| Abstract [eng] |
The principal of works means and reception of the solution, used for the investigation of rails flaw do not change. Even the newest microprocessor systems of rails’ flaw detection which is found in the latest year uses the simplest criteria’s, that are the amplitude of the reflected ultrasound signal and delaying time. While computer and microprocessor technology improves, the means of numerical measurement and possibilities of processing data, that is signals capable to measure the large majority of the more difficult structure and the algorithm or functions, are found out. The widest classification of the objects is used for identifications’ solution based on separating random processes. The acoustic diagnostic of engines and mechanics, sound and ultrasound defectoscopy, and objects’ identification in accordance with spread signals’ of noise that are in the random background and etc. are named in all those areas where the method of random processes’ classification is suitable. |
