Brief description of the drawings
Below in conjunction with drawings and Examples, the utility model is described in further detail, in accompanying drawing：
Fig. 1 is the electricity of adaptive lamp light control system one preferred embodiment of the present utility model based on stage set sound
Road schematic diagram.
Embodiment
In order to which the technical characteristics of the utility model, purpose and effect are more clearly understood, it is detailed now to compare accompanying drawing
Illustrate specific embodiment of the present utility model.
In stage performance, sound is a kind of important expression way for expressing the story of a play or opera introduction, elucidation of the theme, such as performer's sound of speech, song
Hand singing sound, background sound music, the footsteps etc. of dancer.When the story of a play or opera is nervous or high water time, sound rhythm can tend to it is close,
Loudness can increase；When the story of a play or opera is more gentle, sound rhythm can tend to releive, loudness reduces.In a word, different pictures, difference
Scene can be expressed by the rhythm and loudness of sound.The utility model is exactly the rhythm and loudness by identifying sound
Characteristic, realize that control light of stage carries out the adaptive adjustment of color, brightness effects with the development of the story of a play or opera.
As shown in figure 1, it is that the adaptive lamp light control system one of the present utility model based on stage set sound is preferred
The circuit theory diagrams of embodiment.There is sound acquisition module 1, signal condition mould in the adaptive lamp light control system of the present embodiment
Block 2, peak detection module 3, square wave generation module 4, frequency measurement meter module 5 and control module 6, the output of sound acquisition module 1
The input of end connection Signal-regulated kinase 2, the output end of signal conditioning circuit 2 are respectively connecting to peak detection module 3 and side
The input of ripple generation module 4, the output end of peak detection module 3 are connected to the input of control module 6, square wave generation module
The input of control module 6 is connected to after 4 output end one frequency measurement meter module 5 of connection.
Sound acquisition module 1 obtains the electric signal that stage set sound converts first, and it can be miaow head, tone frequency channel wire
Any one in joint, audio file reading device or this several combination.Wherein, audio file reading device is
The reading device for the electric signal that the stage set sound conversion of read/write memory medium (such as USB flash disk, TF card) memory storage comes.
The electric signal that signal conditioning circuit 2 obtains to sound acquisition module 1 is nursed one's health, and is filtered out noise and is amplified.This reality
Apply in example, it includes amplifying circuit 21 and filter circuit 22.Amplifying circuit 21 connects sound acquisition module 1, and sound is obtained
The electric signal that module 1 obtains is amplified to default OK range, electricity after the filter circuit 22 being connected with amplifying circuit 21 will amplify
Noise in signal is filtered out, and it is preferably low-pass filter circuit.Preferably, amplifying circuit 21 is adaptive amplifying circuit,
It can automatically adjust multiplication factor, and electric signal is amplified into default scope.
Peak detection module 3 connects Signal-regulated kinase 2, and it has peak holding circuit 31 and a/d converter 32, peak
Value holding circuit 31 is connected with filter circuit 22, and 22 filtered electric signal of filter circuit is carried out into peak holding, AD (analog)
Converter 32 is connected with peak holding circuit 31, the size for the peak value that collection peak holding circuit 31 is kept, size reaction dance
The loudness of platform scene sound.
Square wave generation module 4 connects Signal-regulated kinase 2, by the default fixed width of 22 filtered electric signal of filter circuit
The direct current signal of value is compared, and draws square-wave signal, that is, is high electricity when the amplitude of electric signal is more than the fixed amplitude after filtering
It is flat, it is otherwise low level.Certainly, in order to when filtered 22 filtered electric signal of circuit reaches the 4 of square wave generation module
Still have compared with high s/n ratio, can be filtered again, being filtered can use the signal with filter circuit to adjust again
Reason module 2 is individually added into filter circuit again, and filtered electric signal is handled into square wave generation module 4 again.
Frequency measurement meter module 5, square wave generation module 4 is connected, count the frequency of above-mentioned square-wave signal, i.e. square wave in the unit interval
The number that square wave occurs in signal.Frequency measurement meter module 5 can be realized by frequency measurement meter.The frequency response stage set sound it is fast
Slow rhythm.
Control module 6, frequency measurement meter module 5 and peak detection module 3 is connected respectively, according to the frequency and tune of square-wave signal
The size of electric signal after reason, to adjust the color of light of stage and brightness.Specifically, first by the frequency and tune of square-wave signal
The fusion value of electric signal after reason is divided into default section by size, and each section corresponds to a kind of color, then according to fusion
The residing section of value, produce control instruction and cause light of stage to be in color corresponding to the section, and the brightness of light of stage
Respectively in each section, increase as result increases, reduce as result reduces.Wherein, under fusion value passes through
State formula and calculate gained：
Result=α * rhythm+ (1- α) * volume
In formula, result is fusion value, and α is default fusion coefficients, and rhythm is the frequency of square-wave signal, and volume is
The size of electric signal after conditioning.
In the present embodiment, fusion value result is divided into three sections by two threshold value first thresholds and Second Threshold,
If result is less than first threshold, control module produces is changed into cool colour by the color of lamp；If result is more than Second Threshold,
Control module produces is changed into warm colour by the color of lamp, if result is more than first threshold and is less than Second Threshold, control module
Produce the color that the color of lamp is changed into middle tone, i.e., other colors in addition to cool colour and warm colour.Such can is for difference
Stage set atmosphere, give different light of stage (color and brightness).
After control module produces the brightness of control light and the instruction of color, sent out by connected signal transmitting module
To see off, the signal receiving module of stage lighting receives above-mentioned instruction, and lamp effect control module performs above-mentioned instruction, color to lamp,
Brightness is regulated and controled.Signal transmitting module and signal receiving module can be all wired and communication module of wireless protocols, than
It is such as RS232 communication modules, RS485 communication modules, RS422 communication modules, SPI communication module, IIC communication modules, bluetooth lead to
Believe any one in module, Zigbee communication module and NRF communication modules.
Embodiment of the present utility model is described above in conjunction with accompanying drawing, but the utility model is not limited to
The embodiment stated, above-mentioned embodiment is only schematical, rather than restricted, this area it is common
Technical staff is not departing from the utility model aims and scope of the claimed protection situation under enlightenment of the present utility model
Under, many forms can be also made, these are belonged within protection of the present utility model.
