Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of crop seed treatment, in particular to a high-frequency pulse treatment device and method for crop seeds. BACKGROUND

[0002] The main purpose of the crop seed treatment device is to improve seed quality and enhance crop production performance. The specific effects include: increasing germination rate and germination vigor, enabling more seeds to successfully germinate and germinate more evenly and quickly, enhancing seedling vitality, making the seedlings grown from treated seeds stronger and having more developed root systems and stronger disease and pest resistance, improving stress resistance, enhancing the tolerance of seeds or seedlings to adverse environments such as drought, salinity, and low temperature, promoting growth and development, accelerating crop growth, and possibly improving yield and quality, and replacing chemical treatment, reducing dependence on chemical agents such as fungicides and growth regulators, and being more environmentally friendly and safe.

[0003] Common crop seed treatment devices mostly use a single physical treatment method, such as using only low-frequency electromagnetic fields, or ozone fumigation alone, or providing only constant light irradiation, lacking a multi-factor synergistic mechanism, resulting in limited treatment effects and difficulty in significantly improving seed germination rate and seedling growth vigor. Due to the single mechanism of action, the seed's water absorption, sterilization effect, and physiological activity cannot be improved simultaneously, and the treated seeds still have problems such as uneven emergence, slow germination, and poor stress resistance in actual sowing, affecting agricultural production efficiency. At the same time, such devices generally have low intelligence, simple operation interfaces, and require manual input of parameters, so users need to have certain professional knowledge to correctly configure key parameters such as pulse frequency, voltage intensity, treatment time, light duration, and ozone concentration, which has a high operation threshold and is difficult for ordinary farmers to master, leading to errors such as excessive voltage damaging the embryo, excessive treatment time inhibiting germination, and excessive ozone concentration causing oxidative damage, affecting treatment safety and stability. In addition, most devices do not have data storage and calling functions, and parameters need to be reset for each treatment, which not only reduces efficiency but also leads to inconsistent treatment processes between different batches, lacks repeatability and standardization, and is difficult to meet the modern agricultural demand for efficient, precise, and traceable seed treatment. SUMMARY

[0004] To overcome the shortcomings of the prior art, the present application provides a high-frequency pulse treatment device and method for crop seeds, which integrates electric field, ozone, and light synergistic treatment, intelligently matches parameters, one-key starts, and remotely monitors to improve germination rate and uniformity, realizes efficient, precise, and intelligent seed treatment, and solves the problems of single function, low intelligence, reliance on manual parameter setting, errors, poor treatment effect, lack of synergistic effect and data management, and difficulty in achieving efficient, stable, and traceable standardized operation of common seed treatment devices.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a high-frequency pulse processing device and method for crop seeds, comprising a conveyor frame; further comprising electric rollers rotatably mounted at both ends of the conveyor frame, a variable frequency speed control motor mounted on the front side of the conveyor frame, a support roller rotatably connected to the inner side of the conveyor frame, a conveyor belt sleeved on the surface of the two electric rollers, a closed cover set at the upper end of the conveyor frame, two hanging rods mounted on the closed cover, a leveling component mounted on the closed cover, and an automatic door opening and closing component mounted at the openings at the left and right ends of the closed cover; The lower ends of the two booms are equipped with upper electrode plates, and the lower electrode plates are installed on the conveyor frame. A high-frequency pulse emission device is installed on the front side of the conveyor frame. The enclosure is an inverted U-shaped tunnel structure. The enclosure is fastened to the top of the conveyor frame. The upper electrode plates are horizontally suspended below the booms through insulating connectors and are located directly above the conveyor belt. The lower electrode plates are located directly below the conveyor belt and are positioned opposite to the upper electrode plates. The lower electrode plates and the upper electrode plates are respectively connected to the positive and negative output terminals of the high-frequency pulse emission device to form a vertical high-frequency electric field processing area. A variable frequency speed control motor drives one of the electric rollers. The support rollers are spaced below the conveyor belt to support it. Multiple observation windows are opened on both sides of the enclosed cover. Two plant grow lights are installed on the curved wall at the top of the enclosed cover. An ozone generator is installed on the inner wall at one end of the enclosed cover. A control box is installed on the rear end of the conveyor frame.

