Description

  The present invention relates to an alarm device, and more particularly to an alarm device that outputs a voice message.

  Conventionally, an alarm device that outputs a voice message is known (see, for example, Patent Document 1).

  The above-mentioned patent document 1 discloses an alarm device which outputs a notification sound of "We will perform automatic inspection of the alarm sound from now on" when performing automatic periodic inspection. The alarm device of the above-mentioned patent document 1 outputs the above-mentioned notification sound when the period of the regular inspection of 30 days has passed after the power is turned on, and then the alarm device becomes normal by outputting a voice alarm outputted at the time of alarm. It is configured to perform an operation of periodic inspection as to whether or not alarm output can be performed.

Patent No. 5234657 gazette

  However, the alarm described in Patent Document 1 only outputs a notification sound to that effect when starting the periodic inspection, and can notify the user of the operation of the alarm other than the alarm in a situation other than the periodic inspection. It is not a thing.

  When the alarm device performs an operation necessary for the function other than the alarm, generally, the alarm sound is not output, and the alarm lamp is in operation by lighting or blinking the alarm lamp provided in the alarm device. To notify. However, the situation in which the lamp of the alarm blinks other than the alarm may cause some users to suspect that the alarm may be broken. In such a case, in particular, the user's attention tends to be directed to the alarm, and it is desirable that the user can appropriately grasp the state of the alarm at the time of power-on.

  In particular, in the case of a gas alarm for general household use, it is not likely that the user grasps the specification of the alarm from the instruction manual etc. Therefore, the alarm can be appropriately operated without bothering the user. It is important for the user to be able to properly grasp the state of the alarm.

  The present invention has been made to solve the problems as described above, and one object of the present invention is to enable a user to appropriately grasp the state of the alarm when power is turned on. It is to provide an alarm.

An alarm according to one aspect of the present invention includes an alarm body including a detection unit for detecting an abnormality and a notification unit having a speaker for outputting an alarm sound, and the alarm body when the power of the alarm body is turned on. While performing control to execute the initial operation, after the power of the alarm main body is turned on and after the start of the initial operation , the first voice message notifying that the initial operation is performed is output to the notification unit And a control unit that performs control.

  In the present specification, “the first voice message related to the implementation of the initial operation” indirectly implies performing the initial operation as well as a message directly notifying the implementation of the initial operation. It is a broad concept that includes messages to be notified and messages that notify of some information related to the initial operation. In addition, "voice message" is to inform the user of the notification sound to the user by pronouncing the language, and "notification sound" notifies the user of not only voice message but also buzzer sound etc. Generally refers to the sound that is output to

The alarm according to an aspect of the present invention, by the above configuration, when carrying out the initial operation at power-on, after power-on of the alarm device main body, and, after starting the implementation of the initial operation, carried out initial operations The first voice message is output to notify that the user is able to at least know that the alarm is in the initial operation. Therefore, for example, unlike in the case of informing the state of the alarm by flickering the lamp without any voice output during the initial operation, for example, the first voice message indicates that the alarm performs the necessary operation properly. I can understand. This enables the user to appropriately grasp the state of the alarm when the power is turned on.

  Preferably, in the alarm according to the above aspect, the notification unit further includes a lamp for giving notification by lighting or blinking, and the control unit causes notification by the lamp for a first time after the power is turned on, and A control is performed to output a first voice message when a second time shorter than a first time elapses after the power is turned on. According to this structure, the user can be notified of the first voice message to the user after the second time has elapsed after the start of notification by the lamp in the initial operation. That is, if a voice message is immediately output immediately after the power is turned on, the user may be surprised. However, the first voice message can be transmitted after the user has been alerted by the lamp. As a result, it is possible to make the user understand the state of the alarm device at the time of power on without performing an unexpected operation of the user.

  In the alarm according to the above aspect, preferably, the initial operation includes an inspection operation of the alarm main body, and the control unit causes the notification unit to output a second voice message indicating the inspection result, and the inspection result is normal. If there is, control is performed to further output a third voice message indicating that the detection unit performs a monitoring operation. According to this configuration, not only notification of the inspection result but also notification that the alarm device performs monitoring operation can be notified by the third voice message. That is, after outputting the first voice message when the power is turned on, only by notifying the inspection result (the second voice message), the user grasps whether or not any operation is necessary to cause the alarm device to perform the monitoring operation. I can not do it. Therefore, by outputting the third voice message when the inspection result is normal, it is possible to make the user understand that the alarm device has started the normal monitoring operation, so the state of the alarm device can be more appropriately Can be made known to the user.

  In this case, preferably, the alarm body further includes an operation unit that receives an operation input, and the control unit performs an inspection operation of the alarm body according to the input to the operation unit after the initial operation ends, The same voice message output control as the inspection operation in the operation is performed. According to this configuration, in addition to the initial operation, the second voice message similar to the initial operation and the third voice message (in the normal case) are output also when the user voluntarily performs the check operation. can do. By outputting the same voice message as the inspection in the initial operation, the user can grasp the state of the alarm without misunderstanding. In addition, since it is possible to suppress the unnecessary increase of the voice message pattern, it is possible to suppress the increase in the storage capacity of the voice message in the alarm device.

  In the configuration that performs the inspection operation, preferably, when performing the inspection operation, the control unit performs control to output a fourth voice message regarding the remaining period of the expiration date of the alarm main body. Here, for example, in Japan, with regard to gas alarms for general household use, an expiration date of 5 years is defined, and alarms whose expiration date has passed are replaced. Therefore, if configured as described above, the user can grasp the remaining period up to the replacement time of the alarm by the fourth voice message output when the inspection operation is performed, so that the alarm regarding the expiration date It is possible to make the user appropriately grasp the state of the device.

  According to the present invention, as described above, it is possible for the user to appropriately grasp the state of the alarm when power is turned on.

  Hereinafter, embodiments of the present invention will be described based on the drawings.

