Description

The present disclosure relates to a shutter system that opens and closes automatically.

An electric shutter that automatically opens and closes is known. In the electric shutter, the user operates the operation unit to open and close the shutter. In recent years, the number of smart home devices that open and close the shutter by remote control or automatic operation is increasing.

While the user is out of the room through the window provided with the electric shutter, when the shutter is closed by the electric shutter operating device on the indoor side and the shutter is closed, the user opens the shutter from the outside of the room. Because it is not possible, there is a risk that it will be locked out of the room. When performing remote control using a smart home device, there is a risk that the user will be locked out of the room because it is not known that the user is outside the room.

For example, Patent Document 1 describes a shutter system that prevents a user from being locked out or confined. According to the shutter system described in Patent Document 1, a user existing in the vicinity of the opening of the shutter is detected by a motion sensor, and the shutter closing operation is not executed based on the detection result of the user. Has been done.

As shown in FIG. 1, the shutter system 1 includes a shutter S that can be opened and closed, an operating unit 30 that performs a predetermined operation in connection with opening and closing of the shutter S, and a control device 10 that operates the operating unit 30. .. The shutter S electrically opens and closes the opening, and closes the opening to partition a predetermined area around the shutter S. The shutter S shields the outdoor side of a sweep-out window provided in a house or the like, for example. The shutter S is opened and closed by the moving unit 30. The control device 10 controls the operating unit 30 to open and close the shutter S.

The control device 10 receives, for example, a detection unit 11 that detects the presence or movement of a user in an area partitioned by the shutter S, and a release operation that opens the shutter after the closing operation of the shutter S is completed. Communication with the network W, the release unit 12, the control unit 13 that operates the operation unit 30 based on the detection content detected by the detection unit 11, the storage unit 14 in which data and programs related to control are stored, and the network W. A unit 15 is provided.

The detection unit 11 has a detection device such as a sensor as described later, and detects the presence of a user. The operating unit 30 includes a motor as described later, and drives the shutter S to open and close.

When the closing operation in which the shutter S is closed is started, the control unit 13 selects the operation content of the operation unit 30 that limits the closing operation according to the detection content detected by the detection unit 11, and is based on the operation content. Controls the moving unit 30.

The control unit 13 is realized by executing a program (software) by a processor such as a CPU (Central Processing Unit) or a GPU (Graphics Processing Unit). At least a part of each of these functional parts may be realized by hardware such as LSI (Large Scale Integration), ASIC (Application Specific Integrated Circuit), FPGA (Field-Programmable Gate Array), and software and hardware. It may be realized by the cooperation of hardware.

The storage unit 14 is a storage device composed of a storage medium such as a flash memory or an HDD (Hard Disk Drive). The program may be stored in the storage unit 14, or is stored in a removable storage medium such as a flash memory, a DVD, or a CD-ROM. When the storage medium is attached to the drive device, the storage unit 14 is stored. May be installed in.

The control device 10 communicates with the terminal device 40 owned by the user via the network W. The terminal device 40 is composed of, for example, a communicable information terminal device such as a smartphone, a personal computer, a mobile phone, or a tablet terminal. The control device 10 may communicate with the external server 100 via the network W. The server 100 may acquire data such as the detection result detected by the detection unit 11, the control content of the control unit 13, and the operation content of the release unit 12.

The server 100 may be an authentication server that authenticates the user described later. The server 100 may be an external storage having the function of the storage unit 14 via the network W, or may be a device for performing remote control having the function of the control unit 13. The control device 10 may include a notification unit 16 that notifies the user of the operation of the shutter S.

Next, the detailed configuration of the shutter system 1 will be described.

As shown in FIG. 2, in the shutter system 1, the detection unit 11 includes at least one detection device. The detection unit 11 includes, for example, a movement sensor that detects the movement of the user from indoors to the outdoors partitioned by the shutter, and a sensor that detects a factor that causes the user to exist indoors that the shutter partitions.

The detection unit 11 includes, for example, a camera 11A. The camera 11A captures a peripheral region including the opening of the shutter S. The camera 11A is installed on the side where the movement of the user is restricted. The side where movement restriction occurs is the outdoor side when the shutter S separates the indoor and outdoor areas. In the detection unit 11, the camera 11A is a movement sensor that detects the movement of the user. The camera 11A stores the image pickup data in the storage unit 14. The camera 11A creates a file of the image pickup data at predetermined time intervals and stores it in the storage unit 14. When the predetermined period elapses, the camera 11A overwrites the new data sequentially from the old data, and prevents the capacity of the storage unit 14 from becoming tight.

