Urban intelligent street lamp energy-saving control method and system based on LoRa technology

The invention relates to an urban smart street lamp energy-saving control method and system based on a LoRa technology, and the method comprises the steps: obtaining an image picture of each smart street lamp region in real time after a smart street lamp is turned on, and transmitting the image picture to a feature recognition model; the feature recognition model receives the image and judges whether a moving target exists in the current intelligent street lamp area or not; if the moving target does not exist in the preset duration, identifying a target dimming parameter matched with preset street lamp dimming in a database based on a preset dimming rule; if the target dimming parameter matched with the preset street lamp dimming is identified, acquiring a dimming execution instruction matched with the preset street lamp dimming; and sending the dimming execution instruction to the LoRa equipment terminal, so that the LoRa equipment terminal adjusts the brightness output value of the smart street lamp corresp
