3, or the alarm device 1. FIG.

(About inspection processing means)
Further, in the above embodiment, the inspection processing means is the number of times the inspection switch 5 is pulled (for example, when it is pulled three times or more), the operation time (for example, when it is pulled for 0.5 seconds or more), or the operation timing. The inspection operation and other operations are activated according to (when pulled during the alarm), but other activations can be performed according to various operation methods. For example, when the inspection activation means is constituted by a plurality of switches, different processing may be performed according to the operated switch (that is, the operation location of the inspection activation means). Or you may make it perform a different process according to the length (operation stroke) by which the inspection switch 5 was pulled out. Further, the processing may be performed by detecting the tensile strength or time of the inspection switch by a pressure sensitive element using a piezoelectric element or the like.

  Moreover, in the said Example, although the inspection process means has performed the process which switches the sound volume of an alarm sound in either two steps of a high sound volume and a low sound volume, you may switch a sound volume by a still more level. Further, the output amount of any output other than the alarm sound can be changed by the inspection processing means. For example, when the fire alarm lamp 10, the gas alarm lamp 11, the incomplete combustion alarm lamp 12, or the power lamp 13 blinks or lights, these light amounts may be changed. Further, a xenon lamp or a liquid crystal panel may be used as the display output means.

  Moreover, in the said Example, although the inspection process means delays to the alarm sound output of the interlocking origin alarm device 1, and performs the process which outputs the alarm sound of the interlocking destination alarm device 1, other than an alarm sound The output timing of any output can be changed. For example, during interlock inspection, not only the interlock source but also the fire alarm lamp 10, the gas alarm lamp 11, the incomplete combustion alarm lamp 12, or the power lamp 13 of the interlock target alarm device 1 blinks or lights up. By performing the fire alarm lamp 10, the gas alarm lamp 11, the incomplete combustion alarm lamp 12, or the power lamp 13 of the previous alarm device 1 by delaying the blinking or lighting operation of the interlock source, After confirming the flashing or lighting of the original alarm device 1, it is possible to move to the mounting position of the interlocking alarm device 1 and continue to check the flashing or lighting of the alarm device 1. Alternatively, as such output timing, after the output of the interlocking destination is performed, the output of the interlocking source may be performed. Further, the output of the interlocking destination may be started before the output of the interlocking source is completely completed.

(About voice recognition processing)
In addition, the alarm device 1 can be added with a function of recognizing the voice of the user and returning a voice message according to the contents thereof. Specifically, the control unit 24 of the alarm device 1 is provided with a voice recognition unit as voice recognition processing means for recognizing the user's voice, and the storage unit 17 has a plurality of voice message information, voice message information, and a user. The table which shows matching with the audio | voice of is stored. Then, the voice recognition unit monitors the presence or absence of voice input by the user. When the user calls the alarm device 1, the voice recognition unit acquires and analyzes the voice via the microphone 21 and the voice input unit 22. Based on the analysis result, the table of the storage unit 17 is referred to, voice message information corresponding to the user's voice is selected, and the voice message information is output via the voice output unit 20 and the speaker 19.

  For example, when the user says “Good morning” to the alarm device 1, the alarm device 1 outputs “Good morning”. Or you may make it output the audio | voice of the content unrelated to a user's audio | voice. For example, when the user says “Good morning” to the alarm device 1, a bird's tweet is output. When such a function is added, a healing effect that heals the user by the output of the alarm device 1 can be exhibited, and an inspection effect that can confirm that the alarm device 1 is operating normally can be obtained.

(Calendar processing)
The alarm device 1 may be provided with a function of outputting various messages based on the calendar. For example, a timer is provided as a timer for outputting date information, and the controller 24 is provided with a calendar processor as a calendar processor for performing a message output process based on the calendar. Further, the storage unit 17 stores voice message information desired to be output on a specific day and a table indicating correspondence between the voice message information and the date. The calendar processing unit acquires date / time information from the time measuring unit at a predetermined timing, for example, every 24 hours, and refers to the table based on the date. When there is voice message information corresponding to the date, the calendar processing unit outputs the voice message information via the voice output unit 20 and the speaker 19.

  For example, on disaster prevention day, “Today is disaster prevention day. Be more careful than usual at the source of fire so that you can continue a comfortable and safe life.” Alternatively, the voice message information corresponding to the user's birthday is stored in the storage unit 17 and, on this birthday, “Mr. XXX, today is a birthday. Congratulations” is output. When such a function is added, the alarm device 1 can be used as a source of calendar information at home. In addition, a radio clock is built in the alarm device 1, the alarm device 1 is built in the radio clock, or the alarm device 1 and the radio clock are connected, and the clock information of the radio clock is used. Voice message output control may be performed. Further, in the alarm device 1 having an expiration date (lifetime), an alarm may be given by detecting that the expiration date has been reached.

  As described above, the alarm device 1 according to the present invention is useful for checking the normality of the function of each unit and executing other various operations, and in particular, easily performs these inspection operations and other operations. It is suitable for easy execution with a simple structure.
