一种基于WiFi环境下的简易LED照明系统设计与实现

Design and implementation of a simple LED lighting system based on WiFi

随着国家对于节能减排政策的不断深入,LED照明代替传统的白炽灯照明已经成为了主流,而与此同时,无线通信技术的发展也使得其将各个单独节点的LED照明单元进行组网变为现实。为此,提出了一种基于网络环境下的LED照明系统,该系统以STC12C5202AD单片机为核心,通过WiFi模块ESP8266作为无线通信进行数据传输,从而实现了ULN2987芯片对于LED照明系统驱动及其控制。通过实验表明,在10m之内平均丢包率在2%以下,平均时间小于5ms,能够满足功能设计要求。

Along with the national energy conservation policy for the deepening of LED lighting to replace the traditional incandescent lighting has become mainstream, but at the same time the development of wireless communication technology makes the LED lighting unit individual nodes of the network into reality. To this end, proposes a LED lighting system based on the network environment, the system uses STC12C5202AD microcontroller as the core, through the WiFi wireless communication module ESP8266 as the data transmission, so as to achieve the ULN2987 chip for the LED lighting system and its control drive. The experimental results show that the average packet loss rate is less than 2%, the average time is less than 5 ms in 10 m, and to meet the functional design requirements.
