[0014] Hereinafter, the present invention will be described with reference to the drawings based on preferred embodiments. In the embodiments and variations, the same or equivalent components and members are denoted by the same reference numerals, and redundant explanations will be omitted as appropriate. Also, the dimensions of the members in each drawing are enlarged or reduced as appropriate for ease of understanding. In addition, some of the members that are not important for explaining the embodiments in each drawing are omitted from the display.

[0015] Also, separate components with common points are distinguished by attaching "first", "second", etc. at the beginning of their names, and these are omitted when collectively referred to. Also, terms including ordinal numbers such as first and second are used to describe various components, but this term is used only for the purpose of distinguishing one component from another, and the components are not limited by this term.

[0016] First Embodiment FIG. 1 is a front view schematically showing an automatic door device 100. The automatic door device 100 shown in FIG. 1 is of a double-swing door type, and two doors 9 open and close automatically to the left and right. The doors 9 are a pair on the left and right, and are configured to be reciprocally movable along a fix ②② provided at intervals to the left and right with an opening 23 interposed therebetween, and open and close the opening 23. As an example, the automatic door device 100 is a device that opens and closes a door for opening and closing an opening 23 provided in a wall or the like that partitions a space in various facilities such as condominiums, hotels, and laboratories. The automatic door device 100 of the present embodiment is provided at the entrance and exit of a condominium.

[0017] It should be noted that there seems to be an error in the original text where "fix ②②" is mentioned. It should probably be "fix 22" for better understanding. The translation is adjusted based on the corrected understanding.Hereinafter, the direction along the opening and closing direction of the automatic door device 100 is referred to as the left-right direction. When the automatic door device 100 is viewed from the front as shown in FIG. 1, the left side is referred to as "left" and "leftward", and the right side is referred to as "right" and "rightward". Also, the direction along the prospective direction of the automatic door device 100 is referred to as the front-back direction. The side away from the automatic door device 100 is referred to as "front" and "frontward", and the side approaching the automatic door device 100 in the front-back direction is referred to as "rear" and "rearward". Further, the finding direction of the automatic door device 100 is referred to as the "up-down direction". Such direction notations do not limit the posture of the automatic door device 100, and the automatic door device 100 can be used in any posture.

[0018] The door 9 comes into contact such that the leading ends on the left and right abut against each other, and the opening 23 is closed to be in the fully closed state. The door 9 moves so that the leading ends separate, and moves and stops until the leading ends reach the vicinity of the end on the opening 23 side of the fixture 22, and the opening 23 is opened to be in the fully open state. Note that the automatic door device 100 may be of a double-swing door type, a single-swing door type, a folding door type, or the like.

[0019] FIG. 2 is a block diagram schematically showing the system configuration of the automatic door device 100 according to the first embodiment.

[0020] As shown in FIG. 2, the automatic door device 100 includes an automatic door sensor 10, a notification device 40, and an automatic door drive device 90 that opens and closes the door 9. The automatic door device 100 is configured to be communicable with an authentication device 51 and an opening permission device 52 of a security release system 50 provided outside the automatic door device 100.

[0021] The automatic door sensor 10 detects a person or an object (hereinafter sometimes referred to as a "detection target") within the activation detection area 70 and the protection detection area 71 of the automatic door device 100. The automatic door sensor 10 includes an outdoor activation sensor 4A and an indoor activation sensor 4B, and an auxiliary photoelectric sensor 30.

[0022] The outdoor activation sensor 4A detects the object in the outdoor activation detection area 70A, which is located around the outdoor side of the opening 23. The outdoor activation sensor 4A also detects the object in the protective detection area 71, which is located to protect the object from contact with the door 9 when the door 9 is in the opening operation. The outdoor activation sensor 4A is located, for example, in the center of the left-right direction on the outdoor side of the transom 16 above the opening 23.

[0023] The indoor activation sensor 4B detects the target object in the indoor activation detection area 70B, which is located around the indoor side of the opening 23. The indoor activation sensor 4B is positioned, for example, in the center of the left-right direction on the indoor side outer surface of the transom 16 above the opening 23.

