[0002] Conventionally, there is known a shutter device that opens or closes a shutter curtain by operating an open switch or a close switch on a remote control device. In this shutter device, a user can stop the shutter curtain at any position between the upper limit position and the lower limit position by operating a stop switch while the shutter curtain is moving (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Publication No. 2020-159071 Summary of the Invention [Problem to be solved by the invention]

[0004] However, to stop the shutter curtain at any intermediate position, the user must wait until the moving shutter curtain reaches the desired position and then operate the stop switch, making it difficult to specify the desired intermediate position. In recent years, it has been proposed to automatically operate various devices in a building using a gateway such as a Home Energy Management System (HEMS). In this case, it is necessary to automatically stop the shutter curtain at any intermediate position.

[0005] An object of the present disclosure is to provide an electric opening / closing body device and a control system that can arbitrarily specify the position at which the opening / closing body is stopped from a plurality of intermediate positions. [Means for solving the problem]

[0006] The present disclosure relates to an electric opening / closing body device that includes an opening / closing body, a motor that drives the opening / closing body to open and close, and a control device that controls the drive of the motor to move the opening / closing body to open and close, wherein the control device divides the amount of movement of the opening / closing body when the opening / closing body is moved between an open direction limit position and a closed direction limit position into multiple parts, thereby generating multiple intermediate positions for stopping the opening / closing body between the open direction limit position and the closed direction limit position, and has a position designation information setting unit that sets position designation information for each of the multiple intermediate positions.

[0008] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings. Figures 1 and 2 show an electric shutter device 1 that shields an opening formed in a wall of a building. The electric shutter device 1 is one embodiment of an electric opening / closing device. The electric shutter device 1 is disposed, for example, on the outdoor side of a window W provided in an opening of the building (see Figure 6), and includes a shutter unit 2 and a control device 3 that controls the shutter unit 2.

[0009] The shutter unit 2 has a winding unit 21, a drive unit 22, and a shutter curtain 23. The winding unit 21 is rotated by the drive of a motor 22a (see FIG. 3) provided in the drive unit 22, and is configured to be able to wind up and unwind the shutter curtain 23.

[0010] As shown in Fig. 3, the drive unit 22 has a motor 22a that rotates to rotate the winding unit 21, and a position detection unit 22b. The position detection unit 22b is configured, for example, with a rotary encoder or the like, and outputs detection pulses that are generated as the motor 22a is rotated to the control unit 31. This detects the rotational position of the motor 22a, and the current position of the shutter curtain 23 in the opening / closing direction can be determined from the rotational position of the motor 22a. Information on the rotational position of the motor 22a detected by the position detection unit 22b is stored in the memory unit 33 each time the shutter curtain 23 moves. The winding unit 21, the drive unit 22, and the shutter curtain 23 wound up by the winding unit 21 are arranged inside the housing 20 of the shutter unit 2.

[0011] The shutter curtain 23 is an opening / closing body formed by connecting a plurality of slats 23a, and is placed on the exterior side of the window W. A baseboard 23b is provided at the tip of the shutter curtain 23. When the shutter curtain 23 is rolled up or down by the winding section 21, the baseboard 23b moves upward or downward while being guided by a pair of guide rails 24, 24 provided vertically on the left and right sides of the shutter section 2, thereby opening or closing the opening.

[0012] When the shutter curtain 23 is opened or closed, the motor 22a is driven in the open direction, causing the shutter curtain 23 to be wound up by the winding unit 21. This causes the baseboard 23b to move upward, and the opening to open from the bottom. When the baseboard 23b has moved all the way up to fully open the opening, the shutter curtain 23 is positioned at the open limit position. When the shutter curtain 23 is opened or closed, the motor 22a is driven in the close direction, causing the shutter curtain 23 to be wound down by the winding unit 21. This causes the baseboard 23b to move downward, and the opening to close from the top. When the baseboard 23b has moved all the way down to fully close the opening, the shutter curtain 23 is positioned at the close limit position.

[0013] 2, the control device 3 includes functional units, a control unit 31, a position specification information setting unit 32, a storage unit 33, and a communication unit 34. In FIG. 1, the control device 3 is shown separated from the shutter unit 2, for example, so as to be disposed in a box on the indoor wall, but some or all of the functions of the control device 3 may be disposed in the housing 20 of the shutter unit 2.

[0014] The control unit 31 is configured with a CPU (Central Processing Unit) that controls the electric shutter device 1, and controls the operation of each part of the electric shutter device 1. Specifically, the control unit 31 controls the driving of the motor 22a of the drive unit 22 to rotate the winding unit 21 and open and close the shutter curtain 23. The control unit 31 detects the rotational position of the motor 22a based on the number of pulses detected by the position detection unit 22b. This allows the control unit 31 to obtain position information about the opening and closing directions of the shutter curtain 23.

