[Figure 10]10 shows examples of images displayed on each door depending on the operation of the movable door. DETAILED DESCRIPTION OF THE INVENTION
[0011] First, an overview of an automatic door 100 to which an embodiment of the present invention is applied will be described with reference to Figures 1 and 2. Figure 1 is a front view that schematically shows the automatic door 100 according to an embodiment of the present invention. The automatic door 100 mainly comprises a door section 10 including a movable door that is controlled or driven to open and close, a controller 20 that controls the entire automatic door 100, a sensor 30 (a collective term for an activation sensor 31 and a protection sensor 32) that detects pedestrians, a door engine 40 that generates power, and a power transmission section 50 that transmits power to the door section 10. In the following description, the left-right direction in Figure 1 is defined as the horizontal direction, and the up-down direction in Figure 1 is defined as the vertical direction; however, the automatic door 100 can be installed in any position, and its installation direction is not limited to the example below.
[0012] The door unit 10 includes a first movable door 11L and a second movable door 11R, each of which is movable horizontally; a first fixed door 12L and a second fixed door 12R, which serve as fixed doors overlapping the first movable door 11L and the second movable door 11R when the doors are open; and a guide mechanism 13 that guides the horizontal movement of the first movable door 11L and the second movable door 11R. The first movable door 11L, the second movable door 11R, the first fixed door 12L, and the second fixed door 12R are configured in a vertically elongated rectangular shape with a vertical dimension greater than a horizontal dimension. When the door unit 10 is opened, the first movable door 11L shown on the left in FIG. 1 is moved leftward, and the second movable door 11R shown on the right in FIG. 1 is moved rightward. Furthermore, when the door unit 10 is driven to close, the first movable door 11L is driven to the right and the second movable door 11R is driven to the left, which is the opposite of when the door unit 10 is driven to open. The number and shape of the doors that make up the door unit 10 are not limited to those described above and can be designed appropriately to suit the needs of the installation location. Similarly, the movable direction of the door unit 10 is not limited to the horizontal direction and may be inclined from the horizontal direction.
[0013] The guide mechanism 13 includes a traveling rail 131, door rollers 132, a guide rail 133, and a vibration prevention member 134. The traveling rail 131 is a columnar rail member extending horizontally above the movable doors 11L, 11R over the entire movable range. Two door rollers 132 are provided on the upper part of each of the movable doors 11L, 11R, and each of the movable doors 11L, 11R is suspended on the traveling rail 131. When each of the movable doors 11L, 11R is driven to open or close in the horizontal direction, the door rollers 132 roll on the traveling rail 131, enabling smooth opening and closing operations. The guide rail 133 is a grooved rail member extending horizontally below the movable doors 11L, 11R over the entire movable range. The vibration prevention member 134 protrudes from the bottom of the movable doors 11L, 11R and is fitted into the grooved guide rail 133. When each movable door 11L, 11R is driven to open and close horizontally, the vibration prevention portion 134 moves along the guide rail 133, thereby suppressing vibration of each movable door 11L, 11R in the forward direction (direction perpendicular to the plane of the paper in Figure 1).
[0014] Various parameters related to the opening and closing of the door unit 10 can be set by the controller 20. For example, the opening and closing speed, opening and closing strength, opening width, etc. can be set. The opening and closing speed is the horizontal speed of the first movable door 11L and the second movable door 11R, and the directions of the speeds of the two doors are opposite to each other. Preferably, the magnitude (speed) of the speeds of the two doors is equal, but they may be different. The opening and closing speed may be set to different values for normal opening and closing and other times. For example, in the case of a so-called reversal in which the door unit 10 switches from a normal closing operation to an opening operation to urgently prevent a passerby from being pinched by the closing movable doors 11L and 11R, the speed of the movable doors 11L and 11R during the opening operation may be set to a value different from the speed during normal opening. Furthermore, when the door unit 10 is driven by emergency power supplied from a battery in an emergency when the normal power source is unavailable, such as during a power outage, the opening and closing speeds may be set to values different from those during normal operation.
[0015] The opening / closing strength is the magnitude of the force exerted when the movable doors 11L and 11R are opened or closed, and is controlled by the torque value generated by the motor 42 (described later). As with the opening / closing speed, it is preferable to set the same opening / closing strength for the movable doors 11L and 11R. Alternatively, different opening / closing strengths may be set for normal opening and closing and other times. The opening width is typically the horizontal distance between the first movable door 11L and the second movable door 11R when the door unit 10 is fully open. As shown in FIG. 1, if the movement distance between the fully closed and fully open positions of the first movable door 11L is W1 and the movement distance between the fully closed and fully open positions of the second movable door 11R is W2, the opening width is expressed as W1 + W2. Here, the movement distances W1 and W2 can be individually set within the horizontal dimensions of the automatic door 100. In addition, in an emergency when the normal power source is unavailable, such as during a power outage, the opening width of the door section 10 may be made smaller than normal when the door section 10 is driven by temporary power supplied from a battery, thereby reducing the power consumption caused by opening and closing the door section 10 in an emergency.
[0016] FIG. 1 shows examples of sensors 30, including an activation sensor 31 and a protection sensor 32. The activation sensor 31 is a photoelectric sensor mounted on the surface of the door frame 60 above the door section 10. The activation sensor 31 includes multiple light-emitting elements that project light, such as infrared light, toward the floor and multiple light-receiving elements that receive light reflected from the floor. When an object, such as a pedestrian, approaches the automatic door 100 and blocks the light, the amount of light received by the light-receiving elements changes, enabling the object to be detected. Hereinafter, when the amount of light received by the light-receiving elements of the activation sensor 31 changes significantly due to the object being detected, the activation sensor 31 is said to be in a detection state. When detection information from the activation sensor 31 in the detection state is input to the controller 20, the door engine 40 is driven to open the door section 10. The activation sensors 31 are mounted on both the indoor side (e.g., the front side of the paper in FIG. 1) and the outdoor side (e.g., the back side of the paper in FIG. 1), enabling detection of pedestrians approaching from either side. When it is necessary to distinguish between the two below, they will be referred to as the indoor-side activation sensor and the outdoor-side activation sensor, respectively.
