Description

Technical Field

[0001] The present invention relates to an electric shading device, an electric shading device system, and a shading device alignment method, and particularly to an electric shading device, an electric shading device system, and a shading device alignment method that can automatically align between a plurality of lower beams of a plurality of electric shading devices.

Background Art

[0002] With the development of science and technology, when a user wants to give the same light-shielding height to a plurality of windows of the same height for currently commercially available electric shading devices, the user only needs to operate a wireless remote control device to issue a wireless control command, so that the electric shading devices in the same surface direction or the same group of the building can execute the same operation simultaneously, thereby eliminating the trouble that the user has to control each electric shading device one by one. However, since the wireless remote control device and the electric shading device communicate with each other by wireless signals, when the distance between the wireless remote control device and the electric shading device is far or blocked by furniture in the middle, a difference occurs in the timing when each electric shading device receives the wireless control command. As a result, after a plurality of electric shading devices in the same surface direction or the same group of the building stop moving, the lower beams of each electric shading device remain at different heights and are not aligned with each other, so that the light-shielding heights of each window are different, resulting in a messy visual effect. In particular, when the type of the electric shading device is a day-night shading device provided with intermediate beams and lower beams, and the plurality of intermediate beams and lower beams of a plurality of electric shading devices cannot be aligned with each other, the visual effect deteriorates further. And in order to adjust the visual effect of the shading device's light shielding, the user needs to finely adjust the height of each electric shading device individually again and again to align the light-shielding heights of each shading device, and instead, the convenience of the original group control is lost.

[0003] If multiple lower beams and / or intermediate beams of multiple motorized shielding devices within the same plane or group of buildings are not aligned with each other when they are stopped or stationary, it will appear mismatched and unsightly to the user. Therefore, there is a need to provide a technical solution that can automatically align the multiple lower beams and / or intermediate beams of multiple motorized shielding devices within the same group. [Overview of the project] [Problems that the invention aims to solve]

[0004] As can be understood from the above description, the present invention aims to provide a groundbreaking alignment technology for motorized shielding devices, primarily by transmitting alignment packets to other motorized shielding devices when multiple motorized shielding devices within the same group are stopped or stationary. Each motorized shielding device then makes a decision based on its own current position of the lower beam and / or mid-beam, as well as the position of the lower beam and / or mid-beam of the other motorized shielding devices that have received the decision. Based on the result of this decision, it determines whether to move the lower beam and / or mid-beam, and the position to which the lower beam and / or mid-beam will stop after moving, thereby achieving the objective of automatic alignment of the lower beam and / or mid-beam. [Means for solving the problem]

[0005] Based on one object of the present invention, in one aspect of the present invention, a first motorized shielding device is provided, comprising an upper beam, a lower beam, a lower beam drive assembly, a control device, and a power supply unit. The lower beam is located below the upper beam and is driven to move between an upper lower beam upper limit position and a lower lower beam lower limit position relative to the upper beam. The lower beam drive assembly comprises a lower beam motor and a lower beam encoder, the lower beam encoder detecting the rotation of the lower beam motor and generating a lower beam encoder signal representing the current position of the lower beam. The control device is electrically connected to the lower beam motor and the lower beam encoder and is used to control the lower beam motor to move the lower beam and to receive the lower beam encoder signal from the lower beam encoder. The power supply unit is electrically connected to the lower beam motor, the control device, and the lower beam encoder. When the control device receives a specific remote control command, it transmits a first alignment packet to the second motorized shielding device containing information about the current position of the lower beam when at least the lower beam of the first motorized shielding device is stopped or stationary, and receives a second alignment packet from the second motorized shielding device containing information about the current position of the lower beam when at least the lower beam of the second motorized shielding device is stopped or stationary, and controls the lower beam motor to align the lower beam based on the first and second alignment packets.

[0006] Based on one object of the present invention, another aspect of the present invention provides a method for aligning shielding devices used in a first motorized shielding device and a second motorized shielding device. The shielding device alignment method according to this embodiment includes the steps of: the first motorized shielding device transmitting a first alignment packet to a second motorized shielding device containing information about the current position of the lower beam of the first motorized shielding device when the lower beam of the first motorized shielding device is stopped or stationary, after the control device of the second motorized shielding device has received a specific remote control command; the second motorized shielding device transmitting a second alignment packet to the first motorized shielding device containing information about the current position of the lower beam of the second motorized shielding device when the lower beam of the second motorized shielding device is stopped or stationary, after the control device of the second motorized shielding device has received a specific remote control command; the first motorized shielding device aligns the lower beam of the first motorized shielding device by controlling the lower beam motor of the first motorized shielding device based on the first alignment packet and the second alignment packet; and the second motorized shielding device aligns the lower beam of the second motorized shielding device by controlling the lower beam motor of the second motorized shielding device based on the first alignment packet and the second alignment packet.

[0007] Based on one object of the present invention, another embodiment of the present invention provides an electric shielding system comprising the first electric shielding device and the second electric shielding device. In the electric shielding system according to this embodiment, the second electric shielding device is wirelessly connected to the first electric shielding device. [Effects of the Invention]

[0008] As described above, compared to conventional technologies, the electric shielding device, system, and shielding device alignment method provided by the present invention can align the lower beam and / or intermediate beam when multiple electric shielding devices are stopped or stationary. Therefore, it is possible to avoid the hassle of adjustments required when aligning the lower beam and / or intermediate beam by individually controlling multiple electric shielding devices one by one, and to avoid the transmission of multiple control signals associated with adjustments.

