Description

[Technical field]

[0001] The present invention relates to an opening and closing control system. [Background technology]

[0002] Conventionally, a system has been proposed for controlling the opening and closing movement of an opening / closing body of an automatic door device installed in an opening in a wall of a building. In such a system, for example, when the power is turned on, a learning operation is proposed to be performed before performing a normal opening and closing operation, by moving the opening / closing body to open and close, so as to learn how much stroke there is from when the opening is fully opened to when it is fully closed by the opening / closing body. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 63-171980 Summary of the Invention [Problem to be solved by the invention]

[0004] Here, the above-mentioned conventional system is also assumed to be applied to an automatic door device installed at the opening of a toilet booth in a building. In such a case, for example, when a user is using the toilet booth, if a power outage occurs and then the power is turned on again (so-called recovery from a power outage), as described above, a learning operation is performed before the normal opening and closing operation is performed, so there is a risk that the opening will be left open against the user's intention even though the user is using the toilet booth.

[0005] On the other hand, in order to avoid such problems, it is conceivable to provide the conventional system with an emergency power supply device capable of supplying power to the conventional system in the event of a power outage. However, since the emergency power supply device is very expensive, there is a concern that the installation cost of the system will be excessively high.

[0006] For these reasons, there is room for improvement in terms of system usability and installation costs.

[0007] The present invention is intended to solve the problems in the conventional technology described above, and has an object to provide an opening and closing control system that makes it possible to improve usability while suppressing installation costs. [Means for solving the problem]

[0008] In order to solve the above-mentioned problems and achieve the object, the opening / closing control system described in claim 1 is an opening / closing body constituting an automatic door device installed in a target space, and is an opening / closing control system for controlling the opening / closing movement of the opening / closing body which opens and closes a target opening / closing area in the target space, comprising: an opening / closing control means for detecting the arrival of an opening / closing timing to start the opening / closing movement of the opening / closing body; a normal opening / closing control which is a control for opening and closing the opening / closing body based on the detection result of the detection means; and an opening / closing control means for performing a learning opening / closing control which is a control performed at a predetermined timing before the normal opening / closing control is performed, and which identifies a fully open position corresponding to a fully open state in which the opening / closing body fully opens the target opening / closing area, and a fully closed position corresponding to a fully closed state in which the opening / closing body fully closes the target opening / closing area, by moving the opening / closing body in an opening / closing manner; a switching means for switching a supply state of power from an external power source to the switching control system between a continuous state in which the supply of the power is continued and a cut-off state in which the supply of the power is cut off, and the predetermined timing includes a return timing which is a timing at which the supply of the power is restored after being stopped, and a switching timing which is a timing different from the return timing and is a timing at which the supply state of the power is switched from the cut-off state to the continuous state by the switching means, When the return timing arrives, the switching control means continues the learning switching control until the detection means detects that the switching timing has arrived. Instead, after the switching means switches the power supply state from a continuous state to a cut-off state, it is determined whether the switching timing has arrived based on whether a switching signal indicating that the power supply state has been switched from the cut-off state to the continuous state by the switching means is received, and if it is determined that the switching timing has arrived by receiving the switching signal, the learning opening / closing control is performed regardless of the detection result of the detection means.

[0009] The opening / closing control system according to claim 2 is an opening / closing body constituting an automatic door device installed in a target space, and is an opening / closing control system for controlling the opening / closing movement of the opening / closing body which opens and closes a target opening / closing area in the target space, comprising: an opening / closing control means for detecting the arrival of an opening / closing timing to start the opening / closing movement of the opening / closing body; a normal opening / closing control which is a control for opening and closing the opening / closing body based on the detection result of the detection means; and an opening / closing control means for performing a learning opening / closing control which is a control performed at a predetermined timing before the normal opening / closing control is performed, and which is a control for identifying a fully open position corresponding to a fully open state in which the opening / closing body fully opens the target opening / closing area, and a fully closed position corresponding to a fully closed state in which the opening / closing body fully closes the target opening / closing area, by moving the opening / closing body in an opening / closing manner; A normally closed or normally open general-purpose control device; The opening / closing control means includes: a first opening / closing control means constituting the general-purpose control device, the first opening / closing control means controlling the opening / closing movement of the opening / closing body and performing the learning opening / closing control; and a second opening / closing control means configured separately from the first opening / closing control means, the second opening / closing control means controlling the first opening / closing control means based on a detection result of the detection means, When a restoration timing arrives, which is a timing at which the supply of power from an external power source to the switching control system is stopped and then restored, among the predetermined timings, the learning switching control is performed until the detection means detects that the switching timing has arrived. Furthermore, when the return timing arrives, the second opening / closing control means stops the execution of the learning opening / closing control by the first opening / closing control means by transmitting a learning stop signal to the first opening / closing control means to stop the execution of the learning opening / closing control until the detection means detects that the opening / closing timing has arrived.

[0010] The opening and closing control system according to claim 3 is the opening and closing control system according to claim 1 or 2, When the return timing arrives, the opening / closing control means performs the learning opening / closing control when the detection means detects that the opening / closing timing has arrived, and after the learning opening / closing control has been performed, performs the normal opening / closing control.

[0011] The opening / closing control system described in claim 4 is an opening / closing control system described in any one of claims 1 to 3, and is provided with a position detection means for detecting the position of the opening / closing body, and if the position of the opening / closing body detected by the position detection means immediately after the learning opening / closing control is performed is not a standby position where the opening / closing body is waiting to be opened or closed, the opening / closing control means performs an adjusted opening / closing control, which is a control for moving the opening / closing body to the standby position before performing the normal opening / closing control. Effect of the Invention

[0013] According to the opening and closing control system of claim 1, when the return timing arrives, the opening and closing control means does not perform learning opening and closing control until the opening and closing timing is detected by the detection means, so that when the return timing arrives while the user is using the target space, it is possible to prevent the opening and closing body from moving open or closed against the user's intention, thereby improving the usability of the opening and closing control system. Also, compared to the case where an emergency power supply device is provided, the opening and closing control system can be manufactured at low cost, and the installation cost of the opening and closing control system can be reduced. Furthermore, when the switching timing arrives, the opening / closing control means performs learning opening / closing control regardless of the detection result of the detection means, so that when the switching timing arrives, the learning opening / closing control can be performed more quickly than when the return timing arrives, further enhancing the usability of the opening / closing control system.

[0014] According to the opening and closing control system of claim 2, When the return timing arrives, the opening / closing control means does not perform learning opening / closing control until the opening / closing timing is detected by the detection means, so that when the return timing arrives while the user is using the target space, it is possible to prevent the opening / closing body from opening or closing against the user's intention, thereby improving the usability of the opening / closing control system. Also, compared to a case in which an emergency power supply device is provided, the opening / closing control system can be manufactured more inexpensively, and the installation cost of the opening / closing control system can be reduced. In addition, the opening / closing control means comprises a first opening / closing control means which controls the opening / closing movement of the opening / closing body, and a second opening / closing control means which is constructed separately from the first opening / closing control means and which controls the first opening / closing control means based on the detection results of the detection means. Therefore, there is no need to change the control content of the opening / closing control system according to the standby position of the opening / closing body, and the opening / closing movement of the opening / closing body can be controlled by directly using a general-purpose control device, thereby reducing the manufacturing costs of the opening / closing control system.

[0015] According to the opening and closing control system of claim 3, When the return timing arrives, the opening / closing control means performs learning opening / closing control when the detection means detects that the opening / closing timing has arrived, and after the learning opening / closing control has been performed, performs normal opening / closing control, so that normal opening / closing control can be performed accurately even when the return timing arrives, making it easier to maintain the usability of the opening / closing control system.

[0016] According to the opening / closing control system described in claim 4, if the position of the opening / closing body detected by the position detection means immediately after performing the learning opening / closing control is not the standby position, the opening / closing control means performs adjustable opening / closing control before performing normal opening / closing control, so that the opening / closing body can be automatically moved to the standby position after performing the learning opening / closing control, making it possible to perform normal opening / closing control smoothly.

[0019] An embodiment of the opening / closing control system according to the present invention will be described in detail below with reference to the accompanying drawings. First, [I] the basic concept of the embodiment will be described, then [II] specific contents of the embodiment will be described, and finally, [III] modified examples of the embodiment will be described. However, the present invention is not limited to the embodiment.

[0020] [I] Basic Concept of the Embodiment First, a basic concept of the embodiment will be described. The embodiment generally relates to an opening / closing control system for controlling the opening / closing movement of an opening / closing body that constitutes an automatic door device installed in a target space and that opens and closes a target area in the target space.

[0021] Here, the "target space" refers to the space in which the automatic door device is to be installed, and is a concept that includes, for example, toilet booths, changing rooms, conference rooms, etc. provided in a building.

