摘　　要：为了及时预警和减轻地震灾害的影响,建立地震预警系统至关重要。地震预警基准站是预警系统的基石和数据来源,基于VPDN、NQA等网络技术,设计了双链路热备的云南地震预警基准站链路传输模式,确保基准站数据稳定、快速地传输。通过实验验证,该系统具有较高的稳定性和可靠性,可以有效提高地震预警的准确性和时效性,并成功应用于云南区域预警基准站建设先行先试,为各省预警基准站通信链路建设提供参考。In order to timely warn and mitigate the impact of earthquake disasters,it is very important to establish an earthquake early warning system.The earthquake early warning reference station is the cornerstone and data source of the early warning system.Based on network technologies such as VPDN and NQA,this article designs a dual-link hot standby link transmission mode for the Yunnan earthquake early warning reference station to ensure stable and fast data transmission at the reference station.Through experimental verification,the system has high stability and reliability,which can effectively improve the accuracy and timeliness of earthquake early warning,and has been successfully applied in the construction of Yunnan regional early warning reference stations,providing reference for the construction of communication link of early warning reference stations in each province.
