Description

[Technical field]

[0001] The present invention relates to a network camera system capable of remotely monitoring the inside and outside of an opening / closing device installed in an opening such as a window or an entrance / exit of a structural body including a building such as a house, a building, a factory, a warehouse, etc., an opening / closing device equipped with a network camera system, and an opening / closing control method, and in particular to a network camera system capable of photographing the indoor side of an opening / closing device, an opening / closing control system, and an opening / closing control method. [Background technology]

[0002] For opening and closing devices such as shutters and doors installed in the openings of structures including houses, buildings, factories, warehouses, etc., electric shutters and electric doors that perform the opening and closing operation electrically are often used. Such devices that perform the opening and closing operation electrically include wired dedicated switches with three types of switches for opening and closing, or wireless dedicated switches for remote control. In response to the operation of each of these switches, the opening and closing device controls the opening and closing operation of the shutters and doors.

[0003] Recently, on the other hand, by installing a dedicated remote control application on a mobile communication terminal such as a smartphone, the mobile communication terminal can have the same functions as a dedicated wireless switch. Also, by installing the remote control application on multiple such mobile communication terminals, multiple people can each individually control the opening and closing device.

[0004] Patent document 1 describes an opening and closing control system that is configured to control multiple opening and closing devices within a building by installing a dedicated remote control application on a mobile communication terminal such as a smartphone and connecting it to a wireless communication device (transmitter / receiver base station). [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Patent Publication No. 2021-10087 DISCLOSURE OF THEINVENTION [Problem to be solved by the invention]

[0006] As described in Patent Document 1, when a wireless communication device (transmitter / receiver parent unit) that can configure a remote control device for an opening / closing device such as a shutter device using a mobile communication terminal such as a smartphone is used, the user does not need to purchase multiple dedicated remote control devices for multiple opening / closing devices, which reduces the economic burden on the user and is therefore preferable to the user.

[0007] The opening / closing control system described in Patent Document 1 is configured so that opening / closing devices such as a garage shutter device and a window shutter device can be controlled remotely by connecting a mobile communication terminal to an access point in the house via the Internet and accessing a wireless communication device (transmitter / receiver master device) from outside using the mobile communication terminal. Also, the opening / closing control system described in Patent Document 1 is configured so that it can be remotely controlled from outside via the Internet using the mobile communication terminal.

[0008] In the opening and closing control system described in Patent Document 1, a human sensor is provided in the garage to detect whether or not a person is present, and to prevent the person from being locked in the garage. Also, if there is a person on the balcony and the window shutter device automatically closes, there is a possibility that the person will be pushed out onto the balcony, so to prevent this, a human sensor is provided in the window shutter device. It is also described that a surveillance camera or the like may be used instead of the human sensor.

[0009] When a surveillance camera is installed to remotely monitor the inside of a garage, it functions as a network camera whose main purpose is to check the safety when the shutter is closed. Although a network camera is installed to remotely monitor the inside and outside of the garage when the shutter is closed, there is a demand not to capture the inside of the garage when the shutter is closed from the viewpoint of privacy protection, in case the network camera is hacked. Since there is a demand to capture the outside of the garage even when the shutter is closed, it is conceivable to install a network camera only on the outside of the garage. However, if the camera is installed only on the outside of the garage, there is an inconvenience in that it is not possible to check from the network camera whether someone is trapped inside the garage when the shutter is closed, unless the network camera image is monitored in real time.

[0010] The present invention has been made in consideration of the above-mentioned points, and aims to provide a network camera system, an opening / closing control system, and an opening / closing control method that make it possible to visually confirm the trapped state when and during the closing operation of an opening / closing member, even if the camera is set so that it cannot capture the inside of the room when the opening / closing member is closed. [Means for solving the problem]

[0011] A feature of the network camera system of the present invention is that the network camera system comprises a camera means for photographing the inside and outside of a structure structure room, the camera means being provided near the opening of an opening / closing device that separates the inside and outside of the structure structure room by moving an opening / closing member from the periphery of the opening in response to a control signal, and a mobile communication terminal means for receiving and displaying the images photographed by the camera means via the Internet, the camera means being provided outside the structure structure room so that the photographing angle of view of the camera means is directed from the outside to the inside of the room and so that when the opening / closing member is closed, the closed opening / closing member makes the inside of the structure structure room a blind spot for the camera means, the camera means records images photographed when the opening / closing member starts to close and during the closing operation, and the recorded images are displayed on the mobile communication terminal means.

[0012] The opening and closing devices include window shutter devices, garage shutter devices, other shutter devices, blind devices, roller screen devices, drapery devices, sliding door devices, swing door devices, movable partition devices, awning devices, waterproof board devices, gate devices, etc., and these opening and closing devices are provided at multiple locations inside and outside the structural body room of the structure. The opening and closing devices use a mobile communication terminal means as an operator for instructing each operation such as opening / closing / stopping, stopping midway, or adjusting the ventilation volume or the amount of light (each of these operations is simply called opening and closing operation). The mobile communication terminal means is configured to cause the control means to execute opening and closing operations such as opening / closing / stopping, stopping midway, or adjusting the ventilation volume or the amount of light by operating an operation button displayed on the display screen.

[0013] The network camera system is configured such that video captured by the camera means can be received and played back by other devices (mobile communication terminal means) via the Internet. The camera means is provided near the opening of an opening / closing device that separates the inside and outside of the structure structural body room by moving an opening / closing member from the periphery of the opening of the structure structural body room in response to a control signal. The camera means captures images of the inside and outside of the structure structural body room. The video captured by the camera means is received by the mobile communication terminal means via the Internet and displayed on its screen. The camera means has a shooting angle of approximately 90 degrees, so it is installed on the outside of the structural body room and positioned so that it can shoot the entire outside and inside of the room. When the opening and closing member of the opening and closing device is closed, the closed opening and closing member blocks shooting of the inside of the room, making the inside of the room a blind spot from the camera means and an area that cannot be shot.

