The control unit 2 includes a storage device 8 and a clock function (for example, a real time clock).

  The sensor unit 3 of the alarm device 1 detects a change in the external environment. The sensor unit 3 is a gas sensor that detects gas such as LP gas, city gas, or carbon monoxide to detect a gas leak, or a fire sensor that detects temperature or smoke to detect a fire. Configured

The notification unit 4 of the alarm device 1 is configured to be able to change the notification mode such as the type of voice, voice pattern, volume, sound pressure, or communication destination. The notification unit 4 gives notification by, for example, emitting a sound such as an alarm sound or an alarm message, and / or communicating with the outside (for example, a security company, a building management company, a fire department, a portable information terminal, etc.) Do.
The notification unit 4 issues a notification when the sensor unit 3 detects a change in the external environment. The notification unit 4 issues a notification when the control unit 2 determines that the value detected by the sensor unit 3 is equal to or greater than a predetermined value.

  The lamp unit 5 of the alarm device 1 is configured to be able to change a lighting pattern such as a lighting pattern, a color to be lit, or brightness. The lamp unit 5 is lit (flickers on) when an abnormality such as when the sensor unit 3 detects a change in the external environment. When the control unit 2 determines that the value detected by the sensor unit 3 is equal to or greater than a predetermined value, the lamp unit 5 controls that the value detected by the sensor unit 3 is not equal to or greater than the predetermined value. It lights up in a mode different from the time when the part 2 judges.

The front and back surfaces of the disc of the display unit 7 are colored in different colors (for example, the front surface is black and the back surface is green). The display unit 7 is configured to be able to change the display mode by inverting the front surface or the back surface of the disk. The display unit 7 displays, for example, the surface of the disc when the power is off, and displays the back of the disc when the power is on.

  The alarm device 1 drives the battery 10 (secondary battery) as a power supply. The battery 10 has a capacity of, for example, 3V. The alarm device 1 is driven at a predetermined operating voltage. The alarm device 1 does not operate when the battery voltage is lower than a predetermined operating voltage value (hereinafter referred to as “stop voltage value a1”). The alarm 1 ceases to operate, for example, when the battery voltage drops to approximately 2 V or less.

The alarm device 1 automatically measures the battery voltage every predetermined time set in advance. The alarm device 1 stores information related to the measured value of the battery voltage in the storage device 8 of the control unit 2 together with information related to the measured time. The notification unit 4 gives notification in different modes, for example, when the battery voltage decreases or when the battery voltage decreases abnormally early. The lamp unit 5 lights in different modes when the battery voltage decreases or when the battery voltage decreases abnormally early.
The alarm device 1 is configured to be able to change the operation mode according to the measured value of the battery voltage. The alarm device 1 has a normal mode, a low voltage mode, and an abnormal mode as operation modes.

  The alarm device 1 starts an operation of detecting a change in the external environment after the power is turned on and initialization and the like are performed. The alarm device 1 first operates in the normal mode when the operation of detecting a change in the external environment is started. The alarm device 1 performs an operation of detecting the presence or absence of an abnormality of the battery voltage in the normal mode. The normal mode is a normal operation mode of the alarm 1, and the battery voltage is sufficient for the alarm 1 to be driven.

  When the value of the battery voltage drops below a predetermined voltage value (hereinafter referred to as “low voltage value a2”) immediately before the alarm 1 becomes unoperable (stops operation), the alarm 1 Operate in low voltage mode. In the alarm device 1, the low voltage value a2 is set to a value (for example, 2.4 V) higher than the stop voltage value a1.

  The alarm device 1 operates in the abnormal mode when the measured battery voltage drops abnormally early.

  Next, a series of operations for measuring the battery voltage in the alarm device 1 and changing the operation mode will be described with reference to FIG. 2 or 3.

As shown in FIG. 2 or 3, the alarm device 1 first operates in the normal mode (step S101).
In the normal mode, the alarm device 1 measures the battery voltage every predetermined time (for example, every 28 hours). In the normal mode, the notification unit 4 does not notify that the battery voltage has dropped or that the normal mode is in effect. In the normal mode, the lamp unit 5 is off. The display unit 7 displays the back of the disc.
After starting the operation in the normal mode, the process proceeds to step S102.

Next, in the alarm device 1, the control unit 2 determines whether the measured battery voltage value is less than a predetermined voltage value (hereinafter referred to as "appropriate voltage value a3") that is appropriate for the operation of the alarm device 1. Is determined (step S102).
In the alarm device 1, the appropriate voltage value a3 is set to a value (for example, 2.7 V) higher than the low voltage value a2.
The control unit 2 determines whether the measured value of the battery voltage is less than the appropriate voltage value a3 continuously (for example, twice continuously) a predetermined number of times. When the measured battery voltage value is not continuously less than the appropriate voltage value a3 for a predetermined number of times, the control unit 2 determines that the measured battery voltage value is not less than the appropriate voltage value a3.
When the control unit 2 determines that the measured battery voltage value is less than the appropriate voltage value a3, the process proceeds to step S103.
When the control unit 2 determines that the measured battery voltage value is not less than the appropriate voltage value a3, the control unit 2 determines whether the measured battery voltage value is less than the appropriate voltage value a3 (step S102) Repeat).
The control unit 2 may be configured to determine whether the measured battery voltage value is less than the appropriate voltage value a3 at one time. At this time, when the measured battery voltage value is not less than the appropriate voltage value a3 at one time, the control unit 2 determines that the measured battery voltage value is not less than the appropriate voltage value a3.

