Description

Technical Field

[0001] This invention relates to the field of material management technology, and more specifically, to a T10 material management system and method based on an RFID reader. Background Technology

[0002] RFID readers activate RFID tags within their operating range by emitting radio frequency signals at a specific frequency. Upon receiving the signal, the tag uses the energy gained from the induced current to transmit the information stored in its chip, or actively sends a signal at a specific frequency. The reader receives and decodes these signals, extracting the data from the tag and transmitting it to a central information system for further processing and analysis. The T10 Materials Management System is a software system specifically designed for enterprise resource planning. It primarily helps enterprises manage their materials-related affairs, including procurement, inventory management, and production planning. This system aims to improve operational efficiency, reduce costs, and ensure the rational utilization of materials.

[0003] Currently, when some frozen products enter the cold storage, product information needs to be marked. If the method of manually scanning and recording the materials step by step is adopted, it is not only inefficient, but also wastes a lot of manpower and resources. At the same time, frozen products need to be thawed before leaving the warehouse. Due to the influence of the external environment, the thawing time of the products is also changing. If the same thawing time is always used, it will reduce the quality of the products. Therefore, we propose a T10 material management system and method based on RFID readers. Summary of the Invention

[0004] The purpose of this invention is to provide a T10 material management system and method based on an RFID reader to solve the problems mentioned in the background art.

[0005] To address the aforementioned technical problems, one objective of this invention is to provide a T10 material management system based on an RFID reader, comprising an RFID tag management module, an RFID reading management module, a material detection module, an inventory management module, a data storage module, and a display module.

[0006] When materials are put into storage, the RFID tag management module writes relevant data of the materials into the tag, including storage time, production date, storage location information and thawing time information when they are taken out. After the tag is generated, it checks whether the tag can work properly, and then binds it to the materials and stores them in the designated location in the refrigerator.

[0007] The RFID reader in the RFID reading management module emits radio frequency signals. When the RFID tag moves into the range of the radio frequency signal, it will activate the internal chip circuit of the RFID tag and send the information stored in the RFID tag to the RFID reading management module through the radio frequency signal to read the information stored in the tag.

[0008] The inventory management module identifies RFID tags through the RFID reader in the RFID reading management module, records the entry and exit information of materials, identifies RFID tags in the inventory by adjusting the range of the radio frequency signal emitted by the RFID reader, takes stock of the types and quantities of materials in the warehouse, issues replenishment warnings for products whose material quantities are below the warning line, and issues disposal warnings for products whose material information in the RFID tags is about to expire.

[0009] When the product is thawed in advance, the material detection module monitors the thawing status of the product in real time through a non-contact sensor network. If the thawing time of the product is different from the time recorded in the RFID tag, the real-time monitored thawing time information is transmitted to the data storage module for storage. If the thawing time is different from the thawing time information recorded in the RFID tag for three consecutive times, a change signal is transmitted to the RFID tag management module to change the thawing time information in the RFID tag.

[0010] The data storage module is used to store the thawing time information transmitted by the material inspection module, as well as the material entry and exit information of the inventory management module, and to store the warehouse log information.

[0011] The display module is used to display product information within the RFID tag and, through the search function, quickly retrieve the corresponding RFID tag to locate the product.

[0012] Preferably, the RFID tag management module includes a tag generation unit and a tag detection unit. The tag generation unit writes the basic data of the materials into the tag to generate an RFID tag, and uses an ultra-high frequency communication protocol to establish a communication channel between the RFID tag and the RFID reader. The communication frequency of the ultra-high frequency communication protocol is between 860MHz and 960MHz, which has the advantages of long reading distance, fast identification speed, and the ability to identify a large number of tags at the same time. It can meet the needs of fast and accurate identification of items in large-scale logistics transportation and warehousing management.

[0013] The tag detection unit uses a network analyzer to detect parameters such as impedance, reflection coefficient, and transmission coefficient of the RFID tag. If the measurement results meet the design requirements of the tag, it indicates that the tag has good performance and can effectively receive and transmit radio frequency signals.