[0024] Figure 3 is a schematic diagram showing the activation detection area 70 and protection detection area 71 of the first embodiment as viewed from above, and shows the activation detection area 70 and protection detection area 71 on the floor surface. As shown in Figure 3, the outdoor activation detection area 70A is provided on the outdoor side of the fully closed door 9. The indoor activation detection area 70B is provided on the opposite side of the opening 23 from the outdoor activation detection area 70A. In Figure 3, the solid line represents the fully closed door 9, and the dotted line represents the fully open door 9.

[0025] The protective detection area 71 includes a first protective detection area 71A and a second protective detection area 71B. The first protective detection area 71A is provided within the range of the opening width of the opening 23 (see Figure 3). In this embodiment, the first protective detection area 71A is provided between the left and right fixes 22 and is located on the opening 23 side from the track of the door 9. In addition, in this embodiment, the first protective detection area 71A is provided along the door surface of the door 9 on the fixe 22 side with respect to the door 9 in the depth direction. The first protective detection area 71A may or may not include the area on the track of the door 9.

[0026] The second protective detection area 71B is located on the tail end side of the door 9. The second protective detection area 71B is located outside the opening width of the opening 23 and on the front side of the fix 22 on the door 9 side. The second protective detection area 71B may or may not include the area on the track of the door 9.

[0027] The outdoor activation sensor 4A and the indoor activation sensor 4B are infrared reflection type sensors that emit and receive infrared light diagonally downward from their position on the transom 16, and detect objects entering the door 9. When the outdoor activation sensor 4A detects an object, it transmits an outdoor activation signal to the door controller 91. When the indoor activation sensor 4B detects an object, it transmits an indoor activation signal to the door controller 91. Hereinafter, the outdoor activation sensor 4A and the indoor activation sensor 4B may be collectively referred to as activation sensor 4. Also, the outdoor activation signal and the indoor activation signal may be collectively referred to as activation signal. The outdoor activation detection area 70A and the indoor activation detection area 70B constitute the activation detection area 70 of the automatic door device 100.

[0028] In this embodiment, the outdoor activation sensor 4A sequentially acquires the amount of infrared light received in the outdoor activation detection area 70A. The indoor activation sensor 4B sequentially acquires the amount of infrared light received in the indoor activation detection area 70B. For example, the outdoor activation sensor 4A and the indoor activation sensor 4B each determine the presence or absence of a detection target in their respective areas based on the acquired amount of light received. For example, the outdoor activation sensor 4A and the indoor activation sensor 4B each determine that a detection target exists in the activation detection areas 70A and 70B when the detection level of the amount of light received in their respective activation detection areas 70A and 70B exceeds a predetermined level, and generate an activation signal. Hereinafter, the state in which a detection target is determined to exist in the activation detection area 70 is referred to as the detection state, and the state in which there is no detection state is referred to as the non-detection state. Also, for example, the outdoor activation sensor 4A determines that a detection target exists in the protection detection area 71 when the detection level of the amount of light received in the protection detection area 71 exceeds a predetermined level, and generates a protection detection signal. The shapes of the activation detection area 70 and the protection detection area 71 may be circular, elliptical, rectangular, or polygonal in any way other than a rectangle. The number and size of the activation detection area 70 and the protection detection area 71 are not limited to the example in Figure 3 and may be set arbitrarily.

[0029] The auxiliary photoelectric sensor 30 is a photoelectric detection device and has a light emitter 301 and a light receiver 302 positioned near the opening 23 of the fixed 22. The auxiliary photoelectric sensor 30 detects when the light rays passing between the light emitter 301 and the light receiver 302 are blocked and transmits detection information to the door controller 91 indicating that a person or object is present in the track of the door 9. In addition to the photoelectric method, the auxiliary photoelectric sensor 30 may also be a light reflection method or an ultrasonic method detection device attached to the transom 16.

[0030] The automatic door drive unit 90 includes a door controller 91 and a door engine 92. The door controller 91 controls the door engine 92 to open and close the door 9 based on a start signal, detection information, and a security release signal described later. There are no limitations on the transmission path 96 that transmits the start signal, detection information, and security release signal described later, but in this example the transmission path 96 includes an internal bus (e.g., CAN: Controller Area Network). The door engine 92 drives the door 9 to open and close by rotating a motor (not shown) based on the control of the door controller 91.