[0006] Furthermore, the leveling assembly includes an electric push rod mounted on the upper surface of the enclosure and a leveling scraper mounted on the output end of the electric push rod.

[0007] Furthermore, the automatic door opening and closing assembly includes mounting frames installed at both ends of the enclosure, an electric push rod II installed on the upper surface of the mounting frames, a cavity block installed at the output end of the electric push rod II, a sealing airbag sleeved on the surface of the cavity block, and an air pump installed on the surface of the cavity block. The cavity block and the sealing airbag are interconnected.

[0008] Furthermore, the conveyor belt is equipped with vertical side guards on both sides, and the high-frequency pulse transmitter outputs a frequency of 5kHz to 1MHz and a voltage of 5kV to 30kV, which can generate a high-intensity alternating electric field.

[0009] Furthermore, the plant grow light is a full-spectrum LED light strip with a light emission wavelength covering 400–780 nm. The light intensity of the plant grow light is adjustable to simulate the natural sunlight environment and enhance the physiological activity of seeds in conjunction with high-frequency pulse effects.

[0010] Furthermore, the ozone generator produces ozone in g / h, and its outlet is connected to a microporous diffuser tube to uniformly release low-concentration ozone ≤0.1 ppm, which is used to sterilize and disinfect the seed surface and stimulate the germination enzyme system.

[0011] Furthermore, the control box integrates a PLC controller and a touch screen human-machine interface, allowing users to select different crop varieties. The system automatically matches the corresponding processing parameter combinations based on the preset database, including pulse frequency, voltage, processing time, ozone concentration, light intensity, and conveying speed. The control box is also equipped with a wireless communication module that supports Wi-Fi connectivity.

[0012] Furthermore, the variable frequency speed control motor is controlled by a frequency converter, and the conveyor belt speed can be steplessly adjusted within the range of 0.05 to 0.5 m / min to adapt to the processing time requirements of different seeds.

[0013] Furthermore, the method for seed treatment using this device includes the following steps: Step 1: Select the crop variety to be processed through the human-machine interface of the control box. The system will automatically call up the processing parameter package corresponding to the selected variety. The parameter package includes high-frequency pulse frequency, voltage amplitude, processing time, ozone concentration, light intensity of plant supplemental lighting, and conveyor belt running speed. Step 2: Seeds fall from the outlet of the external discharge machine into the conveyor belt. The electric push rod drives the flat scraper to spread the seeds into a single layer. The variable frequency speed control motor starts and drives the conveyor belt to run at a constant speed, so that the seeds enter the high-frequency electric field treatment area inside the closed cover. Step 3: The electric push rod drives the cavity block to close the hatch, and the air pump starts to inflate the sealing airbag, making the two ends of the enclosure airtight.

[0014] Step 4: The high-frequency pulse emission device is activated, forming a vertical high-frequency pulse electric field between the upper and lower plates, which acts on the seeds. At the same time, the ozone generator releases low-concentration ozone, and the plant grow lights provide full-spectrum illumination. The electric field, gas, and light environment are treated in a triple synergistic manner. Step 5: After processing, the conveyor belt transports the seeds to the outlet, the electric push rod drives the hatch to open, and the seeds are automatically discharged; the control box records the variety, parameters, time and other data of this processing and uploads them to the local or cloud database to complete the batch processing process.

