Abstract

The invention discloses a method for realizing the same-position replacement of various buses, and belongs to the technical field of aviation airborne buses. The method is used for guiding bus circuitdesign, the bus circuit exhibits universality, flexible reusability and expandability, and one series of circuit design can be replaced. The method comprises the following steps that: 1) selecting abus logic controller; 2) designing various bus driving modules; and 3) designing the internal and external connection relationship of the bus driving module. The method guides to finish developing onetype of bus circuit based on a certain type, the development of the type of bus circuit basically can cover the development of new products which are compatible with the physical structure of the circuit for more than 95% or the transformation of an old product.

Description

technical field [0001] The invention relates to a method for realizing co-location replacement of multiple buses, which belongs to the technical field of aviation on-board buses. Background technique [0002] The bus is an important part of the aviation onboard computer, which undertakes the data exchange task between the computer and the system electronic components (such as steering gear controller, sensor, etc.), avionics system and other electronic components / equipment on board. [0003] Due to the complex and diverse needs of new and old models and different models, the bus board involves different numbers of 1553B, ARINC429, RS422 and other traditional buses and combinations, as well as new AFDX bus, military 1394B bus, TTP bus and other advanced bus technologies. This leads to a wide variety of products, a large number of low-level duplication of labor, increased development costs, and low work efficiency. In order to better adapt to the needs, combined with the char...