  First, with reference to FIG. 1 and FIG. 2, the structure of the alarm device 100 by one Embodiment is demonstrated.

(Whole configuration of alarm)
The alarm device 100 illustrated in FIG. 1 is a gas alarm device that notifies a user of a gas leak. Alarm device 100 is installed, for example, indoors, and detects a detection target gas present in the installation environment. The alarm device 100 can report, for example, a gas leak of a fuel gas, which is a city gas or an LP gas. The alarm device 100 can report, for example, a gas leak of carbon monoxide gas (CO gas). The alarm device 100 is, for example, a household gas alarm device, but may be configured as a business use or a combination of a home use and a business use. The alarm 100 shown in FIG. 1 shows an example of a wall-mounted type alarm attached to an indoor wall. The alarm 100 may be a ceiling-mounted type that is mounted on an indoor ceiling.

  The alarm device 100 includes a detection unit 1, a notification unit 2, an operation unit 3, and a control unit 4 (see FIG. 2). In the example of FIG. 1 and FIG. 2, the alarm device 100 is equipped with the alarm main body 10 in which the detection part 1, the alerting | reporting part 2, the operation part 3, and the control part 4 were integrated in the housing | casing.

  The detection unit 1 performs abnormality detection in the installation environment. Specifically, the detection unit 1 is configured to detect at least one of gas and fire. Gas and fire anomaly detection is to detect gas leaks and heat (temperature) or smoke generated with a fire. The detection unit 1 may further detect other than gas and fire as detection targets.

  In the example shown in FIG. 2, the detection unit 1 is configured to detect a fuel gas (city gas or LP gas) and a carbon monoxide gas. Specifically, the detection unit 1 includes a gas sensor 11 (see FIG. 2) that detects a fuel gas (city gas or LP gas) and a CO sensor 12 (see FIG. 2) that detects a CO gas. The structure and detection principle of the sensor are not particularly limited. As an example, the gas sensor 11 and the CO sensor 12 are configured by semiconductor type gas detection elements, and specifically, may be configured by heat ray type semiconductor type gas sensors. The hot-wire semiconductor gas sensor detects the concentration of the gas to be detected by utilizing the change in electrical conductivity when the gas to be detected is adsorbed on the surface of the element heated to a predetermined temperature (several hundred degrees C.) by the supply of current. Is configured. The gas sensor 11 detects methane contained in a fuel gas as a detection target gas. The CO sensor 12 detects CO gas generated due to incomplete combustion or the like as a detection target gas. The alarm main body 10 is formed with an opening 10a (see FIG. 1) for contacting the surrounding gas to the detection unit 1 in the housing.

  The notification unit 2 is configured to at least notify by a notification sound. That is, the notification unit 2 includes the speaker 21 that outputs a notification sound. In the present embodiment, the notification unit 2 includes, in addition to the speaker 21, a lamp 22 that performs notification by lighting or blinking. Further, the notification unit 2 has a signal output unit 23 that externally outputs a notification signal.

  The speaker 21 is controlled by the control unit 4 to output a predetermined notification sound. The speaker 21 is controlled by the control unit 4 to output a predetermined voice message. The alarm main body 10 has an opening 10 b (see FIG. 1) for diffusing the sound of the speaker 21 to the outside.

  The lamp 22 is configured to generate light of a predetermined color under the control of the control unit 4. The lamp 22 is configured of, for example, an LED light source. Although one or more lamps 22 are provided, in the example of FIG. 1, the alarm main body 10 is provided with three lamps 22. The three lamps 22 generate light of different colors (for example, red, yellow, green). As an example, the red lamp 22 reports on fuel gas (gas sensor 11), the yellow lamp 22 reports on CO gas (CO sensor 12), the green lamp 22 is a power supply other than the detection gas, A notification regarding failure, other operations of the alarm device 100, and the like is performed. The signal output unit 23 is configured by an interface unit (output terminal) for externally outputting a notification as an external output signal when the alarm device 100 is connected to an external device (another safety device).

  The operation unit 3 is configured to receive an operation input to the alarm device 100. The structure of the operation unit 3 is not particularly limited, and may be various switches such as a push button type, a lever type, and a rotary type, a touch sensor, and the like. In FIG. 1, the operation unit 3 is configured by a push button type switch provided on the alarm main body 10. The alarm main body 10 is provided with one operation unit 3. The operation unit 3 receives an input operation (press operation) and outputs an input signal to the control unit 4. The alarm main body 10 may include a plurality of operation units 3.

  As shown in FIG. 2, the control unit 4 performs control processing of each unit provided in the alarm device 100. The control unit 4 is configured to include a processor (arithmetic processing unit) such as a CPU or a microcomputer. The control unit 4 acquires the signal of each sensor included in the detection unit 1 as the detection result of the detection unit 1. The control unit 4 performs notification based on the detection result of the detection unit 1. That is, the control unit 4 performs control of causing the notification unit 2 to notify when the detection result of the detection unit 1 satisfies a preset notification condition. The notification by the notification unit 2 includes the output of the notification sound by the speaker 21, the lighting or blinking of the lamp 22, and the signal output by the signal output unit 23. The output of the notification sound includes the output of the voice message and the output of the notification sound other than the voice such as the buzzer sound. The control unit 4 has a timing function of measuring an elapsed time.

  The alarm device 100 further includes a storage unit 5 and a power supply unit 6. The storage unit 5 stores information necessary for control processing of the control unit 4 such as data of notification conditions for each detection target gas with respect to detection results, data of voice messages output by the notification unit 2, and the like. In addition, the storage unit 5 includes a non-volatile memory and the like, and is configured to rewritably store various information generated with the operation of the alarm device 100. The power supply unit 6 supplies power necessary for the operation of the control unit 4, the notification unit 2, the detection unit 1 and the storage unit 5. The power supply unit 6 may be either battery powered or external power powered or both. In the present embodiment, the power supply unit 6 is an external power supply type, and receives power supply from an external power supply via a power plug connected to an indoor power supply socket.

