Description

[Technical Field]

[0001] The present invention relates to an intercom system for apartment buildings, and in particular to an intercom system for apartment buildings that does not require major modifications to existing intercom systems, and that enables calling residents and unlocking operations without directly touching input buttons, etc., by connecting a non-contact input device. [Background technology]

[0002] In recent years, apartment complex intercom systems have been adopted in which a collective entrance machine is installed at the entrance of an apartment complex, and visitors can call a resident by operating buttons such as a numeric keypad located on the operation panel of the collective entrance machine to specify a room number, and which also have the function of unlocking the door when a resident returns home and enters the living area from the entrance (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent Publication No. 2021-61544 Summary of the Invention [Problem to be solved by the invention]

[0004] Conventional apartment complex intercom systems are typically operated using mechanical buttons or touch panels. Because both require direct contact with the buttons or screen, operating them requires direct contact with the buttons or screen. For devices operated by an unspecified number of people, touching buttons that have been touched by others can raise hygiene concerns. These hygiene concerns have become particularly acute in light of the recent outbreak of viral infections. For example, in apartment complexes with large entrance halls where many people, including visitors and returning residents, enter and exit, caretakers must disinfect the operating panel with alcohol or other disinfectants every few hours, placing a significant burden on caretakers who also have other responsibilities. While some systems encourage visitors to disinfect their hands before operating the intercom system by keeping a container of disinfectant alcohol near the entrance hall, particularly during times when many people enter and exit the building in a short period of time, the supply of disinfectant can be in short supply, making hygiene concerns difficult to fully address, and maintaining this system is also a significant burden.

[0005] In response to this situation, contactless input devices have been proposed that allow data to be entered without directly touching the input operation unit. For apartment complex intercom systems, the above problems could be solved by incorporating such contactless input devices into the entrance hall unit, thereby developing a new entrance hall unit that can be operated without touching any buttons. However, developing and manufacturing a new entrance hall unit incorporating such contactless input devices requires significant costs, and installing such a unit in an apartment complex involves discarding the existing entrance hall unit, which is still fully operational, and installing a new one, which is wasteful. Furthermore, installing a new entrance hall unit requires extensive construction work, which also requires significant costs.

[0006] In view of these problems, the present invention aims to provide an apartment building intercom system that enables contactless input operations that do not require direct contact with the device, by making only the minimum necessary modifications to the existing intercom system. [Means for solving the problem]

[0007] In order to solve the above-mentioned problems, the apartment building intercom system of the present invention is an apartment building intercom system having a collective entrance unit which has the calling / talking function and door unlocking function of a room master unit installed in a room, and a non-contact input device which is connected to the collective entrance unit in a state where data can be sent and received between them and which allows data to be input without directly touching the input buttons, wherein the collective entrance unit has a receiving control unit for executing predetermined control processing based on data received from the non-contact input device, and the non-contact input device has a display unit which displays an input screen corresponding to each of a plurality of operation modes, a detection unit which detects the operation position by a detectable object on the input screen of the display unit, and a judgment unit which determines the operation content corresponding to the operation position detected by the detection unit, and the judgment unit generates command data by adding a parameter indicating the operation mode when the operation was performed to the data of the determined operation content and sends it to the collective entrance unit, and the receiving control unit executes the predetermined control processing based on the command data received from the non-contact input device. With this configuration, while using most of the existing collective entrance machine as is, the contactless input device can be connected and operated by adding a receiving control unit to the collective entrance machine that outputs the output data of the contactless input device in a format that corresponds to the processing format of the calculation processing unit of the collective entrance machine.This means that there is no need for large-scale renovation work, and with only minimal renovation, the existing collective entrance machine can be used as is and operation by contactless input can be enabled.

[0008] In another embodiment of the apartment building intercom system of the present invention, the non-contact input device has a unique ID, the command data sent and received between the collective entrance unit and the non-contact input device includes the ID of the non-contact input device, the collective entrance unit has a memory unit for storing the IDs of communication partners authorized to connect, and the reception control unit of the collective entrance unit can be configured to identify whether the ID included in the received command data is the ID of the communication partner stored in the memory unit. With this configuration, it is possible to identify whether the non-contact input device connected to the collective entrance unit is an individual non-contact input device authorized to connect before performing control processing, thereby preventing hijacking operations by sending command data from input devices that are not authorized to connect, and improving safety for operations that require high security, such as unlocking.

