[0047] As illustrated in Fig. 1, a vehicle inspection system according to an embodiment of the present invention includes: an inspection pass 101, a vehicle hauling system 100 and a radiographic inspection system 151.
[0048] As shown in Fig. 2, the vehicle drag system 100 includes a first drag means 111 and a second drag means 112, which are sequentially arranged along a vehicle drag direction E, wherein, in the vehicle drag direction E, means 111 are arranged upstream of the second drag means 112, and a separation section 113 is arranged between the first drag means 111 and the second drag means 112, to separate the first means drag 111 of the second drag medium 112 at a predefined distance in the drag direction of vehicle E. The first drag medium 111 and the second drag medium 112 are arranged in inspection passage 101. The paths of at least part of the beams of the radiographic inspection system 151 pass the separation section 113 between the first drag means 111 and the second drag means 112.
[0049] In some embodiments of the present invention as illustrated in Figs. 1 and 2, the radiographic inspection system 151 includes a radiation source 152 arranged on a part of the upper and lower side of the separation section 113 between the first drag means 111 and the second drag means 112, and a detector 153 at least partially arranged on the other part of the upper side and the bottom side of the separation section 113 between the first drag means 111 and the second drag means 112 is used to receive beams emitted by the radiation source 152 and penetrate through the inspected vehicle. The radiation source 152 can be an X radiation source or other suitable radiation sources.
[0050] For example, as illustrated in Fig. 1 and Fig. 2, the radiation protection walls 70 are arranged on both sides of the inspection passage 101, a scanning medium structure 80 is arranged within the range of inspection passage 101, radiation source 152 is arranged at the top of the scanning medium structure 80 to scan the vehicle that passes inspection period 101 and detector 153 is disposed under the ground corresponding to radiation source 152 .
[0051] In some embodiments of the present invention as shown in Fig. 11, the radiographic inspection system 151 may include a slip ring 154, a radiation source 152 installed on the slip ring 154 and a detector 153 installed on the slip ring 154, in which detector 153 is used to receive the beams emitted by the radiation source 152 and penetrate through the inspected vehicle. Slip ring 154 is driven by a drive mechanism to rotate to drive radiation source 152 and detector 153 to rotate around the vehicle.
[0052] As shown in Fig. 14, Fig. 15, Fig. 20, Fig. 21 and Fig. 22, the first drag means 111 includes a first support plate 1111, a first chain 114 (an example of an element traction element) and a first pushing element 1141 connected to the first chain 114, and the first pushing element 1141 moves around the first support plate 1111 to push the wheels to move along the first support plate 1111 , to drive a vehicle forward. The second drag means 112 includes a second support plate 1121, a second chain 114 (an example of the elongated pull element) and a second push element 1141 connected to the second chain 114 and the second push element 1141 moves in around the second support plate 1121 to push the wheels to move along the second support plate 1121 in order to drive the vehicle forward. See Fig.3, Fig.7, Fig.8, Fig.9, Fig.10 and Fig.11, the vehicle drag system also includes a controller (not shown), where the controller controls the first push element 1141 to push a first vehicle wheel at a first speed, when a second vehicle wheel arrives at a predefined position A of the second drag means 112, away from the separation section 113 at a predefined distance, the second chain 114 moves, therefore, the pushing element 1141 on the underside of the second support plate 1121 moves to contact the second wheel of the vehicle at a second speed and pushes the second wheel of the vehicle, in order to maintain the vehicle's movement state, and in the drag direction of vehicle E, the second wheel is located on the downstream side of the first wheel. The second speed can be greater than or equal to the first speed, and the second speed and the first speed can be basically constant. Before the first pushing element 1141 is separated from the first wheel, the second pushing element 1141 contacts the second wheel.
[0053] As shown in Fig. 3, the vehicle's drag system also includes a sensor 118 used to send a signal when the second wheel of the vehicle reaches the preset position A, and the sensor 118 is located in the preset position A of the second drag means 112, away from the separation section 113 for the predefined distance. After receiving the signal from sensor 118, the controller allows the second chain 114 to perform an accelerated movement and allows the second push element 1141 located on the underside of the second support plate 1121 to move for a preset time, touch the second vehicle wheel at second speed and push the second vehicle wheel. The sensor 118 can be a pressure sensor, a photoelectric sensor or a piezoelectric sensor or the like, and the pressure sensor, the photoelectric sensor or the piezoelectric sensor or the like is arranged in the predefined position A of the second drag means 112.
