Specifically, the key cargo features need to be encoded for storage and transmission in the NFC tag, each key cargo feature may be encoded by an encoding format (such as UTF-8 encoding or binary format) to generate a key cargo feature encoding, for example, the cargo name is "ABC commodity", the cargo number is "12345", the production date is "2023-01-01", the validity period is "365 days", the weight is "1.5kg", and the size is "20cm x 10cm x 5cm", and then binary encoding is performed on each feature to obtain a binary encoding corresponding to each key cargo feature, that is, the cargo name encoding: [ field 1 after encoding ], goods number encoding: [ field 2 after encoding ], date of manufacture code: [ encoded field 3], validity period encoding: [ encoded field 4], weight encoding: [ field 5 after encoding ], size encoding: the coded field 6 is used for further filling the coded characteristic data into the corresponding field according to the tag data structure and the key cargo characteristic code, generating an NFC tag of the target cargo, writing the generated tag data into an NFC tag chip, ensuring that the tag data is matched with the generated tag data structure, carrying out proper verification and authentication on the generated NFC tag, and carrying out test and authentication on the NFC tag, wherein the reading function of the NFC reading device is used for verifying that the tag correctly analyzes and acquires the stored cargo characteristic information.

Further, based on the NFC label corresponding to each target cargo, the target cargo can be subjected to warehousing or ex-warehouse operation, different types of warehoused cargoes can be rapidly identified and distinguished through NFC label scanning and cargo classification screening, the time and cost for manual identification and classification are reduced, the warehousing efficiency is improved, the error rate is reduced, and the follow-up warehouse storage, allocation and ex-warehouse operation are facilitated.

In the embodiment of the invention, the range of the warehouse-in goods refers to a specific area where the warehouse-in goods are stored in a warehouse, usually a specific goods shelf, a storage cabinet or a specific area in the warehouse, and in the range, all the warehouse-in goods should be correctly classified, marked and stored so as to ensure the high efficiency and the accuracy of warehouse management; for different types of cargoes, the range of the cargoes in storage may be different, so before storage, classification and screening are needed according to the attribute of the cargoes, and the range of the corresponding cargoes in storage is determined.

In the embodiment of the present invention, when the nfc tag generation module 101 performs initial cargo category screening on the warehouse-in cargo according to a preset warehouse-in request of the warehouse-in cargo and the nfc tag, the method is specifically used for:

In detail, according to the nfc labels of all target goods in the goods warehouse, the nfc labels of the warehouse-in goods corresponding to the warehouse-in request can be determined, each warehouse-in goods has an independent unique nfc label, each goods category has a corresponding warehouse area, the goods category area stored in each category goods in the goods warehouse can be determined based on the goods areas corresponding to different goods categories in the goods warehouse history data, and the goods category label corresponding to each goods category area is detected, and the goods category label is used for identifying the goods category to which the goods category area belongs, such as food, electronic products and the like.

Specifically, the stock-in goods nfc label is screened according to the goods category label, so that a goods category area corresponding to the stock-in goods can be obtained, and then the stock-in goods category area is used as a stock-in goods range, if the goods category label is food, and the goods category in the stock-in goods nfc label is food, the stock-in goods is marked in the stock-in area of which the goods category label is food, and the stock-in area corresponding to the food label is the stock-in goods range of the stock-in goods, so that a warehouse manager can be helped to quickly find the stock-in goods, and place the stock-in goods in a proper position, so that the goods can be managed and tracked better.

Further, for the warehouse-in goods only matched to the warehouse-in goods range, the warehouse-in position is not determined, and in order to accurately locate the warehouse-in position of the warehouse-in goods, the accurate warehouse-in position of each goods needs to be determined based on the signal of the nfc label of the goods, so that the warehouse-in efficiency of the goods is improved.

In detail, the signal receiving intensity refers to a signal sent by a warehouse-in area with a blank area in the warehouse-in cargo range, and reflects the sensitivity of the tag reader to the signal in the warehouse-in blank area. Stronger received signals generally means that the tag reader is closer to the signal source or that the propagation conditions of the signal are better; a tag reader is generally a device for receiving a wireless signal from a load, which may measure the strength of the signal, and which receives the signal from an empty area of the load in storage, typically by RFID technology or other wireless communication technology, and which may measure the strength of the received signal and represent it as a value which may reflect the relative strength of the signal, typically in dBm (decibel milliwatts), a higher value representing the strength of the received signal and a lower value representing the strength of the received signal, thereby determining the signal transmission strength of the empty area of the load in storage; in addition, the signal transmission intensity is the intensity of a signal transmitted by the tag reader, and is used for communicating with the tag in the range of the warehouse-in goods, and in the warehouse-in empty region, the tag receiver transmits a test signal, and the power of the test signal transmitted by the tag receiver, namely, the power is the signal transmission intensity, can be measured through a built-in power measurement function or external measurement equipment.

