Abstract
Addressing the urgent need for fuse safety and reliability of long-range rocket projectiles in highly dynamic and strongly interfering battlefield environments,this paper proposes a safety control logic for a heterogeneous dual-core(MCU+FPGA)electronic safety system(ESAD)based on a"threshold+time window+sequence"mode.Firstly,guided by the GJB 373 B—2019 standard,three types of informa-tion-acceleration during the boost phase,apogee,and target acquisition-are selected as three-stage ar-ming incentives.Secondly,a Markov theoretical model is employed to calculate the system's failure rate,yielding an unintended arming probability of 1.081 6×10-9,which meets the specified requirements.To further enhance radiation tolerance and fault tolerance,a built-in voting triple modular redundancy(TMR)architecture is introduced into the acceleration channel.Furthermore,detailed design and simula-tion are conducted for functional modules within the FPGA,including acceleration environment recognition and apogee environment identification.Simulation results demonstrate that the designed FPGA modules of electronic safety system can accurately identify environmental information and control switches according to the predefined safety control logic,thereby realizing the safe control of electronic safety system.The de-sign complied with the safety design requirements of GJB 373 B—2019.关键词
