Description

The present invention relates to an audio output system provided with an audio output unit that outputs audio.

In such an audio output system, when an event occurs that requires audio data such as disaster prevention information or climate information to be output as audio, the audio data corresponding to the event is sent to the audio output unit, and the audio output unit outputs the audio data. By outputting data by voice, the content of an event such as disaster prevention information or weather information that has occurred is communicated to the user (see, for example, Patent Document 1).

When an event such as disaster prevention information or climate information occurs, the user may not be near the audio output unit, and even if the audio data is output as audio, the content of the event may not be conveyed to the user. Therefore, in the system described in Patent Document 1, a human detection unit capable of detecting whether or not a person exists in the detection area is provided, and when an event requiring voice output of audio data occurs, the human presence detection unit is provided. On the condition that the feeling detection unit detects a person, the audio output unit outputs the audio data as audio.

JP 2020-155956 A

In the system described in Patent Literature 1, the human detection unit only detects whether or not a person exists in the detection area. is present, it is assumed that the human detection unit has detected a person, and the audio data is output as audio.

However, event contents include event contents for adults that should be transmitted to adults, and conversely, event contents for children that should be transmitted to children. Therefore, for example, when a child is present in the detection area, even if the event content for adults is output by voice, the event content for adults cannot be transmitted to the adult. Further, even if the content of the event is the same, there is a possibility that children, for example, cannot understand the content of the event depending on how the audio data is output. Thus, in the system described in Patent Document 1, there is a possibility that the event content cannot be transmitted to the person to whom it should be transmitted, and there is room for improvement in this respect.

In view of this situation, the main object of the present invention is to determine whether a person is an adult or a child when a person exists in the detection area, and to generate appropriate event information for both the adult and the child. To provide an audio output system capable of conveying contents.

A first characteristic configuration of the present invention includes a first infrared light projecting part that projects infrared rays toward a first detection area that is an upper area of the expected human presence area, and an infrared light that is incident from the direction of the first detection area. a first infrared sensor section having a detectable first infrared detection section;
A second infrared light projecting section that projects infrared rays toward a second detection area that is a lower side area of the expected human presence area, and a second infrared detection section that can detect infrared rays incident from the direction of the second detection area. a second infrared sensor unit having
A person who determines whether or not a person exists in the expected human presence area based on the information detected by the first infrared detector and the second infrared detector, including whether the person is an adult or a child. a determination unit;
an audio output unit that outputs audio;
a control unit for controlling the operating state of the audio output unit;
In a state in which an event requiring the voice output of voice data to be output by the voice output unit has occurred, when the person determination unit determines that a child exists in the planned human presence area, the control unit outputs a voice message for children. Performing voice output control for children to operate the voice output unit so as to perform voice output,
When the person determination unit determines that an adult exists in the expected human presence area, the control unit performs voice output control for adults to operate the voice output unit so as to output voices for adults. The point is that it is configured to

If there is no person in the detection area, the infrared rays projected from the infrared projection unit are reflected by the floor of the detection area, etc., and are detected by the infrared detection unit. amount) remains constant. On the other hand, if a person exists in the detection area, the infrared light projected from the infrared light projecting section will be reflected by the person, and the intensity of the infrared light detected by the infrared detecting section will increase. . As a result, whether or not the detection value of the infrared detection unit has increased is detected. For example, when the detection value of the infrared detection unit becomes larger than a set comparison reference value, it is determined that a person exists in the detection area. can be done.

In general, children are shorter than adults. Therefore, if a child is present in the planned human presence area, infrared rays are reflected by the child in the lower area of the planned human presence area, but the infrared rays are reflected by the child in the upper area of the expected human presence area. The area is such that no infrared rays are reflected by the child. On the other hand, if an adult exists in the expected human presence area, infrared rays will be reflected by the adult in both the lower area and the upper area of the expected human presence area.

Therefore, according to this configuration, the first infrared sensor section having the upper side area of the expected human presence area as the first detection area, and the second infrared sensor section having the lower side area of the expected human presence area as the second detection area. and As a result, the first detection value of the first infrared detection unit in the first infrared sensor unit and the second infrared detection unit in the second infrared sensor unit can A difference will occur for the second detected value of . By catching the difference in the detected values, the person determination unit can determine whether or not a person exists in the expected presence area, including whether the person is an adult or a child.

