Data Transmission System Design in Marine Seismic Data Acquisition System
摘要
Abstract
A long-distance redundant data transmission system is developed for time-lapse marine seismic data acquisition system. Serializer/deserializer (SerDes) technology is applied to archieve long-distance high-speed data transmission. A field programmable gate array (FPGA) is used as a control unit to ensure the synchronization and timeliness of the multi-node system. Two inter-backup data channels which transfer the same data frame at the same time are used between two adjacent nodes. The receiver verifies each data frame and chooses a correct one in hardware, thus effectively improving the stability and reliability of the data transmission system.关键词
