The phrase appearing in various positions in the description does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments.

[0028] In the description of this application, it should be noted that unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "attached" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two components.

[0029] The term "and / or" in this application is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone.

It should be understood that the thickness, length, width and other dimensions of various components shown in the drawings in the embodiments of this application, as well as the overall thickness, length, width and other dimensions of the integrated device are only for illustrative purposes and should not constitute any limitation to this application.

[0031] The existing energy test of X-rays mainly judges the energy of X-rays by artificially setting multiple steel plates in the propagation path of X-rays and measuring the dose rate after X-rays pass through different numbers of steel plates. The steel plates have a certain thickness and are relatively heavy (the weight of one steel plate can reach 10-20 kg). Before each additional steel plate is tested, multiple people are required to cooperate to move the steel plate to the designated position and lock it. The overall structure is very unstable and there are relatively large safety hazards. The X-ray energy test of each accelerator requires multiple layers of steel plates to be stacked. For safety reasons, each time the number of steel plates is adjusted, the accelerator needs to be controlled to stop emitting beams first, and then emit beams again after the number of steel plates is adjusted. The accelerator needs to stop emitting beams and emit beams again multiple times, and the operators need to constantly enter and exit the machine room, which is time-consuming and laborious, and the test efficiency is relatively low.

[0032] In view of this, the embodiments of the present application provide a technical solution, which sets a plurality of ray shielding members capable of moving along a first direction on a vertical support mechanism, so that the ray shielding members can selectively be in a shielding position or a non-shielding position. Moreover, the plurality of ray shielding members are staggered with each other along their thickness directions, and the thickness superposition of the target number of ray shielding members can be realized as needed, without manually carrying the ray shielding members, improving the moving efficiency of the ray shielding members. During the test, ray sources such as accelerators do not need to stop emitting beams, reducing labor costs, reducing safety hazards, shortening the test working hours, and helping to improve the test efficiency of ray energy.

[0033] The ray energy test tooling provided by the embodiments of the present application is applicable to various ray energy test systems, and it can, but is not limited to, test the energy of X-rays.

[0034] Figure 1 is a schematic structural diagram of the ray energy test tooling provided by some embodiments of the present application, Figure 2 is Figure 1 a partial structural schematic diagram of the ray energy test tooling shown, Figure 3 is Figure 1 an exploded view of the structure shown, Figure 4 and Figure 5 are respectively Figure 1 top-view structural schematic diagrams of the structure shown in different states. Referring to Figures 1 to 5 , the ray energy test tooling 100 provided by the embodiments of the present application includes a vertical support mechanism 20 and a plurality of ray shielding members 30. The plurality of ray shielding members 30 are sequentially arranged along the thickness direction Z of the ray shielding members 30. Each ray shielding member 30 is supported on the vertical support mechanism 20 and is movably arranged relative to the vertical support mechanism 20 along a first direction X to selectively be in a shielding position (refer to Figure 5 ) that can shield rays and a non-shielding position (refer to Figure 4), the first direction X, the thickness direction Z, and the vertical direction Y intersect pairwise.

[0035] The vertical support mechanism 20 extends integrally along the vertical direction Y.

[0036] The number of the vertical support mechanisms 20 can be one, or two or more. When the number of the vertical support mechanisms 20 is one, the plurality of ray shielding members 30 are located on one side of the vertical support mechanism 20 along the first direction X. When the number of the vertical support mechanisms 20 is more than two, the adjacent vertical support mechanisms 20 are spaced apart along the first direction X, and a test space is defined between the adjacent vertical support mechanisms 20. The ray shielding member 30 can be located in the test space formed between the adjacent vertical support mechanisms 20 and is movably disposed along the first direction X within the test space.

[0037] The ray shielding member 30 can be suspended on the vertical support mechanism 20 to facilitate movement along the first direction X and reduce the movement resistance.

[0038] When the number of the vertical support mechanisms 20 is more than two, each ray shielding member 30 can be supported by at least one of the adjacent vertical support mechanisms 20. In other words, the ray shielding member 30 can be supported on one of the adjacent vertical support mechanisms 20, or can be supported on two adjacent vertical support mechanisms 20 simultaneously.

[0039] The ray shielding member 30 can be a shielding plate. Exemplarily, the ray shielding member 30 can be a steel plate.

