Description

  The present invention relates to an alarm device, for example, an alarm device that performs a fire alarm, a gas leak alarm, and the like.

  In recent years, development of a fire and gas leak combined type alarm device (fire / gas leak alarm device) having a function of detecting a gas leak at home and detecting a fire has been advanced. By the way, in such a fire / gas leak alarm device, it is conceivable that a failure of a fire sensor for detecting a fire or a gas sensor for detecting a gas leak occurs. If such a failure occurs, it is necessary to notify the fact of the failure with a fire / gas leak alarm.

  In addition to the above-described sensor, it is also conceivable that a predetermined electrical component such as an EEPROM that stores an alarm judgment value or the like built in the fire / gas leak alarm is broken. In this case as well, it is necessary to notify the fact of the failure using a fire / gas leak alarm.

  However, it is unclear which part the failure has occurred simply by notifying the failure, and even if the gas company comes to repair, it is not possible to know which part the failure has occurred and It is necessary to investigate the cause one by one. For this reason, even if a gas company came to the failure site, the cause of the failure could not be explained to the end user immediately, and the end user was anxious.

  Therefore, Patent Document 1 proposes a fire / gas leak alarm device for notifying the failure location when a failure is detected. According to the fire / gas leak alarm described in Patent Document 1, for example, the flashing cycle of a power lamp (LED that is turned on when power is supplied) is determined for the type of failure of the sensor and the power circuit (electrical part). The failure location is reported so as to be identifiable. However, in such failure location notification, there is a problem that it is difficult to intuitively determine the location where the failure has occurred because it is necessary to grasp the blinking cycle of the power lamp.

Patent Document 1 also describes that, for example, the following LED is blinked in accordance with the type of failure of the sensor and the power supply circuit unit (= electrical component) so that the failure location can be identified.
(1) Fire sensor failure: The fire indicator light that is lit in the event of a fire blinks.
(2) Gas sensor failure: The CO or CH ₄ indicator lamp that flashes when a gas is detected flashes (the flashing display differs from the flashing when a gas is detected).
(3) Power supply circuit unit failure: blink the power lamp.

According to such failure location notification, the fire indicator light flashes when the fire sensor fails, and the CO or CH ₄ indicator light blinks when the gas sensor fails, so it is intuitively determined where the failure has occurred. Becomes easy. However, even if the fire indicator light, CO or CH ₄ indicator light is blinking so that it can be distinguished from the time of fire or gas detection, the end user will recognize that the fire indicator light, CO or CH ₄ indicator light is emitted. There is a high possibility of misrecognizing the failure location notification as a fire or gas leak alarm.

Let us know the location of the failure. Accordingly, when a failure of the first or second gas sensor is detected, the power light-emitting element emits light differently from when the power is supplied, so that the end user recognizes that a failure has occurred.

Therefore, when a failure of the gas sensor or a predetermined electrical component is detected, the power light-emitting element emits light differently from when the power is supplied, so that the end user recognizes that a failure has occurred. However, since the gas light emitting element is not emitting light at this time, it is not erroneously recognized as an alarm.

  As described above, according to the first aspect of the present invention, when a failure of the gas sensor or the fire sensor is detected, the power light-emitting element emits light differently from the power supply, so that the end user has failed. Recognize that. However, since the gas light emitting element or the fire light emitting element is not emitting light at this time, it is not erroneously recognized as an alarm.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing an embodiment of a fire / gas leak alarm device as an alarm device of the present invention, and FIG. 2 is an external view of the fire / gas leak alarm device shown in FIG. As shown in the figure, the fire / gas leak alarm includes a fire sensor 11 and a gas sensor 12. The fire sensor 11 and the gas sensor 12 are connected to a microcomputer (hereinafter referred to as μCOM) 10 and supply detection results to the μCOM 10.

