Description

Technical Field

[0001] The present invention relates to a chlorophyll fluorescence imaging device, belonging to the technical field of chlorophyll fluorescence imaging technology. Background Art

[0002] The chlorophyll fluorescence phenomenon plays an important role in the study of plant photosynthesis. It can not only intuitively reflect the primary reaction processes of photosynthesis such as light energy absorption, excitation energy transfer, and photoreaction, but also be closely related to subsequent key processes such as electron transfer, proton gradient establishment, ATP synthesis, and CO2 fixation. It can be said that almost all dynamic changes in the photosynthesis process can be clearly shown through chlorophyll fluorescence. Therefore, using chlorophyll fluorescence as an important probe for photosynthesis research has been widely explored and applied in the scientific research field. In actual detection, a chlorophyll fluorescence imaging device is usually used to accurately detect plants.

[0003] Currently, chlorophyll fluorescence imaging is mainly divided into two modes: indoor detection and outdoor detection. Among them, the outdoor detection type of chlorophyll fluorescence imaging device generally consists of a flexible movable rack, a scanning imager, a lifting shielding module, and a terminal module. When carrying out the detection work, first, the rack needs to be moved to the target detection position, and then the lifting shielding module is used to completely cover the plant to be detected to create a dark detection environment. Then, the scanning imager emits light of a specific wavelength to the plant. After the chlorophyll molecules in the plant leaves absorb light energy, they will quickly jump from the ground state to the excited state. Since the chlorophyll molecules in the excited state are extremely unstable, they will quickly return to the ground state through ways such as emitting fluorescence. At this time, the scanning imager can sensitively capture the fluorescence signal emitted by chlorophyll and convert it into data information, which is transmitted to the terminal module in real time. The terminal module deeply processes and analyzes these data, accurately calculates the chlorophyll fluorescence parameters, and then generates an image based on these parameters to intuitively reflect the photosynthetic physiological state of the plant.

[0004] However, affected by factors such as humidity and temperature in the outdoor natural environment, water films and other substances are easily formed and aggregated on the surface of plant leaves, and the distribution of these water films is often uneven. During the detection process, the water film will strongly reflect and refract the light irradiated by the scanning imager, resulting in the scattering of the excited fluorescence signal. Eventually, the image generated using the chlorophyll fluorescence parameters is very likely to have problems such as artifacts and blurring, seriously affecting the effect and quality of fluorescence imaging, and thus interfering with the accuracy of the assessment of the true physiological state of plants.

Then, the fixed parts of four lifting devices, whose movable parts are connected to the upper end of the horizontal part of the movable plate 9 and are located outside the outer cylinder 21, are respectively installed at the four corner positions at the lower end of the top plate 2. The four lifting devices are used in cooperation to drive the movable plate 9 to move up and down. The lifting device can adopt the second electric push rod 94. A plurality of round rods 93 that penetrate the top plate 2 and are slidably connected to the top plate 2 are equidistantly installed at the upper end of the vertical part of the movable plate 9. The plurality of round rods 93 are used in cooperation. On the one hand, they guide the movement of the movable plate 9, and on the other hand, they increase the installation strength of the movable plate 9; The scanning imager 23 located inside the outer cylinder 21 is installed at the lower end of the top plate 2.