(Detailed configuration of control unit)
The control unit 4 is configured to perform control to notify the user of information related to the operation and the state of the alarm device 100 by outputting a voice message from the notification unit 2. The operation and state of the alarm device 100 in which notification is performed by a voice message include notification of the initial operation of the alarm device 100, notification of alarm output and suspension of alarm, notification of inspection result of the alarm device 100, monitoring operation in the installation environment Notification of the start of the alarm, history notification of the alarm output in the past, notification when an abnormality occurs in the alarm device 100, notification regarding the expiration date of the alarm device 100, and the like.

(Initial operation)
As shown in FIG. 3, the control unit 4 controls the alarm main body 10 to perform the initial operation when the power of the alarm main body 10 is turned on, and notifies the initial operation message 41 related to the execution of the initial operation. It is comprised so that control which makes 2 output may be performed. FIG. 3 shows the flow of the operation of the alarm device 100 with the lapse of time from the power-on, and the horizontal axis shows the time. When the power is turned on, for example, when the power plug of the power supply unit 6 is connected to the external power supply, but the power is inputted by the power switch when the alarm switch 10 is provided with the power switch It is. The initial operation message 41 is an example of the “first voice message” in the claims.

  The control unit 4 carries out the initial operation for the first time t1 after the power of the alarm main body 10 is turned on. The first time t1 is not particularly limited, and is, for example, 30 seconds.

  The initial operation of the alarm main body 10 is for the alarm 100 to start a normal monitoring operation (an operation to monitor whether the installation environment satisfies the notification condition for performing alarm output based on the detection result of the detection unit 1). Is an operation to be performed. Specifically, the initial operation includes an energization operation for stabilizing the output of each sensor of the detection unit 1. Since the gas sensor 11 and the CO sensor 12 are heated to a predetermined temperature (several hundreds of degrees C.) by the supply of current, there is a transient state until the output signal of the sensor is stabilized immediately after the power is turned on. The control unit 4 energizes each sensor as an initial operation during the first time t1, and stabilizes the output signal of the sensor. The control unit 4 controls so that notification based on the detection result of the detection unit 1 is not performed during the first time t1.

  Further, the initial operation of the alarm main body 10 includes the inspection operation of the alarm main body 10. The control unit 4 confirms an electric current and a voltage, whereby an abnormality of the detection unit 1 (gas sensor 11 and CO sensor 12), an abnormality of a temperature thermistor (not shown), an alarm unit 2 (speaker 21, lamp 22 and signal output) Check the abnormality of the part 23) and the abnormality of the operation part 3. Further, the control unit 4 accesses the storage unit 5 and checks the presence or absence of a data error in the storage unit 5.

  In the alarm device 100 of the present embodiment, at the time of initial operation, after the notification by the lamp 22 is first performed, the initial operation message 41 is output from the speaker 21. That is, the control unit 4 performs notification by the lamp 22 for the first time t1 after the power is turned on, and after a second time t2 shorter than the first time t1 after the power is turned on, the initial operation message Control to output 41 is performed.

  As an example of notification by the lamp 22, the control unit 4 blinks the green lamp 22. The second time t2 may be any time as long as the notification by the lamp 22 can be recognized by the user, and can be made sufficiently shorter than the first time t1. The second time t2 can be, for example, about 1 second or 2 seconds, and is shorter than half of the first time t1 (30 seconds).

  The initial operation message 41 contains information related to the implementation of the initial operation. The initial operation message 41 only needs to notify the user that the alarm device 100 is performing some operation when the power is turned on, and does not necessarily notify itself that the initial operation is being performed. As an example, the initial operation message 41 is a message "Please wait for a while until the green lamp blinks".

  In the present embodiment, after power-on, when the first time t1 elapses, the control unit 4 notifies the inspection result based on the inspection operation by a voice message. Specifically, the control unit 4 causes the notification unit 2 to output an inspection result message 42 indicating the inspection result and, when the inspection result is normal, a monitoring execution message 43 indicating that the detection unit 1 performs the monitoring operation Control to output more. The inspection result message 42 is an example of the “second voice message” in the claims. The monitoring execution message 43 is an example of the “third voice message” in the claims.

  The inspection result may include, for example, three patterns of “normal”, “failure” and “expired”. In this case, three types of inspection result messages 42 indicating inspection results are prepared. An example of the inspection result message 42 is as follows. Normal: "Alarm is normal", Failure: "It is a failure. Please contact a store." Expired: "5 years have passed since installation."

  Then, if the inspection result is normal, the control unit 4 causes the notification unit 2 to output the monitoring execution message 43 in addition to the inspection result message 42. The monitoring execution message 43 includes, for example, a message "watch for the safety of living". Therefore, when the check result is normal, a voice message "The alarm is normal. I will watch the safety of life" is output. Thereby, the control unit 4 notifies the user that the device is operating normally and that the normal monitoring operation is to be started in the form of a voice message.

  The control unit 4 performs the inspection operation of the alarm main body 10 according to the input to the operation unit 3 after the end of the initial operation (after the elapse of the first time t1). The input to the operation unit 3 is a pressing operation on the push button type operation unit 3. The input operation includes a short press operation of performing an input (press) within a predetermined time (for example, 1 second) and a long press operation of continuing input for a predetermined time (for example, 3 seconds) longer than the short press operation.

  When the short press operation is input after the end of the initial operation, the control unit 4 performs lighting and extinguishing (flashing) of each lamp 22 and an inspection operation similar to the initial operation. Control of the test operation that performs test notification (lighting or blinking) of each lamp 22 and test output of notification sound at the time of various alarm outputs when the long press operation is input after the end of the initial operation Conduct. When the operation unit 3 is continuously input for a predetermined time (for example, 10 seconds) when the long press operation is input, the control unit 4 stops the test notification of the lamp 22 and the test output of the notification sound. Let it cancel the test operation.