The fire sensor 11 is, for example, a heat sensor or a smoke sensor, and an appropriate type is used as necessary. The gas sensor 12 is a semiconductor gas sensor that detects CH ₄ (methane), hydrogen (H ₂ ), and CO (carbon monoxide) in a distinguishable manner.

The fire / gas leak alarm device also includes a power lamp 13 (= power light emitting element) that emits light when power is supplied to the fire / gas leak alarm device, and a city gas alarm lamp 14 that emits light when H ₂ and CH _{4 are} detected. (= Gas light emitting element), an incomplete combustion warning lamp 15 (= gas light emitting element) that emits light when CO is detected, and a fire alarm lamp 16 (= fire light emitting element) that emits light when a fire is detected. The power lamp 13 described above comprises a light emitting diode (LED) that emits green light, the city gas alarm lamp 14 comprises an LED that emits red light, the incomplete combustion alarm lamp 15 comprises an LED that emits yellow light, and a fire alarm lamp. Reference numeral 16 is an LED that emits red light. Each of the lamps 13 to 15 is connected to the μCOM 10 and the emission control is performed by the μCOM 10.

The fire / gas leak alarm device also includes an EEPROM 17 (= electrical parts, recording means), a voice confirmation switch 18 (= operating means), and a speaker 19. The EEPROM 17 stores, for example, CH ₄ , CO, and H ₂ alarm points. As shown in FIG. 2, the voice confirmation switch 18 is a switch that is turned on when the string 18a pulled out from the bottom surface of the casing is pulled. By turning on the voice confirmation switch 18, the voice confirmation switch 18 Notification and the like can be performed. The speaker 19 outputs an alarm sound and synthesized sound. These EEPROM 17, speaker 18, and voice confirmation switch 19 are connected to μCOM 10.

  The above-described μCOM 10 includes a central processing unit (CPU) 10a that performs various processes according to a program, a ROM 10b that is stored in a processing program performed by the CPU 10a, a work area that is used in various processes in the CPU 10a, and various data. And a ROM 10c which is a readable / writable memory having a data storage area for storing the data.

  The operation of the fire / gas leak alarm having the above-described configuration will be described below. First, when a power switch (not shown) is turned on and power is supplied to the fire / gas leak alarm, the CPU 10a turns on the power lamp 13. While the power is being supplied, the CPU 10a constantly lights the power lamp 13 to notify that the power is being supplied.

In response to the power supply, the CPU 10a uses the gas sensor 12 to detect the gas concentrations of CH ₄ , CO, and H ₂ . When the detected CH ₄ and H ₂ concentrations exceed the alarm point stored in the EEPROM 17, the CPU 10 a determines that a gas leak has occurred and uses the city gas alarm lamp 14 and the speaker 19 to generate city gas. Perform an alarm. The city gas alarm is performed in two stages, and the first stage (when the concentration is low) causes the city gas alarm lamp 14 to blink slowly at a cycle of 0.54 seconds. In the second stage (high concentration), the city gas lamp 14 is always lit and flash lighting is performed once every 0.54 seconds for 0.018 seconds (10 times the current is applied to light up with high brightness). Further, a double alarm using a sound / buzzer is performed using the speaker 19.

  Further, when the detected CO concentration exceeds the alarm point stored in the EEPROM 17, the CPU 10a determines that incomplete combustion has occurred and uses the incomplete combustion alarm lamp 15 and the speaker 19 to perform incomplete. Perform a combustion alarm. The incomplete combustion alarm is also performed in two stages, and the first stage (when the concentration is low) causes the incomplete combustion alarm lamp 15 to blink slowly at a cycle of 0.54 seconds. In the second stage (during high concentration), the incomplete combustion alarm lamp 15 is always turned on and the flash is turned on once every 0.54 seconds for 0.018 seconds. Further, a double alarm using a sound / buzzer is performed using the speaker 19. Note that even if the CO concentration is low, it is dangerous to be exposed for a long time, so if the state where the CO concentration exceeds the first alarm point continues for 13 minutes or more, the alarm moves to the second alarm.

