基于Zig Bee技术的智能调光开关设计

根据智能家居的发展方向和用户需求,设计了一种基于Zig Bee技术的智能调光开关系统。设计方案采用新一代SOC芯片CC2530作为系统的无线收发模块,使得模块具备成本低、功耗小、高可靠、自组网、超视距通信等能力。采用ARM7嵌入式处理器LPC2132作为系统的微控制器模块,简化设计提高可靠性,使得系统具备分布处理能力。通过检测市电的过零点,开启延时定时器,定时器超时后触发双向可控硅导通的时间点来达到调光的目的。结果表明:本设计能够使家居照明系统更具可控性,更节能,使得家居环境更加舒适。

Design of smart lighting switch based on Zig Bee technology

According to development direction and users＇ demand of smart home, a smart lighting switch system based on Zig Bee technology is designed. Design scheme adopts a new generation of SOC chip CC2530 used in the wireless receiver and transmitter module, and it makes the module has the functions of low cost, low power dissipation,high reliability, Ad Hoc network, horizon communication. At the same time, the ARM7 embedded processor LPC2132 is used as the system＇ s microcontroller module, owing to it, the design is simpler and more reliable, and it let the system has the ability, of distributed processing. After measuring the zero crossing point of city power,the delay timer is set,and the turn-on time of TRIAC can achieve the aim of light control. The results indicate that ,this design let the home lighting system be more controllability, save more energy, make the home environment more comfortable.
