An intelligent monitoring system for hydraulic pipes based on multiple sensors

In hydraulic piping system, health management has become a challenging task. As operating in harsh environment, damage detection and fault diagnosis are important to hydraulic pipes. In this paper, an intelligent monitoring system is proposed for hydraulic pipes based on multiple sensors. Firstly, it collects and records various parameters of pipes such as vibration, hydraulic pressure, temperature, flow, and distributed strain at real-time. Secondly, comprehensive analysis on all data is implemented intelligently in the system, which includes natural frequency extraction, status detection, and fault alarm. Through kinds of experiments, the proposed system can evaluate pipe's health status quickly and efficiently.
