The sensor integrated board has multiple sensor devices, which can be used independently. When using the camera, the radiation-resistant shielding device shields the sensor devices on the sensor integrated board and controls one sensor device to be exposed, receiving image information. During use in high-radiation environments, the camera periodically performs health checks on the pixels of this sensor device (e.g., detecting noise levels or pixel failure rates through test signals). When the damage level of the current sensor device exceeds a preset threshold (e.g., the percentage of failed pixels exceeds 5%), the shielding control device controls the radiation-resistant shielding device to expose other healthy sensor devices and controls those healthy sensor devices to operate. In this embodiment, the automatic sensor device switching mechanism significantly improves the camera's fault tolerance; even if some sensor devices are damaged, the camera can continue to operate normally, thereby extending the overall lifespan of the camera.

[0045] Nuclear radiation environments (such as nuclear power plants, nuclear waste disposal facilities, or deep space exploration) place extremely high demands on imaging equipment. In these environments, sensors in traditional cameras can be rapidly damaged by radiation from high-energy particles (such as gamma rays and neutrons), leading to pixel damage, increased noise, or complete failure, thereby affecting image quality.

[0046] To address the technical problem that traditional camera sensors are rapidly damaged by high-energy particles (such as gamma rays and neutrons) in nuclear radiation environments, leading to pixel damage, increased noise, or complete failure, this application provides an area-automatic selection radiation-resistant camera. Multiple sensor devices 11 on the sensor integration board 10 are shielded or exposed by an anti-radiation shielding device 20 controlled by a shielding control device 30. This allows for switching of damaged sensor devices 11 or shielding protection of normal sensor devices 11, thereby extending the overall lifespan of the camera.

[0047] Please refer to Figure 1 , Figure 1 This application provides a schematic diagram of the structure of an automatic area selection radiation-resistant camera.

[0048] like Figure 1-2 As shown, the camera includes a sensor integration board 10, an anti-radiation shielding device 20, and a shielding control device 30. The sensor integration board 10 is equipped with multiple sensor devices 11. The anti-radiation shielding device 20 is located on one side of the receiving end of the sensor device 11 and is used to shield the sensor device 11 and protect the shielded sensor device 11 from radiation. The shielding control device 30 controls the anti-radiation shielding device 20 to shield or expose the sensor device 11, so as to switch the damaged sensor device 11 or shield and protect the normal sensor device 11, thereby achieving the technical effect of extending the overall life of the camera.

[0049] For example, in this embodiment, the sensor devices 11 on the sensor integration board 10 can be used independently. When using the camera, the anti-radiation shielding device 20 shields the sensor devices 11 on the sensor integration board 10 and controls the anti-radiation shielding device 20 to expose one of the sensor devices 11 and control that sensor device 11 to receive image information. During the use of the camera in a high-radiation environment, the pixels of the sensor device 11 are periodically checked for health (e.g., by detecting noise level or pixel failure rate through test signals). When the damage level of the current sensor device 11 is detected to exceed a preset threshold (e.g., the proportion of failed pixels exceeds 5%), the shielding control device 30 controls the anti-radiation shielding device 20 to expose other healthy sensor devices 11 and controls the healthy sensor devices 11 to work. In this embodiment, the automatic switching mechanism of the sensor devices 11 significantly improves the fault tolerance of the camera. Even if some sensor devices 11 are damaged, the camera can continue to operate normally, thereby extending the overall lifespan of the camera.

[0050] In some embodiments, such as Figure 2As shown, multiple sensor devices 11 are arranged in an array on the sensor integration board 10, making the sensor distribution on the sensor integration board 10 more dense, thereby reducing the size of the camera.

[0051] In some embodiments, such as Figure 3 As shown, the anti-radiation shielding device 20 includes a fixing frame 21 and a shielding plate 22. The fixing frame 21 is disposed on one side of the receiving end of the sensor device 11. The fixing frame 21 is provided with a window 24, and the window 24 is correspondingly disposed to the sensor device 11. The shielding plate 22 is disposed inside the window 24 and is connected to the shielding control device 30. The shielding control device 30 controls the opening and closing of the window 24 through the shielding plate 22. It can be understood that, in this embodiment, the shielding control device 30 removes the shielding plate 22 from the window 24 or places the shielding plate 22 inside the window 24 to achieve shielding or exposure of the sensor device 11. This not only enables automatic switching of the sensor device 11, but also controls the opening and closing of the window 24 by picking up or placing the shielding plate 22. This allows the shielding control device 30 to control the shielding plate 22 in a small activity space, which can further reduce the size of the camera.

[0052] In some embodiments, the shield 22 is made of tungsten metal, which can shield high-frequency ionizing radiation gamma rays, thereby protecting the sensor device 11 in a high-radiation environment.

[0053] In some embodiments, such as Figure 3 As shown, the blocking control device 30 includes a first drive slide rail 31, a second drive slide rail 32, and a robotic arm 33 for gripping the blocking plate 22. The second drive slide rail 32 is disposed at the drive end of the first drive slide rail 31, and the robotic arm 33 is disposed at the drive end of the second drive slide rail 32. The first drive slide rail 31 is used to drive the robotic arm 33 to move along a first direction, and the second drive slide rail 32 is used to drive the robotic arm 33 to move along a second direction. The first direction is perpendicular to the second direction. It can be understood that, in the embodiment, the robotic arm 33 can achieve arbitrary movement in a two-dimensional direction under the combined action of the first drive slide rail 31 and the second drive slide rail 32, thereby enabling the robotic arm 33 to accurately grip or place the blocking plate 22.

