Description

[Technical Field]

[0001] The present invention relates to a control system and a relay device. [Background technology]

[0002] Systems for controlling the opening and closing of shutter curtains in each of multiple electric shutter devices provided at each of multiple openings in a building have been proposed. For example, one such system has been disclosed, which includes multiple transceiver units provided at each of the multiple electric shutter devices and a master unit that relays signals transmitted from a mobile communication terminal to the multiple transceiver units (see, for example, Patent Document 1). In this system, a user operates multiple operation switches displayed on the screen of the mobile communication terminal, which are used to open, close, or stop the opening and closing of the shutter curtains of each electric shutter device (specifically, multiple operation switches each having an open button, a close button, and a stop button). The mobile communication terminal transmits an open signal, a close signal, or a stop signal corresponding to the operated operation switch. The transmitted open signal or the like is received by the corresponding transceiver unit via the master unit, allowing the system to control the opening and closing of the shutter curtains of the electric shutter devices provided at the corresponding transceiver units based on the open signal or the like received by the corresponding transceiver unit.

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2016-220015 Summary of the Invention [Problem to be solved by the invention]

[0004] In the base transceiver unit of the conventional system, for example, when sequentially transmitting a plurality of open signals and / or close signals received from a mobile communication terminal, it may take time to transmit all of the plurality of open signals and / or close signals. Therefore, if the base transceiver unit receives a stop signal from the mobile communication terminal while the plurality of open signals and / or close signals are being sequentially transmitted, the time required to transmit the stop signal may make it difficult to quickly stop the opening and closing movement of the shutter curtain of the electric shutter device corresponding to the stop signal. Therefore, there is room for improvement in terms of ensuring safety when using multiple opening and closing devices such as multiple electric shutter devices.

[0005] The present invention is intended to solve the problems in the above-described conventional technology, and has an object to provide a control system and a relay device that make it easier to ensure safety when using multiple switching devices. [Means for solving the problem]

[0006] In order to solve the above-mentioned problems and achieve the object, the control system described in claim 1 is a control system comprising a plurality of opening / closing devices provided at each of a plurality of openings in a building, and a relay device capable of communicating with the plurality of opening / closing devices and relaying an operation signal received from an operating device that operates the opening / closing devices to the plurality of opening / closing devices, wherein each of the plurality of opening / closing devices comprises an opening / closing body that opens and closes the opening, and an opening / closing control means that moves the opening / closing body open or closed based on the operation signal, the operation signal includes a stop operation signal that is a signal related to the operation of stopping the opening / closing movement of the opening / closing body, and the relay device comprises relay means that, when the operation signal received from the operating device is in a reserved state in which the operation signal received from the operating device is reserved, transmits the received stop operation signal to at least one of the plurality of opening / closing devices in priority to the reserved operation signal.

[0007] The control system according to claim 2 is the control system according to claim 1,When the stop operation signal is received in the hold state, if the hold operation signals include the stop operation signal, the relay means discards only the operation signals other than the stop operation signal among the hold operation signals.

[0008] The control system according to claim 3 is the control system according to claim 1, The operation signal includes opening / closing device identification information that uniquely identifies the opening / closing device, and when the stop operation signal is received in the pending state, the relay means discards only the operation signals that include the opening / closing device identification information that matches the opening / closing device identification information included in the received stop operation signal from among the pending operation signals.

[0009] The method according to claim 4 relay device teeth, The relay device is a plurality of opening / closing devices provided at each of a plurality of openings in a building, and is capable of communicating with a plurality of opening / closing devices, each of which has an opening / closing body that opens and closes the opening. The relay device relays operation signals received from an operating device that operates the opening / closing devices to the plurality of opening / closing devices, the operation signals including a stop operation signal that is a signal related to an operation to stop the opening / closing movement of the opening / closing body, and is provided with relay means that, when the stop operation signal is received while the operation signal received from the operating device is in a held state in which the operation signal is held, transmits the received stop operation signal to at least one of the plurality of opening / closing devices in priority to the held operation signal. [Effects of the Invention]

[0011] A control system according to claim 1, and Claim 4 According to the relay device described in the above, when a stop operation signal is received in a hold state, the relay device includes a relay means that transmits the received stop operation signal to at least one of the multiple opening / closing devices in priority over the held operation signal, so that in a hold state, the stop operation signal can be transmitted in priority over the held operation signal. Therefore, the opening / closing movement of the opening / closing body of at least one of the multiple opening / closing devices can be quickly stopped, making it easier to ensure safety when using the multiple opening / closing devices.

[0012] According to the control system of claim 2, When a stop operation signal is received in the reserved state, if the reserved operation signals include a stop operation signal, the relay means discards only the operation signals other than the stop operation signal among the reserved operation signals, so that, for example, the opening and closing movement of the opening and closing bodies of some of the opening and closing devices can be reliably stopped based on the reserved stop operation signal, ensuring the safety of those some of the opening and closing devices. Also, the opening and closing movement of the opening and closing bodies of other some of the opening and closing devices can be quickly stopped based on the received stop operation signal, making it easier to ensure the safety of those other some of the opening and closing devices.

[0013] According to the control system of claim 3, When a stop operation signal is received in the hold state, the relay means discards only operation signals that include opening / closing device identification information that matches the opening / closing device identification information included in the received stop operation signal, so that, for example, it is possible to reliably perform opening / closing movement of opening / closing bodies of some opening / closing devices or stop the opening / closing movement based on operation signals that include opening / closing device identification information that does not match the opening / closing device identification information included in the received stop operation signal, thereby maintaining the usability of some opening / closing devices. Also, it is possible to quickly stop the opening / closing movement of opening / closing bodies of other opening / closing devices based on the received stop operation signal, making it easier to ensure the safety of other some opening / closing devices.

DETAILED DESCRIPTION OF THE INVENTION

[0016] Hereinafter, with reference to the accompanying drawings, a control system and a relay device according to an embodiment of the present invention will be described in detail. First, [I] the basic concept of the embodiment will be described, then [II] specific content 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.

[0017] [I] Basic Concept of the Embodiment First, the basic concept of the embodiment will be described. The embodiment generally relates to a control system including a plurality of opening / closing devices provided at a plurality of openings in a building, and a relay device capable of communicating with the plurality of opening / closing devices and relaying an operation signal received from an operating device that operates the opening / closing devices to the plurality of opening / closing devices.

[0018] Here, the specific structure and type of "building" are arbitrary, but the concept includes, for example, public facilities, commercial facilities, detached houses, and collective housing such as apartments and condominiums.

[0019] Furthermore, an "opening" is an opening formed in a part of the building frame (for example, a wall material, a floor material, a ceiling material, etc.) for installing an entrance or a window.

