Description
Technical field
The present invention relates to machinery noise reduction technology field, particularly relate to a kind of textile machine against sound noise-reduction method.
Background technology
Textile machine is exactly that natural fiber or chemical fibre are processed into the various plant equipment required for textile.Just
It is quickly to develop due to textile machine to be just satisfied the life requirement that people improve constantly.Existing textile machine is no longer only
For dress ornament, but occur in the life of people with various forms such as carpet, vamp, aircraft wing, spacesuiies, section
On the frontier development of skill.For satisfying social needs and improving product quality, textile machine is generally processed with speed faster,
Cause noise the most unavoidably thus damage the health of machine operator.
By constantly investigating discovery, work the most in a noisy environment and can cause audition, cardiovascular, fecundity
The damage of the aspects such as power, psychiatric system, the intestines and stomach ability, memory.Existing noise-reduction method generally uses antivibrator to carry out high frequency
Offsetting, operator carries earplug etc..But the elimination noise that these measures can not be good, still makes the health of machine operator
Become injury, and be not easy to work.
Summary of the invention
The present invention provides a kind of textile machine against sound noise-reduction method, solves existing textile machine and has what noise was difficult to eliminate
Technical problem.
The technical solution adopted for the present invention to solve the technical problems is: provide a kind of textile machine against sound noise-reduction method,
Comprise the following steps:
(1) sound intensity probe is utilized to learn noise signal in textile machine work process；
(2) it is analyzed noise signal processing, it is thus achieved that the spectrogram of noise；
(3) draw the inverse noise pattern needed for noise reduction according to noise pattern, and carry out analogue simulation, it is thus achieved that section knot
Really；
(4) determine quantity and the position of speaker according to section result, and send inverse noise signal to support by speaker
Eliminated noise.
Described step (2) use MATLAB software be analyzed noise signal processing.
Described step (3) use FEMLAB carry out analogue simulation.
Also include after described step (4) again carrying out acoustical signal collection by sound intensity probe, it is judged that now noise cancellation
Whether result meets the step required, if be unsatisfactory for, then using result as feeding back to correct inverse noise signal.
Described sound intensity probe selects SI512 model.
Beneficial effect
Owing to have employed above-mentioned technical scheme, the present invention compared with prior art, has the following advantages that and actively imitates
Really: the present invention completes noise cancellation by the inverse noise applying noise spectrum reverse, it is achieved reduce in textile machine work process
The job requirement of noise.
Accompanying drawing explanation
Fig. 1 is the flow chart of the present invention；
Fig. 2 is the functional-block diagram of the present invention；
Fig. 3 is the application schematic diagram of the present invention.
Detailed description of the invention
Below in conjunction with specific embodiment, the present invention is expanded on further.Should be understood that these embodiments are merely to illustrate the present invention
Rather than restriction the scope of the present invention.In addition, it is to be understood that after having read the content that the present invention lectures, people in the art
The present invention can be made various changes or modifications by member, and these equivalent form of values fall within the application appended claims equally and limited
Scope.
As depicted in figs. 1 and 2, a kind of textile machine that the present invention provides, against the implementation of sound noise reduction, utilizes the sound intensity to visit
The equipment such as head, speaker, and use MATLAB, FEMLAB etc. to be analyzed and analogue simulation, thus realize the mesh of inverse sound noise reduction
's.
Specifically comprise the following steps that 1, utilize sound intensity probe to learn noise signal in textile machine work process；2, utilize
Noise signal is analyzed processing by MATLAB software, it is thus achieved that the spectrogram of noise；3, noise reduction institute is drawn according to noise pattern
The inverse noise pattern needed, and carry out FEMLAB and carry out analogue simulation, it is thus achieved that result of cutting into slices；4, true according to FEMLAB simulation result
Determine quantity and the position of speaker, and send inverse noise signal；5, acoustical signal collection is carried out by sound intensity probe, it is judged that now
Whether noise cancellation result meets requirement；If be unsatisfactory for, then using result as feeding back to correct inverse noise signal；If met
Then without continuing the inverse noise signal of amendment；Inverse noise signal can be constantly improved until meeting final requirement by this feedback.
As it is shown on figure 3, operator present position is overlapped with noise due to inverse noise in textile machine work process
Comprehensively, thus ensure that operator will not be disturbed by noise, reduce the noise infringement to health, and do not affect its operation.
Owing to the work of textile machine presents cycle movement more, therefore can be by the inverse noise signal under machine steady statue
Carry out record, and improve recording continuous refreshing, until the noise in the cycle eliminates all reaches noise reduction requirement.Therefore can be straight
Connect and will give speaker against noise signal, thus meet the requirement of fast noise reduction.
According to the above description, this textile machine against widely applicable for the more traditional noise-reduction method of implementation of sound noise reduction,
Can not affect machine work, and can guarantee that good processing conditions, to operator's health fanout free region, implementation cost is cheap, complete
One-tenth degree is good.
