Description

  The present invention relates to an alarm device, and more particularly, to an alarm device that issues an alarm using a notification sound.

  2. Description of the Related Art Conventionally, an alarm device that performs an alarm using a notification sound is known (for example, see Patent Document 1).

  Patent Document 1 discloses an alarm device that outputs a sound alarm from a speaker when a fire, CO, or CH4 (methane) is detected. In this alarm device, the alarm output is stopped when the switch is operated for several seconds or more while the audio alarm is being output. And while this alarm is stopped, (1) the indicator light blinks, (2) the buzzer is turned on periodically at a low volume, and (3) “alarm is stopped”. Any one of (4) regularly outputting melody sound is performed to notify that the alarm is stopped. The alarm device of Patent Document 1 cancels the alarm stop state after 10 minutes from the alarm stop, and outputs the alarm again if it is in the alarm state at that time.

  Such an alarm stop function enables the user to prevent the alarm output from being continued unnecessarily by the user's own operation during the alarm output.

JP 2010-152920 A

  However, in the alarm device of the above-mentioned patent document 1, when only the alarm is stopped when the alarm is stopped, the alarm output is performed again after a predetermined time has elapsed, so the user stopped the alarm. Nevertheless, there may be an impression that the alarm was suddenly resumed later. That is, since there is a possibility that the user's intention that the alarm is stopped by the operation input and the operation of the alarm device that the alarm output is resumed after a predetermined time elapses, in the conventional alarm device, There is a problem that it is difficult for the user to accurately grasp the operation of the alarm device in response to the operation input.

  In particular, in general household gas alarms, etc., it is not likely that the user knows the specifications of the alarm from the instruction manual, etc., and the frequency of alarm output is low in the home. From the point of safety of the user, it is also necessary for the user to accurately grasp the operation of the alarm device in response to the operation input once the alarm output is performed due to the fact that the input is rare. This is also important from the viewpoint of convenience of the alarm device for the user.

  The present invention has been made to solve the above-described problems, and one object of the present invention is to allow a user to appropriately grasp the operation of an alarm device in response to an operation input at the time of alarm. Is to provide an alarm.

Alarm according to the first aspect of this invention includes a detector for detecting at least one of gas and fire, and a notification unit that performs a notification by alarm sound, an operation unit for accepting an operation input, the detection of the detecting unit A control unit that, when receiving an input to the operation unit during notification based on the result, outputs a first voice message related to the notification stop period to the notification unit and performs control to temporarily stop the notification sound. After restarting the output of the notification sound, it is configured to perform control to continue the output without stopping the output of the notification sound with respect to the input to the operation unit. When the output of the notification sound is resumed after the pause, the operation unit Control is performed to cause the notification unit to output a second voice message indicating that the notification is not stopped even if input is performed again.
An alarm device according to a second aspect of the present invention includes a detection unit that detects city gas or LP gas and carbon monoxide gas, a notification unit that performs notification using a notification sound, and an operation unit that receives an operation input. A control unit that controls to temporarily stop the notification sound while outputting the first voice message related to the notification stop period to the notification unit when receiving an input to the operation unit during the notification based on the detection result of the detection unit. When the detection result of the city gas or LP gas corresponds to the first condition, the control unit controls the output of the first voice message and the suspension according to the input to the operation unit, and the carbon monoxide gas When the detection result corresponds to the first condition, control is performed to continue the output without stopping the notification sound even when an input to the operation unit is received.

  In the present specification, the “first voice message related to the notification stop period” is a message including information related to the period for stopping the notification, and a message for notifying a specific time (such as 5 minutes) as the period for stopping the notification. Not only the length of the notification stop period, but also a message indicating that there is a period to stop notification (such as not stopping indefinitely), such as “Stop notification for a certain period of time” It is a broad concept including In addition, the “voice message” is used to transmit information to the user by pronouncing a language among the notification sounds, and the “notification sound” is used to notify the user of not only a voice message but also a buzzer sound. Refers to the overall sound output to.

In the alarm device according to the first and second aspects of the present invention, according to the above configuration, when the user performs an input operation on the operation unit to temporarily stop the notification sound, At least, it is possible to inform the user that the notification stop based on the user's input operation is not an indefinite stop, but a temporary stop with a fixed notification stop period. In addition, since the first voice message can be output at the timing of starting the pause of the notification sound, when the user stops the notification, the stop of the notification is temporary and the stop state is released later. It is possible to foresee the operation of the alarm device. Thereby, a user can grasp | ascertain appropriately the operation | movement of the alarm device with respect to the operation input at the time of an alarm. As a result, even when the output of the notification sound is resumed when the suspension of the notification sound is canceled, it is avoided to give the user the impression that an unexpected operation has been suddenly performed for the user. it can.
Further, in the alarm device according to the first aspect, when the notification state has not been eliminated even after the notification stop period has elapsed, the notification sound is not temporarily stopped even if the user performs an operation input. And alert people around you. On the other hand, as a user, when the operation input is not accepted after the notification is resumed even though the notification sound is stopped once, the user's intention and the operation of the alarm device do not match. There is a possibility of suspected failure. Therefore, since the second voice message can make the user know that it cannot be temporarily stopped when the notification is resumed, even when the control for invalidating the restart of the notification sound is performed, the operation of the alarm device with respect to the operation input, The user can be grasped appropriately.
In the alarm device according to the second aspect, the user's intention can be prioritized for the city gas or the LP gas, and the output of the first voice message and the temporary stop can be controlled. On the other hand, for carbon monoxide gas with high risk, even if input to the operation unit is accepted, control is made to continue the output without stopping the alarm sound, so that the user and the surrounding people can be more cautioned. Can be urged.

