摘要
针对公众的高精度位置服务需求与CORS高精度定位一直局限于极少数行业(如控制、测图等)的矛盾问题,融合物联网、云计算、大数据等技术,探索基于CORS的位置服务云平台架构设计及CORS高精度、高并发技术方案。通过构建格网化的高精度位置差分池,实现了高精度、高并发的位置云服务。搭建的Demo云平台服务测试表明:系统运维效率提高2.6倍以上,有效用户并发量达5万以上,CORS云服务的网络RTK/RTD成果服务精度无损。
According to the contradiction between public requirements of high-precision location and the limited application of CORS high precision positioning such as surveying and mapping,the design of cloud platforms based on CORS location service,and high concurrent access were introduced,by integrating with internet of things,cloud computing,big data and artificial intelligence.A high precision location differential pool was constructed by grid transformation,so that high currency access and high precision position can be realized in cloud.The cloud platform service tests suggest that,the system operation efficiency increases at least 2.6 times,the number of current users achieves at least 50 thousand,and the internet RTK/RTD of CORS cloud service is non-destructive in precision.