[0009] In another embodiment of the apartment building intercom system of the present invention, the non-contact input device may be configured to include a spatial projection device that projects the contents of the input screen of the display unit into space as a spatially projected image. With this configuration, input operations can be performed using the spatial image projected into space by the non-contact input device. This prevents the operator from misjudging the distance and touching the physical operation unit, as compared to a non-contact input device that detects the approach of a finger to a physical operation unit, thereby ensuring greater hygiene and safety. [Effects of the Invention]

[0010] According to the present invention, a non-contact input device can be incorporated into an existing intercom system without incurring significant costs, making it possible to operate the intercom without directly touching the operation screen while still using the existing intercom system, thereby improving hygiene as a measure against infectious diseases without requiring major renovation work. [Brief explanation of the drawings]

[0011] [Figure 1] 1 is a block diagram showing an example of an apartment building intercom system according to an embodiment of the present invention; DETAILED DESCRIPTION OF THE INVENTION

[0012] An embodiment of the present invention will be described in detail below with reference to the drawings. Fig. 1 is a block diagram showing an example of an apartment building intercom system according to the present invention, including a collective entrance unit 1 for visitors to perform operations such as calling residents, a non-contact input device 2 that can be used as an operating unit for the collective entrance unit without directly touching the input buttons, a room master unit 3 for responding to calls from the collective entrance unit 1, a control unit 4 that controls communication between devices such as the collective entrance unit 1 and the room master unit 3, and an automatic door 5 installed between the entrance to the apartment building and the living area. The automatic door is equipped with an electric lock (not shown) that allows only limited individuals to enter the living area. While Fig. 1 shows a case in which the automatic door 5 is connected to the control unit 4, the automatic door 5 may also be configured to be connected to the collective entrance unit 1.

[0013] The collective entrance unit 1 is connected to the non-contact input device 2 via transmission line L1, which is further connected to the control unit 4 via transmission line L2. The room master unit 3 is connected to the control unit 4 via the master unit trunk line L3. The electric lock (not shown) of the automatic door 5 is also connected to the control unit 4 via a transmission line. Some existing collective entrance units are permanently equipped with a LAN port terminal for connecting a maintenance computer or the like. Since this LAN port is only used during maintenance, the collective entrance unit 1 and the non-contact input device 2 can be connected via a LAN cable using this LAN port, eliminating the need to install a new connection terminal. By connecting a hub to the LAN cable connection, the maintenance terminal can be maintained as before. A standard LAN cable can be used for the connection; for example, a CAT5e cable is preferable.

[0014] As shown in Figure 1, the collective entrance machine 1 has an operation unit 11 that allows visitors to select the apartment they wish to visit and call the resident, a call unit 12 equipped with a microphone and speaker (not shown), a display unit 13 that displays the entered apartment number information and messages for visitors and those returning home, a camera 14 that takes pictures of visitors, a human presence sensor 15 that detects the approach of a visitor and lights up the screen of the display unit, a collective entrance machine CPU 16 that controls the collective entrance machine 1, a memory unit 17 that stores an identification ID for identifying the non-contact input device 2 connected to the collective entrance machine 1, a reception control unit 18 that analyzes command data sent from the non-contact input device 2 and passes the corresponding control command for the collective entrance machine 1 to the collective entrance machine CPU 16, and a collective entrance machine I / F 19 that communicates with the non-contact input device 2 and the control machine 4.

[0015] The non-contact input device 2 has a display unit 21 on which input buttons and an input screen for messages to visitors, etc. are projected, and a detection unit 22 that detects which position on the screen projected on the display unit 21 the visitor has operated. This allows the visitor to operate the device in the same way as with normal contact-type buttons without directly touching the input button by detecting which button displayed on the screen the visitor has indicated his / her intention to operate. The non-contact input device 2 also has a memory unit 23 that stores a unique identification ID that identifies itself, a determination unit 24 that controls the non-contact input device 2 and generates command data to be sent to the collective entrance device 1 based on the operation content detected by the detection unit 22, and an input / output device I / F 25 that communicates with the collective entrance device 1.

