Abstract
Description
Technical Field
[0001] This utility model belongs to the field of fruit storage technology, specifically relating to a digital simulated fruit for environmental monitoring throughout the entire process of commercial fruit processing. Background Technology
[0002] After harvesting, fruits require a series of processing techniques, such as sorting, grading, washing, drying, cutting, coating, packaging, labeling, and storage, to achieve a certain level of commercial quality and smoothly transition to the consumer market. This process is called the commercial processing of fruits. Commercial processing is a necessary stage in the transformation of fruit from agricultural products into commodities after harvest. However, the process and its environmental conditions are complex and often undetectable, making it highly susceptible to mechanical damage, physiological disorders, and bacterial infections. This results in a high post-harvest loss rate, leading to significant losses and resource waste.
[0003] Temperature, carbon dioxide concentration, and factors such as compression, collision, and vibration are the basic environmental conditions in the post-harvest commercialization process of fruit, and also the key factors leading to high post-harvest losses. If a digital simulation fruit can be developed to detect environmental scenario data throughout the entire post-harvest commercialization process, changes in environmental factors can be detected. This would enable the establishment of a traceability and early warning system and a post-harvest full-process control system, reducing safety hazards in the fruit commercialization process, improving detection, monitoring, and control technologies, and clarifying the key factors for post-harvest safety risk assessment of fruit, thereby achieving the goal of significantly reducing post-harvest loss rates.
[0004] Currently, artificial fruits are mainly used to replace real fruits in display situations where fruit arrangement is needed to achieve a visual effect, thus remaining primarily at the ornamental level. A utility model patent titled "A Multi-Shaped Artificial Fruit" further improves the functionality of artificial fruits. It includes a simulated fruit body with a control switch on one side of its bottom and a battery compartment on the other side containing a rechargeable battery. A groove is located at the bottom of the simulated fruit body, with a hydraulic cylinder at the top and a hydraulic rod at the bottom, with a roller at the bottom. The output of the rechargeable battery is electrically connected to the input of the control switch, and the output of the control switch is electrically connected to the hydraulic cylinder. A detachable assembly is located on one side of the upper part of the simulated fruit body, and a fixing rod is located near the detachable assembly in the middle of the simulated fruit body, allowing for changes in the shape of the simulated fruit. After the detachable assembly is removed, it can be used as a chair, offering multiple functions, easy mobility, and some storage capacity. However, it lacks the function of monitoring the entire post-harvest commercial processing process. Therefore, the development of a digital simulated fruit for environmental monitoring throughout the post-harvest commercial processing process is particularly urgent. Utility Model Content
[0005] To address the lack of digital simulation fruits for post-harvest environmental monitoring in existing technologies, this invention provides a digital simulation fruit for environmental monitoring throughout the entire commercial processing of fruit. It can record in real time the temperature, carbon dioxide concentration, and acceleration data caused by collisions, vibrations, and compression of fruit during commercial processing. This facilitates the establishment of a traceability and early warning system and a post-harvest control system, thereby clarifying the key factors for post-harvest safety risk assessment of fruit and achieving the goal of significantly reducing post-harvest loss rate.

[0018] Furthermore, the first simulated fruit body has a first connecting hole, a second connecting hole, a third connecting hole, and a fourth connecting hole with both ends communicating with the outside in the horizontal direction.

The second simulated fruit body also has a fifth connecting hole, a sixth connecting hole, a seventh connecting hole, and an eighth connecting hole with both ends communicating with the outside in the horizontal direction.

The simulated fruit body can be designed based on similar fruits to be tested, reducing the impact of the digital simulated fruit on other similar fruits. The simulated fruit body is composed of first and second simulated fruit bodies fixedly spliced together, facilitating grooved processing and thus convenient installation of an accelerometer, data processing system, and data transmission system.

