Description

TECHNICAL FIELD [0001] The present invention relates to a smart lighting control method based on wireless communication,

The present invention relates to a smart lighting control method based on wireless communication, and more particularly, to a smart lighting control method based on wireless communication, and more particularly, To a smart lighting control method based on wireless communication.

In general, incandescent lamps, fluorescent lamps, and triple-wavelength lamps have been used as lighting devices. However, since the life span is short and energy is consumed in a large amount, ultraviolet rays harmful to human bodies are detected in the emitted light and argon gas and helium gas The environmental pollution problem is also serious.

Recently, in consideration of power consumption, lifetime of illumination, brightness, diffusion range, etc., the use of an illumination device using a light emitting diode (LED) as a light source has been increasing.

Lighting using LEDs can be applied to indoor lighting (bedroom, living room, study room, etc.), landscape lighting (buildings, bridges, Art museums, theaters, resorts, etc.), IT appliances and automobiles, store interior and display, and light therapy lighting.

The above-described LEDs are more expensive than the existing light sources and have a high initial investment cost, and it is difficult to develop the light as well as the diffusion. However, since the price of the LED device is going to be lowered in the future, the lightness of the components, simplification of the manufacturing process, If it is improved, demand and applications of LED lighting are expected to increase significantly.

In addition, modern lighting seeks not only to illuminate the light but also to incorporate the interior and artistic features of the building, creating a new market by combining imagination and creativity through scientific design.

Meanwhile, in order to maximize the lighting effect according to the surrounding environment such as installation place and position, it is preferable that the lighting device using the LED is irradiated with light in a certain area. For this purpose, So that light can be irradiated to a desired area.

Such a lighting apparatus includes a lighting unit and a bracket for mounting a lighting unit to the fixing member, and the lighting unit is fixed to the bracket after the lighting unit is adjusted to a desired angle.

However, in the lighting apparatus having the angle adjustment of the prior art, since the bracket is a structure in which the lighting unit is simply bolted, the fastening force of the bolt may be deteriorated by an external physical impact. In this case, the angle of the lighting unit coupled to the bracket may not be maintained and may be shifted to a direction parallel to the horizontal plane by turning at an angle with respect to the horizontal plane. In particular, the heavier the weight of the lighting unit, the greater the frequency of such problems.

In addition, in the case of the conventional art, the angle of the illumination unit can be set only at the initial installation, and in order to adjust the angle again, there is a problem that the operator has to input the angle by using the tool.

In addition, the prior art is structurally problematic in that the illumination unit is fastened by a bolt, which is poor in appearance, difficult to control the concentration and diffusion of illumination, and difficult to automate the angle control of illumination.

Conventionally, a method of using a button of a control device connected with an illumination and a wire to control the illumination has been mainly used. However, since the control device is in a fixed position, there is an inconvenience that the user must operate and operate the control device.

However, the present invention is not limited to the embodiments described below, but may be embodied in various different forms, and these embodiments are not intended to be exhaustive or to limit the scope of the present invention to the precise form disclosed, It is provided to inform the person completely of the scope of the invention. And the terminology used herein is for the purpose of illustrating embodiments and is not intended to be limiting of the present invention. The singular forms herein include plural forms unless the context clearly dictates otherwise.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. Brief Description of Drawings FIG. 1 is a block diagram of a computer system according to an embodiment of the present invention; FIG. 2 is a block diagram of a computer system according to an embodiment of the present invention; FIG.

1 and 2, the present invention provides a lighting system comprising a lighting array 10 in which a plurality of lighting units 14 are provided in a longitudinal direction in a rectangular frame 12 having flexibility, At least one step motor (50) mounted on a ceiling with the fixing bar (30) sandwiched therebetween, and a stepping motor And a wire 70 connected to the illumination array 10 and having a vertical length varying by a rotation angle of the step motor 50. [

The present invention, which is based on the above-described configuration, includes a signal transmission step S200, a wire variable step S400, and a lighting control step S600, as can be seen from Fig.

First, in the signal transmission step (S200), the controller (90) receives a predetermined signal for controlling the illumination and transmits the signal to the step motor (50).

2, the controller 90 includes an Arduino 92 that receives an external signal and transmits a signal of the stepping motor 50 according to an algorithm defined by the apparatus, And a drive driver 94 for receiving the control signal from the inverter 92 and driving the step motor 50. [ Although the illustrated drawing shows a configuration in which the adinino 92 and the driving driver 94 are separated in a board form, the present invention is not limited thereto, and the circuit configuration of the adinino 92 and the driving driver 94 may be simultaneously integrated on one board Of course.

