一种基于北斗卫星通信的渔业信息编解码方法

A FISHERIES INFORMATION ENCODING AND DECODING METHOD BASED ON BEIDOU SATELLITE COMMUNICATION

在基于S3C2440的嵌入式渔业信息采集终端上应用一种GB2312的编码方法,把鱼总产量、各经济鱼类产量、捕获时间、工作时长、捕获地点等信息伪装为汉字。该采集终端跟渔船上已安装的北斗星通的北斗海洋渔业船载终端共享一个北斗通道,利用该通道把伪装为汉字的渔业信息以报文形式发送到陆地上的数据中心。数据中心对接收到的汉字进行解码为原渔业信息。实践表明,该方法适用于采用北斗报文进行渔业信息通信。

On S3C2440-based embedded fisheries information acquisition terminal a GB2312 encoding method is applied, it disguises thefisheries information as the Chinese characters, such as the total production of fishes, each precious fish production, the time of capture,working hours and the position of capture, etc. The acquisition terminal shares the same Beidou satellite channel with ship-borne terminaldesigned by BDStar Information Service Co. , Ltd, and uses this channel to send fisheries information disguised as Chinese characters to datacentre on land in the form of message. The data centre decodes the received Chinese characters to the original fisheries information. Practicesshow that this method is suitable for fisheries information communication using Beidou message.