(Check operation)
In the present embodiment, after the end of the initial operation, the control unit 4 performs the inspection operation of the alarm main body 10 according to the input (short press operation) to the operation unit 3 and the same voice message as the inspection operation in the initial operation. Control the output of That is, even in the inspection operation based on the short press operation, the control unit 4 outputs the inspection result message 42 (any one of three patterns) indicating the inspection result, and when the inspection result is normal, the monitoring execution message 43 Perform control to make additional output.

  Moreover, the control part 4 performs control which outputs the remaining term message 44 regarding the remaining term of the term of validity of alarm device 10, when inspection operation is performed. The control unit 4 counts the accumulated time of the power-on state, acquires the remaining period of the expiration date based on the preset expiration date (five years) and the accumulated time, and outputs the remaining period message 44 as voice. . The remaining deadline message 44 to be output is, for example, a message that “the expiration date is X years and Y months later”, and the acquired remaining period is applied to the variables X and Y. The remaining time limit message 44 is an example of the “fourth voice message” in the claims.

  Moreover, the control part 4 performs control which outputs the alerting | reporting log | history message 45 regarding the newest alerting | reporting cause among the alerting | reporting implemented in the past, when inspection operation | movement is performed. When the control unit 4 performs notification based on the detection result of the detection unit 1, the control unit 4 stores the implementation history of the notification in the storage unit 5. The implementation history of the notification includes information specifying whether the notification cause corresponds to gas (detection by the gas sensor 11), CO (detection by the CO sensor 12), or failure (inspection result). Then, the control unit 4 causes the notification history message 45 corresponding to the latest notification cause stored in the storage unit 5 to be output. An example of the notification history message 45 is as follows. Gas: "There was a gas alarm," CO: "There was a CO alarm," Failure: "There was a failure alarm."

  In addition, while the failure is occurring, the control unit 4 continuously performs notification (for example, blinking of the green lamp 22) indicating the failure due to the lamp 22, and an alarm sound , "Is a failure") periodically (for example, every minute).

  In this state, when a short press operation or a long press operation is input, the control unit 4 outputs a voice message that "It is a malfunction, please contact a dealer, stop the alarm", and malfunction by the speaker 21 End the output of the notification sound indicating. In the case of the failure notification, it is not the suspension of the notification sound but the end of the notification sound output, and once the operation input is performed, the notification sound output is not performed periodically thereafter. The control unit 4 continues the notification indicating the failure by the lamp 22 even when the output of the notification sound indicating the failure is ended according to the operation input. Further, while a failure occurs, the control unit 4 only outputs a notification indicating a failure due to the speaker 21 in response to the operation input. The control unit 4 periodically performs a return determination, and when normal, ends the notification indicating a failure, and returns to the normal monitoring operation.

  Therefore, in the case where the notification history of the failure is output in the above-described notification history message 45, the failure has occurred in the past and notification has been made, and it is now normal.

(Monitoring operation)
Next, the monitoring operation based on the detection result of the detection unit 1 will be described. The control unit 4 performs the monitoring operation based on the detection result of the detection unit 1 after the alarm main body 10 is initially operated. During the monitoring operation, the control unit 4 determines whether the detection result of the detection unit 1 satisfies a predetermined notification condition, and causes the notification unit 2 to notify (alarm output) when the detection result satisfies the notification condition. Take control. The notification by the notification unit 2 includes lighting or blinking of the lamp 22 and an output of a notification sound. The notification sound includes at least one of a predetermined buzzer sound and an audio message indicating an alarm.

  FIG. 4 shows the flow of the operation of the alarm device 100 with the passage of time since the start of the notification, and the horizontal axis shows the time. In the first embodiment, when the control unit 4 receives an input to the operation unit 3 during notification based on the detection result of the detection unit 1, the control unit 4 outputs a pause message 51 regarding the notification stop period SP to the notification unit 2 (voice output And the control of temporarily stopping the notification sound.

  That is, in the alarm device 100 of the present embodiment, when the user operates the operation unit 3 during notification based on the detection result of the detection unit 1, the notification sound is temporarily stopped for a predetermined notification stop period SP. And a pause message 51 is output when pausing. When the control unit 4 suspends the notification sound, it counts (counts) the duration time of the suspension. Further, the control unit 4 is configured to continue the notification (lighting or blinking) by the lamp 22 even while the notification sound is paused.

  The pause message 51 is not particularly limited as long as it includes information on the notification suspension period SP. In the present embodiment, the pause message 51 includes a value of time preset as the notification pause period SP. That is, the pause message 51 includes a message about the length of time for which the notification sound should be stopped or after which time the notification stop should be canceled. For example, the pause message 51 is a message "Stop alarm for 5 minutes". In this case, the notification stop period SP is five minutes. Thus, the temporary stop message 51 of the present embodiment indicates that the output of the notification sound is to be stopped (“stop the alarm”), and the information on the length (“5 minutes”) of the notification stop period SP. It contains.

  In the present embodiment, when the pause message 51 is output when the notification sound is paused, the time during which the pause message 51 is output is included in the notification suspension period SP. That is, when suspending the notification sound, the control unit 4 causes the notification unit 2 to output the temporary stop message 51 instead of the output of the notification sound, and pauses the period during which the temporary stop message 51 is output. Control to be included in the notification stop period SP in which The phrase "instead of the output of the notification sound" may be reworded as "stop the output of the notification sound". Therefore, the notification stop period SP is counted as a time when the output of the notification sound is actually stopped. Then, the notification stop period SP includes the time during which the voice other than the notification sound (pause message 51) is output.