[0022] In addition, the specific structure and type of the "building" are arbitrary, but the concept includes, for example, commercial facilities, office buildings, public facilities, and apartment complexes such as apartments and condominiums, but in this embodiment, it will be described as a commercial facility.

[0023] In addition, the "area to be opened and closed" is an area of ​​the target space that is the area to be opened and closed by an opening / closing body, and is a concept that includes, for example, an entrance / exit (opening) formed in a side wall that surrounds the target space.

[0024] In addition, the term "opening / closing body" refers to a structure for suppressing or restricting entry or exit to an opening / closing target area of ​​a target space, and is a concept that includes, for example, opening / closing bodies for automatic door devices.

[0025] Furthermore, the opening and closing structure of the opening and closing body is arbitrary, and can be configured as, for example, a single-opening door, a double-opening door, a single-sliding door, a sliding door, or a folding door.

[0026] In addition, in the embodiment, the "open / closed state of the opening / closing body" is a concept that includes a fully closed state, a fully open state, and a half-open state.

[0027] Among these, the "fully closed state" is a state in which the opening / closing target area is fully closed by the opening / closing body, and the position of the opening / closing body in this fully closed state is referred to as the "fully closed position."

[0028] Further, the "fully open state" refers to a state in which the opening / closing target area is fully opened by the opening / closing body, and the position of the opening / closing body in this fully open state is referred to as the "fully open position."

[0029] The "half-open state" is a state in which the opening / closing body is located between the fully closed position and the fully open position, and is a concept that includes a "half-open stopped state" in which a part of the opening / closing target area is open and stopped, a "half-open open movement state" in which the opening / closing body is moved to the open position, and a "half-open closed movement state" in which the opening / closing body is moved to the closed position. The position of the opening / closing body in this half-open state is referred to as the "half-open position."

[0030] In the following embodiments, a case will be described in which the opening / closing body of the automatic door system is a circular single-sliding door provided at an entrance (target opening / closing area) of a toilet booth (target space).

[0031] [II] Specific Contents of the Embodiments Next, the specific contents of the embodiment will be described.

[0032] (composition) First, the configuration of an automatic door system to which an opening / closing control system according to an embodiment of the present invention is applied will be described.

[0033] In the following explanation, the X direction in Fig. 1 is referred to as the left-right direction of the automatic door device (-X direction is the left direction of the automatic door device, and +X direction is the right direction of the automatic door device), the Y direction in Fig. 1 is referred to as the front-to-back direction of the automatic door device (+Y direction is the front direction of the automatic door device (toward the outside of the target space) and -Y direction is the rear direction of the automatic door device (toward the inside of the target space)), and the Z direction in Fig. 1 is referred to as the up-down direction of the automatic door device (+Z direction is the upward direction of the automatic door device, and -Z direction is the downward direction of the automatic door device).

[0034] The automatic door device 1 is a device for opening and closing a target area 3 (specifically, an entrance / exit) in a target space 2 (specifically, a toilet booth). As shown in Figures 1 and 2, the automatic door device 1 is provided in the front part of the target space 2, and includes a guide rail unit 10, an opening / closing body 20, an opening / closing drive unit 31, a lock unit 32, an output unit 33, and an opening / closing control system 40.

[0035] The connection configuration of each component constituting this automatic door device 1 is set as shown below. That is, the control device 50 of the opening / closing control system 40 described later is electrically connected to the opening / closing drive unit 31, the lock unit 32, the output unit 33, the inside detection unit 41, the position detection unit 42, and the switching unit 44 of the opening / closing control system 40 described later via wiring 4. This allows direct or indirect communication or power supply between the control device 50 described later and the opening / closing drive unit 31, the lock unit 32, the output unit 33, the inside detection unit 41, the position detection unit 42, and the switching unit 44 of the opening / closing control system 40 described later.

[0036] The method of mounting (or connecting) the various components that make up the automatic door device 1 is arbitrary; for example, a method of mounting (or connecting) the mounting side component to the mating component using fasteners (e.g. rivets, mounting screws, screws, etc.), welding, adhesives, double-sided tape, etc. through mounting holes (e.g. rivet holes, screw holes, screw holes, etc.) formed in the mounting side component or the mating component.

[0037] (Configuration-Target Space) Returning to Fig. 1, the target space 2 is surrounded by a plurality of walls 5 (for example, known wall panels, etc.) as shown in Fig. 1 and Fig. 2. A toilet 6 is provided inside the target space 2.

[0038] Among these, the multiple walls 5 are composed of a left side wall 5a, a right side wall 5b, a front wall 5c, and a rear wall 5d. Furthermore, the front wall 5c is composed of a leading side wall 5e located on the leading side of the opening / closing body 20, and a trailing side wall 5f located on the trailing side of the opening / closing body 20. The opening / closing target area 3 is provided between the leading side wall 5e and the trailing side wall 5f.

[0039] The toilet bowl 6 receives the user's urine and feces, and is constructed, for example, using a known toilet device, and is positioned inside the target space 2 in a position that does not interfere with the opening and closing movement of the opening / closing body 20 (in Figure 2, a position at the rear of the target space 2).

[0040] (Configuration - Guide rail section) The guide rail portion 10 guides the opening / closing body 20 to move substantially along the opening / closing direction (left / right direction) of the target opening / closing area 3. The guide rail portion 10 is a curved, elongated body formed so that its vertical cross section is substantially U-shaped, and is disposed substantially horizontally at or near the upper end of the target space 2. The guide rail portion 10 is directly fixed to the left side wall portion 5a, the right side wall portion 5b, and / or the front side wall portion 5c, or is indirectly fixed via a base material 11.

[0041] (Configuration - Opening and closing body) Returning to Fig. 1, the opening / closing body 20 is for opening and closing the target opening / closing area 3 of the target space 2. This opening / closing body 20 is configured, for example, using a known opening / closing body for an automatic door system (one example is an opening / closing panel for a circular single-sliding automatic door system). Specifically, it includes an opening / closing body frame (not shown) made of steel (for example, steel, stainless steel, etc.) and a surface material 21 (for example, a resin decorative panel, etc.) attached so as to cover the entire side surface in the prospective direction (front-rear direction) of the opening / closing body frame.

[0042] Further, the opening / closing body 20 is provided with a guided portion (not shown). The guided portion is for sliding the opening / closing body 20 on the guide rail portion 10. This guided portion is configured using, for example, a known guide roller or the like, and is attached so as to be slidable relative to the guide rail portion 10, and is connected to the opening / closing body 20 by a fixture or the like.

[0043] In addition, the specific configuration of the opening / closing body 20 is arbitrary, but in the embodiment, when the opening / closing body 20 is moved to open, the guided portion comes into contact with the end of the guide rail portion 10 on the door tail side, thereby restricting the opening / closing body 20 from moving beyond the fully open position. Also, when the opening / closing body 20 is moved to close, the door end side portion of the opening / closing body 20 comes into contact with a door stopper portion 5g provided on the door end side wall portion 5e, thereby restricting the opening / closing body 20 from moving beyond the fully closed position.

[0044] (Configuration - Opening and closing drive unit) The opening / closing drive unit 31 is an opening / closing drive means for electrically opening and closing the opening / closing body 20. This opening / closing drive unit 31 is configured, for example, using a known opening / closing drive means for a sliding door type automatic door device, and as shown in Figures 1 and 2, is provided on the door trailing end portion of the guide rail unit 10 and fixed to the guide rail unit 10 by a fixture or the like.

[0045] (Configuration - Lock part) Returning to Fig. 1, the lock unit 32 is a device for locking the opening / closing body 20. This lock unit 32 is configured using, for example, an electric lock for an automatic door device, and as shown in Fig. 1, is provided on the guide rail unit 10 and fixed to the guide rail unit 10 by a fixture or the like.

[0046] Furthermore, the specific operation when the lock unit 32 is an electric lock is arbitrary, but is, for example, as follows: In other words, in the normal opening and closing process described below, when the second full-close control described below is being performed, the lock unit 32 locks the opening and closing body 20, and when the first full-close control described below, the first full-open control described below, or the second full-open control described below is being performed, the lock unit 32 releases the lock on the opening and closing body 20.

[0047] (Configuration - Output section) The output unit 33 is an output means for outputting the usage status of the target space 2.

[0048] Here, the "usage status of the target space 2" is a concept that includes, for example, a presence status indicating whether or not a user is present in the target space 2, an abnormality status indicating whether or not an abnormality has occurred inside the target space 2, etc., but in the embodiment, it will be described as a presence status.

