| 摘 要： | 为了解决目前的输油管道泄漏监测和定位问题，提出了一个基于虚拟仪器的输油管道泄漏监测定位系统的实现方法。其采用了因特网来传输数据，提出了基于负压波和流量平衡法的四段法判断泄漏，分析了负压力波传到首末两站的时间差对泄漏定位的影响以及使用小波变换检测时间差的方法。系统在实际应用中取得了良好的效果。

| Abstract: | To solve the problem of oil pipeline leak monitoring and location, a method for implementation of oil pipeline leak monitoring and location system based on virtual instruments is presented. Data is transferred through the Internet. A four-sect method basing on the negative pressure wave and flow equilibrium theory is presented to detect pipeline leak. The influence of the time difference between the time when the negative pressure wave arrive at the start of pipeline and the time at the end of pipeline on leak location and the method to get the time difference through wavelet transform is analyzed. The system works well in practice. |