  During the notification stop period SP, when the detection result of the detection unit 1 continues and satisfies the notification condition, the control unit 4 resumes the output of the notification sound when the notification stop period SP has elapsed. In this case, the control unit 4 is configured to perform control to continue the output to the input to the operation unit 3 without stopping the output of the notification sound after resuming the output of the notification sound. That is, in the alarm device 100, when the user temporarily suspends the output of the notification sound and the notification is resumed by continuing the state where the notification condition is satisfied (case of (A) in FIG. 4), You can not pause the notification sound again (stop again). For this reason, the control unit 4 stores the pause acceptance information in the storage unit 5 when the notification sound is paused according to the input to the operation unit 3 (when the pause message 51 is output). The suspension acceptance information can be reworded as information on the number of acceptances of the suspension operation.

  The control unit 4 controls the notification unit 2 to output the notification restart message 52 to the effect that the notification is not stopped even if the input to the operation unit 3 is performed again when the output of the notification sound is resumed after the temporary stop. The notification restart message 52 allows the user to understand that the notification sound can not be stopped even if the same operation as the first pause is performed.

  The notification restart message 52 may be output when the output of the notification sound is paused (when the pause message 51 is output), or may be output when the output of the notification sound after the pause is resumed. In the present embodiment, the control unit 4 is configured to perform control to output the notification resumption message 52 when the output of the notification sound is resumed after the notification stop period SP has elapsed.

  The notification resumption message 52 is, for example, a message “Restart alert, can not stop alert next”. As described above, the notification restart message 52 of the present embodiment restarts the output of the notification sound (“restart the alarm”) and does not stop the notification even if the input to the operation unit 3 is performed again ( Contains information about "Next can not stop the alert".

  When the input to the operation unit 3 is performed after the output of the notification sound is resumed, the control unit 4 outputs a stop impossibility message 53 indicating that the notification sound can not be stopped and continues the output of the notification sound. The unstoppable message 53 is, for example, a message that “the alert can not be stopped”.

  When the gas concentration is reduced during the notification stop period SP and the notification condition is not satisfied (case of (B) in FIG. 4), the output of the notification sound is not resumed after the notification stop period SP has elapsed. The notification resumption message 52 is also not output. In this case, when an event that satisfies the notification condition occurs next, the control unit 4 can receive a pause based on an input to the operation unit 3. That is, the control unit 4 is configured to reset the number of receptions of the pause based on the input to the operation unit 3 when the detection result of the detection unit 1 does not satisfy the notification condition during the notification stop period SP. ing. Specifically, the control unit 4 clears the temporary stop acceptance information stored in the storage unit 5 (when the information is erased) when the detection result of the detection unit 1 does not satisfy the notification condition. Reset the count. As a result, when an event satisfying the notification condition occurs next (see the two-dot chain line in FIG. 4), if the user performs an operation input, the notification sound is paused and the pause message 51 is output.

(Informing conditions)
Next, details of the notification condition will be described with reference to FIG. The notification condition may be set for each detection target gas. That is, different notification conditions are set for each of the fuel gas and the CO gas. Further, the notification condition may include a plurality of conditions according to the concentration of the detection target gas. In the present embodiment, the notification conditions include a first condition C1 of an alarm level having a relatively high concentration, and a second condition C2 of a caution level whose detected gas concentration is lower than the first condition C1. The control unit 4 is configured to cause the notification unit 2 to perform different notification operations for each detection target gas when the first condition C1 is met and when the second condition is met. The condition corresponding to the first condition is a case where the detected gas concentration exceeds the upper limit concentration of the second condition and is equal to or less than the upper limit concentration of the first condition. The second condition corresponds to the case where the detected gas concentration exceeds the lower limit concentration of the second condition and is equal to or less than the upper limit concentration of the second condition. In addition, the control unit 4 is configured to invalidate the control of the temporary stop of the notification sound and the output of the temporary stop message 51 when the specific notification condition of the specific gas type is satisfied.

<Fuel gas (city gas, LP gas)>
For fuel gas (city gas, LP gas), the first condition C1a of the alarm level and the second condition C2a of the caution level are set in the storage unit 5 according to the gas concentration based on the detection result of the gas sensor 11 There is. When the detection result (detection gas concentration) of the fuel gas falls under the first condition C1a, the control unit 4 gives notification by lighting (continuous lighting) of the red lamp 22 and notification by output of notification sound from the speaker 21. Do each one. Then, when the detection result of the fuel gas (city gas or LP gas) corresponds to the first condition C1a, the control unit 4 temporarily outputs the temporary stop message 51 and the notification sound according to the input to the operation unit 3 Control the stop.

  On the other hand, when the detection result of the fuel gas corresponds to the second condition C2a, the control unit 4 performs notification by blinking of the red lamp 22 and does not output the notification sound. Since the notification sound is not output, the output of the pause message 51 and the suspension of the notification sound are not performed.

<CO gas>
For the CO gas, the first condition C1b of the alarm level and the second condition C2b of the caution level are set in the storage unit 5 according to the gas concentration based on the detection result of the CO sensor 12. When the detection result of the CO gas corresponds to the first condition C1b, the control unit 4 performs notification by lighting (continuous lighting) of the yellow lamp 22 and notification by output of a notification sound from the speaker 21. Then, when the CO gas detection result corresponds to the first condition C1b, the control unit 4 is configured to perform control to continue the output without stopping the notification sound even if the input to the operation unit 3 is received. It is done. That is, when the control unit 4 falls under (gas type: CO gas, notification condition: first condition C1 b), the control for performing the above-described suspension of the notification sound and the output of the suspension message 51 is invalidated.

  On the other hand, when the detection result of CO gas corresponds to the second condition C2b, the control unit 4 performs notification by blink of the yellow lamp 22 and notification by output of notification sound from the speaker 21 respectively. Then, when the CO gas detection result corresponds to the second condition C2b, the control unit 4 controls the output of the temporary stop message 51 and the temporary stop of the notification sound according to the input to the operation unit 3. It is configured.

(Other voice message output function)
Next, other voice message output functions will be described. The alarm device 100 has a switching function of notification sound based on the detection result of the detection unit 1. The control unit 4 shifts to the notification sound setting mode by receiving a predetermined operation.

