基于CPLD的LED景观灯智能控制系统
Intelligent control system of LED landscape lamp based on CPLD
摘要
Abstract
Aiming at the. existing problems of traditional LKD landscape lamps which the number of lamps controlledis less, and the- effect of soft change can not be achieved, a multi-parameter programmable control system of LED landscape lamp is proposer!. 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 LKD 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 outpul, to reach the effect of soft change.关键词
