Description

[Technical field]

[0001] The present invention relates to a control system and method for a watertight device that closes openings such as entrances and exits of buildings such as buildings, factories, warehouses, garages, etc., or openings such as entrances and exits of subway stations and underground shopping malls in a watertight state during heavy rainfall, and in particular to a control system and method for a watertight opening and closing device that is suitable for controlling a watertight opening and closing device configured using an opening and closing body such as a shutter. [Background technology]

[0002] 2. Description of the Related Art Water stop devices are installed at ground level entrances to underground facilities such as subway stations and underground shopping malls, as well as at building entrances, to prevent water from heavy rain or other events from flowing into the underground facilities or inside the buildings. An example of such a water shutoff device is a sealed opening and closing device described in Patent Document 1. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2015-110866 A Summary of the Invention [Problem to be solved by the invention]

[0004] When the water stop device is a water stop opening / closing body device constructed using a water stop opening / closing body such as a shutter, conventional water stop opening / closing body devices are operated using an operating switch such as a push button switch located near the water stop opening / closing body, and even in a dangerous condition such as flooding, the water stop opening / closing body cannot be operated unless one goes close to it. Furthermore, even if the operating switch for the watertight opening / closing body is installed in a remote location and the operation of the watertight opening / closing body is controlled remotely, it is not possible to determine whether the water can be released from the watertight state unless the state of flooding is confirmed.In addition, since it is not possible to confirm whether there are obstacles such as people or objects near the watertight opening / closing body, for example, there are cases where a person passes under the watertight opening / closing body while it is being lowered, interrupting the lowering of the watertight opening / closing body and preventing the water from being stopped.

[0005] The present invention has been made in consideration of the above-mentioned points, and aims to provide a control system and control method for a watertight opening and closing device that can safely and reliably control operation from a remote location while checking the flooding state, the presence or absence of obstacles, etc. [Means for solving the problem]

[0006] A first feature of the control system for a watertight opening and closing body device of the present invention is a control system for a watertight opening and closing body device having a watertight opening and closing means provided on the peripheral portion of the opening, an opening and closing machine for electrically operating the watertight opening and closing means, watertight means for making the watertight opening and closing means and the peripheral portion of the opening watertight and for releasing the watertight state between the watertight opening and closing means and the peripheral portion of the opening, and a control means for driving the opening and closing machine to electrically control the operation of the watertight opening and closing means and also to electrically control the operation of the watertight means, and the control system is provided with an image acquisition means for acquiring images of the surroundings of the watertight opening and closing means, an Internet connection means for connecting the image acquisition means and the control means to the Internet, and a remote control terminal for displaying images acquired by the image acquisition means via the Internet and remotely controlling the control means via the Internet, wherein the remote control terminal displays operation buttons for remote control and the control means operates in response to operation of the operation buttons displayed on the remote control terminal, and the operation buttons displayed on the remote control terminal do not include an operation button for instructing release of the watertight state provided by the watertight means, or there are restrictions on operation of the operation button.

[0007] Using an Internet connection means, the image acquisition means and the control means are connected to the Internet, and images of the surroundings of the water stop opening / closing means acquired by the image acquisition means are displayed on the remote control terminal via the Internet, and the control means is remotely controlled by the remote control terminal via the Internet, so that the operation of the water stop opening / closing means can be safely and reliably controlled from a remote location while checking the flooding state and the presence or absence of obstacles, etc. Then, operation buttons for remote control are displayed on the remote control terminal, and the control means is operated in accordance with the operation of the displayed operation buttons. The operation buttons displayed on the remote control terminal do not display an operation button for instructing the release of the watertight state provided by the watertight means, or the operation of the operation button is restricted, so there is no risk of the operation button for releasing the watertight state provided by the watertight means being operated erroneously, releasing the watertight state and causing flooding.

[0008] The watertight opening and closing means is composed of an opening and closing member such as a shutter curtain that electrically opens and closes an opening such as an entrance or window, or an internal passage or space in a structure such as a building, factory, warehouse, or garage. When the watertight opening and closing means is a shutter curtain, it is stored in the upper part, which is one of the peripheral parts of the opening of a building, etc., and the shutter curtain passes through a lintel or the like and descends to electrically open and close the opening. In addition, the watertight opening and closing means may be stored in the lower part of the opening and electrically open and close by a rising method, or the watertight opening and closing means may be stored in the side and electrically move by a sliding method. The watertight opening and closing means may include those that can fully close the opening by closing it and those that cannot.

