[Software Engineering] acceleration-signal DL : 0: 利用加速度信号测量位移是油田抽油井光杆位移测量的主要方法而加速度信号的随机噪声和趋势项是影响测量精度的主要因素本文提出了一种基于学习的实时消噪和剔除趋势项方法学习时先获取一段时间的加速度信号再通过时间序列分析技术得出 ARIMA 模型及其参数最后基于 FFT 变换的 Rife-Jane 频率估计方法求出加速度信号的周期在线实时消噪和剔除趋势项方法是基于学习阶段所得模型参数运用卡尔曼滤波技术消除加速度信号随机噪声按周期两次积分得到光杆位移用加窗递推最小二乘法在线消除趋势项通过抽油机半实物仿真平台测试和分析加速度信号结果表明该方法有效地去除了加速度信号中的噪声和趋势项极大地提高了位移的测量精度-Acceleration signal based approach is a main approach used to measure the displacement of polish rod in the oilfield pumping wells. In this study a learning based real time noise immunization and trend term elimination approach is proposed. During the learning acceleration signal within a period of time are firstly acquired then corresponding ARIMA model and its parameters are derived finally the period of the acceleration signal is computed by using FFT transformation and Rife Jane frequency estimation. The proposed approach bases the model obtained parameters uses Kalman filtering techniques to remove random noise computes the polish rod displacement by a quadratic integration of the period and eliminates the trend term by windowed recursive least squares method. Eventually an experiment over a pumping unit hardware in the loop plant is carried out which indicates that the proposed approach can effectively eliminate noise and trend term and obviously improve the measuring pre
