[0002] As consumers' requirements for food quality continue to increase, especially in the field of cold chain logistics, how to ensure that food maintains its original shape and freshness during the distribution process has become an important challenge facing companies. As a hot-selling product in the frozen food area of ​​supermarkets, the appearance and quality of quick-frozen raw products directly affect consumers' purchasing decisions. However, quick-frozen raw products often deform or crack on the surface due to temperature fluctuations or bumps during transportation.

[0007] Furthermore, the second adjustment module includes: A fluctuation calculation unit, used to calculate the standard deviation of the real-time deformation displacement to form a deformation fluctuation value; a fluctuation comparison unit connected to the fluctuation calculation unit and used to compare the deformation fluctuation value with a preset standard displacement fluctuation value to form a deformation comparison result; A second adjustment unit is connected to the fluctuation comparison unit, and is used to adjust the first expansion amount according to the deformation comparison result, the deformation fluctuation value and the preset standard displacement fluctuation value to form the second expansion amount.

[0008] Furthermore, the fluctuation calculation unit is also used to calculate the standard deviation of the real-time crack width to form a crack fluctuation value.

[0009] Furthermore, the fluctuation comparison unit is also used to compare the crack fluctuation value with a preset standard crack fluctuation value to form a crack comparison result.

[0010] Furthermore, the second adjustment unit is further used to adjust the first temperature according to the crack comparison result, the crack fluctuation value and the preset standard crack fluctuation value to form the second temperature.

[0011] Furthermore, the correction module includes: A correction calculation unit, used to calculate the standard deviation of the second expansion amount to form a second expansion fluctuation value; A correction unit is connected to the correction calculation unit and is used to correct the preset extraction area according to the second expansion and contraction fluctuation value and a preset standard expansion and contraction fluctuation value.

[0012] Furthermore, the correction calculation unit is also used to calculate the standard deviation of the second temperature to form a second temperature fluctuation value.

[0013] Furthermore, the correction unit is further used to correct the preset standard pressure according to the second temperature fluctuation value and the preset standard temperature fluctuation value.

[0014] Furthermore, the first adjustment module includes: A pressure comparison unit, used to compare the real-time pressure with the preset standard pressure to form a pressure comparison result; The first adjustment unit is connected to the pressure comparison unit and is used to adjust the preset expansion amount according to the pressure comparison result to form a first expansion amount, or to adjust the preset temperature according to the pressure comparison result to form a first temperature.

[0015] Furthermore, the first adjustment unit includes: A telescopic adjustment subunit, used for adjusting the preset telescopic amount according to the pressure comparison result and a preset first adjustment coefficient to form a first telescopic amount; The temperature adjustment subunit is used to adjust the preset temperature according to the quantity of the pressure comparison results and the preset quantity to form a first temperature.

[0016] Compared with the prior art, the beneficial effect of the present invention is that by real-time monitoring of the pressure of the telescopic table and the deformation and crack width of the surface of the quick-frozen buns during transportation, the system can quickly and accurately detect the pressure damage that may be caused to the food during transportation. The function of intelligently adjusting the telescopic amount and temperature ensures that the quick-frozen buns always maintain the best state during transportation, reducing cracks and deformation caused by excessive pressure or improper temperature. The dynamic correction capability of the system can be optimized based on long-term data feedback to avoid food damage caused by vehicle speed or environmental changes, ensure the quality and freshness of the quick-frozen buns, reduce losses during food transportation, and effectively solve the problem of poor food status during transportation due to low regulation of dynamic factors during transportation.

[0017] By real-time monitoring and adjusting the expansion and contraction amount, the first adjustment module can accurately control the pressure of the quick-frozen buns during transportation, avoiding deformation or cracking of the quick-frozen buns due to excessive pressure, or shaking and damage of the quick-frozen buns during transportation due to insufficient pressure, thereby ensuring the stability of the quality of the quick-frozen buns during transportation.

[0018] Through the coordinated work of the telescopic adjustment subunit and the temperature adjustment subunit, precise control based on pressure changes is achieved. Not only can the telescopic amount of the telescopic table be quickly adjusted when there is a real-time pressure deviation to ensure that the quick-frozen buns are stably fixed, but the temperature can also be automatically adjusted when the pressure changes frequently to ensure the quality and shape stability of the quick-frozen buns during transportation.

