Abstract：In order to solve the problems of the beam pumping machine with high cost，high power consumption，low efficiency，difficult adjustment and other issues，and comparative analysis of the advantages of intelligent control of upright model oil pumping machine，theupright model oil machine would instead of a beam pumping machine which work into the practice. The high reliability of upright model oil pumping machine was analyzed，and the intelligent control method of adaptive frequency control and automatic method for system fault diagnosis was realized by using Siemens PLC and Micromaster converter，which the control system through the use of Siemens PLC as the core controller to control the inverter operation frequency，by changing the motor，real-time calculate the speed of pumping unit，and through calculate the up and down stroke time to control the frequency and voltage output power of the inverter. The stepless speed regulation control of motor was achieved，to fit the operation torque. The results indicate that，he intelligent control system of the energy saving of upright model oil pumping machine has the advantages of simple structure，long life of free trouble operating，and has remote monitoring interface etc..
