Embodiment 1
There are various alarm devices such as a fire alarm device and a gas leak alarm device. In addition, fire alarms include a fire alarm that detects smoke with a light emitting element and a light receiving element, a fire alarm that detects heat with a thermal element, and a fire alarm that detects flame with a pyroelectric element. An alarm is present. In the present embodiment, a case will be described in which the present invention is applied to a fire alarm that detects heat by a thermistor that is a thermal element.

  FIG. 1 is a circuit configuration diagram showing an internal circuit of a fire alarm. The fire alarm according to the present embodiment will be described with reference to FIG.

  The fire alarm includes a fire detection unit 5, a microcomputer 10 (hereinafter referred to as a microcomputer 10) that is a control unit, a voice recognition unit 17, a voice output unit 19, a power source 1, and the like.

(Microcomputer)
The microcomputer 10 includes a storage unit 11 that stores various flags, a timer unit 12, and a data unit 13 that stores various data, and the operation of the fire alarm is controlled by a CPU (not shown).

  The storage unit 11 is configured by a nonvolatile memory such as an EEPROM, for example. The storage unit 11 includes a Japanese flag 11a, an English flag 11b, a Chinese flag 11c, a Korean flag 11d set by a signal from a voice recognition unit (described later), a fire flag 11e that is set when a fire is detected, A test flag 11f for the test result and a fire sound stop flag 11g that is set while the fire sound is stopped are provided.

  The timer unit 12 is a timing device that measures 5 minutes, and measures 5 minutes after the voice is stopped as a time for performing the fire alarm again.

  The data unit 13 is composed of a nonvolatile memory such as an EEPROM, for example. The data unit 13 includes Japanese voice data 13a, English voice data 13b, Chinese voice data 13c, and Korean voice data 13d, which are language data used in each country to output a fire alarm, test results, and the like.

(Power supply)
For example, the power source 1, which is a lithium battery, constantly supplies power to the microcomputer 10 through the constant voltage circuit 4. Through the constant voltage circuit 4, stable power supply to the microcomputer 10 is possible. Note that the power source 1 is not necessarily a battery, and a power source that is smoothed by receiving a commercial power source from the outside may be used.

(Fire detection part)
The fire detection unit 5 includes a thermistor 6 and a resistor 7. The thermistor 6 and the resistor 7 are connected in series, and a constant voltage is applied to both ends of the fire detection unit 5 via the constant voltage circuit 4 from the power source 1. Yes. The microcomputer 10 receives a voltage divided by a resistance ratio by the thermistor 6 and the resistor 7. Since the resistance value of the thermistor 6 changes depending on the temperature, when the thermistor 6 is warmed during a fire, the voltage value between the thermistor 6 and the resistor 7 changes. The microcomputer 10 determines that a fire has occurred when the voltage value between the thermistor 6 and the resistor 7 becomes, for example, a fire level or higher. That is, the fire flag 11e of the storage unit 11 provided in the microcomputer 10 is set.

(Voice recognition unit)
The voice recognition unit 17 converts a voice signal emitted by a resident converted into an electric signal by the microphone 18 into voice data. The voice recognition unit 17 compares the converted voice data with reference voice data as in a technique such as a voice recognition method for selecting a destination used in a car navigation system by voice input. Then, the voice generated by the resident (user) is recognized, and a signal for setting the recognized language (use language) flags (Japanese flag, etc.) 11 a to 11 d is output to the microcomputer 10.

  As a speech recognition method, apart from the above, for example, a message such as “Please input your voice if you are Japanese” is output, and whether or not the resident has made a voice following that message. It is also possible to use a method of identifying the language used by the resident by outputting messages in each language and monitoring them. Also, a method combining these may be used.

(Audio output part)
The fire alarm device according to the first embodiment is provided with a sound output unit 19 that outputs sound. The audio output unit 19 includes an amplification unit 15, a speaker 16, a data unit 13 provided in the microcomputer 10, and a switch 14. The microcomputer 10 uses necessary data from the language voice data (Japanese voice data, etc.) 13a to 13d in the data section 13 according to the language flags 11a to 11d recognized by the storage section 11 via the voice output section 19. The voice is output to inform the resident about the fire alarm and test results.

