  The control unit 2 of the alarm device 1 controls various operations of the alarm device 1 (the instruction reception unit 3, the sensor 4, and the notification unit 6). The control unit 2 includes a storage device (not shown) that stores various information, and a clock function (for example, a real-time clock).

  The instruction receiving unit 3 of the alarm device 1 receives an instruction to set various operations of the alarm device 1 or an instruction to start or stop various operations of the alarm device 1. The instruction receiving unit 3 is an operation tool (for example, an operation switch, a touch panel, or a remote controller), a wired or wireless electric communication line (for example, infrared communication, a telephone line, or NFC (Near Field Communication). ), And an instruction is received by operating the operation tool, or an instruction is received through a telecommunication line. The alarm device 1 is configured to be able to set various operations or start or stop various operations according to the instruction reception mode of the instruction reception unit 3.

  The sensor 4 of the alarm device 1 detects a predetermined detection target. The sensor 4 includes a first sensor 41 and a second sensor 42.

  The first sensor 41 of the sensor 4 of the alarm device 1 is different in detection target from the second sensor 42 and detects a change in the external environment. The first sensor 41 is, for example, a gas sensor that detects a predetermined gas to be detected such as LP gas, city gas, or CO to detect a gas leak or the like, detects smoke or flame (flame temperature), and fires. It consists of a fire sensor to detect or a security sensor to detect intrusion into buildings and the like. Hereinafter, the sensor 4 will be described based on an example in which a gas sensor is provided as the first sensor 41.

  The second sensor 42 of the sensor 4 of the alarm device 1 has a detection target different from that of the first sensor 41, and has a lower urgency level affecting the human body than the first sensor 41 as a detection target. The second sensor 42 is constituted by a sensor whose detection target is at least one of temperature, humidity, and temperature / humidity. The second sensor 42 is composed of, for example, a temperature sensor, a humidity sensor, or a temperature / humidity sensor, and detects the heat and dryness around the alarm device 1. Hereinafter, the sensor 4 will be described based on an example in which a temperature / humidity sensor is provided as the second sensor 42.

The alarm unit 1 of the alarm device 1 includes a speaker and a lamp, and emits sound from the speaker, the lamp is turned on or off, or externally (for example, a management server, a security company, a building, or the like via a telecommunication line). The content detected by the sensor 4 or the state of the alarm device 1 is notified by communicating with a property management company or a portable information terminal.
The notification unit 6 notifies when the first sensor 41 of the sensor 4 detects a gas to be detected having a predetermined concentration, and when the second sensor 42 detects a predetermined temperature, a predetermined humidity, or a predetermined temperature and humidity. (Alarm). When the control unit 2 determines that the value (gas concentration value, temperature, humidity, temperature, humidity, etc.) detected by the sensor 4 is equal to or greater than a predetermined value (predetermined threshold), the notification unit 6 Inform.

  The notification unit 6 of the alarm device 1 may include a screen such as a liquid crystal instead of the lamp, and may be configured to notify the content detected by the sensor 4 or the state of the alarm device 1. Moreover, the alerting | reporting part 6 can also be set as the structure alert | reported by communicating outside (for example, a management server, a security company, a building management company, or a portable information terminal etc.) via an electric communication line.

  When the alarm unit 1 does not perform the notification operation, “the first sensor 41 of the sensor 4 detects the gas to be detected having a predetermined concentration, or the second sensor 42 has a predetermined temperature. , A function of notifying the notification unit 6 when a predetermined humidity or a predetermined temperature and humidity is detected (hereinafter referred to as “risk notification function of the notification unit 6”) is configured to be able to be stopped. In the alarm device 1, when the instruction receiving unit 3 receives an instruction (stop instruction) to stop the danger notification function of the notification unit 6 when the notification unit 6 does not perform the notification operation, the danger of the notification unit 6 is received. A setting for stopping the notification function (not notified by the notification unit 6) is performed.

  Next, the operation | movement which stops the danger alerting | reporting function of the alerting | reporting part 6 in the alarm device 1 is demonstrated using FIG.

As shown in FIG. 2, the alarm device 1 stops the danger notification function of the notification unit 6 when the operation of the notification unit 6 is not performed and the danger notification function of the notification unit 6 is not stopped. The control unit 2 determines whether or not the instruction receiving unit 3 has received an instruction to perform (step S11).
When the control unit 2 determines that the instruction receiving unit 3 has received an instruction to stop the danger notification function of the notification unit 6, the process proceeds to step S12.
If the control unit 2 does not determine that the instruction receiving unit 3 has received an instruction to stop the danger notification function of the notification unit 6, step S11 is repeated.

Next, in the alarm device 1, the control unit 2 stops the danger notification function of the notification unit 6 (step S12).
At this time, the notification unit 6 may notify the fact that the danger notification function of the notification unit 6 is stopped by a lamp, voice, or the like.
The operation | movement which stops the danger alerting | reporting function of the alerting | reporting part 6 in the alarm device 1 as mentioned above is performed.

