输油管线漏失动态监测系统设计及实现

Design of a dynamic monitoring system for oil pipeline leakage and its implementation

输油管线漏失动态监测系统通过在输油管线两端实时监测管线内压力场的变化 ,根据水击波在管线内的传播特性 ,分析管线的运行状态 ,判断是否有漏失发生并报警 .介绍了基于水击波原理的输油管线漏失动态监测系统的工作原理、功能模块、硬件组成和软件工作流程 .现场试验证明该系统工作可靠 。

The system can real-time monitor the leakage of a pipeline by monitoring the change of the pressure inside a pipeline at both ends of the pipeline. The working state of the pipeline is analyzed and whether and where the leakage occurred is judged according to the characteristics of water hammer wave propagation. The system can sound the alarm when the leakage is detected. The operating principle, functional modules, hardware constitution and software flow charts of the system are described. Field tests show that the system works reliably.