[0014] In this invention, the camera means records the video taken by the opening / closing device from when the opening / closing member starts to close until the closing operation is completed, that is, when the closing operation starts and during the closing operation. The recorded video is transmitted to the portable communication terminal means after the closing operation is completed and displayed on the portable communication terminal means. By visually checking the video displayed on the display screen, the user can recognize the state of the room during the closing operation and visually check the trapped state during the closing operation of the opening / closing member. The recorded video is transmitted to the portable communication terminal means via the Internet, but if the portable communication terminal means is connected to the opening / closing device via a wireless communication method, the video may be transmitted to the portable communication terminal means via that wireless communication method without passing through the Internet. The video taken by the camera means may be recorded in a memory built into the camera means and transmitted to the portable communication terminal means, etc. In addition, if the camera means is a type that constantly records video like a surveillance camera, timing information of each operation at the start of the closing operation and during the closing operation may be recorded, and the video information may be transmitted based on the timing information during playback.

[0015] The opening and closing control system of the present invention is characterized in that it comprises an opening and closing body means that is provided at an opening of a structure structural room and performs opening and closing operations, a control means that controls the operation of the opening and closing body means, a portable communication terminal means that is connected to the control means via a communication line and that displays an operator screen equivalent to the operator of the operator means by starting an application and transmits the control signal to the control means in response to the operation of the operator screen, and a camera means that is provided near the opening and photographs the inside and outside of the structure structural room and transmits the photographed images to the portable communication terminal means via the Internet, in which the opening and closing control system is provided with a camera means that photographs the inside and outside of the structure structural room and transmits the photographed images to the portable communication terminal means via the Internet, the camera means is provided outside the structure structural room so that the photographing angle of the camera means is from the outside to the inside of the room and when the opening and closing member is closed, the closed opening and closing member makes the inside of the structure structural room a blind spot for the camera means, and the image photographed at the start of the closing operation of the opening and closing member and during the closing operation is recorded, and the recorded image is displayed on the portable communication terminal means. This is an invention of an opening and closing control system having the features of the network camera system.

[0016] The opening and closing control method of the present invention is characterized in that it uses a control means to control the operation of an opening and closing member installed in an opening of a structure's structural body room, connects a mobile communication terminal means to the control means via a wireless communication method to control the operation of the opening and closing member on the mobile communication terminal side, photographs the inside and outside of the structure's structural body room with a camera means installed near the opening, and transmits the photographed images to the mobile communication terminal means via the Internet, and the camera means is installed outside the structure's structural body room so that the photographing angle of the camera means is from the outside to the inside of the room and when the opening and closing member is closed, the closed opening and closing member makes the inside of the structure's structural body room a blind spot for the camera means, records images photographed at the start of and during the closing operation of the opening and closing member, and displays the recorded images on the mobile communication terminal means. This is an invention of an opening and closing control method having the features of the network camera system. Effect of the Invention

[0017] The network camera system, opening / closing control system, and opening / closing control method of the present invention have the advantage that even if the camera is set so that it cannot capture the inside of the room when the opening / closing member is closed, it is possible to visually confirm the trapped state when and during the closing operation of the opening / closing member.

[0019] A preferred embodiment of an opening and closing control system equipped with a network camera system according to the present invention will be described below with reference to the attached drawings. In this embodiment, an opening and closing control system that controls a group of shutter devices that are controlled to open and close vertically as multiple opening and closing devices will be described as an example. Figure 1 is a diagram showing the schematic configuration of a building in which an opening and closing control system equipped with a network camera system according to the present invention is installed.

[0020] The shutter device group consisting of the opening / closing control system in Fig. 1 is composed of a garage shutter device 1 installed in a garage such as a carport, and window shutter devices 2-4 installed in the windows that are the openings of each room of a structural body (building). The garage shutter device 1 and the window shutter devices 2-4 are basically composed of a shutter case, a shutter curtain, a guide rail, a motor, a shutter drive circuit, an opening / closing control circuit, a transmitter / receiver, a remote control switch, etc. Note that in Fig. 1, the motor, the shutter drive circuit, and other components such as a winding shaft and a chain are not shown.

[0021] The garage shutter device 1 is an opening / closing device for a vehicle, and the window shutter devices 2 to 4 are a plurality of opening / closing devices provided corresponding to a plurality of openings. In the opening / closing control system according to this embodiment, in addition to the structural body (building) on ​​which the shutter device group as shown in Fig. 1 is installed, a plurality of structural bodies (buildings) on which shutter device groups of a different aspect from that shown in Fig. 1 are installed are assumed to exist at separate locations. Fig. 1 shows one example of these buildings, and opening / closing devices other than those shown in Fig. 1 may be installed in the building.

[0022] The garage shutter device 1 and the window shutter device 3 are equipped with surveillance cameras 14, 34 that constitute a network camera system. The surveillance camera 14 of the garage shutter device 1 is installed outside the garage, in front of the garage opening, and monitors whether or not there are people near and inside the garage. If there is a person in the garage and the garage shutter device 1 is closed, there is a possibility that the person will be trapped inside the garage, so this is to prevent this. Along with the surveillance camera 14, a human presence sensor 19 is installed inside the garage, and the human presence sensor 19 detects the presence of a person when the garage shutter is closed.

[0023] The surveillance camera 34 of the window shutter device 3 is installed outside the building, behind the opening of the French window, to monitor whether or not there is anyone on the balcony 35. If there is someone on the balcony 35 and the window shutter device 3 closes, there is a possibility that the person will be pushed out onto the balcony, so this is to prevent this. A human presence sensor 39 is also installed in addition to the surveillance camera 34, and the human presence sensor 39 detects the presence of a person when the window shutter is closed. The surveillance camera 34 is installed so as to only film the outside of the building and not to film the inside of the room for privacy reasons.

[0024] Surveillance cameras and / or motion sensors may also be installed in other areas where a person may be trapped and / or chased away. Motion sensors detect the presence of people using infrared rays, ultrasonic waves, visible light, etc. Surveillance cameras 14, 34 may be composed of one or more cameras. Motion sensors 19, 39 may also be composed of one or more sensors. Note that motion sensors are different from obstacle sensors for preventing harm that are provided in the shutter device, and detect whether or not a person is present in a specified area at a certain distance from the opening / closing device.

