Description

Technical Field

[0001] This application relates to the technical field of X-ray detection and control equipment, and in particular to an X-ray detection and control method, system and equipment based on an AI large model. Background Technology

[0002] In scenarios such as public safety, logistics security inspection, and security for major events, explosive detection is a key link in preventing terrorist attacks and protecting the lives and property of people. Currently, X-ray detectors have become the mainstream equipment for explosive detection because they can penetrate carriers such as packages and luggage and intuitively present information such as the shape, density, and material of the internal items. They are widely used in various security inspection scenarios. The core principle is to form a grayscale image by using the attenuation difference when X-rays penetrate an object. Staff can then determine whether there are explosives based on the image features. However, the detection process of traditional X-ray detectors relies entirely on manual operation and experience. With the increasing demand for security checks and the increasingly concealed forms of explosives, their low efficiency and high false alarm rate have become more and more prominent. Traditional equipment requires security personnel to manually complete operations such as placing the items to be inspected, setting parameters, starting the detection, and retrieving images. The X-ray image characteristics of explosives are similar to those of some everyday items. Traditional detection relies entirely on the experience and judgment of security personnel, which is prone to false alarms and missed detections.

[0003] Regarding the aforementioned technologies, the inventors discovered that the entire X-ray inspection process requires manual intervention. From equipment operation and image observation to result judgment, it all depends on the individual actions and reaction speed of security personnel. This is severely inefficient in high-traffic security inspection scenarios, the equipment operation is cumbersome, and the inspection of a single batch takes a long time. Summary of the Invention

[0004] To overcome the limitations of existing X-ray inspection equipment, which requires manual intervention throughout the entire inspection process, from equipment operation and image observation to result judgment, all of which rely on the individual actions and reaction speed of security personnel, resulting in severe inefficiency in high-traffic security inspection scenarios, cumbersome equipment operation, and long processing time for each batch of inspections, this application provides an X-ray inspection control method, system, and equipment based on an AI large model.

[0005] The X-ray detection control method, system, and equipment based on an AI large model provided in this application adopt the following technical solution: An X-ray inspection device based on an AI large model includes a support, a lifting component, a bending component, a displacement component, and an X-ray inspection device. The lifting component is vertically arranged above the support, and its bottom end is rotatably connected to the top surface of the support. The bending component is slidably arranged vertically inside the lifting component, and a displacement component is arranged on the side of the bending component away from the lifting component. One end of the displacement component is rotatably connected to the end face of the bending component away from the lifting component, and an X-ray inspection device is slidably assembled below the displacement component. The X-ray inspection device is used to irradiate and inspect objects.

[0006] By adopting the above technical solution, the support component, as the supporting structure of the entire equipment, ensures the stability of other components. The lifting component can move up and down on the support component to adjust the height of the X-ray inspection device to meet the inspection needs of items of different heights. The bending component can slide along the inside of the lifting component and adjust its angle by rotation, allowing X-rays to irradiate the inspected item from different directions, thereby improving the comprehensiveness and accuracy of the inspection. The displacement component is used to further fine-tune the angle of the bending component, increasing operational flexibility. The X-ray inspection device is responsible for emitting X-rays and receiving the reflected signals. By analyzing these signals, it determines the internal structure of the item and whether there are any abnormalities, achieving efficient and accurate non-destructive testing. First, the height of the equipment is adjusted by the lifting component, then the X-ray irradiation angle is adjusted by the bending and displacement components, then the X-ray inspection device emits X-rays and scans the item for inspection, and finally the condition of the item is determined by analyzing the inspection data.

[0007] Optionally, the support includes a lower support frame, with rollers fixed on the bottom surface of the lower support frame and a battery inserted inside the lower support frame. An upper support frame is vertically fixed on the top surface of the lower support frame, and a push frame is fixed on one side of the upper support frame. An angle adjustment motor is vertically fixed on one side of the top surface of the lower support frame, and an angle adjustment main gear is horizontally fixed at the output end of the angle adjustment motor.

[0008] By adopting the above technical solution, the lower support frame in the support component mainly serves to support the entire device, and the rollers fixed on its bottom surface enable the device to be moved easily. A battery inserted inside the lower support frame serves as the power source, providing the necessary electrical energy for the entire device. The upper support frame ensures its stability by being vertically fixed to the top surface of the lower support frame, and a pusher fixed on one side facilitates manual movement of the device. The angle adjustment motor is installed on one side of the top surface of the lower support frame, and its output end is horizontally fixed to the angle adjustment main gear to adjust the angle of the device, thus meeting the needs of different usage scenarios. The overall working principle is as follows: operating the angle adjustment motor drives the angle adjustment main gear to rotate, thereby realizing the rotation of the upper support frame and its components. Simultaneously, the rollers and pusher ensure the ease of movement and manual operation of the device, respectively. Combined with the stable power supply provided by the battery, the entire support component can flexibly adapt to various usage environments.

