【Abstract】 At present, the beam pumping unit is widely used in domestic oil fields. Howerer, the accuracy and reliability cannot be considered simultaneously when diagnosing the working conditions of the pumping units. To deal with this problem, a new method of measuring the indicator diagram of the beam pumping unit is proposed. With this method, the displacement within a complete working period can be calculated based on the mechanical structure and the kinematic equations of the pumping machine, and the results of the displacement are stored to the cloud server. The acceleration data and the load data are collected synchronously by using the acceleration sensor and the load sensor. Through mean filtering of the acceleration data, the load data in a single complete cycle is intercepted and uploaded to the cloud server, and the indicator diagram of the pumping unit is drawn with cloud computing. Experiments show that this method is superior to the existing methods, and it has the advantages of high accuracy, high reliability, easy installation and maintenance, and low cost.更多还原
