Embodiment Construction
[0019] The model-based avionics simulation configuration control system architecture design method proposed by the present invention will be described in detail below in conjunction with the accompanying drawings.
[0020] The functional framework of the avionics simulation configuration control system involved in the present invention is as follows: figure 1 shown. When the avionics simulation configuration is changed, in order to avoid the very complicated process of reconnecting the electrical circuit, the avionics simulation configuration control system proposed by the present invention adopts the simulation data network based on the ARINC664 standard, wherein the ARINC664 standard is for An electronic special protocol (IEEE 802.3 and ARINC664 Part7) standard defined for data exchange between subsystems is a bus communication protocol specification based on ARINC429 and 1553B. The function of the system is divided into three parts: configuration management function, confi...

The invention discloses an architecture design method of avionics simulation configuration control system based on model. The design method includes system function division, system layer architecture design, function layer architecture design and executive layer architecture design. The system function division divides the system into configuration management function, configuration control execution function and simulation execution function; the system layer architecture design is abstracted with AADL components. The design method is a model based development method, which is easy to edit and modify, and convenient to sue. The design method can greatly reduce the cost of development and shorten the development time. The architecture of avionics simulation configuration control system is analytical model, which can validate functional properties and non-functional attributes through multi model analysis methods and can provide a convenient and effective way of verification before the system implementing.
Description
technical field [0001] The invention relates to the field of aircraft avionics system simulation and design, in particular to a model-based avionics simulation configuration control system architecture design method. Background technique [0002] Hardware-in-the-loop simulation technology is an effective method widely used in the design and modification of avionics systems to solve the problem of integration verification. The avionics semi-physical simulation connects physical avionics components and computer simulation models to the simulation system at the same time. There are a large number of interfaces and cables between each component and the simulation system, which need to be connected according to the aircraft avionics configuration design scheme to be simulated. When the configuration design scheme of the avionics system changes, the reconnection of interfaces and cables will be a very complicated and cumbersome task. [0003] At present, the research on avionics ...
