Since the continuous development of the manufacturing industry, the fast rolling shutter door has become a supporting door for the workshop. Many enterprises choose to install the fast rolling door. Its sealing, dustproof, dustproof, windproof, sound insulation and other characteristics are favored by the majority of enterprises, and it is beautiful in appearance and easy to clean. The door curtain can also be customized to be fully transparent, which is convenient for viewing the passage of forklifts inside and outside, and prevents people and vehicles from colliding. Next, I will introduce to you which intelligent opening methods are suitable for different installation environments of fast rolling shutter doors.

1. The radar opens an access door suitable for frequent entry and exit of forklifts and other vehicles and passage of people

Advantages: Fully automatic opening and closing, the door will automatically open as long as you enter the radar sensing area without human operation.

Disadvantages: As long as there is a moving object passing through the radar sensing area, the door will open automatically (referring to when the control handle is in the automatic gear position). When the control handle is in the manual gear position, the radar sensing does not work. At this time, there are only the operation buttons and the pull rope. switch, etc. to operate the door opening and closing).

2. Linkage interlocking type (double door interlocking): It is mostly used for workshop doors, workshop doors and access doors with higher dust-free levels. The automatic opening of the fast rolling door can be completed by connecting to the automatic trigger sensor device (such as radar, geomagnetic ring sensor, photoelectric induction, etc.).

3. Geomagnetic induction is turned on: (when the control box control handle hits the automatic gear position). As long as a metal object passes through the induction area of the geomagnetic induction coil (such as a vehicle or other equipment, a person pushes and pulls a metal car, etc.), the door can be automatically opened. The sensitivity of the geomagnetic ring sensor is adjustable.

Disadvantage: The door will not open when the person does not carry metal objects through the geomagnetic induction area. When the control handle is in the manual gear position, the geomagnetic induction does not work. At this time, only the operation button, pull rope switch, etc. operate the door to open and close.

4. Photoelectric induction opening: When people and vehicles pass through the photoelectric induction area, the control induction circuit receives the induction signal from the photoelectricity and instructs the quick shutter door to open

Advantages: No need for personnel to operate fully automatic opening and closing (referring to the control handle in the automatic gear position).

Disadvantages: The sensing range is small and can only be used as a safety sensing.
