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. [Prior art documents] [Patent documents]

[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 conventional system, as described above, an open signal or the like transmitted from a mobile communication terminal is received by a corresponding transceiver handset via a base transceiver unit, and the open / close control of the shutter curtain of the electric shutter device provided in the transceiver handset is performed based on the open signal or the like received by the transceiver handset. Therefore, for example, when stopping the opening / closing movement of the shutter curtains of multiple electric shutter devices, a user operates multiple stop buttons on the mobile communication terminal, which causes multiple stop signals to be transmitted from the mobile communication terminal, and these transmitted stop signals are received by the multiple transceivers via the base transceiver unit, which may make it difficult to quickly perform emergency opening / closing movement of the opening / closing bodies or stop the opening / closing movement of the opening / closing bodies in multiple opening / closing devices. Therefore, there is room for improvement in terms of improving the usability of the system.

[0005] The present invention has been made to solve the above-mentioned problems in the conventional technology, and has an object to provide a control system and a relay device that can improve the usability of the control system. [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 a plurality of openings of a building, and a relay device capable of communicating with the plurality of opening / closing devices, the relay device 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 to open or close based on the operation signal, the operation signal includes an emergency operation signal for urgently opening or closing the opening / closing movement of the opening / closing body and / or stopping the opening / closing movement, and the relay device comprises relay means that transmits the emergency operation signal to the plurality of opening / closing devices when the emergency operation signal is received from the operating device or a predetermined operation is accepted. When the emergency operation signal is received from the operation device in a hold state in which the operation signals other than the emergency operation signal received from the operation device are held, the relay means discards all of the held operation signals and then transmits the emergency operation signal to the plurality of opening and closing devices.

[0007] The control system described in claim 2 is the control system described in claim 1, wherein when the emergency operation signal is received from the operating device or the predetermined operation is accepted, the relay means sequentially transmits the emergency operation signal to the plurality of opening / closing devices regardless of whether or not response signals to the emergency operation signal have been received from the plurality of opening / closing devices.

[0008] The control system according to claim 3 is the control system according to claim 2, When the relay means receives the emergency operation signal from the operating device, the relay means repeats multiple times the sequential transmission of the emergency operation signal to the plurality of opening / closing devices.

[0009] The control system according to claim 4 is the control system according to claim 2 or 3, Each of the plurality of opening and closing devices is equipped with a transmitting means that, when receiving an operation signal other than the emergency operation signal, transmits the response signal to the operation signal, and, when receiving the emergency operation signal, does not transmit the response signal to the emergency operation signal.

[0010] The control system according to claim 5 comprises: Claim 1 In the control system described in The emergency operation signal includes reception code information that enables each of the plurality of opening and closing devices to receive the emergency operation signal, and when the emergency operation signal is received from the operation device or when the specified operation is accepted, the relay means transmits the emergency operation signal once, thereby enabling the emergency operation signal to be relayed to the plurality of opening and closing devices.

[Effects of the Invention]

[0013] A control system according to claim 1, and Claim 6 According to the relay device described in the above, when an emergency operation signal is received from an operating device or a predetermined operation is accepted, the relay device includes a relay means for transmitting an emergency operation signal to a plurality of opening / closing devices, and therefore the emergency operation signal can be quickly relayed to the plurality of opening / closing devices. Therefore, emergency opening / closing movements and / or stopping of the opening / closing movements of the opening / closing bodies can be quickly performed in the plurality of opening / closing devices, and the usability of the control system can be improved. Furthermore, when an emergency operation signal is received from an operating device in the hold state, the relay means discards all held operation signals and then transmits the emergency operation signal to the multiple opening / closing devices, so that the emergency operation signal can be relayed with priority in the hold state and the emergency operation signal can be relayed to the multiple opening / closing devices more quickly.Furthermore, since all held operation signals can be discarded, it is possible to avoid opening / closing movement of the opening / closing body and / or stopping of the opening / closing movement based on the operation signal after the opening / closing movement of the opening / closing body has been stopped urgently in the multiple opening / closing devices.

