Problems solved by technology

All the above solutions can solve the trapping problem of the revolving automatic door to a certain extent, but they are all passive measures to reduce the risk when trapping occurs or will occur, and cannot actively solve the trapping problem of the revolving automatic door
In addition, due to factors such as sensor coverage, the existing revolving automatic doors are not safe enough, and are more likely to cause harm to petite children

Embodiment 1

[0075] Start the sensor settings like Figure 9 As shown, when any one of the start sensors 11, 12, 13, and 14 detects that someone enters the revolving automatic door, the control device sends a signal to start the motor, such as image 3 As shown, the operating method of the revolving automatic door according to the first embodiment of the present invention includes the following steps:

[0076] S1: Detect the position of the front end of the revolving door leaf, determine whether the front end of the revolving door leaf is located in the dangerous area, if so, execute S11, if not, execute S12; That is, outside the danger area and the deceleration area, execute S12;

[0077] S12: Start, accelerate the revolving door leaf to the normal speed, and then execute S2;

[0078] S2: The revolving door leaf runs at normal speed, then execute S3;

[0079] S3: Detect the position of the front end of the revolving door leaf, determine whether the front end of the revolving door leaf ...

Embodiment 2

[0088] like figure 1 , Figure 4 and Image 6 As shown, the difference between the second embodiment and the first embodiment is that the revolving door leaf operates at a safe low speed V 1 Running through the hazardous area, i.e. at a safe low speed V 1 Running 700mm, the front end of the revolving door leaf 900 reaches the right door frame, i.e. figure 1 At point B in the middle, the revolving door leaf 900 and the fixed door leaf 801 are closed, and pedestrians can no longer enter the revolving door. 1 Accelerate to normal speed V 0 , and at normal speed V 0 run until reaching the deceleration point just before the danger zone on the other side of the revolving automatic door, i.e. figure 1 At the point D1 shown, deceleration starts, and the above-mentioned process of deceleration, low-speed constant speed operation and acceleration is repeated. Every time the revolving door rotates once, the number of pulses is reset to zero, and a new cycle begins. Compared with ...

Embodiment 3

[0090] like Figure 7 As shown, the difference between the third embodiment and the first embodiment is that the following steps are added between S5 and S6:

[0091] Step S50 is executed after S5: it is judged whether the running speed of the revolving door leaf is greater than the threshold value, if so, execute S51, if not, execute S6;

[0092] S51: The revolving door leaf stops rotating.

[0093] As mentioned above, the operating speed V of the revolving door leaf is calculated according to the following formula:

[0094] V = πD N 0 × f

[0095] The size of the threshold can be based on the safety low speed V 1 to determine if a safe low speed V 1 105%, 110%, 115%, or 120%, etc.

[0096] According to the above operation method, when the revolving door leaf is running in the dangerous area, if an overspeed abnormality occurs, that is, when the speed of the...

Abstract

The invention discloses a rotary automatic door which comprises a fixed door leaf, a rotary door leaf, a driving device, a detecting device and a control device, wherein the driving device is used for driving the rotary door leaf to rotate, the detecting device is used for detecting the relative position of the rotary door leaf to the fixed door leaf, and the control device is connected with the detecting device and used for controlling the driving device to speed up, slow down or keep a uniform speed in accordance with the position of the front end of the rotary door leaf. The invention further discloses an operation method of the rotary automatic door. According to the rotary automatic door and the operation method of the rotary automatic door, the speed of the rotary door leaf of the rotary automatic door through a hazardous area is actively reduced, so that people in the hazardous area have enough time to move forward or backward, thereby greatly reducing the probability that the people are clamped by the rotary door leaf. When pedestrians or objects are detected by any danger sensor, the rotary door leaf can stop within a short braking distance, thereby reducing the impact force on the pedestrians or the objects, hurts to the pedestrians are minimized, and the pedestrians or the objects are guaranteed to exit in time.

Description

technical field [0001] The invention relates to the technical field of revolving doors in buildings, in particular to a revolving automatic door. Background technique [0002] Revolving automatic doors are widely used in public places such as hotels and restaurants because of their beauty and windproof advantages. According to the provisions of China Construction Industry Standard No. JG / T177-2005 "Automatic Doors": A revolving automatic door refers to two to four doors that are rotated around the central axis by signal control. The door body includes a fixed door leaf and a movable leaf. Among them, the fixed door leaf refers to the fixed and immovable part of the outer circumference of the revolving door in an arc shape. [0003] Chinese customs and regulations require pedestrians to walk on the right, so Chinese standards require that revolving automatic doors generally rotate counterclockwise. In the above-mentioned JG / T177-2005 standard, several terms are also specifie...