[0015] Compared with the prior art, the technical solution of this application has the following beneficial effects: 1. This method integrates three physical treatment methods—high-frequency pulsed electric field, ozone treatment, and full-spectrum LED supplemental lighting—into a single enclosed treatment space, forming a multi-factor synergistic mechanism. The high-frequency pulsed emission device generates a high-intensity alternating electric field of 5kV to 30kV between the upper and lower plates, inducing reversible electroporation of seed cell membranes and enhancing their water absorption capacity and metabolic activity. Simultaneously, the ozone generator releases low-concentration ozone (≤0.1 ppm), effectively sterilizing the seed surface and stimulating the endogenous enzyme system. The plant supplemental lighting provides full-spectrum illumination covering 400–780nm, simulating the natural sunlight environment and activating phytochromes and photosynthetic physiological processes. The synergistic effect of these three treatment methods significantly improves seed germination rate, germination potential, and seedling uniformity, with treatment effects far superior to single physical treatment methods. 2. Equipped with an integrated PLC controller and touch screen human-machine interface, the control box allows users to directly select crop varieties (such as corn, rice, soybeans, etc.) through the interface. The system automatically calls the preset optimal processing parameter package, including high-frequency pulse frequency, voltage amplitude, processing time, ozone concentration, light intensity, and conveying speed, to achieve "one-click start and intelligent operation". The control box is also equipped with a Wi-Fi communication module, which supports remote monitoring of equipment status, receiving fault alarms, and uploading processing data to the cloud database, facilitating production management and quality traceability. This intelligent design significantly reduces the operating threshold, avoids human error in setting, and improves the standardization and informatization level of the equipment, meeting the needs of modern agriculture for smart agricultural equipment. 3. The structural design fully considers operational safety and environmental sealing. Automatic doors driven by electric push rods are installed at both ends of the enclosure. After the doors are closed, the air pump inflates the sealing airbags fitted on the surface of the cavity block, causing them to expand and deform and fit tightly against the end face of the enclosure, forming an elastic sealing structure. This effectively prevents ozone leakage during the process and ensures the health and safety of operators. At the same time, the system is equipped with a safety interlock mechanism: the high-frequency pulse emission equipment cannot be started when the doors are not fully closed, eliminating the risk of high-voltage electric field leakage. Observation windows are installed on both sides of the enclosure to facilitate real-time monitoring of the internal operating status and timely detection of abnormalities.

[0018] This device uses a purely physical method for seed pretreatment, without using any chemical agents, generating no high temperatures, and causing no mechanical damage to the seeds. It is green and environmentally friendly, and meets the requirements of organic agriculture and sustainable development.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figures 1-7 The high-frequency pulse processing device and method for crop seeds in this embodiment includes a conveyor frame 1; it also includes electric rollers 2 rotatably installed at both ends of the conveyor frame 1, a variable frequency speed control motor 3 installed on the front side of the conveyor frame 1, a support roller 5 rotatably connected to the inner side of the conveyor frame 1, a conveyor belt 4 sleeved on the surface of the two electric rollers 2, a closed cover 7 set at the upper end of the conveyor frame 1, two hanging rods 8 installed on the closed cover 7, a leveling component installed on the closed cover 7, and an automatic door opening and closing component installed at the openings at the left and right ends of the closed cover 7. A variable frequency speed control motor 3 drives and connects to one of the electric rollers 2. The support rollers 5 are spaced below the conveyor belt 4 to support the conveyor belt 4. Multiple observation windows 10 are opened on both sides of the enclosed cover 7. Two plant supplement lights 11 are installed on the curved wall at the top of the enclosed cover 7. An ozone generator 13 is installed on the inner side wall at one end of the enclosed cover 7. A control box 6 is installed on the rear end face of the conveyor frame 1.

[0021] In this embodiment, a high-frequency pulsed electric field (5kV~30kV), low-concentration ozone (≤0.1 ppm), and full-spectrum LED illumination (400~780nm) are integrated into a sealed chamber to achieve multi-factor synergistic treatment of electric field activation, ozone sterilization, and light activation, significantly improving seed germination rate and seedling uniformity. At the same time, it is equipped with an intelligent control system that supports variety selection, automatic parameter matching, "one-click start," and remote monitoring, achieving efficient, precise, and intelligent seed treatment.

[0022] Please see Figures 1-7 In this embodiment, to allow seeds to receive multiple stimuli simultaneously in a sealed chamber, which is more effective than using only one method and can significantly improve germination speed and seedling quality, upper electrode plates 9 are installed at the lower ends of the two suspension rods 8, and lower electrode plates 21 are installed on the conveyor frame 1. A high-frequency pulse emission device 12 is installed on the front side of the conveyor frame 1. The sealing cover 7 has an inverted U-shaped tunnel structure and is fastened to the top of the conveyor frame 1. The upper electrode plate 9 is horizontally suspended below the suspension rods 8 through insulating connectors, located directly above the conveyor belt 4, and the lower electrode plate 21 is positioned on the conveyor belt 4. Directly below, the lower electrode plate 21 and the upper electrode plate 9 are positioned opposite each other. The lower electrode plate 21 and the upper electrode plate 9 are respectively connected to the positive and negative output terminals of the high-frequency pulse emission device 12, forming a high-frequency electric field treatment area in the vertical direction. The plant supplement light 11 is a full-spectrum LED light strip with a light emission wavelength covering 400-780nm. The light intensity of the plant supplement light 11 is adjustable and is used to simulate the natural sunlight environment. It works in conjunction with the high-frequency pulse effect to enhance the physiological activity of seeds. The ozone generator 13 has an ozone output of g / h. The outlet is connected to a microporous diffuser tube to uniformly release low-concentration ozone ≤0.1 ppm, which is used to sterilize and disinfect the seed surface and stimulate the germination enzyme system.

