RFID scheme selection of the hottest RFID technolo

  • Detail

Radio frequency identification technology RFID scheme selection must follow three principles

radio frequency identification technology (RFID) can be said to be one of the few revolutionary technologies in the computer field in recent years. Its application is all inclusive and is considered to be one of the hottest Star Industries in the world in recent years. Relevant experts predict that the global RFID market will reach $300billion in 2010. Through RF signal, users can automatically identify the target object without visible light source; It has penetrability, can read data directly through external materials, protect external packaging, and save unpacking time; Moreover, this technology can process multiple RF tags at the same time, which is suitable for batch identification occasions; And it can track and locate the object attached to the RFID tag and provide location information. Therefore, RFID technology has many inherent advantages in supply chain management, and has become a bright spot in many supply chain management solutions. So how does RFID apply in supply chain management, and what should users pay attention to when selecting models

why has RFID become the "focus" and "Star" of people's attention in such a short time? What kind of magic can it do in the field of supply chain management

why does RFID become a "sweet cake"

At the beginning of last year, Wal Mart, the global retail giant, asked its suppliers to provide RFID tags for all goods in early 2005. So what is RFID and why it is favored by Wal Mart

with the rapid development of computer technology, electronic information technology is more and more widely used in all walks of life, and the logistics industry is no exception. The traditional way of collecting logistics information is to check the tickets and then input the data on the tickets into the computer. This process is time-consuming and laborious, and the existence of various wrong data may be caused by various human errors, which will affect the reliability of the collected information. The automatic identification input technology has made great progress in the automatic transmission of material coding and material information. Automatic identification technology uses computers for automatic identification, which increases the flexibility and accuracy of input, makes people get rid of complicated statistical identification work, and greatly improves the efficiency of logistics information collection

rfid technology is a new automatic identification technology rising in recent years. RFID uses radio frequency for non-contact two-way communication, so as to realize the identification of objects, and the collected relevant information and data are transmitted remotely through wireless technology. Compared with the bar code technology widely used at present, RFID has the characteristics of long reading distance (several meters to tens of meters), strong penetration ability (information can be directly read through the packaging box), anti pollution, high efficiency (multiple labels can be processed at the same time), and large amount of information

The emergence of RFID technology makes reasonable product inventory control and intelligent logistics technology possible. Some analysts believe that industrial applications in logistics and production are the strongest areas in the RFID chip market. According to the data provided by allied business intelligence, a market research institution, these applications will account for more than 50% of the entire RFID transceiver market by 2007, and the global sales will exceed 1.1 billion euros

rfid technology has blown a whirlwind in the field of supply chain management. It will be revolutionary to promote the supply chain management solution, and the active follow-up of major mainstream manufacturers has played a role in promoting the application of RFID

rfid solutions focus on integration

p: integrate ERP and SCM functions with RFID

as a global large enterprise management and collaborative commerce solution supplier, SAP company is also a leading supply chain management solution provider. SAP recently announced the launch of the first radio frequency identification (RFID) supporting solution for supply chain management to help enterprise management read and write data through RFID tags, and promote supply chain management to a new level

By integrating ERP and SCM functions with RFID applications, SAP's solution enables enterprises to track and record the entire supply chain using the data captured by RFID tags in business processes

this RFID solution launched by SAP is based on Java technology and built on SAP web application server (SAP web as). It is an integral part of SAP NetWeaver technology platform, which can ensure seamless expansion and integration into Sa's IT environment where gas medium is insulated for at least 30 minutes) P and non sap

a typical example of SAP using RFID technology in the actual environment is the Metro Group future store initiative, of which sap is a founding member. SAP works with more than 40 partners in the Metro Group, Intel, and the technology, consumer goods and service provider industry to implement leading technology for retailers in the future stores of the Metro Group. The store was officially opened in Germany on April 28, 2003. If the added value is high, it can only indicate that the technology content is high. In the future, about 1700 products sold in the store will have RFID tags to track and record items, so as to establish a strain supply chain from the distribution center in Essen to the store

2. Oracle: in collaboration with existing Oracle products, Oracle recently released its sensor based service toolkit and connector. The toolkit can help enterprises capture, manage, analyze and respond to RFID data. The software also contains a quick configuration package, which can support some specific processes of specific customers, such as advanced shipping notification

the software can work with Oracle's next-generation Oracle 10g database and application server, and 11i e-commerce suite. Oracle also announced that its next version of warehouse management software will support RFID to enhance inventory control

the purpose of Oracle is to enable enterprise users who have used Oracle products to use RFID technology for supply chain management without being forced to buy some middleware and consulting services