[0025] The shutter cases are provided above each opening. The guide rails are provided on both ends of the garage openings and windows so as to contact both ends of the shutter curtain, and are made of metal members with guide grooves with a U-shaped cross section that span from the lintel to the floor and below the window frame. The shutter curtain rises and falls along the guide grooves of these guide rails, and opens and closes the openings and windows, stopping or stopping midway (half-open or half-closed). In this specification, half-open means a state stopped midway in an opening operation, and half-close means a state stopped midway in a closing operation.

[0026] The winding shaft (not shown) is rotatably provided on both ends of the shutter case, and winds and unwinds the shutter curtain. A chain (not shown) connects a driving sprocket provided on the rotating shaft of the motor with a driven sprocket provided on the rotating shaft of the winding shaft. Therefore, the rotational driving force of the motor is transmitted to the winding shaft side via the chain, and when the motor rotates, the winding shaft rotates via the chain, and the opening and closing operation of the shutter curtain is controlled to open, close, stop, or stop halfway.

[0027] Although not shown, the shutter drive circuit is provided in each shutter case. The shutter drive circuit is configured as a microcomputer, and is supplied with power from the outside via the power line. The shutter drive circuit controls the rotation of the motor based on a control signal from the opening / closing control circuit 11, 21, 31, 41 to control the opening / closing operation such as opening / closing, stopping, or stopping midway of the shutter curtain.

[0028] An encoder is coupled to the motor's rotating shaft, which detects the rotational position of the motor and outputs it to the shutter drive circuit. An HA signal (a signal indicating a closed or open state) is output based on the rotational position of the motor. In Fig. 1, the opening / closing control circuits 11, 21, 31, 41 each have a built-in antenna that receives control signals from the remote control switches 12, 22, 32, 42. The remote control switches 12, 22, 32, 42 are wireless control means dedicated to the shutter device and equipped with an open button, a stop button, and a close button.

[0029] The motor is provided with a current detector (current sensor) and a voltage detector (voltage sensor) that detect the drive current and drive voltage supplied to the motor from the shutter drive circuit, and the detected drive current and drive voltage values ​​are fed back to the shutter drive circuit. In addition, the motor is provided with a temperature detector (temperature sensor), and the detected temperature is also fed back to the shutter drive circuit. The shutter drive circuit controls the rotation speed of the motor based on a detection signal indicating the rotation position of the motor (shutter position) output from the encoder, and detection signals indicating the drive current, drive voltage, and temperature of the motor during operation output from the current detector, voltage detector, and temperature detector. When a drive current is detected by the current detector, the motor is in a driven state, and when the drive current is not detected (zero), the motor can be determined to be in a non-driven state.

[0030] In this embodiment, remote control switches 12, 22, 32, 42 and transmitter / receiver slaves 13, 23, 33, 43 are provided for the garage shutter device 1 and the window shutter devices 2 to 4, respectively, a transmitter / receiver master unit 50 and an access point (Wireless LAN access point) 60 are installed at predetermined locations within the building, and a user terminal such as a mobile communication terminal 70 and a cloud server described later are connected via a network to construct an opening / closing control system equipped with a network camera system that can be controlled from outside via the Internet. This transmitter / receiver master unit 50 is a wireless communication device.

[0031] 1, the transmitter-receiver slave units 13, 23, 33, 43 are shown with antennas connected to the remote control operation switches 12, 22, 32, 42 and the transmitter-receiver master unit 50. The remote control operation switches 12, 22, 32, 42 are wireless operation means dedicated to the shutter device, equipped with an open button, a stop button, and a close button. The transmitter-receiver slave unit 13 and the remote control operation switch 12 of the garage shutter device 1 are connected in a predetermined frequency band (for example, 426 [MHz]), and are each connected via a predetermined ID.

[0032] Similarly, the window shutter devices 2-4 are connected to the remote control switches 22, 32, 42 in a specific frequency band, and are connected one-to-one via predetermined IDs. In this embodiment, the remote control switch 12 is assigned an id12, the remote control switch 22 an id22, the remote control switch 32 an id32, and the remote control switch 42 an id42 as unique remote control IDs, and the transmitting / receiving slave units 13, 23, 33, 43 are controlled using these remote control IDs.

[0033] Although not shown, the garage shutter device 1 and the window shutter devices 2-4 may be provided with a wall switch, which is a wired operating means, near each opening in addition to the remote control switches 12, 22, 32, 42. The wall switch is a wired operating means (dedicated switch) dedicated to the shutter device, which has an open button, a stop button, and a close button, and is originally directly connected to the opening / closing control circuits 11, 21, 31, 41 of the garage shutter device 1 and the window shutter devices 2-4, and transmits a control signal corresponding to the operating state of each opening / closing operating button to the opening / closing control circuits 11, 21, 31, 41.

[0034] Each opening / closing control circuit 11, 21, 31, 41 controls the opening / closing operation of the shutter curtain in response to a control signal corresponding to the operation state of the remote control switch 12, 22, 32, 42 and the wall switch. The garage shutter device 1 and the window shutter devices 2-4 are designed to be able to directly control the opening / closing operation of the garage shutter device 1 and the window shutter devices 2-4 in response to the operation of the wall switch, independently of this opening / closing control system. Note that the wall switch may also be provided with a button for stopping midway.

[0035] The transmitter-receiver slaves 13, 23, 33, 43 are installed so as to be electrically connected to the respective opening / closing control circuits 11, 21, 31, 41 by wires. The transmitter-receiver slaves 13, 23, 33, 43 are wirelessly connected to the transmitter-receiver master unit 50 by a specific low-power radio (for example, a frequency of 429 [MHz]). The transmitter-receiver master unit 50 has a built-in antenna for receiving signals from the respective remote control operation switches 12, 22, 32, 42. The access point (wireless LAN access point) of the wireless router 60 is connected to the transmitter-receiver master unit 50 via WiFi. Furthermore, a user terminal such as a mobile communication terminal 70 can be connected to this wireless router 60 via WiFi. In addition to the mobile communication terminal 70, a user terminal such as a notebook computer or a desktop computer can be connected to this wireless router 60 via WiFi or various cables such as a LAN cable.

