In this embodiment, a case where the intercom system 1 is used in a condominium as the facility 5 will be described as an example.

The lobby intercom 10 is installed, for example, in a common area E1 such as a lobby of a condominium. The collective housing has a shared part E1 and a plurality of dedicated parts (households) E2. The walkie-talkie main unit 20 is provided in each dedicated unit E2 in the dedicated unit E2. The intercom sub-unit 30 is installed, for example, in the lobby outside the residence for each dedicated unit E2.

The hall intercom 10 and the intercom main unit 20 are configured to be able to communicate with each other via the control device 40 . Thereby, in the intercom system 1 of this embodiment, a call can be made between the lobby intercom 10 and the intercom main unit 20 . Furthermore, the intercom master 20 and the intercom slave 30 are configured to be able to communicate with each other.

The hall intercom 10 starts to take pictures of the visitor when the visitor performs a calling operation. When the hall intercom 10 accepts a call operation, it sends a control signal (call signal) for calling the resident in the dedicated section E2 to the intercom main unit 20 via the control device 40 . When the hall intercom 10 can communicate with the intercom main unit 20 through the operation on the intercom main unit 20 , the audio data including the audio of the visitor is sent to the intercom main unit 20 through the control device 40 . When the hall intercom 10 receives the voice data of the operator of the intercom main unit 20 through the control device 40, it outputs a voice (including the operator's audio) based on the received data.

In the hall intercom 10, either one of the suppression mode and the non-suppression mode is set as the setting mode. The suppression mode is a mode for suppressing an output sound from a sound (input sound) input from a predetermined direction. The non-suppression mode is a mode in which the output sound is not suppressed for the sound input from a pre-designated direction (input sound). When the hall intercom 10 is set with the suppression mode, when the audio data including the visitor's audio is sent to the intercom host 20, the output sound is suppressed for the input sound from the designated direction. When the hall intercom 10 is set with the non-suppression mode, when the audio data is sent to the intercom host 20, the suppression of the output sound of the input sound from the designated direction is not performed.

In the state where the intercom main unit 20 receives the control signal (call signal) from the hall intercom 10 (in other words, the state where there is a call from a visitor via the hall intercom 10), the resident in the dedicated section E2 communicates with the hall intercom 10 Or the unlocking operation of the door 51 of the hall.

When the control device 40 receives a control signal (call signal) from the hall intercom 10, it sends it to the intercom host 20 that has a call.

Furthermore, the control device 40 locks and unlocks, for example, the door 51 provided in the common part E1 according to the operation of the intercom main unit 20 .

The intercom sub-unit 30 transmits a control signal (call signal) for calling a resident in the dedicated section E2 to the intercom main unit 20 when receiving an operation for calling from a visitor. The intercom sub-unit 30 sends audio data to the intercom main unit 20 when it is possible to communicate with the intercom main unit 20 by operating the intercom main unit 20 . When the intercom sub-unit 30 receives the audio data including the audio of the operator of the intercom main unit 20, it outputs the audio (including the audio of the operator) based on the received data.

(2) Composition (2-1) Hall intercom As shown in FIG. 1 , the lobby intercom 10 includes an imaging unit 11 , a communication unit 12 , an operation unit 13 , a sound pickup unit 14 , an output unit 15 , and a control unit 16 . In addition, the lobby intercom 10 includes a housing 10A (see FIG. 3A ).

The lobby intercom 10 includes, for example, a microcomputer having a processor and a memory. And, the processor executes the program stored in the memory, whereby the microcomputer functions as the control unit 16 . Here, the program executed by the processor is pre-recorded in the memory of the microcomputer, but it may also be provided on a non-transitory recording medium such as a memory card, or provided through an electric communication line such as the Internet.

The imaging unit 11 has imaging elements such as two-dimensional image sensors such as CCD (Charge Coupled Devices, charge-coupled device) image sensors, or CMOS (Complementary Metal-Oxide Semiconductor, complementary metal oxide semiconductor) image sensors, and uses A camera that takes pictures of subjects (visitors, etc.). In this embodiment, the imaging area (field of view) of the imaging unit 11 is set to the front of the hall intercom 10 so that at least the face of the visitor can be captured. In addition, in the present embodiment, the imaging unit 11 is a camera that captures moving images, but may also be a camera that captures still images. Furthermore, in this embodiment, the image pickup unit 11 is a camera that takes a color image, but may also be a camera that takes a black-and-white image.

