摘　　要：针对爆炸场中弹药爆炸零时难以获取以及多个测试设备难以同步触发、时间同步性差等问题,文中设计了一种基于ZYNQ+GPS的爆炸零时获取系统。该系统使用ZYNQ芯片作为控制核心,采用GPS同步技术对系统进行同步授时,为系统提供了高精度时钟。此外,针对恶劣的爆炸环境,系统采用了DDR+EMMC存储结构和磁耦隔离技术,有效地提高了系统的存储效率与可靠性。理论分析并验证了在GPS正常工作条件下,系统之间的最大时间误差为2μs。实验结果表明,该系统具有良好的时间同步性,能获取到精确的爆炸零时,为构建弹药爆炸威力场提供了有效的时间数据。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 2µs 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.
