利用无线网卡实现气象报文的备份传输

Backup transmission for meteorological messages based on wireless network card

随着气象现代化建设的推进，气象报文早已不再通过邮局报房或人工电话口传，而是在Internet基础上建立行业局域网，在此局域网内部通过FTP程序自动传输。据中国气象局ASOM系统统计，各省气象报文传输的及时率平均已达98％以上，一年中，任何一个站如有3～4d网络中断，其全省全年的报文传输率就会低于全国平均水平，影响全省业务质量。而各种原因造成的市县局网络中断是造成报文无法自动传输的最主要因素，利用无线网卡实现气象报文的备份传输，可解决这一问题。

With the advancement of meteorological modernization construction, meteorological messages are not transferred through the radio room of the post office or artificial telephone transmission,but it is automatic transferred by use of FTP program within the LAN created based on the Internet. According to statistic system A$OM in China Meteorological Administration, timeliness of meteorological messages transmission in each province has reached an average of more than 98~, which means in a year any station that has 3-4 days＂ network interruption will cause messages transmission rate in every province during the whole year lowering than the national average and affect service quality. The network interruption in the bureau of the city and county is the chief reason that causes the message cannot be automatically transferred. The problems mentioned above can be solved by using backup transmission for meteorological messages based on wireless network card.