Next, in the alarm device 1, the control unit 2 determines whether or not the measured battery voltage value is equal to or lower than the low voltage value a2 (step S103).
At this time, the control unit 2 determines whether the measured value of the battery voltage is equal to or less than the low voltage value a2 continuously (for example, five times continuously) a predetermined number of times. When the measured battery voltage value is not continuously lower than the low voltage value a2 for a predetermined number of times, the control unit 2 determines that the measured battery voltage value is not lower than the low voltage value a2.
If the control unit 2 determines that the measured battery voltage value is equal to or lower than the low voltage value a2, the process proceeds to step S104.
If the control unit 2 determines that the value of the measured battery voltage is not the low voltage value a2 or less, the process proceeds to step S110.

Next, the alarm device 1 starts operation in the low voltage mode (step S104).
In the low voltage mode, the alarm device 1 measures the battery voltage every predetermined time (for example, every 14 hours). In the low voltage mode, the alarm 1 measures the battery voltage at intervals shorter than the normal mode.
In the low voltage mode, the notification unit 4 notifies in a mode different from the mode in which a change in the external environment is detected and reported or the mode in the abnormal mode. In the voltage mode, the notification unit 4 emits a sound, for example, every 30 seconds.
In the low voltage mode, the lamp unit 5 lights in a mode different from the mode in which a change in the external environment is detected and reported, the mode in the normal mode, or the mode in the abnormal mode. In the low voltage mode, the lamp unit 5 blinks at intervals of, for example, 30 seconds, or lights up with a color changed from the normal mode. In the low voltage mode, the display unit 7 displays the back of the disc.
After the operation in the low voltage mode is started, the process proceeds to step S105.

Next, in the alarm device 1, in the low voltage mode, a predetermined voltage amount (hereinafter referred to as “abnormal voltage amount”) in which the amount of decrease of the value of the battery voltage measured most recently from the value of the battery voltage measured last time The control unit 2 determines whether or not it is less than “)” (step S105).
In the alarm device 1, the abnormal voltage amount is set to 10 mV, for example. In the alarm device 1, the value is set to 1/500 or more of the battery capacity.
When the decrease amount of the battery voltage value measured most recently from the value of the battery voltage measured last time is not less than the abnormal voltage amount even once, the decrease amount of the battery voltage value measured most recently from the value of the battery voltage measured last time Is not less than the abnormal voltage amount, the control unit 2 determines.
When the control unit 2 determines that the decrease amount of the value of the battery voltage measured most recently from the value of the battery voltage measured last time is less than the abnormal voltage amount, the process proceeds to step S106.
When the control unit 2 determines that the decrease amount of the value of the battery voltage measured most recently from the value of the battery voltage measured previously is not smaller than the abnormal voltage amount, the process proceeds to step S115.

Next, in the alarm device 1, the control unit 2 determines whether or not the measured battery voltage value is an abnormal voltage in the low voltage mode (step S106).
At this time, in the alarm device 1, a predetermined voltage amount (hereinafter referred to as "abnormal detection voltage amount") in which the decrease amount of the battery voltage value measured most recently from the value of the battery voltage measured last time is abnormally reduced. The control unit 2 determines whether or not it is the above, and when it is determined that the abnormality detection voltage amount or more, the control unit 2 determines that the voltage is an abnormal voltage.
In the alarm device 1, the abnormality detection voltage amount is set to a value (for example, 5 mV) lower than the abnormality voltage amount. In the alarm device 1, the abnormality detection voltage amount is set to a value of 1/500 to 1/1000 of the capacity of the battery 10.
When the amount of decrease of the value of the battery voltage measured most recently from the value of the battery voltage measured last time is equal to or more than the abnormality detection voltage amount continuously for a predetermined number of times (for example 5 consecutive times), the value of battery voltage measured last time The controller 2 determines that the amount of decrease of the battery voltage value measured in the above is equal to or greater than the abnormality detection voltage amount, and the controller 2 determines that the voltage is an abnormal voltage.
When the control unit 2 determines that the measured battery voltage value is an abnormal voltage, the process proceeds to step S115.
If the control unit 2 determines that the measured battery voltage value is not an abnormal voltage, the process proceeds to step S105.

Next, in the alarm device 1, in the normal mode, the control unit 2 determines whether or not the decrease amount of the value of the battery voltage measured most recently from the value of the battery voltage measured last time is less than the abnormal voltage amount (step S110).
If the control unit 2 determines that the decrease amount of the value of the battery voltage measured most recently from the value of the battery voltage measured last time is less than the abnormal voltage amount, the process proceeds to step S111.
When the control unit 2 determines that the decrease amount of the value of the battery voltage measured most recently from the value of the battery voltage measured previously is not smaller than the abnormal voltage amount, the process proceeds to step S115.

