长输油管道泄漏检测与定位的网络控制系统

Detection and location of long oil pipeline leakage by network control system/

网络控制系统具有结构网络化、节点智能化、控制现场化、功能分散化、系统开放化和产品集成化等特点.局域网络控制系统的优点是减少系统的接线,使系统容易诊断和维护,增强系统的灵活性.将局域网络控制系统应用于长输油管道泄漏检测与定位,并给出了软、硬件的实现.该系统应用于一段输油管道上,效果较好,可以拓展到多段管道的泄漏检测与定位.

The network control has many characteristics, frame network of node, intelligence of node, locale of control, decentralization of function, dispark of system, integration of product, and so on. The network control has many virtues, with less connection, easy diagnosis and maintenance, agility of buildup. This paper introduces the network controls of leakage detection and localization of the system of the pipeline. It is realized and the software and hardware are presented. The method is used in a section of pipeline oil transport, with satisfactory results. It may be used to more sections of oil pipeline transport for leakage detection and location. The application prospect is promising.
