大型测试网络在工程技术与科学研究的各个领域得到越来越多的应用,这种测试网络的特点之一是空间分布可以大到几十km,其二是测量点数可以多达上千个。这种测试网络中有很多情况下要求对各测试点同步采样,例如管道泄漏的监测、电网浪涌的测试、地震波,风速的测量 Large-scale test networks are gaining more and more applications in various fields of engineering technology and scientific research. One of the characteristics of this test network is that the spatial distribution can be as large as several tens of km, and the second is that the number of measurement points can be up to a thousand. There are many situations in this test network that require simultaneous sampling of test points such as monitoring of pipeline leaks, tests of grid surge, seismic waves, wind speed measurements
