Abstract
After digital transformation, the regional seismic network of Jinchang city, Gansu Province, newly added four digital stations, expanded the scope of monitoring and improved the ability of monitoring.The original instrument and equipment have been updated and upgraded, continuous uninterrupted power supply system, data acquisition and transmission system performance have been greatly improved, observation environment has been effectively protected.Through the application of network technology, digital technology and new computer technology, we realized the data sharing, human-computer interaction analysis and positioning and save data disk medium, etc.software function, at the same time, the complexity of the network technology system also has a fundamental change.Through rediscussing the process of transformation and upgrading of the technical system of the digital seismic network of Jinchang area, combined with the network quickly and accurately to against south emperor city area in Gansu province in March 2008 a magnitude 5.0 earthquake and Qinghai Menyuan January 2016 magnitude 6.4 accurate positioning and earthquake quick report of an earthquake in the grid, providing a practical application of the data, in this article we will exchange the experience of the local area network transformation and explain its realistic significance of the transformation of the digital network.关键词
