A comprehensive modular avionics system service capability evaluation method

Abstract

The invention provides an integrated modular avionics system service capability assessment method which includes the steps of identifying and classifying resources provided by an IMA (Integrated Modular Avionics) platform, performing independence identification and quantification on resources of the IMA (Integrated Modular Avionics) platform, setting up an IMA (Integrated Modular Avionics) platform resource matrix, obtaining the maximum service capability of the IMA (Integrated Modular Avionics) platform from the IMA (Integrated Modular Avionics) platform matrix, determining whether an IMA (Integrated Modular Avionics) system satisfies the service capability demands of avionics system functions, resetting elements in a corresponding resource matrix to zero when resource failure occurs or reducing values according to the degradation of resources, repeating the determination process, and assessing the service capabilities of the IMA (Integrated Modular Avionics) platform after resource failure. The integrated modular avionic system service capability assessment method is capable of assessing the service capabilities of the IMA (Integrated Modular Avionics) platform with resource sharing characteristics by quantifying the service capabilities of the system, thereby helping to maximize the resource utilization of the system. Furthermore, the integrated modular avionic system service capability assessment method helps system integrators reasonably plan the variety and quantity of residence functions of the IMA (Integrated Modular Avionics) platform, thereby enhancing the 'failure-safety' capability of the avionics system.

Description

technical field [0001] The invention belongs to the technical field of comprehensive modular avionics, in particular to a method for evaluating the service capability of a comprehensive modular avionics system. Background technique [0002] The Integrated Modular Avionics (IMA, Integrated Modular Avionics) system implements the corresponding avionics system functions by residing in different partitioned applications on the hardware resource platform, which reduces the cost of manufacturing and maintenance, and gradually replaces the IMA system. The traditional combined avionics system has become the preferred avionics architecture for the new generation of passenger aircraft, and has been applied to Boeing 787, Airbus A380 and COMAC C919 aircraft. [0003] With the development of technology and the continuous improvement of avionics system requirements, more and more avionics system functions are integrated into the IMA platform. Therefore, the number and types of partition ...

Problems solved by technology

Under the IMA system architecture, the realization of each specific system function depends on the service capability of the IMA platform itself, and the existing service capability evaluation method is only for specific avionics functions, such as the performance of navigation, communication, collision avoidance and other systems evaluation, the service capability evaluation of the IMA system cannot be completed, which brings difficulties to the integration of avionics systems, and makes it impossible for system integration manufacturers to accurately estimate the service capabilities of the IMA platform, so they can only adopt conservative strategies, resulting in a waste of system resources. Increased design, manufacturing and system integration costs
