Description

Technical Field

[0001] The present invention relates to the technical field of security inspection, and more specifically, to a security inspection device. Background Art

[0002] The four-source dual-channel dual-viewing security inspection equipment has four radiation sources and two security inspection channels. Each security inspection channel has dual-viewing detection, that is, each security inspection channel has its own side-viewing and top-viewing radiation sources, and the two security inspection channels are completely independent. The radiation source of each security inspection channel will only emit a beam when the security inspection channel detects a package. The logic control is simple and the reliability is greatly improved. At the same time, the beam surface of the top-viewing radiation source only needs to cover the channel, and the installation position can be lowered, which is closer to the inspection package, thereby improving the imaging performance of the equipment.

[0003] Although the four-source dual-channel dual-viewing angle security inspection equipment can realize the independent operation of two security inspection channels, due to the limitation of the security inspection site, the length of the security inspection channel and the distance between the two security inspection channels need to be limited to a certain range. For example, in some airports, the length of the security inspection channel can only be 2 meters, and the distance between the two security inspection channels can only be within 150mm. In order to solve this problem, the existing practice is to use small-pitch detectors, thereby compressing the size of the detectors and the size of the detector box. However, the use of small-sized detectors and detector boxes will greatly increase the cost of security inspection equipment. Summary of the invention

[0004] In order to solve the above problems in the prior art, an embodiment of the present invention provides a small-sized and low-cost security inspection device.

[0040] Reference below Figures 1 to 9 The security inspection device 100 according to the embodiment of the present invention is described.

[0041] like Figures 1 to 9 As shown, the security inspection device 100 according to an embodiment of the present invention includes a first security inspection channel 1, a second security inspection channel 2, two first radiation sources 4, two second radiation sources 5, two first detector groups 6 and two second detector groups 7.

[0042] Combination Figure 1 , Figure 2 and Figure 6 Specifically, the second security inspection channel 2 is separated from the first security inspection channel 1 to form a separation channel 3; two first ray sources 4 are installed in the first security inspection channel 1, and the ray beams of the two first ray sources 4 form a first beam plane 41 and a second beam plane 42 respectively, the first beam plane 41 intersects with at least two adjacent wall surfaces of the first security inspection channel 1 away from the first ray source forming the first beam plane to form a first intersection position, and the second beam plane 42 intersects with at least two other adjacent wall surfaces of the first security inspection channel 1 away from the first ray source forming the second beam plane to form a second intersection position; two second ray sources 5 are installed in the second security inspection channel 2, and the ray beams of the two second ray sources 5 form a third beam plane 51 and a fourth beam plane 52 respectively. The third beam plane 51 intersects with at least two adjacent walls of the second security inspection channel 2 away from the second ray source forming the third beam plane to form a third intersection position, and the fourth beam plane 52 intersects with at least two other adjacent walls of the second security inspection channel 2 away from the second ray source forming the fourth beam plane to form a fourth intersection position; two first detector groups 6 are installed in the first security inspection channel 1, and are respectively located at the first intersection position and the second intersection position; two second detector groups 7 are installed in the second security inspection channel 2, and are respectively located at the third intersection position and the fourth intersection position; wherein, the first detector group 6 located in the interval channel 3 is spaced apart from the second detector group 7 located in the interval channel 3 in the extension direction of the interval channel 3.

[0043] It can be understood that, in the present invention, the first beam surface 41 at least intersects with two adjacent walls of the first security inspection channel 1 away from the first ray source 4 forming the first beam surface 41, and the second beam surface 42 at least intersects with two other adjacent walls of the first security inspection channel 1 away from the first ray source 4 forming the second beam surface 42, so that the ray beams formed by the combination of the two first ray sources 4 can cover the first security inspection channel 1 in the form of tangents in the circumferential direction. As a result, when the inspected object passes through the first security inspection channel 1, the irradiated ray coverage area is larger, and the detection accuracy is higher. In order to cooperate with the two first ray sources 4 and receive the ray signal to complete the detection, it is necessary to A first detector group 6 is respectively arranged at the first intersection position and the second intersection position of the channel 1. The first detector group 6 corresponding to the first beam surface 41 extends along the extension direction of the first intersection position, and the first detector group 6 can cover the intersection line of the two adjacent walls of the first security inspection channel 1 that intersect with the first beam surface 41 and are away from the first ray source 4 that forms the first beam surface 41; the first detector group 6 corresponding to the second beam surface 42 extends along the extension direction of the second intersection position, and the first detector group 6 can cover the intersection line of the two adjacent walls of the first security inspection channel 1 that intersect with the second beam surface 42 and are away from the first ray source 4 that forms the second beam surface 42.

