基于PSO-FCM的长输管道泄漏检测方法

为了提高长输管道泄漏检测的准确率,将改进模糊C均值算法应用于长输管道泄漏检测研究.在传统模糊C均值算法的基础上引入粒子群算法,对其寻找聚类中心的迭代过程进行优化,用粒子群算法替代模糊C均值的梯度下降法,以提高模糊C均值算法的聚类效率和准确率.然后分别用所得的基于粒子群优化的模糊C均值聚类模型、传统模糊C均值聚类模型以及3层BP(Back Propagation)神经网络分类模型对同一组管道泄漏检测实验数据进行处理.对比实验结果证明,基于粒子群优化的模糊C均值算法其性能优于传统的模糊C均值算法和3层BP神经网络,将其模型应用于长输管道泄漏检测的方案可行.

Novel Detection for Long-Distance Pipeline Leakage Based on PSO-FCM

In order to improve the accuracy and efficiency of leakage detection for long-distance pipeline, the modified fuzzy C-means algorithm is applied. Particle swarm optimization algorithm is introduced to optimize the troditional fuzzy C-means algorithm, which is used to represent the gradient descent so as to improve the efficiency and accuracy of fuzzy C-means algorithm. Then the proposed fuzzy C-means algorithm is used to analyze the same group of pipeline leakage experimental data compared with troditional fuzzy C-means algorithm and 3-layer BP (Back Propagation) neural network. The result proves that the proposed fuzzy C-means algorithm has a better property than the other two algorithms, so it is feasible to apply the PSO-based Fuzzy C-Means model in pipeline leakage detection.
