用MCS51单片机制作的音乐喷泉控制器

Spring With Music Controller Made of Single Chip Microcomputer MCS51

介绍一种音乐喷泉控制器的原理、系统硬件及其应用软件。它的原理是预先将喷泉控制的数字信号调制后与乐曲同步录制记录在磁带上 ,播放乐曲同时由单片机解调出控制信号经功率放大驱动潜水泵及灯光系统 ,从而使喷泉水姿 ,灯光色彩随音乐节奏而变化。

The paper presents a controller which is used in a spring with music. We also describe its operative principle of system structure, hardware and applied software. Its principle is that using pretreated digital signals which is synchronizedly recorded with music by tape, the signal is demodulated by MCU to control the pumps and lamps so that the spring form is changed with music′s rhythm when music is played. This system is applied at Jiangsu Science Palace.
