Design of Topology Network Structure Recognition in Digital Repeater System

数字多点系统的数字特性允许系统拓展多级设备以扩大信号覆盖面积,拓展级联的引入增加了整个系统拓扑结构的复杂性,进而增加了远程监控的难度。针对几种常用拓扑结构,设计并实现了数字多点系统的拓扑网络动态实时识别方案,并给出了拓扑网络的结构和拓扑动态识别的工作过程。大量实验验证表明本设计可以提高拓扑网络识别的可靠性和稳定性,为网管中心监控路径搜索奠定了基础。

The characteristics of digital repeater systems allow the system to cascade connect lots of sub- equipment to expand the signal coverage area. But the expanding scheme will increase the complexity of the entire topology structure, further increase the difficulty of monitoring from remote operation and maintenance center（OMC）. This paper designed and implemented a dynamic identification scheme based on real-time operating system and FPGA （Field Programmable Gate Array ）combination, real-timely identifying the network topology changes in the system and providing to the OMC. This paper analyzed the possible topology structure and illustrated the process of the dynamic topology recognition. This design can help improve the reliability and stability of the recognition process, lay the foundation for the path search monitoring from OMC.
