A kind of arinc429 data bus emulation test system

Abstract

An ARINC429 data bus simulation test system belongs to the technical field of simulation test. It is characterized in that the ARINC429 data bus simulation and test environment is formed by the simulation controller [1], the data transmission and control bus [2], the ARINC 429 communication interface [3] and the ARINC 429 interface adapter [4], and the simulation controller [ 1] Through data transmission and control bus [2] control ARINC429 communication interface [3] to realize the transmission and reception of data information, simulate the generation and transmission process of information flow of airborne equipment such as airborne flight control system and avionics system, and receive Other airborne equipment information flow and display. The invention has the advantages of complete system function, reasonable layout, compact structure, reliable operation, convenient use, good expansibility and tailorability.

Description

Technical field [0001] The invention relates to an ARINC429 data bus simulation test system, in particular to the generation, transmission, processing and display process for simulating the information flow of airborne equipment such as avionics systems and flight control computers, belonging to the technical field of simulation tests. Background technique [0002] Airborne equipment such as flight control systems and avionics systems are becoming more and more important in the design process of modern aircraft. With the application of fly-by-wire flight control technology, active control technology and information processing technology, flight control systems and avionics systems have reached the level of At the same time, the safety and reliability of the flight control system and avionics system are more important to the safety of the aircraft. In order to ensure the safety and reliability of the flight control system and avionics system On the basis of the design, anothe...

AI Technical Summary

Problems solved by technology

[0004] (1) The installed equipment can only be produced and provided after the design of the flight control system is completed, which cannot meet the needs of the design and development stage test or the initial prototype stage test;

[0005] (2) The installed equipment is developed and produced for a special flight control system and is not universal. After the status of other components of the flight control system and avionics system changes, it needs to be adapted, or even reprocessed and produced.

[0006] (3) The installed equipment is completed by manual operation, the verification test process is inefficient and the cycle is long;

[0008] (5) The research of the real system is not only time-consuming and costly, but also costly, risky, and long-term, and it is difficult to do it. Using computer simulation technology can simplify the complexity and greatly save manpower and material resources

[0009] At present, most of the domestic and foreign studies on flight control system and avionics system data information transmission simulation are aimed at a certain stage of flight control system and avionics system structure data flow transmission or processing, only for a certain aspect of system information interaction, and for flight control systems and avionics systems. Systematic and comprehensive evaluation and analysis of the performance of control systems and avionics systems has certain limitations