[0054] For example, as shown in Fig. 3, the vehicle moves from left to right, the pushing element 1141 of the first drag means 111 pushes the rear wheel of the vehicle, in order to allow the vehicle to move to the right in a first speed V position. When the vehicle's front wheel reaches sensor 117 arranged in the predefined position D, the pushing element 1141 in the second drag means 112 stops at a point S.
[0055] According to an embodiment of the present invention, when the front wheel of the vehicle reaches the preset position A, after receiving the signal from sensor 118, the controller allows the second chain 114 to execute an accelerated movement and then decelerate for the second speed. The accelerated movement may be a uniformly accelerated movement, and the decelerated movement may be a uniformly decelerated movement. The pushing element 1141 of the second drag means 112 performs an accelerated movement and accelerates to a speed V2 (V2> V), maintains speed V2 and then pushes the front wheel of the vehicle to move. Preferably, when the vehicle's movement speed becomes V2 speed, the beam emission frequency of an X-ray beam generation means 3 (or the stretching factor of a local image) is changed. For example, the ratio between the vehicle speed and the beam emission frequency is constant. Preferably, the system adopts a speed measurement means to track the speed of the vehicle when it moves from the first drag means 111 to the second drag means 112 and is activated in the second drag means 112, and, when the speed of the vehicle changes, the beam emission frequency of the X-ray beam generation medium 3 is changed. The accelerated movement of the pushing element 1141 can be a uniformly accelerated movement.
[0056] In the embodiment as illustrated in Fig. 1, the radiation source 152 includes the means for generating X-ray beams 3 and a beam collimator 4, and the beam emission range is shown by a dotted line as shown by the reference signal 5. According to a preferred embodiment of the present invention, the beam generation means include an electronic linear accelerator (for example, a 1.5 MeV electronic linear accelerator) or a machine X-ray. Preferably, the width of the inspection passage 101 is 3.5 m and its height is 4 m. Correspondingly, the width of the top of the vehicle that can be inspected by the vehicle inspection system disclosed by the present invention is not greater than 1.8 m, the width of the bottom of the vehicle is not greater than 2.4 m and the height it is not longer than 2m. Preferably, as shown in Fig. 1, the X-ray beam generating means 3 are arranged at the top of the scanning medium structure 80, and the beam collimator 4 is arranged at the bottom. When the vehicle enters inspection passage 101 and enters the main beam range 5 of the beams, the vehicle can be scanned by X-ray beams, and detector 153 placed underground receives the X-ray beams. Preferably, the detector 153 adopted here is a cadmium tungstate matrix detector of 5 mm x 2.5 mm, which acquires an image of the vehicle by means of vertical image transmission technology. Preferably, the scanning speed is 0.1 m / s or 0.2 m / s.
[0057] The vehicle inspected can be a small vehicle, for example, the vehicle can be a passenger car or bus.
[0058] The specific disposition parameters mentioned above and the means selected are merely used to exemplify the solutions of the present invention, instead of limiting the technical solutions of the present invention, those skilled in the art can select other parameters and means according to requirements these variations or medications are all within the scope of protection of the present invention.
[0059] As illustrated in Fig. 1, the vehicle inspection system revealed by the present invention can be integrated with a motorway toll station to perform safety inspection work on important transport stations, the reference signal 81 expresses islands on both sides of the inspection passage, and the safety islands 81 can be seen more clearly in Fig. 2. The inspection system described by the present invention can also be applied to locations in fields such as important buildings, areas activities or land border ports or similar, to perform security inspection work.
[0060] According to the preferred embodiment of the present invention, the first dragging means 111 and the second dragging means 112 are arranged on one side in the inspection passage 101 and can drag the vehicle driving into the passage inspection 101 to pass inspection 101. The first drag means 111 pushes the rear wheels of the vehicle and then the second drag means 112 pushes the front wheels of the vehicle, thus the separation section 113 is between the first drag medium 111 and the second drag medium 112. The path of the beams from the radiation source 152 to the detector 153 passes the separation section 113, in order to avoid the influence of the first drag medium 111 and the second drag medium 112 over a scanned image.