[0015] The control unit 31 controls the communication unit 34 to communicate with the communication terminal 100. The communication terminal 100 is a terminal associated with the electric shutter device 1, capable of wirelessly transmitting and receiving various types of information to and from the communication unit 34 of the control device 3, and is operated by a user. The communication terminal 100 is a remote control, a smartphone, a tablet terminal, or the like. This allows the control unit 31 to accept various instruction requests to the electric shutter device 1 from the user operating the communication terminal 100. The instruction requests transmitted from the communication terminal 100 include a stop position command to stop the shutter curtain 23 at any intermediate position.

[0016] The position designation information setting unit 32 sets a plurality of intermediate positions between the open direction limit position and the closed direction limit position of the shutter curtain 23, in addition to the open direction limit position and the closed direction limit position. Specifically, the position designation information setting unit 32 divides the movement amount of the shutter curtain 23 when the shutter curtain 23 is moved between the open direction limit position and the closed direction limit position into a plurality of parts. As a result, the position designation information setting unit 32 generates a plurality of intermediate positions for stopping the shutter curtain 23 between the open direction limit position and the closed direction limit position of the shutter curtain 23, and sets position designation information for each of the plurality of intermediate positions. The set position designation information is stored in the storage unit 33.

[0017] The position designation information is also movement information for the shutter curtain 23 for moving the shutter curtain 23 to an arbitrary intermediate position and stopping it there. When the control device 3 receives a stop position command corresponding to an arbitrary intermediate position from the communication terminal 100 via the communication unit 34, the control unit 31 reads out the position designation information corresponding to the stop position command from the storage unit 33, and outputs a drive pulse to the motor 22a so as to move the shutter curtain 23 from its current position to the intermediate position designated by the stop position command and stop it there. This drives the motor 22a to rotate the winding unit 21, and moves the shutter curtain 23 to the intermediate position designated by the stop position command and stops it there. The specific functions of the position designation information setting unit 32 will be described further below.

[0018] The storage unit 33 is configured by a storage device such as an SSD (Solid State Drive) or RAM (Random Access Memory). The storage unit 33 stores operation programs for executing various functions of the electric shutter device 1. Furthermore, the storage unit 33 stores the position designation information set by the position designation information setting unit 32.

[0019] 2, the communication unit 34 has a receiving unit 34a and a transmitting unit 34b. The receiving unit 34a is capable of receiving various instruction requests transmitted from the communication terminal 100 or the like. The transmitting unit 34b is capable of transmitting various information related to the electric shutter device 1 to the communication terminal 100 or the like. The information transmitted from the transmitting unit 34b to the communication terminal 100 or the like includes position information in the opening / closing direction including the current position of the shutter curtain 23, specifically, position information in the opening / closing direction of the baseboard 23b.

[0020] Next, the processing operation of the position designation information setting unit 32 by the control device 3 in the electric shutter device 1 will be described with reference to the flowchart shown in Fig. 4. The processing operation of the position designation information setting unit 32 is executed under the control of the control unit 31 based on a program stored in advance in the storage unit 33, for example, as an initial setting after the electric shutter device 1 is installed at an opening in a building.

[0021] First, in step S1, the control unit 31 checks whether the shutter curtain 23 is completely wound up on the winding unit 21. Here, the explanation is given assuming that the initial setting is performed with the state where the shutter curtain 23 is completely wound up on the winding unit 21 and positioned at the upper limit position in the opening direction as the origin position. If the shutter curtain 23 is not positioned at the upper limit position in the opening direction, the control unit 31 rotates the motor 22a to rotate the winding unit 21 so that the shutter curtain 23 is positioned at the upper limit position in the opening direction. Whether the shutter curtain 23 is positioned at the upper limit position in the opening direction can be detected, for example, from a change in the load on the motor 22a. After it is confirmed that the shutter curtain 23 is positioned at the upper limit position in the opening direction, the processing proceeds to step S2.

[0022] In step S2, motor 22a is driven to rotate take-up unit 21 in the winding down direction, causing shutter curtain 23 to start moving in the closing direction. At the same time, control unit 31 starts detecting the amount of movement of shutter curtain 23 in the closing direction from the origin position. The amount of movement of shutter curtain 23 can be detected by counting the number of drive pulses output to motor 22a. The amount of movement of shutter curtain 23 may also be detected by counting the number of detection pulses by position detection unit 22b. Control unit 31 continuously detects the amount of movement of shutter curtain 23 while shutter curtain 23 is moving in the closing direction. Information on the detected amount of movement is sent to position specification information setting unit 32.

