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 present invention relates to the general analysis method of FC-AE-ASM data based on the product interface control file, including the interface control file database conversion method, the data analysis method, the database conversion method includes the steps of dividing the data type, establishing the general list of message names, and establishing data information Table, establishment of discrete signal table, data parsing method, including steps: establishing structure array, reading MsgID, comparing MsgID and message number field, obtaining data length according to element type, obtaining discrete signal data value, obtaining data signal data value. The present invention can be applied to all product automatic test systems containing FC-AE-ASM data, and has strong versatility; when the product state changes, only the corresponding content of the interface control file database needs to be changed, and the automatic test system will not be affected.

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...
