[0007] However, because infrared is easily disturbed in the outdoor environment, and the telescopic door body is prone to shake during operation, it is difficult to control the emission direction of infrared rays. Therefore, this infrared trackless electric telescopic door guide device has extremely high requirements for the working environment and is practical. sex needs to be improved

Embodiment 1
[0024] Such as figure 1 and figure 2 As shown, in this embodiment, the automatic door is a single door, and the automatic door includes two oppositely arranged door stacks (1a, 1b), a telescopic door body 2, and a machine head that drives the telescopic door body 2 to move 3. Wherein, one end of the telescopic door body 2 is fixedly connected with the door stack 1a, and the door stack 1b is used as the terminal door stack when the automatic door is closed. Moreover, the bottom of the telescopic door body 2 and the bottom of the machine head 3 are both provided with rollers 4 .
[0025] Such as Figure 1 to Figure 3 As shown, in this embodiment, the method for detecting and correcting the deviation of the straight line running of the automatic door includes the following steps:
[0026] Step 1: Install the mark 5 on the top center of the machine head 3, install the camera 6 on the end door stack 1b when the automatic door is closed, and make the mark 5 be in the center of ...
Embodiment 2
[0038] In this embodiment, the same parts as those in the first embodiment are given the same numbers, and the same descriptions are omitted.
[0039] Such as Figure 4 and Figure 5As shown, in this embodiment, the automatic door is a double door, and the automatic door includes two oppositely arranged door stacks (1a, 1b), two telescopic door bodies (11a, 11b), and two machine heads ( 12a, 12b). Among them, the door stack 1a is connected to the fixed end of the telescopic door body 11a, the door stack 1b is connected to the fixed end of the telescopic door body 11b, and the movable end of the telescopic door body 11a is connected to the machine head 12a, while the movable end of the telescopic door body 11b Connect with the head 12b. That is, the telescopic door body 11a and the telescopic door body 11b are respectively driven to move by the machine heads 12a and 12b. In addition, the bottom of each telescopic door body (11a, 11b) and the bottom of each machine head (12a...

Abstract
The invention discloses a deviation detection and correction method for automatic door straight-line running. According to the method, a machine head and a gate stack are provided with a mark and a camera respectively, the camera detects the running state of the machine head in a timed photographing mode, and then, a control device judges whether deviation happens to running of the machine head or not on the basis of pictures; when the control device judges that deviation happens to running of the machine head, the control device sends a correction instruction to a drive device in the machine head, and the drive device drives the machine head to be adjusted in the direction opposite to the deviation direction according to the correction instruction; when the straight-line running state of the machine head is restored, the machine head straightly runs to an end point. The deviation detection and correction method for automatic door straight-line running has the advantages of being simple, practical, accurate in correction, small in error and high in efficiency.
Description
technical field [0001] The invention relates to the field of automatic doors, in particular to a method for detecting and correcting deviations in straight line running of an automatic door. Background technique [0002] Because the retractable automatic door has the advantages of beautiful appearance, high degree of automation, and stable and reliable operation. The retractable automatic doors are widely used in public places such as industrial and mining enterprises, government institutions, entertainment venues, hotels and restaurants. [0003] Early retractable automatic doors usually consist of a retractable door body, a machine head, guide rails, and a controller. For the straight-line running track of the telescopic door body, it is directly limited by the guide rail laid on the ground. For example, the Chinese invention patent (CN 102720427A) discloses a track-type retractable door, which includes a track, a folding door unit, a fixed column and a driving head, and...