  The switch 14 is normally open, and when the audio is output, the microcomputer 10 is switched and short-circuited to supply power to the amplifier 15 from the power source 1 via the constant voltage circuit 4. Excited. As a result, the power is not consumed in the sound output unit 19 except during sound output, so that power consumption is reduced.

(Audio stop switch)
The fire alarm is provided with a voice stop switch 8, and the voice stops when the voice stop switch 8 is operated while the fire alarm is sounding. During monitoring (other than during fire detection), the voice stop switch 8 also has a function as a test switch or a switch for recognizing a resident's language by a predetermined operation.

  The voice stop switch 8 is connected in series with the resistor 9, and a constant voltage is applied to both ends of the voice stop switch 8 from the power source 1 via the constant voltage circuit 4. The switch state is determined by the microcomputer 10 monitoring the voltage value between the voice stop switch 8 and the resistor 9. Here, when the voice stop switch 8 is not operated (open state), a constant voltage is input to the microcomputer 10 because a constant voltage is connected (pulled up) via the resistor 9. In this state, the microcomputer 10 recognizes that the voice stop switch 8 is not operated. In the state where the voice stop switch 8 is operated (short circuit state), the ground of the power source 1 is connected to the microcomputer 10 via the voice stop switch 8, and thus the ground potential is input. In this state, the microcomputer 10 determines that the voice stop switch 8 has been operated.

(Test Department)
The fire alarm has a test function. When the voice stop switch 8 is operated during monitoring, the fire alarm is set after setting the test flag 11f of the storage unit 11 provided in the microcomputer 10. Here, as the test of the first embodiment, a disconnection monitoring test and a power supply drop monitoring test are performed.

  The disconnection monitoring test is performed by the microcomputer 10 monitoring the voltage value between the thermistor 6 and the resistor 7. When the thermistor 6 is disconnected, the ground of the power source 1 is connected (pulled down) to the microcomputer 10 via the resistor 7, so that the ground potential is input. In this state, the microcomputer 10 determines that the thermistor 6 is disconnected, and clears the test flag 11 f of the storage unit 11 provided in the microcomputer 10.

  Although the disconnection of the thermistor 6 is detected in this embodiment, the deterioration of the thermistor 6 may be determined. For example, when the voltage value between the thermistor 6 and the resistor 7 falls within a predetermined range, it can be determined that the thermistor 6 has deteriorated.

  In the voltage drop monitoring test, the voltage monitoring circuit 2 tests whether the voltage value of the power source 1 is not more than a predetermined value via the switch 3. The voltage monitoring circuit 2 notifies the microcomputer 10 of a voltage drop of the power supply 1 when the voltage value of the power supply 1 becomes a predetermined value or less. Upon receiving the notification, the microcomputer 10 clears the test flag 11f of the storage unit 11 provided in the microcomputer 10.

  The switch 3 is normally open, and when the voltage drop monitoring test is performed, the microcomputer 10 is switched and short-circuited to connect the power source 1 to the voltage monitoring circuit 2 and perform the voltage drop monitoring test. Thus, power consumption is reduced because the voltage monitoring circuit 2 does not consume power except during the voltage drop monitoring test.

(Operation)
Next, the operation of the fire alarm will be described.
FIG. 2 is a flowchart showing the main operation of the fire alarm according to the first embodiment.
3 to 8 are flowcharts showing the operations shown in FIG.

  First, the main operation of the fire alarm will be described with reference to FIG. When power is supplied by connecting the power source 1 (step S1), the microcomputer 10 clears all the flags in the storage unit 11 and proceeds to step S3 (step S2). In step S3, the microcomputer 10 clears the 5-minute timer 12a of the timer unit 12. In step S4, the Japanese flag 11a of the storage unit 11 is set assuming that the default setting (initial setting) of audio output is Japanese. In step S5, the language used is recognized (details will be described later with reference to FIG. 3). In step S6, a fire is monitored (details will be described later with reference to FIG. 4). In step S7, input determination of the voice stop switch is performed (details will be described later with reference to FIG. 5). In step S8, a test is performed (details will be described later with reference to FIG. 6). In step S9, it is determined whether a test result (test normal) is output based on step S8. (Details will be described later with reference to FIG. 7). In step S10, it is determined whether to output a monitoring result (fire alarm) based on step S6 (details will be described later with reference to FIG. 8). After step S10 ends, the process returns to step S6, and fire monitoring and testing are performed again. In other words, the fire alarm monitors the fire every predetermined time.