[0014] According to the control system of claim 2, when an emergency operation signal is received from the operating device or a predetermined operation is accepted, the relay means transmits the emergency operation signal sequentially to the plurality of opening / closing devices regardless of whether or not response signals to the emergency operation signal have been received from the plurality of opening / closing devices. Therefore, when the emergency operation signal is transmitted sequentially, the emergency operation signal can be quickly relayed to the plurality of opening / closing devices, and emergency opening / closing movement and / or stopping of the opening / closing movement of the opening / closing body can be quickly performed in the plurality of opening / closing devices.

[0015] According to the control system of claim 3, When an emergency operation signal is received from the operating device, the relay means repeats the sequential transmission of the emergency operation signal to the multiple opening / closing devices multiple times, thereby ensuring the relay of the emergency operation signal to the multiple opening / closing devices and increasing the reliability of the relay.

[0016] According to the control system of claim 4, Each of the plurality of opening and closing devices is provided with a transmitting means that, when it receives an operation signal other than an emergency operation signal, transmits a response signal to the operation signal, and, when it receives an emergency operation signal, does not transmit a response signal to the emergency operation signal. This makes it possible to avoid transmitting response signals unnecessarily, thereby improving the controllability of the opening and closing devices.

[0017] According to the control system of claim 5, When an emergency operation signal is received from the operating device or a specified operation is accepted, the relay means can relay the emergency operation signal to multiple opening / closing devices by transmitting the emergency operation signal once.Therefore, by transmitting the emergency operation signal once, it can be relayed to multiple opening / closing devices, and the emergency operation signal can be relayed to multiple opening / closing devices quickly and efficiently.

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.

[0021] [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.

[0022] 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.

[0023] 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.

[0024] 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.

[0025] 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.

[0026] Furthermore, the specific type of "operation signal" is arbitrary, but the concept includes, for example, an open signal, a close signal, a stop signal, and an emergency operation signal.

[0027] Of these, the "open signal" is a signal for moving the opening / closing body to open, the "close signal" is a signal for moving the opening / closing body to close, and the "stop signal" is a signal for stopping the opening / closing movement of the opening / closing body.

[0028] Furthermore, the "emergency operation signal" is a signal for urgently opening or closing the opening / closing body and / or stopping the opening / closing movement. This emergency operation signal is a concept that includes, for example, an emergency opening signal for urgently opening the opening / closing body, an emergency closing signal for urgently closing the opening / closing body, and an emergency stop signal for urgently stopping the opening / closing movement of the opening / closing body, but in the embodiment, it will be described as an emergency stop signal.

[0029] 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.

[0030] 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.

[0031] [II] Specific details of the embodiment Next, specific details of the embodiment will be described.

[0032] First Embodiment First, a description will be given of a control system according to embodiment 1. In this embodiment 1, a relay device sequentially transmits an emergency operation signal to a plurality of switching devices.

[0033] (composition) First, the configuration of the control system according to the first embodiment will be described.

[0034] 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).

[0035] 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.

[0036] (Configuration - Switchgear) First, the configuration of the multiple opening and closing devices 10 will be described.

[0037] 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.

[0038] 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).

[0039] 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."

[0040] (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.

[0041] (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).

[0042] (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.

[0043] 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.

[0044] 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.

[0045] 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.

[0046] (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.

[0047] (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.

[0048] (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.

[0049] (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).

[0050] 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., open signal, close signal, stop signal) is output to the opening / closing device 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 device 50, or the opening / closing movement of the opening / closing body 40 can be electrically stopped.

[0051] (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.

[0052] 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.

[0053] 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.

[0054] 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").

[0055] 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.

[0056] (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.

[0057] 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.

[0058] 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.

[0059] (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.

[0060] (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.

[0061] (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)).

[0062] (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.

[0063] (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).

[0064] As shown in FIG. 2, the opening / closing side control unit 74 conceptually includes a opening / closing control unit 74a and a transmitting unit 74b.

[0065] (Configuration - Switchgear - Switching control system - Switching control unit - Switching control section - Switching control section) 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 .

[0066] (Configuration - Switchgear - Switching control system - Switching control unit - Switching control section - Transmitter) The transmitting unit 74b is a transmitting means that, when it receives an operation signal other than an emergency operation signal (specifically, an emergency stop signal), transmits a response signal to the operation signal, and, when it receives an emergency operation signal, does not transmit a response signal to the operation signal.

