The present invention relates to a music fountain device that synchronizes the output of music, fountain, and lighting, and in particular, since the operation timing of the fountain sprayed through the nozzle is synchronized by the music output to the speaker and the control of the PLC, the music, fountain, and lighting are synchronized. The present invention relates to a music fountain device in which the output of a music and a fountain are synchronized to be output at the same time to improve the effect of the music fountain.

In general, the music fountain device is a very dynamic and diverse fountain type for viewers by increasing or decreasing the height of the stream of water sprayed from the nozzle according to the level of music output through the speaker or by varying the appearance or lighting of the stream according to the music. It is provided.

However, the conventional music fountain device outputs the audio signal through the speaker as it is and controls the nozzle drive unit, the pump motor drive unit, the solenoid valve and the lighting control unit according to the level characteristics of the audio signal. Due to the time delay blasting through the nozzle, the music is first outputted through the speaker, and the fountain is operated. The timing of the music and the fountain is shifted, causing the viewer to feel aesthetically inferior.

In addition, Utility Model Application No. 20-2006-0023834, which additionally applies the time delay delay method to the inside of a general music fountain system, has a structure similar to the present invention, but the present invention is divided into a server and a system to be controlled at the same time and automatically. Compared to the TTS engine's digital control system that outputs text by voice and PLC control based on a schedule, the utility model is similar because it only adds a method of delaying sound to the analog system, which is an existing music fountain system. Can not.

Therefore, in order to solve the above problems, the music output to the speaker and the operating timing of the fountain sprayed through the nozzle controlled by the PLC are synchronized with each other, so that the music, the fountain, and the light are simultaneously output at the same time, thereby improving the effect of the music fountain. With the aim of providing a music fountain device that synchronizes the output of music and fountains to be made available, it is also necessary to use a computer to provide an automatic operating music fountain system based on a schedule schedule, and also to broadcast information such as announcements. The technology focused on providing an integrated music fountain management server computer that could also be used for promotional and emergency broadcasts by adding a text-to-speech engine that converts text to voice, if any.

Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings.

1 is a utility model application No. 20-2006-0023834 which additionally applies a time delay delay method to the inside of a general music fountain system, although the structure is a little similar to that of the present invention, the present invention is dually controlled by a server and a system. Compared to the TTS engine's digital control system that outputs PLC control and texts by automatic schedule, the utility model only adds a method of delaying sound into the analog control system. It can never be said to be similar.

Anyway, if the structure diagram of Fig. 1 is explained, it is possible to grasp the concept of the music fountain operation performed in the present invention.

1 illustrates a music fountain device in which music and fountain outputs are synchronized, an audio signal input unit 1 for receiving an audio (music) signal output from a CD, a hard disk, an MP3, and a radio, and the audio signal input unit. A characteristic detector (2) for detecting the magnitude level characteristic of the audio voltage signal inputted to (1) and supplying it to the PLC (3), and a nozzle driver in accordance with the magnitude level characteristic of the audio voltage signal detected by the characteristic detector (2) (4), a PLC (3) for outputting a control signal for controlling the pump motor drive unit (7), the solenoid valve (9) and the lighting control unit (10), and nozzle drive in accordance with the control signal of the PLC (3) The pump driving unit 8 supplies a driving current to the nozzle driving unit 4 for controlling the motor 41 to move the nozzle 43 in accordance with music, and to the pump motor driving unit 7 according to the control signal of the PLC 3. Inverter (6) and the control signal of the PLC (3) for the pumping operation of The solenoid valve 9 opens and closes so that the water pumped from the pump 8 is supplied to the nozzle 43, and when the control signal of the PLC 3 is inputted, the lamp is delayed by a predetermined delay time and then the lighting LED 11 ) And a delay unit for delaying the audio signal input to the audio signal input unit 1 by a preset delay time and outputting the audio signal to the speaker 14 through the audio output unit 13. It consists of 12 pieces.

And a control timing detector 15 for detecting the control signal output timing of the PLC 3, an audio output timing detector 16 for detecting the audio signal output timing output from the audio output unit 13, and the control timing. It is determined whether an error occurs by a predetermined delay time between the control timing and the audio output timing detected by the detector 15 and the audio output timing detector 16, respectively, and when the result of the determination is greater than or less than the delay time. It further comprises a compensation unit 17 for compensating for the delay time of the delay unit 12.

