The meteorological data analysis unit 110 receives and analyzes meteorological data from the meteorological data providing system 1 . Here, the meteorological data providing system 1 may be, for example, a system for providing meteorological data of each country's meteorological offices, and the meteorological data provided from the meteorological offices include the minimum temperature, maximum temperature, precipitation and Various meteorological data necessary for predicting the amount of power generation of solar cells, including cloudiness, may be applicable.

The insolation prediction unit 120 predicts future solar radiation by using a deep learning algorithm from the weather data analyzed by the weather data analysis unit 110 .

The amount of power generation prediction unit 130 predicts the amount of power generation of the solar cell 310 provided in the street lamp system 300 using a deep learning algorithm from the amount of insolation predicted by the insolation prediction unit 120 .

Referring to FIG. 4 , the solar radiation prediction unit 120 and the generation amount prediction unit 130 are deep learning for predicting solar power generation, and deep learning is configured as a deep neural network (DNN) that can be predicted only with each daily input pattern. Deep learning that predicts the amount of insolation using the temperature, precipitation, cloudiness data, etc. provided in real time by the weather data providing system 1, for example, the Meteorological Agency system, and predicts the next day's solar power generation using the predicted insolation model can be constructed. In addition, the insolation predicting unit 120 and the power generation predicting unit 130 may generate and configure the respective models for performing the short-term daily generation amount prediction for the generation amount prediction through the insolation amount prediction result. This will be described in more detail as follows.

The characteristics of raw data are six of the current month, day, hour, temperature, precipitation, and insolation, among which month, day, hour, rainfall. The four can be used as they are, and since temperature and solar radiation are affected by the passage of time, more than 70,000 historical data of a certain section can be used together.

The lighting control unit 140 outputs a control signal for adjusting the brightness of the lighting of the street lamp system 300 according to the amount of generation predicted by the generation amount prediction unit 130 . The lighting control unit 140 is the first stage of brightness control through estimating the battery SOC, and the brightness when the number of consecutive days of outage that the battery 320 of the street lamp system 300 can withstand is within 1 day, that is, when the battery SOC is within 30%. The battery SOC is maintained through reduction, and when the battery SOC is more than 70%, the maximum brightness can be determined regardless of the predicted generation amount of the second stage.

Referring to FIG. 2 , the lighting control unit 140 estimates that the battery 320 of the street light system 300 is charged at the first setting time, for example, until 6 pm, and then at the second setting time, for example at 8 pm. The brightness of the lighting unit 320 of the street lamp system 300 is primarily determined according to the SOC (State Of Charge) of the battery 320, and the load on the lighting unit 320 is turned on ( on), after that, the brightness of the lighting unit 320 is secondarily adjusted according to the amount of power generation predicted by the generation amount prediction unit 130 at the third setting time, for example, at 1 am, after the first set time, for example, 5 hours have elapsed. By determining, the load on the lighting unit 320 is corrected to have the secondly determined brightness, and after that, the second set time, for example, 3 hours have elapsed and the fourth set time, for example, at 4 am, the load of the lighting unit 320 . can be controlled to turn off (off).

The lighting control unit 140 receives the battery SOC estimation data provided from the state monitoring unit 344 to be described later in the street light system 300 through the bidirectional blinking gateway 200, and receives the battery 320 of the street light system 300 . ) can be used as SOC for That is, the state monitoring unit 344 actually measures the battery SOC state at the start of one day's power generation and at the end of one day's power generation for each street lamp in the street light system 300 , and transmits it to the central control system 100 . In addition, the state monitoring unit 344 may transmit whether the street lamp system 300 is faulty or the like to the central control system 100 through the state transfer unit 250 of the bidirectional blinking gateway 200 .

Wow

can be calculated as the energy that the battery 320 has at the time of measurement.

The remaining amount of the battery 320 on the day becomes a factor that can determine the brightness of the lighting unit 330 for the next day.

Since the voltage is rapidly reduced at a point below the battery SOC of 20%, the usable SOC range of the battery 320 may be set to 100% to 20%. By using the generation amount prediction and the estimated battery SOC, the energy of the battery 320 provided in the street light system 300 of photovoltaic power generation can be minimized and operated stably, for example, in two stages at 8:00 PM and 1:00 AM. By dividing, the brightness of the load of the lighting unit 330 may be changed. Here, in the first step, the brightness may be adjusted by estimating the amount of generation of tomorrow, and in the second step, the brightness may be adjusted by determining the battery SOC.

Referring to FIG. 3, when the load of the lighting unit 320 by the lighting control unit 140 is described in detail, the lighting control unit 140 estimates the battery SOC (S11), and the battery SOC is the first set value ( X1), for example, if it is 0.7 or more, maximize the brightness of the lighting unit 320 of the street light system 300 (S12), and if the battery SOC is less than the first set value (X1), for example, 0.7, by estimating the battery SOC again ( S13), if the battery SOC is less than the second set value (X2), for example, 0.4, the brightness of the lighting unit 320 is minimized (S14), and if the battery SOC is the second set value (X2), for example, 0.4 or more, the amount of power generation The weather is checked by the prediction unit 130 (S15), the predicted power generation amount of the solar cell 310 is predicted in the street light system 300 (S16), and the battery total SOC (E total) is the sum of the predicted power generation amount and the battery SOC ) is obtained (S17), and when the battery total SOC (E total) is the third set value (X3), for example, 0.7 or more, the brightness of the lighting unit 330 is maximized (S12), and the battery total SOC (E total) is If the third set value X3, for example, is less than 0.7, the brightness of the lighting unit 330 is adjusted to decrease at a predetermined rate (S19). Here, the first to third set values X1, X2, and X3 may mean a ratio of the battery SOC to the maximum storage amount of the battery.