Specifically, the signal strength loss algorithm can calculate the signal distance of the warehouse-in position between the tag reader and the warehouse-in empty area at different positions, wherein the gain compensation factor G is a parameter for considering the gain of the receiving or transmitting device, in the actual situation, the gain (or loss) of the hardware device of the tag reader may affect the strength of the signal, in order to calculate the signal receiving strength more accurately, the gain compensation factor is introduced, and the gain compensation factor is usually a constant, and can be adjusted according to the characteristics of the hardware device, so as to reflect the actual situation more accurately.

Further, through the calculated signal transmission distance, accurate estimation of the actual position of the warehouse-in goods can be obtained, the goods can be accurately placed at the designated position, misplacement or confusion is avoided, an automatic warehouse-in process can be realized by utilizing a warehouse-in position signal distance positioning technology, behaviors can be automatically adjusted according to the change of the signal distance, and a high-efficiency warehouse-in process is realized.

In the embodiment of the present invention, when the cargo warehousing information generating module 102 locates the actual warehousing location of the warehoused cargo according to the warehousing location signal distance, the method is specifically used for:

X＝(A^TA)^-1A^Tb+e

In detail, the layout of the tag readers can be determined in the warehouse-in cargo range, if three tag readers are configured in the warehouse-in cargo range A area, and nfc tags of different types are configured in each cargo area of the warehouse-in cargo range A area, the signal receiving position of each tag reader can be obtained based on the layout of the tag readers, simultaneous equations are carried out on the signal receiving positions of different tag readers and the warehouse-in position signal distance, and a position matrix and a signal position distance key matrix can be obtained.

Specifically, when there are three tag readers, the signal receiving position of each tag reader is (x 1, y 1), (x 2, y 2), (x 3, y 3), the coordinates of the warehouse-in empty area corresponding to the warehouse-in goods are set to be (x ₀,y₀), and the warehouse-in position signal distances between the three tag readers and the warehouse-in empty area are d ₁,d₂,d₃ respectively, the first equation set can be obtainedSubtracting the last equation from each equation in the first equation set to obtain a second equation set, wherein the second equation set isLet the second equation set be atx=b, then/> X= [ X ₀y₀ ], i.e. x= (a ^TA)^-1A^T b, where a is the position matrix, b is the signal position distance correlation matrix, the position error matrix e is composed of e _x and e _y, then/>E= [ e _x e_y ], so that the actual warehousing position of the warehoused goods can be obtained.

Further, when the warehouse-in goods are positioned to the actual warehouse-in position, the warehouse-in information of the goods warehouse can be updated in real time so as to ensure the accuracy and timeliness of inventory management, the actual warehouse-in position is associated with the warehouse-in information of the corresponding goods, the actual warehouse-in position information is associated with the identification, quantity, attribute and other information of the goods, once the actual warehouse-in position is determined and associated with the goods information, the warehouse-in information of the goods can be updated in real time, the warehouse-in information reflects the actual situation and can be used for subsequent inventory management, logistics operation, inquiry and the like, the actual position of each goods can be accurately known, the efficiency and the accuracy of inventory management are improved, the situation that the goods are misplaced can be avoided, the goods can be quickly searched, the inventory can be timely supplemented, and the like, and warehouse operation and logistics business are optimized, wherein the warehouse-in information comprises the position, quantity, warehouse-in time, the name, the specification, the model, the batch number and the warehouse-in single number of the goods.

In detail, the value and timeliness of each shipment are evaluated in the range of the shipment, and the value coefficient of each shipment is determined according to the value standard of sales value, market demand degree and emergency degree of the shipment, and can be obtained by a linear functionCalculating a value coefficient, wherein a _m is a weight coefficient of an mth value standard, x _m is a value score of the mth value standard, M is a standard attribute number of the value standard, for example, when the sales value is greater than or equal to a preset sales price, the sales value is given to 1, and when the sales value is less than the preset sales price, the sales value can be given to 0.5; for the market demand level, a linear function g (h) =wh+b of the market demand can be constructed according to the cargo demand, where g (x) is a value score of the market demand level, w is a linear parameter, h is the number of delivered cargo, and b is an intercept, and then the value score of the market demand level is determined based on the number of delivered cargo at the moment, so that the value coefficient of the value standard of the delivered cargo can be calculated.

