DETAILED DESCRIPTION OF THE EMBODIMENTS

[0016] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0017] See also Figure 1-2 The embodiment of the present invention provides the following technical solution, based on the airport terminal personnel exit anti-return door passage system, including a door frame channel frame 1, the front and rear sides of the top of the door frame channel frame 1 are fixedly installed with abnormal passage alarms 12, and the door frame channel frame 1 is rotatably installed with an A door module 7 and a B door module 8, as shown in the attached Figure 2 As shown, the door frame channel frame 1 includes, from front to back, an entrance detection area 2, a door A safety detection area 3, a return detection area 4, a door B detection area 5 and an exit detection area 6 which are connected in sequence. The A door module 7 is arranged between the entrance detection area 2 and the A door safety detection area 3, and the B door module 8 is arranged between the B door detection area 5 and the exit detection area 6.

[0018] As a preferred solution, in order to realize the automatic door opening operation of the A door module 7, a first TOF laser detection radar 9 is arranged on the side of the A door module 7 close to the entrance detection area 2. The first TOF laser detection radar 9 is used to detect whether there is a person in the entrance detection area 2, and the first TOF laser detection radar 9 is connected to the A door module 7 to control the A door module 7 to open the door when a person is detected in the entrance detection area 2.

[0019] As a preferred solution, in order to realize the automatic door opening operation of the B door module 8, a second TOF laser detection radar 11 is arranged on the side of the B door module 8 close to the B door detection area 5. The second TOF laser detection radar 11 is used to detect whether there are people in the B door detection area 5 and the exit detection area 6. The second TOF laser detection radar 11 is connected to the B door module 8 to control the B door module 8 to open the door when a person is detected in the B door detection area 5, and to control the B door module 8 to close the door when there is no person in the exit detection area 6. It should be noted that when there are people in the exit detection area 6, the B door module 8 will not open the door to avoid harm to the personnel during the door opening process.

[0020] As a preferred solution, in order to achieve automatic and safe closing of the A door module 7, two groups of 3D visual motion detection modules 10 are arranged in the return detection area 4. The 3D visual motion detection module 10 tracks the movement trajectory of the personnel. When the personnel moves from the A door safety detection area 3 to the return detection area 4, the A door module 7 is controlled to close the door to avoid injury to the personnel during the closing process.

[0021] Further explanation: a lighting system is installed in the door frame channel frame 1 to indicate the channel status, so as to guide pedestrians to pass through the channel quickly.

[0022] As a preferred solution, to ensure the efficient and unobstructed use of the passage, the 3D vision motion detection module 10 is used to detect whether there are people staying in the A-door safety detection area 3 and the exit detection area 6, and when there is a situation of people staying, it controls the passage anomaly alarm 12 to issue an anomaly warning, so as to prompt people to quickly leave the current area to ensure the safe and efficient use of the passage.

[0023] As a preferred solution, the 3D vision motion detection module 10 is docked with the A-door module 7 and the B-door module 8. The 3D vision motion detection module 10 is used to detect for staying objects in the A-door safety detection area 3, the turning-back detection area 4, and the B-door detection area 5, and when staying is detected, it controls the A-door module 7 and the B-door module 8 to remain closed. At this time, the passage is in a state of prohibiting passage.

[0024] As a preferred solution, the 3D vision motion detection module 10 is also used to detect the movement trajectory of people in the turning-back detection area 4. When it is determined that the movement trajectory of people shows a turning-back situation, it controls the A-door module 7 to close and controls the passage anomaly alarm 12 to issue an anomaly warning.

[0025] The above-mentioned first TOF lidar 9, second TOF lidar 11, and 3D vision motion detection module 10 are all arranged on the top inside the door frame passage frame 1.

[0026] Further explanation, regarding the opening and closing of the A-door module 7 and the B-door module 8, the combined mode can be switched according to requirements. The combined mode includes but is not limited to the automatic mode, the interlock mode, the flow mode, the cleaning / maintenance mode, and the emergency mode. Specifically: Flow mode: The A-door module 7 and the B-door module 8 are opened simultaneously. This mode can be used during large passenger flows, but the security level of the passage will be reduced in this mode; Interlock mode: Only the A-door module 7 or the B-door module 8 is allowed to open at the same time, with a high security level; Automatic mode: It can automatically switch between the flow mode and the interlock mode according to the passenger flow; Cleaning mode: It is used for daily cleaning inside the passage. By setting a time threshold, an alarm is issued after reaching the time threshold; Maintenance mode: It is used for equipment maintenance personnel to maintain or repair the equipment. By setting a time threshold, an alarm is issued after reaching the time threshold.

[0027] During use, the person to be tested waits in the entrance detection area 2. After the first TOF laser detection radar 9 detects the movement trajectory of the person, the revolving door of the A-door module 7 opens, and the person to be tested enters the A-door security detection area 3. At this time, the 3D vision motion detection module 10 detects the movement trajectory of the person to be tested in the passage. When the person to be tested walks into the return detection area 4, the revolving door of the A-door module 7 closes. If the person to be tested has been in the A-door security detection area 3, the revolving door of the A-door module 7 will not close to prevent pinching. At this time, the alarm function of the passage anomaly alarm 12 will be triggered to remind the person to be tested to pass. The person to be tested walks to the B-door detection area 5, and the revolving door of the B-door module 8 opens. The person to be tested walks to the exit detection area 6. At this time, the second TOF laser detection radar 11 detects the movement trajectory of the person. When the person to be tested walks out of the exit detection area 6, the revolving door of the B-door module 8 closes. If the person to be tested has been in the exit detection area 6, the revolving door of the B-door module 8 will not close to prevent pinching. At this time, the alarm function of the passage anomaly alarm 12 will be triggered to remind the person to be tested to pass. Because the security is greater than the personal safety in the normal passage mode, the revolving doors of the A-door module 7 and the B-door module 8 will not open simultaneously to ensure the security level.

[0028] In summary, the present invention has the functions of pedestrian position tracking and pedestrian return detection. After the pedestrian enters the anti-return door detection area, the anti-return door can identify the position of the person in real time until the pedestrian leaves the anti-return door. And after the pedestrian enters the passage, the anti-return door detects the movement trajectory of the pedestrian. If the pedestrian has an act of approaching the entrance, the anti-return door will immediately close the entrance and issue an alarm.