When an event occurs and the person determination unit determines that a child exists in the expected human presence area, the control unit performs voice output control for children to transmit the details of the event that should be transmitted to the child. can do. In addition, when an event occurs and the human determination unit determines that an adult exists in the expected human presence area, the control unit performs audio output control for adults to detect the event to be transmitted to the adult. Content can be conveyed. Therefore, appropriate event contents can be transmitted to both adults and children.

In the second characteristic configuration of the present invention, the first detection area and the second detection area are set in a state in which a part of the first detection area and a part of the second detection area overlap in the vertical direction,
The person determination unit determines that a child exists in the expected human presence area when the presence of a person is not detected in the first detection area and the presence of a person is detected in the second detection area,
In a state where the presence of a person is detected in both the first detection area and the second detection area, when the second detection value of the second infrared detection section is greater than the first detection value of the first infrared detection section, the human Determine that the child exists in the expected existence area,
In a state where the presence of a person is detected in both the first detection area and the second detection area, when the first detection value of the first infrared detection unit is equal to or greater than the second detection value of the second infrared detection unit, the human The point is that it is determined that an adult exists in the expected existence area.

For example, when setting the first detection area and the second detection area without overlapping, it is necessary to set the boundary between the first detection area and the second detection area so that there is no gap and the second detection area does not overlap. The operation of setting the first detection area and the second detection area is very troublesome.

Therefore, according to this configuration, the first detection area and the second detection area are set so that part of the first detection area overlaps part of the second detection area in the vertical direction. It is possible to appropriately detect a person in the expected human presence area while simplifying the work of setting the areas of the first detection area and the second detection area.

The person determination unit not only determines that a child exists in the expected human presence area, but also performs the first detection when the presence of a person is not detected in the first detection area and the presence of a person is detected in the second detection area. Even if the second detection value of the second infrared detection section is greater than the first detection value of the first infrared detection section in a state where the presence of a person is detected in both the region and the second detection region, the human Since it is determined that the child exists in the planned presence area, it can be appropriately determined that the child exists in the planned presence area. Further, the person determination unit detects the presence of a person in both the first detection area and the second detection area, and the first detection value of the first infrared detection unit is the second detection value of the second infrared detection unit. In this case, it is determined that an adult exists in the expected human presence area, so it can be appropriately determined that an adult exists in the expected human presence area.

Therefore, when a person exists in the detection area, it can be appropriately determined whether the person is an adult or a child. , and appropriate event contents can be conveyed to both adults and children.

In the third characteristic configuration of the present invention, the event contents in the event include event contents for children and event contents for adults,
When the event content of the event that has occurred is for children, the control unit executes the child-oriented audio output control until the person determination unit determines that a child exists in the planned human presence area. is prohibited, and when the person determination unit determines that a child exists in the planned person presence area, the voice output control for children is executed,
When the content of the event that has occurred is for adults, the control unit executes the audio output control for adults until the person determination unit determines that an adult exists in the planned person presence area. is prohibited, and when the human determination unit determines that an adult exists in the expected human presence area, the audio output control for adults is executed.

According to this configuration, when the event content of the event that has occurred is for children, when the person determination unit determines that a child exists in the planned person presence area, the control unit performs voice output control for children. to convey child-friendly event content to children. On the other hand, when the content of the event that has occurred is for adults, when the person determination unit determines that an adult exists in the planned person presence region, the control unit executes audio output control for adults. , the content of events for adults can be communicated to adults. Accordingly, regardless of whether the event content is for children or for adults, appropriate event content can be transmitted to both adults and children.

An embodiment of an audio output system according to the present invention will be described based on the drawings.
When an event occurs that requires audio data such as disaster prevention information and climate information to be output as audio, this audio output system outputs audio data corresponding to the event as audio, enabling various types of information such as weather information and disaster prevention information to be output. It conveys information to users.

As shown in FIG. 1, this voice output system 100 is configured using an alarm device 1 installed in a facility such as a user's residence. As shown in FIG. A unit 18 is provided to notify users in facilities such as residences of event contents.

As shown in FIG. 1, the voice output system 100 includes, in addition to the alarm device 1, a terminal device 2 such as a smartphone for the user to perform various settings and operations, a server device 3 for performing various control and communication, An external device 4 or the like is provided for notifying the occurrence of an event or the like. Each of the alarm device 1, the terminal device 2, and the external device 4 is configured to freely communicate various information with the server device 3 via an information communication network 5 such as the Internet.

