The invention relates to a
system fault comprehensive declare
processing method, in particular to a fault comprehensive declare
processing method of a redundancy fly-by-wire flight
control system. The redundancy fly-by-wire flight
control system is composed of subsystems of a flight control computer, a
servo actuator, a sensor, a control display, a built-in self
detector and the like; in order to improve redundancy management information comprehensive capability of the subsystems, default information characteristic quantity of the subsystems are extracted and are composited by using a state matrix mode, fault levels are determined according to fault
modes and number of faults, the
system faults are comprehensively declared, and the fault
modes and the fault levels are indicated through different
modes and equipment, so that pilots can timely know flying state and security status of airplanes. The faults are comprehensively declared by the state matrix mode, the information of the faults is concentrated in one form document, the comprehensive declare information is acquired by searching the file, and accuracy in requirement description and execution efficiency of
software are improved.