[Figure 10] This is a flowchart illustrating a method for aligning a shielding device according to one embodiment of the present invention. [Modes for carrying out the invention]

[0010] To enable automatic alignment of the lower beam and / or mid-beam after multiple motorized shielding devices within the same group in a shielding device system have stopped, the multiple motorized shielding devices according to the present invention perform an automatic alignment method based on transmission packets and transmit alignment packets containing information about the current position of the lower beam and / or mid-beam of the motorized shielding device itself to the other motorized shielding devices. Each motorized shielding device then determines whether to move its lower beam and / or mid-beam, as well as the direction and distance of movement of the lower beam and / or mid-beam, based on its own alignment packet and the alignment packets received from the multiple other motorized shielding devices, thereby enabling the lower beam and / or mid-beam of the multiple motorized shielding devices to align with each other. The transmission method for transmitting the above alignment packets may be broadcast, multicast, or unicast. When multicast or unicast is used, it is usually necessary to set the address of each motorized shielding device, for example, an Internet Protocol address (IP address), but it is not limited to these, and motorized shielding devices within the same group must be aware of each other's addresses. This allows the motorized shielding device to smoothly transmit alignment packets to other motorized shielding devices, and in the case of unicast, this is applicable only when the motorized shielding device system consists of two motorized shielding devices. Furthermore, to improve alignment accuracy, multiple motorized shielding devices within the same group can also perform an alignment method based on the smallest scale division. Possible embodiments of the present invention will be described in detail below with reference to the drawings, but it should be noted that the details of the following embodiments are not intended to limit the scope of the claims asserted by the present invention, but are merely intended to make them easier for a person with general skill in the art to understand.

[0011] First, referring to Figures 1 and 2, Figure 1 is a schematic diagram showing a first motorized shielding device according to one embodiment of the present invention, and Figure 2 is a schematic diagram showing an enlarged view of the lower beam motor and control device in the upper beam of the first motorized shielding device according to one embodiment of the present invention. The first motorized shielding device 1 comprises an upper beam 10, a lower beam 12 provided below the upper beam 10, and a shielding material 11 connected between the upper beam 10 and the lower beam 12. The internal space of the upper beam 10 houses a lower beam motor 101, a control device 106, a lower beam encoder 105, a lower beam winding shaft 102, and a power supply unit 103. The power supply unit 103 is electrically connected to the lower beam motor 101, the control device 106, and the lower beam encoder 105. The control device 106 is electrically connected to the lower beam motor 101 and the lower beam encoder 105, and sets the height position of the upper limit of the lower beam to P1 and the height position of the lower limit of the lower beam to P2 (see Figure 4 simultaneously). The lower beam motor 101, the lower beam winding shaft 102, and the lower beam encoder 105 constitute a lower beam drive assembly, which can move the lower beam 12 relative to the upper beam 10 between a height position P1 at the upper limit of the lower beam and a height position P2 at the lower limit of the lower beam.

[0012] The power supply unit 103 is used to supply DC power to the lower beam motor 101, the control device 106, and the lower beam encoder 105. The power supply unit 103 may be a rechargeable secondary battery, a replaceable primary battery, or an AC-DC adapter circuit connected to a commercial power source, but the present invention is not limited to these. The lower beam winding shaft 102 is connected to the lower beam motor 101, and a lower beam drive shaft 104 is further arranged in the internal space of the upper beam 10 of the first electric shielding device 1, connected between the lower beam winding shaft 102 and the lower beam motor 101. In this embodiment, there are two lower beam winding shafts 102, and the two lower beam winding shafts 102 are connected to each other by the lower beam drive shaft 104, so that the two lower beam winding shafts 102 rotate synchronously. The number of lower beam cords 13 corresponds to the number of lower beam winding shafts 102, but the present invention is not limited to these numbers. One end of the lower beam cord 13 is connected to the lower beam winding shaft 102, and the other end of the lower beam cord 13 is fixed to the lower beam 12 by passing through the shielding material 11. When the lower beam motor 101 rotates, it rotates the lower beam winding shaft 102 via the lower beam drive shaft 104, thereby winding or releasing the lower beam cords 13 connected to the lower beam winding shaft 102. When the lower beam cords 13 are wound onto the lower beam winding shaft 102 or released from the lower beam winding shaft 102, the lower beam 12 can be moved between the height position P1 of the upper limit of the lower beam and the height position P2 of the lower limit of the lower beam (see Figure 4).

[0013] The lower beam encoder 105 is primarily used to detect the rotation of the lower beam motor 101 and generate a lower beam encoder signal. Furthermore, the lower beam encoder 105 includes a lower beam magnetic wheel 1051 and a lower beam magnetic sensor 1052. The lower beam magnetic wheel 1051 is connected to the lower beam motor 101, and when the lower beam drive shaft 104 is driven by the lower beam motor 101 and rotates, the lower beam magnetic wheel 1051 also rotates in conjunction. The lower beam magnetic sensor 1052 is fixed to a position close to the periphery of the lower beam magnetic wheel 1051 on the lower beam motor 101 and is electrically connected to the control device 106. The lower beam magnetic sensor 1052 can detect magnetic changes through the rotation of the lower beam magnetic wheel 1051, and thus detects the rotation of the lower beam motor 101 and generates a lower beam encoder signal representing the current position of the lower beam. Examples of the lower beam magnetic sensor 1052 include, but are not limited to, a Hall sensor. Furthermore, other types of lower beam encoders 105 can also be used, such as optical encoders that optically detect the motion state.

[0014] Continuing to refer to Figure 3, Figure 3 is a functional block diagram of a first motorized shielding device according to an embodiment of the present invention. The control device 106 of the first motorized shielding device 1 comprises a motor drive module 1062, a microprocessor 1061, an encoder signal detection module 1063, and a memory 1065. The microprocessor 1061 is electrically connected to the motor drive module 1062, the encoder signal detection module 1063, the control command transmission / reception module 108, and the memory 1065. The motor drive module 1062 is electrically connected to the lower beam motor 101, and the microprocessor 1061 transmits drive signals to the motor drive module 1062, enabling the motor drive module 1062 to control the rotation or stopping of the lower beam motor 101 based on the drive signals. The control command transmission / reception module 108 is electrically connected to a power supply unit 103 for supplying power to the control command transmission / reception module 108.