[0067] Here, the "response signal" refers to a signal that includes information indicating that an operation signal has been received.

[0068] (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).

[0069] (Configuration - Relay device) Returning to FIG. 1, the configuration of relay device 80 will now be described.

[0070] 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.

[0071] 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.

[0072] Here, the method of transmitting an operation signal in the operating device is arbitrary, but in embodiment 1, when the user presses any of the multiple open buttons, multiple close buttons, or multiple 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, close signal, or stop signal including opening / closing device identification information that uniquely identifies the opening / closing device 10 corresponding to the pressed button) is transmitted.

[0073] (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.

[0074] (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).

[0075] (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.

[0076] (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, functionally and conceptually includes a relay unit 84a.

[0077] The relay unit 84a is a relay means that transmits an emergency operation signal to multiple opening and closing devices 10 when an emergency operation signal is received from the operating device or when a specified operation is accepted, and when an operation signal other than an emergency operation signal (specifically, an open signal, a close signal, or a stop signal) is received from the operating device, the relay unit 84a transmits the operation signal to one of the multiple opening and closing devices 10.

[0078] (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).

[0079] (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.

[0080] 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.

[0081] 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.

[0082] When the relay process is started, 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 an emergency operation signal (specifically, an open signal, a close signal, or a stop signal including opening / closing device identification information) has been received from the operation device.

[0083] 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 SA4.

[0084] 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 SA3 described below, the stored operation signal is erased.

[0085] In SA2, the relay unit 84a of the relay device 80 transmits the operation signal (specifically, an operation signal other than an emergency 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).

[0086] The received operation signal may be transmitted in any manner, but in the first embodiment, it is transmitted as follows.

[0087] That is, first, the relay unit 84a of the relay device 80 transmits the received operation signal to the plurality of opening / closing devices 10. Next, after receiving the transmitted operation signal, the opening / closing-side control unit 74 of each of the plurality of opening / closing devices 10 determines whether or not 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 deemed to have been transmitted to a specific opening / closing device 10, and the opening / closing control unit 74a of each of the plurality of opening / closing devices 10 performs opening / closing control of the opening / closing body 40 based on the received operation signal, and the transmitting unit 74b of each of the plurality of opening / closing devices 10 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 deemed not to have been transmitted to the specific opening / closing device 10, and the opening / closing control unit 74a of each of the multiple opening / closing devices 10 does not control the opening / closing of the opening / closing body 40 based on the received operation signal, and the transmitting unit 74b of each of the multiple opening / closing devices 10 does not transmit a response signal.

[0088] 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 because the opening / closing device identification information matches the opening / closing device identification information included in the received operation signal, and the transmitting unit 74b of the first opening / closing device 10a 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 operation signal because the opening / closing device identification information does not match the opening / closing device identification information included in the received operation signal, and the transmitting unit 74b of the second opening / closing device 10b does not transmit a response signal.

[0089] In this case, the specific processing contents of the opening and closing control of the opening and closing body 40 by the opening and closing control section 74a are arbitrary, but in the first embodiment, they are as follows.

[0090] That is, when a close signal or an open signal transmitted by SA2 is received, the opening / closing body 40 is electrically moved to close or open by the opening / closing device 50. Also, when the opening / closing body 40 is electrically moved to close or open, when a stop signal transmitted by SA2 is received, the opening / closing device 50 stops the closing or opening movement.

[0091] 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).

[0092] 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 open signal, a close signal, or a stop 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 stop signal received via the opening / closing-side operation unit 61 (that is, priority is given to the control of the open / closed state of the opening / closing body 40 based on the 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 an emergency operation signal transmitted by SA7, 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 open signal, a close signal, or a stop 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.

[0093] In SA3, the relay unit 84a of the relay device 80 determines whether or not a response signal (specifically, a response signal including the opening / closing device identification information) to the operation signal transmitted in SA2 has been received from the specific opening / closing device 10.

[0094] While the method for determining whether or not the response signal has been received is arbitrary, in the first embodiment, it is determined whether or not the switching device identification information included in the received response signal matches the switching device identification information included in the operation signal transmitted by 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. Furthermore, when the response signal is received, the operation signal stored in the relay-side memory unit 85 and corresponding to the response signal is erased.