[0009] Optionally, the lifting component includes a lifting slide frame, which is vertically positioned above the upper support frame. A rotating column is vertically fixed on the bottom surface of the lifting slide frame. The rotating column of the lifting slide frame is rotatably connected to the top surface of the upper support frame. An angle-adjusting driven gear is horizontally fixed to the outside of the rotating column, and the angle-adjusting driven gear meshes with the angle-adjusting main gear. A lifting screw is vertically rotatably connected inside the lifting slide frame, and a lifting motor is fixed on the top surface of the lifting slide frame. The output end of the lifting motor is fixed to the end of the lifting screw.

[0010] By adopting the above technical solution, the overall design of the lifting component aims to achieve rapid and precise lifting functions, as well as angle adjustment. The lifting slide frame, as a key component, can slide vertically, is installed above the upper support frame, and is rotatably connected to the top surface of the upper support frame via a rotating column at its bottom, thus forming an integrated lifting and angle adjustment function. An angle adjustment driven gear fixed on the rotating column meshes with the main gear to synchronously control the vertical position and angle adjustment of the lifting slide frame. The lifting screw inside the lifting slide frame works in conjunction with an external lifting motor; the motor drives the screw to rotate, thereby moving the lifting slide frame up and down. This not only allows for precise control of the lifting position of the slide frame but also enables angle adjustment through the meshing of the main and driven gears, providing the entire structure with flexible and diverse spatial adjustment capabilities. It achieves the dual functions of lifting and angle adjustment, suitable for spatial layouts requiring multi-directional adjustment.

[0011] Optionally, the bending component includes a screw hole slide plate, which is vertically slidably assembled on the lifting slide frame, and the screw hole slide plate is threadedly connected to the lifting screw. Rotating frames are fixed on both sides of the end face of the screw hole slide plate near the displacement component, and a bending motor is horizontally fixed on the screw hole slide plate, and a bending adjustment main gear is fixed at the output end of the bending motor.

[0012] By adopting the above technical solution, the screw-hole slide plate, as a sliding component, can slide vertically within the lifting slide frame, thereby achieving the lifting function of the bent part. The screw-hole slide plate and the lifting screw are connected by a threaded connection, allowing the screw-hole slide plate to move up and down along the lifting screw when it rotates. A rotating frame is fixed to both sides of one end face of the screw-hole slide plate, providing fixed support points and ensuring the bent part maintains a stable structure during lifting. The bending motor is mounted on the screw-hole slide plate and connected to the bending adjustment main gear through its output end. By driving the main gear to rotate, the angle of the bent part can be adjusted, thus changing its working position or angle. When the lifting screw rotates, the screw-hole slide plate moves the bent part up and down, while the bending motor drives the bending adjustment main gear, adjusting the angle of the bent part through gear transmission, thereby achieving dual adjustment functions for both height and angle of the bent part.

[0013] Optionally, the displacement component includes a displacement frame, with a bending rod fixed at one end of the displacement frame near the screw hole slide plate, and the bending rod is rotatably connected to the rotating frame. A bending adjustment driven gear is fixed in the middle of the bending rod, and the bending adjustment driven gear meshes with the bending adjustment main gear.

[0014] By adopting the above technical solution, the displacement frame in the displacement component is responsible for supporting the entire displacement mechanism. Through a sliding engagement between a bent rotating rod fixed at one end and the rotating frame, the displacement frame can move flexibly. A bent adjusting driven gear fixed in the middle of the bent rotating rod meshes with a bent adjusting main gear in the rotating frame. Through the meshing of the gears and the rotation of the rotating frame, precise displacement of the displacement frame can be achieved. Specifically, when the bent adjusting main gear rotates, power is transmitted through the meshing of the bent adjusting driven gear, causing the bent rotating rod to rotate relative to the rotating frame, thereby driving the displacement frame to move in a specified direction, thus achieving precise positioning and adjustment. Through the rotation of the bent adjusting main gear, and via the meshing and rotation of the bent adjusting driven gear and the bent rotating rod, precise displacement of the displacement frame along a predetermined path is ultimately achieved.

