Description

The music fountain control device

The utility model relates to a kind of music fountain control device, is particularly suitable on all kinds of fountains of big and medium-sized cities dress and uses.

Deep development along with reform and opening-up, urban construction is fast development thereupon, not only high building stands in great numbers, and sight spot, garden district, incity, fountain and music fountain also are seen everywhere, to beautifying the appearance of the city, environment purification has played the effect that can not go out, however, because the controller of artificial in the past music fountain, it is the switch of controlling the multichannel magnetic valve according to the power of music source signal by control circuit, time, quantity, and then realize the flow of fountain water and the size of lift, be complementary with music, harmonious, find by actual motion, slower because of electromagnetic valve switch speed, make the serious hysteresis of control, only open again, close two states, cause the water of fountain to superpose piecemeal and can not change continuously, make it to disconnect asynchronously, obviously reduce appreciation effect with music; Simultaneously because the condition of work harshness of magnetic valve, the situation that faults such as, sealing leak aging such as diaphragm cause stop-spraying to change the part maintenance happens occasionally, and further improved necessity is arranged for these reasons.

The variation that the purpose of this utility model is to provide a kind of variation of fountain and music synchronously, the height of water column with music strong and weak change continuously, fully manifest its view and admire whole ideal effect, stable and reliable for performance, change flexibly, convenience, long service life, music fountain control device that fault rate is low.

The purpose of this utility model realizes by the following technical solutions, the automatic control circuit of this control device, comprise music source and pump motor, the output of its music source connects the input of amplification filtering circuit respectively, its output end vo ut, GND connects the frequency setting voltage input end and the frequency setting common port of frequency converter respectively, the output of frequency converter connects the anode of three bidirectional triode thyristors respectively, the lead-out terminal of Programmable Logic Controller is succeeded electric apparatus coil, the two termination silicon controlled anodes of relay normally open contact and the control utmost point, silicon controlled negative electrode respectively with the input A of pump motor, B, C links to each other.

The input GND of described amplification filtering circuit meets L ₁: the positive input 3 of A, R ₁With R ₂Meet L after the parallel connection ₁: the reverse input end 2 of A, R ₃With potentiometer W ₁Polyphone back R ₃End and R ₁With R ₂And interface links to each other W ₁End is plugged in L ₁: output 1 and the D of A ₁Between, D ₁The other end through capacitor C ₁One be terminated at L ₁: the positive input 5 of B, C ₁Other end ground connection, L ₁: the reverse input end 6 of B links to each other with output 7, and 4 pin of L:A connect+12V, and 11 pin connect-12V.

The operating frequency of described frequency converter is 20-50Hz.

The utility model compared with prior art, because automatic control circuit has adopted a series of technical measures such as amplification filtering, frequency converter and Programmable Logic Controller and have through evidence that the variation of fountain changes synchronously with the variation of music, the height of water column changes continuously with the strong and weak of music, fully manifest it and view and admire whole errorless, the long service life of ideal effect, precise control, advantages such as fault rate is low are implemented simultaneously easily, are beneficial to and apply.

Fig. 1 is the circuit theory diagrams of the utility model amplification filtering circuit.

Fig. 2 is the circuit block diagram of the utility model automatic control circuit.

Embodiment of the present utility model is described in conjunction with the accompanying drawings, and the sound channel output of recorder meets the input V of amplification filtering circuit respectively _L, V _R, GND, output end vo ut, the GND of amplification filtering circuit connects the frequency setting voltage input end and the frequency setting common port of frequency converter respectively, inverter output terminal connects the anode of three bidirectional triode thyristors respectively, the lead-out terminal of Programmable Logic Controller is succeeded electric apparatus coil, the normally opened contact two termination silicon controlled anodes of relay and the control utmost point, A, B, the C of three silicon controlled negative electrode water pump motor input terminals.The input GND of described amplification filtering circuit meets L ₁: the positive input 3 of A, R ₁With R ₂Meet L after the parallel connection ₁: the reverse input end 2 of A, R ₃With potentiometer W ₁Polyphone back R ₃End and R ₁With R ₂And interface links to each other W ₁End is plugged in L ₁: output 1 and the D of A ₁Between, D ₁The other end through capacitor C ₁A termination L ₁: the positive input 5 of B, C ₁Other end ground connection, L ₁: the reverse input end 6 of B links to each other with output 7; 4 pin of L:A+12V, 11 pin connect-12V.The operating frequency of frequency converter is 20-50Hz.

When the utility model uses, give last power supply, broadcast music, L ₁: A amplifies output to music signal, sends into L behind rectifying and wave-filtering ₁: 5 pin of B, voltage signal of output is given the frequency setting voltage input end of frequency converter after amplifying again, frequency converter has correspondent frequency according to the difference of voltage signal, Programmable Logic Controller makes its conducting according to the procedure triggers controllable silicon simultaneously, then the voltage signal of frequency converter end output is added on the pump motor, motor has different corresponding rotating speeds directly to control the discharge pressure of water pump according to the size of signal, flow, make the water column height, synchronous variation takes place in strong and weak power with music signal, export to controllable silicon when Programmable Logic Controller and close signal or music when stopping, fountain is stop-spraying thereupon, and then realizes the fountain sound control, the time control process.
