摘要 OFDM技术作为解决测井电缆高速数据传输问题的有效方法,目前已经被用于测井高速数据传输系统。现有的OFDM测井传输系统的物理层只提供一个单一的高速数据传输通道,所有的测井业务数据均加载到这个通道上进行传输。然而测井业务数据具有多样性,不同的业务数据对传输性能的要求不一样,本文针对测井业务数据的这一特点设计了一种多业务OFDM测井传输系统,以满足不同类型测井数据对传输的需求。 As an effective solution to high speed data transmission for logging cable, OFDM technology has been adoped in the logging cable transmission system presented in this paper.In general, only one channel is provided for high speed data transmission in the physical layer of data transmission system, and all kinds of the logging business data are transmitted through this channel.However defferent business data need defferent data transmission performance. A multi-service OFDM transmission system is presented to meet the diverse speed requirements of different types of logging data.
