　　Music fountain is a kind of modern daily entertainment and leisure equipment integrating artistic beauty and music. From the most primitive pure fountain development trend to the present music fountain, and then to the later film fountain, it has gone through a road of rapid development and is becoming more and more beautiful and fashionable today. Today I will give you a basic principle of music fountain.

　　Music fountain reflects the meaning of music and the theme style of music through a variety of fountain design and the integration of colorful color lighting lamps. A good music fountain should be able to fully reflect the music through the transformation of water shape. The music control system software is added on the premise that the program flow controls the fountain. The electronic computer develops the decoder and number according to the identification of audio and MIDI data signals. Finally, the information is exported to the control system software, so that the shape design and lighting effect of the fountain can keep pace with the music, so as to achieve the perfect combination of the water type, light and color of the fountain and the music mentality, It is a plastic art that makes the fountain performance more lifelike, meaningful and reflects water. Music fountain: it can change according to the ups and downs of music. Customers can write their favorite music program flow on the writing page. The playing video system software can achieve the unification of music, water and lighting effects and atmosphere, and play video at the same time.

　　Simply put, the basic principle of the music fountain: in fact, it is to convert the digital audio into the electric frequency data signal. The electric frequency data signal controls the water pump according to the frequency converter, so that the working pressure of the water pump changes with the rhythm of the music. Control the water flow according to the music of playing video, so as to achieve the actual effect of synchronization with music. The water flow is controlled by the water pump, and the water pump is composed of three-phase asynchronous motor. If the speed ratio of three-phase asynchronous motor enters the DC switching power supply, the speed ratio is not changed. The frequency converter is a device for motor speed regulation. The speed of the motor is controlled by the frequency converter to change the water flow. Changing the working frequency changes the speed of the motor and the working pressure of the water pump. The different working frequencies of the music are sent to the control end of the variable-frequency motor through the 51 single-chip microcomputer, so that the motor power changes with the tone, rhythm and height of the music. With the change of the burden of the water pump, the amount of water sprayed changes. In addition, the fountain is generated by controlling multiple nozzles through multiple sets of machines and equipment. Change the pace and compressive strength of music into a control data signal, which then controls a working voltage control component. After the switching power supply controls the component through this working voltage, the output voltage also changes with the change of music, and then controls the water pump motor.

　　In the music fountain, some enterprises use the most advanced international distributed system electronic computer control system software based on WindowsNT. The system software has five characteristics: innovation, openness, applicability and safety factor.

　　The fully automatic control technology is the most critical technology in the music fountain, and its main characteristics are reflected in the following aspects:

　　1、 High quality music signal analysis system software

　　Using the international leading technology in the language recognition level of the Institute of automation of the Chinese Academy of Sciences, it has developed a 32-bit electronic computer solution system software (MUCs) for music data signals, which carries out spectrum analysis and delay resolution for music data signals, obtains relevant components of appropriate fountain control in music data signals and gives them to the main control chip computer, and can delay the music data signals at will, so that fountains and music can go together.

　　2、 Centralized and decentralized control system software

　　The fountain is immediately controlled by the master chip computer, which has the following features:

　　1. the function of music signal acquisition is to extract relevant components according to the characteristics of working frequency.

　　2. carry out fault detection for fountain machinery and equipment, and be able to diagnose the running status of server, power on and driving cabinet.

　　3. the Chinese menu type computer operating system enables the operators to learn the actual operation well in a short time. It has various dynamic modeling design and fancy transformation demonstration functions of the music fountain, enabling the operators to observe various changes of the fountain according to the computer screen, facilitating the music matching and application of the music fountain in a huge area.

　　4. the open structure, friendly industrial touch screen, communication interface and programming skills are open to consumers. The music fountain can be composed according to the two keys of the computer mouse. In this way, it is very easy to continuously improve the music fountain music library and always give people a fresh feeling.

　　5. immediately control the music fountain, and immediately push the pump, frequency converter or servo driver.

　　6. control the swing speed and direction of the swing motor, with a large control amount of 1024 or a large amount. The fountain controller uses MUCs system software, which can be connected with all audio (CD player, tape recorder, live performance, etc.) to ensure that the music data signal is accurate, so that the music and fountain can be completely synchronized.

　　3、 Safety and stability

　　1. each controlled machine and equipment is equipped with over-voltage, over-current and leakage protection switches. In case of failure, the power supply can be cut off automatically to stably ensure that the fountain machine and equipment in this road will not be damaged and ensure life safety.

　　2. a set of unique protective grounding methods are summarized from the practice of industrial production control engineering to further improve the safety factor.

　　3. part of the controller adopts contactless switching solenoid valve with high power on a large scale, which reduces the influence of electromagnetic induction flame, greatly reduces the common faults of the main circuit and increases the service life.

　　As a music fountain, it is unlikely to perform for a long time in a day. The first reason is that the power consumption is large, and the second reason is that it will lack a sense of mystery if it is opened for a long time. Especially in the daytime, when there is no lighting effect, the actual effect is poor. As a scene of all city squares, besides music performance, the fountain also needs to consider the expression effect of water type when it is a fixed tourist attraction. The use time of fixed water type is the most. Therefore, the design scheme and selection of fountain water type not only consider the artistic beauty of performing music, but also consider the actual effect as a garden waterscape, so the setting of control has a different role.

　　1. manual control: when the music performance is intermittent during the day or at night, click the mouse to open some water forms separately to produce a composition whose shape design is fixed and will not change. Energy saving, commonly used.

　　2. program flow control: if you expect to have different matching design changes, you can start the horizontal function to make the water type change according to the formulated system, produce different appearance, and make the human body have different beautiful scenery.

　　3. real time voice control: it is a control method widely used by most Chinese enterprises at this stage. Its characteristic is that it can respond to all audio data signals, play Karaoke on the spot, etc., but this control method has some defects. First of all, the water posture lags behind the music, making people feel that the fountain posture is incompatible with the music. Secondly, the occurrence composition and duration of the water type are fixed and repeated regardless of all the songs, so the emotion expressed by the performance of the water type and the music will be inconsistent. For example, the impassioned music Fu is likely to shake the water type, and when the rhythm is soft, the high and large water quality will occur, which makes the auditory system experience inconsistent with the visual experience. Third, the emotional passage of the song is inconsistent with the length of water type transformation, and it is the same.

　　4. pre editing control method: manually compile various water types, postures, lighting effects, and the opening and closing of water pumps according to the emotion and poetry of a piano music, so that the performance of the fountain is consistent with the emotion and poetry of the music. This function has a certain comprehensive difficulty coefficient at the level of control technology, electronic information technology and communication technology.
