Detailed description of the invention
The invention will be further described with the following Examples.
The present invention judges detection equipment and the detailed description of the invention of its detection method used whether product crystallize, the present embodiment is mainly used in the production process of noncrystalline product, for judging noncrystalline product whether crystallization, if crystallization, then judge that product is defective, to this end, the sound wave that the present embodiment uses the product of amorphization to produce when clashing into is standing acoustic waves.Certainly, in other embodiments, such as need crystalline product as in the production process of qualified products, it is also possible to the sound wave produced when clashing into crystalline product is standing acoustic waves.This detection equipment includes:
Sound generating apparatus: clash into or shake product to be detected, makes band detection product send sound wave to be measured；
Voice collection device: gather described product to be detected and send sound wave to be measured, and it is sent to analytical equipment after sound wave is converted into the signal of telecommunication；
Analytical equipment: as it is shown in figure 1, perform following method step by software program:
Step A: obtain the material property data of product to be detected, carries out vibrations simulation and obtains intrinsic vibration data, by material property market demand to intrinsic vibration data, thus obtain the inherent feature parameter of standing acoustic waves product to be measured.Owing to material, the structure of product are different, therefore the product sound wave produced when being knocked when amorphization is the most different, therefore, for different products, need to predict the inherent feature parameter of the standing acoustic waves of product according to the material of product, certainly, except the prediction at initial stage, the later stage can also carry out adjustment repeatedly according to actual test result to the inherent feature parameter of standing acoustic waves.
Step B: obtain the acoustic signals to be measured that voice collection device sends, extract the inherent feature parameter in sound wave, as in figure 2 it is shown, inherent feature parameter includes following parameter: ED parameter refer to the wave amplitude of sound wave to be measured reach initial value and drop into below initial value for the last time for the first time between time span；Described RC parameter refers to that the wave amplitude of sound wave to be measured strides across the number of times of initial value；Described PA parameter refers to the maximum amplitude of sound wave to be measured；Described RT parameter refers to the time span that sound wave wave amplitude to be measured reaches for the first time initial value and wave amplitude reaches between maximum amplitude；Described PD parameter refers to that sound wave to be measured reaches maximum amplitude and the time span reached between time big wave amplitude.
It should be noted that in commercial Application, according to concrete product attribute, can only select the part in above inherent feature parameter to be analyzed, it might even be possible to analyze only with an inherent feature parameter.The present embodiment is in order to make analysis result as far as possible；Accurate and applicable product as much as possible, therefore have employed multiple inherent feature parametric synthesis and judges.
Step C: inherent feature parameter corresponding with standing acoustic waves respectively for each inherent feature parameter of sound wave to be measured is compared, judge the inherent feature parameter of sound wave to be measured respectively with the deviation ratio (ratio of the inherent feature parameter of the inherent feature parameter drift-out standing acoustic waves of sound wave the most to be measured) of the inherent feature parameter of standing acoustic waves, if deviation value is less than preset value, meeting similarity requirement to this inherent feature parameter inherent feature parameter corresponding with standing acoustic waves judging this sound wave to be measured, i.e. both are similar.
Certainly, for some inherent feature parameter, it would however also be possible to employ inherent feature parameter deviation value with the inherent feature parameter of standing acoustic waves respectively judges, and does not use deviation ratio.
Step D: meet the quantity of the inherent feature parameter that similarity requires in counting step C, if meeting similarity requirement more than 3 inherent feature parameters, then judge that this sound wave to be measured is similar to standing acoustic waves, due to the present embodiment use amorphization product clash into time produce sound wave as standing acoustic waves, therefore may determine that this product to be detected falls within amorphization product, belong to qualified products.Certainly, the requirement such as fruit product is stricter, it is also possible to require that all inherent feature parameters just judge that this sound wave to be measured is similar to standing acoustic waves in the case of all meeting requirement.
Step E: if judging in step D that this sound wave to be measured is similar to standing acoustic waves, then being added to after this sound wave to be measured former is multiplied by weight coefficient with certain weighted value be superimposed to original standing acoustic waves by meeting the inherent feature parameter (can also be all of inherent feature parameter) of similarity requirement in this sound wave to be measured, wherein weight coefficient is adjusted according to the quantity of the most superimposed sound wave to be measured.
Finally should be noted that; above example is only in order to illustrate technical scheme; rather than limiting the scope of the invention; although having made to explain to the present invention with reference to preferred embodiment; it will be understood by those within the art that; technical scheme can be modified or equivalent, without deviating from the spirit and scope of technical solution of the present invention.
