Description

Technical Field

[0001] This invention relates to the field of data processing technology, and in particular to an RFID-based intelligent shelf inventory management method and system. Background Technology

[0002] Currently, traditional cargo management methods face numerous challenges in modern logistics warehousing systems.

[0003] In traditional logistics and warehousing systems, the receipt, dispatch, and management of goods largely rely on manual operations. For example, in a large retail warehouse, staff need to manually record the arrival information of goods, find suitable storage locations on the shelves, and verify the information again when goods are dispatched. This manual operation method is inefficient, especially during peak periods with large order volumes. Moreover, due to the large warehouse area and the variety of goods, this inventory method cannot reflect the true inventory situation in real time, nor can it effectively manage goods in all aspects, wasting a lot of manpower and resources.

[0004] Therefore, in order to overcome the above-mentioned defects, the present invention provides a method and system for managing goods on an intelligent shelf. Summary of the Invention

[0005] This invention provides an RFID-based intelligent shelf inventory management method and system. By acquiring and analyzing inventory information from various areas of the intelligent shelf, it automatically generates corresponding replenishment plans when replenishment is needed, ensuring the continuity of product supply. Secondly, during replenishment operations, it can identify and plan the storage and warehousing of items, ensuring the accuracy of item placement, efficiency of warehousing, and maximizing the utilization of intelligent shelf space. Simultaneously, it can monitor the outbound behavior of items on the intelligent shelf in real time. Finally, when outbound items are detected, the payment status of the items is tracked to ensure that items are only effectively released after successful settlement, preventing theft. Furthermore, the inventory information on the intelligent shelf is updated promptly after outbound shipment, achieving comprehensive and effective management of goods on the intelligent shelf. This saves significant manpower and resources while improving the efficiency of goods management.

[0006] This invention provides an RFID-based intelligent shelf inventory management method, comprising:

[0007] Step 1: Obtain inventory information for each area on the smart shelf based on sensors, and generate a replenishment plan when the inventory is below the safety level;

[0008] Step 2: Based on the replenishment plan, identify and plan the warehousing and storage of replenishment items using RFID, and carry out the warehousing operation of replenishment items based on the identification and warehousing and storage plan. At the same time, monitor the outbound operation of items in real time.

[0009] Step 3: Track the payment status of items based on the outbound operation, and automatically update the inventory information of each area on the smart shelf after successful payment.

[0010] Preferably, in an RFID-based smart shelf inventory management method, step 1 involves acquiring inventory information for each area of ​​the smart shelf based on sensors, including:

[0011] The management terminal performs real-time parallel monitoring and control of sensors deployed in various areas of the smart shelf, and obtains multi-dimensional information on the storage of items in various areas of the smart shelf based on the results of the parallel monitoring and control.

[0012] Based on the sensors, the multi-dimensional item storage information of items in each area is transmitted back to the management terminal, and the item storage information under each dimension is independently analyzed based on the management terminal to obtain the item inventory status under each dimension.

[0013] The inventory status of items under different dimensions is correlated from multiple perspectives, and the inventory information of items in each area of ​​the smart shelf is obtained based on the results of the multi-angle correlation.

[0014] Preferably, in an RFID-based smart shelf inventory management method, step 1 involves generating a replenishment plan when the inventory falls below a safety level, including:

[0015] The obtained inventory information is quantified to obtain the inventory quantity of items in each area of ​​the smart shelf;

[0016] The system acquires the periodic turnover data of items in each area of ​​the smart shelf based on the management terminal, and determines the demand trend of items in each area based on the periodic turnover data.

[0017] Based on demand trends and the full load of items in each area of ​​the smart shelf, the safety level of inventory in each area of ​​the smart shelf is determined, and the inventory of items in each area is compared with the corresponding safety level in real time.

[0018] When the inventory of goods is less than the corresponding safety level, the replenishment quantity and location of goods for each region are determined based on the comparison results, and a replenishment plan is generated based on the replenishment quantity and location.

[0019] Preferably, an RFID-based smart shelf inventory management method generates a replenishment plan based on the replenishment quantity and location of items, including:

[0020] Obtain the replenishment plan and determine the multiple notification terminals corresponding to the replenishment plan based on management needs;

[0021] Determine the mapping management relationship between different notification terminals and each area on the smart shelf, and divide the replenishment plan for different areas on the smart shelf into main categories based on the mapping management relationship;

[0022] Based on the subject segmentation results, the local notification terminals corresponding to the replenishment plans of each region are obtained, and the replenishment plans are sent to the corresponding local notification terminals in parallel for notification and publicity.

[0023] Preferably, in a smart shelf inventory management method based on RFID, step 2 involves identifying replenishment items and planning their warehousing based on RFID according to a replenishment plan, and then performing warehousing operations on the replenishment items based on the identification and warehousing scheduling plan, including:

[0024] Based on the replenishment plan, the corresponding replenishment items are retrieved, and the target frequency radio frequency signal is transmitted to the surrounding area based on the RFID reader;

[0025] The RFID reader responds to the radio frequency signal based on the tag attached to the replenishment item, and returns the replenishment item information stored in the tag to the RFID reader based on the modulated radio frequency signal. The reader also demodulates and decodes the received modulated radio frequency signal to obtain the basic item information of the replenishment item.