Through the touch display screen 11, it is used for control on the one hand and to display the imaging result on the other hand. Then, the terminal 12, which is electrically connected to the touch display screen 11 and the scanning imager 23 respectively, is installed on one side end of the frame 1. Through the terminal 12, the scanning data is analyzed and calculated. The power supply 16 for providing electric energy is installed at the other end of the frame 1. Through the power supply 16, electric energy is provided for components such as the telescopic device; Install the fixing part of the telescopic device extending out of the left side of the rack 1 on the left end of the vertical part of the movable plate 9. Through the telescopic device, drive the annular frame 3 to move left and right. The telescopic device can adopt the first electric push rod 92, and connect the right end of the annular frame 3 with the movable part of the telescopic device. Through the annular frame 3, provide an installation carrier for components such as the movable cylinder 4. Then, symmetrically install the two telescopic rods 91 on the front and back sides of the telescopic device between the movable plate 9 and the annular frame 3. The two telescopic rods 91 are used in cooperation to guide the movement of the annular frame 3, and rotatably connect the movable cylinder 4 to the inner wall of the annular frame 3. Through the movable cylinder 4, provide an installation carrier for components such as the air pipe 42; Install the annular gear 31 on the outer end of the movable cylinder 4. Through the annular gear 31, rotate the movable cylinder 4, and engage the rotating gear 5 on the upper end of the annular gear 31. Through the rotating gear 5, drive the annular gear 31 to rotate. Then, install the fixing part of the driving device with the output shaft connected to the right end of the rotating gear 5 on the upper end of the annular frame 3. Through the driving device, drive the rotating gear 5 to rotate. The driving device can adopt the motor 8, and rotatably connect the annular air box 32 located below the annular gear 31 and outside the driving device to the outer end of the movable cylinder 4, and the annular air box 32 is arranged on the upper end of the annular frame 3. Through the annular box, synchronously supply gas to multiple air pipes 42; Install multiple air pipes 42 arranged in a tapered structure with a narrow lower part and a wide upper part, passing through the movable cylinder 4 and communicating with the annular air box 32, equidistantly on the inner wall of the movable cylinder 4. The multiple air pipes 42 are used in cooperation to transport gas outward, and install the air extraction device located on one side of the driving device and outside the annular air box 32 with the outlet part communicating with the annular air box 32 on the upper end of the annular frame 3. Through the air extraction device, transport gas into the annular air box 32. The air extraction device can adopt the air pump 6, and then install the heater 7 located on the other side of the driving device and outside the annular air box 32 with the outlet part communicating with the inlet part of the air extraction device on the upper end of the annular frame 3. Through the heater 7, heat the extracted gas, and the inlet part of the heater 7 is arranged facing the direction of the driving device. On the one hand, assist in dissipating heat from the motor 8, and on the other hand, pre-heat the gas entering the heater 7.

[0020] During use, start the two electric drive wheels 13. The two electric drive wheels 13 work and drive the rack 1 to move with the assistance of the auxiliary wheels 15. At the same time, the two electric turntables 14 can be started to drive the auxiliary wheels 15 to rotate, so as to turn the rack 1, and then move the rack 1 to the initial position. Then start the first electric push rod 92 to drive components such as the annular frame 3 to move outward to a suitable position, so that the annular frame 3 is located directly above a plant to be detected; Then, start the four second electric push rods 94 to drive the movable plate 9 to move downward, and then move components such as the first electric push rod 92 and the annular frame 3 downward. At the same time, start the air pump 6, the heater 7, and the motor 8. When the motor 8 operates, it drives the rotating gear 5 to rotate. Since the rotating gear 5 meshes with the annular gear 31, the rotation of the rotating gear 5 causes the annular gear 31 to rotate, thereby causing the movable cylinder 4 to rotate, and then causing the multiple air pipes 42 to rotate synchronously. When the heater 7 operates, it heats the gas entering the heater 7. When the air pump 6 operates, it extracts the heated gas in the heater 7, and then conveys the heated gas to the annular air box 32. Then, the heated gas in the annular air box 32 is diverted into the multiple air pipes 42, and then the multiple air pipes 42 spray the heated gas outward; Since the multiple air pipes 42 are in a rotating state, the sprayed heated gas will be in a spiral state. At the same time, components such as the annular frame 3 are in a downward moving state, and then the heated gas is sprayed onto the plants to be detected comprehensively from top to bottom, so as to remove substances such as the water film formed on the leaf surfaces of the plants to be detected, effectively reducing the probability of artifacts, blurring, etc. in imaging due to factors such as the water film and other substances on the leaf surfaces, effectively ensuring the fluorescence imaging effect and quality, and effectively ensuring the accuracy of the evaluation of the plant physiological state; Then, use the four second electric push rods 94 to make components such as the movable plate 9 return upward to their original positions. Then, use the two electric drive wheels 13, the two electric turntables 14, and the two auxiliary wheels 15 to move components such as the frame 1 along the planting ridge to the next detection position. Then, use the four second electric push rods 94 to move components such as the movable plate 9 and the annular frame 3 downward. At this time, through the air pump 6, the heater 7, the motor 8, the annular air box 32, and the multiple air pipes 42, spray the heated gas onto the next plant to be detected comprehensively, so as to remove substances such as the water film formed on the leaf surfaces of the next plant to be detected; After the movable plate 9 moves down to the limit position, the plant to be detected after the removal of substances such as the water film passes through the through hole 95 and enters the shielding cloth 22, so that the plant to be detected is in a dark environment. Then, use the scanning imager 23 to irradiate the plant to be detected with light of a specific wavelength, so that the chlorophyll molecules in the plant to be detected absorb light energy and transition from the ground state to the excited state. The excited chlorophyll molecules are unstable and will return to the ground state in the form of emitting fluorescence, etc. The scanning imager 23 captures the fluorescence signal emitted by the chlorophyll, converts the fluorescence signal into data, and transmits the collected data to the terminal 12. Then, the terminal 12 processes and analyzes the data, calculates the chlorophyll fluorescence parameters, forms an image according to the chlorophyll fluorescence parameters, and at the same time transmits the corresponding image data to the touch display screen 11 for display, so as to display the spatial distribution and dynamic changes of chlorophyll fluorescence on the plant surface in the form of an image, reflecting the photosynthetic physiological status of the plant.