[0061] According to some embodiments of the present invention, the width of the inspection passage 101 is arranged in such a way that the vehicle can pass through the inspection passage 101 through the vehicle hauling system 100 and, meanwhile, the vehicle can pass inspection passage 101 along the ground without drag.
[0062] Specifically, see Fig. 2, direction E is the direction of travel of the vehicle. According to the preferred embodiment of the present invention, there is the condition that the vehicle, in dotted lines, is dragged to the exit of the inspection passage 101 by the vehicle drag system 100, the safety inspection is carried out on the vehicle , under the condition, an unmanned mode is adopted, the driver exits the vehicle at the starting point where vehicle 6 enters the first drag medium 111 and walks to the destination of the second drag medium 112 through a passage 10 to wait for the vehicle after inspection. The passage 10 is arranged on the rear side of the radiation protection walls 70, in order to prevent the driver from suffering radiation from the X-ray beams. Fig. 2 also shows another condition, that is, the vehicle is not dragged by the vehicle dragging system 100, but the driver quickly passes over the inspection passage 101 and the inspection system can choose to scan the vehicle by adopting a safe radiation dosage for the driver, or choose not to scan the vehicle. In other words, according to the technical solutions offered by the present invention, the vehicle inspection system has three modes in which the vehicle passes inspection passage 101. That is, different vehicles can be classified. Firstly, vehicles that do not require a safety inspection can pass without being dragged by the vehicle dragging system 100 and are triggered to pass quickly through inspection passage 101. Secondly, vehicles with a low safety risk cannot be dragged by the vehicle dragging system 100 and sweeping with a low radiation dose when they pass quickly through the inspection passage 101. Third, vehicles with a high safety risk are dragged by the vehicle dragging system 100 to pass through the passage inspection 101 for scanning with a standard radiation dosage, thus the efficiency of safety inspection work can be greatly improved and traffic jams are improved.
[0063] Preferably, a single drag medium here can be a drag medium for the car wash industry, namely, a single side wheel drag medium, since the drag medium has been commonly applied in the wash industry of cars, it can be introduced into the vehicle safety inspection field as a developed technology, so that repeated research and development in a vehicle locomotion medium is avoided. The drag medium is less laborious, saves energy and is environmentally friendly; a reel comes into contact with the wheels, generating minimal wear and collision in vehicles, consequently, it is easy to be accepted by owners and drivers.
[0064] In addition to the advantages mentioned above, the vehicle inspection system provided by the present invention can be built directly on the safety island of an existing toll station, so the civil engineering workload is small and the floor space is small. In addition, being similar to a small X-ray beam security baggage inspection machine, when the vehicle passes through an X-ray beam flow surface, a scanned image is automatically acquired in real time, thus Safety inspection efficiency and accuracy are greatly improved.
[0065] Fig. 3 shows a schematic diagram of a vehicle inspection system that includes the first drag means 111 and the second drag means 112. The separation section 113 is arranged between the first drag means 111 and the second drag means 112 and the beams 5 penetrate through the separation section to radiate detector 153.
[0066] Preferably, as shown in Figs. 2 and 3, the separation section 113 between the first dragging means 111 and the second dragging means 112 is provided with a platform 12, which is convenient for the vehicle to move in the separation section 113 between the first dragging means 111 and the second dragging means 112. The upper surface of the platform 12 and the ground plane in the inspection passage are at the same height. A space 115 can be formed in the middle of the platform 12, in order to prevent the collimator 4 beams for the detector 153 from being blocked to carry out an unprotected sweep of all the dragging means completely.
[0067] Alternatively, a material with the same thickness as that of the gap can be arranged in the gap 115 of platform 12 to improve the sealing property of the system. This has almost no influence on the scanned image, because a material of such thickness would add uniform backgrounds to the image. Obviously, the materials are selected considering, exhaustively, the loss of beam penetrability, the physical resistance and the price of the materials, for example, aluminum, iron, plastic and carbon fiber and other materials.