The alarm device 1, as shown in FIG. there is The alarm device 1 includes a monitoring sensor unit 14, a person determination unit 15, a temperature/humidity sensor unit 16, a display unit 17, an audio output unit 18, a device-side control unit 19, a device-side storage unit 20, a device-side communication unit 21, and the like. It is

Various information for operating the alarm device 1 is stored in the device-side storage unit 20, and the device-side control unit 19 uses the various information stored in the device-side storage unit 20 to issue an alarm. It controls the operating state of the device 1 . The device-side control unit 19 is configured to be able to transmit and receive various types of information to and from the server device 3 through wired communication or wireless communication via the device-side communication unit 21 .

The monitoring sensor unit 14 includes various sensors such as a gas leak monitoring sensor, a CO (carbon monoxide) monitoring sensor, and a fire monitoring sensor. , gas leaks, CO concentration abnormalities, fires, etc. are monitored.

For example, when the concentration of the detection target gas detected by the gas leak monitoring sensor reaches or exceeds a set value, the device-side control unit 19 determines that there is a gas leak by displaying on the display unit 17 or by outputting sound from the sound output unit 18. Alarm for gas leak. In addition, when the CO concentration detected by the CO monitoring sensor exceeds the set value, the device-side control unit 19 determines that the CO concentration is abnormal, and displays the CO concentration by displaying on the display unit 17 or by outputting audio from the audio output unit 18. Issue an alarm for anomalies. Furthermore, when the fire monitoring sensor detects smoke, heat, etc. caused by a fire, the device-side control unit 19 determines that there is a fire, and issues a fire alarm through display by the display unit 17 and audio output by the audio output unit 18. I do.

The temperature/humidity sensor unit 16 detects the temperature and humidity of an indoor space such as a kitchen including the expected human presence area 13 . The display unit 17 has lamps and LEDs, and is configured by a display device capable of displaying character information and the like. The audio output unit 18 is composed of, for example, a speaker or the like, and is configured to be capable of outputting various kinds of audio data.

As shown in FIG. 1, the server device 3 includes a server-side control section 51, a server-side storage section 52, a server-side communication section 53, and the like. Various types of information are stored in the server-side storage unit 52, and the server-side control unit 51 controls the operating state of the server device 3 using the various types of information stored in the server-side storage unit 52. ing. The server-side control unit 51 is configured to be capable of various transmissions and receptions with the alarm device 1 and the external device 4 by wired communication or wireless communication via the server-side communication unit 53 .

The external device 4 is configured to notify the server device 3 of the occurrence of an external event such as disaster prevention information or climate information. For example, in the case of disaster prevention information, the external device 4 notifies the server device 3 of disaster prevention information such as "earthquake occurred" assuming that an event occurred at the timing of an earthquake. In the case of climate information, the external device 4 sends the updated weather forecast (for example, "Today's weather is sunny") to the server device assuming that an event has occurred at the timing when the weather forecast or the like is updated. 3 is notified.

In the server device 3, when receiving the notification that an event has occurred from the external device 4, the server-side control unit 51 acquires audio data corresponding to the event from the server-side storage unit 52, and stores the acquired audio data. It is sending to the alarm device 1. As a result, in the alarm device 1, the device-side control section 19 outputs the audio data transmitted from the server device 3 by the audio output section 18, thereby conveying the details of the event to the user.

For example, when an earthquake occurs, the server device 3 is notified of the occurrence of the earthquake from the external device 4, and the server-side control unit 51 stores voice data corresponding to the occurrence of the earthquake from the server-side storage unit 52. (audio data such as “earthquake occurred”) and transmits the audio data to the alarm device 1 . In the alarm device 1, the device-side control unit 19 causes the voice output unit 18 to output voice data such as "earthquake occurred" transmitted from the server device 3, thereby notifying the user that an earthquake has occurred. ing.

When the weather forecast is updated, the external device 4 notifies the server device 3 that the weather forecast has been updated, and the server-side control unit 51 updates the updated weather forecast from the server-side storage unit 52. Corresponding voice data (voice data such as "Today's weather is fine") is acquired, and the voice data is transmitted to the alarm device 1. FIG. In the alarm device 1, the device-side control unit 19 uses the voice output unit 18 to output voice data such as "Today's weather is fine" transmitted from the server device 3, and uses the updated weather forecast. communicated to people.

