[0003] For security inspection equipment using X-ray technology, the cargo or vehicle being inspected must pass through a channel between the X-ray source and the detector. The beam plane of the radiation emitted by the source must coincide with the radiation receiving surface of the detector. The equipment cabin housing the X-ray source and the arm mounting the detector are separate components, so a baseline is required to guide the equipment layout.

[0038] The following will be combined with the drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is in no way intended to limit the present disclosure and its application or use. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present disclosure.

[0039] As shown in FIGS. 1 to 3, the transmission detection device includes a radiation source 2 and a detector 5 that receives the radiation emitted by the radiation source and penetrating the object 4 to be detected. The transmission detection device further includes a detector boom 6 disposed opposite to the radiation source 2 (hereinafter sometimes simply referred to as boom 6). The detector 5 includes a first detector 51 disposed on the detector boom 6 for receiving the detection radiation emitted by the radiation source 2 and a second detector 52 disposed on the ground between the radiation source 2 and the detector boom 6. Although not shown, a third detector may also be disposed above the detection channel between the radiation source 2 and the detector boom 6, forming a substantially reverse "C" shape with the first detector 51 and the second detector 52.

[0040] A detection channel allowing the object 4 to be detected to pass through is formed between the radiation source 2 and the detector boom 6. During the process of the object 4 to be detected passing through the detection channel, it is scanned by the radiation emitted by the radiation source 2, and the detector 5 receives the radiation penetrating the object to be detected, and the internal condition of the object to be detected is judged by analyzing the radiation received by the detector 5.

[0041] In some embodiments, the object to be detected includes a vehicle or a container.

[0042] In some embodiments, the transmission detection device further includes a radiation source cabin 1 for accommodating and installing the radiation source 2. Optionally, the radiation source cabin 1 is disposed on a transport vehicle. In some optional embodiments, a space for accommodating the detector 5 and the boom 6 is also provided on the transport vehicle. The entire set of radiation detection equipment can be transported and moved by the transport vehicle. After arriving at the working site, the boom 6 is installed opposite to the radiation source 2 to form a detection channel between the boom 6 and the radiation source cabin 1, and then the detector 5 is installed on the boom 6 and / or the ground. In some embodiments, the first detector 51 is always installed in the detector boom 6.

[0043] In some embodiments, the radiation source 2 is installed inside the radiation source cabin 1 when the transmission detection device is working. In some other optional embodiments, the radiation source 2 is installed outside the radiation source cabin 1 when the transmission detection device is working.

[0044] When installing the detector and the detector boom with the detector, it is necessary to position the detector 5 so that it can receive the detection radiation emitted by the radiation source 2. Specifically, it is required that the radiation receiving surface of the detector 5 coincides or substantially coincides with the radiation beam surface emitted by the radiation source 2. Therefore, the present embodiment provides a system for positioning the detector for receiving detection radiation of a transmission detection device, and the system includes a radiation position detection and display unit 8, a visible light emitting component 7, and an adjustment device 9.

[0045] The radiation position detection and display unit 8 is configured to detect and display the position of the radiation beam surface 3 emitted by the radiation source 2 of the transmission detection device, and the projection of the radiation beam surface 3 in the first plane opposite to the radiation emission direction of the radiation source 2 is a straight line.

[0046] The visible light emitting component 7 is configured to emit a visible light beam plane 10 projected as a straight line in a first plane opposite to the radiation emission direction of the radiation source 2 .

[0047] The adjustment device 9 is connected to the visible light emitting component 7 and is configured to adjust the visible light emission direction of the visible light emitting component 7 or the position perpendicular to the visible light beam plane 10 to adjust the visible light beam plane 10 to the position of the ray beam plane 3 displayed by the ray position detection display part 8, so as to arrange or adjust the detector 5 with the visible light beam plane 10 as a reference plane so that the detector 5 can receive the rays emitted by the ray source 2.

[0048] In this embodiment, the radiation position detection and display unit 8 is used to detect and display the position of the radiation beam plane 3 emitted by the radiation source 2. The visible light beam plane 10 emitted by the visible light emitting component 7 is then adjusted by the adjustment device 9 so that the visible light beam plane 10 reaches a position overlapping with the radiation beam plane 3. The operator can then install and position the detector 5 under the guidance of the visible light beam plane 10. The operator can install and position the detector while the radiation source 2 is turned off, thereby improving the operator's safety and also resolving the problem in the prior art of difficulty in aligning the receiving surface of the detector 5 with the radiation beam plane 3 of the radiation source 2.

[0049] There are at least three ray position detection and display units 8, and the projections of at least three of the ray position detection and display units 8 in the visible beam plane 10 are not on the same straight line. Figure 3 shows the situation of three ray position detection and display units 8. Three points that are not on the same straight line determine a plane, and the three ray position detection and display units 8 can determine and display the position of the ray beam plane 3. Therefore, when the visible beam plane 10 is adjusted to simultaneously irradiate the positions of the ray beam planes 3 displayed by the three ray position detection and display units 8, the visible beam plane 10 has reached a position overlapping with the ray beam plane 3. The three ray position detection and display units 8 are configured to respectively detect and display the positions irradiated by the ray beam plane 3 in a direction perpendicular to the visible beam plane 10.