[0026] Perform a global traversal of the existing items in each area of ​​the smart shelf, and obtain the actual storage status of various items on the smart shelf based on the global traversal results;

[0027] Based on the actual storage status, determine the slow-moving characteristics and hot-moving characteristics of items in each area of ​​the smart shelf, as well as the space utilization rate of each area. At the same time, determine the location distribution of each area on the smart shelf, and determine the complexity of item entry and exit from different areas based on the location distribution.

[0028] Based on space utilization, the space allocation of each area on the smart shelf is adjusted, and based on the space allocation adjustment results, the existing items are first scheduled according to the characteristics of slow-moving goods, hot-moving goods and the complexity of the entry and exit of items in different areas. Based on the first scheduling results, the current item placement attributes in different areas are determined.

[0029] The system performs similarity matching between the item placement attributes and the basic item information of the replenishment items, and determines the effective placement position for the replenishment items based on the similarity matching results.

[0030] The effective placement locations are fixed on the smart shelf, and the relative positional relationship between the effective placement locations and other areas is determined based on the fixed location results.

[0031] The optimal scheduling path for replenishment items is determined based on their relative positions, and a second scheduling is performed on the replenishment items in parallel based on the optimal scheduling path.

[0032] Based on the second scheduling result, the replenishment items are put into storage.

[0033] Preferably, an RFID-based smart shelf inventory management method, which performs warehousing operations on replenishment items based on a second scheduling result, includes:

[0034] Based on the inbound operation, the basic item information of the replenishment items in each area of ​​the smart shelf is classified by region, and the basic item information of the replenishment items in each region is split into multiple dimensions based on the region classification results.

[0035] Based on the multi-dimensional splitting results, the multi-dimensional feature attributes of each replenishment item are obtained. At the same time, the real-time item information tracking record table of each region is retrieved, and the multi-dimensional feature attributes of each replenishment item are mapped and filled in the real-time item information tracking record table based on the retrieval results.

[0036] Based on the mapping and filling results, the contract management rules for each item in different regions are determined, and the contract management rules are configured as an automatic triggering mechanism.

[0037] The automatic triggering mechanism is linked to the real-time item information tracking record, and the real-time status of items in each area is tracked and managed based on the linkage result.

[0038] Preferably, in an RFID-based smart shelf inventory management method, step 2 involves real-time monitoring of item outbound operations, including:

[0039] Based on sensors, the storage information of items in each area of ​​the smart shelf is obtained in real time, and the storage status of each item on the smart shelf at different times is obtained.

[0040] Repeatedly compare the storage status at adjacent time points, and determine that there is an item outbound operation when there is a change in storage status;

[0041] Based on the judgment results, the storage status change information is parsed to identify the items whose status has changed and to extract the item identifiers of the items whose status has changed.

[0042] The system retrieves the corresponding item information from the backend database based on the item identifier, and dynamically generates an outbound list based on the item status change and the corresponding item information.

[0043] Preferably, in a smart shelf inventory management method based on RFID, step 3 involves tracking the payment status of items based on outbound operations and automatically updating the inventory information of each area on the smart shelf after successful payment, including:

[0044] The outbound items are locked based on the outbound operation, and the sales amount of the outbound items is determined based on the item information of the outbound items.

[0045] The payment management terminal is accessed based on the sales amount, and the payment status and payment amount of the outbound items are determined based on the access results.

[0046] When the payment status of the outbound item is "paid" and the payment amount is consistent with the sales amount, the outbound item payment is determined to be successful, and the outbound authorization is granted based on the determination result.

[0047] Based on the outbound authorization results, the outbound items are reconciled, and the inventory information of each area on the smart shelf is automatically updated based on the reconciliation results.

[0048] Preferably, an RFID-based smart shelf inventory management method determines the payment status and payment amount of outbound items based on access results, including:

[0049] When there are abnormalities in the payment status and payment amount of outbound items, the outbound items are determined to be abnormal outbound items, and an abnormal warning notification is generated based on the determination result;

[0050] Warnings are issued to management terminals based on anomaly alerts.

[0051] This invention provides an RFID-based intelligent shelf inventory management system, comprising:

[0052] The replenishment monitoring module is used to acquire inventory information of each area on the smart shelf based on sensors, and generate a replenishment plan when the inventory is lower than the safety level;

[0053] The inbound and outbound management module is used to identify replenishment items and plan their inbound scheduling based on RFID according to the replenishment plan, and to perform inbound operations on replenishment items based on the identification and inbound scheduling plan. At the same time, it monitors the outbound operations of items in real time.

[0054] The inventory management module is used to track the payment status of items based on outbound operations and automatically update the inventory information of each area on the smart shelf after successful payment.

[0056] By acquiring and analyzing inventory information from various areas of the smart shelves, the system automatically generates replenishment plans when needed, ensuring a continuous supply of goods. Secondly, during replenishment operations, it identifies and plans the inventory inbound process, ensuring accurate placement, efficient warehousing, and maximized space utilization. Simultaneously, it monitors the outbound activity of items on the smart shelves in real time. Finally, when outbound activity is detected, it tracks the payment status to ensure successful settlement before release, preventing theft. Furthermore, it updates inventory information promptly after outbound activity, achieving comprehensive and effective management of goods on the smart shelves. This saves significant manpower and resources while improving overall inventory management efficiency.