As described above, the alarm device 1 configured to be able to stop the danger notification function of the notification unit 6 stops the danger notification function of the notification unit 6 when it is unnecessary, such as when it is absent, It can prevent that the alerting | reporting part 6 alert | reports that it is detection gas, predetermined | prescribed temperature, predetermined | prescribed humidity, or predetermined | prescribed temperature / humidity.
Therefore, the alarm device 1 suppresses power consumption when the notification unit 6 notifies that the gas to be detected has a predetermined concentration, a predetermined temperature, a predetermined humidity, or a predetermined temperature and humidity when it is unnecessary. Can do. Further, the alarm device 1 prevents the annoyance caused by the notification unit 6 frequently reporting that the gas to be detected has a predetermined concentration, a predetermined temperature, a predetermined humidity, or a predetermined temperature and humidity when it is unnecessary. can do.

As described above, in the alarm device 1 configured to be able to stop the notification function of the notification unit 6 when the instruction reception unit 3 receives an instruction (stop instruction), the instruction reception unit 3 receives the instruction. The notification function of the notification unit 6 can be stopped to prevent the notification unit 6 from reporting when it is unnecessary, such as when it is absent.
Therefore, the alarm device 1 can suppress power consumption due to notification by the notification unit 6 when it is unnecessary, and can prevent troublesomeness caused by notification by the notification unit 6 when unnecessary. .

  As described above, in the alarm device 1, the instruction receiving unit 3 accepts the instruction so that the function of the notification of the notification unit 6 can be stopped. Can be prevented from being stopped.

  As described above, the alarm device 1 is configured to be capable of stopping the function of the notification unit 6 when the operation of notification by the notification unit 6 is not performed. The notification function of the notification unit 6 can be stopped only when necessary, such as when the user is absent, not when the danger is being performed.

In the alarm device 1, at least one of the function of notifying based on the first sensor 41 and the function of notifying based on the second sensor 42 when the instruction receiving unit 3 receives the instruction (stop instruction) It can also be configured to be able to stop without any limitation. A notification function that stops without a time limit when the instruction reception unit 3 receives an instruction is set in advance.
With this configuration, when the instruction receiving unit 3 receives an instruction (stop instruction), the function of informing based on the first sensor 41 or the function of informing based on the second sensor 42 is intended. Without being stopped. In addition, since at least one of the function to be notified based on the first sensor 41 and the function to be notified based on the second sensor 42 is stopped without time limitation, the stopped notification function is unintentionally restored. It is possible to avoid being in a state of being.

In the alarm device 1, the danger notification function of the notification unit 6 that can be stopped is a function that notifies when the second sensor 42 of the sensor 4 detects a predetermined temperature, a predetermined humidity, or a predetermined temperature and humidity. You can also.
By configuring in this way, the second sensor 42 has a predetermined temperature and a predetermined humidity without stopping the danger notification function of the notification unit 6 when the first sensor 41 of the sensor 4 detects the gas to be detected. Or the function which the alerting | reporting part 6 alert | reports when predetermined temperature / humidity is detected can be stopped.
Therefore, in the alarm device 1, even if the sensor 4 has a predetermined temperature, a predetermined humidity, or a function in which the notification unit 6 notifies when a predetermined temperature and humidity are detected, the notification urgent level is high. The notification by the notification unit 6 when a relatively high gas to be detected is detected can be reliably performed.

In the alarm device 1, the first sensor 41 of the sensor 4 can be configured to detect the gas to be detected when the danger notification function of the notification unit 6 is stopped.
By configuring in this way, in the alarm device 1, even when the danger notification function of the notification unit 6 is stopped, the first sensor 41 of the sensor 4 detects the gas to be detected having a predetermined concentration, It is possible to grasp the concentration state of the gas to be detected around the alarm device 1 when the danger notification function of the notification unit 6 is stopped.

In the alarm device 1, the second sensor 42 of the sensor 4 can be configured to detect temperature, humidity, or temperature / humidity when the danger notification function of the notification unit 6 is stopped.
By configuring in this way, in the alarm device 1, even when the danger notification function of the notification unit 6 is stopped, the second sensor 42 of the sensor 4 detects the temperature or humidity, and the notification unit 6 It is possible to grasp the temperature, humidity, or temperature / humidity state when the danger notification function is stopped.

The alarm device 1 has the risk notification function of the notification unit 6 after a predetermined time has elapsed (for example, after 3 hours have elapsed) or every predetermined interval (for example, every hour) after the danger notification function of the notification unit 6 has stopped. It can also be set as the structure which the alerting | reporting part 6 alert | reports that it is stopping.
With this configuration, the alarm device 1 notifies (prompts) that the danger notification function of the notification unit 6 is stopped while the danger notification function of the notification unit 6 is stopped. It is possible to prevent the setting for returning the danger notification function from being forgotten.

The alarm device 1 can be configured to be able to notify whether or not the danger notification function of the notification unit 6 is stopped. For example, when the danger notification function of the notification unit 6 is stopped, a predetermined lamp of the notification unit 6 blinks, and when the danger notification function of the notification unit 6 is not stopped, the predetermined lamp of the notification unit 6 is turned off. The configuration.
By comprising in this way, it can be grasped | ascertained easily about whether the danger alerting | reporting function of the alerting | reporting part 6 has stopped.

The notification unit 6 of the alarm device 1 includes a gas lamp that notifies when the first sensor 41 of the sensor 4 detects a gas to be detected having a predetermined concentration, and the second sensor 42 of the sensor 4 has a predetermined temperature and a predetermined humidity. Alternatively, a temperature / humidity lamp for notifying when a predetermined temperature / humidity is detected may be provided.
At this time, the alarm unit 1 notifies that the first sensor 41 of the sensor 4 has detected the gas to be detected having a predetermined concentration while the danger notification function of the notification unit 6 based on the second sensor 42 is stopped. When notifying, the temperature / humidity lamp is turned on in addition to the gas lamp of the notifying unit 6 (for example, the gas lamp and the temperature / humidity lamp are alternately blinked, or the gas lamp and the temperature / humidity lamp are turned on simultaneously). It can also be configured.

