(First operation example: When the visitor is judged to be a dangerous person)
Next, a first operation example of the intercom system 100 will be described with reference to FIGS. 3 and 4.
FIG. 3 is a flowchart for explaining a first operation example of the intercom system 100. FIG. 4 is a diagram showing an example of a display screen displayed on the display 6a of the smartphone 6.
In this operation example, an operation when a visitor approaches the front door and is picking will be described.

When the visitor approaches the predetermined range around the entrance, the camera 24 of the entrance slave unit 2 captures an image of the approaching visitor (step S10). The camera 24 may be a camera that is always set to an imaging state, or may be a camera that is activated in response to the movement of an object or the amount of heat to start imaging.

Further, when the visitor approaches the vicinity of the entrance, the microphone 23 of the entrance slave unit 2 collects the voice of the visitor or the sound generated by the visitor (step S11). The microphone 23 may be a microphone that is set to be capable of collecting sound at all times, or may be a microphone that is activated and starts collecting sound when the camera 24 starts imaging.

Next, the slave unit control unit 25 uses the image data of the visitor captured by the camera 24 and the voice data of the visitor collected by the microphone 23 as visitor information via the signal line L1 in the living room master unit. It is transmitted to 3 (step S12).

When the visitor information (image data and audio data) is received from the entrance slave unit 2, the action determination unit 41 in the master unit control unit 37 of the living room master unit 3 analyzes the received image data and audio data, and the visitor Acquire behavioral information regarding behavior (step S13).
The behavior information of the visitor includes, for example, information on behaviors such as an act of approaching the entrance door and picking, an act of continuously hitting the entrance door, an act of repeatedly pressing the call button, and an act of continuing to yell. Furthermore, in the behavior information of the visitor, for example, the act of going back and forth in front of the entrance, the act of staying in front of the entrance for a long time, and the resident side sounding a message confirmation message in response to pressing the call button. It may contain information about behaviors such as acts that are silent even if they are done. Further, the behavior information of the visitor may include information on the behavior such as pressing the call button while holding the luggage.

Next, the behavior determination unit 41 determines the degree of risk of the visitor's behavior based on the acquired behavior information (step S14). The risk level of behavior is set to, for example, five levels from risk level 1 to risk level 5. In the various behavior information of the visitor described above, for example, the act of pressing the call button while holding a baggage is determined to be a low-risk behavior and is set to a risk level of 1. The act of going back and forth in front of the entrance, the act of staying in front of the entrance for a long time, the act of being silent even if the resident confirms the message in response to pressing the call button, etc. are dangerous. Is judged to be a moderate behavior and is set to a risk level of 3. The act of approaching the front door and picking, the act of continuously hitting the front door, the act of repeatedly pressing the call button, the act of continuing to scream loudly, etc. are judged to be high-risk behaviors and are set to a risk level of 5. There is. In the case of this operation example, since the visitor's action is an act of approaching the entrance door and picking, the action determination unit 41 determines the risk level of the visitor's action as "risk level 5".

Next, the action determination unit 41 determines whether or not the risk level determined in step S14 is equal to or higher than the preset risk threshold value (step S15). In this example, the risk threshold is set to, for example, "risk level 4".

When it is determined in step S15 that the risk level of the visitor's behavior is not equal to or higher than the risk threshold value (No in step S15), the master unit control unit 37 ends the process. When the risk level of the visitor is smaller than the risk threshold value, for example, when the risk level is determined to be "danger level 3" or "danger level 1", the second operation example or the third operation example described later will be described. It will be described in detail in the operation example.

On the other hand, when it is determined in step S15 that the risk of action is equal to or higher than the risk threshold value (Yes in step S15), the response mode selection unit 42 of the master unit control unit 37 has a plurality of storage units 35 stored in the storage unit 35. Among the response modes, the danger response mode is selected as the response mode for responding to the visitor (step S16). In this operation example, it is determined that the risk level (“risk level 5”) of the visitor is equal to or higher than the risk threshold value, and the response mode selection unit 42 selects the risk response mode as the response mode. The behavior information of the visitor for whom the danger response mode is selected includes, for example, the act of continuously hitting the entrance door, the act of repeatedly pressing the call button, and the act of loudly, in addition to the act of approaching the entrance door and picking. The act of continuing to scream is included.

