Symphony voice is a musical fountain, a comprehensive modern technology and art. Modern fountain complex and diverse variety of body movements, rapidly changing, but also consistent with the music synchronization, so the computer control system to the automatic selections to complete the musical fountain, synchronous presentation, control and storage of music, and all information and data processing and monitoring the process of running . Therefore, computer-controlled fountain has been in the music plays an important position, with the development of multimedia and artificial intelligence, computer control of the development to the fountain from a simple music management, computer music and computer integrated multimedia simulation of the fountain system. Limited water supply and drainage areas of expertise, this can not be on the computer and control technologies described in detail, but want to process text for designers fountain - water supply and drainage engineers to understand the modern musical fountain in the control of the latest technology.

1. musical fountain pump power supply system in the large musical fountain, the inverter power supply with a total capacity of the motor will be large, the number of pumps will be many. At the same time, they need to have a variety of individual supply frequency. Thus, as a variable frequency power converter will spend a lot of investment. Can focus on rectification, AC into DC first, and then the tone control for each channel using a pump inverter, the DC conversion into a variety of different frequencies of AC power to the pump motor power supply. This is a saving can be reduced not only the best solution to control the equipment investment. In the centralized rectification, the rectifier can complete them as a rectifier with a table stand, and with the automatic switch to increase the reliability of electricity supply. Current inverter has industrial products, such as Germany Shilai Fu inverter produced a reliable electrical performance, the design lifetime of 15 years, for ambient temperature -10 �� ~ 40 ��. Most inverter with RS485 or SPI serial communication interface. Each way RS485 computer interface connection 32 inverter. This is no longer needed on the computer D / A converter interface.

2. musical fountain pump fountain sound control PWM Speed Control There are two main ways: (1) pump motor speed; (2) control the size of the nozzle opening and closing the valve. Valve has the advantages of fast response, easy jump for the rhythm; in the computer under the control of pump speed, the diverse, more appropriate to meet the lyrical and elegant melodies. General musical fountain pump speed control without the use of high-precision drive, as long as 10:1 speed range of AC voltage control system to meet the requirements. Due to the recent rapid development of power semiconductor devices, high voltage and high current MOSFET or IGBT driver circuit applications are very common. Therefore, the control computer 50 for multi-cycle alternating current PWM modulation, you can get multiple different modulation index of 50 cycles AC. They were then driven MOSFET or IGBT, will produce 50 different frequency AC voltage, AC voltage to achieve simple speed control.

3. Fountain rocking body positioning and speed control position and rocking fountain is to produce changes in velocity of water-chic charm rocking an important factor. Fountain rocking body position sensor should be non-contact positioning device waterproof. Magnetic induction is frequently used by the Hall sensor, photoelectric sensor or optical fiber to guide the rotating magnet position encoder. For example, a fountain with position encoder positioning device swinging bodies, including: swing motor shaft mounted position encoder, high-speed counter, control computer and communications interfaces. Induction motor involves the precise method by which parking braking problems. Use of dynamic braking mode, the stator leads to DC braking torque generated braking torque at zero speed is zero, to achieve accurate and parking purposes. As the general swing rod bodies have a greater gap, in order to achieve precise positioning can only swing from one direction to reach institutional anchor in order to ensure repeatability. Therefore, institutions need to stop when you swing, each must reach the anchor point from one direction. Positioning accuracy by swinging movement organizations and the resistance moment of torque. Movement depends on the motor torque and the power supply before stopping the movement speed, and moment of resistance from the friction of bodies swaying, water flow, wind, etc. around the synthesis. Can see that these are not pre-determined factors. Therefore, in order to achieve precise positioning, we need to change the control parameters each time. The use of motor braking control parameters to precise positioning generally have two DC braking current size and start braking time. Computer control is the use of more convenient way to change the braking time. In the control system, motor braking time can be detected in place to amend the deviation point. Swing body positioning deviation according to statistics calculated by the mathematical model, and finally determine the braking time. When the velocity of body sway to the rhythm of sync with the music to get its required speed, and swing the motor speed. Since speed is the displacement of the time differential, so the motor shaft from the swing position encoder pulses sent to the computer can find its velocity.