The detection unit 11 may include a motion sensor 11B for detecting the presence of a user. The motion sensor 11B is, for example, an infrared sensor. The motion sensor 11B is provided on the indoor side, for example, and detects the presence of a user in the room. The motion sensor 11B is also provided on the outdoor side. The motion sensors 11B provided on the indoor side and the outdoor side can detect not only the presence of the user but also the movement of the user.

In the detection unit 11, the motion sensor 11B is a movement sensor that detects the movement of the user. As the motion sensor 11B, not only an infrared sensor but also another sensor may be used as long as the presence of the user can be detected.

The detection unit 11 may be provided with a lock sensor 11C for detecting the open / closed state of the lock provided in the window shielded by the shutter S. The lock sensor 11C detects the opening and closing of the crescent lock, for example, when the window is configured as a sliding shoji screen. The lock sensor 11C may be appropriately changed according to the configuration of the window.

The detection unit 11 may include an operation unit 11D that accepts a restriction operation that restricts the closing operation. The detection unit 11 may detect the presence of the user based on the restriction operation in the operation unit 11D. The operation unit 11D may be configured by, for example, an operation button provided according to a predetermined operation, or may be configured by a touch panel. For example, in the operation unit 11D, the user performs a predetermined restriction operation to "go out" before going out of the room through the window.

After the restriction operation is accepted in the operation unit 11D, the notification unit 16 may display that the user is out of the room. When the operation unit 11D is a touch panel, the display unit in the notification unit 16 may be realized in the operation unit 11D.

As the detection unit 11, a contact sensor 11E that detects contact with a person or an object may be used for the shutter S. If a contact is detected by the contact sensor 11E while the shutter S is closing or opening, the drive unit described later is stopped and the shutter S operation is stopped. For example, when the user is outside the room, after the shutter S closing operation is started, the user touches the contact sensor 11E to stop or change the shutter S to the opening operation. In addition to this, the detection unit 11 may detect the lighting on the indoor side and the usage state of the home electric appliance, and detect that the user is present on the indoor side.

The release unit 12 causes the shutter S to open when the shutter S is closed even though the user is present outside the room. The release unit 12 includes an authentication unit that performs biometric authentication of the user. The release unit 12 includes, for example, a camera 12A as an authentication unit. The camera 12A may be shared with the camera 11A of the detection unit 11. The camera 12A, for example, captures a user. The user causes the camera 12A to take an image of the face.

The captured data is used for face recognition of the user when performing the release operation as described later. When the user is locked out by the shutter S on the outdoor side, the user makes a predetermined gesture such as waving his / her hand to cause the camera 12A to take an image. The image pickup data is used as a trigger when performing a release operation as described later. The user authenticates himself / herself by face recognition with the camera 12A in advance. The user authenticates himself / herself by imaging a predetermined gesture with the camera 12A in advance. The predetermined gesture may be arbitrarily set by the user. Face recognition data and gesture data are stored in the storage unit 14 and the server 100.

The release unit 12 may include, for example, a biometric authentication sensor 12B as an authentication unit. The biometric authentication sensor 12B is, for example, a fingerprint sensor, a voice print sensor (microphone), an iris sensor, a vein sensor, or the like. The user authenticates the person in advance by the biometric authentication sensor 12B. The biometric authentication data is stored in the storage unit 14 or the server 100.

The release unit 12 may include, for example, an operation unit 12C as an authentication unit. The operation unit 12C may be, for example, a keyboard for inputting a predetermined password or a touch panel for inputting a predetermined operation. The operation unit 12C may be configured by the user's terminal device 40. The release unit 12 may be configured by the user's terminal device 40.

The notification unit 16 is controlled by the control unit 13. The notification unit 16 includes, for example, a display unit 16A that displays the operation and operation of the shutter S. The display unit is, for example, a display device such as an LCD (Liquid Crystal Display), an organic EL (Electro Luminescence) display, or an LED (Light Emitting Diode) display. The display unit 16A may be configured by the user's terminal device 40. The display unit 16A displays a predetermined display content such as "close the shutter" at the start of the closing operation of the shutter S.

The notification unit 16 may include a speaker 16B that notifies the operation of the shutter S by voice. The speaker 16B reproduces a predetermined voice such as "close the shutter" at the start of the closing operation of the shutter S. The notification unit 16 may include a light emitting unit 16C that emits light by a light emitting body such as an LED. The light emitting unit 16C emits light according to a predetermined light emitting pattern at the start of the closing operation of the shutter S. The notification unit 16 may be configured by the user's terminal device 40. One or more of the notification contents of the notification unit 16 may be combined and notified.

The operating unit 30 is controlled by the control unit 13. The operating unit 30 includes, for example, a driving unit M that drives the shutter to open and close. The drive unit M is composed of, for example, a motor. The operating unit 30 may include the configuration of the notification unit 16. The notification unit 16 functions as an operation unit 30 when the closing operation is restricted.

