摘要
地震勘探仪器是集当代先进技术(传感器技术、电子技术、计算机技术、数据传输技术、通讯技术等)为一体的综合系统.工程地震仪是一种解决工程实际问题的应用较为广泛的地震勘探仪器,一般用于小范围内矿产,水文地质,工程地质等领域.UDP是用户数据报协议简称,这种简化的UDP协议和服务在很多情况下是足够的.UDP协议不需要建立和维护连接,所以只需要极小的系统占用.由于这个特点,UDP可以对一些应用程序提供了一个非常有效的通信传输.DZG-1型数字地震仪是采用FPGA芯片作为采集模块控制器,工控机为主控单元的48道工程地震仪.在仪器的设计与使用过程中,发现数据传输速度是制约此类仪器发展的重要因素之一.本文以DZG-1型数字地震仪为例,讨论UDP协议在工程地震仪中的实现,数据传输速度达50Mbps以上,解决了数据传输问题.
Seismographs set of the most advanced technologies （such as sensor technology, electronics technology, computer technology, data transmission technology, communication technology, etc. ） for the integrated systero~ Engineering seismograph is a widely used seismic instrument, generally used for small scale mining, hydrogeology, engineering geology and other fields. UDP is short for User Datagram Protocol, The simplicity of UDP reduces the overhead from using the protocol and the services may be adequate in many cases. UDP communication consequently does not incur connection establishment and teardown overheads and there is minimal associated end system state. Because of these characteristics, UDP can offer a very efficient communication transport to some applications. DFG-1 digital seismograph uses FPGA chip as the acquisition module controller, IPC （ Industrial Personal Computer） as the main control unit, DFC--1 is a 48 channel engineering seismograph. In instrument design and instrument use, we found that the data transmission speed is an important factor restricting the development of such devices. In this paper, DFG-1 digital seismograph, for example, discuss the UDP protocol implementation in the engineering seismograph. Data transmission speed is greater than 50Mbps, To solve the problem of data transmission.