In the alarm device according to the first aspect, preferably, the control unit performs control to output the second voice message when the output of the notification sound is resumed after the notification stop period has elapsed. Here, the second voice message may be output together with the first voice message. In this case, the user may forget the content of the second voice message after the notification stop period has elapsed. . Further, the user may solve the cause of the notification during the notification stop period, and in this case, it is not necessary to output the second voice message. Therefore, when the output of the notification sound is resumed after the notification stop period has elapsed, the second voice message is output so that the user can more appropriately recognize that the temporary stop is not accepted only when necessary. Can do.

In the alarm device according to any of the first and second aspects, preferably, the first voice message includes a time value set in advance as a notification stop period. The time value is a numerical value such as “5 minutes” or “300 seconds”. For example, in a message such as “I will stop the notification for a certain period of time”, it is not possible to know when the notification is resumed even though it is possible to know that the notification stop is temporary. If comprised, a user can be made to grasp | ascertain correctly the information of when alerting | reporting is restarted.

In the alarm device according to any one of the first and second aspects, preferably, when performing a temporary stop, the control unit causes the notification unit to output a first voice message instead of outputting the notification sound, and first Control is performed so that the period during which the voice message is output is included in the notification stop period during which the voice message is temporarily stopped. If comprised in this way, it replaces with the output of an alerting sound, and since a 1st audio | voice message is output, it is easy to convey the content of a 1st audio | voice message to a user. In this case, while the first voice message is being output, the notification sound is not already output, so by adding the period during which the first voice message is output to the notification stop period, The pause can be controlled without giving the user a sense of incongruity about the length of the notification stop period.

In the alarm device according to the first aspect, the control unit preferably receives the number of suspensions based on an input to the operation unit when the detection result of the detection unit does not satisfy the notification condition during the notification stop period. Is configured to reset. Here, for example, when a condition that satisfies the notification condition occurs again after the notification condition is not satisfied during the notification stop period, the cause of the notification that occurred first and the notification cause that satisfied the notification condition during the notification stop period are: , May be due to different events. Therefore, by resetting the number of times suspension is accepted once the notification condition is no longer satisfied, the user can perform a pause operation for the notification based on the newly generated notification cause.

In the alarm device according to the second aspect, preferably, the control unit inputs to the operation unit when the detection result of the carbon monoxide gas corresponds to the second condition in which the detected gas concentration is lower than the first condition. In response to this, the output of the first voice message and the suspension control are performed. If comprised in this way, even if it detects carbon monoxide gas, while the detected gas density | concentration is low, the operation | movement which gave priority to a user's intention is performed by controlling the output of a 1st audio | voice message, and a pause. be able to.

  According to the present invention, as described above, the user can appropriately grasp the operation of the alarm device in response to the operation input at the time of alarm.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

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

(Whole structure of alarm device)
An alarm device 100 shown in FIG. 1 is a gas alarm device that notifies a user of a gas leak. The alarm device 100 is installed indoors, for example, and detects a detection target gas present in the installation environment. The alarm device 100 can notify a gas leak of fuel gas that is city gas or LP gas, for example. For example, the alarm device 100 can notify 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 for business use or for both home use and business use. An alarm device 100 shown in FIG. 1 is an example of a wall-mounted alarm device attached to an indoor wall surface. Alarm device 100 may be a ceiling-mounted type that can be 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). 1 and 2, the alarm device 100 includes an alarm device body 10 in which a detection unit 1, a notification unit 2, an operation unit 3, and a control unit 4 are incorporated in a housing.

  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. The abnormal detection of gas and fire is to detect gas leakage and heat (temperature) or smoke generated by the fire. The detection unit 1 may further detect other than gas and fire.

  In the example illustrated in FIG. 2, the detection unit 1 is configured to detect fuel gas (city gas or LP gas) and carbon monoxide gas. Specifically, the detection unit 1 includes a gas sensor 11 (see FIG. 2) that detects fuel gas (city gas or LP gas) and a CO sensor 12 (see FIG. 2) that detects CO gas. The structure of the sensor and the detection principle are not particularly limited. As an example, the gas sensor 11 and the CO sensor 12 are configured by a semiconductor type gas detection element, and specifically, can be configured by a hot wire type semiconductor type gas sensor. The hot-wire semiconductor gas sensor detects the concentration of the detection target gas by utilizing the fact that the electric conductivity changes when the detection target gas is adsorbed on the surface of the element heated to a predetermined temperature (several hundred degrees C) by supplying current. It is configured. The gas sensor 11 detects methane contained in the fuel gas as the 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 bringing ambient gas into contact with the detection unit 1 in the housing.

