Description

The present invention provides a monitoring sensor unit that detects a monitoring target event, a voice output unit that outputs a sound, and a voice output unit when it is determined that a monitoring target event exists based on the detection result of the monitoring sensor unit. The present invention relates to an alarm device that includes an operation control unit that can operate in an alarm determination mode for informing the presence of a monitored event from a power supply unit that can supply power to a monitoring sensor unit, a voice output unit, and an operation control unit.

In Patent Document 1 (Japanese Patent Laid-Open No. 2002-269657), there is a monitoring target event (the detection output that detects the presence of the detected gas exceeds a predetermined alarm level) based on the detection result of the monitoring sensor unit. There is described an alarm device configured to determine whether or not the monitoring target event is present and to notify the presence of the monitoring target event from the audio output unit when it is determined that the monitoring target event is present. In addition, in Patent Document 1, for example, when the power is turned on after the alarm device is installed, the installer artificially supplies gas that is detected by the monitoring sensor unit, and the monitoring sensor unit monitors the gas. It is described to check whether the target event can be detected normally. It should be noted that this alarm device is configured such that the inspection operation state is started when the power is turned on, and the inspection end mechanism is activated when a preset period (for example, 240 seconds) has elapsed since the power was turned on. There is.

JP 2002-269657A

In the alarm device described in Patent Document 1, the inspection operation state automatically ends even if the installer does not artificially supply the gas detected by the monitoring sensor unit. In other words, the alarm device can operate in the alarm determination mode (“normal state” in Patent Document 1) even if it is not checked whether the monitoring sensor unit can normally detect the monitored event.

The present invention has been made in view of the above problems, and an object thereof is to provide an alarm device that is used after it is confirmed that a monitoring sensor unit can normally detect a monitored event.

The characteristic configuration of the alarm device according to the present invention for achieving the above object is a monitoring sensor unit for detecting a monitoring target event,
A voice output section for outputting voice,
When it is determined that the monitoring target event is present based on the detection result of the monitoring sensor unit, an operation control unit operable in an alarm determination mode for informing the presence of the monitoring target event from the voice output unit, ,
An alarm device comprising a power supply unit capable of supplying power to the monitoring sensor unit, the voice output unit, and the operation control unit,
The operation control unit,
After the power supply from the power supply unit is started, it operates in the event monitoring verification mode for verifying whether the monitoring sensor unit operates normally,
After it is determined that the monitoring sensor unit operates normally in the event monitoring verification mode, it operates in the alarm determination mode.

According to the above characteristic configuration, the operation control unit verifies whether or not the monitoring sensor unit normally operates before operating in the alarm determination mode after the power supply from the power supply unit is started. Operates in supervisory verification mode. That is, the operation in the alarm determination mode is not performed unless it is confirmed that the monitoring sensor unit operates normally in the event monitoring verification mode.
Therefore, it is possible to provide the alarm device used after it is confirmed that the monitoring sensor unit can normally detect the monitored event.

Another characteristic configuration of the alarm device according to the present invention is that the operation control unit is configured such that an output of the monitoring sensor unit is below a predetermined reference value while the operation control unit is operating in the event monitoring verification mode. The point is that it is determined that the monitoring sensor unit operates normally when a transition is made to a state larger than the reference value.

If an alarm device installer artificially generates a monitored event while the operation control unit of the alarm device is operating in the event monitoring verification mode (for example, the detection target gas is artificially blown to the alarm device). If the monitoring sensor unit is normal, the output of the monitoring sensor unit transits between a state below a predetermined reference value and a state above a predetermined reference value. On the other hand, when the alarm device installer does not artificially generate the monitored event, the output of the monitoring sensor unit is between a state below a predetermined reference value and a state above the reference value. Does not transition. If the monitoring sensor unit does not operate normally, the output of the monitoring sensor unit may be below a predetermined reference value even if the alarm device installer artificially causes the monitored event. Does not transition between states greater than the reference value.
Therefore, in this characteristic configuration, when the operation control unit is operating in the event monitoring verification mode, the output of the monitoring sensor unit transitions between a state below a predetermined reference value and a state above a predetermined reference value. , It is determined that the monitoring sensor unit operates normally. As a result, before the alarm device is used, the installer or the like can reliably confirm that the monitoring sensor unit can normally detect the monitored event.

