Description

  The present invention relates to an alarm device.

  2. Description of the Related Art Conventionally, an alarm device that is installed in a monitoring area such as an office or a general house and detects an abnormality such as a fire or a gas leak is known. In this type of alarm device, for example, it is installed in a kitchen, living room, bedroom, etc. of a general house and operated alone, or alarm devices installed in each room are connected to each other and interlocked. ing. In the case of this interlocking type alarm device, for example, when the alarm device is activated in the kitchen, the alarm signal of this alarm device is sent to the alarm device in the bedroom on the second floor, and the alarm device in the bedroom is operated in conjunction, It is possible to construct a system for knowing fires in the kitchen, gas leaks, etc.

  Such an alarm device is provided with a test function for testing (inspecting) the function of the alarm device at the time of installation in the monitoring area or during the subsequent use period. For example, when the switch is operated or when the timer set time arrives, the detection means, the detection processing means, and the notification means are operated on a trial basis, and an alarm sound or the like is notified from the notification means based on the result of the test. An alarm device with a test function that generates sound has been proposed (see, for example, Patent Document 1).

JP 2010-108516 A

  However, in the conventional alarm device as described above, there is no difference in the content of notification generated from the notification means when the switch is operated (manual test) and when the timer set time arrives (automatic test). . For this reason, for example, when a switch is operated, a loud sound similar to that when the timer set time has arrived is output even though the user is in proximity to the alarm device in order to operate the switch. I was letting. Alternatively, when the timer set time arrives, a notification sound is output even when there is no abnormality in the alarm device. That is, even when the need for outputting the notification sound is low, a large volume of the notification sound is output, so there is room for reduction of current consumption and improvement of usability in the alarm test.

  This invention is made in view of the above, Comprising: It aims at providing the alarm device which reduced the current consumption which concerns on test implementation, and improved the usability.

  In order to solve the above-described problems and achieve the object, the alarm device according to claim 1 is an alarm device that outputs an alarm by detecting an abnormality in the monitoring area, and outputs an alarm sound. Means, a test instruction input reception processing means for receiving a test instruction input from an operator, and a test instruction input received through the test instruction input reception processing means, or when a predetermined test timing is reached. The test is performed on the alarm device, and the notification of the test result is performed at the time of the test based on the test instruction received through the test instruction input reception processing means and at the time of the test based on the predetermined test timing. And control means for performing different control on the notification sound output means.

  The alarm device according to claim 2 is the alarm device according to claim 1, wherein the control means performs a test based on a test instruction in which a test for the alarm device is received through the test instruction input reception processing means. Alternatively, the notification sound output means is controlled based on which of the tests based on the predetermined test timing and the combination of the test results.

  The alarm device according to claim 3 is the alarm device according to claim 1 or 2, wherein the control means performs the predetermined operation during a test based on a test instruction received via the test instruction input reception processing means. The test result is output with a notification sound having a lower volume than at the time of the test based on the test timing.

  The alarm device according to claim 4 is the alarm device according to claim 1 or 2, wherein the control means is provided in the alarm device in a test based on a test instruction received via the test instruction input reception processing means. When there is no abnormality, a notification sound is output, and when there is no abnormality in the alarm device in the test based on the predetermined test timing, a notification sound about the test result is not output.

  An alarm device according to a fifth aspect of the present invention is the alarm device according to any one of the first to fourth aspects, further comprising display means for performing display notification such as an alarm, and the control means includes the predetermined test timing and If there is an abnormality in the alarm device in the test based on that, the display means informs at least that effect, holds the display notification until a predetermined release condition is satisfied, and When there is an abnormality in the alarm device in the test based on the test instruction received via the input reception processing means, the display means does not perform display notification or causes the display notification to indicate a result abnormality. The display notification is not held.

  According to the alarm device of claim 1, for example, a notification sound is generated between a test based on a test instruction received from an operator such as a user via a switch and a test based on a predetermined test timing. Since different control is performed on the output means, the test result can be notified with an appropriate notification sound output corresponding to the property for each test, and the current consumption in the test can be reduced and the usability can be improved.

  According to the alarm device of claim 2, the test for the alarm device is either a test based on a test instruction received from an operator such as a user via a switch or a test based on a predetermined test timing. Because the control for the notification sound output means is performed based on the combination of the test result and the test result, it is possible to output the appropriate notification sound according to the property for each combination of the test start condition and the test result. Test result notification can be performed, and current consumption can be reduced and usability can be improved in the test.