In this manner, in the audio output system 100, when an event occurs outside by the control units such as the server-side control unit 51 and the device-side control unit 19, the information corresponding to the event is sent to the external device 4→ Communication is performed in the order of the server device 3 →alarm device 1, and voice output control is performed to output voice data corresponding to the event from the voice output unit 18. FIG. For example, climate information is not limited to weather forecasts, but it is also possible to voice output "rain clouds approaching" at the timing when rain clouds are approaching, or output "weather warning issued" at the timing when a weather warning is issued. can also

The content of events in voice output control is not limited to disaster prevention information and climate information. Audio data corresponding to traffic information can also be output as audio, and various event contents can be applied.

In this audio output system 100, not only when an event occurs outside but also when an event occurs inside the facility, the controller such as the device-side controller 19 outputs audio data corresponding to the event. is output from the audio output unit 18 as audio output control. Since the voice output system 100 uses the alarm device 1 that monitors events to be monitored such as gas leaks, CO concentration abnormalities, and fires, it is possible to warn of monitored events such as gas leaks, CO concentration abnormalities, and fires. When an event is detected by the apparatus 1 , the audio output unit 18 outputs audio data corresponding to the monitored event assuming that an event has occurred.

For example, as shown in FIG. 2, when the device-side control unit 19 detects the occurrence of a gas leak based on the detection information of the monitoring sensor unit 14, the device-side control unit 19 determines that an event has occurred and displays a gas leak message such as "gas leak occurrence". is obtained from the apparatus-side storage unit 20, and the audio output unit 18 outputs the audio data corresponding to the gas leakage such as "gas leakage". In addition, even when the device-side control unit 19 detects an abnormality in the CO concentration or the occurrence of a fire, the device-side control unit 19 acquires audio data corresponding to them from the device-side storage unit 20, and outputs the acquired audio data to the audio output unit 18. Audio output.

The alarm device 1 includes not only the monitoring sensor section 14 but also a temperature and humidity sensor section 16 that detects the temperature and humidity of the indoor space including the expected human presence area 13 . Therefore, based on the information detected by the temperature and humidity sensor unit 16, the device-side control unit 19 determines whether there is a possibility that the temperature and humidity in the indoor space will rise and heatstroke or the like will occur, and It is determined whether the temperature and humidity environment of the indoor space is in an abnormal state, such as whether the humidity is low and the room is in a dry state.

When the device-side control unit 19 determines that the temperature and humidity environment in the indoor space is in an abnormal state, the device-side control unit 19 acquires audio data corresponding to the abnormal state of the temperature and humidity environment from the device-side storage unit 20, and acquires the audio data. The resulting audio data is output as audio by the audio output unit 18 . At this time, as the voice data corresponding to the abnormal temperature and humidity environment, if there is a possibility of heat stroke, etc., voice data such as "heat stroke caution" , and voice data such as "Caution for dryness".

Further, for example, voice data of fixed phrases such as "Today is trash day" is stored in the server-side storage unit 52 or the device-side storage unit 20, and the date and time for outputting voice data of the fixed phrases can be set. can be set. As a result, the control units such as the server-side control unit 51 and the apparatus-side control unit 19, when the set date and time come, assume that an event has occurred, and output voice data of fixed phrases such as "Today is garbage day." Audio output control for outputting audio from the output unit 18 can also be performed.

The occurrence of an event is a prerequisite for the audio output system 100 to perform audio output control. can be set as appropriate.

Since the event may not occur at the timing intended by the user, the content of the event cannot be communicated to the user if the audio output system 100 only performs audio output control in accordance with the occurrence of the event. can be difficult. Therefore, in the voice output system 100, after confirming that a person exists in the expected human presence area 13, voice output control is performed in response to the occurrence of an event.

The voice output system 100 is provided with a person determination unit 15 for determining whether or not a person exists in the expected person presence area 13 . The human judgment unit 15 not only judges whether or not a person exists in the planned human presence area 13, but also judges whether the person is an adult or a child.

In order for the person determination unit 15 to determine whether or not a person exists in the expected person presence area 13, including whether the person is an adult or a child, as shown in FIG. Two infrared sensor units, 31 and a second infrared sensor unit 41, are provided.

