[Technical field]
[0001] The present disclosure relates to an automatically opening and closing shutter system. [Background technology]
[0002] There is known an electric shutter that opens and closes automatically. A user opens and closes the electric shutter by operating an operation unit. In recent years, there has been an increase in the number of electric shutters that open and close remotely or automatically using smart home devices.
[0003] If a user goes outside through a window equipped with electric shutters and the shutters are closed using an electric shutter operating device inside the room, the user cannot open the shutters from outside the room, and there is a risk that the user will be locked out. When remotely operating the shutters using smart home devices, there is a risk that the user will be locked out because it is not possible to know that the user has gone outside the room.
[0004] For example, Patent Document 1 describes a shutter system that prevents users from being locked out or trapped inside. The shutter system described in Patent Document 1 is configured to detect a user near the shutter opening using a human sensor, and not to execute the shutter closing operation based on the user detection result.

According to the shutter system described in Patent Document 1, there is also an issue that after the shutter is closed, the user who has been locked out or trapped cannot open the shutter.
[0007] An object of the present disclosure is to provide a shutter system that can prevent restrictions on the movement of a user from occurring when the shutter is closed. [Means for solving the problem]
[0008] The present disclosure provides a device that includes a shutter that can be opened and closed, a detection unit that detects the actions of a user in an area partitioned by the shutter, an operation unit that performs a predetermined operation in relation to the opening and closing of the shutter, and a control unit, The detection unit has a first sensor that detects the presence of a user in an area on one side partitioned by the shutter, and a second sensor that detects the presence of a user in an area on the other side partitioned by the shutter, and the control unit When the closing operation of the shutter is started, The first sensor and the second sensor The closing operation is restricted according to the contents of the detection. 。 [Brief description of the drawings]
[0009] [Figure 1] 1 is a block diagram showing a configuration of a shutter system according to an embodiment; [Diagram 2] FIG. 2 is a block diagram showing a detailed configuration of the shutter system. [Diagram 3] 4 is a flowchart showing a flow of processing executed in the shutter system. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0010] The shutter system prevents the user from being restricted in movement when the shutter is automatically opened and closed.
[0011] As shown in Fig. 1, the shutter system 1 includes a shutter S that can be opened and closed freely, an operating unit 30 that performs a predetermined operation related to the 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 by closing the opening, a predetermined area around the shutter S is partitioned off. The shutter S is, for example, for blocking the outside of a sliding window installed in a house or the like. The shutter S is opened and closed by the operating unit 30. The control device 10 controls the operating unit 30 to open and close the shutter S.
[0012] The control device 10 includes, for example, a detection unit 11 that detects the presence and movement of a user in the area partitioned off by the shutter S, a release unit 12 that accepts a release operation to perform an opening operation to open the shutter after the closing operation of the shutter S is completed, a control unit 13 that operates the operation unit 30 based on the detection content detected by the detection unit 11, a memory unit 14 in which data and programs related to control are stored, and a communication unit 15 that communicates with the network W.
[0013] The detection unit 11 has a detection device such as a sensor as described later, and detects the presence of a user. The operation unit 30 has a motor as described later, and drives the shutter S to open and close it.
[0014] When the closing operation of closing the shutter S is started, the control unit 13 selects the operation content of the operation unit 30 that limits the closing operation in accordance with the detection content detected by the detection unit 11, and controls the operation unit 30 based on the operation content.
[0015] The control unit 13 is realized by a processor such as a CPU (Central Processing Unit) or a GPU (Graphics Processing Unit) executing a program (software). At least a part of these functional units may be realized by hardware such as an LSI (Large Scale Integration), an ASIC (Application Specific Integrated Circuit), or an FPGA (Field-Programmable Gate Array), or may be realized by a combination of software and hardware.
[0016] The storage unit 14 is a storage device configured with a storage medium such as a flash memory, a hard disk drive (HDD), etc. The program may be stored in the storage unit 14, or may be stored in a removable storage medium such as a flash memory, a DVD, a CD-ROM, etc., and may be installed in the storage unit 14 by mounting the storage medium in a drive device.
[0017] The control device 10 communicates with a terminal device 40 owned by a user via a network W. The terminal device 40 is configured by, 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 an 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.
[0018] The server 100 may be an authentication server that authenticates a user, which will be 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 that performs remote operation 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.
[0019] Next, a detailed configuration of the shutter system 1 will be described.
[0020] 2, the detection unit 11 in the shutter system 1 includes at least one detection device. The detection unit 11 includes, for example, a movement sensor that detects the movement of a user from the indoors separated by the shutters to the outdoors, and a sensor that detects the cause of the user's presence in the indoors separated by the shutters.