  The details of the language recognition operation shown in step S5 in FIG. 2 will be described with reference to FIG. In order to inform the resident of the start of the use language setting, the microcomputer 10 sequentially outputs the start sound of the use language setting in Japanese, English, Chinese, and Korean through the sound output unit 19 (step S501). . Here, the start of the voice is, for example, "Please say hello if the Japanese.", "Please say hello if the Americans." Such as in the ..., the specific words of the (word) If the voice prompting pronunciation is output in order in each language, the reliability of voice recognition is improved.

  The microcomputer 10 determines whether or not the resident's voice is input via the voice recognition unit 17 (step S502). If it is determined that no voice is input, the process proceeds to the fire monitoring operation in step S6. If it is determined that speech is being input, one of the flags 11a to 11d of the recognized language in the storage unit 11 provided in the microcomputer 10 is set by a signal transmitted by the speech recognition unit 17 recognizing the language used. (Step S503), flags 11a to 11d other than the recognized language are cleared (step S504).

  After that, a confirmation voice for setting the language to be used based on the language voice data 13a to 13d of the recognized language flags 11a to 11d is outputted via the voice output unit 19 (step S505). For example, when the voice uttered by the recognized resident is in English, a voice output notifying the setting confirmation is performed in English to inform the resident that the alarm is set in English.

  Details of the fire monitoring operation shown in step S6 of FIG. 2 will be described with reference to FIG. The microcomputer 10 determines whether or not a fire has occurred based on the voltage value between the thermistor 6 and the resistor 7 (step S601). If it is determined that no fire has occurred, the fire flag 11e of the storage unit 11 provided in the microcomputer 10 is cleared (step S603), and the process proceeds to the 5-minute timer clear in step S608.

  If it is determined that a fire has occurred, the fire flag 11e of the storage unit 11 provided in the microcomputer 10 is set (step S602), and the fire voice stop flag 11g of the storage unit 11 provided in the microcomputer 10 is set. It is determined whether or not there is (step S604). If the fire sound stop flag 11g is not set, the process proceeds to 5 minutes timer clear in step S608.

  If the fire sound stop flag 11g is set, it is determined whether or not the 5-minute timer 12a of the timer unit 12 provided in the microcomputer 10 is counting (step S604). If the 5-minute timer 12a is not counting, the 5-minute timer 12a starts counting (step S606). If the 5-minute timer 12a is counting, it is determined whether or not the 5-minute timer has timed up (counting ended) (step S607).

  When the 5-minute timer 12a has timed up, 5 minutes have passed since the fire sound stop switch 8 was operated (fire sound stopped), so that the fire sound is sounded again for 5 minutes. The timer 12a is cleared (step S608), the fire sound stop flag 11g is cleared (step S609), and the process proceeds to the sound stop switch input determination in step S7.

  If the 5-minute timer 12a has not expired, since the fire sound stop switch 8 has been operated (fire sound is stopped), since five minutes have not elapsed, the process directly proceeds to the sound stop switch input determination in step S7. .

  The details of the voice stop switch input determination operation shown in step S7 of FIG. 2 will be described with reference to FIG. The microcomputer 10 determines whether or not the voice stop switch 8 is operated based on the voltage value between the voice stop switch 8 and the resistor 9 (step S701).

  If the voice stop switch 8 has not been operated, the process proceeds to a test operation in step S8. When the voice stop switch 8 is operated, it is determined whether the voice stop switch 8 has been operated for 3 seconds or longer (step S702), and the voice stop switch 8 has been operated for 3 seconds or longer. In such a case, it is determined that an operation for recognizing the language used has been performed, and the process proceeds to the language used recognition operation in step S5.

