Design And Development Of Wireless Lighting-Control Basedon NRF905 And Effect Showing

Lighting system is indispensable as an important part of buiding structure. In order to meet people's visual and aesthetic pursuit, the complexity and scale of the lighting system is developing in constantly. This leads a higher requirement about the control of lighting system. The traditional lighting-control systems rely on mechanical control by the decentralized switch and require lengthy cable, this leads to too much energy-consumption; also because the low level of integrated management, the manager can not handle the real-time situation about the site immediately in some large-scale place's lighting-control just like communities, parks and streets. Therefore, we need to develop an effective and centralized lighting-control system in the process of implementation of energy-saving and green lighting project, so as to achieve centralized lighting control about the lighting equipment of the buildings or premises, and show the effect of the scene.This thesis introduced the research of design and development about the wireless lighting-control and effect-showing system. In some small and medium size places like communities, streets, parks. Controlling the lighting equipments by using wireless way can not only be helpful with implementation and management, but also effectively for saving resources and reducing energy consumption in response to a national energy saving project. In process of lighting equipment management, there are many ways of handling the feedback of lighting system, such as LED marking...but they are lack of humanization, and making the management of on-site monitoring of lighting equipment not intuitive. The use of 3D(three-dimensional) visual way to give a live feedback to manager can greatly improve the humanized operation.First, this thesis introduced the working principle of NRF905, which is a radio frequency communications chip, as well as the working principle of the relay, then combined the STC89C52 chip microcontroller with integrated RF communication chip NRF905 to build wireless transmitter and receiver; and then introduced the principle and using of FDMA;On this basis, this thesis analyzed the principle of the serial communication and using.Net serial communication technology to construct the communication link of the hardware. Second, this thesis analyzed the principle of methods to build 3D scene on.Net environments with XNA Framework, with the principle of Shader rendering technology, this thesis showed the lighting effects of the scene of an indoor sports stadium as an example with Shader, using point source as a light source selection type of lighting for the effect showing. In addition, this thesis made the equipment of wireless communication and 3D scene in XNA.