[0023] As the shutter curtain 23 moves in the closing direction, the baseboard 23b of the shutter curtain 23 eventually reaches the lower end position, and the shutter curtain 23 is thereby positioned at the closing direction limit position where the opening is fully closed. After the shutter curtain 23 starts moving in the closing direction, the control unit 31 determines in step S3 whether the shutter curtain 23 has been positioned at the closing direction limit position, for example, by monitoring changes in the load on the motor 22a. If the shutter curtain 23 has not yet been positioned at the closing direction limit position (step S3; NO), the shutter curtain 23 continues to move in the closing direction until it is detected that the shutter curtain 23 has been positioned at the closing direction limit position. If the shutter curtain 23 has been positioned at the closing direction limit position (step S3; YES), the processing proceeds to step S4.

[0024] In step S4, control unit 31 stops the rotational driving of motor 22a to stop the movement of shutter curtain 23 in the closing direction, and ends detection of the amount of movement of shutter curtain 23. Thereafter, the process proceeds to step S5.

[0025] In step S5, the position designation information setting unit 32 calculates the amount of movement of the shutter curtain 23 when it moves from the open limit position to the close limit position from the count value of the drive pulses of the motor 22a detected when the shutter curtain 23 moves from the open limit position to the close limit position, or the amount of rotation of the motor 22a detected by the count value of the detection pulses by the position detection unit 22b, and divides the amount of movement into multiple parts. Specifically, as shown in FIG. 5, the position designation information setting unit 32 divides the amount of rotation of the motor 22a into 100 parts, with the open limit position being 0 and the close limit position being 1000, and the range between these two positions being 10, 20, 980, 990, and so on. The numerical values ​​obtained by dividing the amount of rotation of the motor 22a into 100 parts are position designation information corresponding to the open limit position, the close limit position, and an intermediate position between the open limit position and the close limit position, respectively. These pieces of position designation information indicate the value of the rotation amount of the motor 22a required to move the shutter curtain 23 from the open direction limit position, which is the origin position. After the position designation information setting unit 32 has generated 100 pieces of position designation information, the process proceeds to step S6.

[0026] In step S6, the control unit 31 associates the generated 100 pieces of position designation information with intermediate position commands of 0 to 100 for designating stop positions, as shown in Fig. 5, and stores them in the storage unit 33. This completes the initial setting.

[0027] In this way, the position designation information setting unit 32 sets position designation information corresponding to a plurality of intermediate positions between the open direction limit position and the close direction limit position of the shutter curtain 23, so that the electric shutter device 1 can automatically position the shutter curtain 23 at any designated intermediate position from the plurality of intermediate positions simply by receiving any intermediate position command as a stop position command transmitted from the communication terminal 100. The user can position the shutter curtain 23 at any intermediate position with a single action of transmitting the intermediate position command from the communication terminal 100. Because the user does not need to perform a stop operation for the shutter curtain 23, it is also possible to automatically move the shutter curtain 23 to any intermediate position at a designated time by using, for example, a timer function provided in the communication terminal 100 or the control device 3.

[0028] In the position designation information setting unit 32, the amount of movement of the shutter curtain 23 is not limited to being detected by the amount of rotation of the motor 22a. The amount of movement of the shutter curtain 23 may also be detected by the operating time of the motor 22a when moving the shutter curtain 23. In this way, as shown in Fig. 6, for example, the position designation information setting unit 32 may set the motor operating time as 0 seconds for the open direction limit position and 50 seconds for the closed direction limit position, and divide the interval between these into 100 intervals such as 0.5 seconds, 1 second, 49 seconds, and 49.5 seconds.

[0029] In the position designation information setting unit 32, the amount of movement of the shutter curtain 23 may be detected by the distance the shutter moves when the shutter curtain 23 moves. The shutter movement distance can be detected by the rotation position of the motor 22a detected by the position detection unit 22b provided in the drive unit 22. In this way, the position designation information setting unit 32 may, for example, divide the shutter movement distance by 100, with the open direction limit position being 0 and the close direction limit position being 1000, as shown in FIG.

