Disclosed is a smart street light control system using Laura communication. A smart street light control system using Laura communication according to an embodiment includes a street light including a circuit that receives an external signal to blink and adjusts the illuminance, and data measured from a plurality of sensors provided within a predetermined distance from the street light. Data collected from the plurality of sensors using a cloud server and Laura communication that generates light flashing reference data based on environmental data of the area where the street light is installed and generates a light control signal according to the generated light flashing reference data. And a street light control device that transmits the signal to the cloud server and transmits the lighting control signal generated by the cloud server to the street light, and the plurality of sensors include an illuminance sensor, a humidity sensor, a temperature sensor, an air pressure sensor, a fog detection sensor, and It includes at least one of a color sensor, the street light controller estimates the location information of the street light from the location of the Laura gateway installed within a predetermined distance from the street light, transmits the estimated location information to a cloud server, and the cloud The server further collects sunrise time, sunset time, and weather information of the day from the weather station closest to the location of the street light, and analyzes the weather information, and when the current season is spring and autumn, the air pressure sensor When the measured field pressure is compared with the standard pressure obtained at the weather station, and the value obtained by dividing the deviation between the field pressure and the standard pressure by the standard pressure is 1% or less, the field pressure measured by the air pressure sensor is the reference pressure at the location of the street light. In case of exceeding 1%, the standard pressure obtained from the weather station is designated as the reference pressure, and the standard pressure of the predetermined number of weather stations adjacent to the streetlight is sorted in descending order to prepare a sample data set. If it corresponds to the value of the upper 70% or more of the sample data set, the air pressure around the street light is judged to be a high pressure zone, and at the same time, if the weather collected from the nearest weather station is clear, the weather is finally diagnosed as clear, If the reference air pressure falls below the lower 30% of the sample data set, around the street light At the same time, it is judged that the atmospheric pressure is low pressure, and at the same time, if the weather collected from the nearest weather station is cloudy or rainy and the humidity is more than 40%, it is finally determined that the weather is cloudy or likely to rain, and the weather information is analyzed. As a result, the current season is summer, the rainy season or typhoon is predicted, and if the humidity is more than 50% and the temperature is less than 25 degrees, it is finally determined that there is a high probability of rain, and as a result of analyzing the weather information, the current season is If it is winter, and if snowfall is predicted, it is finally diagnosed as having a high probability of snowing. When the weather is finally diagnosed in a clear state, the presence or absence of day and night is determined according to the measured value of the illuminance sensor, and the weather is cloudy. When the final diagnosis is made that there is a high probability of rain or snow, the lighting is controlled by judging both the measured value of the illuminance sensor and the sunrise time collected from the nearest weather station, and when the fog is detected, the brightness of the light is adjusted. Adjust 20% brighter than usual.