[0036] The specific frequency band connecting the transceiver slaves 13, 23, 33, 43 and the remote control switches 12, 22, 32, 42 may be the same as or different from the specific frequency band connecting the transceiver slaves 13, 23, 33, 43 and the transceiver master 50. When the specific frequency bands are different, the transceiver slaves 13, 23, 33, 43 receive the received signal by switching the frequency of the received signal by software.

[0037] In this embodiment, at least one of the transmitter-receiver master unit 50 and the wireless router (access point) 60 is not housed in any shutter case, and is installed outside the shutter case. Furthermore, when the transmitter-receiver master unit 50 and the wireless router (access point) 60 are installed near any shutter case (i.e., a shutter device equipped with this shutter case), and the height can be determined by visual inspection or other reasons, it is preferable to install them at a position below the shutter case, taking into account ease of installation and maintenance. Of course, even if the transmitter-receiver master unit 50 and the wireless router (access point) 60 are installed inside the shutter case, the installation position is arbitrary as long as the communication is possible and the position does not interfere with the movement of the shutter curtain, such as opening / closing and rolling up.

[0038] The mobile communication terminal 70 is, for example, a mobile communication terminal such as a mobile phone, a PHS, a smartphone (multifunctional mobile phone), a PDA, etc. In this embodiment, the mobile communication terminal 70 is configured as a smartphone, and has not only a normal calling function but also a touch panel display screen, and in response to the activation of various applications, remote control operation switches having the same functions as the buttons of the remote control operation switches 12, 22, 32, and 42 are displayed on the display screen, and by operating each of these buttons, the terminal functions as a remote control operation switch.

[0039] Various icons for starting a plurality of applications including a telephone call are displayed on the touch panel display screen of the mobile communication terminal 70, and the desired application can be started by touching the desired icon. FIG. 1 shows a state in which an application for an opening / closing control system is started and the operation buttons of an open button, a stop button, and a close button are displayed. The mobile communication terminal 70 has a short-range wireless communication function such as WiFi, infrared communication, and Bluetooth (registered trademark), and in this embodiment, it is connected to a wireless router (access point) 60 by WiFi, and is further connected to a transmission / reception master unit 50 and an external Internet via the wireless router (access point) 60. Note that, although one mobile communication terminal 70 is shown in the figure, a plurality of mobile communication terminals may be present.

[0040] Fig. 2 is an external view showing a schematic configuration of the transceiver unit in Fig. 1. The transceiver units 13, 23, 33, and 43 are equipped with a power line, a signal line, and a built-in antenna. In some cases, an external antenna connection line is also provided. In this embodiment, the transceiver units 13, 23, 33, and 43 are equipped with a dip switch setting unit 81 that indicates the type of shutter in addition to these normal wireless components.

[0041] In the figure, the dip switch setting section 81 is shown in an enlarged manner. As shown in the figure, this dip switch setting section 81 is composed of three dip switches SW1 to SW3. The setting states of these dip switches SW1 to SW3 are as shown in Table 82. That is, in the figure, when the dip switches SW1 to SW3 are "000", they indicate a standard type of sweeping window shutter device, when they are "001", they indicate a standard type of waist-high window shutter device, when they are "010", they indicate a slit type of sweeping window shutter device, when they are "011", they indicate a slit type of waist-high window shutter device, when they are "100", they indicate a blind type of sweeping window shutter device, when they are "101", they indicate a blind type of waist-high window shutter device, and when they are "110", they indicate a garage shutter.

[0042] By assigning dip switches SW1 to SW3 to other shutter types, eight types of shutters can be assigned. To assign more types, four or more dip switches should be provided. Note that the window shutter device 2 in Fig. 1 is set to the standard type waist-high window shutter device "001", the window shutter device 3 is set to the standard type sweep window shutter device "000", the window shutter device 4 is set to the slit type waist-high window shutter device "011", and the garage shutter device 1 is set to the garage shutter "110".

[0043] In the opening / closing control system of Fig. 1, remote control IDs (id12, id22, id32, id42) are set for the remote control operation switches 12, 22, 32, 42, the transceiver slave units 13, 23, 33, 43, and the transceiver master unit 50. Details of the setting process of these remote control IDs are described in the previously filed Patent Applications No. 2015-208071 and No. 2015-208072, and therefore will not be described here.

[0044] 3 is a diagram showing a state in which remote control IDs are set in the remote control operation switch, the transmitting / receiving slave unit, and the transmitting / receiving master unit. In each transmitting / receiving slave unit 13, 23, 33, 43, the corresponding remote control ID (id12, id22, id32, id42) is registered in association with the ID (id13, id23, id33, id43) of the transmitting / receiving slave unit 13, 23, 33, 43. The IDs and the DIP switch state signals are stored in association with each other, such as id12⇔id13, id12⇔110 in the remote control operation switch 12, id22⇔id23, id22⇔001 in the remote control operation switch 22, id32⇔id33, id32⇔000 in the remote control operation switch 32, and id42⇔id43, id42⇔011 in the remote control operation switch 42.

[0045] The same ID group and DIP switch status signal as those registered in each remote control operation switch 12, 22, 32, 42 are registered in the transmitting / receiving master unit 50. As a result, a bidirectional communication state is established between the transmitting / receiving slave units 13, 23, 33, 43 and the transmitting / receiving master unit 50 via one of the communication lines 13b, 23b, 33b, 43b based on the receiving ID and transmitting ID in the transmitting / receiving slave units 13, 23, 33, 43. When a bidirectional communication state is established between the transmitting / receiving slave units 13, 33 and the transmitting / receiving master unit 50, video information from the monitoring cameras 14, 34, detection information from the human sensors 19, 39, and detection signals from the current detector, voltage detector, temperature detector, etc. are transmitted to the transmitting / receiving master unit 50 in real time as status signals.

