Description
Technical Field
The invention relates to an avionics communication module failure analysis report automatic guiding and filling tool with a communication function.
Background
Failure analysis is a new developing discipline, which relates to a wide range of discipline fields and technical categories, and process potential failure modes and impact analysis (PFMEA) is a systematic activity that analyzes subsystems and parts forming a product one by one in a product design stage and a process design stage, finds out all potential failure modes and analyzes possible consequences thereof, thereby taking necessary measures in advance to improve the quality and reliability of the product. FMEA begins before product design and manufacturing process development activities and guides are performed throughout the product cycle. The method is a kind of induction analysis method which analyzes all possible failure modes of each product in the system and all possible influences on the system, and classifies the failure modes according to the severity of each failure mode, the detection difficulty and the occurrence frequency. The FMEA contributes to the initial design of manufacturability and assembly, contributes to the objective and real evaluation of design requirements and different designs, provides correct and appropriate basis for making a test plan, provides an ordered list of failure modes, and establishes a priority control system for improving design and developing tests to carry out quantitative FMEA risk assessment, cause/mechanism listing and prevention/improvement measure finding. The analysis standard FMEA of the potential failure mode and the consequences is used for carrying out DFEMA analysis on each module and a software system of a product before the product is designed, such as structure installation, safety design, movement matching, external interfaces and the like, and can also be refined to each component. Analysis object PFMEA (manufacturing/assembling FMEA) which is an analysis object of a system, a subsystem or a part, and is used for analyzing the production and manufacturing process of a product. The risk and loss are reduced by analyzing what failure modes and what impact consequences may occur during the production process and detecting or preventing failure propagation, and the reliability of the product is improved.
The failure analysis of the avionic communication module is to analyze failure modes and influences of the avionic communication module, and the basic principle is to find out all potential failure modes according to the physical composition of a functional circuit of the avionic communication module and by combining the signal transmission relation in the module and the signal input and output relation between the module and the outside and analyze the influences possibly caused by the failure modes. The failure mode and influence analysis report form filling of the communication navigation identification module is a behavior process of outputting a report form file containing the failure mode and influence analysis information after the potential failure mode and influence analysis aiming at the composition module of the electronic system by related personnel. The basic principle of the report filling tool is that according to the failure mode and the influence actual content analyzed by a circuit designer and according to the failure mode and the influence analysis principle determined by a sextual designer, a normalized report file meeting the industrial standard is output in an auxiliary mode.
The avionics communication module is a general term for an electronic module which is specially used for avionics and has a communication function. The avionic communication module is a main component of an avionic task system, and along with the increase of functions of the avionic task system, the avionic task system is increasingly huge in composition, the avionic communication module is increasingly difficult in mechanism, and the signal cross-linking relationship is increasingly complex. The failure mode and the influence analysis report form of the avionic communication module are filled and reported only by manpower, the execution process is complicated and time-consuming, the accuracy of the execution result is low, and the requirements of testability design, optimization and review cannot be met. Therefore, the method has become an important support in the current comprehensive guarantee process of the whole life cycle of the electronic equipment and has emerged a plurality of derived software reporting tools for analyzing the failure mode and the influence of a large-scale electronic equipment module, particularly an avionics communication module in an avionics task system and completing report form reporting work.

The method has the characteristics of artificial dependence and experience dependence in the process, so that the filling process is lack of intelligent degree, various complex communication navigation identification modules are formed in the current large-scale electronic system, and the requirements of testability design, optimization and evaluation are difficult to be intelligently completed at low cost, which is the improvement of the filling tool.
Secondly, the automation degree of the filling process is low. And in the filling process, standardized manual filling is carried out according to the failure mode and the influence result which are obtained by analyzing the analyzed module by a professional. The existing domestic filling tool is mainly used for standardizing filling and verifying filling results, but the filling process still depends on manual input, the automation degree of the whole filling process is low due to the design key point, and the whole filling efficiency is low when various complex communication navigation identification modules are formed in a current large-scale electronic system, which is the key for mainly promoting attention.
Thirdly, the professional pertinence of the filling content is weak. The failure analysis report form filling tool in China at present is mainly designed aiming at a universal module, and is not divided according to fields and combined with professional knowledge. Therefore, in the filling process, the problem of insufficient professional pertinence generally exists, the correctness of filling contents is greatly influenced, and the important focus is also on solving the problem.
In order to solve the problems in the avionic communication module failure analysis report form filling tool, the avionic communication module failure analysis report form filling tool is designed with the aims of improving the intelligent degree and the automation degree and enhancing the specialty in the avionic communication module failure analysis report form filling process, and has the characteristics of more intelligent process, more efficient execution and more correct content.