[0020] Furthermore, the specific type of "opening and closing device" is arbitrary, but the concept includes, for example, shutter devices (examples include window shutters, heavy shutters, lightweight shutters, etc.), door devices (examples include swing doors, sliding doors, folding doors, etc.), and window devices. Furthermore, the opening and closing direction of the opening and closing body of the opening and closing device includes, for example, the up-down direction, the left-right direction, the front-rear direction, etc. Furthermore, the drive method of the opening and closing device is arbitrary, and for example, an "electric opening and closing device" is an example.

[0021] Furthermore, the specific type of "operation device" is arbitrary, but for example, it is a remote operation device for an opening and closing device, and is a concept that includes a remote operation device for remotely operating the opening and closing device, and a terminal device different from the remote operation device, and a communication device (for example, a mobile terminal, a management server, etc.) that is capable of transmitting operation signals, but in the embodiment, it will be described as a mobile terminal (specifically, a smartphone) on which an app that enables transmission of operation signals is installed.

[0022] Furthermore, the specific type of "operation signal" is arbitrary, but the concept includes, for example, an open signal, a close signal, a stop operation signal, and the like.

[0023] Of these, the "open signal" is a signal for moving the opening / closing body of a specific opening / closing device to the open position, and the "close signal" is a signal for moving the opening / closing body of a specific opening / closing device to the close position.

[0024] Furthermore, the "stop operation signal" is a signal related to the operation of stopping the opening and closing movement of the opening and closing body of at least one opening and closing device, and is a concept that includes, for example, a first stop operation signal, a second stop operation signal, a third stop operation signal, etc.

[0025] Here, the "first stop operation signal" is a signal for stopping the opening / closing movement of the opening / closing body of a specific opening / closing device. The "second stop operation signal" is a signal for simultaneously stopping the opening / closing movement of each of the opening / closing bodies of multiple opening / closing devices while receiving a response signal to the second stop operation signal. The "third stop operation signal" is a signal for urgently stopping the opening / closing movement of each of the opening / closing bodies of multiple opening / closing devices, regardless of whether a response signal to the third stop operation signal is received.

[0026] The "response signal" is a signal that includes information indicating that the operation signal has been received.

[0027] Furthermore, the specific type of "relay device" is arbitrary, but the concept includes a relay device for a switching device and a relay server (for example, a network server, a cloud server, etc.) that can relay other signals in addition to operation signals to devices other than the switching device. In the embodiment, however, it will be described as a relay device for a switching device.

[0028] In the following embodiments, a case will be described in which the opening and closing device is a vertically opening and closing type electrically operated window shutter that is installed in an opening provided in the outer wall of a building such as a detached house.

[0029] [II] Specific details of the embodiment Next, specific details of the embodiment will be described.

[0030] First Embodiment First, a description will be given of a control system according to embodiment 1. In this embodiment 1, a relay device discards all operation signals that are on hold.

[0031] (composition) First, the configuration of the control system according to the embodiment will be described.

[0032] In the following explanation, the X direction in FIG. 1 is referred to as the left-right direction of the control system (the -X direction is the left direction of the control system, and the +X direction is the right direction of the control system), the Y direction in FIG. 1 is referred to as the up-down direction of the control system (the +Y direction is the up direction of the control system, and the -Y direction is the down direction of the control system), and the direction perpendicular to the X and Y directions is referred to as the front-to-back direction (the direction leading to the front side of the paper in FIG. 1 is the front direction of the control system, and the direction leading to the back side of the paper in FIG. 1 is the rear direction of the control system).

[0033] The control system 1 is a system for controlling a plurality of opening and closing devices 10 and a relay device 80, which will be described later, and is generally equipped with a plurality of opening and closing devices 10 (two opening and closing devices 10 in FIG. 1) and a relay device 80, as shown in FIG.

[0034] (Configuration - Switchgear) First, the configuration of the multiple opening and closing devices 10 will be described.

[0035] The multiple opening and closing devices 10 are devices for opening and closing multiple openings 2 (two openings 2 in FIG. 1 ) provided in the framework of a building (for example, the outer wall of a building, etc.). As shown in FIG. 1 , each of the multiple opening and closing devices 10 is provided around each opening 2, and generally includes a storage section 20, a guide rail 30, an opening and closing body 40, an opening and closing machine 50, a winding shaft (not shown), and an opening and closing control system 60. However, unless otherwise specified, the configuration of each opening and closing device 10 is the same as that of a conventional shutter device (specifically, a top-and-bottom opening and closing type and an electric type window shutter), and therefore description thereof will be omitted.

[0036] The connection configuration of each component constituting each opening / closing device 10 is set as shown below. That is, an opening / closing control unit 70 of an opening / closing control system 60 (described later) is electrically connected to each of the opening / closing device 50, an opening / closing operation section 61, a position detection section 62, a rotation speed detection section 63, and an obstacle detection section 64 of the opening / closing control system 60 (described later) via wiring 3. This allows communication or power supply directly or indirectly between the opening / closing control unit 70 (described later) and each of the opening / closing device 50, the opening / closing operation section 61, the position detection section 62, the rotation speed detection section 63, and the obstacle detection section 64 (described later).

[0037] In the following, as necessary, of the multiple opening and closing devices 10, the opening and closing device 10a located on the left side of Figure 1 will be referred to as the "first opening and closing device 10a," and the opening and closing device 10b located on the right side of Figure 1 will be referred to as the "second opening and closing device 10b."

[0038] (Configuration - Switching device - Storage section) The storage section 20 is a hollow body for storing each part of the opening / closing device 10. As shown in FIG. 1 , the storage section 20 is installed above the upper end of the opening 2. The storage section 20 also stores the opening / closing machine 50, the winding shaft, and a position detection section 62, a rotation speed detection section 63, an obstacle detection section 64, and an opening / closing side control unit 70 of the opening / closing side control system 60, which will be described later. When the opening / closing body 40 is wound up by the winding shaft, at least a part of the opening / closing body 40 is also stored inside the storage section 20.

[0039] (Configuration - Switching device - Guide rail) The guide rail 30 guides the opening / closing body 40 to move along the opening / closing direction (vertical direction) of the opening 2. The guide rail 30 is an elongated body formed so that its cross section is roughly U-shaped, and is disposed at each of the left and right ends of the opening / closing device 10 in a direction roughly along the vertical direction, and is fixed directly to the wall of the building or indirectly via a base material (not shown).

[0040] (Configuration - Switching device - Switching body) The opening / closing body 40 is a shielding means that switches the open / closed state of the opening / closing body 40 by being moved to close or open by the winding shaft.

[0041] Here, the "open / closed state of the opening / closing body 40" is a concept that includes a "fully closed state," a "fully open state," and a "half-open state." Of these, the "fully closed state" is a state in which the opening 2 is fully closed by the opening / closing body 40, and the position of the opening / closing body 40 in the fully closed state is referred to as the "fully closed position." Furthermore, the "fully open state" is a state in which the opening 2 is fully opened by the opening / closing body 40, and the position of the opening / closing body 40 in the fully open state is referred to as the "fully open position." Furthermore, the "half-open state" is a state in which the opening / closing body 40 is positioned between the fully closed position and the fully open position.