The Arduino 92 is an open source based hardware platform that provides an easy development environment. It has an easy-to-use development tool, a USB-based connection interface, low cost hardware, . One of the great advantages of this Arduino is that it makes it easy to operate the microcontroller. In general, AVR programming can be compiled with WinAVR and uploaded via an ISP device, which is a cumbersome process, whereas Arduino can be easily compiled and uploaded via USB. In addition, Arduino is relatively inexpensive compared to other modules, and supports various operating systems such as Windows, Mac OSX, and Linux, and since Arduino's circuit diagram is released according to CCL, anyone can directly create and modify the Arduino board . In particular, by utilizing the excellent compatibility with the operating system of the smart device, it is possible to easily control the peripheral devices such as the step motor by using the short distance communication with the Bluetooth or the NFC to provide the interactivity with the surrounding environment.

In addition, the control unit 90 is provided with a separate communication module so that bidirectional control is possible through communication with a remote server, and a drive algorithm file of the step motor 50 is directly installed in the control unit through file transfer at a remote server . Accordingly, a single server communicates with a plurality of control units to manage various facilities at a remote location, thereby reducing maintenance and labor costs.

Next, in the step of changing the wire (S400), the step motor 50 changes the length of the wire 70 by winding or unwinding the wire 70 by a predetermined length in accordance with the signal.

2 and 4, a pulley is fully engaged with the rotary shaft of the step motor 50 to facilitate winding and unwinding of the wire 70, and is connected to the pulley The rotary motion of the motor can be converted to the rectilinear motion through the wire 70. At this time, it is preferable to measure the moving distance through the rotation of the motor and optimize the diameter value of the pulley in order to minimize the error range with respect to the vertical movement of the wire 70.

The stepping motor 50 rotates by a predetermined angle every time a pulse signal is supplied. Since the number of input pulses is completely proportional to the rotation angle of the motor, the rotation angle can be accurately controlled. The step motor 50 is designed such that two coils are wound on a stator made by stacking iron plates to form two pole pairs, and the N pole and the S pole of each pole pair face each other. And the teeth integrated in the stator are distributed to function as a pole wheel.

The wire 70 is preferably made of a metal wire for securely supporting the illumination array 10, and particularly, the steel wire and the maraging wire can be twisted together to increase the durability to further improve the stability. In addition, the wire 70 made of a material such as synthetic resin or synthetic resin may be used depending on the size or the weight of the illumination array 10.

Next, in the illumination control step S600, as the length of the wire is varied, the illumination array 10 is bent with respect to the fixed bar 30 to adjust the irradiation angle of the illumination unit 14. [

Here, the frame 12 of the illumination array 10 is made of stainless steel and it is preferable that a sagging phenomenon occurs in a vertical direction in a space where gravity acts. Accordingly, in the lighting array 10, both ends are naturally bent in the vertical direction in a state where the center portion is fixed by the fixing bar 30, and the adjustment of the bending radius in the vertical direction is performed by varying the length of the wire 70 It is possible.

The illumination unit 14 of the illumination array 10 may have a plurality of RGB LEDs arranged in a dot matrix and selectively emit light in a plurality of colors. The lighting unit 14 can perform lighting functions for various purposes through various colors and brightness production, and can be used as a three-dimensional display display or an art design by avoiding conventional uniform lighting. At this time, if a plurality of RGB LEDs arranged in the dot matrix are wrapped with polycarbonate, it is possible to emit light, thereby exhibiting another illumination effect.

Furthermore, a plurality of the illumination arrays 10 may be arranged and used variously according to the functions of the indoor space or the illumination, and the respective illumination arrays 10 operate independently of each other to enable various illumination production.

Next, the fixing bar 30 allows the illumination array 10 to be supported at a certain height, one end of which is fixed to the center of the illumination array 10 and the other end of which is fixed to the ceiling of the structure. Here, the fixing bar 30 is preferably made of a steel material having high rigidity so as to more firmly support the illumination array 10.

The fixing bar 30 is fixed to the central portion of the lighting array 10 rather than simply supporting the lighting array 10 so that the fixing bar 30 can be used as a base capable of variously adjusting the bending radius of the lighting array 10 through the organic connection with the wire 70 .

