The invention provides a rolling door limiting control method, which relates to the technical field of rolling doors and comprises the following steps: S1, when a motor works, a controller acquires a real-time rolling door position value recorded by a Hall sensor in real time; s2, the motor is powered off, and the rolling door body is braked; s3, the controller stores the real-time position value of the rolling door finally obtained before the motor is powered off, and the real-time position value serves as a mark value; s4, the motor is powered on, and the controller obtains data of the Hall sensor again; and S5, the brake is released, and the real-time position value of the rolling door continues to be generated based on the mark value. The device is high in feasibility, suitable for the brushless motor rolling door with Hall induction, low in installation cost and capable of effectively recording the position of the rolling door during power failure, it is ensured that the position of the rolling door cont
