摘要
LED作为新一代绿色光源,与传统光源相比,它具有光效高、寿命长、体积小、快速启动、易于调光等诸多优点,本文针对LED景观路灯实时控制的需求和现有控制策略存在的缺陷,提出了一种基于LED协议控制的景观路灯控制模型。首先分别从模糊处理器模块,数模转换模块,传感器采样电路模块以及控制对象模块构建控制系统,然后将光照强度和路面车流噪声经过线性变换后作为光照强度的期望值,并将其线性拟合转换为系统控制变量,再利用量化因子和比例因子对其优化来实现精确输入。通过仿真实验表明,本文提出的基于LED协议控制的景观路灯控制模型能实现实时环境变化下的LED路灯工作状态的控制,实现节能功能,实现动态的控制LED路灯的工作状态。
As a new generation of green LED light source, compared to traditional light sources, it has ahigh luminous efficiency, long life, small size, quick start, easy dimming and many other advantages, thispaper landscape LED lights real- time control of needs and existing control strategies exist defects,proposed landscape lights based on LED control protocol control model. Respectively, from the first fuzzyprocessor module, digital-analog converter module, sensor sampling circuit module and a control moduleobjects constructed control system, then the light intensity and road traffic noise after a lineartransformation as the light intensity of expectations, and to convert the linear fit system control variable,and then using the quantization factor and scaling factor for its optimization to achieve accurate input.Simulation results show that the proposed control protocol based on LED landscape lights control modelcan control the LED lights work to achieve real-time status of environmental change under, to achieveenergy-saving features, dynamic control LED lights working condition.