[0015] Optionally, the rotating frames on both sides of the screw hole slide plate are horizontally perforated with insertion holes, and positioning rods are horizontally slidably inserted into the insertion holes of the rotating frames. Return springs are horizontally sleeved on the outside of the positioning rods, and the two ends of the return springs are respectively fixed to the outer end face of the rotating frames and the end of the positioning rods. A double-headed electric cylinder is horizontally arranged above the screw hole slide plate, and the output rods at both ends of the double-headed electric cylinder are fixed to the positioning rods on both sides of the rotating frames of the screw hole slide plate. Hole plates are fixed on both sides of the bent rotating rods, and the hole plates are positioned and inserted into the positioning rods.

[0016] By adopting the above technical solution, the screw-hole slide plate serves as a load-bearing and fixing element, while the rotating frames on both sides are fixed and adjusted in position through insertion holes and positioning rods. The positioning rods, under the action of return springs, can undergo slight displacement and reset, ensuring the stability and flexibility of the device. The double-headed electric cylinder pushes the positioning rods on both sides of the screw-hole slide plate through its output rods at both ends, moving them horizontally to achieve overall positioning and adjustment of the device. The insertion and engagement of the perforated plate and the positioning rods further enhances the positioning accuracy, ensuring the fixation and rotation of both sides of the bent rotating rod. Through the electric cylinder driving the screw-hole slide plate and the rotating frames and positioning rods on both sides in coordination, precise and flexible positioning and adjustment of the bent rotating rod are achieved, improving the stability and working accuracy of the equipment.

[0017] Optionally, a displacement screw is horizontally rotatably connected inside the displacement frame, and a displacement motor is fixed at the end of the displacement frame. The output end of the displacement motor is fixed at the end of the displacement screw. A screw hole hanger is fixed on the top surface of the X-ray detection device, and the screw hole hanger on the X-ray detection device is slidably assembled inside the displacement frame. The screw hole hanger on the X-ray detection device is threadedly connected to the displacement screw.

[0018] By employing the above technical solution, the displacement frame provides a horizontally rotating space, while the displacement screw rotates horizontally within this frame. The displacement screw is connected to the screw-hole hanger on the X-ray inspection device via a threaded connection, allowing the X-ray inspection device to move linearly within the displacement frame. A displacement motor is mounted at the end of the displacement frame and connected to the displacement screw. By controlling the rotation of the displacement motor, the displacement screw can be precisely driven to rotate, thereby causing the X-ray inspection device to move horizontally. In this way, the displacement motor, through the cooperation of the displacement screw and the screw-hole hanger, achieves automated displacement control of the X-ray inspection device, enabling the device to accurately position and scan at different locations requiring inspection.

[0019] Optionally, a support frame is fixed to the top of the lifting component on the side away from the bending component, and a controller is fixed inside the support frame. The controller integrates a signal receiver, a signal transmitter, and a display screen.

[0020] By adopting the above technical solution, a support frame is fixed to the top of the lifting component on the side away from the bending component. This support frame supports and securely mounts the controller, ensuring its stability and positional accuracy within the mechanical structure. The controller integrates a signal receiver for receiving external signals, such as remote control or radio signals. A signal transmitter sends control signals to other devices or systems, and a display screen shows the current operating status, fault information, or operation prompts. The entire system works by receiving and processing external signals, and then sending control signals to the lifting and bending components. This causes the lifting component to move the support frame, thus adjusting the angle and position of the detected object.

[0021] An AI-based X-ray detection and control system includes an AI-based X-ray detection device, an AI-based X-ray detection server, and a cloud database. The X-ray detection device is responsible for acquiring X-ray image data and transmitting it to the AI-based X-ray detection server. The AI-based X-ray detection server runs a pre-trained model, receives and processes data from handheld devices, and performs image recognition and analysis tasks. The cloud database is used to store detection results and model training data, and supports iterative model updates.