The notification unit 6 of the alarm device 1 notifies in a different manner between notification based on the detection of the first sensor 41 of the sensor 4 and notification based on the second sensor 42.
By configuring in this way, the alarm device 1 can grasp the state of the detection target detected by the sensor 4 when the notification unit 6 notifies.
In addition to such a configuration, the alarm device 1 is different when the second sensor 42 detects a predetermined temperature, when it detects a predetermined humidity, or when it detects a predetermined temperature and humidity. It can also be set as the structure alert | reported in an aspect.

Based on the temperature and humidity detected by the second sensor 42 of the sensor 4, the alarm device 1 can be notified by the notification unit 6 at a plurality of levels according to the degree of warning of heat (risk of heat stroke) or dryness. It can also be. For example, the alarm device 1 is configured so that the notification unit 6 can be notified in four stages according to the alertness of the heat index (WBGT (Wet Bull Globe Temperature)), and in three stages according to the alertness of the dryness index. The notification unit 6 is configured to be capable of notification.
By comprising in this way, since the alerting | reporting part 6 alert | reports in several levels according to each alertness degree of heat or a dryness, it can grasp | ascertain the finer state regarding a heat | fever or a dryness.

The alarm device 1 can also be configured to be able to set a stop range of the danger notification function of the notification unit 6 that notifies when the second sensor 42 of the sensor 4 detects for each notification regarding heat or notification regarding drying. . For example, the alarm device 1 may notify the notification unit 6 at the first stage (lowest level of alertness) among a plurality of levels regarding the heat, and at all levels regarding drying. The range in which the danger notification function of the notification unit 6 is stopped can be set so that the notification unit 6 does not notify (stops the notification of the notification unit 6 regarding drying). The range in which the danger notification function of the notification unit 6 stops is set to an arbitrary value in advance via the instruction receiving unit 3.
By being configured in this manner, for each notification regarding heat or notification regarding drying, the range in which the danger notification function of the notification unit 6 stops is set to an arbitrary one, and the user's state (health state, age, etc.) ) Can be informed about heat and dryness.

  The alarm device 1 determines the stop time of the danger notification function of the notification unit 6 and the return of the danger notification function of the notification unit 6 depending on the mode of stop instruction received by the instruction reception unit 3 (for example, the medium to be instructed and the content of the instruction). It is configured to be able to set whether or not. The alarm device 1 stops the danger notification function of the notification unit 6 for a predetermined time when the instruction receiving unit 3 receives the instruction, and also stops the danger notification function of the notification unit 6 without time limit.

For example, the alarm device 1 stops the danger notification function of the notification unit 6 for 24 hours by instructing the instruction receiving unit 3 with an operation tool in the absence of a short period such as 24 hours, and the danger notification of the notification unit 6 It is configured such that the danger notification function of the notification unit 6 automatically returns after 24 hours have elapsed since the function was stopped.
Further, for example, in the case of a long absence such as several days (for example, 3 days), the alarm device 1 notifies the user by instructing a slightly longer period than when the instruction receiving unit 3 is stopped for 24 hours by the operation tool. The risk notification function of the notification unit 6 is automatically returned after three days have elapsed since the danger notification function of the notification unit 6 is stopped for three days and the risk notification function of the notification unit 6 is stopped.
Also, for example, when the alarm device 1 stops the danger notification function of the notification unit 6 without time limitation, the alarm device 1 notifies the user by instructing a longer period than when the instruction receiving unit 3 is stopped for three days with the operation tool. The danger notification function of the notification unit 6 is configured not to return unless the danger notification function of the unit 6 is stopped and the instruction receiving unit 3 is not operated by the operation tool.
As an example of the operation of the instruction receiving unit 3 by the operation tool, there is a pressing operation of an operation switch. In such an example, the stop period of the danger notification function of the notification unit 6 can be selected and set by changing the time (pressing time) of the pressing operation of the operation switch.

  In the above example, the stop period of the danger notification function of the notification unit 6 is changed depending on the content of the instruction to the instruction reception unit 3, but for example, when instructed by an IC card, it is stopped for 24 hours, when instructed by a mobile terminal May be stopped for 3 days, or the stop period of the danger notification function of the notification unit 6 may be changed by a medium instructed to the instruction reception unit 3 so that the operation is stopped with no time limit when instructed by the operation tool. Good.

  As described above, in the alarm device 1 configured so that the stop time of the danger notification function of the notification unit 6 can be set according to the mode of the stop instruction received by the instruction reception unit 3, the instruction reception unit 3 receives the stop instruction. Thus, the stop time of the danger notification function of the notification unit 6 can be set to an arbitrary time.

  As described above, the alarm notification function of the notification unit 6 is stopped for a predetermined time according to the mode of the stop instruction received by the instruction reception unit 3. In the alarm device 1, when the instruction reception unit 3 receives the stop instruction, the notification unit 6 The stoppage time of the danger notification function can be set to an arbitrary time.

