What are the components of the control system for a music fountain?

With the continuous improvement of the material and spiritual living standards of the Chinese people, various forms of music fountains can now be seen in the public squares, workplaces, and residential areas of many cities in China. Music fountain, as the name suggests, refers to the water shape of a fountain changing in a regular manner according to the melody and rhythm of the played music, supplemented by changes in lighting, laser or other media, forming a harmonious unity in people's visual and auditory senses, making people feel happy spiritually. 
The control system of the music fountain consists of the following parts: 
1. Collection and processing of music signals: 
In this process, the collection of music signals is completed by a music digital acquisition analyzer containing a DSP chip. At the same time as completing data collection, the music acquisition analyzer converts the collected signals into specific digital signals based on the elements and characteristics of the music signal according to the algorithm for analyzing music, and outputs them to the central music fountain control station industrial computer. The music acquisition analyzer is defined based on the functions performed by the device, and in reality, the device may not have this name, but may have another name. In the flowchart above, the part that completes music signal acquisition and transmission is a hardware device, but the part that completes music signal acquisition and analysis in the actual process can also be completed through a dedicated driver program for configuration software or a dedicated data acquisition program developed on the configuration software platform. 
2. The processing process of the harmonious correspondence between the water shape in the music fountain and the digital signal output by the music collection analyzer: In this processing process, the operator needs to configure the corresponding water shape for the music based on the melody played. The configuration can be stored in the program of the configuration software, and the parameters can also be modified as needed. In this process, the following modes can be defined according to the user's needs: 
Music automatic mode: In this mode, as the melody of the music changes during playback, the configuration software will send real-time data to the PLC strictly according to the water shape configuration set by the operator, and the PLC will output instructions to dynamically change the water shape to match the music playback, making the music fountain perform more perfectly. 
Music Random Mode: In this mode, the music fountain dynamically changes its water shape in real-time and randomly selected by the configuration software to send data to the PLC as the melody changes during the music playback. The PLC outputs instructions to dynamically change the water shape to match the music playback. 
Music manual mode: In this mode, the music fountain changes its melody during the playback process. The configuration software sends real-time and determined water shape instructions to the PLC, and the PLC outputs instructions to dynamically match the changing water shape with the music playback. 
Random mode without music: In this mode, the music fountain configuration software will select water shapes in real-time and randomly, send data to the PLC, and output instructions to dynamically change the water shape. 
Manual mode without music: In this mode, the music fountain configuration software sends the real-time water shape determined by the operator to the PLC to send data, and the PLC outputs instructions to dynamically change the water shape. 
In the above 5 modes, the video control can be used to observe the video footage sent by the camera installed on site in the configuration software screen, or to create corresponding 3D animations based on the water shape determined in the music fountain project to reflect the current water shape of the music fountain. At the same time, events can also be displayed and stored in the configuration software. The PLC receives data output from the configuration software and performs logical operations to control the opening and closing of corresponding water pumps, the opening and closing of solenoid valves, the actions and changes of lights, lasers, and various execution units.
