Description

This invention relates to an intercom system for apartment buildings that double-checks visitors by providing automatic doors at the main entrance and on each residential floor, for example.

To improve security, some apartment buildings have installed automatic doors on each residential floor in the living area in addition to an automatic door at the main entrance. When two automatic doors are installed in this way, visitors must first call a resident from the entrance collective entrance machine installed at the main entrance to have the automatic door at the main entrance opened, and then call a resident again from the floor collective entrance machine installed on the residential floor they are visiting to have the automatic door on that floor opened.

To ease the burden on residents, an apartment complex intercom system has been devised that issues a one-time password at the entrance collective entrance machine and has the visitor enter this one-time password at a floor collective entrance machine installed on the residential floor of the person they are visiting, allowing the visitor to open the automatic doors on each residential floor (for example, Patent Document 1).

However, with the above-mentioned apartment complex intercom system, if, for example, a delivery person needs to visit multiple rooms, the delivery person must have multiple one-time passwords issued for each floor of the rooms at the entrance collective entrance machine, memorize these, and then enter the one-time password corresponding to each floor of the rooms to be visited into the floor collective entrance machine, which still poses issues in terms of usability. Also, depending on the order of the rooms to be visited, there may be a delay between answering the call from the entrance collective entrance machine and the visitor actually visiting the room, which can be uncomfortable for residents.

The present invention has been made in consideration of the above problems, and aims to provide an apartment complex intercom system that is easier to use than conventional intercom systems for apartment complexes that have double automatic doors.

In order to achieve the above object, the present invention provides an apartment building intercom system comprising an entrance collective entrance unit installed at the main entrance of an apartment building, a floor collective entrance unit installed at the entrance of each living room floor, an entrance sub-unit installed at the entrance of each living room, a room master unit installed in each living room, a first automatic door installed at the main entrance and passed through when proceeding to the living area where the living rooms are located, a second automatic door installed at the entrance of the living room floor and passed through when proceeding to the living room side, and a controller that controls communication between the entrance collective entrance unit, the floor collective entrance unit, the entrance sub-unit, the living room master unit, the first automatic door, and the second automatic door. The entrance collective entrance machine is equipped with a first camera, and the floor collective entrance machine is equipped with a second camera , while the control machine is provided with a person identification unit which identifies a person appearing in both images taken by the first camera and the second camera, and identifies a person appearing in both images taken by the second camera of the first floor collective entrance machine, which is a floor collective entrance machine installed on a specific room floor, and the second camera of the second floor collective entrance machine, which is a floor collective entrance machine installed on a room floor other than the specific room floor , and a person identification unit which identifies a person appearing in both images taken by the first camera and the second camera. and a visitor information registration unit that stores an image captured by the first camera, and when a visitor operates the entrance collective entrance machine and the first automatic door is unlocked by a resident who has been called by the operation, the person identification unit associates a first identification image of the visitor captured by the first camera with a room number related to the called-out resident's room and stores it in the visitor information registration unit, and identifies whether or not the person is a visitor based on the person captured by the second camera of the floor collective entrance machine installed on the resident's floor corresponding to the called-out resident's room and the first identification image, and when the person identification unit identifies the person as a visitor, the control machine unlocks the second automatic door on the resident's floor corresponding to the called-out resident's room. On the other hand, when a visitor operates the first floor collective entrance machine and the visitor is authenticated by a resident who is called by this operation, the person identification unit links a second identification image of the visitor taken by the second camera of the first floor collective entrance machine to the room number related to the called destination room and stores it in the visitor information registration unit, and identifies whether the person is a visitor or not based on the person and the second identification image taken by the second camera of the second floor collective entrance machine installed on the room floor corresponding to the called destination room, and when the person identification unit identifies the person as a visitor, the control machine unlocks the second automatic door on the room floor corresponding to the called destination room.

