408UL地震数据采集系统的地震区域网络

Seismic LAN for 408UL seismic data acquisition system

408UL地震数据采集系统的地震区域网络采用标准的TCP/IP协议,有异步通信、同步通信两种传输方式,用网关连接各节点,路由表自动建立、自动更新,提高了系统的灵活性、适应性。本文介绍了有关的网络技术的概念和408UL仪器地震区域网络的结构特点,以及排列跨越障碍的方法。

The standard TCP/IP protocol has been used in seismic LAN of 408UL seismic data acquisition system. There are two transmission types： synchronous transmission and asynchronous transmission. The netnodes are connected by gateway and the routing tables are constructed and displaced automatically, which improved the flexibility and adaptability of system. The paper introduced the technical conception of network, structure feature of 408UL Seismic LAN and methods for spread going across an obstacle.
