FIG. 1 shows an example of an energy saving system to which a wireless network-based LED lighting control and operation method for energy saving according to the present invention can be applied.

The ambient light sensor detects ambient light brightness and automatically adjusts the brightness of the LED light according to the selected reference value, maximizing the energy saving effect. It automatically dims to maximum / minimum brightness by external illumination. And when the fuselage sensor does not have a car or a moving person around for a certain period of time, the LED light is turned off or kept at the minimum brightness state to save energy.

FIG. 2 is a block diagram illustrating a configuration of a system to which a wireless network-based LED lighting control and operation method for energy saving according to the present invention is applied. The central control system 200 controls the LED lighting device 210 through wireless communication. The illuminating devices 210, 220, 230, 240, 250, and 260 may include an illuminance sensor, a motion sensor, and a wireless communication module. The central control system 200 and the LED lighting devices 210, 220, 230, 240, 250, 260 or the LED lighting devices 210, 220, 230, 240, 250, . The short-range wireless communication may be Bluetooth, Zig bee, WiFi, NFC, or the like.

In order for LED lighting to perform autonomous automatic control and central monitoring to save energy, it is necessary that the controller consisting of sensor, control, and communication is designed to control the illumination individually. The controller may be the central control system 200 or may be the control unit 214 of the illumination itself. In order to save energy, it is necessary to collect and control the information of the motion sensor such as the ambient illuminance, the user's motion intensity, and the frequency of the LED illumination which changes in real time in order to optimize the illumination control in various environments. The central control system 200 makes an intelligent judgment The control unit 214 of the LED lighting apparatus 210 may automatically control the LED lighting 212 by performing an intelligent determination by itself.

FIG. 3 is a flowchart illustrating a wireless network-based LED lighting control and operation method for energy saving according to an exemplary embodiment of the present invention. A method of controlling and operating a wireless network-based LED lighting for energy saving according to an embodiment of the present invention will be described with reference to FIGS. 2 and 3. FIG.

First, in the embodiment of the present invention, various control algorithms are provided by using illuminance and motion sensor information mounted on the LED lighting to autonomously control the LED illumination. (Step S310) In the embodiment of the present invention, For example. But is not limited to the five control algorithms of the present invention.

In the embodiment of the present invention, the autonomous illumination mode, the master illumination mode, the illumination priority composite mode, the motion priority composite mode, and the motion frequency priority composite mode are provided by the five control algorithms. In the present invention, by intelligently and selectively using at least one of the five control algorithms, it is possible to make intelligent decisions and efficiently save energy.

The autonomous illumination mode is a first method, which obtains illuminance information of illumination through an illuminance sensor, and controls the illumination to be darker when the illuminance of the surroundings is brighter than the illuminance of the illumination, And when it is dark, the illumination is controlled to be bright so as to maintain a desired level of illumination level, thereby saving energy and maintaining a comfortable indoor illumination level.

The master illumination mode is a second mode in which a specific illumination in a lighting group consisting of a plurality of lights is preset as a master illumination and the lights other than the master illumination are illuminated in a slave illumination , The brightness of the master illumination and the number of slave lights are kept the same, and the brightness is controlled according to the surrounding illuminance in units of a specific zone to maintain the optimum illuminance. For the master illumination mode, a new desired LED lighting node is set as a master node, a group ID corresponding to the master node is set, a group ID corresponding to the slave nodes is set for the slave nodes, Can be changed.

The illumination-priority composite mode is a third method, which uses a motion sensor, but controls the LED lighting to be non-bright even when motion is detected by the motion detection sensor when the ambient illumination of the LED illumination is brighter than the LED illumination, . In the illumination-priority composite mode, when the ambient illuminance of the LED illumination is darker than the LED illumination, the LED illumination is controlled to be brighter when motion is detected by the movement sensor.

The movement priority composite mode is a fourth mode in which when the movement is not detected by the movement sensor mounted on the LED illumination, energy is saved while maintaining the illuminance level of the LED illumination according to the ambient illuminance of the LED illumination, The LED lighting is controlled to be brighter so as to save energy and improve user convenience.