The first infrared sensor unit 31, as shown in FIGS. 2 to 5, includes a first infrared light projecting unit 32 that projects infrared light toward a first detection region 13a that is an upper region of the expected human presence region 13. , and a first infrared detector 33 capable of detecting infrared rays incident from the direction of the first detection region 13a. On the other hand, the second infrared sensor unit 41 includes a second infrared light projecting unit 42 that projects infrared rays toward the second detection area 13b that is the area below the expected human presence area 13, and and a second infrared detector 43 capable of detecting infrared rays incident from any direction.

The first infrared light projection unit 32 and the second infrared light projection unit 42 have the same configuration, and include a light emitting element capable of projecting infrared rays, and an irradiation range and an irradiation angle of the infrared light projected from the light emitting element. An optical lens or the like that can adjust the The first infrared detection unit 33 and the second infrared detection unit 43 have the same configuration, are sensitive to infrared rays, and are photoelectric conversion elements capable of outputting electrical signals corresponding to the intensity of the received infrared rays. etc. is provided.

As shown in FIGS. 3 to 5, the first infrared sensor section 31 and the second infrared sensor section 41 have the same configuration with the only difference being their detection areas. As for the detection area, the first infrared sensor unit 31 detects the first detection area 13a, which is the upper side area of the expected human presence area 13, while the second infrared sensor unit 41 detects the area of the expected human presence area 13. The second detection area 13b is the lower area.

For example, when no person exists in the expected human presence area 13 , the infrared rays projected from the first infrared light projecting unit 32 and the second infrared light projecting unit 42 are projected onto the floor 11 around the expected human presence area 13 . etc., and detected by the first infrared detection section 33 and the second infrared detection section 43 . Therefore, the infrared detection values detected by the first infrared detection section 33 and the second infrared detection section 43 are substantially constant. On the other hand, when a person exists in the expected human presence area 13 , the infrared rays projected from the first infrared light projecting unit 32 and the second infrared light projecting unit 42 are emitted from the person existing in the expected human presence area 13 . , and detected by the first infrared detector 33 and the second infrared detector 43 . Therefore, the intensity of the infrared rays detected by the first infrared detection section 33 and the second infrared detection section 43 is increased, and the detection value of the infrared rays detected by the first infrared detection section 33 and the second infrared detection section 43 is also increased. will increase. Therefore, the human determination unit 15 detects how the detection values of the infrared rays detected by the first infrared detection unit 33 and the second infrared detection unit 43 change, and determines whether a person exists in the expected human presence area 13 . It determines whether it exists or not.

In addition, the person determination unit 15 not only determines whether or not a person exists in the expected person presence area 13, but also determines whether the person is an adult or a child. In general, children are shorter than adults, so if child B is present in the expected human presence area 13 as shown in FIG. is reflected, but the infrared rays are not reflected by the child B in the upper region of the expected human presence region 13 . On the other hand, as shown in FIG. 3, if an adult A is present in the expected human presence area 13, infrared rays are reflected by the adult A in both the lower side area and the upper side area of the expected human presence area 13. FIG.

In this way, the first detection value of the first infrared detection section 33 and the second infrared sensor section of the first infrared sensor section 31 are obtained when the child B is present and when the adult A is present in the expected human presence area 13 . A difference occurs in the second detection value of the second infrared detection unit 43 in 41 . Therefore, the human determination unit 15 determines whether a person exists in the expected human presence area 13 by detecting the difference between the first detection value and the second detection value. It is determined including whether it is

Here, as shown in FIGS. 3 to 5, the first detection region 13a and the second detection region 13b overlap a part of the first detection region 13a and a part of the second detection region 13b in the vertical direction. set in the state. For this reason, for example, whether an adult A exists in the expected human presence area 13 (see FIG. 3) or a child B exists (see FIG. 4), either the first detection area 13a or the second detection area 13b The presence of a person is also detected. It cannot be determined whether an adult or a child exists in the expected human presence area 13 .

Therefore, the human determination unit 15 detects not only whether the presence of a person is detected in the first detection area 13a and the second detection area 13b, but also the first detection value of the first infrared detection unit 33 and the second infrared detection unit 43. It is determined whether an adult or a child exists in the planned person presence area 13 by comparing the size relationship with the second detection value of .

As shown in FIG. 5, the person determination unit 15 detects the presence of a child B in the expected human presence area 13 when the presence of a person is not detected in the first detection area 13a and the presence of a person is detected in the second detection area 13b. is determined to exist. Regarding the detection of the presence or absence of a person, if the first detection value of the first infrared detection unit 33 and the second detection value of the second infrared detection unit 43 are larger than the comparison reference value (threshold value), the human determination unit 15 Detects the presence of people.

