【摘要】 通过对态势标绘系统需求的分析,针对矢量符号在标绘系统容易出现延迟、闪烁和态势文件过大不易保存传输2个关键问题进行了深入研究分析,提出了多缓冲绘图机制和序列化存储方法,并设计实现了态势标绘系统。经过试验证明:多缓冲绘图机制能有效地避免海量矢量符号在显示过程中的闪烁和延迟;态势演播中的序列化存储方法,能有效压缩态势文件的大小,方便了态势文件的保存和传输。更多还原

【Abstract】 Based on requirements analysis of situation plotting system,this paper studies and analyzes in depth such key problems as vector symbol prone to delay or flicker in plotting system and posture file too large and not easy to be saved and transmitted.It puts forward such corresponding solutions as multi buffer mechanism and serialized storage method,and realizes the situation plotting system.The experiment results show that multi buffer mechanism can effectively avoid flicker and delay to display the massive vector symbol,and the serialized storage method can effectively compress the size of state file,convenient for posture file preservation and transmission.更多还原