[0019] Through dynamic monitoring and adjustment, we can ensure that the deformation of quick-frozen buns can be dealt with in real time during transportation. Using standard deviation to quantify deformation fluctuations can effectively identify deformations that exceed the normal range, so as to adjust the expansion and contraction amount in time.

[0020] By calculating the standard deviation of the real-time crack width and forming the crack fluctuation value, the system can timely identify the fluctuation of cracks on the surface of the quick-frozen buns, and then evaluate their integrity and quality.

[0021] By comparing the crack fluctuation value with the preset standard crack fluctuation value, the system can monitor the crack condition of quick-frozen buns during transportation in real time. If the crack fluctuation value exceeds the preset standard, the system can take timely adjustment measures, such as reducing the transportation speed or increasing temperature control, to prevent further crack expansion.

[0022] By adjusting the first temperature according to the crack comparison results and fluctuation values, the system can achieve precise control of the temperature of the quick-frozen buns and prevent the expansion of cracks caused by improper temperature.

[0023] By introducing the correction module and its calculation and adjustment mechanism, the system can dynamically adapt to changes that occur during the transportation process, thereby monitoring and optimizing the storage conditions of the quick-frozen buns in real time.

[0024] By calculating and analyzing the second temperature fluctuation value, the system can promptly detect and correct temperature control abnormalities to ensure the quality and safety of quick-frozen buns during transportation.

[0025] Through the dynamic adjustment mechanism, the system can respond to temperature changes in a timely manner to ensure that appropriate pressure is always maintained during transportation. This not only reduces the risk of food damage caused by temperature and pressure mismatch, but also improves overall delivery efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] See also Figure 1 As shown, it is a schematic diagram of the food distribution system of this embodiment; Please continue reading Figure 2 As shown, it is a schematic top view of the transport box of this embodiment; The frozen food section of supermarkets is an important consumer choice. As a popular fast food, frozen buns have high requirements for appearance, taste and quality. Frozen buns must not only remain intact when displayed in the supermarket, but also restore the best taste when steamed at home.

[0032] Therefore, this embodiment provides a food delivery system, comprising: A data acquisition module, used to collect the real-time pressure of each telescopic table 1 in each square storage compartment 2 in the transport box 3 during transportation, and the real-time image of the quick-frozen buns fixed by a plurality of telescopic tables 1 with a preset telescopic amount; The transport box 3 is operated at a preset temperature, a single quick-frozen bun is placed in each storage compartment 2, and four telescopic tables 1 are arranged in the horizontal direction in each storage compartment 2; An extraction module, connected to the data acquisition module, for extracting the real-time deformation displacement at the contact position between each telescopic platform 1 and the quick-frozen bun according to the real-time image and a preset extraction area, and extracting the real-time crack width on the surface of the quick-frozen bun according to the real-time image; A first adjustment module, connected to the data acquisition module, for adjusting the preset expansion amount according to the real-time pressure and the preset standard pressure to form a first expansion amount, or adjusting the preset temperature to form a first temperature; A second adjustment module, which is connected to the first adjustment module and the extraction module respectively, and is used to adjust the first expansion amount according to all the real-time deformation displacements within a preset evaluation time length to form a second expansion amount, or adjust the first temperature according to all the real-time crack widths and a preset standard width fluctuation value within a preset evaluation time length to form a second temperature; A correction module, which is connected to the data acquisition module and the second adjustment module respectively, is used to correct the preset extraction area according to all the second expansion amounts within a preset correction time length, or to correct the preset standard pressure according to all the second temperatures within a preset correction time length.

[0033] The preset telescopic amount is the default telescopic distance of the telescopic platform in the initial state, which is used to ensure that the quick-frozen buns are fixed in the storage compartment 2 at a suitable pressure state. It depends on the size, shape, material, space in the transport box 3 and the stability of the transportation environment of the quick-frozen buns. It is usually set between 0.5 cm and 2 cm, and the specific value is determined by the volume of the quick-frozen buns and the structure of the transport box 3. In this embodiment, the preset telescopic amount is set to 1.5 cm. It can ensure that the quick-frozen buns are not over-compressed and deformed during transportation, and can also prevent the quick-frozen buns from loosening during transportation and causing collision damage.

[0034] The preset temperature is the initial temperature in the transport box 3, which is used to keep the food fresh and prevent it from spoiling during transportation. It depends on the type of food, the transportation time, the external temperature of the transportation environment and the optimal storage temperature range of the food. It is usually set between 0°C and 5°C, which is suitable for preserving perishable foods such as quick-frozen buns. In this embodiment, the preset temperature is set to 4°C. It can effectively extend the shelf life of quick-frozen buns, prevent quick-frozen buns from spoiling due to excessively high temperatures, and prevent quick-frozen buns from freezing hard due to excessively low temperatures.