[0040] It can be understood that the thickness directions of the respective ray shielding members 30 are the same, all being the thickness direction Z.

[0041] The plurality of ray shielding members 30 being sequentially spaced apart along the thickness direction Z means that the plurality of ray shielding members 30 are staggered from each other in the thickness direction Z and do not overlap. The adjacent ray shielding members 30 along the thickness direction Z will not interfere or collide during the movement along the first direction X.

[0042] When the ray shielding member 30 is in its shielding position, it can shield rays. When the plurality of ray shielding members 30 are all in the shielding position, the plurality of ray shielding members 30 can be oppositely arranged along the thickness direction Z, and at least a part of the plurality of ray shielding members 30 overlaps in the first direction X so that the total thickness of the shielding members for shielding rays is superimposed.

[0043] Exemplarily, when two ray shielding members 30 are in the shielding position, at least a part of the two ray shielding members 30 overlaps in the first direction X so that both of the two ray shielding members can shield rays.

[0044] When the ray blocker 30 is in the non-blocking position, it only needs to not block the rays. In the first direction X, the non-blocking positions of the ray blockers 30 can be flush with each other or staggered.

[0045] In the embodiment of the present application, a plurality of ray blockers 30 capable of moving along the first direction X are arranged on the vertical support mechanism 20, so that the ray blockers 30 can be selectively in the blocking position or the non-blocking position. Moreover, the plurality of ray blockers 30 are sequentially spaced apart and staggered from each other along their thickness direction Z, and the thickness superposition of the target number of ray blockers 30 can be realized as needed, without manual handling of the ray blockers 30, improving the moving efficiency of the ray blockers 30. During the test process, ray sources such as accelerators do not need to stop the beam, reducing labor costs, reducing potential safety hazards, shortening the test working hours, and helping to improve the test efficiency of the ray energy.

[0046] In some embodiments, referring to Figures 1 to 3 , the ray energy test tooling 100 further includes a plurality of independent driving mechanisms 40, and the plurality of driving mechanisms 40 are connected to the plurality of ray blockers 30 in a one-to-one correspondence to respectively drive the plurality of ray blockers 30 to move along the first direction X.

[0047] The driving mechanism 40 can be arranged on the vertical support mechanism 20 for connection with the ray blocker 30.

[0048] The driving mechanism 40 can be a cylinder driving mechanism, a motor driving mechanism or other suitable types of driving mechanisms.

[0049] In the embodiment of the present application, the ray blocker 30 is driven to move by the driving mechanism 40, which is conducive to realizing the automatic adjustment and control of the position of the ray blocker 30. The plurality of independent driving mechanisms 40 are connected to the plurality of ray blockers 30 in a one-to-one correspondence, and can drive the plurality of ray blockers 30 to move independently of each other along the first direction X, facilitating the flexible selection of the number of ray blockers 30 in the blocking position.

[0050] In some embodiments, referring to Figure 3 , the driving mechanism 40 includes a cylinder 41 and a telescopic rod 42. The cylinder 41 is fixedly arranged on the outer side of the vertical support mechanism 20 along the first direction X away from the ray blocker 30, the telescopic rod 42 is connected to the cylinder 41, and is telescopically arranged relative to the cylinder 41 along the first direction X. The vertical support mechanism 20 includes a first through hole 21, and the telescopic rod 42 passes through the first through hole 21 and is fixedly connected to the ray blocker 30.

[0051] The side of the vertical support mechanism 20 facing the ray blocker 30 along the first direction X is the inner side of the vertical support mechanism 20, and the side away from the ray blocker 30 along the first direction X is the outer side of the vertical support mechanism 20. The test space is formed on the inner side of the vertical support mechanism 20.

[0052] The cylinder 41 is arranged outside the vertical support mechanism 20, which will not occupy the inner space of the vertical support mechanism 20 and will not affect the test results.

[0053] The cylinder 41 and the vertical support mechanism 20 can be fixedly connected by means of screw connection, welding, riveting, snap connection or other suitable methods.

[0054] The telescopic rod 42 and the ray shielding member 30 can be fixedly connected by means of screw connection, welding, riveting, snap connection or other suitable methods.