[0042] 1, the opening / closing body 40 includes a plurality of slats 41, which are fitted and connected to one another via fitting portions (not shown) formed at both upper and lower ends of each slat 41. Each of the left and right ends of the opening / closing body 40 is inserted into the inside of the guide rail 30 via the U-shaped open end of the guide rail 30, and is slidable within the guide rail 30 in the up and down direction, but is restricted from falling out of the guide rail 30 in the front and rear direction.

[0043] A seat plate 42 is connected to the closed end of the opening / closing body 40 (specifically, the lower end of the opening / closing body 40). The seat plate 42 is disposed so as to be in close proximity to or in contact with the floor surface of the building in the fully closed state, and is formed over the entire length of the closed end of the opening / closing body 40 in the left-right direction.

[0044] (Configuration - Switchgear - Switchgear) The opening / closing device 50 is a driving means for electrically opening and closing the opening / closing body 40 by controlling the rotation of the winding shaft. The opening / closing device 50 is configured, for example, by a known opening / closing device (for example, an opening / closing device with a brake or a brakeless opening / closing device), and is provided inside the storage section 20 in a position near the winding shaft, as shown in FIG.

[0045] (Configuration - Opening and closing device - Winding shaft) The winding shaft is a rotating shaft for moving the opening / closing body 40 to close or open. This winding shaft is configured using, for example, a known winding shaft or the like, and is installed along the left-right direction. In addition, a connecting slat (not shown) that is connected to the upper end of the opening / closing body 40 is connected to this winding shaft, and by rotating this winding shaft, the opening / closing body 40 can be moved to close or open via the connecting slat. In addition, the left end (or right end) of this winding shaft is connected to the output shaft of the opening / closing device 50 via a chain (not shown), so the winding shaft can be rotated in conjunction with the rotation of the output shaft of the opening / closing device 50.

[0046] (Configuration - Switchgear - Switching side control system) The opening / closing side control system 60 is for controlling the opening / closing device 10, and as shown in Figure 1, it includes an opening / closing side operation unit 61, a position detection unit 62, a rotation speed detection unit 63, an obstacle detection unit 64, and an opening / closing side control unit 70.

[0047] (Configuration - Switchgear - Switching Control System - Switching Operation Unit) The opening / closing side operation unit 61 is an opening / closing side operation means that receives operation inputs related to the opening / closing movement of the opening / closing body 40. This opening / closing side operation unit 61 is configured using, for example, a known wired operation device, and as shown in Fig. 1, is provided near the opening 2, and includes an open button that electrically moves the opening / closing body 40 to the open position, a close button that electrically moves the opening / closing body 40 to the closed position, and a stop button that stops the electrically moved closing or opening position (all of which are not shown).

[0048] Furthermore, the specific operation of the opening / closing side operating unit 61 is arbitrary, but in embodiment 1, when the open button, close button, or stop button is pressed by the user, an operation signal corresponding to the pressed button (i.e., an open signal, close signal, or first stop operation signal including opening / closing device identification information for uniquely identifying the opening / closing device 10) is output to the opening / closing machine 50 via the opening / closing side control unit 70, so that the opening / closing body 40 can be electrically moved open or closed by the opening / closing machine 50, or the opening / closing movement of the opening / closing body 40 can be electrically stopped.

[0049] (Configuration - Switching device - Switching control system - Position detection unit, rotation speed detection unit) The position detection unit 62 is a position detection means for detecting the position of the opening / closing body 40 (specifically, the position of the lower end of the opening / closing body 40) and outputting a signal indicating the detected position (hereinafter referred to as a "position signal") at a predetermined interval, and is provided inside the opening / closing machine 50 as shown in Figure 1.

[0050] The rotation speed detection unit 63 is a position detection means for detecting the rotation speed of the drive unit of the opening / closing machine 50 (hereinafter referred to as the "rotation speed of the drive unit") and outputting a signal indicating the detected rotation speed (hereinafter referred to as the "rotation speed signal") at a predetermined period, and is provided inside the opening / closing machine 50 as shown in Figure 1.

[0051] The specific configurations of the position detection unit 62 and the rotation speed detection unit 63 are arbitrary, but in the first embodiment, they are configured using a Hall IC or the like that has the functions of both the position detection unit 62 and the rotation speed detection unit 63. However, this is not limiting, and for example, the position detection unit 62 may be configured using an encoder (or potentiometer) or the like, and the rotation speed detection unit 63 may be configured using a tachogenerator or the like.

[0052] In the first embodiment, the opening / closing side control system 60 does not include an upper limit switch or a lower limit switch, so in order to execute the relay process described later, it is necessary to set a fully open position (upper limit position) and a fully closed position (lower limit position). The fully open position and the fully closed position may be set by any method, but may be set, for example, by the method shown below (hereinafter referred to as the "manual setting method").

[0053] That is, first, an operator performs a predetermined operation via the opening / closing side operation unit 61 to set the control mode of the opening / closing device 10 to a mode for setting a fully open position and a fully closed position (hereinafter referred to as a "limit setting mode"). Next, in the limit setting mode, an operator operates the open button of the opening / closing side operation unit 61 to move the opening / closing body 40 to an open position so that the opening / closing state of the opening / closing body 40 becomes the fully open state. Next, when the lower end portion (the end portion of the opening / closing body 40 on the closing direction side) of the opening / closing body 40 abuts against the lintel, the voltage value or current value (i.e., the load amount of the drive unit) of the opening / closing device 50 reaches a threshold value, and the position of the opening / closing body 40 corresponding to the position signal acquired from the position detection unit 62 is set as the fully open position. Next, an operator operates the close button of the opening / closing side operation unit 61 to move the opening / closing body 40 to a closed position so that the opening / closing state of the opening / closing body 40 becomes the fully closed state. Next, when the lower end of the opening / closing body 40 abuts against the floor surface, the voltage value or current value (i.e., the load amount of the drive unit) of the opening / closing mechanism 50 reaches a threshold value, and the position of the opening / closing body 40 corresponding to the position signal obtained from the position detection unit 62 is set as the fully closed position.

[0054] (Configuration - Switching device - Switching control system - Obstacle detection unit) The obstacle detection unit 64 is an obstacle detection means that detects obstacles (e.g., people, animals, objects, etc.) that hinder the opening and closing movement of the opening / closing body 40, and is configured using, for example, a known obstacle detection sensor (one example is an overload detection sensor), etc., and is provided inside the opening / closing machine 50, as shown in Figure 1.

