Abstract
Description
Technical Field
[0001] The invention relates to the technical field of agricultural Internet of Things applications, and in particular to an Internet of Things storage device for post-harvest physiological metabolism and pathological prevention of fresh pears. Background Art
[0002] Fresh pears will continue to undergo physiological metabolism after being picked, which leads to changes in quality and a shortened shelf life. Therefore, effective pathological prevention and storage management of fresh pears are the key to ensuring their quality and extending their shelf life. At present, controlled atmosphere fresh-keeping warehouses are the main technical means to achieve this goal. This storage technology effectively reduces the respiration and metabolic rate of fresh pears by precisely controlling the gas composition (including oxygen, carbon dioxide and nitrogen) as well as temperature and humidity in the warehouse, thereby extending its shelf life. Furthermore, by integrating Internet of Things technology, controlled atmosphere fresh-keeping warehouses can achieve more intelligent and automated management. Internet of Things technology enables managers to remotely monitor and adjust environmental parameters in the warehouse, realize real-time data collection and analysis, and optimize storage strategies. The integration of these technologies not only enhances control over the storage process, but also improves the preservation effect, reduces losses, and at the same time improves the energy efficiency and sustainability of the entire storage system.
[0003] During the storage process, fresh pears are usually stored on storage racks in a controlled atmosphere fresh-keeping warehouse. Although the controlled atmosphere fresh-keeping warehouse can adjust the storage environment well to extend the storage period of fresh pears, it cannot completely eliminate all factors that cause fresh pear lesions. Some fresh pears in the fresh-keeping warehouse may still develop lesions due to various factors. If the diseased fruits are not removed in time, the disease may be transmitted to other healthy fresh pears through contact or spores in the air, leading to the spread of the disease. At present, the storage monitoring of fresh pears usually relies on manual inspection, which has limited efficiency. Due to labor cost considerations, the inspection frequency may not be too high. This low-frequency inspection may result in diseased fruits not being discovered and handled in time, thereby increasing the risk of disease spread. Therefore, based on the above problems, an Internet of Things storage device for post-harvest physiological metabolism and pathological prevention of fresh pears is proposed. Summary of the invention

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. In the present invention, by setting the main body, the bearing module, the weighing sensor, the detection module and other structures, the main body can carry and store the bearing module, the weighing sensor, the detection module and the fresh pears. During the storage process, the fresh pears will be regularly inspected for diseases by the automated equipment. The equipment first drives the fresh pears to move to the bearing module, weighs and photographs the appearance, and compares it with the historical data to preliminarily determine whether there is an abnormality. Subsequently, the fresh pears are rotated by the gas transmission part, the extrusion part, the lifting part, the roller part and the turning part, and the surface of the fresh pears is further inspected by the touch rod of the pressure dividing part. The industrial camera The appearance of fresh pears is fully photographed, and the deformation information generated by the touch pressure of the touch rod is transmitted to the processing host for analysis, and finally it is determined whether the fresh pears are diseased. The fresh pear post-harvest storage equipment can automatically detect diseases on the stored fresh pears with the integrated Internet of Things technology to complete the pathological prevention of stored fresh pears. This solves the problem that the storage monitoring of fresh pears by existing fresh pear post-harvest storage equipment usually relies on manual inspection, which is generally inefficient and limited by labor costs. The inspection frequency is not high. This low-frequency inspection may result in diseased fruits not being discovered and handled in time, thereby increasing the risk of disease spread; 2. In the present invention, by setting the storage plate, driving part and transmission part, the power assembly of the driving part is controlled to operate first, so that the rotating column drives the toggle wheel to rotate, and the rotation of the toggle wheel toggle each insertion strip to move, thereby driving the transmission belt to move, which in turn drives all the toggle plates on the transmission belt to move in the outer baffle frame. At this time, the staff can place each fresh pear between each toggle plate of the storage plate at a fixed position, and the displacement of the toggle plate will drive the placed fresh pears to move on the shelf, which is convenient for the staff to quickly and labor-savingly place the fresh pears to be stored, and avoids the staff walking back and forth to place the fresh pears; 3. In the present invention, through the structures such as the discharge part, the storage channel shell and the bearing module, when the diseased fruit is detected, the equipment will start a series of operations to discharge it. First, the electric push rod is extended to push the transmission guide plate to move, so that the transmission guide plate is aligned with the through-port, and the pressure guide strip is displaced. At the same time, the pressure guide strip will drive the notch to move to the inside of the arc groove, so that the counterweight is aligned with the notch. At this time, the weight of the counterweight is pulled down to make the elastic resistance belt enter the arc groove, exposing the notch of the outer baffle frame, and the pressure guide strip will be inserted into the bearing module. After a series of transmissions, the front roller part moves down, the rear roller part moves up, and the touch rod of the pressure dividing part is further pushed outward, giving the diseased fruit multiple thrusts, so that it passes over the notch of the outer baffle frame and passes through the through-port, and is finally discharged from the discharge port through the transmission guide plate and falls into the storage channel shell for processing, so that the fresh pear post-harvest storage equipment can automatically discharge the diseased fruit after disease detection, avoiding the problem of disease spread due to failure to remove the diseased fruit in time.