[0055] The diameter of the first through hole 21 can be larger than the outer diameter of the telescopic rod 42, which is convenient for the hole wall of the first through hole 21 to contact during the telescopic process of the telescopic rod 42, improving the smoothness of the telescopic movement of the telescopic rod 42.

[0056] When the telescopic rod 42 extends out of the cylinder 41, the ray shielding member 30 fixedly connected to the telescopic rod 42 can be switched to the shielding position; when the telescopic rod 42 retracts into the cylinder 41, the ray shielding member 30 fixedly connected to the telescopic rod 42 can be switched to the non-shielding position. By controlling the telescopic distance of the cylinder, the position of the ray shielding member 30 can be accurately controlled.

[0057] In the embodiment of the present application, the cylinder 41 drives the telescopic rod 42 to expand and contract, thereby driving the ray shielding member 30 to move. The structure is simple and the driving process is easy to control, which is beneficial to improving the position accuracy of the ray shielding member 30 and thus improving the test accuracy.

[0058] In some embodiments, the ray energy test tooling 100 further includes a plurality of limiting components, and the plurality of limiting components are arranged in one-to-one correspondence with the plurality of ray shielding members 30, and each limiting component is configured to limit the maximum distance of the ray shielding member 30 moving along the first direction X.

[0059] Each limiting component may include two limit members, and the two limit members respectively generate corresponding indication signals after the ray shielding member 30 moves to the farthest positions on the opposite sides in the first direction X, so as to indicate the driving mechanism 40 to stop driving the ray shielding member 30 to continue moving.

[0060] Exemplarily, one of the limit members can generate an indication signal after the ray shielding member 30 moves to the shielding position, and the other limit member can generate an indication signal after the ray shielding member 30 moves to the non-shielding position.

[0061] The limiting component may include structures such as a limit switch and a limit sensor. The limit switch may be a magnetic switch, for example, and the limit sensor may be an infrared sensor, for example.

[0062] In the embodiments of the present application, by providing a limiting component, the position adjustment accuracy of the ray shielding member 30 can be further improved, and problems such as test errors caused by the failure of the driving mechanism 40 or collisions between structural members can be reduced.

[0063] In some embodiments, the ray energy test tooling 100 further includes a plurality of guide rods 51. Each guide rod 51 extends along the first direction X and is fixedly connected to a corresponding ray shielding member 30. Each guide rod 51 passes through the vertical support mechanism 20 and is movably arranged relative to the vertical support mechanism 20 along the first direction X.

[0064] The vertical support mechanism 20 is provided with a second through hole 22, and the guide rod 51 is inserted into the second through hole 22.

[0065] The guide rod 51 can be fixedly connected to the ray shielding member 30 by means of screw connection, welding, riveting, clamping or other suitable methods.

[0066] Each guide rod 51 can be connected to the vertical support mechanism 20 through a linear bearing 52, so that the movement of the guide rod 51 is smoother and more unobstructed. The linear bearing 52 can be arranged outside the vertical support mechanism 20.

[0067] The driving mechanism 40 and the guide rod 51 connected to the same ray shielding member 30 can be connected to the same vertical support mechanism 20.

[0068] The corresponding relationship between the guide rod 51 and the ray shielding member 30 can be one-to-one or many-to-one.

[0069] In some examples, the number of guide rods 51 can be the same as the number of ray shielding members 30, and the multiple guide rods 51 are connected to the multiple ray shielding members 30 in a one-to-one correspondence.

[0070] In other examples, the number of guide rods 51 can also be more than the number of ray shielding members 30, and at least some of the ray shielding members 30 are correspondingly connected to more than two guide rods 51.

[0071] The guide rod 51 can assist in supporting the ray shielding member 30 and improve the support stability of the ray shielding member 30. Moreover, the guide rod 51 can also guide the movement of the ray shielding member 30, reducing the possibility of the ray shielding member 30 getting stuck or jammed.

[0072] In some embodiments, each ray shielding member 30 is fixedly connected to two guide rods 51, and the two guide rods 51 are connected to the same end of the ray shielding member 30 along the first direction X.

[0073] The two guide rods 51 can be slidably connected to the same vertical support mechanism 20, and the non-shielding position of the ray shielding member 30 can be adjacent to the vertical support mechanism 20.

[0074] Two guide rods 51 can be connected to the upper and lower parts of the ray shielding member 30 so that the support and guidance of the ray shielding member 30 are more balanced.