[0017] The activation sensor 31 may be configured to detect a passerby by reflecting radio waves such as microwaves or ultrasonic waves. Alternatively, as shown in FIG. 1 as 31A, the door unit 10 may be activated when a passerby presses a touch plate provided on at least one of the movable doors 11L and 11R. In addition, in tourist facilities, amusement parks, and the like, it is also conceivable that the door unit 10 may be activated by operation by facility staff in addition to or instead of detecting and operating the door unit 10 by a passerby. In such cases, the facility staff can remotely activate the door unit 10 using a control panel provided at a location away from the door unit 10 or an operation terminal capable of communicating with the automatic door 100.
[0018] The protection sensor 32 is a photoelectric sensor provided on the first fixed door 12L and the second fixed door 12R of the door unit 10. The protection sensor 32 includes a light-emitting unit provided on one of the first fixed door 12L and the second fixed door 12R, and a light-receiving unit provided on the other. The light-emitting unit and the light-receiving unit are located at the same height from the floor, and the light-receiving unit receives light, such as infrared light, emitted horizontally from the light-emitting unit. When a pedestrian passes through the door unit 10 while it is open and blocks the light, the amount of light received by the light-receiving unit changes, allowing the pedestrian to be detected. Hereinafter, when the amount of light received by the light-receiving unit of the protection sensor 32 changes significantly due to a pedestrian or other object being detected, the protection sensor 32 is said to be in a detection state. The main purpose of the protection sensor 32 is to provide protection against closure. When the protection sensor 32 detects a pedestrian during the closing operation of the movable doors 11L and 11R, the controller 20 performs reverse control to stop the closing drive and switch to the opening drive. This prevents pedestrians from getting caught between the closing movable doors 11L and 11R. In this closing protection control, by using the detection information of the activation sensor 31, which is also configured as a photoelectric sensor like the protection sensor 32, in addition, the detection accuracy of pedestrians can be improved, further improving safety.
[0019] The protection sensor 32 may be configured to detect passersby by reflecting radio waves such as microwaves or ultrasonic waves. The protection sensor 32 may also be installed in a location different from the fixed doors 12L, 12R. For example, it may be installed on the blind 60 like the activation sensor 31, or on the ceiling near the automatic door 100. Installing multiple such protection sensors 32 increases costs but dramatically improves safety.
[0020] The door engine 40 includes a motor drive unit 41, a motor 42, and a drive pulley 43. The motor drive unit 41 is configured as an intelligent power module (IPM) and generates a voltage or current to drive the motor 42 under the control of the controller 20. The motor 42, which serves as a power source for generating rotational power, can be configured as any of various known motors, but in this embodiment, it is configured as a brushless motor equipped with an encoder using a Hall element, for example. The position of the rotor of the motor 42 detected by the encoder is input to the motor drive unit 41, and a corresponding drive voltage or drive current is applied to the motor 42, thereby generating the desired rotational power. The drive pulley 43, which is rotationally driven by the motor 42, is connected to the rotor of the motor 42 via a gear mechanism or the like (not shown), and rotates in conjunction with it.
[0021] The power transmission unit 50 transmits the power generated by the door engine 40 to the door unit 10, driving the movable doors 11L, 11R to open and close. The power transmission unit 50 includes a power transmission belt 51, a driven pulley 52, and a connecting member 53. The power transmission belt 51 is an annular timing belt with many teeth formed on its inner circumferential surface, and is wound around the drive pulley 43 on the right side of FIG. 1 and around the driven pulley 52 on the left side of FIG. 1. In this state, the horizontal dimension of the power transmission belt 51 is equal to the horizontal distance between the drive pulley 43 and the driven pulley 52, and is also approximately the same as the horizontal dimension of the movable range of the movable doors 11L, 11R. When the drive pulley 43 is rotated by the motor 42, the driven pulley 52 rotates in conjunction with the rotation via the power transmission belt 51.
[0022] The connecting member 53 connects the movable doors 11L and 11R to the power transmission belt 51, respectively, to drive them to open and close. Here, one movable door is connected to the upper side of the power transmission belt 51, and the other movable door is connected to the lower side of the power transmission belt 51. In the example of FIG. 1, when the power transmission belt 51 rotates counterclockwise, the first movable door 11L moves to the left and the second movable door 11R moves to the right, which is an opening operation, and when the power transmission belt 51 rotates clockwise, the first movable door 11L moves to the right and the second movable door 11R moves to the left, which is a closing operation.
[0023] In the automatic door 100 configured as described above, when the activation sensor 31 detects a pedestrian, the door engine 40 generates counterclockwise rotational power under the control of the controller 20, thereby driving the door unit 10 to open. Furthermore, if a state in which no pedestrian is detected continues for a predetermined time after the opening drive, the door engine 40 generates clockwise rotational power under the control of the controller 20, thereby driving the door unit 10 to close. Furthermore, if the protection sensor 32 or the activation sensor 31 detects a pedestrian during the closing drive, the controller 20 performs reversal control to switch from the closing drive to the opening drive.
[0024] FIG. 2 shows a schematic diagram of various components that can communicate with each other inside and outside the automatic door 100. The automatic door 100 is equipped with a bus 2 to which each component is connected and which allows data communication between the components. The bus 2 is configured in accordance with any communication standard, for example, CAN (Controller Area Network). CAN is designed to allow components to communicate with each other without going through a host computer, and is widely used to transmit control information for various systems, not just automatic doors. Each component connected to the bus 2 can send information to other components via the bus 2, and can selectively receive information that it needs from the information sent to the bus 2 by other components.
