【摘要】 当前,地震仪器网络主要是采用OSI/RM标准,以传统的数据链传输为基础形成的专用协议来协调进程间通讯,从而完成地震数据的传输。因此,当前网络地震仪器不仅没有采用统一的网络标准,而且更重要的是由于OSI/RM模型过于庞大和复杂,导致其网络性能不高,主要表现在数据传输率低和对数传电缆的性能要求较高等方面。本文指出地震仪器使用技术成熟的以太网进行数据传输将显著提高传输性能。文章针对地震仪器数据传输的特点和要求,对地震仪器使用以太网传输地震数据时需要重点解决的供电方式、时间同步和传输错误处理等问题进行了探讨,对下一步地震仪器的发展和网络数据传输的主要技术手段提出了创新性的见解。更多还原

【Abstract】 At present,seismic instruments mainly adopt OSI/RM standard network.By adopting the special agreement based on traditional data transmission chain to coordinate communication between different processes,thus the transmission of seismic data can be completed.But this OSI/RM model is too large and complex,resulting in lower network performance,lower data transmission rate and even higher performance requirements for cable and so on.Ethernet will significantly improve data transmission performance.Aiming at characteristics and requirements of seismic data transmission,this paper discuss some important problems such as power supply,time synchronization and transmission error recovery when seismic instrument with Ethernet,then the author put forward his innovative ideas about the future development of seismic instruments and data transmission network.更多还原
