[0003] Chinese Patent Publication No.: CN116911878A discloses a meat supply chain traceability system and method, the system includes multiple blockchain nodes, multiple radio frequency tags, multiple radio frequency readers, data acquisition terminals and traceability information display terminals; the blockchain nodes are used for data storage and broadcasting, as well as verification of data uploaders, and the number of blockchain nodes is not less than the number of supply chain participants; the radio frequency tags are used to record the traceability information of meat products; the radio frequency reader is connected to the blockchain node, used to read and write data and upload data to the blockchain node; the data acquisition terminal is connected to the blockchain node, used to collect process processing data of meat products; the traceability information display terminal is connected to the blockchain node, used to obtain and display the traceability information of meat products. It can be seen that the meat supply chain traceability system and method have the problem that the state of meat products is abnormal due to the change in the length of time that meat products are in a non-insulated state, thereby causing the stability of meat transportation to decrease. Summary of the invention

[0004] To this end, the present invention provides a meat supply chain management system based on blockchain, so as to overcome the problem in the prior art that the stability of meat transportation is reduced due to the abnormal state of meat products caused by the change in the time that meat products are in a non-insulated state.

[0005] To achieve the above-mentioned purpose, the present invention provides a meat supply chain management system based on blockchain, comprising: a supply chain management module, which is used to control the operation status of the meat supply chain through blockchain, including a cold storage management unit for controlling the cold storage status, a transportation status control unit connected to the supply chain for controlling the operation status of the transportation node, and an order processing unit connected to the transportation status control unit for processing meat orders; a data acquisition module, which is connected to the supply chain management module and is used to collect primary meat characteristic data; a data processing module, which is connected to the data acquisition module and is used to analyze and calculate the primary meat characteristic data to output secondary meat characteristic data; a storage module, which is respectively connected to the data acquisition module and the data processing module, and is used to store the primary meat characteristic data and the secondary meat characteristic data respectively. Secondary meat characteristic data; a control module, which is respectively connected to the supply chain management module, the data acquisition module, the data processing module and the storage module, to determine the first working mode of the conveying state control unit according to the proportion of the number of returned orders in a number of meat orders and the linear fit between the time taken to transport the meat products and the average temperature during the transportation of the meat products, and to determine the proportion of the storage capacity of the meat conveying data according to the linear fit between the time taken to transport the meat products and the average temperature during the transportation of the meat products and the update delay time of the meat conveying data, and to determine the second working mode of the conveying state control unit according to the temperature rise rate of the transportation process; wherein, the single standard conveying quantity of meat products in the first working mode of the conveying state control unit is greater than the single standard conveying quantity of meat products in the second working mode.

[0006] Furthermore, the first-level meat characteristic data includes the number of returned orders in a number of meat orders, the time taken to transport the meat products, the temperature during the transportation process, and the update delay time of the meat transportation data.

[0007] The secondary meat characteristic data include the proportion of returned orders in several meat orders, the linear fit between the time taken to transport meat products and the average temperature during the transportation of meat products, and the temperature rise rate during the transportation process.

[0008] Furthermore, the control module obtains the number of returned orders in a number of meat orders, and calculates the proportion of the number of returned orders in a number of meat orders.

[0009] If the proportion of the number of returned orders in the plurality of meat orders is greater than the preset second proportion, the control module controls the cold storage management unit to manage the meat products in the cold storage in a corresponding operation mode;

[0010] Among them, the corresponding operating mode is that the cold storage management unit manages the meat products in the cold storage with a first corresponding storage capacity, and the first corresponding storage capacity is determined by the difference between the proportion of the number of returns in several meat orders and a preset second proportion.

[0011] Furthermore, the calculation formula for the proportion of the number of returned orders in the plurality of meat orders is:

[0012] Among them, S is the proportion of returned orders among several meat orders, K is the number of returned orders among several meat orders, and T is the total number of meat orders.

[0013] Furthermore, if the proportion of the number of returned orders in the plurality of meat orders is greater than the preset first proportion and less than or equal to the preset second proportion, the control module respectively obtains the time taken to transport the meat products and the temperature during the transportation process, and calculates the linear fit between the time taken to transport the meat products and the average temperature during the transportation of the meat products.