[0068] As shown in Figure 3, a swivel plate 13 facilitates the passage of the vehicle wheels and allows the pushing element 1141 in the second drag means 112 to pass, and the swivel plate 13 can rotate about an articulation axis . The axis is perpendicular to the extension direction of the second drag means 112 or to the E direction. Realization 2
[0069] A digitized vehicle passes through a scanning area at a constant speed, which will bring great inconvenience to the scanning control and data processing, and the purpose of the embodiment is to allow the vehicle to pass through the separation section 113 between the first drag means 111 and the second drag means 112 at a constant speed.
[0070] The structure of the system in the embodiment is shown in Fig. 1 and Fig. 2 as well, and the means of drag means as shown in Fig.4. The main difference between figure 4 and figure 3 is that an image acquisition means 14 is arranged on one side (adjacent to the first drag means 111) of the inspection passage 101 and is located close to the predefined position D.
[0071] As shown in Fig.4, the vehicle drag system also includes a sensor 118 used to send a signal when the second wheel of the vehicle reaches the memorized position A, and the sensor 118 is located in the memorized position A of the second drag means 112, away from the separation section 113 for the predefined distance. After receiving the signal from sensor 118, the controller allows the second chain 114 to perform an accelerated movement, and allows the second pushing element 1141, located on the underside of the second support plate 1121, to move for a predefined time , contact the vehicle's second wheel at second speed and push the vehicle's second wheel. The sensor 118 can be a pressure sensor, a photoelectric sensor or a piezoelectric sensor or the like, and the pressure sensor, the photoelectric sensor or the piezoelectric sensor or the like is arranged in the predefined position A of the second drag means 112.
[0072] As shown in Fig.4, the vehicle drag system also includes a means of acquiring wheel diameter used to measure the diameter of the second wheel of the vehicle, and a means of calculating, in which the means of calculation is used to calculate a required travel distance for the second pushing element 1141 to reach the second wheel and contacting the second wheel, according to the diameter of the second wheel acquired by the vehicle diameter acquisition means and the position of the second pushing element 1141, located on the underside of the second support plate 1121. The wheel diameter acquisition means may include an image acquisition means, and the image acquisition means is used to acquire two images, including the second wheel on the predefined time interval, and calculate the diameter of the second wheel of the vehicle according to the travel distances of the vehicle in the two images, the first speed of the vehicle, the diameters of the second wheel of the vehicle c with images and time interval. The image acquisition means, which can be a camera or video camera 14, is arranged in the predefined position D of the first dragging means 111, away from the separation section 113 by a predefined distance and is located on one side of the first means of drag 111.
[0073] For example, as shown in Fig.4, the vehicle moves from left to right, the pushing element 1141 of the first drag means 111 pushes the rear wheel of the vehicle in order to allow the vehicle to move to the right at the first speed V. When the front wheel of the vehicle reaches the sensor 117 arranged in the predetermined position D (ground) the pushing element 1141 in the second drag means 112 stops at point S, and the camera or video camera 14 starts photographing the vehicle. After a short time t, the vehicle is photographed again. The camera or video camera 14 can clearly photograph the front wheel of the vehicle and the area in the vicinity.
[0074] As shown in Figure 5, the camera or video camera 14 shoots a photo of the inspected vehicle and takes a photo again at a time interval t. The vehicle moves at speed V, and the vehicle advances a distance Vt within time t. The outer diameter of the vehicle's front wheel is measured on the photograph, and the vehicle's movement distances are measured on two photographs, in this way, two measurements can be performed manually on the photographs, and can also be processed automatically by using a image processing algorithm. The outside diameter of the vehicle's front wheel:

[0075] In this way, the outer diameter of the front wheel of the vehicle can be measured, and the measurement of the outer diameter of the front wheel is very important for the second pushing element 1141 in the second drag means 112 to contact the vehicle wheel at a programmed speed. Of course, under the condition that the outer diameter of the front wheel is known, the travel speed can be measured in return. Alternatively, under the condition that the outside diameter of the front wheel and the travel speed is known, the time interval is measured by technology. The method is subject to expansion to various fields, such as size measurement, speed measurement, time measurement and the like, and the measurement object is not limited to vehicles or wheels. In addition, the purpose of improving accuracy can be accomplished by improving the measurement accuracy of each parameter, selecting multiple data measurement points or photographs multiple times.