[0025] FIG. 2 illustrates components connected to the bus 2, including the controller 20, activation sensor 31, touch plate 31A, protection sensor 32, operation panel 33, authentication device 34, electric lock controller 35, external interface 36, and display device 37. All of these components constitute the automatic door 100. Note that this diagram merely lists components that can be connected to the bus 2, and components not shown in FIG. 1 are also shown. Furthermore, the components to be included in the actual automatic door 100 can be selected according to the purpose, and not all of the components shown in the diagram are required. For example, an automatic door 100 that operates the door section 10 solely by detecting and operating a pedestrian does not require an operation panel 33 for operation by an attendant. Conversely, an automatic door 100 at a tourist facility or amusement park that operates the door section 10 solely by the operation of a facility attendant does not require an activation sensor 31 or touch plate 31A for detecting and operating a pedestrian. However, the controller 20 that controls the entire automatic door 100 is often an essential component.
[0026] Of the components shown in the figure, the controller 20, activation sensor 31, touch plate 31A, and protection sensor 32 have been described above, so their description will be omitted. The operation panel 33 is a control panel operated by facility staff at tourist facilities, amusement parks, etc., to drive the door unit 10. For example, in an attraction in which users move between different rooms at predetermined times, the staff operates the operation panel 33 in accordance with the movement timing to control the opening and closing of the door unit 10 of each room, allowing the users to move smoothly. The operation panel 33 may be fixedly installed in the facility or may be portable by the staff. Furthermore, the functions of the operation panel 33 may be realized in an information and communication device such as a tablet or smartphone that can communicate with the controller 20, etc., via an external interface 36, which will be described later.
[0027] The authentication device 34 authenticates passersby who should be allowed to pass through locations requiring a high level of security, such as the entrances to apartment buildings or offices. Authentication methods include password authentication via keypad entry on a keypad located near the door unit 10, and biometric authentication using the passerby's biometric information, such as a fingerprint. If authentication by the authentication device 34 is successful, the controller 20 drives the door unit 10 to open, allowing the passerby to pass through the automatic door 100. If authentication by the authentication device 34 fails, even if the activation sensor 31 detects the passerby, the controller 20 does not drive the door unit 10 to open, thereby preventing unauthorized passersby from passing through.
[0028] The electric lock controller 35 controls the electric lock 35A that locks the automatic door 100. The electric lock 35A includes, as lock driving means for driving the lock between a locked position and an unlocked position, a solenoid that generates a driving force according to the energized state, for example.
[0029] The external interface 36 exchanges signals with various external devices 36A external to the automatic door 100 via wired or wireless connections. Examples of the external device 36A include a work terminal such as an adjuster used by a worker who visits the site to install or maintain the automatic door 100, or a remote server or computer connected via a public information and communication network such as the Internet. The image control unit functions of this embodiment, which will be described later, may be implemented by the external device 36A external to the automatic door 100 or within the automatic door 100. When implementing the image control unit functions using the external device 36A, it is preferable to use a server or computer installed in a backroom in the same building as multiple automatic doors 100, where management and control of these doors is centralized. Input operations on the external device 36A allow various settings, such as control of each component of the automatic door 100 and parameter adjustment, to be performed. The external device 36A can also read information from each component of the automatic door 100 and its associated memory to diagnose the status and perform maintenance and inspection of the automatic door 100. As mentioned above, the bus 2 within the automatic door 100 is configured in accordance with the CAN standard, but if communication between the external device 36A and the external interface 36 is carried out using a different standard, such as Bluetooth (registered trademark) or Wi-Fi (registered trademark), the external interface 36 functions as a protocol converter that converts signals based on one standard into signals based on the other standard.
[0030] The display device 37 has a display unit that displays image signals received from other components and the external device 36A. The display device 37 may be installed, for example, near the automatic door 100 or in a back yard in the same building as the automatic door 100, and may be a display that displays the operating status of the automatic door 100. If this display device 37 has an input function such as a touch panel, various settings such as control of the components of the automatic door 100 and parameter adjustments can be made by touching the display. Furthermore, as will be described later, the display device 37 may be installed in the door section 10 of the automatic door 100, i.e., the movable doors 11L, 11R or the fixed doors 12L, 12R. In the following explanation, the display device 37 is assumed to be installed in the door section 10 unless otherwise specified.
[0031] The components of the automatic door 100 listed above, namely, the controller 20, activation sensor 31, touch plate 31A, protection sensor 32, operation panel 33, authentication device 34, electric lock controller 35, external interface 36, and display device 37, can communicate with each other via bus 2 conforming to the CAN standard. That is, each component has a built-in CAN transceiver and CAN controller for CAN communication. In addition, the external interface 36 has a protocol conversion unit that converts the protocol between the communication standard used by the external device 36A and the CAN standard. As a result, the external device 36A connected to the external interface 36 can communicate with the other components of the automatic door 100 via bus 2.
[0032] An overview of the automatic door 100 has been explained above with reference to Figures 1 and 2. Next, the configuration of the automatic door 100 in which the display device 37 is provided on the door section 10 will be explained. Figure 3 is an exploded perspective view of the automatic door 100 in which the display device 37 is provided on the door section 10. The display device 37 is provided on each of the four doors 12L, 11L, 11R, and 12R that make up the door section 10. Hereinafter, the doors 12L, 11L, 11R, and 12R may be collectively referred to as doors 10.
[0033] The display device 37 provided on the door 10 is composed of multiple rectangular display modules 70 that are elongated in the horizontal or left-right direction. In the illustrated example, the display device 37 of the door 10 is composed of eight display modules 70 that are arranged vertically or vertically without any gaps on the surface of the door 10. In this configuration, substantially the entire surface of the door 10 is covered by the multiple display modules 70. However, the display modules 70 or the display device 37 may be provided on only a portion of the surface of the door 10. For example, the display modules 70 may not be provided on the upper part of the door 10, prioritizing visibility on the opposite side of each door 10. However, as described below, the display modules 70 are transparent, so sufficient visibility on the opposite side of the door 10 can be ensured even if the display modules 70 are present. Furthermore, the lower part of the door 10 is likely to become dirty or scratched, and even if an image is displayed thereon, it is unlikely to be noticed by passersby. Therefore, the display modules 70 may not be provided on the lower part of the door 10. Note that the display modules 70 are not limited to being rectangular and may be any shape, and may be arranged with gaps between each display module 70.