Yet another characteristic configuration of the alarm device according to the present invention is that the operation control unit artificially generates the monitored event at a predetermined timing while operating in the event monitoring verification mode. The point is that the prompting voice is output from the voice output unit.

According to the above-mentioned characteristic configuration, it is possible to prompt the person who installs the alarm device to artificially generate the monitored event.

Still another characteristic configuration of the alarm device according to the present invention is that the operation control unit outputs a voice indicating that the operation in the event monitoring verification mode has been normally completed from the voice output unit.

According to the above characteristic configuration, it is possible to inform the installer of the alarm device that the operation in the event monitoring verification mode has been normally completed.

An object detection sensor according to an embodiment of the present invention and an alarm device 10 including the same will be described below with reference to the drawings.
FIG. 1 is a diagram showing a configuration of an alarm device 10 of the first embodiment including an object detection sensor. As shown in the figure, the alarm device 10 has a monitoring sensor unit 15 for detecting a monitoring target event, a voice output unit 20 for outputting a voice, and a monitoring target event based on the detection result of the monitoring sensor unit 15. When it is determined that the voice output unit 20 notifies the presence of the monitored event, the control unit 14 as an operation control unit operable in the alarm determination mode, the monitoring sensor unit 15, the voice output unit 20, and the control unit 14 are provided. The housing 11 includes a power supply unit 16 capable of supplying electric power. In addition, the alarm device 10 of the present embodiment also includes, in the housing 11, a storage unit 18 that stores information handled by the alarm device 10, a display unit 19 that displays information provided to the user of the alarm device 10, and the like. .. The housing 11 of the alarm device 10 is installed on the side of the ceiling member 1 of the room 4 whose upper and lower sides are partitioned by the floor member 2 and the ceiling member 1.

The operation of the alarm device 10 (alarm determination mode) will be described below.
The monitoring sensor unit 15 is configured to include, for example, a gas leak monitoring sensor, a CO (carbon monoxide) monitoring sensor, a fire monitoring sensor, and the like. The detection result of the monitoring sensor unit 15 is transmitted to the control unit 14. When the monitoring sensor unit 15 has a gas leak monitoring sensor, the monitoring target event detected by the monitoring sensor unit 15 is that the detection target gas exists at a predetermined level or higher. When the monitoring sensor unit 15 has a CO monitoring sensor, the monitoring target event detected by the monitoring sensor unit 15 is that CO is present at a predetermined level or higher. When the monitoring sensor unit 15 has a flame monitoring sensor, it means that smoke, light, heat, or the like generated due to a fire exists.

The gas leak monitoring sensor is configured by using a methane gas monitoring sensor for detecting the concentration of methane gas (CH ₄ ) which is the main component of city gas, when using city gas as the detection target gas, for example. When another gas is to be detected, a sensor that can detect that gas may be used. Then, the control unit 14 determines whether or not a gas leak has occurred (that is, whether or not the gas concentration to be detected is equal to or higher than a predetermined level) based on the detection result transmitted from the gas leak monitoring sensor. judge.

The CO monitoring sensor is configured by using a gas sensor for detecting the concentration of carbon monoxide gas (CO). Then, the control unit 14 determines whether or not the concentration of carbon monoxide is equal to or higher than a predetermined level, based on the detection result transmitted from the CO monitoring sensor.

The fire monitoring sensor can be realized by using, for example, a sensor that detects the light of flame, a sensor that detects the smoke generated by the fire, a sensor that detects the heat generated by the flame, or the like. .. Then, the control unit 14 determines whether or not a fire has occurred, based on the detection result transmitted from the fire monitoring sensor.

The power supply unit 16 is composed of, for example, a battery. Alternatively, the power supply unit 16 is configured by a power receiving unit that receives electric power supplied from the electric power system and converts the electric power into a desired voltage or the like. Further, the alarm device 10 is provided with a power switch 17 that receives an operation input by the user. Then, when the power-on operation is performed on the power switch 17, power is supplied to each part of the alarm device 10, and when the power-off operation is performed, the power supply to each part of the alarm device 10 is cut off.

