Embodiment Construction

[0030] The present invention is described in detail below in conjunction with accompanying drawing to specific embodiment of the present invention:

[0031] refer to figure 1 As shown, it is a schematic diagram of the composition framework of the hybrid dynamic reconfiguration system of the distributed integrated modular avionics system of the present invention, including the first to fifth computing modules, the first and second TTE switches, and the first and second Ethernet switch.

[0032] The first to fifth computing modules (numbered M1 to M5) are connected by the first and second TTE switches, and the first and second TTE switches execute the TTE protocol. The protocol uses the global clock to start data transmission and reception during the communication process, and the operation of each network component (switch and independent computing module) is only related to the global clock, and has nothing to do with the working status of other components. This feature ensu...

Abstract

The invention discloses a distributed integrated modular avionic system hybrid dynamic reconfiguration system and method. The distributed integrated modular avionic system hybrid dynamic reconfiguration system at least comprises a first operation module, a second operation module, a third operation module, a fourth operation module, a fifth operation module, a first TTE exchanger and a second TTE exchanger, wherein the first operation module, the second operation module, the third operation module, the fourth operation module and the fifth operation module are connected through the first TTE exchanger and the second TTE exchanger, and the first TTE exchanger and the second TTE exchanger execute the TTE protocol. According to the protocol, in the communication process, a global clock is adopted for starting data receiving and transmitting, and the operation of each TTE exchanger and each operation module is only related with the global time. One operation module is set as the main reconfiguration management module to manage the remote reconfiguration work of the whole system in a uniform mode, and another operation module is set as the backup module.

Description

[0001] 【Technical field】 [0002] The invention relates to the field of avionics, in particular to a system and method for real-time dynamic reconfiguration of a distributed integrated modularized avionics system. [0003] 【Background technique】 [0004] The proportion of avionics system in the cost of the whole aircraft is increasing, 35%-40% for civil aircraft, and 50% for military aircraft. As the system structure becomes more and more complex, more and more functions need to be integrated, so that the aircraft has become a real information system. The continuous progress of communication and information management technology has promoted the research and development of new avionics equipment. The Distributed Integrated Modular Avionics System (DIMA) is an important improvement within the scope of the IMA (Integrated Modular Avionics System) system. It combines the joint and the advantages of the IMA concept, and put forward higher and higher requirements for system perform...