[0044] In the present invention, the third beam plane 51 at least intersects with two adjacent walls of the second security inspection channel 2 away from the second ray source 5 forming the third beam plane 51, and the fourth beam plane 52 at least intersects with two other adjacent walls of the second security inspection channel 2 away from the second ray source 5 forming the fourth beam plane 52, so that the ray beams after the combination of the two second ray sources 5 can cover the second security inspection channel 2 in the form of tangents in the circumferential direction. As a result, when the inspected object passes through the second security inspection channel 2, the irradiated ray coverage area is larger, and the detection accuracy is higher; in order to cooperate with the two second ray sources 5 and receive ray signals to complete the detection, it is necessary to A second detector group 7 is respectively arranged at the third intersection position and the fourth intersection position. The second detector group 7 corresponding to the third beam plane 51 extends along the extension direction of the third intersection position, and the second detector group 7 can cover the intersection line of the two adjacent walls of the second security inspection channel 2 that intersect with the third beam plane 51 and are away from the second ray source 5 that forms the third beam plane 51; the second detector group 7 corresponding to the fourth beam plane 52 extends along the extension direction of the fourth intersection position, and the second detector group 7 can cover the intersection line of the two adjacent walls of the second security inspection channel 2 that intersect with the fourth beam plane 52 and are away from the second ray source 5 that forms the fourth beam plane 52.

[0045] Since the first beam plane 41 intersects at least two adjacent walls of the first security inspection channel 1 away from the first ray source 4 forming the first beam plane 41, and the second beam plane 42 intersects at least two other adjacent walls of the first security inspection channel 1 away from the first ray source 4 forming the second beam plane 42, two first detector groups 6 are installed in the first security inspection channel 1, and are respectively located at the first intersection position and the second intersection position, and the wall of the first security inspection channel 1 adjacent to the second security inspection channel 2 is located in the interval channel 3, so the part of the first detector group 6 will be installed on the wall of the first security inspection channel 1 located in the interval channel 3; Since the third beam plane 51 intersects with at least two adjacent walls of the second security channel 2 away from the second ray source 5 forming the third beam plane 51, and the fourth beam plane 52 intersects with at least two other adjacent walls of the second security channel 2 away from the second ray source 5 forming the fourth beam plane 52, two second detector groups 7 are installed in the second security channel 2 and are respectively located at the third intersection position and the fourth intersection position, and the wall of the second security channel 2 adjacent to the first security channel 1 is located in the interval channel 3, so a part of the second detector group 7 will be installed on the wall of the second security channel 2 located in the interval channel 3.

[0046] According to the security inspection device 100 of the embodiment of the present invention, the first detector group 6 located in the interval channel 3 and the second detector group 7 located in the interval channel 3 are spaced apart in the extension direction of the interval channel 3, so that the width of the interval channel 3 can be reduced, that is, the distance between the first security inspection channel 1 and the second security inspection channel 2 can be reduced, thereby reducing the overall volume of the security inspection device 100 and reducing the occupied space. In addition, in the width direction of the interval channel 3, since it is not necessary to place the first detector group 6 and the second detector group 7 at the same time, the first detector group 6 and / or the second detector group 7 can use larger-sized detectors, which can reduce the number of detectors in the first detector group 6 and / or the second detector group 7, and can reduce the working hours for installing the first detector group 6 and / or the second detector group 7, thereby saving the manufacturing cost of the security inspection device 100.

[0047] In some example scenarios, the distance between the first security inspection channel 1 and the second security inspection channel 2 needs to be controlled within 150 mm. The first detector group 6 located in the interval channel 3 and the second detector group 7 located in the interval channel 3 are spaced apart in the extension direction of the interval channel 3 to meet the requirement that the distance between the first security inspection channel 1 and the second security inspection channel 2 is within 150 mm. In addition, in some old models of security inspection equipment 100, the distance between the two security inspection channels spaced apart is within 150 mm. Setting the distance between the first security inspection channel 1 and the second security inspection channel 2 of the security inspection equipment 100 of the present invention within 150 mm can be compatible with existing old models, facilitating the iterative upgrade of new and old security inspection equipment.

[0048] According to some embodiments of the present invention, Figures 2~5 As shown, the two adjacent wall surfaces at the first intersection position include the side wall surface of the first security inspection channel 1 away from the second security inspection channel 2; the two adjacent wall surfaces at the third intersection position include the side wall surface of the second security inspection channel 2 close to the first security inspection channel 1; the first beam surface 41 and the third beam surface 51 are located in the same plane.