[0035] The preset extraction area is the area defined by the system when extracting the contact point between the quick-frozen buns and the telescopic table, which is used to analyze the deformation displacement of the quick-frozen buns. It depends on the surface area of ​​the quick-frozen buns, the contact area of ​​the telescopic table, and the shape of the quick-frozen buns. It is usually set between 5%-15% of the surface area of ​​the quick-frozen buns, and the specific range is determined by the size of the quick-frozen buns. In this embodiment, the preset extraction area is set to 10% of the surface area of ​​the quick-frozen buns, which can ensure sufficient contact area for monitoring while avoiding inaccurate data caused by covering too large an area.

[0036] The preset standard pressure is the pressure initially set by the system, which is used to ensure that the pressure on the quick-frozen buns during transportation does not exceed its tolerance range. It depends on the softness of the food, its pressure bearing capacity and the frequency of transportation vibration. It is usually set between 10Pa-50Pa, and the specific value depends on the pressure bearing capacity of the food. In this embodiment, the preset standard pressure is set to 30Pa, which can ensure that the quick-frozen buns will not crack or deform due to excessive squeezing during transportation. The moderate pressure can ensure that the quick-frozen buns are stably fixed in the storage compartment 2.

[0037] The preset evaluation time is the time that the system continuously monitors the telescopic table and the status of the quick-frozen buns within a certain period of time, which is used to evaluate the changing trend of pressure and deformation. It depends on the transportation time, the frequency of real-time environmental changes, and the speed of change of food status. It is usually set at 10 minutes to 30 minutes, and the specific duration depends on the transportation conditions. In this embodiment, the preset evaluation time is set to 20 minutes, which can balance the frequency of real-time monitoring and the accuracy of data analysis, and can promptly detect abnormal conditions in transportation while avoiding too frequent adjustments.

[0038] The preset correction time is the time interval for the system to perform correction operations based on long-term data analysis, which depends on the speed of change of food status, the stability of transportation conditions, and the frequency of data fluctuations. It is usually set between 0.8 hours and 2 hours. In this embodiment, the preset correction time is set to 1 hour. The system parameters can be adjusted according to the long-term trend to ensure that the quick-frozen buns are always in the best state during transportation. When the environment gradually becomes cold during long-distance transportation, the 1-hour correction can adjust the temperature and expansion amount in time to prevent the quick-frozen buns from cracking or deteriorating due to temperature fluctuations.

[0039] The data acquisition module monitors in real time the pressure of the telescopic table 1 on the quick-frozen buns in each square storage compartment 2 in the transport box 3 and the real-time image of the quick-frozen buns. The extraction module extracts the contact point displacement between the telescopic table 1 and the quick-frozen buns and the crack width on the surface based on the image data. The system adjusts the telescopic amount of the telescopic table 1 and the temperature of the transport box 3 according to the pressure or temperature through the first adjustment module. Then, the second adjustment module further optimizes the telescopic amount or temperature based on the deformation displacement and crack width within the evaluation period. Finally, the correction module corrects the preset extraction area and standard pressure according to the telescopic amount and temperature in the long term to ensure the stability of the system and the quality of the food.

[0040] By real-time monitoring of the pressure of the telescopic platform 1 and the deformation and crack width of the surface of the quick-frozen buns during transportation, the system can quickly and accurately detect possible pressure damage to food during transportation. The function of intelligently adjusting the telescopic amount and temperature ensures that the quick-frozen buns always maintain the best condition during transportation, reducing cracks and deformation caused by excessive pressure or improper temperature. The system's dynamic correction capability can be optimized based on long-term data feedback to avoid food damage caused by vehicle speed or environmental changes, ensure the quality and freshness of the quick-frozen buns, reduce food losses during transportation, and effectively solve the problem of poor food status during transportation due to low regulation of dynamic factors during transportation.

[0041] Please continue reading Figure 3 As shown, it is a decision logic diagram of the first adjustment module adjusting the preset expansion amount in this embodiment; Specifically, the first adjustment module includes: A pressure comparison unit, used to compare the real-time pressure with the preset standard pressure to form a pressure comparison result; A first adjustment unit is connected to the pressure comparison unit, and is used to increase the preset expansion amount to form a first expansion amount when the pressure comparison result shows that the real-time pressure is less than the preset standard pressure, or to adjust the preset temperature to form a first temperature when the pressure comparison result shows that the real-time pressure is greater than or equal to the preset standard pressure.