  The CPU 10a determines that a fire has occurred when the ambient temperature or the amount of smoke detected by the fire sensor exceeds the alarm point, and issues a fire alarm using the fire alarm lamp 16 and the speaker 19. In the fire alarm, the fire alarm lamp 16 is always turned on and the flash is turned on once every 0.54 seconds for 0.018 seconds. Further, a double alarm using a sound / buzzer is performed using the speaker 19.

  Further, the CPU 10a functions as first failure detection means and monitors the output of the gas sensor 12 to determine whether or not a failure of the gas sensor 12 has occurred. Further, the CPU 10a functions as second failure detection means, and determines whether or not a failure has occurred in the fire sensor 11 or the EEPROM 17 by monitoring the output of the fire sensor 11 or accessing the EEPROM 17. Any known method may be used for determining the failure. When the failure determination of the fire sensor 11, the gas sensor 12, and the EEPROM 17 is detected by the failure determination described above, the CPU 10a starts a failure notification process for notifying the failure.

  A processing procedure of the CPU 10a in the failure notification process described above will be described below with reference to FIG. First, the CPU 10a functions as a failure notification unit, and changes the power lamp 13 from a constantly lit state to a high-speed blinking state (period 0.18 seconds) (step S1). The end user recognizes that a failure of the fire / gas leak alarm has occurred due to the transition from the constantly lit state of the power lamp 13 to the fast flashing state, and contacts the gas company.

  Thereafter, when the gas company arrives at the site and pulls the string 18a to turn on the voice confirmation switch 18 (Y in step S2), the CPU 10a detects a failure of the fire sensor 11 (Y in step S3). Then, the fire alarm lamp 16 is flashed at a high speed (cycle: 0.18 seconds) (step S5) to notify that the failure location is the fire sensor 11, and then the failure notification process is terminated. On the other hand, when a failure of the gas sensor 12 is detected (Y in step S4), the city gas alarm lamp 14 and the incomplete combustion alarm lamp 15 are simultaneously blinked at high speed (step S6), and the failure location is the gas sensor 12. Is notified, and the failure notification process is terminated.

  If a failure is detected in the EEPROM 17 (N in step S4), the failure notification process is immediately terminated and only the power lamp 13 continues to blink.

  According to the above-described fire / gas leak alarm device, when a failure of the fire sensor 11, the gas sensor 12, or the EEPROM 17 is detected, the power lamp 13 is changed from a constantly lit state to a high-speed blinking state so that it emits light differently from power supply. Therefore, the end user can recognize the occurrence of the failure. However, since the city gas alarm lamp 14, the incomplete combustion alarm lamp 15 and the fire alarm lamp 16 are not lit at this time, the end user does not misrecognize the failure notification as an alarm.

  Thereafter, when the gas company arrives at the site and turns on the voice confirmation switch 18, the fire alarm lamp 16 is detected when a failure of the fire sensor 11 is detected, and the city gas alarm lamp 14 and the incomplete combustion alarm lamp 15 are detected when a failure of the gas sensor 11 is detected. However, when the failure of the EEPROM 17 is detected, the power lamp 13 blinks, so that it is possible to intuitively grasp where the failure has occurred. Therefore, the failure location can be grasped intuitively, and the failure location notification is not erroneously recognized as an alarm.

  Further, according to the above-described fire / gas leak alarm device, the blinking lamps 13 to 16 are extinguished after one minute has passed since the various lamps 13 to 16 are blinked in order to notify the failure location. Therefore, the state where the city gas alarm lamp 14, the incomplete combustion alarm lamp 15, and the fire alarm lamp 16 are flashing indefinitely after the voice confirmation switch 18 is turned on is avoided, and the end user operates the city gas after the operation. It is possible to prevent the flashing of the alarm lamp 14, the incomplete combustion alarm lamp 15, and the fire alarm lamp 16 from being erroneously recognized as an alarm.