[0015] The encoder signal detection module 1063 is electrically connected to the lower beam encoder 105 and is used to check the integrity of the lower beam encoder signal. The microprocessor 1061 receives the lower beam encoder signal from the encoder signal detection module 1063 to obtain the current position of the lower beam when the lower beam 12 of the first motorized shielding device 1 is stopped or stationary. The memory 1065 functions as an external cache space for data for the microprocessor 1061. The first motorized shielding device 1 may further include a remote control device 107. The control command transmission / reception module 108 is communicably connected to the remote control device 107, but in this embodiment, the remote control device 107 may be a user-operable remote wireless control device that generates and transmits wireless remote control commands to the control command transmission / reception module 108, which then transmits the wireless remote control commands to the microprocessor 1061. In another embodiment, the remote control device 107 may be a centralized console that generates remote control commands based on user settings or input from environmental sensors (e.g., an ambient light sensor) and transmits them to a control command transmission / reception module 108 via wired or wireless means, which then transmits the remote control commands to a microprocessor 1061. In this embodiment, the microprocessor 1061 functions as the core of the control device 106 for executing control commands such as aligning, moving, and stopping the lower beam 12.

[0016] The shielding material 11 varies depending on the type of the first electric shielding device. In this embodiment, the first electric shielding device 1 is an electric honeycomb screen, and the shielding material 11 may be a plurality of hollow curtain sheets (not shown) provided between the upper beam 10 and the lower beam 12, having a hexagonal side cross-section and connected in series. In other embodiments, the first electric shielding device 1 may be an electric blind, and the shielding material 11 may be a plurality of louvers provided between the upper beam 10 and the lower beam 12, parallel to the upper beam 10 and the lower beam 12 and parallel to each other. In this embodiment, the lower beam drive assembly, power supply unit 103 and control device 106 are provided in the internal space of the upper beam 10, but in other embodiments, at least a portion of the lower beam drive assembly, power supply unit 103 and control device 106 may be provided in the internal space of the lower beam 12, or they may be provided outside the upper beam 10 and the lower beam 12 but in a location close to the shielding material 11.

[0017] The control device 106 is used to release or rewind the lower beam cord 13 by controlling the lower beam motor 101 to rotate the lower beam winding shaft 102, thereby lowering or raising the lower beam 12 and deploying or folding the shielding material 11, and can also acquire the current position of the lower beam based on the lower beam encoder signal of the lower beam magnetic sensor 1052. In particular, when the lower beam 12 has stopped moving or is stationary after completing its movement, the control device 106 acquires the current position of the lower beam based on the lower beam encoder signal. When the control device 106 receives a specific remote control command via the control command transmission / reception module 108, the control device 106 transmits a first alignment packet to a second motorized shielding device of the same group, receives a second alignment packet from the second motorized shielding device, and controls the lower beam motor 101 to align the lower beam 12 based on the first and second alignment packets. Of these, the first alignment packet contains information about the current position of the lower beam 12 of the first motorized shielding device 1 when it is stopped or stationary, and the second alignment packet contains information about the current position of the lower beam of the second motorized shielding device when it is stopped or stationary. Incidentally, since the first motorized shielding device and the second motorized shielding device are motorized shielding devices with the same structure, a redundant explanation of the structure of the second motorized shielding device will be omitted here.

[0018] In the above-described embodiment, the example of the motorized shading devices with two frame structures and the same vertical height and belonging to the same group was described. However, in other embodiments, the motorized shading device system may have motorized shading devices with three or more frame structures and the same vertical height and belonging to the same group. In this embodiment, the control device 106 of the first motorized shading device 1 transmits the first alignment packet to the second to Nth motorized shading devices within the same group, and receives the second to Nth alignment packets transmitted from the control devices of the second to Nth motorized shading devices respectively. Further, the control device 106 of the first motorized shading device 1 controls the lower beam motor 101 to align the lower beam 12 based on the first to Nth alignment packets. Among them, the first alignment packet includes information on the current position of the lower beam when the lower beam 12 of the first motorized shading device 1 is stopped or stationary. The second to Nth alignment packets each include information on the current position of the lower beam when the lower beam of the second to Nth motorized shading devices is stopped or stationary, where N is an integer of 3 or more.

[0019] Referring to Figure 4, Figure 4 is a schematic diagram showing a state in which the lower beams of the first and second electric shielding devices of a shielding device system according to one embodiment of the present invention are not aligned. The shielding device system comprises at least two first electric shielding devices 1A and second electric shielding devices 1B belonging to the same group. The first electric shielding device 1A and the second electric shielding device 1B are respectively positioned in windows W1 and W2 having the same height dimension on the vertical axis and are connected to each other in a communicative manner, and each of the first electric shielding device 1A and the second electric shielding device 1B comprises the plurality of components of the first electric shielding device 1 shown in Figures 1 to 3. In this embodiment, the upper beams 10A and 10B of the first electric shielding device 1A and the second electric shielding device 1B are provided at a position Y1 on the vertical axis, that is, the first electric shielding device 1A and the second electric shielding device 1B are mounted at a fixed position Y1, and the first electric shielding device 1A and the second electric shielding device 1B are provided at the same height on windows W1 and W2. Therefore, the height position P1 of the upper limit of the lower beam and the height position P2 of the lower limit of the lower beam in the movement section of the lower beams 12A and 12B provided by the first electric shielding device 1A and the second electric shielding device 1B are at the same height.

[0020] When the control devices of the first electric shielding device 1A and the second electric shielding device 1B receive a remote control command to move the lower beams 12A, 12B downward, the control devices of the first electric shielding device 1A and the second electric shielding device 1B can control their respective lower beam motors to move their respective lower beams 12A, 12B downward with respect to the upper beams 10A, 10B. And when the control devices of the first electric shielding device 1A and the second electric shielding device 1B receive a specific remote control command, for example, a stop command, they control the lower beam motors to stop the movement of the lower beams 12A, 12B. Since there may be a time difference due to environmental factors when the control devices of the first electric shielding device 1A and the second electric shielding device 1B receive a movement command and / or a stop command, the lower beams 12A, 12B of the first electric shielding device 1A and the second electric shielding device 1B do not start or stop moving simultaneously. When the lower beams 12A, 12B of the first electric shielding device 1A and the second electric shielding device 1B stop moving, the lower beams 12A, 12B will stop at the heights of positions Y3 and Y2 respectively.

