Description

Technical Field

[0001] The present invention relates to the technical field of CT security inspection systems for luggage and articles, and particularly to a CT security inspection system for luggage and articles and its detector. Background Art

[0002] A CT security inspection system for luggage and articles is a security inspection device that uses X-ray tomography technology (CT technology) to perform imaging detection on the internal structure of luggage and articles. The working principle of this device is that an X-ray source emits a fan-shaped or conical X-ray beam, which passes through the luggage and articles to be detected. Since different substances have different absorption capabilities for X-rays, the detector receives the X-ray signal after passing through the articles and converts it into an electrical signal. These electrical signals are processed and reconstructed by a computer, and finally a tomographic image of the luggage and articles is generated. By analyzing the multi-layer tomographic images, security inspectors can clearly observe the detailed situation inside the luggage.

[0003] In the operation of existing devices, images often overlap during detection because people stack luggage together. Secondly, when detecting, people often place objects of different weights together, which may cause deviation during detection. Secondly, on rainy days, since the surfaces of people's backpacks or suitcases are stained with some water stains, these water stains will adhere to the conveyor belt during CT security inspection. Over time, this will cause irreversible damage to the electronic components inside the device. Therefore, we propose a CT security inspection system for luggage and articles and its detector.

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0019] As introduced in the background art, there are deficiencies in the prior art. To solve the above technical problems, the present application proposes a CT security inspection system for luggage and articles and its detector.

[0020] In a typical implementation mode of the present application, as Figures 1-12 shown, a CT security inspection system for luggage and articles and its detector include an equipment main body 1. A number of groups of support legs 12 are fixedly arranged at equal intervals at the bottom of the equipment main body 1. The bottom inner wall of the equipment main body 1 is fixedly connected with a U-shaped fixing plate 11. The left side inner wall of the U-shaped fixing plate 11 is rotatably connected with a first conveying roller 17. The right side inner wall of the U-shaped fixing plate 11 is rotatably connected with a second conveying roller 19. The first conveying roller 17 and the second conveying roller 19 are connected by a conveyor belt 20. The front outer wall of the U-shaped fixing plate 11 is fixedly connected with a first motor 18. The output end of the first motor 18 is fixedly connected with the first conveying roller 17; It should be noted that there are two sets of scanning device bodies 5 designed inside the device body 1. The devices implemented by the scanning device body 5 refer to the X-ray source and the detector. The working principle is that the X-ray penetrates the luggage, and the detector array rotates synchronously around the luggage to emit X-rays from different angles and collect projection data, and a three-dimensional image is generated using computed tomography technology. No matter what the luggage is like, the internal items can be detected. The detailed working process will not be elaborated here. Then, when the luggage passes through the detection component 3 from the left side of the device body 1, it will be distinguished according to the weight of the luggage at the detection component 3. This design is to prevent the luggage from tipping and stacking during the movement due to the weight problem, thus affecting the detection result. Secondly, when the luggage is placed on the left conveyor belt 20 of the device body 1, the first motor 18 is immediately started. The first motor 18 drives the first conveyor roller 17 to rotate. The first conveyor roller 17 is connected to the second conveyor roller 19 through the conveyor belt 20. This design can make the luggage move uniformly on the surface of the conveyor belt 20. It should be mentioned here that the left side of the device body 1 is the entrance and the right side is the exit.

