摘要：隨著人們生活水平的提高和建立綠色城市的向往，音樂噴泉以其獨(dú)特的魅力和特殊的功能，愈來愈成為休閑娛樂產(chǎn)業(yè)中的一項(xiàng)重要的產(chǎn)品，音樂噴泉的興建也越來越多了。本文結(jié)合目前國內(nèi)音樂噴泉的發(fā)展現(xiàn)狀，即大型音樂噴泉技術(shù)發(fā)展成熟，而小型音樂噴泉仍處于起步狀態(tài)。創(chuàng)新地把小型音樂噴泉引入家庭，設(shè)計出實(shí)惠的單片機(jī)控制系統(tǒng)，成功地把大型音樂噴泉小型化，把室外大型音樂噴泉搬到室內(nèi)具有前瞻性的現(xiàn)實(shí)意義。而本系統(tǒng)成功地改用單片機(jī)程序及其控制電路調(diào)節(jié)潛水泵轉(zhuǎn)速，降低了成本。 根據(jù)目前音樂噴泉的發(fā)展現(xiàn)狀，本設(shè)計介紹一個以AT89S52單片機(jī)為核心，用C語言對其進(jìn)行編程實(shí)現(xiàn)的小型音樂噴泉控制系統(tǒng)。設(shè)計出了一種控制簡單，成本較低且易于推廣使用小型音樂噴泉的控制系統(tǒng)。系統(tǒng)原理：用單片機(jī)根據(jù)音樂的強(qiáng)弱對電機(jī)的轉(zhuǎn)速進(jìn)行控制，以便控制噴泉水柱的高低。輸入為音樂成正比的電壓信號，輸出為對水泵轉(zhuǎn)速的控制量。給出了主程序框圖和程序。從而使噴泉水姿隨音樂節(jié)奏而變化。 關(guān)鍵詞：音樂噴泉；單片機(jī)；控制系統(tǒng)
ABSTRACT：As people 's living standards improved and the establishment of the yearning of the green city , a musical fountain with its unique charm and special features increasingly becomes an important product in the entertainment industry , the construction of the musical fountain is also increasing . In this paper, the current development status of the domestic musical fountain is that large - scale musical fountain technology is mature , and small musical fountain is still in its initial state .Letting small musical fountain Innovatively into the family, to design a cost-effective single chip control system to the miniaturization of large-scale musical fountain , moving the large outdoor musical fountain to the indoor has practical significance and forward-looking . The system switched to the SCM process and control circuit to adjust the submersible pump speed to low cost . Based on the current development status of the musical fountain , the design introduced a AT89S52 MCU as the core , using the C language programming to achieve a small musical fountain control system . Devised a small-scale musical fountain control system can be simplely controled, low cost and easy to promote the useness. The system works: the strength of the music with a microcontroller according to the motor speed control, in order to control the level of the fountain water column . Input music directly proportional to the voltage signal , the output is the amount of control of pump speed . The main program block diagram and procedures were given . So that the water fountain posture change with the rhythm of the music . Key words: Musical Fountain; Microcontroller; SCM
