The invention discloses a pumping unit positioning method and relates to the technical field of accurate positioning. In order to solve the technical problem in the prior art that the position of an oil pumping unit cannot be positioned due to the fact that the pixel position of a monitored and displayed image cannot be accurately registered with the actual position in an existing monitoring system, the technical scheme provided by the invention is as follows: the method for positioning the position of the oil pumping unit comprises the following steps of: acquiring a panoramic image; a step of collecting an orientation and a pitch angle corresponding to a target pixel point in the panoramic image; a step of obtaining the distance of the target pixel point according to the pitch angle corresponding to the target pixel point; obtaining latitude and longitude information of the target pixel point according to the distance of the target pixel point and the corresponding orientation; and matching the longitude and latitude information to the pumping unit corresponding to the target pixel point. The method can be applied to precise positioning and equipment management of the oil pumping unit in an oil field.

The invention belongs to the technical field of erosion monitoring and analysis, and particularly discloses a sandstone field composite erosion observation and quantitative analysis device which comprises a first runoff plot, a second runoff plot, a third runoff plot and a fourth runoff plot which are arranged side by side. The first runoff plot comprises a metal shell and a weighing assembly arranged in the metal shell; the second runoff plot comprises the metal shell and the weighing assembly, and a rain cover plate is arranged above the metal shell; the third runoff plot comprises the metal shell and the weighing assembly, and a transparent windproof plate is arranged above the metal shell; the fourth runoff plot comprises the metal shell and the weighing assembly, and a water-permeable and air-permeable layer is arranged above the metal shell. By adopting the sandstone field composite erosion observation and quantitative analysis device, the problems of insufficient single power monitoring, data processing limitation and poor field environment adaptability are solved.

This invention belongs to the field of bearing fault diagnosis and provides a bearing fault detection method and system based on deterministic learning and convolutional neural networks. The method includes acquiring a one-dimensional bearing vibration signal, expanding it into a two-dimensional signal using a high-gain observer, standardizing the two-dimensional signal to obtain a normalized signal, modeling the internal dynamics of the bearing vibration signal based on a deterministic learning mechanism, generating a dynamic information graph of the bearing vibration signal, and performing fault detection using a pre-trained convolutional neural network model based on the dynamic information graph to obtain the bearing fault detection result. This invention, for the first time from a dynamic system perspective, visualizes the dynamics of bearing vibration signals as a dynamic information graph and detects fault occurrence through changes in the dynamics.