3. Philips: wide range of applications

Philips Electronics Group launched RFID semiconductor products with a new generation of supply chain management applications - Philips icode EPC and ucode HSL chips, which can provide RFID solutions for all major supply chain management applications. Philips icode EPC chip can realize the reading speed of up to 200 tags per second, and can automatically store information, which greatly benefits the logistics and supply chain system

Philips ucode HSL (ultra high frequency smart tag) is very suitable for long-distance applications, such as container and container tracking in the field of supply chain management and logistics applications. It can read 50 Tags per second. Ucode HSL is Philips' first ucode integrated circuit product in the UHF and 2.45GHz range, so that the same label can be used anywhere in the world with UHF. Using UHF RFID, the reading distance is up to 3.5 meters under the condition of only a single antenna reader, and the reading distance at the entrance can be up to 7 meters, but this needs to be determined according to the settings of different areas. The biggest advantage of long-distance reading is that the entire container and container can be sensed by the reader when they pass through the freight warehouse, so there is no need to scan each individual cargo

Philips' RFID product series has many important characteristics of supply chain management and logistics market, such as fast reading/transmission, standard compatibility, anti-collision and providing manufacturers with options for single cargo security. Through numerous partners in all RFID frequencies, Philips provides a complete set of solutions for supply chain management and logistics market, covering all RFID frequency bands (including less than 135KHz, 13.56MHz, UHF (860 to 930 MHz) and 2.45 GHz). Philips' customized products cover all transmission frequencies, and integrated circuit products can meet various applications including asset management, transportation, supply chain management and retail

4. Infineon: focus on integration

Infineon Technologies AG has set up RFID solution exhibition, evaluation center and system lab in Graz. This center is a key step in the company's strategy of providing RFID solutions. At the same time, the center will also display a complete RFID system for logistics applications

Infineon's RFID system integration platform is called you-r open (operating environment) platform. This is an operation system environment specially developed for RFID technology, which can connect the existing logistics IT infrastructure of the enterprise with the logistics system supporting RFID. You-r open supports RFID infrastructure - from smart tags to readers, PCs, and servers, while also connecting it networks

Infineon can provide relatively comprehensive solutions for RFID based logistics applications, including smart tag technology that integrates RFID chips and antennas into paper or plastic at the same time, smart tag readers, system platforms that integrate RFID logistics applications into the company's operation process, and development, implementation, activation and maintenance services related to logistics systems. Infineon RFID system solutions can also be adjusted for applications in automotive and textile industries, so as to meet the special requirements of these industries in the logistics process such as production and supply chain management

facing so many schemes, how should users choose? When looking for the most suitable scheme, enterprises should pay attention to three basic factors besides the common considerations of performance, price and service

three principles of model selection

1 Meet the national standard

at present, RFID technology is not an international unified standard. The EPC (electronic product code) Global Association of the United States is formulating the EPC wireless interface protocol of the United States, while Japan, relying on its world-class microelectronics industry foundation, is likely to formulate its own standards. On the other hand, China's national standard working group for electronic labels is also developing China's RFID standard

therefore, when choosing RFID solutions, enterprises must consider the national environment of specific applications. In today's globalized production, the supply chain is likely to span several countries, so the supply chain management system needs to take into account the standards of all relevant countries to avoid unnecessary legal disputes

2. Suitable for the application environment

the frequency used by RFID readers to send RF signals is called the working frequency of RFID system. According to different frequencies, RFID system can be divided into low frequency, high frequency and ultra-high frequency. The low-frequency and intermediate frequency systems have short operating distance and low cost, while the high-frequency system has long recognition distance and high data reading and writing speed. In terms of the basic working principle of RFID system, RFID system can also be divided into full duplex system, half duplex system and timing system. RFID tags can also be divided into active and passive

different RFID systems determine their different applications. Therefore, when selecting schemes, users need to choose the most appropriate system scheme according to their own use environment to prevent the waste of investment

3. The supply chain management system is closely related to the enterprise information management, so the specific RFID scheme must be compatible with the enterprise's existing information system (such as ERP). It is gratifying that major ERP providers in the world have or are developing their own RFID based supply chain managers