  As described above, the alarm notification function of the notification unit 6 is stopped without a time limit according to the mode of the stop instruction received by the instruction reception unit 3. In the alarm device 1, the notification is received when the instruction reception unit 3 receives the stop instruction. It is possible to make a setting for stopping the danger notification function of the unit 6 without time limit.

The alarm device 1 is configured such that the inspection operation of the alarm device 1 can be performed when the instruction receiving unit 3 receives an instruction when the notification operation of the notification unit 6 is not performed.
The alarm unit 1 is configured to notify the alarm unit 6 when the inspection operation of the alarm unit 1 is executed when the danger notification function of the notification unit 6 is stopped and when the danger notification function of the notification unit 6 is restored. It can be set as the structure from which the aspect which alert | reports or the inspection content of the alarm device 1 differs. For example, the alarm device 1 has a configuration in which the lamp lighting mode of the notification unit 6 is different between when the danger notification function of the notification unit 6 is stopped and when the danger notification function of the notification unit 6 is restored. When the danger notification function of the notification unit 6 is stopped, a notification regarding normal inspection that the danger notification function of the notification unit 6 is stopped (notification regarding inspection when the danger notification function of the notification unit 6 is restored). It can be set as the structure which alert | reports together.

  The alarm device 1 can be configured to be able to notify whether or not the danger notification function of the notification unit 6 is stopped by being operated in a mode different from the operation for starting the inspection operation. For example, the alarm device 1 starts an inspection operation when the operation switch (instruction receiving unit 3) is pressed and held for 3 seconds or longer, and notifies when the operation switch is pressed for 0.5 seconds or more and less than 2 seconds. It notifies about whether the danger notification function of the part 6 has stopped.

  With this configuration, even if the danger notification function of the notification unit 6 is configured to be able to be stopped, the start of the inspection operation and whether the danger notification function of the notification unit 6 is stopped are notified. The operation can be executed with a simple operation. Further, the operation tool for starting the inspection operation and the operation tool for performing the notification operation as to whether or not the danger notification function of the notification unit 6 is stopped can be configured with a common operation tool, A relatively simple configuration can be obtained.

When the second sensor 42 of the sensor 4 of the alarm device 1 is composed of a temperature sensor and a humidity sensor, either the temperature sensor of the second sensor 42 or the humidity sensor of the second sensor 42 is used. When the notification unit 6 is not performing the notification operation based on the detection, the danger notification function of the notification unit 6 based on the detection of the part of the sensors may be stopped. For example, if the operation of the notification unit 6 based on the temperature sensor of the second sensor 42 is not performed, the operation of the notification unit 6 based on the humidity sensor of the second sensor 42 may be performed. The notification function of the notification unit 6 based on the temperature sensor of the second sensor 42 can be stopped.
In the alarm device 1, only the notification function based on the first sensor 41, only the notification function based on the second sensor 42, or the notification function based on the first sensor 41 and the second according to the required specifications. Any of the notification functions based on the sensor 42 can be configured to be stoppable.

In addition to stopping the danger notification function of the notification unit 6, the alarm device 1 can temporarily stop the notification function (notification operation of the notification unit 6) at the time of notification by the notification unit 6.
Specifically, the alarm device 1 receives the instruction by the instruction receiving unit 3 when the notification unit 6 notifies that the predetermined temperature has been detected by the second sensor 42 of the sensor 4, thereby The notification operation of the notification unit 6 to the effect that the sensor 42 has detected a predetermined temperature can be stopped for a predetermined time (for example, 30 minutes).
The alarm device 1 is configured such that when the notification unit 6 notifies that the gas to be detected having a predetermined concentration is detected by the first sensor 41 of the sensor 4, the instruction receiving unit 3 receives the instruction, whereby the first sensor It is comprised so that the alerting | reporting operation | movement of the alerting | reporting part 6 to the effect that the to-be-detected gas of predetermined density | concentration is detected by 41 can be stopped for predetermined time (for example, 3 minutes).
The stop time of the danger notification function of the notification unit 6 may be the same for the notification based on the first sensor 41 and the notification based on the second sensor 42, or may be different. In the case where the stop time of the danger notification function of the notification unit 6 is different from the notification based on the first sensor 41 and the notification based on the second sensor 42, for example, the notification urgent level is higher (first sensor 41). ) Notification function stop time can be set short, and the notification function stop time of the lower emergency level (second sensor 42) can be set longer.

  The alarm device 1 is configured such that the stopped danger notification function of the notification unit 6 can be restored. In the alarm device 1, the instruction receiving unit 3 receives an instruction (return instruction) for returning the danger notification function of the notification unit 6, a predetermined time has elapsed since the danger notification function of the notification unit 6 stopped, or a notification The risk notification function of the notification unit 6 is satisfied by satisfying a predetermined condition (hereinafter referred to as “recovery condition”) for returning the risk notification function of the notification unit 6 before the predetermined time has elapsed since the danger notification function of the unit 6 is stopped. Is set to restore.

  The return condition of the alarm device 1 is a condition other than the condition based on the instruction receiving unit 3 receiving the return instruction and the condition based on a predetermined time elapsed after the danger notification function of the notification unit 6 is stopped. In a state in which the danger notification function of the notification unit 6 is stopped, a preset time (for example, 18:00 every day) is reached, and / or the temperature, humidity detected by the second sensor 42 of the sensor 4, Alternatively, the condition is set in advance when the instruction receiving unit 3 receives an instruction as a condition based on, for example, that at least one of the temperature and humidity is in a state where the alert level is high enough to return the danger notification function of the notification unit 6.

