Using the pattern recognition ability of the neural network, the working condition diagnosis mathematical model has been established, adopting the improved BP neural network. And through preference to the network’s architecture, good convergent effect has been received.
通过理论分析和对大量实际生产数据进行对比整理,选取能够正确反应螺杆泵井工作状态的状态参量(产量、动液面、电机输入功率)作为工况诊断的特征向量;总结了螺杆泵井常见的几种工况,作为工况诊断的目标向量;利用神经网络的模式识别能力,采用改进的BP神经网络建立了螺杆泵井工况诊断的数学模型,并优选神经网络结构,使其具有较好的收敛效果。
