1. Program overview
This program is tailor-made for customers by Shanghai Fuen by analyzing the needs of the company. It integrates RFID technology, network technology, computer technology, database technology and wireless communication technology. Combining the actual needs of the company and Fuen’s rich experience and unique technology, we propose the following formal plan for the RFID logistics retail management system.
noun:
1. Clothing label: refers to the RFID label pasted, implanted or hung on a single piece of clothing, with a unique unchangeable ID number, which can be read remotely. There are many manifestations: plastic tag, paper tag, self-adhesive labeling (sticking on the tag), flexible description label, etc.
2. Box label: refers to the one affixed to the designated position of the boxRFIDThe label, with visual information on the surface, is added by the labeler.
3. Position label: refers to the RFID tag fixed at the designated position on the goods position, with visual information on the surface, which will be added by the labeler.
2. Program objectives
1. In the headquarters warehouse, the goods can be quickly put in and out of the warehouse in batches to shorten the overall supply cycle
2. Realize real-time statistics of purchase, sales and inventory and fast replenishment in stores, so as to achieve the purpose of efficient operation, promotion of sales, and statistics of consumption habits.
3. Channel logistics information can be tracked in channel management, to a certain extent, to prevent cross-country goods, combat illegal online sales, and implement channel management policies.
Three, system architecture
The overall workflow of the system is as follows:
Fourth, the program operation process
1. RFID clothing tag information writing
Write the information of the new tag label
If the RFID clothing label in the form of a PVC card tag is used, the RFID inlay is directly laminated on the middle layer of the tag to form a whole. This kind of label can be repeatedly erased and written, recycled and reused many times, so as to greatly reduce the investment cost of the enterprise.
This type of tag tag can use a special RFID automatic card issuance device to write the tag identification information, as shown in the figure below. At this time, usually one side of the hard tag is only printed with the brand image, and the other side is left blank, and then one print is printed with The self-adhesive instructions for the color code and barcode information are attached to the back of the tag (the self-adhesive label uses removable glue, which can be easily removed during recycling and reuse without leaving residual glue). The automatic card issuing device is based on the first reading Take the barcode information and write the unique code corresponding to the barcode into each tag chip.
Clothing label—PVC hard tag, automatic initialization device
The general operation process of the initialization of the rigid tag label is as follows:
1) The tag management department retrieves all the bar code information of this order from the system according to the production order, and prints it into a self-adhesive description label (ordinary self-adhesive label paper uses a self-adhesive material with removable glue. This glue is in PVC The surface can be pasted repeatedly without leaving any residual glue, and it is convenient to clean up when it is recycled and reused in the future to keep the surface of the tag tidy);
2) Paste the sticker on the back of the RFID tag;
3) Use a customized automatic card issuing device to write cards in batches; the card issuing device will first read the barcode information on each tag, and then generate the unique code of the tag and write it into the RFID chip, and at the same time verify the quality of the tag label ( Check the correctness of the information written in the tag and the performance of the tag by reading multiple times);
4) Pack the tags of different SKUs and pack them separately. The SKU and color code information are clearly marked on the packaging box, and the tags of different SKUs must be avoided to be mixed together.
5) Distribute the initialized labels to various processing plants in accordance with the production order.
Since this system only involves the application of logistics and other links, it does not involve the functional requirements of anti-crossing goods, so it only needs to use the EPC code writing and TID reading of the RFID tag, and the clothing needs to be recalled from the ERP system when the tag is initialized. Code, the unique code of the generated tag is written into the EPC storage area, and the TID number of the tag is used as a unique judgment to strengthen the reliability and robustness of the system.
It only takes 3 seconds for the RFID automatic card issuance device to read a tag from barcode reading to write to verify the performance of the tag. One card issuer can write 12,000 tags in 10 hours a day, and two card issuers can complete the writing. 24,000 tags are written.
