基于离散小波分析的地下金属管线测量精度控制方案

Measurement accuracy control scheme of underground metal pipeline based on discrete wavelet analysis

传统金属管线测量精度控制因采用模糊处理,导致控制误差较大。为此,研究基于离散小波分析的地下金属管线测量精度控制方案。使用离散小波分析对测量信号进行分析后,建立目标函数并利用神经网络求解。求解值将作为精度控制的输入参数实现精度控制。通过实验,验证了基于离散小波分析的控制方案精度高、可靠性更佳。

The traditional metal pipeline measurement accuracy control adopts fuzzy processing,which leads to large control error.Therefore,the control scheme of underground metal pipeline measurement accuracy based on discrete wavelet analysis is studied.After the measurement signal is analyzed by discrete wavelet analysis,the objective function is established and solved by neural network.The solution value will be used as the input parameter of precision control to realize precision control.The experimental results show that the control scheme based on discrete wavelet analysis has high precision and better reliability.
