Zigbee And Arm Technology-Based Intelligent Building Lighting System

With the development of science and technology and the improvement of people’s living standard, people proposed new requirements for architectural lighting system, such as intelligent controlling, energy-saving, which gave rise to the intelligent light-ing industry. Plus the new lighting technology (such as LED and CCFL lamp) getting matures, intelligent lighting made great development.Intelligent lighting are classified to the part of the smart home system by most of the industries, so much more research on building lighting is needed. At the same time, intelligent building lighting is a relatively new concept. The old lighting standard is not suitable for the new requirements. There is a lack of unified standard within the building lighting industry. Moreover, given the constraints of sensor technology and lighting technology, as well as the theoretical limitations of visual comfort, most of the existing smart lighting only had the function of brightness adjustment and model switching, which can not fully meet the demand of heathy and green lighting environment.This paper analyzed the features of the building lighting system, containing the characteristic that no body is responsible for the lighting of public places, and there are a huge number of the buildings lighting equipment and sensor devices. On the other hand, we analyzed the needs of the people, for example the needs of lighting-chroma, illumination and the requirement of a better use of natural light. After that, we designed a green, healthy and energy-saving method of building lighting controlling. We realized a complete set of intelligent building lighting system, the system was divided into three parts, they are processing core, communication network and controlling terminals. We adopted embedded linux system development technology to achieve the function of the processing core. We also used the Zigbee network technology to build a communication network. At last we used the GUI programming techniques to achieve the controlling terminal. Finally, on hardware, we designed the ARM processing core, the Zigbee network nodes and the controlling terminals, and designed the PCB by Altium Designer.We realized the intelligent building lighting system prototype.In the first chapter the paper introduced the development status and significance of intelligent building lighting system. The second chapter described the theoretical preparation of the system design. The third chapter described the design of intelligent building lighting system specifically, from the overall structure of the system to the design method of the individual modules. The fourth Chapter introduced the. realization of the system, containing the ARM processing core, Zigbee network nods and user controlling terminals, and gave a demonstration network and each module’s hardware prototype. Finally, we made a summary and outlook about the system.