  When transitioning to the notification sound setting mode, the control unit 4 outputs a voice message including information indicating that the setting to the notification sound setting mode has been made, information on a setting method, and current setting information. Specifically, at the time of mode transition, the control unit 4 outputs a voice message "Change alarm sound. Please press the switch to select. The current setting is Japanese."

  In the notification sound setting mode, the control unit 4 switches the notification sound and causes the notification unit 2 to output the notification sound each time an input operation (pressing operation) to the operation unit 3 is received. The type of notification sound is not particularly limited, but as an example, four types can be selected: Japanese voice message, English voice message, Chinese voice message, and buzzer sound only not including voice message. Be done. For example, every time the control unit 4 accepts an input operation, the control unit 4 outputs a voice message indicating the type of an alarm sound of "Japanese", "Buzzer", "English", and "Chinese". The control unit 4 confirms the selection of the type of the notification sound by the user performing a predetermined operation (for example, the long press operation of the operation unit 3) in the state where the voice message indicating the type of the notification sound to be selected is output. And set in the storage unit 5.

When the type of the notification sound is set in the notification sound setting mode, the control unit 4 outputs a notification sound (alarm, attention) based on the detection result of the detection unit 1 by the set type of notification sound. Each notification sound is, for example, as follows, as an example (a warning level of fuel gas).
Japanese: "Woo, pip pip, gas leaks?"
Buzzer sound: "Woo, pippi pipi"
English: "Woo, pippippi, (in English" is there any gas leaking ")"
Chinese: "Woo, pippi, (in Chinese," Is there any gas leaking? "
Note that “Woo-Woo”, “Pip-Pip-Pi”, etc. indicate buzzer sounds in onomatopoeic language for the sake of convenience.

(Control processing of initial operation and inspection operation)
Next, with reference to FIG. 6, the control processing at the time of initial operation of alarm device 100 by control part 4 is explained.

  First, when the power of the alarm main body 10 is turned on, in step S1, the control unit 4 starts an initial operation and starts notification by the lamp 22. The control unit 4 counts an elapsed time since the power is turned on. In step S2, the control unit 4 determines whether or not the second time t2 has elapsed since the power supply was turned on. When the second time t2 has elapsed, the control unit 4 causes the notification unit 2 to output the initial operation message 41 in step S3. The controller 4 repeats the determination of step S2 until the second time t2 elapses.

  In step S4, it is determined whether or not the first time t1 has elapsed since the power was turned on, and the determination in step S4 is repeated until the first time t1 has elapsed. If the first time t1 has elapsed, the control unit 4 advances the process to step S5, and outputs an inspection result message 42 according to the inspection result (“normal”, “fault”, “expired date”) to the notification unit 2 Let In step S6, the control unit 4 determines whether the inspection result is "normal", and when the inspection result is "normal", causes the notification unit 2 to output the monitoring execution message 43 in step S7. , Then finish the process. In step S6, when the inspection result is not "normal", the control unit 4 ends the process without outputting the monitoring execution message 43.

  As described above, the process of the initial operation is performed.

(Short press check)
Although the description by the flowchart is omitted, when the inspection result is determined to be normal and the initial operation is finished, the control unit 4 starts the monitoring operation based on the detection result of the detection unit 1. In this state, the control unit 4 determines whether or not an input (short press operation) is made to the operation unit 3, and if the short press operation is performed, the inspection operation is started and notification processing of the inspection result (FIG. 3) See).

  In the notification processing of the inspection result, the control unit 4 performs the processing of steps S5 to S7, and outputs the inspection result message 42 and the monitoring execution message 43 when the inspection result is normal. In addition, the control unit 4 acquires the remaining period of the expiration date and causes the notification unit 2 to output the remaining period message 44, and notifies the notification history message 45 based on the notification execution history stored in the storage unit 5. Make part 2 output.

(Informing operation)
Next, with reference to FIG. 7, the notification operation during the monitoring operation and the suspension process of the notification sound by the control unit 4 will be described. Hereinafter, for convenience, the output of the notification sound by the speaker 21 will be described, and the description of the control of the notification by the lamp 22 will be omitted.

  In step S11, the control unit 4 determines whether the detection result of the detection unit 1 corresponds to any of the notification conditions (the first condition C1 and the second condition C2). The control unit 4 advances the process to step S12 when any of the notification conditions is met, and advances the process to step S23 when the notification conditions are not met.

  In step S12, the control unit 4 determines whether or not the notification sound is temporarily stopped (during the notification stop period). The control unit 4 advances the process to step S13 when not being paused, and advances the process to step S19 when being paused.

  In step S13, the control unit 4 determines whether an operation input to the operation unit 3 has been received. When the control unit 4 does not receive the operation input, the process proceeds to step S14, and in step S14, the control unit 4 causes the notification sound corresponding to the notification condition (first condition, second condition) corresponding to the detection result to be output. If the notification sound is being output, the control unit 4 continues the output. If the controller 4 determines in step S13 that there is an operation input, the process proceeds to step S15.

  In step S15, the control unit 4 determines whether temporary stop of the notification sound is possible. That is, when the detection result of the detection unit 1 corresponds to the first condition C1b of CO for which the temporary stop is invalid, the control unit 4 determines that the temporary stop is impossible. Even when the second condition C2b of CO that can be temporarily stopped or the first condition C1a of fuel gas is satisfied, the temporary stop acceptance information is stored in the storage unit 5 (the temporary stop of the notification sound has already been made The control unit 4 also determines that the temporary stop is not possible even when it is in progress. If suspension of the notification sound is not possible, the control unit 4 proceeds to step S14 to output the notification sound. Although simplified in FIG. 7, when the process of step S14 is performed via step S15, unlike the case where step S15 is not performed, the control unit 4 sends a stop impossible message 53 (not shown) in response to the user's operation input. 4) is output to the notification unit 2, and the output of the notification sound is continued.

