As shown in fig. 2, in a specific use, in a first step, the first moving portion 1 is moved to a first side of the object 10 to be detected, so that the X-ray machine 2 mounted on the first moving portion 1 emits X-rays toward the object 10 to be detected, and the X-rays pass through the object 10 to be detected. And secondly, moving the second moving part 3 to a second side of the article 10 to be detected, so that the detector 4 arranged on the second moving part 3 corresponds to the position of the X-ray machine 2 to receive the X-ray passing through the article 10 to be detected, and thus, the article type of the covered area is judged according to the received X-ray signal intensity. And thirdly, controlling the first moving part 1 and the second moving part 3 to synchronously move along the first direction, thereby acquiring a whole continuous perspective view to judge whether the dangerous goods exist according to the whole perspective view.
In the above embodiment, preferably, the first moving part 1 and the second moving part 3 are both moving trolleys, the bottom of the first moving part 1 is provided with four first driving wheels 11, and the bottom of the second moving part 3 is provided with four second driving wheels 31. The first driving wheel 11 and the second driving wheel 31 are respectively connected with different driving motors, and the driving motor on the first driving wheel 11 is in communication synchronization with the driving motor on the second driving wheel 31, so that each driving motor can drive the first driving wheel 11 and the second driving wheel 31 to move synchronously, and the detector 4 can accurately receive the X-ray passing through the object to be detected 10 in the moving process. It is understood that in other embodiments, the first moving part 1 and the second moving part 3 may be adaptively replaced with other moving devices (e.g., a mobile robot). The split design can lead the whole X-ray detection system to flexibly adjust the position and the movement mode along with the size and the shape of the object 10 to be detected, is not limited by the length of the connecting rod and the working site in the security inspection process, and greatly improves the working flexibility and the field adaptability.

Moreover, the detector 4 may be a line array detector or an area array detector, so as to perform adaptive selection according to different detection requirements.
< second embodiment >
Fig. 3 and 4 show an X-ray detection system according to a second embodiment of the present invention. Compared with the first embodiment, the present embodiment is different in that: both the X-ray machine 2 and the detector 4 can be moved.
Specifically, the X-ray device 2 is disposed on the first moving portion 1 so as to be movable back and forth along a second direction (i.e., a Y-axis direction in fig. 3), and the detector 4 is disposed on the second moving portion 3 so as to be movable back and forth along the second direction. The X-ray machine 2 and the detector 4 move synchronously, and the second direction is perpendicular to the first direction. It can be understood that, in the present embodiment, while the first moving portion 1 drives the X-ray machine 2 to move along the first direction, the X-ray machine 2 can also move back and forth in the second direction, so as to cover a larger detection area. Similarly, while the second moving part 3 moves the detector 4 in the first direction, the detector 4 can also move back and forth in the second direction, so that the X-ray of a larger detection area can be received.
As shown in fig. 4, in the above embodiment, it is preferable that the first moving portion 1 is provided with the first main bracket 7 along the second direction, the first sub-bracket 8 is movably mounted on the first main bracket 7 along the second direction, and the X-ray machine 2 is movably mounted on the first sub-bracket 8 along the second direction, so that the X-ray machine 2 can adjust the height in the Y-axis direction, thereby facilitating the storage of the X-ray machine 2. Similarly, the second main support 5 is arranged on the second moving part 3 along the second direction, the second secondary support 6 is movably mounted on the second main support 5 along the second direction, and the detector 4 is movably mounted on the second secondary support 6 along the second direction, so that the height of the detector 4 can be adjusted in the Y-axis direction, and the detector 4 can be conveniently stored. Wherein, X-ray machine 2 accomodates the scope the same with detector 4's the scope of accomodating to make X-ray machine 2 and detector 4 accomodate the back still can the mutual correspondence, guarantee detection effect.