  If the operation of the voice stop switch 8 is less than 3 seconds, it is determined whether or not the fire flag 11e of the storage unit 11 provided in the microcomputer 10 is set (step S703). If the fire flag 11e is set, the fire sound stop flag 11g of the storage unit 11 included in the microcomputer 10 is set (step S704), and the process proceeds to step S8. If the fire flag 11e is not set, the test flag 11f is set (step S705), and the process proceeds to step S8.

Details of the test operation shown in step S8 of FIG. 2 will be described with reference to FIG.
The microcomputer 10 determines whether or not the fire flag 11e in the storage unit 11 is set (step S801). When the fire flag 11e is set, the test flag 11f of the storage unit 11 included in the microcomputer 10 is cleared (step S804), the test is terminated, and the process proceeds to the test result output operation of step S9. The test is terminated because it is necessary to output a fire alarm immediately when a fire has occurred.

  If the fire flag 11e is not set, the microcomputer 10 determines whether or not the thermistor 6 is disconnected based on the voltage value between the thermistor 6 and the resistor 7 as a disconnection monitoring test (step S803). If it is determined that the thermistor 6 is disconnected, the test flag 11f in the storage unit 11 is cleared (step S804), and the process proceeds to a test result output operation in step S9. If it is determined that the thermistor 6 is not disconnected, it is determined whether or not the voltage of the power source 1 is decreasing as a voltage drop monitoring test (step S805).

  Although not shown in the flowchart, the microcomputer 10 connects the voltage monitoring circuit 2 to the power supply 1 only during the voltage drop monitoring test by opening and closing the switch 3. If it is determined that the voltage of the power source 1 has decreased, the test flag 11f in the storage unit 11 is cleared (step S804), and the process proceeds to a test result output operation in step S9. If it is determined that the voltage of the power source 6 has not decreased, the test flag 11f in the storage unit 11 is not cleared, and the process proceeds to a test result output operation in step S9.

  Details of the test result output operation shown in step S9 of FIG. 2 will be described with reference to FIG. The microcomputer 10 determines whether or not the test flag 11f of the storage unit 11 is set (step S901). If the test flag 11f is not set, the process proceeds to the monitoring result output operation in step S10.

  Here, when the resident operates the voice stop switch during monitoring to perform the test (steps S701 to S704), the test result is not output (the test voice does not sound), so the fire alarm is abnormal. I know that there is.

  When the test flag 11f is set, it is determined whether or not the Japanese flag 11a of the storage unit 11 included in the microcomputer 10 is set (step S902), and the Japanese flag 11a is set. In this case, the test result is normal, and the Japanese voice data 13a of the data unit 13 is used to output a voice in Japanese test voice via the voice output unit 19 to notify the resident (step S903).

  If the Japanese flag 11a is not set, it is determined whether or not the English flag 11b is set (step S904). When the English flag 11b is set, the resident is informed that the test result is normal by using the English voice data 13b of the data part 13 and outputting the test voice in English via the voice output part 19. (Step S905).

  If the English flag 11b is not set, it is determined whether or not the Chinese flag 11c is set (step S906). If the Chinese flag 11c is set, the test result is normal. Is voice-output as Chinese test voice via the voice output unit 19 by the Chinese voice data 13c of the data unit 13 to notify the resident (step S907).

  If the Chinese flag 11c is not set, the test is normal and the resident voice is output by the Korean voice data 13d via the voice output unit 19 in the Korean test voice. (Step S908).

  Thus, after notifying that the test result is normal by the language used by the resident, the test flag 11f is cleared (step S909), and the process proceeds to the monitoring result output of step S10. Although not shown in the flowchart, the microcomputer 10 supplies power from the power source 1 to the amplifying unit 15 via the constant voltage circuit 4 only during voice output by opening and closing the switch 14.

  Details of the monitoring result output operation shown in step S10 of FIG. 2 will be described with reference to FIG. The microcomputer 10 determines whether or not the fire flag 11e in the storage unit 11 is set (step S1001). If the fire flag 11e is not set, the process returns to the fire monitoring operation in step S6.