[0055] Furthermore, the method for detecting an obstacle by the obstacle detection unit 64 is arbitrary, and may be, for example, as follows: That is, the voltage value or current value of the drive unit of the switchgear 50 is acquired over time each time the switchgear body 40 is moved to close, and of the acquired voltage values ​​or current values, the voltage value or current value acquired in the closing movement of the switchgear 50 immediately before the closing movement of the target switchgear 50 is set as the learned value. Then, based on the number of times that the voltage value or current value acquired during the closing movement of the target switchgear 50 exceeds the learned value, it is determined whether the switchgear 50 is in an overload state, and if the switchgear 50 is in an overload state, it is detected that an obstacle is present, and if the switchgear is not in an overload state, it is detected that no obstacle is present.

[0056] Furthermore, the specific operation of the obstacle detection unit 64 is arbitrary, but in embodiment 1, when the lower end of the opening / closing body 40 comes into contact with an obstacle, an obstacle detection signal indicating that an obstacle has been detected is output to the opening / closing side control unit 70, and when the lower end of the opening / closing body 40 does not come into contact with an obstacle, an obstacle detection signal is not output to the opening / closing side control unit 70.

[0057] (Configuration - Switchgear - Switching Control System - Switching Control Unit) The opening / closing side control unit 70 is a device that interconnects each part of the opening / closing device 10, and as shown in Figure 1, is provided inside the opening / closing machine 50 (or inside the storage section 20, but outside the opening / closing machine 50, etc.), and as shown in Figure 2, is equipped with a first opening / closing side communication section 71, a second opening / closing side communication section 72, an opening / closing side power supply section 73, an opening / closing side control section 74, and an opening / closing side memory section 75.

[0058] (Configuration - Switchgear - Switching side control system - Switching side control unit - First switching side communication unit) The first opening / closing side communication unit 71 is a first opening / closing side communication means for communicating between the opening / closing machine 50, the opening / closing side operation unit 61, the position detection unit 62, the rotation speed detection unit 63, or the obstacle detection unit 64 and the opening / closing side control unit 70, and is configured using, for example, a known communication means for communicating using a wired communication network.

[0059] (Configuration - Switchgear - Switching side control system - Switching side control unit - Second switching side communication unit) The second opening / closing side communication unit 72 is a second opening / closing side communication means for communicating between the opening / closing side control unit 70 and the relay device 80, and is configured using, for example, a known communication means for communicating using a wireless communication network (for example, a communication means for short-range wireless communication (for example, a communication means using a short-range wireless communication standard such as specific low-power radio), or a communication means for long-range wireless communication (for example, a communication means using a long-range wireless communication standard such as 4G, 5G, or LTE (registered trademark)).

[0060] (Configuration - Switchgear - Switching control system - Switching control unit - Switching power supply) The opening / closing side power supply unit 73 is an opening / closing side power supply means that supplies power supplied from a commercial power source or a battery (e.g., a battery, etc.) not shown to each part of the opening / closing side control unit 70, and also supplies power to the opening / closing side operating unit 61, position detection unit 62, rotation speed detection unit 63, obstacle detection unit 64, etc.

[0061] (Configuration - Switchgear - Switching control system - Switching control unit - Switching control section) The opening / closing side control unit 74 is an opening / closing side control means that controls each part of the opening / closing side control unit 70. Specifically, it is a computer that is configured with a CPU, various programs that are 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 RAM for storing programs and various data (note that the same applies to the configuration of a relay-side control unit 84 of a relay device 80, which will be described later).

[0062] As shown in FIG. 2, the opening / closing control section 74 conceptually includes an opening / closing control section 74a.

[0063] The opening / closing control unit 74 a is an opening / closing control means that moves the opening / closing body 40 to open or close based on an operation signal received from the relay device 80 or an operation signal input from the opening / closing side operation unit 61 .

[0064] (Configuration - Switchgear - Switching Control System - Switching Control Unit - Switching Memory Unit) The opening / closing side memory unit 75 is an opening / closing side memory means that stores programs and various data (for example, opening / closing device identification information for uniquely identifying its own opening / closing device 10) necessary for the operation of the opening / closing side control unit 70, and is configured using a rewritable recording medium, and a non-volatile recording medium such as a flash memory can be used (the same applies to the configuration of the relay side memory unit 85 of the relay device 80 described later).

[0065] (Configuration - Relay device) Returning to FIG. 1, the configuration of relay device 80 will now be described.

[0066] The relay device 80 is a device capable of communicating with a plurality of opening and closing devices 10 (specifically, a first opening and closing device 10a and a second opening and closing device 10b), and is a device that relays an operation signal received from an operation device that operates the opening and closing devices 10 (specifically, a smartphone installed with an app that enables transmission of the operation signal) to the plurality of opening and closing devices 10. As shown in FIG. 1, the relay device 80 is provided in the vicinity of the plurality of opening and closing devices 10, and as shown in FIG. 3, includes a relay-side operation unit 81, a relay-side communication unit 82, a relay-side power supply unit 83, a relay-side control unit 84, and a relay-side memory unit 85. Note that, unless otherwise specified, configurations of the relay device 80 are the same as those of conventional relay devices for opening and closing devices, and description thereof will be omitted.

[0067] In addition, in embodiment 1, the relay device 80 communicates operation signals, etc. with each of the multiple opening and closing devices 10 corresponding to the multiple opening and closing device identification information registered (stored) in the relay side memory unit 85.

[0068] Here, the method for transmitting the operation signal in the operation device is arbitrary, but in the first embodiment, the operation signal is transmitted as follows.

[0069] That is, when a user presses any of the multiple open buttons, multiple close buttons, or multiple first stop buttons displayed on the display unit of the operating device, which correspond to each opening / closing device 10, an operation signal corresponding to the pressed button (specifically, an open signal, a close signal, or a first stop operation signal including opening / closing device identification information that uniquely identifies the opening / closing device 10 corresponding to the pressed button) is transmitted. Also, when a user presses one second stop button or one third stop button displayed on the display unit of the operating device, which corresponds to all of the multiple opening / closing devices 10, an operation signal corresponding to the pressed button (specifically, a second stop operation signal corresponding to the second stop button, or a third stop operation signal corresponding to the third stop button) is transmitted.

[0070] (Configuration - Relay device - Relay side operation unit) The relay side operation unit 81 is a relay side operation means for receiving operation inputs relating to various information. This relay side operation unit 81 is configured using a known operation device such as a hard switch or a touch panel, and has setting buttons (not shown) for making various settings relating to the relay device 80.

[0071] (Configuration - Relay device - Relay side communication unit) The relay side communication unit 82 is a relay side communication means for communicating between the relay device 80 and the opening / closing device 10 (specifically, the opening / closing side control unit 70) and each of the operating devices, and is configured using, for example, a known communication means for communicating using a wireless communication network (for example, a communication means for short-range wireless communication, a communication means for long-range wireless communication, or a communication means having both of these functions).

