[0017] Please refer to Figures 1-5 , the embodiments of the present invention provide the following technical solutions: Based on the unmanned self-service explosion-proof detection system in front of the airport terminal building, it includes an explosion-proof detection platform 1 composed of an image analysis module 10, an identity recognition system 11, a tracking module 12, and a safety judgment module 13. In order to achieve a reasonable division of the on-site area of the terminal building, it further includes a first sliding door module 2 and a second sliding door module 3. A detection area 4 is arranged outside the first sliding door module 2, a waiting area 5 is arranged between the first sliding door module 2 and the second sliding door module 3, and a release area 6 is arranged outside the second sliding door module 3. Among them, in order to achieve convenient detection of explosives, an explosion-proof detection module 7 is arranged in the detection area 4. The explosion-proof detection module 7 includes an X-ray detection unit 14 and an explosive detection unit 15. The X-ray detection unit 14 is used to obtain the X image of the luggage and upload it to the image analysis module 10. The explosive detection unit 15 is used to detect specific explosives for personnel and luggage by using ion mobility spectrometry technology, fluorescence analysis technology, or chemical sensor detection technology, such as the general technical requirements for trace drug and explosive detectors based on ion mobility spectrometry technology in GAT 841-2021, and the general technical requirements for trace explosive detectors based on fluorescence polymer sensing technology in GAT 1323-2016, and upload the explosive detection result to the image analysis module 10.

[0018] As a preferred solution, in order to identify the identity information of the personnel in the detection area, a first vision acquisition module 8 is provided in the detection area 4. The first vision acquisition module 8 is used to collect the face information of the personnel in the detection area 4. The identity recognition system 11 is used to receive the face information, identify the identity information corresponding to the face information, and upload the identity information to the security judgment module 13. The security judgment module 13 is respectively connected to the first translation control module 22 and the second translation control module 23. After receiving the identity information, the security judgment module 13 issues a first opening instruction. The first translation control module 22 receives the first opening instruction and opens the first translation door module 2 for a set duration, facilitating the entry of personnel into the waiting area 5.

[0019] As a preferred solution, in order to achieve real-time tracking of the personnel in the waiting area, the image analysis module 10 includes a graphic outlining unit 16, a comparison and alarm unit 17, and a sample storage unit 18. The graphic outlining unit 16 is used to receive the X image and perform area outlining processing on the image to obtain the to-be-detected outlined image. The comparison and alarm unit 17 is connected to the sample storage unit 18. The sample storage unit 18 is used to obtain the outlined images of several dangerous goods as reference samples. The outlined image is the contour information of the dangerous goods. The graphic outlining unit 16 is connected to the comparison and alarm unit 17. The comparison and alarm unit 17 is used to compare the similarity between the to-be-detected outlined graphic and the reference sample to determine whether the to-be-detected outlined graphic is the dangerous good corresponding to the reference sample. When a dangerous good appears, the comparison and alarm unit 17 sends an alarm message to the security judgment module 13. The comparison and alarm unit 17 also receives the explosive detection result. When an explosive appears, it sends an alarm message to the security judgment module 13. When the security judgment module 13 receives the alarm message, it gives an audible and visual alarm and issues a first opening instruction. The first translation control module 22 receives the first opening instruction and opens the first translation door module 2 for a set duration to allow the personnel who fail the explosion-proof detection to return to the detection area 4.

[0020] As a preferred solution, in order to avoid trailing situations, a second vision acquisition module 9 is provided in the waiting area 5. The second vision acquisition module 9 is used to acquire video images of the waiting area 5 as analysis images. The tracking module 12 includes a trajectory simulation unit 19, a trailing analysis unit 20, and a detention analysis unit 21. The trajectory simulation unit 19 is used to obtain the analysis images. After frame image extraction, it obtains the position of the personnel area in the frame images and obtains the personnel movement trajectory information of the waiting area 5 according to the time series. The trajectory simulation unit 19 is docked with the trailing analysis unit 20. The trailing analysis unit 20 is used to determine whether there is a situation of non-single regions of interest in the position of the personnel area in the frame images at the same moment. If so, it determines that a trailing situation occurs; if not, it determines that no trailing situation occurs. When the safety judgment module 13 does not receive an alarm message and no trailing situation occurs, it issues a second opening instruction. The second translation control module 23 receives the second opening instruction and opens the second translation door module 3 for a set duration to allow the personnel who have passed the explosion-proof detection to enter the release area 6.

[0021] As a preferred solution, in order to avoid detention situations, the tracking module 12 further includes a detention analysis unit 21. The trajectory simulation unit 19 is docked with the detention analysis unit 21. The detention analysis unit 21 is used to set a detention judgment duration, record the opening time information of the first translation door module 2 or the second translation door module 3 as the starting time, and continue to obtain the position information of the personnel area in the waiting area 5. When the position information of the personnel area still appears within the detention judgment duration after the starting time, it is determined that the personnel in the waiting area 5 are in a detention situation, and the detention information is sent to the safety judgment module 13. The safety judgment module 13 issues a prompt to leave quickly to the waiting area according to the detention information.

[0022] Personnel wait in the detection area 4. The explosion-proof detection module 7 performs explosion-proof sampling on the personnel and the luggage. At the same time, the first vision acquisition module 8 acquires the face information of the personnel and transmits it to the identity recognition system 11. After the identity recognition system 11 recognizes the identity information corresponding to the face information, the safety judgment module 13 issues a first opening instruction. The first translation control module 22 opens the first translation door module 2 to allow the personnel to enter the waiting area 5. During the process, the second vision acquisition module 9 acquires video images of the waiting area as analysis images. After the trajectory simulation unit 19 extracts frame images from the analysis images, it obtains the position of the personnel area in the frame images and obtains the personnel movement trajectory information of the waiting area 5 according to the time series. The trailing analysis unit 20 determines whether there is a situation of non-single regions of interest in the position of the personnel area in the frame images at the same moment. If so, it determines that a trailing situation occurs; if not, it determines that no trailing situation occurs.

[0023] While the personnel are waiting in the waiting area 5, the X-ray detection unit 14 acquires the X image of the luggage and uploads it to the graphic outlining unit 16. The graphic outlining unit 16 performs area outlining processing on the image to obtain the to-be-detected outlined image. The sample storage unit 18 acquires the outlined images of several dangerous goods as reference samples, compares the similarity between the to-be-detected outlined graphic and the reference samples, and determines whether the to-be-detected outlined graphic is the dangerous good corresponding to the reference sample. When a dangerous good appears and / or the detection result of the explosive detection unit 15 shows that an explosive appears, the comparison and warning unit 17 sends a warning message to the safety judgment module 13. When the safety judgment module 13 receives the warning message, it gives an audible and visual alarm and issues a first opening instruction. The first translation control module 22 opens the first translation door module 2 to allow the personnel who fail the explosion-proof detection to return to the detection area 4.

[0024] When the safety judgment module 13 does not receive a warning message and no trailing situation occurs, it issues a second opening instruction. The second translation control module 23 opens the second translation door module 3 to allow the personnel who pass the explosion-proof detection to enter the release area 6.