[0021] Embodiment 2: The second electric push rod 94 and the shielding cloth 22 are used to cover the plant to be detected. With the help of the scanning imager 23, the terminal 12 and the touch display screen 11, chlorophyll fluorescence imaging is performed on the plant inside the cover to determine its photosynthetic physiological condition. At the same time, when the second electric push rod 94 works, it also drives components such as the movable plate 9, the first electric push rod 92 and the annular frame 3 to move downward; and through the motor 8, the rotating gear 5, the annular gear 31 and the movable cylinder 4, the synchronous rotation of multiple air pipes 42 is realized. In cooperation with the heater 7, the air pump 6 and the annular air box 32, heated gas is conveyed into the air pipes 42, and then the plant is comprehensively sprayed from top to bottom to remove substances such as water films on the leaf surface. However, during the contact between the heated gas and the leaves, the possibility of damage to the plant leaves is relatively large, which will not only affect the effect and quality of subsequent fluorescence imaging, but also have an adverse impact on plant growth.

At the same time, use the motor 8, the rotating gear 5, the annular gear 31, and the movable cylinder 4 to synchronously rotate the multiple air pipes 42 and the multiple rectangular cylinders 41, and through the heater 7 and the air pump 6, send heated gas into the annular air box 32. Then, the heated gas in the annular air box 32 is split into the multiple air pipes 42, and then the multiple air pipes 42 will spray the heated gas outward; The sprayed heated gas will exert a thrust on the corresponding water-absorbing cloth 43, so that the water-absorbing cloth 43 wound around the second shaft 4182 is released outward, and the second shaft 4182 rotates, thereby contracting the elastic member 4181, so that the elastic member 4181 generates an elastic force, and the water-absorbing cloth 43 extends outward from the rectangular cylinder 41. The sprayed heated gas will pass through the water-absorbing cloth 43 and continue to be sprayed outward, and then spray the heated gas onto the plant to be detected comprehensively from top to bottom, so as to remove substances such as the water film formed on the leaf surface of the plant to be detected, achieve slowing down the spraying speed of the heated gas, effectively reduce the probability of damage to the leaves of the plant to be detected caused by the spraying of the heated gas, effectively ensure the fluorescence imaging effect and quality, and effectively ensure that the plant can grow normally after detection; At the same time, the sprayed heated gas will evaporate the water on the leaf surface of the plant to be detected. At this time, the water-absorbing cloth 43 extending outward from the rectangular cylinder 41 will absorb the evaporated water, realizing timely absorption of the evaporated water generated by heating, effectively reducing the probability of re-condensation on the leaf surface of the plant to be detected due to the evaporated water, effectively ensuring the fluorescence imaging effect and quality. After the substances such as the water film formed on the leaf surface of the plant to be detected are removed, turn off the heater 7, the motor 8, and the air pump 6, and under the elastic force of the elastic member 4181, rotate the second shaft 4182, thereby winding up the water-absorbing cloth 43; During the winding process, the water-containing area of the water-absorbing cloth 43 will pass between the two rollers 4161. At this time, the two rollers 4161 will squeeze the water-absorbing cloth 43, so as to drain the water absorbed by the water-absorbing cloth 43. The drained water flows downward and enters the connecting pipe 4162, and then the drained water enters the collecting cylinder 417 