音乐喷泉控制器的设计 (硬件设计) 单 位: 二十五队二中队 专 业: 电子信息工程 姓 名: 指导教师: 完成年月: 2009 年6月4日 摘要： 音乐喷泉控制器是音乐喷泉的核心部分。在音乐喷泉中，喷头的多姿造型和缤纷的水下灯光都受喷泉控制器的控制。由于不同的喷泉对水泵和彩灯组数的要求各不相同，因此可以设计一种简单、通用、组数可灵活扩充的喷泉控制器。本喷泉控制器采用全数字集成电路设计，可以灵活改变水泵和彩灯的组数。 本设计分为音控、程控两用的音乐喷泉控制器。控制三组不同颜色的彩灯，五台不同喷泉造型的水泵。音控、程控可用开关手动切换。程控的速度可用电位器调节。音控时，输入音乐的音量直接控制彩灯，音乐音量小则彩灯打开的组数少，音量大则彩灯打开的组数多，在音乐音量较长时间不变时，彩灯打开的组数不变，但各组应能循环打开，以避免灯光和造型的单调。 设计中主要用到的方法，音乐经过峰值检波后，得到和音量大小相关的控制电压，将此控制电压，经过简单的A/D转换变成数字信号后，去控制存储器芯片的高位地址，同时程控地址发生器也发出控制存储器芯片的地址信号，这两组地址信号经地址切换开关选择后去控制存储器的地址，该存储器地址对应的数据信号就会输出，输出信号经隔离驱动后就去推动彩灯工作。 关键字：峰值检波、A/D转换、EEPROM（AT28C64B）、程控地址发生器（CD4060） Abstract： The musical fountain controller is the musical fountain heart. In the musical fountain, the nozzle varied modeling and the riotous submarine light all receive the eruptive fountain controller the control. Is various as a result of the different eruptive fountain to the water pump and the color lamp bank number request, therefore designs the eruptive fountain controller which one kind simple, general, the group number may expand nimbly to become an eruptive fountain designers topic. This eruptive fountain controller uses the entire digital circuit design, may change the water pump and the colored lantern group number nimbly. This design divides into the sound to control, the program control dual purpose musical fountain controller. Controls three groups of different colors the colored lanterns, five different eruptive fountain modeling water pump. The sound controls, the program control available switch silk thread business manual cut. Program control peed available potentiometer adjustment. then the volume the colored lantern opens greatly the group number are many, when music volume long time invariable, the colored lantern opens the group number is invariable, but each group ought to be able to circulate opens, avoids the light and modeling monotonous. In the design mainly uses the method, music after the peak detection, obtains with the volume size correlation