[0014] Preferably, when the tag generation unit writes data into the RFID tag, it uses Manchester encoding, where a negative transition in half a bit period represents binary "1" and a positive transition in half a bit period represents binary "0". Load modulation or backscatter modulation of the load wave is used. When the RFID tag and the RFID reader transmit data, it is helpful to detect errors in the data transmission, and the receiving end can use the transition as a synchronization clock.

[0015] Preferably, the inventory management module includes an inbound / outbound management unit, an inventory counting unit, and an inventory early warning unit. The inbound / outbound management unit uses an RFID reader to identify the RFID tags bound to the materials, records the outbound and inbound information of the materials, sorts the products according to their inbound time, and outbounds them in the order of inbound to ensure first-in, first-out.

[0016] The inventory counting unit expands the range of the RFID reader's radio frequency signal transmission, activates RFID tags in the warehouse, counts the types and quantities of products in the warehouse, generates a daily log, generates a replenishment signal for products whose inventory is below the warning quantity, generates a discard signal for products whose shelf life has exceeded the expiration date, and transmits the signal to the inventory warning unit.

[0017] The inventory early warning unit receives replenishment and disposal signals from the inventory counting unit, and sends blue replenishment warnings and red disposal warnings to the display module to remind staff to replenish or discard products.

[0018] Preferably, when implementing first-in-first-out, the inbound / outbound management unit adopts a queue data structure, which is a linear list that only allows insertion operations (enqueueing) at one end and deletion operations (dequeueing) at the other end, just like queuing in life, where the first person to arrive receives service first, and the last person to arrive receives service later.

[0019] Preferably, when the inventory counting unit stores the logs for the day, it stores the logs in a non-relational database. Non-relational databases can adapt to different data structures and formats and do not require pre-defining a strict data model.

[0020] Preferably, the material detection module includes a sensor detection unit, which uses multiple non-contact sensors to detect the temperature around the thawing product, thereby determining the thawing status of the product and recording the corresponding thawing time.

[0021] Preferably, the display module includes an MMS display panel and a tag search unit. The MMS display panel is used to display the data information in the RFID tag and to display information such as the location, status, and transportation progress of the goods, so as to track the flow of goods in real time and improve the efficiency and accuracy of logistics management.

[0022] The tag finding unit is used to retrieve RFID tag information throughout the warehouse, and retrieve the corresponding RFID tag based on product-related information to achieve rapid product location.

[0023] Preferably, the tag search unit uses a keyword search method. When a user enters a keyword to search, the search system will quickly locate the data item containing the keyword according to the index. Then, the search system will search for the record that matches the keyword in the index and return the relevant data item to retrieve the corresponding RFID tag information.

[0024] The second objective of this invention is to provide a T10 material management method based on an RFID reader, including the T10 material management system based on an RFID reader as described in any one of the above-mentioned methods, comprising the following steps:

[0025] S1. Write the data information of the materials into the RFID tag through the RFID tag management module, and establish a communication connection with the RFID reader in the RFID reading management module.

[0026] S2. The inventory management module uses an RFID reader to identify RFID tags, records the entry and exit information of materials, generates the daily log, and issues corresponding replenishment and disposal warnings.

[0027] S3. Use the material detection module to monitor the thawing status of the thawing product. If the thawing time is different from the thawing time information recorded in the RFID tag for three consecutive times, then send a change signal to the RFID tag management module to change the thawing time information in the RFID tag.

[0028] S4. The data storage module stores RFID tag information and thawing time information, and the display module displays product information within the RFID tag, as well as a search function.

[0029] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0030] The T10 material management system, based on RFID readers, writes material data into RFID tags through an RFID tag management module. The RFID tags record the material's entry time, production date, storage location, and thawing time upon retrieval. A communication link is established with the RFID reader within the RFID reading management module. The inventory management module uses the RFID reader to identify the RFID tags, recording material entry and exit information and generating a daily log. Simultaneously, it issues replenishment warnings for products with quantities below the warning threshold and discard warnings for products whose RFID tag information indicates they are about to expire. This enables statistical analysis of warehouse product quantities, improving the accuracy and efficiency of inventory management, reducing inventory costs, and enhancing the company's competitiveness.

