Description

광센서에 의한 전동 블라인드 승강 제어장치{Controlling apparatus of electromotive blind using photoelectron sensor}BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an electric blind elevation control device using an optical sensor,

본 발명은 전동 블라인드에 관한 것으로, 특히 전동 모터를 이용하여 블라인드를 상측으로 접을 경우에 블라인드의 승강 높이를 감지하여 설정된 높이에 도달하면 모터의 작동을 즉시 중지하여 블라인드의 작동시 유격이 발생하는 것을 방지하면서도 모터의 과작동을 방지토록 한 것이다.The present invention relates to an electric blind, and more particularly, to an electric blind, particularly when an elevation height of a blind is detected when an electric motor is used to fold the blind upward, And prevent the motor from overheating.

일반적으로 블라인드는 창문을 통해 비춰지는 직사광선을 차단하고, 실내의 상황을 외부로 노출시키지 않도록 차단하는 역할을 하기 위하여 사용되는 것으로, 종래에는 수동으로 승,하강 되는 블라인드가 주로 사용되었으나, 최근에는 모터의 작동에 의하여 승,하강 되면서 블라인드의 각도를 조절할 수 있는 전동 블라인드의 사용이 점차 늘어나고 있다.In general, blinds are used to cut off direct sunlight shining through a window and to prevent the indoor situation from being exposed to the outside. Conventionally, blinds that are manually raised and lowered are mainly used, but in recent years, The use of electric blinds capable of adjusting the angle of the blinds while being raised and lowered by the operation of the electric blinds is gradually increasing.

이러한 블라인드의 일반적인 구조는 블라인드의 구동을 위한 승강장치가 상측에 마련되고, 상기 승강장치에 다수의 슬래트가 승강 줄 및 사다리 줄에 의하여 연결되어 승강장치를 구동시키면 승강 줄 및 사다리 줄에 의하여 슬래트가 승, 하강되며 각도조절을 할 수 있게 되는 것이고, 특히 전동 블라인드에서는 블라인드가 올라갈 때, 블라인드가 상한 위치로까지 상승하면 전동모터를 정지시키기 위한 제어수단이 형성되어 모터가 필요 이상으로 회전하는 것을 방지하면서 모터과 과열되지 않고 안정적인 승,하강이 이루어질 수 있도록 하는 것이다.In the general structure of such a blind, a lift table for driving the blind is provided on the upper side, and when a plurality of slats are connected to the lift device by a lift bar and a ladder bar to drive the lift device, In particular, in the case of the electric blind, when the blind rises to the upper limit position, a control means for stopping the electric motor is formed to prevent the motor from rotating more than necessary, So that stable up and down can be achieved without overheating.

하지만, 이러한 것의 문제가 종래의 블라인드 구조물의 블라인드 제어 장치는 블라인드의 전개 또는 회수 길이를 조작하는 방식으로, 모터의 회전수를 계측하여 블라인드가 설정한 상한 위치까지 상승하면 모터의 작동을 중지토록 하는 방식이 사용되는데, 이 경우 블라인드의 전개 또는 회수 길이를 제작 단계에서 미리 설정하기 때문에 임의의 길이 설정 및 변경이 불가능한 것이다.However, a problem with such a conventional blind structure is that the blind control device of the blind structure manipulates the development or recovery length of the blind, measures the rotation number of the motor, and stops the operation of the motor when the blind rises to the upper limit position In this case, since the length of development or recovery of the blind is set in advance in the production step, it is impossible to set and change an arbitrary length.

