Study on Improving Fault Tolerance Performance of Guided Weapon Fire Control Unit Through Decentralization of Fire Sequence Control and Message Transmission Restoration During Downtime Periods
Year: 2025
Type: article
Abstract: This study focuses on improving fault tolerance performance of Guided Weapon Fire Control Unit(FCU) based on decentralizing fire control and improved redundancy. The hot standby redundant FCU converts the spare module into a service module when a service module malfunctions. In the improved system, uninterrupted launch is possible even when above transition occurs because fire sequence control was transferred from FCU to separate Missile Control Unit(MCU), and an additional message recovery process was designed to compensate for the loss of message transmission during the transition time. Through experiments, the fault tolerance performance of the FCU was verified by measuring the role switching performance and message recovery performance.
