The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without any inventive step, are within the scope of the present invention.
Techniques, methods, and apparatus known to those of ordinary skill in the relevant art may not be discussed in detail but are intended to be part of the specification where appropriate.
In the description of the present invention, it should be understood that the terms "first", "second", etc. are used to define the components, and are used only for the convenience of distinguishing the corresponding components, and if not otherwise stated, the terms have no special meaning, and thus, should not be construed as limiting the scope of the present invention.
In addition, the technical features involved in the different embodiments of the present invention described below may be combined with each other as long as they do not conflict with each other.
Fig. 1 shows an embodiment of the present invention. Referring to fig. 1, the inspection system provided by the present invention includes:
a radiation source device movably disposed and including a radiation source 1, the radiation source 1 for radiating a ray passing through an object a to be inspected; and
the detection device is arranged to move synchronously with the radiation source device and comprises a detector 4, and the detector 4 is used for detecting the ray radiated by the radiation source and passing through the object a to be detected.
And wherein: at least part of the radiation source 1 is located below a target bearing surface for bearing an object a to be examined.
Based on the scheme, the invention can realize the scanning process that the detected object a does not move but the ray source 1 moves based on a simpler structure, and can eliminate the influence of a conveying device on the imaging quality because the conveying device is not required to drag the detected object a.
Meanwhile, since both the radiation source device and the detection device of the present invention are provided to be movable, it is also possible to conveniently realize a one-time inspection process for a plurality of inspected objects a by sequentially arranging the plurality of inspected objects a at intervals in the moving direction. Since a plurality of detected objects a can be imaged in one scanning process, the scanning efficiency is higher. Therefore, the arrangement mode of the invention is also beneficial to improving the scanning efficiency.
Moreover, the plurality of inspected objects a arranged along the moving direction can be different types of the same kind of articles, for example, vehicles of different vehicle types, even completely different types of articles such as vehicles and containers, and therefore, the requirement of scanning different types and/or different types of inspected objects a at a time can be conveniently met.
In the scanning process of the inspection system, the object a to be inspected can be directly positioned on the ground, and at the moment, the bearing surface of the object is the ground; alternatively, the object bearing device 6 may be provided in the inspection system, and the object a to be inspected may be positioned on the object bearing device 6, in which case the object bearing surface is the upper surface of the object bearing device 6. Under the condition that the target bearing device 6 is used for bearing the target a to be detected, the radioactive source 1 can be arranged below the bearing surface of the target more conveniently, meanwhile, the arrangement of the relative position relation between the radioactive source 1 and the detector 4 is facilitated, the detector 4 can receive ray signals more sufficiently, and further, the higher-quality image can be obtained.
The invention will be further described with reference to the embodiment shown in fig. 1.
For convenience of description, only the object to be inspected a is taken as a vehicle as an example, and the inspection system at this time may be referred to as a vehicle inspection system. The object a to be inspected can be understood by reference to the case where it is another object such as a container or a trunk.
Meanwhile, the moving direction of the radiation source device and the detecting device is hereinafter referred to as a front-rear direction, and a direction perpendicular to both the up-down direction and the moving direction is hereinafter referred to as a left-right direction, to simplify the description.
As shown in fig. 1, in this embodiment, the inspection system includes a radiation source device, a detection device, and a target carrying device 6, and the radiation source device includes a radiation source 1, a collimator 2, and a first carrying device 3; the detection device comprises a detector 4 and a second bearing device 5; the object carrying device 6 comprises a first support device 61 and a second support device 62.
As can be seen from fig. 1, the first supporting device 61 and the second supporting device 62 are both supporting platforms, and the two supporting platforms are fixed on the ground at intervals along the left-right direction and are used for jointly supporting the vehicle to be detected. The space between the two supporting platforms is adapted to the space between the wheels on the left and right sides of the vehicle, so that the wheels on the left and right sides of the vehicle can be respectively positioned on the upper surfaces of the two supporting platforms in the scanning and checking process. On this basis, the target carrier device 6 functions as a carrier vehicle, supporting the vehicle at a height above the ground, which facilitates the arrangement of the radiation source device; moreover, the target bearing device 6 is not movable in the front-back direction, so that the vehicle does not move any more in the scanning process, but keeps stationary in the front-back direction, which is also convenient for scanning different parts of the detected vehicle in the front-back direction when the radioactive source 1 and the detector 4 move. It will be understood that in this embodiment, the upper surface of the support platform is the target bearing surface for bearing the vehicle (object a to be inspected). Of course, the first support device 61 and the second support device 62 may also be in other forms of structures than support platforms.
