【Abstract】 In response to the requirements of modern weapons for ammunition damage probability and the tactical and technical requirements of miniaturization and intelligence of fuze, this article considers safety, stability, and miniaturization of fuze. A miniaturized fuze safety and initiation control circuit with error-proofing function was designed based on domestic FPGA chips. The circuit gives corresponding control signals according to setting methods of triggering, proximity and delay for fuze, utilizes digital signals for flexible control based on target area information and ballistic information, and uses the LVDS protocol for information exchange with the upper computer. Finally, the normal logic timing of the circuit is verified using Modelsim simulation software. The results of safety and arming function experiments and initiation function experiments show that the circuit can be armed safely and reliably and achieve multi-functional initiation.更多还原