  Here, at least one of the temperature, humidity, and temperature / humidity detected by the second sensor 42 of the sensor 4 is in a state where the alert level is high enough to require the return of the danger notification function of the notification unit 6, for example, It is detected that the second sensor 42 of the sensor 4 has a predetermined temperature, a predetermined humidity, or a predetermined temperature and humidity continuously for a predetermined time (for example, one hour) with the danger notification function of the notification unit 6 stopped. Or when the value detected by the second sensor 42 suddenly exceeds a predetermined threshold (when the amount of increase in the heat index detected by the second sensor 42 per unit time is greater than or equal to a predetermined amount), etc. Is done.

  Next, the operation | movement which the danger alerting | reporting function of the alerting | reporting part 6 in the alarm device 1 resets is demonstrated using FIG.

As shown in FIG. 3, in the alarm device 1, the control unit 2 determines whether or not a predetermined time has elapsed (a preset stop time has elapsed) since the danger notification function of the notification unit 6 has been stopped ( Step S21).
When the control unit 2 determines that a predetermined time has elapsed since the danger notification function of the notification unit 6 was stopped, the process proceeds to step S24.
If the control unit 2 does not determine that a predetermined time has elapsed since the danger notification function of the notification unit 6 was stopped, the process proceeds to step S22. In addition, when the setting which stops the danger alerting | reporting function of the alerting | reporting part 6 without the restriction | limiting of time is performed, as a case where the control part 2 does not judge that predetermined time passed since stopping the danger alerting | reporting function of the alerting | reporting part 6 The process proceeds to step S22.

Next, in the alarm device 1, in a state where the danger notification function of the notification unit 6 is stopped (before the stop time of the danger notification function of the notification unit 6 has elapsed), an instruction to return the danger notification function of the notification unit 6 (return instruction) The control unit 2 determines whether or not the instruction receiving unit 3 has received (Step S22).
When the control unit 2 determines that the instruction receiving unit 3 has received an instruction to return the danger notification function of the notification unit 6, the process proceeds to step S24.
When the control unit 2 does not determine that the instruction receiving unit 3 has received an instruction to return the danger notification function of the notification unit 6, the process proceeds to step S23.

Next, in the alarm device 1, the control unit 2 determines whether or not the return condition is satisfied (step S23).
When the control unit 2 determines that the return condition is satisfied, the process proceeds to step S24.
If the control unit 2 does not determine that the predetermined condition is satisfied, the process proceeds to step S21.

Next, in the alarm device 1, the control unit 2 returns the danger notification function of the notification unit 6 (step S24). At this time, the notification unit 6 may notify by voice or a lamp that the danger notification function of the notification unit 6 is restored.
As described above, the operation of returning the danger notification function of the notification unit 6 in the alarm device 1 is performed.
In the above description, three conditions (the instruction receiving unit 3 accepts an instruction to return the risk notification function of the notification unit 6, and the risk notification of the notification unit 6 are the conditions for the risk notification function of the notification unit 6 to return. An example in which a predetermined time has elapsed since the function stopped, and the risk notification function of the notification unit 6 satisfies the return condition before the predetermined time has elapsed since the danger notification function of the notification unit 6 stopped. However, the present invention is not limited to this, and a configuration may be adopted in which one or two or more conditions for returning the danger notification function of the notification unit 6 are restored.

  As described above, the alarm unit 1 is configured to return the danger notification function of the notification unit 6 when a predetermined time has elapsed after the danger notification function of the notification unit 6 is stopped. For example, when the predetermined time elapses after the function is stopped, the risk notification function of the notification unit 6 can be automatically restored even if the risk notification function of the notification unit 6 has been forgotten. it can.

  As described above, even when the predetermined time has not elapsed (before the danger notification function of the notification unit 6 has stopped), the instruction receiving unit 3 receives an instruction to return the risk notification function of the notification unit 6 to notify In the alarm device 1 in which the danger notification function of the unit 6 is restored, even if it is before the predetermined time has elapsed (before the stop time of the danger notification function of the notification unit 6 has elapsed), for example, when it is necessary to return home, for example, Without waiting for the progress, the instruction receiving unit 3 can return the danger notification function of the notification unit 6 by receiving the return instruction. Therefore, according to the alarm device 1, it is possible to eliminate troublesomeness caused by waiting until the danger notification function of the notification unit 6 is restored when necessary.

  As described above, when the return condition is satisfied, the alarm notification function of the notification unit 6 is restored even after a predetermined time has elapsed after the danger notification function of the notification unit 6 is stopped. Even before the elapse of time (before the elapse of the stoppage time of the danger notification function of the notification unit 6), for example, when the user needs to return home, for example, when the return condition is satisfied without waiting for the predetermined time to elapse. The danger notification function is restored. Therefore, according to the alarm device 1, the danger notification function of the notification unit 6 has not been restored when necessary, and the annoyance caused by waiting for the predetermined time to elapse when the danger notification function of the notification unit 6 is restored. Can be resolved.

