Description

  The present invention relates to an alarm device that outputs a sound alarm when an alarm state is detected, such as a fire alarm device or a gas leak alarm device, and in particular, an alarm device that has a built-in seismic sensor and outputs a sound alarm even when an earthquake occurs. It is about.

  In a gas leak alarm that outputs a sound alarm when a gas leak condition is detected, when a gas meter is connected and the seismoscope built in the gas meter detects an earthquake and closes the internal shut-off valve, this is indicated. A message to be notified is output as a voice from a gas leak alarm to effectively use the voice output function of the gas leak alarm.

  However, since the gas leak alarm outputs a voice message to the effect that the shut-off valve is closed instead of the gas meter, it is limited to earthquakes with a certain large seismic intensity, so the voice message alerts the occurrence of the earthquake itself. It does not have a function.

Therefore, even if the gas meter does not reach the seismic intensity that closes the shut-off valve, the applicant has reported in the past that the gas meter should notify the user of the occurrence of an earthquake that requires attention. Proposed a technology that incorporates a seismic detector in the leak alarm itself and outputs a warning message even when an earthquake that does not occur until the shut-off valve is closed (for example, a patent) Reference 1).
JP 2002-230665 A

  However, the above-mentioned previous proposals of the applicant of the present application are mainly intended to notify not only the occurrence of an earthquake through the closing of the shut-off valve in the gas meter, but also the occurrence of an earthquake having a seismic intensity that does not lead to the shut-off of the shut-off valve. Therefore, the content of the notification is uniform, and it may not be the one that encourages appropriate actions and actions according to the occurrence of the earthquake, which is most important at the time of the earthquake. There wasn't.

  The present invention has been made in view of the above circumstances, and the object of the present invention is to enable the voice output function of an alarm device that outputs a sound alarm when a warning state is detected, such as a fire alarm device or a gas leak alarm device. It is intended to provide an alarm device that can be used to output a sound alarm that prompts appropriate actions and actions according to the occurrence of an earthquake separately from a sound alarm that is output when an alarm state that is originally detected occurs. .

  The alarm device of the present invention according to claim 1, which achieves the above object, is a seismic sensing means for detecting an earthquake in an alarm device that outputs a sound alarm when an alarm state is detected, as shown in the basic configuration diagram of FIG. 3 and an earthquake alarm output means 9A for outputting a sound alarm at the time of earthquake different from the sound alarm at the time of detection of the alarm state when the seismic sensing means 3 detects an earthquake, and the earthquake alarm output The means 9A is characterized in that the sound alarm at the time of earthquake is outputted in a different pattern according to the seismic intensity of the earthquake detected by the seismic sensing means 3.

  Further, the alarm device of the present invention described in claim 2 is the alarm device of the present invention described in claim 1, wherein the earthquake voice alarm is composed of one or a plurality of voice messages selected from a plurality of types. The earthquake warning output means 9A is configured to output the voice alarm at the time of the earthquake in different patterns by changing the selection contents of the voice message according to the seismic intensity of the earthquake detected by the seismic sensing means 3.

  Furthermore, the alarm device of the present invention described in claim 3 is the alarm device of the present invention described in claim 1 or 2, wherein the seismic alarm output means 9A has a seismic intensity detected by the seismic sensing means 3. The configuration is such that the output of the earthquake sound alarm is canceled when it falls below a predetermined threshold.

  According to the alarm device of the present invention described in claim 1, when the seismic sensing means 3 detects an earthquake, the earthquake differs in a pattern different depending on the detected seismic intensity and different from the voice alarm when the alarm state is detected. Since the hourly sound alarm is output by the earthquake alarm output means 9A, it is possible to output a sound alarm prompting appropriate action and action according to the situation of the occurred earthquake by effectively utilizing the sound output function of the alarm device. it can.

  Further, according to the alarm device of the present invention described in claim 2, in the alarm device of the present invention described in claim 1, the earthquake alarm output means 9A according to the seismic intensity of the earthquake detected by the seismic sensing means 3, Since the selection of one or more voice messages that make up the earthquake alarm is made different, the voice alarm that is output by effectively using the voice output function of the alarm is appropriate for the situation of the earthquake that occurred The content that prompts the action can be easily configured.

  As in the alarm device of the present invention described in claim 3, in the alarm device of the present invention described in claim 1 or 2, the seismic intensity of the earthquake detected by the seismic sensing means 3 is below a predetermined threshold value. In this case, if the earthquake warning output unit 9A cancels the output of the earthquake voice alarm, it is possible to prevent the earthquake voice alarm from being output even if the earthquake has a weak seismic intensity.

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

  FIG. 2 is a block diagram showing an electrical schematic configuration of a fire alarm device according to an embodiment of the present invention. The fire alarm device according to this embodiment includes a smoke sensor 1 for fire detection and a seismic detector 3. (Corresponding to the seismic means in the claims), a voice IC 5 that stores a plurality of voice messages that are output when a warning state is detected by the smoke sensor 1 and the seismic sensor 3, and a voice message that is stored in the voice IC 5 And a smoke sensor 1, a seismic device 3, a sound IC 5, and a microcomputer (hereinafter abbreviated as “microcomputer”) 9 for controlling the operation of the speaker 7.

  The seismoscope 3 detects irregular vibrations and generates an on / off pulse signal having a predetermined cycle at a length per unit time according to the seismic intensity, similar to a built-in microcomputer gas meter. Output.