[0016] The non-contact input device 2 of the present invention is not particularly limited, and any type can be used as long as it can sense an operator's movements in the air and activate a predetermined function. Representative types of non-contact input devices include the following. For example, representative display types include a type that uses a physical display screen (such as a liquid crystal panel or organic electroluminescence (EL) panel) and performs hover input (gesture input) while a finger is held in the air, for example, 30 to 50 mm away from the display screen, and a so-called air display type in which the physical display screen is hidden from the operator and the contents of the display screen are projected into space as a spatially projected image. Sensor types include those that measure position and movement by shining infrared or laser light on a finger or wad and measuring the reflected light, those that analyze position and movement from images captured by a camera, and those that measure position and movement by detecting changes in electrostatic capacitance between the operating finger or wad and a sensor located on the panel. Various non-contact input devices have been proposed that combine these displays and sensors.

[0017] While the electrostatic capacitance type described above is a typical example of a hover input type, there is also a known system in which a holographic film containing an image is placed on the display of an information terminal and illuminated with light from a point light source such as an LED, causing the image to appear floating in space. This system uses one of the three-dimensional distance sensors described above to measure position and movement. A typical example of an aerial display system is one that uses retroreflective materials to project an image in space. This type of display system uses an optical system consisting of a light source (display), retroreflective materials, and beam splitters to re-image the light displayed on the display in the air, thereby creating an image floating in space. The principle is that light from the display first reflects normally off the beam splitter and travels to the retroreflective material. The light then retroreflects back in the same direction as it entered the beam splitter, traveling again to the beam splitter. The light that passes through the beam splitter converges and then diffuses again, projecting an image in space. In an aerial display, all of these components are contained within the device's housing, so the operator is unaware of the presence of the display and can operate it by only recognizing the image projected in space. Since an aerial display projects the image at a distance far from the physical display, sensors that detect changes in capacitance are not used, and position and movement are measured using one of the three-dimensional distance sensors mentioned above. Since there is no physical monitor directly behind the projected image, this type of aerial display has the advantage of being more hygienic and safer than hover input types, as there is no risk of misjudging the distance and accidentally touching the physical monitor when operating it.

[0018] Although not shown, the room main unit 3 is equipped with a call unit equipped with a microphone and speaker for communicating with visitors through the call unit 12 of the collective entrance unit 1, a display unit for displaying images captured by the camera 14 of the collective entrance unit 1 and various information, and an operation unit for performing answering operations and setting operations.

[0019] The control unit 4 is equipped with a memory unit that stores the relationship between the apartment number and the room master unit 3, a communication IF for the collective entrance unit that communicates with the collective entrance unit 1, a communication IF for the room master unit that communicates with the room master unit 2, a communication IF for the automatic door that controls the unlocking / locking of the electric lock 5a of the automatic door 5, and a control unit CPU that controls the control unit 4, all of which are not shown in the figure.

[0020] The operation of the apartment complex intercom system configured as described above will be explained below. However, explanations will be omitted for conventional operations such as operating the collective entrance unit 1 to call a resident, answering the call from the room master unit 2, and activating the camera 14 in response to the call operation and displaying it on the room master unit 3. Instead, the explanation will focus on the operation of a visitor calling a resident by operating the collective entrance unit 1 and non-contact input device 2 without directly touching them, and the operation of a resident who has returned home unlocking the automatic door 5 and proceeding to their living area, similarly without directly touching the input button.

[0021] When a visitor approaches the collective entrance unit 1, the human presence sensor 15, which detects the approach of a person using infrared or other means, detects the visitor's approach. The display 13 of the collective entrance unit 1 begins to light up. At the same time, the detection signal from the human presence sensor 15 is also sent to the judgment unit 24 of the non-contact input device 2 via the reception control unit 18. This causes the display 21 of the non-contact input device 2 to begin lighting up, and the initial screen, the input standby screen, is displayed. This input standby screen displays buttons, such as "Call," "Unlock," and "Authenticate," that the visitor can use to select the next operation and transition to each operation mode. If the visitor selects "Call," the system transitions to the "Call" operation mode, in which the visitor specifies the room number to call the resident. If the resident returns home and selects "Unlock," the system transitions to the "Unlock" operation mode, in which the PIN code is entered to open the automatic door 5 leading to the residential area. "Authentication" transitions to the "Authentication" operation mode, in which the PIN code is entered to operate the delivery box (not shown) or to confirm a notification identifying the resident. Each operation mode is explained below.

