摘　　要：随着我国配电自动化的快速发展,传统配电采集模型不能满足大规模配电终端实时采集需要,配电网大数据采集成为了大型配电主站一项关键技术。通过对Linux epoll机制的特点进行分析,设计了一种处理海量网络通信信息处理模型,结合多线程同步和数据访问机制问题,研究了基于epoll机制C/S模式的设计模型和实现步骤。在存在大规模客户端、服务端类型的配电终端的应用场合,保证了配电信息采集的时效性和安全性。With the rapid development of distribution automation in our country,the traditional distribution collection model cannot meet the demand of large-scale real-time massive power distribution terminal. Power distribution network data acquisition has become a key technique of large-scale distribution master station. Analyzing the characteristics of Linux epoll mechanism,we design a magnanimous networking communicating information processing model which combines multithreaded synchronization and data access mechanism. It studies the model design and the implementation of epoll mechanism under C/S model. It guarantees the timeliness and safety of distribution information whenthere is large scale of clients and service terminal type distribution terminal.