  According to the alarm device of the third aspect, for example, at the time of a test based on a test instruction received from an operator such as a user via a switch, a notification is made with a lower volume than at the time of the test based on a predetermined test timing. Since the sound is output, the notification sound indicating the test result can be output at a volume that is not harsh to the operator such as the user who operates the switch, and reduction of current consumption and improvement of usability can be realized in the test.

  According to the alarm device of claim 4, for example, when there is no abnormality in the alarm device in a test based on a test instruction received from an operator such as a user via a switch, a notification sound is output about the test result, When there is no abnormality in the alarm device in the test based on the predetermined test timing, the notification sound is not output for the test result. Can be prevented from being surprised or bothered unnecessarily, and current consumption in the test can be reduced.

  According to the alarm device of claim 5, when there is an abnormality in the alarm device in the test based on the predetermined test timing, the display means displays that the test result has at least an abnormality. Since the display means keeps the display notification until a predetermined release condition is satisfied, even if the user does not notice that the notification sound indicating the test result abnormality is output, it is displayed after the fact. By confirming the notification, the user can recognize that an abnormality has occurred in the alarm device. In addition, for example, when there is an abnormality in the alarm device in a test based on a test instruction received via a switch, the display unit notifies the display, but on the other hand, the display notification is not held, so the user who operates the switch It is possible to suppress wasteful current consumption when there is a high possibility that the operator or the like can immediately recognize the display notification.

For example, a residential fire alarm device, a gas leak alarm device, a crime prevention device installed in a kitchen, stairs, bedroom, living room, etc. The present invention can be applied to various alarm devices such as sensors that detect an abnormality in a monitoring area and output an alarm.

  One of the characteristics of the alarm device according to each embodiment is that, roughly, when a test instruction (test instruction input) is received via an input means such as a switch provided in the alarm device, When the test timing is reached, a test is performed on the alarm device, and the test result is notified based on the test instruction received via the switch and the test based on the predetermined test timing. Thus, different control is performed on the notification sound output means such as a speaker.

  As a result, the test result notification can be performed with an appropriate notification sound output corresponding to the property for each test, and the current consumption in the test can be reduced and the usability can be improved.

[II] Specific Contents of Each Embodiment Next, specific contents of each embodiment according to the present invention will be described.

[Embodiment 1]
First, the first embodiment will be described. The first embodiment is a mode in which a notification sound indicating a test result is output at a smaller volume than in a test based on the fact that a predetermined test timing has been reached during a test based on a test instruction received via a switch.

(Constitution)
First, the configuration of the alarm device according to Embodiment 1 will be described. FIG. 1 is a block diagram showing an electrical main configuration of the alarm device according to the first embodiment. As shown in FIG. 1, the alarm device 1 includes an observation unit 10, a display unit 20, a speaker 30, a switch 40, a battery 50, a control unit 60, and a storage unit 70. In the present embodiment, an alarm device that observes fire smoke and detects the presence or absence of a fire is taken as an example.

(Configuration-observation part)
The observation unit 10 observes (monitors) a detection target (physical phenomenon or the like caused by abnormality) caused by abnormality in the monitoring region, and is referred to as a signal (observation signal or monitor signal) according to the observation value. It is an observation means which outputs to the control part 60. The observation unit 10 performs an observation operation in a predetermined cycle in synchronization with a clock signal supplied from, for example, a clock oscillation circuit (not shown), and inputs a signal corresponding to the observation value to the control unit 60. As this observation unit 10, for example, a smoke sensor for observing smoke generated due to a fire in a monitoring area, a temperature sensor for observing a temperature rise caused by a fire, or a flame for observing an electromagnetic wave generated by a flame caused by a fire Known observation means such as a sensor and a gas sensor for observing an increase in gas concentration caused by gas leakage can be used. Based on the observation signal from the observation means (observation unit 10), the presence or absence of abnormality is detected by the detection processing unit 61 described later. That is, the observation unit 10 and the detection processing unit 61 together constitute an abnormality detection unit.

(Configuration-display section)
The display unit 20 is a display unit (including a display unit driving circuit not shown) for performing display notification such as an alarm based on the control of the control unit 60. For example, an LED (Light Emitting Diode), a 7-segment display, a liquid crystal Display means using a known display device such as a display can be used.

(Configuration-Speaker)
The speaker 30 is notification sound output means (including a speaker drive circuit and a volume control circuit not shown) that outputs a notification sound such as an alarm sound based on the control of the control unit 60. The specific form of the notification sound output from the speaker 30 is arbitrary, and a buzzer sound, a synthesized voice generated as necessary, a pre-recorded voice, or the like can be output.