The driving rear end of the electric push rod 44 is fixedly connected to the transmission guide plate 45 through a connecting block. The rear ends of the transmission guide plate 45 are symmetrically fixedly connected to the two sides of the rear end thereof with pressure guide strips 46 that pass through the through plate 42 and are located in the through opening 126. The pressure guide strips 46 pass through the supporting pieces of the counterweight 125. The upper part of the pressure guide strips 46 is provided with notches 47. The left plate surface of the front shell 41 is provided with a plurality of pressure guide strips 47 that are located on the left side of the transmission guide plate 45. The discharge port 48 is provided with a storage channel shell 7 fixedly connected to the left end face of the front shell 41 at the lower side of the discharge port 48. Through this arrangement, when a diseased fruit is detected, the device will start a series of operations to discharge it. First, the electric push rod 44 extends to push the transmission guide plate 45 to move, so that the transmission guide plate 45 is aligned with the through port 43, and pushes the pressure guide bar 46 to move. At the same time, the pressure guide bar 46 will drive the notch 47 to move to the inside of the arc groove 122, so that the counterweight 125 is aligned with the notch 47. At this time, the weight of the counterweight 125 is pulled down to make the elastic resistance The belt 124 enters the arc groove 122, exposing the gap of the outer baffle 123, and the pressure guide strip 46 is inserted into the bearing module 3. After a series of transmissions, the front roller 34 moves down, the rear roller 34 moves up, and the contact rod 555 of the pressure dividing part 55 is further pushed outward, giving the diseased fruit multiple thrusts, so that it passes over the gap of the outer baffle 123 and passes through the through hole 43, and finally is discharged from the discharge port 48 through the transmission guide plate 45 and falls into the storage channel shell 7 for processing, so that the fresh pear post-harvest storage equipment can automatically discharge the diseased fruit after disease detection;The electric push rod 44 is electrically connected to the processing host 9, and the processing host 9 can control the electric push rod 44 through this setting. The lower inner wall of the through hole 43 and the upper end surface of the frame plate 121 are arranged in the same plane. Through this setting, the diseased fruit can pass through the through hole 43 from the frame plate 121 without hindrance. The transmission guide plate 45 is arranged below the through hole 43. The spacing dimension between the notch 47 and the counterweight 125 is the same as the spacing dimension between the rear end of the transmission guide plate 45 and the through plate 42.