The communication unit 12 includes a communication interface for communicating with the walkie-talkie host 20 via the control device 40 . The communication part 12 is configured in such a way that two-way communication can be performed between the intercom hosts 20, so that voice data and control signals can be bidirectionally transmitted between the hall intercom 10 and the intercom host 20.

The operation unit 13 accepts an operation for calling from a visitor. If a specific operation (such as a pressing operation) is performed on the operation part 13, a control signal (call signal) for calling the occupants in the dedicated part E2 (household) will be sent to the intercom main unit 20 via the communication part 12 and the control device 40.

The sound pickup unit 14 has a plurality of microphones. The plurality of microphones are omnidirectional microphones. In this embodiment, there are two microphones (first microphone 141, second microphone 142) as shown in FIG. 2A and FIG. 2B. The first microphone 141 and the second microphone 142 pick up the surrounding sound including the audio of the person (visitor) operating the operation unit 13 , convert the picked up sound into a sound signal representing sound data, and output it to the control unit 16 . Furthermore, in the present embodiment, the second microphone 142 picks up sound when performing the suppressing function.

The output unit 15 is, for example, a speaker. The output unit 15 outputs the sound (including the operator's audio) based on the audio data sent from the intercom main unit 20 when the hall intercom 10 is in a state where the intercom main unit 20 can communicate.

As shown in FIGS. 2A and 2B , the control unit 16 has a setting unit 161 , a first removal unit 162 , a switching unit 163 , a suppression unit 164 , a second removal unit 165 , and a processing unit 166 .

The control unit 16 has a suppression mode and a non-suppression mode, and any one of the suppression mode and the non-suppression mode is set as a setting mode at the time of a call.

The setting unit 161 sets either one of the suppression mode and the non-suppression mode in the storage unit 17 as the setting mode.

Specifically, when the hall intercom 10 is installed in the shared unit E1, the setting unit 161 sets either the suppression mode or the non-suppression mode as the setting mode in the memory unit 17 as part of the installation work. When the suppression mode is set to the setting mode during setup, the direction to pick up the input sound to be suppressed can be specified. When receiving direction information related to the direction in which the input sound to be suppressed is picked up, the setting unit 161 sets the direction indicated by the direction information. In this embodiment, at least one of the right direction B2 and the left direction B3 is specified with respect to the front direction (first direction) B1 of the housing 10A in the state where the hall intercom 10 (casing 10A) is installed. For example, when there is a door 51 entering from the shared part E1 to the dedicated part E2 in the right direction B2 (see FIG. 3A ), roads and the like exist in the left direction B3. Therefore, road noise and the like are generated from the left direction B3. If road noise is generated when calling, it may be difficult for the resident to hear the caller's audio. Therefore, when the hall intercom 10 is installed, the setting unit 161 accepts the setting of the suppression mode and designates the left direction B3 as the direction to be suppressed by the operator's operation. The setting unit 161 sets (memorizes) the accepted suppression mode and the direction of the suppression object in the storage unit 17 . Thereby, the hall intercom 10 can be set as follows, that is, the output sound of the sound picked up from the area E10 (refer to FIG. The output sound for the sound picked up from the area E11 (refer to FIG. 3B ) corresponding to the left direction B3 is suppressed. In the following description, when the suppression mode is set to the setting mode, the direction to be suppressed is designated as the left direction B3.

Furthermore, when the suppression mode is set to the setting mode, the hall intercom 10 memorizes in the memory unit 17 whether to execute the suppression mode (whether or not to execute) for each intercom main unit 20 for management. When the setting unit 161 accepts either the designated mode of execution or non-execution of the designated suppression mode from the intercom main unit 20 installed in the dedicated unit E2, the identification code of the dedicated unit E2 provided with the intercom main unit 20 is associated with the designated mode. The relationship is stored in the memory unit 17. Here, the identification code of the dedicated unit E2 is, for example, a room number.

The first removal unit 162 includes, for example, a plurality of echo cancellers. In this embodiment, the first removal unit 162 includes a first echo canceller 201 and a second echo canceller 202 . The first echo canceller 201 suppresses or removes the echo of the audio signal output from the first microphone 141 . The second echo canceller 202 suppresses or removes the echo of the audio signal output from the second microphone 142 . The first removal unit 162 outputs the suppressed or removed signal to the switching unit 163 .