[0009] A second feature of the control system for a watertight opening / closing body device of the present invention is that, in the control system for a watertight opening / closing body device described in the first feature, after an image of the surroundings of the watertight opening / closing means is displayed on the remote control terminal for a predetermined period of time, the restriction on the operation of the operating button for instructing the release of the watertight state provided by the watertight means is lifted. After an image of the surroundings of the watertight opening / closing means is displayed on the remote control terminal for a predetermined period of time, the restriction on the operation of the operation button for instructing the release of the watertight state of the watertight means is lifted and the operation of the operation button is enabled, thereby giving the operator an opportunity to check the environment around the watertight opening / closing means.

[0010] A third feature of the control system for a watertight opening / closing body device of the present invention is that, in the control system for a watertight opening / closing body device described in the first or second feature, the remote control terminal inquires as to whether or not an image of the surroundings of the watertight opening / closing means has been viewed, and after confirmation input has been made, restrictions on the operation of the operating button for instructing the release of the watertight state provided by the watertight means are lifted. The remote control terminal inquires whether the image around the watertight opening and closing means has been viewed, and after confirmation input, the restriction on the operation of the operation button for instructing the release of the watertight state by the watertight means is released, thereby preventing the release of the watertight state without checking the image around the watertight opening and closing means.

[0011] A fourth feature of the control system for a watertight opening / closing body device of the present invention is a control system for a watertight opening / closing body device having a watertight opening / closing means provided on the periphery of an opening, an opening / closing machine for electrically operating the watertight opening / closing means, a watertight means for making the watertight opening / closing means and the periphery of the opening watertight and releasing the watertight state between the watertight opening / closing means and the periphery of the opening, and a control means for driving the opening / closing machine to electrically control the operation of the watertight opening / closing means and to electrically control the operation of the watertight means, the control system including image acquisition means for acquiring an image of the surroundings of the watertight opening / closing means, internet connection means for connecting the image acquisition means and the control means to the internet, and a control means for acquiring an image of the surroundings of the watertight opening / closing means via the internet. The device comprises a remote control terminal which displays the image acquired by the acquisition means and remotely controls the control means via the Internet, the remote control terminal displays operation buttons for remote control, the control means operates in response to operation of the operation buttons displayed on the remote control terminal, and the operation buttons displayed on the remote control terminal include a first operation button for instructing the halt of operation of the watertight opening and closing means which is located in the center of the short side of the approximately rectangular remote control terminal, a second operation button for instructing the start of a watertight state by the watertight means, and a third operation button for instructing the release of the watertight state by the watertight means which are located to the left and right of the first operation button. A first button for instructing the halt of the operation of the watertight opening and closing means is located in the center of the short side of the approximately rectangular remote control terminal, and a second operation button for instructing the start of a watertight state by the watertight means and a third operation button for instructing the release of the watertight state by the watertight means are located to the left and right of the first operation button.Therefore, regardless of whether the approximately rectangular remote control terminal is held in the short side direction with the left or right hand, the operability of the first button remains the same, and the first button, which may require particular urgency, can be operated easily.

[0012] A fifth feature of the control system for a watertight opening / closing body device of the present invention is that, in the control system for a watertight opening / closing body device described in the fourth feature, when the second operating button or the third operating button is operated while the control means is performing the opening or closing operation of the watertight opening / closing means, the control means stops the operation of the watertight opening / closing means. When the second operation button or the third operation button is operated while the control means is opening or closing the water stop opening / closing means, the control means stops the operation of the water stop opening / closing means. Therefore, even if there is an erroneous operation of the second operation button or the third operation button instead of the first button, the water stop opening / closing means in operation can be stopped.

