| 摘 要： | 针对传统的LED景观灯控制系统控制灯数量少、无法实现柔和渐变效果等问题,提出了一种多参数可编程的LED景观灯控制系统,基于CPLD设计了控制系统的控制盒;根据实际情况设定了场景数据的传输协议,并用QuartusII软件进行了功能仿真.仿真结果表明:该系统可实现不同地址的LED景观灯在256级灰度调制范围内以不同的速度变化等级达到预设的亮度级别,并输出红、绿、蓝三基色相应的PWM占空比信号,最终实现景观灯柔和渐变的效果.

| Abstract: | Aiming at the existing problems of traditional LED landscape lamps which the number of lamps controlled is less,and the effect of soft change can not be achieved,a multi-parameter programmable control system of LED landscape lamp is proposed.In the control system,the control box is designed based on complex programmable logic device(CPLD).According to the actual situation,the scene data transfer protocol is set,function and timing simulation is done to the control system using QuartusII software.The results show that the system can control different address LED lamps to reach the present light intensity gray value in a certain rate,and the brightness is changed in the range of 256 level gray modulation.Finally,the corresponding PWM control signals of red,green and blue tricolor are output,to reach the effect of soft change. |