Next, the master unit control unit 37 reads a warning message from a plurality of messages stored in the storage unit 35 based on the selection of the danger response mode, and sends the warning message via the signal line L1. To the entrance slave unit 2 (step S17). Specifically, the master unit control unit 37 transmits a message such as "If the action is continued, the police (or the security company) will be notified" as a warning message to the entrance slave unit 2.

When the warning message is received from the living room master unit 3, the slave unit control unit 25 of the entrance slave unit 2 sends the received warning message (“If the action is continued, the police are notified”) from the speaker 22 to the visitor. Sound is emitted against the sound (step S18).

After sounding a warning message to the visitor, the master unit control unit 37 of the living room master unit 3 determines the behavior of the visitor based on the image data and audio data acquired from the entrance slave unit 2 in the action judgment unit 41. The behavior information is acquired, and the risk level of the visitor's behavior is determined based on the acquired behavior information (step S19). Although not shown in FIG. 3, the slave unit control unit 25 may resume imaging by the camera 24 and sound collection by the microphone 23 after emitting the warning message, or the camera 24 may resume sound collection by the microphone 23. The image pickup by the camera 23 and the sound collection by the microphone 23 may be continued at all times after steps S10 and S11. After emitting a warning message from the speaker 22 of the entrance slave unit 2, the master unit control unit 37 acquires the image data captured by the camera 24 and the audio data collected by the microphone 23 from the entrance slave unit 2, and these are obtained. Acquire the behavior information of the visitor after the warning message is sounded based on the data of.

Next, the behavior determination unit 41 determines whether or not the risk level of the visitor's behavior maintains the risk threshold value or higher even after the warning message is sounded (step S20).

In step S20, when it is determined that the risk level of the visitor's behavior does not maintain the risk threshold or higher, that is, when it is determined that the visitor has stopped picking the front door (No in step S20), the master unit The control unit 37 stops the sound generation of the warning message and ends the process.

On the other hand, in step S20, when it is determined that the risk level of the visitor's behavior maintains the risk threshold value or higher (Yes in step S20), the master unit control unit 37 urgently calls the smartphone 6 carried by the resident. A notification signal is transmitted (step S21). The emergency notification signal is a notification signal for notifying that the resident's house is in an emergency state.

When the smartphone 6 receives the emergency notification signal, the smartphone 6 can notify the police or the security company that it is in an emergency state and the image of the visitor captured by the camera 24 of the entrance slave unit 2 on the display 6a. The operation screen and is displayed (step S22). FIG. 4 shows an example of the captured image 61 displayed on the display 6a of the smartphone 6 and an example of the notification operation screen 62. When the reproduction button 61a displayed on the display 6a is pressed, the captured image is reproduced. A voice or the like related to a visitor collected by the microphone 23 of the entrance slave unit 2 may be added to the image to be reproduced.

Next, the smartphone 6 determines whether or not the report operation screen 62 has been pressed by the user (step S23). When it is determined that the report operation screen 62 is pressed (Yes in step S23), the smartphone 6 executes an emergency call to the police or the security company (step S24). As a result, the processing of this operation example is completed.

When the warning message is transmitted to the entrance slave unit 2 in step S17 and the warning message is emitted from the speaker 22 in step S18, the master unit control unit 37 is a signal indicating that the warning message is emitted to the visitor. May be transmitted to the smart speaker 7. In that case, the smart speaker 7 emits a response result message indicating the response result, such as "A warning message has been emitted because a visitor judged to be dangerous has arrived." To the resident. The response result may be reported. The smart speaker 7 may store the contents of the response result so that the resident can hear the response result message after returning home when the visitor is away.

If it is determined in step S20 that the risk level of the visitor's behavior does not maintain the risk threshold value or higher, the master unit control unit 37 stops sounding the warning message and notifies the visitor information. The signal may be transmitted to the smartphone 6. In this case, the display 6a of the smartphone 6 may show that a visitor with a high degree of risk has visited, that the emergency state has not been maintained, and the like.

In step S21, the destination to which the master unit control unit 37 transmits the emergency notification signal is not limited to the resident's smartphone 6, and is, for example, a terminal device owned by a security company, a terminal device owned by the police, or the like. May be good. Further, when the resident's house is an apartment house such as an apartment, the destination for transmitting the emergency notification signal by the master unit control unit 37 is the terminal device of the manager's room, the terminal device of the management company, or the like. There may be.

