Instruments and Systems: Monitoring, Control, and Diagnostics Annotation << Back Onboard reconfigurable monitoring and diagnostics system of the spacecraft YU.N. KOFANOV, L.V. SAVKIN In article the method of organization control and diagnostic support of spacecrafts on the basis of reconfigurable computing systems is offered. Features of hardware-software creation of the reconfigurable monitoring and diagnostics system of the spacecraft are considered. The skeleton diagram hardware architecture of the onboard reconfigurable monitoring and diagnostics system of the spacecraft constructed as a part of a uniform reconfigurable computing field is provided. Two methods of the organization onboard control and diagnostic support of the spacecraft by means of the reconfigurable monitoring system and diagnostics are probed. The first method consists in the organization of control and diagnostic support for the diagram with the common bus multiplex channel of an exchange without use of independent access to control points of onboard systems. The second method consists in the organizations of control and diagnostic support for the diagram of the built-in monitoring with use of independent access to control points of onboard systems. Possibility of the hardware implementation in a uniform reconfigurable computing field of dichotomizing search trees of failure in case of multi-level hardware diagnosing of onboard systems of the spacecraft by means signature analysis methods is considered. It is shown that the second method together with use signature analysis methods can simplify considerably procedures of multi-level hardware diagnosing onboard systems of the spacecraft.