(Configuration-Switch)
The switch 40 is an input means, and constitutes a test instruction input acceptance processing means together with an input auxiliary circuit (not shown) and a detection processing section 61 described later. Thereby, an operation input (instruction input) to the alarm device 1 is received from an operator such as a user. As the switch 40, for example, a non-holding (non-locking) type push switch is used.

(Configuration-Battery)
The battery 50 supplies power to each component of the alarm device 1 (note that the power supply line is not shown in FIG. 1). As the battery 50, a known battery such as a lithium ion battery can be used.

(Configuration-control unit)
The control unit 60 is a control unit that controls each unit of the alarm device 1, and specifically, a CPU, various programs that are interpreted and executed on the CPU (a basic control program such as an OS, and the OS is started on the OS). And an internal memory such as a RAM for storing the program and various data.

  The control unit 60 includes a detection processing unit 61 and a test processing unit 62 in terms of functional concept. The detection processing unit 61 detects the presence or absence of an abnormality in the monitoring region based on the output (observation signal) from the observation unit 10 and constitutes an abnormality detection means together with the observation unit 10. The detection processing unit 61 detects an operation input to the switch 40, and constitutes a test instruction input reception processing means together with the switch 40 and an input auxiliary circuit (not shown). The test processing unit 62 is a test processing unit that executes the test of the alarm device 1 when a predetermined condition is satisfied and controls the speaker 30 according to the test result. Details of processing executed by each component of the control unit 60 will be described later.

(Configuration-storage unit)
The storage unit 70 is a storage unit that stores programs and various data necessary for control by the control unit 60. The storage unit 70 is configured using a rewritable recording medium, and for example, a nonvolatile recording medium such as a flash memory can be used. The recorded contents can be rewritten from the outside by the user as necessary. A ROM may be provided separately, and programs and data that do not need to be rewritten may be stored in the ROM.

(processing)
Next, the process which the alarm device 1 comprised as mentioned above performs is demonstrated.

(Processing-Monitoring processing)
First, the monitoring process will be described. FIG. 2 is a flowchart showing a schematic example of the monitoring process executed by the alarm device 1 (steps are abbreviated as “S” in the description of each process below). This monitoring process is started, for example, when the alarm device 1 is powered on. Note that the alarm switch of the present embodiment is not provided with a power switch, and the power is turned on when the battery 50 is attached to the internal circuit so as to be conductive.

  When the monitoring process is started, the test processing unit 62 determines whether or not the switch 40 is turned on (test instruction operation) (SA1). For example, it is determined that the switch 40 is turned on when a reliable pressing of the switch 40 configured as a push switch is detected by the detection processing unit 61. The case where a reliable press is detected is the case where a so-called chattering removal process, a press determination process based on, for example, a press time, etc. This is the case when it is detected as a bad input.

  As a result, when the switch 40 is not turned on (SA1, No), the test processing unit 62 determines whether or not a predetermined test timing has come (SA2). The test timing is generated inside the alarm device 1 or acquired from the outside. Whether or not the test timing has come is determined, for example, by measuring an elapsed time from the previous test using a timer (not shown) or the like and determining whether or not a predetermined time (for example, one month) has elapsed. For example, when it reaches one month or when one month or more has elapsed, it is determined that the test timing has come. Alternatively, for example, the date and time when the test should be performed may be stored in the storage unit 70 in advance, and it may be determined that the test timing has been reached when the date and time has arrived. Note that a predetermined delay time or the like may be provided after the determination that the test timing has been reached in step SA2 (SA2, Yes) and before the transition to the subsequent step (SA3 or SA5).

  If the predetermined test timing is not reached in step SA2 (SA2, No), the detection processing unit 61 executes a detection process (SA3). After the detection process is completed, the process returns to SA1, and the test processing unit 62 determines whether or not the switch 40 is turned on. The contents of the detection process will be described later.

  When the switch 40 is turned on in SA1 (SA1, Yes), the test processing unit 62 executes a test process (manual test process) based on a test instruction by manual operation (SA4), and then returns to SA1. The contents of the manual test process will be described later.

  If the predetermined test timing is reached in SA2 (SA2, Yes), the test processing unit 62 executes a test process (periodic automatic test process) based on the test timing (SA5), and then returns to SA1. . The contents of the periodic automatic test process will be described later.

(Processing-Detection processing)
Next, the detection process will be described. FIG. 3 is a flowchart showing a schematic example of detection processing.

  When the detection process is started, the detection processing unit 61 acquires an observation value from the observation unit 10 (SB1). For example, the detection processing unit 61 causes the observation unit 10 to perform a detection operation in synchronization with a clock signal supplied from a clock oscillation circuit, and acquires an observation value based on the signal output from the observation unit 10.

