Problems solved by technology

With the continuous improvement of communication speed and reliability requirements of avionics products, FC-AE-ASM has been widely used in various models. At present, the analysis of FC-AE-ASM data is mostly embedded in the special test system of each product. There are two main problems: one is that the interface data analysis methods cannot be shared between test systems of different products, and analysis codes need to be written separately for different interface control files, which reduces the reusability of the test system; When the control file changes, it is necessary to redevelop the interface data analysis method of the test system, which reduces the test efficiency and reliability of the test system

Embodiment Construction

[0056] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further elaborated below.

[0057] Fiber Channel Aviation Environment (FC-AE) is a family of protocols developed by the Fiber Channel Standards Development Organization. The FC-AE-ASM protocol is an upper-layer protocol in the FC-AE network. This protocol is used to support the Fiber Channel avionics environment. Deterministic, secure, and low-latency communication between various processors, sensors, and displays in the system. The invention includes an interface control file database conversion method and a data analysis method, and can be applied to all product automatic test systems containing FC-AE-ASM data.

[0058] Such as figure 1 The message name table field description diagram shown:

[0059] Create a "message name" table, which includes "message number", "message name", "element signal name", and "eleme...

Abstract

The invention relates to a general FC-AE-ASM data analysis method based on product interface control files. The general FC-AE-ASM data analysis method comprises an interface control file database conversion method, wherein the database conversion method comprises the steps of data type partitioning, general message name table creating, data information table creating and discrete signal table creating; and a data analysis method, wherein the data analysis method comprises the steps of structure array creating, MsgID reading, MsgID and message number field comparing, data length acquiring according to element types, discrete signal data value acquiring and data signal data value acquiring. The eneral FC-AE-ASM data analysis method can be applied to an automated testing system for all products containing FC-AE-ASE data and is high in generality; and when the product state changes, only corresponding content of an interface control file database needs to be changed, and no influence can be caused on the automated testing system.

Description

technical field [0001] The invention relates to the technical field of FC-AE-ASM bus testing, in particular to a general parsing method for FC-AE-ASM data based on product interface control files. Background technique [0002] The interface control file is the core of avionics products. In order to realize product testing and fault diagnosis, it is necessary to analyze the monitoring data of the product interface based on the interface control file. With the continuous improvement of communication speed and reliability requirements of avionics products, FC-AE-ASM has been widely used in various models. At present, the analysis of FC-AE-ASM data is mostly embedded in the special test system of each product. There are two main problems: one is that the interface data analysis methods cannot be shared between test systems of different products, and analysis codes need to be written separately for different interface control files, which reduces the reusability of the test syste...