[0030] Because the shutter curtain 23 is wound up by the winding unit 21, the outer diameter of the wound shutter curtain 23 varies depending on the position of the baseboard 23b in the opening / closing direction, and the amount of movement of the shutter curtain 23 wound up by or unwound from the winding unit 21 per rotation of the motor 22a changes. As a result, the closer the shutter curtain 23 is to the limit position in the opening direction, the greater the amount of movement of the shutter curtain 23 per rotation of the motor 22a, and the closer the shutter curtain 23 is to the limit position in the closing direction, the smaller the amount of movement of the shutter curtain 23 per rotation of the motor 22a, resulting in an error in the amount of movement depending on the position of the shutter curtain 23 in the opening / closing direction. Therefore, if the error in the amount of movement of the shutter curtain 23 is not negligible, the drive pulses of the motor 22a or the detection pulses of the position detector 22b between adjacent intermediate positions may not be set to a constant value, but the drive pulses or detection pulses may be varied in consideration of the amount of winding of the shutter curtain 23 wound up by the winding unit 21. 7, a displacement is applied according to the position of the shutter curtain 23 in the opening / closing direction, and the value of the movement distance between adjacent intermediate positions changes according to the displacement. This makes it possible to make the actual movement distance of the shutter curtain 23 at each intermediate position approximately constant, regardless of the amount of winding of the shutter curtain 23.

[0031] The intermediate position between the open limit position and the closed limit position is not limited to being divided into 100. The number of divisions into the intermediate position can be set appropriately depending on the vertical size of the shutter unit 2, etc.

[0032] Next, specific processing operations of the control device 3 when moving the shutter curtain 23 to the intermediate position in the electric shutter device 1 will be described with reference to FIGS.

[0033] The control unit 31 executes a position designation operation to move the shutter curtain 23 to the intermediate position. This position designation operation is shown in Fig. 8. First, in step S11, the control unit 31 checks the intermediate position command from the communication terminal 100 input to the receiving unit 34a of the communication unit 34.

[0034] The intermediate position command can be input by the user touching the operation screen 110 of the communication terminal 100, for example, as shown in Fig. 9. Fig. 9 shows the operation screen 110 for specifying the shutter position. An image 111 of the shutter unit 2 is displayed on the operation screen 110. The user can arbitrarily specify the position of the shutter curtain 23 in the opening / closing direction by swiping a portion of the shutter curtain 23 in the image 111 of the shutter unit 2 with a finger.

[0035] An opening degree display section 112 of the shutter curtain 23 is displayed below the image 111 of the shutter section 2. The opening degree display section 112 displays a numerical value of the opening degree of the shutter curtain 23 specified by the user swiping the image 111. The numerical value displayed in this opening degree display section 112 corresponds to the intermediate position command shown in FIGS. 5 to 7.

[0036] Below the opening degree display unit 112, an up button 113a, a down button 113b, and an OK button 113c are displayed, which function when the user taps with their finger. Instead of swiping with their finger over the shutter curtain 23 in the image 111, the user can tap the up button 113a or the down button 113b to arbitrarily change the opening degree displayed on the opening degree display unit 112. After setting the shutter curtain 23 to a desired opening degree by swiping the image 111 or tapping the up button 113a or the down button 113b, the user taps the OK button 113c, and the intermediate position command "50", which is the stop position command specified by the user, is input from the communication terminal 100 to the control device 3. After the control unit 31 confirms that the intermediate position command "50" has been input, the process proceeds to step S12.

[0037] In step S12, the control unit 31 checks the current position of the shutter curtain 23. This is because the control unit 31 moves the shutter curtain 23 from the current position as the start point of the movement toward the intermediate position. Thereafter, the process proceeds to step S13.

[0038] In step S13, the control unit 31 determines whether or not the current position of the shutter curtain 23 was acquired in step S12. If the current position was acquired in step S12 (step S13; YES), the process proceeds to step S14. On the other hand, if the current position was not acquired in step S12 for some reason (step S13; NO), the process proceeds to step S15.

[0039] In step S14, the control unit 31 moves the shutter curtain 23 from the current position to the intermediate position specified by the communication terminal 100. In detail, the control unit 31 calculates the amount of motor rotation required to move the shutter curtain 23 from the current position to the intermediate position corresponding to the intermediate position command "50", which is the opening degree specified by the communication terminal 100.

[0040] For example, if the current position of the shutter curtain 23 is located at a position corresponding to the intermediate position command "4" shown in Fig. 5, the control unit 31 calculates the difference "460" between the amount of motor rotation "40" corresponding to the intermediate position command "4" and the amount of motor rotation "500" corresponding to the intermediate position command "50". As a result, the control unit 31 outputs 460 pulses as drive pulses to the motor 22a, or moves and stops the shutter curtain 23 from the current position corresponding to the intermediate position command "4" to a position corresponding to the intermediate position command "50" until the position detection unit 22b detects 460 pulses as detection pulses. As a result, the shutter curtain 23 stops when the baseboard 23b reaches approximately the center position in the vertical direction, as shown in Fig. 10, and is positioned so that only half of the opening is opened.

