Detailed Description
In order to make the technical solutions of the present invention better understood by those skilled in the art, the present invention will be further described in detail with reference to the accompanying drawings and specific embodiments.
As shown in figure 1, the control system for the acousto-optic linkage of the intelligent lamp light comprises
The lamp is used for indoor illumination and rendering;
the audio acquisition module is used for sampling and logic operation processing of audio signals and classifying the frequencies of the audio signals;
the material module is used for providing data packets for compiling various scenes of the lamp and the audio acquisition module;
the storage module is used for storing the data information of each module;
and a control unit module which is respectively connected with the lamp, the audio acquisition module and the material module and calculates, logically and controls the output to realize acousto-optic linkage,
the lamp, the audio acquisition module, the material module and the storage module are respectively connected with the control unit module.
As shown in fig. 2, the material module includes a lamp bank, a recording material, a scene material, a microphone material, a voice control material, a cheering material, and a reverse cheering material. When designing a room light effect, firstly, a lamp is selected, and the effect made by the lamp is used. And in the traditional operation mode, each lamp needs to be programmed and debugged independently, so that the workload is large. In order to solve this cumbersome work, a material package solution is adopted. And making a data packet in advance before the lamp leaves a factory. Data packets such as a light library packet of a light fixture, a scene packet of a light fixture, a voice control packet and the like are collectively called as materials. Each data packet is used as 1 small module (namely material), and after the corresponding material exists, the effect of compiling the lamp is convenient, and the effect can be quickly realized as long as the material required by a user is selected. For example, in a 'K song' scene, a moving head lamp is supposed to move while changing the color, and a laser lamp also participates in sound control. The required effect can be directly selected from the existing materials. The user can control the lamp more simply, only one copy of the same data can be stored, and the data can be called by different scenes. The data of the whole system is greatly reduced, the data redundancy is reduced, and the data transmission time is saved. The memory of the hardware can be selected and configured to be smaller, and the BOM cost of the hardware is reduced.
The audio acquisition module adopts an ARM7 inner core, a 32-bit processor and a 120MHz central main processor MCU.
A computing part, a logic part and a control output part are arranged in the control unit module;
the calculating part comprises a motor action algorithm which adopts a Beziercurve algorithm, and the output of the driving motor is calculated by the central processing unit MCU. The action graph locates one graph by 12 points of data, and utilizes the Bezier curve principle: and 4 control points are used for calculating the shape of the Bessel curve graph through a cubic Bessel curve calculation formula P (t) ═ t × t (-P1+3 × P2-3 × P3+ P4) + t × t (3 × P1-6P2+ 3P 3) + t (-3 × P1+3 × P2) + P1, and 52 data points on the curve are selected between two adjacent points to serve as output data, so that each point can realize smooth transition, and various smooth motion graphs are realized.
The RGB color algorithm is used for matching different gorgeous colors through different combinations of RGB three colors, and the gradual change speed or direct hard cutting is realized between every two colors by controlling the size of the color variation quantity in unit time; in addition, different light running effects are realized through time difference and light-up sequence control. And various built-in effects are built in the programming device, so that the programming speed is improved.
The Bezier curve is applied to the control of the motor, the action effect of the lamp is controlled to be conveniently set, and the programming efficiency is improved. Because drawing with a computer mostly operates a mouse to grasp the path of a line, the feeling and the effect of drawing with a hand are greatly different. Even if a skilled painter can easily draw various figures, it is not easy to take the mouse to draw pictures at will. This is because computers can not replace manual work, so people are only quite funny up to now. Drawing using the bessel tool largely remedies this deficiency.
The logic portion comprises
The audio processing logic is responsible for acquiring audio through the audio acquisition module, the audio signal data is transmitted to the central processing unit MCU when being acquired, the matched material module is automatically called through the processing of the central processing unit MCU according to the frequency and the speed of songs, and the matched material module is output to the lamp after being calculated, wherein the central processing unit MCU controls the lamp to output different light effects according to different types of songs and simultaneously controls the acceleration value of the lamp;
the calculation formula of the acceleration value is as follows: acceleration value ═ set speed + (maximum speed-set speed) × (acceleration rate/maximum acceleration rate)
For example: the current speed maximum is 100 and the acceleration level maximum is 10 levels. If the current set speed of the lamp is 60%, the acceleration ratio of the voice control is 80%; if the current voice-controlled speed is 5 steps, the acceleration of the motor is 76,
the acceleration value is 60+ (100-60) × 80% (5/10) × 60+32 × 1/2 ═ 76.
The microphone shaking processing logic can automatically detect whether people use microphone shaking to sing songs or not through the central processing unit MCU, and can automatically switch to a specified light effect if people use microphone shaking to sing songs;
the drinking and inverse drinking operation logic inputs signals to the central processing unit MCU through keys to control drinking operation or drinking operation;

the time axis management logic controls the time of the thread of the material module operation, the voice control operation and the data recording operation through the central processing unit MCU;
and integrated control logic, the protocol functions of the air conditioner, the environment lamp, the power amplifier, the service lamp and the set-top box are controlled by the central processing unit MCU,
and the control output part is calculated and analyzed by the central processing unit MCU and then outputs the result to respective modules to realize functions.
The lamps are lamps based on a DMX512 protocol;
the lamps and lanterns are one or more of moving head lamp, laser lamp, stage lamp, handkerchief lamp and light beam lamp.
The lamps are all DMX lamps based on a DMX 512-light control transmission protocol. The equipment meeting the DMX 512-light control transmission protocol is marked with DMX512-A, and is called DMX512 protocol equipment for short. As long as the lamp supporting the DMX512 protocol is matched with the central processing unit MCU, the control and sound-light linkage function is realized.

and 4, step 4: the 1024 points for collecting AD data are converted into digital signals through the central processing unit MCU, and FFT results of the 1024 points are obtained by adopting FFU fast Fourier transform;
and 5: according to the FFT result, extracting the low-frequency signal defined as 32-192Hz and the high-frequency signal defined as 7500Hz, if the audio signal with the range of 32-192Hz and greater than 7500Hz is not extracted, returning to the step 2 to execute again;
step 6: outputting the low-frequency signal and the high-frequency signal in the step 5;
and 7: calculating the current rhythm speed of the song by the highest speed of the low frequency point of the output low frequency signal and the high frequency point of the output high frequency signal, and dividing the rhythm speed into 10 grades; finally, returning to the step 2 to resample the AD data; wherein, the closer the interval time of the same frequency is, the higher the speed is, the 1 grade is for less than 100 milliseconds, the 2 grade is for 100-200 milliseconds, the 3 grade is for 200-300 milliseconds, and so on. The FFT fast Fourier transform is cut and then transplanted to a central processing unit MCU, the high and low frequencies are detected in a pure software mode, and the BOM cost is reduced. Meanwhile, any frequency can be modified, and maintainability is improved.