Further, in step S21, the master unit control unit 37 transmits an emergency notification signal to the resident's smartphone 6, and also displays the captured image 61 and the notification operation as shown in FIG. 4 on the display 36 of the living room master unit 3. The screen 62 may be displayed.

In the intercom system 100, various data transmitted and received between the living room master unit 3, the entrance slave unit 2, the smartphone 6 and the smart speaker 7 may be stored in an external cloud server.

(Second operation example: When the visitor is judged to be a suspicious person)
Next, a second operation example of the intercom system 100 will be described with reference to FIG. FIG. 5 is a flowchart for explaining a second operation example of the intercom system 100. In this operation example, the operation when a visitor moves back and forth in front of the entrance will be described.

Since steps S30 to S32 shown in FIG. 5 are the same as steps S10 to S12 in the flowchart shown in FIG. 3, detailed description thereof will be omitted.
Next, the master unit control unit 37 of the living room master unit 3 acquires the behavior information of the visitor in the behavior determination unit 41 (step S33). The behavior information of the visitor acquired in this operation example is the information that "the visitor is moving back and forth in front of the entrance."

Next, the action determination unit 41 of the master unit control unit 37 determines the degree of risk of the visitor's action based on the action information acquired in step S33 (step S34). In this operation example, since the behavior information of the visitor is the information that "the visitor is moving back and forth in front of the entrance", the behavior judgment unit 41 sets the risk level of the action as "risk level 3". judge. The behavior information of the visitor judged to be "risk level 3" corresponds to, for example, the act of staying in front of the entrance for a long time and the pressing of the call button, in addition to the act of going back and forth in front of the entrance. This includes acts that are silent even if a message confirming the message is emitted from the resident side.

Next, the action determination unit 41 determines whether or not the determined risk level is equal to or higher than the risk threshold value (“risk level 4”) (step S35).
In step S35, when it is determined that the risk level of the visitor's behavior is equal to or higher than the risk threshold value (Yes in step S35), the process proceeds to step S16 in FIG.

On the other hand, when it is determined in step S35 that the risk of the visitor's behavior is not equal to or higher than the risk threshold (No in step S35), the master unit control unit 37 determines that the risk of the visitor's behavior is equal to or higher than the suspicious threshold. It is determined whether or not there is (step S36). In this example, the suspicious threshold is set to, for example, "risk level 2".
If it is determined in step S36 that the risk of the visitor's behavior is not equal to or higher than the suspicious threshold value (No in step S36), the master unit control unit 37 ends the process. An operation example when the risk level of the visitor is smaller than the suspicious threshold value, for example, when the risk level is determined to be "risk level 1" will be described in detail in the third operation example described later.

On the other hand, when it is determined in step S36 that the risk of action is equal to or higher than the suspicious threshold value (Yes in step S36), the response mode selection unit 42 of the master unit control unit 37 responds to the visitor. The suspicious response mode is selected as (step S37). In this operation example, since the risk level of the visitor's behavior is "risk level 3", it is determined that the risk level is equal to or higher than the suspicious threshold value, and the suspicious response mode is selected.

Next, the master unit control unit 37 reads a warning message to be emitted to a suspicious visitor from the storage unit 35 based on the selection of the suspicious response mode, and reads the warning message via the signal line L1. To the entrance slave unit 2 (step S38). The master unit control unit 37 reads a message such as "Do you want something?" From the storage unit 35 as a warning message, and transmits the warning message to the entrance slave unit 2.

When the warning message is received from the living room master unit 3, the slave unit control unit 25 of the entrance slave unit 2 emits the received warning message (“Do you want something?”) From the speaker 22 to the visitor. (Step S39).

Next, the master unit control unit 37 transmits a suspicious person notification signal to the resident's smartphone 6 (step S40). The suspicious person notification signal is a notification signal notifying that a suspicious visitor has arrived and that a warning message has been sounded to the visitor.

The smartphone 6 that has received the suspicious person notification signal displays the suspicious person notification screen on the display 6a (step S41). In this case, the image captured by the visitor may be reproduced on the display 6a. As a result, the processing of this operation example is completed.

