作为有线通信的补充和发展,无线通信系统自20世纪,特别是21世纪初以来得到了迅猛的发展。无线通信系统开始进入千家万户,其应用使人们的生活进入信息化智能化阶段。同时,新兴的发光二极管(LED,Light Emitting Diode)照明因其低耗能及环保的特点,正在逐步取代传统照明。这里将无线控制以及自组网技术引入家庭LED照明系统当中,设计了基于433 MHz无线通信网络的LED调光控制系统模型,同时对方案中的关键性技术进行分析和研究。
As a complement and development of wired communication, the wireless communication system has developed rapidly since the 20th century, especially from the beginning of the 21st century. The wireless communication system begins to enter every household, its application makes the life of people enter the intellectualized stage of informationization. At the same time, emerging LED (Light Emitting Diode) lighting is gradually replacing traditional lighting due to its low power consumption and environmental friendliness. Here we introduce wireless control and ad hoc networking technology into the home LED lighting system, and design a LED dimming control system model based on the 433 MHz wireless communication network. At the same time, the key technologies in the program are analyzed and researched.
