Application of RFID technology in intelligent warehousing in various industries

Intelligent warehousing is currently widely used in various industries, especially in emergency reserves, emergency rescue, disaster preparedness and mitigation, etc. It mainly plays a key role in buffering, adjusting, and balancing, and is the premise and guarantee for emergency rescue and disaster reduction. Design and establish a complete warehousing management process, improve the warehousing turnover rate, give full play to the function of material reserves, ensure that the material reserves are timely and effective in response to public emergencies, maintain normal production order and social stability, and prevent public emergencies from affecting the city. The impact on national economic and social development is minimized.

At present, intelligent warehousing is also applied to various industries around us, especially in emergency reserve, emergency rescue, disaster preparedness and mitigation, etc. It mainly plays a key role in buffering, adjusting, and balancing.

Specifically, smart warehousing is currently facing some problems, mainly in the following aspects:

1. Inaccurate inventory statistics

2. Filling in the order is not standardized

3. Loss of goods during transportation

4. The efficiency of inventorying goods is low

5. High labor cost

system introduction:

RFID is a non-contact automatic identification technology. Its basic principle is to use radio frequency signals and spatial coupling (inductive or electromagnetic coupling) non-contact transmission characteristics to realize automatic identification of identified objects and exchange data. The system adopts B/S+C/S structure and consists of two parts: data traceability platform (B/S) and handheld (PC) client program (C/S). The data traceability platform has functions such as management and enterprise ERP system data docking, client data interface support, and traceability information viewing. The client program is divided into two types according to the software environment: handheld client (winCE system) and PC (window system) client. The handheld client has the functions of receiving, putting on shelves, picking, and inventory, and the PC client has the functions of label initialization and delivery.

System goals:

warehouse space is limited, and one cargo location corresponds to multiple SKUs to improve warehouse utilization.

There is a large amount of periodic picking, and there are many and urgent orders. It is necessary to improve the picking efficiency and optimize the picking path.

Improve the efficiency of receipt and delivery, and the accuracy rate of receipt and delivery is 100%.

Guarantee the accuracy rate of warehouse commodity storage and improve inventory efficiency.

anti-counterfeiting traceability: used for online anti-counterfeiting and commodity flow tracking.

Improve the information management of brand warehouses and optimize the logistics supply chain of finished products.

System functions:

1) RFID tag initialization and supply method

The manufacturer will provide the final RIFD label products after classification printing, initialization, testing, classification and packaging.

After the brand owner initializes the RFID tags according to the production order, they distribute them to the corresponding processing factories.

2) The processing factory checks the standard and packs

After the production is completed and before packing and delivery, the processing factory uses the RFID label inspection machine and RFID scanning packing system provided by Rovinj for RFID label detection. Carry out a single commodity inspection on the product before leaving the factory to minimize the follow-up problems caused by the wrong label or forgetting to hang the label in the processing link.

3) Storage management

When the warehouse receives the goods from the processing plant, it uses the RFID handset to scan and check the goods without opening the box, and uses the warehousing form of the ERP system as the source order to scan the goods quickly and accurately.

4) Operations in the warehouse

Commodity shelving: Computer calculations automatically allocate the storage space, and warehouse personnel follow the instructions to put the goods on the shelves.

After the standard-based put-on-shelf operation, the system automatically finds out the location where the item is Stored, and through computer calculations, guides the picking path according to the location where the item is stored, optimizes the picking path, and uses the least amount of time for picking goods operation. Simple and intuitive picking guidance, even new employees who have just entered the job can easily complete the work.

5) Outbound management

Use the RFID desktop all-in-one machine, use the delivery note of the ERP system as the source order, and scan the delivery quickly and accurately. If it is found that it does not match the SKU or quantity of the delivery note, the system will give an abnormal prompt, and it can only be completed after the abnormal information is excluded. The operation.

6) Warehouse inventory

Use the RFID handheld terminal to operate. The inventory system supports functions such as blind order, order by inventory, order by warehouse, and goods search.

Use RFID handheld devices when performing partial or full inventory of inventory in the distribution center. Operators use handheld devices to scan the shelves in the area that need to be counted one by one, and the detailed varieties and quantities of the batch of goods are counted in real time. After the actual scanning results are combined and counted, they are uploaded to the traceability platform, and the inventory data is checked by the traceability platform.

When it is necessary to find a specified type of goods, but the specific location of the goods is not known, it can be done by using the RFID handset.

Enter the style and color code of the goods you want to find on the handheld device and use the handheld device to perform overlay scanning.

When approaching the goods to be searched, the handheld machine will emit a warning sound, and the closer the goods are, the louder the sound will be, so as to help personnel find the goods accurately.

RFID data traceability platform

The RFID data traceability platform is aimed at modules with data display for all the above modules, and also includes: user management, basic data management, anti-counterfeiting traceability and other modules.

Data docking platform

The project uses the API interface for data exchange, and the required documents are pulled from the ERP as the source documents of the system. If necessary, the data in this system can also be backfilled to the ERP system.

In the entire RFID warehouse management operation, the characteristics of long-distance identification, large-scale reading and accuracy of RFID technology are applied to the process of warehouse management, such as warehouse entry, warehouse operations, warehouse departure, inventory, and sorting. Utilize the characteristics of RFID to change the traditional inventory management method, intelligently collect data through analysis and processing, obtain intelligent insights to improve business leanness, maximize the investment value of the enterprise, save human resources, and bring a brand-new to the enterprise warehouse management.