그리고 블라인드의 상승을 제한하는 또 다른 방법으로 기계식 스위치를 이용하여 슬래트의 접힘 상태를 감지하는 방식으로, 상부틀의 하단에 버튼식의 스위치를 장착하여 슬래트가 상부틀의 하부까지 밀착되게 상승할 경우 슬래트가 버튼을 눌러주게 되면서 모터의 작동을 중지토록 하는 방식이 사용되는데, 이 경우에는 버튼의 유격이나 슬래트가 스위치를 누르는 압력에 따라 반응속도에 차이가 발생할 수 있으며, 스위치의 누름과 제어기판의 작동관계를 조절하기가 매우 어려운 것이다.Another method for restricting the rise of the blind is to detect the folded state of the slat by using a mechanical switch. When the button switch is attached to the lower end of the upper frame and the slat rises up to the lower portion of the upper frame In this case, there may be a difference in response speed depending on the clearance of the button or the pressure at which the slat is pressed by the switch. In this case, when the switch is pressed and the control board It is very difficult to control the working relationship.

특히, 블라인드가 상승할 때 모터의 단속이 늦어지면 정위치에서 슬래트의 상승을 중지시킬 수 없어서 사용할 때마다 오차가 발생될 우려가 있고, 복수의 블라인드를 병렬로 설치할 경우에 각각의 블라인드가 접힌 상태의 높낮이가 달라져서 미관상 보기 좋지 않을 뿐만 아니라, 품질을 저하시키게 되는 것이다.Particularly, when the intermittent speed of the motor is slowed down when the blind rises, it is impossible to stop the rising of the slats in the right position, and there is a fear that an error is generated every time the blind is used. In the case where a plurality of blinds are installed in parallel, Not only the appearance is not good but also the quality is deteriorated.

또한, 이 경우 모터가 필요 이상으로 작동하면서 모터에 과부하가 걸리게 되거나, 또는 스위치 및 슬래트 등과 같은 블라인드의 부속이 파손될 우려가 있고, 이러한 것이 반복될수록 결국에는 제품의 오작동 및 하자가 발생하게 되는 원인이 되는 것이다.Further, in this case, there is a fear that the motor is overloaded due to excessive operation of the motor, or the blind parts such as the switch and the slats are damaged. .

따라서 본 고안은 블라인드의 슬래트를 상측으로 접을 때 슬래트가 설정한 높이값에 이르게 되면 모터의 작동을 즉시 중지시키고, 이러한 모터의 제어가 설정위치에 민감하게 반응토록 하여 유격이 발생됨 없이 정위치 중지되어 안정적인 블라인드의 승,하강 제어가 이루어지도록 한 것이다.Therefore, the present invention immediately stops the operation of the motor when the slat reaches the set value when the slat of the blind is folded upward, and the control of this motor is sensitive to the set position and stops positively So that a stable blind can be controlled to be raised and lowered.

이를 위하여 본 고안은 모터와 제어기판이 상부틀에 내장되어 컨트롤러의 작동에 의하여 모터를 회전시켜 슬래트를 접거나 폄으로써 블라인드가 승,하강 작동되는 것에 있어서, 빛 발산이 이루어지는 발광부와 빛을 측정하는 감지부로 이루어지는 광센서를 상부틀에 장착하고, 상기 발광부와 감지부를 각각 하측 방향으로 설치하면서 서로 대응되게 경사지도록 장착하여 발산되어진 빛이 최상단 슬래트의 상면에 반사되어 감지부로 유입되면 모터의 작동을 중지토록 한 것이다.For this purpose, in the present invention, the motor and the control board are built in the upper frame, and the blind is moved up and down by rotating the motor by the operation of the controller to fold or unfold the slats. And the sensing unit is mounted on the upper frame so that the light emitting unit and the sensing unit are disposed in the lower direction and are inclined corresponding to each other. When the diverged light is reflected on the upper surface of the uppermost slat and flows into the sensing unit, .

또한, 상기 발광부와 감지부의 설치각도나 발광부와 감지부가 서로 이격된 거리를 조절함으로써 광센서와 슬래트의 근접정도, 즉 승강 설정높이를 조절할 수 있도록 한 것이다.In addition, the proximity of the light sensor and the slats, that is, the elevation setting height, can be adjusted by adjusting the installation angle of the light emitting unit and the sensing unit and the distance between the light emitting unit and the sensing unit.