[0049] It can be understood that, since the two adjacent walls at the first intersection position include the side wall of the first security inspection channel 1 away from the second security inspection channel 2, the first detector group 6 receiving the rays of the first beam surface 41 can be set on the side wall of the first security inspection channel 1 away from the second security inspection channel 2 and the top of the first security inspection channel 1; or the first detector group 6 receiving the rays of the first beam surface 41 can be set on the side wall of the first security inspection channel 1 away from the second security inspection channel 2 and the bottom of the first security inspection channel 1. Since the two adjacent walls at the third intersection position include the side wall of the second security inspection channel 2 close to the first security inspection channel 1, the second detector group 7 receiving the rays of the third beam surface 51 can be set on the side wall of the second security inspection channel 2 close to the first security inspection channel 1 and the top of the second security inspection channel 2; or the second detector group 7 receiving the rays of the third beam surface 51 can be set on the side wall of the second security inspection channel 2 close to the first security inspection channel 1 and the bottom of the second security inspection channel 2.

[0050] Therefore, the first detector group 6 receiving the rays of the first beam surface 41 and the second detector group 7 receiving the rays of the third beam surface 51 will not exist in the same plane in the width direction of the spacing channel 3 at the same time. Based on this, compared with the first beam surface 41 and the third beam surface 51 being separated in the extension direction of the spacing channel 3, the first beam surface 41 and the third beam surface 51 are located in the same plane without increasing the distance between the first security inspection channel 1 and the second security inspection channel 2. At the same time, the length of the first security inspection channel 1 and the second security inspection channel 2 can be reduced, so that the volume of the security inspection equipment 100 is further reduced, thereby further reducing the footprint of the security inspection equipment 100 and further reducing the manufacturing cost.

[0051] According to some embodiments of the present invention, Figure 2 As shown, a first ray source 4 forming a first beam surface 41 is installed at the top of the first security inspection channel 1, and one of the first detector groups 6 is installed at the side and bottom of the first security inspection channel 1 away from the second security inspection channel 2; a second ray source 5 forming a third beam surface 51 is installed at the side of the second security inspection channel 2 away from the first security inspection channel 1, and one of the second detector groups 7 is installed at the side and top of the second security inspection channel 2 close to the first security inspection channel 1.

[0052] It can be understood that installing the first ray source 4 at the top of the first security inspection channel 1 can facilitate the first beam surface 41 formed by the first ray source 4 to intersect with the side and bottom of the first security inspection channel 1 away from the second security inspection channel 2 at the same time. As a possible implementation method, the first ray source 4 can be installed on the side of the top of the first security inspection channel 1 close to the second security inspection channel 2. Therefore, a first detector group 6 needs to be installed on the side and bottom of the first security inspection channel 1 away from the second security inspection channel 2, so as to facilitate receiving the signal of the first ray source 4 forming the first beam surface 41.

[0053] The second ray source 5 is installed on the side of the second security inspection channel 2 away from the first security inspection channel 1, so that the third beam plane 51 formed by the second ray source 5 can intersect with the side and top of the second security inspection channel 2 close to the first security inspection channel 1 at the same time. As a possible implementation method, the second ray source 5 can be installed on the lower side of the side of the second security inspection channel 2 away from the first security inspection channel 1. Therefore, a second detector group 7 needs to be installed on the side and top of the second security inspection channel 2 close to the first security inspection channel 1, so as to facilitate receiving the signal of the second ray source 5 forming the third beam plane 51.

[0054] Based on this, it can be easily achieved that the two adjacent wall surfaces intersecting with the first beam surface 41 include the side wall surface of the first security inspection channel 1 away from the second security inspection channel 2; the two adjacent wall surfaces intersecting with the third beam surface 51 include the side wall surface of the second security inspection channel 2 close to the first security inspection channel 1; the first beam surface 41 and the third beam surface 51 are located in the same plane.

[0055] According to some embodiments of the present invention, Figure 3 As shown, a first ray source 4 forming a first beam surface 41 is installed at the top of the first security inspection channel 1, and one of the first detector groups 6 is installed at the side and bottom of the first security inspection channel 1 away from the second security inspection channel 2; a second ray source 5 forming a third beam surface 51 is installed at the side of the second security inspection channel 2 away from the first security inspection channel 1, and one of the second detector groups 7 is installed at the side and bottom of the second security inspection channel 2 close to the first security inspection channel 1.

