Method for detecting oil leakage point and oil leakage rate of oil pipeline based on underwater sensor network

Abstract

The invention discloses a method for detecting an oil leakage point and an oil leakage rate of an oil pipeline based on an underwater sensor network. The method comprises the following steps of: correspondingly arranging working nodes and transfer nodes of sensors around the oil pipeline, and establishing a three-dimensional sensor network; recording pressure and concentration values monitored bythe working nodes of the upstream and downstream sensors of the underwater oil pipeline, judging whether the underwater oil pipeline leaks or not by comparing the pressure and concentration values with theoretical calculation values, and constructing a training set to train a pre-constructed neural network model; calculating the position of the oil leakage point through the trained neural networkmodel; and solving the oil leakage rate of the oil leakage point through a mathematical model according to the distance between the oil leakage point and the downstream sensor node. The method disclosed by the invention can improve the monitoring efficiency and reliability of the underwater three-dimensional sensor network.

Problems solved by technology

[0004] At present, although the sensor network can be applied under the water surface, it still has the problem of low judgment accuracy when monitoring oil spill points underwater; in addition, it also has low reliability for complex and variable underwater environments. Defects

[0005] To sum up, the current method cannot monitor the changes of the underwater oil pipeline well to a certain extent. A new detection method based on the underwater sensor network for the oil leakage point and oil leakage rate of the oil pipeline is continued.
