Abstract

The invention provides a dynamic ICD (Interface Control Document) configured bus simulator system, and aims at providing a bus simulator system which has better extensibility and reusability and high universality. The dynamic ICD configured bus simulator system is realized by the following technical scheme: a display control system and a bus communication system are respectively of independent software for carrying out data communication through DDS (Data Distribution Service) communication middleware; the display control system is used for dynamically generating interface controls through loading interface configuration files, one group of ICD bound controls are automatically traversed, numerical values in the controls are read; automatic packing and unpacking of ICD data items are respectively realized according to a format of a big endian or a little endian; modeling is carried out on a relative layout relation of the interface controls and the controls, and controls capable of being automatically distributed are generated according to a tree-like hierarchical structure of the interface configuration files; retransmission of data between two types of bus drives is realized through the bus communication system; transmission and receiving of bus data and analysis and generation of the bus data are decoupled through the DDS communication middleware and a bottom-layer driver.

Description

technical field [0001] The invention relates to a bus simulator system mainly used in joint test occasions of avionics equipment. Background technique [0002] With the development of information technology and computer technology, bus technology has been widely promoted and applied. Compared with the traditional information transmission technology, the bus has the characteristics of information digitization and interface standardization. Using the bus technology can greatly simplify the system design, so it has developed rapidly in recent years. Since the signal types and parameter types contained in the avionics bus simulator system are very complex, and in order to collect data of various bus types and non-bus types conveniently, the bus simulator system contains most of the existing signals Types, such as 1553B signal, 422 signal, 429 signal, AFDX signal, CAN signal, network signal, analog signal and discrete signal; and the parameter types contained in the bus simulato...