According to the present invention, a first camera is provided at the entrance collective entrance machine, and a second camera is provided at the floor collective entrance machine, and the control machine is provided with a person identification unit that identifies a person appearing in both images taken by the first camera and the second camera, and a visitor information registration unit that stores the image taken by the first camera. The person identification unit is a first access point that is used by a visitor to proceed from the main entrance to the living area where the rooms are located, when the entrance collective entrance machine is operated by a visitor and a resident is called by the operation. When the door is unlocked, a first identification image showing the visitor captured by the first camera is linked to the room number of the called room and stored in the visitor information registration section, and the control machine identifies whether the person is a visitor or not from the person captured by the second camera of the floor collective entrance machine installed on the room floor corresponding to the called room and the first identification image, and when the person identification section identifies the person as a visitor, the control machine unlocks the second automatic door for proceeding from the entrance of the room floor corresponding to the called room to the room side. Therefore, the visitor can proceed to the room side through the second automatic door without operating the floor collective entrance machine, making it possible to provide an easy-to-use apartment building intercom system.
The visitor information registration unit is adapted to store images captured by the second camera, and the person identification unit is adapted to identify persons appearing in both images captured by the second camera of a first floor collective entrance machine installed on a specified living room floor and an image captured by the second camera of a second floor collective entrance machine installed on a living room floor other than the specified living room floor. When a visitor operates the first floor collective entrance machine and the visitor is authenticated by a resident who has been called by the operation, A second identification image of the visitor captured by the second camera of the first floor collective entrance machine is stored in the visitor information registration section in association with the room number of the called room, and the person captured by the second camera of the second floor collective entrance machine installed on the room floor corresponding to the called room is used to identify whether the person is a visitor or not, and when the person identification section identifies the person as a visitor, the control machine unlocks the second automatic door for proceeding from the entrance of the room floor corresponding to the called room to the room side. Therefore, when visiting multiple rooms on different room floors, the visitor does not need to return to the entrance collective entrance machine or memorize and input multiple passwords, making the apartment house intercom system extremely easy to use, and since the visitor visits the room in a relatively short time after being called by the visitor, the apartment house intercom system does not cause the visitor to feel uncomfortable as in the past.

The entrance collective hall unit 1 is equipped with a camera 11 for capturing images of visitors, a microphone 12 and a speaker 13 for communication between the visitor and the resident, an operation unit 14 where the visitor inputs the room number to be called (the room number of the person to be visited), a display unit 15 that displays the operation content, a first collective hall unit control unit 16 that communicates with the control unit (not shown) of the first automatic door 6a to control the opening and closing of the first automatic door 6a and also controls the operation of the entrance collective hall unit 1 itself, and a first collective hall unit communication IF 17 for communicating with the intercom control unit 5.

The floor collective entrance unit 2 is configured in a similar manner to the entrance collective entrance unit 1, and includes a camera 21, a microphone 22 and a speaker 23, an operation unit 24, a display unit 25, a second collective entrance unit control unit 26 that communicates with the control unit (not shown) of the second automatic door 6b to control the opening and closing of the second automatic door 6b and also controls the operation of the floor collective entrance unit 2 itself, and a second collective entrance unit communication IF 27 that communicates with the intercom control unit 5.

The entrance sub-unit 3 is equipped with a camera 31 for capturing an image of a visitor in front of the living room, a call button 32 that allows the visitor to call the resident, a microphone 33 and a speaker 34 for talking when calling, a sub-unit control unit 35 for controlling the entrance sub-unit 3 itself, and a sub-unit communication IF 36 for communicating with the living room master unit 4.

The room master unit 4 is equipped with a call button 41 for answering calls from the entrance collective hall unit 1 and the hallway sub-unit 3 that is paired with the room master unit 4, a microphone 42 and speaker 43 for talking when answering, an operation unit 44 for various operations, a display unit 45 for displaying various information in addition to images captured by the camera 11 of the entrance collective hall unit 1 and the camera 21 of the floor collective hall unit 2, a master unit control unit 46 for controlling the room master unit 4 itself, a master unit first communication IF 48 for communicating with the intercom control unit 5, and a master unit second communication IF 49 for communicating with the hallway sub-unit 3 that is paired with it.