또한, 상기 슬래트는 표면에 반사율이 높은 재질의 시트를 덧씌우거나, 또는 반사율이 높은 코팅층을 도장함으로써 감지부의 인식률을 향상시키도록 한 것이다.In addition, the slats are provided to improve the recognition rate of the sensing portion by overlaying a sheet having a high reflectance on the surface thereof or by coating a coating layer having a high reflectance.

따라서 본 고안은 승, 하강시 유동없이 원활하고 안정적으로 작동되어 장기간 사용시에도 블라인드의 불량이나 하자발생률을 줄일 수 있고, 정확한 작동제어로 인하여 모터의 과부하를 줄여 제품의 수명을 연장시킬 수 있으며, 블라인드를 상측으로 올려 접을 경우 정위치에서 슬래트의 승강이 중지되므로 블라인드의 접힘 정도를 균일하게 할 수 있고, 또한 이러한 승,하강의 제어를 위한 수단이 외부로 노출되지 않으므로 미관을 수려하게 할 수 있는 것이다.Accordingly, the present invention can smoothly and stably operate without waking up and down during the lifting and lowering, thereby reducing the blind defects and defects in long-term use, and can reduce the overload of the motor due to accurate operation control, The folding of the blinds can be made uniform, and the means for controlling such rising and falling can not be exposed to the outside, so that the aesthetic appearance can be enhanced.

이하 본 발명에 따른 바람직한 실시 예를 첨부한 도면을 참조하여 설명하면 다음과 같다. Hereinafter, preferred embodiments according to the present invention will be described with reference to the accompanying drawings.

일반적인 전동 블라인드의 구조는, 다수의 슬래트(100a,100b...100n)가 승강 줄(110)과 사다리 줄(120)에 의하여 상부틀(200)에 고정되고, 상부틀(200)은 천정이나 창문의 상부에 고정 설치되며, 상부틀(200)의 하단으로 늘어지게 설치되어진 슬래트(100)가 상부틀(200)에 내장된 모터(310) 및 제어기판(320)으로 이루어지는 승강장치(300)에 의하여 승, 하강 및 각도조절이 이루어지도록 되는 것으로, 상부틀(200)의 내부에 장착되는 승강장치(300)는 유선상 또는 무선상으로 연결되는 컨트롤러를 이용하여 승강장치를 구동하게 되는 것이다.The general structure of the electric blind is such that a plurality of slats 100a, 100b ... 100n are fixed to the upper frame 200 by the lift rope 110 and the ladder rope 120, The slat 100 installed on the upper part of the window and slidably installed at the lower end of the upper frame 200 includes the elevator 300 composed of the motor 310 and the control board 320 built in the upper frame 200, And the elevation device 300 mounted inside the upper frame 200 drives the landing gear using a controller connected to the wired or wireless network.

즉, 컨트롤러에서 발신된 신호에 따라 모터의 작동을 제어하여 블라인드를 승하강시키게 되는데, 본 고안은 도 1에 도시된 바와 같이 상부틀(200)에 광센서(10)를 내장하여 하측으로 발광시킴으로써 최상단에 위치한 슬래트(100a)와 상부틀(200)간의 근접거리를 측정하여 설정한 간격에 도달하면 모터(310)의 작동을 즉시 중지토록 한 것이다.That is, according to a signal transmitted from the controller, the operation of the motor is controlled to move up and down the blind. In the present invention, as shown in FIG. 1, the optical sensor 10 is built in the upper frame 200, The close distance between the upper frame 200 and the slats 100a positioned at the upper end is measured and the operation of the motor 310 is immediately stopped when the interval is reached.

