Description

Technical Field

[0001] This invention belongs to the field of pesticide residue detection technology, specifically involving a pesticide residue detection system for fruits and vegetables that utilizes artificial intelligence algorithms. Background Technology

[0002] Pesticide residues refer to the trace amounts of pesticide residues, toxic metabolites, degradation products, and impurities remaining in agricultural products, soil, and water after pesticide use. Their formation is closely related to the application method and degradation rate of pesticides. Excessive or improper use of pesticides can lead to pesticide residue exceeding the standard. If pesticide residues enter the human body through the food chain, they may cause chronic or acute harm to organs, the nervous system, etc. Therefore, pesticide residue content is one of the core indicators for measuring the quality and safety of agricultural products. Existing pesticide residue detection technologies are mainly divided into two categories: precise laboratory detection and rapid screening. Laboratory detection is based on chromatography-mass spectrometry technology, including gas chromatography-mass spectrometry and liquid chromatography-mass spectrometry. These technologies can achieve precise qualitative and quantitative analysis of pesticide residues.

[0003] Gas chromatographs and liquid chromatographs are often expensive and have long detection times. Therefore, pesticide residue detection cards are often used for rapid screening of pesticide residues. However, existing pesticide residue detection cards require manual mixing of extracts and fruit and vegetable samples, as well as manual operations such as removing the membrane from the detection card, wetting the detection card, and squeezing the card together. The process is quite complicated. Furthermore, the reaction of the two tablets on both sides of the detection card requires the participation of the human body temperature. It is difficult to keep the body temperature of the testing personnel constant during multiple tests. In addition, it is difficult to ensure that the squeezing time is consistent for each test. The consistency of the reaction time of the tablets is difficult to guarantee, resulting in unstable test results. Moreover, in the current technology, after the two tablets of the detection card react, the testing personnel need to judge the color of the colorimetric strip with the naked eye. This results in strong subjectivity and low accuracy. The color observed by the naked eye is also easily affected by external light sources. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a fruit and vegetable pesticide residue detection system using artificial intelligence algorithms.

[0005] The technical solution adopted to solve the above-mentioned technical problems is: a fruit and vegetable pesticide residue detection system using artificial intelligence algorithms, including a first frame and a reaction test chamber mechanism. A first transmission mechanism is rotatably connected to the first frame. The first transmission mechanism includes a first gear rotatably connected to the first frame. A first pulley is coaxially fixed to the top of the first gear. A first synchronous belt is meshed with the outside of the first pulley. A second gear is meshed with one side of the first gear. The second gear is rotatably connected to the first frame. A second pulley is coaxially fixed to the top of the second gear. A second synchronous belt is meshed with the outside of the second pulley. A second transmission mechanism and a third transmission mechanism are rotatably connected to the first frame. A second frame is fixed to the top of the first frame.

[0006] A winding mechanism is rotatably connected to the second frame, and an unwinding mechanism is rotatably connected to the second frame. The unwinding mechanism includes an unwinding assembly, and a test paper roll is fixed to the top of the unwinding assembly. A conveying mechanism is fixed to one end of the first frame. A color developing paper roll conveying mechanism is provided on the second frame. A base mechanism is fixed to one end of the first frame, and a first cylinder mechanism and a second cylinder mechanism are installed on the base mechanism.

[0007] A reaction testing chamber mechanism is fixed to the top of the conveying mechanism. The reaction testing chamber mechanism includes a housing, an industrial control computer is fixed to the outside of the housing, and a small air conditioner is also embedded in the housing. An electric lifting door is slidably connected to one end of the housing. A shooting mechanism is fixed to the inside of the reaction testing chamber mechanism. The shooting mechanism includes a mounting base plate fixed to the inside of the housing. A wide color gamut camera and a fill light are fixed to the mounting base plate. An extraction spray mechanism is fixed to the top of the reaction testing chamber mechanism. A guide roller is rotatably connected to the second frame.

[0008] Furthermore, the structures of the second and third transmission mechanisms are the same as those of the first transmission mechanism.

[0009] With the above technical solution, the first gear and the second pulley have the same module and number of teeth. When the first gear and the first pulley rotate, the second gear and the second pulley will be driven by the first pulley to rotate in the opposite direction at the same speed. The second transmission mechanism and the third transmission mechanism also have the same effect.

[0010] Furthermore, the winding mechanism includes a winding motor fixed to the first frame, a rotating shaft fixed to the output end of the winding motor, a third synchronous pulley fixed to the outside of the rotating shaft, the third synchronous pulley meshing with the first synchronous belt, a winding roller fixed to the top end of the rotating shaft, and a protective film roll fixed to the outside of the winding roller.