[0031] Multiple non-contact sensors within the material detection module are used to detect the temperature around the thawing product, thereby determining the thawing status and recording the corresponding thawing time. If the thawing time differs from the thawing time recorded in the RFID tag three times consecutively, a change signal is sent to the RFID tag management module to update the thawing time information in the RFID tag. This enables real-time adjustment of the thawing time of frozen products, saving resources, accelerating the product outbound speed, and ensuring the quality of outbound products.

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0040] RFID readers activate RFID tags within their operating range by emitting radio frequency signals at a specific frequency. Upon receiving the signal, the tag uses the energy gained from the induced current to transmit the information stored in its chip, or actively sends a signal at a specific frequency. The reader receives and decodes these signals, extracting the data from the tag and transmitting it to a central information system for further processing and analysis. The T10 Materials Management System is a software system specifically designed for enterprise resource planning. It primarily helps enterprises manage their materials-related affairs, including procurement, inventory management, and production planning. This system aims to improve operational efficiency, reduce costs, and ensure the rational utilization of materials.

[0041] like Figure 1 As shown, one of the objectives of this invention is to provide a T10 material management system based on an RFID reader, including an RFID tag management module 100, an RFID reading management module 200, a material detection module 400, an inventory management module 300, a data storage module 500, and a display module 600.

[0042] When materials are put into storage, the RFID tag management module 100 writes relevant data of the materials into the tag, including the storage time, production date, storage location information and thawing time information when they are taken out. After the tag is generated, it is checked whether the tag can work properly, and then it is bound to the materials and stored in the designated location in the refrigerator.

[0043] The RFID reader in the RFID reading management module 200 emits radio frequency signals. When the RFID tag moves into the range of the radio frequency signal, the internal chip circuit of the RFID tag will be activated, and the information stored in the RFID tag will be sent to the RFID reading management module 200 through the radio frequency signal to read the information stored in the tag.

[0044] The inventory management module 300 identifies RFID tags through the RFID reader in the RFID reading management module 200, records the entry and exit information of materials, and identifies RFID tags in the inventory by adjusting the range of the radio frequency signal emitted by the RFID reader. It also conducts inventory checks on the types and quantities of materials in the warehouse, issues replenishment warnings for products whose material quantities are below the warning line, and issues disposal warnings for products whose material information in the RFID tags is about to expire.

[0045] When the product is thawed in advance, the material detection module 400 monitors the thawing status of the product in real time through a non-contact sensor network. If the thawing time of the product is different from the time recorded in the RFID tag, the real-time monitored thawing time information is transmitted to the data storage module 500 for storage. If the thawing time is different from the thawing time information recorded in the RFID tag for three consecutive times, a change signal is transmitted to the RFID tag management module 100 to change the thawing time information in the RFID tag.

[0046] The data storage module 500 stores the thawing time information transmitted by the material detection module 400, as well as the material entry and exit information of the inventory management module 300, and stores the warehouse log information.

[0047] The display module 600 displays product information within the RFID tag, and the search function allows for quick retrieval of the corresponding RFID tag to locate the product.

[0048] like Figure 2 As shown, the RFID tag management module 100 includes a tag generation unit 110 and a tag detection unit 120. The tag generation unit 110 writes the basic data of the materials into the tag to generate an RFID tag, and uses an ultra-high frequency communication protocol to establish a communication channel between the RFID tag and the RFID reader. The communication frequency of the ultra-high frequency communication protocol is between 860MHz and 960MHz, which has the advantages of long reading distance, fast identification speed, and the ability to identify a large number of tags at the same time. It can meet the needs of fast and accurate identification of items in large-scale logistics transportation and warehouse management.