Specifically, the time standard is a standard for measuring the time sensitivity of the goods, and can be an expiration date, a stock period, order urgency and the like of the goods, so as to evaluate the delivered goods and assign corresponding time coefficients, and the goods can also be processed through a linear functionCalculating a value coefficient, wherein c _n is a weight coefficient of an nth time standard, y _n is a time fraction of the nth time standard, N is a standard attribute number of the time standard, and if the time difference between the deadline delivery date and the current date of the goods is less than or equal to a preset threshold value, the time coefficient is given to 1; otherwise, gradually reducing the time coefficient according to the size of the time difference; if the stock period of the goods is smaller than or equal to a preset threshold value, the time coefficient is given to 1; otherwise, gradually reducing the time coefficient according to the size of the stock period; the method comprises the steps of evaluating and assigning corresponding time coefficients according to the urgency level index of an order, mapping the urgency level index to the time coefficients, if the urgency level is higher, assigning the time coefficients to 1, and when the urgency time is lower, gradually reducing the time coefficients, so that the time coefficients of the time standard of the delivered goods can be calculated, wherein the weight coefficients of the value standard and the weight coefficients of the time standard can be assigned with different weight values through subjective judgment.

Further, in the delivery priority algorithm, when k=1, it indicates that delivery of only one delivery category is needed, and at this time, delivery of delivery is not compared with delivery of other delivery, the delivery priority of delivery is configured as 1, and delivery of delivery is only needed, and when k >1, it indicates that delivery of delivery categories is not only one, the order of delivery of the goods is determined according to the priorities among the goods categories, and the larger the value coefficient is compared with the time coefficient, the larger the priority of the goods is, so that the goods with higher priority can be delivered first, the situation that the goods with lower priority are misplaced or missed is avoided, and the delivery accuracy is improved.

Further, only the priorities are configured for different types of cargos in the process of delivering the cargos, and when delivering the cargos of the same type, information conflict and noise label collision phenomenon among the cargos of different delivery can occur, so that the label collision phenomenon is analyzed to ensure that the positions of the delivered cargos can be accurately determined, the condition of delivering the wrong cargos is avoided, the error rate is reduced, and the delivery accuracy is improved.

The cargo shipment information generating module 104 is configured to locate an actual shipment position of the shipment cargo by using a preset tag collision algorithm and the shipment cargo priority, and update shipment information of cargo warehouse in real time according to the actual shipment position.

Specifically, all the outgoing cargoes in the outgoing cargoes range are provided with nfc labels, the nfc labels of the outgoing cargoes are compared with the nfc label instructions on the goods shelves one by one, matched outgoing cargoes are found, the outgoing collision position of the outgoing cargoes is determined according to the outgoing cargoes, the binary coded data coded according to the nfc table labels are compared with the binary codes in the nfc labels in the outgoing cargoes range one by one, if the nfc labels of the outgoing cargoes are required to be A, B, C, the labels corresponding to the nfc label instructions in the outgoing cargoes range are A, B, C, D, E, the matched labels are A, B, C, the label comparison position is A, B, C label corresponding position serial number, and then the label comparison position is taken as the outgoing collision position of the outgoing cargoes, and the outgoing collision position is the cargo storage position coordinate responded by the labels at the same moment.

Further, when the number of the collision labels is only one, the number of the collision labels indicates that the collision positions of the delivery are also only one, and the target delivery goods can be determined, so that the actual delivery position of the target delivery goods is determined according to the delivery collision positions of the target delivery goods; when the number of the collision labels is larger than one, the collision positions of the delivery are represented to be more than one, the delivery sequence of the delivery is determined according to time response time in the delivery types, the delivery sequence with fast response time is more forward, the delivery sequence of each delivery can be determined, and the delivery collision position corresponding to each delivery is further taken as the actual delivery position of the delivery.

For example, when the number of collision labels is two, the corresponding shipment of the collision labels is a and B, the shipment collision positions corresponding to the shipment a and B are X _A,X_B, and when the shipment a and B are not of the same shipment category, when the priority of the shipment a is greater than that of the shipment B, the shipment a is taken as the target shipment, and the shipment collision position X _A is taken as the actual shipment position at the moment; if the shipment a, B is of the same shipment category, when the response time of the shipment a is earlier than the response time of the shipment B, the shipment a is taken as the target shipment, and the shipment collision position X _A is taken as the actual shipment position at that time.

In the embodiment of the invention, once the actual delivery position of the goods is monitored, the information is immediately fed back to the warehouse management system, the delivery state of the goods can be set to be delivered according to the unique identifier (such as RFID tag) of the goods, and after confirming that the goods are delivered, the system should update the inventory information in the warehouse management system.