[0034] In the illustrated example, where substantially the entire surface of the door 10 is covered by a plurality of display modules 70 arranged closely together, an image control unit (described later) synchronizes the images displayed on each display module 70, allowing the plurality of display modules 70 to display one large composite image on the surface of the door 10. In other words, the door 10 functions as if it were a single display. Furthermore, if an abnormality occurs in the image display of the display device 37, it is only necessary to repair or replace the defective display module 70, eliminating the need to repair or replace the entire display device 37, allowing for efficient maintenance.
[0035] Each display module 70 includes a display unit 71 that is provided on the surface of the door 10 and displays an image signal, and a connector unit 72 that is provided inside the vertical frame 14 of the door 10 and acquires the image signal. In other words, the display device 37 is composed of multiple pairs (display modules 70) of display units 71 and connector units 72. The display units 71 are preferably transparent and flexible. A transparent display unit 71 ensures visibility on the opposite side of the door 10, while a flexible display unit 71 improves ease of attachment to the surface of the door 10 and adhesion. A film-shaped LED (Light Emitting Diode) or OLED (Organic Light-Emitting Diode) can be used as the display unit 71 that combines transparency and flexibility.
[0036] Note that, although a portion of the display unit 71 may become opaque due to light-emitting elements and peripheral elements mounted on the display unit 71, as long as at least a portion of the display unit 71 is transparent or translucent when the display unit 71 is not displaying an image, visibility of the opposite side of the door 10 can be ensured, and therefore, in this embodiment, such a display unit 71 is also said to be translucent. Furthermore, the display unit 71 does not have to be translucent or flexible. For example, the display unit 71 may be made of a liquid crystal that is neither translucent nor flexible. In this case, by displaying an image of the opposite side of the door 10 on the display unit 71, visibility of the opposite side of the door 10 can be virtually ensured.
[0037] The connector unit 72 is provided adjacent to the display unit 71 at the horizontal or left-right end of the display module 70. The connector unit 72 is provided at the left end of the doors 12L and 11L on the left side of the figure, far from the opening of the door unit 10, while the connector unit 72 is provided at the right end of the doors 11R and 12R on the right side of the figure, far from the opening of the door unit 10. In each door 10, the connector units 72 of the multiple display modules 70 are aligned vertically or up-down at a position overlapping the vertical frame 14. A guide unit 141 is provided inside the vertical frame 14, through which wiring from each connector unit 72 runs along the longitudinal direction, i.e., the vertical direction. The wiring passing through the guide unit 141 connects each connector unit 72 of the display device 37 to the bus 2 in FIG. 2 . This allows each connector unit 72 to obtain an image signal from the bus 2 and display the image on the display unit 71. As described below, the image signal to be displayed on the display unit 71 is mainly supplied from an image control unit serving as the external device 36A. In this case, the image signal is transmitted through a path that goes from the image control unit (external device 36A), external interface 36, bus 2, guide unit 141 (wiring), connector unit 72, and display unit 71.
[0038] The vertical frame 14 of the door 10 is provided with a removable cover portion 142. The cover portion 142 is a member that is long in the vertical or up-down direction, and houses the connector portions 72 and guide portions 141 of multiple display modules 70 inside the vertical frame 14. FIG. 4 is a cross-sectional view of the door 10 as viewed from above. The vertical frame 14, which is substantially hollow inside, is provided with a vertical frame main body 143 to which the cover portion 142 is attached from the front (lower in FIG. 4). The vertical frame main body 143 and the cover portion 142 are engaged with each other by two engagement portions 144, 145. At the first engagement portion 144, the front surface of the vertical frame main body 143 abuts against the rear surface of the cover portion 142, and the left side surface of the vertical frame main body 143 abuts against the right side surface of a protrusion provided on the cover portion 142, and the two are engaged with each other. At the second engaging portion 145, two protrusions of the vertical frame main body 143 provided at the upper and lower ends of the vertical frame 14 are engaged with the cover portion 142 in a state where they come into contact with each other. The engaging portions 144, 145 may be engaged in any manner, but may be, for example, a snap fit method.
[0039] The connector portions 72 of the multiple display modules 70 are attached to a rectangular mounting surface 146 that is elongated in the vertical or up-down direction. In FIG. 4, the connector portions 72 appear to be divided into left and right halves by the second engagement portions 145, but as mentioned above, the second engagement portions 145 are provided only at the upper and lower ends of the vertical frame 14, and therefore the connector portions 72 installed between the upper and lower ends are connected to the left and right. The connector portions 72 are connected to a display unit 71 provided on the surface of the door 10 by wiring 73, and supply image signals to the display unit 71. When the cover portion 142 is removed, all of the connector portions 72 inside the vertical frame 14 are exposed to the outside, facing forward, allowing efficient maintenance work such as inspection, repair, and replacement of each display module 70.
[0040] The guide portion 141 is attached to a rectangular mounting surface 147 that is elongated in the vertical or up-down direction. While the mounting surface 146 of the connector portion 72 faces forward, the mounting surface 147 of the guide portion 141 faces sideways (toward the left in FIG. 4 ). In other words, the normal direction of the mounting surface 146 of the connector portion 72 and the normal direction of the mounting surface 147 of the guide portion 141 intersect, strictly speaking, perpendicularly. By orienting the mounting surface 147 of the guide portion 141 sideways, the internal space of the vertical frame 14 can be efficiently utilized to accommodate the guide portion 141, which occupies a larger volume than the connector portion 72. In addition, the mounting surfaces 146 and 147 are also the outer peripheral surfaces of the door gripping portion 148 that grips the door 10 with the vertical frame 14. In this way, the connector portion 72 and the guide portion 141 can be attached using the existing structure of the door gripping portion 148, making it easy to install the display device 37 on the door 10. As described above, the wires (not shown) from the connectors 72 pass through the guide portion 141 in the vertical direction (the direction perpendicular to the paper surface of FIG. 4).
