Description

Technical Field

[0001] This invention relates to the field of image acquisition technology, specifically to an imaging system for an all-sky cloud imager. Background Technology

[0002] When a camera is pointed directly at the sky to take a picture, the sun and its surrounding pixels will be overexposed in the sky image captured under adaptive exposure value, resulting in some sky texture information being submerged.

[0003] Chinese patent discloses an imaging system for an all-sky cloud imager (CN212850683U). The light occlusion module of this technical solution is periodically turned on. When fully turned on, it can acquire a complete and unobstructed original sky image under sunlight, reducing cloud cover calculation errors caused by sun occlusion. In addition, adjusting the photosensitive chip's photosensitive time can reduce overexposure of the image.

[0004] If the light chopper uses a reflection mechanism, the light will be scattered to other locations inside the device. If the light chopper uses a light absorption mechanism, its temperature will rise under the influence of light. Because the light chopper is a dynamic structure, the device needs to provide sliding space for it; since the light needs to be perpendicular to the imaging device, the longitudinal area of ​​the sliding space cannot be blocked; if the light chopper blocks light and heats up, it will affect the internal temperature of the device, and the heat exchange structure cannot directly act on the light chopper, thus resulting in low internal temperature control efficiency. Summary of the Invention

[0005] The purpose of this invention is to provide an imaging system for an all-sky cloud imager that adjusts the heat exchange method according to the motion state of the light-cutter plate, matching the heat exchange method with the temperature rise state under different motion states of the light-cutter plate, thereby achieving dynamic temperature control. Furthermore, it utilizes sliding friction to control the connection and switching of the T-shaped shunt tube, the bottom heat exchange pipeline, and the light-cutter heat exchange pipeline, allowing the heat exchange method to be adjusted according to the motion trajectory of the light-cutter plate. This simplifies the structural volume and complexity, and eliminates the need for other electrical control mechanisms, meeting the requirements for long-term outdoor operation, thus solving the problems mentioned in the background art.

Detailed Implementation

[0026] Please see Figures 1-5 In this embodiment:

[0027] Includes a housing 100, inside which a control module 200 and a compartmentalized dynamic temperature control module 300 are installed. The control module 200 controls the sliding of the light chopper 2 through a reciprocating controller 1. The light chopper 2 is located above the imaging device.

[0028] The control module 200 controls the long-blocking mode and periodic blocking mode of the acerola 2 via the reciprocating controller 1, which is existing technology and will not be described in detail here. The compartmentalized dynamic temperature control module 300 can use gas heat exchange or liquid heat exchange.

[0029] It is known that the light chopper 2 heats up when it blocks and absorbs light. In the long-block mode, the light chopper 2 absorbs light for a longer time and has a higher rate of temperature change. In the periodic-block mode, the light chopper 2 absorbs light for a relatively shorter time and has a lower rate of temperature change.

[0030] This technical solution adjusts the heat exchange method according to the motion state of the light-cutting plate 2, so that the heat exchange method matches the temperature rise state under different motion states of the light-cutting plate 2, thereby achieving dynamic temperature control.

[0031] The specific method is as follows:

[0032] The compartmentalized dynamic temperature control module 300 also includes an extended heat exchanger 3 and a temperature control module 4. The extended heat exchanger 3 is located below the imaging device. A T-shaped diversion slide tube 5 is installed in the reciprocating controller 1. A beam-cutting heat exchange pipeline 8 is installed in the beam-cutting plate 2. A bottom heat exchange pipeline 7 is installed in the extended heat exchanger 3.

[0033] The temperature control module 4 itself includes a power source and a temperature control source, with the medium being gas or liquid. Temperature control can be achieved through electrical temperature control or by using a cooling / heating medium.

[0034] When the ablation heat exchange pipe 8 slides out to the outside of the reciprocating controller 1 and blocks the imaging device, the ablation heat exchange pipe 8, the T-shaped diversion slide pipe 5, and the bottom heat exchange pipe 7 form a passage and are supplied with liquid in a closed loop by the temperature control module 4.

