The invention discloses a modern intelligent pumping unit, relates to oil exploitation equipment and aims to provide a reducer-free series combined transmission pumping unit which uses the Internet+ without sensors, provides big data provided during driving of a servo controller and automatically regulates, controls and diagnoses the downhole liquid level and operation parameters through an expert analysis system. The modern intelligent pumping unit comprises an integrated driving system composed of a tower, a control system, a power system, a transmission system, a balance weight system, a counter weight pulling rope, a rope sheave, a driving rope, a beam hanger and a well repair yielding mechanism, a steel wire rope wound and fixed to the rope sheave is driven to move up and down, and thus oil exploitation operation is completed. Through the modern intelligent pumping unit, the problems of uneven stress of a whole unit and high amplitude due to the fact that a transmission system of an electronic control reversing pumping unit is centralized on one side of a platform are solved, the problems of high fault rate of reducers, high maintaining cost and cost and low stability are solved, the application range is enlarged, and the purpose that all types do not need to be overhauled is achieved; and the well repair yielding mechanism is safe and convenient to use.