[0027] This invention provides a digital simulation fruit for environmental monitoring throughout the entire process of commercial fruit processing. It targets common fruits with regular shapes and uniform flesh, using apples as an example. Figure 1 and Figure 2 Please provide an explanation. For example... Figure 2As shown, the digital simulated fruit mainly includes a first simulated fruit body 4, a second simulated fruit body 8, a temperature sensor 3, a carbon dioxide sensor 5, an acceleration sensor 9, a data processing system 11, a data transmission system 2, and a power supply system 10. The first simulated fruit body 4 and the second simulated fruit body 8 are spliced together and fixed to form a simulated fruit body corresponding to the fruit to be detected. The simulated fruit body is made of synthetic resin, and its basic physical properties and biomechanical characteristics (density, dimensions, elastic modulus, Poisson's ratio, and hardness) are comparable to those of the actual fruit it represents, thus enabling it to simulate real fruit. The simulated fruit has a groove inside, within which are arranged an accelerometer 9, a power supply system 10, a data processing system 11, and a data transmission system 2. The accelerometer 9 is fitted against the inner wall of the groove and can detect the mechanical factors affecting the fruit during the entire commercial processing process, including compression, vibration, and collision, to assess the degree of mechanical damage. The output of the accelerometer 9 is connected to the input of the data processing system 11, allowing the accelerometer data to be transmitted to the data processing system. The output of the data processing system 11 is connected to the input of the data transmission system 2, which can further transmit the accelerometer data to a receiving terminal, such as a host computer. A temperature sensor 3 and a carbon dioxide sensor 5 are embedded alternately in the simulated fruit. The detection ends of both the temperature sensor 3 and the carbon dioxide sensor 5 are in contact with the outside environment for easy acquisition of temperature and carbon dioxide data. The outputs of both the temperature sensor 3 and the carbon dioxide sensor 5 are connected to the input of the data processing system 11, allowing the temperature and carbon dioxide data to be transmitted to the data processing system. The data transmission system then transmits this data to the aforementioned receiving terminal. By utilizing temperature, acceleration, and carbon dioxide data, a traceability and early warning system and a post-harvest full-process control system can be established to reduce safety hazards in the commercial processing of fruits, improve detection, monitoring, and control technologies, and identify key factors for post-harvest safety risk assessment of fruits, thereby achieving the goal of significantly reducing post-harvest loss rates.
[0028] Figure 1 In this system, the output terminal of the power supply system 10 is connected to the power input terminal of the data transmission system 2, the power input terminal of the temperature sensor 3, the power input terminal of the carbon dioxide sensor 5, the power input terminal of the acceleration sensor 9, and the power input terminal of the data processing system 11, respectively. In this way, the power supply system 10 can provide the power to the temperature sensor 3, the carbon dioxide sensor 5, the acceleration sensor 9, the data processing system 11, and the data transmission system 2.
[0029] This invention features a power supply system 10 attached to one side wall of an accelerometer sensor 9, with the upper surface of the power supply system 10 higher than the upper surface of the accelerometer sensor 9. A data processing system 11 is arranged on the upper surface of the accelerometer sensor 9, with one end of the upper surface of the data processing system 11 flush with the upper surface of the power supply system 10. A data transmission system 2 is attached to the other side wall of the accelerometer sensor 9, with the upper surface of the data transmission system 2 flush with the upper surface of the accelerometer sensor 9 and the lower surface of the data transmission system 2 flush with the lower surface of the power supply system 10. The lower surface of the accelerometer sensor 9 is lower than both the data transmission system 2 and the accelerometer sensor 9. The power supply system 10, data processing system 11, and data transmission system 2, along with the accelerometer sensor 9, form a single unit. All sensors 9 are cuboid in shape. For ease of installation, certain requirements apply to their length, width, and height. After the wiring is completed, the power supply system 10, data processing system 11, and data transmission system 2 can be assembled into a cube. This cube is not a solid cube; the accelerometer 9 is located at the center of this cube. Below the accelerometer 9 is a hollow cuboid region with the same length and width as the accelerometer 9, and the same height as the data processing system 11. This facilitates installation by creating slots in the first simulated fruit body 4 and the second simulated fruit body 8, and also makes it easy to position the accelerometer 9 at the center of the simulated fruit body. For ease of description, the entire assembly consisting of the power supply system 10, data processing system 11, data transmission system 2, and accelerometer 9 is referred to as the assembled body.
[0030] Based on the above design concept, the first simulated fruit body 4 and the second simulated fruit body 8 are designed to have the same shape. The contact surface formed after their splicing is distributed vertically, thus providing both the first and second simulated fruit bodies 4 and 8 with a flat surface and relatively regular shape, making them easy to obtain. A first groove is then formed on the opposing surfaces of the first and second simulated fruit bodies 4, and a second groove is formed on the opposing surface of the second simulated fruit body 8. The two grooves have the same cross-sectional shape and size. When the first and second grooves are aligned, they form the aforementioned groove, in which the spliced body can be placed and fit snugly against its inner wall. The center of the accelerometer 9 coincides with the center of the simulated fruit body.
[0031] Temperature sensor 3 and carbon dioxide sensor 5 are specifically positioned on the cross-section at the center of the simulated fruit body. The line connecting their centers passes through the center of the simulated fruit body, allowing for the collection of temperature and carbon dioxide data relative to the center of the corresponding fruit. During installation, a first horizontally distributed notch is made on the first simulated fruit body 4 at the position corresponding to temperature sensor 3, and a second horizontally distributed notch is made on the second simulated fruit body 8 at the position corresponding to carbon dioxide sensor 5. Temperature sensor 3 can be embedded in the first notch, and carbon dioxide sensor 5 can be embedded in the second notch. To facilitate the connection of temperature sensor 3 and carbon dioxide sensor 5 to data processing system 11, a guide groove extends inward from one end of each of the first and second notches. The ends of these two guide grooves are connected to the two end faces of data processing system 11, respectively, allowing for wiring and connection to data processing system 11.