[0011] With the above technical solution, the winding motor is a servo motor. When the winding motor rotates, it can drive the rotating shaft, the third synchronous pulley and the winding roller to rotate, so that the winding roller can wind the protective film onto the protective film roll.

[0012] Furthermore, the structure of the unwinding mechanism is the same as that of the winding mechanism. Multiple enzyme reagent tablets are attached to one side of the test strip roll. The conveying mechanism includes a drive motor fixed on the first frame. A fourth synchronous pulley is fixed on the output shaft of the drive motor. A conveying roller is fixed at the top of the output shaft of the drive motor. A squeezing roller is attached to one side of the conveying roller. The squeezing roller is rotatably connected to the second frame.

[0013] Through the above technical solution, the test strip roll is formed by winding a strip of test paper and a strip of protective film pasted on the test paper. The protective film can effectively protect the enzyme reagent tablet from contact with air. When the unwinding assembly rotates, it can cause the test strip roll to rotate and release the strip of test paper. The test paper passes between the conveying roller and the squeezing roller. The conveying roller and the squeezing roller can guide the test paper and provide auxiliary power. The other end of the protective film passes around the squeezing roller and the guide roller and connects to the protective film roll, so that the device can unwind the test paper and rewind the protective film.

[0014] Furthermore, the color developing paper roll conveying mechanism includes another set of winding mechanism, unwinding mechanism and conveying mechanism, and the winding mechanism, unwinding mechanism and conveying mechanism of the color developing paper roll conveying mechanism are respectively engaged with the first transmission mechanism, the second transmission mechanism and the third transmission mechanism.

[0015] Through the above technical solution, the structure of the color development paper roll conveying mechanism is similar to that of the winding mechanism, unwinding mechanism and conveying mechanism, and the directions are opposite. It provides kinetic energy through the first transmission mechanism, the second transmission mechanism and the third transmission mechanism, which effectively reduces the number of servo motors used. The tablets on the test paper roll in the color development paper roll conveying mechanism are substrate tablets. The substrate can be acetylcholinesterase substrate. When the substrate tablets come into contact with the enzyme reagent tablets in a moist state, they can react with the enzyme reagent tablets and turn blue.

[0016] Furthermore, the base mechanism includes a base body fixed to one end of the first frame, an air pump is installed inside the base body, two slots are opened on the base body, a servo guide rail is fixed to the top of the base body, a mounting bracket is slidably connected to the servo guide rail, two miniature vacuum generators are fixed on the mounting bracket, and the miniature vacuum generators are connected to the air pump through an air passage.

[0017] Through the above technical solution, the servo guide rail can drive the mounting bracket to move, and the air pump can supply air to the miniature vacuum generator and the first and second cylinder mechanisms.

[0018] Furthermore, the first cylinder mechanism includes a fixed frame fixed on the mounting bracket, a first cylinder body fixed on the fixed frame, a guide frame fixed on the first cylinder body, a pressure plate connected to the output end of the first cylinder body, a vacuum suction cup fixed to the other end of the pressure plate, the vacuum suction cup being connected to a micro vacuum generator via an air passage, a sliding hole being provided on the guide frame, a guide rod being welded and fixed on the pressure plate, the guide rod being slidably connected to the sliding hole, a cutter being fixed to one end of the pressure plate, the second cylinder mechanism having the same structure as the first cylinder mechanism but facing opposite directions, the cutter of the second cylinder mechanism being slightly offset from the cutter of the first cylinder mechanism.

[0019] Through the above technical solution, the guide frame and guide rod can limit the movement direction of the pressure plate when the first cylinder body extends or retracts, thereby ensuring that the pressure plate can be displaced in the specified direction and reducing the error of the pressure plate in the movement direction. The vacuum suction cup can adsorb the test paper. The first cylinder mechanism and the second cylinder mechanism can respectively adsorb the enzyme reagent test paper and the substrate test paper, and pull the test paper out a certain distance through the servo guide rail and the mounting frame. When the first cylinder mechanism and the second cylinder mechanism extend, the two test papers are pressed together, and at the same time, the cutter will cut the test paper, thereby separating the part containing the reagent tablet and the substrate tablet. Since the reagent tablet and the substrate tablet are both in a dry state at this time, no reaction will occur when the two are attached.

[0020] Furthermore, the housing is fixed to the base body, the housing has an installation groove, and the housing is made of heat-insulating material.

