Fault management method based on XML language

Abstract

A fault management method based on an XML language comprises the steps: defining an XML file format, wherein the XML file format comprises a root node and a plurality of child nodes, and each child node is used for describing one piece of fault information and comprises three elements including a fault identification code, fault description and a fault solution; using an associated container to manage a fault, binding the XML file to a standard file format, and storing the XML file in a memory; analyzing node information of the XML file, obtaining detailed information of each fault, and storing the detailed information into an associated container; creating a fault matching thread, and obtaining fault description and fault solution information in the associated container according to the fault identification code sent by the bus; and establishing a standard data model class, combining the standard data model with a display list, wherein each row of the display list corresponds to a fault, and when a new fault is received, a fault row is added in the display list, and new fault information is displayed. According to the method, under the condition that the source code is not changed, the fault list can be added, modified and deleted, compiling is not needed, and the operation efficiency is not influenced by adding the fault information.

Description

technical field [0001] The invention belongs to the field of aerospace system data communication, and relates to a fault management method based on XML language. Background technique [0002] Aerospace systems are large-scale systems with multi-node characteristics, and each node is a complete small system. Therefore, fault management in the system is a particularly important link. The traditional fault management method is usually for each subsystem to perform fault management separately. It is carried out by recording log files, and the failure of aerospace equipment needs to be diagnosed and analyzed after the equipment returns to the ground, which greatly increases the risk and cost of failure management. [0003] In the fault management of aerospace systems, the usual method is to compile the fault identification code into the program in the form of code, and use the file record method to store the fault identification code in the log file where the subsystem fails, whi...

Problems solved by technology

[0003] In the fault management of aerospace systems, the usual method is to compile the fault identification code into the program in the form of code, and use the file record method to store the fault identification code in the log file where the subsystem fails, which is limited to hardware Resources usually only store fault identification codes. Generally, it is necessary to manually correspond to the fault information according to the fault identification code after checking the record file. The disadvantages of the traditional processing method include that adding, deleting, and modifying a fault code need to be recompiled. Aerospace systems sometimes even require joint compilation of different systems. At the same time, due to the limited memory space of the system, compiling a large amount of fault information into the source code affects operating efficiency