Next, in the alarm device 1, the control unit 2 determines whether or not the measured battery voltage value is an abnormal voltage in the normal mode (step S111).
At this time, in the alarm device 1, the control unit 2 determines whether the decrease amount of the battery voltage value measured most recently from the value of the battery voltage measured last time is equal to or more than the abnormality detection voltage amount. When it is determined that the voltage is above, the control unit 2 determines that the voltage is an abnormal voltage. At this time, in the alarm device 1, the control unit 2 determines whether the measured battery voltage value is less than a predetermined voltage value (hereinafter referred to as "abnormal detection voltage value a4") which is considered to be abnormally low. When it is determined that the voltage is less than the abnormality detection voltage value a4, the control unit 2 determines that the voltage is an abnormal voltage.
In the alarm device 1, the abnormality detection voltage value a4 is set to a value (for example, 2.6 V) lower than the appropriate voltage value a3 and higher than the low voltage value a2. In the alarm device 1, the abnormality detection voltage value a4 is set to a value of 80% to 90% of the capacity of the battery 10. In the alarm device 1, the abnormality detection voltage value a4 is set to 120% to 135% of the stop voltage value a1.
When the amount of decrease of the value of the battery voltage measured most recently from the value of the battery voltage measured last time is equal to or more than the abnormality detection voltage amount continuously for a predetermined number of times (for example 5 consecutive times), the value of battery voltage measured last time The controller 2 determines that the amount of decrease of the battery voltage value measured in the above is equal to or greater than the abnormality detection voltage amount, and the controller 2 determines that the voltage is an abnormal voltage. In addition, when the measured battery voltage value is less than the abnormality detection voltage value a4 continuously for a predetermined number of times (for example, five consecutive times), the control unit determines that the value of the measured battery voltage is less than the abnormality detection voltage value a4. 2 is judged, and the controller 2 judges that the voltage is an abnormal voltage.
When the control unit 2 determines that the measured battery voltage value is an abnormal voltage, the process proceeds to step S115.
If the control unit 2 determines that the measured battery voltage value is not an abnormal voltage, the process proceeds to step S102.

Next, in the alarm device 1, the operation in the abnormal mode is started on the assumption that the battery voltage is abnormally rapidly decreased (step S115).
In the abnormal mode, the alarm device 1 stops the operation of measuring the battery voltage.
In the abnormal mode, the notification unit 4 notifies in a mode different from the mode in which a change in the external environment is detected and reported or the mode in the low voltage mode. In the voltage mode, the notification unit 4 emits a sound, for example, every 5 seconds.
In the abnormal mode, the lamp unit 5 lights in a mode different from the mode in which the change of the external environment is detected and notified, the mode in the normal mode, or the mode in the low voltage mode. In the abnormal mode, the lamp unit 5 blinks, for example, at intervals of 50 seconds. In the abnormal mode, the display unit 7 displays the back of the disc.
As described above, the alarm device 1 performs a series of operations for measuring the battery voltage and changing the operation mode.

As described above, in the normal mode, when the measured battery voltage value is not less than the appropriate voltage value a3 (is more than the appropriate voltage value a3), transition to another operation mode (low voltage mode and abnormal mode) The alarm device 1 does not shift to another operation mode when the battery voltage is appropriate when the alarm device 1 operates, and does not perform an operation to determine whether the measured battery voltage value is an abnormal voltage.
Therefore, according to the alarm 1, it is possible to suppress the power consumption of the alarm 1 when the voltage is equal to or more than the appropriate voltage value a3.

As described above, in the low voltage mode, the battery voltage is measured at intervals shorter than the normal mode. In the alarm device 1, when the measured battery voltage value falls below the low voltage value a2, it is shorter than the normal mode Measure the battery voltage at intervals.
Therefore, according to the alarm device 1, the presence or absence of abnormality of the battery voltage is detected more quickly in the low voltage mode (when the measured battery voltage value falls to the low voltage value a2 or less) than in the normal mode. can do.
The alarm device 1 can also measure the battery voltage at intervals longer than the normal mode in the low voltage mode. With such a configuration, it is possible to suppress the power consumption of the alarm device 1 when the value of the battery voltage falls to the low voltage value a2 or less.

As described above, in the low-voltage mode, the alarm unit 4 reports in a mode different from the mode in which a change in the external environment is detected and reported or the mode in the abnormal mode. When the value of the battery voltage decreases to the low voltage value a2 or less, the notification unit 4 notifies in a mode different from the mode or the like in the abnormal mode.
Therefore, according to the alarm device 1, it is prevented that the notification by the notification unit 4 is erroneously recognized as the one in the abnormal mode or the like, and it is surely notified that the battery voltage is the low voltage value a2 or less. Can.

As described above, in the low voltage mode, the lamp unit 5 lights up in a mode different from the mode in which a change in the external environment is detected and reported or the mode in the abnormal mode. When the value of the battery voltage drops to the low voltage value a2 or less, the lamp unit 5 lights up in a mode different from the mode etc. in the abnormal mode.
Therefore, according to the alarm device 1, it is prevented that the lighting by the lamp unit 5 is erroneously recognized as the one in the abnormal mode or the like, and it is surely notified that the battery voltage is the low voltage value a2 or less. Can.

As described above, in the alarm device 1, which operates in the abnormal mode when the battery voltage falls abnormally early, in the alarm device 1, when the battery voltage falls abnormally, the notification unit 4 notifies in a mode different from the normal mode etc. Alternatively, the lamp unit 5 is turned on, and the operation of measuring the battery voltage is stopped.
Therefore, according to the alarm device 1, it is prevented that the notification by the notification unit 4 when the battery voltage falls abnormally or the lighting by the lamp unit 5 is erroneously recognized as the one in the normal mode etc. It can indicate that the voltage has dropped abnormally early. Moreover, according to the alarm device 1, it is possible to suppress the power consumption of the alarm device 1 when the battery voltage drops abnormally early.

As described above, in the normal mode or the low voltage mode, when the measured battery voltage value is an abnormal voltage continuously for a predetermined number of times, the transition to the abnormal mode is made. In the alarm device 1, the measured battery voltage value is predetermined The operation in the abnormal mode is started when the abnormal voltage is generated continuously for a number of times.
Therefore, according to the alarm device 1, it is possible to reliably detect that the battery voltage has dropped abnormally early and to start the operation in the abnormal mode.