The switching unit 163 switches the connection destination of the sound pickup unit 14 . Specifically, when the specified mode corresponding to the dedicated part E2 of the call object indicates that the suppression mode is executed, the switching part 163 connects the first microphone 141 and the second microphone 142 of the sound pickup part 14 to the suppression mode through the first removal part 162. Section 164 is connected.

The switching unit 163 connects the first microphone 141 to the second removing unit 165 through the first echo canceller 201 of the first removing unit 162 when the designated mode corresponding to the dedicated unit E2 of the calling party indicates that the suppression mode is not executed. The switching unit 163 disconnects the second microphone 142 from both the suppressing unit 164 and the second removing unit 165 . Specifically, the second echo canceller 202 is disconnected from both the suppression unit 164 and the second removal unit 165 .

The suppression unit 164 includes, for example, a beam forming circuit. The suppressing unit 164 performs suppressing processing when the specified mode corresponding to the dedicated unit E2 of the call destination indicates that the suppressing mode is executed. Specifically, the suppression unit 164 uses the echo-suppressed or removed signal picked up by the first microphone 141 (first sound signal) and the echo-suppressed or removed signal picked up by the second microphone 142 (second sound signal). , with respect to the output sound of the sound picked up from the front direction B1, the output sound for the sound picked up from the left direction B3 is suppressed. For example, the suppression part 164 weakens the intensity of the sound picked up from the left direction B3 relative to the intensity of the sound picked up from the front direction B1. The suppressing unit 164 outputs to the second removing unit 165 an audio signal including the sound picked up from the front direction B1 and the right direction B2 and the sound picked up from the left direction B3 with reduced signal strength.

The second removal unit 165 includes, for example, a noise suppressor. The second removal unit 165 suppresses or removes noise on the audio signal received from the first removal unit 162 .

The processing part 166 performs the processing related to a call, and performs the processing related to the call when it is in a state where a call can be made with the main unit 20 of the walkie-talkie.

When the processing unit 166 is in a state where the communication with the main unit 20 of the intercom is possible, the signal of the sound whose noise has been suppressed or removed by the second removal unit 165 is sent to the main unit 20 of the intercom via the communication unit 12 . The processing unit 166 outputs the audio signal received from the intercom main unit 20 (including the audio signal of the operator of the intercom main unit) to the output unit 15 when the communication with the intercom main unit 20 is possible.

When calling, the processing unit 166 sends the setting information of whether the suppression mode is set as the setting mode memorized by the memory unit 17 (the mode set at the time of setting) (whether the suppression mode is set) via the communication unit 12 to the corresponding intercom main unit of the call 20.

Memory section 17 is selected from ROM (Read Only Memory, read-only memory), RAM (Random Access Memory, random access memory), or EEPROM (Electrically Erasable Programmable Read Only Memory, electronically erasable programmable read-only memory) memory) and other components.

The memory part 17 has a setting table, and the setting table memorizes the setting mode set when the hall intercom 10 is set, and the specified mode set by each intercom main unit 20 (dedicated part E2) when setting the suppression mode as the setting mode (refer to Table 1).

[Table 1]

The setting table shown in Table 1 includes setting mode items and specifying mode items. The mode set during the setting of the hall intercom 10 is stored in the setting mode item. Store "ON" or "OFF" in the setting mode item. When the suppression mode is set as the setting mode, "ON" is stored in the setting mode item, and when the non-suppression mode is set as the setting mode, "OFF" is stored in the setting mode item. The designated mode designated by each dedicated part E2 is stored in the designated mode item. When the suppression mode is executed in the specified mode, "ON" is stored in the specified mode item, and "OFF" is stored in the specified mode item when the suppression mode is not executed. In Table 1, it is shown that the suppression mode is executed in the dedicated unit E2 with the room number 101, and the suppression mode is not executed in the dedicated unit E2 with the room number 102. Furthermore, if the suppression mode is set as the setting mode when the hall intercom 10 is installed, then for all the dedicated parts E2, "on" is set as the initial state in the designated mode item.

The walkie-talkie main unit 20 includes, for example, a microcomputer having a processor and a memory. And, the processor executes the program stored in the memory, whereby the microcomputer functions as the control unit 26 . Here, the program executed by the processor is pre-recorded in the memory of the microcomputer, but it may also be provided on a non-transitory recording medium such as a memory card, or provided through an electric communication line such as the Internet.