[0056] It can be understood that installing the first ray source 4 at the top of the first security inspection channel 1 can facilitate the first beam surface 41 formed by the first ray source 4 to intersect with the side and bottom of the first security inspection channel 1 away from the second security inspection channel 2 at the same time. As a possible implementation method, the first ray source 4 can be installed on the side of the top of the first security inspection channel 1 close to the second security inspection channel 2. Therefore, a first detector group 6 needs to be installed on the side and bottom of the first security inspection channel 1 away from the second security inspection channel 2, so as to facilitate receiving the signal of the first ray source 4 forming the first beam surface 41.

[0057] The second ray source 5 is installed on the side of the second security inspection channel 2 away from the first security inspection channel 1, so that the third beam plane 51 formed by the second ray source 5 can intersect with the side and bottom of the second security inspection channel 2 close to the first security inspection channel 1 at the same time. As a possible implementation method, the second ray source 5 can be installed on the upper side of the side of the second security inspection channel 2 away from the first security inspection channel 1. Therefore, a second detector group 7 needs to be installed on the side and bottom of the second security inspection channel 2 close to the first security inspection channel 1, so as to facilitate receiving the signal of the second ray source 5 forming the third beam plane 51.

[0058] Based on this, it can be easily achieved that the two adjacent wall surfaces intersecting with the first beam surface 41 include the side wall surface of the first security inspection channel 1 away from the second security inspection channel 2; the two adjacent wall surfaces intersecting with the third beam surface 51 include the side wall surface of the second security inspection channel 2 close to the first security inspection channel 1; the first beam surface 41 and the third beam surface 51 are located in the same plane.

[0059] According to some embodiments of the present invention, Figure 4 As shown, a first ray source 4 forming a first beam surface 41 is installed at the bottom end of the first security inspection channel 1, and one of the first detector groups 6 is installed on the side and top of the first security inspection channel 1 away from the second security inspection channel 2; a second ray source 5 forming a third beam surface 51 is installed on the side of the second security inspection channel 2 away from the first security inspection channel 1, and one of the second detector groups 7 is installed on the side and top of the second security inspection channel 2 close to the first security inspection channel 1.

[0060] It can be understood that installing the first ray source 4 at the bottom end of the first security inspection channel 1 can facilitate the first beam surface 41 formed by the first ray source 4 to intersect with the side and top of the first security inspection channel 1 away from the second security inspection channel 2 at the same time. As a possible implementation method, the first ray source 4 can be installed on the side of the bottom end of the first security inspection channel 1 close to the second security inspection channel 2. Therefore, a first detector group 6 needs to be installed on the side and top of the first security inspection channel 1 away from the second security inspection channel 2, so as to facilitate receiving the signal of the first ray source 4 forming the first beam surface 41.

[0061] The second ray source 5 is installed on the side of the second security inspection channel 2 away from the first security inspection channel 1, so that the third beam plane 51 formed by the second ray source 5 can intersect with the side and top of the second security inspection channel 2 close to the first security inspection channel 1 at the same time. As a possible implementation method, the second ray source 5 can be installed on the lower side of the side of the second security inspection channel 2 away from the first security inspection channel 1. Therefore, a second detector group 7 needs to be installed on the side and top of the second security inspection channel 2 close to the first security inspection channel 1, so as to facilitate receiving the signal of the second ray source 5 forming the third beam plane 51.

[0062] Based on this, it can be easily achieved that the two adjacent wall surfaces intersecting with the first beam surface 41 include the side wall surface of the first security inspection channel 1 away from the second security inspection channel 2; the two adjacent wall surfaces intersecting with the third beam surface 51 include the side wall surface of the second security inspection channel 2 close to the first security inspection channel 1; the first beam surface 41 and the third beam surface 51 are located in the same plane.

[0063] According to some embodiments of the present invention, Figure 5 As shown, the first ray source 4 forming the first beam surface 41 is installed at the bottom end of the first security inspection channel 1, and one of the first detector groups 6 is installed at the side and top of the first security inspection channel 1 away from the second security inspection channel 2; the second ray source 5 forming the third beam surface 51 is installed at the side of the second security inspection channel 2 away from the first security inspection channel 1, and one of the second detector groups 7 is installed at the side and bottom of the second security inspection channel 2 close to the first security inspection channel 1.

[0064] It can be understood that installing the first ray source 4 at the bottom end of the first security inspection channel 1 can facilitate the first beam surface 41 formed by the first ray source 4 to intersect with the side and top of the first security inspection channel 1 away from the second security inspection channel 2 at the same time. As a possible implementation method, the first ray source 4 can be installed on the side of the bottom end of the first security inspection channel 1 close to the second security inspection channel 2. Therefore, a first detector group 6 needs to be installed on the side and top of the first security inspection channel 1 away from the second security inspection channel 2, so as to facilitate receiving the signal of the first ray source 4 forming the first beam surface 41.

