RFID radio frequency identification is a non-contact automatic identification technology. It automatically identifies target objects and obtains relevant data through radio frequency signals. The identification work can work in various harsh environments without manual intervention. RFID technology can identify high-speed moving objects and can identify multiple labels at the same time, and the operation is quick and easy.
Short-range RF products are not afraid of harsh environments such as oil stains and dust pollution. Barcodes can be used in such environments, for example, to track objects on the factory's assembly line. Long-range radio frequency products are mostly used for traffic, and the recognition distance can reach several tens of meters, such as automatic charging or identification of vehicle identities.
Application of RFID technology
a. In the retail industry, the use of bar code technology makes tens of thousands of product types, prices, origins, batches, shelves, inventory, etc.
b. The use of automatic vehicle identification technology enables roads, bridges, parking lots and other toll collection sites to avoid queuing and clearance of vehicles and reduce waste of time, thereby greatly improving the efficiency of transportation and the capacity of transportation facilities.
c. In the automated production line, all aspects of the entire product production process are placed under strict monitoring and management;
d. In the dust, pollution, cold, hot and other harsh environments, the use of long-range radio frequency identification technology has improved the inconvenience that truck drivers must get off the train;
e. In the operation and management of buses, the automatic identification system accurately records the arrival and departure time of vehicles at each station along the route, providing real-time and reliable information for vehicle scheduling and overall operation management.
What benefits does RFID technology bring to corporate logistics and supply chain management?
An electronic tag is a tool that increases the efficiency and accuracy of recognition, and it will completely replace bar codes.
Take Nokia, a well-known mobile phone manufacturer, as an example. Nokia is the first to test RFID projects in Finland. It uses a commercial thermal printer to affix a color-coded label to a mobile phone product. The printer is connected to the customer's shipping process system and passes information through a smart reading board to a secure web server. In the material procurement process, Nokia’s parcels were unloaded in a UK warehouse and the information was automatically transmitted to Nokia’s branch material managers’ mobile phones via a barcode reader.
In manufacturing companies, such as Hewlett-Packard, we are working to discover how RFID can help us in the actual manufacturing process. RFID can ensure that they use the right components in their manufacturing. Under the company's existing system, HP employees need to scan the in-process product on the production line and then scan the components to see if they match. After using RFID tags, the correctness of the selected components is automatically ensured by verifying the component series coding. HP is also actively involved in smart and secure trade channel activities, which were created after 911 to ensure the security of cargo containers entering the United States. The project uses active RFID technology to provide real-time visibility into the status, location and security of containers entering the port.
In corporate distribution and retail distribution, RFID has begun to function from the moment the goods leave the warehouse. When the vehicle's cargo leaves the distribution center, the system scans the goods on the trailer so that the store manager can track each shipment from the store's warehouse information system, knowing which goods were shipped and when they arrived. When the trailer arrives at the store, it goes through a scan to see if something is missing, so that it is no longer necessary to check every trailer and the actual number of stats. Once the merchandise is placed on the shelf, when there is a shortage of merchandise on the shelf, the embedded RFID reader sends a message to the store back office system, and then the goods are replenished as needed, thus avoiding the sales loss caused by the shortage of merchandise. In addition, RFID readers can also track the speed of sales of goods and the best and worst-selling merchandise, and have a security anti-theft function. As long as the anti-theft feature in the tag is active, the sensor at the outlet of the store can send out alarm information. At the checkout counter, the anti-theft program is automatically cancelled. At the checkout counter, the tagged goods will go through the last scan and update the inventory at the same time. In addition, the shop's customers can directly understand the products they want and immediately get information about the tagged products. In this way, choosing a DVD or CD is very simple, because customers can scan the product in any electronic convenience store in the store and choose to play video or music clips.
In the past, waiting at checkout counters for a long time was a headache. In the new store, the RFID tag in the shopping cart will tell the store management how many shopping carts are in and out of the store. If the number of shopping carts used in the store increases, more shopping platforms will be opened to meet the requirements of handling a large number of customers.
Wireless operation management system
1, Conveyor sorting
Sorting the goods on the conveyor belt requires the use of multiple antennas to construct an RFID scanning tunnel to increase the initial rate. At the same time RFID readers need access to the conveyor belt or other control host. At this time, the use of Intermec Intellitag RPC reusable RFID tags and Intermec Intellitag IF4 readers can constitute an economical and efficient RFID system.
2, warehouse receipt and delivery
When loading and unloading trays into and out of freight cars and containers, their metal boxes have strong reflections on radio waves, which seriously affects the effectiveness and correctness of RFID reading. The Intermec Intellitag IF5 is an intelligent RFID reader and provides four antenna interfaces for flexible scanning tunnels. Can effectively improve the reading effect and accuracy.
3, tray packaging workstation
RFID readers installed on pallet packaging workstations need to identify and classify the goods on the trays in a timely manner and link them with RFID-identified trays. Intermec Intellitag IF4 is a low-cost solution.
4, over the top to read
The scanning network is composed of a fixed RFID reader and a group of antennas to form a downward-covering scanning network. Large items and trays with RFID tags attached to the top can be read and written efficiently. Especially forklift operations, more convenient and effective.
5, manual mobile operations
Manual move jobs require the assignment of items and complete a series of operations. The Intermec Intellitag IP3 mobile RFID reader and Intermec 700 mobile computer combine to form a mobile operating platform that can simultaneously read and write RFID tags and scan the bar code, and perform corresponding processing, storage and communication. With the power of the Intermec 700, the Intermec IP3 can be built with peripherals and systems for PAN, LAN and WAN for different applications.
6, Forklift moving operation
Forklift mobile operations are the main operating mode for warehouses and logistics centers. Mobile platform consisting of an Intermec Intellitag IF4 fixed RFID reader and an Intermec CV60 on-board computer, especially suitable for pallet goods operations and RFID tag reading and writing