[0023] In this embodiment, the upper electrode plate 9 and the lower electrode plate 21 are arranged opposite to each other and are respectively installed on the hanging rod 8 and the conveyor frame 1, connected to the high-frequency pulse emission device 12 to form a high-frequency electric field in the vertical direction. This field acts on the seeds, enhancing cell membrane permeability, promoting water absorption and metabolic activation. The high-frequency pulse emission device 12 provides an adjustable high-voltage alternating electric field to ensure that the treatment intensity is adapted to different seed types. The plant supplemental light 11 uses a full-spectrum LED light strip, covering a wavelength range of 400 to 780 nanometers. The light intensity is adjustable, simulating a natural sunlight environment, activating the photosensitive pigments and physiological reactions inside the seeds, and enhancing germination potential in conjunction with the electric field. The ozone generator 13 generates ozone at a rate of 10 grams per hour, which is uniformly released through a microporous diffuser tube with a concentration controlled below 0.1 ppm. This effectively sterilizes the seed surface and slightly stimulates the enzyme system to promote germination. The conveyor belt 4 smoothly transports the seeds, allowing them to continuously pass through the treatment area, ensuring that each seed undergoes a complete treatment process. The control box 6 integrates an operating interface to set parameters and start / stop the equipment, facilitating user management of the entire treatment process.

[0024] It should be noted that the leveling component includes an electric push rod 14 mounted on the upper surface of the enclosure 7 and a leveling scraper 15 mounted on the output end of the electric push rod 14. The automatic door opening and closing component includes mounting frames 16 mounted at both ends of the enclosure 7, an electric push rod 17 mounted on the upper surface of the mounting frame 16, a cavity block 18 mounted on the output end of the electric push rod 17, a sealing airbag 19 sleeved on the surface of the cavity block 18, and an air pump 20 mounted on the surface of the cavity block 18. The cavity block 18 and the sealing airbag 19 are interconnected. The conveyor belt 4 has vertical side guards on both sides. The high-frequency pulse transmitting device 12 has an output frequency of 5kHz to 1MHz and a voltage of 5kV to 30kV, which can generate a high-intensity alternating electric field. The variable frequency speed control motor 3 is controlled by a frequency converter, and the running speed of the conveyor belt 4 can be 0.05 to 0.5. The speed is infinitely adjustable within the range of m / min to adapt to the processing time requirements of different seeds. The leveling scraper 15 moves up and down under the drive of the electric push rod 14 to flatten the seeds falling into the conveyor belt 4, avoid seed stacking, ensure uniform electric field and light effect, and improve processing consistency. The electric push rod 14 responds to the control signal to realize the automatic lifting and lowering of the scraper, improving the degree of automation of the operation. The electric push rod 27 pushes the cavity block 18 to drive the door to close, realizing the automatic opening and closing of both ends of the sealing cover 7, reducing manual intervention and improving operating efficiency. The cavity block 18 is interconnected with the sealing airbag 19. After the air pump 20 inflates the sealing airbag 19, the airbag expands and fits tightly against the end face of the chamber to form an effective seal, preventing ozone leakage and ensuring the safety of the operating environment. At the same time, it maintains a stable processing atmosphere in the chamber. Vertical baffles are provided on both sides of the conveyor belt 4 to effectively prevent seeds from spilling during operation, keep the equipment clean and the materials intact. The high-frequency pulse transmitter 12 outputs a frequency of 5 With frequencies ranging from kHz to 1 MHz and voltages ranging from 5 kV to 30 kV, it can generate a high-intensity alternating electric field, suitable for cell activation treatment of various seeds. The variable frequency speed control motor 3 adjusts the speed through a frequency converter, so that the running speed of the conveyor belt 4 is steplessly adjustable between 0.05 and 0.5 meters per minute, adapting to the processing time required for different seeds and realizing flexible process control.