[0021] With the above technical solution, after the first cylinder mechanism and the second cylinder mechanism remove the test strip segment, the first cylinder mechanism and the second cylinder mechanism retract, the two test strips separate, and the servo guide rail and the mounting bracket drive the first cylinder mechanism and the second cylinder mechanism and the test strip segment adsorbed on the cylinder mechanism to move into the housing. At this time, the electric lifting door will close, and the small air conditioner can ensure that the internal space of the housing is kept at a constant temperature, thereby providing relatively stable reagent reaction conditions.

[0022] Furthermore, the extraction spraying mechanism includes a connecting column welded and fixed to the shell, a stirring tank welded and fixed to the top of the connecting column, a cover sealed to the top of the stirring tank, and a stirring motor fixed to the top of the cover.

[0023] With the above technical solution, the stirring shaft of the stirring motor extends into the stirring tank through the cover, and stirring blades are fixed on the stirring shaft. When it is necessary to test fruits and vegetables for pesticide residues, the staff can open the cover and put the fruit and vegetable samples and pesticide residue extractant into the stirring tank, and then use the stirring motor to thoroughly stir them.

[0024] Furthermore, a filter is sealed to the water outlet of the housing, a micro water pump is sealed to the other end of the filter, a delivery pipe is sealed to the output end of the micro water pump, and a nozzle is sealed to the end of the delivery pipe.

[0025] Through the above technical solution, the miniature water pump can deliver the mixed test liquid to the nozzle and spray it out through the delivery pipe. When the first cylinder mechanism moves into the housing and retracts, the nozzle aligns with the substrate tablet on the first cylinder mechanism. Therefore, the test liquid sprayed by the nozzle can wet the substrate tablet. After the substrate tablet is wetted, the first and second cylinder mechanisms extend, and the tablets on both sides adhere to each other for reaction. After a period of reaction, the first and second cylinder mechanisms retract. The industrial control computer can effectively ensure that each reaction is successful. The reaction time is the same for both sides. After the two tablets separate, if the pesticide residue in the tested fruits and vegetables is low or nonexistent, the cholinesterase in the enzyme reagent tablet will decompose the substrate. The decomposition product reacts with the chromogenic agent in the substrate, and the test strip turns dark blue. If the pesticide residue exceeds the standard, the organophosphates or carbamates in the pesticide will inhibit the activity of cholinesterase, resulting in an inhibited color reaction. In this case, the test strip will turn colorless or light blue. The wide color gamut camera can take pictures of the tested test strip and transmit the image information to the industrial control computer. The artificial intelligence algorithm built into the industrial control computer analyzes the color of the test strip. This algorithm determines the concentration of pesticide residues in the fruit and vegetable samples based on the color intensity of the test strip, thus indicating whether the pesticide residues exceed the standard. Furthermore, the algorithm outputs various test results based on pesticide residue concentration, such as "pesticide residue not exceeding the standard," "pesticide residue exceeding the standard," and "pesticide residue severely exceeding the standard," transmitting these results directly to the industrial control computer. The computer displays the results on its screen, allowing staff to intuitively understand whether the pesticide residues in the samples exceed the standard. A supplementary light illuminates the test strip. During testing and imaging, the electric lifting door closes, and the servo guide rail is recessed and installed inside the mounting slot, ensuring unobstructed closure. The housing and the electric lifting door effectively isolate external light sources, preventing them from affecting the color accuracy when the wide color gamut camera captures the test strip.

[0026] The beneficial effects of this invention are as follows:

[0027] 1. This invention, through the setting of a transmission mechanism, a winding mechanism, an unwinding mechanism, a conveying mechanism, a color developing paper roll conveying mechanism, and a cylinder mechanism, realizes the automatic removal of film, unwinding, cutting, testing, and display of results of the test paper, reducing the manual operation process and improving the convenience of testing;

[0028] 2. By setting up a reaction testing chamber and an imaging mechanism, this invention enables the device to provide a constant-temperature reaction environment and ensures that the reaction time is equal for each reaction, reducing the influence of external light sources during imaging, thereby effectively ensuring the accuracy of artificial intelligence detection results.