[0046] This enables the master transmitter / receiver 50 to recognize the presence of people in the garage and on the balcony 35 based on the detection information from the human presence sensors 19, 39. When the presence of a person is recognized by the human presence sensors 19, 39, the video information from the surveillance cameras 14, 34 is displayed on a user terminal such as a mobile communication terminal 70 or a notebook or desktop computer, making it possible to view the video information remotely. In addition, the master transmitter / receiver 50 transmits detection signals from a current detector, a voltage detector, a temperature detector, etc., to a cloud server (described later) at a predetermined timing.

[0047] Fig. 4 is a diagram showing an example of a display screen of a mobile communication terminal. In Fig. 4, mobile communication terminal 701 shows an example of a screen showing an initial state in which an application for an opening / closing control system is started. Selection buttons such as "individual shutter", "all shutters in building", "inside building shutter", and "garage shutter" are displayed on the initial state screen of mobile communication terminal 701.

[0048] The "individual shutter" selection button is selected when individually controlling a selection from the garage shutter device 1 and window shutter devices 2-4 shown in Fig. 1. The "all shutters in building" selection button is selected when simultaneously controlling the garage shutter device 1 and window shutter devices 2-4 shown in Fig. 1. The "inside building shutters" selection button is selected when simultaneously controlling the window shutter devices 2-4 installed in the building among those shown in Fig. 1.

[0049] The "Garage shutter" selection button is selected when controlling only the garage shutter device 1 shown in FIG. 1. When the human sensor 19 detects the presence of a person in the garage, a human mark indicating the presence of a person is displayed on the "Garage shutter" selection button. By visually recognizing this human mark, the user can recognize that a person is present in the garage. The selection button on which the human mark is displayed may be shaded or the like to indicate that it cannot be operated, so that it can be distinguished from other operable buttons. Furthermore, by tapping this human mark, video information from the surveillance camera 14 is displayed on the screen of the mobile communication terminal 70. The method of displaying the video information will be described later.

[0050] 4, mobile communication terminal 702 shows an example of a screen displayed when the selection button for "individual shutter" is operated on mobile communication terminal 701, which displays the initial state screen. Selection buttons such as "garage shutter," "1st floor waist-high window shutter ST," "2nd floor bay window shutter ST," and "2nd floor waist-high window shutter SL" are displayed on mobile communication terminal 702 as the names of devices that can be controlled to open and close, as shown in FIG.

[0051] The "Garage shutter" selection button corresponds to the garage shutter device 1 shown in Fig. 1. The "1st floor waist-high window shutter ST" selection button corresponds to the standard type waist-high window shutter device shown in Fig. 1. The "2nd floor bay window shutter ST" selection button corresponds to the standard type bay window shutter device 3 shown in Fig. 1. The "2nd floor waist-high window shutter SL" selection button corresponds to the slit type waist-high window shutter device shown in Fig. 1.

[0052] The selection button for "Garage shutter" on the screen of the mobile communication terminal 702 displays a person mark indicating that someone is in the garage, similar to the screen of the mobile communication terminal 701, and is shaded to indicate that the button cannot be operated. On the other hand, the selection button for "2nd floor bay window shutter ST" on the screen of the mobile communication terminal 702 does not display a person mark. This means that there is someone in the garage, but no one on the veranda 35. Note that the half-close operation may be operable even if the presence of a person is confirmed. This is because the half-closed state does not correspond to a locking or kicking out.

[0053] These correspondences can be set in the base unit 50 when two-way communication between the base unit 50 and the transmitter-receiver handsets 13, 23, 33, 43 is established, as shown in Fig. 3, and the system is configured so that the set contents are displayed on a user terminal such as the mobile communication terminal 70. Therefore, instead of "2nd floor bay window shutter ST" and "2nd floor waist-high window shutter SL", names such as "2nd floor XX room window shutter" and "2nd floor △△ room window shutter" may be assigned to make them easier to understand.

[0054] In this way, the name assigned to the transmitting / receiving base unit 50 is transmitted to a user terminal such as a mobile communication terminal 70 via the wireless router (access point) 60, so there is no need to separately register a user terminal such as the mobile communication terminal 70 in the transmitting / receiving base unit 50. By simply connecting a user terminal such as the mobile communication terminal 70 to the wireless router (access point) 60, the opening and closing operations of the garage shutter device 1 and the window shutter devices 2 to 4 can be appropriately controlled, such as opening and closing, stopping, or stopping midway, using a user terminal such as the mobile communication terminal 70.

[0055] In FIG. 4, the mobile communication terminal 703 shows an example of a screen when the selection button of the device name "garage shutter" that can be controlled to open and close, displayed on the mobile communication terminal 702, is operated. The device name "garage shutter" that is currently the control target is displayed at the top of the display screen of the mobile communication terminal 703, and each operation button for opening and closing is displayed below it. In the lower right part of the display screen of the mobile communication terminal 703, an icon of the device name "camera" is displayed when a visible surveillance camera exists. Note that, if there is a person in the garage, the above-mentioned person mark is displayed. By tapping this "camera" icon or person mark, the image of the surveillance camera 14 is displayed on the display screen of the mobile communication terminal 703. Also, if the image captured by the surveillance camera 14 during the closing operation of the garage shutter device 1 has been recorded, a mark indicating the presence of a recorded image is displayed on the "camera" icon, and the recorded image can be displayed on the mobile communication terminal 70 by tapping it.

[0056] 4, the mobile communication terminal 704 shows an example of a screen displayed when a selection button for the name of a device that can be opened and closed, "second floor waist-high window shutter SL," displayed on the mobile communication terminal 702, is operated. The name of the device currently to be controlled, "second floor waist-high window shutter SL," is displayed at the top of the display screen of the mobile communication terminal 704, and below that are displayed operation buttons for opening and closing, a mid-way stop button for half-opening or half-closing, and an operation button for ventilation and lighting to adjust the amount of ventilation or lighting.

[0057] As described above, the ventilation lighting operation button of the mobile communication terminal 704 is a slit type operation button displayed to adjust the amount of lighting, since the dip switch status signal indicating the type of shutter of the waist-high window shutter device is "011", which is a slit type. Similarly, when the dip switch status signal indicating the type of shutter is "101", which is a blind type, the "ventilation lighting" operation button for adjusting the amount of ventilation is displayed as in the mobile communication terminal 704. Therefore, when the dip switch status signal indicating the type of shutter is "000" or "001", which is a standard type, the "ventilation lighting" operation button is not displayed, and only the operation buttons for opening, closing, stopping, and stopping midway are displayed as in the mobile communication terminal 703. Note that the "ventilation lighting" operation button may be displayed in the same manner in the case of the standard type as well.