[0072] (Configuration - Relay device - Relay side power supply unit) The relay-side power supply unit 83 is a relay-side power supply means that supplies power supplied from a commercial power supply or a battery (not shown) to each unit of the relay device 80.

[0073] (Configuration - Relay device - Relay side control unit) The relay-side control unit 84 is a relay-side control means that controls each unit of the relay device 80, and as shown in FIG. 3, conceptually includes a relay unit 84a.

[0074] The relay unit 84a is a relay means that, when a stop operation signal is received while an operation signal received from an operating device is on hold (hereinafter referred to as the "on hold state"), prioritizes the received stop operation signal over the on hold operation signal and transmits the received stop operation signal to at least one of the multiple opening and closing devices 10, and when an operation signal other than a stop operation signal (specifically, an open signal or a close signal) is received from the operating device, transmits the operation signal to one of the multiple opening and closing devices 10.

[0075] (Configuration - Relay device - Relay side memory unit) The relay-side storage unit 85 is a relay-side storage means that stores programs and various data necessary for the operation of the relay device 80 (for example, a plurality of pieces of switching device identification information for uniquely identifying each switching device 10).

[0076] (Relay processing) Next, a description will be given of the relay process executed by the relay-side control unit 84 of the relay device 80 configured as described above. In the following description, steps will be abbreviated as "S" in the description of each process shown in FIG.

[0077] The relay process is a process for relaying an operation signal received from an operating device to a plurality of opening and closing devices 10 (specifically, the first opening and closing device 10a and the second opening and closing device 10b). The timing for executing this relay process is arbitrary, but in the first embodiment, the relay process will be described as being started after the power of the relay device 80 is turned on.

[0078] Furthermore, as a premise for the relay processing, it is assumed that, in each opening / closing device 10, the control mode is set to the limit setting mode before the relay processing, and thus the fully open position and the fully closed position are respectively set.

[0079] When the relay process is initiated, as shown in FIG. 4, in SA1, the relay unit 84a of the relay device 80 determines whether or not an operation signal other than a stop operation signal (specifically, an open signal or a close signal including opening / closing device identification information) has been received from the operation device.

[0080] Then, if the relay unit 84a of the relay device 80 determines that the operation signal has been received (SA1, Yes), it proceeds to SA2, and if it determines that the operation signal has not been received (SA1, No), it proceeds to SA3.

[0081] In addition, in embodiment 1, the operation signal received at SA1 is temporarily stored in the relay side memory unit 85, and when a response signal to the operation signal is received from a specific opening / closing device 10 at SA2 described below, the stored operation signal is erased.

[0082] In SA2, the relay unit 84a of the relay device 80 transmits the operation signal (specifically, an operation signal other than a stop operation signal) received in SA1 to a specific opening / closing device 10 (specifically, either the first opening / closing device 10a or the second opening / closing device 10b), and receives a response signal to the transmitted operation signal from the specific opening / closing device 10, and then transitions to SA1.

[0083] The received operation signal may be transmitted in any manner, but in the first embodiment, it is transmitted as follows.

[0084] That is, first, the relay unit 84a of the relay device 80 transmits the received operation signal to the multiple opening / closing devices 10. Next, after receiving the transmitted operation signal, the opening / closing-side control unit 74 of each of the multiple opening / closing devices 10 determines whether the opening / closing device identification information included in the received operation signal matches the opening / closing device identification information stored in the opening / closing-side memory unit 75. If the opening / closing device identification information matches, the received operation signal is considered to have been transmitted to a specific opening / closing device 10, and the opening / closing control unit 74a of each of the multiple opening / closing devices 10 performs opening / closing control of the opening / closing body 40 based on the received operation signal, and transmits a response signal (specifically, a response signal including the opening / closing device identification information stored in the opening / closing-side memory unit 75) to the relay device 80. On the other hand, if the opening / closing device identification information does not match, the received operation signal is considered not to have been transmitted to a specific opening / closing device 10, and the opening / closing control unit 74a of each of the multiple opening / closing devices 10 does not perform opening / closing control of the opening / closing body 40 based on the received operation signal, and does not transmit a response signal.

[0085] As an example, if the received operation signal transmitted by the relay unit 84a of the relay device 80 includes opening / closing device identification information that uniquely identifies the first opening / closing device 10a, the opening / closing control unit 74a of the first opening / closing device 10a controls the opening / closing of the opening / closing body 40 based on the operation signal, since the opening / closing device identification information matches the opening / closing device identification information included in the received operation signal, and transmits a response signal including the opening / closing device identification information that uniquely identifies the first opening / closing device 10a to the relay device 80. On the other hand, the opening / closing control unit 74a of the second opening / closing device 10b does not control the opening / closing of the opening / closing body 40 based on the received operation signal, since the opening / closing device identification information does not match the opening / closing device identification information included in the received operation signal, and does not transmit a response signal.

[0086] In this case, the specific processing contents of the opening / closing control of the opening / closing body 40 by the opening / closing control section 74a are arbitrary, but in the first embodiment, they are as follows.

[0087] That is, when a closing signal transmitted by SA2 is received, the opening / closing body 40 is electrically moved to the closing position by the opening / closing device 50, and when an opening signal transmitted by SA2 is received, the opening / closing body 40 is electrically moved to the opening position by the opening / closing device 50.

[0088] Furthermore, after the closing signal or opening signal transmitted by SA2 is received, the opening / closing body 40 can be electrically moved to close or open without the user having to operate the closing button or opening button on the operating device, so that the opening / closing body 40 continues to move to close or open even after reception of the closing signal or opening signal has ended (so-called "opening / closing control of the opening / closing body 40 by self-holding operation" is performed).

[0089] Furthermore, from the viewpoint of enhancing safety during use, for example, when the opening / closing control of the opening / closing body 40 is being performed based on an operation signal transmitted by SA2, if an input of an open signal, a close signal, or a first stop operation signal is received via the opening / closing-side operation unit 61, the opening / closing control of the opening / closing body 40 based on the operation signal transmitted by SA2 is stopped, and the opening / closing control of the opening / closing body 40 is performed based on the open signal, the close signal, or the first stop operation signal received via the opening / closing-side operation unit 61 (that is, priority is given to control of the open / closed state of the opening / closing body 40 based on an open signal, etc., received via the opening / closing-side operation unit 61. The same applies to the case where the opening / closing control of the opening / closing body 40 is being performed based on a stop operation signal transmitted by SA6, which will be described later). However, this is not limiting, and for example, when the opening / closing control of the opening / closing body 40 is being performed based on an operation signal transmitted by SA2, even if an input of an open signal, a close signal, or a first stop operation signal is received via the opening / closing-side operation unit 61, the opening / closing control of the opening / closing body 40 based on the operation signal transmitted by SA2 may be continued.