The intercom control unit 5 comprises a visitor information registration unit 52 for linking a first image (first identification image) of the visitor extracted from the video captured by the camera 11 of the entrance collective entrance unit 1 and a second image (second identification image) of the visitor extracted from the video captured by the camera 21 of the floor collective entrance unit 2 to each room number and storing them, a room floor information storage unit 53 for storing the relationship between the room number and the room floor, a control unit control unit 54 for controlling the operation of the intercom control unit 5 itself, and a control unit communication IF 55 for communicating with the entrance collective entrance unit 1, the floor collective entrance units 2, 2..., the surveillance camera 9, and the room master units 4, 4... The control device control unit 54 also includes a person identification unit 54a for identifying whether the visitor who called the resident from the entrance collective entrance unit 1 and the person photographed by the floor collective entrance unit 2 are the same person, as described below, and whether the person who called the resident from the first floor collective entrance unit 2 and the person photographed by the second floor collective entrance unit 2 are the same person.

The operation of the above-described apartment house intercom system and the control related to person identification are as follows.
When a visitor operates the entrance assembly hall unit 1 and inputs the room number of the visitor to make a call, a call signal is sent to the room master unit 4 installed in the room corresponding to the input room number under the control of the intercom control unit 5. The room master unit 4 then sounds a call tone upon receiving the call signal to notify the resident that a visitor has arrived. In addition, in response to the visitor's operation of the entrance assembly hall unit 1, the entrance assembly hall unit 1 starts capturing images with the camera 11, and together with the transmission of the call signal as described above, the image captured by the camera 11 is sent to the room master unit 4 via the intercom control unit 5 and is displayed on the display unit 45 of the room master unit 4.

On the other hand, when a resident who recognizes the call from the ring tone responds with the room master unit 4, a communication path is established between the room master unit 4 and the entrance collective hall unit 1, enabling a conversation between the visitor and the resident. When the resident recognizes the visitor through this conversation and performs a specified unlocking operation with the operation unit 44, an unlocking signal is sent to the first automatic door 6a via the intercom control unit 5 and the entrance collective hall unit 1, and the first automatic door 6a is unlocked and then opened.

In response to the resident's unlocking of the first automatic door 6a, the person identification unit 54a of the control unit 54 in the intercom control unit 5 extracts an image capable of authenticating the visitor from the video captured by the camera 11 of the entrance collective entrance unit 1 as the first image, links it to the input room number of the visitor, and stores it in the visitor information registration unit 52. In response to the resident's unlocking of the first automatic door 6a, under the control of the intercom control unit 5, the floor collective entrance unit 2 installed at the entrance of the room floor corresponding to the room number starts up the camera 21 and waits for the visitor to arrive. Then, when the visitor approaches the floor collective entrance unit 2, the visitor is captured by the camera 21, which has already started capturing images, and the image is sent to the intercom control unit 5.

In addition, the person identification unit 54a of the intercom control device 5 extracts an image capable of authenticating a person captured by the camera 21 of the floor collective entrance device 2, compares the image with the first image linked to the corresponding room number, and performs an identification determination as to whether or not the person captured by the camera 21 of the floor collective entrance device 2 is the visitor. If the person captured by the camera 21 of the floor collective entrance device 2 is identified as a visitor, an unlocking signal is sent from the intercom control device 5 to the second automatic door 6b via the floor collective entrance device 2, and the second automatic door 6b is unlocked and opened. On the other hand, if the person captured by the camera 21 of the floor collective entrance device 2 cannot be identified as a visitor, an unlocking signal is not sent from the intercom control device 5 to the second automatic door 6b, and the second automatic door 6b is not opened. If the person captured by the camera 21 of the floor collective entrance device 2 cannot be identified as a visitor, a message such as "This is not the floor you are visiting. Have you come to the wrong floor?" may be sounded from the speaker 23 of the floor collective entrance device 2.

