[0069] When the comprehensive data analysis unit generates any two or more of the light-on signal 1, light-on signal 2 or light-on signal 3, a total light-on signal is generated;

The intelligent street light control unit controls the street light to turn on according to the total on signal, and controls the street light to turn off according to the total off signal.

[0072] By calculating the growth rate of intersection traffic, the increase or decrease of light intensity and the average humidity, it is determined whether the corresponding values ​​exceed the corresponding thresholds. Therefore, according to the changes in light intensity, ambient humidity and intersection traffic, it is determined whether the street lights need to be turned on in the current situation. In this way, the street lights can be reasonably adjusted according to weather changes and traffic flow changes to avoid energy waste and increase light pollution. At the same time, the street lights can be turned on according to weather changes to avoid setting a time to turn on or off the street lights, so that the street lights can be automatically turned on when needed.
