| 摘要: |
| 为实现对二次雷达航迹数据的实时记录以及事后的回放分析，设计并研制了基于VxWor
ks实时系统的嵌入式记录仪，采用自定义缓冲队列的数据传输机制，充分考虑了任务之间
的同步及互斥，并利用PC104板卡的硬件辅助时钟进行系统设计。实践证明，在航迹数据均
值速率3.84 kbyte/s（96批/秒）（峰值速率为20.48 kbyte/s即512批/秒）的情况
下，能达到正常实况回放的效果。 |

| Abstract: |
| The module based on Vxworks is designed and developed to record and replay the t
racks
in the Secondary Surveillance Radar(SSR). The mechanism of buffer queue custome
d is
used in software design, in which the synchronization and mutex between tasks
is considered, and the auxiliary clock of PC104 is adopted. The practice shows t
hat
the tracks relayed in the monitor can achieve the effect like live Telecast vid
eo after the data in the average 3.84 kbyte/s rate (96 packet/s) (the peak
20.48 kbit/s rate or 512 packet/s）) is recorded. |