As described above, in the normal mode or the low voltage mode, when the amount of decrease of the value of the battery voltage measured most recently from the value of the battery voltage measured previously is equal to or more than the abnormality detection voltage continuously for a predetermined number of times In the alarm device 1 to shift, the operation in the abnormal mode is started when the amount of decrease of the value of the battery voltage measured most recently from the value of the battery voltage measured last time is equal to or more than the abnormality detection voltage continuously for a predetermined number of times. Do.
Therefore, according to the alarm device 1, it is possible to reliably detect that the battery voltage has dropped abnormally early and to start the operation in the abnormal mode.

As described above, in the normal mode or the low voltage mode, when the amount of decrease of the value of the battery voltage measured most recently from the value of the battery voltage measured previously is not less than the amount of abnormal voltage (more than the amount of abnormal voltage) In the alarm device 1, when the reduction amount of the value of the battery voltage measured most recently from the value of the battery voltage measured last time is abnormally high, the alarm device 1 does not continue the operation of measuring the battery voltage in the abnormal mode. Start operation.
Therefore, according to the alarm 1, it is possible to suppress the power consumption of the alarm 1 when the amount of decrease of the value of the battery voltage measured most recently from the value of the battery voltage measured last time is abnormally high.

As described above, in the abnormal mode, the alarm unit 4 reports in a mode different from the mode in which a change in the external environment is detected and reported or the mode in the low voltage mode, and the alarm unit 4 measures When the battery voltage drops abnormally early (in the abnormal mode), the notification unit 4 notifies in a mode different from the mode or the like in the low voltage mode.
Therefore, according to the alarm device 1, it is prevented that the notification by the notification unit 4 is erroneously recognized as the one in the low voltage mode or the like, and the battery voltage is surely abnormally rapidly reduced. I can tell.

As described above, in the abnormal mode, the lamp unit 5 lights up in a mode different from the mode in which the change in the external environment is detected and reported or the mode in the low voltage mode. When the battery voltage is abnormally reduced (in the abnormal mode), the lamp unit 5 is lit in a mode different from the mode or the like in the low voltage mode.
Therefore, according to the alarm device 1, it is prevented that the lighting by the lamp unit 5 is erroneously recognized as the one in the low voltage mode or the like, and the battery voltage is surely abnormally rapidly reduced. I can tell.

The alarm device 1 can also be configured such that the operation mode of measuring the battery voltage in the normal mode or the low voltage mode is different depending on the value of the measured battery voltage. In the normal mode or the low voltage mode, when the control unit 2 determines whether or not the value of the measured battery voltage is an abnormal voltage (step S106 or step S111), the alarm device 1 measures an interval at which the battery voltage is measured, or The number of times (continuous number of times) of measuring the battery voltage when it is determined to be an abnormal voltage may be configured to be different depending on the value of the measured battery voltage.
For example, in step S111, when the measured battery voltage value is relatively high, the battery voltage measurement interval is made relatively long, and the number of times the battery voltage is measured when it is determined to be abnormal voltage is compared. Make many At this time, when the measured battery voltage value is, for example, 2.6 V or more and less than 2.7 V, the battery voltage measurement interval is, for example, every three hours, or the measured battery voltage value is abnormal for seven consecutive times. The control unit 2 determines that the voltage is an abnormal voltage when
Further, for example, in step S111, when the measured battery voltage value is relatively low, the interval for measuring the battery voltage is relatively shortened, and the number of times the battery voltage is measured when it is determined that the voltage is abnormal. Relatively less. At this time, when the measured battery voltage value is, for example, 2.4 V or more and less than 2.6 V, the battery voltage measurement interval is, for example, every 30 minutes, or the measured battery voltage value is abnormal three consecutive times. The control unit 2 determines that the voltage is an abnormal voltage when
By configuring in this way, in the normal mode or the low voltage mode, transition to the abnormal mode is promptly made by the value of the measured battery voltage, or it is reliably detected that the battery voltage has dropped abnormally early, or Power consumption when measuring the battery voltage can be suppressed.

In the alarm device 1, when the notification unit 4 detects a change in the external environment, in the low voltage mode or in the abnormal mode, instead of emitting a sound or in combination with the sound, the external environment It is also possible to notify by communicating to the outside information on detection of change in information, information on start of operation in the low voltage mode, or information on start of operation in the abnormal mode.
By this configuration, it is possible to notify the outside (a place other than the place where the alarm 1 is installed) that the operation in the low voltage mode has been started.

The alarm device 1 operates the operation unit 6 to detect whether or not the notification unit 4 notifies when the change in the external environment is detected, in the low voltage mode, or in the abnormal mode. The notification mode of the unit 4 (for example, the communication destination when the notification unit 4 communicates to the outside) or the like may be settable.
By configuring in this manner, it is possible to make a state where notification by the notification unit 4 is not performed by a simple operation of the operation unit 6, or make it possible to set a notification mode by the notification unit 4 as desired.

The alarm device 1 operates the operation unit 6 to detect whether the lamp unit 5 is lit or not in the low voltage mode or the abnormal mode when detecting a change in the external environment, or a lamp The lighting mode and the like of the unit 5 can also be configured to be settable. Further, the alarm device 1 can set the display mode of the display unit 7 or the like in the low voltage mode or the abnormal mode when detecting a change in the external environment by operating the operation unit 6 It can also be configured.
With this configuration, the lamp unit 5 can be turned off by a simple operation of the operation unit 6, or the display mode by the lamp unit 5 or the display mode by the display unit 7 can be desired. It can be

The alarm device 1 can also be configured to shift from the low voltage mode or the like to the normal mode by operating the operation unit 6 in the low voltage mode or in the abnormal mode.
By configuring in this manner, a person who notices a state other than the normal mode (a state such as a low voltage mode) operates the operation unit 6 to perform battery replacement, maintenance work, etc. in the normal mode state. it can.