[0041] On the other hand, when the process proceeds to step S15, the control unit 31 executes a current position confirmation process to confirm the current position of the shutter curtain 23. The current position confirmation process is a process in which the control unit 31 returns the shutter curtain 23 to its origin position once when the control unit 31 is no longer able to detect the current position of the shutter curtain 23. This current position confirmation process will be described with reference to the flowchart shown in FIG.

[0042] First, in step S151, control unit 31 drives motor 22a to rotate so as to position shutter curtain 23 at the opening limit position, which is the origin position, and moves shutter curtain 23 in the opening direction. Thereafter, the process proceeds to step S152.

[0043] In step S152, the control unit 31 determines whether the shutter curtain 23 moved in step S151 has reached the open limit position. If the shutter curtain 23 has reached the open limit position (step S152; YES), the process proceeds to step S153. If the shutter curtain 23 has not reached the open limit position (step S152; NO), the process continues until the shutter curtain 23 reaches the open limit position.

[0044] In step S153, the control unit 31 stops the rotational driving of the motor 22a and stops the movement of the shutter curtain 23. After that, the process proceeds to step S154.

[0045] In step S154, the control unit 31 acquires the origin position of the shutter curtain 23 placed at the open limit position, i.e., the rotational position of the motor 22a detected by the position detection unit 22b when the shutter curtain 23 is placed at the open limit position, as the current position, and stores it in the storage unit 33. Thereafter, the process proceeds to step S14 of the flowchart shown in FIG.

[0046] According to this, even if, for example, an abnormality such as a power outage occurs while the electric shutter device 1 is in operation and the current position of the shutter curtain 23 cannot be detected, and the control unit 31 is unable to confirm the current position of the shutter curtain 23 when it starts to move to the intermediate position, it is possible to determine the current position of the shutter curtain 23 by temporarily returning the shutter curtain 23 to its origin position.

[0047] The origin position of the shutter curtain 23 may be the closing direction limit position. In this case, in step S151 of the current position confirmation process, the shutter curtain 23 is moved in the closing direction.

[0048] Fig. 12 shows a schematic configuration of a control system A when the electric shutter device 1 is incorporated into a home energy management system (HEMS). The control system A is a home network system that enables a user to remotely control the electric shutter device 1 and other devices such as home appliances (not shown) installed in a building 200 via an internet line NW using a communication terminal 100 such as a smartphone or tablet terminal. Fig. 12 shows only one electric shutter device 1 as a device in the building 200, but multiple electric shutter devices 1 may be installed in the building 200.

[0049] The building 200 is provided with an environment detection unit 4 as a device. The environment detection unit 4 is composed of various sensors for detecting environmental information around the electric shutter device 1. Specifically, the environment detection unit 4 includes an illuminance sensor that detects the illuminance on the indoor side of the electric shutter device 1, a temperature sensor that detects the temperature on the indoor side of the electric shutter device 1, a humidity sensor that detects the humidity on the indoor side of the electric shutter device 1, a gas sensor that detects the concentration of gases such as carbon dioxide on the indoor side of the electric shutter device 1, a weather sensor that detects weather information on the outdoor side of the electric shutter device 1, a clock that detects the current time, etc. The weather sensor may include a temperature sensor, a humidity sensor, an illuminance sensor, a rainfall sensor that detects the amount of rainfall, a wind speed sensor that detects wind speed, a wind direction sensor that detects wind direction, etc.

[0050] The environment detection unit 4 may have only one of these various sensors, or may have two or more of them. The environment detection unit 4 may also be configured as a multi-function sensor having the functions of two or more of these various sensors.

[0051] The environmental information may be acquired via the Internet line NW, as shown in FIG. 12, instead of or in addition to that acquired by the environment detection unit 4.

[0052] 12, the control system A includes a communication interface 210. The communication interface 210 includes a router 211 and a gateway 212. The communication interface 210 is installed in a building 200, for example.

[0053] The router 211 connects the communication interface 210 to the Internet line NW. The router 211 is further connected to the gateway 212 via a wireless or wired connection. The router 211 relays the transmission of information between the Internet line NW and the gateway 212.

[0054] Various devices, including the electric shutter device 1 and the environment detection unit 4, installed in the building 200, are connected to the gateway 212 via wireless or wired connections. As shown in FIG. 13 , the gateway 212 has a communication unit 212a and a shutter control unit 212b. These functional units are realized in the gateway 212 by hardware, such as a central processing unit (CPU), executing a program stored in a storage device (not shown). Some or all of these functional units may be realized by hardware, such as a large-scale integrated circuit (LSI), an application-specific integrated circuit (ASIC), a field-programmable gate array (FPGA), or a graphics processing unit (GPU), or may be realized by a combination of software and hardware.

