Problems solved by technology

[0006] At present, most of the ARINC429 bus signal simulation test programs used in avionics systems only realize the basic communication performance test of the ARINC429 bus, and do not perform simulation tests on the physical quantity (ie engineering value) parameter value of the ARINC429 data for specific ICD requirements; or It only makes special test software for the ICD of a specific avionics equipment, but does not form a general ARINC429 signal simulation test program for ICD and configurable signals

Embodiment Construction

[0035] The present invention will be described in detail below in conjunction with the accompanying drawings. The ARINC429 bus signal simulation test component is developed based on the .NET Framework platform, uses C# language, and adopts object-oriented signal description and .net component design ideas. The working principle and data flow of the component are shown in the box figure 1 .

[0036] The implementation steps of the .net component are as follows:

[0037] 1. The constructed ARINC429 bus data model uses a set of classes to implement the ARINC429 bus data description method. The logical structure of this set of classes is as follows figure 2 .

[0038] (1) ARINC429 channel class

[0039] The main fields are: channel baud rate, channel number, channel name, cyclic sending period, word check type. This class contains a list (List) of "ARINC429 data words", and the number of ARINC429 data words in this channel is the number of data words in the List.

Abstract

The invention belongs to a simulation test technology and relates to an ICD-oriented ARINC429 bus signal simulation test assembly applied to the technical field of avionics. A group of basic signal class libraries according with an ARINC429 standard are defined, a standard model of an ARINC429 bus signal is built, a simulation signal configuration file is generated after a user records ICD information, configuration file data of the ARINC429 bus signal are stored by adopting a file in an XML (Extensible Markup Language) format; an ARINC429 bus reads the configuration information of a signal configuration file, a corresponding ARINC429 signal control is loaded, a parameter engineering value is set on a simulation output interface of the ARINC429 bus signal and is automatically solved into an ARINC429 source code value according to the configuration information of the signal configuration file, data are packaged and transmitted to an ARINC429 board card driving layer interface, and a driving instrument outputs a simulation signal.

Description

technical field [0001] The invention belongs to the simulation test technology, and relates to an ICD-oriented ARINC429 bus signal simulation test component applied in the technical field of avionics. Background technique [0002] ARINC429 communication technology is widely used in various aircrafts, and it is a relatively commonly used data communication bus. [0003] ICD (Interface Control Document) interface control file, which describes the definition of the bus data of the avionics system, including the physical layer and logical link layer of the system, the meaning of the physical quantity parameters of the data, the proportional relationship, the unit of the physical quantity, the coding form, the fault code, etc. various information. [0004] Component technology is a further development of object-oriented technology, which encapsulates internal details and connects with other components through interfaces. .NET component is a new generation component technology o...