Incidentally, the human determination unit 15 repeatedly performs the operation of detecting the presence or absence of a person based on the detection values of the first infrared detection unit 33 and the second infrared detection unit 43 at a set period (for example, 1 second). When the presence of a person is detected continuously (for example, three times), it is determined that the presence of a person is present, and the determined value is output to the server device 3 or the like. Further, when the presence of a person is not detected continuously for a set period of time (for example, one minute), the person determination unit 15 determines that no person exists, and outputs the determined value to the server device 3 or the like. ing.

As shown in FIG. 4, the human determination unit 15 detects the presence of a person in both the first detection area 13a and the second detection area 13b, and the second detection value of the second infrared detection unit 43 is the second detection value. 1, when it is larger than the first detection value of the infrared detection unit 33, it is determined that the child B is present in the expected person presence area 13. FIG. Conversely, as shown in FIG. 3, the person determination unit 15 detects the presence of a person in both the first detection area and the second detection area, and the first detection value of the first infrared detection unit 33 is When it is equal to or greater than the second detection value of the second infrared detector 43, it is determined that the adult A is present in the expected human presence area 13. FIG.

In this way, the part (volume or area) occupied by the existence range differs between the case where a child exists in the expected human presence area 13 and the case where an adult exists in the first detection area 13a and the second detection area 13b. By using this, the person determination unit 15 compares the magnitude relationship between the first detection value of the first infrared detection unit 33 and the second detection value of the second infrared detection unit 43, determines whether there are children or adults in

The event contents of the event include event contents for children and event contents for adults. For example, the contents of an event for children can be a message to a child who has just returned home, such as "Your mother is out at XX, so please stay home. There are snacks in the refrigerator." , It's time to go to cram school." Various types of information to be communicated to adults, such as news on stock prices and traffic information, can also be applied to the content of events for adults.

When the content of the event that has occurred is for children, the control units such as the server-side control unit 51 and the device-side control unit 19 cause the human determination unit 15 to determine whether a child exists in the planned human presence area 13. Execution of the voice output control for children is prohibited until it is determined that it is, and when the person determination unit 15 determines that a child exists in the planned human presence area 13, the voice output control for children is performed.

For example, the terminal device 2 is designed so that an event for children such as "Mom is out at ○○, so please stay home. There are snacks in the refrigerator." can be set in advance by using, for example, In this case, when it is time for the child to return home, an event with an event content for the child will occur. When the person determination unit 15 determines that a child exists in the planned human presence area 13 in a state where the event for children has occurred, the control units such as the server-side control unit 51 and the device-side control unit 19 The voice output control for children is performed so that the voice output unit 18 outputs the contents of the event for children such as "Mom is out at XX, so please stay home. Snacks are in the refrigerator." Run. Further, in a state where an event having event contents for children has occurred, the control units such as the server-side control unit 51 and the apparatus-side control unit 19 determine that a child exists in the planned human presence area 13 by the human determination unit 15. Until then, the execution of voice output control for children is prohibited.

When the content of the event that has occurred is for adults, the control units such as the server-side control unit 51 and the device-side control unit 19 control the person determination unit 15 as in the case of the event content for children. Until it is determined that an adult exists in the planned human presence area 13, execution of the voice output control for adults is prohibited. Execute control. At this time, for example, when news such as stock prices is updated and an event with event contents for adults occurs, the control units such as the server-side control unit 51 and the device-side control unit 19 output the news such as stock prices by voice. Adult-oriented audio output control is executed so that the output unit 18 outputs audio.

In this way, if the content of the event that has occurred is for children, the control units such as the server-side control unit 51 and the device-side control unit 19 confirm that a child exists in the planned human presence area 13 and then Then, the audio output control for children is performed so that the contents of the event for children are output as audio by the audio output unit 18 . On the other hand, if the content of the event that has occurred is for adults, the control units such as the server-side control unit 51 and the device-side control unit 19 confirm that an adult exists in the expected human presence area 13 and then Then, the audio output control for adults is performed so that the content of the event for adults is output as audio by the audio output unit 18 . This makes it possible to transmit appropriate event details to both adults and children.

The event content is not limited to the event content for children and the event content for adults, but also includes the event content for both children and adults. For example, disaster prevention information, climate information, etc. can be applied as event contents for both children and adults.