[0049] The RFID reader emits a specific ultra-high frequency signal, typically between 860MHz and 960MHz. This signal contains instructions and energy, forming an electromagnetic field in space that covers a certain area. When an RFID tag enters the signal coverage area of ​​the RFID reader, it receives the radio frequency signal emitted by the reader, acquires energy, activates the internal chip circuitry, and reflects the information stored in the chip back to the RFID reader as a radio frequency signal through the antenna. Simultaneously, the reader demodulates and decodes the received signal to extract the information stored in the RFID tag.

[0050] The tag detection unit 120 uses a network analyzer to detect parameters such as impedance, reflection coefficient, and transmission coefficient of the RFID tag. If the measurement results meet the design requirements of the tag, it indicates that the tag has good performance and can effectively receive and transmit radio frequency signals.

[0051] To ensure error-free data transmission within the RFID tag, the tag generation unit 110 employs Manchester encoding when writing data into the RFID tag. A negative transition within half a bit cycle represents a binary "1," and a positive transition within half a bit cycle represents a binary "0." Load modulation or backscatter modulation is used. This facilitates error detection during data transmission between the RFID tag and the RFID reader, and the receiver can use the transitions as a synchronization clock to accurately determine data bit boundaries, thus reducing the bit error rate. Even under signal interference or attenuation, the receiver can still recover the data by detecting level transitions. Furthermore, each bit of Manchester-encoded data contains two level changes, resulting in a richer signal spectrum and stronger anti-interference capabilities.

[0052] like Figure 3 As shown, the inventory management module 300 includes an inbound / outbound management unit 310, an inventory counting unit 320, and an inventory early warning unit 330. The inbound / outbound management unit 310 uses an RFID reader to identify the RFID tags attached to the materials, records the outbound and inbound information of the materials, sorts the products according to their inbound time, and carries out outbound products in the order of inbound to ensure first-in, first-out.

[0053] The inventory counting unit 320 expands the range of the RFID reader's radio frequency signal transmission, activates RFID tags in the warehouse, counts the types and quantities of products in the warehouse, and generates a daily log. At the same time, it generates a replenishment signal for products whose inventory quantity is lower than the warning quantity, generates a discard signal for products whose shelf life has exceeded the expiration date, and transmits the signal to the inventory warning unit 330.

[0054] The inventory early warning unit 330 receives the replenishment signal and the disposal signal transmitted by the inventory counting unit 320, and sends a blue replenishment warning and a red disposal warning to the display module 600 to remind the staff to replenish or discard the products.

[0055] To ensure the first-in, first-out (FIFO) principle for product entry and exit, the inbound / outbound management unit 310 uses a queue data structure, a linear list that allows insertion (enqueueing) at one end and deletion (dequeueing) at the other end, just like queuing in real life, where those who arrive first receive service first, and those who arrive later receive service later.

[0056] A queue is a special linear list data structure that follows the First-In, First-Out (FIFO) principle. For the enqueue operation, suppose there is an initially empty queue, and elements 1, 2, and 3 are enqueued sequentially. First, element 1 is added to the rear of the queue; at this point, both the front and rear of the queue point to element 1. Next, element 2 is enqueued, and the rear of the queue moves one position to the right to point to element 2. Finally, element 3 is enqueued, and the rear of the queue moves again to point to element 3. For a queue already containing elements 1, 2, and 3, a dequeue operation is performed. First, element 1, which was pointed to by the front of the queue, is removed, and the front of the queue moves one position to the right to point to element 2. Then, element 2 is dequeued again, and the front of the queue continues to move to point to element 3, thus achieving the FIFO principle.

[0057] To better store the daily logs of the warehouse, the inventory counting unit 320 stores the logs of the day in a non-relational database. Non-relational databases can adapt to different data structures and formats, without the need to predefine a strict data schema. The structure of the log data is determined according to the log requirements of the day, and the functions of index support and query language are expanded to facilitate the detection and query of logs.

[0058] The material detection module 400 includes a sensor detection unit 410. The sensor detection unit 410 uses multiple non-contact sensors to detect the temperature around the thawing product, thereby determining the thawing status of the product and recording the corresponding thawing time. The infrared detector converts the received infrared radiation into an electrical signal. The signal processing circuit amplifies, filters, and processes the electrical signal, and finally outputs an electrical signal or digital signal corresponding to the measured temperature.