[0013] A first feature of the control method for a watertight opening / closing body device of the present invention is a control method for a watertight opening / closing body device having a watertight opening / closing means provided on the peripheral portion of an opening, an opening / closing machine for electrically operating the watertight opening / closing means, watertight means for making the watertight opening / closing means and the peripheral portion of the opening watertight and for releasing the watertight state between the watertight opening / closing means and the peripheral portion of the opening, and a control means for driving the opening / closing machine to electrically control the operation of the watertight opening / closing means and also to electrically control the operation of the watertight means, wherein an image acquisition means is provided for acquiring an image of the surroundings of the watertight opening / closing means, an Internet connection means is used to connect the image acquisition means and the control means to the Internet, the image acquired by the image acquisition means is displayed on a remote control terminal via the Internet, and the control means is remotely controlled via the Internet by the remote control terminal, operation buttons for remote control are displayed on the remote control terminal, the control means is operated in response to operation of the displayed operation buttons, and the operation buttons displayed on the remote control terminal do not display an operation button for instructing release of the watertight state provided by the watertight means, or operation of the operation button is restricted. This is a control method for a watertight opening / closing device, which corresponds to the control system for a watertight opening / closing device described in the first aspect.

[0014] A second feature of the control method for a watertight opening / closing body device of the present invention is that, in the control method for a watertight opening / closing body device described in the first feature, after an image of the surroundings of the watertight opening / closing means is displayed on a remote control terminal for a predetermined period of time, the restriction on the operation of the operating button for instructing the release of the watertight state provided by the watertight means is lifted. This is a control method for a watertight opening / closing device, which corresponds to the control system for a watertight opening / closing device described in the second aspect.

[0015] A third feature of the control method for a watertight opening / closing body device of the present invention is that, in the control method for a watertight opening / closing body device described in the first or second feature, the remote control terminal inquires as to whether or not an image of the surroundings of the watertight opening / closing means has been viewed, and after confirmation input is received, the restriction on operation of the operating button for instructing the release of the watertight state provided by the watertight means is lifted. This is a control method for a watertight opening / closing device, which corresponds to the control system for a watertight opening / closing device described in the third aspect.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0020] A preferred embodiment of a control system and method for a watertight opening / closing body device according to the present invention will be described below with reference to the attached drawings. In this embodiment, a watertight shutter device equipped with a shutter curtain that opens and closes vertically will be described as an example of a watertight opening / closing means for stopping water. Fig. 1 is a diagram showing the schematic configuration of a watertight shutter device which is a watertight opening / closing body device according to one embodiment of the present invention. In Fig. 1, a watertight opening / closing body device 10 is a watertight shutter device that opens and closes an opening vertically.

[0021] The watertight opening / closing body device may be a panel shutter device in which a panel-shaped opening / closing body is opened and closed vertically, as described in, for example, JP-A-2000-73469.

[0022] The watertight opening / closing device 10 is installed in openings of structures such as buildings, or openings such as entrances and exits of subway stations and underground shopping malls, and basically comprises a shutter case 11, a shutter curtain 12, a watertight plate 12a, guide rails 13, 14, a winding shaft 15, a chain 16, a motor 17, an interlocking repeater 19, a watertight device 20, a shutter control panel 30, an IoT control panel 40, and a surveillance camera 50.

[0023] The guide rails 13, 14 are provided on both ends of an opening in a building or other structure so as to contact both ends of the shutter curtain 12, and are made of a metal member or an equivalent member having a guide groove with a U-shaped cross section that spans from the lintel to the floor. The shutter curtain 12 rises and falls along the guide grooves of the guide rails 13, 14 to open and close.

[0024] A water stop plate 12a of a predetermined height is attached to the lower part of the shutter curtain 12. This water stop plate 12a and the guide rails 13, 14 are made watertight by a watertight device 20 (described later) so that liquids such as water do not flow out through the gaps between them.

[0025] The winding shaft 15 is rotatably provided on both ends of the shutter case 11, and winds and unwinds the shutter curtain 12. A chain 16 connects a driving sprocket provided on the rotating shaft of the motor 17 to a driven sprocket provided on the rotating shaft of the winding shaft 15. Therefore, the rotational driving force of the motor 17 is transmitted to the winding shaft 15 side via the chain 16, and when the motor 17 rotates, the winding shaft 15 rotates via the chain 16, thereby controlling the opening and closing operation of the shutter curtain 12.