The above description is advanced in the general fountain system and adds a delay unit 12 and a compensator unit 17 to delay the sound inside the analog system so that the strength and weakness of the fountain are not matched when the fountain show actually starts. In the present invention, the sound is extracted using a computer as a signal having a three-step delay difference, and the visual and auditory sounds are naturally matched with the point where the fraction of the music rises to the strong part of the music. It is configured to view the matching Music Waterjet Show, and also automatically implements the music fountain system based on the schedule schedule, and when it is necessary to broadcast the contents such as announcements An integrated music fountain management server computer that uses a Text To Speech (TTS) engine that converts speech into voice. It was constructed in the ball system.

The TTS engine method used in the present invention refers to an engine that converts text to speech and reads the text. Therefore, text-based data applied from the outside is converted in real time to VOICE-based data using a text synthesis technology (TTS: Text To Speech), and the converted voice-based data is connected to a broadcasting system. If you do, it will be possible to broadcast. Therefore, the music fountain system used in the present invention is processed through the TTS engine as described above, for example, by connecting the sound of the announcement A announcements voices in the narration formula, while at the same time the fountain is programmed to match the voice You can show it.

In addition, in providing voice-based services (notices / messages / music, etc.), if the server computer system of the present invention can be accessed in the administrator mode on the Internet, the program can be controlled in the remote mode and the text message can be voiced. It may also be desirable to process and broadcast.

FIG. 2 is a waveform diagram illustrating output timing of an audio signal delayed by a sound delay timing controller in the present invention, wherein part d of (a) has a predetermined time difference from part d of (b). You will be able to see what the delayed waveform looks like.

Therefore, in the present invention, a timing controller (g: timing controller shown in FIG. 6) installed in the server computer system is not shown in FIG. 2A and 2B and further delayed (C). It is characterized by at least one delay timing controller for producing a waveform of.

In other words, in a server computer system for controlling a music fountain system, when one sound signal is received, a timing controller (g: timing controller) copies the sound signal in the server to have at least one delayed time difference. It may be desirable to generate and extract the delay time sound.

Figure 3 is an explanatory view showing structurally by dividing the sound applied to the present invention (high range, mid-range, low range), as described above, because the high and low trebles differ in the pitch of each other to use this principle 3 A way channel divider method is used. Channel dividers, also called cross over amplifiers, are sound field band splitters that can separate and extract a constant low, mid, and high frequencies by using built-in frequency cutting. In other words, using the frequency cutting volume (Frequency Cutting Volume), the low range is extracted by cutting from 500Hz, the mid range from 500Hz to 8KHz, the high range is extracted by cutting from 8Khz to 22KHz. Here, the frequency of each sound range can be arbitrarily adjusted by cutting volume.

In addition, by using the principle of the equalizer amplifier, one of the audio device is characterized in that the nozzle output method to reproduce the wave height of the waveform similar to the waveform meter embedded in the equalizer showing at least one voice frequency height.

To recapitulate, in order to control the output of the nozzle in at least one fraction using the above-described method, at least one low, mid, and high frequency signals using the channel divider principle are separated into at least one nozzle. The applied water jetting output method; In the equalizer amplifier, at least one of the water jet output methods applying the signals of the waveforms separated by frequencies to at least one nozzle by applying the principle of a waveform meter embedded in the equalizer amplifier showing at least one voice frequency height. It is preferable to apply the method.

FIG. 4 is a sound range diagram showing a masking spectrum, which is a sound range for each wavelength of a sound applied to the present invention, and extracts 3 mid-ranges of SB and 3 high-ranges of MS, and multiplies them by the controllers. We can create a signal that can determine the height of the fraction. In other words, if you set a thin thread fountain soaring high when the strong highs come out, and let the fountain with a large stem soaring high when the strong mid range comes out, Separately controlled amplifier) will be able to realize the same effect of the changing effects as the height of the bar graph type indicator window shines according to the pitch of the sound. In other words, it is possible to produce a waveform effect of a music fountain, which is characterized by applying a circuit in which the equalizer amplifier's LED window is changed by sound intensity and height to the sound control and divider (f: sound control & divider). Will and will be characterized.

FIG. 5 is a waveform diagram combining a minimum audible curve and a masking spectrum applied to the present invention. As described in detail with reference to FIG. 4, a low band of B1, a middle band of B8, and an ultrahigh band of B12 indicate the height of each bar graph. This is similar to the LED window of the equalizer amplifier described above, and it is preferable to use this frequency division extraction method in the present invention.

