Technical Field

[0001] The present application relates to the technical field of processing systems or methods for monitoring purposes, and in particular to a product supply chain tracking method and a system. Background Art

[0002] Supply chain refers to the chain of activities in the entire process of product production, transportation and sales during the production and circulation process, including suppliers, distribution centers, warehouses, etc. The existing supply chain involves multiple links. When a problem occurs in a link, it is difficult for companies to track the problematic link of the product. If they want to understand the problematic link of the product, they need to make complicated inquiries to upstream or downstream companies, and at the same time, they cannot meet the efficiency and accuracy of product process tracking.

[0003] In the prior art, the publication date is January 31, 2023, the publication number is CN115660295A, and the name is a supply chain management method and system for the entire life cycle of a product, which discloses: after the nodes of the enterprises participating in the product supply chain are sorted, they are determined as blockchain nodes; the business information data of the enterprise is pre-processed, stored in the enterprise's blockchain, and backed up to the blockchain of all participating enterprises; the enterprise's reputation value is calculated based on the company's historical production data and the historical order data of upstream and downstream enterprises; the production data of the enterprise is monitored in real time, and if the deviation between the production data and the production plan data exceeds the preset value, it is judged as an abnormal project; the abnormal information of the abnormal project is extracted, and the risk level of the abnormal project is calculated, and the abnormal project, abnormal data and risk level are stored in the enterprise's blockchain in an associated manner, and sent to the enterprise and the upstream and downstream enterprises of the abnormal project.

[0004] The above technical solutions solve the problem of not being able to track product progress at any time and not being able to obtain abnormal conditions of other nodes in a timely manner.

[0029] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

[0030] This embodiment provides a product supply chain tracking method and system. Figure 1-2 Describe them together.

[0031] Example

[0032] Product process tracking often requires the combination of blockchain technology, but blockchain technology cannot achieve fast tracking. Its characteristics tend to lock and save data information. Enterprises often need to quickly identify problem links for product tracking, which requires optimization in identification speed. In other words, it is very important to quickly and accurately locate the problem link of the product.

[0033] This embodiment provides a product supply chain tracking method, which is executed by a controller. It can be understood that when the controller executes the method, it will perform control according to the logical order of the method.

[0034] refer to Figure 1 , the method specifically comprises:

[0035] Based on the global positioning system and the RFID tag of the purchasing place, the real location of the purchasing place is determined; the raw material purchasing information of the purchasing place is obtained, and a raw material information data set of the purchasing place is established; the product purchasing time T1 of the purchasing place and the time T2 when the product arrives at the source manufacturer are obtained, and a difference operation is performed on T2 and T1 to obtain a first difference set ω1; the freight end receiving time T3 and the freight end delivery time T4 are obtained, and a difference operation is performed on T4 and T2 as well as T3 and T1 to obtain a second difference set ω2; the product warehousing time T5 is obtained, and a difference operation is performed on T5 and T1 to obtain a fourth difference set ω4; the first difference set ω1, the second difference set ω2, the third difference set ω3 and the fourth difference set ω4 are used as difference factors to determine the difference qualification rate.

[0036] Among them, in some embodiments, performing a difference operation on T2 and T1 to obtain a first difference set ω1 specifically includes: tracing the products corresponding to the unqualified difference, marking the products corresponding to the unqualified difference as label A, and a plurality of labels A are set as the first difference set ω1. It can be understood that the first difference set ω1 is composed of a plurality of unqualified labels A, that is, each time a product with an unqualified difference appears, a label A will be added. It should be noted that the unqualified difference here refers to the interval between the purchase time T1 of the product at the purchase place and the time T2 when the product arrives at the source manufacturer does not meet the time interval specified by the enterprise. Then, the problem link of the product exists here.

[0037] In some embodiments, difference operations are performed on T4 and T2, and on T3 and T1 to obtain a second difference set ω2 and a third difference set ω3, specifically including: tracing the unqualified differences between T4 and T2, marking the products corresponding to the unqualified differences with label B, and a plurality of label Bs are set as the second difference set ω2; tracing the unqualified differences between T3 and T1, marking the products corresponding to the unqualified differences with label C, and a plurality of label Cs are set as the third difference set ω3. It is understandable that the second difference set ω2 is composed of multiple unqualified labels B, that is, each time a product with unqualified difference appears, a label B will be added. It should be noted that the unqualified difference here refers to the fact that the interval between the delivery time T4 at the freight end and the time T2 at the source manufacturer does not meet the time interval specified by the enterprise. In this case, the problem link of the product exists here; similarly, it is understandable that the third difference set ω3 is composed of multiple unqualified labels C, that is, each time a product with unqualified difference appears, a label C will be added. It should be noted that the unqualified difference here refers to the fact that the interval between the delivery time T3 at the freight end and the product purchase time T1 at the purchasing location does not meet the time interval specified by the enterprise. In this case, the problem link of the product exists here.