The audio output unit 20 provided in the housing 11 is realized by using a speaker or the like that can output audio. A voice message is stored in advance in the storage unit 18, and when the control unit 14 determines that a monitoring target event exists based on the detection result of the monitoring sensor unit 15, the monitoring target event exists. A voice message to the effect is read from the storage unit 18 and the voice output unit 20 notifies it.

The display unit 19 provided on the housing 11 is a lamp realized by using an LED or the like, or a display device capable of displaying character information. Display pattern information for turning on/off the lamp and character information examples to be displayed are stored in the storage unit 18 in advance, and the control unit 14 determines that a monitoring target event exists based on the detection result of the monitoring sensor unit 15. When it is determined that the monitoring target event exists, the display pattern information or the character information example indicating that the monitored event exists is read from the storage unit 18 and output from the display unit 19.

In addition, the alarm device 10 includes an object detection sensor. When the object detection sensor is mounted on the alarm device 10, the presence of a person can be detected by the object detection sensor. Then, a voice message can be output from the alarm device 10 while a person is present in the detection area 3. The object detection sensor of this embodiment has an infrared emission unit 12 that emits infrared rays toward a predetermined detection region 3, an infrared detection unit 13 that can detect infrared rays incident from the direction of the detection region 3, and is set in advance. A control unit 14 as an operation control unit operable in a presence/absence determination mode that determines whether or not an object is present in the detection area 3 based on a comparison result between a reference value and a detection value of the infrared detection unit 13; The infrared emission unit 12, the infrared detection unit 13, and the control unit 14 are provided with a power supply unit 16 capable of supplying electric power. The detection area 3 is set inside the room 4.

The infrared emitting section 12 has a light emitting element that can emit infrared rays, for example. Further, the infrared emitting unit 12 may have an optical element such as a lens that limits the irradiation range of the infrared rays so that the infrared rays emitted by the light emitting elements are emitted toward the detection region 3.

The infrared detection unit 13 has, for example, a photoelectric conversion element that is sensitive to infrared rays and outputs an electric signal according to the intensity of the received infrared rays. At this time, if the light receiving surface of the photoelectric conversion element faces the detection area 3, infrared rays incident from the direction of the detection area 3 can be favorably detected by the photoelectric conversion element. Further, the infrared detection unit 13 may include an optical element such as a lens that collects infrared rays incident from the direction of the detection region 3 onto the light receiving surface of the photoelectric conversion element.
The electric signal output from the infrared detection unit 13 is transmitted to the control unit 14.

Next, the operation (presence/absence determination mode) of the object detection sensor mounted on the alarm device 10 will be described.
When the object detection sensor is operating, the infrared emission unit 12 emits infrared rays toward the detection region 3, and the infrared detection unit 13 receives infrared rays incident from the direction of the detection region 3. Then, the electric signal (detection value) output from the infrared detection unit 13 is transmitted to the control unit 14. At this time, even if an object that strongly reflects infrared rays (including a human body) does not exist in the detection area 3, for example, the infrared rays are also reflected by the floor member 2 included in the detection area 3. The infrared rays are continuously detected, and the electric signal according to the intensity of the infrared rays is continuously transmitted to the control unit 14.

That is, while the environment of the detection area 3 does not change, that is, while an object such as a person does not move in the detection area 3, the infrared detection value of the infrared detection unit 13 becomes a substantially constant value. On the other hand, when the environment of the detection area 3 changes, the infrared detection value by the infrared detection unit 13 should also change. In particular, when an object such as a person newly enters the detection area 3, the intensity of the infrared light reflected by the object and reaching the infrared detection unit 13 increases, and the detection value of the infrared detection unit 13 also increases. Therefore, the control unit 14 sets the reference value stored in the storage unit 18 and the detection value transmitted from the infrared detection unit 13 in the presence/absence determination mode for determining whether or not an object is present in the detection area 3. In comparison, if the detected value is equal to or larger than the predetermined reference value, it is determined that an object exists in the detection area 3 (that is, a new object has entered). On the other hand, if the detected value is smaller than the reference value, the control unit 14 determines that there is no object in the detection area 3 (that is, no new intrusion).