[0049] This output section 33 is constructed, for example, using a known output device (for example, an indicator light, etc.), and as shown in Figure 1, is provided on the door end side wall section 5e outside the target space 2 and fixed to the door end side wall section 5e by a fixing device or the like.

[0050] Furthermore, the output operation of the output unit 33 is arbitrary, but for example, it is as follows. That is, when the position of the opening / closing body 20 is the fully open position or the half-open position, it is determined that a user is not present in the target space 2, and the output unit 33 is turned off. On the other hand, when the position of the opening / closing body 20 is the fully closed position, it is determined that a user is present in the target space 2, and the output unit 33 is turned on in red.

[0051] (Configuration - Opening and closing control system) The opening / closing control system 40 is a system for controlling the opening / closing movement of the opening / closing body 20, and includes an inside detection unit 41, a position detection unit 42, a switching unit 44, and a control device 50, as shown in FIGS.

[0052] (Configuration - Opening and closing control system - Inside detection section) The inside detection unit 41 is a detection means that detects the arrival of an opening / closing timing, which will be described later, and is also an inside detection means that detects an inside opening / closing operation.

[0053] Here, the "inner opening / closing operation" refers to an operation performed by a user present inside the target space 2, which is an operation that serves as a trigger for starting the opening / closing operation of the opening / closing body 20.

[0054] This inside detection unit 41 is configured using, for example, a known detection sensor for an automatic door device (one example is a known non-contact detection sensor such as a transmission type photoelectric sensor), and specifically, includes a light transmitting unit that irradiates detection light, and a light receiving unit that is located above the light transmitting unit and receives the detection light irradiated from the light transmitting unit (both are not shown). Also, as shown in Fig. 2, this inside detection unit 41 is provided on the left side wall 5a inside the target space 2, and is fixed to the left side wall 5a by a fixture or the like.

[0055] Furthermore, when the inner detection unit 41 is a transmission type photoelectric sensor, the detection operation is, for example, as shown below. That is, when the detection light irradiated from the light transmitting unit of the inner detection unit 41 is blocked by the user's finger or the like, and the light receiving unit of the inner detection unit 41 cannot receive the detection light, a signal including information indicating that an inner opening / closing operation has been detected (hereinafter referred to as an "inner opening / closing operation signal") is output. On the other hand, when the light receiving unit can receive the detection light, the inner opening / closing operation signal is not output.

[0056] (Configuration - Opening and closing control system - Position detection unit) The position detection unit 42 is a position detection means that detects the position of the opening / closing body 20. This position detection unit 42 is configured using a known detection sensor such as a rotary encoder, and is provided in the vicinity of the opening / closing drive unit 31 and fixed to the opening / closing drive unit 31 by a fixture or the like.

[0057] Furthermore, when the position detection unit 42 is a rotary encoder, the detection operation involves, for example, counting the number of pulses output according to the position of the opening / closing body 20 from an origin position (in the embodiment, the fully closed position) using a counting means (not shown), and outputting a signal (hereinafter referred to as a "position detection signal") including count value information indicating the counted count value.

[0058] (Configuration - Opening and closing control system - Switching section) The switching unit 44 is a switching means that switches the power supply state (hereinafter simply referred to as the "power supply state") from an external power source (not shown) to the opening and closing control system 40 between a state in which power supply is continued (hereinafter referred to as the "continuous state") and a state in which power supply is cut off (hereinafter referred to as the "cut off state").

[0059] Here, "cutting off the power supply" means that the user (or another worker) uses the switching unit 44 to intentionally stop the power supply from the external power source.

[0060] Moreover, the term "external power source" refers to a power source provided outside the switching control system 40, and is a concept that includes, for example, a commercial power source.

[0061] The switching unit 44 is configured using, for example, known switching means (one example is a button-type changeover switch or the like), and is provided in the control device 50 as shown in FIG.

[0062] Furthermore, when the switching unit 44 is a button-type switch, the specific operation is arbitrary, but is, for example, as follows. That is, when the switching unit 44 switches the power supply state from a cut-off state to a continuous state by operation of the user (or other worker), it outputs a signal indicating that (hereinafter, referred to as a "switching signal"). On the other hand, when the switching unit 44 switches the power supply state from a continuous state to a cut-off state by operation of the user (or other worker), it does not output a switching signal.

[0063] (Configuration - Opening and closing control system - Control device) The control device 50 is a device for controlling the opening and closing control system 40, and includes a first control unit 60 and a second control unit 70, as shown in FIG.

[0064] (Configuration - Opening and closing control system - Control device - First control unit) The first control unit 60 is a unit that controls the opening and closing movement of the opening / closing body 20, and as shown in Fig. 3, includes a first communication unit 61, a first power supply unit 62, a first control unit 63, and a first storage unit 64. However, unless otherwise specified, the configuration of the first control unit 60 is the same as that of a general-purpose control device for a conventional automatic door device (specifically, a general-purpose control device with normally closed specifications), and therefore a description thereof will be omitted.

[0065] (Configuration - Opening and closing control system - Control device - First control unit - First communication unit) The first communication section 61 is a first communication means for communicating with the opening / closing drive section 31, the position detection section 42, and the second control unit 70 via the wires 4.

[0066] (Configuration - Opening and closing control system - Control device - First control unit - First power supply unit) The first power supply unit 62 is a first power supply means that supplies power supplied from an external power source to each part of the first control unit 60 via wiring 4, and also supplies power to the opening / closing drive unit 31 and the position detection unit 42 via wiring 4.

[0067] (Configuration - Opening and closing control system - Control device - First control unit - First control section) The first control unit 63 is a control means for controlling each part of the first control unit 60. Specifically, the first control unit 63 is a computer including a CPU, various programs interpreted and executed on the CPU (including basic control programs such as an OS, and application programs that are started on the OS and realize specific functions), and an internal memory such as a RAM for storing the programs and various data (note that the configuration of the second control unit 73 described later is substantially the same).

[0068] As shown in FIG. 3, the first control section 63 conceptually includes a first opening / closing control section 63a.

[0069] The first opening / closing control section 63a is an opening / closing control means that performs normal opening / closing control and learning opening / closing control, and is also a first opening / closing control means that controls the opening / closing movement of the opening / closing body 20.

[0070] Here, the term “normal opening / closing control” refers to control for moving the opening / closing body 20 to open or close based on the detection result of the inside detection unit 41.

[0071] In addition, "learning opening / closing control" refers to control that is performed at a predetermined timing before normal opening / closing control is performed, and that identifies the fully open position and the fully closed position by moving the opening / closing body 20 open and closed.

[0072] In addition, in the embodiment, the above-mentioned predetermined timing is a concept that includes the timing when the opening / closing process described later is started, the return timing, the switching timing, and the like.

[0073] Among these, "restore timing" refers to the timing at which power supply from an external power source to the opening / closing control system 40 is restored after being stopped. Also, "power supply is stopped" refers to power supply from an external power source being stopped against the will of the user (or other worker), and corresponds to, for example, power supply being stopped due to an external factor (such as a power outage, a broken power line, or the automatic door device 1 being unplugged, etc.).

[0074] Moreover, the "switching timing" refers to the timing at which the switching unit 44 switches the power supply state from a cut-off state to a continuous state.

[0075] Here, the reason why the learning opening / closing control is executed at the timing when the opening / closing process described later is activated is to identify the fully closed position and the fully open position so that the opening / closing body 20 can be opened and closed accurately with the fully closed position as the base position for control.

[0076] The reason for executing the learning opening / closing control after the restoration timing is as follows. That is, if the opening / closing movement of the opening / closing body 20 is manually performed while the supply of power from an external power source to the opening / closing control system 40 is stopped, the position of the opening / closing body 20 will shift, and the position detection unit 42 will not be able to accurately detect the position of the opening / closing body 20 when the power supply is restored. As a result, there is a risk that the opening / closing movement of the opening / closing body 20 cannot be accurately performed after the restoration, and this is to avoid the occurrence of such a problem (note that the reason for executing the learning opening / closing control after the switching timing is substantially the same).

[0077] Further, the specific control contents of the first opening / closing control section 63a are arbitrary, but in this embodiment, they are as follows.

[0078] That is, in the opening / closing process described later, the learning opening / closing control is executed after the timing when the opening / closing process described later is started, after the return timing, and after the switching timing. However, as described later, even after the return timing, if a learning stop signal (a signal to stop the execution of the learning opening / closing control) is received from the second opening / closing control unit 73a, the execution of the learning opening / closing control is stopped until the learning stop signal is no longer received, thereby preventing the opening / closing body 20 from moving open or closed against the user's intention.

