description The utility model relates to a novel oil pumping unit intelligent monitoring device in the oil field oil extraction machine monitoring technology. The device comprises a flow trend monitor, a load meter, a pumping unit crank position sensor, a polish rod displacement converter and an indicator diagram synthesizer, wherein the flow trend monitor is arranged on an oil pumping gathering and transportation pipeline and used for monitoring the flow change trend on the oil pumping gathering and transportation pipeline, the load meter is installed on a polish rod of an oil pumping unit and used for measuring the load of the polish rod, and the oil pumping unit crank position sensor is installed on a crank shaft of the oil pumping unit and used for measuring the rotation angle of an oil pumping unit crank. The polish rod displacement converter is used for converting measured data of the pumping unit crank position sensor into displacement of a pumping unit polish rod, and the indicator diagramsynthesizer is used for