[0065] The second ray source 5 is installed on the side of the second security inspection channel 2 away from the first security inspection channel 1, so that the third beam plane 51 formed by the second ray source 5 can intersect with the side and bottom of the second security inspection channel 2 close to the first security inspection channel 1 at the same time. As a possible implementation method, the second ray source 5 can be installed on the upper side of the side of the second security inspection channel 2 away from the first security inspection channel 1. Therefore, a second detector group 7 needs to be installed on the side and bottom of the second security inspection channel 2 close to the first security inspection channel 1, so as to facilitate receiving the signal of the second ray source 5 forming the third beam plane 51.

[0066] Based on this, it can be easily achieved that the two adjacent wall surfaces intersecting with the first beam surface 41 include the side wall surface of the first security inspection channel 1 away from the second security inspection channel 2; the two adjacent wall surfaces intersecting with the third beam surface 51 include the side wall surface of the second security inspection channel 2 close to the first security inspection channel 1; the first beam surface 41 and the third beam surface 51 are located in the same plane.

[0067] According to some embodiments of the present invention, Figures 6 to 9As shown, the two adjacent wall surfaces at the second intersection position include the side wall surface of the first security inspection channel 1 close to the second security inspection channel 2; the two adjacent wall surfaces at the fourth intersection position include the side wall surface of the second security inspection channel 2 away from the first security inspection channel 1; the second beam surface 42 and the fourth beam surface 52 are located in the same plane.

[0068] It can be understood that, since the two adjacent walls intersecting with the second beam plane 42 include the side wall of the first security inspection channel 1 close to the second security inspection channel 2, the first detector group 6 receiving the rays of the second beam plane 42 can be set on the side wall of the first security inspection channel 1 close to the second security inspection channel 2 and the top of the first security inspection channel 1; or the first detector group 6 receiving the rays of the second beam plane 42 can be set on the side wall of the first security inspection channel 1 close to the second security inspection channel 2 and the bottom of the first security inspection channel 1. Since the two adjacent walls intersecting with the fourth beam plane 52 include the side wall of the second security inspection channel 2 away from the first security inspection channel 1, the second detector group 7 receiving the rays of the fourth beam plane 52 can be set on the side wall of the second security inspection channel 2 away from the first security inspection channel 1 and the top of the second security inspection channel 2; or the second detector group 7 receiving the rays of the fourth beam plane 52 can be set on the side wall of the second security inspection channel 2 away from the first security inspection channel 1 and the bottom of the second security inspection channel 2.

[0069] Therefore, the first detector group 6 receiving the rays of the second beam surface 42 and the second detector group 7 receiving the rays of the fourth beam surface 52 will not exist in the same plane in the width direction of the spacing channel 3 at the same time. Based on this, compared with the second beam surface 42 and the fourth beam surface 52 being separated in the extension direction of the spacing channel 3, the second beam surface 42 and the fourth beam surface 52 are located in the same plane without increasing the distance between the first security inspection channel 1 and the second security inspection channel 2. At the same time, the length of the first security inspection channel 1 and the second security inspection channel 2 can be reduced, so that the volume of the security inspection equipment 100 is further reduced, thereby further reducing the footprint of the security inspection equipment 100 and further reducing the manufacturing cost.

[0070] According to some embodiments of the present invention, Figure 6 As shown, the second ray source 5 forming the fourth beam surface 52 is installed at the top of the second security inspection channel 2, and another second detector group 7 is installed at the side and bottom of the second security inspection channel 2 away from the first security inspection channel 1; the first ray source 4 forming the second beam surface 42 is installed at the side of the first security inspection channel 1 away from the second security inspection channel 2, and another first detector group 6 is installed at the side and top of the first security inspection channel 1 close to the second security inspection channel 2.

[0071] It can be understood that installing the second ray source 5 at the top of the second security inspection channel 2 can facilitate the fourth beam plane 52 formed by the second ray source 5 to intersect with the side and bottom of the second security inspection channel 2 away from the first security inspection channel 1 at the same time. As a possible implementation method, the second ray source 5 can be installed on the side of the top of the second security inspection channel 2 close to the first security inspection channel 1. Therefore, another second detector group 7 needs to be installed on the side and bottom of the second security inspection channel 2 away from the first security inspection channel 1, so as to facilitate receiving the signal of the second ray source 5 forming the fourth beam plane 52.