[0039] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0040] like Figures 1-9As shown, a fruit and vegetable pesticide residue detection system utilizing artificial intelligence algorithms includes a first frame 1 and a reaction testing chamber mechanism 13. A first transmission mechanism 2 is rotatably connected to the first frame 1. The first transmission mechanism 2 includes a first gear 201 rotatably connected to the first frame 1. A first pulley 202 is coaxially fixed to the top of the first gear 201. A first synchronous belt 203 is meshed with the outside of the first pulley 202. A second gear 204 is meshed with one side of the first gear 201. The second gear 204 is rotatably connected to the first frame 1. A first synchronous belt 203 is coaxially fixed to the top of the second gear 204. The second pulley 205 has a second synchronous belt 206 externally meshing with it. The first frame 1 is rotatably connected to the second transmission mechanism 3 and the third transmission mechanism 4. The structure of the second transmission mechanism 3 and the third transmission mechanism 4 is the same as that of the first transmission mechanism 2. The first gear 201 and the second pulley 205 have the same module and number of teeth. When the first gear 201 and the first pulley 202 rotate, the second gear 204 and the second pulley 205 will be driven by the first pulley 202 to rotate in the opposite direction at the same speed. The second transmission mechanism 3 and the third transmission mechanism 4 have the same effect.

[0041] like Figures 1-4 As shown, a second frame 5 is fixed to the top of the first frame 1. A winding mechanism 6 is rotatably connected to the second frame 5. The winding mechanism 6 includes a winding motor 601 fixed to the first frame 1. A rotating shaft 602 is fixed to the output end of the winding motor 601. A third synchronous pulley 603 is fixed to the outside of the rotating shaft 602. The third synchronous pulley 603 meshes with the first synchronous belt 203. A winding roller 604 is fixed to the top of the rotating shaft 602. A protective film roll 605 is fixed to the outside of the winding roller 604. The winding motor 601 is a servo motor. When the winding motor 601 rotates, it can drive the rotating shaft 602, the third synchronous pulley 603, and the winding roller 604 to rotate, thereby causing the winding roller 604 to wind the protective film onto the protective film roll 605.

[0042] like Figures 1-4As shown, an unwinding mechanism 7 is rotatably connected to the second frame 5. The unwinding mechanism 7 includes an unwinding assembly 701, with a test strip roll 702 fixed to the top of the unwinding assembly 701. A conveying mechanism 8 is fixed to one end of the first frame 1. The structure of the unwinding mechanism 7 is the same as that of the winding mechanism 6. Multiple enzyme reagent tablets 703 are attached to one side of the test strip roll 702. The conveying mechanism 8 includes a drive motor 801 fixed to the first frame 1. A fourth synchronous pulley 802 is fixed to the output shaft of the drive motor 801. A conveying roller 803 is fixed to the top of the output shaft of the drive motor 801. A squeezing roller 804 is attached to one side of the conveying roller 803. Roller 804 is rotatably connected to the second frame 5. The test strip roll 702 is formed by winding a strip of test paper and a strip of protective film pasted on the test paper. The protective film can effectively protect the enzyme reagent tablet 703 from contact with air. When the unwinding assembly 701 rotates, it can make the test strip roll 702 rotate to release the strip of test paper. The test paper passes between the conveyor roller 803 and the squeeze roller 804. The conveyor roller 803 and the squeeze roller 804 can guide the test paper and provide auxiliary power. The other end of the protective film passes around the squeeze roller 804 and the guide roller 16 and connects to the protective film roll 605, so that the device can unwind the test paper and rewind the protective film.

[0043] like Figures 1-4 As shown, a colorimetric paper roll conveying mechanism 9 is provided on the second frame 5. The colorimetric paper roll conveying mechanism 9 includes another set of winding mechanism 6, unwinding mechanism 7 and conveying mechanism 8. The winding mechanism 6, unwinding mechanism 7 and conveying mechanism 8 of the colorimetric paper roll conveying mechanism 9 are respectively engaged with the first transmission mechanism 2, the second transmission mechanism 3 and the third transmission mechanism 4. The structure of the colorimetric paper roll conveying mechanism 9 is similar to that of the winding mechanism 6, the unwinding mechanism 7 and the conveying mechanism 8, and they are oriented opposite to each other. The kinetic energy is provided by the first transmission mechanism 2, the second transmission mechanism 3 and the third transmission mechanism 4, which effectively reduces the number of servo motors used. The tablets on the test paper roll 702 in the colorimetric paper roll conveying mechanism 9 are substrate tablets. The substrate can be an acetylcholinesterase substrate. When the substrate tablets are in a moist state and come into contact with the enzyme reagent tablets 703, they can react with the enzyme reagent tablets 703 and turn blue.