[0079] Furthermore, among the opening and closing processes described below, at least in the processes of SA7 and SA8 described below, when an activation signal described below is not received from the second opening and closing control unit 73a, if the position of the opening and closing body 20 is the fully open position or the half open position, a close signal (a signal for moving the opening and closing body 20 to the closed position) is output to the opening and closing drive unit 31, thereby causing the opening and closing body 20 to move to the closed position by the opening and closing drive unit 31. Also, if the position of the opening and closing body 20 is the fully closed position, a stop signal (a signal for stopping the opening and closing movement of the opening and closing body 20) is output to the opening and closing drive unit 31, thereby causing the opening and closing movement of the opening and closing body 20 to be stopped by the opening and closing drive unit 31.

[0080] Furthermore, among the opening and closing processes described below, at least in the processes of SA7 and SA8 described below, when an activation signal described below is received from the second opening and closing control unit 73a, if the position of the opening and closing body 20 is the fully closed position or the half-open position, an open signal (a signal for moving the opening and closing body 20 to open) is output to the opening and closing drive unit 31, thereby causing the opening and closing body 20 to move to the open position by the opening and closing drive unit 31. Also, if the position of the opening and closing body 20 is the fully open position, a stop signal is output to the opening and closing drive unit 31, thereby causing the opening and closing movement of the opening and closing body 20 to be stopped by the opening and closing drive unit 31. Details of the processes executed by this first control unit 63 will be described later.

[0081] (Configuration-Opening and closing control system-Control device-First control unit-First storage unit) The first memory unit 64 is a first storage means for storing programs and various data necessary for the operation of the first control unit 60, and is constructed using a rewritable recording medium, and may use a non-volatile recording medium such as a flash memory (note that the configuration of the second memory unit 74 described later is substantially the same).

[0082] (Configuration - Opening and closing control system - Control device - Second control unit) The second control unit 70 is a unit that controls the first control unit 60 and is configured separately from the first control unit 60 (i.e., the second opening / closing control unit 73a described below is configured separately from the first opening / closing control unit 63a), and as shown in FIG. 3, includes a second communication unit 71, a second power supply unit 72, a second control unit 73, and a second memory unit 74.

[0083] (Configuration - Opening and closing control system - Control device - Second control unit - Second communication unit) The second communication unit 71 is a second communication means for communicating with the lock unit 32, the output unit 33, the inside detection unit 41, the position detection unit 42, the switching unit 44, and the first control unit 60 via the wiring 4.

[0084] (Configuration - Opening and closing control system - Control device - Second control unit - Second power supply unit) The second power supply unit 72 is a second power supply means that supplies power supplied from an external power source to each part of the second control unit 70 via wiring 4, and also supplies power to the lock unit 32, output unit 33, inner detection unit 41, position detection unit 42, and switching unit 44 via wiring 4.

[0085] (Configuration - Opening and closing control system - Control device - Second control unit - Second control section) The second control section 73 is a control means for controlling each section of the second control unit 70, and as shown in FIG. 3, conceptually includes a second opening / closing control section 73a and an opening / closing state determination section 73b.

[0086] The second opening / closing control unit 73a is an opening / closing control means that performs normal opening / closing control and learning opening / closing control, and is also a second opening / closing control means that controls the first opening / closing control unit 63a based on the detection result of the inner detection unit 41 and the determination result of the opening / closing state determination unit 73b.

[0087] Furthermore, the specific control content of this second opening / closing control unit 73a is arbitrary, but in the embodiment, this corresponds to controlling the first opening / closing control unit 63a by sending or not sending a signal indicating an instruction to move the opening / closing body 20 to the open position (hereinafter referred to as the "start signal") or a learning stop signal to the first opening / closing control unit 63a, depending on the processing content of the opening / closing process described below.

[0088] The open / close state specifying unit 73b is an open / close state specifying means for specifying the open / close state of the opening / closing body 20. Details of the processing executed by the second control unit 73 will be described later.

[0089] (Configuration-Opening and closing control system-Control device-Second control unit-Second memory unit) The second storage section 74 is a second storage means for storing programs and various data necessary for the operation of the second control unit 70.

[0090] Since such an opening / closing control system 40 can execute the opening / closing process described below, it is possible to prevent the opening / closing body 20 from moving open or closed against the user's will when the return timing arrives while the user is using the target space 2, thereby improving the usability of the opening / closing control system 40. Also, compared to a case in which an emergency power supply device is provided in the opening / closing control system 40, the opening / closing control system 40 can be manufactured at low cost, and the installation cost of the opening / closing control system 40 can be suppressed. Furthermore, it is not necessary to change the control content of the opening / closing control system 40 according to the standby position of the opening / closing body 20, and the opening / closing movement of the opening / closing body 20 can be controlled using a general-purpose control device as it is, thereby reducing the manufacturing cost of the opening / closing control system 40.

[0091] (Opening and closing process) Next, an opening / closing process executed by the first control section 63 of the first control unit 60 and the second control section 73 of the second control unit 70 configured as described above will be described. In the following description, steps will be abbreviated as "S" in the description of each process shown in Figs. 4 to 6.

[0092] The opening / closing process is a process for controlling the opening / closing movement of the opening / closing body 20. This opening / closing process can be executed at any timing, but in this embodiment, it will be described as being started after the automatic door system 1 is powered on.

[0093] The premise of the opening / closing process in this embodiment is as follows. That is, although not shown in Fig. 4, the following description will be given assuming that immediately after the opening / closing process is started when the automatic door system 1 is installed, the learning opening / closing process (SA5) described below has already been executed and the opening / closing body 20 is positioned in a standby position described below. Also, although not shown in Fig. 4, the first control unit 63 monitors whether the supply of power from an external power source to the opening / closing control system 40 has been stopped or cut off, and also monitors whether the supply of power has been restored if the supply of power has been stopped or cut off.

[0094] As shown in FIG. 4, at SA1, the second control section 73 determines whether or not the supply of power from an external power source to the opening and closing control system 40 has been stopped.

[0095] Specifically, a determination is made based on whether the amount of power supplied from an external power source is less than a threshold value, and if it is less than the threshold value, it is determined that the supply of power has been stopped, and if it is not less than the threshold value, it is determined that the supply of power has not been stopped.

[0096] Then, if the second control unit 73 determines that the supply of power has been stopped (SA1, Yes), it transitions to SA2, and if it determines that the supply of power has not been stopped (SA1, No), it transitions to SA4.

[0097] In SA2, the second opening / closing control section 73a determines whether or not the return timing has arrived.

[0098] While there is no particular method for determining whether the timing to return has arrived, in this embodiment, the method refers to the operation history information (information showing various operations of the automatic door system 1) stored in the second storage unit 74, and determines whether the amount of power supplied from the external power source has reached or exceeded a threshold immediately after the supply of power from the external power source has started after it has been determined that the supply of power has been stopped in SA2 since the opening / closing process was initiated (specifically, after the amount of power supplied from the external power source has fallen below a threshold).If the amount of power supplied from the external power source has reached or exceeded the threshold, it is determined that the timing to return has arrived, and if the amount of power supplied from the external power source has not reached or exceeded the threshold, it is determined that the timing to return has not arrived.

[0099] The second switching control unit 73a then waits until it is determined that the return timing has arrived (SA2, No). If it is determined that the return timing has arrived (SA2, Yes), the process proceeds to SA3. Furthermore, by transmitting a learning stop signal to the first switching control unit 63a until it is determined in SA3 that the opening / closing timing described below has arrived, the first switching control unit 63a stops executing a learning opening / closing process (SA5) described below when the return timing arrives.

[0100] In SA3, the second opening / closing control section 73a determines whether or not the timing to start the opening / closing movement of the opening / closing body 20 (hereinafter referred to as "opening / closing timing") has arrived.

[0101] The method for determining whether or not the opening / closing timing has arrived is arbitrary, but in the embodiment, the determination is made based on whether or not an inner opening / closing operation signal has been received from the inner detection unit 41, and if an inner opening / closing operation signal has been received, it is determined that the opening / closing timing has arrived, and if an inner opening / closing operation signal has not been received, it is determined that the opening / closing timing has not arrived.

[0102] Then, the second opening / closing control unit 73a waits until it is determined that the opening / closing timing has arrived (SA3, No), and if it is determined that the opening / closing timing has arrived (SA3, Yes), it stops sending a learning stop signal to the first opening / closing control unit 63a, thereby causing the first opening / closing control unit 63a to execute the learning opening / closing process (SA5).

[0103] By performing such processes from SA1 to SA3 and SA5, it is possible to prevent the opening / closing body 20 from opening or closing against the user's intention when the return timing arrives while the user is using the target space 2, compared to a case in which a learning operation is performed when the opening / closing control system 40 is powered on, thereby improving the usability of the opening / closing control system 40. Also, compared to a case in which an emergency power supply device is provided in the opening / closing control system 40, the opening / closing control system 40 can be manufactured at low cost, and the installation costs of the opening / closing control system 40 can be suppressed.