The radiation source 1 is used for radiating rays capable of penetrating through the vehicle for being received by the detector 4, so that the inspection system can reflect the change of the density distribution of the vehicle according to the change of the intensity of the rays, and the intensity of the rays is converted into image gray scale to obtain a perspective image of the vehicle. The radiation source 1 of this embodiment may be, for example, an X-ray machine for emitting X-rays. And the radioactive source 1 of the embodiment can be provided with an exit shielding device, so that the exit shielding device can be utilized to effectively control the exit beam direction and the exit beam range and play a certain role in radiation protection. Preferably, the exit shield can be integrated with the X-ray machine and have a fixed opening or an opening with an adjustable size.
The collimator 2 plays a role in beam limiting and collimating rays radiated by the radioactive source 1, so that effective ray beams meet the requirement of initial width in a preset direction, the radiation protection capability of the system is improved, secondary calibration is carried out on the ray beams, and the control precision of effective beam limiting is improved. As can be seen from fig. 1, the collimator 2 is arranged corresponding to the radiation source 1 and above the radiation source 1.
The first bearing device 3 provides an installation foundation for the ray source 1, the collimator 2 and the like, and can drive the ray source 1, the collimator 2 and the like to move along the front-back direction. As shown in fig. 1, in this embodiment, the first carrying device 3 is a trolley, and the radiation source 1 and the collimator 2 are both disposed on the trolley, so that when the trolley moves in the front-back direction under the action of its wheels, the radiation source 1 and the collimator 2 also move in the front-back direction together, and the radiation source 1 can irradiate different positions of the vehicle in the front-back direction under the driving of the first carrying device 3.
As can be seen from fig. 1, in this embodiment, two radiation sources 1 and two collimators 2 corresponding to the two radiation sources 1 one to one are disposed on the first carrier 3, wherein the two radiation sources 1 are respectively located at two sides of a vertical central axis (i.e., a bilateral symmetry central line, which is aligned in a left-right direction with a vertical central axis of a vehicle parked on the target carrier 6) of the first carrier 3, which is beneficial to cooperate with the detection apparatus of this embodiment to achieve more omni-directional scanning of the vehicle. Although this embodiment shows that the number of the radiation sources 1 and the collimators 2 is two, it should be understood that in other embodiments, the number of the radiation sources 1 and the collimators 2 may be 1 or more.
In addition, as shown in fig. 1, in this embodiment, at least a part of the radiation source 1 is located below a target bearing surface for bearing an object a to be examined, specifically, the first bearing device 3 is disposed in a pit depressed downward from the ground between two support platforms such that a main portion of the radiation source 1 is located below the target bearing surface (i.e., the upper surface of the support platforms) and the radiation center of the radiation source 1 is located at a height position where the target bearing surface is located, in other words, the radiation center of the radiation source 1 is flush with the target bearing surface in the height direction. In this regard, the radiation source device is arranged below the vehicle and between two support platforms, such that the radiation source 1 is positioned underneath, so that during scanning the radiation source 1 can irradiate the vehicle carried on the object carrier 6 from below up. In particular, in fig. 1 the first carrier 3 is only partly located in the pit, but in practice the first carrier 3 may also be located entirely in the pit.
The detector 4 is used for receiving the rays emitted by the radiation source 1 and penetrating through the vehicle, and converting the received rays into electric signals which can be recorded so as to be used by an imaging device of the inspection system for generating images. The detector 4 of this embodiment is arranged inside the arm support of the second carrier 5 and receives the active rays emitted by the radiation source 1 and collimated by the collimator 2.