In the alarm device 1, the notification unit 4 continues the notification operation in the notified mode until the operation mode is changed after the notification operation is started in each operation mode. The alarm device 1 can also be configured to stop the operation notified by the notification unit 4 by operating the operation unit 6.
By configuring in this manner, an operation in which the notification unit 4 notifies battery replacement, maintenance work, and the like when a person who notices a state other than the normal mode (a state such as a low voltage mode) operates the operation unit 6 It can be done in the stopped state.

The alarm device 1 can be configured to set the value of the appropriate voltage value a3, the low voltage value a2, the abnormal voltage amount, the abnormal detection voltage amount, or the abnormal detection voltage value a4 by operating the operation unit 6. You can also.
By configuring in this way, the desired voltage value a3, low voltage value a2, abnormal voltage amount, abnormal detection voltage amount, or abnormal detection voltage value a4 can be made as desired by simple operation of the operation unit 6. can do.

The alarm device 1 operates the operation unit 6 to measure the battery voltage (a mode of transition to the low voltage mode, or a value of the battery voltage when the control unit 2 determines that the voltage is an abnormal voltage). It is also possible to change the number of times of counting, the interval of measuring the battery voltage, and the like.
By configuring in this manner, it is possible to make the operation mode of measuring the battery voltage by a simple operation of the operation unit 6 desired.

The alarm device 1 is configured to measure the battery voltage by operating the operation unit 6 (for example, the operator operates the operation unit 6 at the time of periodic inspection) instead of automatically measuring the battery voltage. Alternatively, the battery voltage may be measured by operating the operation unit 6 together with automatically measuring the battery voltage.
For example, the alarm device 1 measures the battery voltage by operating the operation unit 6, and when there is a possibility of an abnormal voltage in the measured battery voltage, a sound indicating that the battery voltage is automatically detected ( For example, the notification unit 4 emits "confirm because there is a possibility of abnormal voltage." And automatically starts measurement of the battery voltage.
Further, for example, the alarm device 1 measures the battery voltage by operating the operation unit 6, and if there is a possibility of an abnormal voltage in the measured battery voltage, the battery voltage can be continuously measured by operating the operation unit 6. A voice (eg, "Please check for possible abnormal voltage," for example) to cause detection is issued and the operator continues to measure the battery voltage.
Further, the notification unit 4 can be configured to emit the measurement result of the battery voltage by voice immediately after the measurement of the battery voltage (immediately after the operation unit is operated) or immediately after the measurement of the battery voltage next time.

  As shown in FIG. 4, the alarm device 1 may be configured not to include the operation (step S102) of determining whether the measured battery voltage value is less than the appropriate voltage value a3. In such a configuration, after the operation is started in the normal mode in step S101, the process proceeds to step S103. With such a configuration, it is possible to perform an operation of changing the operation mode with simpler control.

  As shown in FIG. 5, in the alarm device 1, in the normal mode or the low voltage mode, control is performed as to whether or not the reduction amount of the battery voltage value measured most recently from the battery voltage value measured previously is less than the abnormal voltage amount. The configuration may be such that the operation (steps S105 and S110) determined by the unit 2 is not included. In such a configuration, after the operation in the low voltage mode is started in step S104, the process proceeds to step S106, and after the controller 2 determines that the voltage value measured in step S103 is not less than the low voltage value a2, the process proceeds to step S111.

By this configuration, the operation to change the operation mode can be performed with simpler control, or the power consumption of the alarm device 1 when the value of the battery voltage falls below the low voltage value a2 can be suppressed. can do.
Further, at this time, after the operation in the low voltage mode is started in step S104, the operation to measure the battery voltage may not be performed, and the notification operation by the notification unit 4 or the lighting operation by the lamp unit 5 may not be performed. . With such a configuration, it is possible to further suppress the power consumption of the alarm device 1 when the value of the battery voltage falls to the low voltage value a2 or less.
At this time, the alarm device 1 does not automatically measure the battery voltage in the low voltage mode, but may be configured to measure the battery voltage by operating the operation unit 6.

As shown in FIG. 2 or FIG. 7, the alarm device 1 operates when the value of the battery voltage falls below a predetermined voltage value (hereinafter referred to as the “end voltage value a5”) closest to the stop voltage a1. Can be configured to stop. In the alarm device 1, the end voltage value a5 is set to a value (for example, 2.1 V) lower than the low voltage value a2 and higher than the stop voltage value a1.
In the alarm device 1 configured as described above, when the control unit 2 determines that the value of the measured battery voltage is less than or equal to the low voltage value a2 in step S103, the process proceeds to step S116. Then, the control unit 2 determines whether the measured value of the battery voltage is equal to or less than the termination voltage value a5 (step S116). At this time, the control unit 2 determines whether the measured value of the battery voltage is less than or equal to the termination voltage value a5 continuously (for example, five times continuously) a predetermined number of times. When the measured battery voltage value is not continuously less than the termination voltage value a5 for a predetermined number of times, the control unit 2 determines that the measured battery voltage value is not less than the termination voltage value a5.
If the control unit 2 determines that the measured battery voltage value is equal to or less than the termination voltage value a5, the process proceeds to step S117.
If the control unit 2 determines that the value of the measured battery voltage is not less than or equal to the termination voltage value a5, the process proceeds to step S104.
Next, the alarm device 1 stops its operation (step S117). At this time, the display unit 7 displays the surface of the disc on the assumption that the power is turned off. The stop of the operation of the alarm device 1 includes, for example, the stop of the operation of measuring the battery voltage, the stop of the operation of detecting the change of the external environment of the sensor unit 3, the stop of the notification operation by the notification unit 4 and the lighting of the lamp unit 5. A state in which at least two operations of the display unit 7 (displaying the surface of the disk of the display unit 7) are stopped is shown. In the alarm device 1, the state in which the at least two operations are stopped may be set in advance, or may be set by operating the operation unit 6.