[0072] Installing the first ray source 4 on the side of the first security inspection channel 1 away from the second security inspection channel 2 can facilitate the second beam surface 42 formed by the first ray source 4 to intersect with the side and top of the first security inspection channel 1 close to the second security inspection channel 2 at the same time. As a possible implementation method, the first ray source 4 can be installed on the lower side of the side of the first security inspection channel 1 away from the second security inspection channel 2. Therefore, another first detector group 6 needs to be installed on the side and top of the first security inspection channel 1 close to the second security inspection channel 2, so as to facilitate receiving the signal of the first ray source 4 forming the second beam surface 42.

[0073] Based on this, it can be easily achieved that the two adjacent wall surfaces intersecting with the second beam surface 42 include the side wall surface of the first security inspection channel 1 close to the second security inspection channel 2; the two adjacent wall surfaces intersecting with the fourth beam surface 52 include the side wall surface of the second security inspection channel 2 away from the first security inspection channel 1; the second beam surface 42 and the fourth beam surface 52 are located in the same plane.

[0075] It can be understood that installing the second ray source 5 at the top of the second security inspection channel 2 can facilitate the fourth beam plane 52 formed by the second ray source 5 to intersect with the side and bottom of the second security inspection channel 2 away from the first security inspection channel 1 at the same time. As a possible implementation method, the second ray source 5 can be installed on the side of the top of the second security inspection channel 2 close to the first security inspection channel 1. Therefore, another second detector group 7 needs to be installed on the side and bottom of the second security inspection channel 2 away from the first security inspection channel 1, so as to facilitate receiving the signal of the second ray source 5 forming the fourth beam plane 52.

[0076] Installing the first ray source 4 on the side of the first security inspection channel 1 away from the second security inspection channel 2 can facilitate the second beam surface 42 formed by the first ray source 4 to intersect with the side and bottom of the first security inspection channel 1 close to the second security inspection channel 2 at the same time. As a possible implementation method, the first ray source 4 can be installed on the upper side of the side of the first security inspection channel 1 away from the second security inspection channel 2. Therefore, another first detector group 6 needs to be installed on the side and bottom of the first security inspection channel 1 close to the second security inspection channel 2, so as to facilitate receiving the signal of the first ray source 4 forming the second beam surface 42.

[0077] Based on this, it can be easily achieved that the two adjacent wall surfaces intersecting with the second beam surface 42 include the side wall surface of the first security inspection channel 1 close to the second security inspection channel 2; the two adjacent wall surfaces intersecting with the fourth beam surface 52 include the side wall surface of the second security inspection channel 2 away from the first security inspection channel 1; the second beam surface 42 and the fourth beam surface 52 are located in the same plane.

[0078] According to some embodiments of the present invention, Figure 8 As shown, the second ray source 5 forming the fourth beam surface 52 is installed at the bottom end of the second security inspection channel 2, and another second detector group 7 is installed on the side and top of the second security inspection channel 2 away from the first security inspection channel 1; the first ray source 4 forming the second beam surface 42 is installed on the side of the first security inspection channel 1 away from the second security inspection channel 2, and another first detector group 6 is installed on the side and top of the first security inspection channel 1 close to the second security inspection channel 2.

[0079] It can be understood that installing the second ray source 5 at the bottom end of the second security inspection channel 2 can facilitate the fourth beam plane 52 formed by the second ray source 5 to intersect with the side and top of the second security inspection channel 2 away from the first security inspection channel 1 at the same time. As a possible implementation method, the second ray source 5 can be installed on the side of the bottom end of the second security inspection channel 2 close to the first security inspection channel 1. Therefore, another second detector group 7 needs to be installed on the side and top of the second security inspection channel 2 away from the first security inspection channel 1, so as to facilitate receiving the signal of the second ray source 5 forming the fourth beam plane 52.

[0080] Installing the first ray source 4 on the side of the first security inspection channel 1 away from the second security inspection channel 2 can facilitate the second beam surface 42 formed by the first ray source 4 to intersect with the side and top of the first security inspection channel 1 close to the second security inspection channel 2 at the same time. As a possible implementation method, the first ray source 4 can be installed on the lower side of the side of the first security inspection channel 1 away from the second security inspection channel 2. Therefore, another first detector group 6 needs to be installed on the side and top of the first security inspection channel 1 close to the second security inspection channel 2, so as to facilitate receiving the signal of the first ray source 4 forming the second beam surface 42.