[0032] To tightly connect the first simulated fruit body 4 and the second simulated fruit body 8, through holes need to be made in both, and they need to be connected by 4 pairs of bolts and nuts. The specific operation method is as follows:
[0033] In the first simulated fruit body 4, four connecting holes 1, 12, 13, and 14, all connected to the outside at both ends, are formed along the horizontal direction. These holes are all stepped. The end of each connecting hole 1, 12, 13, and 14 furthest from the second simulated fruit body 8 is the wider end, with a regular hexagonal cross-section, while the other end is the narrower end, cylindrical in shape. Similarly, in the second simulated fruit body 8, four connecting holes 5, 6, 7, and 8, all cylindrical in shape and connected to the outside at both ends, are formed along the horizontal direction. These are all stepped holes, with the narrower end closest to the first simulated fruit body 4. The narrow end inner diameter of the fifth connecting hole is the same as the narrow end inner diameter of the first connecting hole 1 and their central axes coincide. The narrow end inner diameter of the sixth connecting hole is the same as the narrow end inner diameter of the second connecting hole 12 and their central axes coincide. The narrow end inner diameter of the seventh connecting hole is the same as the narrow end inner diameter of the third connecting hole 13 and their central axes coincide. The narrow end inner diameter of the eighth connecting hole is the same as the narrow end inner diameter of the fourth connecting hole 14 and their central axes coincide. The first connecting hole 1 and the second connecting hole 12 are centrally symmetrical about the length direction of the cube. The third connecting hole 13 and the fourth connecting hole 14 are centrally symmetrical about the length direction of the cube. The third connecting hole 13 is specifically located directly below the first connecting hole 1.
[0034] A first bolt 6 is passed through the first connecting hole 1, with its shank passing through the wide end of the first connecting hole 1. The end of the shank of the first bolt 6 is located in the wide end of the fifth connecting hole. A first nut is installed at the end of the shank of the first bolt 6, and the first nut is fitted against the inner wall of the wide end of the fifth connecting hole. The inner wall of the first nut is located at the step of the fifth connecting hole. A second bolt 15 is passed through the second connecting hole 12, with its shank passing through the wide end of the second connecting hole 12. The end of the shank of the second bolt 15 is located in the wide end of the sixth connecting hole. A second nut is installed at the end of the shank of the second bolt 15, and the second nut is fitted against the inner wall of the wide end of the sixth connecting hole. The inner wall of the second nut is located at the step of the sixth connecting hole. A third bolt 16 is passed through the third connecting hole 13, with its shank passing through the wide end of the third connecting hole 13. The end of the shank of the third bolt 16 is located in the wide end of the seventh connecting hole. A third nut is installed at the end of the shank of the third bolt 16, and the third nut is fitted against the inner wall of the wide end of the seventh connecting hole. The inner wall of the third nut is located at the step of the seventh connecting hole. The fourth bolt 17 passes through the fourth connecting hole 14, with its shank passing through the wide end of the fourth connecting hole 14. The end of the shank of the fourth bolt 17 is located in the wide end of the eighth connecting hole. A fourth nut is installed at the end of the shank of the fourth bolt 17, and the fourth nut fits against the inner wall of the wide end of the eighth connecting hole. The inner wall of the fourth nut is located at the step of the eighth connecting hole. As an explanation, Figure 2 The second nut was selected, and the second nut port 7 is installed at the end of the shank of the second bolt 15.
[0035] In this invention, the data processing system 11 is specifically an STM32 microcontroller that collects data, and the data transmission system 2 is specifically a Bluetooth data transmission system. The receiving end needs to be equipped with a Bluetooth receiver, which can receive acceleration, temperature and carbon dioxide data sent by the Bluetooth data transmission system.
[0036] In practical use, the digital simulated fruit of this invention is placed evenly and spaced among real fruit. It can detect changes in environmental factors during the storage of the fruit in commercial processing. Temperature sensor 3, carbon dioxide sensor 5, and acceleration sensor 9 record temperature, carbon dioxide concentration, and acceleration data caused by collision, vibration, and compression in real time, respectively. The data is transmitted to data transmission system 2 through data processing system 11 and then received by the terminal. This facilitates the establishment of a traceability and early warning system and a post-harvest full-process control system. This helps to identify key factors for post-harvest safety risk assessment of fruit, thereby achieving the goal of significantly reducing post-harvest loss rate.
[0037] A traceability and early warning system can record and monitor the entire process of fruit production and sales in real time, ensuring that data at every stage is traceable, thereby promptly identifying and addressing potential safety hazards. A post-harvest full-process control system further guarantees fruit quality and safety by strictly controlling the processing, storage, and transportation of fruit. Both traceability and early warning systems and post-harvest full-process control systems are highly necessary and have broad application prospects in multiple areas related to fruit commercialization.