[0075] Furthermore, both of the two guide rods 51 and the telescopic rod 42 are connected to the same end of the ray shielding member 30 along the first direction X.

[0076] The guide rods 51 and the telescopic rod 42 can be vertically spaced apart and respectively connected to different positions of the ray shielding member 30 in the vertical direction, thereby improving the support balance. When the number of the guide rods 51 is two, the telescopic rod 42 can be located between the two guide rods 51 to minimize the downward effect of the ray shielding member 30 on the telescopic rod 42 as much as possible, thereby reducing the driving resistance.

[0077] The two guide rods 51 are connected to the same end of the ray shielding member 30 along the first direction X. When the ray shielding member 30 is in the non-shielding position, the guide rods 51 do not block the rays, improving the accuracy of the test results.

[0078] In some embodiments, referring to Figure 4 and Figure 5 , the number of the vertical support mechanisms 20 is more than two. A plurality of ray shielding members 30 are located between two adjacent vertical support mechanisms 20 and are alternately supported by the two adjacent vertical support mechanisms 20 in the thickness direction Z.

[0079] In other words, each ray shielding member 30 is supported by one of the adjacent vertical support mechanisms 20, and any two adjacent ray shielding members 30 in the thickness direction Z are respectively supported by two adjacent vertical support mechanisms 20.

[0080] The non-shielding position of the ray shielding member 30 can be adjacent to the vertical support mechanism 20 for supporting the ray shielding member 30. The shielding position of the ray shielding member 30 can be at the middle position of two adjacent vertical support mechanisms 20 along the first direction X.

[0081] The inventor recognized that if the ray shielding member 30 is supported by two vertical support mechanisms 20, when the ray shielding member 30 is in the non-shielding position, the connection structure between the ray shielding member 30 and one of the vertical support mechanisms 20 may block the rays, affecting the test accuracy of the ray energy.

[0082] Therefore, in the embodiments of the present application, each ray shielding member 30 is supported by one of the adjacent vertical support mechanisms 20, and only a connection support structure needs to be provided between the ray shielding member 30 and one of the vertical support mechanisms 20, reducing the shielding phenomenon of the rays caused by other structures in the test space and improving the test accuracy.

[0083] A plurality of ray shielding members 30 are alternately supported on two adjacent vertical support mechanisms 20 in the thickness direction Z. On the one hand, the weight of the plurality of ray shielding members 30 can act on the two vertical support mechanisms 20 relatively evenly, reducing the load-bearing and burden of a single vertical support mechanism 20. On the other hand, it can also reduce the layout density of structures such as the drive mechanism, connection mechanism, and guiding mechanism of the ray shielding member 30, and reduce the assembly difficulty.

[0084] In some embodiments, referring to Figures 1 to 3 , the ray energy test tooling 100 further includes a reinforcing rod 53 extending along the first direction X, and both ends of the reinforcing rod 53 are respectively connected to adjacent vertical support mechanisms 20.

[0085] Optionally, both ends of the reinforcing rod 53 can be respectively connected to the vertical ends of adjacent vertical support mechanisms 20, so that the reinforcing rod 53 deviates from the shielding position of the ray shielding member 30, reducing the influence of the reinforcing rod 53 on the test results.

[0086] The ray energy test tooling 100 further includes a horizontal support mechanism 10, and the vertical support mechanism 20 is provided on one side of the horizontal support mechanism 10 in the vertical direction. Optionally, the vertical support mechanism 20 can be provided on the upper side of the horizontal support mechanism 10. The horizontal support mechanism 10 can improve the support stability.

[0087] The reinforcing rod 53 can be connected to the vertical ends of adjacent vertical support mechanisms 20 that deviate from the horizontal support mechanism 10 to maximize the support strength.

[0088] The reinforcing rod 53 and the vertical support mechanism 20 can be connected together by welding, screw connection, riveting or other suitable methods.

[0089] In the embodiment of the present application, by providing the reinforcing rod 53 between adjacent vertical support mechanisms 20, the structural strength and support stability of the vertical support mechanism 20 can be improved.

