【摘要】 40 8UL数据采集系统应用了地震区域网络、链路和网络节点的概念 ,把整个网络分成控制节点、记录节点、数据缓冲节点和采集节点四类。将数据通讯分成同步通讯和异步通讯两种。每两类节点之间可以进行一种或两种形式的通讯。同步通讯采用与以往遥测地震仪相同的数据传输方式 ,异步通讯采用OSI/RM协议模型 ,运用局域网的通讯协议 ,进行数据交换 ,实现了计算机局域网通讯技术在大型遥测地震仪中的应用 ,同时也降低了遥测地震仪的制造成本。更多还原

【Abstract】 The paper puts forward concepts of seismic areal network,link and network nodes that divide the whole of network into control nodes,recorder nodes,data buffer nodes and acquisition nodes. Data communication has two kinds of communication modes that are synchronous communication and asynchronous communication. Point to point communication between network nodes may adopt one communication level or two communication levels. Data transmission mode of synchronous communication is the same as that adopted in old remote seismic equipment. And asynchronous communication adopts OSI/RM protocol model. Communication protocol of local area network is used between asynchronous to transmit the data in the line. So it can reduce production cost by adopting computer local area network communication technology to large-scale remote seismic equipment.更多还原