In this operation example, the master unit control unit 37 may transmit to the smart speaker 7 that a warning message has been emitted to the visitor. In that case, the smart speaker 7 emits a response result message indicating the response result, such as "A visitor who is determined to be a suspicious person has arrived, so a warning message has been emitted." Report the response result to.

(Third operation example: When the visitor is judged to be a normal person)
Next, a third operation example of the intercom system 100 will be described with reference to FIG. FIG. 6 is a flowchart for explaining a third operation example of the intercom system 100.
In this operation example, an operation when a courier (visitor) visits to deliver a package will be described.

Since steps S50 to S52 shown in FIG. 6 are the same as steps S10 to S12 in the flowchart shown in FIG. 3, detailed description thereof will be omitted.
Next, the master unit control unit 37 of the living room master unit 3 acquires the behavior information of the visitor in the behavior determination unit 41 (step S53). The behavior information of the visitor acquired in this operation example is the information that "the call button is pressed while holding the luggage" because the visitor is a courier.

Next, the action determination unit 41 of the master unit control unit 37 determines the degree of risk of the visitor's action based on the action information acquired in step S53 (step S54). In this operation example, since the behavior information of the visitor is the information that "the call button is pressed while holding the luggage", the behavior judgment unit 41 determines the risk level of the action as "risk level 1". .. In addition to the act of pressing the call button while holding the luggage, the behavior information of the visitor judged to be "risk level 1" includes, for example, the act of pressing the call button without holding the luggage. included.

Next, the action determination unit 41 determines whether or not the determined risk level is equal to or higher than the risk threshold value (“risk level 4”) (step S55).
When it is determined in step S55 that the risk level of the visitor's behavior is equal to or higher than the risk threshold value (Yes in step S55), the process proceeds to step S16 in FIG.

On the other hand, when it is determined in step S55 that the risk of the visitor's behavior is not equal to or higher than the risk threshold (No in step S55), the master unit control unit 37 determines that the risk of the visitor's behavior is the suspicious threshold (“No.”). It is determined whether or not the risk level is 2 ”) or higher (step S56).
When it is determined in step S56 that the risk of the visitor's behavior is equal to or higher than the suspicious threshold value (Yes in step S56), the process proceeds to step S37 in FIG.

On the other hand, in step S56, when it is determined that the risk of the visitor's behavior is not equal to or higher than the suspicious threshold value (No in step S56), the response mode selection unit 42 of the master unit control unit 37 responds to the visitor. The normal response mode is selected as the response mode of (step S57). In this operation example, since it is determined that the risk level of the visitor's action is "risk level 1" and not equal to or higher than the suspicious threshold value, the response mode selection unit 42 normally selects the response mode.

Next, the master unit control unit 37 generates a message confirmation message to be emitted to a normal visitor in the message generation unit 43 based on the selection of the normal response mode, and confirms the message. The message is transmitted to the entrance slave unit 2 via the signal line L1 (step S58). The message generation unit 43 generates a message such as "Which one? What is your business?" As a message confirmation message based on the message example on the resident side stored in the storage unit 35. do.

When the message confirmation message is received from the living room master unit 3, the slave unit control unit 25 of the entrance slave unit 2 sends the received message confirmation message ("Which one? What is your requirement?"). Sound is emitted from the speaker 22 to the visitor (step S59).
When the visitor responds to the message confirmation message, the entrance slave unit 2 transmits the visitor's response message to the living room master unit 3 (step S60).

When the response message is received, the master unit control unit 37 emits the response message from the speaker 32 and stores the response message in the storage unit 35 (step S61). Next, the master unit control unit 37 transmits the response message stored in the storage unit 35 to the smart speaker 7 (step S62).

When the response message is received from the living room master unit 3, the smart speaker 7 generates, for example, a message "The courier has come to deliver the package" as the visitor information, and emits the message (the message is emitted). Step S63). As a result, the processing of this operation example is completed.

In step S62, the master unit control unit 37 transmits the response message of the visitor to the smart speaker 7, but instead of or in addition to the visitor, the visitor notifies that the delivery company has come to deliver the package. The person notification signal may be transmitted to the resident's smartphone 6. In this case, the image captured by the visitor may be reproduced on the display 6a of the smartphone 6.