[0095] Then, the relay unit 84a of the relay device 80 waits until the above-mentioned response signal is received (SA3, No), and if it is determined that the above-mentioned response signal has been received (SA3, Yes), it proceeds to SA1 (note that when the above-mentioned response signal is received, the operation signal stored in the relay side memory unit 85 and corresponding to the response signal is erased).

[0096] In SA4, the relay unit 84a of the relay device 80 determines whether or not the timing (hereinafter referred to as "transmission timing") to transmit an emergency operation signal (specifically, an emergency stop signal) has arrived.

[0097] The method for determining whether or not the transmission timing has arrived is arbitrary, but in the first embodiment, the determination is made based on whether or not an emergency operation signal has been received from the operation device or whether or not a predetermined operation has been accepted via the relay-side operation unit 81, and if an emergency operation signal has been received or a predetermined operation has been accepted, it is determined that the transmission timing has arrived, and if an emergency operation signal has not been received or a predetermined operation has not been accepted, it is determined that the transmission timing has not arrived.

[0098] The "predetermined operation" corresponds to, for example, pressing the setting button and / or other buttons on the relay side operation unit 81 a predetermined number of times and / or for a predetermined period of time.

[0099] Then, if the relay unit 84a of the relay device 80 determines that the transmission timing has arrived (SA4, Yes), it proceeds to SA5, and if it determines that the transmission timing has not arrived (SA4, No), it proceeds to SA1.

[0100] In SA5, the relay unit 84a of the relay device 80 determines whether the operation signal received in SA1 is in a reserved state (hereinafter referred to as a "reserved state").

[0101] Here, in embodiment 1, the "hold state" refers to a state 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, or / and the received operation signal has been transmitted but no response signal to the operation signal has been received, and therefore the operation signal remains in the relay side memory unit 85 of the relay device 80.

[0102] 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.

[0103] 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.

[0104] In the first embodiment, the processes from SA1 to SA3 are executed in parallel with the processes from SA4 to SA7 (described later). As a result, for example, a hold state may occur while the processes from SA1 to SA3 are executed in parallel. Furthermore, when a response signal is received at SA3 in the hold state, the processes from SA2 and SA3 are executed in parallel, so that the relay unit 84a of the relay device 80 can transmit the operation signal remaining in the relay-side memory unit 85 to the specific opening / closing device 10 and can receive a response signal to the operation signal.

[0105] Furthermore, the method for determining whether or not the state is on hold is arbitrary, but in embodiment 1, during processing of SA4, the determination is made based on whether or not the operation signal received at SA1 remains in the relay side memory unit 85, and if the operation signal remains in the relay side memory unit 85, it is determined that the state is on hold, and if the operation signal does not remain in the relay side memory unit 85, it is determined that the state is not on hold.

[0106] Then, if the relay unit 84a of the relay device 80 determines that the call is in a hold state (SA5, Yes), it proceeds to SA6, and if the relay unit 84a determines that the call is not in a hold state (SA5, No), it proceeds to SA7.

[0107] In SA6, the relay unit 84a of the relay device 80 discards all of the operation signals that are on hold.

[0108] The method for discarding the operation signals is arbitrary, but for example, the operation signals are discarded by deleting all the operation signals remaining in the relay side storage unit 85 during the processing of SA6.

[0109] In SA7, the relay unit 84a of the relay device 80 transmits the emergency operation signal to the plurality of switching devices 10, and then proceeds to SA1, and thereafter similarly repeats the processes from SA1 to SA7.

[0110] The method for transmitting this emergency operation signal is arbitrary, but in embodiment 1, regardless of whether or not response signals to the emergency operation signal have been received from the multiple opening / closing devices 10, the emergency operation signal is transmitted sequentially to the multiple opening / closing devices 10, and the sequential transmission is repeated multiple times (for example, about two to five times).

[0111] Specifically, after transmitting an emergency operation signal including switching device identification information that uniquely identifies the switching device 10 to one of the multiple switching devices 10, the process of transmitting an emergency operation signal including switching device identification information that uniquely identifies the switching device 10 to the next switching device 10 without waiting for a response signal to the transmitted emergency operation signal to be received is repeated until emergency operation signals are transmitted to all of the multiple switching devices 10 (specifically, the multiple switching devices 10 corresponding to the multiple switching device identification information registered in the relay side memory unit 85), and this repeated process is repeated multiple times.

