s2, automatically controlling the telescopic rod to carry out angle correction by the controller;
s3, automatically controlling the telescopic rod to carry out vertical direction correction by the controller;
s4, automatically controlling the controller to correct the telescopic rod in the horizontal direction;
and S5, the controller automatically controls a breaker in the hydrogen production control switch cabinet to close to supply power to the PEM hydrogen production equipment so as to produce hydrogen.
4. A method as set forth in claim 3, characterized in that a protection device is provided in the PEM hydrogen production coupling device, which cuts off the power supply to the PEM hydrogen production coupling device when the power supply fluctuates beyond a voltage, current or frequency limit.