[0026] A brake (not shown) is attached to the motor 17, and in normal operation, this water stop opening / closing device 10 mechanically holds the open state in which the shutter curtain 12 is wound around the winding shaft 15 by the brake attached to the motor 17. When an emergency signal BS indicating a fire or the like is input from the outside to the interlocking repeater 19, the interlocking repeater 19 transmits a close command signal to the motor 17 and the shutter control panel 30, which releases the brake of the motor 17 in response to the close command signal, releasing the open state of the shutter curtain 12 caused by the brake of the motor 17. When the open state caused by the brake of the motor 17 is released, the shutter curtain 12 naturally descends under its own weight, automatically closing the opening of the structure such as a building.

[0027] The emergency signal BS is a 24V DC voltage signal supplied from an external control room in the event of an emergency such as a fire, and is input to an interlocking repeater 19 for preventing harm. The interlocking repeater 19 is supplied with, for example, 100V AC power from the AC power line of the commercial power source.

[0028] In addition to or instead of inputting the emergency signal BS from the outside, a temperature sensor or the like may be provided inside the shutter case 11 near the opening of the lintel, i.e., in the area where the shutter curtain 12 rises and falls. This temperature sensor may be configured to be a high-temperature bimetal thermostat with an automatic reset type B contact that is always on and opens and turns off when the contact reaches a specified temperature (any temperature in the range of 100 to 300 degrees Celsius), and when the contact opens, it may be configured to output a signal indicating the occurrence of a fire or the like as a signal equivalent to the emergency signal BS.

[0029] The motor 17 is provided with a limit switch (not shown) for detecting the rotational position of the motor 17 and preventing over-winding or over-rewinding of the shutter curtain 12. A detection signal of the limit switch is input to the shutter control panel 30.

[0030] The shutter control panel 30 is configured as a microcomputer, and is supplied with AC power, for example, of 200 V, from the AC power line of a commercial power source. An operation switch (not shown) is housed inside the shutter control panel 30. The operation switch has an up (open) button, a stop (stop) button, and a down (close) button as control switches corresponding to the opening and closing operations of the shutter curtain 12, and outputs a control signal according to the operating state of each of these operation buttons. The operation switch also has an operation button for operating the watertight device 20, which will be described later, and outputs a control signal according to the operation state of the operation button. The shutter control panel 30 controls the rotation of the motor 17 based on control signals corresponding to the operating states of each operating button on an operating switch housed within the shutter control panel 30, and detection signals from a limit switch provided on the motor 17, and releases the brake of the motor 17 based on an emergency signal BS. In addition, the shutter control panel 30 controls the operation of the watertight device 20 in response to a control signal corresponding to the operating state of an operating button for operating the watertight device 20, which is stored in the shutter control panel 30.

[0031] As described below, the IoT control panel 40 connects the shutter control panel 30 and the surveillance camera 50 to the Internet. The surveillance camera 50 captures images of the surroundings of the shutter curtain 12. The surveillance camera 50 is installed in a position that allows the bottom end of the shutter curtain 12 in the closed state and the surrounding conditions such as flooding to be viewed. The images captured by the surveillance camera 50 are input to the IoT control panel 40.

[0032] 2 is a diagram showing an example of an IoT control panel. The IoT control panel 40 includes a communication device 41, a transceiver 42, a terminal block 43, a circuit breaker 44, a switching hub 45, a monitor display 46, a recorder 47, and an emergency power supply 48. The communication device 41 communicates with an Internet router, and wirelessly transmits to the transceiver 42 operation signals of a remote control terminal (described later) received via the Internet. The transceiver 42 outputs an operation signal of the remote control terminal wirelessly received from the communication device 41 to the shutter control panel 30 .

[0033] The terminal block 43 is connected to wiring for a power source, an operation switch (not shown), and the like. The circuit breaker 44 cuts off overcurrent flowing within the IoT control panel 40. The switching hub 45 is a line concentrator, and is connected to a LAN cable, a communication device 41, a recorder 47, a surveillance camera 50, and the like.

[0034] The monitor display 46 displays images captured by the surveillance camera 50. The images on the monitor display 46 are used, for example, for confirmation when an operator adjusts the field of view, image quality, etc. of the surveillance camera 50. The recorder 47 records the images of the surroundings of the shutter curtain 12 captured by the surveillance camera 50.

