摘要: 针对天然气脱硫净化装置空泡现象造成监测传感器数值异常波动而误预警问题,提出基于扩充时间卷积神经网络(ETCN)改进长短时记忆网络(LSTM)的多传感器数据融合技术,通过融合与空泡现象相关的多传感器数据进行发泡程序建模预测。结果表明:采用ETCN-LSTM网络模型能够准确融合多传感器数据并在时间维度上预测装置发泡程度,预测结果与真实值具有良好的拟合度;相比于LSTM网络,ETCN-LSTM网络模型预测结果的均方根误差(RMSE)和平均绝对误差(MAE)分别提升了12.0%和26.4%;同时,ETCN-LSTM网络模型的参数量保持较低水平,计算成本较低,提升了长期预测的稳定性。

Abstract: To address the false alarm issue caused by abnormal sensor fluctuations due to cavitation in natural gas desulfurization purification unit, this study proposes a multi-sensor data fusion technology based on an expanded time-convolutional neural network (ETCN) enhanced long short-term memory (LSTM) network. The ETCN-LSTM model integrates data from multiple sensors related to cavitation to predict foaming behavior. Results demonstrate that the ETCN-LSTM model effectively fuses multi-sensor data and accurately predicts foaming levels over time, with predictions showing strong alignment with actual values. Compared to the standard LSTM, the ETCN-LSTM reduces root mean square error (RMSE) and mean absolute error (MAE) by 12.0% and 26.4%, respectively, while maintaining low computational cost and improving long-term prediction stability.
