Example 1

Referring to fig. 1 to 3, a first embodiment of the present invention provides an intelligent music fountain distributed control method, including:

s1: and reading the audio file, preprocessing the audio file, and editing and previewing the effect according to the preprocessing result.

The method comprises the following steps of:

(1) taking MP3 format as an example, the read audio file firstly initializes the decoder and reads the data of each block according to the definition of the data structure;

(2) analyzing the structural mode of the audio file information, and defining a structural body Frame for each Frame of information;

(3) and resolving the MP3 file into a Frame structure linked list with a time tag, and storing the Frame structure linked list.

The program code for defining the structure Frame is as follows:

s2: and automatically sending fountain action instructions to the field controller through the upper computer according to the preprocessing result and the playing speed of the audio.

The fountain action instruction is obtained through the following steps:

(1) configuring an action command;

(2) extracting rhythm lines through preprocessing to obtain corresponding beats, combining action instructions with the beats to obtain fountain action instructions:

the method of low-pass filtering analysis is adopted to filter high-frequency information, extract a low-frequency band audio frequency map, analyze peak intervals, automatically calculate beats and accent points, and automatically generate accent interval lines on a time axis.

Preferably, the embodiment can automatically perform the functions of automatically absorbing and dividing time blocks on the polyphonic interval lines during the music composing, thereby simplifying the music composing operation.

Further, the fountain action instruction is stored in the shared memory area, and the fountain action instruction is sent to the field controller through the upper computer.

Specifically, the working principle of compiling and sending the upper computer combined fountain action instruction is shown in fig. 2, and the working flow is as follows:

(1) calculating the instruction position: according to the current time, the starting time of the time block and the period of sending the command, the current command position of the motor can be calculated; generally, the cycle of sending the instruction is 3 times of the communication cycle, so that the communication thread sends the same instruction 3 times, which is to ensure that the instruction can smoothly reach the controller without being affected by the communication reason.

(2) Compiling and caching instructions: when editing the motion of the motor, the generated command is an original command, wherein a logic control statement (a loop or a subprogram call) is possible; the original instruction is compiled and cached into a group of simple sequential control instructions, so that the current execution instruction is convenient to extract; the compiling process is that each loop and nesting are expanded by utilizing recursion to form a group of simple instructions which are cached in a memory, the original instructions of the existing cache instructions are not compiled again unless modified, and all motor instructions to be called are generally precompiled before the song is played in order to improve the response speed of the program.

(3) Storing instructions to a shared memory area: after the arbitration thread calculates the current instruction to be sent, translating the instruction into a communication message according to the communication channel number and the communication position, and filling the communication message into a shared memory area; since the arbitration thread is only responsible for computing instructions, and the tasks of communication transceiving are executed in the channel sending thread, the security of the data in the memory area should be ensured by a shared lock when the two parties access the shared memory area.

(4) And finally, the channel sending thread accesses the data in the shared memory area regularly and sends the data to the field controller.

S3: the field controller receives the fountain action command and then sends a first control signal to the execution module 100 according to the water type configuration rule.

The site controller is responsible for executing control signals transmitted after being processed by the upper computer, and controls the execution module 100 according to a self-defined water type action combination (such as rectangular wave + rectangular wave, sine wave + triangular wave, flat wave + trapezoidal wave and the like).

It should be noted that the processor of the field controller can adopt a single chip microcomputer and a PLC; the field controller can be divided into the following functions: the water outlet controller (controls the height of the fountain water level), the motor controller (controls the speed of axial rotation), the light controller (controls the color of light), the laser controller (controls a laser projector), the projection controller (controls a projector) and the like can be conveniently added or deleted according to the scale and the user requirements, and a customized field controller can also be adopted, and the controller has higher integration level; the field controller of the embodiment has a multifunctional switching value output, a standard analog value output and a built-in communication interface circuit, supports various industrial control protocols based on TCP/IP, and communicates with an upper computer.

The "first control signal" refers to a corresponding instruction signal sent by the upper computer to the field controller according to an instruction of the control signal, and is used for instructing the execution module 100 to control the water flow.