[0031] When the door controller 91 receives an indoor activation signal, it activates the motor (not shown) of the door engine 92 to open the door 9 until it is fully open. On the other hand, in this embodiment, from the viewpoint of improving security inside the building by suppressing, for example, the entry of intruders from outside, the door controller 91 does not open the door 9 even if it receives an outdoor activation signal when it has not received the security release signal described later, but it opens the door 9 until it is fully open when it receives the outdoor activation signal while it has received the security release signal described later.

[0032] The door controller 91 maintains the fully open state for a certain period of time after the door 9 has changed to the fully open state, and then operates the door engine 92 in the reverse direction to drive the door 9 until it is fully closed. When the door controller 91 receives detection information from the auxiliary photoelectric sensor 30 while the door 9 is being driven to close, it reverses the direction in which the door engine 92 drives the door 9, bringing the door 9 back to the fully open state.

[0033] If the door controller 91 receives a restriction signal from the restriction unit 103 (described later) and an open instruction signal is output from the open instruction signal output unit 102 (described later), the door controller 91 will not open the door 9.

[0034] The security release system 50 includes an authentication device 51, an opening permission device 52, an external intercom 53 installed near the automatic door device 100, and an internal intercom 54 installed in the rooms of residents or managers of the apartment building. The authentication device 51 and the opening permission device 52 each output an authentication signal and an opening permission signal to the door controller 91 to release the security of the automatic door device 100 in order to allow a person (passerby) to pass through the opening 23 in a predetermined case. For example, when the door controller 91 receives an authentication signal or an opening permission signal, it remains in a state of having received a security release signal for a predetermined time. The authentication device 51 and the opening permission device 52 in this embodiment are each examples of security release devices. Also, the authentication signal of the authentication device 51 and the opening permission signal of the opening permission device 52 in this embodiment are each examples of security release signals. Hereinafter, the authentication signal and the opening permission signal may be collectively referred to as security release signals.

[0035] The authentication device 51 outputs an authentication signal based on the authentication of the passerby. The authentication device 51 is installed, for example, near the door 9. In this embodiment, the authentication device 51 is installed outdoors of the building where the automatic door device 100 is installed. The authentication device 51 may be, for example, a key operation device that authenticates passersby based on the operation of a predetermined key, a PIN input device for entering a PIN, or a biometric authentication device.

[0036] The access control device 52 outputs an access control signal based on input from a user (such as a resident or manager) inside the room. In this embodiment, the access control device 52 is installed in each room. For example, when a passerby communicates with a user inside the room by having the external intercom 53 and the internal intercom 54 communicate, the access control device 52 outputs an access control signal in response to receiving user input during the communication to permit the passerby to pass.

[0037] The notification device 40 is, for example, a speaker, an LED lamp, or a liquid crystal display. The notification device 40 can notify that the door 9 cannot be opened through the sound of the speaker, the flashing of the LED lamp, the display on the liquid crystal display, etc. In this embodiment, the notification device 40 is installed, for example, on the door surface of the door 9 or in the vicinity of the door 9, but it may also be installed outside the automatic door device 100. Alternatively, the notification device 40 may be, for example, a portable communication terminal owned by a passerby, resident, or caretaker.

[0038] Figure 4 is a functional block diagram of the door controller 91 of the first embodiment. Each block shown in the following figures can be realized in hardware terms by components such as a computer processor, CPU, and memory, as well as electronic circuits and mechanical devices, and in software terms by computer programs, etc., but here we are depicting functional blocks that are realized through the cooperation of these components. Therefore, it will be understood by those skilled in the art that these functional blocks can be realized in various ways by combinations of hardware and software.

[0039] As shown in Figure 4, the door controller 91 includes an acquisition unit 101, an open instruction signal output unit 102, a limiting unit 103, a control unit 104, and a notification unit 105.

[0040] The acquisition unit 101 acquires the activation signals and protection detection signals from the outdoor activation sensor 4A and the indoor activation sensor 4B, detection information from the auxiliary photoelectric sensor 30, and security release signals, etc.