[0090] Furthermore, the method for receiving the response signal is arbitrary, but in the first embodiment, it is determined whether or not the switching device identification information included in the response signal transmitted from the switching device 10 matches the switching device identification information included in the operation signal transmitted at SA2, and if these switching device identification information match, it is determined that the response signal has been received from the specific switching device 10, and if these switching device identification information do not match, it is determined that the response signal has not been received from the specific switching device 10 (note that the method for receiving response signals to each of the first stop operation signal and the second stop operation signal at SA6 described later is substantially the same). Furthermore, when the response signal is received, it is determined that the operation signal stored in the relay-side memory unit 85 and corresponding to the response signal is erased.

[0091] In SA3, the relay unit 84a of the relay device 80 determines whether or not a stop operation signal (specifically, the first stop operation signal, the second stop operation signal, or the third stop operation signal) has been received from the operation device.

[0092] Then, if the relay unit 84a of the relay device 80 determines that the stop operation signal has been received (SA3, Yes), it proceeds to SA4, and if it determines that the stop operation signal has not been received (SA3, No), it proceeds to SA1.

[0093] In SA4, the relay unit 84a of the relay device 80 determines whether or not the call is in a hold state.

[0094] Here, the "hold state" in embodiment 1 corresponds to the following: a situation in which a large number of operation signals are received at SA1, and / or a communication failure has occurred, and therefore at least some of the received operation signals are not transmitted at SA2 but remain (stored) in the relay-side memory unit 85 of the relay device 80; a situation in which, when processing SA3 is performed in parallel with processing SA6 described below, the stop operation signal received at SA3 before processing SA6 is the second stop operation signal or the third stop operation signal, and / or a communication failure has occurred, and therefore the received stop operation signal is not transmitted at SA6 described below but remains in the relay-side memory unit 85 of the relay device 80; or a situation in which the operation signal received at SA1 or the stop operation signal received at SA3 has been transmitted, but a response signal to the operation signal or the stop operation signal has not been received, and therefore the operation signal or the stop operation signal remains in the relay-side memory unit 85 of the relay device 80.

[0095] For example, if an operation signal (hereinafter referred to as a "second operation signal") is further received from the operation device after an operation signal (hereinafter referred to as a "first operation signal") is received at SA1 and before the first operation signal is transmitted to the specific opening / closing device 10, this second operation signal remains in the relay-side storage unit 85, and therefore corresponds to the hold state. Also, if a second operation signal is further received from the operation device after the first operation signal received at SA1 is transmitted to the specific opening / closing device 10 and before a response signal to the first operation signal is received from the specific opening / closing device 10, these first operation signal and second operation signal remain in the relay-side storage unit 85 of the relay device 80, and therefore correspond to the hold state.

[0096] For example, if a response signal to a first operation signal is not received from a specific opening / closing device 10 within a predetermined time (for example, within 1 to 2 seconds) after the first operation signal is transmitted to the specific opening / closing device 10, the relay unit 84a of the relay device 80 may retransmit the first operation signal to ensure that the response signal is received.

[0097] In the first embodiment, the processes of SA1 and SA2 are executed in parallel with the processes of SA3 to SA6, which will be described later. As a result, for example, a hold state may occur while the processes of SA1 and SA2 are executed in parallel. Furthermore, if a response signal is received at SA2 in the hold state, the process of SA2 is executed in parallel, which enables the relay unit 84a of the relay device 80 to transmit the operation signal remaining in the relay-side memory unit 85 (or the stop operation signal received at SA3) to the specific opening / closing device 10, and also enables the relay unit 84a to receive a response signal to the operation signal, etc.

[0098] Furthermore, the method for determining whether or not the state is on hold is arbitrary, but in embodiment 1, when processing SA4, the determination is made based on whether or not the operation signal received at SA1 (or the stop operation signal received at SA3) remains in the relay side memory unit 85, and if the operation signal, etc. remains in the relay side memory unit 85, it is determined that the state is on hold, and if the operation signal, etc. does not remain in the relay side memory unit 85, it is determined that the state is not on hold.

[0099] Then, if the relay unit 84a of the relay device 80 determines that the call is in a hold state (SA4, Yes), it proceeds to SA5, and if the relay unit 84a determines that the call is not in a hold state (SA4, No), it proceeds to SA6.

[0100] In SA5, the relay unit 84a of the relay device 80 discards the operation signal that has been held.

[0101] The method for discarding the operation signals is arbitrary, but in the first embodiment, all of the reserved operation signals are discarded.

[0102] Specifically, all operation signals stored in the relay side storage unit 85 during the processing of SA5 are deleted and discarded.

[0103] Such processing by SA5 makes it possible to avoid opening or closing the opening / closing body 40 based on the reserved operation signal after the stop operation signal received by SA3 has been preferentially transmitted, and makes it easier to ensure safety when using multiple opening / closing devices 10. Furthermore, since all reserved operation signals are discarded, the most recently received stop operation signal can be transmitted preferentially, and it becomes possible to quickly perform opening / closing control of at least one opening / closing body 40 of the multiple opening / closing devices 10 based on the stop operation signal.

[0104] In SA6, the relay unit 84a of the relay device 80 transmits the stop operation signal received in SA3 to at least one of the plurality of opening and closing devices 10, and / or receives a response signal to the transmitted stop operation signal from at least one of the plurality of opening and closing devices 10. Thereafter, the process proceeds to SA1, and similarly thereafter, the processes from SA1 to SA6 are repeated.

[0105] Here, the stop operation signal may be transmitted in any manner, but in the first embodiment, it is transmitted as follows.

[0106] That is, when the stop operation signal is the first stop operation signal, the first stop operation signal is transmitted using the same method as the method for transmitting the operation signal in SA2.

[0107] In addition, if the stop operation signal is a second stop operation signal, a second stop operation signal including opening / closing device identification information that uniquely identifies that opening / closing device 10 is sent to one of the multiple opening / closing devices 10, and after a response signal to the sent second stop operation signal is received, a second stop operation signal including opening / closing device identification information that uniquely identifies that opening / closing device 10 is sent to the next opening / closing device 10.This process is repeated until the second stop operation signal is sent to all of the multiple opening / closing devices 10 (specifically, the multiple opening / closing devices 10 corresponding to the multiple opening / closing device identification information registered in the relay side memory unit 85).

[0108] As an example, a second stop operation signal including opening / closing device identification information that uniquely identifies the first opening / closing device 10a may be sent to the first opening / closing device 10a, and after a response signal to the sent second stop operation signal is received, a second stop operation signal including opening / closing device identification information that uniquely identifies the second opening / closing device 10b may be sent to both the first opening / closing device 10a and the second opening / closing device 10b.

