Description

Blind automatic control system {blind automatic control system}

The present invention relates to an automatic control system for blinds, and more specifically, basic control and scheduled operation control can be driven using a cloud server, and in particular, the angle and direction of the slats as well as vertical movement height alignment of multiple Venetian blinds. This relates to an automatic blind control system that controls the operation of blinds so that they can be aligned consistently.

Blinds are used to block light or protect privacy. These blinds are installed on windows or verandas in offices, living rooms, bedrooms, studies, master bedrooms, kitchens, and children's rooms to block sunlight while allowing a certain degree of ventilation, preventing indoor furniture, home appliances, and carpets from fading in sunlight. It has the function of blocking airflow, blocking the outside world to some extent, and decorating the atmosphere of the room.

These general blinds were developed so that the height of the blind can be adjusted by driving an electric motor installed inside by human hands or a separate remote control, but recently, ICT (Information and Communications Technologies) technology and IoT have been applied to blinds. By converging (Internet of Things) technologies, blinds that combine ICT and IoT technologies that can be automatically controlled indoors and outdoors in real time are being actively developed.

Conventional technology is a multi-blind device that can easily open and close the blind, and can control the opening and closing of the blind. However, it only provides a general automatic opening and closing device through blind winding, and provides feedback that can accurately control the height of the blind. There was a problem that the system could not provide.

In addition, in the case of Venetian blinds, there was a fundamental problem that it was very difficult to uniformly align the slat angle and the opening height of the blind due to errors due to the measured position of the blind and the alignment of the slats.

Therefore, there is a need to develop a blind alignment system that can simultaneously align the heights of multiple blinds and the angles of the slats.

Hereinafter, an embodiment of the automatic blind control system of the present invention will be described in detail with reference to the drawings.

Referring to Figures 1 and 2, the present invention includes a blind unit 100, a position identification unit 200, a position setting unit 300, and an operation control unit 400.

The blind unit 100 includes at least two independently driven blinds 110 to form one group. The blind 110 is sequentially stacked on the lower bar 111 and the upper side of the lower bar 111, and includes a plurality of slats 112 that open and close the opening and rotation that controls the angles of the lower bar 111 and the slats 112. Includes motor 113.

The blind 110 has a lower bar 111 raised and lowered by driving the rotation motor 113, and slats 112 are stacked on the upper surface of the lower bar 111 to open and close the opening. At this time, the angle formed by the slat 112 changes depending on the rotation direction of the rotation motor 113. In order to change the angle formed by the slat 112, the rotation motor 113 is driven in the forward or reverse direction, and the slat 112 ) As the angle changes, the bottom bar 111 also rises and falls.

The slat 112 rotates only within a randomly set angle range, and when the slat 112 reaches the set angle range, the rotation of the slat 112 is stopped and only the lower bar 111 is raised and lowered. Such a blind 110 is an electric blind that is automatically opened and closed by a rotation motor 113, and corresponds to a known electric blind. (Refer to Registered Patent Publication No. 10-1211959, Registered Patent Publication No. 10-1884509)

The position identification unit 200 is provided on one side of the rotation motor 113 and is connected to the rotation motor 113 to detect the rotation speed and rotation direction of the rotation motor 113. The position identification unit 200 is an encoder sensor that is a sensor for detecting rotational motion, and may preferably correspond to a rotary encoder. Therefore, 360° is divided at a certain ratio based on the 0° point of the rotation axis of the rotation motor 113, and the rotation angle of the rotation motor 113 is detected for each divided angle to determine the raising and lowering distance of the lower bar 111. The rotation angle of the slat 112 can be calculated.

The position setting unit 300 is linked with the position identification unit 200 and receives the moving distance of the lower bar 111 and the rotation angle data of the slat 112 obtained from the position identification unit 200. The positioning unit 300 allows the user to select any one blind 110 among the blinds 110 grouped in the blind unit 100, and determines the position of the lower bar 111 of the selected blind 110 and the slat 112. ) Set the reference position of the blind 110 preferred by the user, including the angle.