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

  The speaker 21 outputs a predetermined notification sound under the control of the control unit 4. The speaker 21 outputs a predetermined voice message under the control of the control unit 4. The alarm device body 10 is formed with an opening 10b (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 by being controlled by the control unit 4. The lamp 22 is constituted by an LED light source, for example. One or a plurality of lamps 22 are provided. In the example of FIG. 1, three lamps 22 are provided in the alarm device body 10. The three lamps 22 generate light of different colors (for example, red, yellow, and green). As an example, the red lamp 22 performs notification regarding the fuel gas (gas sensor 11), the yellow lamp 22 performs notification regarding the CO gas (CO sensor 12), and the green lamp 22 includes a power supply other than the detection gas, Notifications regarding malfunctions and other operations of the alarm device 100 are made. The signal output unit 23 includes 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 security device).

  The operation unit 3 is configured to accept 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 includes a push button type switch provided in the alarm device body 10. The alarm device body 10 is provided with one operation unit 3. The operation unit 3 receives an input operation (pressing operation) and outputs an input signal to the control unit 4. The alarm device body 10 may include a plurality of operation units 3.

  As shown in FIG. 2, the control unit 4 performs control processing for each unit included in the alarm device 100. The control unit 4 includes a processor (arithmetic processing device) such as a CPU or a microcomputer. The control unit 4 acquires a signal of each sensor included in the detection unit 1 as a 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 for 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 output of a notification sound by the speaker 21, lighting or blinking of the lamp 22, and signal output by the signal output unit 23. The output of the notification sound includes the output of a voice message and the output of a notification sound other than sound such as a buzzer sound. The control unit 4 has a time measuring function for measuring elapsed time.

  The alarm device 100 includes a storage unit 5 and a power supply unit 6. The storage unit 5 stores information necessary for the control processing of the control unit 4 such as data on notification conditions for each detection target gas with respect to the detection result and data on voice messages output from the notification unit 2. The storage unit 5 includes a non-volatile memory and the like, and is configured to store various information generated by the operation of the alarm device 100 in a rewritable manner. 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 can be either or both of a battery type and an external power type. 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 socket.

(Detailed configuration of control unit)
The control unit 4 is configured to perform control for notifying the user of information related to the operation and 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 that is notified by a voice message includes notification of the initial operation of the alarm device 100, notification of alarm output and alarm suspension, notification of the inspection result of the alarm device 100, and monitoring operation in the installation environment. Start alarm, past alarm output history notification, alarm device 100 error notification, alarm device 100 expiration date notification, and the like.

(Initial operation)
As shown in FIG. 3, the control unit 4 controls the alarm device body 10 to perform an initial operation when the alarm device body 10 is turned on, and notifies an initial operation message 41 related to the execution of the initial operation. 2 is configured to perform control to be output. FIG. 3 shows the flow of operation of the alarm device 100 as time elapses from when the power is turned on, and the horizontal axis indicates time. When the power is turned on, for example, when the power plug of the power supply unit 6 is connected to an external power source, but when the alarm main body 10 is provided with a power switch, the power is input by the power switch. It is.

  The control unit 4 performs an initial operation for a first time t1 from when the alarm device body 10 is powered on. Although 1st time t1 is not specifically limited, For example, it is 30 seconds.

  The initial operation of the alarm device body 10 is performed in order for the alarm device 100 to start a normal monitoring operation (an operation for monitoring whether or not the installation environment satisfies the notification condition based on the detection result of the detection unit 1). Is the action. 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 hundred degrees Celsius) by supplying current, a transient state exists immediately after the power is turned on until the sensor output signal is stabilized. During the first time t1, the control unit 4 energizes each sensor as an initial operation to stabilize the output signal of the sensor. The control unit 4 performs control so that notification based on the detection result of the detection unit 1 is not performed during the first time t1.

  The initial operation of the alarm device body 10 includes an inspection operation of the alarm device body 10. The control unit 4 checks the current and voltage to detect abnormality of the detection unit 1 (gas sensor 11 and CO sensor 12), abnormality of temperature thermistor (not shown), notification unit 2 (speaker 21, lamp 22 and signal output). Check the abnormality of the unit 23) and the operation unit 3. In addition, the control unit 4 accesses the storage unit 5 to check whether there is a data error in the storage unit 5.

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

  As an example of notification by the lamp 22, the control unit 4 blinks the green lamp 22. The second time t2 may be a time that allows the user to recognize the notification by the lamp 22, and can be a time 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 includes information related to the execution of the initial operation. The initial operation message 41 only needs to be able to inform the user that the alarm device 100 is performing some operation when the power is turned on, and does not necessarily need to notify 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 stops blinking”.

  In the present embodiment, the control unit 4 notifies the inspection result based on the inspection operation by a voice message when the first time t1 has elapsed after the power is turned on. 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 monitoring unit 1 performs a monitoring operation. Is further output.

  The inspection result can 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 broken. Please contact your dealer”, Expiration date: “5 years have passed since installation”.

  When the inspection result is normal, the control unit 4 causes the notification unit 2 to output a monitoring execution message 43 in addition to the inspection result message 42. The monitoring execution message 43 includes, for example, a message “watch over the safety of living”. Therefore, when the inspection result is normal, a voice message “alarm is normal. Thus, the control unit 4 notifies the user in the form of a voice message that the device is operating normally and starts a normal monitoring operation.

