【摘要】：伴随着电子信息技术的高速发展以及移动互联网的快速普及，现代人的生活品质得到了明显的提高，人们对于智慧家居的需求越来越强烈，将家电、照明灯具、家庭影院、安全系统等模块通过无线或有线网络的方式集成到终端控制系统中，实现家居的智能管理和控制已经成为当今消费类电子的发展方向。智能家居的概念也逐渐从抽象变为具体，进入21世纪，智能家居的发展呈现多样化，技术实现方式也更加的丰富，依托物联网技术发展的智能家居更是越来越成为热点。 智能照明系统是智能家居中必不可少的重要组成部分，传统的照明系统由于布局布线复杂，，功能简单，色彩显示单一，已经无法满足人们日益提高的照明品质要求，本文在传统照明系统的基础上进行了改进，对新一代智能照明系统进行了研究和设计，照明光源选用第四代绿色光源LED，硬件驱动采用256级PWM驱动方式，控制方式采用2.4G ZigBee无线和TCP/IP网络通信，交互设计采用Android智能手机平台，实现了“智能手持终端集中控制，网关模块数据透传，LED灯具实时响应”的设计目标，提供给用户智能化、无线化、网络化的全新的照明体验。 本论文的主要研究成果有： 1、设计制作了无线化、网络化和宽色域的新一代照明光源节点，硬件设计选用WRGB四色LED灯珠，通过PWM调波的方式进行控制，软件设计通过设计优化的xyY2RGB色度空间转换算法及相应的驱动代码，实现了高达1600万色的精准色域选择和细腻柔和的色彩表现，提供用户极佳的照明体验。 2、设计了自适应网关和远程WEB服务器，网关自动进行ZigBee协议和TCP/IP协议转化，WEB使本灯控系统具有远程访问功能，软件架构设计具有可扩展性，能够在此基础上进行例如智能插排等物联网智能家居设备的开发。 3、控制方式采用Android智能手机平台，摒弃了传统的控制平台多选用PC或者需单独设计对应的遥控器的方式，极大的提高了系统的实际应用价值。 4、设计了一套较为完整的智能灯控系统通信协议，能够调节LED灯的颜色、亮度、饱和度，设置延迟开/关灯，对灯进行分组控制，预置情景模式，选择远程访问模式。该通信协议能够较好的覆盖智能照明领域所需的所有功能，协议接口简单，可移植性强，具有较好的推广性。
[Abstract]:With the rapid development of electronic and information technology and the rapid popularization of mobile Internet, the quality of life of modern people has been significantly improved, and the demand for intelligent home is becoming stronger and stronger. Security system and other modules are integrated into terminal control system by means of wireless or wired network. It has become the development direction of consumer electronics to realize intelligent management and control of home. The concept of smart home has gradually changed from abstract to concrete. In the 21st century, the development of smart home is diversified, and the realization of technology is more and more rich. The smart home based on the Internet of things technology is becoming more and more hot. Intelligent lighting system is an essential part of smart home. Because of complex layout and wiring, simple function and single color display, the traditional lighting system can not meet people's increasing lighting quality requirements. In this paper, the traditional lighting system is improved, and the new generation intelligent lighting system is researched and designed. The fourth generation green light source LED, hardware driver is used to drive the fourth generation green light source, and 256grade PWM driver mode is adopted. The control mode adopts 2.4G ZigBee wireless and TCP/IP network communication, and the interactive design adopts Android smartphone platform. The design goal of "centralized control of smart handheld terminal, data transmission of gateway module and real-time response of LED lamps and lanterns" is realized. Provide users with intelligent, wireless, network-based new lighting experience. The main research achievements of this thesis are as follows: 1. A new generation of lighting source node with wireless, networked and wide color gamut is designed and manufactured. The hardware design adopts WRB four-color LED lamp bead, which is controlled by PWM wave modulation, and the main research results of this thesis are as follows: 1. By designing the optimized xyY2RGB chromaticity space conversion algorithm and the corresponding driving code, the software design realizes the accurate color gamut selection of up to 16 million colors and the delicate and soft color performance, and provides excellent lighting experience for users. 2. The adaptive gateway and remote WEB server are designed. The gateway automatically converts ZigBee protocol and TCP/IP protocol. WEB makes the lamp control system have remote access function, and the software architecture design has extensibility. On this basis, such as intelligent plug-in and other things intelligent home equipment development. 3, the control mode adopts the Android smart phone platform, abandons the traditional control platform to choose the PC more or need to design the corresponding remote control separately, which greatly improves the practical application value of the system. 4. A set of communication protocol of intelligent lamp control system is designed, which can adjust the color, brightness and saturation of LED lamp, set the delayed on / off light, group the lamp, set the scene mode, and choose the remote access mode. The communication protocol can cover all the functions needed in the intelligent lighting field. The protocol has the advantages of simple interface, strong portability and good generalization.