[0035] When the light-cutter plate 2 slides to the outside, it tends to heat up. The temperature control module 4, the T-shaped flow divider 5, and the bottom heat exchanger 7 form a flow path. Specifically, the flow direction is a closed loop between the T-shaped flow divider 5 and the light-cutter heat exchanger 8, and a closed loop between the T-shaped flow divider 5 and the bottom heat exchanger 7. The light-cutter plate 2 and the extended heat exchanger 3 are located on the upper and lower sides of the imaging device, respectively, to uniformly control the temperature inside the entire device.

[0036] When the light chopper 2 is on for an extended period, it indicates high light intensity and a significant impact on the imaging device, thus greatly affecting the internal temperature of the equipment. In this situation, the motion of the light chopper 2 is coupled with the dynamic heat transfer efficiency of this technical solution.

[0037] When the light-cutting heat exchange pipe 8 slides into the inside of the reciprocating controller 1 and exposes the imaging device, the T-shaped shunt slide pipe 5 and the bottom heat exchange pipe 7 form a passage and are supplied with liquid in a closed loop by the temperature control module 4.

[0038] When the light chopper 2 is closed for an extended period, it indicates low light intensity and minimal impact on the imaging device. Consequently, the light has a low effect on the internal temperature of the equipment. In this case, heat exchange is achieved solely through the T-shaped diversion slide tube 5 and the bottom heat exchange pipe 7. Due to the short stroke and short fluid residence time, heat exchange is faster.

[0039] Although the synchronous or independent connection of the T-shaped diversion slide tube 5, the bottom heat exchange pipe 7, and the slashed heat exchange pipe 8 can be controlled by valves, the following improvements are made to reduce the size and electrical control components:

[0040] There are two T-shaped diversion slide tubes 5. Each T-shaped diversion slide tube 5 consists of a sliding part 51, a connecting part 52, and a connecting part 53. The two sliding parts 51 are located inside the two open ends of the ablation heat exchange pipeline 8 and slide relative to each other. The two connecting parts 52 are respectively connected to the liquid delivery end and the return end of the temperature control module 4. The connecting part 53 connects the sliding parts 51 and the connecting parts 52 to the bottom heat exchange pipeline 7. A sliding resistance piston 6 is slidably connected inside the T-shaped diversion slide tube 5. The sliding resistance piston 6 includes a resistance slide plug 61 and a guide. The flow slider 62 and the connecting rod 63 are provided. The inner wall of the slash heat exchange pipe 8 is provided with a rubber layer 81. The resistance slider 61 contacts and slides with the rubber layer 81. The resistance slider 61 and the flow slider 62 are fixedly connected by the connecting rod 63. The flow slider 62 moves synchronously with the resistance slider 61. Several annularly distributed flow holes 611 are opened on the top of the resistance slider 61. The inner wall of the end of the sliding part 51 is fixedly connected with a fitting ring 511. The width of the fitting ring 511 covers the diameter of the flow holes 611.

[0041] Please see Figure 4 When the acerbium 2 moves outward, the friction force exerted by the rubber layer 81 on the resistance slide 61 drives the resistance slide 61 to move outward. At this time, the drainage hole 611 separates from the fitting ring 511, and the drainage hole 611 is connected to the inner cavity of the T-shaped diversion slide tube 5.

[0042] When the acerbic plate 2 moves into the reciprocating controller 1, the friction of the rubber layer 81 drives the resistance plug 61 to move inward. The resistance plug 61 presses against the fitting ring 511, blocking the drainage hole 611. The resistance plug 61 slides relative to the rubber layer 81, and the sliding part 51 is closed, so the fluid in the acerbic heat exchange pipeline 8 does not move. The connecting rod 63 moves with the resistance plug 61 and drives the drainage slider 62 to slide. When the T-shaped tube 621 is aligned with the connecting part 53, the T-shaped diversion slide tube 5 and the bottom heat exchange pipeline 7 are connected. Although some fluid enters the interior of the T-shaped diversion slide tube 5 through the T-shaped tube 621, the port of the sliding part 51 is blocked, and the fluid cannot enter the acerbic heat exchange pipeline 8, thus realizing the switching function.

[0043] This method utilizes sliding friction to control the connection and switching of the T-shaped diversion slide tube 5, the bottom heat exchange pipe 7, and the slashing heat exchange pipe 8, so that the heat exchange mode is adjusted according to the movement trajectory of the slashing plate 2, simplifying the structural volume and complexity, and requiring no other electrical control mechanism, which meets the requirements for long-term outdoor operation.