[0090] In some embodiments, the ray energy test tooling 100 further includes a horizontal support mechanism 10, and the vertical support mechanism 20 is provided on one side of the horizontal support mechanism 10 in the vertical direction. The horizontal support mechanism 10 includes a support plate 11, and a weight reduction structure 111 is provided on the support plate 11, and the weight reduction structure 111 penetrates through the support plate 11 along the thickness direction of the support plate 11.

[0091] The thickness direction of the support plate 11 can be the vertical direction Y.

[0092] The vertical support mechanism 20 can be provided on the upper side of the horizontal support mechanism 10. At this time, the horizontal support mechanism 10 can form the support base of the ray energy test tooling 100.

[0093] The weight-reducing structure 111 can be a through-hole, a through-groove or other through structures. The shape of the weight-reducing structure 111 can be a regular shape such as a circle, an ellipse, a square, a triangle, etc., or an irregular shape.

[0094] The number of the weight-reducing structures 111 can be multiple, and the multiple weight-reducing structures 111 can be evenly spaced to make the weight distribution of the support plate 11 more balanced.

[0095] In the embodiment of the present application, the support stability can be improved by setting the lateral support mechanism 10. The weight-reducing structure 111 on the support plate 11 can reduce the weight and facilitate the flexible adjustment of the position of the ray energy test tooling 100.

[0096] In some embodiments, referring to Figures 1 to 3 , the ray energy test tooling 100 further includes a lateral support mechanism 10, and a vertical support mechanism 20 is arranged on one side of the lateral support mechanism 10 along the vertical direction. The lateral support mechanism 10 includes a support plate 11, and at least one of the two opposite sides of the support plate 11 in the thickness direction Z is provided with an avoidance notch 112. The avoidance notch 112 is recessed inward along the thickness direction Z of the support plate 11 and penetrates through the support plate 11 along the thickness direction of the support plate 11.

[0097] It should be noted that the thickness direction Z is the thickness direction of the ray shielding member 30. The thickness direction of the support plate 11 intersects with the thickness direction of the ray shielding member 30, and the thickness direction of the support plate 11 can be the vertical direction Y.

[0098] The avoidance notch 112 can be formed by a groove structure, and the groove is recessed from the edge of the support plate 11 in the thickness direction Z toward the inside of the support plate 11.

[0099] It can be understood that the ray to be tested passes through the ray shielding member 30 in the thickness direction Z. The ray source for emitting rays is arranged on one side of the ray energy test tooling 100 in the thickness direction Z, and the dosimeter for collecting the ray dose rate is arranged on the other side of the ray energy test tooling 100 in the thickness direction Z. The rays emitted by the ray source are usually fan-shaped. When the arrangement position of the ray source is relatively low, the edge of the support plate 11 may block some rays.

[0100] Therefore, in the embodiment of the present application, at least one side of the support plate 11 in the thickness direction Z is provided with the avoidance notch 112. By avoiding the rays through the avoidance notch 112, the possibility of the support plate 11 blocking the rays is reduced, and the test accuracy is further improved.

[0101] Optionally, one of the two opposite sides of the support plate 11 in the thickness direction Z is provided with the avoidance notch 112, and the avoidance notch 112 can be arranged on the side of the support plate 11 facing the ray source in the thickness direction Z.

[0102] Optionally, avoidance notches 112 are provided on both sides of the support plate 11 oppositely arranged in the thickness direction Z. Any side of the ray energy test tooling 100 can face the ray source, improving the flexibility of the position arrangement of the ray energy test tooling 100.

[0103] In some embodiments, referring to Figure 1 , the lateral support mechanism 10 further includes a support frame 12. The support plate 11 is arranged on the upper side of the support frame 12 in the vertical direction. Travel wheels 13 are provided on the lower side of the support frame 12 in the vertical direction. The position of the ray energy test tooling 100 can be flexibly moved through the travel wheels 13.

[0104] The support frame 12 can support the vertical support mechanism 20 at a certain height, facilitating the arrangement of structures such as the ray source and the dosimeter. At the same time, a relatively large accommodation space is formed in the area of the support frame 12 below the support plate 11, facilitating the accommodation of devices such as the control device and the air pump.