[0021] Through the lower beam encoder signal generated by the lower beam encoder of the first electric shielding device 1A, which represents the current position of the lower beam when the lower beam 12A of the first electric shielding device 1A is stopped or stationary, the first electric shielding device 1A can determine that the current position of its lower beam is position Y3, and through the lower beam encoder signal generated by the lower beam encoder of the second electric shielding device 1B, which represents the current position of the lower beam when the lower beam 12B of the second electric shielding device 1B is stopped or stationary, the control device of the second electric shielding device 1B can determine that the current position of its lower beam is position Y2. However, the first electric shielding device 1A still does not know the current position of the lower beam of the second electric shielding device 1B at that time, and similarly, the second electric shielding device 1B does not know the current position of the lower beam of the first electric shielding device 1A. However, as shown in Figure 4, the lower beams 12A and 12B of the first motorized shielding device 1A and the second motorized shielding device 1B are not aligned as expected by the user. Therefore, the control devices of the first motorized shielding device 1A and the second motorized shielding device 1B perform an automatic alignment method based on transmission packets. The control device of the first motorized shielding device 1A generates a first alignment packet and transmits it to the second motorized shielding device 1B, and the control device of the second motorized shielding device 1B generates a second alignment packet and transmits it to the first motorized shielding device 1A. The first alignment packet contains information about the current position of the lower beam 12A of the first motorized shielding device 1A when it is stopped or stationary, and the second alignment packet contains information about the current position of the lower beam 12B of the second motorized shielding device 1B when it is stopped or stationary. The control devices for the first motorized shielding device 1A and the second motorized shielding device 1B can determine that the current positions of the lower beams are Y3 and Y2, respectively, based on the first alignment packet and the second alignment packet, and perform automatic alignment of the lower beams 12A and 12B based on this.In this embodiment, the lower beam 12B of the second electric shielding device 1B is held at position Y2, and the lower beam 12A of the first electric shielding device 1A moves upward to position Y2, or the lower beam 12A of the first electric shielding device 1A is held at position Y3, and the lower beam 12B of the second electric shielding device 1B moves downward to position Y3. Preferably, the control devices of the first motorized shielding device 1A and the second motorized shielding device 1B further control their lower beam motors based on the first alignment packet, the second alignment packet, and the preceding movement direction of their lower beams 12A and 12B to align the lower beams 12A and 12B. As a result, the lower beam 12A of the first motorized shielding device 1A is kept at position Y3, and the lower beam 12B of the second motorized shielding device 1B moves downward to position Y3, thereby stopping both the lower beam 12A of the first motorized shielding device 1A and the lower beam 12B of the second motorized shielding device 1B at position Y3 and achieving the effect of aligning the lower beams 12A and 12B.

[0022] In the above embodiment, the case where the height position P1 of the upper limit position of the lower beam of the first electric shielding device 1A and the second electric shielding device 1B is set to the first upper limit initial position was described as an example. However, the distance between the current position of the lower beam and the first upper limit initial position is the travel distance of the lower beam, and if the travel distance of the lower beams of the first electric shielding device 1A and the second electric shielding device 1B is the same, the lower beams 12A and 12B will be located at the same height position. Therefore, the height of the height position P2 of the lower limit position of the lower beam of the first electric shielding device 1A and the second electric shielding device 1B may be the same or different, that is, the height dimensions of the windows W1 and W2 on the vertical axis may be the same or different. Furthermore, in some cases, it may not be possible to align the height position P1 of the upper limit of the lower beam of the first electric shielding device 1A and the second electric shielding device 1B. However, it is possible to align the height position P2 of the lower limit of the lower beam of the first electric shielding device 1A and the second electric shielding device 1B. In this case, the height position P2 of the lower limit of the lower beam of the first electric shielding device 1A and the second electric shielding device 1B is set to the first initial lower limit position. The distance between the current position of the lower beam and the first initial lower limit position becomes the movement distance of the lower beam. If the movement distance of the lower beams of the first electric shielding device 1A and the second electric shielding device 1B is the same, the lower beams 12A and 12B will be located at the same height position. Therefore, the height of the height position P1 of the upper limit of the lower beam of the first electric shielding device 1A and the second electric shielding device 1B may be the same or different, meaning that the height dimensions of the windows W1 and W2 on the vertical axis may be the same or different.

[0023] Furthermore, although the above-described embodiment illustrates an example in which the lower beams 12A and 12B are aligned after receiving a specific remote control command signifying a stop command, the present invention is not limited to these. In one embodiment, the control devices of the first electric shielding device 1A and the second electric shielding device 1B receive, for example, a specific remote control command to move the lower beams 12A and 12B to a predetermined position, and after the lower beams 12A and 12B have moved to the predetermined position and stopped, the control devices of the first electric shielding device 1A and the second electric shielding device 1B may automatically execute the automatic alignment method based on the transmission packet. In one embodiment, the lower beams 12A and 12B of the first electric shielding device 1A and the second electric shielding device 1B remain stationary for a certain period of time, and the control devices of the first electric shielding device 1A and the second electric shielding device 1B may execute the automatic alignment method based on the transmission packet after receiving a specific remote control command signifying active alignment.