[0022] First, we will explain the case where a visitor calls a resident. When the detection unit 22 detects that the visitor has pressed the "Call" button displayed on the standby screen of the non-contact input device 2, the determination unit 24 transitions to the <Call> operation mode and displays the <Call> mode screen on the display unit 21. For convenience, the following description uses expressions such as "pressing a button." This means that the operator "presses a button" and the detection unit 22 of the non-contact input device 2 identifies the button the operator intended to press. It goes without saying that the actual operation is performed without physical contact. The <Call> mode screen displays buttons such as a numeric keypad, "Confirm," and "Correct." A message guiding the operation, such as "Please press the room number to call," may also be displayed on the screen. The visitor then uses the numeric keypad to specify the room number of the visitor's destination and presses the Confirm button to complete the call destination selection. The room number specified by the visitor is identified by the detection unit 22 and sent to the determination unit 24. The determination unit 24 adds a parameter indicating the operation mode at the time of input, in this case the <call> mode, to the identified room number to create command data, which is then sent to the collective entrance unit 1 via the input device I / F 25. For example, if the room number to be called is 101, the visitor specifies the call destination by pressing "1," "0," and "1" on the numeric keypad and then pressing the "Confirm" button. The determination unit 24 of the non-contact input device 2 adds the parameter "Y," indicating the <call> mode, to the data sent from the detection unit 22 to create command data "101Y," which is then sent to the collective entrance unit 1.

[0023] Then, upon receiving the command data "101Y," the reception control unit 18 of the collective entrance unit 1 determines the parameter "Y" and sends the same signal to the collective entrance unit CPU 16 as when room number "101" is specified in the <call> mode on the operation unit 11 of the collective entrance unit 1. This process executes the same control process as when room 101 is called by physically operating the operation unit 11 of the collective entrance unit 1, i.e., the process of calling the room master unit 3 of room 101 via the control unit 4.

[0024] When the call is received, the room master unit 3 in Room 101 responds, and upon receiving this signal, the collective entrance unit 1 and the non-contact input device 2 transition to <call> mode. The display unit 21 of the non-contact input device 2 indicates that a <call> is in progress, and displays an "end call" button. In <call> mode, the call between the visitor and the resident can be conducted through a microphone and speaker (neither shown) connected to the call unit 12 of the collective entrance unit 1. The call is then ended when the "end call" button is pressed on either the room master unit 3 or the non-contact input device 2, or when a timeout process is performed after a certain period of time has elapsed by a timer built into the control unit 4. When the call ends, the judgment unit 24 of the non-contact input device 2 performs a process to switch the screen on the display unit 21 to the initial screen, which is the input standby screen.

[0025] Next, we will explain the operation when a resident returns home. Note that explanations of parts that are similar to the above-mentioned <Call> operation mode will be omitted where appropriate. The operation is the same as the above until the resident who has returned home approaches the collective entrance device 1 and the input standby screen is displayed on the display unit 21 of the non-contact input device 2. When the detection unit 22 detects that the resident has pressed the "Unlock" button displayed on the standby screen of the non-contact input device 2 to open the automatic door separating the entrance and living area, the judgment unit 24 transitions to the <Unlock> operation mode and displays the <Unlock> mode screen on the display unit 21. The <Unlock> mode screen displays, for example, a numeric keypad and buttons such as "Confirm" and "Correct." At this time, a message guiding the operation, such as "Please enter your PIN number," may also be displayed on the screen.

[0026] The resident then enters a PIN number using the numeric keypad and presses the Confirm button to complete the unlock command. The entered PIN number is identified by the detection unit 22 and sent to the determination unit 24. The determination unit 24 then adds a parameter indicating the operation mode at the time the number was entered—here, the <unlock> mode—to the identified PIN number to create command data, which is then sent to the collective entrance unit 1 via the input device I / F 25. For example, if the PIN number is 1234, the visitor enters the PIN number by pressing "1," "2," "3," and "4" on the numeric keypad and then pressing the Confirm button. The determination unit 24 of the non-contact input device 2 adds the parameter "K," indicating the <unlock> mode, to the data sent from the detection unit 22 to create command data, "1234K," and sends this data to the collective entrance unit 1.