[0081] Based on this, it can be easily achieved that the two adjacent wall surfaces intersecting with the second beam surface 42 include the side wall surface of the first security inspection channel 1 close to the second security inspection channel 2; the two adjacent wall surfaces intersecting with the fourth beam surface 52 include the side wall surface of the second security inspection channel 2 away from the first security inspection channel 1; the second beam surface 42 and the fourth beam surface 52 are located in the same plane.

[0082] According to some embodiments of the present invention, Fig. 9 As shown, the second ray source 5 forming the fourth beam surface 52 is installed at the bottom end of the second security inspection channel 2, and another second detector group 7 is installed at the side and top of the second security inspection channel 2 away from the first security inspection channel 1; the first ray source 4 forming the second beam surface 42 is installed at the side of the first security inspection channel 1 away from the second security inspection channel 2, and another first detector group 6 is installed at the side and bottom of the first security inspection channel 1 close to the second security inspection channel 2.

[0083] It can be understood that installing the second ray source 5 at the bottom end of the second security inspection channel 2 can facilitate the fourth beam plane 52 formed by the second ray source 5 to intersect with the side and top of the second security inspection channel 2 away from the first security inspection channel 1 at the same time.

Therefore, another second detector group 7 needs to be installed on the side and top of the second security inspection channel 2 away from the first security inspection channel 1, so as to facilitate receiving the signal of the second ray source 5 forming the fourth beam plane 52.

[0084] Installing the first ray source 4 on the side of the first security inspection channel 1 away from the second security inspection channel 2 can facilitate the second beam surface 42 formed by the first ray source 4 to intersect with the side and bottom of the first security inspection channel 1 close to the second security inspection channel 2 at the same time. As a possible implementation method, the first ray source 4 can be installed on the upper side of the side of the first security inspection channel 1 away from the second security inspection channel 2. Therefore, another first detector group 6 needs to be installed on the side and bottom of the first security inspection channel 1 close to the second security inspection channel 2, so as to facilitate receiving the signal of the first ray source 4 forming the second beam surface 42.

[0085] Based on this, it can be easily achieved that the two adjacent wall surfaces intersecting with the second beam surface 42 include the side wall surface of the first security inspection channel 1 close to the second security inspection channel 2; the two adjacent wall surfaces intersecting with the fourth beam surface 52 include the side wall surface of the second security inspection channel 2 away from the first security inspection channel 1; the second beam surface 42 and the fourth beam surface 52 are located in the same plane.

[0086] According to some embodiments of the present invention, the two adjacent walls intersecting the first beam plane 41 include the side wall of the first security inspection channel 1 away from the second security inspection channel 2; the two adjacent walls intersecting the third beam plane 51 include the side wall of the second security inspection channel 2 close to the first security inspection channel 1; the first beam plane 41 and the third beam plane 51 are located in the same plane.

[0087] It can be understood that the first detector group 6 receiving the rays of the first beam surface 41 and the second detector group 7 receiving the rays of the third beam surface 51 will not exist in the same plane in the width direction of the spacing channel 3 at the same time. Based on this, compared with the first beam surface 41 and the third beam surface 51 being separated in the extension direction of the spacing channel 3, the first beam surface 41 and the third beam surface 51 are located in the same plane without increasing the distance between the first security inspection channel 1 and the second security inspection channel 2. At the same time, the length of the first security inspection channel 1 and the second security inspection channel 2 can be reduced, so that the volume of the security inspection equipment 100 is further reduced, thereby further reducing the footprint of the security inspection equipment 100 and further reducing the manufacturing cost.

[0088] At the same time, the first detector group 6 receiving the rays of the second beam surface 42 and the second detector group 7 receiving the rays of the fourth beam surface 52 will not exist in the same plane of the spacing channel 3 in the width direction of the spacing channel 3 at the same time. Based on this, compared with the second beam surface 42 and the fourth beam surface 52 being separated in the extension direction of the spacing channel 3, the second beam surface 42 and the fourth beam surface 52 are located in the same plane without increasing the distance between the first security inspection channel 1 and the second security inspection channel 2.

[0089] According to some embodiments of the present invention, one of the two first detector groups 6 includes m first detectors 61, a portion of the m first detectors 61 is installed on the side of the first security inspection channel 1 away from the second security inspection channel 2, covering the intersection of the first beam surface 41 and the side, another portion of the m first detectors 61 is installed on the top or bottom of the first security inspection channel 1, covering the intersection of the first beam surface 41 and the top or bottom, and m is an integer greater than or equal to 2. The other of the two first detector groups 6 includes n first detectors 61, a portion of the n first detectors 61 is installed on the side of the first security inspection channel 1 close to the second security inspection channel 2, covering the intersection of the second beam surface 42 and the side, another portion of the n first detectors 61 is installed on the bottom or top of the first security inspection channel 1, covering the intersection of the first beam surface 41 and the bottom or top, and n is an integer greater than or equal to 2.