  Subsequently, the detection processing unit 61 determines whether or not the acquired observation value is equal to or greater than a predetermined threshold stored in the storage unit 70 (SB2).

  As a result, if the observed value is not greater than or equal to the threshold value (if it is less than the threshold value) (SB2, No), it is assumed that no abnormality has occurred in the monitoring area, and the detection processing unit 61 ends the detection process and performs the monitoring process ( Returning to FIG. 2, SA1).

  On the other hand, when the observed value is equal to or greater than the threshold value (SB2, Yes), it is assumed that an abnormality has occurred in the monitoring area, and the detection processing unit 61 outputs an alarm (SB3). For example, an alarm sound (for example, “Peep, fire is a fire.”) Is output from the speaker 30 as a notification sound that an abnormality has occurred in the monitoring area, and an abnormality has occurred in the monitoring area. Display (for example, blinking of red LED) is output from the display unit 20. When the alarm device 1 has a communication unit (not shown), the communication unit transmits an alarm signal (an interlock signal) to another alarm device 1, a disaster prevention receiver, or other interlocking device. May be.

  Thereafter, the detection processing unit 61 stands by with an alarm output until the switch 40 is turned on (SB4, No), or waits until there is an abnormality recovery in which no abnormality in the monitoring area is detected by the detection processing unit 61 ( When the switch 40 is turned on (SB4, Yes), or when it is determined that there is an abnormality recovery, the alarm output is stopped (SB5). Here, when the alarm device 1 includes a communication unit, an interlocking signal may be transmitted for alarm stop or abnormality recovery. Note that the switch ON determination is performed in the same manner as SA1 in FIG. Further, a predetermined delay time may be provided before stopping the alarm at SB5. Further, the warning sound may be stopped first, and then the display indicating that an abnormality has occurred after a predetermined time has elapsed may be stopped.

  After the alarm output is stopped, the detection processing unit 61 waits until a predetermined time (for example, 2 minutes) elapses (SB6, No). When the predetermined time elapses (SB6, Yes), the detection processing is terminated and the monitoring process is performed. Return to (FIG. 2, SA1).

(Processing-Manual test processing)
Next, the manual test process will be described. FIG. 4 is a flowchart showing a schematic example of manual test processing.

  When the manual test process is started, the test processing unit 62 sets the output volume of the notification sound output from the speaker 30 via a volume control circuit (not shown) to “small” which is smaller than the normal volume ( SC1).

  Next, the test processing unit 62 executes a test of the alarm device 1 (SC2). For example, the test processing unit 62 generates a test signal similar to the observation signal output from the observation unit 10 and inputs this test signal to the detection processing unit 61 so as to artificially determine whether there is an abnormality in the monitoring region. . Or the detection process part 61 produces | generates the state with abnormality detection internally. In a subsequent process, the detection processing unit 61 outputs an alarm from the speaker 30 or the display unit 20 in the same manner as SB3 in the detection process. Thereby, an operator such as a user can confirm that the detection processing unit 61 is functioning normally. In this case, since the volume is set to “low” in SC1, the alarm sound can be output at a volume that is not harsh to the operator or other operator who operates the switch 40. At this time, the test processing unit 62 may determine whether or not the speaker 30 and the display unit 20 operate normally. Of course, other test items such as speaker wiring disconnection test, battery voltage drop (remaining battery capacity decrease) test, various faults / failures test, communication function abnormality test, etc. will be reported. It may be.

  If there is no abnormality (failure or failure) in the alarm device 1 as a result of the test of the alarm device 1 (SC3, No), the test processing unit 62 notifies that the test result is normal, for example, “Pip normal” Is output from the speaker 30 or an appropriate display indicating that there is no abnormality in the test result is output from the display unit 20 (not shown), and then the volume of the notification sound output from the speaker 30 is set. Reset to normal volume (SC4). Thereafter, the test processing unit 62 ends the manual test processing and returns to the monitoring processing (FIG. 2, SA1).