[0058] As described above, when the selection button of the open / close controllable device name "garage shutter", "1st floor waist-high window shutter ST", "2nd floor bay window shutter ST" or "2nd floor waist-high window shutter SL" displayed on the mobile communication terminal 702 is operated, the respective device names are displayed at the top of the display screen as shown in the mobile communication terminals 703 and 704, and it becomes possible to control the opening / closing stop, midway stop, or opening / closing operation of the ventilation amount or daylighting amount of any of the garage shutter device 1 and the window shutter devices 2 to 4 using the display screen of the mobile communication terminals 703 and 704. Note that in Fig. 4, the midway stop operation button and ventilation daylighting operation button are not displayed for the garage shutter device 1, but they may be displayed.

[0059] When the selection button for "all shutters in the building" is operated on the display screen of the mobile communication terminal 701, the words "all shutters in the building" are displayed on the upper part of the display screen of the mobile communication terminal 703, and the mobile communication terminal 703 can be used to control the opening and closing of all shutters at the same time. In the case of all shutters in the building, only the opening and closing operations are allowed, and the button for the stopping operation cannot be operated. This is because the time required for the opening and closing operation of the opening and closing device is different between the waist-high window shutters and the bay window shutters, and it is difficult for the operator to determine at what stage the stopping operation will occur when the shutters are stopped. Therefore, in this embodiment, the operation for stopping the shutters in the building is not allowed. Of course, it goes without saying that the shutters in the building may be configured to be able to be stopped for all shutters or some of them. In addition, it may be possible to set the shutters to be opened or closed only half or about one-third of the full open or closed state.

[0060] When the selection button for "inside building shutters" is operated on the display screen of mobile communication terminal 701, the display screen of mobile communication terminal 703 or 704 capable of operating "1st floor waist-high window shutter ST," "2nd floor bay window shutter ST," and "2nd floor waist-high window shutter SL" within the building as the names of devices that can be opened and closed as shown in Fig. 1 is displayed, and it becomes possible to control the opening / closing, stopping, or midway stopping of each window shutter, or the opening / closing operation of the ventilation volume or the lighting volume. Note that, in Fig. 1, remote control operation switches 32 and 42 show wireless operation devices dedicated to shutter devices equipped only with an opening / closing and stopping button, but they may be equipped with an operation button that can control the midway stopping and / or the opening / closing operation of the ventilation volume or the lighting volume in addition to the opening / closing and stopping operation button like mobile communication terminal 704 in Fig. 4.

[0061] When the selection button for the garage shutter is operated on the display screen of the mobile communication terminal 701, the display screen of the mobile communication terminal 703 is displayed, so that the opening and closing operation of the garage shutter device 1 can be controlled directly using the mobile communication terminal 703. That is, in the opening and closing control system shown in FIG. 1, the opening and closing operation of the garage shutter device 1 and the window shutter devices 2 to 4 can be appropriately controlled using a user terminal such as the mobile communication terminal 70 other than the remote control operation switches 12, 22, 32, and 42 dedicated to the opening and closing devices. The user terminal such as the mobile communication terminal 70 functions as a wireless operation device means shared by the garage shutter device 1 and the window shutter devices 2 to 4. In addition, since the transmission / reception master device 50 and the user terminal such as the mobile communication terminal 70 are connected via a wireless router (access point) 60, only user terminals such as the mobile communication terminal 70 authenticated by WEP (may be WPA, WPA2) are connected to the transmission / reception master device 50, so that high security can be established.

[0062] FIG. 5 is a diagram showing the connection relationship between the wireless router (access point) of the opening / closing control system of FIG. 1 and each device connected via the Internet. In FIG. 5, the same components as those in FIG. 1 are given the same reference numerals, and therefore the description thereof will be omitted. In FIG. 5, only the garage shutter device 1 and the window shutter devices 2-4 shown in FIG. 1 are shown for convenience, but in reality, there are a plurality of structural bodies (buildings) in which the opening / closing control system consisting of such opening / closing devices is installed, each at a separate location. The opening / closing control system shown in FIG. 5 is composed of the garage shutter device 1 and the window shutter devices 2-4, a transmitting / receiving master unit 50, a wireless router (access point) 60, ISPs 90-92, a network (Internet) 95, a cloud server 100, and user terminals (such as a mobile communication terminal 70, a tablet terminal 101, and a notebook PC terminal 102).

[0063] The garage shutter device 1 and the window shutter devices 2-4 are the opening and closing device group shown in Fig. 1, and transmit various signals such as control signals and detection signals (current detectors, voltage detectors, temperature detectors, video signals captured by security cameras, signals detected by motion sensors, etc.) to the transmitting / receiving master unit 50. As described above, the garage shutter device 1 and the window shutter devices 2-4 are connected to the transmitting / receiving master unit 50 by specific low-power radio. Depending on the structural frame of a building such as a house, a building, a factory, or a warehouse, they may be connected by wire or by a mixture of wired and wireless connections. Fig. 5 shows a case where the opening and closing device group is all connected wirelessly, corresponding to Fig. 1.

[0064] The transmitting / receiving master unit 50 receives various signals from the garage shutter device 1 and the window shutter devices 2 to 4, converts the signals into data related to predetermined opening and closing devices, records the data, and transmits the data to the cloud server 100 via a wireless router (access point) 60 and an external network 95. The cloud server 100 is provided with a monitor that displays live the opening and closing device data and video signals transmitted from the transmitting / receiving master unit 50. By visually checking the monitor, it is possible to acquire and recognize video signals captured by a surveillance camera, and to determine the state of the opening and closing devices of which buildings in which areas, and to efficiently and centrally control the opening and closing operations of multiple opening and closing devices installed in separate locations.