The first communication unit 21 is a communication interface for communicating with the control device 40 . The first communication unit 21 is connected to the hall intercom 10 via the control device 40 . For example, the first communication unit 21 receives an image transmitted from the hall intercom 10 . Furthermore, the first communication unit 21 is configured to enable bidirectional communication with the hall intercom 10 so that audio signals and control signals can be bidirectionally transmitted between the hall intercom 10 .

The second communication part 22 is a communication interface for communicating with the handset 30 of the walkie-talkie. The second communication unit 22 is electrically connected to the handset 30 via a two-wire transmission path including, for example, a twisted pair.

The operation part 23 accepts the operation of the resident in the dedicated part E2. When the first communication unit 21 receives a control signal (call signal) for calling a resident from the hall intercom 10 and performs a specific operation on the operation unit 23, it becomes possible to communicate between the intercom main unit 20 and the hall intercom 10. The status of the call. Here, the specific operation is, for example, a pressing operation. When the first communication unit 21 receives a call signal from the lobby intercom 10 or is able to communicate with the lobby intercom 10, when the door 51 installed in the common part is unlocked, the unlock signal is sent to the control device 40 .

Furthermore, when the second communication part 22 receives a control signal (call signal) for calling the resident from the intercom sub-unit 30 and performs a specific operation (such as a push operation) on the operation part 23, it becomes possible to communicate with the intercom main unit. 20 is in the state of communicating with the handset 30 of the walkie-talkie.

That is, the display unit 24 displays buttons and the like as a part of the operation unit 23 in addition to displaying images captured by the imaging unit 11 . The operation unit 23 accepts an instruction corresponding to a button displayed on the display unit 24 by pressing the button.

The display unit 24 displays different buttons depending on the setting mode set in the hall intercom 10 . When the suppression mode is set as the setting mode, the display unit 24 displays two buttons B10 and B11 (see FIG. 4A ) indicating whether to execute the suppression mode. Button B10 is a button that is pressed when indicating a situation to execute the suppression mode. The button B11 is a button that is pressed when indicating a situation where the suppression mode is not executed. In addition, the display unit 24 displays the button B10 and the button B11 in different colors according to the designation mode set at the current time. As shown in FIG. 4A , the specified mode set at the current time point represents the execution suppression mode. When the non-suppression mode is set as the setting mode, the display unit 24 does not display the two buttons B10 and B11 (see FIG. 4B ) indicating whether to execute the suppression mode.

Accordingly, when the suppression mode is set as the setting mode in the hall intercom 10, the resident can individually set whether to execute the suppression mode.

The communication unit 25 includes a speaker and a microphone, and is configured to be able to communicate with the lobby intercom 10 and the sub-intercom 30 .

When the control unit 26 receives a control signal (call signal) and an image captured by the camera unit 11 from the hall intercom 10 via the first communication unit 21, it outputs the sound data of the call sound to the speaker of the communication unit 25, and sends the received The image is output to the display unit 24 .

The walkie-talkie slave 30 includes a speaker and a microphone, and is configured to be able to communicate with the walkie-talkie main unit 20 .

(3) action Here, the operation of the intercom system 1 will be described using a specific example.

(3-1) Actions during a call First, the operation of the hall intercom 10 during a call will be described using the flowchart shown in FIG. 5 .

When a call is started between the hall intercom 10 and the intercom main unit 20, the sound pickup unit 14 collects the sound including the visitor's audio (step S1).

The first removal unit 162 performs echo cancellation processing on the audio signals received from the first microphone 141 and the second microphone 142 (step S2). Specifically, the first echo canceller 201 performs echo cancellation processing on the audio signal received from the first microphone 141 . The second echo canceller 202 performs echo cancellation processing on the audio signal received from the second microphone 142 .

The control part 16 judges whether the setting mode of the hall intercom 10 is a suppression mode (step S3). Specifically, the control unit 16 determines whether ON is stored in the setting mode item of the setting table stored in the memory unit 17 .