이때, 상기 광센서(10)는 빛이 발광되는 발광부(11)와 그 빛을 감지하는 감지부(12)로 이루어지도록 하면서, 상기 발광부(11)와 감지부(12)의 장착구조를 서로 마주보는 형태로 하측 방향으로 경사지게 장착하면 도 2a에 도시된 바와 같이 발광부(11)에서 발산된 빛이 최상단 슬래트(100a)의 상면에 부딪혀 상측으로 반사되는데, 이때 도 2에 도시된 바와 같이 최상단 슬래트(100a)가 설정된 높이에 도달하게 되면 반사된 빛이 감지부(12)에서 인식할 수 있게 되는 것이다.The light sensor 10 includes a light emitting unit 11 for emitting light and a sensing unit 12 for sensing the light and a mounting structure of the light emitting unit 11 and the sensing unit 12 As shown in FIG. 2A, the light emitted from the light emitting portion 11 hits the upper surface of the uppermost slat 100a and is reflected upward, as shown in FIG. 2A. At this time, When the uppermost slat 100a reaches the set height, the reflected light can be recognized by the sensing unit 12. [

따라서 감지부(12)에서 빛을 감지하면 모터(310)의 구동을 중지시키도록 제어기판(320)으로 신호를 보내게 되는 것이고, 이러한 모터(310)의 작동제어가 빛에 의하여 이루어지므로 오차를 최소화할 수 있고, 설정된 위치에 도달하는 즉시 모터의 작동을 중지시켜 블라인드의 정밀한 작동이 가능토록 한 것이다.Accordingly, when the light is sensed by the sensing unit 12, a signal is sent to the control board 320 to stop the driving of the motor 310. Since the operation control of the motor 310 is performed by light, The motor can be stopped and the blind can be precisely operated as soon as the set position is reached.

이때, 상기 광센서(10)는 상부틀(200)의 하단에 노출되어지는 형태로 부착하여 형성할 수 있으나, 더욱 바람직하게는 상부틀(200)의 내공간에 내입한 상태에서 상부틀(200)의 하단부에 절개부(210)를 형성하여 빛이 투과될 수 있도록 함이 바람직한 것이고, 이때 상기 절개부(210)에는 투명막을 씌워 광센서가 외부에 직접 노출되는 것을 방지토록 할 수 있는 것이다.In this case, the optical sensor 10 may be attached in a form to be exposed at the lower end of the upper frame 200, but more preferably, in a state of being inserted into the inner space of the upper frame 200, It is preferable that a cut-out portion 210 is formed at the lower end of the cut-out portion 210 so that light can be transmitted. At this time, the cut-out portion 210 is covered with a transparent film to prevent the optical sensor from being directly exposed to the outside.

한편, 상기 최상단 슬래트(100a)의 상한 위치를 설정하는 방법으로는 도 3 및 도 4에 도시된 바와 같이 발광부(11)와 감지부(12)의 설치각도(A)를 제어하거나, 또는 발광부(11)와 감지부(12)의 서로 이격된 거리(D)를 조절함으로써 반사각(α)을 조절할 수 있는 것이고, 이러한 반사각(α)을 조절함으로써 광센서(10)와 슬래트의 근접정도, 즉 슬래트의 승강시 설정높이를 조절할 수 있게 되는 것이다.The uppermost position of the uppermost slat 100a may be set by controlling the installation angle A of the light emitting unit 11 and the sensing unit 12 as shown in FIGS. 3 and 4, It is possible to adjust the reflection angle alpha by adjusting the distance D between the optical sensor 10 and the sensing unit 12. By adjusting the reflection angle alpha, That is, it is possible to adjust the set height when the slat is lifted or lowered.

또한, 상기 최상단 슬래트(100a)는 발광부(11)에서 발산된 빛의 반사율을 높이고, 감지부(12)에서의 인식률을 높이기 위하여 슬래트의 표면에 반사시트를 덧씌우거나, 또는 반사코팅층을 도장하여 더욱 정확하고도 안정적인 작동이 이루어질 수 있도록 할 수 있는 것이다.The uppermost slat 100a may be formed by overlaying a reflective sheet on the surface of the slat or by applying a reflective coating layer to increase the reflectivity of the light emitted from the light emitting portion 11 and increase the recognition rate of the sensing portion 12 So that more accurate and stable operation can be achieved.