[0090] It should be noted that if Figure 2 and Figure 3 As shown, when a part of the m first detectors 61 are installed on the side of the first security inspection channel 1 away from the second security inspection channel 2, covering the intersection of the first beam surface 41 and the side, another part of the m first detectors 61 can be installed at the bottom of the first security inspection channel 1; at this time, a part of the n first detectors 61 are installed on the side of the first security inspection channel 1 close to the second security inspection channel 2, covering the intersection of the second beam surface 42 and the side, and another part of the n first detectors 61 are installed at the top of the first security inspection channel 1.

[0091] like Figure 4 and Figure 5 As shown, when a part of the m first detectors 61 are installed on the side of the first security inspection channel 1 away from the second security inspection channel 2, covering the intersection of the first beam surface 41 and the side, another part of the m first detectors 61 can be installed at the top of the first security inspection channel 1; at this time, a part of the n first detectors 61 are installed on the side of the first security inspection channel 1 close to the second security inspection channel 2, covering the intersection of the second beam surface 42 and the side, and another part of the n first detectors 61 are installed at the bottom of the first security inspection channel 1.

[0092] Therefore, by arranging m first detectors 61 of one first detector group 6 and n first detectors 61 of another first detector group 6 in the above manner, it can be satisfied that the first beam plane 41 formed by the ray beam of one first ray source 4 intersects with two adjacent wall surfaces of the first security inspection channel 1, and the second beam plane 42 formed by the ray beam of another first ray source 4 intersects with the other two adjacent wall surfaces of the first security inspection channel 1; the two first detector groups 6 are installed in the first security inspection channel 1, and are respectively located at the intersection of the first beam plane 41 and the second beam plane 42.

[0093] According to some embodiments of the present invention, the plurality of first detectors 61 in each first detector group 6 are separately installed in the first security inspection channel 1. This facilitates the installation of each individual first detector 61, and also facilitates the maintenance and repair of each individual first detector 61. When a first detector 61 is damaged, it can be replaced separately without replacing the first detector group 6 as a whole, thus saving maintenance costs.

[0094] Alternatively, the multiple first detectors 61 in each first detector group 6 are integrated and installed as a whole in the first security inspection channel 1. Here, in some environments where it is convenient to install the first detector group 6 integrating multiple first detectors 61, integrating the multiple first detectors 61 and installing them as a whole in the first security inspection channel 1 can save installation time, thereby saving the manufacturing cost of the security inspection device 100.

[0097] like Figure 8 and Fig. 9As shown, when a part of the g second detectors 71 are installed on the side of the second security inspection channel 2 close to the first security inspection channel 1, covering the intersection of the third beam surface 51 and the side, another part of the g second detectors 71 can be installed at the bottom end of the second security inspection channel 2; at this time, a part of the r second detectors 71 are installed on the side of the second security inspection channel 2 away from the first security inspection channel 1, covering the intersection of the fourth beam surface 52 and the side, and another part of the r second detectors 71 are installed at the top of the second security inspection channel 2.

[0098] Therefore, by arranging g second detectors 71 of one second detector group 7 and r second detectors 71 of another second detector group 7 in the above manner, it can be satisfied that the third beam plane 51 formed by the ray beam of one second ray source 5 intersects with two adjacent wall surfaces of the second security inspection channel 2, and the fourth beam planes 52 formed by the ray beam of another second ray source 5 intersect with the other two adjacent wall surfaces of the second security inspection channel 2; the two second detector groups 7 are installed in the second security inspection channel 2, and are respectively located at the intersection of the third beam plane 51 and the fourth beam plane 52.

[0099] According to some embodiments of the present invention, the plurality of second detectors 71 in each second detector group 7 are separately installed in the second security inspection channel 2. This facilitates the installation of each individual second detector 71, and also facilitates the maintenance and repair of each individual second detector 71. When a second detector 71 is damaged, it can be replaced separately without replacing the second detector group 7 as a whole, thus saving maintenance costs.

[0100] Alternatively, the plurality of second detectors 71 in each second detector group 7 are integrated and installed as a whole in the second security inspection channel 2. Here, in some environments where it is convenient to install the second detector group 7 integrating the plurality of second detectors 71, the plurality of second detectors 71 are integrated and installed as a whole in the second security inspection channel 2 to save installation time, thereby saving the manufacturing cost of the security inspection device 100.