Write the information of the recycling label
For the tag labels that are recycled and reused, a pretreatment process is required. This includes:
1) Tag data clearing: This can be done in two steps: first, when selling clothing, the tag cut from the clothing immediately leans against another card reader under the sales counter (this card reader The device is controlled by a program that specifically rewrites the label to a series of meaningless serial codes to rewrite the original barcode information in the tag chip into a serial code) to complete the removal of the tag data; the second is that the sales terminal does not handle it, and the front is returned After arriving at the headquarters, the headquarters uniformly uses the automatic card issuing device to sequentially write the serial code into each tag to complete the removal of the original barcode data.
2) Surface cleaning: wipe off the sticker on the reverse side of the tag with alcohol or Polaroid and other cleaning agents (the label is removable glue, it can be removed by gently erasing or tearing it off, leaving no residual glue), Then screen out the tags with good surface and no obvious scratches and creases for secondary use.
3) In accordance with the five-step process of writing new tags as described above, rewrite the new barcode information on the recycled labels, pack them and send them to the factory.
2. Hang tags
When the factory dispatches orders, according to the different clothes of each color code on the order, the corresponding number of RFID brand labels corresponding to the SKU are used as an auxiliary material along with the traditional tag, and the production raw materials of the order are placed together with the production line or production team for management. When the finished garment is off the line, take out the RFID tag and traditional paper tag from the corresponding label package according to the SKU of the produced garment and hang it on the garment together. Only take one SKU label at a time and avoid mixing different styles to avoid confusion.
After the clothing is off the assembly line, it is packed according to the principle of packing one SKU as far as possible in the same box, and then the color code information and quantity are clearly marked on the packing label on the surface of the box.
The factory sends the invoice of the wholesale goods to the headquarters of the brand owner through the network platform to make an advance notice of delivery so that the warehouse can be checked after the arrival of the goods in the headquarters.
2.1 Inbound quality inspection
After the finished garment is shipped to the warehouse of the brand’s headquarters, it needs to undergo quality inspection first. The first process of quality inspection is to use an RFID desktop reader or a special inspection and packing workbench (including a desktop RFID reader and a PC, and an automatic conveyor belt) to verify the attachments one by one Whether the RFID tag label information of the RFID tag is consistent with the label, the washing label, and the goods themselves or whether the label is missing, if not, enter the temporary storage area and wait for correction before entering the warehouse.
2.2 Check-in revenue library
Utilizing the existing receiving and distributing channels and installing an imported 4-channel high-performance card reader produced by Impinj, it can identify 120 tags at the same time, ensuring that the single-box recognition rate of clothes and trousers is 99%.
After the goods arrive, the operator calls out the arrival notice waiting to be received, and after verification and confirmation, drives the RFID receiving scanning channel to start scanning the goods box by box. The operator moves a whole box of goods to the conveyor belt of the scanning channel, and the channel will automatically transmit and scan the details of the goods in the box through the RFID reader. During the cargo scanning process, the program interface will display information such as the manufacturer, order number, product content, planned arrival quantity, actual arrival quantity, and arrival box number of the batch of goods, and display the difference information.
If there is a difference between the scanning result and the packaged approved quantity and the packaged goods, enter the “reverse inspection processing area” and wait for manual scanning and inspection.
After the receiving scanning operation is completed, the program will upload the scanning results and record the corresponding attributes of each piece of goods in the database, including receiving time, receiving location, operator number, etc. And record the corresponding attributes of the order, including the order receipt quantity, receipt time, receipt difference, etc.
It only takes 12-15 seconds to scan a box of clothes in the RFID receiving and delivery channel. According to a box of 30-40 pieces, it can complete 72,000-96,000 pieces of clothing in a day’s work for 10 hours.

2.3 Picking and distribution
Picking and distributing goods is a tedious task in the headquarters warehouse, and it is often prone to picking errors, which increases the workload of counter-checking when leaving the warehouse. This system proposes a picking and distributing process based on cargo location and handheld machine to improve picking accuracy and work efficiency.
The distribution operation process is as follows:
(1) Establish the SKU location definition function on the existing system, you can easily query the location of each SKU;
(2) After creating a new delivery order in the system, you can print out the delivery order containing the location information, and sort it according to the location number, so that the delivery staff can make a reasonable pick-up route.
