A microwave motion detection system and lighting applications. Certain types of lighting devices turn on / off and may respond to certain triggers (e.g., motion-activation, dusk-to-dawn, etc.), etc. Such lighting devices may be battery powered and have minimal on-board circuitry. Coordinating these lighting devices together to provide zoned lighting functionality has not been commercially successful. Various aspects of the present disclosure are directed to “smart enough” lighting solutions. Smart enough lighting solutions may include link-based connectivity that enables coordination between peer lighting devices. The decentralized system may enable groups of smart enough lighting devices to communicate salient events (triggering conditions and operational parameters) across a mesh network, without centralized coordination. For example, each of the smart enough lighting devices may use point-to-point communication protocols to directly communicate with its peer devices, relaying information throughout the group.

The invention relates to the technical field of port illumination adjustment, in particular to a port storage yard dynamic dimming method fusing an astronomical algorithm and operation scene recognition, which comprises the following steps: constructing a background illumination model dynamically changing along with time; constructing a storage yard operation situation thermodynamic diagram; constructing a demand mapping rule base, and performing strategy matching on the mapping rule base and the job situation thermodynamic diagram; and constructing a lamp control model, and introducing multi-objective optimization calculation to generate a final control instruction. According to the port storage yard illumination multi-dimensional dynamic dimming method integrating the astronomical algorithm and the operation scene recognition, a cooperative control technology integrating the astronomical algorithm (time dimension) and the AI scene recognition (space dimension) is adopted, only low power is maintained in a storage yard operation area in the daytime, operation illumination is automatically improved to a high-activity area at night, energy conservation and safety are both considered, and the method is suitable for large-scale popularization and application. And a dual smoothing mechanism of smoothing in the morning and evening transition period and real-time dimming flicker prevention is designed, so that sudden brightness change or flicker is avoided, and the visual fatigue of operators is effectively reduced.