In the above embodiment, the housing manner of the X-ray unit 2 and the housing manner of the detector 4 are the same, and therefore, only how the detector 4 is housed will be described. As shown in fig. 3, in detail, the second main support 5 is mounted on the upper surface of the second moving portion 3 along the second direction (i.e., the Y-axis direction), and a main slide rail 51 is provided on the second main support 5 along the Y-axis direction, and a main slider 52 is slidably connected to the main slide rail 51. The second secondary support 6 is arranged along the Y-axis direction and is parallel to the second main support 5, a first mounting block 61 is arranged on one side of the second secondary support 6 close to the second main support 5, and the second secondary support 6 is fixed on the main slide block 52 through the first mounting block 61, so that the second secondary support 6 can be in sliding fit with the main slide rail 51 through the main slide block 52 and can move back and forth in the Y-axis direction relative to the second main support 5. Moreover, a secondary slide rail 62 is arranged on one side of the second secondary support 6 far away from the second main support 5, and a secondary slide block 63 is connected on the secondary slide rail 62 in a sliding way. The detector 4 is fixed to the sub-slider 63 by the second mounting block 41, thereby enabling the detector 4 to reciprocate in the Y-axis direction with respect to the second sub-mount 6. It can be understood that, when the second secondary support 6 moves to the top along the Y-axis direction, the height of the detector 4 is the total height of the second primary support 5 and the second secondary support 6, and in this state, the detector 4 is in the unfolded state; when the second support 6 moves to the bottom along the Y-axis direction, the height of the detector 4 is only the height of the second support 5, and in this state, the detector 4 is in the storage state. Thus, the detector 4 can be unfolded during use to improve the detection range; and to house the probe 4 when not in use for ease of transport and transfer.
In addition, it is understood that the above embodiment is only exemplified by two-stage storage, and in other embodiments, the height adjustment may be performed by three-stage or four-stage multi-stage storage. The size of the detector 4 can be smaller by adopting a multi-section type receiving mode, but the overall structure is slightly complex, and the size can be adaptively selected according to actual requirements.
As shown in fig. 5, the X-ray unit 2 can reciprocate in the Y direction to adjust the range of the irradiation area. Therefore, in the present embodiment, the irradiation length of the X-ray machine 2 in the X-axis direction is smaller than the overall length of the region to be detected 30, and the irradiation width in the Y-axis direction is smaller than the overall width of the region to be detected 30, so that the single irradiation area 20 of the X-ray machine 2 only covers a small part of the region to be detected 30, and the detection effect is improved. With the movement of the X-ray machine 2 in the X-axis and Y-axis directions, the radiation area of the X-ray machine 2 completely covers the area to be detected 30, so as to complete the detection of the area to be detected 30.
As shown in fig. 5, the single irradiation area 20 of the first moving part 1 and the second moving part 3 is preset by the remote computer, and the distance a from the working range to the left wall edge, the distance b from the working range to the ground, the width m of the region 30 to be detected, the height n of the region to be detected, and other parameters are also preset. During detection, after the first moving part 1 and the second moving part 3 move for a certain distance along the X-axis direction, the X-ray machine 2 and the detector 4 are controlled to scan from the bottom of the area to be detected 30 to the top of the area to be detected 30 along the Y-axis direction; then, the first moving part 1 and the second moving part 3 move a certain distance along the X-axis direction again, and control the X-ray machine 2 and the detector 4 to scan from the top of the region to be detected 30 to the bottom of the region to be detected 30 along the Y-axis direction, and repeat the steps until the X-ray detection of the region to be detected 30 is completed. In the detection process, each time the first moving part 1 and the second moving part 3 move once, X-ray perspective images are shot once, coordinate information (the lower left corner of the wall body is taken as an original point) of the shot images is transmitted to a remote computer, and the computer can automatically synthesize a plurality of images into a complete large-area perspective view according to the coordinate information. Wherein the single shot area 20 can be of any size without having to scan from the bottom of the wall to the top of the wall or from the left end of the wall to the right end of the wall each time.
