[System overview]
The opening/closing system according to the present disclosure is a system for controlling an opening/closing body of a building. In the present disclosure, a building refers to a building used for people to live or engage in some kind of activity. The building may be a residence, for example a single-family house or an apartment complex. Alternatively, the building may be a place where various public facilities such as offices, schools, and restaurants are provided. In the present disclosure, an opening/closing body refers to fittings installed so that people or objects can pass between the inside and outside of a building. The opening/closing body may be, for example, a door such as a sliding door, a swinging door, or a folding door, a shutter, or a window. The opening/closing body may have an automatic opening/closing function.

The opening/closing system controls the opening/closing body so that the opening/closing body opens within a limited opening width for visitors to the building. The opening width is the distance between the frame to which the opening/closing body is attached and the outer edge of the opening/closing body, and varies depending on the opening/closing operation of the opening/closing body. The opening width when the opening/closing body is closed is 0 or approximately 0. "Limited opening width" refers to an opening width smaller than the maximum opening width of the opening/closing body. In one example, the closure system limits the opening width of the closure such that a visitor cannot enter the building but can make contact indoors. This allows building users to receive contact from visitors while maintaining indoor security, including themselves. In the present disclosure, a user refers to a person who uses a building, such as a resident. Contact may be the delivery of tangible objects such as luggage, or the transmission of information (for example, face-to-face meetings, conversations, etc.). Introducing an opening/closing system allows, for example, a delivery person to deliver a package to a user of a building even if the user is absent or unavailable. In other words, the opening/closing system can realize safe placement of the package by placing the package indoors while avoiding the delivery person from entering the house.

[System configuration]
The configuration of an example opening/closing system 1 will be described with reference to FIGS. 1 and 2. FIG. 1 is a diagram showing an example of the overall configuration of an opening/closing system 1. As shown in FIG. FIG. 2 is a diagram showing an example of the functional configuration of the opening/closing system 1. As shown in FIG.

In one example, the opening/closing system 1 includes at least one user terminal 10, a server 20, at least one delivery person terminal 30, and at least one door system 40. These devices and systems can send and receive data to and from each other via the communication network NW. The communication network NW may be configured to include at least one of the Internet and an intranet. The communication network NW may be a wired network or a wireless network. At least a portion of the wireless network may be implemented using near field communication (NFC) such as WiFi (registered trademark), Bluetooth (registered trademark), ZigBee (registered trademark), or the like.

The user terminal 10 is a computer used by users of the building. The user terminal 10 is a computer operated by a user. The user terminal 10 is, for example, a mobile terminal such as a smartphone, a tablet terminal, a wearable terminal, or a laptop computer.

The server 20 is a computer that manages the opening/closing system 1 in an integrated manner. In one example, the server 20 is configured by a large computer such as a business server. Server 20 may be comprised of one or more computers. When a plurality of computers are used, one logical server 20 is configured by connecting these computers to each other via a communication network. Further, the server 20 may be placed on the Internet or the cloud.

The delivery person terminal 30 is a computer used by the delivery person. A delivery person is an example of a visitor, and the delivery person terminal 30 is an example of a visitor terminal. The delivery person terminal 30 is, for example, a mobile terminal such as a smartphone, a tablet terminal, or a wearable terminal.

Door system 40 is a control system that directly controls building doors 41. In one example, door system 40 includes a door 41, a camera 42, and a controller 43. Door system 40 may be configured to include smart lock or smart doorbell functionality. The door 41 is an example of an opening/closing body. The camera 42 is an example of an imaging device that photographs the area around the door 41. For example, a camera 42 may be provided to record the faces and actions of visitors, such as delivery personnel. The camera 42 is provided indoors or outdoors. The control device 43 is a device that comprehensively manages the door system 40. For example, the control device 43 has an automatic lock/unlock function for the door 41 and a function to limit the opening width of the door 41. The control device 43 may have a function of automatically opening and closing the door 41, or may have an auto-assist function that allows a person to open the door 41 with a light force. The control device 43 outputs a predetermined control signal to one or more actuators related to the locking or opening/closing operation of the door 41 to operate each actuator. In one example, the control device 43 further has the function of controlling the camera 42.