  When the temporary stop of the notification sound is possible, the control unit 4 suspends the output of the notification sound in step S16 and starts counting of the notification stop period SP. Then, in step S17, the control unit 4 causes the temporary stop message 51 to be output, and in step S18, causes temporary stop acceptance information to be stored in the storage unit 5, and thereafter the processing ends.

  On the other hand, in the case where the detection result of the detection unit 1 corresponds to the notification condition and the notification sound is temporarily stopped in step S12, the control unit 4 proceeds to step S19 and the notification stop period SP is Determine if it has elapsed. If the notification stop period SP has not elapsed, the control unit 4 proceeds to step S20 and continues the output stop of the notification sound. If the notification stop period SP has elapsed, the control unit 4 causes the notification unit 2 to output the notification restart message 52 in step S21, cancels suspension of the notification sound in step S22, and ends the processing.

  In step S11, when the detection result of the detection unit 1 does not correspond to any notification condition, the control unit 4 resets the temporary stop acceptance information stored in the storage unit 5 in step S23. Then, in step S20, the control unit 4 stops the notification sound if notification is in progress, and continues the state in which the notification sound is stopped if notification is not in progress, and ends the processing.

(Effect of this embodiment)
In the present embodiment, the following effects can be obtained.

  In the present embodiment, as described above, when the initial operation is performed at the time of power on, the initial operation message 41 related to the execution of the initial operation is output. Can understand. Therefore, unlike in the case where the state of the alarm device 100 is notified by blinking of the lamp 22 without any voice output, for example, during the initial operation, it is initially determined that the alarm device 100 normally performs the necessary operation. It can be grasped by the operation message 41. As a result, the user can appropriately grasp the state of the alarm device 100 when the power is turned on.

  Further, in the present embodiment, as described above, the control unit 4 performs notification by the lamp 22 for the first time t1 after the power is turned on, and after the power is turned on, the control unit 4 performs Since the control for outputting the initial operation message 41 is performed after the lapse of two hours t2, the user can be notified of the initial operation message 41 after the second time t2 elapses after the notification is started by the lamp 22 for the initial operation. That is, the initial operation message 41 can be transmitted after the user's attention is first drawn by the lamp 22. As a result, it is possible to make the user understand the state of the alarm device 100 at the time of power on without performing an unexpected operation of the user.

  Further, in the present embodiment, as described above, the initial operation includes the inspection operation of the alarm main body 10, and the control unit 4 causes the notification unit 2 to output the inspection result message 42 indicating the inspection result. Since the control to further output the monitoring execution message 43 to the effect that the detection operation is performed by the detection unit 1 is performed when it is normal, not only notifying the inspection result but also monitoring that the alarm device 100 performs the monitoring operation It can be notified by the execution message 43. That is, after outputting the initial operation message 41 when the power is turned on, only by notifying the inspection result (inspection result message 42), the user grasps whether or not any operation is necessary to cause the alarm device 100 to perform the monitoring operation. Can not do it. Therefore, by outputting the monitoring execution message 43 when the inspection result is normal, it is possible to make the user understand that the alarm device 100 has started the normal monitoring operation, so the alarm device 100 can be more appropriately displayed. The user can be made to understand the state of

  In the present embodiment, as described above, the control unit 4 performs the inspection operation of the alarm main body 10 according to the input to the operation unit 3 after the end of the initial operation, and the same as the inspection operation in the initial operation. Since voice message output control is performed, in addition to the initial operation, even when the user voluntarily performs the inspection operation, the inspection result message 42 similar to the initial operation and the monitoring execution message (in the normal case) 43 Can be output. By outputting the same voice message as the time of inspection in the initial operation, the user can grasp the state of the alarm device 100 without misunderstanding. Moreover, since it can suppress that the pattern of an audio | voice message is increased unnecessarily, it can suppress that the storage capacity of the audio | voice message in the alarm device 100 is increased.

  Further, in the present embodiment, as described above, when the control unit 4 performs the inspection operation according to the operation input, the control for causing the remaining period message 44 regarding the remaining period of the expiration period of the alarm main body 10 to be output Since it carries out, the user can grasp the remaining period until the replacement time of the alarm 100 by the remaining time limit message 44 outputted when the inspection operation is performed. As a result, the user can appropriately grasp the state of the alarm 100 regarding the expiration date.

  Further, in the above embodiment, an example in which the output is continued without stopping the output of the notification sound in response to the input to the operation unit 3 after the output of the notification sound is resumed (the pause is not received) has been described. Is not limited to this. In the present invention, even after the output of the notification sound is resumed, the operation input of the pause may be received to pause the notification sound. Further, the number of times of accepting the temporary stop operation input may be a predetermined number of times instead of one, and the process of temporary stop according to the operation input may be limited to a predetermined number of times.

  Moreover, although the example which includes the period which is outputting the temporary stop message 51 in alerting | reporting stop period SP was shown in the said embodiment, this invention is not limited to this. In the present invention, the period during which the temporary stop message 51 is output may not be included in the notification stop period SP.

  In the above embodiment, an example is shown in which the number of temporary stop acceptance is reset when the detection result of the detection unit 1 does not satisfy the notification condition during the notification stop period SP, but the present invention is limited thereto. I can not. In the present invention, it is not necessary to reset the number of acceptances of the temporary stop.

  Further, in the above embodiment, when the detection result of the CO gas falls under the first condition C1b, even if the input to the operation unit 3 is received, the notification sound is output without being stopped (the temporary stop processing is invalidated) Although an example is shown, the present invention is not limited to this. In the present invention, even when the detection result of the CO gas falls under the first condition C1b, the process of temporarily stopping the notification sound may be performed.

  In the above embodiment, the input operation is performed when the detection result of the CO gas corresponds to the second condition C2b and when the detection result of the fuel gas (city gas or LP gas) corresponds to the first condition C1. Although the example which performs the process of the temporary stop of the alerting | reporting sound according to was shown, this invention is not limited to this. In the present invention, in these cases, even if the input is accepted, the notification sound may be output without being stopped (the pause process may be invalidated).

