The hottest RFID technology in China moves towards

China's RFID technology is moving towards industrialization. Ouyangyu, manager of RFID Business Department of shihuakai e-commerce group, said that looking forward to 2005, China will set off a boom in RFID applications. Whether in terms of RFID training, standard formulation, local and small-scale applications, special applications in some industries, or the standardization of the market environment, the initial formation of the RFID industrial chain will enter a new stage

the domestic industrial chain is in the ascendant

according to Analysys International data, the RFID industrial chain includes seven technical aspects: standard formulation, chip design and manufacturing technology, antenna design and manufacturing technology, chip packaging technology, reading and writing equipment development and production technology, system integration and data management software platform, and application system development

domestic RFID R & D is mainly concentrated in big cities such as Beijing and Shanghai. At present, the RFID industry chain in Shanghai has taken shape, including chip packaging manufacturers such as Shanghai Shenbo and electronic label terminal equipment manufacturers represented by Shanghai Huashen. In the field of system integration and data management software platform, Shanghai Jiaotong University, in cooperation with AutoID China Laboratory and sap, is developing electronic label middleware. As for the development of application system, Shanghai Haiding is developing the application of RFID in the field of commercial circulation. Beijing has made little progress in the independent development of upstream products, but it has developed rapidly in the integration of application systems. Enterprises such as shihuakai and Weishen electronics are very active in this field

at present, the market share of low-frequency RFID, which realizes contactless identification based on the transformer coupling principle, accounts for almost more than 90% of all RFID applications. Its basic characteristics can be summarized as follows: the technical threshold is low, and more enterprises participate; The non-contact distance between the electronic tag and the tag reader is relatively close, and the directivity is not strong; The application cost of the product is low. In general, in the field of low-frequency RFID, there is a good foundation in China, and the application has become mature. In the field of high frequency RFID, the technology and application are still in the primary stage

emerging enterprise leading product standard

has entered the RFID field for more than one year. Shihuakai, with the background of metro, HSBC, Softbank and other shareholders, is a typical system integrator. They are developing the first multilingual reader (Chinese, English, Japanese, Korean) and a software called ID express. This software gives each product made in China a unique ID code, which includes not only the EPC code for the international market, but also the Chinese code specially prepared for the domestic market, as well as the Japanese uid code. These different codes are integrated on the same label. In order to make this kind of label work effectively, shihuakai has designed a price tracking software, which contains the information of domestic suppliers and sellers. In the future, shihuakai hopes to integrate this software with other partners. At the end of December last year, shihuakai successfully launched the first RFID product "weiche No.1". From then on, I believe that RFID technology, low-density plastic film recycling will become the mainstream of waste plastic disposal, and truly enter the car of ordinary people's homes

in terms of standards, due to various reasons, the "national standard working group for electronic labels" established in early 2004 was suspended by the National Standards Commission, and a new RFID standard working group is brewing. At present, relevant enterprises are working with the RFID standard seminar jointly held by 15 ministries and commissions led by the Ministry of information industry

in terms of international standards, in April 2004, the Japanese uid center, one of the three major standards organizations in the world's RFID field, signed an agreement with shihuakai, announcing the establishment of uid China Center. They set the goal to integrate EPC standards and uid standards, and put forward more perfect RFID standard suggestions to the international organization for Standardization ISO. Shihuakai also held a working conference on "RFID standards for global supply chain and logistics" in China with the international organization for Standardization ISO. This is the first time that ISO has held a working conference on RFID standards in China. The three-day meeting passed the draft standard that said the industry has fully recovered and it is too early to apply RFID technology to container containers and pallets. Recently, as the only enterprise representing China, shihuakai also participated in the ISO working meeting on RFID standards. It is reported that in April this year, shihuakai will also invite domestic and foreign professional manufacturers and RFID solution providers to hold the largest RFID Application Exhibition in China. At the same time, we will continue to develop several demonstration pilot projects that have already begun

many parties set off an application boom

wireless and broadband are the development direction of modern communication technology. Within five years, RFID technology will be integrated with 3G mobile, wireless local area, home broadband, digital TV, GPS technology, etc., and will be applied in a broader field. At that time, the polyether polyol unit with an annual output of about 15000 tons and the small paint raw material production unit will also be shut down. Someone once said that "computing will be everywhere" in the future. Now we can say that RFID will be everywhere

2005 is the first year of Wal Mart's enforcement, which will inevitably affect China's manufacturers. In a keynote speech delivered at the RFID World Forum recently, rocky Shi, a consultant of China's radio frequency identification technology (RFID), pointed out that in the future, China will become the leading force in the application and development of RFID technology and the most important user of this technology

rfid system composition

rfid system is mainly composed of three parts: first, the tag part, RFID tag contains a silicon chip and antenna, which can store data information; The other part is the data collector (also known as reader, code reader, scanner, etc.), which is used to scan and obtain the data on the label, read and write for different labels, and record and query the data on the label; The third part is middleware, including some application software, which is used to process the collected data. It can be a database or supply chain system, or it can be a part of enterprise ERP

rfid system is divided into low frequency, medium frequency and high frequency systems according to different working frequencies. The low-frequency system generally works at 100kHz ~ 500KHz, and the intermediate frequency system works at about 10MHz ~ 15MHz. They are mainly suitable for applications with short identification distance and low cost. The high-frequency system can reach the microwave band of 850mhz ~ 950mhz and 2.4GHz ~ 5GHz, which is suitable for the occasions with long recognition distance and high data reading and writing rate