[0014] If the linear fit between the time taken to transport the meat product and the average temperature during the transportation of the meat product is greater than a preset first fit and less than or equal to a preset second fit, the control module controls the conveying state control unit to control the conveying quantity of the meat product in the first working mode.

[0015] Furthermore, the first working mode is that the conveying state control unit controls the conveying quantity of the meat product with a first corresponding quantity, and the first corresponding quantity is determined by the difference between the linear fit of the time used to transport the meat product and the average temperature during the transportation of the meat product and a preset first fit.

[0016] Furthermore, if the linear fit between the time taken to transport the meat product and the average temperature during the transportation of the meat product is greater than the preset second fit, the control module obtains the update delay time of the meat transportation data,

[0017] If the update delay time of the meat delivery data is greater than the preset delay time, the control module determines the storage capacity ratio of the meat delivery data.

[0018] Furthermore, the storage capacity proportion of the meat transportation data is determined by the difference between the update delay time of the meat transportation data and the preset delay time.

[0019] Further, when the conveying state control unit completes the control of the conveying quantity of the meat product with the first corresponding quantity, the control module obtains the temperature of a single conveying cycle and calculates the temperature increase rate of the conveying process.

[0020] If the temperature increase rate during the transportation process is greater than a preset increase rate, the control module controls the conveying state control unit to control the conveying quantity of the meat product in a second working mode.

[0021] Furthermore, the second working mode is that the conveying state control unit controls the conveying quantity of the meat product with a second corresponding quantity, and the second corresponding quantity is re-determined by the difference between the temperature increase rate during the transportation process and the preset increase rate.

[0022] Compared with the prior art, the beneficial effects of the present invention are that, by setting a supply chain management module, a data acquisition module, a data processing module, a storage module and a control module, the present invention adjusts the maximum storage capacity of meat products according to the proportion of the number of returned orders in a number of meat orders, thereby reducing the influence of the stability of meat transportation caused by the change in the time of meat products in a non-insulated state due to the inaccurate adjustment of the maximum storage capacity of meat products, and by adjusting the single standard delivery quantity of meat products according to the linear fit between the time taken to transport the meat products and the average temperature during the transportation of the meat products, thereby reducing the insulation effect of the meat products caused by increased wear during transportation due to inaccurate adjustment of the single standard delivery quantity of meat products. By adjusting the storage capacity ratio of meat delivery data according to the update delay time of meat delivery data, the impact of the stability of meat supply caused by the surge in the number of orders due to the explosion of orders and thus the delay in data update is reduced. By making a secondary adjustment to the single standard delivery quantity of meat products according to the temperature rise rate of the transportation process, the impact of the stability of meat transportation caused by the excessive quantity of meat products, which leads to friction during transportation and the increase in temperature in the transportation box due to the inaccurate secondary adjustment of the single standard delivery quantity of meat products is reduced, thereby improving the stability of meat supply.

[0023] Furthermore, the system of the present invention adjusts the maximum storage capacity of meat products by setting the difference between the proportion of the number of returns in several meat orders and a preset second proportion, thereby reducing the impact of the decreased stability of meat transportation caused by changes in the length of time that meat products are in a non-insulated state, and further improving the stability of meat supply.

[0024] Furthermore, the system of the present invention adjusts the single standard delivery quantity of meat products by setting the difference between the linear fit of the time used to transport meat products and the average temperature during the transportation of meat products and a preset first fit, thereby reducing the impact of the stability of meat supply caused by the decrease in the insulation effect of meat products due to increased wear during transportation, thereby further improving the stability of meat supply.

[0025] Furthermore, the system of the present invention adjusts the storage capacity ratio of meat delivery data by setting the difference between the update delay time of meat delivery data and the preset delay time, thereby reducing the impact of the stability of meat supply caused by the delay in data update due to a surge in the number of orders, thereby further improving the stability of meat supply.

[0026] Furthermore, the system of the present invention performs secondary adjustment on the single standard delivery quantity of meat products by setting the difference between the temperature increase rate during the transportation process and the preset temperature increase rate, thereby reducing the impact of the excessive quantity of meat products, which causes friction during transportation and the subsequent increase in temperature in the transport box, which reduces the stability of meat transportation, thereby further improving the stability of meat supply.