The second bearing device 5 bears the detector 4 and can drive the detector 4 and the like to move synchronously with the ray source 1. As shown in fig. 1, in this embodiment, the second carriage 5 includes two vertical arms 51, a cross arm 52 connected between upper portions of the two vertical arms 51, and a traveling mechanism (specifically, wheels 53) provided below the two vertical arms 51. Based on this, a space for accommodating the vehicle (object a to be inspected) is formed between the cross arm 52 and the two vertical arms 51.
Further, although the detector 4 may be disposed on only one of the horizontal arm 52 and the vertical arm 51, in order to realize a full-scale scan of each angle of the entire vehicle, the horizontal arm 52 and the two vertical arms 51 of the embodiment are each provided with the detector 4, and each arm is provided with a plurality of detectors 4, and the plurality of detectors 4 are disposed at a certain angle to form a detector array. Based on this, the second bearing device 5 of this embodiment includes a movable gantry structure, an internal region defined by the gantry structure forms a scanning region, the target bearing device 6 and the radiation source device are both located in the scanning region, and the wheels 53 of the second bearing device 5 can drive the detector 4 to move synchronously and equidirectionally with the radiation source 1 under the driving action of the power mechanism (e.g., a motor), so that the detector 4 can be coplanar with the radiation source 1, and thus in the process that the radiation source 1 irradiates different parts of the vehicle in the front-back direction, the detector 4 can receive the radiation well, and the full scanning of different parts of the entire vehicle is realized. The power mechanisms of the first carrier device 3 and the second carrier device 5 can be operated synchronously at the same rotation speed under the control of an electric control device. Alternatively, the synchronization precision of the movement of the first bearing device 3 and the second bearing device 5 may be further improved by providing a speed feedback device, for example, the rotation speeds of the power mechanisms of the first bearing device 3 and the second bearing device 5 may be monitored and fed back to the control device to realize closed-loop control, so as to further improve the consistency of the rotation speeds of the power mechanisms of the first bearing device and the second bearing device, and further improve the coplanarity of the detector 4 and the radiation source 1. Wheels 53 may be universal wheels or rail wheels, rolling directly on the ground, or rolling on rails.
Moreover, as can be seen from fig. 1, in this embodiment, the second supporting device 5 is disposed on the ground, and the bottom end of the detector 4 located at the lowest portion in the detector array on the vertical arm 51 is located at approximately the same height position as the radiation center of the radiation source 1, which is beneficial to increasing the radiation receiving rate and realizing a more sufficient receiving process of the radiation emitted by the radiation source 1 by the detecting device.
In addition, in order to keep the radiation source 1 and the detector 4 in a good matching relationship during the moving process, the inspection system of the embodiment is further provided with a first adjusting device and a second adjusting device.
Wherein the first adjusting device is arranged on the first carrier 3 and is used for adjusting at least one of the angle of the radiation source 1 and the position of the radiation source 1 on the first carrier 3. For example, the first adjustment means may be arranged to be able to adjust the angle of the radiation source 1 and its position on the first carrier 3 simultaneously. Like this, at radiation source device 1 removal in-process, can utilize first adjusting device to carry out the position to radiation source 1 and adjust for the ray that radiation source 1 radiated can be just to the detection face of detector 4 all the time, and the direction of irradiation of radiation source 1 remains the position that can be received by detector 4 well all the time, thereby realizes more high-efficient high-quality scanning process.
And the second adjusting device is used to adjust the detector 4 so that the detection surface of the detector 4 is facing the radiation emitted by the radiation source 1. Based on the adjustment of the second adjusting device to the detector 4, the good matching relationship between the radiation source 1 and the detector 4 in the moving process is also facilitated, so that the intensity of the ray signal received by the detector 4 is strongest, and a more efficient and high-quality scanning process is realized. The second adjusting device can adjust the position and angle of the bracket connecting the detector 4 to the second bearing device 5, or adjust the cross arm 52 and/or the vertical arm 51 (for example, adjust the angle of the cross arm 52 and/or the vertical arm 51) to make the detecting surface of the detector 4 face the rays emitted by the ray source. Due to the large number of detectors 4, the second adjusting device for adjusting the cross arm 52 and/or the vertical arm 51 can have a simpler structure, and can also achieve synchronous adjustment of the detectors 4 more easily, and the synchronization precision is higher, compared with the mode of adjusting the support corresponding to each detector 4.