through the connecting pipe 4162, realizing timely drainage of the water absorbed by the water-absorbing cloth 43, effectively reducing the probability of blocking the sprayed heated gas due to the water-containing area in the water-absorbing cloth 43, and being able to effectively remove substances such as the water film formed on the leaf surface of the plant to be detected, effectively ensuring the fluorescence imaging effect and quality; Then, four second electric push rods 94 are used to make components such as the movable plate 9 return upward to their original positions. Then, two electric drive wheels 13, two electric turntables 14, and two auxiliary wheels 15 are used to move components such as the frame 1 along the planting ridge to the next detection position. Then, four second electric push rods 94 are used to move components such as the movable plate 9 and the annular frame 3 downward. At this time, a gas pump 6, a heater 7, a motor 8, an annular gas box 32, and multiple air pipes 42 are used to spray heated gas comprehensively onto the next plant to be detected, so as to remove substances such as the water film formed on the leaf surface of the next plant to be detected; After the movable plate 9 moves downward to the limit position, the plant to be detected after the removal of substances such as the water film passes through the through hole 95 and enters the shielding cloth 22, so that the plant to be detected is in a dark environment. Then, a scanning imager 23, a terminal 12, and a touch display screen 11 are used to display the spatial distribution and dynamic changes of chlorophyll fluorescence on the plant surface in the form of images, reflecting the photosynthetic physiological status of the plant; At the same time, the round box 418 can be moved upward, so that multiple positioning rods move upward, and then the positioning rods are separated from the positioning holes, and the circular rod moves upward along the circular hole, so as to release the restricted installation between the round box 418 and the first mounting frame 411. Then, the auxiliary rod 4131 is rotated. Since the auxiliary rod 4131 is threadedly connected to the threaded hole 4132 and the auxiliary rod 4131 is threadedly connected to the rotating plate 413, the auxiliary rod 4131 rotates and moves upward at the same time, and then the auxiliary rod 4131 is separated from the threaded hole 4132; Then, the auxiliary rod 4131 is used to rotate the rotating plate 413, and then the first shaft 414 rotates, so as to wind up the water absorption cloth 43, and components such as the second shaft 4182 and the round box 418 rotate accordingly. Then, the auxiliary rod 4131 is reconnected to the corresponding threaded hole 4132, and the positioning rod is reinserted into the positioning hole, so that the round box 418 is reinstalled restrictively, realizing the adjustment of the water absorption position in the water absorption cloth 43, effectively reducing the probability of damage to the water absorption cloth 43 caused by long-term water absorption operation, further effectively reducing the probability of damage to the leaves of the plant to be detected, and effectively ensuring the fluorescence imaging effect and quality.

[0024] Embodiment 3: The second electric push rod 94 is used to drive the shielding cloth 22 to completely cover the plant to be detected. Subsequently, a scanning imager 23, a terminal 12, and a touch display screen 11 are used to perform chlorophyll fluorescence imaging on the plant in the cover to judge its photosynthetic physiological state. However, for plants to be detected in a specific growth cycle, their leaves are prone to aging, and the fluorescence parameters in the aging leaves are also collected, resulting in an increased probability of errors in the collected data, which in turn affects the fluorescence imaging effect and quality.