When the content of the event that has occurred is for both children and adults, the control units such as the server-side control unit 51 and the device-side control unit 19 cause the human determination unit 15 to determine the human presence planned region 13 When it is determined that a person (including a child and an adult) exists in the event, audio output control is performed so that the event content is output as audio by the audio output unit 18 . In addition, the control units such as the server-side control unit 51 and the device-side control unit 19 continue to perform voice output control until the human determination unit 15 determines that a person (including a child and an adult) exists in the expected human presence area 13. prohibited from running. As a result, even when the event content is for both children and adults, after confirming that people including children and adults exist in the person presence scheduled area 13, voice output control is performed, Appropriate event contents can be transmitted to people including children and adults.

The operation of the audio output system 100 will be described below based on the flowchart of FIG.
As shown in FIG. 6, in the voice output system 100, when an event occurs, the control units such as the server-side control unit 51 and the device-side control unit 19 determine whether the event content is for children. (If Yes in step #1, step #2). When the event content is for children, when the human determination unit 15 determines that a child exists in the planned human presence area 13, the control units such as the server-side control unit 51 and the device-side control unit 19 control the child's event content. oriented audio output control is executed (if Yes in step #2, if Yes in step #3, step #4).

When the human determination unit 15 determines that no child exists in the expected human presence area 13, the control units such as the server-side control unit 51 and the device-side control unit 19 prohibit execution of voice output control for children. Then, the process returns to step #3, and the person determining unit 15 determines whether or not a child exists in the expected human presence area 13 (if No in step #3, step #5).

If the content of the event that has occurred is for adults, when the person determination unit 15 determines that an adult exists in the planned person presence area 13, the control units such as the server-side control unit 51 and the device-side control unit 19 , adult audio output control is being executed (if Yes at step #6, if Yes at step #7, step #8).

When the human determination unit 15 determines that no adult exists in the expected human presence area 13, the control units such as the server-side control unit 51 and the device-side control unit 19 prohibit execution of voice output control for adults. Then, the process returns to step #7, and the person determining unit 15 determines whether or not an adult exists in the expected human presence area 13 (if No in step #7, step #9).

If the content of the event that has occurred is for both children and adults, and the human determination unit 15 determines that a person exists in the expected human presence area 13, the server-side control unit 51 and the device-side control unit 19 , etc., perform audio output control so that the event content is output as audio by the audio output unit 18 (in the case of Yes in step #10, in the case of Yes in step #11, in step #12 ).

When the person determining unit 15 determines that no person exists in the expected human presence area 13, the control units such as the server-side control unit 51 and the device-side control unit 19 prohibit execution of voice output control, Returning to step #11 again, the person determining unit 15 determines whether or not a person exists in the expected human presence area 13 (if No in step #11, step #13).

[Another embodiment]
Another embodiment of the present invention will be described. It should be noted that the configuration of each embodiment described below is not limited to being applied alone, and can be applied in combination with the configurations of other embodiments.

(1) In the above embodiment, the audio output system 100 is configured using the alarm device 1, but not limited to the alarm device 1, for example, any audio output device having the audio output unit 18 The type of device to be used can be changed as appropriate.

(2) In the above embodiment, the server device 3 is provided. However, the server device 3 can be omitted by, for example, providing the device-side control unit 19 or the like with various functions of the server-side control unit 51. .

(3) In the above embodiment, the event content of the event includes event content for children and event content for adults, as well as event content for both purposes. It is also possible to have only event content for adults and event content for adults.

(4) In the above embodiment, the control units such as the server-side control unit 51 and the device-side control unit 19 perform audio output control for children when an event for children occurs, and the event for adults is performed. By performing the adult-oriented audio output control when the content event occurs, the event in which the child-oriented audio output control is performed and the event in which the adult-oriented audio output control is performed are treated as different events.

Alternatively, the event for performing audio output control for children and the event for performing audio output control for adults may be the same event. In this case, when the human judgment unit 15 judges that a child exists in the planned human presence area 13, it is possible to perform voice output control for children by changing the words and contents to be voice-output for children. can. Also, when the person determining unit 15 determines that an adult exists in the expected human presence area 13, it is possible to perform voice output in a state where the words and contents to be voice-output are changed for adults as voice output control for adults. In this way, even if the event has the same event content, it is possible to change the wording and content of the voice output between the voice output control for children and the voice output control for adults.