[0105] In some embodiments, referring to Figure 3 , the vertical support mechanism 20 includes a vertical support plate 23 and two reinforcing plates 24. The vertical support plates 23 of adjacent vertical support mechanisms 20 are arranged oppositely in the first direction X. The first through hole 21 and the second through hole 22 are both opened on the vertical support plate 23. The two reinforcing plates 24 are arranged oppositely in the thickness direction Z and are respectively connected to the two sides of the vertical support plate 23 oppositely arranged in the thickness direction Z. The reinforcing plates 24 can improve the support stability of the vertical support plate 23 and the connection stability between the vertical support plate 23 and the support plate 11.

[0106] In some embodiments, the ray shielding member 30 includes a steel plate body 31 and a chromium layer 32 coated on the outer side of the steel plate body 31. The chromium layer 32 has high wear resistance and anti-rust functions, which can make the outer surface of the ray shielding member 30 smoother, so that multiple ray shielding members 30 are stacked more in place in the thickness direction Z, reducing the test error and further improving the test accuracy.

[0107] The control method of the ray energy test tooling provided in any embodiment of the present application includes:

[0108] In response to the received first indication signal, controlling a corresponding ray shielding member 30 to move to the shielding position in the first direction X, where the first indication signal is used to indicate that the corresponding ray shielding member 30 shields the ray; and / or

[0109] In response to the received second indication signal, controlling a corresponding ray shielding member 30 to move to the non-shielding position in the first direction X, where the second indication signal is used to indicate that the corresponding ray shielding member 30 does not shield the ray.

[0110] It is understandable that both the first indication signal and the second indication signal contain information about the corresponding ray shielding member 30. Exemplarily, the ray energy testing tooling 100 may include n ray shielding members sequentially distributed along the thickness direction Z. Both the first indication signal and the second indication signal contain information about the i-th ray shielding member 30, where i may be 1, 2, 3... or n. That is, the first indication signal can be used to indicate that the i-th ray shielding member 30 shields the ray, and the second indication signal can be used to indicate that the i-th ray shielding member 30 does not shield the ray.

[0111] When the ray energy testing tooling 100 receives the first indication signal, it controls the i-th ray shielding member 30 to move to the shielding position; when the ray energy testing tooling 100 receives the second indication signal, it controls the i-th ray shielding member 30 to move to the non-shielding position.

[0112] The ray energy testing tooling 100 may include a main control device 60, and the main control device 60 is connected to the driving mechanisms 40 of the respective ray shielding members 30. The main control device 60 is used to receive the first indication signal and the second indication signal, and controls the driving mechanism 40 to generate corresponding actions according to the first indication signal and the second indication signal it receives, so as to drive the ray shielding member 30 to switch between the shielding position and the non-shielding position.

[0113] The driving mechanism 40 may be a cylinder-type driving mechanism. At this time, the ray energy testing tooling 100 may further include an air pump, and the main control device 60 is connected to the respective driving mechanisms 40 through the air pump, so as to drive the telescopic rods 42 of the respective driving mechanisms 40 to generate telescopic actions through the air pump.

[0114] Both the main control device 60 and the driving mechanism 40 can be arranged on the support frame 12, and the structure is more compact, and the ray energy testing tooling 100 can be flexibly moved as a whole.

[0115] According to the second aspect of the present application, the embodiments of the present application further provide a ray energy testing system 1000. Figure 6 It is a schematic structural diagram of a ray energy testing system provided by some embodiments of the present application. Refer to Figure 6 The ray energy testing system 1000 provided by the embodiments of the present application includes a ray energy testing tooling 100, a ray source 200, and a dosimeter 300 according to any embodiment of the present application. The ray source 200 is arranged on one side of the ray energy testing tooling 100 along the thickness direction Z to emit rays to the ray energy testing tooling 100. The dosimeter 300 is arranged on the side of the ray energy testing tooling 100 facing away from the ray source 200 to obtain the dose rate data of the rays passing through the ray energy testing tooling 100.

[0116] The ray source 200 may be, but is not limited to, an accelerator.

[0117] The rays emitted by the ray source 200 can be, but are not limited to, X-rays.

[0118] The ray source 200 and the dosimeter 300 can be set independently of the ray energy test tooling 100, or can be connected to the ray energy test tooling 100 through a connection structure. For example, they can be connected to the support frame 12.

[0119] The ray source 200, the ray energy test tooling 100, and the dosimeter 300 can be arranged at intervals along the thickness direction Z.