The present invention according to the above can be operated as shown in Fig.

A pair of wires 70 connected to both ends of the illumination array 10 are not wound or loosened relative to the length of the fixing bar 30 and the illumination array 10 is horizontal with respect to the ground The light is evenly irradiated as a whole.

As a second operable example, a pair of wires 70 connected to both ends of the illumination array 10 are loosened so as to be longer than the length of the fixing bar 30, so that the illumination array 10 is concave The light is concentrated in a narrow space.

As a third operable example, a pair of wires 70 connected to both ends of the illumination array 10 are wound so as to be shorter than the length of the fixing bar 30, so that the illumination array 10 is convex The light spreads in a wide space.

Although not separately shown, variously combined embodiments of operable first, second, and third embodiments may be operable, in which case they may exhibit a visually pleasing interior or decoration effect as well as a role of simple illumination.

According to another exemplary embodiment of the present invention, a pattern signal transmission step (S110) of transmitting a pattern signal previously designated from a predetermined terminal to the control unit 90 may be further included. And may be a program which is algorithmized to display the illumination for the purpose of interior or display, and may be executed in a state stored in the control unit 90 and repeatedly executed.

According to another embodiment of the present invention, the sensing unit may further include a sensing signal transmitting step (S120) of sensing the object within the predetermined space and transmitting the sensed signal to the controller.

5, the sensor unit may include an ultrasonic sensor 62 and a piezoelectric sensor 64. As shown in FIG. Accordingly, the control unit 90 can track the position of the object by analyzing the signal sensed by the sensor unit and vary the length of the wire 70 so that the illumination array 10 can be illuminated in the direction of the object . Here, the sensor unit is not limited to the ultrasonic sensor 62 and the piezoelectric sensor 64, but may include all sensors that detect movement or position of the object.

That is, the illumination array 10 is not controlled in a pattern manually controlled by the user or repeated by a predetermined algorithm, but is not controlled in the pattern of the bending radius of the illumination array 10 By automatically adjusting it, it is possible to apply Kinect lighting to various fields. In other words, by moving away from the existing uniform illumination and automatically moving through the position combination of lighting according to the motion of many objects, it becomes possible to combine the creativity of the stage or the experience hall with the moving lighting of the three-dimensional form.

Here, the ultrasonic sensor 62 is a sensor that transmits ultrasonic waves to the object and receives the reflected ultrasonic waves to sense the distance and direction of the object, and may be replaced with an infrared sensor that performs the same function.

The piezoelectric sensor 64 is a sensor using a piezoelectric effect element, and conversely, an electrical pulse can be converted into vibration. Such a piezoelectric sensor can be provided on the bottom surface of the lower part of the illumination array of the present invention to sense the position of an object, and the position of the object can be detected more accurately than other sensors.

According to another exemplary embodiment of the present invention, the wireless communication unit 80 may further include a control signal transmission step of receiving a control signal from the surrounding smart device and transmitting the control signal to the control unit.

6, the wireless communication unit 80 may be installed on a ceiling or a wall where the present invention is installed in a state of being electrically connected to the controller 90. The wireless communication unit 80 may be remotely connected to a smart device or a server, To the control unit (90). At this time, the communication method of the wireless communication unit may include all short range wireless communication such as Bluetooth, NFC, WiFi, jig, etc., and the communication method may be variously changed according to the environment of the present invention or the condition of the smart device Of course.

Here, the control signal can be input from an application installed in the smart device or a program of a server, and compatible with and coordinated with the Aduino 92 of the control unit 90 described above. In particular, it is possible to control the direction of illumination as well as the various movements of the illumination through the application of the smart device, and to diversify expressions according to space and purpose.

In addition, the wireless communication unit may include a beacon that communicates with a smart device within a certain distance based on a Bluetooth protocol, and the beacon may detect the location of the smart device and transmit location information of the object to the control unit have. Accordingly, the control unit can transmit various driving signals by transmitting a predetermined driving algorithm signal to the step motor according to the position information.

When the dedicated application is installed in the smart device, the beacon is transmitted to the smart device through the BLE (Bluetooth Low Energy) which enables message transmission or mutual communication by searching for the location of the user within a radius of 50m to 70m. Technology. For example, if you go to a museum or a museum with a smart device, a web page that serves as a guide as well as providing detailed exhibition information is transferred to your smartphone.