[0042] The pressure comparison unit compares the real-time pressure with the preset standard pressure to generate a pressure comparison result. Then, the first adjustment unit adjusts the preset expansion amount of the expansion platform according to the pressure comparison result to generate a first expansion amount, so as to ensure that the pressure of the quick-frozen buns during transportation is kept within an appropriate range.

[0043] By real-time monitoring and adjusting the expansion and contraction amount, the first adjustment module can accurately control the pressure of the quick-frozen buns during transportation, avoiding deformation or cracking of the quick-frozen buns due to excessive pressure, or shaking and damage of the quick-frozen buns during transportation due to insufficient pressure, thereby ensuring the stability of the quality of the quick-frozen buns during transportation.

[0044] Specifically, the first adjustment unit includes: a telescopic adjustment subunit, configured to increase the preset telescopic amount according to the pressure comparison result and a preset first adjustment coefficient to form a first telescopic amount when the pressure comparison result shows that the real-time pressure is less than the preset standard pressure; The temperature adjustment subunit is used to adjust the preset temperature according to the number of pressure comparison results and the preset number to form a first temperature when the pressure comparison result shows that the real-time pressure is greater than or equal to the preset standard pressure. When the number is greater than the preset number, it indicates that the quick-frozen buns are squeezed against multiple telescopic tables 1. The temperature adjustment subunit determines that the quick-frozen buns have expanded and the preset temperature is set too high.

[0045] The preset first adjustment coefficient is a proportional coefficient used to determine how much the expansion and contraction amount should be adjusted in the pressure comparison result. It depends on the physical properties of the quick-frozen buns, the stability of the transportation environment, and the mechanical properties of the expansion and contraction platform 1 in the storage compartment 2. It is usually set between 0.1 and 1.0, and is set to 0.5 in this embodiment to balance the sensitivity and stability of the adjustment, ensuring that the quick-frozen buns can be adjusted appropriately when the pressure changes without excessive adjustment.

[0046] The preset number refers to a standard value used in the system to judge the pressure state of the telescopic table 1, specifically the number of telescopic tables 1 whose pressure exceeds the preset standard pressure. When the pressure of telescopic tables 1 exceeding the preset number in a certain storage compartment 2 is too high, the system will think that the quick-frozen buns have significantly squeezed multiple telescopic tables 1, which indicates that the quick-frozen buns have expanded due to excessive temperature. It is usually set between 2 and 4, and is set to 3 in this embodiment, which can prevent the quick-frozen buns from further expanding.

[0047] First, based on the comparison result between the real-time pressure and the preset standard pressure, combined with the preset first adjustment coefficient, the preset expansion amount of the expansion platform is dynamically adjusted to form a first expansion amount to ensure that the quick-frozen buns are subjected to appropriate fixed pressure during transportation to avoid excessive squeezing or loosening. The temperature adjustment subunit analyzes the number and frequency of pressure comparison results, combined with the preset standard adjustment quantity, and dynamically adjusts the preset temperature to form a first temperature to meet the freezing or preservation needs of the quick-frozen buns under different pressure changes.

[0048] Through the coordinated work of the telescopic adjustment subunit and the temperature adjustment subunit, precise control based on pressure changes is achieved. Not only can the telescopic amount of the telescopic platform 1 be quickly adjusted when there is a real-time pressure deviation to ensure that the quick-frozen buns are stably fixed, but the temperature can also be automatically adjusted when the pressure changes frequently to ensure the quality and shape stability of the quick-frozen buns during transportation.

[0049] Please continue reading Figure 4As shown, it is a decision logic diagram of the second adjustment unit adjusting the first expansion amount in this embodiment; Specifically, the second adjustment module includes: A fluctuation calculation unit, used to calculate the standard deviation of the real-time deformation displacement to form a deformation fluctuation value; a fluctuation comparison unit connected to the fluctuation calculation unit and used to compare the deformation fluctuation value with a preset standard displacement fluctuation value to form a deformation comparison result; A second adjustment unit is connected to the fluctuation comparison unit, and is used to adjust the first expansion amount according to the deformation fluctuation value and the preset standard displacement fluctuation value to form the second expansion amount when the deformation comparison result shows that the deformation fluctuation value is greater than the preset standard displacement fluctuation value.