As shown in fig. 4, in the above embodiment, it is preferable that the second moving portion 3 is further provided with an auxiliary adjusting portion 9. The auxiliary adjusting part 9 is telescopically moved in a third direction (i.e., Y direction in fig. 3) to adjust the overall center of gravity of the second moving part 3 and the detector 4; wherein the third direction is perpendicular to a plane formed by the first direction and the second direction. Specifically, in this embodiment, the auxiliary adjusting portion 9 includes an expansion link 91 and a support roller 92, the expansion link 91 is installed on the surface of the second moving portion 3 and can move in a Z-axis direction, and the support roller 92 is installed at one end of the expansion link 91 to move in a Z-axis direction along with the expansion link 91. It can be understood that when the telescopic rod 91 extends along the Z-axis direction, the supporting roller 92 is correspondingly supported on the ground, so that the overall center of gravity of the second moving part 3 and the detector 4 is shifted toward the Z-axis direction; on the contrary, when the retractable rod 91 is retracted in the opposite direction of the Z-axis, the overall center of gravity of the second moving part 3 and the detector 4 is shifted in the opposite direction of the Z-axis. Therefore, after the detector 4 moves to a higher position in the Y-axis direction, the instability caused by the shift of the center of gravity can be avoided.
Further, in the above-described embodiment, the first collision avoidance sensor is provided on each of the first moving part 1 and the second moving part 3 so as to prevent the first moving part 1 or the second moving part 3 from moving in the first direction when the first moving part 1 or the second moving part 3 touches an obstacle. Similarly, a second anti-collision sensor is disposed on each of the X-ray device 2 and the detector 4 to prevent the X-ray device 2 or the detector 4 from moving in a second direction when the X-ray device 2 or the detector 4 touches an obstacle. Therefore, when the set area to be detected is too large or the first moving part 1 and the second moving part 3 collide with the bottom, the top and the two side walls of the wall due to mechanical faults, the anti-collision sensor can automatically stop moving, and the use safety of the X-ray detection system is improved.
In the above-described embodiment, preferably, the X-ray detection system further includes an image processing section. The image processing part is connected with the detector 4 to receive the detection data of the detector 4 and perform data processing on the detection data, so that a whole continuous perspective view is obtained, and whether dangerous goods exist in the area 30 to be detected or not is conveniently and accurately judged.
< third embodiment >
On the basis of the second embodiment, the X-ray detection system provided by the third embodiment of the present invention has the following differences: the first main support 7 and the second main support 5 are both receivable.
Specifically, the first main support 7 is mounted on the surface of the first moving part 1 in a reversible manner so as to be switched between an operating state and a storage state; similarly, the second main stand 5 is turnably mounted to a surface of the second moving portion 3 so as to be switched between the operating state and the stored state.
Thus, when it is required to use, the first and second main supports 7 and 5 can be turned over to the state shown in fig. 3, thereby performing X-ray detection. When not in use, the first main support 7 and the second main support 5 can be turned 90 degrees counterclockwise, so that the first main support 7 is horizontally placed on the surface of the first moving part 1, and the second main support 5 is horizontally placed on the surface of the second moving part 3, thereby facilitating transportation and transfer and improving the convenience of use.
It can be understood that the first main support 7 and the second main support 5 can be turned over by the connecting hinge, or can be turned over by the rotating shaft, and the specific connecting structure is not limited, and can be adaptively selected and adjusted as required.
Except for the above structure, the remaining structure of this embodiment is the same as that of the second embodiment, and is not described herein again.
< fourth embodiment >
Fig. 6 shows an X-ray detection method according to a fourth embodiment of the present invention. The method can be realized based on any X-ray detection system, and specifically comprises the following steps of S1-S3:
s1: the first moving part 1 is moved to a first side of the object 10 to be detected, so that the X-ray machine 2 mounted on the first moving part 1 emits X-rays toward the object 10 to be detected.
S2: moving the second moving part 3 to a second side of the article 10 to be detected, so that the detector 4 mounted on the second moving part 3 corresponds to the position of the X-ray machine 2 to receive the X-ray passing through the article 10 to be detected; wherein the first and second sides are opposite sides of the article 10 to be inspected.