On this basis, we propose a more advanced distribution method-dynamic distribution through the handheld, as shown in Figure 2:
(1) After the delivery staff creates a new delivery order in the ERP system, they can directly download the delivery list to the handheld (no need to print the delivery list, save paper, and be green).
(2) The handheld device dynamically displays all the positions of this distribution list and the number of parts waiting and the number of parts in each position, and sorts them according to the optimized pick-up route;
(3) The stocking staff can scan the tag barcode and RFID information through the handheld machine for automatic comparison, which greatly improves the accuracy of the distribution.
(4) Through the handheld, the system will automatically remind the stockist how many SKUs have not completed the distribution (instead of manually marking on the paper receipt).
This system supports multi-order combined picking to reduce the time between different cargo positions and improve overall efficiency.
2.4 Sealing the box and leaving the warehouse
According to the order, put the same SKU clothing in the same box as much as possible, and then print the packing list, put the packing single in the box, and paste the other one to the designated position of the box, and then seal the box.
The first step is to place the packaging box to be sealed on the RFID scanning channel to scan the whole box, and check whether the product quantity, model number, color, size, etc. in the box are correct. After passing the inspection, proceed to the next step; if there are discrepancies, the packaging box will enter the process of “return to inspection box”.
The second step is to print out the RFID printer of the packing list of the package that passed the inspection. The printer will write the statistical information of this box of goods into the label chip while printing the text identification information on the label surface. Attach the packing label to the designated location of the packing box, then seal the packing box and ship it to various agents or flagship stores.
When the agent accepts the goods, he only needs to read the number of SKUs stored in the chip of the packing label and the number of pieces corresponding to each SKU, and then the detailed information of the goods can be obtained. The goods can be checked and accepted by comparing with the delivery note. .
2.5 Store sales management
Store management based on RFID technology includes three parts:
1. Fast settlement of clothing sales, linking the record and update of the invoicing system.
After the customer selects the clothing to be purchased, they go to the front desk for settlement. The cashier stacks the clothing on the RFID scanning platform. The computer displays a detailed list of the purchased goods and automatically calculates the total amount. At the same time, the store’s inventory is reduced.
All sales data is automatically updated to the back-end system in real time through the invoicing system. The headquarters can easily understand the real-time sales and inventory status of each store, and timely and targeted replenishment.
After the cashier completes the checkout, cut off the RFID tags on the clothes one by one, and lean against the RFID card writer hanging on the side of the cashier table (initialize the tags), such as putting them into the tag recycling box at the bottom of the table for Follow-up reuse.
2. Store multimedia display and promotion, that is, use a multimedia advertising terminal with a built-in RFID reader to identify current clothing information, and display related clothing promotion information and inventory information on the terminal to guide consumers to correct consumption and stimulate consumer desire.
3. RFID-based membership management
When consumers buy any piece of Yanhuang brand clothing, there is an RFID tag, which can be used as a membership card at the same time. After the consumer makes the payment, the clerk takes off a tag in the clothing purchased and senses it on the card reader, completes the reading of the member ID, and then enters various basic information of the member, such as name, gender, age, preferences, Work type, etc., and then the card reader will automatically write the member’s name into the tag chip; in the future, every time the consumer shows this tag, he can immediately call up the member’s basic information, and get corresponding promotional discounts during consumption Or accumulated points, and can be classified and automatically upgraded according to the accumulated consumption amount of members.
2.6 Store inventory count
For stores, RFID handheld terminals or POS tablet readers can be used for warehouse inventory. In the inventory, the method of gradual partial inventory for a certain part of the shelf or a certain category or a certain period of time can be used to carry out the inventory, and the warehouse can also be inventoryed when it is free.
For the goods on the shelf, the RFID handheld terminal can be used to walk slowly along the display shelf to ensure that every piece is read. Automatic counting and statistics can be realized, and the inventory data of the original system can be compared to show the difference. At the end of the inventory, the handheld terminal can also perform automatic analysis based on the read labels, and then know the actual quantity of a certain style, a certain color, and a certain model of clothing, so as to ensure the balance of inventory, and timely replenishment, avoiding clothing stores The phenomenon that a certain clothing is out of stock or broken codes can ensure the normal needs of customers.