  The alarm device 1 does not perform an operation (step S102) in which the control unit 2 determines whether the value of the measured battery voltage is less than the appropriate voltage value a3 by operating the operation unit 6, in the normal mode etc. Do not perform the operation (step S105, step S110) in which the control unit 2 determines whether or not the decrease amount of the battery voltage value measured most recently from the measured battery voltage value is less than the abnormal voltage amount or low voltage mode Do not perform the operation (Step S116) in which the control unit 2 determines whether the operation of measuring the battery voltage (Step S105, Step S106) is not performed or the measured value of the battery voltage is less than the termination voltage value a5. , Etc. can also be configured. With such a configuration, it is possible to make the operation mode for measuring the battery voltage of the alarm device 1 and the like desired by the simple operation of the operation unit 6.

The alarm device 1 can also be configured to display the surface of the disk of the display unit 7 on the assumption that the power is turned off in the low voltage mode or the abnormal mode.
The display unit 7 may be configured by a lamp member, and may be configured to light in different modes, for example, when the power is off and when the power is on.
The alarm device 1 can be configured not to include the display unit 7. At this time, the lamp unit 5 may be configured to be lit (for example, continuously lit) when the power is turned on, in a mode different from the lighting mode in the low voltage mode or the abnormal mode.

In the normal mode, the notification unit 4 does not notify that the battery voltage has dropped or that the normal mode is in effect. In the normal mode, the lamp unit 5 is off. The display unit 7 displays the back of the disc.
After starting the operation in the normal mode, the process proceeds to step S202.

Next, in the alarm device 1, the control unit 2 determines whether or not the measured battery voltage value is less than the appropriate voltage value a3 (step S202).
The control unit 2 determines whether the measured value of the battery voltage is less than the appropriate voltage value a3 continuously (for example, twice continuously) a predetermined number of times. When the measured battery voltage value is not continuously less than the appropriate voltage value a3 for a predetermined number of times, the control unit 2 determines that the measured battery voltage value is not less than the appropriate voltage value a3.
If the control unit 2 determines that the measured battery voltage value is less than the appropriate voltage value a3, the process proceeds to step S203.

When the amount of decrease of the battery voltage value measured most recently from the value of the battery voltage measured last time is equal to or greater than the abnormality detection voltage even once, the value of the battery voltage measured most recently from the value of the battery voltage measured last time The control unit 2 determines that the reduction amount is equal to or more than the abnormality detection voltage amount, and the control unit 2 determines that the voltage is an abnormality.
If the control unit 2 determines that the measured battery voltage value is an abnormal voltage, the process proceeds to step S207.
If the control unit 2 determines that the measured battery voltage value is not an abnormal voltage, the process proceeds to step S205.
The control unit 2 determines whether the amount of decrease of the battery voltage value measured most recently from the previously measured battery voltage value is equal to or more than the abnormality detection voltage amount continuously for a predetermined number of times (for example, twice continuously). It can also be done. At this time, when the decrease amount of the battery voltage value measured most recently from the value of the battery voltage measured last time is equal to or more than the abnormality detection voltage amount continuously for a predetermined number of times, the battery voltage value measured last time was measured most recently.

In the abnormal mode, the alarm device 1 stops the operation of measuring the battery voltage.
In the abnormal mode, the notification unit 4 notifies in a mode different from the mode in which a change in the external environment is detected and reported, the mode in the low voltage mode, or the mode in the abnormal detection mode. In the voltage mode, the notification unit 4 emits a sound, for example, every 5 seconds.

In the alarm device 1, when the value of the measured battery voltage decreases to the low voltage value a2 or less, the notification unit 4 notifies in a mode different from the mode or the like in the abnormal mode.

Therefore, according to the alarm device 1, the presence or absence of the battery voltage abnormality can be detected more quickly than in the normal mode or the low voltage mode.

As described above, in the normal mode or the low voltage mode, when the measured battery voltage value is an abnormal voltage, transition to the abnormality detection mode is made. In the alarm device 1, the measured battery voltage value is, for example, even once When the voltage is an abnormal voltage, the battery voltage is measured at intervals shorter than the normal mode or the low voltage mode to start an operation of detecting the presence or absence of the battery voltage abnormality.

It can be reliably notified that it is in a state of detecting the presence or absence of (a state in which there is a possibility that there is an abnormality in the battery voltage).

As described above, in the abnormality detection mode, when the measured battery voltage value is continuously abnormal for a predetermined number of times, transition to the abnormal mode is made. In the alarm device 1, the value of the measured battery voltage is continuously for a predetermined number of times When the voltage is abnormal, operation in the abnormal mode is started.
Therefore, according to the alarm device 1, it is possible to reliably detect that the battery voltage has dropped abnormally early and to start the operation in the abnormal mode.

As described above, in the normal mode, the low voltage mode, or the abnormality detection mode, the amount of decrease in the value of the battery voltage measured most recently from the value of the battery voltage measured last time is not less than the amount of abnormal voltage In the alarm unit 1, the battery voltage continues to be measured when the amount of decrease in the battery voltage value measured most recently from the previously measured battery voltage value is abnormally high. Start operation in abnormal mode.
Therefore, according to the alarm 1, it is possible to suppress the power consumption of the alarm 1 when the amount of decrease of the value of the battery voltage measured most recently from the value of the battery voltage measured last time is abnormally high.