[0104] In SA4, the second switching control section 73a determines whether or not the switching timing has arrived.

[0105] The method for determining whether or not the switching timing has arrived is arbitrary, but in the embodiment, after the power supply state is switched from a continuous state to a cut-off state by the switching unit 44, the determination is made based on whether or not a switching signal has been received. If the switching signal has been received, it is determined that the switching timing has arrived, and if the switching signal has not been received, it is determined that the switching timing has not arrived.

[0106] Then, when the second opening / closing control unit 73a determines that the switching timing has arrived (SA4, Yes), it causes the first opening / closing control unit 63a to execute the learning opening / closing process (SA5) without sending a learning stop signal to the first opening / closing control unit 63a (i.e., causes the first opening / closing control unit 63a to execute the learning opening / closing process (SA5) regardless of the detection result of the inside detection unit 41), and when it determines that the switching timing has not arrived (SA4, No), it initiates the normal opening / closing process (SA8).

[0107] By performing such processing, when the switching timing arrives, the learning opening / closing processing can be performed more quickly than when the return timing arrives, thereby further improving the usability of the opening / closing control system 40.

[0108] (Opening / Closing Process - Learning Opening / Closing Process) Next, the learning opening / closing process of SA5 in FIG. 4 will be described.

[0109] The learning switching process is a process for performing learning switching control, and in the embodiment, it will be described as being executed based on a program installed in the first control unit 60.

[0110] When the learning opening / closing process is started, as shown in Fig. 5, in SB1, the first opening / closing control unit 63a moves the opening / closing body 20 to open by the opening / closing drive unit 31. Specifically, the opening movement is performed until it is determined in SB2 described later that the load amount of the opening / closing drive unit 31 is equal to or greater than a threshold value (more specifically, the opening movement of the opening / closing body 20 is performed at a slower speed than in the first full-open control in SC8 described later).

[0111] In SB2, the first opening / closing control section 63a determines whether or not the load amount of the opening / closing drive section 31 is equal to or greater than a threshold value.

[0112] Then, the first opening / closing control section 63a waits until it is determined that the voltage is equal to or greater than the threshold (SB2, No), and if it is determined that the voltage is equal to or greater than the threshold (SB2, Yes), the process proceeds to SB3.

[0113] In SB3, the first opening / closing control section 63a identifies the fully open position.

[0114] The method for identifying this fully open position is arbitrary, but in the embodiment, the position of the opening / closing body 20 corresponding to the position detection signal (specifically, the count value information contained in the position detection signal) received from the position detection unit 42 immediately before processing SB3 is identified as the fully open position.

[0115] In SB4, the first opening / closing control unit 63a moves the opening / closing body 20 to the closing position by the opening / closing drive unit 31. Specifically, the closing movement is performed until it is determined in SB5 described later that the load amount of the opening / closing drive unit 31 is equal to or greater than a threshold value and the movement distance of the opening / closing body 20 has reached a predetermined value (more specifically, the opening / closing body 20 is moved to the closing position at a slower speed than in the first full-close control in SC4 described later).

[0116] Furthermore, the method for setting this specified value is arbitrary, but for example, it may be set based on travel distance information stored in the second memory unit 74 (or the first memory unit 64) which indicates the travel distance (so-called stroke) of the opening / closing body 20 from the fully open position to the fully closed position, or it may be set based on travel distance information received from an external device (for example, a terminal device, etc.).

[0117] In SB5, the first opening / closing control unit 63a judges whether or not the load amount of the opening / closing drive unit 31 is equal to or greater than a threshold value and whether or not the movement distance of the opening / closing body 20 after the processing of SB4 is completed (specifically, the movement distance due to the closing movement of the opening / closing body 20) has reached a predetermined value (the movement distance indicated by the movement distance information) based on the detection result of the position detection unit 42. However, without being limited thereto, for example, the judgment may be made based only on whether or not it is equal to or greater than the threshold value, or based only on whether or not the movement distance of the opening / closing body 20 has reached a predetermined value.

[0118] Then, the first opening / closing control unit 63a waits until it is determined that the value is greater than or equal to the threshold and that the distance traveled by the opening / closing body 20 has reached a predetermined value (SB5, No), and if it is determined that the value is greater than or equal to the threshold and that the distance traveled by the opening / closing body 20 has reached a predetermined value (SB5, Yes), it transitions to SB6.

[0119] In SB6, the first switching control section 63a identifies the fully closed position and ends the learning switching process. Then, the second switching control section 73a transitions to SA6 in FIG. 4, triggered by the end of the learning switching process.

[0120] Furthermore, the method for identifying the fully closed position is arbitrary, but in this embodiment, the position of the opening / closing body 20 corresponding to the position detection signal received from the position detection unit 42 immediately before the processing of SB6 is identified as the fully closed position.

[0121] By the above-described learning opening / closing process, the fully open position and the fully closed position can be identified.

[0122] Returning to FIG. 4, in SA6, the second opening / closing control section 73a determines whether the opening / closing body 20 is in the standby position.

[0123] Here, the "standby position" refers to a position where the opening / closing body 20 waits for opening / closing movement, and in the embodiment, it is described as being the same position as the fully open position.

[0124] In addition, the method for determining whether or not the position of the opening / closing body 20 is the standby position is arbitrary, but in the embodiment, the determination is made based on whether or not the position of the opening / closing body 20 corresponding to the position detection signal received from the position detection unit 42 immediately before processing SA6 matches the fully open position identified in SB3, and if they match, it is determined to be the standby position, and if they do not match, it is determined to be not the standby position.

[0125] Then, when it is determined that the position of the opening-closing body 20 is the standby position (SA6, Yes), the second opening / closing control unit 73a starts the normal opening / closing process (SA8) (i.e., performs the normal opening / closing process after the learning opening / closing process).On the other hand, when it is determined that the position of the opening-closing body 20 is not the standby position (SA6, No), it proceeds to SA7.

[0126] In SA7, the second switching control section 73a performs adjustable switching control, and then starts normal switching processing (SA8) (that is, performs normal switching processing after performing learning switching processing).

[0127] Here, "adjusted opening / closing control" means control for moving the opening / closing body 20 to the standby position before normal opening / closing control is performed when the position of the opening / closing body 20 detected by the position detection unit 42 immediately after the learning opening / closing control is performed is not the standby position.

[0128] Furthermore, the specific control content of the adjusted opening / closing control is arbitrary, but in the embodiment, the second opening / closing control unit 73a causes the opening / closing body 20 to move open by sending an activation signal to the first opening / closing control unit 63a until the position of the opening / closing body 20 reaches the standby position (fully open position).

[0129] Furthermore, the method of transmitting this activation signal is arbitrary, and in the embodiment, the activation signal is transmitted continuously while the adjusted opening / closing control is being executed, but is not limited to this. For example, the activation signal may be transmitted intermittently, or may be transmitted only once (so-called pulse transmission) (the same applies to the first full-open control and the second full-open control described later).

[0130] By this processing, the opening / closing body 20 can be automatically moved to the standby position after the learning opening / closing control has been performed, and normal opening / closing control can be smoothly performed.

[0131] (Opening and closing process - normal opening and closing process) Next, the normal opening and closing process of SA8 in FIG. 4 will be described.

[0132] The normal opening / closing process is a process for performing normal opening / closing control.

[0133] When the normal opening / closing process is started, the opening / closing state specifying unit 73b specifies the opening / closing state of the opening / closing body 20 in SC1, as shown in FIG.

[0134] The method for determining the open / close state of the opening / closing body 20 is arbitrary, but in the embodiment, the state is determined based on the position detection signal received from the position detection unit 42 immediately before processing SC1 and the control signal (specifically, a close signal, an open signal, a stop signal) output from the first control unit 63 to the opening / closing drive unit 31 immediately before processing SC1.

[0135] For example, when the position of the opening / closing body 20 corresponding to the position detection signal is the fully open position and the control signal is a stop signal, it is identified as a fully open state. When the position of the opening / closing body 20 corresponding to the position detection signal is the fully closed position and the control signal is a stop signal, it is identified as a fully open state. When the position of the opening / closing body 20 corresponding to the position detection signal is the half-open position and the control signal is a close signal, it is identified as a half-open / closed movement state. When the position of the opening / closing body 20 corresponding to the position detection signal is the half-open position and the control signal is an open signal, it is identified as a half-open / open movement state.

[0136] In SC2, the opening / closing state specifying unit 73b determines whether the opening / closing state of the opening / closing body 20 specified in SC1 is the fully open state.

