| 摘 要： | 针对高精度位置服务平台现有业务特点以及异地多中心的发展布局，设计了一套适用于高精度位置服务平台异地多活运行模式的分布式架构方案，以解决主中心与分中心相对独立无法协同工作造成的资源浪费和业务冗余等问题，对高精度位置服务平台功能模块和平台架构分别进行了详细设计. 平台架构采用分而治之的设计思想对其进行分层设计，结合平台业务功能设计以及业务特点进行了相应的服务拆分与部署，解决了系统实现过程中分布式平台用户的服务获取、实时精密单点定位(RT-PPP)分布式处理和网络实时动态(RTK)分布式处理等关键问题，实现了与高精度位置服务平台相适应的高性能、高可用的分布式架构方案的设计，为平台的后续建设提供了有效的理论基础.

| Abstract: | In view of the business features and off-site multi-centre development layout of the high-precision location service platform, this paper designs a distributed architecture solution for a high-precision location service platform to solve the problems of resource waste and business redundancy caused by the relative independence of the main centre and the sub-center, which cannot work together. The functional modules and platform architecture of the high-precision location service platform are designed in detail in the paper. The platform architecture is designed in a hierarchical way using a divide-and-conquer design philosophy, and the services are split and deployed according to the business design and business characteristics of the platform, solving the key problems in the process of system implementation, such as user acquisition service for distributed platform, real-time precise point positioning (RT-PPP) distributed processing and network Real-time Rinenatic (RTK) distributed processing. The design of a high performance and highly available distributed architecture solution compatible with the high-precision location service platform is finally achieved, providing an effective theoretical basis for the subsequent construction of the platform. |