  In addition, the control part 4 performs the inspection operation | movement of the alarming device main body 10 according to the input to the operation part 3 after completion | finish of initial stage operation | movement (after progress of 1st 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 for inputting (pressing) within a predetermined time (for example, 1 second) and a long press operation for continuing input for a predetermined time (for example, 3 seconds) longer than the short press operation.

  When a 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. When the long press operation is input after the end of the initial operation, the control unit 4 controls the test operation to perform test notification (lighting or blinking) of each lamp 22 and test output of notification sound at the time of various alarm outputs. To implement. The control unit 4 stops the test notification of the lamp 22 and the test output of the notification sound when the operation unit 3 is continuously input for a predetermined time (for example, 10 seconds) when the long press operation is input. And cancel the test operation.

(Inspection operation)
In the present embodiment, the control unit 4 performs an inspection operation of the alarm device body 10 in response to an input (short press operation) to the operation unit 3 after the completion of the initial operation, and the same voice message as the inspection operation in the initial operation. Perform output control. 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 the three patterns) indicating the inspection result. If the inspection result is normal, the monitoring execution message 43 is output. Control to output additional.

  Moreover, the control part 4 performs control which outputs the remaining expiration date message 44 regarding the remaining period of the expiration date of the alarm device main body 10 when the inspection operation is performed. The control unit 4 counts the accumulated time in 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 expiration date message 44 as a voice. . The output remaining time limit message 44 is, for example, a message that “the expiration date is X years and Y months”, and the remaining time periods acquired for the variables X and Y are applied.

  Moreover, the control part 4 performs control which outputs the alerting | reporting history message 45 regarding the newest alerting | reporting cause among 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 notification execution history in the storage unit 5. The notification execution history 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”.

  While the failure has occurred, the control unit 4 continuously performs a notification indicating a failure caused by the lamp 22 (for example, blinking of the green lamp 22), and a notification sound indicating a failure caused by the speaker 21 ("Pippi Pippi"). ”Is out of order”) at regular intervals (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 “This is a failure, please contact the dealer, stop the alarm”, and the speaker 21 has failed. The output of the notification sound indicating is terminated. In the case of failure notification, notification sound output is not completed, but notification sound output ends, and once an operation input is performed, periodic notification sound output is not performed. 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 terminated according to the operation input. In addition, while the failure occurs, the control unit 4 only outputs a notification indicating the failure by the speaker 21 with respect to the operation input. The control unit 4 periodically makes a return determination, and if normal, ends the notification indicating the failure and returns to the normal monitoring operation.

  For this reason, the case where a failure notification history is output in the notification history message 45 is a case where a failure has occurred in the past and notification is made, and 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 a monitoring operation based on the detection result of the detection unit 1 after the initial operation of the alarm device body 10. During the monitoring operation, the control unit 4 determines whether or not the detection result of the detection unit 1 satisfies a predetermined notification condition. When the detection result satisfies the notification condition, the control unit 4 notifies the notification unit 2 (alarm output). Take control. The notification by the notification unit 2 includes lighting or blinking of the lamp 22 and output of a notification sound. The notification sound includes at least one of a predetermined buzzer sound and a voice message indicating an alarm.

  FIG. 4 shows a flow of the operation of the alarm device 100 as time passes from the start of notification, and the horizontal axis shows time. In 1st Embodiment, if the control part 4 receives the input with respect to the operation part 3 during alerting | reporting based on the detection result of the detection part 1, the temporary stop message 51 regarding alerting | reporting stop period SP will be output to the alerting | reporting part 2 (audio | voice output). ) And the control for temporarily stopping the notification sound. The temporary stop message 51 is an example of the “first voice message” in the claims.

  That is, in the alarm device 100 of the present embodiment, during the notification based on the detection result of the detection unit 1, the user operates the operation unit 3 to temporarily stop the notification sound during the predetermined notification stop period SP. And a pause message 51 is output when paused. When the control unit 4 pauses the notification sound, the control unit 4 counts (measures) the duration of the pause. Moreover, the control part 4 is comprised so that the alerting | reporting (lighting or blinking) by the lamp | ramp 22 may be continued even while the alerting sound is suspended.

  The temporary stop message 51 is not particularly limited as long as it includes information related to the notification stop period SP. In the present embodiment, the pause message 51 includes a time value set in advance as the notification stop period SP. That is, the pause message 51 includes a message about how long the notification sound is stopped, or how long the notification stop is canceled after a lapse of time. For example, the pause message 51 is a message “Stop alarm for 5 minutes”. In this case, the notification stop period SP is 5 minutes. As described above, the pause message 51 of the present embodiment includes information on the fact that the output of the notification sound is stopped (“alarm is stopped”) and the length of the notification stop period SP (“5 minutes”). Contains.

  In the present embodiment, when the pause message 51 is output when the notification sound is temporarily stopped, the time during which the pause message 51 is output is included in the notification stop period SP. In other words, when the notification sound is paused, the control unit 4 causes the notification unit 2 to output a pause message 51 instead of outputting the notification sound, and pauses the period during which the pause message 51 is output. Is controlled to be included in the notification stop period SP. “Instead of outputting the notification sound” may be rephrased as “stop outputting the notification sound”. For this reason, the notification stop period SP is counted as a time during which the output of the notification sound is actually stopped. The notification stop period SP includes a time during which sound other than the notification sound (pause message 51) is output.