[0041] The open instruction signal output unit 102 outputs an open instruction signal for the door 9 in predetermined cases. The automatic door device 100 in this embodiment is set so that the activation sensor 4 becomes active when a security release signal is received, and the open instruction signal output unit 102 outputs an open instruction signal when the activation signal for the activation sensor 4 is output.

[0042] The limiting unit 103 outputs a limiting signal to restrict the opening operation of the door 9 under predetermined conditions. In this embodiment, the limiting unit 103 outputs a limiting signal to restrict the opening operation of the door 9 when the outdoor activation sensor 4A detects a target in the protection detection area 71.

[0043] The control unit 104 controls the opening and closing operations of the door 9. The control unit 104 opens the door 9 based on the open instruction signal, and does not open the door 9 if the open instruction signal is output while a restriction signal has been received. Hereinafter, the operation of the door 9 when the opening operation is restricted may be referred to as the open protection operation.

[0044] In this embodiment, when the limiting unit 103 receives a protection detection signal while the door 9 is in a fully closed state, it outputs a limiting signal to prevent the door 9 from opening, and the control unit 104 performs an open protection operation for the door 9. On the other hand, when the protection detection signal is received while the door is in a state other than fully closed, the limiting unit 103 does not output a limiting signal, and the control unit 104 performs a predetermined closing protection operation for the door 9 (for example, closing at a slower speed than normal, stopping, or reversing to an open operation) to protect the detected object from the closing operation of the door 9.

[0045] Figure 5 is a flowchart showing the process S100 of the door controller 91 in the first embodiment.

[0046] In step S101, the open instruction signal output unit 102 determines whether the conditions for outputting the open instruction signal are met. For example, the open instruction signal output unit 102 determines, as the conditions for outputting the open instruction signal, whether an indoor activation signal has been acquired via the acquisition unit 101 and whether an outdoor activation signal has been acquired while a security release signal (authentication signal or permission signal) has been received. If the conditions for outputting the open instruction signal are not met (N in step S101), process S100 returns to the beginning of step S101 and repeats step S101. If the conditions for outputting the open instruction signal are met (Y in step S101), process S100 proceeds to step S102.

[0047] In step S102, the open instruction signal output unit 102 outputs an open instruction signal to the control unit 104.

[0048] In step S103, the control unit 104, in response to receiving the open instruction signal, determines whether or not it has received a limit signal. Here, the limit signal is output from the limit unit 103 to the control unit 104 when the limit unit 103 acquires the protection detection signal, which is output when the outdoor activation sensor 4A has detected an object within the protection detection area 71, via the acquisition unit 101. When the control unit 104 acquires the limit signal, it enters a state where it has received a limit signal. This state of having received a limit signal continues from the time the limit signal is received until the limit termination conditions described later are met. Alternatively, the state of having received a limit signal may end after a predetermined time has elapsed since the time the limit signal was received. If it is not in a state where it has received a limit signal (N in step S103), the process S100 proceeds to step S108.

[0049] When no restriction signal is received, there is no object to be detected in the protection detection area 71, so even if the door 9 is opened, the possibility of the object to be detected coming into contact with the door 9 is low. Therefore, in step S108, the control unit 104 activates the open instruction signal and opens the door 9. After step S108, process S100 ends.

[0050] When a restriction signal is received, the object to be detected is located within the protection detection area 71, so if the door 9 is opened, there is a risk that the object to be detected will come into contact with the door 9. Therefore, when a restriction signal is received (Y in step S103), the control unit 104 does not open the door 9, and processing S100 proceeds to step S104.

[0051] In step S104, the notification unit 105 causes the notification device 40 to notify that the door 9 cannot be opened. For example, the notification unit 105 causes the notification device 40 to display the message, "The door 9 cannot be opened because a person or object has been detected in the protection detection area 71."

[0052] In step S105, the control unit 104 determines whether the state in which the outdoor activation sensor 4A has detected an object within the protection detection area 71 has continued for a predetermined period of time during which the opening operation has been held. For example, the period of time during which the opening operation has been held can be about 30 seconds. If the detection state has not continued for the period of time during which the opening operation has been held (N in step S105), the process S100 proceeds to step S106.

