摘　　要：经过“九五”数字化改造 ,地震前兆台站的数据通信基本上采用有线信道实现。随着网络通信技术的进步和发展 ,为地震台站的数据通信开辟了一条新的途径。通过对数据采集器进行改造 ,不仅精度有了提高 ,而且也支持网络通讯和一些常用的服务。通过网络 ,仪器作为一个服务器可以通过多种客户端软件进行访问。并对高精度数据采集器实现网络通讯进行了介绍 ,展示了通过多种客户端访问仪器、传输前兆数据、监控仪器状态和跟踪实时产出数据等等。Communicating method for Earthquake precursory instruments has been grealty changed since the implementation of digital reconstruction during the Ninth five-year Plan.But There are still some problems in the Communicating practice.Network-communication technology provides a new way for the solution of these problems.In the blue print of the Tenth Five-year Plan,the Implementation of network technology for earthquake precursory instrument is an important section.According to this plan,the precision of data logger will be enhanced and it can support network communication and some common network service.Through the network multi-client software,the precursory instruments as server can be accessed.In this paper,the network communication through high-precision data logger is introduced.And several client ways to access the instrument,to exchange precursory data,to monitor the instrument and tracing the real-time data are demonstrated.The experiments in this paper may provide some experience for the application of network technology to earthquake precursory instruments.
