空中交通监视电子地图平台设计

Design of Application of Electronic Map Platform in Air Traffic Surveillance

采用Java技术,从底层设计并实现了一个航空矢量电子地图平台,介绍了平台结构和设计要点。针对矢量电子地图中普遍存在的响应迟滞问题,提出了基于图层自检的多级过滤绘制方法,显著提高了地图响应速度。在处理监视数据时,采用基于混合门限的自适应刷新策略,有效地控制了平台资源负载情况,平台稳定性得以提高。

Designed an aviation electronic vector-map from the bottom level and implemented it with Java. Introduced the main architecture and key modules. In order to reduce the response time ,painting process is optimized by multi-filtration based on the concept of layer-self-determination. Analyzed the relationship among map scale,refresh rate and resource cost. The efficiency is enhanced by adopting an adaptive refresh strategy utilizing a hybrid threshold.
