Abstract

The invention provides a fault detection and health management method for a core computing platform for a missile-borne inertial navigation system and based on a multi-core DSP. Fault detection and health management of the core computing platform for the missile-borne navigation system are realized through processes of data acquisition and transmission, data preprocessing, feature extraction, state monitoring, health management and the like by adopting methods of multi-core processor heartbeat monitoring multi-core jump monitoring, multi-power supply monitoring, atmospheric pressure and ambient temperature monitoring, high-speed 1553B bus monitoring and the like.

Description

technical field [0001] The invention belongs to the technical field of embedded systems, and in particular relates to a method for fault detection and health management of a multiprocessor computer. Background technique [0002] The missile-borne inertial navigation system has the characteristics of poor detachability in the installation method, the use environment is periodically exposed to extreme temperature and humidity conditions, the number of tasks in the life cycle is small, and the storage period is long. Therefore, the core of the missile-borne inertial navigation system The computing platform is limited by the above usage conditions, and needs to have strong fault detection and health management capabilities. At the same time, the fault detection mechanism needs to have a low false positive rate, a high fault detection rate, and the ability to isolate faults. [0003] The application range of fault detection and health management technologies in European and Ameri...
