海底观测站可以提供长期、实时的海底监测数据，对于海洋科学特别是海底地震观测重大科学技术的研究具有重要意义。链式海底数据采集与传输系统是有线海底地震观测站的雏形和基础。本文设计并构建了一个基于Zynq-7000 Soc（片上系统）和时钟同步的链式数据采样和传输系统（SQSTS）。首先，我们基于Zynq-7000 Soc和ADS 1256实现了高精度海底数据（24位）采样。利用P88 1588 PTP（精确时间协议）时钟同步板和Zynq-7000 Soc内部晶体振荡器提供的PPS（每秒脉冲）信号，时间戳高达微秒级，对于每个地震仪节点采样的地震数据可以支持后续反演地震数据。此外，还研究了基于千兆位收发器和光缆的SQSTS中连接节点的高速数据传输链路。使用Aurora IP核实现了传输链路。理论计算表明数据传输总线带宽可达4 Gbps，同时其可靠性也得到了实验证明。实验结果表明，该系统具有数据采样精度高、高速传输稳定可靠的特点，具有良好的应用前景。
Seafloor observatories can provide long-term, real-time submarine monitoring data, which has great significance for the study of major scientific technology in marine science, especially in the seafloor earthquake observation. The chained submarine data sampling and transmission system is the prototype and foundation of cabled seafloor earthquake observatories. This paper designs and builds a chained data sampling and transmission system (SQSTS) based on Zynq-7000 Soc (System on chip) and clock synchronization. At the beginning, we realized high-precision submarine data (24 bit) sampling based on Zynq-7000 Soc and ADS 1256. Using the PPS (Pulse per second) signal provided by the P88 1588 PTP (Precise time protocol) clock synchronization board and the inner crystal oscillator of the Zynq-7000 Soc, the time stamp up to the microsecond level, for the seismic data sampled in each seismometer node can support subsequent inversion of seismic data. In addition, a high-speed data transmission link connecting nodes in SQSTS, which is based on the Gigabit transceiver and optical cable, has been investigated. The transmission link has been realized by using the Aurora IP core. The theoretical calculations indicate that the data transmission bus bandwidth can reach 4 Gbps, while in the meantime its reliability has been proved by experiments. The experimental results show that the system owns the characteristics of high data sampling accuracy, stable and reliable high-speed transmission, and has promising application prospects.
