基于PL3106的室内调光控制系统

摘要

A indoor dimming control system based on PL3106 which is a low-voltage power line carrier communi-cation chip is designed for the character of inconvenience of indoor wiring and small noise. The system uses power line as transmission media,it can be easily designed and reduce the cost. The key of this design is to solve the effect of grid noise on communication,thus extending the communication distance. Taking PL3106 as the core hardware circuit of power line carrier communication, it can realize point to multipoint communication using the communication protocol, so that a plurality of lighting node can be controlled by the master controller. The test results show that, the system communication is stable in the 400 meters, it can accurately achieve dimming, and achieved good results.%针对室内布线不方便以及噪声干扰小的特点，设计了一种基于低压电力线载波通信芯片PL3106的室内调光控制系统。该系统以电力线为信息传输媒介，设计简单，节约成本。其关键要解决的电网噪声对通信的影响，从而延长通信距离。以PL3106为核心搭建了电力线载波通信的硬件电路，采用通信协议实现一对多通信，从而由总控制器控制多个照明节点。测试结果表明，该系统在400 m内通信稳定，能准确实现照明调光，取得了良好效果。