[0022] An X-ray detection control method based on an AI large-scale model, which uses an AI large-scale model-based X-ray detection device, includes the following steps: S1. A handheld X-ray inspection device is used to acquire X-ray image data of the object under test; S2. Input the collected X-ray image data into a pre-trained AI model, which is capable of feature learning and classification based on a large number of explosive image samples. The S3 AI big model performs real-time analysis of input image data to identify potential explosives and outputs detection results and confidence scores. S4. Based on the detection results, the handheld device automatically adjusts the intensity and exposure time of the X-ray source to optimize the subsequent image quality; S5. The test results are displayed on the device screen to the operator and simultaneously sent to the cloud database for recording and analysis. In summary, this application includes at least one of the following beneficial technical effects: 1. Through automatic angle adjustment, intelligent height adaptation, and mechanical positioning and locking design, the entire detection process is automated, significantly reducing operation time. Automatic angle adjustment covers all detection scenarios, eliminating the need for manual item flipping. The horizontal deflection adjustment controller activates the angle adjustment motor, which, through the meshing of the main and driven gears, drives the X-ray detection device to achieve horizontal deflection, allowing for quick switching between the detection perspective of the front and side of the item, avoiding manual handling and flipping. Vertical bending adjustment utilizes a dual-headed electric cylinder to quickly unlock the positioning rod, and the bending motor drives the detection device to bend vertically, adapting to the detection of hidden areas at the top and bottom of the item, eliminating the need for manual adjustment of the equipment's placement. The synergistic effect of multi-dimensional adjustments shortens the switching time of the detection perspective for a single item, improving coverage efficiency. Automatic height adjustment uses a lifting motor to drive the lifting screw, which in turn drives the X-ray detection device, achieving adaptive adjustment without the need for manual adjustment of the height by turning the knob. Automatic angle locking, once the detection angle is determined, automatically retracts the dual-headed electric cylinder, and the positioning rod inserts into the orifice plate for mechanical locking, eliminating the need for manual fixation. This technology only requires placing the item and starting the detection, reducing operation steps and improving detection efficiency. 2. By using AI analysis of X-ray signals and comparison with cloud databases, the detection results can be automatically determined, completely eliminating the reliance on human experience. AI real-time analysis and cloud comparison improve the efficiency of image interpretation. The detection electrical signals of the X-ray detection device are transmitted to the controller in real time. After preprocessing, they are sent to the AI ​​large model server through the signal transmitter. The server retrieves the cloud database and completes feature comparison and result determination through deep learning algorithms. The whole process is time-saving and improves detection accuracy.

The signal transmitter 272 sends control signals to other devices or systems, and the display screen 273 displays the current operating status, fault information, or operation prompts. The entire system works by receiving and processing external signals, and the controller 27 sends control signals to the lifting component 2 and the bending component 3, causing the lifting component 2 to move the support frame 26, thus adjusting the detection angle and position of the object.

[0033] The implementation principle of an X-ray inspection device based on an AI large model in this application embodiment is as follows: First, during the inspection, the pusher 17 in the hand support 1 is used to push the roller 13 on the bottom surface of the lower support frame 11 to move to the position of the item to be inspected. Then, the X-ray inspection device 5 is started by using the controller 27 to inspect and irradiate the upper side of the item to be inspected. Meanwhile, during the inspection, in order to better and more comprehensively irradiate the item to be inspected, when it is necessary to adjust the irradiation direction of the X-ray inspection device 5, the controller 27 controls the angle adjustment motor 15 on the top surface of the upper support frame 12 to start. The angle adjustment main gear 16 meshes with the angle adjustment driven gear 23 on the rotating column 22 on the bottom surface of the lifting slide frame 21 in the lifting component 2, causing the lifting component 2 to deflect left and right on the top surface of the upper support frame 12, switching the inspection position of the item to be inspected. The controller 27 controls the double-headed electric cylinder 36 to extend, pushing the positioning rods 35 on the rotating frames 32 on both sides of the screw hole slide plate 31 to slide outward, so that the positioning rods 35 are pulled out of the hole plate 46 on the bent rotating rod 44. The controller 27 also controls the bending motor 33 on the screw hole slide plate 31 to start, driving the bending adjustment main gear 34 to mesh with the bending adjustment driven gear on the bending rotating rod 44 at the end of the displacement component 4. The wheel 45 engages, causing the bending rotating rod 44 to deflect up and down on the screw hole slide plate 31, switching the bending angle of the X-ray detection device 5 on the item to be inspected, thereby comprehensively adjusting the inspection angle of the item to be inspected. During inspection, in order to maintain the bending angle of the displacement component 4 on the item to be inspected, the controller 27 controls the double-headed electric cylinder 36 to retract, pushing the positioning rods 35 on the rotating frames 32 on both sides of the screw hole slide plate 31 to slide inward, so that the positioning rods 35 are inserted into the hole plate 46 on the bending rotating rod 44, keeping the bending angle of the displacement component 4 on the item to be inspected fixed. Then, when inspecting the item, the controller 27 controls the lifting motor 25 on the top surface of the lifting slide frame 21, and the lifting motor 25 drives the lifting screw 24 to rotate, which drives the screw hole slide plate 31 to move vertically downward in the lifting slide frame 21, adjusting the inspection height of the X-ray detection device 5. Finally, the electrical signal detected by the X-ray detection device 5 is input to the controller 27. After being processed by the controller 27, it is transmitted to the signal transmitter 272. The signal transmitter 272 then transmits the signal to the AI ​​large model server. The AI ​​large model server retrieves the pre-stored information from the cloud database, compares and judges it. The judged signal is received by the signal receiver 271 and transmitted to the controller 27 for processing. The judged information data is then displayed on the display screen 273.
