| 摘 要： | 为了解决大数据量快速传输的问题,当前的测井系统传输数据时一般采用高传输速率。文中介绍了高速测井系统中地面接口通信板的设计,其中包括使用均衡技术来减小电缆上传输信号的失真,以及利用FPGA从接收数据中提取位同步和帧同步。实践证明,地面接口通信板可以使整个测井系统的传输速率达到100kbps,从而极大地提高测井效率。

| Abstract: | At present,logging apparatus adopt high-rate communication rate generally for fast transmission of great data quantity.In this paper,the design of ground interface board for high-rate logging communication system is introduced,which consists of the reduction of the signal distortion on logging cable via using equalizer technology.Also,the extractions of bit synchronization and frame pulse synchronization from received data by FPGA are introduced in this design.In practice,the communication rate can reach 100kbps,and ground interface board can improve logging efficiency. |
