摘　　要：针对大规模数据采集系统中采集速率低、服务器负载过重以及数据节点网络地址不稳定等问题,提出基于多线程机制的电力数据采集系统设计方案。通过合理配置多个数据采集线程并发工作完成从多个数据节点采集实时数据,通过建立监听线程来保障系统与数据节点间通信连接的可靠性。最后从100个数据节点进行数据采集测试,取得1832条/min的数据采集速率和30 s左右的数据更新周期。结果表明该系统能够完成大规模网络的数据采集,拥有高效的采集速率,能够保证电力数据的实时性。In order to solve the problems in large-scale data acquisition system such as low acquisition rate, server overload on server and poor stability of data IP address, we propose a multi-thread mechanism-based electric power data acquisition system. Real-time data can be acquired from multiple data nodes by reasonably configuring the multiple data acquisition threads and working concurrently; the reliability of communication connection between the system and data nodes can be guaranteed through the establishment of a monitoring thread. Finally, an experiment of data acquisition from 100 data nodes is designed. The data acquisition rate is 1832 per minute and the data update cycle is 30 seconds approximately. Results show that the system can achieve efficient data acquisition in large-scale network with high acquisition rate, and can guarantee the electric power data to be real-time.