Next, the processing contents executed by the control unit 13 will be described.

The shutter S is closed by a remote control by a user's smart home device, a detection result based on a rainfall sensor (not shown), a start factor such as a timer, or the like. The shutter S may start the closing operation when the rainfall or the wind speed is equal to or higher than the reference based on the rain / wind forecast and the actual condition information around the current location acquired via the network W.

When the control unit 13 determines that the movement restriction of the user occurs in the area partitioned by the shutter S based on the detection content detected by the detection unit 11 when the closing operation of the shutter S is started. , The moving unit 30 is controlled to limit the closing operation of the shutter S. The movement restriction is, for example, a state in which the shutter S is closed so that the user cannot return to the indoor side. The control unit 13 determines whether or not the user has moved outdoors based on the detection result of the movement sensor.

The control unit 13 uses, for example, the image pickup data of the camera 11A as teacher data, and determines whether or not the user has moved outdoors by machine learning using deep learning by a neural network. The control unit 13 extracts a user from the surrounding scenery, for example, based on the image pickup data of the camera 11A. The control unit 13 recognizes an action including the movement of the user. The control unit 13 recognizes that, for example, the user moves from the indoor side to the outdoor side through the window. The control unit 13 recognizes that, for example, the user moves from the outdoor side to the indoor side through the window.

Based on the recognition result, the control unit 13 determines that the user has returned to the indoor side when the user moves from the window to the outside of the room and moves from the window to the room. The control unit 13 determines that the user is outside the room when it is not detected that the user moves from the window to the outside of the room and moves from the window to the room based on the recognition result. The control unit 13 may recognize the behavior including the movement of the user based on the detection result of the motion sensor 11B.

In the control unit 13, for example, when the user moves from the window to the outside and moves from the window to the room based on the detection results of the motion sensor 11B on the indoor side and the motion sensor 11B on the outdoor side, the user moves into the room. Judge that it has returned to the inside. For example, if it is not detected that the user moves from the window to the outside of the room and moves from the window to the inside of the room based on the detection result, the control unit 13 determines that the user is outside the room.

The control unit 13 may recognize the behavior including the movement of the user based on the detection result of the lock sensor 11C. For example, when the lock is released by the detection result of the lock sensor 11C, the control unit 13 estimates that the user has moved from the indoor side to the outdoor side through the window. For example, when the lock is closed by the detection result of the lock sensor 11C after the lock is released, the control unit 13 estimates that the user has returned from the outdoor side to the indoor side through the window. The control unit 13 estimates that the user may be outside the room, for example, if it is not detected that the lock is closed after the lock is released by the detection result of the lock sensor 11C.

The control unit 13 may recognize an action including the movement of the user based on the operation content of the operation unit 11D. When the operation unit 11D receives an operation to the effect that the user goes out to the outside of the room, the control unit 13 determines that the user is outside the room. When the operation for canceling this operation is accepted after the operation for going out in the operation unit 11D, the control unit 13 determines that the user has returned to the indoor side. Based on the operation content of the operation unit 11D, the control unit 13 determines that the user is outside the room if the operation for canceling the operation is not performed after the operation of going out.

In addition, the control unit 13 may determine that the user is outside the room based on the detection result of the lighting on the indoor side and the usage state of the home electric appliance. The control unit 13 may determine the movement or behavior of the user not only by the single detection result of each detection device described above but also by the combination of the detection results of at least one or more detection devices.

The control unit 13 may determine that the user is outside the room based on the detection result of the contact sensor 11E. When the control unit 13 controls the drive unit M to start the closing operation of the shutter S and then detects that the user has touched the shutter S based on the detection result of the contact sensor 11E, the user is in the room. It is determined that it exists on the outside.

When the closing operation is started, the control unit 13 selects the operation content of the operation unit that limits the closing operation according to the detection content detected by the detection unit 11. The control unit 13 operates the operation unit 30 based on the selected operation content. The control unit 13 controls the operation unit 30 to limit the closing operation when it is determined that a user exists indoors based on the detection result of each sensor.

The control unit 13 controls the operation unit 30 to limit the closing operation when it is determined that the user has moved outdoors based on the detection results of the movement sensor such as the camera 11A or the motion sensor 11B. .. When limiting the closing operation, the control unit 13 controls, for example, to stop the driving unit M and not start the closing operation. At this time, the control unit 13 may cause the notification unit 16 to perform a predetermined notification for limiting the closing operation when it is determined that the movement restriction of the user occurs in the area based on the detection content.

When the control unit 13 determines that the user exists outside the room and the operation to start the closing operation is received by another user, the control unit 13 causes the notification unit 16 to notify the notification unit 16 to limit the closing operation. You may. At this time, the control unit 13 may notify the terminal device 40 of another user.