[0035] See also Figure 1 , Figure 2 , Figure 3 as well as Figure 4 As shown, they are respectively the overall structural block diagram of the meat supply chain management system based on blockchain in an embodiment of the present invention, the specific structural block diagram of the supply chain management module, the connection structural block diagram of the supply chain management module and the data acquisition module, and the connection structural block diagram of the supply chain management module and the control module. A meat supply chain management system based on blockchain in the present invention comprises:

[0036] A supply chain management module, for controlling the operation status of the meat supply chain through blockchain, including a cold storage management unit for controlling the cold storage status, a delivery status control unit connected to the supply chain for controlling the operation status of the delivery node, and an order processing unit connected to the delivery status control unit for processing meat orders;

[0037] A data collection module, which is connected to the supply chain management module and is used to collect primary meat characteristic data;

[0038] A data processing module connected to the data acquisition module for analyzing and calculating the primary meat characteristic data to output secondary meat characteristic data;

[0039] A storage module, which is connected to the data acquisition module and the data processing module respectively, and is used to store the primary meat characteristic data and the secondary meat characteristic data respectively;

[0040] a control module, which is respectively connected to the supply chain management module, the data acquisition module, the data processing module and the storage module, and is used to determine the first working mode of the conveying state control unit according to the proportion of the number of returned orders in a number of meat orders and the linear fit between the time taken to transport the meat products and the average temperature during the transportation of the meat products, and to determine the proportion of the storage capacity of the meat conveying data according to the linear fit between the time taken to transport the meat products and the average temperature during the transportation of the meat products and the update delay time of the meat conveying data, and to determine the second working mode of the conveying state control unit according to the temperature rise rate during the transportation process;

[0041] Wherein, the single standard conveying quantity of meat products in the first working mode of the conveying state control unit is greater than the single standard conveying quantity of meat products in the second working mode.

[0042] Specifically, the linear fit between the time taken to transport meat products and the average temperature during the transportation of meat products is the degree of fit between the time taken to start transporting meat products to the destination and the average temperature of the storage space of meat products during transportation. Its specific meaning is that in a plane rectangular coordinate system with the time taken to transport meat products as the ordinate axis and the average temperature during the transportation of meat products as the abscissa axis, the time taken to transport meat products on several same transport routes is the ordinate, and several average temperatures during the transportation are the abscissa. The abscissa and the ordinate constitute several coordinate points in the plane rectangular coordinate system. According to MATLAB software performs a linear function fitting on the several coordinate points to obtain a linear function fitting image, then the variance of the straight-line distance between each coordinate point not on the linear function image and the linear function fitting function line and the proportion of the number of coordinate points not on the linear function image jointly reflect the degree of fitting. If the variance is smaller, it indicates that the linear correlation between the time used to transport the meat product and the average temperature during the transportation of the meat product is smaller. Similarly, the smaller the proportion of the number of coordinate points not on the linear function image, the higher the degree of fitting, and the greater the linear correlation between the time used to transport the meat product and the average temperature during the transportation of the meat product.

[0043] Specifically, the average temperature during the transportation of meat products is calculated as follows:

[0044] Among them, A is the average temperature during the transportation of meat products, B c is the temperature of the meat product storage space at the cth sampling moment, d is the number of samples, and d is a natural number greater than or equal to 1.

[0045] Specifically, the temperature rise rate during transportation is calculated as:

[0046] Among them, G is the temperature rise rate during the transportation process, E1 is the temperature of the meat product storage space at the initial moment in a single transportation cycle, E2 is the temperature of the meat product storage space at the end moment in a single transportation cycle, and T is the duration of a single transportation cycle.

[0047] Specifically, the maximum storage capacity of meat products means the maximum allowable storage capacity of meat products in a cold storage.

[0048] Specifically, the single standard delivery quantity of meat products means the maximum transportation quantity of meat products in a single transportation process.

[0049] Specifically, the calculation formula for the storage capacity ratio of meat delivery data is:

[0050] Among them, Z is the storage capacity ratio of meat transportation data, X is the storage space occupied by meat transportation data, and F is the total storage capacity of the database storing data.