[0053] In step S106, the control unit 104 determines whether the termination condition is met. In this embodiment, the termination condition is, for example, when the outdoor activation sensor 4A no longer detects a detection target within the protection detection area 71. Specifically, for example, this occurs when a detection target that was previously located within the protection detection area 71 leaves the protection detection area 71 and the door controller 91 no longer receives a protection detection signal. If the termination condition is met (Y in step S106), processing S100 proceeds to step S107. If the termination condition is not met (N in step S106), processing S100 returns to step S105, and steps S105 and S106 are repeated until the detection state continues for the open operation hold time (Y in step S106) or until the termination condition is met (Y in step S106).

[0054] In step S107, the notification unit 105 terminates the notification that the door 9 cannot be opened.

[0055] In step S108, the control unit 104 activates the open instruction signal and opens the door 9. After step S108, process S100 ends.

[0056] Returning to step S105, if the detection state persists for the opening operation hold time (Y in step S105), process S100 proceeds to step S109. In step S109, the notification unit 105 issues a final notification that the door 9 cannot be opened. For example, the notification unit 105 displays the message "The door could not be opened because a person or object was detected within the protection detection area 71" on the display of the notification device 40.

[0057] In step S110, the control unit 104 disables the open instruction signal and maintains the fully closed state of the door 9. After step S110, process S100 ends.

[0058] Here, if the door 9 is opened while a detection target is present in the protective detection area 71, there is a risk that the detection target may come into contact with the opening door 9. To counter this, for example, the risk of the collision can be reduced by not opening the door 9 when a detection target is present in the protective detection area 71.

[0059] However, when using this countermeasure, if a passerby attempts to pass through the automatic door device 100 while a target for detection is present in the protective detection area 71, the passerby may not understand why the door does not open. In particular, in automatic door devices 100 operated under security specifications such as those for apartment buildings (where automatic activation in the outdoor activation detection area 70A is disabled when the door is fully closed), for example, if the door 9 does not open when a passerby attempts to pass from the indoor side to the outdoor side, the fix 22, etc., may create a blind spot, making it difficult for the passerby and the target for detection in the protective detection area 71 installed on the outdoor side to see each other. As a result, there was room for improvement in terms of convenience, as passersby and the target for detection in the protective detection area 71 may not be able to understand what is happening.

[0060] In this embodiment, the restriction unit 103 outputs a restriction signal to restrict the opening operation of the door 9 under predetermined conditions, such as when the outdoor activation sensor 4A detects a target in the protective detection area 71. The notification unit 105 receives the restriction signal and, when an open command signal is output, notifies the notification device 40 that the door 9 cannot be opened. This configuration makes it possible for the notified person to understand that the door 9 is in a situation where it cannot be opened. Therefore, it becomes easier for the notified person to take appropriate action, such as checking for safety and removing the detected target from the protective detection area 71. Thus, it is possible to improve convenience while ensuring safety for the opening door 9.

[0061] In this embodiment, the predetermined condition in the limiting unit 103 is that the outdoor activation sensor 4A has detected a person or object within the protective detection area 71, and the statement that the door 9 cannot be opened includes the statement that the door 9 cannot be opened because a person or object has been detected within the protective detection area 71. With this configuration, the notified person can understand that a person or object is present within the protective detection area 71, making it easier for them to take appropriate actions such as confirming safety and removing the detected object from the protective detection area 71.

[0062] In this embodiment, when the control unit 104 receives an open command signal, it disables the open command signal if the state in which a person or object is detected in the protective detection area 71 continues for a predetermined period of time from the reception of the open command signal. The notification unit 105 notifies that the door cannot be opened if the state in which a person or object is detected in the protective detection area 71 continues for a predetermined period of time from the reception of the open command signal. If the open command signal is not disabled in such a situation, the door 9 will open even if there is no one in the protective detection area 71 who wants to pass through the opening 23 after the detected object has left the protective detection area 71. By disabling the open command signal, it is possible to prevent the door 9 from opening even when there is no one passing through the opening 23.

[0063] The following describes some variations.

[0064] The termination conditions for the restriction are not limited to the examples described above. For example, the termination condition for the restriction may be that a predetermined time has elapsed since the restriction on the opening operation of the door 9 began. The control unit 104 may determine whether or not at least one of the above-described termination conditions for the restriction is met.