[0021] As a preferred implementation manner in this embodiment, in the above, the detection component 3 includes a weighing platform 6 fixed to the left side of the device body 1. A return frame 13 is fixedly connected to the left side of the weighing platform 6. A conveying component is installed on the inner wall of the return frame 13. A second channel 10 is fixedly connected to the right side of the weighing platform 6. A first channel 9 is fixedly connected to the right side of the weighing platform 6. The first channel 9 and the second channel 10 are symmetrically arranged. Two groups of first telescopic rods 8 are symmetrically and fixedly connected to the front and rear sides of the inner wall of the device body 1 at the position of the weighing platform 6. The output ends of the two groups of first telescopic rods 8 are both fixedly connected with push plates 7. The conveying component includes a second roller 15 rotatably connected to the left side of the inner wall of the return frame 13. A first roller 14 is rotatably connected to the right side of the inner wall of the return frame 13. A third roller 16 is rotatably connected between the second roller 15 and the first roller 14. A second motor 39 is fixedly connected to the front outer wall of the return frame 13. A second synchronous wheel 38 is rotatably connected to the front outer wall of the return frame 13. A first synchronous wheel 36 is rotatably connected to the front outer wall of the return frame 13. The first synchronous wheel 36 and the second synchronous wheel 38 are connected by a synchronous belt 37. The output end of the second motor 39 is fixedly connected with the second synchronous wheel 38. The second synchronous wheel 38 is coaxially fixed with the first roller 14. The first synchronous wheel 36 is coaxially fixed with the second roller 15; Specifically, when a person places luggage on the left side of the device main body 1, the luggage will slowly move forward as the conveyor belt 20 moves. When it reaches the return rack 13, the second motor 39 will be started synchronously at this time, and the luggage will gradually climb to the surface of the return rack 13 and finally reach the top of the weighing platform 6. In this process, it should be noted that the surfaces of the second roller 15 and the first roller 14 are both rough designs. The purpose of this design is to increase the friction with the luggage, facilitating the luggage to climb to the surface of the return rack 13 and reach the top of the weighing platform 6. Secondly, a return rack 13 is designed between the second roller 15 and the first roller 14. The design of the return rack 13 is used to assist the displacement of the luggage. When the luggage reaches the top of the weighing platform 6, the weighing platform 6 will weigh the luggage at this time. It should be noted here that the initial data of the weighing platform 6 depends on the design of the staff. When the weight of the luggage is lower than the initial data, it is determined as lightweight luggage. At this time, the first telescopic rod 8 far from the first channel 9 will be started, and the luggage will be pushed to the first channel 9 by the push plate 7 and slide down. During the sliding process, the scanning device main body 5 will detect it. Then, when the weight of the luggage exceeds the initial data, it is determined as heavy luggage at this time. At the same time, the first telescopic rod 8 far from the second channel 10 will be started, and the luggage will be pushed to the second channel 10 by the push plate 7 and slide down. Similarly, during the sliding process, it will be detected. It should be mentioned that no matter whether the luggage falls from the first channel 9 or the second channel 10, it will ultimately be transported to the exit by the conveyor belt 20. At this time, the staff can observe whether there are prohibited items inside the luggage through the display. If there are prohibited items, the corresponding luggage will be taken down and inspected separately. If not, the staff will take the luggage away.

[0022] Furthermore, in the above solution, when it rains, water stains will adhere to the surface of the luggage. When these luggage with water stains are detected by the device main body 1, the sensor 32 inside the device main body 1 will be started. When the humidity inside the device main body 1 exceeds the initial value of the sensor 32, the dehumidification component 2 will be started at this time and process the inside of the device main body 1. This design is to prevent the water stains on the surface of the luggage from affecting the electronic components inside the device main body 1.

