A Pipeline Monitoring System Based on Negative Pressure Wave and Wireless Sensor

摘要

Negative pressure wave positioning method is a technique for pipeline leakage detection and location, which is widely used in various fields. Wireless sensor technology has the advantages of low power consumption, easy networking and high positioning accuracy, which is the preferred technology for wireless location. This paper discusses a pipeline monitoring system based on negative pressure wave and wireless sensor. This system combines the advantages of high positioning accuracy, wide application range and small nodal volume. In order to prove the practicality, reliability and accuracy of this system, experimental results and comparison with other method are given, positioning error within 5%.