[0076] Obviously, the type of vehicle identification or other methods for measuring the diameter of the front wheel can replace the photo measurement method mentioned above to complete the front wheel diameter measurement step in the present invention. However, the trigger measurement method has the advantages of low cost, developed equipment technology, economy of occupied area, and the like.
[0077] As shown in figure 6, under the condition that the pushing element 1141 is a roller, after the diameter of the front wheel is measured, when the pushing element 1141 of the second drag means 112 pushes the front wheel, the relative distance between them can be calculated accurately. If the diameter 2R of the front wheel and the radius r of the pushing element 1141 are known, it can be obtained that

[0078] For example, when the front wheel of the vehicle reaches sensor 118 in the memorized position A, the pushing element 1141 of the second drag element 112 performs the accelerated movement and accelerates at a speed V3 (V3> V), and it gradually decelerates to speed V and then pushes the front wheel of the vehicle to move. The movement speed-time relationship of the pushing element 1141 of the second drag means 112 is preferably as shown in figure 7 (A). The pushing element 1141 accelerates to speed V3 from a static state after a time t1 and decelerates to V after a time t2. As shown in Fig.4, the distance from S to position A is L. The pushing element 1141 follows the front wheel and needs to travel a distance L-a more than the vehicle. The pushing element 1141 moves according to the speed-time curve as shown in Fig.7, L-a = 0.5x [V3xtl + (V3 + V) xt2] -Vx (tl + t2) (3)
[0079] V3, tl and t2 can be designed according to need, but before the rear wheel reaches platform 12, as shown in Figure 4, the pushing element 1141 must reach the front wheel at speed V. In addition , the measurement of L can be calculated by the precise size of the second drag means 112 and can also be deduced according to the time interval of the pushing element 1141 to pass through position S and position A, at a constant speed, and can be used as a system parameter.
[0080] Preferably, the accelerated and decelerated movement of the pushing element 1141 are uniformly accelerated movements and uniformly decelerated movements.
[0081] It is obvious that the pushing element 1141 can follow the front wheel according to other speed-time curves, for example, according to Fig. 7 (B). When the vehicle's front wheel reaches the default position A, the pushing element 1141 accelerates to speed V3, advances constantly at speed V3 and then decelerates V and reaches the front wheel of the vehicle. According to the above, a kinematic formula can be obtained, and will not be repeated here. In fact, according to the properties of an engine and adopting a specific speed-time curve, several ways of following can be conceived, including variable acceleration, as long as the distance L-a is obtained.
[0082] In the solution of the embodiment, the vehicle's movement speed is maintained in V and the frequency of the X-ray beam generation medium 3 is not necessarily changed, so that the beam emission and the complexity of detection system control are reduced. Realization 3
[0083] In mode 2, it is noticed that the vehicle passes the separation section 113 at constant speed and the dragging means do not protect the sweeping beams. The method for measuring the outer diameter of the wheel is also provided. However, the system is somewhat complicated, including the fact that the distance L, as shown in Fig. 4, has to be measured. In embodiment 3, based on the measurement of the outer diameter of the wheel, the vehicle is kept moving at constant speed, and the L value does not need to be measured.
[0084] In comparison to embodiment 2, the important modification in the implantation of the system is made as follows: the image acquisition medium 14 is changed from the preset position D to a position close to the preset position A and is adjacent to one side of the entraining medium, as shown in Fig.8.
[0085] As shown in Fig.8, the vehicle drag system also includes a distance acquisition apparatus used to measure the distance between the second vehicle wheel and the second pushing element 1141, when the second vehicle wheel arrives to the predefined position A of the second drag means 112, away from the separation section 113 for the predefined distance, the distance acquisition device acquires the distance between the second wheel and the second pushing element 1141 to serve as the required travel distance for the second pushing element 1141 to reach the second wheel and contact the second wheel.
