Public place energy-saving lighting control system and method based on automatic perception

Abstract

The invention relates to a public place energy-saving lighting control system and method based on automatic perception. The system is composed of a plurality of distributed nodes. Each node comprises an information collecting module, a central processing module, a local lighting control module, an internode wireless communication module, a power state indication module and an awakening signal generation module, wherein the information collecting module is composed of a remote node working state monitoring and awakening module, an environment light perception sensor module, a lighting target detecting sensor module and a lighting target movement state perception sensor module. The system has a sleeping mode and a working mode, and energy consumption of the system is reduced. The on-off state of a lighting unit can be automatically controlled according to a detecting result, the intelligent degree is high, and the real-time performance is good. The system has the function of collaboration of adjacent nodes, and after the lighting target is detected, the system can detect whether the local brightness meets the requirement or not and whether the target moves or not and judge whether the adjacent nodes are informed to starting lighting or not according to the detecting result.

Description

technical field [0001] The invention belongs to the field of Internet of Things technology and lighting system automatic control, and relates to a public place energy-saving lighting control system and method based on automatic perception. Background technique [0002] At present, the lighting systems in public places such as school classrooms, office buildings, auditoriums, libraries, conference rooms, streets, and corridors have poor ability to automatically adapt to the real-time environment, and the level of intelligence is low, resulting in a huge waste of energy. In 2013, Su Shan, Ye Ting, etc. proposed a lighting system control method that adopts centralized control and management and decentralized execution in their paper "Research on Lighting Energy Saving Technology in Campus Public Places". The lighting areas are connected into a network through the bus, and the configuration The central monitoring center and the intelligent control lighting cabinet monitor and ma...

AI Technical Summary

Problems solved by technology

The system can only turn on the local lighting when the target is detected. Whether the lighting effect meets the requirements, whether to notify the adjacent nodes to start the lighting, etc. is not involved. The system is independent, has no collaborative function, low intelligence, and cannot achieve fine energy control. manage
