Light operation method and system for smart city

The invention relates to a light operation method and system for a smart city, which belong to the technical field of city lighting management. The method is applied to centralized management equipment and branch management equipment, time periods are preset in the centralized management equipment, and each time period comprises a power consumption period and a non-power consumption period. The method comprises the steps that flow data sent by each piece of branch management equipment in a power utilization period are received, the flow data comprise pedestrian flow, vehicle flow and time distribution information, and the time distribution information comprises the passing time, captured by a monitoring camera, of each pedestrian or vehicle; the pedestrian flow and the vehicle flow are integrated to generate a passing flow value; if the past flow value is smaller than a preset flow threshold value, a plurality of non-power-consumption time regions are generated according to a plurality of pieces of historical