  On the other hand, if there is any abnormality in the alarm device 1 (SC3, Yes), the test processing unit 62 generates an abnormal alarm sound (for example, “pick failure”) as a notification sound indicating that the alarm device 1 has an abnormality. Output from the speaker 30 (SC5). Also in this case, since the sound volume is set to “low” in SC1, the alarm sound can be output at a sound volume that is not harsh to the operator or the like who operates the switch 40. In this case, a display indicating that the alarm device 1 is abnormal may be displayed on the display unit 20. However, since it is highly possible that the user who operated the switch 40 can immediately recognize the display notification, the test processing unit 62 may not hold the display notification on the display unit 20. Thereby, useless current consumption can be suppressed. After the process of SC5, the control unit 60 returns to SC2. Alternatively, after the process of SC5, the manual test process may be terminated and the process may return to the monitoring process (FIG. 2, SA1). In this case, for example, the monitoring process may be restarted by resetting the control unit 60 by, for example, turning on the power of the alarm device 1 again (the same applies to the periodic automatic test process described later).

  In addition, when the alarm device 1 is provided with a communication function, a manual (interlocking) test is performed as in SC2 based on reception of the interlock signal from another alarm device. It is a test about. Here, the test results of other alarm devices are not linked and notified, but the self test is performed by interlocking with the manual test according to the operation instruction of the other alarm devices, and the self test results are reported. That is, for example, in SA1 of FIG. 2, it is determined whether or not a test interlock signal is received from another alarm device together with the determination of the self switch ON. Will be processed. In this way, if the test instruction is operated with any one alarm device, the test processing is performed in conjunction with the other alarm devices, so that the labor involved in the test can be saved.

(Processing-periodic automatic test processing)
Next, the periodic automatic test process will be described. FIG. 5 is a flowchart showing a schematic example of the periodic automatic test process.

  When the periodic automatic test process is started, the test processing unit 62 executes the test of the alarm device 1 in the same manner as the above-described manual test processes SC2, SC3, and SC5 (SD1 to SD3), for example. In this case, since the volume of the notification sound output from the speaker 30 is set to the normal volume, the user can notice even when the user is away from the alarm device 1. The notification sound can be output at the volume. At this time, the test processing unit 62 may determine whether or not the speaker 30 and the display unit 20 operate normally.

  As a result of the test of the alarm device 1, when there is no abnormality (failure or failure) in the alarm device 1 (SD2, No), the test processing unit 62 notifies that the test result is normal, for example, “Pip normal” For example, a voice message such as “is a small volume similar to that set in SC1 of FIG. 4” or an appropriate display indicating that there is no abnormality in the test result is output (not shown). The periodic automatic test process is terminated, and the process returns to the monitoring process (FIG. 2, SA1).

  On the other hand, when there is some abnormality in the alarm device 1 (SD2, Yes), the test processing unit 62 outputs an abnormality alarm sound from the speaker 30 as a notification sound indicating that the alarm device 1 has an abnormality (SD3). . Also in this case, since the sound volume is set to the normal sound volume, even when the user is away from the alarm device 1, the notification sound is output at a sound volume that the user can notice. be able to.

  Furthermore, the test processing unit 62 causes the display unit 20 to perform display notification that the alarm device 1 has an abnormality (for example, blinking three times every 10 seconds) and hold the display notification (SD4). This allows the user to recognize that an abnormality has occurred in the alarm device 1 by confirming the display notification afterwards even if the user has not noticed that an abnormal alarm sound in the test has been output. Can do.

  While the predetermined release condition is not satisfied (SD5, No), the test processing unit 62 holds the display notification on the display unit 20 (SD4). For example, a predetermined time has elapsed since the start of display notification, the switch 40 has been turned ON twice in succession, or the test of the alarm device 1 is executed in the same manner as SD1, and the alarm device 1 has an abnormality. It can be set as a predetermined release condition that it has been determined that it has been resolved. Alternatively, when the switch 40 is turned on while holding the display notification on the display unit 20, an abnormal alarm sound is output again from the speaker 30, and the output of the abnormal alarm sound is completed as a cancellation condition. Good. Thereby, after making a user recognize display notification reliably, display notification can be cancelled | released.

  When a predetermined release condition is satisfied in SD6 (SD5, Yes), the test processing unit 62 releases the display notification by the display unit 20 (SD6). Here, the timer for determining whether or not the test timing is reached is reset and restarted. Thereafter, the test processing unit 62 ends the periodic automatic test processing and returns to the monitoring processing (FIG. 2, SA1).

  Also, for example, in SA2 of FIG. 2, the presence / absence of the test timing and the presence / absence of reception of the interlocking signal based on the arrival of the test timing of another alarm device are determined. Processing similar to SA5 based on timing arrival (SD1 to SD6 in FIG. 5) may be performed. In this way, since the test timing with other alarm devices is unified, automatic testing is performed at the same time, and it is possible to prevent the test execution time zones from varying among a plurality of alarm devices.

