[0018] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. 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 should fall within the scope of protection of the present invention.

[0019] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate for the embodiments of the invention described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0020] It should be noted that, unless otherwise specified, the embodiments and features described in the present invention can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0021] According to embodiments of the present invention, a method for intelligent end-of-linen distribution is provided, such as... Figure 1 As shown, steps 101 to 103 are included below:

[0022] Step 101: In response to receiving a request from the terminal to deliver goods to any hotel, retrieve the delivery order corresponding to that hotel, wherein the delivery order is generated based on a soiled goods slip generated by scanning soiled linens with an RFID scanning terminal.

[0023] In this step, the user uses a handheld RFID scanning device (the RFID scanning terminal is deployed at the factory's shipping end and consists of a high-frequency RFID reader and an industrial tablet) to select the floor where soiled linens need to be processed via an app installed on the device. The system records the hotel, category, specifications, grade, and quantity information of the soiled linens for that floor (e.g., Hotel A, sheets, 1.8M, premium, 25 sheets). After the user has scanned all the soiled linens on that floor, they submit the scan, and the system generates a soiled linen shipping document for that floor. Simultaneously, based on this document, it generates clean linen delivery data for that floor of the hotel, with the clean linen delivery quantity matching the soiled linen delivery quantity. The driver then repeats the same process for other floors until all floors are processed. A total soiled linen shipping document for the current hotel is generated, recording the soiled linen delivery quantity for each floor. The soiled linen delivery quantity for each floor matches the clean linen delivery quantity for each floor in the T+1 order for that hotel.

[0024] Step 102: Obtain the information of the linens to be picked up by the RFID scanning terminal, and match the information of the linens to be picked up with the picking order.

[0025] Step 103: Update the quantity of goods to be allocated based on the matching results.

[0026] In this embodiment, during the order fulfillment process, when an operator places a piece of linen to be fulfilled onto the RFID desktop scanning tablet, the screen displays the following information about the linen: hotel, category, specifications, grade, number of washes, and chip code (e.g., AA Hotel, sheet, 1.8M, premium, 35 washes, 30000XXXXXXX). Simultaneously, the system retrieves AA Hotel's daily delivery orders. Each floor requiring fulfillment in the order is displayed via a separate chip page. The system defaults to fulfilling orders from lower to higher floors. If the current linen is the first item the hotel needs to fulfill, it will be assigned to the floor with the lowest chip code. Although each floor may have a different quantity of linen to fulfill, textiles can circulate between different floors; there is no restriction that a particular textile must always be delivered to the same floor. Once a certain type of textile has been distributed to the floor with the lowest number, if this type of textile comes off the production line again, it will be distributed to the next floor in sequence. Once all the textiles on the floor with the lowest number have been distributed, the distribution will proceed sequentially floor by floor until all floors have been distributed.

[0027] As an optional implementation of this embodiment, when the RFID scanning terminal scans soiled linens to generate a soiled linen receipt, it obtains linen attribute information from the chip of the soiled linen, wherein the linen attribute information includes the name of the hotel to which the linen belongs, the type of linen, and the floor where it is located; it counts the number of linens on different floors to obtain a receipt for the number of different soiled linens on different floors corresponding to any given hotel.

[0028] This implementation method overcomes the shortcomings of floor-level linen management, which cannot achieve detailed delivery and statistics.

[0029] As an optional implementation of this embodiment, obtaining the linen information to be picked up scanned by the RFID scanning terminal, and matching the linen information to be picked up with the picking order includes: obtaining the linen information to be picked up scanned by the RFID scanning terminal, wherein the linen information to be picked up includes hotel name information, floor information, and category information in the chip of the currently scanned linen; determining whether the hotel name information matches the hotel information indicated in the picking order, and whether the category information matches the category indicated in the picking order.

[0030] As an optional implementation of this embodiment, updating the quantity of goods to be picked based on the matching result includes: if a match is found, then the quantity of goods to be picked is counted; if a match is not found, then the information of the linens to be picked currently being scanned is marked as abnormal.

[0031] In the above optional implementation, orders from multiple hotels are processed daily, with each order listing the required types and quantities of linens.

[0032] For example: - Orders from the Beijing Marriott Hotel:

[0033] King bed sheets: 100 pieces

[0034] Queen duvet covers: 80 pieces

[0035] Towels: 60 pieces.

[0036] When an employee scans linens, the system automatically determines whether the linen belongs to the current order and whether it is the correct type. If it does, it is counted in the order quantity; otherwise, it is marked as abnormal (wrong order, wrong type, etc.).

[0037] Example logic: if the hotel to which the linens belong is equal to the hotel in the current order and the linen category is in the order: increment the quantity of the corresponding category by 1; else: mark as an exception (e.g., wrong hotel, wrong category).

[0038] The above-mentioned optional implementation methods achieve intelligent order fulfillment through automatic matching. As an optional implementation method in this embodiment, the method further includes: vectorizing the information of linens in the order fulfillment and the information of all linens to be fulfilled scanned by the order fulfillment RFID scanning terminal; and performing statistics on the vectorized vectors through a preset statistical model to determine in real time the missing categories and corresponding quantities of linens compared with the information of linens in the order fulfillment.

[0039] In this optional implementation, in order to count the quantity of goods to be delivered and the shortage, the system represents the order and the actual scanning results as vectors: order request vector P = [100, 80, 60] (bed sheets, duvet covers, towels); actual scanning result A = [90, 80, 55]; the system calculates the shortage: Δ = PA = [10, 0, 5], which means that there is a shortage of 10 bed sheets and 5 towels.

[0040] This implementation overcomes the shortcomings of untimely identification and feedback of abnormal situations, which affect the overall production and service quality.

[0041] As an optional implementation of this embodiment, the method further includes: determining a matrix based on the category information and floor information of linens in the order and the category and floor of the linens in the current linen information scanned by the RFID scanning terminal, so as to perform order fulfillment through the matrix.

[0042] If the hotel requires delivery by floor, the system will convert the vector into a matrix representation and count the items floor by floor:

[0043] The system performs statistics and matching for each floor and each type of linen, ensuring that the distribution is accurate down to the floor level.

[0044] For example, each order is represented as a vector P = {p1, p2, ..., pn} according to the number of types. The actual scan input is given as A = {a1, a2, ..., an}.

[0045] During scanning:

[0046] If b.hotel == order.hotel and b.spec in P:

[0047] A[b.spec]+=1

[0048] else:

[0049] Marking anomalies

[0050] Statistical gap: Δ = PA.

[0051] For delivery involving floors: vector P,A is promoted to matrix P[i][j].

[0052] This embodiment differs from static sorting in related technologies by implementing dynamic correlation characteristics, solving the problem of lag in manual statistics through a data processing mechanism of real-time updates and gap calculation, and improving system robustness through a closed-loop control logic of "anomaly identification-alarm-reprocessing".

[0053] This embodiment overcomes the shortcomings of existing technologies, such as the susceptibility of manual sorting to linen mismatches (e.g., wrong hotel, incorrect specifications), and the inability to identify linen information when RFID chips fall off, resulting in data loss. Traditional systems only support full order fulfillment for hotels and cannot meet the needs of refined distribution by floor, leading to chaotic linen circulation at the floor level. Furthermore, the reliance on manual detection for anomalies such as mismatches and missing chips results in feedback delays that affect the timeliness of error correction and increase the risk of misdelivery.

[0054] It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and although a logical order is shown in the flowchart, in some cases the steps shown or described may be executed in a different order than that shown here.