  Further, when the gas sensor 12 fails, the city gas alarm lamp 14 and the incomplete combustion alarm lamp 15 are simultaneously flashed in response to the ON operation of the voice confirmation switch 18, thereby further confirming that the failure location is the gas sensor 11. It can be grasped intuitively.

  Further, according to the above-described embodiment, after the fire alarm lamp 16, the city gas lamp 14, the incomplete combustion alarm lamp 15, and the power lamp 13 are flashed at high speed and the failure location is notified, the failure notification processing is terminated. The high-speed flashing was continued. However, especially in the case of a battery-type alarm device, if the blinking of the lamp is continued, the remaining battery level may become zero. Further, even after the operation, if the fire alarm lamp 16, the city gas lamp 14, and the incomplete combustion alarm lamp 15 continue to blink, the end user may erroneously recognize the alarm. Therefore, for example, when one minute (= predetermined time) has elapsed since the voice confirmation switch 18 was turned on, the CPU 10a may turn off the lamps 13 to 16 blinked at high speed.

  In the above-described embodiment, the electrical component has been described as an EEPROM as a recording unit. However, for example, any electrical component may be used as long as it is mounted on, for example, a fire / gas leak alarm, and may be a power supply circuit unit or the like.

  In addition, as embodiment mentioned above, it applied to the gas leak alarm which detects methane and CO so that identification is possible with one gas sensor. However, for example, it can be considered that the present invention is applied to a gas leak alarm that detects methane and CO with separate gas sensors. In this case, the CPU 10a functions as first gas and second gas failure detection means, detects failure for each of the methane sensor and the CO sensor (= first gas sensor, second gas sensor), and fails in the methane sensor or CO sensor. Is detected, the power lamp 13 is changed from the constantly lit state to the fast lit state. Then, when the voice recognition switch 18 is turned on, if a failure of the methane sensor is detected, the city gas alarm lamp 14 (= first gas light emitting element) blinks at high speed, and a failure of the CO sensor is detected. In such a case, it is conceivable that the incomplete combustion alarm lamp 15 (= second gas light emitting element) blinks at high speed to notify whether the failure location is a methane sensor or a CO sensor.

  Further, as the above-described embodiment, the case where the present invention is applied to a fire / gas leak alarm device that performs a fire alarm and a gas leak alarm has been described. However, for example, it may be applied to a gas leak alarm that does not perform a fire alarm. Such a gas leak alarm device detects only a single gas, or detects a plurality of types of gas, but does not use a single gas sensor such as the semiconductor gas sensor described above. Some have only a single gas sensor. In this case, the CPU 10a detects a failure with respect to an electrical component such as a gas sensor or an EEPROM, and when the failure of the gas sensor or the electrical component is detected, the power lamp 13 is changed from the constantly lit state to the fast lit state. Thereafter, when the voice recognition switch 18 is turned on, if a gas sensor failure is detected, the lamp that emits light at the time of gas detection flashes at high speed. If a failure of an electrical component is detected, the power lamp 13 is turned on. It is conceivable to flash at high speed to notify whether the failure location is the gas sensor 12 or an electrical component.

  In addition, some gas leak alarms that do not perform a fire alarm include one in which two or more gas sensors are incorporated, such as one that detects methane and CO with separate methane sensors and CO sensors, respectively. In this case, when the voice recognition switch 18 is turned on, the CPU 10a blinks the city gas alarm lamp 14 at a high speed when a failure of the methane sensor is detected, and is not activated when a failure of the CO sensor is detected. The complete combustion warning lamp 15 is blinked at high speed and only a notification is made as to whether the failure location is a methane sensor or a CO sensor.

It is a block diagram which shows one Embodiment of the fire and gas leak alarm of this invention. It is an external view of the fire / gas leak alarm device shown in FIG. It is a flowchart which shows the process sequence of CPU10a in a failure alerting | reporting process.
