This text has explained the basic method of the transformation for three-dimensional seismic visual data form, the access scheme of the magnanimity data, and raising conversion speed of the data through line interlacing scanning. 阐述了三维地震资料可视化系统数据格式转换的基本方法,以及海量数据的存取方案,通过隔行扫描的办法,提高了数据体转换速度。
The transmission of E1 data packet to EPON bus was realized by conversion of HDB3 line encoding to NRZ digital signals, setting up clock of system and network, organizing EPON data frame, and generating synchronization clock of E1 circuit simulation etc. 其E1数据包到EPON总线的传输,通过HDB3线路编码到NRZ数字信号的转换,系统及网络时钟设定,EPON数据帧的组织,E1仿真电路同步时钟的产生等步骤实现。
Vectorized data conversion of raster data for line feature 线状要素的栅格数据矢量化
Management of communication collects the data into a unified TCP/ IP protocol packet and sends to the PC, will also be issued to the top of the TCP/ IP packet of conversion kits in line with the agreement of the field data. 通讯管理机将现场采集来的数据转化为统一的TCP/IP协议数据包发送到上位机,同时也将上位机发来的TCP/IP数据包解包转换为符合现场设备协议的数据。