  In addition to the voice message when a fire is detected by the smoke sensor 1 when the smoke sensor 1 detects a fire, the voice IC 5 outputs a sound from the speaker 7 when an earthquake is detected by the seismic device 3. The first voice message is “Earthquake, earthquake occurrence, ensuring safety”, the second voice message is “fire treatment, securing the evacuation route”, and the third voice message is “Evacuation, evacuation, falling objects attention” "Are stored respectively.

  The microcomputer 9 includes a CPU 9a, a RAM 9b, and a ROM 9c. Among these, the smoke sensor 1, the seismic sensor 3, the sound IC 5, and the speaker 7 are connected to the CPU 9a in addition to the RAM 9b and the ROM 9c.

  The RAM 9b has a data area for storing various data and a work area used for various processing operations, and the ROM 9c stores a control program for causing the CPU 9a to perform various processing operations.

  Next, processing relating to the sound output of the earthquake alarm performed by the CPU 9a according to the control program stored in the ROM 9c will be described with reference to the flowchart of FIG.

  When the program is started by starting the microcomputer 9, the CPU 9a first starts monitoring the occurrence of an earthquake by the seismic device 3 so that the vibration of the fire alarm device is not erroneously detected as an earthquake. For the initial delay (for example, 1 minute) waiting period (step S1), and after the waiting period has elapsed (Y in step S1), the pulse signal from the sensor 3 corresponding to the seismic intensity of 3 or more It is confirmed whether or not there is an input of 20 ms or more in 3 seconds (step S3).

  If there is no input of 20 ms or more in 3 seconds of the pulse signal (N in step S3), repeat step S3 until there is an input of 20 ms or more in 3 seconds, and if there is an input of 20 ms or more in 3 seconds (step In S3, Y), it is confirmed whether or not the input of the pulse signal from the seismic device 3 is 40 ms or more in 3 seconds, corresponding to the case where the seismic intensity is 5 or more (step S5).

  If the input of the pulse signal is not 40 ms or more in 3 seconds (N in step S5), the first voice message and the second voice message stored in the voice IC 5 are alternately repeated five times from the speaker 7. After outputting the sound (step S7), the process returns to step S3.

  On the other hand, if the input of the pulse signal from the seismic device 3 is 40 ms or more in 3 seconds (Y in step S5), the first voice message stored in the voice IC 5 is output as voice (step S9) It is confirmed whether or not the input of the pulse signal from the seismic device 3 has decreased to less than 10 ms in 3 seconds corresponding to the case where the seismic intensity is less than 2 (step S11).

  If the pulse signal input has not decreased to less than 10 ms in 3 seconds (N in step S11), the process returns to step S9, and if it has decreased to less than 10 ms in 3 seconds (Y in step S11), 1 minute The second voice message stored in the voice IC 5 is repeatedly output by voice (step S13), and then the third voice message stored in the voice IC 5 is repeatedly output for one minute (step S15). Subsequently, after the second voice message and the third voice message are alternately repeated over one minute and output from the speaker 7 (step S17), the process returns to step S3.

  As is clear from the above description, in the fire alarm according to the present embodiment, steps S3 to S17 in the flowchart of FIG. 3 are processes corresponding to the earthquake alarm output means in the claims.

  In the fire alarm device according to the present embodiment configured as described above, when the earthquake detected by the seismic device 3 is equivalent to a seismic intensity of 3 or more and less than 5, the first voice message and the second voice message. A low-seismic intensity pattern sound alarm is output from the speaker 7 by repeating 5 times alternately.

  If the earthquake detected by the seismic device 3 corresponds to a seismic intensity of 5 or more, the first voice message is repeated until the seismic intensity falls below 2 and then the second and third voice messages are received. Is repeated for 1 minute each, and finally, a high-seismic intensity pattern alarm warning in which the second and third voice messages are alternately repeated over 1 minute is output as sound from the speaker 7.

  For this reason, it is possible to output a sound alarm for prompting appropriate actions and actions according to each situation, in which the pattern differs depending on whether the earthquake that has occurred has a low seismic intensity or a high seismic intensity.

  In the fire alarm device according to the above-described embodiment, one that outputs a voice from the first to third voice messages stored in the voice IC 5 according to the seismic intensity of the earthquake detected by the seismic sensor 3 is used. In addition, by changing the voice output method of each voice message (for example, repeating independently or alternately with other voice messages), changing the voice output time length, etc., the patterns of individual voice alerts during earthquakes are made different.

  However, for example, in the case of seismic intensity 5, this voice message is changed, and in the case of seismic intensity 4, this voice message is changed so that the content of the voice output voice message itself is changed according to the seismic intensity of the earthquake detected by the shaker 3. It may be.

  In the fire alarm of the above-described embodiment, a case has been described in which a voice message is not output even if an earthquake with a seismic intensity of less than 3 is detected by the seismic sensor 3, but an earthquake with a seismic intensity of less than 3 is detected. It may be configured to output a voice message even when detected in step 3. The lower limit of the seismic intensity at which no voice message is output and the voice message pattern (combination, output method, voice output time length) , It may be configured to be arbitrarily set in advance.

  Furthermore, in the above-described embodiment, the fire alarm device has been described as an example. However, the present invention detects a gas leak state and notifies the alarm state by using a sound alarm output as an alarm state. Needless to say, the present invention is widely applicable to all alarm devices that output an audio alarm when a state is detected.

It is a basic lineblock diagram of an alarm device concerning the present invention. It is a block diagram which shows the electrical schematic structure of the fire alarm which concerns on one Embodiment of this invention. It is a flowchart which shows the process regarding the audio | voice output of the earthquake warning which CPU performs according to the control program stored in ROM of the microcomputer of FIG.