[0086] See Fig. 8, the distance acquisition device may include an image acquisition means, in which the image acquisition means 14 is used to acquire two images, including the second wheel and the second pushing element 1141. at a predefined time interval, and calculate the distance between the second wheel and the second pushing element 1141 according to the travel distances of the vehicle in the two images, the distance between the second wheel and the second pushing element 1141, the first vehicle speed and time interval. The image acquisition medium can be a video camera or camera, it can be arranged in the predefined position A of the second drag medium 112, away from the separation section 113 for the predefined distance and is located on one side of the second drag medium 112.
[0087] In this way, the image acquisition means can be used not only to acquire the diameter of the second wheel of the vehicle, but also to acquire the distance between the second wheel and the second pushing element 1141, and the distance is the basis for calculating the travel distance required for the second pushing element 1141 to reach the second wheel and contact the second wheel. It is not difficult to understand that an exact distance, in which one element will follow the other, must be acquired by subtracting the distance in the direction of travel of the vehicle from the second wheel and the second pushing element when the second wheel contacts the second pushing element from the distance (for these circular pushing elements, like a pushing roller, is the a in formula (2)).
[0088] As shown in Fig.8, the vehicle drag system also includes a sensor 118 used to send a signal when the second wheel of the vehicle reaches the predefined position A, away from the separation section 113 for the predefined distance of the second drag means 112, after receiving the signal from sensor 118, the controller operates the distance acquisition apparatus to acquire the distance between the second wheel and the second pushing element 1141. The sensor 118 can be a pressure sensor, a photoelectric sensor or a piezoelectric sensor or the like, and the pressure sensor, the photoelectric sensor or the piezoelectric sensor or the like is arranged in the predefined position A of the second drag means 112.
[0089] Preferably, as shown in Fig.8, the vehicle moves from left to right, the pushing element 1141 of the first drag means 111 pushes the rear wheel of the vehicle in order to allow the vehicle to move to the right at the first speed V. When the speed of the front wheel of the vehicle reaches the first sensor 117, arranged in the predefined position D, the pushing element 1141 in the second drag means 112 stops at point S and begins to start a V4 speed (V4> V). When the front wheel of the vehicle reaches the second sensor 118 (the photoelectric sensor or the piezoelectric sensor) in the second predefined position A, the vehicle and the front wheel of the vehicle are photographed, as shown in Fig. 9A. When the pushing element 1141 in the second drag means 112 reaches the second sensor 118 in the memorized position A, the vehicle and the front wheel thereof are photographed again, as shown in Fig. 9B. A system timer (not shown) records the time interval t 'of two photographs. Similar to the previous principle for measuring the 2R diameter outside the front wheel, it is easy to acquire:
during the second photograph, the distance between the pushing element 1141 and the front wheel of the vehicle is measured on the photograph as well. So, the actual distance b between the pushing element 1141 and the front wheel of the vehicle satisfies a formula:
wherein the pushing element 1141 must travel a distance ba to reach the front wheel of the vehicle (a is acquired by replacing the R calculated in formula (4) in formula (2)).
[0090] When the pushing element 1141 reaches the preset position A, the pushing element 1141 begins to decelerate evenly at speed V after a time t3 and reaches the front wheel of the vehicle (as shown in Fig. 9C) , the speed-time curve is as illustrated in Fig. 10A, it can be known that: ba = 0.5x (V4-V) t3 (6) the acceleration is equal to P = (V-V4) / t3 (7)
[0091] From when the front wheel reaches the preset position A until the pushing element 1141 reaches the front wheel, the vehicle's movement distance is equal to V (t '+ t3). As shown in Fig.8, the space from the end of the first drag means 111 to the predefined position A is g. In order to ensure that, before the first pushing element 1141 of the first drag means 111 is separated from the first wheel (for example, the rear wheel), the second pushing element 1141 of the second drag means 112 contacts the second wheel ( for example, the front wheel), it is assumed that the minimum space between the front and rear wheels of all common vehicles is equal to M, then V (t '+ t3) + g <M (8) and this condition must be satisfied in the system design.
[0092] The system parameters and control parameters are designed according to formulas (6) - (8): the acceleration p, the speed V4, the time intervals t ', t3 and intermediate calculation are completed by the formulas ( 4) - (5). Therefore, the vehicle can pass through the separation section 113 steadily at a constant speed.