[0044] The bottom of the resistance slider 61 is fixedly connected with a raised rib 612, and the surface of the raised rib 612 is fixedly connected with at least three abutment blocks 613 arranged in a ring.

[0045] To prevent the resistance plug 61 from separating from the sliding part 51, a raised rib 612 is provided. When the resistance plug 61 moves outward, the abutment 613 contacts the fitting ring 511, the raised rib 612 cannot continue to move, and a communication channel is reserved between the T-shaped diversion slide tube 5 and the slash heat exchange pipeline 8.

[0046] The drainage slider 62 has a T-shaped tube 621 inside, which connects the upper and lower end faces and the side face of the drainage slider 62 respectively. The side face of the T-shaped tube 621 is fixedly connected to an elastic cavity 622.

[0047] During the movement of the acerbium 2 into the reciprocating controller 1, the connecting end of the T-shaped tube 621 and the connecting part 53 is in a closed stage. When the sliding part 51 contains residual liquid and the sliding piston 6 moves towards the reciprocating controller 1, the fluid pressure in the T-shaped diversion tube 5 increases, causing the elastic cavity 622 to undergo elastic deformation and accumulate fluid, thus preventing excessive pressure from causing leakage in the sliding sealing structure.

[0048] The outer wall of the sliding part 51 is slidably connected to the rubber layer 81, and a Teflon film is attached to the outer wall of the sliding part 51.

[0049] Since the sliding part 51 does not need to rely on friction to control its movement, the non-stick properties of the Teflon film combined with the rubber layer 81 can achieve sliding sealing while reducing some of the friction.

[0050] The reciprocating controller 1 has a drive area 400 inside, which includes the space between two adjacent T-shaped diverter tubes 5 or on both sides of the chopper plate 2.

[0051] Please see Figure 3 The T-shaped diversion slide tube 5, the bottom heat exchange pipe 7, and the slashed heat exchange pipe 8 are arranged longitudinally. The T-shaped diversion slide tube 5 is symmetrically distributed, forming a driving zone 400 in the middle, and driving zones 400 can also be formed on both sides. A motor screw drive mechanism or a gear and rack drive mechanism, etc., can be installed in the driving zone 400.

[0052] Additional notes:

[0053] This technical solution has two specific implementation methods:

[0054] Execution method A:

[0055] Please see Figure 3 When the scalpel plate 2 is in the open state, the flow guide slider 62 is located at the sliding part 51, and the connecting part 52 is exposed. The T-shaped diversion slide tube 5 is simultaneously connected to the bottom heat exchange pipe 7 and the scalpel heat exchange pipe 8. The compartment dynamic temperature control module 300 has two return ports, one connected to the T-shaped diversion slide tube 5 and the other independently connected to the scalpel heat exchange pipe 8. The fluid is transported through the T-shaped diversion slide tube 5 and diverted to the bottom heat exchange pipe 7 and the scalpel heat exchange pipe 8 through the sliding part 51 and the connecting part 53. When the scalpel plate 2 is in the closed state, the side path of the T-shaped tube 621 is connected to the connecting part 53, and the T-shaped diversion slide tube 5 and the bottom heat exchange pipe 7 are in a connected state to achieve heat exchange.

[0056] Execution method B:

[0057] Please see Figure 2 and Figure 5 When the shaving plate 2 is in the open state, the connecting part 52 and the connecting part 53 are in an open state due to the influence of the flow guide slider 62, and the fluid mainly achieves heat exchange through the T-shaped diversion slide tube 5 and the shaving heat exchange pipe 8. When the shaving plate 2 is in the closed state, the T-shaped diversion slide tube 5 and the bottom heat exchange pipe 7 are in a connected state to achieve heat exchange.

[0058] It is worth noting that during application, it is necessary to reasonably control the flow rate or appropriately increase the sliding friction between the rubber layer 81 and the resistance plug 61 to avoid the fluid kinetic energy overcoming the sliding friction between the resistance plug 61 and the rubber layer 81, causing the resistance plug 61 to close prematurely.

[0059] It is worth noting that during the application process, it is necessary to reasonably control the flow rate or appropriately increase the sliding friction between (81) and (61) to avoid the fluid kinetic energy overcoming the sliding friction between (61) and (81) and causing (61) to close prematurely.

[0060] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
