A cross interconnected ima core computing/processing platform

Abstract

The invention provides a cross-connect IMA core computing / processing platform. The cross-connect IMA core computing / processing platform comprises two integrated core processors (ICP), a communication network system and two remote data concentrators, and the communication network system and the two remote data concentrators are connected with the comprehensive core processors. The two remote data concentrators (RDC) are correspondingly connected with the ICPs respectively. Control and management of a whole avionics system, data computing, information processing, data storage, data communication and data loading and unloading services are achieved through the ICPs. According to the cross-connect IMA core computing / processing platform, on the basis of an open type system structure and software / hardware interface standard design of a unified high-speed network, the universality of an LRM module can be enhanced, mix and match using of products of different suppliers is supported, and safety is improved.

Description

technical field [0001] The invention relates to the field of airborne computer systems, in particular to an AFDX network-based, open cross-connected IMA platform architecture of a comprehensive modular avionics system. Background technique [0002] With the continuous development of airborne computer, communication network and packaging structure technology, the avionics and mission systems of large aircraft (transport aircraft, passenger aircraft, etc.) lower than class B (i.e. failure rate less than 10 -7 ), the security level of the airborne communication network is not lower than A level (the failure rate is less than 10 -9 ). Driven by this demand, a highly secure high-speed IMA core computing / processing, communication network, system packaging and interface technology has been rapidly developed and applied. The system architecture, important components (equipment / modules) and their interconnection methods of the IMA platform will have a major impact on the overall s...

Problems solved by technology

At present, the IMA platform mostly adopts a non-cross-connected architecture or a non-open architecture. This system architecture design has potential safety hazards such as single point failures, common mode failures, and common cause failures (such as when a group of resources failure, when a design flaw or a common mode failure occurs, it will lead to the loss of the entire avionics system function), so a new generation of aircraft design urgently needs a cross-connected, open IMA platform architecture to enhance system robustness Reliability, while improving system fault tolerance, reliability and availability