  When the fire flag 11e is set, it is determined whether or not the fire sound stop flag 11g of the storage unit 11 is set (step S1002). When the fire sound stop flag 11g is set, The process returns to the fire monitoring operation in step S6. That is, since the fire sound stop switch 8 is operated and the fire sound is stopped (steps S701 to S704), the fire sound output is not performed.

  When the fire sound stop flag 11g is not set, it is determined whether or not the Japanese flag 11a of the storage unit 11 included in the microcomputer 10 is set (step S1003), and the Japanese flag 11a is set. If there is a fire, the Japanese voice data 13a of the data section 13 outputs a Japanese fire voice through the voice output section 19 and gives a fire alarm to inform the resident. (Step S1004).

  If the Japanese flag 11a is not set, it is determined whether or not the English flag 11b is set (step S1005). When the English flag 11b is set, a fire alarm is issued by outputting an English fire voice via the voice output section 19 by using the English voice data 13b of the data section 13 to indicate that a fire has occurred. The resident is notified (step S1006).

  If the English flag 11b is not set, it is determined whether or not the Chinese flag 11c is set (step S1007). If the Chinese flag 11c is set, a fire is output by voice output in Chinese fire voice via the voice output unit 19 using the Chinese voice data 13c of the data unit 13 to indicate that a fire has occurred. An alarm is given to inform the resident (step S1008).

  When the Chinese flag 11c is not set, the resident is informed that the fire has occurred by using the Korean voice data 13d via the voice output unit 19 in the Korean test voice. Step S1009).

  In this manner, the resident's language is used to notify that a fire has occurred, and the process returns to the fire monitoring operation in step S6. Although not shown in the flowchart, the microcomputer 10 supplies power from the power source 1 to the amplifying unit 15 via the constant voltage circuit 4 only during voice output by opening and closing the switch 14.

  In the present invention, the voice of the resident (user) is input to automatically recognize the language used by the resident. For this reason, the resident does not need to set a language to be used by a dip switch or the like. Therefore, it is possible to output a sound in the language used by the resident when detecting an abnormality in the monitoring area without causing the resident to take time.

  In addition, when the alarm is turned on, it recognizes the language used by the resident, so the language used can be set when installing the alarm in the residence, causing the resident to take time. This is convenient when the resident is installed in a fixed residence such as a house.

  In addition, when the voice stop switch is operated, the language used by the resident can be automatically recognized, which is convenient when installing in a residence where the resident changes frequently, such as a rental house. Good.

  In addition, since the voice prompting the resident to speak is output before performing the operation of automatically recognizing the language used by the resident, the resident will not forget to input the voice. In addition, since voice data in a plurality of languages is output as voice data that prompts the user to speak, foreigners who are not good at Japanese can easily forget to input voice.

  As described above, in the first embodiment, the disconnection monitoring test of the thermistor 6 and the voltage drop monitoring test of the power source 1 are performed as the internal circuit tests. However, these tests are only examples. For example, as an internal circuit test, it may be tested whether sound is output from the speaker 16.

  Moreover, although the fire alarm which detects heat was demonstrated in Embodiment 1, this is an example to the last. For example, you may implement this invention to the fire alarm which detects smoke with a light emitting element and a light receiving element. As a test, for example, the light receiving element output level is monitored. For example, you may implement this invention to the fire alarm which detects a flame with a pyroelectric element. As the circuit test, for example, the output level of the pyroelectric element when the test light is irradiated is monitored.

  Needless to say, the present invention can be applied to an alarm device other than a fire alarm device such as a gas leak alarm device.

  In the first embodiment, the voice stop switch that performs the operation of recognizing the language used is operated for 3 seconds or more as the operation of the voice stop switch for a predetermined time or longer. Otherwise, for example, the operation may be continued five times as a plurality of operations within a predetermined time.

  In the first embodiment, the language used is recognized at a specified timing (such as a voice stop switch operation). However, the language recognition unit 17 always recognizes the language used at a predetermined timing. The voice may be output in a language that is frequently used.

  In the first embodiment, the voice data is four languages, Japanese, English, Chinese, and Korean. However, the present invention is not limited to this. You may make it do.

  In the first embodiment, voice output is performed in one language. However, voice output may be performed alternately in Japanese and English, for example, in a plurality of languages.