Furthermore, when the call button 32 of the entrance slave unit 3 is operated by a visitor who has arrived in front of the living room, the entrance slave unit 3 starts capturing images with the camera 31. The image captured by the camera 31 (image of the visitor who operated the call button 32) is sent to the intercom control unit 5 with the room number attached via the room master unit 4. Furthermore, the person identification unit 54a of the intercom control unit 5 extracts an image that can identify the person captured by the camera 31 of the entrance slave unit 3, compares the image with the first image linked to the corresponding room number, and makes an identification judgment as to whether the person captured by the camera 31 of the entrance slave unit 3 is the visitor. Then, when the person captured by the camera 31 of the entrance slave unit 3 is identified as a visitor, the intercom control unit 5 transmits an authorization signal to the room master unit 4, and the room master unit 4 issues a call sound upon receiving the authorization signal, thereby notifying the resident that the visitor has arrived in front of the living room.

On the other hand, if the person captured by the camera 31 of the entrance sub-unit 3 cannot be identified as a visitor, the intercom control unit 5 does not send an authorization signal to the room main unit 4, and the room main unit 4 does not sound a ringtone. If the person captured by the camera 31 of the entrance sub-unit 3 cannot be identified as a visitor, the intercom control unit 5 may send a non-authorization signal to the room main unit 4, and upon receiving the non-authorization signal, the room main unit 4 may sound a message from the speaker 34 of the entrance sub-unit 3, such as "This is not the person you are visiting. Have you come to the wrong place?"

Furthermore, if a visitor visits a room (second room) on another resident floor after visiting the first resident room, the visitor is made to operate the floor collective entrance unit 2 (first floor collective entrance unit 2) at the entrance of a resident floor other than the resident floor on which the second resident room is located (usually this would be the resident floor on which the first resident room is located). That is, the visitor is made to input the room number of the second resident room into the first floor collective entrance unit 2 to make the call, just as when calling the first resident room from the entrance collective entrance unit 1. Then, under the control of the intercom control unit 5, a call signal is sent to the room master unit 4 installed in the second resident room, and upon receiving the call signal, the room master unit 4 sounds a call tone to notify the resident that a visitor has arrived. In addition, when a visitor operates the first floor collective entrance unit 2, the first floor collective entrance unit 2 starts capturing images using the camera 21, and along with sending the call signal as described above, the image captured by the camera 21 is sent via the intercom control unit 5 to the room master unit 4 of the second room, and is displayed on the display unit 45 of the room master unit 4.

On the other hand, when the resident of the second room recognizes the call by the ring tone and responds with the room master unit 4, a call path is formed between the room master unit 4 and the first floor collective entrance unit 2, enabling a call between the visitor and the resident. When the resident recognizes the visitor through this call and performs a predetermined authentication operation with the operation unit 44, an authentication signal is sent to the intercom control unit 5. In addition, in the intercom control unit 5, upon receiving the authentication signal, the person identification unit 54a of the control unit control unit 54 extracts an image that can authenticate the visitor from the video captured by the camera 21 of the first floor collective entrance unit 2 as the second image, links it to the room number of the second room, and stores it in the visitor information registration unit 52. Furthermore, upon receiving the authentication signal, under the control of the intercom control unit 5, the floor collective entrance unit 2 (second floor collective entrance unit 2) installed at the entrance of the room floor where the second room is located starts up the camera 21 and waits for the visitor to arrive. When a visitor approaches the second floor collective entrance unit 2, the visitor is captured on the camera 21, and the image is transmitted to the intercom control unit 5.

The person identification unit 54a of the intercom control device 5 extracts an image capable of authenticating a person captured by the camera 21 of the second floor collective entrance device 2, compares the image with the second image linked to the corresponding room number, and performs an identification judgment as to whether the person captured by the camera 21 of the second floor collective entrance device 2 is the visitor. If the person captured by the camera 21 of the second floor collective entrance device 2 is identified as a visitor, an unlocking signal is sent from the intercom control device 5 to the second automatic door 6b via the second floor collective entrance device 2, and the second automatic door 6b is unlocked and opened. On the other hand, if the person captured by the camera 21 of the second floor collective entrance device 2 cannot be identified as a visitor, an unlocking signal is not sent from the intercom control device 5 to the second automatic door 6b, and the second automatic door 6b is not opened.