  When the detection result of the detection unit 1 continues during the notification stop period SP and the notification condition is satisfied, the control unit 4 restarts the output of the notification sound when the notification stop period SP elapses. In this case, the control unit 4 is configured to perform control to continue the output without stopping the output of the notification sound with respect to the input to the operation unit 3 after the output of the notification sound is resumed. That is, in the alarm device 100, after the user temporarily stops outputting the notification sound, when the notification is resumed by continuing the state that satisfies the notification condition (case (A) in FIG. 4), The notification sound cannot be paused again (re-stop). For this reason, the control part 4 memorize | stores temporary stop acceptance information in the memory | storage part 5, when notifying a notification sound according to the input with respect to the operation part 3 (when outputting the pause message 51). The temporary stop reception information can be paraphrased as information on the number of times the temporary operation is received.

  When the output of the notification sound is resumed after the temporary stop, the control unit 4 controls the notification unit 2 to output a notification restart message 52 indicating that the notification is not stopped even if the input to the operation unit 3 is performed again. The notification resumption message 52 allows the user to grasp that the notification sound cannot be stopped even if the same operation as the first pause is performed. The notification restart message 52 is an example of the “second voice message” in the claims.

  The notification restart message 52 may be output when the output of the notification sound is temporarily stopped (when the pause message 51 is output), or may be output when the output of the notification sound after the suspension is resumed. In the present embodiment, the control unit 4 is configured to perform control to output the notification restart 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 that “alarm is resumed, alarm cannot be stopped next”. Thus, the notification restart message 52 of this embodiment restarts the output of the notification sound (“restarts the alarm”), and does not stop the notification even if the input to the operation unit 3 is performed again ( "Next time I can't stop the alarm").

  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 impossible message 53 indicating that the notification sound cannot be stopped, and continues the output of the notification sound. The stop impossible message 53 is, for example, a message that “alarm cannot be stopped”.

  If the gas concentration does not satisfy the notification condition during the notification stop period SP (the case of FIG. 4B), the output of the notification sound is not resumed after the notification stop period SP has elapsed. Also, the notification restart message 52 is not output. In this case, when an event that satisfies the notification condition occurs next, the control unit 4 can accept a temporary stop based on an input to the operation unit 3. That is, the control unit 4 is configured to reset the number of suspensions received 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, when the detection result of the detection unit 1 no longer satisfies the notification condition, the control unit 4 receives the temporary stop reception information stored in the storage unit 5 by clearing (erasing the information). Reset the count. Thus, when an event that satisfies the notification condition occurs next (see the two-dot chain line in FIG. 4), if the user inputs an operation, the notification sound is paused and the pause message 51 is output.

(Notification conditions)
Next, the details of the notification condition will be described with reference to FIG. The notification condition can be set for each detection target gas. That is, different notification conditions are set for each of the fuel gas and the CO gas. In addition, the notification condition may include a plurality of conditions depending on the concentration of the detection target gas. In the present embodiment, the notification condition includes a first condition C1 having a relatively high alarm level and a second condition C2 having a caution level in which the 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 satisfied and when the second condition is satisfied. Note that the first condition is met when the detected gas concentration exceeds the upper limit concentration of the second condition and is equal to or lower than the upper limit concentration of the first condition. The case where the second condition is satisfied is a case where the detected gas concentration exceeds the lower limit concentration of the second condition and is equal to or lower than the upper limit concentration of the second condition. Further, the control unit 4 is configured to invalidate the control of the pause of the notification sound and the output of the pause message 51 when a specific notification condition of a specific gas type is met.

<Fuel gas (city gas, LP gas)>
For the fuel gas (city gas, LP gas), the alarm condition first condition C1a and the caution level second condition C2a are set in the storage unit 5 in accordance with the gas concentration based on the detection result of the gas sensor 11. Yes. When the detection result (detected gas concentration) of the fuel gas corresponds to the first condition C1a, the control unit 4 provides notification by turning on the red lamp 22 (continuous lighting) and notification by outputting the notification sound from the speaker 21. Do each. Then, when the detection result of the fuel gas (city gas or LP gas) corresponds to the first condition C1a, the control unit 4 outputs the temporary stop message 51 and the notification sound temporarily 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 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 pause of the notification sound are not performed.

<CO gas>
For the CO gas, the alarm condition first condition C1b and the caution level second condition C2b are set in the storage unit 5 in accordance with 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 turning on the yellow lamp 22 (continuous lighting) and notification by outputting the notification sound from the speaker 21, respectively. And when the detection result of CO gas corresponds to the 1st condition C1b, the control part 4 is comprised so that even if the input with respect to the operation part 3 is received, control which continues an output, without stopping an alerting | reporting sound is performed. Has been. That is, the control unit 4 invalidates the control for performing the temporary stop of the notification sound and the output of the temporary stop message 51 when (gas type: CO gas, notification condition: first condition C1b) is satisfied.

  On the other hand, when the detection result of CO gas corresponds to the second condition C2b, the control unit 4 performs notification by blinking of the yellow lamp 22 and notification by output of the notification sound from the speaker 21, respectively. And when the detection result of CO gas corresponds to 2nd conditions C2b, the control part 4 controls the output of the temporary stop message 51 and the temporary stop of an alerting sound according to the input with respect to the operation part 3. It is configured.