  The alarm device 1 notifies the danger notification of the notification unit 6 when the first sensor 41 detects a predetermined time from when the danger notification function of the notification unit 6 stops until the danger notification function of the notification unit 6 returns. The function stop time and the stop time of the danger notification function of the notification unit 6 that notifies when the second sensor 42 detects can also be configured to be set at different times. That is, the stop time of the danger notification function of the notification unit 6 that notifies when the first sensor 41 detects is different from the stop time of the danger notification function of the notification unit 6 that notifies when the second sensor 42 detects. Can be set to

By configuring in this way, for example, in a normal case, the stop time of the danger notification function of the notification unit 6 that notifies when the first sensor 41 having a relatively high degree of urgency affecting the human body is detected, It can be set shorter than the stop time of the danger notification function of the notification unit 6 that notifies when the second sensor 42 detects. For example, when it is predicted that the day is extremely hot, the first sensor 41 detects the stop time of the danger notification function of the notification unit 6 that notifies when the second sensor 42 detects it. It is possible to set a shorter time than the stop time of the danger notification function of the notification unit 6 that notifies the user.
Therefore, according to the alarm device 1, according to the surrounding state of the alarm device 1, the stop time of the danger notification function of the notification unit 6 that notifies when the first sensor 41 detects, and the second sensor 42 detects. The predetermined time from when the danger notification function of the notification unit 6 is stopped to when the danger notification function of the notification unit 6 is restored is set to a different time, depending on the stop time of the danger notification function of the notification unit 6 that is sometimes notified. Thus, convenience can be improved.

  The alarm device 1 is configured such that when the danger notification function of the notification unit 6 is restored before the danger notification function of the notification unit 6 stops and before a predetermined time (set stop time) has elapsed, the danger notification function of the notification unit 6 In the case where the danger notification function of the notification unit 6 is restored after a predetermined time has elapsed since the stop, the operation mode of the alarm device 1 (for example, the operation mode of the notification unit 6) after the danger notification function of the notification unit 6 is restored. Different configurations are possible.

In the alarm device 1, for example, when the danger notification function of the notification unit 6 is restored before a predetermined time has elapsed since the danger notification function of the notification unit 6 is stopped, the danger notification function of the notification unit 6 is determined before the predetermined time has elapsed. The notification unit 6 notifies that the alarm has returned, and when the risk notification function of the notification unit 6 returns after a predetermined time has elapsed since the danger notification function of the notification unit 6 has stopped, the notification unit 6 The notification unit 6 notifies that the danger notification function has returned.
Further, for example, when the danger notification function of the notification unit 6 is restored before the predetermined time has elapsed since the danger notification function of the notification unit 6 is stopped, a sound and a lamp indicate that the danger notification function of the notification unit 6 has returned. In the case where the notification unit 6 notifies, and the danger notification function of the notification unit 6 returns after a predetermined time has elapsed after the danger notification function of the notification unit 6 stops, the fact that the danger notification function of the notification unit 6 has returned. The notification unit 6 notifies with a lamp.
In addition, for example, when the danger notification function of the notification unit 6 is restored before a predetermined time has elapsed since the danger notification function of the notification unit 6 is stopped, the notification of the notification unit 6 is compared with a case where the notification is returned after the predetermined time has elapsed. Decrease the volume at the time.

  With this configuration, the danger notification function of the notification unit 6 can notify whether the instruction reception unit 3 has returned after receiving a return instruction before the predetermined time has elapsed or has returned after the predetermined time has elapsed. .

  In a case where the danger notification function of the notification unit 6 is restored before the predetermined time elapses and the operation mode of the alarm device 1 is different from the operation mode when the danger notification function of the notification unit 6 is restored after the elapse of the predetermined time, the notification unit 6 when the predetermined time has elapsed since the danger notification function 6 has stopped, or when a certain time has elapsed since the danger notification function of the notification unit 6 has returned, the operation mode of the alarm device 1 is changed to the danger notification of the notification unit 6. It is also possible to adopt a configuration in which the function is set to be the same as that when the function returns after a predetermined time. By comprising in this way, the operation | movement aspect of the alarm device 1 after the danger alerting | reporting function of the alerting | reporting part 6 resets always depending on whether predetermined time passed after the danger alerting | reporting function of the alerting | reporting part 6 stopped. You can prevent different things.

  The alarm unit 1 satisfies the return condition before the elapse of a predetermined time (set stop time) after the danger notification function of the notification unit 6 stops, and the notification unit 6 returns to the danger notification function of the notification unit 6. When the risk notification function of the notification unit 6 is restored after a lapse of a predetermined time from the stop of the danger notification function, and when the instruction reception unit 3 receives the return instruction before the lapse of the predetermined time, the risk notification function of the notification unit 6 is restored. Then, it can also be set as the structure from which the operation | movement aspect (for example, operation | movement aspect of the alerting | reporting part 6) of the alarm device 1 after the danger alerting | reporting function of the alerting | reporting part 6 resets is different.

In the alarm device 1, for example, when the risk notification function of the notification unit 6 is restored by satisfying the return condition before the predetermined time elapses after the danger notification function of the notification unit 6 stops, it is compared with the other cases. Thus, the volume at the time of notification by the notification unit 6 is set to be small.
Similarly to the above, when the risk notification function of the notification unit 6 is restored by satisfying the return condition before the predetermined time elapses after the danger notification function of the notification unit 6 is stopped, and in other cases, the notification unit The notification unit 6 changes the content that the danger notification function 6 returns, or the notification unit 6 notifies the fact that the danger notification function of the notification unit 6 has returned. Or notification only with a lamp).