As described above, in the abnormal mode, the notification unit 4 notifies in a mode different from the mode in which the change of the external environment is detected and reported, the mode in the low voltage mode, or the mode in the abnormal detection mode. In the alarm device 1, when the measured battery voltage is abnormally rapidly decreased (in the abnormal mode), the notification unit 4 notifies in a mode different from the mode or the like in the abnormal detection mode.
Therefore, according to the alarm device 1, it is prevented that the notification by the notification unit 4 is erroneously recognized as the one in the abnormality detection mode or the like, and the battery voltage is surely abnormally rapidly reduced. I can tell.

As described above, in the abnormal mode, the lamp unit 5 lights in a mode different from the mode in which the change in the external environment is detected and notified, the mode in the low voltage mode, or the mode in the abnormality detection mode. In the alarm device 1, when the measured battery voltage drops abnormally early (in the abnormal mode), the lamp unit 5 is lit in a mode different from the mode or the like in the abnormal detection mode.
Therefore, according to the alarm device 1, it is prevented that the lighting by the lamp unit 5 is erroneously recognized as the one in the abnormality detection mode or the like, and the battery voltage is surely abnormally rapidly reduced. I can tell.

The alarm device 1 can also be configured to change the operation mode of measuring the battery voltage in the abnormality detection mode depending on the value of the measured battery voltage. When the control unit 2 determines whether the measured battery voltage value is an abnormal voltage or not in the abnormality detection mode (step S209 or step S214), the alarm device 1 measures an interval at which the battery voltage is measured or at an abnormal voltage. The number of times (continuous number of times) of measuring the battery voltage when it is determined to be present may be configured to be different depending on the value of the measured battery voltage.
For example, in step S214, when the measured battery voltage value is relatively high, the battery voltage measurement interval is made relatively long, and the number of times the battery voltage is measured when it is determined to be abnormal voltage is compared. Make many At this time, when the measured battery voltage value is, for example, 2.6 V or more and less than 2.7 V, the battery voltage measurement interval is, for example, every three hours, or the measured battery voltage value is abnormal for seven consecutive times. The control unit 2 determines that the voltage is an abnormal voltage when
Further, for example, in step S214, when the measured battery voltage value is relatively low, the interval for measuring the battery voltage is made relatively short, and the number of times for measuring the battery voltage when it is determined to be abnormal voltage is Relatively less. At this time, when the measured battery voltage value is, for example, 2.4 V or more and less than 2.6 V, the battery voltage measurement interval is, for example, every 30 minutes, or the measured battery voltage value is abnormal three consecutive times. The control unit 2 determines that the voltage is an abnormal voltage when
By configuring in this manner, in the abnormality detection mode, transition to the abnormal mode is promptly made according to the measured value of the battery voltage, or it is reliably detected that the battery voltage has dropped abnormally early, or the battery voltage It is possible to reduce power consumption when measuring

In the alarm device 1, when the notification unit 4 detects a change in the external environment, instead of emitting a sound in the low voltage mode, in the abnormality detection mode, or in the abnormality mode, in the low voltage mode, or At the same time, information on detecting changes in the external environment, information on starting operation in the low voltage mode, information on starting operation in the abnormality detection mode, or information on starting operation in the abnormality mode Information may be communicated to the outside.
By this configuration, it is possible to notify the outside (a place other than the place where the alarm 1 is installed) that the operation in the low voltage mode has been started.

When the alarm device 1 detects a change in the external environment by operating the operation unit 6, does the notification unit 4 notify when the low voltage mode, the abnormality detection mode, or the abnormal mode is detected? Alternatively, the notification mode of the notification unit 4 (for example, the communication destination when the notification unit 4 communicates to the outside) or the like may be settable.
By configuring in this manner, it is possible to make a state where notification by the notification unit 4 is not performed by a simple operation of the operation unit 6, or make it possible to set a notification mode by the notification unit 4 as desired.

Whether the lamp unit 5 lights up in the low voltage mode, in the abnormality detection mode, or in the abnormality mode when the alarm device 1 detects a change in the external environment by operating the operation unit 6 Alternatively, the lighting mode of the lamp unit 5 can be set. Further, when the alarm device 1 detects a change in the external environment by operating the operation unit 6, the display of the display unit 7 is performed in the low voltage mode, in the abnormality detection mode, or in the abnormality mode. It can also be configured to be settable for the aspect and the like.
With this configuration, the lamp unit 5 can be turned off by a simple operation of the operation unit 6, or the display mode by the lamp unit 5 or the display mode by the display unit 7 can be desired. It can be

The alarm device 1 can be configured to shift from the low voltage mode or the like to the normal mode by operating the operation unit 6 in the low voltage mode, the abnormality detection mode, or the abnormal mode. .
By configuring in this manner, a person who notices a state other than the normal mode (a state such as a low voltage mode) operates the operation unit 6 to perform battery replacement, maintenance work, etc. in the normal mode state. it can.

The alarm device 1 operates the operation unit 6 to measure the battery voltage (when transitioning to the low voltage mode, transitioning to the abnormality detection mode, or transitioning to the abnormality mode, the battery voltage) The number of times of measurement or the interval of measurement of the battery voltage may be changeable.
By configuring in this manner, it is possible to make the operation mode of measuring the battery voltage by a simple operation of the operation unit 6 desired.