(Other voice message output functions)
Next, other voice message output functions will be described. The alarm device 100 has a notification sound switching function 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 transition to the notification sound setting mode, information regarding the setting method, and current setting information. Specifically, the control unit 4 outputs a voice message “Change alarm sound. Select by pressing the switch. The current setting is Japanese” at the time of mode transition.

  During the notification sound setting mode, the control unit 4 switches the notification sound and outputs it to the notification unit 2 every time an input operation (pressing operation) to the operation unit 3 is received. There are no particular restrictions on the type of notification sound, but as an example, four types of notification sound can be selected: Japanese voice message, English voice message, Chinese voice message, and buzzer sound only voice message. Is done. For example, every time an input operation is accepted, the control unit 4 outputs a voice message indicating the type of notification sound such as “Japanese”, “Buzzer”, “English”, “Chinese”. In a state where a voice message indicating the type of notification sound to be selected is output, the control unit 4 confirms the selection of the type of notification sound when the user performs a predetermined operation (for example, long press operation of the operation unit 3). 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, caution) based on the detection result of the detection unit 1 by the set type of notification sound. Each notification sound indicates an example (alarm level of fuel gas), for example, as follows.
Japanese: “Woooo, beeping, gas is not leaking”
Buzzer sound: “Woooo, beeping beeping”
English: “Woo Woo, Pippippippi, (In English“ Does gas leak? ”)
Chinese: “Woo Woo, Pippi Pippi, (“ Does gas leak in Chinese? ”)
For the sake of convenience, “woo-woo”, “beep-beep”, etc. indicate buzzer sounds in onomatopoeia.

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

  First, when the power of the alarm device body 10 is turned on, the control unit 4 starts an initial operation and starts notification by the lamp 22 in step S1. The control unit 4 counts the 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 power-on. When the second time t2 has elapsed, the control unit 4 causes the notification unit 2 to output an initial operation message 41 in step S3. The control unit 4 repeats the determination in step S2 until the second time t2 has elapsed.

  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. When 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”, “failure”, “expired”) to the notification unit 2. Let In step S6, the control unit 4 determines whether or not the inspection result is “normal”. If the inspection result is “normal”, the control unit 4 causes the notification unit 2 to output the monitoring execution message 43 in step S7. Then, the process ends. In step S <b> 6, if the inspection result is not “normal”, the control unit 4 ends the process without outputting the monitoring execution message 43.

  As described above, the initial operation processing is performed.

(Short press inspection)
In addition, although description by a flowchart is abbreviate | omitted, when it is judged that an inspection result is normal and initial operation is complete | finished, the control part 4 starts the monitoring operation | movement based on the detection result of the detection part 1. FIG. In this state, the control unit 4 determines whether or not an input (short press operation) has been performed on the operation unit 3. If the short press operation is performed, the control unit 4 starts an inspection operation and also performs an inspection result notification process (FIG. 3). See).

  In the inspection result notification process, the control unit 4 performs the processes 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, causes the notification unit 2 to output the remaining expiration date message 44, and notifies the notification history message 45 based on the notification execution history stored in the storage unit 5. Let the part 2 output.

(Notification operation)
Next, with reference to FIG. 7, the notification operation and the notification sound pause process during the monitoring operation 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 or not the detection result of the detection unit 1 corresponds to any of the notification conditions (first condition C1 and second condition C2). The control unit 4 advances the process to step S12 when any one of the notification conditions is satisfied, and advances the process to step S23 when none of the notification conditions is satisfied.

  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 paused, and advances the process to step S19 when paused.

  In step S <b> 13, the control unit 4 determines whether an operation input to the operation unit 3 has been accepted. When the operation input is not received, the control unit 4 advances the process to step S14, and in step S14, outputs a notification sound according to the notification condition (first condition, second condition) corresponding to the detection result. If the notification sound is being output, the control unit 4 continues the output. When the control unit 4 determines that there is an operation input in step S13, the control unit 4 advances the process to step S15.

  In step S15, the control unit 4 determines whether or not the notification sound can be paused. That is, when the detection result of the detection unit 1 corresponds to the first condition C1b of CO in which the temporary stop is invalid, the control unit 4 determines that the temporary stop is impossible. Even when the second condition C2b for CO that can be paused or the first condition C1a for fuel gas is applicable, if the suspension acceptance information is stored in the storage unit 5 (the pause of the notification sound has already been stopped). In the case where it is performed), the control unit 4 determines that the temporary stop is impossible. When it is impossible to pause the notification sound, the control unit 4 advances the process to step S14 to output the notification sound. Although simplified in FIG. 7, when the process of step S <b> 14 is performed via step S <b> 15, unlike the case where the process does not go through step S <b> 15, the control unit 4 responds to the user's operation input with the message 53 4) is output to the notification unit 2 and the output of the notification sound is continued.

  When the notification sound can be paused, the control unit 4 temporarily stops outputting the notification sound and starts counting the notification stop period SP in step S16. In step S17, the control unit 4 outputs a temporary stop message 51. In step S18, the control unit 4 stores the temporary stop acceptance information in the storage unit 5. Thereafter, the process ends.