[0059] Any object above absolute zero emits infrared radiation, and the amount of radiation energy is related to the object's temperature. Infrared temperature sensors determine the temperature of an object by measuring the infrared radiation energy emitted by the object.

[0060] like Figure 4 As shown, the display module 600 includes an MMS display board 610 and a tag finding unit 620. The MMS display board 610 is used to display the data information in the RFID tag and display information such as the location, status, and transportation progress of the goods, so as to track the flow of goods in real time and improve the efficiency and accuracy of logistics management.

[0061] The tag lookup unit 620 is used to retrieve RFID tag information throughout the warehouse, and retrieves the corresponding RFID tag based on product-related information to achieve rapid product location.

[0062] In order to better retrieve RFID tag information, the tag search unit 620 adopts a keyword search method. When the user enters a keyword to search, the search system will quickly locate the data item containing the keyword according to the index. Then, the search system will search for the record matching the keyword in the index and return the relevant data item to retrieve the corresponding RFID tag information.

[0063] First, users determine keywords based on their needs to accurately locate targets during the search process. Second, in the tag lookup unit 620, an index can be created for relevant information of each tag (such as tag ID, description, attributes, etc.) to quickly find specific tags based on keywords. When a user enters keywords for a search, the retrieval system quickly locates data items containing those keywords based on the index. The retrieval system analyzes and processes the input keywords, removing stop words and performing stemming operations to improve search accuracy. Then, the retrieval system searches the index for records matching the keywords and returns the relevant data items. If there are multiple keywords, they can be combined using logical operators (such as AND, OR, NOT) to further narrow or broaden the search scope until the corresponding RFID tag information is retrieved. Workers use the tag lookup unit 620 to locate products to RFID tags and obtain the corresponding product's location information, unfreezing information, and other basic information from the RFID tags.

[0064] like Figure 5 As shown, a second objective of this invention is to provide a T10 material management method based on an RFID reader, including any of the above-mentioned T10 material management systems based on RFID readers, comprising the following steps:

[0065] S1. The data information of the materials is written into the RFID tag through the RFID tag management module 100, and a communication connection is established with the RFID reader in the RFID reading management module 200.

[0066] S2, Inventory Management Module 300 uses an RFID reader to identify RFID tags, records the entry and exit information of materials, generates the daily log, and issues corresponding replenishment and disposal warnings.

[0067] S3. The material detection module 400 monitors the thawing status of the thawing product. If the thawing time is different from the thawing time information recorded in the RFID tag for three consecutive times, a change signal is transmitted to the RFID tag management module 100 to change the thawing time information in the RFID tag.

[0068] S4. The data storage module 500 stores the RFID tag information and the thawing time information, and the display module 600 displays the product information in the RFID tag, as well as the search function.

[0069] In summary, this T10 material management system based on RFID readers writes material data into RFID tags through the RFID tag management module 100. The RFID tags record the material's entry time, production date, storage location, and thawing time upon retrieval. They also establish communication with the RFID reader in the RFID reading management module 200. The inventory management module 300 uses the RFID reader to identify the RFID tags, recording the material's entry and exit information and generating a daily log. Simultaneously, it issues replenishment warnings for products with quantities below the warning threshold and alerts products whose RFID tag information is about to expire. The system issues a waste warning, enables the counting of products in the warehouse, improves the accuracy and efficiency of inventory management, reduces inventory costs, and enhances the company's competitiveness. Multiple non-contact sensors within the material detection module 400 detect the temperature around the thawing products, thereby determining the thawing status and recording the corresponding thawing time. If three consecutive thawing times differ from the thawing time recorded in the RFID tag, a change signal is transmitted to the RFID tag management module 100 to update the thawing time information in the RFID tag. This allows for real-time adjustment of the thawing time of frozen products, saving resources, accelerating product outbound speed, and ensuring product outbound quality.

[0070] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed.