[0021] The detection unit 11 includes, for example, a camera 11A. The camera 11A captures an image of the surrounding area including the opening of the shutter S. The camera 11A is installed on the side where the movement of the user is restricted. When the shutter S separates the indoor area from the outdoor area, the side where the movement is restricted is the outdoor side. In the detection unit 11, the camera 11A is a movement sensor that detects the movement of the user. The camera 11A stores the captured image data in the memory unit 14. The camera 11A files the captured image data at predetermined time intervals and stores the files in the memory unit 14. When a predetermined period has passed, the camera 11A sequentially overwrites the old data with new data to prevent the capacity of the memory unit 14 from becoming full.
[0022] The detection unit 11 may include a human presence sensor 11B that detects the presence of a user. The human presence sensor 11B is, for example, an infrared sensor. The human presence sensor 11B is provided, for example, on the indoor side and detects the presence of a user in the room. The human presence sensor 11B is also provided on the outdoor side. The human presence sensors 11B provided on both the indoor and outdoor sides can detect not only the presence of a user but also the movement of the user.
[0023] In the detection unit 11, the human presence sensor 11B is a movement sensor that detects the movement of a user. The human presence sensor 11B is not limited to an infrared sensor, and other sensors may be used as long as they can detect the presence of a user.
[0024] The detection unit 11 may be provided with a lock sensor 11C that detects the open / closed state of a lock installed on a window covered by the shutter S. For example, when the window is configured as a sliding door, the lock sensor 11C detects the open / closed state of a crescent lock. The lock sensor 11C may be appropriately changed according to the configuration of the window.
[0025] The detection unit 11 may include an operation unit 11D that receives a limiting operation for limiting the closing operation. The detection unit 11 may detect the presence of a user based on the limiting operation on the operation unit 11D. The operation unit 11D may be configured, for example, with operation buttons provided in accordance with predetermined operations, or may be configured with a touch panel. For example, the user performs a predetermined limiting operation on the operation unit 11D to "go outside" before going outside through the window.
[0026] After the limiting operation is accepted by operation unit 11D, a display that the user has gone outside the room may be displayed on notification unit 16. When operation unit 11D is a touch panel, the display unit of notification unit 16 may be realized by operation unit 11D.
[0027] The detection unit 11 may use a contact sensor 11E that senses contact of a person or object with the shutter S. When the contact sensor 11E detects contact while the shutter S is performing a closing or opening operation, a drive unit described below is stopped and the operation of the shutter S is stopped. For example, when a user is on the outside of the room, after the closing operation of the shutter S is started, the user touches the contact sensor 11E to stop the shutter S or change it to an opening operation. The detection unit 11 may also detect the use state of lighting and home appliances on the indoor side and detect that a user is on the indoor side.
[0028] The release unit 12 opens the shutter S when the shutter S is closed even though a 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 the authentication unit. The camera 12A may be shared with the camera 11A of the detection unit 11. The camera 12A captures, for example, an image of the user. The user causes the camera 12A to capture an image of the face.
[0029] The captured image data is used for face authentication of the user when performing the unlocking operation as described below. When the user is locked out by the shutter S on the outside of the room, the user makes a predetermined gesture such as waving a hand to have the camera 12A capture an image of the user. The captured image data is used as a trigger when performing the unlocking operation as described below. The user is authenticated in advance by face authentication using the camera 12A. The user is authenticated in advance by having the camera 12A capture an image of a predetermined gesture. The predetermined gesture may be arbitrarily set by the user. The face authentication data and gesture data are stored in the memory unit 14 and the server 100.
[0030] 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 voiceprint sensor (microphone), an iris sensor, a vein sensor, or the like. The user performs identity authentication in advance using the biometric authentication sensor 12B. The biometric authentication data is stored in the storage unit 14 or the server 100.
[0031] 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 PIN number or a touch panel for inputting a predetermined operation. The operation unit 12C may be configured by a terminal device 40 of a user. The release unit 12 may be configured by a terminal device 40 of a user.
[0032] The notification unit 16 is controlled by the control unit 13. The notification unit 16 includes a display unit 16A that displays information related to the operation and manipulation of the shutter S, for example. The display unit is 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 "Closing the shutter" when the closing operation of the shutter S starts.
[0033] The notification unit 16 may include a speaker 16B that notifies the operation of the shutter S by voice. The speaker 16B plays a predetermined voice such as "Closing the shutter" when the closing operation of the shutter S starts. The notification unit 16 may include a light-emitting unit 16C that emits light using a light-emitting body such as an LED. The light-emitting unit 16C emits light in a predetermined light-emitting pattern when the closing operation of the shutter S starts. The notification unit 16 may be configured by the user's terminal device 40. The notification contents of the notification unit 16 may be a combination of one or more.
