摘　　要：电子技术的发展给我们的生活带来了巨大的改变,传统的水都是由下向上运动的喷泉景观已难以满足人们的审美需求。本课题设计出了一个能够使人在视觉上出现水滴上升、静止、下降3种不同状态的珍珠喷泉景观的控制系统。该控制系统包括LED灯组、LED驱动电路和滴水装置。LED驱动电路控制LED灯的闪烁频率,当不同闪烁频率的灯光照射在恒定下落频率的水滴上时,水滴在空中就会像珍珠一样呈现出上升、静止和下降3种不同的视觉景象。实验结果表明,该控制系统稳定可靠、成本较低,能满足人们的需求。The lifestyle of people has the huge change with the development of electronic technology. The traditional fountain landscape that water moves from up to down doesn＇t meet the demand of people. The control system based on pearl fountain landscape that can produce three different kinds of sightseeing, such as up, static and down of water-drop is designed. The control system consists of LED, the drive circuit of LED and the drip device. The lighting frequency is controlled by the drive circuit of LED. Water-drop that is like pearl can produce three different kinds of sightseeing by the changing lighting frequency of LED and the constant falling frequency of the water-drop. The result shows that the control system is reliable, low cost and is able to meet the demand of people.
