Problems solved by technology

Therefore, the current IMA system is considered to be only at the level of the first generation. Although the avionics application software has realized the sharing of underlying resources, it has not achieved the flexibility of resource sharing and the efficiency of resource utilization. risk of compromising system security
The root of all this is that the existing IMA system does not support dynamic reconfiguration of the system, that is, the dynamic configuration of software on hardware resources cannot be realized

Embodiment Construction

[0020] The specific embodiment of the present invention is described in detail below in conjunction with accompanying drawing:

[0021] refer to figure 1 As shown, the development platform of the example of the present invention, the hardware mainly includes 3 basic general processing modules (M1, M2, M3), 1 backup general processing module (M4) and 1 massive memory module (MMM), and a support Dynamically reconfigured switch (TTFC), the software includes four application programs A, B, C, and D, and the four applications are deployed in three general processing modules according to certain rules, namely: application software A and B are loaded in the general processing module M1 and C are loaded in the general processing module M2, and D is loaded in the general processing module M3. In addition, each general processing module is deployed with the module reconfiguration management application software (CPURC), and the system level reconfiguration management main application so...

Abstract

The invention discloses a system-level reconstruction management application software master-slave switching method, which is applied to a secondary management and control based IMA (integrated modular avionics) system. The method comprises the steps that 1) two pieces of system-level reconstruction management application software are deployed on two different general processing modules respectively according to pre-settings after the IMA system is powered on, and a master-slave relation is set according to ID numbers; 2) system reconstruction is carried out after the system-level reconstruction management master application software SYSRC_M breaks down, the ID number of the reconstructed system-level reconstruction management master application software SYSRC_M is the sum of an original ID number of the original system-level reconstruction management slave application software SYSRC_S and an original ID number of the original system-level reconstruction management master application software SYSRC_M, and the ID number of the reconstructed system-level reconstruction management slave application software SYSRC_S is the ID number of the original system-level reconstruction management master application software SYSRC_M. The master-slave relation of the system-level reconstruction management application software is determined according to the ID numbers, when the system-level reconstruction management master application software SYSRC_M breaks down, the system-level reconstruction management slave application software SYSRC_S switches into a master control mode automatically, and a normal management mode of the system is recovered, thereby ensuring normal operations of the system, and improving the overall security of the system.

Description

technical field [0001] The present invention relates to a dual-redundancy control mechanism for system-level reconfiguration management application software on an IMA system for secondary control, and in particular to a dual-redundancy control mechanism for system-level reconfiguration management application software by setting priorities mechanism. technical background [0002] Integrated Modular Avionics (IMA) is replacing the traditional combined avionics, applied in more and more new military and civilian aircraft projects, and becomes an important direction of future avionics development. These IMA avionics systems generally adopt the space partition, time partition and scheduling technology defined by the ARINC653 standard to support avionics application software of different key levels to share the underlying resources, and avoid mutual influence or even malicious damage of avionics applications in space and time. It provides technical support for the safety and reli...