Furthermore, when the call button 32 of the front door sub-unit 3 is operated by a visitor who has arrived in front of the second room, the front door sub-unit 3 begins capturing images using the camera 31. The image captured by the camera 31 (image of the visitor who operated the call button 32) is sent to the intercom control unit 5 via the room master unit 4 with the room number of the second room attached. Furthermore, the person identification unit 54a of the intercom control unit 5 extracts an image that can authenticate the person captured by the camera 31 of the front door sub-unit 3, compares the image with the second image linked to the corresponding room number, and makes an identification judgment as to whether the person captured by the camera 31 of the front door sub-unit 3 is the visitor. If the person captured by the camera 31 of the entrance sub-unit 3 is identified as a visitor, the intercom control unit 5 transmits a permission signal to the room master unit 4 of the second room, which, upon receiving the permission signal, sounds a ringing sound to notify the resident that the visitor has arrived in front of the room. On the other hand, if the person captured by the camera 31 of the entrance sub-unit 3 cannot be identified as a visitor, the intercom control unit 5 does not transmit a permission signal to the room master unit 4 of the second room, and the room master unit 4 of the second room does not sound a ringing sound.

When a visitor visits multiple rooms on the same floor, the entrance collective entrance machine 1 or the first floor collective entrance machine 2 can be used to call the visitor to all the rooms on the same floor, and the first and second images of the visitor can be stored in the visitor information registration unit 52 linked to the multiple room numbers. In addition, since the surveillance camera 9 is constantly capturing images for the purpose of improving security, such as preventing intrusions by suspicious people, the surveillance camera 9 can be the camera 11 of the entrance collective entrance machine 1, and an image that can authenticate the visitor can be extracted as the first image from the video captured by the surveillance camera 9, and the first image can be linked to the room number and stored in the visitor information registration unit 52.

Here, a specific description will be given of the actual operation of the apartment complex intercom system when a visitor visits Room 304 on the third floor and Room 501 on the fifth floor.
First, when a visitor inputs the room number of the first room, "304," into the entrance collective hall unit 1, the room master unit 4 installed in the first room, room 304, is called. Then, when the resident of room 304 performs the unlocking operation, the first automatic door 6a is opened, and the visitor can proceed to the living area. At this time, the intercom control unit 5 stores the first image of the visitor based on the video captured by the camera 11 of the entrance collective hall unit 1.

Next, when a visitor who has arrived on the third floor approaches the first floor collective entrance unit 2 installed at the entrance on the third floor, the intercom control unit 5 identifies the person approaching the first floor collective entrance unit 2 from the video captured by the camera 21 of the first floor collective entrance unit 2 and the first image, and if the person is identified as a visitor, the second automatic door 6b installed at the entrance on the third floor opens without the visitor having to operate the first floor collective entrance unit 2, and the visitor can proceed to the front of the room 304. Then, when the visitor operates the call button 32 of the entrance sub-unit 3 of room 304, the intercom control unit 5 identifies the person who called the entrance sub-unit 3 from the video captured by the camera 31 of the entrance sub-unit 3 and the first image, and if the person is identified as a visitor, a call tone is issued from the room master unit 4 of room 304.

The visitor then returns to the third floor entrance and enters the room number of the second room, "501", into the first floor collective entrance unit 2. This calls the room master unit 4 installed in the second room, room 501. When the resident of room 501 performs the authentication operation, a second image of the visitor based on the video captured by the camera 21 of the first floor collective entrance unit 2 is stored in the intercom control unit 5. In addition, when a visitor who has arrived on the fifth floor approaches the second floor collective entrance unit 2 installed at the entrance of the fifth floor, the intercom control unit 5 identifies the person approaching the second floor collective entrance unit 2 from the video captured by the camera 21 of the second floor collective entrance unit 2 and the second image, and if the person is identified as a visitor, the second automatic door 6b installed at the entrance of the fifth floor is opened without the visitor operating the second floor collective entrance unit 2, and the visitor can proceed to the front of the room 501. Then, when the visitor operates the call button 32 of the entrance sub-unit 3 of room 501, the intercom control unit 5 identifies the person who called the entrance sub-unit 3 from the video captured by the camera 31 of the entrance sub-unit 3 and the second image, and if the person is identified as a visitor, a call tone is notified from the room master unit 4 of room 501.

