极端环境下自动气象站数据远程传输方案设计

Design of Long-Distance Transmission Solution for Automatic Meteorological Station in Extreme Circumstance

讨论在我国珠穆朗玛峰地区的极端环境下自动气象站数据传输系统的构建和可靠性设计;通过分析和比较目前国内常用的自动气象站数据通信方式的优缺点、适用范围及珠峰地区的极端自然条件,提出采用我国自主研发的"北斗"卫星导航定位系统来实现在珠峰大本营及周边地区建立自动气象站,设计了适应于"北斗"系统的通信控制系统及通信方案;分层思想提高了系统的扩展性和维护性;综合采用重连、回执、重发、校验等机制保障了系统的稳定、可靠运行。

The construction and the reliability of an automatic weather station in the extreme circumstance of the Everest region are discussed. The Compass Navigation Satellite System was adopted in establishing the automatic weather station in the Everest region. A brief analysis and comparison of the data transmission methods commonly used are conducted. The communication control system and communication solution are designed to fit in with the Compass Navigation Satellite System. The hierarchy idea is applied to improve the expansibility and maintainability, and the mechanisms such as re-connection, receipt, resending and verification are utilized to guarantee the stability and reliability of the system.
