INVESTIGATION OF THE SIMULATION MODEL OF MEASUREMENT SIGNALS SAMPLING WITH RESPECT TO THE MINIMUM ERROR OF INFORMATION RECOVERY

Abstract

Further ways of improving the system of control and diagnostics of the technical condition of radio electronic systems of water transport means during its operation are substantiated. It is proved that the existing methods and technologies underlying the construction and operation of technical control and diagnostics of radio electronic systems are not very effective. The reason for this is the extremely difficult conditions of functioning of water transport means, the ever-increasing complexity of radio electronic systems, which themselves and the technical control and diagnostic means serving them use analogue, analogue-digital and digital signals, which does not correspond to advanced approaches to the construction of modern systems and complexes. Possible ways to achieve the required characteristics of technical control and diagnostic means in water transport are to obtain and process diagnostic information from various analogue and digital radio electronic systems, improve the principles of functioning of technical control means of radio electronic systems and ensure minimal error in information recovery when sampling measurement signals. The aim of the work is to study the simulation model of measurement signal sampling with respect to the minimum information recovery error. The paper investigates the errors of information recovery of technical control and diagnostics of radio electronic systems of water transport means at the stage of operation. It is proved that the difference in the sampling rate from the optimal one causes the loss of information about the input signal. The sampling rates less and more than the optimal one is investigated and the errors, causes and volumes of loss of information about the input signal, as well as the influence of interference in the output signal are analysed.