[0137] Then, if the opening / closing state specification unit 73b determines that the door is fully open (SC2, Yes), it proceeds to SC3, and if the opening / closing state specification unit 73b determines that the door is not fully open (SC2, No), it proceeds to SC6.

[0138] At SC3, the second opening / closing control section 73a determines whether or not an inside opening / closing operation signal is received from the inside detection section 41.

[0139] Then, if the second opening / closing control unit 73a determines that it has received an inner opening / closing operation signal (SC3, Yes), it transitions to SC4, and if it determines that it has not received an inner opening / closing operation signal (SC3, No), it transitions to SC5.

[0140] At SC4, the second opening / closing control section 73a performs the first full-close control. After that, the normal opening / closing process ends and the process proceeds to SA1, and thereafter the processes from SA1 to SA8 are repeated in the same manner.

[0141] Here, the "first full-close control" means controlling the first opening / closing control section 63a so that the position of the opening / closing body 20 becomes the full-close position.

[0142] Furthermore, the specific control content of the first full-close control is arbitrary, but in the embodiment, the second opening / closing control unit 73a does not send an activation signal to the first opening / closing control unit 63a until the opening / closing body 20 reaches a position that is a predetermined distance away from the fully open position in the closing direction, thereby causing the first opening / closing control unit 63a to move the opening / closing body 20 to the closed position.

[0143] Furthermore, the method for setting this specified distance is arbitrary, but for example, it may be set based on travel distance information stored in the second memory unit 74 (or the first memory unit 64), or it may be set based on travel distance information received from an external device (for example, a terminal device, etc.).

[0144] Furthermore, the method for setting this specified distance is arbitrary, but for example, it may be set based on travel distance information stored in the second memory unit 74 (or the first memory unit 64), or it may be set based on travel distance information received from an external device (for example, a terminal device, etc.).

[0145] At SC5, the second opening / closing control section 73a performs the second full-open control. After that, the normal opening / closing process ends and the process proceeds to SA1, and thereafter the processes from SA1 to SA8 are repeated in the same manner.

[0146] Here, the "second full-open control" means controlling the first opening / closing control section 63a so as to maintain the opening / closing state of the opening / closing body 20 in the fully open state.

[0147] Furthermore, the specific control content of the second full-open control is arbitrary, but in the embodiment, the second opening / closing control unit 73a sends an activation signal to the first opening / closing control unit 63a, causing the first opening / closing control unit 63a to stop the opening / closing movement of the opening / closing body 20 (specifically, preventing the opening / closing body 20 from moving in the closed direction).

[0148] By processing from SC2 to SC5 in this manner, when the standby position is set to the fully open position, the opening / closing body 20 can be opened or closed in accordance with the user's usage of the target space 2, thereby improving the usability of the opening / closing control system 40.

[0149] In SC6, the opening / closing state specifying unit 73b determines whether the opening / closing state of the opening / closing body 20 specified in SC1 is the fully closed state.

[0150] If the opening / closing state specification unit 73b determines that the door is in the fully closed state (SC6, Yes), it proceeds to SC7, and if the opening / closing state specification unit 73b determines that the door is not in the fully closed state (SC6, No), it proceeds to SC10.

[0151] In SC7, the second opening / closing control section 73a determines whether or not an inside opening / closing operation signal is received from the inside detection section 41.

[0152] Then, if the second opening / closing control unit 73a determines that it has received an inner opening / closing operation signal (SC7, Yes), it transitions to SC8, and if it determines that it has not received an inner opening / closing operation signal (SC7, No), it transitions to SC9.

[0153] In SC8, the second opening / closing control section 73a performs the first full-open control. After that, the normal opening / closing process ends and the process proceeds to SA1, and thereafter the processes from SA1 to SA8 are repeated in the same manner.

[0154] Here, the "first full-open control" means controlling the first opening / closing control section 63a so that the position of the opening / closing body 20 becomes the fully open position.

[0155] Furthermore, the specific control content of the first full-open control is arbitrary, but in the embodiment, the second opening / closing control unit 73a sends an activation signal to the first opening / closing control unit 63a, thereby causing the first opening / closing control unit 63a to move the opening / closing body 20 to the open position.

[0156] In SC9, the second opening / closing control section 73a performs the second full-close control. After that, the normal opening / closing process ends and the process proceeds to SA1, and thereafter the processes from SA1 to SA8 are repeated in the same manner.

[0157] Here, the "second full-close control" means controlling the first opening / closing control section 63a so as to maintain the opening / closing state of the opening / closing body 20 in the full-close state.

[0158] Furthermore, the specific control content of the second full-close control is arbitrary, but in the embodiment, the second opening / closing control unit 73a does not send an activation signal to the first opening / closing control unit 63a, thereby causing the first opening / closing control unit 63a to stop the opening / closing movement of the opening / closing body 20 (specifically, the opening / closing body 20 is not moved to the open position).

[0159] By processing from SC6 to SC9, when the standby position is set to the fully open position, the opening / closing body 20 can be opened or closed in accordance with the user's usage of the target space 2, further improving the usability of the opening / closing control system 40. Furthermore, by processing from SC2 to SC9, the user can smoothly enter and exit the target space 2 using only the inside detection unit 41, thereby reducing the installation cost of the opening / closing control system 40.

[0160] At SC10, the second opening / closing control section 73a performs half-open control (i.e., performs half-open control regardless of the detection result of the inside detection section 41). After that, the normal opening / closing process ends and the process proceeds to SA1, and thereafter the processes from SA1 to SA8 are similarly repeated.

[0161] Here, the "half-open control" means controlling the first opening / closing control section 63a so as to maintain the opening / closing state of the opening / closing body 20 in the half-open state.

[0162] The reason why the half-open control is performed regardless of the detection result of the inner detection unit 41 is as follows. That is, when the half-open control is performed based on the detection result of the inner detection unit 41, for example, between the first full-close control (movement of the opening / closing body 20 to close) of SC4 and the fully closed state, the inner detection unit 41 may erroneously detect the contact between the inner detection unit 41 and luggage or the like, and may perform control to move the opening / closing body 20 to open (so-called reversal control) instead of maintaining the closing movement of the opening / closing body 20. Such a control unintended by the user (such as the above-mentioned reversal control) may require the user to take the trouble of performing the inner opening / closing operation, which may reduce the usability of the opening / closing control system 40, and this is to avoid such a problem.

[0163] Further, the specific control content of the half-open control is arbitrary, but in this embodiment, it is as follows.

[0164] In other words, when the opening / closing state of the opening / closing body 20 identified in SC1 is a half-open movement state, the second opening / closing control unit 73a sends an activation signal to the first opening / closing control unit 63a, thereby causing the first opening / closing control unit 63a to continue the opening movement of the opening / closing body 20 (specifically, to continue the first full-open control).

[0165] In addition, when the opening / closing state of the opening / closing body 20 identified in SC1 is a half-open / closed movement state, the second opening / closing control unit 73a does not send an activation signal to the first opening / closing control unit 63a, thereby causing the first opening / closing control unit 63a to continue the closing movement of the opening / closing body 20 (specifically, causing the first full-close control to continue).

[0166] By such processing of SC10, when the door is in the half-open state, it is possible to prevent the half-open state from being not maintained due to the detection result of the inside detection unit 41, and the usability of the opening / closing control system 40 can be improved.

[0167] By the above-mentioned opening and closing process, when the return timing and the switching timing arrive, normal opening and closing control can be performed after the learning opening and closing control, and normal opening and closing control can be performed accurately. Also, the learning opening and closing control and normal opening and closing control can be performed accurately using the first control unit 60 and the second control unit 70, and it is not necessary to change the control content of the opening and closing control system 40 according to the standby position of the opening and closing body 20, and the opening and closing movement of the opening and closing body 20 can be controlled using a general-purpose control device as it is, thereby reducing the manufacturing cost of the opening and closing control system 40.

[0168] (Opening and closing process - specific process contents) Next, specific processing contents in which the opening and closing processing according to the embodiment is executed will be described below.

[0169] (Opening and closing process - specific process content - first specific example) First, the first specific example will be described.

[0170] As for the first specific example, after the opening and closing process is started and the normal opening and closing process of SA8 in FIG. 4 is performed, when the user uses the target space 2, the process shown below is performed.

[0171] That is, first, before the user enters the target space 2, the fully open state is determined in SC2 of Figure 6, and since the inner opening / closing operation signal is not received in SC3 of Figure 6, the fully open state is maintained by the second fully open control in SC5 of Figure 6.

[0172] Next, after the user enters the target space 2, when an inner opening / closing operation is detected by the inner detection unit 41 and an inner opening / closing operation signal is received in SC3 of Fig. 6, the opening / closing body 20 is moved to the closed position by the first full-close control in SC4 of Fig. 6. After that, if a full-close state is determined in SC6 of Fig. 6 and an inner opening / closing operation signal is not received in SC7 of Fig. 6, the full-close state is maintained by the second full-close control in SC9 of Fig. 6.

