The invention provides the music fountain device, which has the advantages of small volume, convenience in installation and capability of being ejected synchronously with the music, comprises the 89C51 single chip microcomputer, a volume unit (VU) signal circuit, an analog/digital (A/D) switching circuit, a motor drive mechanism, a motor and a fountain actuating mechanism, and has the structural key points that: a fractional frequency section is directly connected with a music source to process the music source; a VU signal conversion device is respectively connected with the fractional frequency section and the A/D switching circuit, a signal which is sent out by the fractional frequency section is converted into a VU signal, and the VU signal is sent to the A/D switching circuit; the A/D switching circuit is respectively connected with the VU signal conversion device and the single chip microcomputer, and the VU signal is converted into a digital signal to be sent to the single chip microcomputer for processing; and the single chip microcomputer adopts a 51-series single chip microcomputer, an output end is connected with an interface circuit 8255A, and the rotation of a motor is controlled through a drive circuit.
Description
Technical field:
The present invention relates to a kind of music fountain device, relate to a kind of music fountain control device in particular based on the 89C51 single-chip microcomputer.
Background technology:
Fountain constantly appears at square, park and other public places in city as the higher artistic water scenery of a kind of sight.Along with growth in the living standard, people are increasingly high to environmental requirement, and urban environmental protection is paid attention to by people day by day.Near the curbside in city and some buildings, the humidity that fountain apparatus not only can increase surrounding air is set, reduces airborne dust, reduce air themperature, more people's life has increased many temperament and interest.The sculpture on various fountain and square, gardens just quietly rises in the city, has not only enriched the view of city trees and shrubs, and has strengthened the appeal in city, has beautified The Surroundings in Cities, has enriched people's life.The exploitation of music fountain has very big development prospect with research, and external at present technology of the same trade is embodying the extensive use of high-tech technology in show business invariably, and the research of domestic this respect is also just progressively carried out.Yet the spray regime of most of fountains all is fix nonadjustable, and some dullness seems; The fountain that many combining musics also occurred simultaneously, but these all are that music and fountain are simply made up mostly can't really reach the degree that the spray regime of rhythm and the melody and the fountain of music is carried out synchronously.Present this field; To can debugging and can urgent demand be arranged with the synchronous water spray control device of music rhythm, and this control device should satisfy volume as far as possible little, easy for installation, can farthest control this several kinds of requirements to spray regime.
Summary of the invention:
The present invention is exactly to the problems referred to above, and the music fountain device that a kind of volume is little, easy for installation, can spray synchronously with music is provided.
For realizing above-mentioned purpose; The present invention adopts following technical scheme; The present invention includes 89C51 single-chip microcomputer, VU signal circuit, A/D change-over circuit, motor-driven mechanism, motor and fountain actuator, its structural feature frequency-division section directly is connected with music source, and music source is handled; The VU chromacoder is connected with the A/D change-over circuit with frequency-division section respectively, and the conversion of signals that frequency-division section is seen off is the VU signal, and delivers to the A/D change-over circuit to the VU signal; The A/D change-over circuit is connected with single-chip microcomputer with the VU chromacoder respectively, is the VU conversion of signals that digital signal is given single-chip microcomputer and handled; Single-chip microcomputer adopts 51 series monolithics, and output is connected with interface circuit 8255A, and controls the rotation of motor through drive circuit.
Beneficial effect of the present invention:
Owing to the present invention includes 89C51 single-chip microcomputer, VU signal circuit, A/D change-over circuit, motor-driven mechanism, motor and fountain actuator, frequency-division section directly is connected with music source, and music source is handled; The VU chromacoder is connected with the A/D change-over circuit with frequency-division section respectively, and the conversion of signals that frequency-division section is seen off is the VU signal, and delivers to the A/D change-over circuit to the VU signal; The A/D change-over circuit is connected with single-chip microcomputer with the VU chromacoder respectively, is the VU conversion of signals that digital signal is given single-chip microcomputer and handled; Single-chip microcomputer adopts 51 series monolithics, and output is connected with interface circuit 8255A, and controls the rotation of motor through drive circuit.Therefore, the present invention can not only can control the spray regime of fountain, and can make the injection of fountain and music synchronous; The volume of device is little, and it is also convenient to install, and has reached social now requirement of fountain being sprayed control.
Description of drawings:
Fig. 1 is a general structure sketch map of the present invention;
Fig. 2 is a VU signal circuit diagram of the present invention.
Embodiment:
The present invention includes 89C51 single-chip microcomputer, VU signal circuit, A/D change-over circuit, motor-driven mechanism, motor and fountain actuator; Frequency-division section directly is connected with music source, and music source is handled, and reaches the purpose of picking up music more information amount, improves the control effect and also can realize fountain is controlled by various spray types combinations; The VU chromacoder is connected with the A/D change-over circuit with frequency-division section respectively, and the conversion of signals that frequency-division section is seen off is an international standard volume unit of measurement VU signal, and delivers to the A/D change-over circuit to the VU signal; The A/D change-over circuit is connected with single-chip microcomputer with the VU chromacoder respectively, is the VU conversion of signals that digital signal is given single-chip microcomputer and handled; Single-chip microcomputer adopts 51 series monolithics, and output is connected with interface circuit 8255A, and controls the rotation of motor through drive circuit.
The concrete change-over circuit of VU signal is as shown in Figure 2, and C2 plays time-lag action among the figure, and its value obtains too small; Then the VU signal changes too fast; The excessive VU signal of value reacted slow again, through actual debugging C2 value 20 microfarad to 100 microfarads (when being used for the whole tone music signal about desirable 20 microfarads, when being used to control the combination of spray type; Can get about 100 microfarads), value 20 microfarads here.