The user terminal 10, the server 20, the delivery person terminal 30, and the control device 43 are all equipped with a hardware configuration for realizing at least a part of the opening/closing system 1. In one example, the hardware configuration includes a processor, memory, storage, communication ports, and input/output ports. The number of each of these hardware elements may be one or two or more. The processor runs an operating system and application programs. The storage is composed of storage media such as hard disks and non-volatile semiconductor memories, and stores various programs and data. The memory temporarily stores programs loaded from storage or results of operations performed by the processor. A processor functions as an individual functional module by working with memory to execute programs. The communication port performs data communication with other devices via the communication network NW according to instructions from the processor. The input/output port inputs and outputs electrical signals to and from input/output devices such as a keyboard, mouse, monitor, and touch panel according to instructions from the processor.

The program for implementing the opening/closing system 1 includes program codes for implementing each functional module of the opening/closing system 1. In one example, the program is divided into multiple parts corresponding to the user terminal 10, server 20, delivery person terminal 30, and control device 43, and installed in each computer or device. Each program may be provided after being permanently recorded on a non-temporary recording medium such as a CD-ROM, DVD-ROM, or semiconductor memory. Alternatively, each program may be provided via a communication network as a data signal superimposed on a carrier wave. The provided program is stored in storage. The processor cooperates with the memory to execute the program, thereby realizing the corresponding functional module.

The functional configuration of the opening/closing system 1 will be explained with reference to FIG. 2. User terminal 10 includes a processor 101 and storage 102. In one example, the processor 101 functions as the notification management unit 11 and the key setting unit 12. The notification management unit 11 is a functional module that manages various notifications from other devices. The key setting unit 12 is a functional module that requests the server 20 for key information, which is electronic data used to unlock the door 41, and sets the key information received from the server 20. The key setting unit 12 may store the key information in the storage 102 as a master key.

The server 20 includes a processor 201 and a storage 202. In one example, the processor 201 functions as the key generation unit 21 and the image storage unit 22. The key generation unit 21 is a functional module that generates key information based on a request from the user terminal 10. In one example, the key generation unit 21 transmits the generated key information to the user terminal 10 and the delivery person terminal 30. This key generation section 21 is an example of a key transmission section. The image storage unit 22 is a functional module that stores image data representing images taken by the camera 42 in the storage 202.

Delivery person terminal 30 includes a processor 301 and storage 302. In one example, the processor 301 functions as a notification sending unit 31, a key storage unit 32, and an unlock requesting unit 33. The notification sending unit 31 is a functional module that sends a delivery notice indicating that a package will be delivered to the user to the user terminal 10. The key storage unit 32 is a functional module that stores the key information sent from the server 20 in the storage 302 as a copy key. The unlock request unit 33 is a functional module that requests the control device 43 to unlock the door 41.

The control device 43 includes a processor 401 and a storage 402. In one example, the processor 401 functions as a biometric authentication section 431, a key management section 432, a door control section 433, and a camera control section 434. The biometric authentication unit 431 is a functional module that executes authentication processing based on the visitor's biometric information. The key management unit 432 is a functional module that executes processing related to key information. In one example, the key management unit 432 stores key information in the storage 402 as a master key. Further, the key management unit 432 receives the copy key transmitted from the delivery person terminal 30, and checks the copy key against the master key. This key management unit 432 is an example of a key receiving unit. The door control unit 433 is a functional module that controls the opening width of the door 41, and is an example of an opening/closing control unit. In one example, the door control unit 433 controls the door 41 so that the door 41 opens within a limited opening width in response to the copy key matching the master key. The camera control unit 434 is a functional module that controls the camera 42, and is an example of a shooting control unit.

[System operation]
Next, an example of the processing procedure of the opening/closing system 1 will be explained with reference to FIGS. 3 and 4, and an opening/closing control method according to the present embodiment will be explained. FIG. 3 is a sequence diagram as a processing flow S1 showing an example of the processing procedure of the opening/closing system 1. FIG. 4 is a flowchart showing an example of door control.

In step S11, the notification management unit 11 of the user terminal 10 receives the advance notification. This advance notice is information that informs the user that the package will be delivered. In one example, the notification sending unit 31 of the delivery person terminal 30 sends a delivery notice to the user terminal 10 in response to the delivery person's operation. In another example, the biometric authentication unit 431 of the control device 43 uses a predetermined device to acquire biometric information of a delivery person who visited a building without sending a delivery notice, and performs biometric authentication based on the biometric information. When this is executed and the delivery person is authenticated, a visit notification is sent to the user terminal 10. As biometric authentication, the biometric authentication unit 431 may perform face authentication or iris authentication using the camera 42, or may perform fingerprint authentication using a fingerprint sensor provided at or near the door 41. The notification management unit 11 obtains a delivery notice or a visit notice as an advance notice.

