UNDERWATER SENSOR NETWORK-BASED METHOD FOR DETECTING OIL LEAKAGE POINT OF OIL TRANSPORT PIPELINE AND MEASURING OIL LEAKAGE RATE

摘要

An underwater sensor network-based method for detecting an oil leakage point of an oil transport pipeline and measuring an oil leakage rate, comprising: arranging working nodes (4) and transfer nodes (2) of sensors around an oil transport pipeline (3), so as to establish a stereo sensor network; recording pressure and concentration values measured by the working nodes (4) of upstream and downstream sensors of the underwater oil transport pipeline (3), and comparing the pressure and concentration values with theoretical calculation values to determine whether the underwater oil transport pipeline (3) leaks; constructing a neural network model and training the pre-constructed neural network model; calculating the position of an oil leakage point by means of the trained neural network model; and according to the distance between the oil leakage point and a downstream sensor node, obtaining an oil leakage rate of the oil leakage point by means of a mathematical model. The method can improve the monitoring efficiency and monitoring reliability of an underwater stereo sensor network.