[0112] In addition, the opening / closing device identification information included in the emergency 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.

[0113] As an example, an emergency operation signal including switching device identification information that uniquely identifies the first switching device 10a may be sent to the first switching device 10a, and then, without waiting for a response signal to the transmitted emergency operation signal to be received, an emergency operation signal including switching device identification information that uniquely identifies the second switching device 10b may be sent to the second switching device 10b by repeating this process twice, so that an emergency operation signal may be transmitted to both the first switching device 10a and the second switching device 10b.

[0114] In this case, in the first embodiment, when an emergency operation signal is received, the opening / closing control unit 74a of each of the plurality of opening / closing devices 10 stops the opening / closing movement of the opening / closing body 40 based on the emergency operation signal. Furthermore, by configuring the transmitting unit 74b of each of the plurality of opening / closing devices 10 not to transmit a response signal in response to the received emergency operation signal, it is possible to avoid transmitting a response signal unnecessarily and to improve the controllability of the opening / closing device 10.

[0115] However, the present invention is not limited to this. For example, when the transmitter 74b of each of the plurality of opening and closing devices 10 receives an emergency operation signal, the transmitter 74b may transmit a response signal to the emergency operation signal.

[0116] By performing the processes from SA4 to SA7 as described above, when emergency operation signals are transmitted sequentially, the emergency operation signals can be quickly relayed to the multiple opening / closing devices 10, and the opening / closing movement of the opening / closing body 40 can be stopped quickly in the multiple opening / closing devices 10. Furthermore, emergency operation signals can be relayed with priority in the reserved state, and the emergency operation signals can be relayed to the multiple opening / closing devices 10 more quickly. Furthermore, all reserved operation signals can be discarded, and after the opening / closing movement of the opening / closing body 40 has been stopped urgently in the multiple opening / closing devices 10, it is possible to avoid the opening / closing movement and / or the stop of the opening / closing movement of the opening / closing body 40 being performed based on the operation signals. Furthermore, since the sequential transmission of emergency operation signals is repeated multiple times, the emergency operation signals can be reliably relayed to the multiple opening / closing devices 10, and the reliability of the relay can be improved.

[0117] Such relay processing enables rapid relay of emergency operation signals to the multiple opening / closing devices 10. Therefore, the opening / closing movement of the opening / closing body 40 in the multiple opening / closing devices 10 can be stopped quickly in an emergency, thereby improving the usability of the control system 1.

[0118] (Effects of the First Embodiment) As described above, according to the first embodiment, the relay device 80 includes the relay unit 84a that transmits the emergency operation signal to the plurality of opening / closing devices 10 when an emergency operation signal is received from the operating device or when a predetermined operation is accepted, and therefore can quickly relay the emergency operation signal to the plurality of opening / closing devices 10. Therefore, the opening / closing movement of the opening / closing body 40 can be quickly stopped in an emergency in the plurality of opening / closing devices 10, and the usability of the control system 1 can be improved.

[0119] Furthermore, when an emergency operation signal is received from the operating device or a specified operation is accepted, the relay unit 84a transmits the emergency operation signal sequentially to the multiple opening / closing devices 10 regardless of whether a response signal to the emergency operation signal has been received from the multiple opening / closing devices 10. Therefore, when the emergency operation signal is transmitted sequentially, the emergency operation signal can be quickly relayed to the multiple opening / closing devices 10, and the opening / closing movement of the opening / closing body 40 can be quickly stopped in the multiple opening / closing devices 10 in an emergency.

[0120] Furthermore, when an emergency operation signal is received from an operating device in the hold state, the relay unit 84a discards all held operation signals and then transmits the emergency operation signal sequentially to the plurality of opening / closing devices 10, so that the emergency operation signal can be relayed with priority in the hold state and the emergency operation signal can be relayed more quickly to the plurality of opening / closing devices 10. Furthermore, all held operation signals can be discarded, and after the opening / closing movement of the opening / closing body 40 has been urgently stopped in the plurality of opening / closing devices 10, it is possible to avoid opening / closing movement and / or stopping of the opening / closing movement of the opening / closing body 40 based on the operation signal.

