Abstract

Article is devoted working out of program models of the communication channels in Simulink. Models are intended for the analysis of reliability of an information transfer by preparation and start-up of rockets of space appointment as processes of updating and re-equipment of starting complexes demand support of high quality of the information exchange, considering features of functioning of the automated systems of preparation and start-up.

At construction of communication channels models in Simulink library Communications System Toolbox blocks, and also blocks of subsection Ports&Subsystems have been used, allowing to model a feedback and the duplicated channel by means of such algorithmic designs, as a cycle with a postcondition and conditional transition.

The program model of the communication channels with a solving feedback in Simulink is developed, allowing to analyze reliability of an information transfer with application of the codes which are finding out errors. The program model of the duplicated channel of an information transfer with a solving feedback in Simulink is developed, allowing to analyze reliability and a continuity of process of an information transfer.

The developed models can be used for formation of statistical data necessary at an estimation reliability of an information transfer and definition of dependence of values of indicators of reliability from parameters of a transferred file, characteristics of the channel with noise, algorithms of coding and decoding.

The offered models are intended for carrying out of computer experiments within the limits of educational process and research work, and also for perfection of knowledge in the field of the theory of an information transfer and skills of modeling of information-operating systems.