[0044] like Figure 1 and Figure 5As shown, a base mechanism 10 is fixed to one end of the first frame 1. The base mechanism 10 includes a base body 1001 fixed to one end of the first frame 1. An air pump is installed inside the base body 1001. Two slots 1002 are opened on the base body 1001. A servo guide rail 1003 is fixed to the top of the base body 1001. A mounting bracket 1004 is slidably connected to the servo guide rail 1003. Two miniature vacuum generators 1005 are fixed on the mounting bracket 1004. The miniature vacuum generators 1005 are connected to the air pump through an air circuit. The servo guide rail 1003 can drive the mounting bracket 1004 to move. The air pump can supply air to the miniature vacuum generators 1005 and the first cylinder mechanism 11 and the second cylinder mechanism 12.

[0045] like Figure 1 , Figure 5 and Figure 6 As shown, a first cylinder mechanism 11 and a second cylinder mechanism 12 are mounted on the base mechanism 10. The first cylinder mechanism 11 includes a fixing frame 1101 fixed to the mounting bracket 1004, a first cylinder body 1102 fixed to the fixing frame 1101, a guide frame 1103 fixed to the first cylinder body 1102, a pressure plate 1104 connected to the output end of the first cylinder body 1102, and a vacuum suction cup 1105 fixed to the other end of the pressure plate 1104. The vacuum suction cup 1105 is connected to the micro vacuum generator 1005 through an air passage. A sliding hole 1106 is provided on the guide frame 1103, and a guide rod 1107 is welded and fixed to the pressure plate 1104. The guide rod 1107 is slidably connected to the sliding hole 1106. A cutter 1108 is fixed to one end of the pressure plate 1104. The second cylinder mechanism 12 has the same structure as the first cylinder mechanism 11 but is oriented opposite to it. The cutter 1108 of the second cylinder mechanism 12... The cutter 1108 of the first cylinder mechanism 11 is slightly offset from the position of the cutter 1108. The guide frame 1103 and the guide rod 1107 can limit the movement direction of the pressure plate 1104 when the first cylinder body 1102 extends or retracts, thereby ensuring that the pressure plate 1104 can move in the specified direction and reducing the error of the pressure plate 1104 in the movement direction. The vacuum suction cup 1105 can adsorb the test paper. The first cylinder mechanism 11 and the second cylinder mechanism 12 can respectively adsorb the enzyme reagent test paper and the substrate test paper, and pull the test paper out a certain distance through the servo guide rail 1003 and the mounting frame 1004. When the first cylinder mechanism 11 and the second cylinder mechanism 12 extend, the two test papers are pressed together, and the cutter 1108 will cut the test paper, thereby separating the part containing the reagent tablet and the substrate tablet. Since the reagent tablet and the substrate tablet are both in a dry state at this time, no reaction will occur when the two are attached.

[0046] like Figure 1 and Figure 7As shown, a reaction test chamber mechanism 13 is fixed to the top of the conveying mechanism 8. The reaction test chamber mechanism 13 includes a housing 1301. An industrial control computer 1302 is fixed to the outside of the housing 1301. A small air conditioner 1303 is also embedded and fixed on the housing 1301. An electric lifting door 1304 is slidably connected to one end of the housing 1301. The housing 1301 is fixed to the base body 1001. An installation groove 1305 is provided on the housing 1301. The housing 1301 is made of heat-insulating material. After the first cylinder mechanism 11 and the second cylinder mechanism 12 remove the test strip segment, the first cylinder mechanism 11 and the second cylinder mechanism 12 retract, and the two test strips separate. The servo guide rail 1003 and the mounting bracket 1004 drive the first cylinder mechanism 11 and the second cylinder mechanism 12 and the test strip segment adsorbed on the cylinder mechanism to move into the housing 1301. At this time, the electric lifting door 1304 will close. The small air conditioner 1303 can ensure that the internal space of the housing 1301 is constant in temperature, thereby providing relatively stable reagent reaction conditions.

