The negative electrode 2 of the induction thermocouple cooperates with the positive electrode 4 of the induction thermocouple to determine the structural position of the rolling door body 1, thereby avoiding damage to the rolling door caused by overtravel during use.

[0034] The power supply rail 5 is used to supply power to the roller shutter group 3. The negative electrode 2 and the positive electrode 4 of the induction electric dipole located in the same vertical line ensure that there is no misalignment during the detection process, thereby ensuring the accuracy of positioning during the operation of the overall structure.

[0035] The rolling shutter group 3 is used to control the lifting of the rolling shutter door body 1, the power supply rail 5 is used to supply power to the rolling shutter group 3, and the positive electrode 4 of the induction couple located on the side of the rolling shutter group 3 facing the rolling shutter door body 1 cooperates with the negative electrode 2 of the induction couple to detect the position of the rolling shutter door body 1.

The two sides of the rolling shutter cylinder 31 are connected to one end of the rolling shutter chain 6, and the other end of the rolling shutter chain 6 is hinged to the bottom of the rolling shutter door body 1.

[0037] The shutter cylinder 31 cooperates with the driving device 33 to roll up and unroll the shutter chains connected on both sides, thereby controlling the shutter door body 1 to be lowered and raised.

[0038] like Figure 1 to Figure 2 As shown, as an optimization, the roller blind set 3 also includes a guide rail 34, the top of which is smoothly inclined upward toward the side where the roller is located, and the inclination angle is ninety degrees.

[0039] The guide rail 34 is used to guide the rolling door body 1 to guide the rolling door body 1 to rise and fall, and the side inclined plane is used to store the excessive rise of the rolling door body 1 to avoid damage to the rolling door caused by over-rolling.
