It is offered to use a signal of fluctuations of speed of rotation of a cranked shaft at monitoring of identity of working cycles of the power unit. Hardware has been built and information technology for primary signal processing has been created. A deterministic mathematical model of a diesel circuit in the form of a mechanical system with four degrees of freedom under the condition of friction, Laplace transform, methods of similarity theory and signal graph theory, as well as the method of determinants is used in the development of algorithmic software. The monitoring procedure leads to the solution of a system of redefined algebraic equations with optimization of results based on the method of least squares. Keywords: fluctuation signal, information technology, algorithmic software, Laplace Transform. |