[0018] Workflow: The pathological prevention detection operation of the fresh pear storage device after harvesting by the Internet of Things is as follows: First, the electrical appliances in this scheme are all powered by external power. The data collected by the weighing sensor 2 and the industrial camera 54 in this scheme are all transmitted to the processing host 9 for processing, and then all electrical appliances are controlled and operated by the processing host 9; Second, the operation of the motor of the power component 133 can drive the gear and the gear ring to rotate. The rotation of the gear ring will cause the front rotating column 131 to rotate. Due to the meshing of the sprocket and the chain belt, the rear rotating column 131 rotates with the front rotating column 131; Note 3: The operation of the motor of the rotating part 53 can drive the roller to rotate; Note 4: The weighing sensor 2 weighs the fresh pears on the upper side of the carrying module 3, and the weight data of the carrying module 3 will be removed at the processing host 9 to obtain the accurate weight of the fresh pears; Fresh pear rack storage operation: First, the power component 133 is controlled to operate, so that the rotating column 131 drives the toggle wheel 132 to rotate, and the rotation of the toggle wheel 132 toggle each insertion strip 142 to move, thereby driving the transmission belt 141 to move, which in turn drives all the toggle plates 143 on the transmission belt 141 to move on the outer baffle frame 123 The staff can place the fresh pears between the paddles 143 of the storage plate 12 at a fixed position. The displacement of the paddles 143 will drive the fresh pears to move on the shelf plate 121 (the fresh pears move over a large range and will not be damaged by the protection of the soft pads 128), which makes it convenient for the staff to swing the fresh pears to be stored, thereby performing the swing operation. During the swing process, the fresh pears will pass through the carrying module 3. When the fresh pears are on the upper side of the carrying module 3 (the guidance of the concave guide groove on the base shell 31 is conducive to the displacement of the fresh pears to the upper side of the carrying module 3), the weighing sensor 2 can The fresh pears are weighed, and at the same time, the industrial camera 54 identifies the number plates 144 of the dial plates 143 on both sides of the fresh pears, and takes photos of the appearance of the fresh pears, and then sends the weighing information, appearance information and identification information to the processing host 9 to file the fresh pears being weighed. The above operations complete the file building operation for each fresh pear; finally, the storage chamber of the atmosphere-controlled fresh-keeping warehouse 8 is closed, and the temperature, humidity and gas environment in the storage chamber of the atmosphere-controlled fresh-keeping warehouse 8 are adjusted by the processing host 9 to keep the environment suitable for the storage of fresh pears. The above steps complete the storage operation of the fresh pears on the shelf;Automatic detection of diseased fruit: During the storage of fresh pears, diseased fruit detection will be performed regularly according to the program setting. First, the driving unit 13 is controlled to operate, driving the transmission unit 14 to move each fresh pear on the storage plate 12, so that each fresh pear is moved to the upper side of the carrying module 3 one by one, and the fresh pear is weighed by the weighing sensor 2. At the same time, the industrial camera 54 will take a picture of the appearance of the fresh pear. The industrial camera 54 recognizes the number plates 144 on both sides to determine which fresh pear the weighed fresh pear is from the archive. Then, the processing host 9 retrieves the historical weight data and compares it with the current weighing data to detect whether the fresh pear has abnormal disease. The weight phenomenon is detected, and then the historical appearance information is retrieved and compared with the appearance information of this shooting to detect whether plaques appear. If plaques appear, the graphics are compared with the diseased plaque illustration stored in the processing host 9 to make a preliminary judgment on the diseased fruit. Through the above operation, each stored fresh pear is tested for appearance and weight, and the test data is updated to the file of the fresh pear for use in the next batch of tests, and then further tests are carried out. First, the weighing data collection of each weighing sensor 2 is stopped, and then the filling and suction dual-purpose air pump 61 is controlled to run, and the inside of each cover 64 is cleaned through the distribution pipe 62 and the shunt pipe 63. Inflation, under the influence of gas push, the piston 523 in each squeezing part 52 drives the extension rod 522 and the pressing block 524 to move downward, so that the downwardly moved pressing block 524 enters the sink 312 to squeeze the circular airbag 321, so that the gas in the circular airbag 321 enters the diverter shell 323 through the gas delivery pipe 322, and then the gas is evenly transported to the rectangular airbags 324 on both sides through the diversion of the diverter shell 323, so that the rectangular airbags 324 on both sides expand and expand to push up the rollers 34 on both sides, and the upward movement of the rollers 34 will lift the fresh pears on the upper side of the carrying module 3, so that the upper surface of the fresh pears is aligned with the rotation of the turning part 53. The roller contacts, at this time, the pre-activated turning part 53 can drive the rotation of the roller through the motor to drive the fresh pear held by the roller part 34 to rotate, so as to complete the rotation of the fresh pear; at the same time, the gas in the cover shell 64 can also be transported to the sleeve shell 552 through the