[0093] Obviously, the speed-time curve of the pushing element 1141 can be changed from Fig.lOA to Fig.lOB, that is, after reaching the preset position A, the pushing element 1141 continues to move for a while t4 at constant speed, then decelerates evenly to speed V after a time t5 and reaches the front wheel of the vehicle. This way facilitates the acceleration of the progress of an element to reach the other. The additional time parameter is adjustable, thus increasing the system's design flexibility. Obviously, the solution is a little more complicated to control than the solution as shown in Fig.10A. In fact, the pushing element 1141 can chase the front wheel according to several speed-time curves, including variable accelerated motion, as long as the speed of the pushing element 1141 is equal to the speed of the vehicle, when the pushing element reaches the wheel forward.
[0094] In the embodiment, the positioning of the preset position D and the preset position S are not necessarily very accurate, therefore, the cost of the system can be further reduced.
[0095] As shown in Fig.8, in order to allow the vehicle to pass, stably, the separation section 113 between the first drag means 111 and the second drag means 112, a pedal 15 can be disposed in the system. When the front wheel reaches the preset position D, pedal 15 is extended to allow the front wheel to pass steadily. Pedal 15 is retracted after the front wheel has passed. Naturally, pedal 15 can be omitted on the condition that the requirement for stable travel of the vehicle is not particularly high or that the diameter of the pushing element 1141 is small enough.
[0096] In reality, by means of the speed-time curve and the technology of the present invention, the pushing speeds of the vehicle of the first drag means 111 and the second drag means 112 can be controlled at random, in order to satisfy a variety of application requirements. Realization 4
[0097] The drag system in embodiments 1, 2 and 3 is applied to a perspective scanning imaging system without shielding against the beams. As mentioned above, the radiographic inspection system in the present invention can include a CT scanning system, as shown in Fig.11. The radiation source 152 and detector 153 are installed on the sliding ring 154. The drag system in the present invention can also be applied to a nuclear magnetic resonance imaging system, to avoid the influence of the drag medium on the imaging.
[0098] As shown in Fig.12, the vehicle drag system also includes a sensor 81, in which sensor 81 is arranged on the second pushing element 1141 and is used to detect whether the second pushing element 1141 was in contact with the second wheel (for example, the front wheel) of the vehicle. The sensor can be a contact sensor, a pressure sensor, a piezoelectric sensor or the like. The vehicle drag system also includes a feedback means 82. The sensor detects whether the second pushing element 1141 has been in contact with the front wheel and notifies the vehicle inspection system controller via a connected feedback means 82 . After receiving the signal that the second pushing element 1141 was in contact with the second wheel (for example, the front wheel) of the vehicle, the vehicle inspection system controller can control the second drag means 112 to push the vehicle at a speed greater than that of the first drag means 111. As a preferable alternative solution, after receiving the signal that the second pushing element 1141 was in contact with the second wheel (for example, the front wheel) of the vehicle, the vehicle inspection system can control the second drag means 112 to push the vehicle at a speed equal to the speed of the first drag means 111, i.e., drag the vehicle at a constant speed. Apparently, in the solution, image acquisition 14, as shown in Fig.8, can be omitted, and even sensor 117 in preset position D and sensor 118 in preset position A, as shown in Fig.8, are omitted .
[0099] Preferably, sensor 81 is a piezoelectric sensor. Preferably, the feedback means includes a radio signal emission unit used to send the signal to the vehicle inspection system controller.

The vehicle inspection system further includes a controller, in which the controller corrects an acquired image of the inspected vehicle according to a scanned image obtained by the vehicle inspection system when the drag medium is unloaded, in order to remove the image of the drag medium from the acquired image of the inspected vehicle, for example, the controller corrects the acquired image of the inspected vehicle in accordance with the scanned image acquired by the vehicle inspection system when the hauling medium is unloaded, in order to remove the image of at least part of the chain and the push element from acquired image of the inspected vehicle. The controller can correct the acquired image of the inspected vehicle according to the position of the inspected vehicle and at least part of the chain and the push element along the direction of travel of the vehicle, in order to remove the image of at least part of the chain and the pushing element from the acquired image of the inspected vehicle.