[0055] The communication unit 212a transmits and receives information wirelessly or via wires to and from various devices including the electric shutter device 1 and the environment detection unit 4 installed in the building 200. The transmission paths between the communication unit 212a and the various household equipment may use, for example, a low-power wide-area network (LPWAN) or short-range wireless communication standards such as ZigBee (registered trademark), WiFi (registered trademark), Bluetooth (registered trademark), etc. The transmission paths between the communication unit 212a and the various household equipment do not all have to be the same transmission path.

[0056] The communication unit 212a has communication functions for a plurality of different communication methods. Some of the various devices, including the electric shutter device 1 and the environment detection unit 4, have wireless communication methods that differ from other devices. The communication unit 212a is configured to be able to communicate with each of the plurality of devices, even if there are multiple devices that use different wireless communication methods among the multiple devices.

[0057] The shutter control unit 212b is an opening / closing body control unit. Based on the environmental information acquired from the environment detection unit 4 via the communication unit 212a or the environmental information acquired via the Internet line NW, the shutter control unit 212b determines whether the shutter curtain 23 should be positioned at the open direction limit position, the close direction limit position, or a plurality of intermediate positions, and generates an intermediate position command to move the shutter curtain 23.

[0058] For example, if the environmental information is illuminance detected by an illuminance sensor, the shutter control unit 212b determines whether to move the shutter curtain 23 to an intermediate position or the closing limit position depending on the magnitude of the detected value when sunlight enters the room. If the environmental information is temperature, humidity, or gas concentration detected by a temperature sensor, humidity sensor, or gas sensor, the shutter control unit 212b determines whether to move the shutter curtain 23 to an intermediate position or the closing limit position for ventilation depending on the magnitude of the detected value. If the environmental information is rainfall amount, wind speed, or wind direction detected by a rainfall sensor, wind speed sensor, or wind direction sensor, the shutter control unit 212b determines whether to move the shutter curtain 23 to an intermediate position or the closing limit position depending on the detected value to prevent rain or wind from blowing into the room. Furthermore, if the environmental information is time measured by a clock, the shutter control unit 212b determines whether to move the shutter curtain 23 to an intermediate position or the closing limit position depending on the time, i.e., the sunset.

[0059] When a plurality of electric shutter devices 1 are installed in the building 200, the shutter control unit 212b determines that the shutter curtain 23 should be moved for each of the plurality of electric shutter devices 1. For example, the shutter control unit 212b can select the electric shutter device 1 for which the shutter curtain 23 should be moved, from among the plurality of electric shutter devices 1, according to the wind direction detected by a wind direction sensor.

[0060] When the environmental information acquired via the environment detection unit 4 or the Internet line NW is detected by two or more of the above-mentioned various sensors, the shutter control unit 212b may combine the detection values ​​of each sensor and determine that the shutter curtain 23 should be moved to any intermediate position, the open direction limit position, or the closed direction limit position.

[0061] The shutter control unit 212b has a data map that associates each piece of environmental information with an intermediate position command, which is a stop position instruction, in order to generate an intermediate position command for moving the shutter curtain 23. An example of this data map will be described with reference to FIG. 14. FIG. 14 shows a data map in which the environmental information is wind speed detected by a wind speed sensor. The smaller the wind speed, the smaller the value of the intermediate position command, and therefore the shutter curtain 23 is positioned at or near the open direction limit position. The greater the wind speed, the larger the value of the intermediate position command, and therefore the shutter curtain 23 is positioned at or near the close direction limit position.

[0062] The intermediate position command generated by the shutter control unit 212b is transmitted via the communication unit 212a to the communication unit 34 in the control device 3 of the electric shutter device 1. The control unit 31 of the control device 3 in the electric shutter device 1 outputs a drive pulse to the motor 22a of the drive unit 22 based on the intermediate position command received via the gateway 212, and moves the shutter curtain 23 to the intermediate position corresponding to the intermediate position command.

[0063] Next, a specific processing operation by the gateway 212 in the control system A will be described with reference to the flowchart shown in FIG.

[0064] First, in step S21, the shutter control unit 212b acquires environmental information from the environment detection unit 4 or the Internet line NW at a preset timing via the communication unit 212a. After the environmental information is acquired, the process proceeds to step S22.