[0024] Furthermore, each of the first and second alignment packets may contain information such as the type of shielding device and group code. Only the first motorized shielding device 1A and the second motorized shielding device 1B of the same type and group perform alignment of the lower beams 12A and 12B. In other words, the control devices of the first motorized shielding device 1A and the second motorized shielding device 1B perform comparisons and decisions to discard alignment packets of different types or groups of shielding devices, and the discarded alignment packets are not used as the basis for controlling the alignment of the lower beams 12A and 12B. In addition, the first alignment packet may further include information regarding the maximum lower beam travel distance between the height position P1 of the upper limit position of the lower beam and the height position P2 of the lower limit position of the lower beam of the first motorized shielding device 1A, and a predetermined maximum lower beam alignment distance, wherein the maximum lower beam travel distance is the maximum distance that the lower beam 12A of the first motorized shielding device 1A can move (i.e., the distance between the height position P1 of the upper limit position of the lower beam and the height position P2 of the lower limit position of the lower beam of the first motorized shielding device 1A), and the maximum lower beam alignment distance is the maximum distance that the lower beam 12A of the first motorized shielding device 1A can move when aligning, and the maximum lower beam alignment distance may be a predetermined distance or may depend on a ratio of the maximum lower beam travel distance. The second alignment packet may further include information regarding the maximum lower beam travel distance between the height position P1 of the upper limit position of the lower beam and the height position P2 of the lower limit position of the lower beam of the second motorized shielding device 1B, and a predetermined maximum lower beam alignment distance, wherein the maximum lower beam travel distance is the maximum distance that the lower beam 12B of the second motorized shielding device 1B can move (i.e., the distance between the height position P1 of the upper limit position of the lower beam and the height position P2 of the lower limit position of the lower beam of the second motorized shielding device 1B), and the maximum lower beam alignment distance is the maximum distance that the lower beam 12B of the second motorized shielding device 1B can move when aligning, and the maximum lower beam alignment distance may be a predetermined distance or may depend on a ratio of the maximum lower beam travel distance.The maximum lower beam travel distances of the first motorized shielding device 1A and the second motorized shielding device 1B may be the same or different, and similarly, the maximum lower beam alignment distances may be the same or different.

[0025] The motorized shielding system comprises three motorized shielding devices. If the control device of the first motorized shielding device 1A determines that the difference between the maximum lower beam travel distance of the first motorized shielding device 1A and the maximum lower beam travel distance in the received second alignment packet is greater than a predetermined threshold, the control device of the first motorized shielding device 1A discards the second alignment packet. The discarded alignment packet is not used as the basis for controlling the alignment of the lower beam 12A; that is, the alignment of the lower beam 12A is performed using the first alignment packet and the third alignment packet provided by the third motorized shielding device. Similarly, if the control device of the second motorized shielding device 1B determines that the difference between its maximum lower beam travel distance and the maximum lower beam travel distance in the received first alignment packet is greater than a predetermined threshold, the control device of the second motorized shielding device 1B discards the first alignment packet, and the discarded alignment packet is not used as a basis for controlling the alignment of the lower beam 12B. Instead, the lower beam 12B is aligned using the second alignment packet and the third alignment packet provided by the third motorized shielding device.

[0026] In other embodiments, the first and second electric shielding devices 1A and 1B, which are of the same type, belong to the same group, and have the same maximum lower beam travel distance, can be designed to align the lower beams 12A and 12B. Furthermore, if the travel distance required for the lower beam 12A of the first electric shielding device 1A to move to the lower beam alignment position is greater than the maximum lower beam alignment distance of the first electric shielding device 1A, the control device of the first electric shielding device 1A will not align the lower beam 12A.

[0027] Continuing to refer to Figures 5(a) and 5(b), Figures 5(a) and 5(b) are schematic diagrams illustrating a minimum scale-based alignment method for a first motorized shielding device according to one embodiment of the present invention. To make the alignment of the lower beam 12A more precise, the control device can perform a minimum scale-based alignment method in addition to performing an automatic alignment method based on transmission packets. In Figure 5(a), when the first motorized shielding device 1A receives a specific remote control command to move the lower beam 12A downward at position Y4, the control device of the first motorized shielding device 1A moves the lower beam 12A of the first motorized shielding device 1A to a predetermined target position, for example, position Y5, which corresponds to an integer multiple of the minimum scale based on the distance the lower beam 12A should move, at position Y5, which is an integer multiple of the minimum scale. The minimum scale may be, for example, one distance that corresponds to 10 rotations of the lower beam motor, but the present invention is not limited thereto.

[0028] Unlike Figure 5(a), in Figure 5(b), after the first motorized shielding device 1A receives a remote control command signifying movement without positional restrictions, the user observes the movement of the lower beam 12A, and when the user observes that the lower beam 12A has moved to a position specified by the user, for example, position Y5, the first motorized shielding device 1A receives a specific remote control command signifying a stop command. If the minimum scale-based alignment method is not used, the control device plans the target position as position Y6 based on the current speed and reduction mechanism of the lower beam motor, but position Y6 is not an integer multiple of the minimum scale. After using the minimum scale-based alignment method, the control device corrects the target position to position Y7, of which position Y7 is an integer multiple of the minimum scale. In short, when the minimum scale-based alignment method is adopted, the position where the lower beam 12 will ultimately stop is only an integer multiple of the minimum scale.

[0029] Continuing to refer to Figure 6, Figure 6 is a schematic diagram showing a state in which a first motorized shielding device and a second motorized shielding device according to one embodiment of the present invention use an automatic alignment method based on transmission packets. Because an alignment method based on small scale divisions is used, the control devices of the first motorized shielding device 1A and the second motorized shielding device 1B sequentially receive two remote control commands, a move command and a stop command, and then stop the lower beams 12A and 12B of the first motorized shielding device 1A and the second motorized shielding device 1B at positions Y2 and Y3, respectively, where positions Y2 and Y3 are integer multiples of the smallest scale division. Next, the control devices of the first motorized shielding device 1A and the second motorized shielding device 1B execute the automatic alignment method based on the transmission packets described above. The control device of the first motorized shielding device 1A controls the lower beam motor to move its lower beam 12A downward to position Y3 based on the received second alignment packet and its own first alignment packet, while the control device of the second motorized shielding device 1B does not move its lower beam 12B based on the received first alignment packet and its own second alignment packet. In short, after the automatic alignment, the lower beams 12A and 12B of the first motorized shielding device 1A and the second motorized shielding device 1B are positioned at one lower beam alignment position, and the lower beam alignment position is an integer multiple of the smallest scale division.

