摘要
为了实现发射装置、接收装置及海洋可控源甲板监控系统的同步,需要利用高精度的GPS对钟系统实现在海洋环境中同步对钟。首先对海洋可控源甲板监控系统作简要介绍;分析在海洋环境中如何应用GPS对钟系统实现监控船与深海探测装置的时域和频域的同步;重点研究了在海底探测装置中设置的GPS对钟系统的单片机实时时钟(RTC)与GPS卫星的PPS秒脉冲的同步,从而达到了海洋可控源甲板监控系统与海底探测装置同步采集数据的目的。
To make use of GPS synchronization technology with high-precision to implement the synchronization technology in the marine environment is need in order to realize the synchronization of the transmitter, reeeiver and the deck monitored control system for marine controlled souree. First of all, a brief introduction of the deck moni-tored control system for marine controlled source is made. Secondly, how to apply GPS synehronization teehnology in making the time domain and frequency domain of a monitoring ship and the seabed detection device synchronized in the marine environment is analyzed. Finally, key research is made on the synchronization of Single Chip Micro-eomputer （SCM） ＇ s Real-Time Cloek（RTC） and the GPS satellite＇ s Pulses Per Seeond（PPS） set in the seabed detection device. Thereby, the aim, the synchronous data collection of the deck monitored eontrol system for ma-rine eontrolled source and the seabed detection device, is aehieved.
