摘要
针对目前气象控制及管理平台的特点,设计基于嵌入式Linux平台的气象控制与管理系统。该系统依托北斗卫星通信实现了对各区域中各功能模块的控制操作,并采用基于Linux平台下的Qt图形用户界面开发工具设计一套操作界面,实现了对多个区域气象数据的实时采集、显示、存储等处理。通过LZW算法和固定位长算法混合编码实现自动气象站数据的无损压缩,进一步提高了对自动气象站远程管理能力和气象中心的便携性、灵活性,为建立移动气象中心提供一种思路。
Aiming at the characteristics of current meteorological control and management platform,we designed an embedded Linux platform-based meteorological control and management system. Relying on the Plough satellite communication,the system realises the control and operation on each functional module in every area,we also used the Linux platform-based Qt graphical user interface development tools to design a set of operation interfaces which implemented the processing of real-time collection,display and storage on meteorological data in multiple areas. In it,the system efficiently realises the lossless compression of automatic meteorological station data through the mixed code using LZW coding algorithm and fixed bit length packing coding algorithm. In this way we further improved the portability and flexibility of the remote management capability on automatic meteorological stations, and this provided a new thought for the construction of mobile meteorological centres.