[0054] In some embodiments, such as Figure 4-5As shown, the robotic arm 33 includes a telescopic motor 331, a rotary motor 332, and a first latching member 333. The rotary motor 332, the telescopic motor 331, and the first latching member 333 are sequentially arranged at the drive end of the second drive slide rail 32. The baffle plate 22 is provided with a first slot 23 adapted to the first latching member 333. The telescopic motor 331 drives the first latching member 333 to extend into the first slot 23, and the rotary motor 332 drives the first latching member 333 to rotate and latch with the first slot 23. In this embodiment, when the robotic arm 33 needs to grasp the baffle plate 22, At time 2, the first locking member 333 is driven by the first drive slide rail 31 and the second drive slide rail 32 to align with the first slot 23 on the baffle plate 22 to be grasped. Then, the first locking member 333 is driven by the telescopic motor 331 to move towards the baffle plate 22, so that the first locking member 333 extends into the first slot 23. After the first locking member 333 extends into the first slot 23, the first locking member 333 is driven to rotate by the rotary motor 332 so that the first locking member 333 engages with the first slot 23, thereby completing the grasping work of the robot arm 33.

[0055] In some embodiments, such as Figure 6 As shown, the inner wall of the window 24 is provided with an elastic buckle 25. The baffle 22 is detachably installed inside the window 24 through the elastic buckle 25. In this embodiment, after the baffle 22 is placed inside the window 24, the elastic buckle 25 engages with the baffle 22, thereby limiting the baffle 22 inside the window 24, thus realizing the detachable connection between the baffle 22 and the fixing frame 21.

[0056] In some embodiments, such as Figure 6 As shown, the elastic buckle 25 has a "V" shaped structure. One end of the elastic buckle 25 is connected to the inner wall of the window 24, and the other end of the elastic buckle 25 is suspended in the air.

[0057] For example, in this embodiment, the side wall of the shield 22 is provided with a snap-fit ​​groove, and the elastic snap 25 has a “V” shaped structure. When the shield 22 is limited to the window 24, the protrusion of the “V” shaped structure of the elastic snap 25 extends into the snap-fit ​​groove of the side wall of the shield 22, thereby detachably setting the shield 22 in the window 24.

[0058] In another alternative embodiment, a limiting member may also be provided inside the window 24. The limiting member is located on the side away from the shading control device 30, and the elastic buckle 25 is located on the side close to the shading control device 30. When the shading plate 22 is placed inside the window 24, the limiting member contacts one side of the shading plate 22, and the protrusion of the "V"-shaped structure of the elastic buckle 25 contacts the other side of the shading plate 22. By having the limiting member and the elastic buckle 25 simultaneously contact both sides of the shading plate 22, the shading plate 22 is detachably installed in the window 24.

[0059] In some embodiments, such as Figure 7 As shown, it also includes a lens 40. Each of the multiple sensor devices 11 has a lens 40 on one side of its receiving end. It can be understood that in this embodiment, each sensor device 11 on the sensor integration board 10 is provided with a separate lens 40, so that the working sensor device 11 can use the corresponding lens 40, reducing the invalid exposure of the pixel area and ensuring the imaging quality of the sensor device 11.

[0060] In some embodiments, such as Figure 1 As shown, it also includes a reflector 50, which is disposed between the lens 40 and the sensor integration plate 10. The reflector 50 can reflect the light entering the lens 40 to the sensor device 11, preventing gamma rays, neutrons and the like from hitting the sensor device 11 directly, thereby extending the overall lifespan of the camera.

[0061] This embodiment also provides another optional implementation method, such as... Figure 8 As shown, in this embodiment, the anti-radiation shielding device includes a shielding plate with a window for exposing the sensor device. The shielding control device is connected to the shielding plate and changes the window position by driving the shielding plate to move. Specifically, in this embodiment, when the damage level of the current sensor device 11 is detected to exceed a preset threshold (e.g., the proportion of failed pixels exceeds 5%), the shielding control device drives the shielding plate to move to change the window position, so that the window can move to another sensor device that is functioning normally, thereby exposing the sensor device to the window, so that the camera can continue to operate normally, thereby extending the overall lifespan of the camera.

[0062] For example, in this embodiment, the occlusion control device can also be used to drive the sensor integration board to move, thereby changing the position of the sensor device on the sensor integration board, and thus enabling the window on the occlusion board to occlude or expose the sensor device.

[0063] For example, the occlusion control device 30 includes a first drive slide rail and a second drive slide rail. The first drive slide rail is used to drive the occlusion plate to move along a first direction, and the second drive slide rail is used to drive the occlusion plate to move along a second direction. The first direction is perpendicular to the second direction. It can be understood that, in the embodiment, the occlusion plate can achieve arbitrary movement in a two-dimensional direction under the combined action of the first drive slide rail and the second drive slide rail, thereby changing the position of the window on the occlusion plate.

[0064] It should be noted that this application is not limited to the above-described embodiments. The above embodiments are merely examples, and any embodiments with the same structure and effect as the technical concept within the scope of this application are included in the technical scope of this application. Furthermore, various modifications that can be conceived by those skilled in the art to the embodiments, and other ways of constructing by combining some of the constituent elements of the embodiments, without departing from the spirit of this application, are also included in the scope of this application.
