摘要: 为减少海洋资料浮标通信系统数据传输的时间和费用,本文针对传输数据类型,采用位拼接、LZW和改进的LZW算法结合的方法对数据进行实时无损压缩。该压缩技术平均压缩率在40%以下,降低了浮标通信所需时间。实际应用证明,该技术提高了数据压缩效率,缩减了通信成本,保证了系统的可靠性。

关键词: 数据压缩技术, 位拼接, 海洋资料浮标, LZW算法, 改进的LZW算法

Abstract: We propose a realtime lossless data compression technology forbit splicing, LZW and improved LZW combined approach to reduce transmission time and cost of the communications system of an ocean data buoy. Its average compression ratio is less than 40%, which can reduce communication time.Practical application shows that this technology improves data compression ratio,reduces communication cost and guarantees system reliability.

Key words: ocean data buoy, LZW, data compression, bit splicing, improved LZW