FIG. 6 is a schematic block diagram of a total waterjet control (TWC) server and a TWC system according to the present invention, so the detailed configuration of the present invention will be described with reference to the drawings.

First, the sound source used in the present invention is a digital source (a: digital source) such as wma or mp3, which is a compressed music file, as in the block of FIG. And analog sources (c: analog source) such as record plate (LP). The sound source extracted from the above source is processed by a system schedule management controller (d: schedule controller), d, which is a controller, is programmed in the form of a timetable or a broadcast schedule (see also the example of the schedule of FIG. As the voice goes out, the lighting and the fountain come together to create a sound.

Therefore, FIG. 7 may be referred to as an exemplary view of a broadcast time schedule table used in the present invention. Referring to the example of use based on FIG. 7, at <4 pm> on October 30, <exciting sky fountain show> Programmed at 4 pm, the music is automatically played and the fountain system is linked with the music to start the show.

At this time, if an emergency notification situation such as 4:50 occurs, when the user accesses the server computer system in the administrator mode on the Internet, enters the contents of the emergency notification in advance, and presses the reservation button, the time elapses after 4:50. e: TTS Module) automatically converts texts into voices during operation, so emergency notifications can be processed into voices and programmed fractional shows can be produced. .

In other words, the broadcasting, the fountain show and the lighting system are automatically interoperated and controlled by the timetable or the broadcasting schedule.

Meanwhile, f (f: sound control and divider) of FIG. 6 receives a signal from d and divides the sound into at least one signal by sound range, which is designed to be linked to f. g (g: timing control) is performed to delay the sound of f to at least one sound signal with a time difference.

The reason for doing this is

The downside of a typical music fountain show is that the sound is strong and the high stream of water must soar into the sky. In a typical fountain system, the short time that the sound is delivered to the viewer's ears, no matter how good the nozzle and motor output is. There was a disadvantage that the stream of the fountain show could not be raised to the maximum height. The reason why the strong, high stream of water soars into the sky only after the strong sound has passed is that the sound is delivered directly to the viewer's ear, but it takes longer for the tall key stream to rise, so the fountain and the sound play separately. There is a mismatch.

So, for example, if we assume that A is a strong sound that requires three seconds to reach the viewer's ear, and it takes two seconds for the stream to rise to its maximum height, Two seconds before the sound of A can be heard in the viewer's ear, a command signal that becomes a high stream should be issued.

Therefore, in summary, the operation of extracting and controlling the delayed sound source having at least one delayed time difference by using a time delay controller (g: timing controller) in accordance with the input point of the sound source (a, b, c) of FIG. It features. In this way, the sound and the streams of the fountain coincide with each other, and the viewer's eyes and ears will be natural.

Meanwhile, at least two signals (including a delay signal) passing through f and g of FIG. 6 are h (h: waterjet controller), which is a fractional controller, i (i: audio system), which is a sound controller, and j (j: input to the lighting system).

Here, I want to emphasize that the sound and light are fine, but there is a slight time difference. In other words, it is called thunder that sounds arrive late to our ears after our eyes confirm that the lightning strikes. Likewise, it is preferable to use a delay signal to operate the lighting system and the audio system in a music fountain. It is possible and characterized.

The overall description as described above is the block portion of the red line of FIG. 6, and can be referred to as a TWC Server (Total Waterjet Control Server), which is a comprehensive fountain management server that can be referred to as the present invention. TWC System can be referred to as a conventional music fountain system. In other words, the present invention refers to a TWC Server.

Therefore, FIG. 8 and FIG. 9 show examples of modern state-of-the-art fountains, and the system that operates the music fountain may be called a TWC system, which is a block part of the existing green line.

Although the configuration of the present invention has been described in the above-described principle, those skilled in the art can only newly devise various practical methods even by reporting only the above-described structural principles, so that such drafting also falls within the scope of the present invention if the principles of the present invention are applied. Will be self explanatory.

As described above, the present invention relates to a music fountain device that synchronizes the output of music, fountains, and lights. The present invention makes it possible to view a music waterjet show in which visual and auditory correspondence naturally. Integrated music fountain management server computer using TTS (Text To Speech) engine that inputs letters on the web and converts them into voices when it is necessary to broadcast the contents such as announcement while implementing music fountain system based on the schedule Because of the technical focus on providing the music, the naturalness of the music, the fountain and the lighting at the same time can maximize the effect of the music fountain.