[0027] Upon receiving the command data "1234K," the reception control unit 18 of the collective entrance unit 1 interprets the parameter "K" and transmits the same signal to the collective entrance unit CPU 16 as when the PIN "1234" is entered by physically operating the operation unit 11 of the collective entrance unit 1 in the <Unlock> mode. This results in the same control process as when the unlock PIN is entered using the operation unit 11 of the collective entrance unit 1, i.e., unlocking of the electronic lock attached to the automatic door 5 via the control unit 4. After this, a signal indicating that the unlocking has been completed may be sent from the control unit 4 to the judgment unit 24 of the non-contact input device 2 via the collective entrance unit 1, thereby terminating the <Unlock> operation mode and returning the display on the display unit 21 to the initial screen, i.e., the input standby screen. Alternatively, the <Unlock> operation mode may be terminated when the human presence sensor 15 of the collective entrance unit 1 detects the absence of the operator (resident) or when a timer built into the control unit 4 performs a timeout process after a certain period of time has elapsed. This point can be designed in the same way for all operation modes, not just for <unlocking>.

[0028] Next, the <Authentication> operation mode will be described. This operation mode can be used, for example, to operate a delivery box. An example of an embodiment is shown below. When a resident returns home and selects the <Unlock> operation mode, enters their personal identification number, and performs the unlocking operation, a message informing the resident of the arrival of a package in the delivery box is displayed on the display unit 21 of the non-contact input device 2 and the display unit 13 of the collective entrance unit 1, using, for example, the technology disclosed in Japanese Patent No. 4638751. At the same time, the <Authentication> operation mode is entered, and the judgment unit 24 of the non-contact input device 2 displays buttons for "Receive" and "Cancel" on the display unit 21. If the resident selects "Receive," the operation is identified by the detection unit 22, and the judgment unit 24 displays buttons such as a numeric keypad, "Confirm," and "Correct" on the display unit 21. When the resident enters and confirms the PIN for the delivery box, the judgment unit 24 creates command data by adding the parameter "U" indicating receipt to the PIN for the delivery box and transmits it to the reception control unit 18 of the collective entrance unit 1. The reception control unit 18 judges the parameter "U" and sends the same signal to the collective entrance unit CPU 16 as when a PIN number for the delivery box is specified by physically operating the operation unit 11 of the collective entrance unit 1 in the <receive> mode. This causes the same control processing as when a PIN number for the delivery box is specified on the operation unit 11 of the collective entrance unit 1, i.e., unlocking the delivery box via the control unit 4, to be performed.

[0029] If the detection unit 22 determines that the resident has selected "Cancel" in the above-mentioned "Authentication" operation mode, the determination unit 24 can immediately return to the "Unlock" operation mode to continue unlocking control. In other cases, the "Authentication" operation mode can be terminated when the resident has confirmed the PIN number for the delivery box, or by receiving a signal from the control unit 4 indicating that the delivery box has been unlocked. The display unit 21 of the non-contact input device 2 may return to the initial screen, which is the input standby screen, upon completion of the "Authentication" operation mode, or may be temporarily returned to the "Unlock" operation mode and the electronic lock of the automatic door 5 may be unlocked by having the resident select "Confirm" again. In this case, the previously entered PIN number for the delivery box can be stored in the memory unit 23 of the non-contact input device 2, thereby eliminating the need to enter the PIN number again. In this way, the timing of unlocking the delivery box and the automatic door 5 can be designed in any flexible manner, taking into account the flow of people, which is determined by the individual structure of the apartment building in which the intercom system of the present invention is installed.