In step S12, the key setting unit 12 of the user terminal 10 sets the opening/closing mode in response to the advance notice. This opening/closing mode indicates control to open the door 41 within a limited opening width range. In one example, the key setting unit 12 sets the opening/closing mode including the opening width. Therefore, the key setting section 12 is an example of a width setting section. This opening width may be a fixed value such as 200 mm. Alternatively, the key setting unit 12 may dynamically set the opening width of the door 41 based on the source of the advance notice. For example, the key setting unit 12 sets a first opening width when receiving a delivery notice from the delivery person terminal 30, and sets a second opening width smaller than the first opening width when receiving a visit notification from the control device 43. You can also set the opening width. For example, the first opening width may be 200 mm, and the second opening width may be 150 mm.

The advance notice sent from the delivery person terminal 30 to the user terminal 10 is an example of a visit notice that informs the user in advance that a visitor will visit the building. On the other hand, the visit notification sent from the control device 43 of the door system 40 to the user terminal 10 is not a visit notice because it is sent when the visitor visits the building. Therefore, in the above example, the key setting unit 12 sets the first opening width when the user terminal 10 receives a visit notice from the delivery person terminal 30, and sets the second opening width when the user terminal 10 does not receive the visit notice. Set.

In step S13, the key setting unit 12 transmits a key request, which is a data signal for requesting generation of key information, to the server 20. For example, the key setting unit 12 transmits a key request including an open/close mode. In the server 20, the key generation unit 21 receives the key request.

In step S14, the key generation unit 21 of the server 20 generates key information based on the key request. In one example, the key generation unit 21 generates key information including an open/close mode. The key generation unit 21 may generate key information that further includes a one-time password. The key generation unit 21 may set a predetermined validity period for the one-time password.

In step S15, the key generation unit 21 transmits the key information to the user terminal 10 and the delivery person terminal 30. In the user terminal 10, the key setting unit 12 receives the key information. The key setting unit 12 may store the key information in the storage 102 as a master key. In the delivery person terminal 30, the key storage unit 32 receives the key information.

In step S16, the key setting unit 12 transfers the key information to the control device 43 based on a user operation or automatically. In the control device 43, the key management unit 432 receives the key information.

In step S17, the key management unit 432 of the control device 43 stores the key information in the storage 402 as a master key. By acquiring the master key, the control device 43 can accept requests from the delivery person terminal 30 and control the door 41. Therefore, it can be said that the master key is information for realizing remote control of the door 41 by the user.

In step S18, the key storage unit 32 of the delivery person terminal 30 stores the key information in the storage 302 as a copy key. By acquiring the copy key, the delivery person terminal 30 can request the control device 43 to control the door 41. As shown in steps S15 and S18, the key generation unit 21 transmits the key information based on the request from the user terminal 10 to the delivery person terminal 30, and causes the delivery person terminal 30 to store the key information.

Step S19 and subsequent processing are executed when the delivery person visits the building. In step S19, the unlock request unit 33 of the delivery person terminal 30 transmits the copy key to the control device 43. In one example, the unlock request unit 33 reads a copy key from the storage 302 in response to an operation by a delivery person, and transmits the copy key. In the control device 43, the key management unit 432 receives the copy key.

In step S20, the control device 43 executes door control in response to the copy key. The door control will be explained in detail with reference to FIG.

In step S201, the key management unit 432 compares the copy key with the master key in the storage 402.

As shown in step S202, the process changes depending on whether the copy key matches the master key. If both pieces of key information match (YES in step S202), the process proceeds to step S203, where the door is unlocked and the opening width is controlled. On the other hand, if the copy key does not match the master key (NO in step S202), the control device 43 ends the process without executing the subsequent process. In this case, the door 41 is not unlocked. In one example, the key management unit 432 determines that the copy key does not match the master key even if the one-time password of the copy key has expired.

In step S203, the door control unit 433 unlocks the door 41 in response to the matching of the key information, and limits the opening width of the door 41 based on the opening/closing mode included in the key information. In one example, the door control unit 433 controls the door 41 with a limited opening width so that the delivery person cannot enter the building and the delivery person can place the package inside the building. As a result, the delivery person can open the door 41 within the limited opening width and place the package indoors through the gap. The door control unit 433 may limit the opening width by controlling the actuator of the door 41 or by operating a physical means such as a stopper. The door control unit 433 may automatically open the door 41 by the limited opening width. In one example, the door control unit 433 activates a timer at the time of unlocking, and starts measuring the elapsed time from unlocking as the unlocking time.