[0035] The emergency power supply 48 supplies power of the same voltage as the commercial power supply to the surveillance camera 50 and the shutter control panel 30 when commercial power supply is unavailable due to a power outage caused by a disaster such as flood. The surveillance camera 50 captures images of the surroundings of the shutter curtain 12 using power supplied from a commercial power source or an emergency power source 48 . In addition, the shutter control panel 30 controls the motor 17 and the watertight device 20 using power supplied from a commercial power source or an emergency power source 48. Even if the power supply from the commercial power source is cut off due to a power outage caused by a disaster such as a flood, power supplied from the emergency power source 48 is used to monitor the area around the shutter curtain 12, open and close the shutter curtain 12, and operate the watertight device 20. When power is supplied from the emergency power supply 48, the power supply to the recorder 47 is cut off, thereby reducing power consumption.

[0036] Below, an example will be described in which a smartphone is used as the remote control terminal. The remote control terminal is not limited to a smartphone, but may be any device that can connect to the Internet, such as a computer or tablet terminal. Application software for controlling the watertight opening / closing device 10 is installed in these remote control terminals.

[0037] 3 is a diagram showing an example of the configuration of a control system for a watertight opening / closing device. The control system 100 for the watertight opening / closing device 10 according to this embodiment includes a shutter control panel 30, an IoT control panel 40, a surveillance camera 50, a smartphone 60 as a remote control terminal, and an Internet cloud server 70 and a router 80.

[0038] The IoT control panel 40 transmits images of the surroundings of the shutter curtain 12 captured by the surveillance camera 50 connected to the switching hub 45 to an Internet router 80. The images of the surroundings of the shutter curtain 12 transmitted from the IoT control panel 40 are received by the smartphone 60 via the router 80 and the cloud server 70. The smartphone 60 displays the received images of the surroundings of the shutter curtain 12 on its own screen.

[0039] An operation signal related to the operation of the shutter curtain 12 and an operation signal related to the operation of the watertight device 20, which are generated by operating an operation button displayed on the screen of the smartphone 60 and described later, are transmitted from the smartphone 60 via the cloud server 70 and the router 80, and are received by the communicator 41 of the IoT control panel 40. Then, the operation signal received by the communicator 41 is wirelessly transmitted from the communicator 41 to the transceiver 42. The operation signal wirelessly received by the transceiver 42 is input from the transceiver 42 to the shutter control panel 30. The shutter control panel 30 controls the motor 17 in response to the input operation signal related to the operation of the shutter curtain 12 to open / close and stop the shutter curtain 12. Also, in response to the input operation signal related to the operation of the watertight device 20, the shutter control panel 30 controls the watertight device 20 to start a watertight state between the waterstop 12a and the guide rails 13, 14 and to release the watertight state.

[0040] On the other hand, an operating signal indicating that the shutter curtain 12 is in operation, a water stop ON signal or water stop OFF signal indicating the start or release of the watertight state by the watertight device 20, a detection signal from a limit switch (not shown), an obstacle detection signal from an obstacle detection device (not shown), etc. are input from the shutter control panel 30 to the transceiver 42 and wirelessly transmitted from the transceiver 42 to the communication device 41. The communication device 41 transmits these signals and a communication confirmation signal for confirming the connection state to the Internet to the router 80, and these transmitted signals are received by the smartphone 60 via the router 80 and the cloud server 70.

[0041] Using the IoT control panel 40, the surveillance camera 50 and the shutter control panel 30 are connected to the Internet, images from the surveillance camera 50 are displayed on the smartphone 60 via the Internet, and the shutter control panel 30 is remotely controlled by the smartphone 60 via the Internet, so that the operation of the shutter curtain 12 can be safely and reliably controlled from a remote location while checking the flooding state and the presence or absence of obstacles.

[0042] 4A and 4B are diagrams for explaining the operation of the watertight device, and show a cross-sectional view of the waterstop 12a and the guide rails 13 and 14 taken along the line AA in FIG. The waterstop 12a has a hollow structure with a cavity therein in order to reduce its weight. The watertight device 20 includes an electric actuator 21 and a pressing mechanism 22. The pressing mechanism 22 moves in the vertical direction in Figures 4(a) and (b) by the operation of the electric actuator 21. FIG. 4(a) shows a state in which the watertight state between the waterstop plate 12a and the guide rails 13, 14 is released, and FIG. 4(b) shows a watertight state.

