Background technology
The design of Most current music running lamp is all to allow running lamp follow the sound intensity change of music to change, as extensively
Field music fountain, although good-looking, but the sympathetic response of people can not be caused.People, when listening music, can automatically identify rhythm, and then
Hired roughneck claps together.And we are when dancing hall or karaoke halls are sung, the audience also liking following can follow rhythm to applaud.But thing
In the real upper most of the time, the rhythm of music is not struck a chord by audience, or no one takes the lead and then rhythm applause.Cause
This, be sought after a kind of device that can automatically identify music rhythm, and automatically follows the speed change of rhythm and the intelligent sound that flashes
Happy LED running lamp so that in dancing hall or karaoke halls, music combines together completely with the change of environment.
Summary of the invention
In order to solve above-mentioned the deficiencies in the prior art, it is an object of the invention to provide a kind of intelligence based on music rhythm identification
LED running lamp and its control method.
To achieve these goals, a kind of based on music rhythm identification the intelligent LED running lamp designed by the present invention, bag
Including music rhythm identification system and running lamp control system, described music rhythm identification system includes the envelope detector of electrical connection
With low pass filter, forming envelope signal for filtering the high-frequency components in audio signal, described running lamp control system includes
Single-chip microcomputer, comparator and bin, described single-chip microcomputer is for receiving the envelope signal that low pass filter is formed, and believes envelope
Number contained energy and phase place are analyzed, so that it is determined that the start position of stress and rhythm in audio signal, and by stress
Start position and rhythm form signal and are transferred in comparator, and for receive comparator relatively after information and according to this letter
Breath control running lamp flicker pattern, described comparator for receive single-chip microcomputer output signal and with the style journey in bin
Sequence compares, and the information after comparing is transferred to single-chip microcomputer, and described bin is for storing the flower of various running lamp flicker
Sample program.
Wherein, the start position of the stress that running lamp every kind flicker pattern is corresponding and rhythm form a style program, respectively
The style program planting flicker pattern corresponding is stored in bin, for controlling the flicker of running lamp.
Preferably, described single-chip microcomputer model is AT89C51.
The control method of intelligent LED running lamp based on music rhythm identification in the present invention, comprises the following steps:
(1), music rhythm identification system reads the audio signal in music, and through envelope detector and low pass filter, filters
Fall the high-frequency components in audio signal and form envelope signal, and envelope signal is transferred to single-chip microcomputer；
(2), single-chip microcomputer reads envelope signal, and is analyzed the energy in envelope signal and phase place, so that it is determined that audio frequency is believed
The start position of stress and rhythm in number, and form corresponding signal and be transferred to comparator；
(3), comparator receive the signal of single-chip microcomputer transmission and compare with the style program of bin, and comparative result is anti-
Being fed on single-chip microcomputer, when comparative result matches, single-chip microcomputer is carried out according to this style program according to this output control running lamp
Flicker；
(4), when comparative result does not mates, Single-chip Controlling running lamp flashes according to the program preset, and the most single
The audio signal of music rhythm identification system subsequent read is analyzed by sheet machine, until with the style program in bin mutually
Timing, Single-chip Controlling running lamp flashes according to this style program.
Compared with prior art, the invention has the beneficial effects as follows: running lamp can be according to the change of the music rhythm play
Changing, the flicker style that adaptive formation is different, thus cause the sympathetic response of people, making the change of music and environment melt completely is one
Body.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the present invention.
Detailed description of the invention
The present invention is further described with embodiment below in conjunction with the accompanying drawings.
As it is shown in figure 1, a kind of based on music rhythm identification the intelligent LED running lamp that the present invention provides, including the Music Day
Playing identification system and running lamp control system, described music rhythm identification system includes envelope detector 1 and the low pass of electrical connection
Wave filter 2, forms envelope signal for filtering the high-frequency components in audio signal, and described running lamp control system includes single-chip microcomputer
3, comparator 4 and bin 5, described single-chip microcomputer is used for receiving the envelope signal that low pass filter is formed, and to envelope signal
Contained energy and phase place are analyzed, and use the similar synchronized algorithm in communication, by repeatedly comparing, so that it is determined that audio frequency
The start position of stress and rhythm in signal, the start position of stress is i.e. initial phase, and rhythm is i.e. adjacent stress in note
Average time between position, is also period of change or the frequency of envelope signal, and is formed with rhythm by the start position of stress
Signal is transferred in comparator, and for receive comparator relatively after information and according to the sudden strain of a muscle of this information control flow water lamp 6