[0038] In some embodiments, the product entry time T5 is obtained, and a difference operation is performed on T5 and T1 to obtain a fourth difference set ω4, which specifically includes: tracing the product corresponding to the unqualified difference, marking the product corresponding to the unqualified difference as a label D, and a plurality of labels D are set as the fourth difference set ω4. It can be understood that the fourth difference set ω4 is composed of a plurality of unqualified labels D, that is, each time a product with an unqualified difference appears, a label D will be added. It should be noted that the unqualified difference here refers to the interval between the acquisition of the product entry time T5 and the product purchase time T1 at the purchase location does not meet the time interval specified by the enterprise, so the problem link of the product exists here.

[0039] In some embodiments, the first difference set ω1, the second difference set ω2, the third difference set ω3 and the fourth difference set ω4 are used as difference factors to determine the difference qualified rate, which specifically includes: substituting the first difference set ω1, the second difference set ω2, the third difference set ω3 and the fourth difference set ω4 into the following formula for calculation:

[0040]

[0041] Among them, μ is the difference qualified rate; ω n is the nth difference set; ω (n，标准) is the standard deviation set of the nth difference set.

[0042] It should be noted that when the aforementioned ω1, ω2, ω3, and ω4 are all abnormal, the aforementioned are substituted into the above formula and compared with the corresponding standard difference value sets. When the difference pass rate μ is equal to 100%, it means that the difference set is qualified relative to the other difference sets; when the difference pass rate μ is less than 100% but greater than 50%, it means that the difference set is also qualified relative to the other difference sets; when the difference pass rate μ is less than 50%, it means that the difference set is unqualified relative to the other difference sets. At this time, according to the difference pass rate, it can be obtained which link has a problem, and then tracking can be achieved.

[0043] The method of this embodiment can realize the tracking of product supply chains in two scenarios. One is the tracking of a single problematic link, and the other is the tracking of key problematic links when problems occur in multiple links. It is applicable to more scenarios and meets a variety of possible needs. The economic cost is low during the tracking process, the tracking speed is fast, and the accuracy of the tracking results is relatively high.

[0047] The calculation module is used to use the first difference set ω1, the second difference set ω2, the third difference set ω3 and the fourth difference set ω4 as difference factors to determine the difference qualified rate.

[0048] In some embodiments, the controller is data-connected to the positioning module, the acquisition module, and the calculation module, and the controller independently controls the positioning module, the acquisition module, and the calculation module.

[0049] It should be noted that the system is controlled as a whole by the controller, wherein the positioning module is first controlled to execute based on the global positioning system and the RFID tag of the purchasing place to determine the real location of the purchasing place, and then the controller controls the acquisition module to execute the acquisition of the purchasing place's raw material information and establish the purchasing place's raw material information data set; obtain the purchasing time T1 of the purchasing place's product and the time T2 when the product arrives at the source manufacturer, perform a difference operation on T2 and T1, and obtain the first difference set ω1; obtain the freight terminal's receiving time T3 and the freight terminal's delivery time T4, perform a difference operation on T4 and T2 and T3 and T1, and obtain the second difference set ω2; obtain the product's warehousing time T5, perform a difference operation on T5 and T1, and obtain the fourth difference set ω4. After the acquisition module is executed, the controller controls the calculation module to use the first difference set ω1, the second difference set ω2, the third difference set ω3 and the fourth difference set ω4 as difference factors to determine the difference qualification rate. Subsequently, the system completes the overall operation.

[0050] At the same time, it should be understood that the system can be divided into one or more modules, one or more modules are stored in the memory and executed by the controller to complete the method of this embodiment. One or more modules can be a series of computer program instruction segments that can complete specific functions, and the instruction segments are used to describe the execution process of the computer system in the terminal device.