<Event monitoring verification mode of the monitoring sensor unit 15>
After the power supply from the power supply unit 16 is started, the alarm device 10 first operates in the event monitoring verification mode instead of the alarm determination mode described above. Specifically, the control unit 14 operates in the event monitoring verification mode for verifying whether the monitoring sensor unit 15 operates normally after the power supply from the power supply unit 16 is started, and the event monitoring verification mode. After it is determined that the monitoring sensor unit 15 operates normally, the operation is performed in the alarm determination mode. In this case, the control unit 14 monitors when the output of the monitoring sensor unit 15 transitions between a state of being less than or equal to a predetermined reference value and a state of being larger than the reference value while operating in the event monitoring verification mode. It is determined that the sensor unit 15 operates normally.

FIG. 2 is a flowchart illustrating the event monitoring verification mode of the monitoring sensor unit 15. After the power supply from the power supply unit 16 is started, the control unit 14 verifies whether or not the monitoring sensor unit 15 normally operates in step #11. For example, when the monitoring sensor unit 15 has a gas leak monitoring sensor, the installer of the alarm device 10 artificially sprays the detection target gas or the like toward the alarm device 10 during execution of the event monitoring verification mode. A monitoring target event. Alternatively, when the monitoring sensor unit 15 has a CO (carbon monoxide) monitoring sensor, the installer of the alarm device 10 artificially blows CO toward the alarm device 10 to artificially generate the monitored event. Let Alternatively, when the monitoring sensor unit 15 has a fire monitoring sensor, the installer of the alarm device 10 artificially emits smoke, light, heat, or the like similar to smoke, light, or heat generated by a fire. To cause the event to be monitored artificially.

Then, if the monitoring sensor unit 15 is operating normally, the output of the monitoring sensor unit 15 transmitted to the control unit 14 transits between a state below a predetermined reference value and a state above a predetermined reference value. Then, the control unit 14 determines that the monitoring sensor unit 15 operates normally when the output of the monitoring sensor unit 15 transitions between a state of being less than or equal to a predetermined reference value and a state of being larger than the reference value, and an event Exit the monitoring verification mode. Then, in step #13, the control unit 14 causes the voice output unit 20 to output a voice indicating that the operation in the event monitoring verification mode has been normally completed.

On the other hand, if the installer of the alarm device 10 has not artificially caused the monitoring target event, or if the monitoring target event has been artificially generated, the monitoring sensor unit 15 does not operate as described above. If it is not determined that the normal operation is performed, in step #12, the control unit 14 outputs a voice prompting to artificially generate the monitored event at a predetermined timing while operating in the event monitoring verification mode. The audio output unit 20 outputs the audio. Then, the control unit 14 verifies whether or not the monitoring sensor unit 15 normally operates in the process #11.

As described above, after the power supply from the power supply unit 16 is started, the alarm device 10 first operates not in the alarm determination mode but in the event monitoring verification mode, so that the monitoring sensor unit 15 operates normally. Whether or not it can be surely verified. Then, unless it is confirmed that the monitoring sensor unit 15 operates normally in the event monitoring verification mode, the operation in the alarm determination mode is not performed.

<Object detection verification mode of object detection sensor>
After the power supply from the power supply unit 16 is started, the alarm device 10 first operates in the object detection verification mode instead of the existence determination mode described above. Specifically, the control unit 14 operates in the object detection verification mode for verifying whether or not the presence or absence of the object in the detection area 3 can be normally determined after the power supply from the power supply unit 16 is started, After determining that the presence or absence of the object in the detection area 3 can be normally determined in the detection verification mode, the operation is performed in the presence determination mode. In this case, the control unit 14 is in a state where an object exists in the detection area 3 based on the comparison result between the reference value and the detection value of the infrared detection unit 13 while operating in the object detection verification mode. When both the state in which the object does not exist in the detection area 3 is confirmed, it is determined that the presence or absence of the object in the detection area 3 can be normally determined.

