The water shape in the music fountain and the digital signal output from the music acquisition analyzer correspond harmoniously. In this process, the operator should configure the corresponding water shape for the music according to the melody of the music. The configuration can be stored in the configuration software program, and the parameters can also be modified as required. In this process, the following modes can be defined according to the needs of users: 1. Automatic music mode: in this mode, with the change of melody during music playing, the configuration software will send data to PLC in real time in strict accordance with the water shape configuration set by the operator, and PLC will output instructions to dynamically change the water shape to match the music playing; Music random mode: randomly select the water shape configuration to send data to PLC, and PLC outputs instructions to dynamically change the water shape to match the playing of music. 2. Music manual mode: music fountain manufacturer in this mode, with the change of melody in the process of music playing, the configuration software will send the operator's real-time and determined water shape command to PLC, and the PLC will output the command to dynamically change the water shape to match the music playing. 3. Random mode without music: in this mode, the configuration software will select the water shape in real time and randomly, send data to PLC, and output instructions from PLC to dynamically change the water shape; No music manual mode: the music fountain manufacturer sends the water shape determined by the operator in real time to the PLC to send data, and the PLC outputs instructions to dynamically change the water shape.
Most ancient civilizations had urban water storage pools to preserve drinking water. The Greeks and Romans used water pipes to send water to all parts of the city, but also used gravity to let water spout out. So the fountain in the square actually provided free drinking (and domestic) water at the beginning of its origin. This function still exists in many fountains in Europe and America until now. In the middle ages, the public water delivery system basically disappeared. Most of the public fountains in Europe were abandoned and only appeared in literary works or private gardens. The fountain in the square also symbolizes the source of life, innocence, wisdom and the garden of Eden. During the Renaissance, Europe began to rebuild fountains as public buildings, mainly as sculptures and decorations. At present, a large number of beautiful fountains on the streets of Rome were mainly built in the 15th and 18th centuries. What aspects should be paid attention to in the design of square fountains? In recent years, square fountains are relatively common and have become a beautiful landscape. The design of square fountains is also an important issue in square fountains. Therefore, two aspects need to be considered
With the continuous improvement of our people's material and spiritual living standards, various forms of music fountains can be seen in citizen squares, units and residential quarters in many cities in China. Music fountain, as its name implies, means that the water shape of the fountain changes regularly according to the melody and beat of the music, supplemented by the changes of lights, lasers or other media, forming a harmonious unity in people's vision and hearing, so that people have a pleasant feeling in spirit.
1. the pump type is finally determined based on the fountain hydraulic calculation results. The specification and main performance of the water pump can be basically understood through the nameplate (1) Pump model: according to the flow, head, size and other types of feed pumps, there are two types of models, old and new; (2) Pump flow: refers to the water output of the pump in unit time, expressed in or; (3) Pump lift: refers to the total lift height of the pump. Vacuum height is allowed. This is to prevent cavitation when the water pump is running. The safe height of water absorption determined through experiments has left a safe distance of 0.3m. This index indicates the water absorption capacity of the pump, which is the basis of the installation height of the pump. 2. the selection of pump type is based on the two main factors of flow and head. The method is as follows: determine the flow. The total flow is calculated according to the water power of the fountain. Determine the lift. The total head is calculated according to the water power of the fountain. Select the water pump. The selection of water pump shall be based on the determined total flow and total head, and it can be selected by checking the nameplate of water pump. If the fountain equipment needs two or more pumps to lift water (Note: when the pumps are connected in parallel, the flow increases and the pressure remains the same; when the pumps are connected in series, the flow remains the same and the pressure increases), calculate the flow of each pump by dividing the total flow by the number of pumps, and then use the pump performance table to select the pump. When checking the table, if both types of pumps are applicable, the model with low power, high efficiency, small impeller and light weight should be preferred.
The design and planning of large-scale music fountains can be divided into the following two categories: tailored according to the site potential structure, large-scale music fountains are designed and manufactured by manufacturers imitating natural waterscape, such as wall springs, springs, fog springs, pipes, streams, waterfalls, water curtains, water falls, water waves, whirlpools, etc. Completely rely on fountain equipment for artificial landscaping. There are music fountains, programmed fountains, swing fountains, running fountains, light fountains, amusement fountains, super high fountains, laser water screen movies, etc. Regular fountain pools are often used in open places. The pool should be large, the water spray should be high, and the lighting should not be too rich. In slender places, such as the corner of the street and in front of buildings, the pool is mostly rectangular. Most of the cisterns beside the modern houses are round or rectangular. The water volume of the fountain should be large, the water sense should be intense, and the lighting can be relatively rich. The way of the fountain is free and can be combined with various decorative pieces such as sculptures, but the change should be concise and the color should be simple. Music fountain planning requirements: the pipe chamber shall be cleaned before the pipeline installation, the main pipe shall be horizontal, the riser shall be straight and the main pipe line shall be fixed, the rust and welding slag shall be removed before the pipeline is painted with anti rust paint, and the water pump device shall be solid and stable. Lighting device: positioning of lamps and lanterns, manufacturing of lamp clips and fixing of lamps and lanterns.
The selection of nozzle materials plays an extremely important role in the entire fountain project. The nozzle needs to be soaked in water for a long time and exposed to the atmosphere. In this environment, the nozzle material is extremely prone to damage, such as oxidation and rust, poor wear resistance, and other problems. So how to choose nozzle materials?