[0065] In this embodiment, the door 9 was not opened at all, but it is also possible to open or close the door 9 to an extent that prevents a person from passing through, such as by opening the door 9 a few centimeters and then returning it to the fully closed position, or by closing the door 9 further from the fully closed position to deform the door edge rubber.

[0066] In this embodiment, an example is shown in which two activation sensors 4 are placed outdoors and indoors, respectively. However, the embodiment is not limited to this, and both activation sensors 4 may be placed indoors, or both may be placed outdoors.

[0067] In this embodiment, the outdoor activation sensor 4A sets the protective detection area 71, but the embodiment is not limited to this, and other sensors such as the indoor activation sensor 4B and the auxiliary photoelectric sensor 30 may also set the protective detection area 71. Furthermore, the protective detection area 71 may be set both outdoors and indoors.

[0068] In this embodiment, the protection detection area 71 consists of two areas, the first protection detection area 71A and the second protection detection area 71B, but it may also consist of only one of them.

[0069] In this embodiment, the door controller 91 opened the door 9 for pedestrians entering from inside the building based on the acquisition of an indoor activation signal, but is not limited to this; it may also open the door 9 based on the acquisition of both a security release signal and an indoor activation signal. Also in this embodiment, the door controller 91 opened the door 9 for pedestrians entering from outside the building based on the acquisition of both a security release signal and an outdoor activation signal, but is not limited to this; it may also open the door 9 based on the acquisition of an outdoor activation signal. Furthermore, the door controller 91 may open the door 9 based on the acquisition of a security release signal, regardless of the activation signal. Moreover, the door controller 91 may open the door 9 based only on the activation signal, without requiring a security release signal.

[0070] In this embodiment, the authentication device 51 is installed outdoors of the building where the automatic door device 100 is installed, but it is not limited to this. The authentication device 51 may be installed indoors, or it may be installed both outdoors and indoors.

[0071] In this embodiment, the door controller 91 determines whether to perform an open protection operation or a closed protection operation of the door 9 based on whether the door 9 is in a fully closed state, but it is not limited to this. For example, the automatic door sensor 10 may determine whether to perform an open protection operation or a closed protection operation of the door 9 by outputting a signal to perform an open protection operation and a signal to perform a closed protection operation of the door 9 based on whether the door 9 is in a fully closed state.

[0072] In this embodiment, the notification unit 105 did not notify in step S104 that the door 9 could not be opened, until it made a final notification in step S109, but is not limited to this. The notification unit 105 may periodically notify in step S106 until the restriction termination condition is met, or it may not notify in step S109 and only notify once in step S104.

[0073] The content of the notification by the notification unit 105 is not limited to those described above. For example, in addition to the fact that the door cannot be opened, the notification unit 105 may instruct the user to perform the operation to activate the door 9 again, such as "Please check your surroundings and try to activate the automatic door again." Alternatively, in addition to the fact that the door cannot be opened, the notification unit 105 may provide more detailed information as to why the door 9 cannot be opened, such as "The door could not be opened because the outdoor activation sensor was in a detection state in the protection detection area before it was fixed," by indicating at least one of the sensor that detected the object within the protection detection area 71 and the protection detection area 71 in which the object was detected.

[0074] If a restriction signal is received when an open instruction signal is received, the control unit 104 may invalidate the open instruction signal each time.

[0075] In this embodiment, if a predetermined opening operation hold time has elapsed in step S105, it is determined in step S106 whether or not the limit termination condition is met, but this is not limited to this. For example, in this case, the opening instruction signal output unit 102 may again determine whether or not the opening instruction signal output condition is met, and if the opening instruction signal output condition is not met, processing S100 may proceed to steps S109 and S110. Alternatively, for example, the determination of whether or not the limit termination condition is met may be made before the determination of whether or not the predetermined opening operation hold time has elapsed, and the determination of whether or not the opening instruction signal output condition is met may be made immediately after the outdoor activation sensor 4A stops detecting an object within the protection detection area 71, or the determination of whether or not the opening instruction signal output condition is met may be made after a predetermined time has elapsed.