  With this configuration, even if the danger notification function of the notification unit 6 is restored against the user's intention, it is possible to notify the user of a dangerous state while reducing discomfort to the user. It becomes.

When the risk notification function of the notification unit 6 returns after satisfying the return condition before the predetermined time elapses, and the operation mode of the alarm device 1 returns after the risk notification function of the notification unit 6 has elapsed the predetermined time or before the predetermined time elapses When the instruction receiving unit 3 is different from the operation mode when the return instruction is received and returned, when the predetermined time has elapsed after the danger notification function of the notification unit 6 stops or the danger notification function of the notification unit 6 is When a certain period of time has elapsed since the return, the operation mode of the alarm device 1 is restored when the danger notification function of the notification unit 6 returns after a predetermined time has elapsed or the instruction reception unit 3 receives a return instruction before the predetermined time has elapsed. It can also be set as the same thing as the thing at the time of doing.
By comprising in this way, whether the operation | movement aspect of the alarm device 1 after the danger alerting | reporting function of the alerting | reporting part 6 reset | restored whether the predetermined time passed after the danger alerting | reporting function of the alerting | reporting part 6 stopped, or Depending on whether or not the instruction reception unit 3 has received a return instruction before the predetermined time has elapsed since the danger notification function of the notification unit 6 has stopped, it can be prevented from always differing.

  The alarm device 1 can also be configured to return some functions of the danger notification function of the notification unit 6 when the return condition is satisfied and the danger notification function of the notification unit 6 returns. The alarm device 1 may be configured to return, for example, only the lamp function of the danger notification function of the notification unit 6 when the danger notification function of the notification unit 6 returns when the return condition is satisfied.

  If the second sensor 42 of the sensor 4 is configured to be able to detect temperature, humidity, or temperature / humidity when the danger notification function of the notification unit 6 is stopped, the alarm device 1 detects the notification unit in step S24. When the danger notification function 6 is restored, the temperature, humidity, or information about the temperature and humidity detected by the second sensor 42 of the sensor 4 while the danger notification function of the notification unit 6 is stopped can be notified by voice.

  In the alarm device 1, for example, information on the temperature, humidity, or temperature / humidity detected by the second sensor 42 of the sensor 4 while the danger notification function of the notification unit 6 is stopped (the value detected by the second sensor 42 of the sensor 4) Time etc.) is notified by a speaker. At this time, the alarm device 1 detects that the second sensor 42 of the sensor 4 is stopped during the stoppage of the danger notification function of the notification unit 6 only when the instruction reception unit 3 receives the return instruction and the danger notification function of the notification unit 6 returns. It can also be set as the structure which alert | reports the information regarding the detected temperature, humidity, or temperature / humidity by an audio | voice.

  Even if it is the structure which can stop the danger alerting | reporting function of the alerting | reporting part 6 by comprising in this way, when the danger alerting | reporting function of the alerting | reporting part 6 returns, the temperature during the stop of the danger alerting | reporting function of the alerting | reporting part 6 Alternatively, the humidity status can be notified.

In the alarm device 1, the return condition is such that at least one of the temperature, humidity, and temperature / humidity detected by the second sensor 42 of the sensor is at a high alert level so that the danger notification function of the notification unit 6 needs to be returned. If the condition is based on the temperature, the humidity detected by the second sensor 42 even if the setting for returning the danger notification function of the notification unit 6 by instructing the return to the instruction receiving unit 3 is forgotten, or When at least one of the temperature and humidity is in a state where the alert level is so high that the risk notification function of the notification unit 6 needs to be restored, the state where the danger notification function of the notification unit 6 is not restored can be solved.
Further, when the return condition is a condition based on a preset time, the setting for returning the danger notification function of the notification unit 6 by instructing the return to the instruction receiving unit 3 is forgotten. Even when the preset time is reached, the notification function of the notification unit 6 can be restored.

In the alarm device 1, as a return condition, when the danger notification function of the notification unit 6 is stopped, the condition is based on the fact that the power source (power source of the alarm device 1) is turned off and then the power source is turned on again. You can also.
By configuring in this way, it is possible to prevent the state in which the danger notification function of the notification unit 6 is stopped before the power is turned off from continuing after the power is turned on and restarted.

  When the instruction receiving unit 3 receives an instruction to stop the danger notification function of the notification unit 6, the alarm device 1 prohibits the stop of the danger notification function of the notification unit 6 (hereinafter referred to as “stop prohibition condition”). ) Is not satisfied, the danger notification function of the notification unit 6 is stopped. When the stop prohibition condition is satisfied, the danger notification function of the notification unit 6 may not be stopped.

In the alarm device 1, the stop prohibition condition is, for example, the temperature, humidity, or temperature detected by the second sensor 42 of the sensor 4 when the instruction receiving unit 3 receives an instruction to stop the danger notification function of the notification unit 6. That at least one of the humidity is in a state of a high alert level that prohibits the stop of the danger notification function of the notification unit 6, that a predetermined time has not elapsed since the latest notification unit 6 has reported, and / or As a condition based on, for example, that the instruction receiving unit 3 does not receive an instruction to stop the danger notification function of the notification unit 6, a setting is made in advance by instructing the instruction receiving unit 3 (for example, the parent in advance so that the child cannot stop). Setting).
Here, a state in which a warning level is so high that at least one of temperature, humidity, and temperature / humidity detected by the second sensor 42 of the sensor 4 prohibits the stop of the danger notification function of the notification unit 6 is within a predetermined time ( For example, when it is detected that the second sensor 42 of the sensor 4 has a predetermined temperature, a predetermined humidity, or a predetermined temperature and humidity within one hour), or the second sensor 42 of the sensor 4 It is set in advance when it is detected that the temperature is less than the threshold but is a predetermined temperature, a predetermined humidity, or a predetermined temperature and humidity.