[0030] Continuing to refer to Figures 7 and 8, Figure 7 is a schematic diagram showing a first motorized shielding device according to another embodiment of the present invention, and Figure 8 is a schematic diagram showing a magnified view of a lower beam motor, intermediate beam motor, and control device of the first motorized shielding device according to another embodiment of the present invention. Unlike the first motorized shielding device 1 in Figures 1 and 2, in this embodiment, the first motorized shielding device 1' further comprises an intermediate beam 14 positioned between the upper beam 10 and the lower beam 12, and the internal space of the upper beam 10 further comprises an intermediate beam motor 101', an intermediate beam winding shaft 102', and an intermediate beam encoder 105', the intermediate beam encoder 105' is capable of detecting the rotation of the intermediate beam motor 101' and generating an intermediate beam encoder signal, the intermediate beam encoder 105' being composed of an intermediate beam magnetic wheel 1051' connected to the intermediate beam motor 101', and an intermediate beam magnetic sensor 1052' fixed to the intermediate beam motor 101' and close to the periphery of the intermediate beam magnetic wheel 1051'. Furthermore, the intermediate beam motor 101', the intermediate beam winding shaft 102', and the intermediate beam encoder 105' constitute an intermediate beam drive assembly, and can move the intermediate beam 14 between the upper intermediate beam position and the lower intermediate beam position relative to the upper beam 10.

[0031] The power supply unit 103 supplies DC power to the intermediate beam motor 101' and the intermediate beam encoder 105' by being electrically connected to them. The control device 106 controls the rotation of the intermediate beam motor 101' and the intermediate beam encoder 105' by being electrically connected to them, and also receives the intermediate beam encoder signal generated by the intermediate beam encoder 105'. The intermediate beam motor 101' is connected to two intermediate beam winding shafts 102' via an intermediate beam drive shaft 104', so that the two intermediate beam winding shafts 102' rotate in synchronization with the rotation of the intermediate beam motor 101'. Two intermediate beam winding shafts 102' are each connected to the intermediate beam 14 via two intermediate beam cords 13', one end of which is connected to the intermediate beam winding shaft 102' and the other end of which is fixed to the intermediate beam 14. The control device 106 controls the rotation of the intermediate beam motor 101', causing the intermediate beam winding shaft 102' to wind up or unwind the intermediate beam cords 13', thereby moving the intermediate beam 14 between the upper intermediate beam position and the lower intermediate beam position relative to the upper beam 10. Since the intermediate beam encoder 105' can detect the rotation of the intermediate beam motor 101', when the control device 106 controls the intermediate beam motor 101' to stop it, the intermediate beam encoder 105' generates an intermediate beam encoder signal representing the current position of the intermediate beam when the intermediate beam 14 of the first motorized shielding device 1' is stopped or stationary. In this embodiment, the shielding material 11 is connected between the intermediate beam 14 and the lower beam 12, but one shielding material may also be connected between the intermediate beam 14 and the lower beam 12, and between the upper beam 10 and the intermediate beam 14 (not shown).

[0032] In this embodiment, the intermediate beam drive assembly is provided in the internal space of the upper beam 10. However, in other embodiments, part or all of the intermediate beam drive assembly may be provided in the internal space of the lower beam 12 or the intermediate beam 14, or it may be provided outside the upper beam 10, lower beam 12, and intermediate beam 14 in a location close to the shielding material 11.

[0033] After the intermediate beam 14 and lower beam 12 of the first motorized shielding device 1' move and stop (for example, when the control device 106 receives a movement command and a stop command in sequence, or when it receives a predetermined position command that causes the intermediate beam 14 and lower beam 12 to directly reach a predetermined position), or after the intermediate beam 14 and lower beam 12 of the first motorized shielding device 1' remain stationary for a certain period of time and the control device 106 receives a specific remote control command signifying active alignment, the control device 106 executes an automatic alignment method based on transmission packets, wherein the first alignment packet further includes information regarding the current position of the lower beam when the lower beam 12 of the first motorized shielding device 1' is stopped or stationary, as well as information regarding the current position of the intermediate beam 14 of the first motorized shielding device 1' when it is stopped or stationary, and the second alignment packet further includes information regarding the current position of the lower beam when the lower beam of the second motorized shielding device is stopped or stationary, as well as information regarding the current position of the intermediate beam when the intermediate beam of the second motorized shielding device is stopped or stationary. Therefore, the first motorized shielding device 1' can align its lower beam 12 and intermediate beam 14 by controlling its lower beam motor 101 and intermediate beam motor 101' based on the second alignment packet it receives and its own first alignment packet, and similarly, the second motorized shielding device can align its lower beam and intermediate beam by controlling its lower beam motor and intermediate beam motor based on the first alignment packet it receives and its own second alignment packet.

[0034] To elaborate, in one case, the upper limit position of the lower beam of the first electric shielding device 1' and the upper limit position of the lower beam of the second electric shielding device are aligned with the first upper limit initial position, and the distance between the current position of the lower beam and the first upper limit initial position becomes the travel distance of the lower beam. Similarly, the upper limit position of the intermediate beam of the first electric shielding device 1' and the upper limit position of the intermediate beam of the second electric shielding device are aligned with the second upper limit initial position, and the distance between the current position of the intermediate beam and the second upper limit initial position becomes the travel distance of the intermediate beam. In other cases, the lower limit position of the lower beam of the first electric shielding device 1' and the lower limit position of the lower beam of the second electric shielding device are aligned with the first initial lower limit position, and the distance between the current position of the lower beam and the first initial lower limit position is the travel distance of the lower beam, and the intermediate beam lower limit position of the first electric shielding device 1' and the intermediate beam lower limit position of the second electric shielding device are aligned with the second initial lower limit position, and the distance between the current position of the intermediate beam and the second initial lower limit position is the travel distance of the intermediate beam.