When limiting the closing operation, the control unit 13 may delay the operation of the driving unit M as compared with the normal closing operation and close the shutter S within a predetermined time (for example, several minutes). good. For example, the control unit 13 may control the drive unit M to keep the shutter S in a half-open state for a predetermined time. At this time, the control unit 13 may operate the notification unit 16 to perform a predetermined notification. When the detection unit 11 receives the restriction operation for limiting the closing operation in the operation unit 11D, the control unit controls the operation unit 30 to limit the closing operation based on the restriction operation.

When the control unit 13 determines that the user exists on the indoor side or does not exist on the outdoor side based on the detection result of the detection unit 11 when the closing operation is started, the control unit 13 determines that the user does not exist on the outdoor side. The drive unit M is controlled to close the shutter S.

In the unlikely event that the user is locked out of the room after the closing operation of the shutter S is completed, the user can operate the release unit 12 to open the shutter S. The opening operation includes driving the drive unit M to release the shutter S, releasing the lock together with the release of the shutter S, and notifying the notification unit 16.

The user operates, for example, the release unit 12 provided on the outdoor side. For example, the user performs a predetermined gesture set in advance toward the camera 12A, and initiates the opening operation using the gesture as a trigger. The user, for example, causes the camera 12A to take an image of the face and performs face recognition. The user performs biometric authentication using the above-mentioned biometric authentication sensor 12B in the release unit 12. The user operates the operation unit 12C in the release unit 12 to perform authentication. When the user has the terminal device 40, the user may operate the terminal device 40 to perform operations such as face authentication, biometric authentication, and release operation to perform authentication.

The control unit 13 controls the operation unit 30 to perform the opening operation based on the release operation received by the release unit 12. The control unit 13 drives the drive unit M to open the shutter S, for example, based on the release operation. When the lock is closed and the control unit 13 is provided with an actuator for opening and closing the lock, the control unit 13 drives the drive unit M to open the shutter S and controls the actuator to open the lock. May be good.

The control unit 13 controls the operation unit 30 to perform the opening operation based on the biometric authentication authenticated by the release unit 12. The control unit 13 may control the operation unit 30 to perform the opening operation when two or more release operations received by the release unit 12 are performed. The control unit 13 may unlock the front door based on the release operation received by the release unit 12. The control unit 13 may allow the user to select the content of the open operation at the operation stage of the release unit 12 by the terminal device 40. When the release operation is performed, the control unit 13 may relearn the detection result before the release to improve the determination accuracy.

Next, the processing executed by the control device 10 will be described.

FIG. 3 shows a flow chart of the process executed by the control device 10. The detection unit 11 detects a start condition for starting the closing operation of the shutter S (step S100). When the closing operation is started, the control unit 13 determines whether or not the detection content limiting the closing operation is detected based on the detection result of the detection unit 11 (step S102). When the detection unit 11 detects the detection content that limits the closing operation (step S102: Yes), the control unit 13 selects the operation content of the operation unit 30 that restricts the closing operation according to the detected detection content. The moving unit 30 is operated (step S104). After that, the process is returned to step S102.

When the detection unit 11 does not detect the detection content that limits the closing operation in step S102 (step S102: No), the control unit 13 drives the driving unit M to execute the closing operation of the shutter S (step S106). After closing the shutter S, the control unit 13 drives the drive unit M to open the shutter S and open the shutter S when the release operation is executed in the release unit 12 (step S108: Yes). (Step S110). After closing the shutter S, the control unit 13 ends the process when the release operation is not executed in the release unit 12 (step S108: No).

As described above, according to the shutter system 1, when the closing operation of the shutter S is started, the control unit 13 determines whether or not the user is outside the room based on the detection result of the detection unit 11. It is possible to make a determination and limit the closing operation of the shutter S based on the determination result. According to the shutter system 1, since the control unit 13 determines whether or not the user is outside the room, it can be used even when the user is outside the detection range of the sensor or the like and the detection value cannot be obtained. It is possible to determine whether or not the person is outside the room, and it is possible to prevent the user from being locked out.

The embodiment of the present disclosure has been described above. The present disclosure is not limited to the above embodiment, and can be appropriately modified or substituted. For example, the shutter is exemplified as the one provided in the window of a house, but the shutter is not limited to this, and may be a shutter that shields the entrance of a partitioned space such as a garage. The shutter system may not only prevent the user from being locked out on the outdoor side, but may also prevent the user from being restricted in the area such as confinement of the user on the indoor side or the like.

The process executed by the control unit and the authentication based on the release operation may be processed by the server. Further, the detection result and the release operation by the detection unit may be accumulated in the server, and a machine learning database for the user to execute the determination process existing outside the room may be generated. The server may update the program that executes the determination process and update the control device via the network.