[0023] Among the above, the dehumidification component 2 is used to dehumidify the interior of the device main body 1 to prevent moisture from affecting the internal electronic components of the device main body 1. The dehumidification component 2 includes a second telescopic rod 21 fixed to the top of the inner wall of the device main body 1. The output end of the second telescopic rod 21 is fixedly connected to a U-shaped frame 22. On both sides of the inner wall of the U-shaped frame 22, two groups of support panels 31 are symmetrically installed. On the opposite sides of the two groups of support panels 31, a number of fixing blocks 28 are symmetrically and fixedly connected. A cleaning roller 29 is rotatably connected between every two opposite fixing blocks 28. On the top of the inner wall of the U-shaped frame 22, a number of first air outlet blocks 27 are fixedly arranged at equal intervals. On the left and right sides of the inner wall of the U-shaped frame 22 at the position of the fixing blocks 28, a number of sensors 32 are symmetrically and fixedly connected. On the right side of the U-shaped frame 22, two groups of panels 26 are symmetrically rotatably connected. On the opposite sides of the two groups of panels 26, a number of second air outlet blocks 34 are installed. On the opposite sides of the inner wall of the U-shaped frame 22, a number of springs 30 are fixedly connected at equal intervals and symmetrically. One end of each of the number of springs 30 away from the U-shaped frame 22 is fixedly connected to the support panel 31. On the top of the U-shaped frame 22, on both sides of the second telescopic rod 21, two groups of first air plates 24 are symmetrically and fixedly connected. The two groups of first air plates 24 communicate with the first air outlet blocks 27. On the top of the two groups of first air plates 24, first connecting pipes 23 are fixedly connected. Near the panels 26 on the top of the two groups of first air plates 24, second connecting pipes 25 are fixedly connected. On the opposite sides of the panels 26, four groups of ultraviolet irradiation lamps 33 are symmetrically and fixedly connected. On the bottom of the opposite sides of the panels 26, second air plates 35 are fixedly connected. A number of second air outlet blocks 34 are all arranged at the bottom of the second air plates 35. One end of the two groups of second connecting pipes 25 away from the first air plates 24 corresponds to and is fixedly connected to the top of the second air plates 35. On the right side of the device main body 1, near the panels 26, a protective housing 40 is fixedly connected. The heating component includes a rectangular box 43 fixed to the right side of the top of the device main body 1. Inside the rectangular box 43, two groups of fans 44 are fixedly connected. On the top of the rectangular box 43, a cover plate 45 is fixedly connected. On the rear outer wall of the rectangular box 43, a heating box 46 is fixedly connected. Inside the rectangular box 43, a heating rod 42 is fixedly connected. The output end of the heating box 46 is connected to the heating rod 42. On the bottom of the rectangular box 43, two groups of air vents 41 are symmetrically opened. The bottoms of the two groups of air vents 41 are connected to the tops of the first connecting pipes 23 in a one-to-one correspondence; In this embodiment, when the sensor 32 detects that the humidity inside the device main body 1 exceeds the initial value, the second telescopic rod 21 will be activated and drive the U-shaped frame 22 to move downward. It should be noted that the moving distance of the second telescopic rod 21 is adaptively adjusted according to the height of the luggage. When adjusted to the appropriate height, the second telescopic rod 21 will stop. At this time, the luggage pieces will pass through the cleaning roller 29 in sequence. It should be noted that the cleaning roller 29 is rotatably connected to the opposite sides of the fixed block 28, and the fixed block 28 is fixed on the support panel 31. The support panel 31 is fixed to the U-shaped frame 22 by several groups of springs 30. This design enables the cleaning roller 29 to effectively clean the water stains on the surface of the luggage when the luggage passes by. There are several groups of water-absorbing brushes on the surface of the cleaning roller 29. Then, after the luggage is processed by the cleaning roller 29, hot air will be blown to the surface of the luggage at the first air outlet block 27 at this time. This design can completely dry the water stains on the surface of the luggage. It should be mentioned that the tops of several groups of the first air outlet blocks 27 are connected to the first air plate 24, and the top of the first air plate 24 is connected to the air outlet 41 through two groups of first connecting pipes 23 respectively. A rectangular box 43 is fixed on the upper right side of the device main body 1, and a heating box 46 is fixed on the front outer wall of the rectangular box 43. By heating the heating rod 42, the fan 44 discharges the hot air from the first air outlet block 27 and dries the luggage. At the same time, there are also two second connecting pipes 25 on the upper right side of the first air plate 24. The other ends of the second connecting pipes 25 are connected to the second air plate 35. When the luggage continues to move, it will pass through two groups of panels 26, and the two groups of panels 26 are rotatably designed on the outer wall of the right side of the U-shaped frame 22 by torsion springs. When the luggage passes through the panels 26, the two groups of panels 26 will be pushed open. During this process, four groups of ultraviolet irradiation lamps 33 will irradiate the luggage to help sterilize it. Finally, the luggage will come out from the right side of the device main body 1 and be taken away by personnel. Finally, it should be mentioned that there are two groups of second air plates 35 designed at the bottom of the opposite sides of the panels 26, and there are several groups of second air outlet blocks 34 designed at the bottom of the second air plates 35. The several groups of second air outlet blocks 34 will follow the movement of the panels 26 to dry the surface of the conveyor belt 20 to ensure that the water stains will not damage the electronic components inside the device main body 1.

[0024] Working principle of the present invention: When a person places luggage on the left side of the device main body 1, the luggage will slowly move forward as the conveyor belt 20 moves. When it reaches the return rack 13, the second motor 39 will be started synchronously at this time, and the luggage will gradually climb onto the surface of the return rack 13 and finally reach the top of the weighing platform 6. In this process, it should be noted that the surfaces of the second roller 15 and the first roller 14 are both rough designs. The purpose of this design is to increase the friction with the luggage, so as to facilitate the luggage to climb onto the surface of the return rack 13 and reach the top of the weighing platform 6. Secondly, a return rack 13 is designed between the second roller 15 and the first roller 14. The design of the return rack 13 is used to assist the displacement of the luggage. When the luggage reaches the top of the weighing platform 6, the weighing platform 6 will weigh the luggage at this time. It should be noted here that the initial data of the weighing platform 6 depends on the design of the staff. When the weight of the luggage is lower than the initial data, it is determined as lightweight luggage. At this time, the first telescopic rod 8 far away from the first channel 9 will be started, and the luggage will be pushed to the first channel 9 to slide down through the push plate 7. During the sliding process, the scanning device main body 5 will detect it. Then, when the weight of the luggage exceeds the initial data, it is determined as heavy luggage at this time. At the same time, the first telescopic rod 8 far away from the second channel 10 will be started, and the luggage will be pushed to the second channel 10 to slide down through the push plate 7. Similarly, during the sliding process, it will be detected. It should be mentioned that no matter whether the luggage falls from the first channel 9 or the second channel 10, it will finally be transported to the exit by the conveyor belt 20. At this time, the staff can observe whether there are prohibited items inside the luggage through the display. If there are prohibited items, the corresponding luggage will be taken down and inspected separately. If not, the staff will take the luggage away.

[0025] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