[0051] Specifically, the meat delivery data includes the delivery temperature of the meat, the transportation time of the meat, and the delivery route of the meat.

[0052] The present invention provides a supply chain management module, a storage module and a control module, and adjusts the maximum storage capacity of meat products according to the proportion of the number of returned orders in a number of meat orders, thereby reducing the impact of the stability of meat transportation caused by the change in the time of meat products in a non-insulated state due to inaccurate adjustment of the maximum storage capacity of meat products. By adjusting the single standard delivery quantity of meat products according to the linear fit between the time used to transport the meat products and the average temperature during the transportation of the meat products, the impact of the stability of meat supply caused by the decrease in the insulation effect of meat products due to the increase in wear during transportation caused by inaccurate adjustment of the single standard delivery quantity of meat products is reduced. By adjusting the storage capacity ratio of meat delivery data according to the update delay time of meat delivery data, the impact of the stability of meat supply caused by the delay in data update due to the surge in the number of orders caused by the explosion of orders due to the inaccurate adjustment of the storage capacity ratio of meat delivery data is reduced. By making a secondary adjustment to the single standard delivery quantity of meat products according to the temperature rise rate of the transportation process, the impact of the stability of meat transportation caused by the excessive quantity of meat products, which leads to friction during transportation and the increase in temperature in the transportation box due to the inaccurate secondary adjustment of the single standard delivery quantity of meat products is reduced, thereby improving the stability of meat supply.

[0053] Please continue reading Figure 2As shown, the first-level meat characteristic data includes the number of returned orders in several meat orders, the time used to transport meat products, the temperature during the transportation process, and the update delay time of meat transportation data.

[0054] The secondary meat characteristic data include the proportion of returned orders in several meat orders, the linear fit between the time taken to transport meat products and the average temperature during the transportation of meat products, and the temperature rise rate during the transportation process.

[0055] Please continue reading Figure 2 As shown, the control module obtains the number of returned orders in a number of meat orders, and calculates the proportion of the number of returned orders in a number of meat orders.

[0056] If the proportion of the number of returned orders among the plurality of meat orders is greater than a preset first proportion, the control module determines that the stability of the meat supply is lower than an allowable range;

[0057] If the proportion of the number of returned orders in the plurality of meat orders is greater than the preset first proportion and less than or equal to the preset second proportion, the control module preliminarily determines that the stability of the transportation process is lower than the allowable range, and performs a secondary determination on the stability of the transportation process based on the linear fit between the time taken to transport the meat products and the average temperature during the transportation of the meat products;

[0058] If the proportion of the number of returned orders in the plurality of meat orders is greater than a preset second proportion, the control module controls the cold storage management unit to manage the meat products in the cold storage in a corresponding operation mode.

[0059] Specifically, the proportion of returned orders in several meat orders is recorded as Q, the preset first proportion is recorded as Q1, and Q1=0.3 is set, the preset second proportion is recorded as Q2, and Q2=0.4 is set, and the difference between the proportion of returned orders in several meat orders and the preset second proportion is recorded as △Q, and △Q=Q-Q2 is set.

[0060] The system of the present invention determines the stability of meat supply by setting a preset first ratio and a preset second ratio, thereby reducing the impact of decreased stability in meat transportation due to inaccurate determination of the stability of meat supply, and further improving the stability of meat supply.

[0061] Please continue reading Figure 2 As shown, the calculation formula for the proportion of returned orders in the aforementioned meat orders is:

[0062] Among them, S is the proportion of returned orders among several meat orders, K is the number of returned orders among several meat orders, and T is the total number of meat orders.

[0063] Please continue reading Figure 2As shown, the corresponding operating mode is that the cold storage management unit manages the meat products in the cold storage with a first corresponding storage capacity, and the first corresponding storage capacity is determined by the difference between the proportion of the number of returns in several meat orders and a preset second proportion.

