The structure of pumping unit layer of the remote supervisory and control system for well pumping unit is researched. A new kind of the pumping unit layer is presented,which has the characteristic of integrating the saving energy controller of pumping unit and the remote supervisory and control system. Firstly,the overall structure of the remote supervisory and control system for well pumping unit is designed. Next,the hardware structure and the software structure of the pumping unit layer are analyzed in detailed. The hardware system of pumping unit layer includes closed loop real-time control system of saving energy for pumping unit and the data supervisory and transmission system. And the software system is comprised of intelligent controller based on neural network and the data sampling and supervisory software system. Finally,the experiment for the pumping unit layer shows that the data can be transmitted reliably and efficiently,and the energy saving for pumping unit can be realized.
