The automatic Revolving door has a grand and luxurious design and good stability which the best choice for hotels, airports, shopping malls, hospitals, merchant halls, hotels, office buildings and other places. The design of automatic Revolving door is more complicated than other door types. How to ensure its smooth and safe operation is crucial. During the normal operation of the automatic Revolving door, there are more than 20 sets of sensors to ensure the normal operation of the machine. Automatic Revolving door intelligent safety anti-pinch system mainly includes infrared action sensor, anti-pinch contact sensing adhesive strip, infrared anti-collision stop sensor, infrared anti-collision deceleration sensor, infrared anti-pinch sensor and infrared middle automatic smooth door anti-pinch sensor.

1.Main hazardous area anti pinch sensor

The active infrared anti-pinch sensor GAS201 installed at the bottom of the canopy at the entrance and exit of the automatic Revolving door. The sensing angle is vertically downward. It starts to work when the distance between the arc door wing and the column is 500-600mm, and ends when the arc door wing passes through the column. When pedestrians or objects enter the sensing area, the revolving door stops running, effectively preventing pedestrians from getting caught; when pedestrians or other objects leave, the automatic Revolving door returns to normal operation

2. Contact type anti pinch sensor

In order to prevent the revolving door frame of the automatic Revolving door from pushing pedestrians during operation, contact type anti pinch sensors are installed in the anti-pinch rubber strips installed on the column of the revolving fan and the column on the right side of the entrance and exit. In case of encountering objects or pedestrians being pressed, the door leaf immediately stops rotating and reverses 60cm to prevent pedestrians from being hurt; The automatic Revolving door will return to normal operation until the rubber strip is returned to normal

3. Infrared anti-pinch sensor

In order to prevent the revolving door frame of the automatic Revolving door from colliding with pedestrians during operation, an infrared safety sensor is installed on the top of the revolving door canopy to form a downward emitting detection beam. When objects or pedestrians are detected between the door leaf and the column, the automatic Revolving door stops rotating immediately to prevent pedestrians from being crushed

4. Infrared photo sensor

The infrared photo eyes PT12 is located on the arc wing of the automatic Revolving door and the column of the exhibition box door, 685mm above the ground. When sensing pedestrians or objects (i.e. rays are blocked), the turnstile rotates at a slow speed; After troubleshooting, the rotary door will resume normal operation within 2 seconds. The other one is located at the bottom of the curved wing of the revolving door and on the exhibition box column, 85mm above the ground. When sensing pedestrians or objects, the automatic Revolving door will stop immediately.

5. Rotary wing anti-pinch foot sensor

The diffused type sensor PF50D is installed under the anti-pinch strip of the rotary wing. When pedestrians block the sensor beam, the automatic Revolving door will stop rotating to ensure the safety of pedestrians' feet and pets. When it is detected that pedestrians or pets have left, the automatic Revolving door resumes operation.

6.Column anti-pinch foot sensor

It is PF21B installed near the ground on the right side of the automatic Revolving door entrance and exit. When the curved wall of the revolving door exhibition box is moved to the right column 500-600mm, it starts to work. When the object is sensed, the revolving door stops. Ensure the safety of pedestrians' feet and pets, and use it in conjunction with the infrared anti-pinch sensor on the outer door pillar to eliminate sensing gaps and achieve protection for fellow travelers.