If described in more detail with reference to FIG. 3 , the position setting unit 300 includes a temporary setting unit 310, an alignment unit 320, an angle setting unit 330, and a reference position storage unit 340.

The temporary setting unit 310 performs a process in which the user operates the terminal 20 connected to the cloud server 10 connected online and moves the bottom bar 111 of the selected blind 110 to a temporary position. The terminal 20 may correspond to a smartphone, etc., and selects one blind 110 among a plurality of blinds 110 by driving and manipulating an application installed on the smartphone, and selects the selected blind 110. In order to move the bottom bar 111 to the user's desired position, an operation signal is transmitted to the rotation motor 113. That is, the purpose is to allow the user to arbitrarily set the degree of opening of the opening by raising and lowering the lower bar 111.

The purpose of the alignment unit 320 is to align the angle of the slat 112 by rotating the slat 112 in one direction when the lower bar 111 of the selected blind 110 is completed moving to the temporary position set by the user. has

Referring to FIG. 4 , it is assumed that one end of the slat 112 is the reference point (P) of the slat 112. When the alignment unit 320 aligns the angle of the slat 112, the slat 112 is rotated to correspond to (a) of FIG. 4 and the reference point P reaches the lowest position. When the rotation motor 113 is driven to lower the lower bar 111 by a predetermined distance, the reference point P of the slat 112 may reach the lowest position.

The case corresponding to (b) of FIG. 4 shows a state in which the reference point (P) of the slat 112 has reached the highest position when the bottom bar 111 is raised and positioned at the temporary position, and the alignment portion ( 320) is driven when the lower bar 111 rises and the reference point (P) of the slat 112 reaches the highest position, or when the reference point (P) of the slat 112 is located between the highest and lowest positions. It operates only to move the reference point (P) of the slat 112 to the lowest position to align the slat 112. Due to this, the reference position of the slat 112 can be set, and when the setting of the temporary position of the lower bar 111 is completed, the alignment unit 320 can align the slat 112 without separate manipulation by the user.

Meanwhile, when the lower bar 111 descends and reaches the temporary position, the reference point P of the slat 111 remains at the lowest position, so the operation of the alignment unit 320 can be omitted.

When the slat 112 reaches the lowest position, the angle setting unit 330 transmits an operation signal so that the user drives the rotation motor 113 so that the reference point P of the slat 112 is located between the lowest and highest positions. Rotate the slat 112 to set the angle of the slat 112 to the user's preferred angle.

The set position of the slat 112 corresponds to the reference angle of the slat 112. At this time, the slat 112 can be rotated so that the reference point P of the slat 112 reaches the divided position by dividing the space between the lowest position and the highest position at an arbitrary angle. The dividing angle is preferably set to 30°, and the user can set it in various ways, such as 10° or 20°.

Referring to FIG. 3, the slats 112 are aligned in the angle setting unit 330, and a change in the position of the bottom bar 111 occurs in the process of setting the reference angle of the slat 112. That is, when the slats 112 are aligned after the lower bar 111 rises and reaches the temporary position, the lower bar 111 first descends a predetermined distance d1 from the temporary position.

And, in the process of setting the slat 112 as the reference angle, the bottom bar 111 rises a predetermined distance (d2). Afterwards, the reference position storage unit 340 stores the current position of the bottom bar 111. As a result, the reference position of the lower bar 111 and the reference angle of the slat 112 can be stored. Then, when the reference position of the lower bar 111 is set, the position identification unit 200 can indicate the current position of the lower bar 111 by converting the reference position of the lower bar 111 into numbers as a percentage.

Referring to Figures 5 and 6, the operation control unit 400 is linked with the location identification unit 200 and receives data from the location identification unit 200. of the unselected blind 110 so that the unselected blind 110 can have the position of the lower bar 111 and the angle of the slat 112 that are the same as the angle of the lower bar 111 and the slat 112 of the selected blind 110. Controls the operation of the rotation motor (113).