[0047] like Figure 1 and Figures 7-9As shown, a camera mechanism 14 is fixed inside the reaction test chamber mechanism 13. The camera mechanism 14 includes a mounting base plate 1401 fixed inside the housing 1301. A wide color gamut camera 1402 and a fill light 1403 are fixed on the mounting base plate 1401. An extraction spray mechanism 15 is fixed to the top of the reaction test chamber mechanism 13. A guide roller 16 is rotatably connected to the second frame 5. The extraction spray mechanism 15 includes a connecting column 1501 welded to the housing 1301. A stirring tank 1502 is welded to the top of the connecting column 1501. A cover 1503 is sealed to the top of the stirring tank 1502. A stirring motor 1504 is fixed to the top of the cover 1503. A filter is sealed to the water outlet of the housing 1301. 1505, the other end of the filter 1505 is sealed and connected to a miniature water pump 1506, the output end of the miniature water pump 1506 is sealed and connected to a delivery pipe 1507, the end of the delivery pipe 1507 is sealed and connected to a nozzle 1508, the stirring shaft of the stirring motor 1504 passes through the cover 1503 and extends into the stirring tank 1502, the stirring shaft is fixed with stirring blades, when it is necessary to test fruits and vegetables for pesticide residues, the staff can open the cover 1503 and put the fruit and vegetable samples and pesticide residue extractant into the stirring tank 1502, and then use the stirring motor 1504 to thoroughly stir them, the miniature water pump 1506 can transport the mixed test liquid to the nozzle 1508 through the delivery pipe 1507 and spray it out, when the first gas When cylinder mechanism 11 moves into housing 1301 and retracts, nozzle 1508 aligns with the substrate tablet on first cylinder mechanism 11. Therefore, the test liquid sprayed by nozzle 1508 wets the substrate tablet. After the substrate tablet is wetted, first cylinder mechanism 11 and second cylinder mechanism 12 extend, and the tablets on both sides adhere to each other for reaction. After a period of reaction, first cylinder mechanism 11 and second cylinder mechanism 12 retract. Industrial control computer 1302 effectively ensures that the reaction time is the same for each test. After the tablets on both sides separate, if the pesticide residue in the tested fruits and vegetables is low or absent, the cholinesterase in enzyme reagent tablet 703 will decompose the substrate. The decomposition product reacts with the chromogenic agent in the substrate, and the test strip turns dark blue. If the pesticide residue... If the pesticide residue exceeds the standard, components such as organophosphates or carbamates in the pesticide will inhibit the activity of cholinesterase, leading to an obstructed colorimetric reaction. In this case, the test strip will appear colorless or light blue. The wide color gamut camera 1402 can photograph the tested test strip and transmit the image information to the industrial control computer 1302. The artificial intelligence algorithm built into the industrial control computer 1302 analyzes the color of the test strip and can determine the concentration of pesticide residues in the fruit and vegetable samples based on the depth of the color development of the test strip, thereby determining whether the pesticide residues in the fruits and vegetables exceed the standard. In addition, the artificial intelligence algorithm built into the industrial control computer 1302 can also output multiple detection results based on the pesticide residue concentration, such as pesticide residue not exceeding the standard, pesticide residue exceeding the standard, and pesticide residue severely exceeding the standard.The test results are transmitted to the industrial control computer 1302, which displays the results directly on its screen. Staff can then visually assess whether pesticide residues in the sample exceed standards. The supplementary lighting 1403 provides illumination for the test strip. During testing and imaging, the electric lifting door 1304 closes. The servo guide rail 1003, recessed within the mounting slot 1305, does not obstruct the closing of the electric lifting door 1304. At this time, the housing 1301 and the electric lifting door 1304 effectively isolate external light sources, preventing external light from affecting color accuracy when the wide color gamut camera 1402 captures images of the test strip.

[0048] The working principle of this embodiment is as follows: When using this device to detect pesticide residues, the operator can place the fruit and vegetable samples and extract into the extraction spray mechanism 15, and then start the detection program through the industrial control computer 1302. At this time, the extraction spray mechanism 15 will stir the sample, and the unwinding mechanism 7 and the conveying mechanism 8 will release the enzyme reagent test strip and the substrate test strip. The winding mechanism 6 and the conveying mechanism 8 will cooperate with the cylinder mechanism to peel off the protective film of the test strip. The cylinder mechanism can cut and grasp the test strip, and then the cylinder mechanism will enter the reaction testing chamber mechanism 13. The extraction spraying mechanism 15 sprays the extract onto the substrate test paper. The cylinder mechanism causes the test papers on both sides to adhere and react. After a certain reaction time, the cylinder mechanism opens, and the imaging mechanism 14 takes a picture of the substrate test paper and transmits it to the industrial control computer 1302. The industrial control computer 1302 analyzes the color of the test paper through artificial intelligence algorithms to obtain the pesticide residue detection result. The industrial control computer 1302 can directly display the result on its screen, and the staff can intuitively understand whether the pesticide residue in the sample exceeds the standard and the extent of the exceedance by viewing the display screen of the industrial control computer 1302.

[0049] The above description is merely a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention.
