The spiral high-speed door adopts a safety airbag, infrared photoelectric and grating protection system for the anti-collision system, which is safer and more reliable. The opening methods can include Bluetooth, geomagnetic induction, card swiping, license plate recognition, 24G induction probes, etc. Especially for concentrated entrances and exits, where there is a large volume of openings, strong wind pressure, and high environmental requirements, the requirements for the door body are extremely strict, and ordinary garage doors cannot meet these requirements.