4. musical fountain musical fountain control computer control software including automatic selections, water-sync with the music, water-based program demonstrates, colored lights of the program demonstrates, with the volume of water type move with the rhythm of the water-type move, the sound delay control.

4.1 automatic selections of music being played musical fountain from the computer's CD-ROM disc can be played directly tower. When the operator identified in the music database, presentation music, the computer control system automatically from the CD-ROM tower to find the CD in which you want to play a CD drive, then start the drive, the right to play the selected song. If you select the music when the disc is not CD-ROM tower, will be automatically revealed. 4.2 Water-based synchronization with the music when the music starts playing, the water type will be synchronized presentation. At the end of the previous track and next track began intermittently during the water-stop and will continue to demonstrate to keep pace. Computer control system can adjust to provide the sound delay, a variety of different capacity pumps, a different delay, so that water-effects to synchronize with the music. 4.3 The program demonstrates water-fountain water pump motor is controlled by the computer system programs, each of which pumps a song by the music playing from the start are specified in data sheet. Pump some parallel control is also affected by water-in-action demonstration of process control. 4.4 color lights, fiber optic lighting and laser irradiation of the program demonstrates the demonstration program with the water-like, color lights, fiber optic lighting and laser procedures are also controlled by the computer system. Fiber optic lighting with computer controlled stepper motor driven rotating disc and the color cover color. The laser light is scanned by a computer on the fiber. Wavelength laser source is controlled by the computer to change the laser and brightness, achieve a variety of color patterns. 4.5 volume of water-based servo control for some of the water type, the modeling requirements in the arts and music with the move, make music out of music fountain show, the content and feelings. This type of ups and downs of water is generated by the sound control. Play in the data sheet music, sound level on the strength of the control weighting factor two, one is the weighted section of the entire song, the other is in the paragraph on one or a few water-weighted. This demonstration effect can make the musical fountain and themes more explicit. 4.6 Water-based servo control the rhythm of the water for some type of jump and swing to the rhythm of sync with the music, performing a musical fountain of passion and vitality. This type of jump and swing the water change is also generated by the sound control. First, the computer curve from the music volume to remove the rhythm; Then, the control pump motor start and stop or speed up, so that the nozzle of the currents synchronized with the rhythm of the beating. 4.7 Time Delay Control of voice sounds in the music fountain in the delay control is used several times. This refers to the sound delay control is watch the fountains at different landscape positions, there will be no music and water-based synchronization. Therefore, the computer control system can adjust to provide the sound delay, so that the audience stood in different locations, to synchronize the results. 4.8 Fountain electricity load automatic control and protection more than the maximum power consumption when the fountain agreed load, the computer control system will automatically cut off some of the pump power, bringing the total load does not exceed the quota. Computer monitoring system to the power of each phase voltage and current waveforms stored to calculate the effective voltage, effective current, active power, reactive power, power factor and so on. Therefore, the computer monitoring system in a very short period of time when determining the amount of current over-current and duration of using computers for non-fuse overcurrent protection, 5μs time in the output of the circuit turn-off accidents.

5. musical fountain musical fountain in the computer-aided music software music database, each song has its own music player data table. Play music in the score data table generated by the computer, but it is up to the music were a way to choose a water-based and light, that is, to the music by hand. Artificial music is a very careful and need to work smarter and create art. Computer music software music fountain is an artificial intelligence expert system, and a fountain of music knowledge base composition. It provides a simple statement to describe the questioning this song or a certain phrase, "knowledge" such as music classes, rhythm and speed, emotional level, the number of people playing or singing, musical instruments and other species. Subsequently made by a computer presentation program of several fountains for operator selection. If no one choice, it also has a default program, the realization of automatic water combination. Music produced by a music fountain control data into the database. In the computer control software also offers a variety of typical music program. Such as marches, dance music, ballads and pop songs such as jumping. When you select one of the typical music program, you do not have the musical fountain shows with music can be.

6. Multimedia Music Fountain Simulation and real-time monitoring when the first music piece is completed, the musical fountain in the demonstration effect can be achieved with a multimedia virtual simulation.
