Project Background
The application of RFID technology in enterprises has been paid more and more attention. Leaders gradually realize that through RFID technology, can control the supply chain and improve its effectiveness. What’s more, reduce the loss of goods in stock.
The effectiveness of the RFID technology application for inventory management can be 2 points:
1, Fast, fast logistics efficiency, delivery goods, improve logistics operation;
2, Accurate data collection in all aspects of logistics management.
In this article, we will introduce the RFID technology application in warehouse management.
This scheme uses RFID to track forklift, container, and Pallet. And integrates advanced RFID data collection.
In this way, we can improve the efficiency of logistics management and reduce cost.
Introduction of RFID technology
(Radio Frequency Identification, short for RFID) , commonly known as RFID tags, are widely used in asset, personnel, supply chain, and appliance management fields.
Radio Frequency Identification (RFID) is a non-contact automatic identification technology. UHF RFID technology can be long-distance identification of high-speed moving objects and can identify multiple tags at the same time, easy to operate.
The basic RFID application system consists of three parts:
RFID Tag
The coupling component and chip, each tag has a unique number, attached to the Object identification object.
RFID Reader
A device for reading (and sometimes writing) tag information that can be designed to be handheld or stationary.
Software
Acts as an intermediary between RFID tags and application systems, It’s software that streams data in and out of applications and readers.
Radio Frequency Identification (RFID) is considered as one of the most promising information technologies in the 21st century. RFID technology has been applied in a wide range of fields, a high degree of automation, and gradually internationalization and popularization.
Such as personnel management, vehicle management, asset management, production process management, logistics management, cargo tracking management.
The core of the technology is to make people, vehicle, or goods can be recognized by the system. Through the management of the target and the related information, to achieve efficient and scientific management purposes.
SYSTEM SCHEME
In the application of RFID technology for storage management, we need to solve two problems. One is standardizing the storage management process, the second is improving efficiency.
Specifically as following:
Warehouse Management With RFID Tags to identify the Pallet, forklift and container;
When receiving the goods, should compare the information on the pallet and the loaded goods.
Through intelligent RFID handheld reader, collect the data of receiving and delivery.
Through the RFID Identification Channel Terminal System, to achieve count in and out of storage, verification, and inventory automatic update.
RFID Tags for management main in three types:
RFID asset management tags for a pallet, RFID tags for a container, RFID anti-metal tags for the forklift.
Pallet RFID Tag
There are many different types of RFID tags for a pallet, mainly is made of plastic material, also some prefer to RFID paper sticker.
Printing methods, laser printing bar code on the surface of the RFID asset tag or encoding in the IC. For RFID paper sticker, can use thermal printing.
Container RFID Tags normally use RFID seal or RFID anti-metal tags.
Forklift truck tags are mounted on the forklift truck at a specific location and require a metal resistant tag. Fixed installation, a label can be fixed and installed directly or 3m back glue pasted on the forklift.
In storage
Receiving the goods and checking with the data file of the RFID tag on the truck. Then confirm and recording in the system.
After receiving the goods need put on the pallet. Take out a pallet at random, then encode related logistic number in the RFID tag on the pallet. Out of question, the function of those numbers is customized by software. Just scan the tag, you can know every detail about the items on this pallet. No need to open every carton to check them out.
Warehousing confirm
When transferring those pallets into the warehouse, the terminal on the forklift can read the tag on the pallet, through WIFI to transfer the data file to the system. At the same time, another fixed RFID reader installed at the gate. When pallets pass through, double-checking the information is correct or not comparing with the RFID reader on the forklift. In this way, avoiding misreading.
Ex-warehouse
After pick out those items needs to send out, the warehouse keeper will use the handheld RFID reader to check the information on the pallet. Send the details to the system, mark it EX-warehouse.
When forklift takes the pallet out of the warehouse, the fixed RFID reader at the side of the gate recognizes RFID tags on the pallet. At the same time check it and send the data to the system. If there is no problem, means Ex-warehouse confirmation.
Containing
Before sending the goods into the container, the reader on the forklift need get the data of the RFID tag on the container, only matched, items can be sent into.
During the transferring by human beings, workers will use the handheld reader to the last confirmation.
After finished all the process, and all information is correct, workers will confirm. While the new inventory report will generate.
If the items transfer with carton one by one, it’s better to use RFID handhold read to check every detail instead of a fixed one.
