ns级时序控制同步机主要用于多套高速数据采集系统、多套高速摄影测试系统的精确同步触发、精确延时触发控制等方面,对军工靶场试验测试具有重要意义;详细介绍利用NIOS Ⅱ软核处理器设计嵌入式五通道ns级时序同步机的软硬件实现技术,实现了五通道ns时序参数的输入、存储、整定以及时序输出控制等;时序在线跟踪测试表明,该同步机完全满足设计要求,其各通道时序控制精度为20ns,单通道时间设置范围为20ns至100s,可应用于工程实际测试;本同步机的设计技术对相关开发人员具有一定的参考意义。
ns timing control synchronous machine is mainly used for multiple sets of high-speed data acquisition system, multiple sets of high-speed photogrammetric test system, precise synchronization trigger, precise delay trigger control and other aspects of the military range test is of great significance; detailed introduction of NIOS Ⅱ soft The hardware and software technology of embedded five-channel ns-level timing synchronous machine is designed by the nuclear processor to realize the input, storage, tuning and timing output control of the five-channel ns timing parameters. The sequential on-line tracking test shows that the synchronous machine fully satisfies the design Requirements, the channel timing control accuracy of 20ns, single-channel time setting range of 20ns to 100s, can be applied to the actual engineering test; The design of the synchronous machine technology for developers have some reference value.
