Method for constructing dynamic relevant fault management system of airborne network

Abstract

The invention discloses a method for constructing a dynamic relevant fault management system of an airborne network, and belongs to the technical field of electronic information. The method comprises the following steps: firstly, for a static physical structure of an airborne network system in a certain comprehensive test, constructing a product tree and a topological graph for a texted structure part; then, for a dynamic test process of the airborne network system in the comprehensive test, constructing a test item tree for the texted structure part; establishing a data model RI of the fault management system according to the product tree, the topological graph and the test item tree; then, for arbitrary two fault cases fi and fj in the data model RI, judging and determining the dynamic association information between the two fault cases fi and fj; and finally performing brightness display and storage on the topological graph. By adoption of the method disclosed by the invention, reference is provided for engineering technicians to intuitively discover weak links causing relevant faults easily and belonging business logic paths in the design and troubleshooting of avionics systems, and reference is also provided for purposeful reinforcement and improvement of the system.

Description

technical field [0001] The invention belongs to the technical field of electronic information, in particular to a method for constructing an airborne network dynamic correlation fault management system. Background technique [0002] Airborne network faults not only include the faults reflected by the static network hardware topology; they also include the faults formed by the logical relationship of various applications with avionics business as the process during use. This type of fault behavior presents a strong dynamic dependency and The characteristics of propagation are mainly manifested in the form of dynamics and relevance: the generation of faults is closely related to the path of the test business. If this path is not followed during the test, no faults will occur; The selected service path is propagated to other devices, and network faults with such behavior characteristics are dynamic correlation faults. [0003] Traditional fault management systems such as FMEA,...

Problems solved by technology

Due to the particularity of airborne network failures and the particularity of avionics system integration testing, the dimension of the avionics system airborne network failure case information is essentially different from the traditional fault case information based on the SNMP protocol. The fault information constructed by the electrical integration test fault ticket lacks the timing information of the fault, so these popular modeling and analysis methods for fault dynamics and correlation cannot support the con...
