[0002] The beam pumping unit is an important machine mining equipment in the process of oil extraction in the oil production plant. The beam pumping unit often stops due to sudden failure, or the well is stopped for a long time in winter, which is easy to cause the wellhead pipeline to be frozen and blocked. Since the beam pumping units in the oil field are widely distributed, the distance between each beam pumping unit site is far apart, and the distance interval between any two beam pumping units is very far apart. The oil extraction workers are responsible for a large number of oil wells, and it takes several hours to completely patrol the oil wells they are responsible for every day. The manual labor intensity is large. Therefore, for the oil wells that stop due to sudden failure, it is not possible to timely and effectively handle them in a targeted manner. During the day, the far distance fault well can be discovered when the beam pumping unit is stopped, but due to the poor visibility at night, the fault well cannot be discovered and handled in time, and the shutdown time is prolonged. The discovery is often delayed, which greatly affects the crude oil production and seriously affects the opening efficiency of the crude oil production.
