Winding and unwinding system, control method, control unit, and computer storage medium

A winding and unwinding system for electrode plate, comprising:

• a winding and unwinding box, a cooling unit, and a control unit;
• wherein:
• the winding and unwinding box comprises a box body and a box door that jointly define a box space of the winding and unwinding box, an electrode plate discharge port provided on a side of the box body, a rotating shaft provided in the middle of the box space, an electrode plate cylinder connected to the rotating shaft and driven by the rotating shaft to wind or unwind the electrode plate, a first temperature sensor for monitoring temperature of the electrode plate, a first gas detector for monitoring oxygen concentration inside the winding and unwinding box, a gas inlet located at the bottom of the box body, and a gas outlet located at the top of the box body;
• the cooling unit communicates with the gas inlet;
• and
• the control unit controls the cooling unit to regulate the temperature of the electrode plate and the oxygen concentration inside the winding and unwinding box based on the temperature of the electrode plate and the oxygen concentration inside the winding and unwinding box.
