Abstract
A leakage detection method for a long petroleum pipeline based on AFPSO-K-means includes: initializing a particle swarm, and defining an initial velocity and an initial position of each particle in the particle swarm; determining a fitness value of the each particle; traversing the fitness value of the each particle to obtain an optimal position corresponding to the fitness value of the each particle and a global optimal position in optimal fitness values of the particle swarm; iteratively updating a velocity and a position of the each particle based on the optimal position corresponding to the fitness value of the each particle; and when a distance from the position of the each particle to the global optimal position is less than a preset threshold or a number of iterations reaches a preset value, outputting a current iteration updated result to determine an actual leakage position of the petroleum pipeline.
