基于ZYNQ+GPS的抗干扰爆炸零时获取技术研究
Research on anti-interference explosion zero-time acquisition technology based on ZYNQ+GPS
摘要
Abstract
In view of the difficulty in obtaining the zero time of the ammunition explosion,and the difficulty in synchronous triggering and poor time synchronization of multiple test equipment in the explosion field,an explosion zero-time acquisition system based on ZYNQ+GPS is designed.In the system,the chip ZYNQ is used as the control core,and the GPS synchronization technology is used to synchronize the timing of the system,so as to provide the high-precision clock for the system.In addition,in view of the harsh explosive environments,the storage structure DDR+EMMC and magnetic coupling isolation technology are adopted for the system,so as to effectively improve the storage efficiency and reliability of the system.Theoretical analysis and verification have shown that the maximum time error between the system is 2 µs under normal GPS working conditions.Finally,the test results show that the system has good time synchronization and can obtain accurate zero time of explosion,providing reliable time parameters for reconstructing the ammunition explosion space-time field.关键词