[0173] Next, just before the user leaves the target space 2, the inside detection unit 41 detects an inside opening / closing operation, and when an inside opening / closing operation signal is received in SC7 of Fig. 6, the opening / closing body 20 is moved to the open position by the first full-open control in SC8 of Fig. 6. After that, when the fully open state is determined in SC2 of Fig. 6, if an inside opening / closing operation signal is not received in SC3 of Fig. 6, the fully open state is maintained by the second full-open control in SC5 of Fig. 6. This allows the user to leave the target space 2.

[0174] Here, if a power outage occurs while the user is in the target space 2, first, it is determined in SA1 of FIG. 4 that the supply of power from the external power source to the opening / closing control system 40 has been stopped. Next, after it is determined that the return timing has arrived in SA2 of FIG. 4 due to the recovery of the power outage, the learning opening / closing process is not executed until the inner detection unit 41 detects the inner opening / closing operation, so that the opening / closing body 20 can be prevented from moving to an opening or closing position. After that, just before the user leaves the target space 2, when it is determined that the opening / closing timing has arrived in SA3 due to the inner detection unit 41 detecting the inner opening / closing operation, the learning opening / closing process in SA5 of FIG. 4 is executed. Then, after the opening / closing body 20 is moved to the standby position by the adjustment opening / closing control in SA7 of FIG. 4, the normal opening / closing process in SA8 of FIG. 4 is executed. This allows the user to leave the target space 2.

[0175] By the process corresponding to such a first specific example, when the standby position is set to a position corresponding to the fully open state, it is possible to perform opening / closing movement of the opening / closing body 20 according to the user's use of the target space 2. In addition, when the return timing arrives while the user is using the target space 2, it is possible to prevent the opening / closing body 20 from opening / closing movement against the user's intention.

[0176] (Opening and closing process - specific process content - second specific example) Next, the second specific example will be described.

[0177] As for the second specific example, after the opening / closing process is initiated and the normal opening / closing process of SA8 in FIG. 4 is performed, when the manager of the automatic door device 1 (hereinafter referred to as the "manager") performs maintenance work on the target space 2, the process shown below is carried out.

[0178] That is, first, before the administrator enters the target space 2, the fully open state is determined in SC2 of Figure 6, and since the inner opening / closing operation signal is not received in SC3 of Figure 6, the fully open state is maintained by the second full-open control in SC5 of Figure 6.

[0179] Next, after the manager enters the target space 2, when an inner opening / closing operation is detected by the inner detection unit 41 and an inner opening / closing operation signal is received in SC3 of Fig. 6, the opening / closing body 20 is moved to the closed position by the first full-close control in SC4 of Fig. 6. Next, if a fully closed state is determined in SC6 of Fig. 6 and an inner opening / closing operation signal is not received in SC7 of Fig. 6, the fully closed state is maintained by the second full-close control in SC9 of Fig. 6. After that, when the switching unit 44 switches the power supply state from a continuous state to a cut-off state by the manager's operation, the manager performs maintenance work.

[0180] Next, after the maintenance work is completed, the manager operates the switching unit 44 to switch the power supply state from the cut-off state to the continuous state, and when it is determined that the switching timing has arrived in SA4 of Fig. 4, the learning opening / closing process of SA5 of Fig. 4 is executed regardless of the detection result of the inside detection unit 41. Then, after the opening / closing body 20 is moved to the standby position by the adjusted opening / closing control in SA7 of Fig. 4, the normal opening / closing process of SA8 of Fig. 4 is executed. This allows the manager to leave the target space 2.

[0181] By processing corresponding to this second specific example, when the switching timing arrives while the administrator is using the target space 2, the learning opening / closing processing can be performed more quickly than when the return timing arrives.

[0182] (Effects of the embodiment) Thus, according to the embodiment, when the return timing arrives, the opening / closing control means does not perform learning opening / closing control until the arrival of the opening / closing timing is detected by the detection means, so that when the return timing arrives while the user is using the target space 2, it is possible to prevent the opening / closing body 20 from opening or closing against the user's intention, thereby improving the usability of the opening / closing control system 40. Furthermore, compared to the case where an emergency power supply device is provided, the opening / closing control system 40 can be manufactured more inexpensively, and the installation costs of the opening / closing control system 40 can be reduced.

[0183] In addition, when the return timing arrives, the opening / closing control means performs learning opening / closing control if the detection means detects that the opening / closing timing has arrived, and after the learning opening / closing control has been performed, performs normal opening / closing control, so that normal opening / closing control can be performed accurately even when the return timing arrives, making it easier to maintain the usability of the opening / closing control system 40.

[0184] Furthermore, when the switching timing arrives, the opening / closing control means performs learning opening / closing control regardless of the detection result of the detection means, so that when the switching timing arrives, the learning opening / closing control can be performed more quickly than when the return timing arrives, further enhancing the usability of the opening / closing control system 40.

[0185] Furthermore, if the position of the opening / closing body 20 detected by the position detection unit 42 immediately after performing the learning opening / closing control is not the standby position, the opening / closing control means performs adjustable opening / closing control before performing normal opening / closing control, so that the opening / closing body 20 can be automatically moved to the standby position after the learning opening / closing control is performed, making it possible to smoothly perform normal opening / closing control.

[0186] In addition, the opening / closing control means comprises a first opening / closing control unit 63a that controls the opening / closing movement of the opening / closing body 20, and a second opening / closing control unit 73a that is configured separately from the first opening / closing control unit 63a and controls the first opening / closing control means based on the detection results of the detection means. Therefore, there is no need to change the control content of the opening / closing control system 40 depending on the waiting position of the opening / closing body 20, and the opening / closing movement of the opening / closing body 20 can be controlled using a general-purpose control device as is, thereby reducing the manufacturing cost of the opening / closing control system 40.

[0187] [III] Modifications to the embodiment Although the embodiments of the present invention have been described above, the specific configurations and means of the present invention can be modified and improved as desired within the scope of the technical ideas of the inventions described in the claims. Such modifications will be described below.

[0188] (About the problem to be solved and the effects of the invention) First, the problems that the invention aims to solve and the effects of the invention are not limited to those described above, and the present invention may solve problems that are not described above or achieve effects that are not described above, or may solve only some of the problems that are described or achieve only some of the effects that are described.

[0189] (Regarding decentralization and integration) In addition, each of the electrical components described above is functionally conceptual, and does not necessarily have to be physically configured as shown in the figure. In other words, the specific form of distribution or integration of each part is not limited to that shown in the figure, and all or part of them can be functionally or physically distributed or integrated in any unit depending on various loads, usage conditions, etc. For example, the second control unit 70 may be distributed to multiple devices configured to be able to communicate with each other, and the second control unit 73 may be provided in some of these multiple devices, and the second storage unit 74 may be provided in another part of these multiple devices.

[0190] (shape, number, structure, time series) The components illustrated in the embodiments and drawings may be modified and improved as desired within the scope of the technical concept of the present invention with respect to the shape, numerical values, or structure or chronological relationships of multiple components.

[0191] (About automatic door systems) In the above embodiment, the automatic door system 1 is described as including the lock unit 32 and the output unit 33, but this is not limiting, and for example, at least one of the lock unit 32 and the output unit 33 may be omitted.

[0192] (Opening and closing control system) In the above embodiment, the switching control system 40 has been described as including the switching unit 44, but this is not limiting, and for example, the switching unit 44 may be omitted. In this case, the process of SA4 of the switching process may be omitted, and when it is determined in SA1 that the supply of power from an external power source to the switching control system 40 has not been stopped, the normal switching process (SA8) may be started.

[0193] (Detection methods) In the above embodiment, the detection means is described as including the inside detection unit 41, but is not limited thereto. For example, when the target space 2 is a conference room or the like, in addition to the inside detection unit 41, another different detection means (as an example, an outside detection means for detecting an outside opening / closing operation) may be provided. Note that the "outside opening / closing operation" refers to an operation performed by a user present outside the target space 2, and is an operation that serves as a trigger for starting the opening / closing operation of the opening / closing body 20.

[0194] In the above embodiment, the inner detection unit 41 is described as a transmission type photoelectric sensor, but the present invention is not limited to this and may be a quantum type infrared sensor or a push button switch.

[0195] (Regarding the control device) In the above embodiment, the control device 50 is described as including the first control unit 60 and the second control unit 70 that are configured separately, but this is not limited thereto. For example, it may be provided with one control unit having the functions of the first control unit 60 and the second control unit 70 (i.e., the first opening / closing control means and the second opening / closing control means may be integrated into one opening / closing control means). In this case, it is desirable to change the control content of the opening / closing control system 40 according to the standby position of the opening / closing body 20.