[0050] The adjusted first expansion amount is equal to the preset expansion amount plus an adjustment amount, which is obtained by multiplying the difference between the deformation fluctuation value and the preset standard displacement fluctuation value by an adjustment coefficient. If the deformation fluctuation value is greater than the preset standard displacement fluctuation value, the system increases the first expansion amount to cope with the excessive pressure on the quick-frozen buns; if the deformation fluctuation value is less than or equal to the preset standard displacement fluctuation value, the system will reduce the first expansion amount to protect the shape of the quick-frozen buns.

[0051] The preset standard displacement fluctuation value is a reference value set in the system, which is used to measure the acceptable deformation fluctuation range of quick-frozen buns during transportation. It represents the maximum fluctuation range allowed for deformation of quick-frozen buns under normal conditions due to factors such as temperature changes and external forces. It depends on the physical properties of the quick-frozen buns, the temperature and humidity of the storage and transportation environment, and the shocks and vibrations that may be suffered during transportation. It is usually set between 1 mm and 5 mm, and this embodiment is set to 2 mm, which can effectively balance the quality and transportation safety of the quick-frozen buns.

[0052] The standard deviation of the real-time deformation displacement is first calculated by the fluctuation calculation unit to obtain the deformation fluctuation value. Then, the fluctuation comparison unit compares the deformation fluctuation value with the preset standard displacement fluctuation value to generate a deformation comparison result. If the deformation fluctuation value is greater than the preset standard displacement fluctuation value, the second adjustment unit will adjust the first expansion amount according to the comparison result to generate the second expansion amount to ensure the stability of the shape of the quick-frozen buns.

[0053] Through dynamic monitoring and adjustment, we can ensure that the deformation of quick-frozen buns can be dealt with in real time during transportation. Using standard deviation to quantify deformation fluctuations can effectively identify deformations that exceed the normal range, so as to adjust the expansion and contraction amount in time.

[0054] Specifically, the fluctuation calculation unit is also used to calculate the standard deviation of the real-time crack width to form a crack fluctuation value.

[0055] By monitoring the crack width of quick-frozen buns in real time, collecting crack width data within a certain period of time, and calculating the standard deviation of these data, the crack fluctuation value is formed. This fluctuation value reflects the change in crack width during the monitoring period, thus helping the system understand the degree of impact on quick-frozen buns during transportation.

[0056] By calculating the standard deviation of the real-time crack width and forming the crack fluctuation value, the system can timely identify the fluctuation of cracks on the surface of the quick-frozen buns, and then evaluate their integrity and quality.

[0057] Specifically, the fluctuation comparison unit is further used to compare the crack fluctuation value with a preset standard crack fluctuation value to form a crack comparison result.

[0058] The preset standard crack fluctuation value refers to the allowable fluctuation range of the crack width on the surface of the quick-frozen buns during transportation. It is a benchmark value obtained through experiments and historical data analysis, which aims to ensure that under normal transportation conditions, changes in the cracks of the quick-frozen buns will not affect their quality and taste. It depends on the type of quick-frozen buns, material properties, transportation conditions, and market requirements for food appearance and quality. It is usually set between 0.1 mm and 0.5 mm, and in this embodiment it is set to 0.2 mm to ensure that the system can promptly identify the potential risk of crack expansion, and then adjust the transportation conditions or temperature control strategy.

[0059] The fluctuation comparison unit receives the crack fluctuation value from the fluctuation calculation unit and compares it with the preset standard crack fluctuation value. Through this comparison, the system can determine whether the real-time crack fluctuation is within the expected range and generate a crack comparison result, reflecting the degree of change of the crack situation on the surface of the quick-frozen buns.

[0060] By comparing the crack fluctuation value with the preset standard crack fluctuation value, the system can monitor the crack condition of quick-frozen buns during transportation in real time. If the crack fluctuation value exceeds the preset standard, the system can take timely adjustment measures, such as reducing the transportation speed or increasing temperature control, to prevent further crack expansion.

[0061] Specifically, the second adjustment unit is further used to adjust the first temperature according to the crack comparison result, the crack fluctuation value and the preset standard crack fluctuation value to form the second temperature.

[0062] The crack comparison results, crack fluctuation values ​​and preset standard crack fluctuation values ​​are analyzed. When the crack fluctuation value is detected to exceed the preset standard, the system will determine that the cracks of the quick-frozen buns may be enlarged due to improper temperature setting. Based on these data, the second adjustment unit can calculate the required temperature adjustment and form a new second temperature to optimize the environmental conditions in the packaging box.