When configured in this manner, as shown in FIG. 4, in the alarm device 1, the control unit 2 determines that the instruction receiving unit 3 has received an instruction to stop the danger notification function of the notification unit 6 in step S11. In this case, the process proceeds to step S13, and the control unit 2 determines whether or not the stop prohibition condition is satisfied (step S13).
When the control unit 2 determines that the stop prohibition condition is satisfied, the process proceeds to step S11. At this time, the notification unit 6 notifies that the instruction receiving unit 3 has received an instruction to stop the danger notification function of the notification unit 6 but does not stop the danger notification function of the notification unit 6 in order to satisfy the stop prohibition condition.
If the control unit 2 does not determine that the stop prohibition condition is satisfied, the process proceeds to step S12.

  As described above, when the instruction receiving unit 3 receives an instruction to stop the danger notification function of the notification unit 6, the alarm device 1 does not stop the danger notification function of the notification unit 6 when the stop prohibition condition is satisfied. Then, even if the instruction receiving unit 3 receives the stop instruction, if the stop prohibition condition is satisfied, the danger notification function of the notification unit 6 is not stopped, and therefore the danger notification function of the notification unit 6 satisfying the stop prohibition condition is stopped. In such a situation, it is possible to prevent the instruction receiving unit 3 from receiving a stop instruction and informing the notification unit 6 from being erroneously stopped.

In the alarm device 1, the stop prohibition condition is such that at least one of the temperature, humidity, and temperature / humidity detected by the second sensor 42 of the sensor 4 prohibits the stop of the danger notification function of the notification unit 6 so that the warning level is high. When the condition is based on the condition, the warning level is such that at least one of the temperature, humidity, and temperature / humidity detected by the second sensor 42 of the sensor 4 prohibits the stop of the danger notification function of the notification unit 6. It is possible to prevent the instruction receiving unit 3 from receiving a stop instruction and reporting the notification unit 6 from being erroneously stopped when a high level of danger is present.
When the stop prohibition condition is a condition based on the fact that a predetermined time has not elapsed since the operation notified by the latest notification unit 6, it is dangerous that the predetermined time has not elapsed since the operation notified by the latest notification unit 6 When there is a high possibility that the state is continuing, it is possible to prevent the instruction receiving unit 3 from receiving a stop indication and stopping the function of the notification unit 6 reporting.
When the stop prohibition condition is a condition based on a preset condition that the instruction receiving unit 3 does not accept an instruction to stop the danger notification function of the notification unit 6, for example, without intention by a child or the like It is possible to prevent the instruction receiving unit 3 from receiving the stop instruction and informing the notification unit 6 from being erroneously stopped.

As shown in FIG. 5, in the alarm device 1, when the control unit 2 determines that the stop prohibition condition is satisfied in step S <b> 13, the process proceeds to step S <b> 14 to stop the danger notification function of the notification unit 6. The instruction receiving unit 3 receives an instruction to stop the danger notification function of the notification unit 6 within a predetermined time (for example, within 15 seconds) after the instruction reception unit 3 has recently received the instruction to perform (the instruction reception unit 3 It can also be configured that the control unit 2 determines whether or not re-instruction reception has been performed (step S14).
The control unit has received an instruction to stop the danger notification function of the notification unit 6 within a predetermined time after the instruction reception unit 3 has recently received an instruction to stop the danger notification function of the notification unit 6. When 2 is judged, it transfers to step S12. At this time, the notification unit 6 notifies that the danger notification function of the notification unit 6 is stopped because the instruction reception unit 3 receives the stop instruction again although the stop prohibition condition is satisfied.
The control unit has received an instruction to stop the danger notification function of the notification unit 6 within a predetermined time after the instruction reception unit 3 has recently received an instruction to stop the danger notification function of the notification unit 6. When 2 does not judge, it transfers to step S11.

  As described above, when the instruction receiving unit 3 receives an instruction to stop the danger notification function of the notification unit 6 and when the stop prohibition condition is satisfied, the instruction to stop the danger notification function of the notification unit 6 within a predetermined time is issued. When the instruction receiving unit 3 receives the alarm, the alarm unit 1 stops the danger notification function. In the alarm device 1, for example, when it is unnecessary, such as when going out, even within the predetermined time even if the stop prohibition condition is satisfied. When the instruction receiving unit 3 receives the stop instruction again, the danger notification function of the notification unit 6 can be stopped.

In the above example, when the danger notification function of the notification unit 6 is stopped, the notification unit 6 does not perform notification with either a lamp or sound, but is not limited to this, and a predetermined temperature and / or predetermined humidity is detected. When the notification is made, the notification unit 6 may perform a notification operation using only the lamp.
Even in this way, it is possible to suppress the power consumption caused by the notification by the notification unit 6 and to prevent the troublesomeness caused by the voice notification when unnecessary, and to notify that it is in a dangerous state. .