[0064] Specifically, the specific process of determining the first corresponding storage capacity by the difference between the proportion of the number of returned orders in a number of meat orders and the preset second proportion is as follows:

[0065] The control module adjusts the maximum storage capacity of the meat product to the first storage capacity using the preset second storage capacity adjustment coefficient under the preset first proportion difference condition; the preset first proportion difference condition is that the difference between the proportion of the number of returned orders in a number of meat orders and the preset second proportion is less than or equal to the preset proportion difference;

[0066] The control module uses the preset first storage capacity adjustment coefficient to adjust the maximum storage capacity of the meat product to the second storage capacity under the preset second proportion difference condition; the preset second proportion difference condition is that the difference between the proportion of the number of returned orders in a number of meat orders and the preset second proportion is greater than the preset proportion difference;

[0067] Wherein, the preset first storage capacity adjustment coefficient is smaller than the preset second storage capacity adjustment coefficient.

[0068] Specifically, the first corresponding storage capacity includes the first storage capacity and the second storage capacity.

[0069] Specifically, the preset proportion difference is recorded as △Q0, and △Q0 is set to 0.1. The preset first storage capacity adjustment coefficient is recorded as α1, and α1 is set to 0.8. The preset second storage capacity adjustment coefficient is recorded as α2, and α2 is set to 0.9. The maximum storage capacity of meat products is recorded as V, wherein 0<α1<α2<1. The first corresponding storage capacity is recorded as V', and V'=V×(1+αi) / 2 is set, wherein αi is the preset i-th storage capacity adjustment coefficient, and i=1,2.

[0070] The system of the present invention adjusts the maximum storage capacity of meat products by setting the difference between the proportion of the number of returns in several meat orders and a preset second proportion, thereby reducing the impact of the stability of meat transportation caused by changes in the length of time that meat products are in a non-insulated state, and further improving the stability of meat supply.

[0071] Please continue reading Figure 2As shown, if the proportion of the number of returned orders in the several meat orders is greater than the preset first proportion and less than or equal to the preset second proportion, the control module respectively obtains the time used to transport the meat products and the temperature during the transportation process, and calculates the linear fit between the time used to transport the meat products and the average temperature during the transportation of the meat products.

[0072] If the linear fit between the time taken to transport the meat product and the average temperature during the transportation of the meat product is greater than a preset first fit, the control module secondly determines that the stability of the transportation process is lower than an allowable range;

[0073] If the linear fit between the time taken to transport the meat product and the average temperature during the transportation of the meat product is greater than a preset first fit and less than or equal to a preset second fit, the control module controls the transport state control unit to control the transport quantity of the meat product in the first working mode;

[0074] If the linear fit between the time taken to transport the meat product and the average temperature during the transportation of the meat product is greater than the preset second fit, the control module preliminarily determines that the real-time update of the meat transportation data is lower than the allowable range, and makes a secondary judgment on the real-time update of the meat transportation data based on the update delay time of the meat transportation data.

[0075] Specifically, the preset first fit is recorded as P1, and P1=0.4 is set. The preset second fit is recorded as P2, and P2=0.5. The linear fit between the time used to transport meat products and the average temperature during the transportation of meat products is recorded as P. The difference between the linear fit between the time used to transport meat products and the average temperature during the transportation of meat products and the preset first fit is recorded as △P, and △P=P-P1 is set.

[0076] The system of the present invention performs a secondary judgment on the stability of the conveying process by setting a preset first degree of fit and a preset second degree of fit, thereby reducing the impact of the decreased stability of the meat supply due to inaccurate secondary judgment on the stability of the conveying process, and further improving the stability of the meat supply.

[0077] Please continue reading Figure 2 As shown, the first working mode is that the conveying state control unit controls the conveying quantity of the meat product with a first corresponding quantity, and the first corresponding quantity is determined by the difference between the linear fit of the time used to transport the meat product and the average temperature during the transportation of the meat product and a preset first fit.