gas transmission shell 551, and as the gas in the sleeve shell 552 increases, the feeler rods 555 in each inner shell 553 can be pushed outward, so that the feeler rods 555 are tilted downward and contact the surface of the fresh pear (the lower end of the feeler rod 555 is an arc head, and its contact does not cause damage to normal fresh pears), and as the fresh pears rotate, each feeler rod 555 will sweep across the surface of the fresh pear (such as; Fig.23As shown), at this time, the industrial camera 54 can take a comprehensive appearance photo of the fresh pear and comprehensively detect whether there are plaques. On the other hand, if there are some areas of the fresh pear that are too soft, the touch rod 555 will cause deformation of the position when it scans over, and whether the position overlaps with the plaque. All of the above will be photographed and identified. The above information will be transmitted to the processing host 9 for analysis and processing to further determine whether the fresh pear is abnormal. Finally, the multiple judgment results are combined to determine whether the fresh pear is diseased. If not, the dual-purpose air pump 61 is controlled to evacuate air to shrink and reset the squeezing part 52, and reset the pressure dividing part 55. Then the fresh pear and the roller part 34 will move downward to squeeze the rectangular air bag 324, so that the gas in the rectangular air bag 324 passes through the diverter shell 3 23 and the air delivery pipe 322 flow back into the circular airbag 321, and the circular airbag 321 is re-expanded and unfolded through the reset operation, so that the roller part 34 is reset back into the base shell 31, and the fresh pear falls on the upper end surface of the base shell 31 again, and the reset operation is completed. At this time, the next fresh pear can be detected, and the automatic detection operation of diseased fruit is completed through the above steps; the fresh pear post-harvest storage equipment cooperates with the integrated Internet of Things technology to automatically detect diseases on the stored fresh pears, which solves the problem that the storage monitoring of fresh pears by the existing fresh pear post-harvest storage equipment usually relies on manual inspection, the efficiency is generally average, and the inspection frequency is not high due to the limited labor cost. Such low-frequency inspection may result in the diseased fruit not being discovered and handled in time, thereby increasing the risk of disease spread;Diseased fruit discharge operation: When the detection operation detects a diseased fruit, the electric push rod 44 corresponding to the diseased fruit is controlled to extend, and the transmission guide plate 45 is pushed to move toward the through-port 43 corresponding to the diseased fruit. The displacement of the transmission guide plate 45 makes the rear end of the transmission guide plate 45 fit with the through-plate 42, and aligns the left end with the discharge port 48, so as to prepare for the subsequent discharge of the diseased fruit. At the same time, the pressure guide strips 46 on both sides are pushed to move. The displacement of the pressure guide strips 46, on the one hand, drives the notch 47 to move to the inside of the arc groove 122, so that the arc groove 122 is aligned with the counterweight 125. At this time, the weight of the counterweight 125 is pulled down, which drives the elastic resistance belt 124 to deform and displace downward and enter the arc groove 122, so that the outer retaining frame 123 exposes the notch, so that the elastic resistance belt 124 no longer restricts the passage of the diseased fruit. On the other hand, the rear end of the pressure guide strip 46 passes through the insertion port 315, and the transmission block is pressed against the transmission block through its inclined chamfer. 35 is pressed downward, thereby driving the front roller portion 34 to move downward, squeezing the front rectangular airbag 324, and the gas in the front rectangular airbag 324 is transmitted to the rear rectangular airbag 324 through the diverter shell 323 (because it is still in the detection process, the circular airbag 321 is still pressed by the pressure block 524 at this time and cannot receive the gas of the front rectangular airbag 324), so that the rear rectangular airbag 324 is further expanded and unfolded, and the rear roller portion 34 is further moved upward. At this time, the front roller portion 34 no longer supports the front part of the diseased fruit, so that the front part of the diseased fruit moves downward. At the same time, the further upward push of the rear roller portion 34 on the rear part of the diseased fruit will give the diseased fruit a forward thrust, and the change in the distance between the diseased fruit and the pressure dividing portion 55 will enable the touch rod 555 of the pressure dividing portion 55 to be further pushed downward obliquely, thereby giving the diseased fruit an oblique downward forward thrust (such as; Fig.24 As shown by the conduction arrows, at this time, the diseased fruit can pass through the gap of the outer baffle 123 and pass through the through-port 43 through the influence of multiple thrusts, and enter the transmission guide plate 45. Then, the diseased fruit can be discharged from the discharge port 48 and fall into the storage channel shell 7 for storage through the transmission guide of the transmission guide plate 45, so that the staff can handle it. After the diseased fruit is taken out, it is only necessary to reset and contract the extended electric push rod 44 to reset each driven mechanism. The diseased fruit discharge operation is completed through the above steps, so that the fresh pear post-harvest storage equipment can automatically discharge the diseased fruit after the disease detection, avoiding the problem of disease spread due to the failure to remove the diseased fruit in time.
