【摘要】：现如今,环境保护的观念深入人心,节能和减排成了全社会的共识。照明工具是人们生活中必不可少的部分,它实现绿色照明对减低能耗,建设节约型社会有重要意义。LED作为一种绿色光源,具有能耗低、体积小、寿命长等优点,是照明的理想光源。以LED为核心的照明技术与无线控制技术相融合的智能照明技术,是实现照明控制系统“网络化、智能化、标准化”的关键。在无线通信技术中,ZigBee技术因其低功耗、成本低、网络容量大、自组网等特性,在生活中有广泛的应用,它可以将分布在家中含有ZigBee节点的设备,通过ZigBee网络连接起来。同时结合Wifi技术有高速率、能够直接联网的特点,可以将照明系统与家庭外网相连,实现各种智能控制端对智能照明系统的控制。优秀的智能照明系统可以提高人们的工作效率,提升生活环境的品质。本论文将主要从两方面对智能照明系统进行研究:设计适合本系统的高品质光源和设计方便管理的智能化控制管理系统。具体工作内容:首先分析了智能照明的发展状况,学习相关知识,给出了ZigBee-Wifi网关+ZigBee智能灯具+智能用户端的设计方案;针对智能灯具的特点,设计了一款RGB灯珠并对传统衬底进行结构改造;针对灯具色温、亮度的调节提出了一种新的获取灰度值的方法;然后对ZigBee-Wifi网关和ZigBee智能灯具进行硬件设计和实物制作;接着基于Z-Stack协议栈在IAR平台进行了具体的嵌入式软件设计,实现了组网通信,调光控制等功能;最后主要针对PC端用Qt Creator进行监控软件的设计。将系统进行联合调试组网成功后,用户使用智能控制端实现了对系统有效的控制;自动模式、手动模式运行正常;色温、亮度、颜色都能独立可调;色温—温度补偿照明、恒照度照明达到预期效果。
[Abstract]:Nowadays, the concept of environmental protection is deeply rooted in the hearts of the people, energy conservation and emission reduction has become the consensus of the whole society. Lighting tool is an indispensable part of people's life. It realizes green lighting to reduce energy consumption and build energy-saving society. As a green light source, LED has the advantages of low energy consumption, small size, long life, etc. It is an ideal light source for lighting. The intelligent lighting technology, which is based on LED and wireless control technology, is the key to realize the "network, intelligence and standardization" of lighting control system. ZigBee technology has been widely used in wireless communication due to its low power consumption, low cost, large network capacity, ad hoc network and so on. It can connect devices with ZigBee nodes in their homes through ZigBee network. At the same time, the Wifi technology has the characteristics of high speed and can be connected directly to the home external network, which can realize the control of intelligent lighting system at various intelligent control ends. Excellent intelligent lighting system can improve people's working efficiency and improve the quality of living environment. This paper mainly studies the intelligent lighting system from two aspects: designing the high quality light source suitable for the system and designing the intelligent control management system which is convenient for management. Specific work content: first of all, it analyzes the development of intelligent lighting, studies the relevant knowledge, and gives the design scheme of ZigBee-Wifi gateway ZigBee intelligent lamp intelligent user, aiming at the characteristics of intelligent lamps, A RGB lamp bead is designed and the structure of the traditional substrate is modified. A new method to obtain gray value is proposed for the adjustment of the luminaire color temperature and luminance. Then the hardware design and physical production of the ZigBee-Wifi gateway and the ZigBee intelligent lamp are carried out. Then the embedded software is designed on the IAR platform based on Z-Stack protocol stack. The functions of network communication and dimming control are realized. Finally, the monitoring software based on QT Creator is designed for PC. After the system was successfully debugged and set up successfully, the user realized the effective control of the system by using the intelligent control terminal; the automatic mode and the manual mode operated normally; the color temperature, brightness and color could be adjusted independently; the color temperature and temperature compensation lighting, Constant illumination illuminates to achieve the desired effect.