[0050] Referring to Figure 3 , in this embodiment, two radiation position detection and display units 8 are mounted on the ground, and another radiation position detection and display unit 8 is mounted on the arm 6 . These three radiation position detection and display units 8 are arranged in front of the radiation source 2 and configured so that they can all be illuminated by the radiation source 2 . The projections of the three radiation position detection and display units 8 within the visible beam plane 10 are not aligned on the same straight line. Each radiation position detection and display unit 8 displays a position illuminated by the radiation beam plane 3 in the direction of the visible beam plane 10 . The three positions illuminated by the radiation beam plane 3 , as displayed by the three radiation position detection and display units 8 , define a plane.

[0051] Adjustment device 9 is configured to adjust visible beam plane 10 to illuminate the positions of at least three radiation position detection display units 8, respectively displayed by radiation beam plane 3, so as to adjust visible beam plane 10 to a position overlapping with radiation beam plane 3, so that the operator can use visible beam plane 10 as a reference plane to install and position detector 5. Since adjustment device 9 can adjust visible beam plane 10 emitted by visible light emitting component 7, visible light emitting component 7 and adjustment device 9 can be installed near radiation source 2.

[0052] The adjustment device 9 is configured to adjust the position of the visible light emitting component 7 in a direction perpendicular to the visible light beam surface 10, that is, to adjust the position along the length direction of the detection channel, so as to adjust the visible light emitting component 7 to be flush in the length direction of the detection channel (perpendicular to the direction of the visible light beam surface 10).

[0053] Adjustment device 9 is configured to swing the visible light emitting end of visible light emitting component 7 about an axis parallel to a first plane opposite to the radiation emission direction of radiation source 2, thereby adjusting the visible light emission direction of visible light beam plane 10. In this embodiment, the first plane opposite to the radiation emission direction of radiation source 2 is a vertical plane, and the swinging of the visible light emitting end of visible light emitting component 7 about an axis parallel to the first plane opposite to the radiation emission direction of radiation source 2 is also called pitch swinging.

[0054] The adjustment device 9 is configured to swing the visible light emitting end of the visible light emitting component 7 around an axis perpendicular to a first plane opposite to the radiation emission direction of the radiation source 2 to adjust the visible light emission direction of the visible light beam plane 10. In other words, the visible light emitting end of the visible light emitting component 7 swings within a horizontal plane.

[0055] 4 and 5 , the adjustment device 9 includes a base 91, a movable member 92, a first swinging member 93, and a second swinging member 94. The movable member 92 is configured to be movable relative to the base 91 in a direction perpendicular to the visible light beam plane 10 (approximately perpendicular to the paper in FIG. 5 ); the first swinging member 93 is mounted on the movable member 92 so as to move with the movable member 92 relative to the base 91, and is configured to swing relative to the movable member 92 about an axis parallel to a first plane opposite to the radiation emission direction of the radiation source 2.

[0056] The second swinging component 94 is mounted on the first swinging component 93 to swing with the first swinging component 93 relative to the moving component 92. The second swinging component 94 is configured to swing relative to the first swinging component 93 around an axis perpendicular to a first plane opposite to the radiation emission direction of the radiation source 2.

[0057] The visible light emitting component 7 is mounted on a second swinging component 94 so as to swing with the second swinging component 94 about an axis perpendicular to a first plane opposite to the radiation emission direction of the radiation source 2. Furthermore, the visible light emitting component 7 and the second swinging component 94 swing together with the first swinging component 93 about an axis parallel to the first plane opposite to the radiation emission direction of the radiation source 2. The visible light emitting component 7, the first swinging component 93, and the second swinging component 94 are movable together with the movable component 92 in a direction perpendicular to the visible light beam plane 10. In this embodiment, the direction perpendicular to the visible light beam plane 10 is substantially parallel to the first plane opposite to the radiation emission direction of the radiation source 2.

[0058] In some embodiments, the visible light emitting component 7 is configured to emit a visible light beam surface 10 that can illuminate a first plane opposite to the ray emission direction of the ray source 2 and a second plane perpendicular to the above-mentioned first plane and the visible light beam surface 10, and the second plane is located between the first plane and the visible light emitting component 7, so as to install a first detector 51 on the first plane and a second detector 52 on the above-mentioned second plane.

[0059] In this embodiment, the first plane is a vertical plane, and the second plane is a horizontal plane. In this embodiment, the first detector 51 is mounted on the detector arm 6, and the first detector 51 and the second detector 52 are arranged in an L shape.

[0060] In other embodiments, a horizontal cross frame is provided at the upper end of the detector arm 6 vertically arranged opposite to the ray source 2, and the second detector 52 is arranged on the above-mentioned cross frame.

[0061] The radiation position detection display unit 8 includes a scintillator (GOS film) arranged in a direction perpendicular to the visible beam surface 10 and emitting light under the radiation of the radiation, a plurality of photoelectric conversion components arranged in a direction perpendicular to the visible beam surface 10 and converting light signals into electrical signals, and a plurality of indicator lights arranged in a direction perpendicular to the visible beam surface 10. The indicator lights are arranged in a one-to-one correspondence with the photoelectric conversion components, and the indicator lights are configured to be controlled to open and close by the corresponding photoelectric conversion components.