[0109] Furthermore, when the stop operation signal is a third stop operation signal, the third stop operation signal including switching device identification information that uniquely identifies the switching device 10 is transmitted to one of the multiple switching devices 10, and then, without waiting for a response signal to the transmitted third stop operation signal to be received, the third stop operation signal including the switching device identification information that uniquely identifies the switching device 10 is transmitted to the next switching device 10. This process is repeated until the third stop operation signal is transmitted to all of the multiple switching devices 10. However, without being limited to this, for example, the third stop operation signal including reception code information (for example, reception code information indicating a reception identification code common to each of the multiple switching devices 10) that enables each of the multiple switching devices 10 to receive the third stop operation signal may be transmitted once, thereby simultaneously transmitting the third stop operation signal to the multiple switching devices 10.

[0110] As an example, a third stop operation signal including opening / closing device identification information that uniquely identifies the first opening / closing device 10a may be sent to the first opening / closing device 10a, and then, without waiting for a response signal to be received in response to the sent third stop operation signal, a third stop operation signal including opening / closing device identification information that uniquely identifies the second opening / closing device 10b may be sent to both the first opening / closing device 10a and the second opening / closing device 10b.

[0111] In addition, the opening / closing device identification information included in each of the second stop operation signal and the third stop operation signal may be included, for example, by the relay unit 84a of the relay device 80 based on the opening / closing device identification information stored in the relay side memory unit 85 when transmitted from the relay device 80.

[0112] In this case, in embodiment 1, when the opening / closing control unit 74a of each of the multiple opening / closing devices 10 receives the second stop operation signal or the third stop operation signal, it stops the opening / closing movement of the opening / closing body 40 based on the second stop operation signal or the third stop operation signal, and transmits a response signal to the received second stop operation signal or the third stop operation signal (note that when the third stop operation signal is received, the transmission of the response signal to the third stop operation signal may be omitted).

[0113] By this relay process, in the reserved state, the stop operation signal can be transmitted with priority over the reserved operation signal. Therefore, the opening / closing movement of at least one opening / closing body 40 of the multiple opening / closing devices 10 can be quickly stopped, making it easier to ensure safety when using the multiple opening / closing devices 10.

[0114] (Effects of the First Embodiment) As described above, according to the first embodiment, when a stop operation signal is received in the hold state, the relay device 80 includes the relay unit 84a that prioritizes the received stop operation signal over the held operation signal and transmits the received stop operation signal to at least one of the multiple opening / closing devices 10. Therefore, in the hold state, the stop operation signal can be transmitted with priority over the held operation signal. Therefore, the opening / closing movement of the opening / closing body 40 of at least one of the multiple opening / closing devices 10 can be quickly stopped, making it easier to ensure safety when using the multiple opening / closing devices 10.

[0115] Furthermore, when a stop operation signal is received in a pending state, the relay unit 84a discards the pending operation signal, so that it is possible to avoid moving the opening / closing body 40 to open or close based on the pending operation signal after the received stop operation signal has been sent with priority, making it easier to ensure safety when using multiple opening / closing devices 10.

[0116] Second Embodiment Next, a control system according to a second embodiment will be described. In this second embodiment, a relay device discards only operation signals other than a stop operation signal among the operation signals that are being held. However, the configuration and processing according to the second embodiment are the same as those according to the first embodiment unless otherwise specified, and the same configuration and processing will not be described again by using the same names or symbols as those used in the first embodiment as necessary.

[0117] (composition) First, the configuration of a control system 1 according to the second embodiment will be described.

[0118] The control system 1 according to the second embodiment has substantially the same configuration as the control system 1 according to the first embodiment.

[0119] (Relay processing) Next, the relay process will be described.

[0120] As for the relay processing according to the second embodiment, the processing from SB1 to SB4 in FIG. 5 is the same as the processing from SA1 to SA4 in FIG. 4, and therefore a description of the processing from SB1 to SB4 in FIG. 5 will be omitted.

[0121] As shown in FIG. 5, at SB5, the relay unit 84a of the relay device 80 discards the operation signal that has been held.

[0122] The method for discarding these operation signals is arbitrary, but in embodiment 2, only operation signals other than stop operation signals (specifically, the first stop operation signal, the second stop operation signal, and the third stop operation signal) are discarded among the reserved operation signals.

[0123] Specifically, among the operation signals stored in the relay side storage unit 85 during the processing of SB5, all open signals and close signals are deleted and discarded.

[0124] By such processing of SB5, for example, the opening / closing movement of the opening / closing bodies 40 of some of the opening / closing devices 10 can be reliably stopped based on the reserved stop operation signal, thereby ensuring the safety of those some of the opening / closing devices 10. Furthermore, the opening / closing movement of the opening / closing bodies 40 of the other some of the opening / closing devices 10 can be quickly stopped based on the received stop operation signal, making it easier to ensure the safety of those other some of the opening / closing devices 10.

[0125] In SB6, the relay unit 84a of the relay device 80 transmits the stop operation signal received in SB3 or / and the stop operation signal that was not discarded in SB5 to at least one of the multiple opening and closing devices 10, and / or receives a response signal to the transmitted stop operation signal from at least one of the multiple opening and closing devices 10. Thereafter, the process proceeds to SB1, and similarly thereafter, the processes from SB1 to SB6 are repeated.

[0126] Here, the method for transmitting the stop operation signal is arbitrary, but in the second embodiment, after all stop operation signals that have not been discarded by SB5 have been transmitted, the stop operation signal received by SB3 is transmitted.

[0127] This allows the stop operation signal that has not been discarded by SB5 to be transmitted with priority, and the opening / closing movement of at least one opening / closing body 40 of the multiple opening / closing devices 10 corresponding to the stop operation signal can be quickly stopped.

[0128] However, this is not limited to this, and for example, after transmitting the stop operation signal received by SB3, all stop operation signals that have not been discarded by SB5 may be transmitted (i.e., the stop operation signal received most recently may be given priority over the pending stop operation signal and transmitted to at least one of the multiple opening and closing devices 10).

[0129] This allows the stop operation signal received by SB3 to be transmitted with priority, and the opening / closing movement of at least one opening / closing body 40 of the plurality of opening / closing devices 10 corresponding to the stop operation signal can be quickly stopped.

[0130] By such relay processing, in the reserved state, the stop operation signal can be transmitted with priority over at least some of the reserved operation signals (specifically, the open signal and / or the close signal). Therefore, the opening / closing movement of at least one opening / closing body 40 of the multiple opening / closing devices 10 can be quickly stopped, making it easier to ensure safety when using the multiple opening / closing devices 10.