  In the above embodiment, an example is shown in which the initial operation message 41 is output after the second time t2 has elapsed after the power is turned on, but the present invention is not limited to this. In the present invention, the initial operation message 41 may be output immediately after the power is turned on. That is, the initial operation message 41 may be output simultaneously with the notification by the lamp 22 when the power is turned on.

  Moreover, although the example which performs the inspection operation | movement of the alarm main body 10 as initial operation was shown in the said embodiment, this invention is not limited to this. In the present invention, the inspection operation of the alarm main body 10 may not be performed as the initial operation. Also, the inspection result message 42 may not be output.

  Moreover, although the example which outputs the monitoring execution message 43 when the check result is normal was shown in the said embodiment, this invention is not limited to this. In the present invention, when the inspection result is normal, the monitoring execution message 43 may not be output.

  Further, in the above embodiment, after the end of the initial operation, the inspection operation of the alarm main body 10 is performed according to the input (short press operation) to the operation unit 3 and the same voice as the inspection operation in the initial operation Although the example which performs output control of a message was shown, the present invention is not limited to this. In the present invention, at the time of the check operation by the short press operation, an audio message different from the check operation in the initial operation may be output.

  In the above embodiment, the input operation to the operation unit 3 is divided into the short press operation and the long press operation, and the check operation of the alarm main body 10 is performed according to the short press operation. The invention is not limited to this. In the present invention, the inspection operation of the alarm main body 10 may be performed according to the long press operation. In addition, the inspection operation of the alarm main body 10 may be performed when there is an input to the operation unit 3 without distinguishing between the short press operation and the long press operation.

  Further, in the above embodiment, when the inspection operation is performed according to the operation input to the operation unit 3, an example is shown in which the remaining time limit message 44 regarding the remaining time limit of the validity time of the alarm main body 10 is output. The invention is not limited to this. In the present invention, the remaining deadline message 44 may not be output.

  In the above embodiment, for convenience of explanation, the processing of the control unit has been described using a flow-driven flow that sequentially processes along the processing flow, but for example, the processing operation of the control unit is performed on an event basis. It may be performed by event-driven (event-driven) processing that executes processing. In this case, the operation may be completely event driven, or the combination of event driving and flow driving may be performed.

  Moreover, the specific example of the content of the various voice messages demonstrated in the said embodiment is an example to the last, and is not limited to the content demonstrated in the said embodiment. Any voice message may be different from the content described in the above embodiment.

  For example, with regard to the temporary stop message 51, at least the information stop related to the notification stop period SP is that the output stop of the notification sound is temporary (temporary stop) and is not an indefinite stop (end of the notification). It is sufficient if the information is included, and it is not necessary to specify the length of the pause period. For example, the pause message 51 may be a message such as “stop broadcasting for a certain period of time”.

  Also, for example, the initial operation message 41 is not a message indicating the execution of the initial operation "Please wait for a while until the green light blinks", but the execution of the initial operation such as "Perform the initial operation". It may be a message directly indicating

  Further, the specific examples of the various times (first time t1, second time t2, and notification stop period SP) exemplified in the above embodiment are merely an example, and may be different from the contents described in the above embodiment. Good.

  Moreover, although the example which the alerting | reporting part 2 equips with the speaker 21 was shown in the said embodiment, this invention is not limited to this. In the present invention, the notification unit 2 may be provided with a buzzer (electronic buzzer, piezoelectric buzzer) instead of the speaker 21. It is also possible to output a voice message by a buzzer.

  Moreover, although the example which continues the alerting | reporting (lighting or blink) by the lamp | ramp 22 was shown also during temporary stop of the alerting sound in the said embodiment, this invention is not limited to this. In the present invention, the notification by the lamp 22 may be temporarily stopped (that is, the lamp 22 may be turned off) while the notification sound is temporarily stopped.

  Moreover, although the example which outputs the stop impossibility message 53 was shown when the input to the operation part 3 was performed in the said embodiment, this invention is not limited to this. In the present invention, the alarm may be configured not to output the stop impossible message 53. In addition, when the first input to the operation unit 3 is performed at the time of the output of the alarm sound, the alarm is issued so that the stop impossible message 53 is output and the stop impossible message 53 is not output after the second input. May be configured. Furthermore, according to the type of the notification conditions (one of the first conditions C1a and C1b and the second conditions C2a and C2b) corresponding to the output of the notification sound, it is separately set whether to output the stop impossible message 53 or not. May be

  As a specific example, in the case where the process of step S14 is performed via steps S13 and S15 in FIG. 7, for example, when the first condition C1b of CO gas is satisfied, the first input to the operation unit 3 is If it has been performed, the stop impossibility message 53 is output in step S14, and the stop impossibility message 53 is not output in step S14 after the second and subsequent inputs. On the other hand, when the first condition C1a of the fuel gas (city gas or LP gas) is satisfied, even if the input to the operation unit 3 is received, the stop impossible message 53 is not output in step S14. The alarm may be configured as described above.

  In the above embodiment, the first condition C1 of the notification condition includes the upper limit concentration of the second condition C2 as the lower limit value, the upper limit concentration of the first condition C1 as the upper limit value, and the second condition C2 as the lower limit value. Although an example is shown in which each condition is set by the upper limit value and the lower limit value so as to include the lower limit concentration of the two conditions C2 and the upper limit concentration of the second condition C2 as the upper limit, the present invention is not limited thereto. In the present invention, the notification conditions (the first condition and the second condition) may be set so as to include only a single threshold, and the notification conditions may be satisfied when the set threshold is exceeded.

  In the above embodiment, the notification condition includes two steps of the first condition C1 of the alarm level and the second condition C2 of the attention level. However, the present invention is not limited to this. In the present invention, only one step (only the first condition) may be set as the notification condition. Further, three or more stages of conditions may be set as the notification conditions.