[0062] Among them, the scintillator is a type of material that can emit light after absorbing high-energy particles or rays. When the rays emitted by the ray source 2 radiate onto the scintillator, the scintillator emits light. The photoelectric conversion component converts the light emitted by the scintillator into an electrical signal, which is used to control the corresponding indicator light to display the position of the rays detected by the ray position detection display unit 8.

[0063] In some embodiments, the photoelectric conversion component includes a photodiode; and the indicator light includes an LED light.

[0064] In some embodiments, the visible light emitting component 7 comprises a laser.

[0065] Visible beam plane 10 serves as a reference for positioning detector 5. Visible light emitting component 7 is fixedly connected to adjustment device 9. The position of beam plane 3 is determined by the radiation position detection and display unit 8. The position of visible light emitting component 7 is then adjusted to ensure that visible beam plane 10 is coplanar with beam plane 3. Using visible beam plane 10 as a reference, the position of the detector arm is adjusted to ensure that beam plane 3 coincides with the detector receiving surface.

[0066] According to another aspect of the present disclosure, a method for positioning a system for positioning a detector for receiving detection rays of a transmission detection device is provided. The positioning method includes:

[0067] Arrange at least three radiation position detection and display units 8 in the detection channel between the radiation source 2 and the detector 5, and turn on the radiation source 2 so that the at least three radiation position detection and display units 8 respectively display the positions of the radiation beam plane 3 in the direction perpendicular to the visible beam plane 10;

[0068] Adjusting the visible light emission direction of the visible light emitting component 7 and / or the position along the direction perpendicular to the visible beam plane 10 to adjust the visible beam plane 10 to illuminate at least three positions of the radiation position detection display parts 8 and respectively display the detected radiation beam planes 3;

[0069] When the radiation source 2 is turned off, the detector 5 is arranged or adjusted with the visible light beam plane 10 as a reference plane.

[0070] The specific working steps of the system for positioning the detector receiving the detection radiation of the transmission detection device are as follows:

[0071] 1. Place the radiation position detection and display unit 8 at the detection channel. Typically, the radiation position detection and display unit 8 is placed near the predetermined position of the detector arm 6 and on the nearby channel floor. The radiation position detection and display unit 8 receives the radiation emitted by the radiation source 2 and emits visible light at the indicator light corresponding to the radiation position, marking the position of the radiation position detection and display unit 8 illuminated by the radiation source 3. Visible light continues to exist after the radiation source 2 stops emitting the beam.

[0072] 2. Turn on the visible light emitting unit 7, forming a visible beam plane 10 on the ground opposite the visible light emitting unit 7. Adjust the visible light emitting unit 7 until the visible beam plane 10 coincides with the position where the indicator light on the radiation position detection display unit 8 is illuminated. At this point, the visible beam plane 10 coincides with the beam plane of the radiation source 2, completing the positioning adjustment of the visible light emitting unit 7.

[0073] 3. When setting up the security inspection equipment, the X-ray source 2 does not need to emit a beam. Turn on the visible light emitting component 7. The position of the visible beam plane 10 serves as the reference plane for the arrangement of the detector arm 6. Adjust the position of the detector arm 6 to coincide with the visible beam plane 10. At this point, the X-ray beam plane 3 coincides with the receiving surface of the detector 5.

[0074] 4. When the security inspection equipment requires calibration, the X-ray source 2 does not need to be activated. Turn on the visible light emitting component 7 and observe whether the visible light beam plane 10 is offset from the detector receiving plane 10. If the detector receiving plane is offset from the visible light beam plane 10, adjust the detector arm until the detector receiving plane and visible light beam plane 10 coincide. This completes the calibration.

[0075] The system for positioning a detector for receiving detection rays of a transmission detection device according to this embodiment has the following technical effects:

[0076] 1. The ray beam surface 3 that is invisible to the naked eye is replaced by the visible light beam surface 10 emitted by the visible light emitting component 7, which facilitates the arrangement of the detector arm and the positioning and installation of the detector.

[0077] 2. The ray source 2 can locate the detector of the transmission detection equipment without emitting detection rays, thus avoiding radiation damage to on-site personnel.

[0078] 3. The detector position can be located by turning on the visible light emitting component 7, which is easy to operate.

[0079] 4. The adjustment device 9 can adjust the direction and position of the visible beam plane 10 so that the visible beam plane 10 reaches a position overlapping with the beam plane 3. If the position of the beam plane 3 changes after the replacement or maintenance of the radiation source, the visible beam plane 10 can be adjusted accordingly without affecting the function of the transmission detection equipment.

[0080] 5. When the transmission detection device is in use, turn on the visible light emitting component 7 and observe the relative position change between the detector arm 6 and the visible light beam surface 10 to determine whether the transmission detection device is working normally.

[0081] The above are merely exemplary embodiments of the present disclosure and are not intended to limit the present disclosure. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present disclosure shall be included in the scope of protection of the present disclosure.