  On the other hand, if 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 advances the process to step S19, and the notification stop period SP is set. Judge whether or not it has passed. When the notification stop period SP has not elapsed, the control unit 4 advances the process to step S20 and continues the output stop of the notification sound. When the notification stop period SP elapses, the control unit 4 causes the notification restart message 52 to be output to the notification unit 2 in step S21, releases the temporary stop of the notification sound in step S22, and ends the process.

  Moreover, when the detection result of the detection part 1 does not correspond to any alerting | reporting conditions in step S11, the control part 4 resets the suspension reception information memorize | stored in the memory | storage part 5 in step S23. And in step S20, the control part 4 will stop a notification sound if it is alerting | reporting, and if it is not alert | reporting, the state which stopped the alerting sound will be continued as it is, and a process will be complete | finished.

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

  In the present embodiment, as described above, when the user performs an input operation on the operation unit 3 to pause the notification sound, the notification stop based on the user input operation is stopped by the pause message 51 that is output. It is possible to inform the user that the notification stop period SP is a temporary stop, not an indefinite stop. In addition, since the pause message 51 can be output at the timing of starting the pause of the notification sound, when the user stops the notification, the stop of the notification is temporary and the stop state is released later. The operation of the alarm device 100 can be notified in advance. Thereby, a user can grasp | ascertain appropriately the operation | movement of the alarm device 100 with respect to the operation input at the time of an alarm. As a result, even when the output of the notification sound is resumed when the suspension of the notification sound is canceled, it is avoided to give the user the impression that an unexpected operation has been suddenly performed for the user. it can.

  Further, in the present embodiment, as described above, the control unit 4 performs control to continue the output without stopping the output of the notification sound for the input to the operation unit 3 after the output of the notification sound is resumed. It is comprised and the control which makes the alerting | reporting part 2 output the alerting | reporting restart message 52 is performed. As a result, when the notification state has not been resolved even after the notification stop period SP has elapsed, the notification sound is not temporarily stopped even if the user inputs an operation, so that the user and the surrounding human beings can be more careful. Can be urged. The notification restart message 52 allows the user to grasp that the notification cannot be paused when the notification is resumed. Therefore, even when the control for invalidating the restart of the notification sound is performed, the operation of the alarm device 100 in response to the operation input is performed. The user can be appropriately grasped.

  In the present embodiment, as described above, the control unit 4 performs control to output the notification restart message 52 when the output of the notification sound is resumed after the notification stop period SP has elapsed. As a result, the notification restart message 52 can be output only when necessary, so that the user can more appropriately recognize that the temporary suspension is not accepted.

  In the present embodiment, as described above, the temporary stop message 51 includes a time value (“5 minutes”) preset as the notification stop period SP. Thereby, the user can be made to correctly grasp information on when the notification is resumed.

  In the present embodiment, as described above, when the control unit 4 performs a temporary stop, the control unit 4 causes the notification unit 2 to output the temporary stop message 51 instead of outputting the notification sound, and outputs the temporary stop message 51. Is controlled to be included in the notification stop period SP for temporarily stopping. Thereby, since the pause message 51 is output instead of the output of the notification sound, the contents of the pause message 51 can be easily conveyed to the user. In this case, while the pause message 51 is being output, the notification sound has not already been output, so by adding the period during which the pause message 51 is being output to the notification stop period SP. The suspension control can be performed without giving the user a sense of incongruity about the length of the notification suspension period SP.

  Further, in the present embodiment, as described above, when the detection result of the detection unit 1 does not satisfy the notification condition during the notification stop period SP, the control unit 4 temporarily stops based on the input to the operation unit 3. It is configured to reset the number of times of acceptance. Thereby, since the number of times of accepting the pause is reset once the notification condition is not satisfied, the user can perform a pause operation for the notification based on the notification cause newly generated after the notification sound is temporarily stopped. Can be.

  In the present embodiment, as described above, when the detection result of the fuel gas (city gas or LP gas) corresponds to the first condition C1a, the control unit 4 temporarily responds to the input to the operation unit 3. The stop message 51 is output and temporarily stopped. When the detection result of the CO gas (carbon monoxide gas) corresponds to the first condition C1b, the notification sound is stopped even if the input to the operation unit 3 is accepted. It is comprised so that control which continues output may be performed. Thereby, with respect to city gas or LP gas, priority can be given to the user's intention, and output of the pause message 51 and pause control can be performed. On the other hand, for carbon monoxide gas with high risk, even if an input to the operation unit 3 is accepted, control is performed so that the output is continued without stopping the alarm sound. Can be encouraged.

  Further, in the present embodiment, as described above, when the detection result of the CO gas (carbon monoxide gas) corresponds to the second condition C2b, the control unit 4 temporarily responds to the input to the operation unit 3. The stop message 51 is output and the suspension is controlled. As a result, even if carbon monoxide gas is detected, priority is given to the user's intention by controlling the suspension message 51 and outputting the suspension message 51 while the detected gas concentration is low and the second condition C2b is met. Operation (pause of notification sound) can be performed.

The embodiment disclosed this time should be considered as illustrative in all points and not restrictive. The scope of the present invention is shown not by the above description of the embodiment but by the scope of claims for patent, and further includes all modifications (modifications) within the meaning and scope equivalent to the scope of claims for patent.