[0121] Furthermore, when an emergency operation signal is received from the operating device, the relay unit 84a repeats the sequential transmission of the emergency operation signal to the multiple opening / closing devices 10 multiple times, thereby ensuring reliable relay of the emergency operation signal to the multiple opening / closing devices 10 and increasing the reliability of the relay.

[0122] Furthermore, each of the plurality of opening and closing devices 10 is provided with a transmitting unit 74b that, when it receives an operation signal other than an emergency operation signal, transmits a response signal to the operation signal, and, when it receives an emergency operation signal, does not transmit a response signal to the emergency operation signal. This makes it possible to avoid transmitting response signals unnecessarily, thereby improving the controllability of the opening and closing devices 10.

[0123] Second Embodiment Next, a control system according to a second embodiment will be described. In this second embodiment, a relay device transmits an emergency operation signal once. 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 be omitted from description by using the same names or symbols as those used in the first embodiment as necessary.

[0124] (composition) First, the configuration of a control system 1 according to the second embodiment will be described.

[0125] The control system 1 according to the second embodiment has substantially the same configuration as the control system 1 according to the first embodiment.

[0126] (Relay processing) Next, the relay process will be described.

[0127] The relay processing according to the second embodiment is similar to the processing from SA1 to SA6 in FIG. 4, and therefore will not be illustrated or described.

[0128] As shown in FIG. 4, in SA7, the relay unit 84a of the relay device 80 transmits an emergency operation signal to the plurality of switching devices 10, and then proceeds to SA1, and thereafter similarly repeats the processes from SA1 to SA7.

[0129] The method for transmitting this emergency operation signal is arbitrary, but in embodiment 2, by transmitting an emergency operation signal once that includes reception code information (for example, reception code information indicating an identification code for reception common to each of the multiple opening and closing devices 10) that enables each of the multiple opening and closing devices 10 to receive the emergency operation signal, the emergency operation signal can be relayed to the multiple opening and closing devices 10.

[0130] The reception code information included in the emergency operation signal may be included, for example, when it is transmitted from the relay device 80 by the relay unit 84a of the relay device 80, or may be included when it is transmitted from the operation device by the control unit of the operation device.

[0131] As an example, the emergency operation signal may be relayed to the first opening / closing device 10a and the second opening / closing device 10b by transmitting an emergency operation signal once, the emergency operation signal including reception code information that enables each of the first opening / closing device 10a and the second opening / closing device 10b to receive the emergency operation signal.

[0132] By performing such processing at SA7, an emergency operation signal can be transmitted once and relayed to a plurality of switching devices 10, and the emergency operation signal can be relayed to a plurality of switching devices 10 quickly and efficiently.

[0133] Furthermore, by such relay processing, similar to the relay processing according to the first embodiment, it is possible to quickly relay emergency operation signals to the plurality of opening and closing devices 10. Therefore, it is possible to quickly stop the opening and closing movement of the opening and closing body 40 in the plurality of opening and closing devices 10 in an emergency, and it is possible to improve the usability of the control system 1.

[0134] (Effects of the second embodiment) Thus, according to the second embodiment, when an emergency operation signal is received from an operating device or a predetermined operation is accepted, the relay unit 84a can relay the emergency operation signal to a plurality of opening / closing devices 10 by transmitting the emergency operation signal once. Therefore, the emergency operation signal can be relayed to a plurality of opening / closing devices 10 by transmitting the emergency operation signal once, and the emergency operation signal can be relayed to a plurality of opening / closing devices 10 quickly and efficiently.

[0135] [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 set forth in the claims. Such modifications will be described below.

[0136] (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.

[0137] (Regarding decentralization and integration) Furthermore, the electrical components described above are merely functional concepts and do not necessarily need to be physically configured as illustrated. In other words, the specific form of distribution or integration of each component is not limited to that illustrated, and all or part of the components can be functionally or physically distributed or integrated in any unit depending on various loads, usage conditions, etc. Furthermore, the term "device" in this application is not limited to a single device but also includes a plurality of devices. For example, the relay device 80 according to the first embodiment may be distributed among multiple devices configured to be able to communicate with each other, with a relay-side control unit 84 provided in some of the devices and a relay-side memory unit 85 provided in another of the devices.

