Dual-redundancy dispatching control system for aircraft alarm computer

Abstract

The invention provides a dual-redundancy dispatching control system for an aircraft alarm computer. The dual-redundancy dispatching control system is characterized by comprising two platforms A and B, wherein each platform mainly comprises an input driving module, a control module and an output driving module, the control module is in interaction with a bus through a discrete IO port, an input acquisition module is used for acquiring discrete and bus alarm information, the control module is used for processing the alarm information according to a certain alarm logic, the output driving module is used for outputting the discrete and bus alarm information, and the control module is used for giving out a self-inspection signal, detecting whether faults occur in the input acquisition module and the output driving module or not and backwards reading according to a self-inspection backward-reading signal. The control module detects whether the fault occurs in the control module or not through self inspection and is in periodic communication with the other platform through synchronous information interaction with the IO port and bus interaction according to the acquired alarm information, and thus, the problems of not-in-time switching, inconvenience in fault diagnosis and recovery and low reliability in the prior art are solved.

Description

technical field [0001] The invention relates to an aircraft warning computer, in particular to a dual-redundancy scheduling control system used by the aircraft warning computer. Background technique [0002] The light warning computer is an indispensable key component of the aircraft light warning system. As the key equipment for aircraft warning, the warning computer's reliability and safety will directly affect flight safety. [0003] The working environment of electrical equipment on aircraft is usually relatively harsh. During the flight, there are always vibrations and shocks, as well as adverse factors such as electromagnetic interference. Poor working conditions increase the failure rate of the light warning computer, which directly affects the flight safety of the aircraft. Therefore, how to effectively improve the reliability of the system is particularly necessary. [0004] At present, in order to improve the reliability of the system, the alarm computer on the...