[0065] In step S22, based on the acquired environmental information, the shutter control unit 212b determines an intermediate position command for moving the shutter curtain 23. For example, if the acquired environmental information is wind speed, based on the data map shown in Fig. 14, the shutter control unit 212b determines an intermediate position command corresponding to the acquired wind speed. After the intermediate position command is determined, the process proceeds to step S23.

[0066] In step S23, the shutter control unit 212b transmits the determined intermediate position command via the communication unit 212a to the control device 3 of the electric shutter device 1. This completes the processing by the gateway 212.

[0067] The control device 3 of the electric shutter device 1, which receives the intermediate position command from the gateway 212, moves the shutter curtain 23 to the specified intermediate position and stops it according to the flowchart shown in Figure 8, as described above.

[0068] According to this control system A, the shutter curtain 23 of the electric shutter device 1 can be automatically positioned at an optimum position in accordance with environmental information without relying on user operation.

[0069] In the control system A, the control device 3 of the electric shutter device 1 is configured to, but is not limited to, control the shutter curtain 23 from start to stop of movement after an intermediate position command is input from the gateway 212. The control system A may also be configured to control the start and stop of movement of the shutter curtain 23 from the gateway 212. In this case, the shutter control unit 212b of the gateway 212 has information on the movement amount of the shutter curtain 23 corresponding to the intermediate position command shown in, for example, FIGS.

[0070] Fig. 16 shows a flowchart for controlling the start and stop of movement of the shutter curtain 23 from the gateway 212. First, in step S31, the shutter control unit 212b of the gateway 212 determines and generates an intermediate position command from the acquired environmental information according to the flowchart shown in Fig. 15. The generated intermediate position command is saved in a storage device (not shown) in the shutter control unit 212b. Then, in step S32, the shutter control unit 212b of the gateway 212 transmits, via the communication unit 212a to the control device 3 of the electric shutter device 1, an instruction to start moving the shutter curtain 23 in the opening direction or closing direction corresponding to the generated intermediate position command.

[0071] In step S33, the control device 3 receives the movement start instruction transmitted from the gateway 212 via the receiving unit 34a of the communication unit 34, and based on the movement start instruction, starts moving the shutter curtain 23. After the movement of the shutter curtain 23 has started, in step S34, the control unit 31 of the control device 3 transmits, to the gateway 212, via the transmitting unit 34b of the communication unit 34, position information on the current position of the shutter curtain 23, which is detected each time by the position detecting unit 22b.

[0072] In step S35, the gateway 212 receives, via the communication unit 212a, the position information transmitted from the control device 3. Thereafter, in step S36, the shutter control unit 212b of the gateway 212 detects that the shutter curtain 23 has reached the position specified by the intermediate position command by monitoring the position information received each time the shutter curtain 23 is moving and the information on the amount of movement of the shutter curtain 23 corresponding to the intermediate position command shown in Figures 5 to 7. Thereafter, in step S37, the shutter control unit 212b transmits, via the communication unit 212a, to the control device 3 of the electric shutter device 1, a stop instruction to stop the movement of the shutter curtain 23.

[0073] In step S38, the control device 3 receives a stop instruction from the gateway 212 via the receiving unit 34a of the communication unit 34. Then, in step S39, the control unit 31 of the control device 3 stops outputting drive pulses to the motor 22a and stops the movement of the shutter curtain 23. As a result, the shutter curtain 23 is placed at a position corresponding to the intermediate position command transmitted from the gateway 212 in step S31.

[0074] In this way, when the start and stop of movement of the shutter curtain 23 is controlled from the gateway 212, the functional unit of the position designation information setting unit 32 provided in the control device 3 of the electric shutter device 1 is also provided in the gateway 212. In this case, the functional unit of the position designation information setting unit 32 may be provided only in the gateway 212.

[0075] In the above embodiment, an electric shutter device 1 disposed on the exterior side of a window W has been exemplified as an electric opening / closing device. However, the electric opening / closing device of the present disclosure is not limited to such an electric shutter device 1, and may be any device provided with an opening / closing body that is electrically operated to open and close. The electric opening / closing device of the present disclosure is applicable to devices that are installed in an opening and operate, such as windows, doors, sliding doors, and all other opening / closing bodies that can be electrically operated. Similarly, the electric opening / closing device of the present disclosure is also applicable to devices that electrically open and close sunshade products that are installed in openings, such as blinds, shades, roller curtains, and awnings. The opening and closing direction of the opening / closing body is not limited to the vertical direction, and may be any direction, such as the horizontal direction.