(effect)
As described above, according to the first embodiment, the test time based on the test instruction received from the operator such as the user via the switch 40 (that is, when the manual test process is executed) and the predetermined test timing are reached. Since different control is performed on the speaker 30 for the notification of the test result at the time of the test based on the test (that is, when the periodic automatic test process is executed), the test result notification is performed with an appropriate notification sound output corresponding to the property for each test It is possible to reduce the current consumption in the test and improve usability.

  In particular, during a test based on a test instruction received from an operator such as a user via the switch 40, a notification sound is output at a lower volume than during a test based on a predetermined test timing. It is possible to output a notification sound indicating the test result at a volume that is not harsh for the user who has performed, thus realizing reduction of current consumption and improvement of usability in the test.

  Further, if there is an abnormality in the alarm device 1 in the test when the predetermined test timing is reached, the display unit 20 notifies that there is at least an abnormality as a test result and the predetermined release condition is satisfied. Therefore, even if the user does not notice that a notification sound indicating an abnormality in the test result is output, an abnormality occurs in the alarm device 1 by confirming the display notification afterwards. The user can be made aware of this. Further, when there is an abnormality in the alarm device 1 in the test based on the test instruction received via the switch 40, the display unit 20 does not hold display notification more than necessary, so that the user who operates the switch 40 immediately When there is a high possibility that the display notification can be recognized, wasteful current consumption can be suppressed.

[Embodiment 2]
Next, a second embodiment will be described. In the second embodiment, when there is no abnormality in the alarm device in a test based on a test instruction received from an operator such as a user via a switch, a notification sound is output about the test result, and a predetermined test timing is reached. When there is no abnormality in the alarm device in the test based on the above, a notification sound is not output for the test result. The configuration of the second embodiment is substantially the same as the configuration of the first embodiment, unless otherwise specified. The same configuration as that of the first embodiment is used in the first embodiment. The same reference numerals and / or names as those used are attached as necessary, and description thereof is omitted. In the second embodiment, the interlocking process in the case where the alarm device 1 has a communication function is performed by determining whether or not the interlocking signal is received in SA1 or SA2 in FIG. Based on whether or not a signal is received, the process may be shifted to the processes of FIGS. 3, 4, and 6, respectively.

(Processing-periodic automatic test processing)
A periodic automatic test process according to the second embodiment will be described. FIG. 6 is a flowchart showing a schematic example of a periodic automatic test process according to the second embodiment. Note that SE7 to SE9 of the periodic automatic test process in the second embodiment are the same as SD4 to SD6 in FIG.

  When the periodic automatic test process is started, the test processing unit 62 sets the output volume of the notification sound output from the speaker 30 via the volume control circuit (not shown) to “mute” (SE1).

  Next, for example, the test processing unit 62 executes the test of the alarm device 1 in the same manner as SD1 in FIG. 5 in the periodic automatic test processing of the first embodiment (SE2). However, since the volume is set to “mute” in SE1, no notification sound is output from the speaker 30 when there is no abnormality in the test result. That is, when there is no abnormality in the alarm device 1, no notification sound is output, so that it is possible to prevent the user and other operators from being surprised or bothered unnecessarily by outputting the notification sound even though there is no abnormality. . At this time, an operator such as a user may visually determine whether or not the display unit 20 operates normally. However, since the volume of the speaker 30 is set to “mute”, it is not determined whether or not the notification sound output function has been normally operated.

  As a result of the test of the alarm device 1, when there is no abnormality in the alarm device 1 (SE3, No), the test processing unit 62 resets the volume of the notification sound output from the speaker 30 to the normal volume (SE4). . Thereafter, the test processing unit 62 ends the periodic automatic test processing and returns to the monitoring processing (FIG. 2, SA1).

  On the other hand, when there is some abnormality in the alarm device 1 (SE3, Yes), the test processing unit 62 resets the volume of the notification sound output from the speaker 30 to the normal volume (SE5). An abnormal alarm sound is output from the speaker 30 as a notification sound indicating that there is an abnormality (SE6). In this case, since the volume is set to the normal volume in SE5, even when the user is away from the alarm device 1, the notification sound is output at a volume that the user can notice. Can be made.

(effect)
As described above, according to the second embodiment, either the test based on the test instruction received from the operator such as the user via the switch 40 or the test based on the predetermined test timing being used as the test for the alarm device 1. Is controlled based on the combination of the test result and the test result, the test result is output with an appropriate notification sound output according to the property for each combination of the test start condition and the test result. Notification can be performed, and current consumption can be reduced and usability can be improved in the test.