[0138] (shape, numbers, 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 in terms of shape, numerical value, or the structure or chronological relationship of multiple components.

[0139] (Regarding the opening and closing device) In the above-described first and second embodiments, the number of opening and closing devices 10 installed is two, but the number is not limited to this, and may be, for example, three or more.

[0140] Furthermore, in the first and second embodiments, the opening and closing device 10 is described as including the transmitting unit 74b, but this is not limiting, and for example, the transmitting unit 74b may be omitted.

[0141] (About the obstacle detection section) In the above first and second embodiments, the obstacle detection unit 64 is described as being configured using an overload detection sensor, but is not limited to this and may be, for example, a seat panel switch provided on the seat panel 42.

[0142] (Regarding emergency operation signals) In the above-described first and second embodiments, the emergency operation signal is described as an emergency stop signal. However, the emergency operation signal is not limited to this. For example, the emergency operation signal may be an emergency open signal or an emergency close signal. Alternatively, the emergency operation signal may be any one of an emergency stop signal, an emergency open signal, or an emergency close signal selected by a user's operation on an operating device. In this case, for example, when the opening / closing control unit 74a of each of the multiple opening / closing devices 10 receives an emergency open signal or an emergency close signal, the opening / closing control unit 74a may open or close the opening / closing body 40 based on the emergency open signal or emergency close signal. This allows the opening / closing body 40 of the multiple opening / closing devices 10 to be opened or closed quickly in an emergency, thereby improving the usability of the control system 1.

[0143] (About relay processing) In the above-described first embodiment, when an emergency operation signal is received from an operating device in the hold state, the relay unit 84a of the relay device 80 discards all of the held operation signals and then sequentially transmits the emergency operation signals to the plurality of opening / closing devices 10. However, this is not limited to this. For example, the held operation signals may be transmitted first and prioritized without being discarded, and then the held operation signals may be transmitted. Alternatively, the held operation signals may be transmitted first and prioritized without being discarded, and then the emergency operation signals may be transmitted sequentially to the plurality of opening / closing devices 10.

[0144] In the second embodiment, when an emergency operation signal is received from an operating device in the hold state, the relay unit 84a of the relay device 80 discards all the held operation signals and then transmits the emergency operation signal once. However, this is not limited to this. For example, the held operation signals may be transmitted after the emergency operation signal has been given priority without being discarded. Alternatively, the held operation signals may be transmitted after the emergency operation signal has been given priority without being discarded and then the emergency operation signal has been transmitted once.

[0145] Furthermore, in the above-described first embodiment, it has been explained that when an emergency operation signal is received from an operating device, the relay unit 84a of the relay device 80 repeats the sequential transmission of the emergency operation signal to the plurality of opening / closing devices 10 multiple times. However, this is not limiting, and for example, the sequential transmission of the emergency operation signal to the plurality of opening / closing devices 10 may be performed only once.

[0146] In addition, in the above-described second embodiment, the relay unit 84a of the relay device 80 transmits the emergency operation signal only once when the emergency operation signal is received from the operation device, but this is not limiting, and for example, the relay unit 84a may transmit multiple emergency operation signals.

[0147] In the above-described first and second embodiments, the relay unit 84a of the relay device 80 does not determine whether or not a transmission timing has arrived while waiting for a response signal in SA3, but this is not limiting. For example, the relay unit 84a may determine whether or not a transmission timing has arrived while waiting for reception of a response signal in SA3, and if the transmission timing has arrived, the process may proceed to SA5.

[0148] In the above-described first and second embodiments, the process proceeds to SA1 after the process of SA7, and the relay unit 84a of the relay device 80 becomes able to receive an operation signal from the operating device. However, this is not limited to this. For example, after the process of SA7, the relay unit 84a of the relay device 80 may wait until a predetermined time (e.g., about 3 to 5 minutes) has elapsed, and may proceed to SA1 after the predetermined time has elapsed. In other words, the relay unit 84a may not receive an operation signal transmitted from the operating device until the predetermined time has elapsed after transmitting the emergency operation signal.