[0065] The ISPs (Internet Service Providers) 90, 91, 92 and the network 95 are composed of a mobile communication network (wireless network) and a wired communication network (wired network). The mobile communication network (wireless network) is a communication service network provided by mobile phone service companies such as mobile phone service companies and PHS service companies, and the wired communication network (wired network) is a communication service network provided by public telephone service companies such as fixed-line telephone service companies. The wired communication network (wired network) includes the network 95 connected via the ISP.

[0066] The wireless router (access point) 60 connects the transmitting / receiving parent device 50 to the network 95 via the ISP 90, and has a WiFi function. The cloud server 100 is connected to the network 95 via the ISP 91. The user terminals (mobile communication terminal 70, tablet terminal 101, notebook PC terminal 102) are connected to the wireless router (access point) 60 in infrastructure mode. In addition to the devices described in the embodiments, other devices are also connected to the wireless router (access point) 60 in infrastructure mode.

[0067] Also, user terminals (mobile communication terminal 70, tablet terminal 101, notebook PC terminal 102) can connect to network 95 via ISP 92, which is separate from ISP 90. That is, ISP 90 exists in a location such as a building where garage shutter device 1, window shutter devices 2-4, transmission / reception master device 50, and wireless router (access point) 60 are installed, and is connected there. On the other hand, ISPs 91 and 92 can be connected from remote locations such as a management center, a user's company, or a field office, which are far away from the locations where garage shutter device 1, window shutter devices 2-4, transmission / reception master device 50, and wireless router (access point) 60 are installed.

[0068] In order to connect the wireless router (access point) 60 and the cloud server 100 via the Internet, an ID authentication process must be performed in advance from the transmission / reception master device 50 to the cloud server 100 via the wireless router (access point) 60. This ID authentication process is executed by the user inputting a user ID, password, postal code, email address, etc., using a user terminal (mobile communication terminal 70, tablet terminal 101, and / or notebook PC terminal 102). In this embodiment, the user terminal is in a state where it can be connected to the wireless router (access point) 60 via WiFi, and therefore can be connected to the transmission / reception master device 50 via the wireless router (access point) 60.

[0069] Furthermore, when the user terminal is connected to ISP 92 outside the building, it can be connected to the transmission / reception base unit 50 via the ISP 92, network 95, ISP 90, and wireless router (access point) 60. Furthermore, the user terminal can be connected to the cloud server 100 via the wireless router (access point) 60, ISP 90, network 95, and ISP 91, or via the ISP 92, network 95, and ISP 91. On the other hand, the transmission / reception base unit 50 can be connected to the cloud server 100 via the wireless router (access point) 60, ISP 90, network 95, and ISP 91.

[0070] The transmitting / receiving parent device 50 includes a server information section, a user information section, an ISP information section, an e-mail sending section, and the like for connecting to the network 95 via the wireless router (access point) 60 and the ISP 90. The server information section stores various information such as the URL, login ID, and password of the cloud server 100, and executes the connection to the cloud server 100.

[0071] The user information section stores various information such as user IDs and passwords related to user terminals (notebook PC terminal 102, tablet terminal 101, mobile communication terminal 70), and connects the user terminals to the transmission / reception master device 50. The ISP information section stores information required to connect to the network 95 via the ISP 90, and executes the connection to the network 95.

[0072] The transmission / reception master unit 50 is equipped with an email sending unit and can store an email address input from a user terminal or a remote monitoring center, and can transmit various information, video signals, and the like to the email address via the network 95. The transmission / reception master unit 50 can also transmit various data via the network 95 in response to a request from a user terminal (notebook PC terminal 102, tablet terminal 101, mobile communication terminal 70). The transmission / reception master unit 50 transmits the various data to the cloud server 100 via the network 95 at a predetermined timing, or when the state of the garage shutter device 1 and the window shutter devices 2 to 4 changes, or when a detection signal is detected, for example.

[0073] The transmission / reception master unit 50 checks whether the access request received via the wireless router (access point) 60 matches the user ID and password previously set and registered as the user, and extracts an email address corresponding to the user ID. If the result of the check shows that the user ID and password match those set and registered, the transmission / reception master unit 50 transmits a global IP address or information about a URL including this global IP address to the user terminal, etc. The tablet terminal 101, mobile communication terminal 70, etc. are equipped with a notification function in the terminal itself, so that the received data can be instantly notified to the user. For terminals without a notification function such as the notebook PC terminal 102, the data is transmitted by email, etc.

[0074] When a user uses a user terminal (notebook PC terminal 102, tablet terminal 101, mobile communication terminal 70) to check the status of the garage shutter device 1 and the window shutter devices 2 to 4, the user terminal accesses the transmission / reception master unit 50 based on a global IP address or a URL including a global IP address assigned by the ISP 90. The transmission / reception master unit 50 uses a user ID, password, etc. stored in the user information section to give connection permission to the user terminal. This enables the user terminal to access the transmission / reception master unit 50 and check the status of the garage shutter device 1 and the window shutter devices 2 to 4, detection data, video information, etc.

[0075] After checking the status, detection data, and video information of the garage shutter device 1 and the window shutter devices 2-4, the user terminal transmits a termination request to the transmission / reception master unit 50. Upon receiving this termination request, the transmission / reception master unit 50 disconnects the connection to the ISP 90. Also, if there is no access to the transmission / reception master unit 50 from the communication terminal of the user terminal for a certain period of time or more, the connection to the ISP 90 is also disconnected. This allows the user to obtain and confirm the status, detection data, and video information of the garage shutter device 1 and the window shutter devices 2-4 from the transmission / reception master unit 50 with a simple operation. In the above-mentioned embodiment, the status, detection data, and video information of the garage shutter device 1 and the window shutter devices 2-4 can be accessed simultaneously from multiple user terminals using the transmission / reception master unit 50.

