摘要
介绍了一种采用虚拟仪器技术构建的输水管道泄漏监测系统的设计和实现.重点讨论了泄漏监测系统的泄漏定位方法、硬件设计和在LabVIEW环境下的软件模块化设计.对于突发的输水管道泄漏,综合运用了包括小波分析在内的多种信号处理方法,能够及时准确地定位泄漏点.实践证明这种基于LabVIEW的输水管道泄漏监测系统具有很强的灵活性和可扩展性.
This article introduces the design and implementation of a delivery pipeline leak monitoring system based on virtual instrument, especial the leak location method, hardware design and software module design under LabVIEW of the system. Several methods of signal processing, including wavelet analysis are utilized. The system can exactly locate the leak point in time to abrupt water leakage. Practical application proves that the system possesses strong flexibility and expandability.