The operation control unit 400 further includes a position confirmation unit 410, a temporary moving unit 420, a slat alignment unit 430, and a slat angle setting unit 440.

The position confirmation unit 410 identifies the position of the bottom bar 111 of the unselected blind 110. By identifying the position of the bottom bar 111 of the unselected blind 110, the position confirmation unit 410 detects whether the bottom bar 111 is descending or rising when moving to the reference position, and the bottom bar 111 is When descending, a specific signal is generated so that the slat alignment process of the slat alignment unit 430 can be omitted. If a specific signal is generated and the slat alignment process is omitted, there is an advantage that the alignment process of the blinds 110 can be performed quickly.

The temporary moving unit 420 moves the lower bar 111 of the unselected blind 110 to the same position as the reference position of the lower bar 111 set in the selected position setting unit 300. (See Figure 5(b))

The slat alignment unit 430 rotates the slat 112 of the unselected blind 110 so that the reference point P of the slat 112 faces the lowest position. That is, when the position of the lower bar 111 of the unselected blind 110 is located lower than the reference position of the selected lower bar 111 and the lower bar 111 rises, or the lower bar 111 is at the reference position. When the reference point (P) of the slat (112) is not located at the lowest position when it is reached, the reference point (P) of each slat (112) of the selected blind (110) and the unselected blind (110) is selected so that it is located at the lowest position. The rotation motors 113 of each of the blinds 110 and the unselected blinds 110 are driven to rotate (align) the slats 112.

That is, when each rotation motor 113 is driven so that the reference points (P) of each slat 112 of the selected blind 110 and the unselected blind 110 are located at the lowest positions, the selected blind 110 and the unselected blind 110 The positions of the slats 112 and the bottom bar 111 of the blind 110 are in the same state. (See Figure 5(b), Figure 6)

Thereafter, the slat angle setting unit 440 transmits an operation signal to the rotation motor 113 of each of the unselected blinds 110 and the selected blinds 110 to set the reference angle of the slat 112 set in the position setting unit 300. Rotate the slat (112). Accordingly, the bottom bar 111 and slat 112 of the selected blind 110 and the unselected blind 110 may have the same height and angle values. (see Figure 7)

Meanwhile, the operation control unit 400 further includes an equalization control unit 450. The equalization control unit 450 is configured to align the selected blinds 110 and the unselected blinds 110 so that the positions of the lower bars 111 of the selected blinds 110 and the unselected blinds 110 have the same position values when aligning the slat alignment unit 430. An operation signal is transmitted to the rotation motor 113 of the blind 110, respectively.

That is, when the bottom bar 111 of the unselected blind 110 reaches the reference position, the slats 112 of the selected blind 110 and the unselected blind 110 may maintain different angles. (see Figure 5)

As a result, a time difference occurs for the reference point P of each slat 112 of the selected blind 110 and the unselected blind 110 to reach the lowest position. At this time, the equalization control unit 450 controls the lower bar of the blind 110 in which the reference point (P) of the slat 112 reaches the lowest position first and the blind 110 in which the reference point (P) of the slat 112 reaches the lowest position later. The position difference of (111) is calculated as the rotation value of the rotation motor (113).

That is, the rotation motor 113 of the blind 110, where the reference point P of the slat 112 reaches the lowest position first, is further driven by the calculated difference value. Therefore, first, the position of the bottom bar 111 of the blind 110 where the reference point P of the slat 112 reaches the lowest position, and later, the position of the bottom bar 111 of the other blind 110 where the reference point P of the slat 112 reaches the lowest position. The position of the bottom bar 111 may have the same position value.

Thereafter, the slat angle setting unit 440 rotates each slat 112 of the selected blind 110 and the unselected blind 110 to the reference angle.

The blind automatic control system having this configuration can uniformly align a plurality of irregularly opened blinds with the height of one blind and the angle of the slat as a reference.
