Description

Music fountain control system

Technical Field

The utility model belongs to the technical field of the fountain and specifically relates to a music fountain control system.

Background

The fountain is a combination body with a specific shape which sprays water or other liquid through a nozzle under a certain pressure, and the fountain provides water pressure and is generally a water pump. Fountain landscapes can be broadly divided into two categories, namely, the fountain landscapes are manufactured according to site landform structures and imitating natural waterscape according to local conditions, and fountain equipment is completely relied on for artificial landscaping. The fountain is a water landscape which is constructed by manpower or in a natural fountain pool and sprays beautiful water to be enjoyed by people. The fountain is an important landscape, is a waterscape art, embodies the combination of moving and static, forms bright and lively atmosphere and brings aesthetic enjoyment to people. With the application of the light, electricity, sound and automatic control device on the fountain, the music fountain, the intermittent fountain, the laser fountain and the like are formed, so that the content of the fountain is enriched, and the double feelings of people in vision and hearing are enriched.

The music fountain is added with a music control system on the basis of a program control fountain, a computer decodes and codes audio and MIDI signals through identification, and finally outputs the signals to the control system, so that the shape of the fountain and the change of light keep synchronous with music, thereby achieving the perfect combination of fountain water type, light and color change and music emotion, and leading the fountain performance to be more vivid and richer in connotation and embody the water art. The music fountain can change according to the fluctuation of music. The user can compile the music program of oneself liking at the editing interface, and its play system can realize that music, water, light atmosphere are unified, and the broadcast is synchronous. Therefore, there is a need to design a music fountain control system.

SUMMERY OF THE UTILITY MODEL

In order to overcome the defects in the prior art, a music fountain control system is provided.

The utility model discloses a following scheme realizes:

the utility model provides a music fountain control system, includes water pump and the shower nozzle that corresponds the intercommunication with it, the water pump corresponds the electricity with the converter and is connected, the converter corresponds the electricity with IO expansion module and is connected, IO expansion module still corresponds the electricity with analog-to-digital conversion module and color lamp drive module and is connected, analog-to-digital conversion module corresponds the electricity with the stereo set system and is connected, color lamp drive module corresponds the electricity with L ED color lamp and is connected, IO expansion module corresponds the electricity with P L C and is connected.

A Smith prediction compensator is arranged in the P L C.

The L ED color lamps include one or more of a single color, a dual color, and a multiple color.

The frequency converter comprises a main circuit and a control circuit, wherein the main circuit comprises an input power supply and an output power supply, the control circuit comprises a switching value control circuit, an analog value control circuit, a fault detection circuit, an analog voltage output circuit and a collector open-circuit output circuit, and the main circuit and the control circuit are correspondingly and electrically connected through terminals.

The utility model has the advantages that:

the utility model relates to a music fountain control system adopts P L C and converter, according to the change of music rhythm, has realized the intelligent control of music fountain through the analog-to-digital conversion module, possesses easy operation, overhauls characteristics such as aspect.

Drawings

Fig. 1 is a block diagram of a music fountain control system of the present invention.

Detailed Description

The preferred embodiments of the present invention will be further described with reference to the accompanying drawings in which:

The sound system of this embodiment includes the sound card, the sound card obtains the sound analog signal from hardware equipment such as sound system's microphone, the sound analog signal passes through analog-to-digital conversion module with the sound analog signal from sound wave amplitude signal conversion to digital signal, then transmit to P L C.P L C through the IO expansion module and control the converter according to the digital signal that receives, the power of converter control water pump, and then the water column height of control shower nozzle, thereby realize the harmonious unity of the water column of fountain and music.

In addition, a Smith estimation compensator is arranged in the P L C, dynamic characteristics of the process under basic disturbance are estimated in advance, and then the estimation compensator compensates, so that the delayed regulated quantity is reflected to the regulator in advance, and the regulator acts in advance, thereby eliminating the control of mechanical inertia and the like on the music fountain.

In an intelligent music fountain, because of the characteristics of more control points and high real-time control requirement, an analog-to-digital conversion module and a frequency converter are adopted as peripheral modules controlled by P L C in hardware processing, the P L C is communicated with the analog-to-digital conversion module and the frequency converter through an I/O expansion module, and in a design system, L ED colored lamps are utilized to further display the effect of the intelligent audio fountain and are combined with the fountain for use, so that the ornamental value of the fountain is more perfect.

In the embodiment, a pair of dual waterproof L ED lamps is arranged below each spray head, in the upper computer programming, a P L C monitors the music frequency collected by the digital-to-analog conversion module, the L ED colored lamps are started when the monitored music frequency reaches a set value, and the luminous intensity change of the L ED colored lamps can be controlled by the colored lamp driving module to enhance the night viewing effect of the intelligent music fountain.

The utility model provides a shower nozzle of music fountain can change according to sound system's music rhythm (frequency), thereby change the height that the shower nozzle sprayed water, in practical application, upper computer (not drawn in the attached drawing) adopts the VB programming, utilize computer and the P L C communication of this application, carry out real time monitoring to the next computer of this application, in this embodiment, divide five concentric circles altogether and set up 36 shower nozzles, every shower nozzle all is connected with a corresponding water pump one-to-one, send control command control to the converter through P L C, the converter and then control the opening and close and the running power of water pump, reach the purpose that the control shower nozzle goes out water.

The program in P L C is developed correspondingly according to the user's requirements, and downloaded to P L C after the development is completed, and the specific process and principle thereof are well known technologies and will not be described herein again.

Although the invention has been shown and described in detail with respect to the preferred embodiments thereof, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