[0035] In addition, when using a combination of alignment methods based on the minimum scale, the distance from the alignment position of the intermediate beam 14 to the second upper initial position or the second lower initial position becomes an integer multiple of the minimum scale, and the distance from the alignment position of the lower beam 12 to the first upper initial position or the first lower initial position also becomes an integer multiple of the minimum scale. That is, after automatic alignment, the lower beam 12 is located at the lower beam alignment position, the intermediate beam 14 is located at the intermediate beam alignment position, and both the lower beam alignment position and the intermediate beam alignment position are integer multiples of the minimum scale. Furthermore, in addition to relying on the first and second alignment packets described above, the control device 106 can also perform alignment of the intermediate beam 14 by taking into account the preceding direction of movement of the intermediate beam 14. On the other hand, the first alignment packet further includes information regarding the maximum lower beam travel distance between the upper and lower lower beam limits of the first motorized shielding device 1', a predetermined maximum lower beam alignment distance (i.e., the maximum distance the lower beam can move from its current position to the lower beam alignment position), the maximum intermediate beam travel distance between the upper and lower intermediate beam limits, and a predetermined maximum intermediate beam alignment distance (i.e., the maximum distance the intermediate beam can move from its current position to the intermediate beam alignment position). The second alignment packet further includes information regarding the maximum lower beam travel distance between the upper and lower lower beam limits of the second motorized shielding device, a predetermined maximum lower beam alignment distance (i.e., the maximum distance the lower beam can move from its current position to the lower beam alignment position), the maximum intermediate beam travel distance between the upper and lower intermediate beam limits, and a predetermined maximum intermediate beam alignment distance (i.e., the maximum distance the intermediate beam can move from its current position to the intermediate beam alignment position).If the electric shielding system has three or more electric shielding devices, when performing automatic alignment of the intermediate beam 14 and the lower beam 12, the control device 106 can decide whether to discard the second alignment packet based on the information of the second alignment packet, as described above, and without using the discarded second alignment packet as the basis for aligning the intermediate beam 14 and the lower beam 12, for example, if there is a third electric shielding device in the electric shielding system, the control device 106 of the first electric shielding device 1' will discard the second alignment packet of the second electric shielding device after the decision, and align the intermediate beam 14 and the lower beam 12 based on the first alignment packet of the first electric shielding device 1' and the third alignment packet of the third electric shielding device.

[0036] Referring to Figure 9, Figure 9 is a schematic diagram showing a state in which the intermediate beam and the lower beam of the first and second electric shielding devices of a shielding device system according to one embodiment of the present invention are not aligned. In this embodiment, the upper beams 10A and 10B of the first electric shielding device 1A' and the second electric shielding device 1B' are positioned at position Y1 on the vertical axis and aligned to position Y1, the lower beams 12A and 12B are both movable between a height position P1 of the upper limit of the lower beam and a height position P2 of the lower limit of the lower beam, and the intermediate beams 14A and 14B are both movable between an upper limit of the intermediate beam and a lower limit of the intermediate beam. If the control commands received by the control devices of the first electric shielding device 1A' and the second electric shielding device 1B' are, for example, commands to move both the intermediate beams 14A, 14B and the lower beams 12A, 12B downward, the control devices of the first electric shielding device 1A' and the second electric shielding device 1B' will control their respective lower beam motors and intermediate beam motors to move the lower beams 12A, 12B and the intermediate beams 14A, 14B downward, and then the control devices of the first electric shielding device 1A' and the second electric shielding device 1B' will... When it receives a specific remote control command that signifies a stop command, it controls its lower beam motor and intermediate beam motor, respectively, to stop the lower beams 12A, 12B and intermediate beams 14A, 14B. At this time, because there is a time difference in receiving the signal, the lower beams 12A, 12B of the first electric shielding device 1A' and the second electric shielding device 1B' stop at positions Y4 and Y5, respectively, and the intermediate beams 14A, 14B of the first electric shielding device 1A' and the second electric shielding device 1B' stop at positions Y2 and Y3, respectively.

[0037] Through the lower beam encoder signal and the intermediate beam encoder signal of the first electric shielding device 1A', the control device of the first electric shielding device 1A' determines that the current position of the lower beam 12A when it is stopped or stationary is position Y4, and that the current position of the intermediate beam 14A when it is stopped or stationary is position Y2. Through the lower beam encoder signal and the intermediate beam encoder signal of the second electric shielding device 1B', the control device of the second electric shielding device 1B' determines that the current position of the lower beam 12B when it is stopped or stationary is position Y5, and that the current position of the intermediate beam 14B when it is stopped or stationary is position Y3. However, as can be clearly seen from Figure 9, the lower beams 12A and 12B of the first electric shielding device 1A' and the second electric shielding device 1B' are not aligned, and the intermediate beams 14A and 14B of the first electric shielding device 1A' and the second electric shielding device 1B' are also not aligned. As a result, the shading positions of the adjacent first electric shielding device 1A' and the second electric shielding device 1B' are misaligned, causing confusion and affecting the visual aesthetics in a way that does not meet user expectations. In this case, the control devices for the first electric shielding device 1A' and the second electric shielding device 1B' according to one embodiment of the present invention execute an automatic alignment method based on transmission packets. The control device for the first electric shielding device 1A' generates a first alignment packet and transmits it to the second electric shielding device 1B', and the control device for the second electric shielding device 1B' generates a second alignment packet and transmits it to the first electric shielding device 1A'. The first alignment packet contains information regarding the current positions of the lower beam and the intermediate beam of the first motorized shielding device 1A', and the second alignment packet contains information regarding the current positions of the lower beam and the intermediate beam of the second motorized shielding device 1B'. The control devices of the first motorized shielding device 1A' and the second motorized shielding device 1B' perform automatic alignment of the lower beams 12A, 12B and the intermediate beams 14A, 14B based on the first and second alignment packets.In this embodiment, the lower beam 12A of the first electric shielding device 1A' moves downward to position Y5, or the lower beam 12B of the second electric shielding device 1B' moves upward to position Y4, and the intermediate beam 14A of the first electric shielding device 1A' moves downward to position Y3, or the intermediate beam 14B of the second electric shielding device 1B' moves upward to position Y2. Preferably, depending on the preceding movement direction of the intermediate beams 14A, 14B and the lower beams 12A, 12B, the lower beam 12A of the first electric shielding device 1A' moves downward to position Y5, and the intermediate beam 14A of the first electric shielding device 1A' moves downward to position Y3.