[0063] By adjusting the first temperature according to the crack comparison results and fluctuation values, the system can achieve precise control of the temperature of the quick-frozen buns and prevent the expansion of cracks caused by improper temperature.

[0064] Specifically, the correction module includes: A correction calculation unit, used to calculate the standard deviation of the second expansion amount to form a second expansion fluctuation value; A correction unit is connected to the correction calculation unit and is used to correct the preset extraction area according to the second expansion and contraction fluctuation value and a preset standard expansion and contraction fluctuation value.

[0065] The correction module first calculates the standard deviation of the second expansion amount using the correction calculation unit to generate a second expansion fluctuation value. Subsequently, the correction unit compares the second expansion fluctuation value with the preset standard expansion fluctuation value to determine whether the current expansion amount change is within an acceptable range. If the second expansion fluctuation value exceeds the preset standard, the correction unit will adjust the preset extraction area accordingly to ensure the stability and safety of the quick-frozen buns during transportation.

[0066] The preset standard expansion and contraction fluctuation value refers to the allowable range of expansion and contraction variation of each expansion and contraction platform 1 during transportation, which is used to ensure that the quick-frozen buns are properly fixed and protected during transportation, and usually depends on the type of quick-frozen buns, packaging material characteristics, transportation conditions and user expectations of food quality. It is generally set between 0.5 and 1.5 mm, and is set to 1 mm in this embodiment to ensure that the quick-frozen buns can be properly supported.

[0067] By introducing the correction module and its calculation and adjustment mechanism, the system can dynamically adapt to changes that occur during the transportation process, thereby monitoring and optimizing the storage conditions of the quick-frozen buns in real time.

[0068] Specifically, the correction calculation unit is further used to calculate the standard deviation of the second temperature to form a second temperature fluctuation value.

[0069] The correction calculation unit calculates the standard deviation of the second temperature to form a second temperature fluctuation value, which is intended to monitor the temperature changes during transportation. By collecting temperature data in real time, the system can analyze the volatility of these data and evaluate the stability of the temperature control system. When the temperature fluctuation exceeds the preset range, the system will trigger corresponding adjustment measures to ensure that the temperature remains within the ideal range, thereby effectively controlling the storage conditions of the quick-frozen buns.

[0070] By calculating and analyzing the second temperature fluctuation value, the system can promptly detect and correct temperature control abnormalities to ensure the quality and safety of quick-frozen buns during transportation.

[0071] Specifically, the correction unit is further used to correct the preset standard pressure according to the second temperature fluctuation value and the preset standard temperature fluctuation value.

[0072] The corrected standard pressure is equal to the original preset standard pressure multiplied by a correction factor. This correction factor is 1 plus a preset correction coefficient, which represents the degree of influence of temperature fluctuation on pressure, multiplied by the ratio of the difference between the second temperature fluctuation value and the preset standard temperature fluctuation value to the preset standard temperature fluctuation value. In this way, the corrected standard pressure can be dynamically adjusted according to temperature fluctuations to ensure the stability and effectiveness of the system under different temperature conditions.

[0073] The preset correction coefficient is used to measure the degree of influence of temperature fluctuation on the preset standard pressure. In this system, when the temperature fluctuation exceeds a certain range, the preset standard pressure is adjusted by the preset correction coefficient to maintain the balance of pressure and temperature. It depends on the relationship between temperature and pressure, the characteristics of the transported food, and environmental factors. It is usually set between 0.1 and 1. In this embodiment, it is set to 0.5, which can adjust the pressure in time when the temperature fluctuates to avoid excessive pressure differences affecting the quality of the food.

[0074] The correction unit adjusts the preset standard pressure by comparing the second temperature fluctuation value with the preset standard temperature fluctuation value. When the actual temperature fluctuation exceeds the preset standard, the system identifies potential temperature control problems and adjusts the standard pressure accordingly to ensure the effective operation of the temperature control equipment. This process ensures the coordination of pressure and temperature, enabling the system to maintain a stable working state under different environmental conditions, thereby effectively protecting the quality of quick-frozen buns during transportation.

[0075] Through the dynamic adjustment mechanism, the system can respond to temperature changes in a timely manner to ensure that appropriate pressure is always maintained during transportation. This not only reduces the risk of food damage caused by temperature and pressure mismatch, but also improves overall delivery efficiency.