The first adjusting device and/or the second adjusting device may include at least one of a slide rail mechanism, a cylinder mechanism, a rotating mechanism such as a motor, and the like, for example, to achieve the adjustment of the position and/or the angle.
Of course, alternatively, only one of the first adjusting device and the second adjusting device may be provided to achieve a good fit between the radiation source 1 and the detector 4 during the movement.
When the inspection system works, a vehicle to be inspected can be driven to a supporting platform to park, then the first bearing device 3 and the second bearing device 5 are controlled to move synchronously and in the same direction, so that an effective fan-shaped beam emitted by the ray source 1 is coplanar with the collimator 2 and the detector 4, a movable fan-shaped beam surface is formed to pass through the vehicle to be inspected, one-time scanning operation is completed, and the inspection of the whole vehicle is realized.
The crossbar 52 and the vertical arm 51 in the second carrier 5 are rigidly connected, and before the inspection system is operated, the three arms are adjusted to be in the same plane, so that the probes 4 on the crossbar 52 and the vertical arm 51 are in the same plane.
Moreover, although only one vehicle to be inspected is shown in fig. 1, the size (referred to as length for short) of the supporting platform in the front-back direction of the embodiment may be set to be suitable for two or more vehicles to be inspected according to needs, so that the inspection system of the embodiment can complete scanning of a greater number of vehicles of more vehicle types in one scanning process, improve scanning efficiency, and meet more diverse scanning requirements. Or, a plurality of groups of supporting platforms which are spaced from each other can be arranged in the moving direction, a plurality of vehicles to be detected are respectively placed on each group of supporting platforms along the length direction, and the inspection system of the embodiment can also complete the scanning of vehicles with more quantity and more vehicle types in one scanning process. In the process of completing the scanning of more than two vehicles at one time by using the inspection system of the embodiment, different vehicles can be distinguished based on images, or the distinguishing of the scanning results of different vehicles can also be realized by a light curtain or a segmented parking area.
It can be seen that this embodiment has the following beneficial effects:
(1) the radioactive source 1 is arranged at the bottom, the detector 4 is arranged at the top, and the radioactive source 1 and the detector 2 are integrally moved, so that the immobilization of the detected vehicle can be conveniently realized, the scanning and checking process can be conveniently finished without a vehicle conveying device, the influence of the stop and the movement of the detected vehicle in the dragging process of the detected vehicle by the vehicle conveying device on the image quality can be further avoided, and the problem of poor image quality caused by the arrangement of the detector at the bottom and the arrangement of the conveying device is fundamentally solved.
(2) Compared with the scheme that the detector is arranged at the bottom and the radioactive source is arranged at the top, the radioactive source 1 is arranged at the bottom and the detector 4 is arranged at the top, so that the scanning mode is more flexible, a plurality of vehicles can be conveniently and simultaneously detected, and the scanning process with higher efficiency is realized.
(3) The inspection device of the embodiment has the advantages of simple structure, low cost and convenient maintenance of the radioactive source device and the detection device.
Fig. 1 shows only one embodiment of the inspection system of the invention, but in practice the inspection system of the invention may also take other forms of construction than that of fig. 1.
For example, the first carriage 3 may be directly installed on the ground without being installed in a pit, as one of them. By raising the height of the target-carrying means 6 and wheels 53, it is still possible to position the source 1 below the target-carrying surface, with the center of the source 1 flush with the bottom end of the lowermost detector 4 in the detector array.
For another example, the target bearing device 6 may not be provided, but the target a to be detected may be directly located on the ground, at this time, the pit where the first bearing device 3 is located may be dug to a deeper depth, so that the radiation source 1 is located below the target bearing surface, and the pit may also be provided below the vertical arm 51 and the wheel 53 may be placed in the corresponding pit, so that the center of the radiation source 1 and the bottom end of the lowest detector 4 in the detector array may still be kept flush.
The above description is only exemplary of the present invention and should not be taken as limiting the invention, as any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
