Distributed Monitoring System for Resident Electric Leakage Protection

为减少故障排查与修复时间,有效降低漏电伤亡事故,提高用电安全,研发了居民漏电保护分布式监控系统。给出了居民漏电保护监控系统的网络结构和系统功能体系,创新性地提出了基于国家电网通信标准的两级负载均衡策略构建多入口、网络I/O与业务分离的低成本分布式终端服务集群的方法,并给出了负载均衡算法。详细阐述了设备实时监控请求和终端服务两个关键服务进程的设计方法。测试与运行结果表明,文中设计的分布式监控系统能够满足居民漏电保护监控所需的高并发与实时响应要求。

In order to reduce the time of troubleshooting and restoration to effectively reduce electric leakage casualty accidents and improve power safety,a distributed monitoring system for resident electric leakage protection is developed.The network structure and function system of resident electric leakage protection monitoring system are given.It is proposed creatively,based on two-level load balancing strategy of the national power grid communication standard,to construct the method of low-cost distributed terminal service cluster with multiple entrances and separation between network I/O and services,and a load balancing algorithm is given.The design methods of two key service processes,equipment real-time monitoring request and terminal service,are described in detail.The test and operation results show that the distributed monitoring system designed in this paper can meet the requirements of high concurrency and real-time response for resident electric leakage protection monitoring.