[0131] (Effects of the second embodiment) As described above, according to the second embodiment, when a stop operation signal is received in a reserved state, if the reserved operation signals include a stop operation signal, the relay unit 84a discards only the operation signals other than the stop operation signal among the reserved operation signals, so that, for example, the opening / closing movement of the opening / closing bodies 40 of some opening / closing devices 10 can be reliably stopped based on the reserved stop operation signal, ensuring the safety of some of the opening / closing devices 10. Furthermore, the opening / closing movement of the opening / closing bodies 40 of other opening / closing devices 10 can be quickly stopped based on the received stop operation signal, making it easier to ensure the safety of some of the opening / closing devices 10.

[0132] Third Embodiment Next, a control system according to a third embodiment will be described. In this third embodiment, a relay device 80 discards only operation signals that contain switching device identification information that matches the switching device identification information contained in the received stop operation signal, among the operation signals that are being held. However, the configuration and processing according to the third embodiment are the same as those according to the first embodiment unless otherwise specified, and the same configuration and processing will not be described again by using the same names or symbols as those used in the first embodiment as necessary.

[0133] (composition) First, the configuration of a control system 1 according to the third embodiment will be described.

[0134] The control system 1 according to the third embodiment has substantially the same configuration as the control system 1 according to the first embodiment.

[0135] (Relay processing) Next, the relay process will be described.

[0136] As for the relay processing according to the third embodiment, the processing from SC1 to SC3 in FIG. 6 is the same as the processing from SA1 to SA3 in FIG. 4, and therefore a description of the processing from SC1 to SC3 in FIG. 6 will be omitted.

[0137] As shown in FIG. 6, in SC4, the relay unit 84a of the relay device 80 determines whether or not the call is in a hold state.

[0138] Then, if the relay unit 84a of the relay device 80 determines that the call is in a hold state (SC4, Yes), it proceeds to SC5, and if it determines that the call is not in a hold state (SC4, No), it proceeds to SC8.

[0139] At SC5, the relay unit 84a of the relay device 80 discards the operation signal that has been held.

[0140] The method for discarding this operation signal is arbitrary, but in embodiment 3, when a stop operation signal is received in a pending state, only the operation signals on hold that contain opening / closing device identification information that matches the opening / closing device identification information contained in the received stop operation signal are discarded.

[0141] Specifically, when the stop operation signal received by SC3 is the first stop operation signal, only the operation signals that include the opening / closing device identification information contained in the first stop operation signal, which uniquely identifies a specific opening / closing device 10, are discarded from among the pending operation signals.

[0142] As an example, if the opening / closing device identification information included in the first stop operation signal is opening / closing device identification information that uniquely identifies the first opening / closing device 10a, and the pending operation signals include an open signal that includes opening / closing device identification information that uniquely identifies the first opening / closing device 10a, and an open signal and a close signal that include opening / closing device identification information that uniquely identifies the second opening / closing device 10b, only the open signal that includes opening / closing device identification information that uniquely identifies the first opening / closing device 10a may be discarded.

[0143] Furthermore, if the stop operation signal received by SC3 is the second stop operation signal (or the third stop operation signal), only the operation signals that include the opening and closing device identification information contained in the second stop operation signal (or the third stop operation signal) and that uniquely identifies each of the multiple opening and closing devices 10 are discarded among the pending operation signals.

[0144] As an example, if the opening / closing device identification information included in the second stop operation signal (or the third stop operation signal) is opening / closing device identification information that uniquely identifies each of the first opening / closing device 10a and the second opening / closing device 10b, and the reserved operation signals include an open signal that includes opening / closing device identification information that uniquely identifies the first opening / closing device 10a, and an open signal and a close signal that include opening / closing device identification information that uniquely identifies the second opening / closing device 10b, all of the reserved operation signals may be discarded.

[0145] By such processing by SC5, for example, it is possible to reliably perform the opening / closing movement of the opening / closing bodies 40 of some of the opening / closing devices 10 or stop the opening / closing movement based on an operation signal that includes opening / closing device identification information that does not match the opening / closing device identification information included in the received stop operation signal among the reserved operation signals, thereby maintaining the usability of those some of the opening / closing devices 10. Furthermore, it is possible to quickly stop the opening / closing movement of the opening / closing bodies 40 of other some of the opening / closing devices 10 based on the received stop operation signal, making it easier to ensure the safety of those other some of the opening / closing devices 10.

[0146] At SC6, the relay unit 84a of the relay device 80 determines whether or not any operation signals that were not discarded at SC5 remain among the reserved operation signals.

[0147] The method for determining whether or not this operation signal remains is arbitrary, but in embodiment 3, the determination is made based on whether or not the operation signal reserved in the relay side memory unit 85 of the relay device 80 is stored, and if the operation signal is stored, it is determined that the operation signal remains, and if the operation signal is not stored, it is determined that the operation signal does not remain.

[0148] Then, if the relay unit 84a of the relay device 80 determines that the above-mentioned operation signal remains (SC6, Yes), it proceeds to SC7, and if it determines that the above-mentioned operation signal does not remain (SC6, No), it proceeds to SC8.

[0149] In SC7, the relay unit 84a of the relay device 80 uses a method similar to the transmission method used in the processing of SA2 or SA6 to transmit the operation signal determined to remain in SA6 to at least one of the multiple opening and closing devices 10, and / or receives a response signal to the transmitted operation signal from at least one of the multiple opening and closing devices 10.

[0150] In SC8, the relay unit 84a of the relay device 80 uses a method similar to the transmission method of the process in SA6 to transmit the stop operation signal received in SC3 to at least one of the multiple switching devices 10, and / or receives a response signal to the transmitted stop operation signal from at least one of the multiple switching devices 10. Thereafter, the process proceeds to SC1, and similarly thereafter, the processes from SC1 to SC8 are repeated.

[0151] By such relay processing, in the reserved state, the stop operation signal can be transmitted with priority over at least some of the reserved operation signals (specifically, operation signals including opening / closing device identification information that matches the opening / closing device identification information included in the stop operation signal received by SC3). Therefore, the opening / closing movement of at least one opening / closing body 40 of the multiple opening / closing devices 10 can be quickly stopped, making it easier to ensure safety when using the multiple opening / closing devices 10.

[0152] (Effects of the Third Embodiment) As described above, according to the third embodiment, when a stop operation signal is received in the pending state, the relay unit 84a discards only those operation signals among the pending operation signals that include opening / closing device identification information that matches the opening / closing device identification information included in the received stop operation signal. Therefore, for example, it is possible to reliably perform opening / closing movement of the opening / closing bodies 40 of some opening / closing devices 10 or stop the opening / closing movement based on operation signals among the pending operation signals that include opening / closing device identification information that does not match the opening / closing device identification information included in the received stop operation signal, thereby maintaining the usability of some of the opening / closing devices 10. Furthermore, it is possible to quickly stop the opening / closing movement of the opening / closing bodies 40 of other opening / closing devices 10 based on the received stop operation signal, making it easier to ensure the safety of other some of the opening / closing devices 10.