According to the apartment complex intercom system having the above-mentioned configuration, the entrance collective entrance unit 1 is provided with a camera 11, and the floor collective entrance unit 2 is provided with a camera 21. The intercom control unit 5 is equipped with a person identification unit 54a that identifies people appearing in both images taken by the camera 11 and the image taken by the camera 21, and a visitor information registration unit 52 that stores the image taken by the camera 11. The person identification unit 54a is used when a visitor operates the entrance collective entrance unit 1 and a resident who is called by the operation operates the entrance collective entrance unit 1 to enter the location of a room from the main entrance. When the first automatic door 6a for entering the residential area is unlocked, the first image of the visitor captured by the camera 11 is linked to the room number of the called room and stored in the visitor information registration unit 52, and the person is identified as a visitor from the first image and the person captured by the camera 21 of the floor collective entrance unit 2 installed on the room floor corresponding to the called room. If the person is identified as a visitor by the person identification unit 54a, the intercom control unit 5 unlocks the second automatic door 6b for entering the room side from the entrance of the room floor corresponding to the called room. Therefore, the visitor can enter the room side through the second automatic door 6b without operating the floor collective entrance unit 2, making it an easy-to-use apartment building intercom system.

In addition, the visitor information registration unit 52 is adapted to store images captured by the camera 21 of the floor collective entrance machine 2, and the person identification unit 54a is adapted to identify a person appearing in both images captured by the camera 21 of the first floor collective entrance machine 2 installed on a specific residential floor and the image captured by the camera 21 of the second floor collective entrance machine 2 installed on a residential floor other than the specific residential floor. When a visitor operates the first floor collective entrance machine 2, the visitor is authenticated by a resident who is called by the operation. When the call is received, the second image of the visitor captured by the camera 21 of the first floor collective entrance unit 2 is stored in the visitor information registration unit 52 in association with the room number of the called room, and the person captured by the camera 21 of the second floor collective entrance unit 2 installed on the room floor corresponding to the called room is used to identify whether the person is a visitor or not, and when the person identification unit 54a identifies the person as a visitor, the intercom control unit 5 unlocks the second automatic door 6b for proceeding from the entrance of the room floor corresponding to the called room to the room side. Therefore, when visiting multiple rooms on different room floors, the visitor does not need to return to the entrance collective entrance unit 1 or memorize and enter multiple passwords, making the apartment house intercom system extremely easy to use, and since the visitor visits the room in a relatively short time after being called by the visitor, the apartment house intercom system does not cause the visitor to feel uncomfortable as in the past.

The apartment complex intercom system according to the present invention can be modified as needed without departing from the spirit of the present invention, not only in terms of the overall configuration of the apartment complex intercom system and the overall configuration of each device, but also in terms of the configuration related to person identification, etc.

For example, in the above embodiment, imaging by the camera 31 is started in response to the operation of the call button 32 of the front door sub-unit 3, but in response to the unlocking of the second automatic door 6b, a second unlocking signal is sent from the intercom controller 5 to the room master unit 4, and in response to receiving the second unlocking signal, the room master unit 4 starts the camera 31 of the paired front door sub-unit 3, and identifies whether or not the person captured on the camera 31 is a visitor before the visitor operates the call button 32 of the front door sub-unit 3. By adopting such a configuration, it is possible to achieve the effect of quickly making a call when a visitor operates the front door sub-unit to make a call.

It is also possible to install surveillance cameras at the entrances of each residential floor and use these surveillance cameras as cameras for the floor's collective entrance system.
Furthermore, in the above embodiment, the room parent unit is configured to unlock the room in response to a call from the entrance collective entrance unit, and the room parent unit is configured to authenticate the room in response to a call from the floor collective entrance unit (in other words, these are separate operations), but it is also possible to configure the room parent unit to respond to calls from either collective entrance unit with the same authentication operation.