S4: the execution module 100 utilizes the frequency conversion speed regulation technology to regulate the rotating speed of the water pump, and thus the flow control of the fountain water pump is completed.

The execution module 100 comprises a driving circuit, a fountain multi-dimensional nozzle, a fixed nozzle, a variable frequency speed regulator, an electromagnetic valve, a submersible pump, a colored lamp, a shaking head lamp and a stepping motor; wherein, the variable frequency speed regulator and the stepping motor are controlled by analog quantity; the electromagnetic valve and the submersible pump are controlled by using the switching value; the colored lamps are divided into true color 512 lamps and seven-color LED lamps, wherein the true color 512 lamps are controlled by analog quantity, and the seven-color LED lamps are controlled by switching quantity.

The basic principle of the variable frequency speed control technology is that according to the direct proportion relation between the rotating speed of a motor and the input frequency of a working power supply: n is 60f (1-s)/p, wherein n, f, s and p respectively represent the rotating speed, the input frequency, the motor slip ratio and the number of magnetic pole pairs of the motor; the purpose of changing the rotating speed of the motor is achieved by changing the working power supply frequency of the motor.

It should be noted that the direction of the nozzle of the music fountain is controlled by two stepping motors in the horizontal and vertical directions respectively, and the operation angle and the operation speed of the stepping motors are controlled by continuously adjusting the number and the speed of the input pulses of the stepping motors.

Specifically, referring to fig. 5, as an interface of the core module 500, the core module 500 includes a time block, a Layer hierarchy, a time axis, and an arbitration thread, which are used to execute the core function of the music fountain control system (determine what fountain effect should be executed according to the playing time of the current music); specifically, after a specified music file is loaded into a scene, through automatic parsing, a waveform diagram of the music is displayed on a time axis (a black bar scale part in fig. 5); the progress line (vertical line in fig. 5) indicates the current playing time (precision ms); the color bar blocks right below the time axis represent time blocks; the progress line moves to the right at a constant speed along with the playing of the music; when the progress line cuts to time blocks, it means that the actions required to be performed within these time blocks will be performed; each time block comprises configured effect parameters, and the arbitration thread analyzes the parameters, converts the parameters into executable instructions and sends the executable instructions to the corresponding controller.

The effect editing module 200 is connected with the core module 500, and provides various editors such as waveforms, frame actions, lights, motors and the like for a user to edit various special effects of the fountain; in order to facilitate the transplantation of engineering projects, the editors have the function of making effect templates; specifically, the effect editing module 200 includes a modeling control unit 201, a light control unit 202, a motor control unit 203, and a hand control unit 204.

Wherein, the model control unit 201 is used for setting a specific fountain model, which puts out a specific model by controlling the water yield of the fountain, and for regular models, the water type is generated by calculating a corresponding wave function, for example, fig. 6, and a model similar to a mountain peak can be realized by generating a triangular wave and configuring parameters such as a wave peak, a wave trough, a period, an execution interval, and the like, and similar effects also include: flat waves, oblique waves, rectangular waves, trapezoidal waves, sine waves, semicircular waves, and the like; some irregular modeling and dynamic effects can be realized by means of frame-by-frame editing, and as shown in fig. 7, a specific water type effect can be manually edited in a manner similar to that of editing a bitmap, so as to meet the special requirements of a user.

The light control unit 202 is used for controlling light of the music fountain; the light can decorate the music fountain in the night curtain, especially uses a large amount of underwater color lamps, and the cooperation laser and water curtain projection can show very good overall effect. For light control in a music fountain, the main configuration parameters are: color sequence, color change interval; the light control unit 202 can enrich the expression form of light by the way of light and water linkage, such as: a frame action editor is matched to put out a specific light pattern; the arrangement interface is shown in fig. 8, which is used to realize the gradation change of the light intensity according to the water output.