[0030] Next, we will describe an example of an embodiment in which a delivery person visiting a delivery location makes a delivery using a delivery box. The delivery person presses the "Authentication" button on the input standby screen of the non-contact input device 2 to enter the <Authentication> operation mode, and buttons such as a numeric keypad, "Delivery," and "Cancel" are displayed on the display unit 21. If "Delivery" is selected, a corresponding signal can be sent to the control unit 4 using the same operations as described above, allowing the delivery person to use the delivery box using the same conventional procedure. The <Authentication> operation mode display screen can also be configured to differ depending on whether the resident returns home and then directly transitions to the <Authentication> operation mode via the <Unlock> operation mode, as described above, or whether the resident directly transitions to the <Authentication> operation mode without passing through the <Unlock> operation mode. If the "Delivery" button is not displayed when the <Authentication> operation mode is entered via the <Unlock> operation mode, operation becomes simpler and more convenient for both the delivery person and the resident.

[0031] This <authentication> operation mode can also be used to confirm individual notifications that identify specific residents. If a message is simply displayed for each room number to the residents, similar to the message notifying the delivery box of the arrival of a package, it is possible to display a notification for each room on the display units 13 and 21 of the collective entrance device 1 and the non-contact input device 2 by confirming the unlocking PIN in the <unlock> mode. However, similar to the delivery reception operation described above, by configuring the system to automatically switch from the <unlock> mode to the <authentication> mode in response to the confirmed unlocking PIN, it is also possible to display a message specifically targeted to each resident living in the same room. In other words, if a notification is required for any of the residents with the room number corresponding to the confirmed unlocking PIN, the system can automatically switch to the <authentication> mode and prompt them to enter their specific PIN, allowing the notification to be sent to that person. The control of the operation in this case can be configured in the same way as the operations described above.

[0032] Up to this point, we have described each operation when operating the apartment building intercom system of the present invention. However, by adding the following configuration to the above configuration, it is possible to prevent the replacement of non-contact input devices and improve security. Specifically, it is preferable to preset a unique ID for identifying each non-contact input device 2 connected to the collective entrance unit 1, and to authenticate that the non-contact input device 2 that sent input data is a device authorized for connection during transmission and reception between the collective entrance unit 1 and the non-contact input device 2. An example of an embodiment related to this is described in detail below. When setting up the intercom system of the present invention, a unique ID is assigned to each non-contact input device 2 authorized for connection to the collective entrance unit 1. The IDs of the authorized non-contact input devices 2 are then stored in advance in the memory unit 17 of the collective entrance unit 1. In each of the above-described operation modes, the judgment unit 24 of the non-contact input device 2 generates command data to be sent to the collective entrance unit, including the ID of the non-contact input device 2. For example, in the above-described call mode, the command data "101Y" is obtained by adding the call mode parameter "Y" to the room number 101 to be called. Alternatively, the ID of the non-contact input device 2, e.g., "-ID-ABCD," can be further added to this to obtain "101Y-ID-ABCD." When the command data contains ID data, the reception control unit 18 of the collective entrance unit 1 checks the ID data stored in the memory unit 17 of the collective entrance unit 1 via the collective entrance unit CPU 16. If the check determines that the transmitted command data was transmitted from a non-contact input device 2 that is permitted to connect, the reception control unit 18 sends the same signal to the collective entrance unit CPU 16 as when the call room number "101" is specified on the operation unit 11 of the collective entrance unit 1, as usual, thereby calling the room master unit 3 of room 101 via the control unit 4.

[0033] If the reception control unit 18 of the multiple entrance device 1 collates the ID data contained in the command data and determines that the IDs do not match and that the received command data was not sent from an input device that is permitted to connect, the reception control unit 18 stops subsequent processing. As a result, no control signal is sent to the multiple entrance device CPU 16, and no call is made. In this case, when the reception control unit 18 stops processing, it may return an error signal to the non-contact input device 2, causing an error message to be displayed on the display unit 21 via the judgment unit 24 of the non-contact input device 2. With the above configuration, it is possible to prevent important security operations such as "calling" and "unlocking" from being performed from other input devices that are not permitted to connect to the intercom system.

[0034] In this example, the ID of the non-contact input device 2 is transmitted as part of the command data, and ID authentication is performed when the collective entrance device 1 processes the command data, but it goes without saying that the timing for ID authentication is not limited to this. For example, to avoid cumbersome processing, ID authentication may be limited to only processes that require extremely high security, such as <unlock>, and ID authentication may be performed by the reception control unit 18 of the collective entrance device 1 instructing the determination unit 24 of the non-contact input device 2 to transmit the ID only when the reception control unit 18 determines that the command data includes an <unlock> parameter.