[0120] In some embodiments, the ray energy test system 1000 may further include a display device, which is used to display information such as the number of ray blockers 30 in the occlusion position, the total thickness of the ray blockers 30 in the occlusion position, and the dose rate data collected by the dosimeter 300 each time.

[0121] According to the fourth aspect of the present application, embodiments of the present application further provide a test method for the ray energy test system 1000 provided in any embodiment of the present application.

[0122] Figure 7 is a schematic flowchart of the test method of the ray energy test system provided in some embodiments of the present application. Refer to Figure 7 , the test method of the ray energy test system 1000 provided in the embodiments of the present application includes:

[0123] Step S10, respectively obtain the dose rate data collected by the dosimeter 300 in the state where all the ray blockers 30 are in the non-occlusion position and in the state where at least some of the multiple ray blockers 30 are in the occlusion position; and

[0124] Step S20, determine the energy of the ray according to the dose rate data obtained multiple times.

[0125] In step S10, the dosimeter 300 collects the dose rate data respectively when all the ray blockers 30 are in the non-occlusion position, when only one ray blocker 30 is in the occlusion position, when only two ray blockers 30 are in the occlusion position... and when all the ray blockers 30 are in the occlusion position. When the ray energy test tooling 100 includes n ray blockers 30, in step S10, the dosimeter 300 obtains n + 1 dose rate data.

[0126] When a ray penetrates a substance, its intensity will attenuate. When different numbers of ray blockers 30 block the ray, the attenuation degree of the ray is different. The attenuation law of the ray follows the following formula:

[0127]

[0128] In the above formula, d is the thickness of the ray shielding member 30 penetrated by the ray, with the unit of millimeter (mm); is the dose rate value measured when there is no material shielding, with the unit of gray per minute (Gy / min); is the dose rate value measured when the penetrated material thickness is d, with the unit of gray per minute (Gy / min); μ is the attenuation coefficient, with the unit of per millimeter (mm -1 ). Among them and The values of both can be measured by the dosimeter 300.

[0129] Assume that the number of ray shielding members 30 is 5, and the ray shielding member 30 is a steel plate with a density of 7.85×10 3 kg / m 3 , and its thickness is 25 mm. The probe of the dosimeter 300 is equipped with a balance body and is placed at a target point 1 m away from the radiation source at a distance of 200 on the central axis in the 0° direction of the radiation beam. Use the radiation energy test system 1000 provided by any embodiment of the present application to test the radiation energy, and a total of 6 groups of data are recorded as follows in the table:

[0130] Table 1. Radiation dose rate values corresponding to different steel plate thicknesses

[0131]

[0132] Among them, are all dose rate values measured by the dosimeter 300. According to the data measured in the above table, μ can be obtained by fitting using the least squares method, and then the half-value layer of the ray can be obtained. Furthermore, the energy of the ray can be obtained according to the energy curve corresponding to the half-value layer. Since the acquisition of the half-value layer and the obtaining of the energy of the ray based on the half-value layer are technologies easily known to those skilled in the art, therefore, it will not be elaborated here.

[0133] In some embodiments, the test method of the radiation energy test system 1000 further includes:

[0134] In response to the first trigger signal, send a first indication signal to the radiation energy test tooling 100 to control a corresponding ray shielding member 30 to move to the shielding position along the first direction X; and / or

[0135] In response to the second trigger signal, send a second indication signal to the radiation energy test tooling 100 to control a corresponding ray shielding member 30 to move to the non-shielding position along the first direction X.

[0136] After the ray energy test tooling 100 receives the first indication signal, it controls a corresponding ray shielding member 30 to move along the first direction X to the shielding position to shield the ray. After the ray energy test tooling 100 receives the second indication signal, it controls a corresponding ray shielding member 30 to move along the first direction X to the non-shielding position to avoid shielding the ray.

[0137] As an example, the ray energy test system 1000 may include a plurality of trigger buttons corresponding to the plurality of ray shielding members 30. The trigger button may be a physical button structure or a virtual button on the control interface. The first trigger signal and the second trigger signal may be generated after the trigger button is triggered or when the trigger button is in a specific state.

[0138] As another example, the first trigger signal and the second trigger signal may also be automatically generated when a set condition is met. The set condition may be, for example, that the duration reaches a preset duration.

[0139] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application, and they should all be covered by the scope of the claims and the description of the present application.
