P2P技术应用于SCADA/EMS的探讨

在分析了目前国内监控与数据采集/能量管理系统(SCADA/EMS)的结构以及网络数据安全状况的基础上,结合现代计算机网络技术,提出在SCADA/EMS中采用对等网(P2P)技术的分布式计算模式。该计算模式通过利用主站内的快速网络资源、后台节点闲置的CPU周期以及多余内存等资源,以达到增强整个SCADA/EMS的数据处理能力、进一步提高SCADA/EMS实时性和可靠性的目的。此外,该计算模式采用了P2P技术,虽然只是升级了旧系统的后台机性能,但仍可较好地改善整个系统的性能,使得整个SCADA/EMS获得较好的扩展性。

Discussion on the Application of P2P Technology in SCADA/EMS

Based on an analysis of the structure of domestically used SCADA/EMS system and the security of the network data as well as the application of the modern computer network technology, a distributed calculating mode adopting the peer-to-peer (P2P) technique in SCADA/EMS is put forward. By utilizing the fast network resource in the main station, the CPU cycle left unused and the surplus memory of backstage workstation, the calculating mode is enabled to enhance the data processing capability of the whole SCADA/EMS and further improve its real-time character and dependability. Although the P2P technique is only used to update the old system of the backstage workstation, the performance of the whole SCADA/EMS is also improved and will be easily expanded.
