空军机场修正海压数据共享系统的设计与实现

Design and implementation of QNH data sharing system for air force airport

根据从咸阳机场向四个空军导航台引接修正海压数据的需求,开发了空军机场修正海压数据共享系统。该系统在民航气象数据库业务系统的基础上,开发数据采集及处理程序和前端显示软件,采集咸阳国际机场自动观测系统修正海压数据进行解析,再通过前端显示软件向四个空军机场用户展示。前端显示软件基于B/S架构,运用ASP.NET平台搭建网页,提供了hPa(百帕)和mmHg(毫米汞柱)两种单位的修正海压数据,该软件运行于Windows平台,用户通过IE浏览器即可获取实时修正海压数据。

According to the requirements of transmitting QNH data from XianYang International Airport to four air force navigation stations,the QNH data sharing system is developed.Based on the NWMC database system,the software for data acquisition and processing and the Display Terminal software are developed to collect and parse QNH data from the Automatic Observation System of XianYang International Airport,and then display it to the users of four air force airports through the display terminal software.The display terminal software adopts B/S architecture,and uses ASP.NET framework to build web pages which provide QNH data in hPa and mmHg units.The software runs on Windows platform,and users can obtain real-time QNH data through IE browser.