The motor control unit 203 is used for controlling the water outlet direction of the fountain opening and generating a spray pattern, and the motor control unit 203 of the embodiment can adopt an upper computer motor, for example; specifically, the two-dimensional music fountain can control the water outlet direction of the nozzle through motors in two directions of a Y axis (vertical direction) and a Z axis (horizontal direction) to swing various beautiful water bloom models; the core of the motor control unit 203 is a set of simple and clear sequence control instructions: move (pulse number, speed), rest (duration), loop (supporting infinite nesting), reset; then, an interface for configuring the sequential control instructions is provided through a motor action editor, and the combined action is stored as a motor action file so as to be convenient for subsequent multiplexing; before multiplexing these commands, the program performs the operations of compiling the combined command into a message data structure that can be finally sent to the site controller, and the command interface of the motor control unit 203 is shown in fig. 9.

The hand operation control unit 204 is used for debugging, testing and temporarily manually controlling music; when the hand control unit 204 is activated, the predefined groups in all scenarios will appear in the hand panel in the form of buttons, and the arbitration thread will no longer use the time axis as a criterion for deciding to perform an action.

The scene management module 300 is connected to the core module 500, and is used for virtual construction and grouping of music fountain elements, and is composed of elements, groups, and a channel management unit 301, wherein the elements refer to a single control point in a virtual sense, the groups refer to ordered arrays composed of a plurality of elements, and can be edited in a form of queues or matrixes, and the channel management unit 301 is used for managing communication between upper computer software and each field controller.

Specifically, each music fountain has its own unique design and layout, and the scene management module 300 virtually constructs one-to-one of the spring eyes in the upper computer software and reasonably groups the spring eyes; each element represents an actually corresponding control point, it should be noted that the fountain nozzle, a control motor (including horizontal and vertical dimensions) and a bottom spotlight form a whole, which is called a control point, and attributes of the control point include: the communication addresses of analog quantity (controlling water yield), switching value (controlling a switch valve), a Y-axis motor, a Z-axis motor, light and the like are in the following formats: the channel number + communication position (as shown in fig. 10), the channel management unit is responsible for managing the connection of the channel, and according to the requirement of the arbitration thread, encapsulates the instruction into the specified industrial communication protocol, and sends the instruction to the field controller periodically (cycle 20 ms); the channel attribute includes an IP address, a port number, a data (protocol) type, a data length, and the like; the data type is a scalable structure, and each option corresponds to an industrial communication protocol based on TCP/IP; such as ModbusTCP (analog/switching), DMX512 (light), PJLINK (projection), etc.

Preferably, the intelligent music fountain control system provided by the present invention relies on the channel-type and scalable industrial protocol to realize integration of various controllers and devices, and fig. 11 is a debugging interface of the channel management unit 301.

The comprehensive preview module 400 is connected to the core module 500, and is configured to support a real-time updated three-dimensional display window and display a preview effect that should be reflected by the entire scene at any time on the time axis; the music fountain has a reasonable overall arrangement on the time schedule from design, construction to acceptance; after the design drawing is finished, the scene configuration and song arrangement of the software can be synchronously carried out along with purchase and construction; at this time, the on-site debugging feedback function is not provided, so that the comprehensive preview function is very important for the music fountain control system; several of the main elements of the integrated preview module 400 are: spout (plane coordinate), water outlet (three-dimensional vector), light, camera (multi-view angle); the comprehensive preview module 400 based on opengl (open Graphics library) can well coordinate the above elements; the composite preview window is shown in FIG. 12; OpenGL provides a pure three-dimensional scene, which naturally solves the problem of multiple viewing angles; wherein, the fountain effluent is realized by simulating the gravity effect by using the particle effect; the light is realized by a conical light source; the rotation of the two-dimensional motor is simulated by using a Transform (transformation coordinate system) method;