FIG. 3 is a flowchart illustrating the object detection verification mode of the object detection sensor. After the power supply from the power supply unit 16 is started, the control unit 14 verifies whether or not the presence/absence of an object in the detection area 3 can be normally determined in step #21. For example, the installer of the alarm device 10 equipped with the object detection sensor enters and exits the detection area 3 of the object detection sensor during execution of the object detection verification mode. Then, the control unit 14 determines whether the object exists in the detection region 3 or the object does not exist in the detection region 3 based on the comparison result between the reference value and the detection value of the infrared detection unit 13. You can see both. That is, the control unit 14 determines whether the object exists in the detection area 3 based on the comparison result between the reference value and the detection value of the infrared detection unit 13 while operating in the object detection verification mode. When both the state in which the object does not exist in the detection area 3 is confirmed, it is determined that the presence or absence of the object in the detection area 3 can be normally determined, and the object detection verification mode ends. Then, in step #23, the control unit 14 causes the voice output unit 20 to output a voice indicating that the operation in the object detection verification mode has been normally completed.

On the other hand, if the installer of the alarm device 10 has not yet entered or exited the detection area 3 of the object detection sensor, the control unit 14 operates in the object detection verification mode in step #22. The voice output unit 20 outputs a voice prompting a person to move between the detection area 3 and the detection area 3 at a predetermined timing. Then, the control unit 14 verifies again whether or not the presence or absence of the object in the detection region 3 can be normally determined in the process #21.

As described above, after the power supply from the power supply unit 16 is started, the alarm device 10 first operates in the object detection verification mode, not in the presence/absence determination mode, to thereby determine whether the object detection sensor operates normally. It can be surely verified. The operation in the presence/absence determination mode is not performed unless it is confirmed that the object detection sensor can normally determine the presence/absence of an object in the object detection/verification mode.

In the alarm device 10 of the first embodiment, after the power supply from the power supply unit 16 is started, one of the above-described event monitoring verification mode and object detection mode may be performed first, or the event monitoring verification mode. The object detection mode may be performed simultaneously in parallel.

<Second Embodiment>
The alarm device 10 of the second embodiment is different from the above-mentioned embodiment in that it has a communication function. The alarm device 10 according to the second embodiment will be described below, but the description of the same configuration as the above embodiment will be omitted.

FIG. 4 is a diagram showing the configuration of the alarm device 10 of the second embodiment including the object detection sensor. As shown in the figure, the alarm device 10 has a monitoring sensor unit 15 for detecting a monitoring target event, a voice output unit 20 for outputting a voice, and a monitoring target event based on the detection result of the monitoring sensor unit 15. When it is determined that the voice output unit 20 notifies the presence of the monitored event, the control unit 14 as an operation control unit that can operate in the alarm determination mode, the monitoring sensor unit 15, the voice output unit 20, and the control unit 14. The housing 11 includes a power supply unit 16 capable of supplying electric power. In addition, the alarm device 10 of the present embodiment also includes a communication unit 21, a storage unit 18 that stores information handled by the alarm device 10, a display unit 19 that displays information provided to the user of the alarm device 10, and the like. Prepared for the housing 11.

The communication unit 21 realizes a communication function by radio waves. By operating the communication unit 21, the alarm device 10 can perform information communication with other communication devices such as a wireless router. When the alarm device 10 includes the communication unit 21, the alarm device 10 receives the information of, for example, a voice message from another communication device, and the alarm device 10 is provided on condition that a person exists in the detection area 3. The alarm device 10 can be used such that the voice output unit 20 outputs the voice message. In that case, the voice message can be reliably transmitted to the person present in the detection area 3. However, even if the presence of a person in the detection area 3 can be detected, if the communication state between the communication unit 21 of the alarm device 10 and another communication device is not good, the alarm device 10 is The alarm device 10 cannot be used as described above because it cannot receive voice message information from other communication devices.
Therefore, in the present embodiment, as will be described later, the control unit 14 determines whether the communication state between the communication unit 21 and another communication device is good before operating in the presence/absence determination mode. It operates in the communication status determination mode.