[0034] The operation unit 30 is controlled by the control unit 13. The operation unit 30 includes, for example, a drive unit M that drives the shutter to open and close. The drive unit M is configured with, for example, a motor. The operation unit 30 may include the configuration of the notification unit 16. The notification unit 16 functions as the operation unit 30 when the closing operation is restricted.
[0035] Next, the process executed by the control unit 13 will be described.
[0036] The shutter S starts to close when a trigger such as a remote operation by a user's smart home device, a detection result based on a rainfall sensor (not shown), or a timer starts the closing operation. The shutter S may start to close when the amount of rain or wind speed is equal to or higher than a standard based on a rain and wind forecast and actual information around the current location acquired via the network W.
[0037] When the control unit 13 determines, based on the contents of detection by the detection unit 11, that a restriction on the movement of the user will occur in the area partitioned by the shutter S when the closing operation of the shutter S starts, the control unit 13 controls the operation unit 30 to restrict the closing operation of the shutter S. The restriction on movement is, for example, a state in which the shutter S is closed and the user is locked out from returning to the inside of the room. The control unit 13 determines, based on the detection result of the movement sensor, whether or not the user has moved outdoors.
[0038] The control unit 13, for example, uses the imaging data of the camera 11A as teacher data and determines whether the user has moved outdoors by machine learning using deep learning with a neural network. The control unit 13, for example, extracts the user from the surrounding scenery based on the imaging data of the camera 11A. The control unit 13 recognizes the user's behavior including movement. For example, the control unit 13 recognizes that the user moves from the indoor side to the outdoor side through a window. For example, the control unit 13 recognizes that the user moves from the outdoor side to the indoor side through a window.
[0039] The control unit 13 determines that the user has returned to the indoor side when the user moves from the window to the outside based on the recognition result and moves from the window to the inside. The control unit 13 determines that the user is present on the outdoor side when the control unit 13 does not detect that the user moves from the window to the outside based on the recognition result and moves from the window to the inside. The control unit 13 may recognize the user's behavior including the user's movement based on the detection result of the human presence sensor 11B.
[0040] For example, the control unit 13 determines that the user has returned to the inside of the room when the user moves outside through a window and then moves inside through a window based on the detection results of the indoor-side human presence sensor 11B and the outdoor-side human presence sensor 11B. For example, when the control unit 13 does not detect that the user has moved outside through a window and then moved inside through a window based on the detection results, it determines that the user is present on the outside of the room.
[0041] 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 based on the detection result of the lock sensor 11C, the control unit 13 presumes that the user has moved from the indoor side to the outdoor side through the window. For example, when the lock is closed based on the detection result of the lock sensor 11C after the lock is released, the control unit 13 presumes that the user has returned from the outdoor side to the indoor side through the window. For example, when the lock is released based on the detection result of the lock sensor 11C and the lock is not detected to be closed, the control unit 13 presumes that the user may be on the outdoor side.
[0042] The control unit 13 may recognize the user's behavior including movement based on the operation content of the operation unit 11D. When an operation to the effect that the user is going out to the outside of the room is received on the operation unit 11D, the control unit 13 determines that the user is present on the outside of the room. When an operation to cancel the operation to go out is received on the operation unit 11D after the operation to go out, the control unit 13 determines that the user has returned to the inside of the room. Based on the operation content of the operation unit 11D, when an operation to cancel the operation is not performed after the operation to go out, the control unit 13 determines that the user is present on the outside of the room.
[0043] In addition, the control unit 13 may determine that a user is present on the outside of the room based on the detection results of the lighting on the inside of the room and the usage state of home appliances. The control unit 13 may determine the movement and behavior of the user based on a combination of detection results of at least one or more detection devices, rather than based on a single detection result of each of the above detection devices.
[0044] The control unit 13 may determine that a user is present on the outside of the room based on the detection result of the contact sensor 11E. After the control unit 13 controls the drive unit M to start the closing operation of the shutter S, if the control unit 13 detects that the user has touched the shutter S based on the detection result of the contact sensor 11E, the control unit 13 determines that the user is present on the outside of the room.
[0045] 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. When the control unit 13 determines that a user is present indoors based on the detection results of each sensor, it controls the operation unit 30 to limit the closing operation.
[0046] For example, when the control unit 13 determines that the user has moved outdoors based on the detection results of movement sensors such as the camera 11A and the human presence sensor 11B, it controls the operation unit 30 to restrict the closing operation. When restricting the closing operation, the control unit 13 controls, for example, the drive unit M to stop so as not to start the closing operation. At this time, when the control unit 13 determines based on the detection content that a restriction on the movement of the user will occur in the area, it may cause the notification unit 16 to issue a predetermined notification restricting the closing operation.