  In particular, when there is no abnormality in the alarm device 1 in a test based on a test instruction received from an operator such as a user via the switch 40, a notification sound is output about the test result, and a predetermined test timing is reached. If there is no abnormality in the alarm device 1 in the test based on the test result, the alarm sound is not output for the test result. Can be prevented, and current consumption in the test can be reduced.

[Embodiment 3]
Finally, Embodiment 3 will be described. The third embodiment is a mode for confirming whether there is an abnormality in the alarm device in the detection process. The configuration of the third embodiment is substantially the same as the configuration of the first embodiment unless otherwise specified, and the same configuration as that of the first embodiment is used in the first embodiment. The same reference numerals and / or names as those used are attached as necessary, and description thereof is omitted.

(Constitution)
First, the configuration of the alarm device 1 according to Embodiment 3 will be described. In addition, since each structure of the alarm device 1 is the same as that of Embodiment 1 except the information memorize | stored in the memory | storage part 70, illustration of a block diagram is abbreviate | omitted.

(Configuration-storage unit)
The storage unit 70 according to the third embodiment stores an observation unit abnormality flag for identifying whether or not the observation unit 10 is abnormal, and a battery abnormality flag for identifying whether or not the battery 50 is abnormal. When these flags are “ON”, there is an abnormality. It is assumed that “OFF” indicating that there is no abnormality is stored in the storage unit 70 as initial values of the observation unit abnormality flag and the battery abnormality flag.

(Processing-Detection processing)
Next, the detection process will be described. FIG. 7 is a flowchart showing a schematic example of the detection process according to the third embodiment. Note that SF1 to SF6 in the detection process in the third embodiment are the same as SB1 to SB6 in FIG.

  When the observation value is not equal to or greater than the threshold value in SF2 (if it is less than the threshold value) (SF2, No), the detection processing unit 61 determines whether there is an abnormality (failure or failure) in the observation unit 10 (SF7). For example, the observation unit 10 irradiates detection light from a light emitting element into a smoke detection space provided in the alarm device 1 and detects detection light (scattered light and scattered light from smoke particles flowing into the smoke detection space from a monitoring region). Is received by a light receiving element and converted into an electrical signal, and an electrical signal having a voltage corresponding to the smoke density is output. Even if there is no smoke in the smoke detection space, a predetermined voltage is set. The electrical signal (referred to as zero point signal) is set to be output. In this case, when the electrical signal output from the observation unit 10 falls below the zero point signal level by a predetermined value or more, the detection processing unit 61 determines that some abnormality such as a disconnection has occurred in the observation unit 10.

  As a result of SF7, when it is determined that the observation unit 10 has an abnormality (for example, an observation unit failure) (SF7, Yes), the detection processing unit 61 has an abnormality in the observation unit abnormality flag stored in the storage unit 70. "ON" indicating that this is done (SF8).

  When it is determined that there is no abnormality in the observation unit 10 in SF7 (SF7, No), or after the processing of SF8, the detection processing unit 61 determines whether it is time to check the output voltage value of the battery 50. (SF9). For example, the elapsed time since the last check of the output voltage value of the battery 50 is measured by a timer (not shown), and the timing for checking the output voltage value when a predetermined time (for example, 4 hours) elapses is obtained. It is determined that (timing has arrived).

  As a result, when the timing is not reached (SF9, No), the detection processing unit 61 ends the detection process and returns to the monitoring process (FIG. 2, SA1).

  On the other hand, when it is time to check the output voltage value of the battery 50 (SF9, Yes), the detection processing unit 61 determines whether the output voltage value of the battery 50 observed through a voltage detection circuit (not shown) is less than the threshold value. Is determined (SF10).

  As a result, when the output voltage value of the battery 50 is not less than the threshold value (when it is equal to or greater than the threshold value) (SF10, No), the detection processing unit 61 ends the detection process and returns to the monitoring process (FIG. 2, SA1).

  On the other hand, when the output voltage value of the battery 50 is less than the threshold value (SF10, Yes), the detection processing unit 61 sets the battery abnormality flag stored in the storage unit 70 to “ON” indicating that there is an abnormality ( SF11). Thereafter, the detection processing unit 61 ends the detection process and returns to the monitoring process (FIG. 2, SA1).

(Processing-Manual test processing)
Next, the manual test process will be described. FIG. 8 is a flowchart showing a schematic example of manual test processing according to the third embodiment. Note that SG1 of the manual test process in the third embodiment is the same as SC1 in FIG. 4 and SG4 described in the first embodiment, and SG4 is the same as SC4.

