摘要

Purpose. Enhancing the protection of automated ground robotic platforms in the conditions of threats of the electromagnetic spectrum by implementing the developed mathematical model of the reliability of information processing and control systems in the system of residue class. Methodology. The research applies non-traditional methods for increasing the reliability of information processing for ground robotic platforms based on the use of system of residue class codes. The process of creating a reliable mathematical model of the information processing and control systems functioning in the non-positional numeral system in the residue class has been researched. The work used a complex of research methods, which includes the theory of reliability and the theory of interference-resistant coding in the system of residue class. The research is based on the methodology of data reservation of non-positional code structures, which provides for the simultaneous presence of three types of reservation: structural, informational, and functional ones. Findings. Calculations and a comparative analysis of the reliability of information processing and control systems are provided, namely, fault tolerance according to the indicator of the probability of failure-free operation of the triplicated majority positional (binary) system and system synthesized on the basis of codes of the system of residue class, which is 0.96724 and 0.99986, respectively. It was proved that the information processing and control system operating in the system of residue class with one reserve computational path and a reliability automaton has better reliability indicators than the triplicated positional structure, taking into account the influence of the majority element. The results of calculations of the amount of equipment required for the implementation of the considered model show that the gain is 4, 27, 38 and 42 % for one-, two-, three- and four-byte bit grids; it leads to a decrease in hardware costs, price and energy consumption of the system, which is extremely important for ground robotic platforms. Originality. A reliable mathematical model is proposed, which, under the condition of using functional data reservation in non-positional code structures, differs from analogues in the possibility of replacing one or more inoperable information tracts with a control one. This allows us to consider information processing and control system as a highly reliable system with dynamic reservation without stopping the computing process, which is a rather important parameter for ground robotic platforms operating in real time. Practical value. The proposed solution can be used to create highly reliable information processing and control systems of robotic platforms. The use of the proposed model will increase survivability and resistance to threats of the electromagnetic spectrum of the robotic platform and ensure a high level of its protection in the conditions of increased radio-electronic warfare. The practical application of the proposed model, especially with an increase in the bit grid of information processing systems, leads to a significant reduction in the amount of necessary equipment, which will enable developers to balance cost and quality, provide the necessary functionality with specified reliability indicators, and also create a robotics platform that meets modern requirements and standards.