[0025] To solve the above problems, as Figure 11As shown in the figure, the mounting cylinder 951 located inside the shielding cloth 22 is mounted on the inner wall of the through hole 95. Through the mounting cylinder 951, a mounting carrier is provided for components such as the shielding plate 952. The lower ends of a plurality of shielding plates 952, which are arranged in a tapered structure with a narrow upper part and a wide lower part, have cross-sections in an arc shape and are located inside the mounting cylinder 951, and are all hinged to the lower end of the mounting cylinder 951. The plurality of shielding plates 952 are used in cooperation to shield the aging leaves of the plant to be detected. Then, the fixed parts of a plurality of third electric push rods 953, which are movably arranged on the outer ends of the plurality of shielding plates 952 respectively, are equidistantly and movably mounted on the outer end of the mounting cylinder 951. Through the third electric push rods 953, the shielding plates 952 are driven to rotate.

[0026] During use, first, by using two electric drive wheels 13, two electric turntables 14, and two auxiliary wheels 15, the frame 1 is moved to the initial position, and by using the first electric push rod 92, components such as the annular frame 3 are driven to move outward to a suitable position, so that the annular frame 3 is located directly above a plant to be detected. Then, by using four second electric push rods 94, components such as the movable plate 9, the first electric push rod 92, and the annular frame 3 are driven to move downward. At the same time, by using the motor 8, the rotating gear 5, the annular gear 31, and the movable cylinder 4, a plurality of air pipes 42 and a plurality of rectangular cylinders 41 are synchronously rotated, and through the heater 7 and the air pump 6, heated gas is conveyed into the annular air box 32. Then, the heated gas in the annular air box 32 is split into a plurality of air pipes 42, and then the plurality of air pipes 42 will spray the heated gas outward; The sprayed heated gas will exert a thrust on the corresponding water-absorbing cloth 43, so that the water-absorbing cloth 43 extends outward from the rectangular cylinder 41. The sprayed heated gas will penetrate through the water-absorbing cloth 43 and continue to be sprayed outward, so as to spray the heated gas onto the plant to be detected comprehensively from top to bottom, thereby removing substances such as the water film formed on the leaf surface of the plant to be detected. The water-absorbing cloth 43 extending outward from the rectangular cylinder 41 will absorb the evaporated water. After the substances such as the water film formed on the leaf surface of the plant to be detected are removed, two rollers 4161 are used to drain the water absorbed by the water-absorbing cloth 43, and the drained water is collected through the connecting pipe 4162 and the collecting cylinder 417; Then, by using four second electric push rods 94, components such as the movable plate 9 are returned upward to the original position. Then, by using two electric drive wheels 13, two electric turntables 14, and two auxiliary wheels 15, the frame 1 and other components are moved along the planting ridge to the next detection position. Then, by using four second electric push rods 94, components such as the movable plate 9 and the annular frame 3 are moved downward. At this time, through the air pump 6, the heater 7, the motor 8, the annular air box 32, and the plurality of air pipes 42, heated gas is comprehensively sprayed onto the next plant to be detected, thereby removing substances such as the water film formed on the leaf surface of the next plant to be detected; After the movable plate 9 moves down to a suitable position, the plant to be detected after the removal of substances such as the water film passes through the through hole 95 and enters the shielding cloth 22, so that the plant to be detected is in a dark environment. If there are aging leaves on the plant to be detected, multiple third electric push rods 953 are started simultaneously, so as to drive multiple shielding plates 952 to swing inwards synchronously to a suitable position, realizing the shielding of the aging leaves on the plant to be detected, effectively reducing the probability of errors in the collected data caused by the aging leaves, effectively ensuring the fluorescence imaging effect and quality, and then using the scanning imager 23, the terminal 12 and the touch display screen 11, so as to display the spatial distribution and dynamic changes of chlorophyll fluorescence on the plant surface in the form of images, reflecting the photosynthetic physiological status of the plant.
