Abstract The surge protective devices（SPD）are managed in multistage grouping management according to the geographic locations；N-tree data structure is adopted in the computer algorithm design. Based on this structure，the multi-threading mechanism is introduced for real-time polling of SPD running status so as to improve the efficiency and reliability of the lightning monitoring early warning system.

Key words　SPD Monitoring system Multistage grouping management Multi-threading mechanism N-tree Depth-first traversal

摘　要　按照地理位置进行多级分组管理 SPD（浪涌保护器），在计算机算法设计中采用 N 叉树的数据结构，基于此结构，引入多线程机制实时轮询 SPD 运行状态，提高了防雷监控预警系统的效率和可靠性。