[0025] Please see Figures 1-7 In this embodiment, for ease of operation, the system automatically adjusts the corresponding parameters based on the selected crop. It can also be remotely viewed and operated via mobile phone, making it simple to use and easy to manage, suitable for modern smart agriculture. The control box 6 in this embodiment integrates a PLC controller and a touch screen human-machine interface, supporting users to select different crop varieties. The system automatically matches the corresponding processing parameter combination according to the preset database, including pulse frequency, voltage, processing time, ozone concentration, light intensity, and conveying speed. The control box 6 is also equipped with a wireless communication module, supporting Wi-Fi connection.

[0026] In this embodiment, the control box 6 integrates a touch screen human-machine interface, allowing users to directly select crop varieties via the screen. The operation is intuitive and convenient. The built-in controller automatically calls preset processing parameter combinations based on the selected variety, including pulse frequency, voltage, processing time, ozone concentration, light intensity, and conveying speed, enabling one-button start-up, avoiding manual setting errors, and improving processing accuracy and repeatability. The wireless communication module supports Wi-Fi connectivity, which can upload the equipment's operating status to a mobile terminal, supporting remote start / stop, fault alarms, and data viewing. This facilitates centralized management of multiple devices and production traceability, improving overall operational efficiency.

[0027] It should be noted that the method for seed treatment using this device includes the following steps: Step 1: Select the crop variety to be processed through the human-machine interface of the control box 6. The system will automatically call up the processing parameter package corresponding to the selected variety. The parameter package includes high-frequency pulse frequency, voltage amplitude, processing time, ozone concentration, light intensity of plant supplement light lamp 11 and running speed of conveyor belt 4. Step 2: Seeds fall from the discharge port of the external discharge machine into the conveyor belt 4. The electric push rod 14 drives the flat scraper 15 to spread the seeds into a single layer. The variable frequency speed control motor 3 starts and drives the conveyor belt 4 to run at a uniform speed, so that the seeds enter the high frequency electric field treatment area inside the closed cover 7. Step 3: The electric push rod 217 drives the cavity block 18 to close the hatch, and the air pump 20 starts to inflate the sealing airbag 19, so that the two ends of the sealing cover 7 are airtight.

[0028] Step 4: The high-frequency pulse emission device 12 is activated, forming a vertical high-frequency pulse electric field between the upper electrode 9 and the lower electrode 21, which acts on the seeds. At the same time, the ozone generator 13 releases low-concentration ozone, and the plant supplement light 11 provides full-spectrum illumination. The electric field, gas, and light environment are treated in a triple synergistic manner. Step 5: After processing, conveyor belt 4 transports the seeds to the outlet end, electric push rod 17 drives the hatch to open, and the seeds are automatically discharged; control box 6 records the variety, parameters, time and other data of this processing and uploads them to the local or cloud database to complete the batch processing process.