[0196] In the above embodiment, the first control unit 60 is described as being configured as a general-purpose control device of normally closed specifications, but this is not limited thereto. For example, when the target space 2 is a special workroom or the like, the first control unit 60 may be configured as a general-purpose control device of normally open specifications. In this case, the start signal may be a signal indicating an instruction to move the opening / closing body 20 to the closing position, the standby position may be set to the fully closed position, and the above-mentioned outer detection means may be provided instead of the inner detection unit 41.

[0197] (Regarding the second control section) In the above embodiment, the second control unit 73 is described as including the open / close state specification unit 73b, but this is not limiting, and for example, the open / close state specification unit 73b may be omitted. In this case, the inside detection unit 41 may include a first inside detection unit that detects an inside opening operation that is a trigger to start an opening operation of the opening / closing body 20, and a second inside detection unit that detects an inside closing operation that is a trigger to start a closing operation of the opening / closing body 20. In the normal opening / closing process, the second opening / closing control unit 73a may control the first opening / closing control unit 63a based on the detection results of the first inside detection unit and the second inside detection unit (i.e., based only on the detection results of the detection means).

[0198] As an example, in the normal opening / closing process, the second opening / closing control unit 73a may control the first opening / closing control unit 63a to maintain the opening / closing state of the opening / closing body 20 in a fully open state when the first inside detection unit has not detected an inward opening operation and the second inside detection unit has not detected an inward closing operation after the learning opening / closing control is performed and the opening / closing body 20 has been positioned to the standby position. Next, when the second inside detection unit detects an inward closing operation, the first opening / closing control unit 63a may be controlled to set the opening / closing state of the opening / closing body 20 to a fully closed state, and the first opening / closing control unit 63a may be controlled to maintain the opening / closing state of the opening / closing body 20 in a fully closed state until the first inside detection unit detects an inward opening operation. Next, when the first inside detection unit detects an inward opening operation, the first opening / closing control unit 63a may be controlled to set the opening / closing state of the opening / closing body 20 to a fully open state, and the first opening / closing control unit 63a may be controlled to maintain the opening / closing state of the opening / closing body 20 in a fully open state until the first inside detection unit detects an inward closing operation.

[0199] (About opening and closing process) In the above embodiment, the processes SA1 and SA2 are performed separately, but the present invention is not limited to this. For example, the processes SA1 and SA2 may be performed together. As an example, it may be determined whether or not the restoration timing has arrived after the power supply has been stopped in the opening / closing process, while referring to the operation history information stored in the second storage unit 74. Specifically, it may be determined based on whether or not the amount of power supply from the external power source has become equal to or greater than the threshold value when the power supply from the external power source is resumed after the amount of power supply from the external power source has become less than the threshold value in the opening / closing process.

[0200] In the above embodiment, the process of SA7 is performed, but the present invention is not limited to this, and for example, the process of SA7 may be omitted. In this case, if it is determined in SA6 that the position of the opening-closing body 20 is not the standby position, the opening-closing body 20 may be manually moved by an administrator or the like to open or close the opening-closing body 20 so that the opening-closing body 20 is at the standby position.

[0201] In the above embodiment, when it is determined that the switching timing has arrived in SA4, the learning opening / closing process (SA5) is started regardless of the detection result of the inside detection unit 41. However, this is not limited to this. For example, when it is determined that the switching timing has arrived in SA4, the inside detection unit 41 may detect that the opening / closing timing has arrived, and the learning opening / closing process (SA5) may be started.

[0202] (About learning opening and closing process) In the above embodiment, the opening / closing body 20 is opened to the fully open position to identify the fully open position, and then the opening / closing body 20 is closed to the fully closed position to identify the fully closed position, but this is not limited to the above. For example, the opening / closing body 20 may be opened to the fully closed position to identify the fully closed position, and then the opening / closing body 20 may be closed to the fully open position to identify the fully open position.

[0203] (Additional Note) The opening / closing control system of Supplementary Note 1 is an opening / closing body that constitutes an automatic door device installed in a target space, and is an opening / closing control system for controlling the opening / closing movement of the opening / closing body that opens and closes a target opening / closing area in the target space, and is equipped with: a detection means for detecting that an opening / closing timing has arrived for starting the opening / closing movement of the opening / closing body; a normal opening / closing control which is a control for moving the opening / closing body to open or close based on a detection result of the detection means; and an opening / closing control means for performing a learning opening / closing control which is a control performed at a predetermined timing before the normal opening / closing control is performed, and which is a control for identifying a fully open position corresponding to a fully open state in which the target opening / closing area is fully opened by the opening / closing body and a fully closed position corresponding to a fully closed state in which the target opening / closing area is fully closed by the opening / closing body by moving the opening / closing body to open or close, and when a return timing arrives which is a timing when the supply of power from an external power source to the opening / closing control system is stopped and then restored, among the predetermined timings, the opening / closing control means does not perform the learning opening / closing control until the detection means detects that the opening / closing timing has arrived.

[0204] The opening and closing control system of Appendix 2 is the opening and closing control system described in Appendix 1, wherein when the return timing arrives, the opening and closing control means performs the learning opening and closing control when the detection means detects that the opening and closing timing has arrived, and after the learning opening and closing control has been performed, performs the normal opening and closing control.

[0205] The opening and closing control system of Appendix 3 is the opening and closing control system described in Appendix 1 or 2, and further comprises a switching means for switching the power supply state between a continuing state in which the supply of power is continued and a cut-off state in which the supply of power is cut off, and the opening and closing control means performs the learning opening and closing control when a switching timing arrives among the specified timings, which is the timing at which the power supply state is switched from the cut-off state to the continuing state by the switching means, regardless of the detection result of the detection means.

[0206] The opening / closing control system of Appendix 4 is an opening / closing control system described in any one of Appendixes 1 to 3, and is provided with a position detection means for detecting the position of the opening / closing body, and if the position of the opening / closing body detected by the position detection means immediately after the learning opening / closing control is performed is not a standby position where the opening / closing body is waiting to be opened or closed, the opening / closing control means performs an adjusted opening / closing control which is a control for moving the opening / closing body to the standby position before performing the normal opening / closing control.

[0207] The opening / closing control system of Appendix 5 is an opening / closing control system described in any one of Appendix 1 to 4, wherein the opening / closing control means comprises a first opening / closing control means which controls the opening / closing movement of the opening / closing body, and a second opening / closing control means which is configured separately from the first opening / closing control means and which controls the first opening / closing control means based on the detection result of the detection means.

[0208] (Effect of supplementary notes) According to the opening / closing control system described in Appendix 1, when the return timing arrives, the opening / closing control means does not perform learning opening / closing control until the detection means detects that the opening / closing timing has arrived. Therefore, when the return timing arrives while the user is using the target space, it is possible to avoid the opening / closing body moving open or closed against the user's intention, thereby improving the usability of the opening / closing control system. Furthermore, compared to a case where an emergency power supply device is provided, the switching control system can be manufactured more inexpensively, and the installation costs of the switching control system can be reduced.

[0209] According to the opening and closing control system described in Appendix 2, when the return timing arrives, the opening and closing control means performs learning opening and closing control when the detection means detects that the opening and closing timing has arrived, and after the learning opening and closing control has been performed, performs normal opening and closing control, so that normal opening and closing control can be performed accurately even when the return timing arrives, making it easier to maintain the usability of the opening and closing control system.

[0210] According to the opening and closing control system described in Appendix 3, when the switching timing arrives, the opening and closing control means performs learning opening and closing control regardless of the detection result of the detection means, so that when the switching timing arrives, the learning opening and closing control can be performed more quickly than when the return timing arrives, further enhancing the usability of the opening and closing control system.

[0211] According to the opening / closing control system described in Appendix 4, if the position of the opening / closing body detected by the position detection means immediately after performing the learning opening / closing control is not the standby position, the opening / closing control means performs adjustable opening / closing control before performing normal opening / closing control, so that the opening / closing body can be automatically moved to the standby position after performing the learning opening / closing control, making it possible to perform normal opening / closing control smoothly.

[0212] According to the opening / closing control system described in Appendix 5, the opening / closing control means comprises a first opening / closing control means which controls the opening / closing movement of the opening / closing body, and a second opening / closing control means which is configured separately from the first opening / closing control means and which controls the first opening / closing control means based on the detection result of the detection means. Therefore, there is no need to change the control content of the opening / closing control system depending on the standby position of the opening / closing body, and the opening / closing movement of the opening / closing body can be controlled by directly using a general-purpose control device, thereby reducing the manufacturing cost of the opening / closing control system.
