Abstract

Abstract: With the application of the integrated modular vetronics (IMV) system in ground vehicles, the system management and software reconfiguration should be researched to improve the fault handling capability and the level of system reliability. The avionics system management standardized in the ASAAC specification is studied, and a system management and software reconfiguration scheme based on asynchronous communication is proposed for the characteristics of IMV system. In addition, the system management configurations, as well as the detail design of system management software and module management software are presented. The scheme is applied and tested in the desktop and embedded systems. The analyzed and experimental results show that the proposed method can reduce the communication load in a multi-module IMV system and effectively cope with common faults of IMV system， such as abnormal exit of application software, network disconnection, module power-off, as well as redundant software running, which enables the IMV system to retain stable and self-contained under the occurrences of these faults and their combinations.
