Problems solved by technology

[0006] 3) There are a variety of message formats between different devices. Every time a message format is added, the previous program needs to be re-extended, and the corresponding message packaging and unpacking functions can be added, and the attention cannot be focused on the problems that need to be solved. business issues;
[0007] 4) With the continuous increase of participating resources in the system and the increasingly complex relationship between them, there is a lack of a flexible management mechanism to use various resources more effectively

Embodiment Construction

[0034] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0035] The basic thinking of the present invention is as follows: how to integrate large-scale systems and develop new applications on them is a problem often faced by developers. Before the advent of middleware, developers had to solve these difficult problems directly. In the actual software development process, more than half of the time and experience of developers are spent on issues that are not directly related to the business. Middleware is currently a key technology to realize transparent access between heterogeneous systems. It shields the differences in hardware environment, operating system and programming language among the various components in the distributed system. Plug and play in the system has laid a solid technical foundation.

[0036] But in avionics systems, a large number of real-time applications need to model thei...

Abstract

The invention belongs to an avionics system task processing platform design and development technology, and relates to an embedded software operating platform design method based on a DDS, and a simulation platform. The embedded software operating platform design method comprises the following steps: 1, DDS middleware is deployed in a kernel of a VxWorks6.6 operating system; 2, the DDS is configured under the VxWorks6.6 system, and data reception and transmission are achieved through design; 3, a CPCI drive program is achieved under the VxWorks6.6 system, and thus the system can complete boardcard calling and data reading through a drive; 4, a CPCI bus drive program is designed under an AcoreOS653 operating system, and board card calling and data transmission are completed; and 5, a VxWorks6.6 board card and an AcoreOS653 system board card achieve two-way data transmission through a CPCI board card. A flexible data distribution scheme is provided for an airborne embedded platform, andthe embedded software operating platform design method can be suitable for design and development of an avionics task system.

Description

technical field [0001] The invention belongs to the design and development technology of an avionics system task processing platform, and relates to a design method of a DDS-based embedded software operation platform and a simulation platform thereof. Background technique [0002] With the growth of aircraft mission capabilities, the multi-electricity of aircraft systems, and the development of avionics software and hardware technologies, new functions of aircraft avionics systems have been continuously developed. These functions increase the complexity of the system while adding new capabilities. In order to meet the ever-increasing demands and at the same time solve the problems of system scalability, reliability and complexity, the avionics industry has developed the Integrated Modular Avionics System (IMA) and Distributed Integrated Modular Avionics System (DIMA). IMA refers to a set of system structures composed of standard format processing modules and standard forma...