FIG. 5 is a flowchart illustrating the event monitoring verification mode of the monitoring sensor unit 15, the object detection verification mode of the object detection sensor, and the communication state determination mode.
After the power supply from the power supply unit 16 is started, the control unit 14 verifies whether or not the presence/absence of an object in the detection area 3 can be normally determined in step #31. Similar to the above-described embodiment, the installer of the alarm device 10 equipped with the object detection sensor enters and leaves the detection area 3 of the object detection sensor during execution of the object detection verification mode. Then, in step #31, the control unit 14 determines that the object exists in the detection area 3 and the object exists in the detection area 3 based on the comparison result between the reference value and the detection value of the infrared detection unit 13. Since it is possible to confirm both of the states where the object is not present, it is determined that the presence or absence of the object in the detection area 3 can be normally determined. Then, in step #33, the control unit 14 causes the voice output unit 20 to output a voice to the effect that the communication state determination mode is entered. In other words, a person who hears this voice can recognize that the operation in the object detection verification mode has been completed normally, and therefore the voice to shift to the communication state determination mode is the operation in the object detection verification mode. It can be said that it is a voice indicating that the process has ended normally. However, the control unit 14 does not operate the object detection sensor in the presence/absence determination mode, even if the process #33 is terminated, unless the communication state determination mode described below is terminated.

In addition, when it is not determined in step #31 that the presence or absence of the object in the detection area 3 can be normally determined, that is, the installer of the alarm device 10 is still entering or exiting the detection area 3 of the object detection sensor. If not, in step #32, the control unit 14 causes the voice output unit 20 to output a voice prompting a person to move in order to enter and leave the detection area 3 of the object detection sensor. Then, the control unit 14 verifies again whether or not the presence or absence of the object in the detection region 3 can be normally determined in the process #31.

The control unit 14 performs the communication state determination mode after causing the voice output unit 20 to output a voice to the effect that the communication state determination mode is entered in step #33. That is, next in step #34, the control unit 14 determines whether the communication state between the communication unit 21 of the alarm device 10 and another communication device such as a wireless router is good. Then, if the communication state is good, in step #36, the control unit 14 causes the voice output unit 20 to output a voice to the effect that the communication state determination mode is ended.

On the other hand, when the communication condition is not good, that is, when the current installation location of the alarm device 10 cannot ensure good communication with other communication devices such as a wireless router, it is necessary to relocate the alarm device 10. It can be said that there is. Therefore, in step #35, the control unit 14 prompts the movement of the installation location of the object detection sensor when the communication state between the communication unit 21 and another communication device is not good in the communication state determination mode. Is output from the voice output unit 20.
Therefore, it is considered that the installer of the alarm device 10 moves the alarm device 10 to another place after stopping the power supply to the alarm device 10.

Through the series of steps as described above, the control unit 14 operates in the presence/absence determination mode for determining whether or not an object exists in the detection area 3 before the object detection sensor of the alarm device 10. Can confirm that the presence of an object can be normally detected, and that the communication state between the communication unit 21 of the alarm device 10 and another communication device such as a wireless router is good. That is, the control unit 14 of the alarm device 10 operates in the object detection verification mode and operates in the communication state determination mode before operating in the existence determination mode.

Next, the control unit 14 operates in the event monitoring verification mode. Specifically, the control unit 14 terminates the communication state determination mode due to the good communication state in step #36, and then determines whether the monitoring sensor unit 15 normally operates in step #37. To verify. For example, the installer of the alarm device 10 artificially blows a gas to be detected or the like toward the alarm device 10 to cause a monitored event. Then, if the monitoring sensor unit 15 is operating normally, the output of the monitoring sensor unit 15 transmitted to the control unit 14 transits between a state below a predetermined reference value and a state above a predetermined reference value. In other words, the control unit 14 determines that the monitoring sensor unit 15 operates normally when the output of the monitoring sensor unit 15 transitions between the state of being less than or equal to the predetermined reference value and the state of being larger than the reference value, and the event Exit the monitoring verification mode. Then, in step #39, the control unit 14 causes the voice output unit 20 to output a voice indicating that the operation in the event monitoring verification mode has been normally completed. Then, the control unit 14 outputs a voice when it is determined that the monitoring target event exists based on the detection result of the monitoring sensor unit 15 after determining that the monitoring sensor unit 15 operates normally in the event monitoring verification mode. It operates in the alarm determination mode in which the presence of the monitored event is notified from the unit 20.

On the other hand, if the installer of the alarm device 10 has not artificially caused the monitoring target event, or if the monitoring target event has been artificially generated, the monitoring sensor unit 15 does not operate as described above. If it is not determined that the normal operation is performed, the control unit 14 causes the voice output unit 20 to output a voice prompting to artificially generate the monitored event in step #38. Then, the control unit 14 verifies again whether the monitoring sensor unit 15 operates normally in step #37.
