The fault-tolerant software design in warship control system

Firstly one distributed warship control system has been introduced. Based the analysis with the frame and network of this control system, this paper designs the redundant hardware and software architecture, the work mode and the work process of the two core - Tkernel and System in central console based on QNX. This paper designs reply-driven message passing software architecture, the method of fault diagnosis and recovery with hardware and software techniques. It´s an important reference in software design of warship control system.
