摘要
针对北斗短报文单次通信数据量限制自动气象站数据传输的问题,设计了基于北斗卫星的自动气象站数据传输管理系统。系统由FPGA处理器模块、北斗模块和外部检测控制模块组成。系统通过LZW编码和Huffman编码实现气象数据的高效无损压缩传输;系统基于北斗短报文实现对自动气象站的远程管理;系统具有自动检测和管理功能。目前,该系统已通过验证,气象数据传输效率提高了3倍,解决了北斗短报文单次通信数据量限制气象数据传输的难题,提高了对自动气象站的远程管理能力。
An data transmission and management system of automatic meteorological station based on Beidou satellite is de signed due to the meteorological data transmission is limited by single communication data quantity of Beidou short message. The system consists of FPGA module, Beidou module and external measure control module. According to LZW coding and Huffman cod ing, the system realizes efficient lossless compression transmission of data. The system implemented remote management of automatic meteorological station based on Beidou short message. The system has intelligent detection and management function. At present, the system has already passed the authentication and the data transmission efficiency has been improved 3 times. The problem that me teorological data transmission is limited by single communication data quantity of Beidou short message has been solved. Moreover, the system improveds the ability of managing automatic meteorological station.
