What is RFID technology? Radio Frequency Identification RFID is a non-contact automatic identification technology, radio frequency signal through the automatic target recognition and access to relevant data, to identify work without human intervention, can work in a variety of harsh environments. RFID technology can identify the high-speed moving objects can also identify multiple tags, the operation quickly and conveniently.

RFID is a simple wireless system, only two basic components, the system used to control, detect and track objects. System consists of an interrogator (or reader) and a lot of transponders (or tags) component. Classification of RFID at RFID applications were divided into low frequency (LF), high frequency (HF), Ultra High Frequency (UHF), microwave (MW), the representation of the corresponding frequencies were as follows: The following low-frequency 135KHz, HF 13.56 MHz, UHF 860M ~ 960MHz, microwave 2.4G (now China Mobile, China Unicom, China Telecom's mobile payment to promote RF-SIM card technology is the application of the frequency, and that the core technology to master the technology in the National, in the Division Telecommunications Union and other Chinese enterprises in the hands, there may be generalized to international standards), 5.8G RFID are two ways of energy supply in accordance with passive RFID, active RFID, and semi-active RFID. Passive RFID read and write short distance, low prices; active RFID reader can provide further distance, but

RFID an essential component? RFID tags commonly known as electronic tags, also known as transponder (tag, transponder, responder), according to the work can be divided into active (active) and passive (passive) two categories, this study of passive RFID tags and systems. Passive RFID tags by the tag or chip and tag antenna coils, the use of inductive coupling or electromagnetic coupling principle backscatter and the reader realize the communication between. RFID tags store a unique code, usually 64bits, 96bits or higher, much higher than its address space can provide the space bar, so the items can be item-level coding. When the RFID tag reader into the role of regional, to be based on principles of inductive coupling (near field scope) or the electromagnetic backscatter coupling principle (within the far-field effect) at both ends of the tag antenna potential difference is induced, and the label chip to form a weak current path, if the current strength exceeds a threshold, it will activate the RFID tag chip circuit to the memory chip on the tag read / write operation, the microcontroller can be further added, such as passwords or anti-collision algorithms and other complex functions. The internal structure of RFID tag chip includes the RF front end, analog front end, digital baseband processor unit and EEPROM memory cell of four parts. Reader, also known as readers, interrogator (reader, interrogator), is the RFID tag read / write operation of equipment, including RF modules and digital signal processing unit in two parts. RFID reader system is the most important infrastructure, on the one hand, RFID tags return to the weak electromagnetic signals through the antenna into the radio frequency reader module is converted to digital signals, then through the reader of its digital signal processing unit shaping the necessary processing, and finally demodulated from the information returned to complete the identification, or RFID tag read / write operations; the other hand, the upper middleware and application software to interact with the reader, the implementation and realization of operating instructions Data Summary upload. Uploading data, RFID tag reader will have to re-atomic event terms to filter or simple filtering process for the reader to the event and then upload to reduce the middleware and application software and data exchange between traffic, so many readers are also integrated microprocessor and embedded system, and part of the middleware functions such as signal state control, and parity error checking and correction. Presents the future of intelligent reader, miniaturization and integration trends, will also have more powerful front-end control functions, such as industrial site directly interact with other devices even as the controller for online scheduling. Internet of Things, the reader will be both communication, control and computation (communication, control, computing) function C3 core equipment [3]. Antenna (antenna) is the RFID tags and readers space between the RF signal propagation and the establishment of wireless communication devices connected. RFID system includes two antennas, one is the antenna on the RFID tag, and RFID tags because it has been integrated as one, it is no longer a separate discussion, and the other is the reader antenna, the reader can be placed within , also with the reader through the coaxial RF output port. The current separation of the antenna transceiver products use more technology to achieve the integration of transmit and receive functions. Antenna in the RFID system, the importance of the often neglected by people, in practical applications, the antenna design parameters that affect the scope of RFID system identifies the main factors. Requires not only high performance antennas have good impedance matching characteristics, but also the characteristics of the environment under the direction of application characteristics, polarization and frequency characteristics were designed [4-7]. Middleware (middleware) is a message-oriented, client applications can accept requests, one or more of the specified reader and receive operation was launched after processing the resulting data to the application of specialized software to return. Middleware in RFID applications, in addition to shielding the underlying hardware brings a variety of business scenarios, the hardware interface standard for the reliability and stability problems caused, but also that the upper layer application software to provide multi-layer, distributed, heterogeneous information environment, business information and management information of the collaboration. Memory database middleware can also one or more reader reader event filtering, aggregation and calculation of the application software to abstract the business logic of the information constitutes a meaningful business events to meet clients from multiple search, publish / subscribe and control requests. Application software (application software) is a direct application for the RFID end-user interactive interface to help users complete the instructions on the operation of the reader and the logic of the middleware settings, step by step into the RFID users atomic events understanding of business events, and use the visual interface to display. As applications of different application areas need to be tailored to different enterprises, it is difficult to have the versatility. Evaluation criteria from the application, the user application