Radar sensing principle of fast rolling door |
There are many ways to open the fast rolling door. The conventional ones are manual button switches and automatic induction switches. Automatic induction switches are also divided into: radar induction, infrared induction, geomagnetic induction, swipe card induction, etc., which can meet the needs of different environments. Today, we mainly introduces the induction principle of Suzhou fast rolling door.
The radar sensing in the automatic switch mainly relies on the sensor probe. It is like an eye. It senses pedestrians or moving objects through the probe, converts this signal into a passive dry contact short-circuit signal and transmits it to the fast rolling door controller, thereby realizing the automatic opening of the fast rolling door. If you want to be able to automatically turn on when vehicles pass by, but also to allow pedestrians to pass, then choose the radar sensing method.
Radar induction, also known as microwave induction, is based on the Doppler effect and adopts the most advanced planar antenna, which can effectively suppress the interference of high-order harmonics and other clutter, with high sensitivity, strong reliability, safety and convenience, intelligent energy saving, It is also a popular control method in the automatic induction of fast rolling doors. Each switch mode of Suzhou fast rolling door has its own unique advantages. In the actual use process, we can choose one or more combinations of control methods according to our needs, so as to achieve more convenient and fast use.
Places where different types of fast rolling doors are adapted And some workshops with high requirements for air cleanliness need to install zipper fast rolling doors. The track and curtain of the zipper fast rolling doors are completely attached to each other. Compared with ordinary fast rolling doors, the sealing performance of the zipper fast rolling doors Even better, the price of the zipper door is much higher than that of the ordinary fast rolling door, but the performance is really good. It has the function of anti-collision and automatic reset. The cost performance is still acceptable. Customers and friends can choose according to their own conditions.
Generally, there is wind pressure at the outdoor openings of the building. At this time, stacking fast rolling doors should be installed. Built-in steel pipes and aluminum alloy profiles can be added to the curtain of the stacking door, so that the wind pressure can be evenly distributed on the whole curtain, and the wind resistance effect Much higher than ordinary fast rolling doors, stacked fast rolling doors can be opened frequently and quickly, with good wind resistance, and are especially suitable for logistics channels and large-area outdoor doors. |