The motion frequency priority composite mode is a fifth mode. If the LED illumination is bright around the LED illumination similar to the third option, the illuminance of the LED illumination is maintained, but when the frequency of motion detection is increased by the movement sensor And third and fourth way hybrid methods for controlling the LED illumination such that the LED illumination is brightened for user convenience as in the fourth method.

The controller uses five LED lighting control algorithms to control and monitor multiple LED lights. That is, the plurality of LED lights are controlled by selectively using the five control algorithms based on the light intensity sensor and the motion sensor information (step S320)

For example, the plurality of LED lights may be controlled using at least one of an autonomic illumination mode and a master illumination mode, and at least one of the five control algorithms may be used to control the LED illumination.

Meanwhile, each of the lighting nodes is set as a group through the plurality of LED lights or a network connected to the central control system, and each of the lighting nodes is configured in a lighting control mode composed of a plurality of groups to constitute a separate group ID And may be operated by ON / OFF or manual illuminance control in step S330.

For such complex and autonomous control, there is a need for a group concept for grouping and controlling each lighting node in a network connected to lighting or a central control system. In the conventional method, since a single light has one group name, group control is possible, but it is not possible to have a plurality of groups, so a separate logical control group must be programmed to the central control or a plurality of groups must be controlled by the user.

The present invention includes the following features. First, in the autonomous control, each of the illumination nodes may be set in a plurality of groups. That is, by belonging to the illumination control mode capable of setting the overlapping group, a separate group ID is configured for the illumination nodes to be applied when a new autonomous control service is added, so that the efficient operation can be performed without changing the existing group configuration and withdrawal.

Secondly, in the case of the master illumination mode (second scheme), a group ID is designated as a master node and a group ID of a second plan set in the remaining slave node is input, It is easy to change to the master illumination mode without changing the group IDs.

FIG. 4 illustrates an example of setting and controlling a group of a plurality of LED lights in a wireless network-based LED lighting control and operation method for energy saving according to an exemplary embodiment of the present invention, Respectively.

Referring to FIG. 4, groups 1, 2, 3 and 4 (422, 424, 426, and 428), which are location-based individual groups, are groups set according to the management and concurrent control frequency. Group 5 410 is a group that operates in the master illumination mode and includes a master 142 and a slave 414 and controls the external illuminance influx into the window 460 to a group that is controlled according to the illumination of the master 412 to be. Group 6 (420) is a group that operates in the autonomous illumination mode and is autonomously controlled according to the ambient illuminance.

It is possible to control the illumination parameters such as the target illuminance, the ON / OFF and the manual illuminance control easily in each group, thereby enabling efficient LED lighting operation. A illumination 412 is the master illumination of group 5 410 and has group 1 422 and group 5 410 controlling group 1 412 illumination to a range and group 5 410 410 Can be controlled by using. By doing so, space-specific control and multiple redundant control are possible, which makes it possible to efficiently and precisely save energy by not driving unnecessary illumination more precisely.

On the other hand, when the group ID is set, a message for the operation is received from the controller after the group ID is set. If the group ID information set in the message is matched, a corresponding operation can be performed. LED lighting devices can have individual IDs and group IDs, and can add or delete group IDs in multiple redundant ways.

In the master illumination mode, illumination values of the illumination are read from the illumination sensor through the network, and the illuminance values of all the illumination nodes of the group to which the master belongs are unified to the master illumination value so that the lights in a certain area are adjusted to the same illumination value It may be possible. For example, if the master light is located at the window, all of the lights in the group can be kept at the same illumination value as the master light according to the window illumination.

The present invention can be implemented as a computer-readable code on a computer-readable recording medium (including all devices having an information processing function). A computer-readable recording medium includes all kinds of recording apparatuses in which data that can be read by a computer system is stored. Examples of computer-readable recording devices include ROM, RAM, CD-ROM, magnetic tape, floppy disk, optical data storage, and the like. Also, in this specification, the term " part " may be a hardware component such as a processor or a circuit, and / or a software component executed by a hardware component such as a processor.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art. Accordingly, the true scope of the present invention should be determined by the technical idea of the appended claims.