[0041] In the illustrated example, the display module 70 consisting of the display unit 71 and the connector unit 72 is provided on the front surface of the door 10 (the bottom surface in Figure 4), but the display module 70 may also be provided on the rear surface of the door 10 (the top surface in Figure 4), or on both the front and rear surfaces of the door 10.
[0042] Next, we will explain image display by the display device 37 provided on the door section 10. Figure 5 is a functional block diagram of the image control device 80 of the automatic door 100. The image control device 80 includes an image control unit 81, a detection information acquisition unit 82, a selection unit 83, and a transmission information acquisition unit 84.
[0043] The image control unit 81 is configured as an external device 36A (FIG. 2) outside the automatic door 100, and provides image signals to each display module 70 via the external interface 36 and the bus 2. As indicated by "local" in FIG. 5, the function of the image control unit 81 is realized by a server or computer installed in a backroom of the same building as one or more automatic doors 100, which centrally manages and controls them. Note that the function of the image control unit 81 may also be realized as a component device within the automatic door 100, as shown in FIG. 2. The image control unit 81 receives image signals to be displayed on the display device 37 from an image server 90 installed remotely or locally in the same building. Then, based on various information provided by the detection information acquisition unit 82, the selection unit 83, and the transmission information acquisition unit 84, as described below, the image control unit 81 performs image control processing such as processing, adjustment, editing, modification, superimposition, and addition on the image signals received from the image server 90, and transmits the processed images to each display module 70.
[0044] In this way, the image server 90 and the image control unit 81 each generate an image signal. There are no restrictions on the type or content of the image signal each generates, but typically, the image server 90 generates image signals that are not dependent on the situation around the automatic door 100, such as advertisements and general information that should be disseminated to people passing by the automatic door 100, while the image control unit 81 generates additional image signals that are dependent on the situation around the automatic door 100, such as warning information, passage assistance information, opening position information, and cautionary area information, which will be described later. Note that if the image server 90 and image control unit 81 are installed in the same location, they do not need to be configured as separate entities but can be configured as an integrated unit.
[0045] The detection information acquisition unit 82 acquires detection information from sensors that detect the situation around the automatic door 100. The type, number, and installation manner of the sensors are not important, but various sensors can be used, such as the activation sensor 31 (including the touch plate 31A in FIGS. 1 and 2), the protection sensor 32, the door operation detection unit 821, the image sensor 822, and the brightness sensor 823, as exemplified in FIG. 5. Although not shown, if these sensors are installed outside the automatic door 100, the detection information acquisition unit 82 acquires the detection information via the external interface 36 and the bus 2. For example, detection information from the image sensor 822 of a surveillance camera outside the automatic door 100 that captures images around the automatic door 100 is provided to the detection information acquisition unit 82 from the surveillance camera as an external device 36A (FIG. 2) via the external interface 36 and the bus 2. The image control unit 81 controls the image displayed by the display unit 71 or the display device 37 installed on the door 10 of the automatic door 100 based on the detection information acquired by the detection information acquisition unit 82.
[0046] The detection information of the activation sensor 31 indicates the detection state of the activation sensor 31. That is, in the detection state, when a detection target, such as a person passing by the automatic door 100, is within the detection area of the activation sensor 31, the detection information is generated in response to a significant change in the amount of light received by the light-receiving element of the activation sensor 31 due to the detection target blocking the light. On the other hand, in the non-detection state, when the detection target is not within the detection area of the activation sensor 31, no detection information is generated because there is no significant change in the amount of light received by the light-receiving element of the activation sensor 31. As will be described later, when the image control unit 81 determines that the activation sensor 31 is in the detection state based on the detection information, it performs at least one of the following controls: hiding the image displayed on the display unit 71 or the display device 37; reducing the size of the image; moving the image toward the edge of the display unit 71 or the display device 37; or displaying an image of the opposite side of the door unit 10.
[0047] According to the detection information of the activation sensor 31, it is also possible to detect that the object being detected by the activation sensor 31 is moving toward the door section 10. That is, since the activation sensor 31 is equipped with a plurality of light receiving units that receive reflected light from a plurality of detection spots obtained by dividing the floor surface as a detection area into a grid pattern or the like, if the detection spot at which the object is detected is moving toward the door section 10, it is known that the object is moving toward the door section 10. As will be described later, when the image control unit 81 determines, based on the detection information, that the object being detected by the activation sensor 31 is moving toward the door section 10, it performs at least one of the following controls: hiding the image displayed on the display unit 71 or the display device 37; reducing the size of the image; moving the image toward the edge of the display unit 71 or the display device 37; or displaying an image of the opposite side of the door section 10.
[0048] Similarly, the detection information from the activation sensor 31 can detect an approaching person approaching the door section 10. As will be described later, when the image control section 81 determines based on the detection information that there is an approaching person approaching the door section 10, it changes the image displayed by the display section 71 or the display device 37 in relation to the detected approaching person.
[0049] The detection information from the activation sensor 31 can be used to configure a congestion estimation unit that estimates the congestion level around the automatic door 100. In other words, if a large number of detection spots detect the detection target, it can be determined that the detection area is crowded with many detection targets. However, because the detection area of the activation sensor 31 is limited, it is preferable to use the image sensor 822 and transmission information acquisition unit 84 (described below) to estimate the congestion level over a larger area. As described below, the image control unit 81 changes the image displayed by the display unit 71 or the display device 37 depending on the congestion level around the automatic door 100 estimated based on the detection information. Furthermore, when the congestion level estimated by the congestion level estimation unit is equal to or lower than a threshold, the image control unit 81 may hide the image on the display unit 71 or the display device 37 or may reduce the brightness of the image on the display unit 71 or the display device 37.
[0050] The detection information from the activation sensor 31 can also detect abnormalities in people around the automatic door 100. For example, if a detection target (person) is detected at the detection spot of the activation sensor 31 adjacent to the fixed doors 12L and 12R, which people should not approach, it can be recognized that this is an abnormal state in which the opening movable doors 11L and 11R may collide with the detection target (person). However, because the detection area of the activation sensor 31 is limited, it is preferable to use the image sensor 822 and transmission information acquisition unit 84, described below, to detect abnormalities over a wider area. As described below, when the image control unit 81 detects an abnormality in a person around the automatic door 100 based on the detection information, it displays warning information on the display unit 71 or the display device 37 to alert the person about the abnormality.