the steps of drawing the virtual three-dimensional scene by adopting OpenGL are as follows: (1) initializing a three-dimensional scene: setting the position and the lens direction of a camera, setting a sky box and a sky light (parallel light source), drawing a water surface, and simulating water waves (the setting principle is shown in figure 13); (2) rendering model objects within a three-dimensional scene: the method comprises the following steps of (1) generating standard OBJ files by modeling software such as 3DMAX and the like, wherein the standard OBJ files comprise fountain peripheral buildings, rockeries and the like; the music fountain control software takes an OBJ file, converts a three-dimensional model into dot matrix data, combines and reads model material information such as diffuse reflection light, a mapping and the like, and restores the model material information into a scene by using a drawing function provided by OpenGL; (3) simulating the water column ejected from the nozzle with a particle effect: each nozzle object comprises a limited number of particle arrays, and new particles are generated and old particles are dead in each calculation period so as to maintain the number of the particles in the arrays; by calculating the X-axis and Y-axis angles of each nozzle in the core process of the core module 500, the injection vector and the initial velocity of the nascent particle can be obtained; the flight trajectory of each particle after birth is the result of the combined action of the jetting vector, the initial velocity and the gravity; in particular, a slight random offset of the jetting vector can be given to simulate the effect of water bloom agility; the flow chart of drawing a virtual scene by using OpenGL is shown in fig. 14.

The working principle of the system is as follows: establishing corresponding groups and elements in the scene management module 300 according to a design drawing of the music fountain; configuring the attribute of a channel according to a field network topological structure; next, fountain effect editing is performed in the effect editing module 200, and the pre-edited effects are added to the time axis in a layered manner and are called when songs are played; effect recommendation can also be performed by using the modeling library through extracting the music characteristics; the edited effect can be previewed through the comprehensive previewing module 400 so as to correct the effect details; the arbitration thread in the core module 500 performs strict clock management, and integrates the information provided by each module (the effect editing module 200, the scene management module 300, and the integrated preview module 400) to decide what kind of instruction should be executed to the field controller at the current time, and finally instructs the field hardware such as the pump, the motor, the frequency converter, and the like to coordinate the music action through the field controller, so as to realize the specified effect of the music fountain.

Example 3

In order to verify and explain the technical effects adopted in the method, the embodiment selects a traditional control method and compares the traditional control method with the method so as to verify the real effects of the method.

The traditional control method has the following defects: (1) the program is decentralized controlled, the operation and management are not centralized, and the original sequence control program is divided into a plurality of groups of controllers for respective automatic control according to the functions (water outlet, light and motor control); (2) the communication transmission media and the protocols are not uniform, and industrial protocols based on motion control and common analog/switching value control are mixed for use; hardware equipment based on twisted-pair wires and an industrial bus is used in a mixed mode; (3) the method lacks intelligent auxiliary music composing means, such as automatically capturing the beat of the song, extracting the characteristics of the music, recommending the water yield along with the waveform and the pattern of the music, and the like; (4) the function of comprehensive real-time preview of the composed music is lacked, and the harmony problem cannot be found in time in the pre-compiling stage through actions such as water outlet, light, a motor and the like; (5) the motor control instruction is not intelligent enough, and has no configuration and automatic compiling function.

Compared with the traditional control method, the method can provide modeling library management function, carry out effect recommendation according to different music characteristics, complete effect actions of various water types or lamplight, simplify grouping, provide recommendation and help for scene configuration, effectively shorten construction period and save workload, and the control period only needs 20 ms.

Specifically, in order to make the overall effect of the fountain conform to the rhythm of music, the rhythm or time block needs to be edited according to the music beat/stress during music composition, if the work is performed manually, each time block needs to be aligned manually, or the execution interval time of actions is set according to the beat, so that a large amount of work is consumed; the method comprises the steps of reading the waveform of a music playing file, filtering high-frequency information by adopting a low-pass filtering analysis method, extracting a low-frequency-band audio frequency map, analyzing peak intervals, automatically calculating beats and accent points, automatically generating accent interval lines on a time axis, and automatically performing functions of time block automatic adsorption and automatic division on the accent interval lines during music composition, so that music composition operation is simplified.

The music fountain is controlled by the method, the actual field fountain effect is as shown in figure 17, and the comparison of figure 12 shows that the actual field effect is consistent with the comprehensive preview effect, so that the unification of preview and engineering practice is realized.
