1553B data bus testing simulation system

Abstract

The invention discloses a 1553B data bus testing simulation system and belongs to the testing technical field of simulation tests. The 1553B data bus testing simulation system is characterized in that a simulation controller [1], a data transmission and control bus [2], a 1553B communication interface [3] and a 1553B interface adapter [4] form a 1553B data bus simulation and testing environment, and the simulation controller [1] controls the 1553B communication interface [3] through the data transmission and control bus [2] to achieve transmission and receiving of data information, simulates generation and transmission processes of information streams of airborne devices including an airborne flying control system and an avionics system and receives and displays the information streams of other airborne devices. The 1553B data bus testing simulation system is complete in function, reasonable in layout, compact in structure, reliable in working and convenient to use and has good expandability and clipping property.

Description

technical field [0001] The invention relates to a 1553B data bus test system, in particular to the process of generating, transmitting, processing and displaying the information flow of airborne equipment such as simulating avionics systems and flight control computers, and belongs to the technical field of test and test. 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, another important wa...

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, which is not universal. After the state of the flight control system and other components of the 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