[0051] The detection information from the activation sensor 31 can also detect the operation of the movable doors 11L and 11R. That is, when the detection information from the activation sensor 31 is input to the controller 20, the door engine 40 is driven to open the movable doors 11L and 11R, and the detection information from the activation sensor 31 indicates the opening operation of the movable doors 11L and 11R. Furthermore, because the speed and opening width of the opening operation of the movable doors 11L and 11R are preset by the controller 20, the position and speed of the movable doors 11L and 11R during the opening operation can also be detected. Furthermore, because the timing at which the movable doors 11L and 11R, which are in the fully open position, start the closing operation and the speed of the closing operation are also preset by the controller 20, the position and speed of the movable doors 11L and 11R during the closing operation can also be detected. In this way, the detection information from the activation sensor 31 serves as a trigger to detect the opening and closing operations of the movable doors 11L and 11R. In addition, if the door operation detection unit 821 is provided with a position sensor or a speed sensor that measures the position and speed of the movable doors 11L, 11R, the operation of the movable doors 11L, 11R may be detected based on the detection information. As will be described later, the image control unit 81 controls the image displayed by the display unit 71 or the display device 37 in accordance with the operation of the movable doors 11L, 11R detected based on the detection information.
[0052] The detection information of the protection sensor 32 indicates the detection state of the protection sensor 32. That is, in the detection state where a detection target, such as a person passing through the automatic door 100, is within the detection area of the protection sensor 32, the detection information is generated in response to a significant change in the amount of light received by the light-receiving unit of the protection sensor 32 due to the detection target blocking the light. On the other hand, in the non-detection state where the detection target is not within the detection area of the protection sensor 32, no detection information is generated because there is no significant change in the amount of light received by the light-receiving unit of the protection sensor 32. As will be described later, when the image control unit 81 determines that the protection sensor 32 is in the detection state based on the detection information, it causes the display unit 71 or the display device 37 to display attention-calling information.
[0053] According to the detection information of the protection sensor 32, the operation of the movable doors 11L, 11R can also be detected in addition to the detection information of the activation sensor 31. That is, when the protection sensor 32 detects a person passing by while the movable doors 11L, 11R are closing, the controller 20 performs reversal control to stop the closing drive and switch to the opening drive, and therefore the detection information of the protection sensor 32 indicates the reversal operation of the movable doors 11L, 11R. Furthermore, because the speed and opening width of the reversal operation of the movable doors 11L, 11R are preset by the controller 20, the position and speed of the movable doors 11L, 11R during the reversal operation can also be detected.
[0054] The image sensor 822 provides the detection information acquisition unit 82 with image information captured around the automatic door 100 as detection information. The image sensor 822 may be installed on the automatic door 100 or on a security camera or other device outside the automatic door 100. Similar to the detection information from the activation sensor 31, the detection information from the image sensor 822 can detect the movement of a detection target toward the door section 10, a person approaching the door section 10, the congestion around the automatic door 100, abnormalities in people around the automatic door 100, and the operation of the movable doors 11L and 11R. In this case, by utilizing image recognition and image analysis technologies based on artificial intelligence and machine learning, it is possible to individually recognize people and objects as detection targets and grasp each person's behavior, facial expression, line of sight, clothing, attributes such as age and gender, status, and circumstances. As described below, the image control unit 81 displays images and information aimed at people around the automatic door 100 on the display unit 71 or the display device 37 based on the detection information from the image sensor 822. For example, the image control unit 81 changes the image in the line of sight of a person approaching the door unit 10 based on the detection information of the image sensor 822.
[0055] The luminance sensor 823 measures the luminance around the automatic door 100 and provides the luminance information to the detection information acquisition unit 82 as detection information. The luminance sensor 823 may be provided on the automatic door 100 itself, or on a wall or ceiling outside the automatic door 100. The image control unit 81 adjusts the luminance of the image displayed by the display unit 71 or the display device 37 according to the detection information from the luminance sensor 823. That is, if the luminance around the automatic door 100 is high, the luminance of the image is increased, and if the luminance around the automatic door 100 is low, the luminance of the image is decreased, thereby adjusting the image so that people around the automatic door 100 can properly see it. Note that, because the change in luminance over the course of a day is somewhat determined by the season, the luminance of the image may be adjusted according to the passage of time throughout the day without using the luminance sensor 823.
[0056] The selection unit 83 selects at least one person near the automatic door 100 based on the detection information acquired by the detection information acquisition unit 82, particularly the detection information from the image sensor 822. For example, the selection unit 83 selects a person whose line of sight is covered by the display unit 71 or the display device 37. The image control unit 81 displays an image directed at the person selected by the selection unit 83 on the display unit 71 or the display device 37. As described above, the detection information from the image sensor 822 can be used to ascertain the behavior, facial expression, line of sight, clothing, attributes such as age and gender, status, and situation of the person selected by the selection unit 83. Therefore, the image control unit 81 can select from the image server 90 images or information that are likely to interest the person and display them on the display unit 71 or the display device 37.
[0057] The transmitted information acquisition unit 84 acquires transmitted information from an information communication device 84A located near the automatic door 100. The transmitted information acquired by the transmitted information acquisition unit 84 is limited to information transmitted to the image control device 80 by an information communication device 84A, such as a mobile phone, smartphone, tablet, or personal computer, used by a user near the automatic door 100, or information that the user has authorized the image control device 80 to acquire. The image control unit 81 controls the image displayed by the display unit 71 or the display device 37 based on the transmitted information acquired by the transmitted information acquisition unit 84. For example, if the transmitted information acquired by the transmitted information acquisition unit 84 includes information on the user's behavior, preferences, attributes such as age and gender, status, and situation, the image control unit 81 can select images or information that are likely to interest the user from the image server 90 and display them on the display unit 71 or the display device 37. Furthermore, the transmitted information acquired by the transmitted information acquisition unit 84 may be used to detect the congestion level around the automatic door 100 or abnormalities in the presence of people near the automatic door 100, similar to the detection information from the activation sensor 31 and the image sensor 822. For example, if the transmitted information acquisition unit 84 acquires transmitted information from many information communication devices 84A in a short period of time, it can be seen that the area around the automatic door 100 is crowded with many users of the information communication devices 84A.