[0076] The electric opening / closing body device of the present disclosure may be a device that electrically opens and closes a window as an opening / closing body provided in an opening of a building. The window can be any window that opens and closes, such as a sliding window, a casement window, or a double-hung window, without any restrictions. Figures 17 and 18 show an example in which the opening / closing body that opens and closes electrically is a casement window Wa provided in an opening formed in a wall 201 of a building 200. The opening and closing operation of the casement window Wa is controlled so that it is positioned at an arbitrary intermediate position based on an intermediate position command transmitted from the communication terminal 100, as in the case of the electric shutter device 1.

[0077] Although not shown, the casement window Wa may be provided in the control system A shown in Fig. 12 together with the electric shutter device 1. In this case, the opening and closing operation of the casement window Wa may be controlled based on an intermediate position command transmitted from the communication terminal 100 operated by the user, as in the case of the electric shutter device 1, or may be controlled based on an intermediate position command generated by the shutter control unit 212b of the gateway 212.

[0078] When the casement window Wa is controlled based on an intermediate position command generated by the shutter control unit 212b of the gateway 212, the position of the shutter curtain 23 may be controlled based on acquired environmental information. For example, when the environmental information is wind speed detected by a wind speed sensor, if the wind speed is low, the casement window Wa can be automatically controlled to be positioned at an intermediate position where it is widely opened toward the outside of the room, as shown in Fig. 17, and if the wind speed is high, the casement window Wa can be automatically controlled to be positioned at an intermediate position where it is slightly opened toward the outside of the room, as shown in Fig. 18.

[0079] Although the preferred embodiments of the present disclosure have been described above, the electric opening / closing body device and control system of the present disclosure are not limited to the above-described embodiments and can be modified as appropriate.

[0080] This embodiment provides the following advantages. Specifically, the electric shutter device 1 of this embodiment includes a shutter curtain 23, a motor 22a that drives the shutter curtain 23 to open and close, and a control device 3 that controls the drive of the motor 22a to open and close the shutter curtain 23. The control device 3 divides the amount of movement of the shutter curtain 23 when the shutter curtain 23 is moved between the open limit position and the closed limit position into multiple parts, thereby generating multiple intermediate positions for stopping the shutter curtain 23 between the open limit position and the closed limit position, and includes a position designation information setting unit 32 that sets position designation information for each of the multiple intermediate positions. This allows the position at which the shutter curtain 23 is stopped to be arbitrarily designated from the multiple intermediate positions. This improves the convenience of the electric shutter device 1.

[0081] The electric shutter device 1 of this embodiment has a position detection unit 22b that detects the current position of the shutter curtain 23 and a receiver 34a that receives an intermediate position command to stop the shutter curtain 23 at one of a plurality of intermediate positions, and the control device 3 drives the motor 22a based on the position designation information corresponding to the intermediate position command received by the receiver 34a and the current position acquired from the position detection unit 22b so that the shutter curtain 23 moves from the current position to the intermediate position corresponding to the intermediate position command and stops there. In this way, the shutter curtain 23 can be moved from the current position to the intermediate position.

[0082] In the electric shutter device 1 of this embodiment, when the current position of the shutter curtain 23 cannot be acquired, the control device 3 drives the motor 22a to move the shutter curtain 23 to the open limit position or the closed limit position, and acquires the open limit position or the closed limit position as the current position of the shutter curtain 23. In this way, even if the current position of the shutter curtain 23 cannot be detected due to an abnormality such as a power outage occurring while the electric shutter device 1 is in operation, and the control unit 31 is unable to confirm the current position of the shutter curtain 23 when it starts to move to the intermediate position, it is possible to determine the current position of the shutter curtain 23 by returning the shutter curtain 23 to the open limit position or the closed limit position.

[0083] The control system A of this embodiment is a control system A comprising the above-mentioned electric shutter device 1 and a gateway 212 communicably connected to the control device 3 of the electric shutter device 1, and the gateway 212 has a shutter control unit 212b that generates an intermediate position command to be sent to the control device 3. With this, the position at which the shutter curtain 23 of the electric shutter device 1 is stopped can be arbitrarily designated from a plurality of intermediate positions by the gateway 212 without any user operation.

[0084] In the control system A of this embodiment, the gateway 212 includes a communication unit 212a that acquires environmental information about the surroundings of the electric shutter device 1, and the shutter control unit 212b generates an intermediate position command based on the environmental information acquired from the communication unit 212a. This makes it possible to automatically position the shutter curtain 23 of the electric shutter device 1 at an optimal position according to the environmental information without relying on user operation.

[0085] In the control system A of this embodiment, the shutter control unit 212b has a data map in which intermediate position commands corresponding to environmental information are preset, and generates the intermediate position commands based on the data map. This makes it possible to easily generate intermediate position commands corresponding to environmental information.
