Abstract
A control system recording in real time and controlling an oil pumping unit posture relates to the oil pumping unit control field. By using the system of the invention, problems that machinery adjustment is mainly operated manually; adjusting time is long; a response speed is slow; oil extraction working can not performed normally so that oil extraction efficiency of the oil pumping unit is low are solved. An angle sensor of the control system is fixedly installed on a frame fulcrum of the oil pumping unit and is used for detecting a pendulum angle of a sucker rod and sending a detection signal to an alternating current servo control system. A control signal output terminal of the alternating current servo control system is connected with a control signal input terminal of a synchronization motor. A three phase current detection signal input terminal of the synchronization motor of the alternating current servo control system is connected with a three phase current detection signal output terminal of the synchronization motor. A motor encoder is used for detecting a rotor position of the synchronization motor, a rotor rotating speed and a rotor direction. A power output terminal of the synchronization motor drives the sucker rod to swing through a transmission mechanism. The system of the invention is suitable for controlling the swing of the sucker rod of the oil pumping unit.
