Specifically, in order to solve the technical problems that the prior roller shutter door cannot be suddenly stopped and the mechanical structure is damaged due to fatigue, in the normal working process of the roller shutter door, the driving rod 13 is driven by the lifting driving mechanism 15 to rotate, the driving rod 13 drives the curtain sheet 2 to lift through the belt of the driving component, the curtain sheet 2 enters the winding rail 12 along the linear rail 11 to complete the winding process, in the process that the roller shutter door needs to be closed, the tension spring 3 pulls the rope belt 4 through the connecting plate 31, the rope belt 4 wound on the driving rod 13 starts to unwind, and the driving rod 13 also rotates simultaneously, the driving rod 13 reversely drives the curtain sheet 2 to descend through the belt wheel component 14, in the descending process of the curtain sheet 2, the lower part of the curtain sheet 2 and the two sides of the curtain sheet 2 are detected in real time through the infrared sensor and the microwave sensor arranged on the bottom beam 21, when the microwave sensor monitors the moving targets appearing on the two sides of the curtain sheet 2 in real time, in the process that a moving target gradually approaches the curtain sheet 2, the microwave sensor sends a signal to the controller, the controller controls the flow passing through the speed regulating valve 64, the connecting plate 31 is also pulled by the tension spring 3 to descend in the descending process of the curtain sheet 2, the connecting plate 31 descends to drive the piston head in the piston cylinder 62 to descend, the gas in the piston cylinder 62 is discharged through the gas outlet, the controller reduces the speed regulating flow to cause the gas in the piston cylinder 62 to be slowly discharged, so that the descending speed of the connecting plate 31 pulled by the tension spring 3 is delayed, the descending speed of the curtain sheet 2 is slowed down to ensure that the curtain sheet 2 can be quickly stopped at any time, when the moving target moves to the bottom of the curtain sheet 2, the infrared sensor on the bottom beam 21 immediately detects the appearance of a shielding object, and sends a signal to the controller, the controller opens the locking mechanism 5, the locking driving component 53 fixes the fastening wheel 52, the fastening wheel 52 and the guiding wheel set 51 are engaged with each other to pass through the notch 41 on the rope belt 4, so the guiding wheel set 51 stops rotating at the same time when the fastening wheel 52 stops rotating, thereby the rope belt 4 stops moving, the rope belt 4 stops moving through the control of the notch 41, when the control of the notch 41 is realized, the rope belt 4 stops moving completely, and the precise control of the rope belt 4 is improved by controlling the density of the notch 41 arrangement, thereby the curtain sheet 2 stops rapidly and precisely, when the curtain sheet 2 does not have the microwave sensor to detect the approach of the moving object in the descending process, but the infrared sensor detects the shielding object, the descending of the curtain sheet 2 needs to be stopped rapidly, the buffer mechanism 6 cannot intervene directly, because the curtain sheet 2 does not have the buffer mechanism 6 to decelerate, therefore, if the locking mechanism 5 suddenly stops the movement of the rope belt 4, the curtain 2 will transmit the reaction force to itself and a series of connection structures such as the belt wheel assembly 14 under the action of inertia, which causes great fatigue damage to many mechanisms, in order to avoid this situation, the controller simultaneously opens the locking mechanism 5 and the anti-falling control mechanism 7, adjusts the air outlet path of the piston cylinder 62 through the electromagnetic directional valve 65, the compressed and exhausted air inside the piston cylinder 62 will be directly injected into the airtight space inside the guide wheel 71 of the anti-falling control mechanism 7, specifically, the air flow is injected into the air bag 73, the air bag 73 starts to expand and pushes a plurality of expansion plates 72 to radially extend from the inside of the guide wheel 71 to the outside thereof, the extended expansion plates 72 are clamped between the tooth grooves of the linear rail 11, and the movement stop of the bottom beam 21 of the curtain 2 is completed, and the locking mechanism 5 stops the continuous movement of the rope belt 4, the rapid emergency stop operation of the curtain sheet 2 is completed under the dual control, and the sole beam 21 of the curtain sheet 2 is independently controlled in the emergency stop process, and the impact force is directly transferred to the linear rail 11 of the frame body 1, so that the overlarge impact force of a transmission mechanism with poor impact resistance is avoided.

Specifically, in order to solve the technical problem that the conventional stopping method for directly clamping the side wall of the fastening wheel 52 is easy to slip, the controller starts the linear actuator 534, the linear actuator 534 pushes the movable rod 532 to move, one end of the movable rod 532 pushes the sliding member 5353, the sliding member 5353 overcomes the pre-tightening force of the first spring 5354 to gradually approach the bottom end of the guide housing 5351, the sliding member 5353 drives the two clamping rods 5355 to move along with the sliding member 5353 in the moving process, the stressed ends of the two clamping rods 5355 overcome the pre-tightening force of the second spring 5356 to continuously approach each other under the guiding of the slope surface of the inner wall of the guide housing 5351, and finally the output ends of the two clamping rods 5355 simultaneously clamp the movable rod 532, the gear 531 cannot rotate after the movable rod 532 is fixed, the fastening wheel 52 cannot rotate after the gear 531 is fixed, and the fastening wheel 52 needs to pass through the notch 41 on the rope belt 4 due to the mutual engagement between the fastening wheel 52 and the guide wheel set 51, so that the guide wheel 51 stops rotating when the fastening wheel 52 stops, and the rope belt 4 stops moving.
As shown in fig. 11 to 12, the following preferred technical solutions are provided:
Specifically, in order to solve the technical problem of how to delay the descending speed of the curtain sheet 2, the connecting plate 31 is also pulled by the tension spring 3 to descend in the descending process of the curtain sheet 2, the connecting plate 31 descends to drive the piston head in the piston cylinder 62 to descend, the gas in the piston cylinder 62 is discharged through the small holes, and the gas in the piston cylinder 62 is slowly discharged due to the limited gas inlet and outlet amount of the small holes, so that the descending speed of the connecting plate 31 pulled by the tension spring 3 is delayed, the descending speed of the curtain sheet 2 is slowed down, the phenomenon that the descending speed of the curtain sheet 2 is too high is avoided, and the small-bore flow of the small holes cannot be influenced when the piston cylinder 62 admits gas due to the relatively slow descending speed of the curtain sheet 2 in the ascending process.
As shown in fig. 11 to 12, the following preferred technical solutions are provided:
Specifically, in order to solve the technical problem how to delay the descending speed of the curtain sheet 2, because the connecting plate 31 of the curtain sheet 2 is also pulled by the tension springs 3 to descend in the descending process, the connecting plate 31 descends to drive the piston head in the piston cylinder 62 to descend, the gas in the piston cylinder 62 is discharged through the gas outlet, and because the difference exists between the different tension springs 3 in elasticity, the descending speeds of the curtain sheets 2 of different roller shutter doors are finally inconsistent, and the gas outflow speed in the piston cylinder 62 can be limited from being changed under the influence of loads by arranging the speed regulating valve 64 in the gas outlet, so that the gas in the piston cylinder 62 is controlled to slowly flow out at the consistent speed.