The alarm device 1 is configured to measure the battery voltage by operating the operation unit 6 instead of automatically measuring the battery voltage, or is operated together with the automatic measurement of the battery voltage. The battery voltage can also be measured by operating the unit 6.
For example, the alarm device 1 is configured to measure the battery voltage by operating the operation unit 6 only in the normal mode. At this time, the notification unit 4 shifts to the abnormality detection mode, and issues a voice (for example, “Confirm because there is a possibility of an abnormal voltage.”) To automatically detect the battery voltage, and the abnormality detection mode. Migrate to
Further, for example, the alarm device 1 is configured to measure the battery voltage by operating the operation unit 6 in the normal mode and the abnormality detection mode. At this time, a voice to the effect that detection of the battery voltage is to be performed by operating the operation unit 6 by shifting to the abnormality detection mode (eg, "Please check because there is a possibility of an abnormal voltage.") The person measures the battery voltage in an operation mode (short measurement interval) different from the normal mode or the low voltage mode.
Further, the notification unit 4 can be configured to emit the measurement result of the battery voltage by voice immediately after the measurement of the battery voltage (immediately after the operation unit is operated) or immediately after the measurement of the battery voltage next time.

  As shown in FIG. 9, the alarm device 1 may be configured not to include the operation (step S202) of determining whether the measured battery voltage value is less than the appropriate voltage value a3. In such a configuration, after the operation is started in the normal mode in step S201, the process proceeds to step S203. With such a configuration, it is possible to perform an operation of changing the operation mode with simpler control.

  As shown in FIG. 10, in the alarm device 1, in the normal mode, the low voltage mode, or the abnormality detection mode, the decrease amount of the battery voltage value measured most recently from the value of the battery voltage measured previously is less than the abnormal voltage amount It may be configured not to include the operation (step S205, step S208, step S210, step S213) that the control unit 2 determines as to whether or not it is. In such a configuration, after the operation in the low voltage mode is started in step S204, the process proceeds to step S206, and after the operation in the abnormality detection mode is started in step S207, the process proceeds to step S209 and the voltage measured in step S203. After the controller 2 determines that the value is not the low voltage value a2 or less, the process proceeds to step S211, and after the operation in the abnormality detection mode is started in step S213, the process proceeds to step S214. With such a configuration, it is possible to perform an operation of changing the operation mode with simpler control.

As shown in FIG. 11, in the low voltage mode, the alarm device 1 can be configured not to include the operation of measuring the battery voltage (step S205, step S206, step S207, step S208, step S209). In such a configuration, after the operation in the low voltage mode is started in step S204, the notification operation by the notification unit 4 in the low voltage mode or the lighting operation by the lamp unit 5 is continued without performing the operation of measuring the battery voltage. Be done. By this configuration, the operation to change the operation mode can be performed with simpler control, or the power consumption of the alarm device 1 when the value of the battery voltage falls below the low voltage value a2 can be suppressed. can do.
At this time, after the operation in the low voltage mode is started in step S204, the operation of measuring the battery voltage may not be performed, and the notification unit 4 may not perform the notification operation or the lamp unit 5 may perform the lighting operation. . With such a configuration, it is possible to further suppress the power consumption of the alarm device 1 when the value of the battery voltage falls to the low voltage value a2 or less.
At this time, the alarm device 1 does not automatically measure the battery voltage in the low voltage mode, but may be configured to measure the battery voltage by operating the operation unit 6.

As shown in FIG. 2 or FIG. 12, the alarm device 1 can be configured to stop its operation when the value of the battery voltage falls below the termination voltage value a5.
In the alarm device 1 configured as described above, when the control unit 2 determines that the measured battery voltage value is the low voltage value a2 or less in step S203, the process proceeds to step S216. Then, the control unit 2 determines whether the measured value of the battery voltage is equal to or less than the termination voltage value a5 (step S216). At this time, the control unit 2 determines whether the measured value of the battery voltage is less than or equal to the termination voltage value a5 continuously (for example, five times continuously) a predetermined number of times. When the measured battery voltage value is not continuously less than the termination voltage value a5 for a predetermined number of times, the control unit 2 determines that the measured battery voltage value is not less than the termination voltage value a5.
If the control unit 2 determines that the measured battery voltage value is equal to or less than the termination voltage value a5, the process proceeds to step S217.
If the control unit 2 determines that the value of the measured battery voltage is not less than or equal to the termination voltage value a5, the process proceeds to step S204.
Next, the alarm device 1 stops its operation (step S217). At this time, the display unit 7 displays the surface of the disc on the assumption that the power is turned off. The stop of the operation of the alarm device 1 includes, for example, the stop of the operation of measuring the battery voltage, the stop of the operation of detecting the change of the external environment of the sensor unit 3, the stop of the notification operation by the notification unit 4 and the lighting of the lamp unit 5. This shows a state in which at least two operations of the operation stop, the display unit 7 display operation stop (display of the disk surface of the display unit 7), and the like are stopped. In the alarm device 1, the state in which the at least two operations are stopped may be set in advance, or may be set by operating the operation unit 6.

  The alarm device 1 does not perform an operation (step S202) in which the control unit 2 determines whether the measured battery voltage value is less than the appropriate voltage value a3 by operating the operation unit 6, in the normal mode etc. The operation (step S205, step S208, step S210, and step S213) is not performed in which the control unit 2 determines whether or not the decrease amount of the battery voltage value measured most recently from the measured battery voltage value is less than the abnormal voltage amount. , Do not perform the operation of measuring the battery voltage in the low voltage mode (step S205, step S206, step S207, step S208, step S209), or control whether the measured battery voltage value is the termination voltage value a5 or less It is also possible to set whether the operation (step S216) determined by the unit 2 is not performed.
