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 method to solve the problem of high speed data transmission of logging cable, OFDM technology has been used in logging high speed data transmission system. The physical layer of the existing OFDM logistic transmission system only provides a single high-speed data transmission channel, and all the logging service data is loaded onto this channel for transmission. However, logging business data is diversified, and different business data have different requirements on transmission performance. In this paper, a multi-service OFDM logging transmission system is designed according to the characteristics of logging service data to meet different types of well logging data The need for transmission.
