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 setup like Figure 9 As shown, when any one of the start sensors 11, 12, 13, 14 detects that someone enters the revolving automatic door, the control device will send a signal to the motor to start, as image 3 As shown, the operating method of the revolving automatic door in Embodiment 1 of the present invention includes the following steps:

[0076] S1: Detect the position of the front end of the revolving door leaf, and judge whether the front end of the revolving door leaf is in a dangerous area, if yes, execute S11, if not, execute S12; in this embodiment, since the revolving door leaf is in the initial position when starting, That is, outside the dangerous area and deceleration area, execute S12;

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

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

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

Embodiment 2

[0088] Such as figure 1 , Figure 4 with Image 6 As shown, the difference between Embodiment 2 and Embodiment 1 is that the rotating door leaf rotates at a safe low speed V 1 Running through the dangerous area, that is, 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, the revolving door leaf 900 is closed with the fixed door leaf 801, 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 before the danger zone on the other side of the revolving automatic door, i.e. figure 1 The point D1 shown starts to decelerate, and repeats the above-mentioned process of deceleration, low-speed constant speed operation and acceleration. Every time the revolving door leaf rotates once, the pulse number is reset to zero, and a new round of cycle begins. Compared with the first embodiment, the a...

Embodiment 3

[0090] Such as Figure 7 As shown, the difference between Embodiment 3 and Embodiment 1 is that the following steps are added between S5 and S6:

[0091] Execute step S50 after S5: determine whether the operating speed of the revolving door leaf is greater than the threshold value, if yes, execute S51, if not, execute S6;

[0092] S51: the rotating door leaf stops rotating.

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

[0094] V = πD N 0 × f

[0095] The magnitude of the threshold can be determined according to the safe low speed V 1 to determine, as for 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 th...

Abstract

PROBLEM TO BE SOLVED: To provide a highly safe automatic revolving door that quickly stops rotary wings, largely reduces impact force and allows an escape of a passerby and an object to be secured at the time of detection of any danger detection sensor when rotary wings leading end portions enter dangerous areas and the passerby and the object pass through the dangerous areas, and further to provide an operation control method therefor.SOLUTION: An automatic revolving door is constituted of: fixed frames 800 and 801; rotary wings 900 and 901; rotary wing driving devices 100 and 102; a detection device 101 for detecting a rotational position; and a control device 200 that causes the rotary wings 900 and 901 to be rotated at low-speed rotation when rotary wing leading end portions enter dangerous areas (an area AB and an area DE) and causes the rotary wings 900 and 901 to be rotated at acceleration, deceleration and steady speeds when the rotary wing leading end portions pass through from the dangerous areas.

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 beautiful appearance and windproof advantages. According to the provisions of China Construction Industry Standard No. JG / T177-2005 "Automatic Doors", revolving automatic doors refer to two to four doors that rotate around the central axis and are controlled by signals. The door body includes fixed doors and movable leaves. Wherein, the fixed door leaf refers to the circular arc-shaped fixed part of the outer periphery of the revolving door. [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 specified, w...