[0058] Next, a specific example of an image displayed on the display device 37 provided on the door section 10 will be described. Fig. 6 schematically shows the situation around the automatic door 100 and images I2L, I1L, I1R, and I2R displayed on the display device 37 provided on each of the doors 12L, 11L, 11R, and 12R of the door section 10. There are many people around the automatic door 100, and a first person P1 has entered the detection area 31B of the activation sensor 31 and is approaching the automatic door 100 to pass through, with his line of sight S1 directed toward the advertising image I1L displayed on the movable door 11L, and a second person P2 has his line of sight S2 directed toward the advertising image I1R displayed on the movable door 11R. The situation and behavior of people around the automatic door 100 are detected by the image sensor 822, etc., including the fact that a first person P1 is looking at the advertising image I1L on the movable door 11L while moving towards the automatic door 100, and the fact that a second person P2 is looking at the advertising image I1R on the movable door 11R. In the illustrated example, in addition to the image sensor 822 and brightness sensor 823, an environmental sensor 824 is provided as a sensor outside the automatic door 100 to measure environmental data such as temperature, humidity, and noise around the automatic door 100, and is used for image control by the image control unit 81. For example, when the temperature is high, the image control unit 81 displays advertising images for cold drinks or ice cream on the door 10.
[0059] FIG. 7 shows an example of an image displayed for a first person P1. In FIG. 7(A), an image similar to that in FIG. 6 is displayed on each of the doors 12L, 11L, 11R, and 12R. As mentioned above, the first person P1 is looking at the advertising image on the movable door 11L, and the center of his field of view or visual field is indicated by S1. FIGS. 7(B) to 7(J) show example images of the movable door 11L that are changed by the image control unit 81 for the first person P1 as an approacher approaching the movable doors 11L and 11R. Although only an example image of the movable door 11L is shown here, the image control unit 81 may also change the image of the movable door 11R in a similar manner.
[0060] In FIG. 7(B), the image control unit 81 hides the image of the movable door 11L in response to the activation sensor 31 being activated by the first person P1 in the detection area 31B. At this time, instead of the hidden image, highly visible information such as text information that does not obstruct the view of the first person P1 may be displayed on the movable door 11L. In FIG. 7(C), the image control unit 81 reduces the brightness of the image of the movable door 11L in response to the activation sensor 31 being activated by the first person P1 in the detection area 31B. In FIG. 7(D), the image control unit 81 reduces the image of the movable door 11L in response to the activation sensor 31 being activated by the first person P1 in the detection area 31B. In FIG. 7(E), the image control unit 81 moves the image of the movable door 11L toward the edge of the movable door 11L in response to the activation sensor 31 being activated by the first person P1 in the detection area 31B. These image examples prevent the field of view of the first person P1 about to pass through the automatic door 100 from being obstructed by advertising images, etc., thereby increasing safety while passing through. Note that the images in Figures 7(B) to (E) above and the images in Figures 7(F) to (J) described below may be displayed by the image control unit 81 when the detection information acquisition unit 82 detects that the first person P1 in the detection area 31B is moving toward the movable doors 11L, 11R.
[0061] In the examples of Figures 7(F) to (I), the image control unit 81 changes the image within the field of view S1 or line of sight S1 of the first person P1, who is an approaching individual. In Figure 7(F), the image control unit 81 hides the image within the field of view S1 or line of sight S1 of the first person P1. In Figure 7(G), the image control unit 81 lowers the brightness of the image within the field of view S1 or line of sight S1 of the first person P1. In this case, the brightness of the image within the field of view S1 or line of sight S1 may be gradually lowered as the first person P1 approaches the movable door 11L. In this way, the first person P1 can safely pass through the automatic door 100 without being dazzled by the image of the movable door 11L. In Figure 7(H), the image control unit 81 moves the image outside the field of view S1 or line of sight S1 of the first person P1. In Figure 7(I), the image control unit 81 displays an image of the opposite side of the movable door 11L within the field of view S1 or line of sight S1 of the first person P1. These image examples can prevent the field of view S1 of the first person P1 who is about to pass through the automatic door 100 from being obstructed by advertising images or the like, thereby improving safety while passing through.
[0062] In FIG. 7(J), the image control unit 81 displays passage assistance information on the movable door 11L as a display unit to assist the first person P1, who is an approaching person, in passing through the automatic door 100. Specifically, opening position information 811 indicating the position of the opening of the automatic door 100 and caution area information 812 indicating caution areas such as the opening and closing sections of the automatic door 100 and the mullions are displayed on the movable door 11L as passage assistance information. When the movable door 11L and the other doors 12L, 11R, and 12R are used as displays for advertising images, etc., as in FIG. 7(A), attention to the actual opening and closing operation of the automatic door 100 may be reduced. However, by displaying passage assistance information to a person approaching the automatic door 100 as in FIG. 7(J), attention to the opening and closing operation can be drawn, thereby increasing safety during passage. While the image examples in FIGS. 7(B) to 7(J) have been described individually above, these image examples may also be combined as appropriate. For example, the brightness of the image may be lowered as in FIG. 7(C) or the image may be reduced as in FIG. 7(D), and at the same time, traffic aid information as in FIG. 7(J) may be displayed.
