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.
Seismic exploration instrument is an integrated system integrating advanced technology (sensor technology, electronic technology, computer technology, data transmission technology, communication technology, etc.). Seismograph is a widely used seismic exploration instrument to solve practical engineering problems , Generally used in a small area of mineral, hydrogeology, engineering geology, etc. UDP is short for user datagram protocol, which is sufficient in many cases.UDP protocol does not need to establish and maintain the connection, So only a very small system footprint is required.Because of this feature, UDP can provide a very effective communication transmission for some applications.DZG-1 digital seismograph uses FPGA chip as the acquisition module controller and IPC Unit of 48 engineering seismograph in the design and use of the instrument and found that the data transmission speed is one of the important factors restricting the development of such instruments.This paper DZG-1 digital seismograph, for example, to discuss the UDP protocol in engineering Seismograph in the realization of data transmission speed of 50Mbps or more, to solve the problem of data transmission.