[0076] In this embodiment, the notification unit 105 notified that the door 9 could not be opened by displaying a message, but is not limited to this; for example, it may also notify by voice, or by picture or image. Furthermore, the notification unit 105 may also notify that the door 9 could not be opened using video from an image sensor used as the activation sensor 4 or from a surveillance camera that includes the door 9 in its monitoring range.

[0077] Second Embodiment A second embodiment of the present invention will be described below. In the drawings and description of the second embodiment, components and members that are the same or equivalent as those in the first embodiment will be denoted by the same reference numerals. Descriptions that overlap with those of the first embodiment will be omitted as appropriate, and the description will focus on the configurations that differ from those of the first embodiment.

[0078] Figure 6 is a functional block diagram of the automatic door device 100 of the second embodiment. As shown in Figure 6, the automatic door device 100 of the second embodiment further includes an abnormality detection unit 106 and an operation information storage unit 107.

[0079] The abnormality detection unit 106 determines abnormalities in the components of the automatic door device 100 based on, for example, the operating information of the automatic door device 100. The components of the automatic door device 100 include, for example, the door controller 91, the door engine 92, the automatic door sensor 10, the transmission line 96 for communication between them, the door 9, etc. Furthermore, abnormalities in the components include, for example, that the components have failed to such an extent that they cannot properly operate to open the door 9, or that the components have deteriorated to such an extent that the door 9 cannot be safely opened or closed, such as when the opening and closing operation of the door 9 behaves differently than normal. The operating information of the automatic door device 100 includes, for example, information indicating the detection status of the automatic door sensor 10, information indicating the position of the door 9, information indicating the movement speed of the door 9, information indicating the drive voltage of the door engine 92, and information indicating the response characteristics of the door controller 91.

[0080] For example, the acquisition unit 101 acquires operational information from the door controller 91, door engine 92, automatic door sensor 10, etc., and stores it chronologically in the operational information storage unit 107. The abnormality determination unit 106 determines, for example, that there is an abnormality in the equipment constituting the automatic door device 100 when the chronological data of the operational information shows an abnormal value, and outputs an abnormality determination signal to the limiting unit 103. In this embodiment, the limiting unit 103 outputs a limiting signal to the control unit 104 in response to the acquisition of the abnormality determination signal. As a result, the control unit 104 enters a state where it has received the limiting signal.

[0081] In this embodiment, the notification unit 105 displays the message "The door cannot be opened due to a malfunction in the automatic door device 100" on the display of the notification device 40 in step S104 described above. Also, the notification unit 105 displays the message "The door could not be opened due to a malfunction in the automatic door device 100" on the display of the notification device 40 in step S109 described above.

[0082] Thus, in this embodiment, the predetermined condition in the limiting unit 103 is that the abnormality determination unit 106 determines an abnormality in the equipment constituting the automatic door device 100, and the notification unit 105 notifies that the door 9 cannot be opened due to an abnormality in the equipment of the automatic door device 100. With this configuration, the person who receives the notification can understand that the door 9 cannot be opened because there is an abnormality in the equipment constituting the automatic door device 100, making it easier for them to take appropriate action, such as informing the building manager that the automatic door device 100 is not working.

[0083] The abnormality detection unit 106 is not limited to the examples described above, and can determine abnormalities in the equipment constituting the automatic door device 100 using known methods.

[0084] Third Embodiment A third embodiment of the present invention will be described below. In the drawings and description of the third embodiment, components and members that are the same as or equivalent to those in the first embodiment will be denoted by the same reference numerals. Descriptions that overlap with those of the first embodiment will be omitted as appropriate, and the description will focus on the configurations that differ from those of the first embodiment.

[0085] Figure 7 is a block diagram illustrating the system configuration of the automatic door device 100 according to the third embodiment. As shown in Figure 7, in the third embodiment, notification devices 40A to 40C are provided on the automatic door device 100, the authentication device 51, and the open permission device 52, respectively. In the third embodiment, the notification unit 105 of the door controller 91 can notify the notification devices 40B and 40C of the authentication device 51 and the open permission device 52, in addition to the notification device 40A of the automatic door device 100, that the door 9 cannot be opened.