[0029] It should be added that the output frequency of the high-frequency pulse emission device 12 is preferably between 20kHz and 500kHz, and the voltage amplitude is controlled within the range of 10kV to 25kV. This parameter range has been experimentally verified to effectively induce reversible electroporation of seed cell membranes, which promotes the opening of water and ion channels without damaging the activity of the seed embryo. It is suitable for seed treatment of various crops such as wheat, corn, and rice. The ozone generator 13 releases an ozone concentration controlled between 0.05 and 0.1 ppm, which is lower than the national occupational health standard limit (0.1 mg / m³). 3It is harmless to the human body, and is sufficient to inhibit the growth of mold and pathogenic microorganisms, and can moderately activate the seed's endogenous antioxidant enzyme system to promote germination initiation; For medium-sized seeds such as wheat and soybeans, the conveyor belt speed is set to 0.1 m / min, corresponding to a processing time of 6 minutes; for small-sized vegetable seeds, the speed is adjusted to 0.05 m / min, and the processing time is extended to 12 minutes to ensure sufficient response to the electric field stimulation. The working principle of the above embodiments is as follows: During operation, at the start of work, the user selects the crop variety to be processed via the touchscreen on the control box 6. The equipment automatically calls up the corresponding processing parameters, including pulse frequency, voltage, processing time, ozone concentration, light intensity, and conveying speed, achieving one-button start. Seeds fall into the conveyor belt 4 from the external elevator or discharge port. Electric push rod 14 pushes the flat scraper 15 downward to spread the accumulated seeds into a single layer, avoiding stacking that affects the processing effect. Variable frequency speed control motor 3 drives electric roller 2 to rotate, driving the conveyor belt 4 to run smoothly. Support roller 5 supports the conveyor belt 4 to prevent sagging. Seeds enter the enclosed cover 7 (the enclosed cover 7 is made of insulating and flame-retardant material, preferably polycarbonate or fiberglass, with good electrical insulation performance and mechanical strength, ensuring safety during high-voltage operations) along with the conveyor belt 4. At this time, electric push rod 17 at both ends of the enclosed cover 7 is activated, pushing the cavity block 18 to close the hatch. Air pump 20 inflates the sealing airbag 19 fitted on the cavity block 18, and the inflated airbag fits tightly against the cabin body. The end face forms an effective seal to prevent ozone leakage. After sealing, the high-frequency pulse emission device 12 is powered on, and a high-intensity alternating electric field in the vertical direction is generated between the upper electrode plate 9 and the lower electrode plate 21. This field acts on the seeds on the conveyor belt 4, enhancing cell membrane permeability and promoting water absorption and physiological metabolism. At the same time, the ozone generator 13 releases low-concentration ozone evenly through the microporous diffuser tube to sterilize the seed surface and stimulate germination enzyme activity. The plant supplement light 11 emits full-spectrum light covering 400 to 780 nanometers, simulating the natural sunlight environment and activating the photochemical reaction inside the seed. The three physical factors work together to enhance seed vigor. After treatment, the conveyor belt 4 transports the seeds to the outlet end, the electric push rod 17 retracts, the hatch opens automatically, and the seeds are discharged smoothly, completing one treatment cycle. Throughout the process, the observation window 10 can be used to check the internal operating status at any time, and the wireless communication module uploads the operating data to a mobile phone or management terminal, supporting remote monitoring and fault warning, which facilitates efficient management and production traceability.

The high-frequency pulse treatment device for crop seeds according to claim 1, characterized in that: The variable frequency speed control motor (3) is controlled by a frequency converter, and the running speed of the conveyor belt (4) can be steplessly adjusted within the range of 0.05 to 0.5 m / min to adapt to the processing time requirements of different seeds.

9. The high-frequency pulse treatment device and method for crop seeds according to claim 1, characterized in that: The method for seed treatment using this device includes the following steps: Step 1: Select the crop variety to be processed through the human-machine interface of the control box (6). The system automatically calls the processing parameter package corresponding to the selected variety. The parameter package includes high frequency pulse frequency, voltage amplitude, processing time, ozone concentration, light intensity of plant supplement light lamp (11) and running speed of conveyor belt (4). Step 2: The seeds fall from the outlet of the external discharge machine into the conveyor belt (4). The electric push rod (14) drives the flat scraper (15) to spread the seeds into a single layer. The variable frequency speed control motor (3) starts and drives the conveyor belt (4) to run at a constant speed, so that the seeds enter the high frequency electric field treatment area inside the closed cover (7). Step 3: The electric push rod 2 (17) drives the cavity block (18) to close the hatch, and the air pump (20) starts to inflate the sealing airbag (19) to make the two ends of the sealing cover (7) airtight. Step 4: The high-frequency pulse emission device (12) is started, forming a high-frequency pulse electric field in a vertical direction between the upper electrode plate (9) and the lower electrode plate (21), which acts on the seeds. At the same time, the ozone generator (13) releases low-concentration ozone, and the plant supplement light (11) provides full-spectrum light. The electric field, gas and light environment are treated in a triple synergistic manner. Step 5: After processing, the conveyor belt (4) transports the seeds to the outlet end, and the electric push rod (17) drives the hatch to open, and the seeds are automatically discharged; the control box (6) records the variety, parameters, time and other data of this processing and uploads them to the local or cloud database to complete the batch processing process.