[0043] In Figures 4(a) and (b), a strip-shaped water stop rubber 12b is attached to both ends of the surface of the water stop plate 12a facing the inner wall of the guide rails 13 and 14 at the lower side of the drawing, spanning the height of the water stop plate 12a in the forward and backward directions of the drawing. In addition, a pressing mechanism 22 is attached to the guide rails 13 and 14, facing the surface of the waterstop plate 12a opposite to the surface to which the waterstop rubber 12b is attached, across approximately the height of the waterstop plate 12a, as shown by the dashed line in Figure 1. Incidentally, instead of being provided over substantially the entire height of the waterstop 12a, the pressing mechanisms 22 may be provided at least at the four corners of the waterstop 12a.

[0044] When starting a watertight state between the waterstop plate 12a and the guide rails 13, 14, the operator of the smartphone 60 operates a waterstop start (waterstop ON) button described later to instruct the start of waterstop. Also, when releasing the watertight state between the waterstop plate 12a and the guide rails 13, 14, the operator of the smartphone 60 operates a waterstop release (waterstop OFF) button described later to instruct the release of waterstop.

[0045] When the water stop release (water stop OFF) button is operated, the electric actuator 21 moves the pressing mechanism 22 to the position shown in Fig. 4(a). As a result, a gap is created between the water stop rubber 12b attached to the water stop plate 12a and the inner walls of the guide rails 13 and 14, and the watertight state between the water stop plate 12a and the guide rails 13 and 14 is released.

[0046] When the water stop start (water stop ON) button is operated, the electric actuator 21 moves the pressing mechanism 22 to the position shown in Fig. 4(b). The pressing mechanism 22 comes into contact with the water stop plate 12a and moves the water stop plate 12a toward the inner wall of the guide rails 13, 14 on the lower side of the drawing as indicated by the arrow, and presses the water stop rubber 12b attached to the water stop plate 12a against the inner wall of the guide rails 13, 14 in close contact therewith. This brings the water stop plate 12a and the guide rails 13, 14 into a watertight state.

[0047] In addition, on the inside of the shutter curtain 12, on the floor surface with which the lower end of the waterstop 12a contacts, a water pressure resistant receiver (not shown) is provided which is in close contact with the lower end of the waterstop 12a and receives the water pressure applied to the waterstop 12a.As a watertight device, this water pressure resistant receiver makes the waterstop 12a and the floor surface with which the lower end of the waterstop 12a contacts watertight.

[0048] In addition, when the watertight opening / closing body device is a panel shutter device which opens and closes a panel-shaped opening / closing body up and down, a strip-shaped watertight rubber is attached to the bottom surface of the panel-shaped opening / closing body across the width of the panel-shaped opening / closing body, and the watertight device includes a pressing mechanism which presses the panel-shaped opening / closing body against the floor surface and an electric actuator which moves the pressing mechanism, and these functions make the panel-shaped opening / closing body and the floor surface watertight.

[0049] Below, an example of the operation switches that are displayed on the screen of the smartphone 60 when application software for controlling the water shut-off opening / closing device 10 is started will be described. FIG. 5 is a diagram showing an example of a method for restricting the water stop release operation using an operation button. 5(a) is an example in which the layout of each operation button of the operation switch displayed on the smartphone 60 is the same as the layout of each operation button of the operation switch provided in the shutter control panel 30. In this example, an up (open) button 61, a stop (stop) button 62, and a down (close) button 63 are arranged in a vertical line. To the right of these, a water stop start (water stop ON) button 64 for instructing the start of a watertight state by the watertight device 20, and a water stop release (water stop OFF) button 65 for instructing the release of the watertight state by the watertight device 20 are arranged in a vertical line.

[0050] 5(b) is an example in which the water stop release (water stop OFF) button is not displayed on the screen of the smartphone 60. In this example, since the water stop release (water stop OFF) button is not displayed, the operator of the smartphone 60 cannot perform the water stop release operation.