When the setting mode is the suppression mode ("Yes" in step S3), the suppression unit 164 performs suppression processing (step S4). Specifically, first, the switching unit 163 connects the first microphone 141 and the second microphone 142 of the sound pickup unit 14 to the suppressing unit 164 via the first removing unit 162 . The suppression unit 164 uses the first sound signal of the sound picked up by the first microphone 141 and subjected to the echo cancellation process and the second sound signal of the sound picked up by the second microphone 142 and subjected to the echo cancellation process. The output sound of the picked up sound suppresses the output sound for the sound picked up from the left direction B3. The suppression unit 164 outputs the suppressed audio signal to the second removal unit 165 .

When the setting mode is the non-suppression mode (“No” in step S3 ), the signal of the sound picked up by the first microphone 141 is output to the second removal unit 165 via the first removal unit 162 .

The second removal unit 165 performs noise cancellation processing on the audio signal on which the echo cancellation processing has been performed (step S5).

The processing unit 166 performs a transmission process of transmitting the echo-canceled audio signal to the intercom main unit 20 via the communication unit 12 (step S6). At this time, the processing unit 166 outputs information related to the setting mode set in the hall intercom 10 (whether or not the suppression mode is set) to the intercom main unit 20 via the communication unit 12 . Moreover, the processing unit 166 sends the image captured by the camera unit 11 together with the audio signal to the intercom main unit 20 during the call.

The control unit 16 judges whether or not the call has ended (step S7). When it is judged that the call has not ended ("No" in step S7), the process returns to step S1. When it is judged that the call has ended ("Yes" in step S7), the process ends.

As explained above, when the suppression mode is set, the picked up sound is suppressed, and when the suppression mode is not set (when the non-suppression mode is set), the picked up sound is not suppressed. Implement suppression processing. Specifically, when the suppression mode is set, the first sound signal of the sound picked up by the first microphone 141 and the second sound signal of the sound picked up by the second microphone 142 are respectively input to the suppression unit 164 (see FIG. 2A). Using the first sound signal and the second sound signal, the sound signal including the sound input from the front direction B1 and the right direction B2 and the sound after the sound input from the left direction B3 is suppressed passes through the first removal unit 162, the second 2 The removal unit 165 and the processing unit 166 are sent to the intercom main unit 20. On the other hand, when the suppression mode is not set, the audio signal of the sound picked up by the first microphone 141 is input to the first removal unit 162 without passing through the suppression unit 164 (see FIG. 2B ). Thereafter, the audio signal input to the first removal unit 162 is sent to the intercom main unit 20 via the second removal unit 165 and the processing unit 166 .

(3-2) Operation of changing the specified mode Here, the operation when the button B11 displayed on the walkie-talkie main unit 20 is pressed during a call will be described using the sequence diagram of FIG. 6 .

The processing unit 166 of the hall intercom 10 performs the output processing described in step S6, and outputs the sound signal, whether the suppression mode is set, and the image captured by the camera unit 11 to the intercom main unit 20 via the communication unit 12 (steps S10, S11) .

The walkie-talkie host 20 performs call processing (step S12). Specifically, the intercom main unit 20 outputs the sound (including the visitor's audio) from the speaker of the communication part 25 based on the sound signal received from the hall intercom 10 , and displays the image captured by the camera part 11 on the display part 24 . At this time, in addition to the image captured by the imaging unit 11, the content displayed on the display unit 24 also displays at least buttons B10 and B11 as shown in FIG. 3A. Buttons B10 and B11 are color-coded in such a way that the occupants can recognize the specified mode set at the current time point to indicate the execution inhibition mode.

When the button B11 is pressed in the state where the buttons B10 and B11 are displayed, the setting information for setting the non-execution suppression mode is received, and the setting information is sent to the hall intercom 10 (steps S13 and S14).

When receiving the setting information, the setting unit 161 of the hall intercom 10 sets the designated mode based on the setting information (step S15). In this case, the setting unit 161 sets a designation mode indicating that the suppression mode is not executed in the setting table.

When the processing unit 166 of the hall intercom 10 is input with audio including the visitor’s audio, it performs output processing again, and outputs the audio signal, whether the suppression mode is set, and the image captured by the camera unit 11 to the intercom main unit through the communication unit 12 20 (steps S16, S17).

The walkie-talkie host 20 performs call processing (step S18). In this case, the buttons B10 and B11 are color-coded in such a way that the resident can recognize that the specified mode set at the current time indicates that the suppression mode is not executed.

In this embodiment, if the specified mode is changed, the content of the changed specified mode is valid until the next setting information is accepted.