[0063] FIG. 8 shows an example of an image displayed to a second person P2. In FIG. 8(A), an image similar to that shown in FIG. 6 is displayed on each of the doors 12L, 11L, 11R, and 12R. As mentioned above, the second person P2 is looking at the advertising image for the movable door 11R, and the center of his or her field of view is indicated by S2. FIG. 8(B) shows an example of an image of the movable door 11R displayed by the image control unit 81 to the second person P2 looking at the advertising image. By displaying special discount information on the advertising image that the second person P2 is looking at, the second person P2's desire to purchase a product can be encouraged. Note that this image display is performed via the selection unit 83 mentioned above. The selection unit 83 selects the second person P2 whose line of sight S2 is the movable door 11R (display device 37) based on the detection information acquired by the detection information acquisition unit 82, particularly the detection information from the image sensor 822. Then, the image control unit 81 causes the image of FIG. 8(B) directed at the second person P2 selected by the selection unit 83 to be displayed on the movable door 11R.
[0064] 9 shows an example in which the image control unit 81, having detected an abnormality in a person near the automatic door 100 based on the detection information acquired by the detection information acquisition unit 82, displays warning information on each of the doors 12L, 11L, 11R, and 12R to alert the person about the abnormality. A third person P3 has entered the detection area 31B of the activation sensor 31 and is running at high speed toward the automatic door 100, and there is a possibility that he will collide with the movable doors 11L and 11R before they open. Therefore, the image control unit 81 detects the abnormality and displays warning information 813 on both movable doors 11L and 11R to urge the third person P3 to stop. Since the fourth person P4 is in contact with or close to the fixed door 12L within the detection area 31B of the activation sensor 31 and there is a possibility of a collision if the movable door 11L opens, the image control unit 81 detects the abnormality and causes the fixed door 12L to display warning information 814 warning the fourth person P4 not to stand in front of the fixed door 12L. Note that since there is no warning information to be displayed on the fixed door 12R, an advertising image or the like may be displayed as is.
[0065] FIG. 10 shows example images that the image control unit 81 displays on each of the doors 12L, 11L, 11R, and 12R in response to the operation of the movable doors 11L, 11R detected based on the detection information acquired by the detection information acquisition unit 82. In FIG. 10(A), the same image as in FIG. 6 is displayed on each of the doors 12L, 11L, 11R, and 12R. FIG. 10(B) shows example images of the movable doors 11L and 11R during their opening operation. In this example, the image in FIG. 10(A) appears to be displayed as is, but the image of the fixed door 12L, which is hidden by the movable door 11L, is hidden where the movable door 11L and the fixed door 12L overlap, and the image of the fixed door 12R, which is hidden by the movable door 11R, is hidden where the movable door 11R and the fixed door 12R overlap. By hiding the image of the portion that cannot be seen from outside in this way, power consumption of the display devices 37 of the fixed doors 12L and 12R can be reduced.
[0066] Instead of Figure 10(B), as shown in Figure 10(C), the size, orientation, position, speed, etc. of the advertised products in the image may be dynamically changed to match the screen of the fixed doors 12L, 12R, which gradually become smaller as the movable doors 11L, 11R open, as in Figure 10(C). In this way, by dynamically changing the image according to the movement of the movable doors 11L, 11R, i.e., their position and speed, it is possible to attract the attention of people around the automatic door 100.
[0067] FIG. 10(D) shows the fully open state, with the movable doors 11L and 11R overlapping the fixed doors 12L and 12R, respectively. At this timing, the images of the doors 12L, 11L, 11R, and 12R are reset. In FIG. 10(E), as the movable doors 11L and 11R close, images different from those shown in FIGS. 10(A) to 10(C) gradually appear on the doors 12L, 11L, 11R, and 12R. As in FIG. 10(C), the size, orientation, position, speed, and the like of the advertised products and the like in the images dynamically change in accordance with the screen of the fixed doors 12L and 12R, which gradually increases in size in accordance with the closing movement of the movable doors 11L and 11R. Furthermore, the image control unit 81 controls the images of the movable doors 11L and 11R so that the advertised products and the like in the images gradually approach from the rear to the front in accordance with the position and speed of the closing movement of the movable doors 11L and 11R.
[0068] FIG. 10(F) shows the fully closed state. As mentioned above, an image different from that shown in FIG. 10(A), which shows the previous fully closed state, is displayed on each of the doors 12L, 11L, 11R, and 12R. In this way, by changing the image each time the movable doors 11L and 11R are opened and closed, it is possible to keep the interest of people around the automatic door 100. As another example of changing the image each time the movable doors 11L and 11R are opened and closed, the people and objects displayed on each of the doors 12L, 11L, 11R, and 12R may move slightly each time the movable doors 11L and 11R are opened and closed. In this case, the automatic door 100 functions like a flip book or a picture-story show, where people and objects move each time the doors are opened and closed.
[0069] If the image control unit 81 detects an exceptional operation that differs from the normal operation of the movable doors 11L and 11R based on the detection information acquired by the detection information acquisition unit 82, the image control unit 81 may display explanatory information and / or warning information on each of the doors 12L, 11L, 11R, and 12R. For example, if the protective sensor 32 detects a passerby while the movable doors 11L and 11R are closing and a reversal operation occurs in which the closing operation switches to an opening operation, the explanatory information and / or warning information may be displayed on at least one of the doors 12L, 12R. Also, when a fourth person P4 is in contact with or close to the fixed door 12L as shown in FIG. 9 , the opening operation of the movable doors 11L and 11R may be prohibited for safety reasons. If the explanatory information and / or warning information is displayed on the fixed door 12R, for example, people in the vicinity of the automatic door 100 can understand why the movable doors 11L and 11R will not open.
[0070] The image control unit 81 may change the image displayed by the door 10 depending on the congestion level around the automatic door 100 estimated based on the detection information acquired by the detection information acquisition unit 82. For example, the image control unit 81 switches between displaying and hiding the image of the door 10 depending on the estimated congestion level. Specifically, when the area around the automatic door 100 is crowded, an advertising image or the like is displayed on the door 10 to attract more people to view it, whereas when the area around the automatic door 100 is not crowded, even if an advertising image or the like is displayed, few people will view it, and therefore the image of the door 10 is hidden to reduce power consumption. The image control unit 81 may also change the brightness of the image of the door 10 depending on the estimated congestion level. For example, the brightness of the image of the door 10 is increased when the area is crowded, and decreased when the area is not crowded to reduce power consumption.