  After the process of SG1, the test processing unit 62 determines whether or not the alarm device 1 has an abnormality such as a failure or a failure in the detection process (SG2). Specifically, the test processing unit 62 refers to the observation unit abnormality flag and the battery abnormality flag stored in the storage unit 70, and if at least one of these flags is “ON”, the test unit 62 It is determined that there is an abnormality.

  As a result, when there is no abnormality in the alarm device 1 in the detection process (SG2, No), the test processing unit 62 indicates that there is no abnormality in the alarm device 1, and the alarm device 1 is connected from the speaker 30 or the display unit 20. A notification of normality is output (SG3).

  On the other hand, when there is an abnormality in the alarm device 1 in the detection process (SG2, Yes), the test processing unit 62 outputs an abnormality alarm sound from the speaker 30 as a notification sound indicating that the alarm device 1 is abnormal (SG5). ). At this time, an abnormal alarm sound corresponding to the generated abnormality may be output from the speaker 30 based on the observation unit abnormality flag and the battery abnormality flag referred to in SG2. That is, when an abnormality occurs in the observation unit 10, for example, when an abnormal alarm sound is output from the speaker 30 by a voice message “pick failure”, and the output voltage value of the battery 50 becomes less than the threshold value. For example, an abnormal alarm sound by a voice message “Battery exhausted” may be output from the speaker 30. After the process of SG5, the test processing unit 62 ends the manual test process and returns to the monitoring process (FIG. 2, SA1).

(Processing-periodic automatic test processing)
Next, the periodic automatic test process will be described. FIG. 9 is a flowchart showing a schematic example of a periodic automatic test process according to the third embodiment. Since SH4 to SH6 of the periodic automatic test process in the third embodiment are the same as SD4 to SD6 in FIG. 5 described in the first embodiment, description thereof is omitted.

  When the periodic automatic test process is started, the test processing unit 62 determines whether or not the alarm device 1 has an abnormality such as a failure or a failure in the detection process (SH1). Specifically, the test processing unit 62 refers to the observation unit abnormality flag and the battery abnormality flag stored in the storage unit 70, and if at least one of these flags is “ON”, the test unit 62 It is determined that there is an abnormality.

  As a result, when there is no abnormality in the alarm device 1 in the detection process (SH1, No), the test processing unit 62 indicates that there is no abnormality in the alarm device 1, and the alarm device 1 is connected from the speaker 30 or the display unit 20. A notification of normality is output (SH2). Thereafter, the test processing unit 62 ends the periodic automatic test processing and returns to the monitoring processing (FIG. 2, SA1).

  On the other hand, when there is an abnormality in the alarm device 1 in the detection process (SH1, Yes), the test processing unit 62 outputs an abnormality alarm sound from the speaker 30 as a notification sound indicating that the alarm device 1 is abnormal (SH3). ). In this case, similarly to the manual test process of FIG. 8, an abnormal alarm sound corresponding to the generated abnormality may be output from the speaker 30 based on the observation unit abnormality flag and the battery abnormality flag referred to in SH1.

(effect)
As described above, according to the third embodiment, when a test instruction is received via the switch 40 or when a predetermined test timing is reached, whether or not there is an abnormality such as a failure or failure in the alarm device 1 detected in advance. Since the corresponding alarm is output, in addition to the same effect as in the first embodiment, the test instruction is given via the switch 40, so that the user can detect the abnormality of the alarm device 1 detected in advance at a desired timing. Can be confirmed. Even when the user does not give a test instruction, the abnormality of the alarm device 1 detected in advance can be notified when the predetermined test timing is reached.

[III] Modifications to Each Embodiment While each embodiment according to the present invention has been described above, the specific configuration and means of the present invention are the same as the technical idea of each invention described in the claims. Modifications and improvements can be arbitrarily made within the range. 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 manual test processing)
In the above-described third embodiment, when the manual test process of FIG. 8 is started, the test processing unit 62 first sets the volume of the notification sound output from the speaker 30 to “small” which is smaller than the normal volume. Although described as (SG1), the volume may be set to “low” at another timing. For example, the volume may be set to “low” at the timing before the alarm is output from the speaker 30 at SG3 or before the abnormal alarm sound is output from the speaker 30 at SG5.

(Regular automatic test processing)
In each of the above-described embodiments, it has been described that in the periodic automatic test process, an abnormal alarm sound is output from the speaker 30 as a notification sound indicating that the alarm device 1 is abnormal. In this case, the volume of the abnormal alarm sound is You may control the speaker 30 so that may rise in steps. Thereby, it is possible to prevent the user from being surprised or bothered by suddenly outputting a high volume abnormal alarm sound. For example, the periodic automatic test may be replaced with an irregular automatic test.