[0047] When the control unit 13 determines that a user is present on the outside of the room, and receives an operation to start a closing operation from another user, the control unit 13 may cause the notification unit 16 to issue a notification that the closing operation is to be restricted. At this time, the control unit 13 may cause the terminal device 40 of the other user to issue a notification.
[0048] When restricting the closing operation, the control unit 13 may, for example, delay the operation of the drive unit M compared to a normal closing operation, and close the shutter S for a predetermined time (for example, several minutes). The control unit 13 may, for example, 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 issue a predetermined notification. When a limiting operation to limit the closing operation is accepted by the operation unit 11D in the detection unit 11, the control unit controls the operation unit 30 based on the limiting operation to limit the closing operation.
[0049] When the closing operation is started, if the control unit 13 determines based on the detection result of the detection unit 11 that a user is present on the inside of the room, or if it determines that a user is not present on the outside of the room, it controls the drive unit M to perform the closing operation of the shutter S.
[0050] 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 perform the opening operation of the shutter S. The opening operation includes driving the drive unit M to open the shutter S, releasing the lock together with the opening of the shutter S, and notifying the notification unit 16.
[0051] The user operates, for example, the release unit 12 provided on the outside of the room. The user makes a predetermined gesture, for example, toward the camera 12A, which triggers the opening operation to begin. The user, for example, has the camera 12A capture an image of the face and performs facial authentication. The user performs biometric authentication using the biometric authentication sensor 12B described above in the release unit 12. The user performs authentication by operating the operation unit 12C in the release unit 12. If the user has a terminal device 40, the user may operate the terminal device 40 to perform operations such as facial authentication, biometric authentication, and release operation to perform authentication.
[0052] The control unit 13 controls the operation unit 30 to perform an opening operation based on the release operation received by the release unit 12. For example, the control unit 13 drives the drive unit M to open the shutter S based on the release operation. When the lock is closed and an actuator for opening and closing the lock is provided, the control unit 13 may drive the drive unit M to open the shutter S and control the actuator to open the lock.
[0053] The control unit 13 controls the operation unit 30 to perform an 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 an opening operation when two or more release operations accepted by the release unit 12 have been performed. The control unit 13 may unlock the front door based on the release operations accepted by the release unit 12. The control unit 13 may allow the user to select the content of the opening operation at the stage of operating the release unit 12 by the terminal device 40. When a release operation has been performed, the control unit 13 may re-learn the detection result before release to improve the determination accuracy.
[0054] Next, the processing executed by the control device 10 will be described.
[0055] 3 shows a flow of processing executed by the control device 10 in the form of a flowchart. 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 a detection content that limits the closing operation has been detected based on the detection result of the detection unit 11 (step S102). If the detection unit 11 detects a detection content that limits the closing operation (step S102: Yes), the control unit 13 selects an operation content of the operation unit 30 that limits the closing operation according to the detected detection content, and operates the operation unit 30 (step S104). After that, the processing returns to step S102.
[0056] If the detection unit 11 does not detect any detection content that restricts the closing operation in step S102 (step S102: No), the control unit 13 drives the drive unit M to execute the closing operation of the shutter S (step S106). If the release operation is executed in the release unit 12 after the shutter S is closed (step S108: Yes), the control unit 13 drives the drive unit M to execute the opening operation of the shutter S to open the shutter S (step S110). If the release operation is not executed in the release unit 12 after the shutter S is closed (step S108: No), the control unit 13 ends the process.
[0057] As described above, according to the shutter system 1, when the closing operation of the shutter S is started, the control unit 13 judges whether or not a user is present on the outside of the room based on the detection result of the detection unit 11, and based on the judgment result, it is possible to restrict the closing operation of the shutter S. According to the shutter system 1, since the control unit 13 judges whether or not a user is present on the outside of the room, even in a state in which a user is present outside the detection range of a sensor or the like and a detection value cannot be obtained, it is possible to determine whether or not a user is present on the outside of the room, and it is possible to prevent the user from being locked out.
[0058] An embodiment of the present disclosure has been described above. The present disclosure is not limited to the above embodiment, and can be modified or replaced as appropriate. For example, the shutter is exemplified as being installed on a window of a house, but is not limited thereto, and may be used to block the entrance of a partitioned space such as a garage. The shutter system may not only prevent users from being locked out on the outside of the room, but also prevent users from being confined on the inside of the room, or other users from being restricted in their movements within the area.
[0059] The process executed by the control unit and the authentication based on the release operation may be processed by the server. Furthermore, the detection result by the detection unit and the release operation may be stored in the server, and a machine learning database may be generated for executing a process of determining whether a user is present on the outside of the room. The server may update the program that executes the determination process and update the control device via the network. [Explanation of symbols]
