Design and Development of Intelligent Control System forNew Autobalance Beam Pumping Unit

Aiming at the problem of difficult balance adjustment and low intelligent level in traditional beam pumping unit,the intelligent control system of the auto balancing beam pumping unit based on STM32 is designed and developed in order to improve the balance rate and the efficiency of the motor power.The traditional method of current balance and average power method are integrated.What's more,this paper presents a method of auto balance adjustment based on minimum power,which can meet the demand of energy saving adjustment to adapt to the changing conditions.The host computer monitoring software can be used to display data,store data and send commands.The field test of the system shows that the accuracy and stability of data collection.It is also proved that the system can realize the auto balance adjustment of the auto balance beam pumping unit effectively and reduce the loss of the mechanical system of pumping unit which has great application value.