[0051] FIG. 5(c) is an example in which a surveillance camera image 66 of the surroundings of the shutter curtain 12 captured by the surveillance camera 50 is displayed together with operation buttons. In this example, operation of the water stop release (water stop OFF) button 65 is restricted and operation of the water stop release (water stop OFF) button 65 is disabled until the surveillance camera image 66 is displayed for a predetermined period of time (e.g., a few seconds). Then, after the surveillance camera image 66 is displayed for a predetermined period of time, the restriction on the operation of the water stop release (water stop OFF) button 65 is lifted, and the operation of the water stop release (water stop OFF) button 65 becomes valid. Therefore, the operator is given an opportunity to check the environment around the shutter curtain 12.

[0052] FIG. 5(d) shows an example in which, when the water stop release (water stop OFF) button 65 is operated, a dialogue box 67 is displayed on the screen of the smartphone 60 to inquire as to whether or not the image around the shutter curtain 12 has been confirmed. Until a confirmation input (YES) is made, any operation of the water stop release (water stop OFF) button 65 that has already been performed is put on hold. Then, after the confirmation input (YES) is made, the hold on the operation of the water stop release (water stop OFF) button 65 is released, and water stop release is started. Therefore, it is prevented that the water stop state is released without checking the image around the shutter curtain 12.

[0053] According to the example shown in FIG. 5(b), FIG. 5(c) or FIG. 5(d), there is no risk of the water stop release (water stop OFF) button 65 being operated accidentally, releasing the water stop state of the shutter curtain 12 and causing water intrusion.

[0054] FIG. 6 is a diagram showing an example of the arrangement of a stop (stop) button, a water stop start (water stop ON) button, and a water stop release (water stop OFF) button. FIG. 6(a) is an example in which the arrangement of each operation button of the operation switch displayed on the smartphone 60 is the same as the arrangement of each operation button of the operation switch provided in the shutter control panel 30, similar to FIG. 5(a).

[0055] 6(a), the stop (pause) button 62 is disposed on the left side in the short side direction of the substantially rectangular smartphone 60. Therefore, the operability of the stop (pause) button 62 changes depending on whether the substantially rectangular smartphone 60 is held in the left hand in the short side direction and the stop (pause) button 62 is operated with the left thumb or whether the substantially rectangular smartphone 60 is held in the right hand in the short side direction and the stop (pause) button 62 is operated with the right thumb.

[0056] Figure 6 (b) is an example in which the stop (stop) button 62 is placed in the center of the short side of the approximately rectangular smartphone 60, and the water stop start (water stop ON) button 64 and the water stop release (water stop OFF) button 65 are placed to the left and right of the stop (stop) button 62. According to the example of FIG. 6(b), the operability of the stop (pause) button 62 remains the same regardless of whether the approximately rectangular smartphone 60 is held in the short side direction with the left or right hand, and the stop (pause) button 62, which may require urgent operation, can be operated smoothly.

[0057] In the example of Figure 6 (b), the stop (stop) button 62, water stop start (water stop ON) button 64, and water stop release (water stop OFF) button 65 are arranged at close intervals along the short side of the approximately rectangular smartphone 60, so there is a risk of erroneous operation in which the water stop start (water stop ON) button 64 or the water stop release (water stop OFF) button 65 is mistakenly operated when intending to operate the stop (stop) button 62. Therefore, if the shutter control panel 30 is configured to stop the raising or lowering of the shutter curtain 12 when the water stop start (water stop ON) button 64 or the water stop release (water stop OFF) button 65 is operated while the shutter curtain 12 is raising or lowering, the shutter curtain 12 can be stopped even if there is an erroneous operation of the water stop start (water stop ON) button 64 or the water stop release (water stop OFF) button 65 instead of the stop (stop) button 62.

[0058] In the above-described embodiment, a water stop shutter device that is deployed in a vertical lifting manner has been described as an example, but the present invention can be applied to an opening / closing body device in which a water stop opening / closing body such as a shutter, sheet, or panel is deployed in a lateral pulling manner or a horizontal pulling manner. Examples of the opening / closing body device include a shutter device, a window shutter device, a blind device, a roller screen device, a drapery device, a movable partition device, a sliding door device, a swing door device, a folding door device, a gate device, an awning device, and a waterproof board device.