[0078] Specifically, the specific process of determining the first corresponding quantity by the difference between the linear fit between the time taken to transport the meat product and the average temperature during the transportation of the meat product and the preset first fit is:

[0079] The control module adjusts the single standard delivery quantity of the meat product to the first quantity using a preset first quantity adjustment coefficient under a preset first fit difference condition; the preset first fit difference condition is that the difference between the linear fit of the time taken to transport the meat product and the average temperature during the transportation of the meat product and the preset first fit is less than or equal to the preset fit difference;

[0080] The control module adjusts the single standard delivery quantity of the meat product to the second quantity using a preset second quantity adjustment coefficient under a preset second fit difference condition; the preset second fit difference condition is that the difference between the linear fit of the time taken to transport the meat product and the average temperature during the transportation of the meat product and the preset first fit is greater than the preset fit difference;

[0081] Wherein, the preset first quantity adjustment coefficient is smaller than the preset second quantity adjustment coefficient.

[0082] Specifically, the first corresponding quantity includes the first quantity and the second quantity.

[0083] Specifically, the preset fitting difference is recorded as △P0, and △P0 is set to 0.1. The preset first quantity adjustment coefficient is recorded as β1, and β1 is set to 1.2. The preset second quantity adjustment coefficient is recorded as β2, and β2 is set to 1.4. The single standard delivery quantity of meat products is recorded as H, where 1<β1<β2. The first corresponding quantity is recorded as H', and H'=H×(1+2βj) / 3 is set, where βj is the preset j-th quantity adjustment coefficient, and j=1,2.

[0084] The system of the present invention adjusts the single standard delivery quantity of meat products by setting the difference between the linear fit of the time used to transport meat products and the average temperature during the transportation of meat products and a preset first fit, thereby reducing the impact of the stability of meat supply caused by the decrease in the insulation effect of meat products due to increased wear during transportation, thereby further improving the stability of meat supply.

[0085] Please continue reading Figure 3 As shown, if the linear fit between the time taken to transport the meat product and the average temperature during the transportation of the meat product is greater than the preset second fit, the control module obtains the update delay time of the meat transportation data,

[0086] If the update delay time of the meat transportation data is greater than the preset delay time, the control module determines for the second time that the real-time performance of the meat transportation data update is lower than the allowable range, and determines the storage capacity ratio of the meat transportation data.

[0087] Specifically, the preset delay time is recorded as Y0, and Y0=0.04s is set. The update delay time of the meat transportation data is recorded as Y. The difference between the update delay time of the meat transportation data and the preset delay time is recorded as △Y, and △Y=Y-Y0 is set.

[0088] The system of the present invention performs a secondary determination on the real-time nature of meat delivery data updates by setting a preset delay time, thereby reducing the impact of decreased stability in meat supply due to inaccurate determination of the real-time nature of meat delivery data updates, and further improving the stability of meat supply.

[0089] Please continue reading Figure 3 As shown, the storage capacity ratio of the meat delivery data is determined by the difference between the update delay time of the meat delivery data and the preset delay time.

[0090] Specifically, the specific process of determining the storage capacity ratio of meat delivery data by the difference between the update delay time of meat delivery data and the preset delay time is as follows:

[0091] The control module uses a preset first proportion adjustment coefficient to adjust the storage capacity proportion of the meat delivery data to a first proportion under a preset first delay time difference condition; the preset first delay time difference condition is that the difference between the update delay time of the meat delivery data and the preset delay time is less than or equal to the preset delay time difference;

[0092] The control module uses a preset second proportion adjustment coefficient to adjust the storage capacity proportion of the meat delivery data to a second proportion under a preset second delay time difference condition; the preset second delay time difference condition is that the difference between the update delay time of the meat delivery data and the preset delay time is greater than the preset delay time difference;

[0093] Among them, the preset first proportion adjustment coefficient is smaller than the preset second proportion adjustment coefficient.

[0094] Specifically, the preset delay time difference is recorded as △Y0, and △Y0 is set to 0.01s. The preset first proportion adjustment coefficient is recorded as γ1, and γ1 is set to 1.1. The preset second proportion adjustment coefficient is recorded as γ2, and γ2 is set to 1.3. The storage capacity proportion of meat transportation data is recorded as L, wherein 1<γ1<γ2. The adjusted storage capacity proportion of meat transportation data is recorded as L', and L'=L×(1+3γm) / 4 is set, wherein γm is the preset wth proportion adjustment coefficient, and m=1,2.