[0086] Figure 8 is a functional block diagram of the door controller 91 of the third embodiment. As shown in Figure 8, the door controller 91 further comprises a determination unit 108 and a signal storage unit 109.

[0087] Figure 9 is a flowchart of the process S200 of the door controller 91 in the third embodiment. Steps S201, S203-S204, and S206-S212 in Figure 9 are basically the same as steps S101-S110 in Figure 5, except for points that are specifically mentioned, so the explanation of the overlapping points will be omitted.

[0088] If the conditions for outputting the open instruction signal are met in step S201 (Y in step S201), processing S200 proceeds to step S202. In step S202, the signal storage unit 109 stores the signal that formed the basis for the determination that the conditions for outputting the open instruction signal are met. For example, if the conditions for outputting the open instruction signal are met based on the acquisition of an indoor start signal, the signal storage unit 109 stores the indoor start signal. If the conditions for outputting the open instruction signal are met based on the acquisition of an outdoor start signal while a security release signal (e.g., a permit signal) has been received, the signal storage unit 109 stores the outdoor start signal and its security release signal (permit signal).

[0089] After going through steps S203 to S204, in step S205, the decision unit 108 determines a notification device 40 that will notify that the door 9 cannot be opened. Specifically, the decision unit 108 decides to notify the notification device 40 corresponding to the device that output the signal stored in the signal storage unit 109 in step S202 that the door 9 cannot be opened. For example, if the signal stored in the signal storage unit 109 is an indoor activation signal, the decision unit 108 decides to notify the notification device 40A provided on the automatic door device 100 having an automatic door sensor 10 that output the indoor activation signal that the door 9 cannot be opened. Furthermore, for example, if the signal stored in the signal storage unit 109 is an outdoor activation signal and an authentication signal, the decision unit 108 decides to notify the notification device 40A provided on the automatic door device 100, including the automatic door sensor 10 that output the outdoor activation signal, and the notification device 40B provided on the authentication device 51 that output the authentication signal, that the door 9 cannot be opened. Furthermore, for example, if the signal stored in the signal storage unit 109 is an outdoor activation signal and an open permission signal, the decision unit 108 decides to notify the notification device 40A provided on the automatic door device 100, including the automatic door sensor 10 that output the outdoor activation signal, and the notification device 40C provided on the open permission device 52 that output the open permission signal, that the door 9 cannot be opened.

[0090] In steps S206 and S211, the notification unit 105 causes the notification device determined in step S205 to notify that the door 9 cannot be opened.

[0091] In this embodiment, notification devices 40B and 40C are provided on the authentication device 51 and the opening permission device 52, which are security release devices, respectively. When an opening instruction signal is output based on a security release signal, the notification unit 105 causes the notification device 40B or 40C provided on the security release device that output the security release signal to notify that the opening operation cannot be performed. With this configuration, a person who attempts to open the door 9 can be directly informed that the door 9 cannot be opened.

[0092] In this embodiment, when the authentication device 51 outputs an authentication signal, the notification device 40B provided on the authentication device 51 that output the authentication signal is notified that the door 9 cannot be opened. With this configuration, it is possible to make a passerby who is trying to open the door 9 using the authentication device 51 aware that the door 9 cannot be opened.

[0093] In this embodiment, when the opening permission device 52 outputs an opening permission signal, the notification device 40C provided on the opening permission device 52 that output the opening permission signal is notified that the door 9 cannot be opened. However, since the resident who outputs the opening permission signal using the opening permission device 52 from their room is located away from the automatic door device 100, they may not be able to understand that the door 9 has not opened or the reason why. With this configuration, it is possible to make the resident who tried to open the door 9 using the opening permission device 52 aware that the door 9 is not opening.

[0094] Furthermore, the notification unit 105 may notify other notification devices 40 that the door 9 cannot be opened, in addition to the notification device 40 related to the device that output the activation signal or security release signal, or it may notify only the notification device 40 related to the device that output the signal that the door 9 cannot be opened.

[0095] Any combination of the embodiments and modifications described above is also useful as an embodiment of the present invention. The new embodiments resulting from these combinations possess the combined effects of the respective embodiments and modifications. [Explanation of Symbols]
