TECHNICAL FIELD [0001] The present invention relates to a streetlight system having a fine dust notification function using a beacon,

The present invention relates to a streetlight system, and more particularly, to a streetlight system which includes a fine dust sensor on at least one of a plurality of streetlight devices capable of illuminating in various colors, and provides fine dust measurement information using beacons between streetlight devices To a streetlight system using the beacon to illuminate the streetlight device with different colors corresponding to the fine dust prediction reference according to the fine dust measurement information, and a method thereof.

Recently, the distribution of fine dust in the air is increasing nationwide, especially in the spring when yellow dust occurs, the damage is increasing exponentially. Fine dust can penetrate into the human body and cause disease. Depending on its size, the amount of fine dust can be filtered out from the human body. PM-10 is a dust that has a diameter of 10㎛ or less and it is often called PM-10 in the environmental regulation. PM-10 penetrates deeply into the alveoli of a person and becomes a direct cause of various respiratory diseases. Especially, It is composed of harmful substances such as metal compounds, carbon compounds and ion components such as sulfate, nitrate and ammonia.

For this reason, regulations are strictly regulated more than general dust, and in advanced countries, management of PM-25 with diameters of less than 25 ㎛ is under consideration. The heavy metals in the constituent materials do not escape to the body but accumulate in the human body, causing diseases caused by heavy metal poisoning, and small dust particles penetrate into the cell wall and invade into the cells, causing inflammation.

The analysis of the size distribution and composition of fine dusts that adversely affect us in the air where various fine materials are mixed is necessary for us to take measures against damage caused by fine dust. Therefore, if we can measure the change of state of air according to time in the space that we want in real time, it will be a great help to establish appropriate countermeasures. Especially at night, it is difficult to visually check the air quality such as fine dust near the living area.

[ Subsequently, the procedure proceeds to step S400 and repeats the above-described processes (S400 to S408) in real time or periodically.

The second lamp unit 210 receives the control signal from the first lamp unit 200 via the beacon 216 and transmits the control signal to the LED lighting unit 218 to generate the corresponding fine dust, .

However, if the control signal indicates that the fine dust generation condition is bad or is very bad, the procedure goes to step S414 so that the LED lighting unit 208 displays the fine dust occurrence state, that is, poor or very bad, And transmits a beacon signal corresponding to the control signal to the second streetlight device 210 using the beacon 206. [

The first streetlight device 200 recognizes the user terminal 300 located in the vicinity of the installation site of the first streetlight device 200 using the beacon 206 in step S416 and generates fine dust The notification information corresponding to the situation (that is, the case where the fine dust prediction reference information is not less than a predetermined value (for example, poor or very bad) is transmitted.

When the beacon signal is transmitted from the first streetlight device 200 in step S420, the second streetlight device 210 recognizes the user terminal 300 located around the installation site of the beacon using the beacon 216, The notification information corresponding to the fine dust generation state, that is, the notification information corresponding to the case where the fine dust prediction reference information is not less than a preset value (for example, poor or very bad) is transmitted to the user terminal 300 recognized in step S422.

Then, in step S424, the user terminal 300 receives the beacon signal from the first or second lamp unit 200 or 210 to display notification information corresponding to the fine dust generation state, that is, poor or very bad. Accordingly, a user located in the vicinity of the first and second streetlight devices 200 and 210 can confirm the notification information without using the LED lighting units 208 and 218 and take appropriate measures.

The processing procedure of the street lamp system 2 of the present invention described above is repeated in real time or periodically. Therefore, the streetlight system 2 of the present invention can notify the user of the occurrence of fine dusts at nighttime as well as during the daytime.

In addition, in the embodiment of the present invention, it has been described that the minute dust generation situation is reported using the streetlight device. However, instead of the streetlight device, a plurality of lighting devices (for example, Landscape lighting, etc.) can be used to implement the same functions and actions. In this case, the illumination device may include a plurality of light emitting diodes and may be illuminated in various colors, and the fine dust sensor may be installed outside the illumination device to measure minute dust concentration in real time or periodically and provide the illumination device .

Accordingly, the present invention can be implemented not only in a streetlight device, a lighting device, but also in a variety of alarm devices, so that the risk of fine dust can be informed in various ways.