[0095] The system of the present invention adjusts the storage capacity ratio of meat delivery data by setting the difference between the update delay time of meat delivery data and the preset delay time, thereby reducing the impact of the stability of meat supply caused by the delay in data update due to a surge in the number of orders, thereby further improving the stability of meat supply.

[0096] Please continue reading Figure 4 As shown, when the conveying state control unit completes the control of the conveying quantity of the meat product with the first corresponding quantity, the control module obtains the temperature of a single transport cycle and calculates the temperature increase rate of the transport process.

[0097] If the temperature increase rate during the transportation process is greater than the preset increase rate, the control module determines that the thermal insulation of the transportation process is lower than the allowable range, and controls the transportation state control unit to control the transportation quantity of the meat product in the second working mode.

[0098] Specifically, the preset increase rate is recorded as R0, and R0=2°C / h is set. The temperature increase rate during the transportation process is recorded as R. The difference between the temperature increase rate during the transportation process and the preset increase rate is recorded as △R, and △R=R-R0 is set.

[0099] The system of the present invention determines the thermal insulation during the transportation process by setting a preset increase rate, thereby reducing the impact of the stability of meat transportation caused by inaccurate determination of the thermal insulation during the transportation process, and further improving the stability of meat supply.

[0100] Please continue reading Figure 4 As shown, the second working mode is that the conveying state control unit controls the conveying quantity of the meat product with a second corresponding quantity, and the second corresponding quantity is re-determined by the difference between the temperature increase rate during the transportation process and the preset increase rate.

[0101] Specifically, the specific process of re-determining the second corresponding quantity by the difference between the temperature increase rate during the transportation process and the preset temperature increase rate is as follows:

[0102] The control module uses a preset fourth quantity secondary adjustment coefficient to secondary adjust the single standard delivery quantity of the meat product to a third quantity under a preset first increase rate difference condition; the preset first increase rate difference condition is that the difference between the temperature increase rate during the transportation process and the preset increase rate is less than or equal to the preset increase rate difference;

[0103] The control module uses a preset third quantity secondary adjustment coefficient to secondary adjust the single standard delivery quantity of the meat product to a fourth quantity under a preset second increase rate difference condition; the preset second increase rate difference condition is that the difference between the temperature increase rate during the transportation process and the preset increase rate is greater than the preset increase rate difference;

[0104] Among them, the preset third quantity secondary adjustment coefficient is smaller than the preset fourth quantity secondary adjustment coefficient.

[0105] Specifically, the second corresponding quantity includes the third quantity and the fourth quantity.

[0106] Specifically, the preset rising rate difference is recorded as △R0, and △R0 is set to 0.5℃ / h. The preset third quantity secondary adjustment coefficient is recorded as β3, and β3 is set to 0.7. The preset fourth quantity secondary adjustment coefficient is recorded as β4, and β4 is set to 0.8, wherein 0<β3<β4<1. The second corresponding quantity is recorded as H", and H”=H'×(1+2βw) / 3 is set. Among them, βw is the preset w-th quantity secondary adjustment coefficient, and w=3,4.

[0107] The system of the present invention performs secondary adjustment on the single standard delivery quantity of meat products by setting the difference between the temperature increase rate during the transportation process and the preset temperature increase rate, thereby reducing the impact of the excessive amount of meat products, which causes friction during transportation and the subsequent increase in temperature in the transport box, which causes a decrease in the stability of meat transportation, and further improves the stability of meat supply. Example 1

[0108] In this embodiment 1, the control module adjusts the maximum storage capacity of the meat products according to the difference between the proportion of the number of returned orders in a number of meat orders and a preset second proportion, wherein the preset proportion difference is recorded as △Q0, the preset first storage capacity adjustment coefficient is recorded as α1, the preset second storage capacity adjustment coefficient is recorded as α2, and the maximum storage capacity of the meat products is recorded as V, wherein 0<α1<α2<1, α1=0.8, α2=0.9, △Q0=0.1, and V=8t are set.

[0109] In this embodiment 1, ΔQ=0.2 is obtained, the control module determines that ΔQ>ΔQ0 and uses the preset first storage capacity adjustment coefficient to adjust the maximum storage capacity of the meat product to the second storage capacity, and calculates that V'=8t×(1+0.8) / 2=7.2t.
