This paper proposes a control scheme based on the CANopen communication protocol for subsea valve motors control.The technology and characteristics of the CANopen communication protocol are briefly introduced,and the execution process of the motor driver state machine is studied in depth.The hardware structure,communication structure and main station software control flowchart of subsea valve motor control are designed in detail.The upper and lower computer for subsea valve motor control is programmed and verified through the construction of a test bench.The experimental results show that the use of CANopen communication can achieve precise control of subsea valve motors.The control network operates quickly,conveniently,stably,reliably,with good real-time effects and smooth data exchange,which can meet the requirements of subsea valve motor control and improve control performance.
