Scheme Design And Implement Of Indoor Intelligent Lighting System

Currently, the energy shortage and environmental pollution cause worldwide attention, as the main body of the energy consumption, lighting urgently needs to implement environmental protection and energy-saving. With the continuous development of technology, especially the development of semiconductor technology, communications network technology and intelligent control technology, intelligent lighting has laid a solid foundation for its realization. With the continuous improvement of living standard, people’s demand for lighting has changed, "smart, energy-saving, comfortable, efficient, safe" become the major feature of the new generation of lighting.This thesis is based on Zig Bee wireless communication network, and using TCP / IP protocol, complete the design and implementation of intelligent lighting system which is based on Android operating system and provides a variety of lighting functions, and the scene lighting has been studied to provide illumination mode solution. The main works of this thesis include:(1) Overal design. Through investigating the research status and overall development of intelligent lighting, make a comprehensive need analysis for system design and mobile control terminal software design, achieve overall architecture design of indoor intelligent lighting system, and complete to build hardware of system and the design of functions for mobile control terminal. Functions conclude: configuration of the server, generation and management of room, search and configuration of lighting, management and operation of single lamp, management and control of model, total household switch and a variety of additional functions(include alarm reminder, simulated sunrise, aid sleep, schedule task) and so on.(2) Software implementation of mobile control terminal. Based on overal design, complete the design of the overall framework for software; based on Zig Bee, TCP/IP protocol and Socket communication, complete realization of the network communication module, include data protocol, configuration protocol, control protocol, response protocol, and so on; based on SQLite database of Android, complete realization of the database module, store information of lamps, rooms and lighting mode effectively; based on Android application framework and JAVA code, complete realization of multiple modules interface design and functions.(3) Design and analysis of scene lighting model. By studying the scene lighting, define different lighting modes in multiple scenarios, put forward scene lighting model creatively, and then make analysis and calculation of the model for scene lighting with optical knowledge, geometry of model and optimization method for solving, and provide scientific solutions for illumination modes of systemAfter testing, the overall situation of the system that this thesis designs is well. Multiple lighting functions of system operate properly; after repeated testing, the subordinate computer supports long-time stability work, data sending and receiving are normal between modules, and communication stability of system is effectively guaranteed; system performance is good, software occupies less memory resource of the mobile terminal and it is adapted to a variety of mobile terminal and LED driver has high efficiency, and so on.
