Method and system for synchronously controlling multiple light-operated lamps

The invention relates to a method and system for synchronously controlling a plurality of light-operated lamps, and the method comprises the following steps: installing the plurality of light-operated lamps at corresponding positions, and fixing the position and orientation of a photosensitive sensor of each light-operated lamp; fixing a shielding object between each photosensitive sensor and outdoor light, so that the change coefficient of the outdoor light transmitted to each photosensitive sensor is fixed; when a plurality of light control lamps are set, the indoor brightness is adjusted to reach the target brightness of the light control lamps needing to be turned on, each light control lamp is driven to collect the current brightness through the photosensitive sensor, and each light control lamp stores the current brightness of the light control lamp as a brightness threshold value; when the plurality of light-operated lamps work, each light-operated lamp collects real-time brightness and compares the re
