WAY OF WITHOUT-ETHALON CONTROL OF ON-BOARD COMPUTER SYSTEM OPERABILITY ACCORDING TO IMA CONCEPTION

One of the primary tasks of aerospace instrumentation is the improvement of the onboard computer system in accordance with the concept of integration of onboard equipment IMA. Traditionally, the fail-safety of the on-board computer system is provided by a set of hardware-software methods for detecting, localizing and replacing a failed element by one of the reservation methods. This approach involves the introduction of hardware, time, information or software redundancy into the system. In order to minimize the hardware and information redundancy of the diagnostic and control system, the article offers a standardless control method of the performance of the crate multiprocessor supercomputer. The developed algorithm of the control automaton provides self-diagnostics and fault tolerance of the onboard computer system by its majority-dynamic reconfiguration. The intervals between monitoring sessions are determined by the theoretically predicted uptime of the on-board computer system. The procedure for monitoring, diagnosing and restoring the system's operability consists of four stages: monitoring the system's operational state; determination of the nature of the error detected in the first cycle; localization of the failed processor; restoration of the system with the help of an adaptive algorithm for reallocation the tasks of the failed element between operable processors. The practical significance of the proposed version of the standardless control method of on-board computer system is to increase the avionics survivability in harsh environments characterized by complex climatic, mechanical, electromagnetic, radiation effects at the severe restrictions on the weight and size parameters and power consumption.
