摘要
针对CORS(continuously operating reference stations)基准站系统日常运维中存在一些基准站由于网络通信异常导致这些基准站不能正常提供服务的问题,提出了一种双网络结构的CORS基准站应急运维方案。该方案以无线(4G)网络为例,在基准站原有有线网络的基础上部署备用无线(4G)网络,形成有线网络为主、无线(4G)网络应急备用的双网络结构,在CORS控制中心数据流接入时,设计数据流接入智能代理机制,能够进行数据流智能网络切换。测试表明,该方案经济、高效,显著提高了CORS运维和服务能力,具有广泛的工程应用意义。
Aiming at the problems in daily maintenance of CORS(continuously operating reference stations)reference station such as abnormal network communication makes reference station unable to provide normal service,we propose an emergency maintenance scheme of CORS reference station with dual-network structure.In this scheme,taking 4G wireless networks as an example,besides intrinsic wired networks,we also put spare 4G wireless networks,thus makes a dual-network structure with wired network-oriented and 4G wireless networks aided.Meanwhile,when merging with central data stream,we design intelligent agent mechanism so as to switch data stream networks.Tests show that this scheme is not only economical and efficient,but also greatly improves CORS operation and maintenance ability,which has an extensive significance in engineering.