[0076] FIG. 6 is a diagram showing a schematic view of the shooting area of ​​a surveillance camera installed in the garage shutter device 1. As shown in FIG. 1, the garage shutter device 1 has a surveillance camera 14 constituting a network camera system installed at the front upper part of the opening of the garage 10, outside the garage 10. The angle of view of the surveillance camera 14 is about 90 degrees. When the shutter 15, which is an opening / closing member of the garage shutter device 1, is fully opened, the shooting area is the vicinity of the shutter 15 on the outside of the garage 10 and almost the entire area inside the garage 10, as shown in FIG. 6(A). On the other hand, when the shutter 15 of the garage shutter device 1 is fully closed, the shooting area is only the outside of the garage 10, with almost the entire area inside the garage 10 being blocked by the shutter 15, as shown in FIG. 6(B). Therefore, the entire area inside the garage 10 is a non-shooting area.

[0077] The surveillance camera 14 in FIG. 6 is placed outside the shutter room, i.e., outside the garage 10, and the angle of view of the surveillance camera 14 is about 90 degrees, so that the surveillance camera 14 is directed in a direction that allows it to capture the inside (inside) of the garage 10 from the outside (outside) of the garage 10. In addition, when the shutter 15 of the garage shutter device 1 is closed, the closed shutter 15 makes the inside (inside) of the garage 10 a blind spot for the surveillance camera 14. The state of the inside (inside) of the garage 10 when the shutter 15 of the garage shutter device 1 is closing and during the closing operation of the shutter 15 are photographed and recorded in the server 100 via the network, and the recorded video can be played back after the closing operation is completed, i.e., after the recording, to observe whether or not a person is trapped inside the garage 10. As a result, when the shutter 15 of the garage shutter device 1 is closed, the vicinity of the shutter 15 outside the garage 10 is photographed, and the inside (inside) of the garage 10 is not photographed, and it is possible to visually check based on the recorded video whether or not a person is trapped inside the garage 10 when the shutter 15 of the garage shutter device 1 is closed.

[0078] The surveillance camera 34 of the window shutter device 3 is installed on the outside of the building behind the opening of the sliding window, and the shooting area of ​​the surveillance camera 34 is adjusted so as to monitor whether or not there is a person on the balcony 35, so as not to shoot the interior side of the window shutter device 3.

[0079] 7 is a diagram showing an example of a process executed by a surveillance camera of a garage shutter device. This process is executed at a predetermined interrupt timing. In step S71, it is determined whether or not the garage shutter device 1 has started a closing operation from a fully open state. If it has started (yes), the process proceeds to the next step S72, and otherwise the process returns. In step S72, the video captured by the surveillance camera 14 is recorded. In step S73, it is determined whether the closing operation of the garage shutter device 1 has been completed. If it has been completed (yes), the process proceeds to the next step S74. If it has not been completed (no), the process continues to record the video captured by the surveillance camera 14 in step S72.

[0080] In step S74, recording of the video captured by the surveillance camera 14 is stopped. In step S75, the recorded video captured by the surveillance camera 14 is transmitted to a predetermined mobile communication terminal 70. When mobile communication terminal 70 receives the video footage captured by surveillance camera 14, a mark indicating the presence of a recorded image will be displayed on the “camera” icon, as shown in mobile communication terminal 703, and the operator can tap on it to display the recorded image on mobile communication terminal 70.

[0081] In the above embodiment, the case where the video captured by the surveillance camera 14 is recorded on the server 100 via the Internet has been described, but the surveillance camera 14 may record the video information in its built-in memory and distribute it. Also, if the surveillance camera 14 is a type that constantly records video information, it may record timing information of the start of the closing operation of the garage shutter device 1 and each operation during the closing operation, and distribute the video information based on the timing information during playback.

[0082] In the above-described embodiment, a case has been described in which surveillance camera video information is also transmitted and received when a two-way communication state is established between the transceiver handset 13, 33 and the transceiver master unit 50. However, since the amount of data transmitted and received from surveillance cameras is large, a network for surveillance cameras may be incorporated separately from the network for the opening and closing device.

[0083] In the above embodiment, the wireless router (access point) 60 is installed in one place, but the access points may be installed in multiple places in the building. In this case, the access points may be installed in the garage shutter device 1 and the window shutter devices 2 to 4, or in the LAN terminals in the building. When multiple access points are installed, the settings may be made so that connection can be made via each of the access points.

[0084] In the above embodiment, the transmission / reception master unit 50 and the transmission / reception slave units 13, 23, 33, 43 are connected by a specific low-power wireless method, but they may be connected via a LAN line within the building. In the above embodiment, the case where a plurality of switchgears are controlled is described, but when a single switchgear is controlled, the transmission / reception master unit and the transmission / reception slave units may be configured by a single control means without being provided separately.

[0085] In the above embodiment, a shutter curtain that is unrolled in a vertical lifting manner has been described as an example, but the present invention can be applied to a shutter-like opening and closing member that is unrolled in a lateral pulling manner or a horizontal pulling manner. In addition, the present invention can be applied to opening and closing devices such as shutter devices, window shutter devices, blind devices, roller screen devices, drapery devices, sliding door devices, swing door devices, movable partition devices, awning devices, waterproof board devices, gate devices, etc.

[0086] In the above embodiment, the opening dimension of the opening portion is the height dimension because the opening and closing device is used as an example in which the shutter curtain is pulled up and down, but in the case of an opening and closing device that pulls out the shutter curtain horizontally, the opening dimension may be the width dimension. Also, in the case of an awning or curtain device that does not completely close the entire opening, the extension stroke length may be replaced with the opening dimension of the opening. The application software for mobile communication terminals can be freely downloaded from a specified URL. Furthermore, the design and operation method can be easily changed by modifying the application software as needed.

[0087] The mobile communication terminal means described as the mobile communication terminal 70 in the above embodiment does not necessarily have to be designed to be carried around as long as it can perform similar processing and communication using application software, and may be a non-portable device that is usually used as a stationary device or a large, mobile device. For example, a device with a communication function, such as a living room TV with information display and operation functions or a car navigation device installed in a car, may communicate with the transmission / reception base unit 50 using application software and function as a remote control switch. In addition, the mobile communication terminal and application software may be operated virtually on the cloud, and for example, the mobile communication terminal may be a site on the Internet that functions as a remote control switch using application software displayed as a Web page (specific processing and communication with the transmission / reception base unit 50 are performed by a server device that operates and processes the site).