In step S204, the camera control unit 434 controls the camera 42 to start capturing images. That is, the camera control unit 434 starts photographing by the camera 42 in response to the door 41 being unlocked based on the received copy key. The image taken may be a video or a plurality of still images taken continuously. The captured image may include the visitor's face or physique as well as a series of movements of the visitor.

In step S205, the door control unit 433 determines whether the door 41 is closed again.

If the door 41 is closed (YES in step S205), the process advances to step S206. In step S206, the door control unit 433 locks the door 41.

In step S207, the door control unit 433 generates a completion notification indicating completion of delivery (delivery person's visit), and transmits the completion notification to the user terminal 10. In the user terminal 10, the notification management unit 11 receives the completion notification and displays the notification according to a user operation or automatically. In one example, the delivery person operates the delivery person terminal 30 to send another delivery notification to the user terminal 10, which may further receive and display the notification. In one example, the door control unit 433 sends a completion notification in response to the door 41 being closed, so that the user can quickly learn that the package has arrived before receiving a delivery notification from the delivery person. I can do it.

If the door 41 is still open (NO in step S205), the process proceeds to step S208. In step S208, the door control unit 433 compares the unlocking time with a predetermined time limit and determines whether the time limit has elapsed. The purpose of this time limit is to deter dishonest acts by delivery personnel, such as trespassing and vandalism. The time limit may be, for example, 30 seconds, and may be set arbitrarily.

If the unlocking time is less than or equal to the time limit (NO in step S208), the process returns to step S205, and the door control unit 433 determines the state of the door 41 again.

If the unlocking time exceeds the time limit (YES in step S208), the process proceeds to step S209. In step S209, the door control unit 433 outputs a warning sound. For example, the door control unit 433 outputs a warning sound from a speaker provided near the door 41. This warning sound is at least part of the abnormality process executed in response to the unlocking time exceeding the time limit. The warning sound can be used to deter delivery personnel who may commit fraudulent acts.

In step S210, the door control unit 433 transmits an abnormality notification to the user terminal 10 as at least part of the abnormality processing. The abnormality notification is electronic data that informs the user of the possibility that a potentially abnormal event has occurred during delivery. In the user terminal 10, the notification management unit 11 receives the abnormality notification and displays the notification according to a user operation or automatically. The user can recognize the notification and take action, such as contacting the delivery company or security company. In addition to or instead of the user terminal 10, the door control unit 433 may send the abnormality notification to a terminal of another party such as a management company or a security company.

As described above, in one example, if the door 41 is unlocked based on the received copy key and then closed again before a predetermined time limit elapses, the door control unit 433 issues a completion notification. It is transmitted to the user terminal 10. This can be said to be normal processing. On the other hand, if the door 41 is not closed again even after the time limit has elapsed after the door 41 was unlocked based on the copy key, the door control unit 433 executes a predetermined abnormality process.

After step S207 or step S210, the process proceeds to step S211. In step S<b>211 , the camera control unit 434 controls the camera 42 to finish photographing, and transmits the image data to the server 20 . In one example, the camera control unit 434 ends shooting in response to the door 41 being closed again, regardless of whether normal processing or abnormal processing is executed. The camera control unit 434 generates image data by associating a given identifier with an image file generated upon completion of photography. The camera control unit 434 transmits the image data to the server 20, and in the server 20, the image storage unit 22 stores the image data in the storage 202. The user can access the server 20 by operating the user terminal 10, display the video or one or more still images indicated by the image data on the user terminal 10, and check the delivery status.

If the key information includes a one-time password, after the door control unit 433 unlocks the door 41, the key management unit 432 invalidates the key information. For example, the key management unit 432 executes the invalidation in response to the door 41 being unlocked (step S203) or the door 41 being closed again (step S205 or S206). In the present disclosure, closing the door 41 again may include locking the door 41 again (step S206). Therefore, the key management unit 432 may be an example of an opening/closing control unit.

As a modification of step S20, instead of or in addition to limiting the opening width in step S203, the door control unit 433 adjusts the opening width restriction to the delivery person based on the image of the delivery person taken by the camera 42. You may also set or reset the settings. For example, the door control unit 433 estimates dimensions (height, shoulder width, chest circumference, etc.) indicating the delivery person's physique based on the image. Next, the door control unit 433 sets or resets the opening width to be smaller than the estimated size so that the delivery person cannot enter the building and the delivery person can place the package inside the building. Then, the door control unit 433 controls the door 41 with the limited opening width.