[0153] The control system of Supplementary Note 5 is the control system described in any one of Supplementary Notes 2 to 4, wherein each of the plurality of opening and closing devices is provided with a transmitting means that, when receiving an operation signal other than the emergency operation signal, transmits the response signal to the operation signal, and, when receiving the emergency operation signal, does not transmit the response signal to the emergency operation signal.

[0154] The control system of Supplementary Note 6 is the control system described in Supplementary Note 1, wherein the emergency operation signal includes reception code information for enabling each of the plurality of opening / closing devices to receive the emergency operation signal, and when the emergency operation signal is received from the operation device or the predetermined operation is accepted, the relay means transmits the emergency operation signal once, thereby enabling the emergency operation signal to be relayed to the plurality of opening / closing devices.

[0155] The relay device of Supplementary Note 7 is a relay device capable of communicating with a plurality of opening / closing devices provided at each of a plurality of openings in a building, each of which has an opening / closing body that opens and closes the opening, and which relays an operation signal received from an operating device that operates the opening / closing device to the plurality of opening / closing devices, the operation signal including an emergency operation signal for urgently opening or closing the opening / closing body and / or stopping the opening / closing movement, and which is equipped with relay means that transmits the emergency operation signal to the plurality of opening / closing devices when the emergency operation signal is received from the operating device or when a predetermined operation is accepted.

[0156] (Effect of supplementary notes) According to the control system described in Supplementary Note 1 and the relay device described in Supplementary Note 7, the relay device includes relay means for transmitting an emergency operation signal to a plurality of opening / closing devices when an emergency operation signal is received from the operating device or a predetermined operation is accepted, so that the emergency operation signal can be quickly relayed to the plurality of opening / closing devices. Therefore, emergency opening / closing movements and / or stopping of the opening / closing movements of the opening / closing bodies can be quickly performed in the plurality of opening / closing devices, and usability of the control system can be improved.

[0157] According to the control system described in Appendix 2, when an emergency operation signal is received from the operating device or a predetermined operation is accepted, the relay means transmits the emergency operation signal sequentially to the multiple opening / closing devices regardless of whether response signals to the emergency operation signal have been received from the multiple opening / closing devices. Therefore, when the emergency operation signal is transmitted sequentially, the emergency operation signal can be quickly relayed to the multiple opening / closing devices, and emergency opening / closing movement and / or stopping of the opening / closing movement of the opening / closing body can be quickly performed in the multiple opening / closing devices.

[0158] According to the control system described in Supplementary Note 3, when an emergency operation signal is received from an operating device in the hold state, the relay means discards all held operation signals and then transmits the emergency operation signal sequentially to the multiple opening / closing devices, so that the emergency operation signal can be relayed with priority in the hold state and the emergency operation signal can be relayed to the multiple opening / closing devices more quickly. Furthermore, since all held operation signals can be discarded, it is possible to avoid opening / closing movement of the opening / closing body and / or stopping of the opening / closing movement based on the operation signal after the opening / closing movement of the opening / closing body has been urgently stopped in the multiple opening / closing devices.

[0159] According to the control system described in Supplementary Note 4, when an emergency operation signal is received from the operating device, the relay means repeats multiple times the sequential transmission of the emergency operation signal to the multiple opening / closing devices, thereby ensuring the relay of the emergency operation signal to the multiple opening / closing devices and increasing the reliability of the relay.

[0160] According to the control system described in Supplementary Note 5, each of the plurality of opening and closing devices is provided with a transmitting means that, when it receives an operation signal other than an emergency operation signal, it transmits a response signal to the operation signal, and, when it receives an emergency operation signal, it does not transmit a response signal to the emergency operation signal. Therefore, it is possible to avoid transmitting response signals unnecessarily and to improve the controllability of the opening and closing devices.

[0161] According to the control system described in Supplementary Note 6, when an emergency operation signal is received from the operating device or a predetermined operation is accepted, the relay means can relay the emergency operation signal to multiple opening / closing devices by transmitting the emergency operation signal once. Therefore, the emergency operation signal can be relayed to multiple opening / closing devices by transmitting it once, and the emergency operation signal can be relayed to multiple opening / closing devices quickly and efficiently.