[0038] Based on the above, the present invention further provides a shielding device alignment method. Referring to Figure 10, Figure 10 is a flowchart showing a shielding device alignment method according to one embodiment of the present invention. The shielding device alignment method MS is used in an electric shielding device system comprising a first electric shielding device and a second electric shielding device, and comprises the following steps S1 to S4. In step S1, after the control device of the first electric shielding device receives a specific remote control command, the first electric shielding device transmits a first alignment packet to the second electric shielding device, the first alignment packet of which includes information regarding the current position of the lower beam when the lower beam of the first electric shielding device is stopped or stationary. In step S2, after the control device of the second electric shielding device receives a specific remote control command, the second electric shielding device transmits a second alignment packet to the first electric shielding device, the second alignment packet of which includes information regarding the current position of the lower beam when the lower beam of the second electric shielding device is stopped or stationary. In step S3, the control device of the first motorized shielding device aligns the lower beam of the first motorized shielding device by controlling the lower beam motor of the first motorized shielding device based on a first alignment packet and a second alignment packet. Similarly, in step S4, the control device of the second motorized shielding device aligns the lower beam of the second motorized shielding device by controlling the lower beam motor of the second motorized shielding device based on a first alignment packet and a second alignment packet. Specific remote control commands include a stop command, an active alignment command, or a predetermined position command. The order of steps S1 and S2 is not intended to limit the present invention; that is, step S2 may be performed before step S1 or simultaneously with step S1. Similarly, the order of steps S3 and S4 is not intended to limit the present invention; that is, step S4 may be performed before step S3 or simultaneously with step S3.

[0039] In the above method, the first alignment packet further includes information regarding the current position of the intermediate beam of the first motorized shielding device when the intermediate beam is stopped or stationary, and the second alignment packet further includes information regarding the current position of the intermediate beam of the second motorized shielding device when the intermediate beam is stopped or stationary. In steps S3 and S4, the control devices for the first motorized shielding device and the second motorized shielding device each independently control the lower beam motor of the first motorized shielding device and the lower beam motor of the second motorized shielding device based on the first alignment packet and the second alignment packet, respectively, thereby aligning the lower beam of the first motorized shielding device and the lower beam of the second motorized shielding device. Furthermore, the control devices for the first and second motorized shielding devices independently control the intermediate beam motors of the first and second motorized shielding devices, respectively, based on the first and second alignment packets, thereby aligning the intermediate beams of the first and second motorized shielding devices.

[0040] In the above method, the upper limit position of the lower beam of the first electric shielding device and the upper limit position of the lower beam of the second electric shielding device are aligned and positioned at the first upper limit initial position, the distance between the current position of the lower beam of the first electric shielding device and the first upper limit initial position is the travel distance of the lower beam of the first electric shielding device, the distance between the current position of the lower beam of the second electric shielding device and the first upper limit initial position is the travel distance of the lower beam of the second electric shielding device, and the upper limit position of the intermediate beam of the first electric shielding device and the upper limit position of the intermediate beam of the second electric shielding device are aligned and positioned at the second upper limit initial position, the distance between the current position of the intermediate beam of the first electric shielding device and the second upper limit initial position is the travel distance of the intermediate beam of the first electric shielding device, and the distance between the current position of the intermediate beam of the second electric shielding device and the second upper limit initial position is the travel distance of the intermediate beam of the second electric shielding device. Alternatively, the lower limit position of the lower beam of the first electric shielding device and the lower limit position of the lower beam of the second electric shielding device are aligned to the first lower limit initial position, and the distance between the current position of the lower beam of the first electric shielding device and the first lower limit initial position becomes the travel distance of the lower beam of the first electric shielding device, and the distance between the current position of the lower beam of the second electric shielding device and the first lower limit initial position becomes the travel distance of the lower beam of the second electric shielding device, and the lower limit position of the intermediate beam of the first electric shielding device and the lower limit position of the intermediate beam of the second electric shielding device are aligned to the second lower limit initial position, and the distance between the current position of the intermediate beam of the first electric shielding device and the second lower limit initial position becomes the travel distance of the intermediate beam of the first electric shielding device, and the distance between the current position of the intermediate beam of the second electric shielding device and the second lower limit initial position becomes the travel distance of the intermediate beam of the second electric shielding device.

[0041] In the above method, the lower beam of the first electric shielding device and the lower beam of the second electric shielding device are aligned to the lower beam alignment position, and the intermediate beam of the first electric shielding device and the intermediate beam of the second electric shielding device are aligned to the intermediate beam alignment position, with each of the lower beam alignment position and the intermediate beam alignment position being an integer multiple of the smallest scale division.

[0042] In the above method, the first alignment packet further includes information regarding the maximum lower beam travel distance between the lower beam upper limit position and the lower beam lower limit position of the first motorized shielding device, a predetermined maximum lower beam alignment distance of the first motorized shielding device, the maximum intermediate beam travel distance between the intermediate beam upper limit position and the intermediate beam lower limit position of the first motorized shielding device, and a predetermined maximum intermediate beam alignment distance of the first motorized shielding device; the second alignment packet further includes information regarding the maximum lower beam travel distance between the lower beam upper limit position and the lower beam lower limit position of the second motorized shielding device, a predetermined maximum lower beam alignment distance of the second motorized shielding device, the maximum intermediate beam travel distance between the intermediate beam upper limit position and the intermediate beam lower limit position of the second motorized shielding device, and a predetermined maximum intermediate beam alignment distance of the second motorized shielding device.

[0043] In summary, the electric shielding device, electric shielding device system, and shielding device alignment method provided by the present invention have at least the following features: 1) By using an automatic alignment method based on transmission packets, each electric shielding device can be aligned independently without the need for additional centralized console management; 2) The elimination of the need for additional centralized console management reduces costs and power consumption, increases market competitiveness, and aligns with the trends of energy conservation and carbon reduction; 3) Alignment accuracy is further improved by the ability to combine it with an alignment method based on the minimum scale; and 4) The shielding device alignment method is applicable to various shielding devices, such as the honeycomb shielding device and blinds mentioned above, and can also be applied to roll shielding devices. In other words, the electric shielding device may be an electric honeycomb shielding device, an electric blind, or an electric roll shielding device. Simply put, the shielding device alignment method is versatile.