  For example, in the above embodiment, an example in which the notification restart message 52 is output to the notification unit 2 has been described, but the present invention is not limited to this. In the present invention, the notification restart message 52 need not be output.

  In the above-described embodiment, the output of the notification sound is resumed without stopping the output of the notification sound with respect to the input to the operation unit 3 after the output of the notification sound is resumed. Is not limited to this. In the present invention, the notification sound may be paused by accepting a pause operation input even after the output of the notification sound is resumed. In addition, the number of times of accepting a pause operation input may be a predetermined number of times instead of one, and the pause process according to the operation input may be performed only a predetermined number of times.

  In the above embodiment, the example in which the period during which the temporary stop message 51 is output is included in the notification stop period SP has been shown, but the present invention is not limited to this. In the present invention, the period during which the temporary stop message 51 is output need not be included in the notification stop period SP.

  Moreover, in the said embodiment, when the detection result of the detection part 1 stops satisfy | filling alerting | reporting conditions during alerting | reporting stop period SP, the example which resets the acceptance count of temporary stop was shown, but this invention is limited to this. I can't. In the present invention, it is not necessary to reset the number of times the suspension is accepted.

  Moreover, in the said embodiment, when the detection result of CO gas corresponds to the 1st condition C1b, even if the input with respect to the operation part 3 is received, an alerting | reporting sound is output without stopping (a process of pause is invalidated). ) An example is shown, but the present invention is not limited to this. In the present invention, the notification sound may be temporarily stopped even when the detection result of the CO gas corresponds to the first condition C1b.

  Moreover, in the said embodiment, when the detection result of CO gas corresponds to 2nd condition C2b, and when the detection result of fuel gas (city gas or LP gas) corresponds to 1st condition C1, input operation is carried out. Although the example of performing the process of pausing the corresponding notification sound has been shown, the present invention is not limited to this. In the present invention, in these cases, the notification sound may be output without being stopped even if an input is received (the pause process is invalidated).

  In the above embodiment, the example in which the initial operation message 41 is output after the second time t2 has elapsed after the power is turned on has been described, 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, in the said embodiment, although the example which performs the test | inspection operation | movement of the alarm main body 10 was shown as initial stage operation | movement, 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.

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

  In the above embodiment, after the initial operation is completed, the alarm device body 10 is inspected according to an input (short press operation) to the operation unit 3, and the control unit 4 has the same sound as the inspection operation in the initial operation. Although an example of performing message output control has been shown, the present invention is not limited to this. In the present invention, a voice message different from the inspection operation in the initial operation may be output during the inspection operation by the short press operation.

  In the above embodiment, the input operation to the operation unit 3 is classified into the short press operation and the long press operation, and the example in which the inspection operation of the alarm device body 10 is performed according to the short press operation is shown. The invention is not limited to this. In the present invention, the inspection operation of the alarm main body 10 may be performed in accordance with the long press operation. Further, the alarm device body 10 may be inspected when there is an input to the operation unit 3 without distinguishing between the short press operation and the long press operation.

  Moreover, in the said embodiment, when the inspection operation was performed according to the operation input to the operation part 3, the example which outputs the remaining term message 44 regarding the remaining period of the expiration date of the alarm device main body 10 was shown. The invention is not limited to this. In the present invention, the remaining deadline message 44 need 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 performs processing in order along the processing flow. However, for example, the processing operation of the control unit is performed on an event basis. You may perform by the event drive type (event driven type) process which performs a process. In this case, it may be performed by a complete event drive type or a combination of event drive and flow drive.

  The specific examples of the contents of the various voice messages described in the above embodiment are merely examples, and are not limited to the contents described in the above embodiment. Any voice message may be different from the content described in the above embodiment.

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

  In addition, the specific examples of the various times exemplified in the above embodiment (the first time t1, the second time t2, and the notification stop period SP) are merely examples, and may differ from the contents described in the above embodiment. Good.

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

  In the above embodiment, the notification (lighting or blinking) by the lamp 22 is continued even while the notification sound is paused. However, the present 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 is turned off) while the notification sound is paused.

  Moreover, although the example which outputs the stop impossibility message 53 when the input to the operation part 3 was performed was shown in the said embodiment, this invention is not limited to this. In the present invention, the alarm device 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 outputting the notification sound, the stop impossible message 53 is output, and thereafter, the alarm device is configured not to output the stop impossible message 53 at the second and subsequent inputs. May be configured. Further, whether or not to output the stop disabling message 53 is separately set according to the type of notification condition (any one of the first condition C1a, C1b, the second condition C2a, C2b) corresponding to the output of the notification sound. May be.

  As a specific example, when 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 performed. If it is performed, the stop impossible message 53 is output in step S14, and then the stop disable message 53 is not output in step S14 when the input is performed for the second time and thereafter. On the other hand, if the first condition C1a of the fuel gas (city gas or LP gas) is satisfied, the stop impossible message 53 is not output in step S14 even if an input to the operation unit 3 is accepted. Thus, the alarm device may be configured.

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

  In the above-described embodiment, an example in which the notification condition includes two stages of the first condition C1 of the alarm level and the second condition C2 of the attention level is shown, but the present invention is not limited to this. In the present invention, only one stage (only the first condition) may be set as the notification condition. In addition, three or more conditions may be set as the notification condition.