software to determine end user experience is a success or failure of RFID application case one of the decisive factors. The basic RFID system components and functions of central database system, system components, safety management system of planting and breeding, production and processing of safety management systems, food supply chain management system, monitoring system, food security information service system based on the composition of plant breeding through the production, processing production, circulation and consumption of information technology links to information set up to achieve the internal production process control and safety aspects of the flow of real-time monitoring, the food traceability and recall. The system functions 1. System management and central data 1) data backup and recovery 2) user permissions, password management, 3) operation log, retain traces of 4) Classification of Library and sample the food bank 5) food production unit property database 6) food safety standards and safety indicators 7) food production and management information 8) food safety monitoring and inspection data 2. Care management of farms growing field of data management center upload, regulatory authorities can be real-time monitoring. Includes the following features: 1) maintenance and management of food: for this kind of farm or buy the livestock and poultry, fruits and vegetables, fish and other basic information to establish file and electronic tag identification; 2) growth management: According to the standard parameters to determine The development and state of health, nutrition adjustment measures and farming methods; 3) feeding and management: records of the breeding situation, look at the different stages of growth and development of nutritional needs, the choice of keeping a reasonable formula; 4) reproductive management: records of genealogical information and breeding information ; 5) disease management: According to the corresponding management standards, the establishment of disease files; 6) quarantine management: establishment of quarantine and immunization files, including vaccines, given medicines, etc., all kinds of illicit drug information embedded in the system, to prevent animals slaughter in the off-drug period, to eliminate the source of pollution. 3. Safe production and processing of the system are mainly carried out on the kinds of food production and processing of farm management, the specific terms of livestock, poultry, fish and other meat slaughtering and production and processing, fruit and vegetable selection of cereals and other food processing of rice, milk production and dairy processing, beverage production and so on. In the production and processing sectors in the planting and breeding areas identified in the tag information transmission into the production and processing of information chain, acquisition by management of production and processing standards and norms, the information on the different nodes, uniquely identified by electronic tags, and the information sent to the logistics segments. 4. Supply management and logistics primarily for warehousing and distribution management, production and processing through the bar and shop in the supply chain traceability system established. In logistics, goods or goods information recorded in the pallet box labels. This bar code system can be clearly informed of the tray or container of goods each separate location, identity, storage and transportation history, destination, duration and other useful information. Bar code system in the supply chain can provide detailed data the actual goods and goods with a complete physical link between the identity of the user can easily access these items completely reliable information. Efficient through the bar code data collection, warehousing and logistics will be timely feedback to manufacturing, to guide production. 5. Sales Management in the sale of food into the terminal, according to the specific situation analysis, the use of existing mature bar code technology. 6. Quarantine control, not only in plant breeding, production and processing process of inspection and quarantine, the quarantine monitoring system based on bar code is also implemented using the crossing, and monitoring chain extension to the supermarket, monitoring object covers all types of food. 7. Basic information of the system as a unified resource publishing, food safety, information sharing of data service network, providing a full range of food safety data information sharing and service. Information for all aspects of the main query, food safety monitoring and analysis, incident prevention, and can be deployed to consumption such as supermarket. By the final product quality and safety code scanning electron can check to purchase the food supply chain information, you can also back up the layers to finally identify the problem, this method is mainly used to recall the products in question the basic RFID technology How does it work? Basic working principles of RFID technology is not complicated: label into the magnetic field, the receiver interpret the RF signals emitted by virtue of the energy obtained by the induced current is stored in the chip sends out the product information (Passive Tag, passive tags or passive tags) , or take the initiative to send a signal frequency (Active Tag, active tags or active tags); readers read the information and decoded and sent to the central information system for the data processing. A complete set of RFID system is from the reader (Reader) and the electronic tag (TAG) is the so-called transponder (Transponder) and application software systems composed of three parts, and its working principle is to launch a specific frequency Reader radio wave energy to the Transponder, Transponder circuit to drive the internal data sent, this time to receive Reader will interpret the data sequence, given the application handled accordingly. The RFID card reader and electronic communication between the tags and the way to look at energy in general can be divided into induction, inductive coupling (Inductive Coupling) and backscatter coupling (Backscatter Coupling) are two most common low-frequency RFID used first type, while the higher frequency of most of the second approach. Reader technology based on the use of different structure and can be read or read / write device is RFID system information control and processing center. Reader is usually coupled modules, transceiver modules, control modules and interface modules. Reader and transponder with half-duplex communication between the general exchange of information, while a passive reader transponder through the coupling to provide energy and timing. In practical applications, can be further achieved through Ethernet or WLAN and other identifying information of the object collection, processing and management features such as remote transmission. RFID transponder is a system of information carriers, the current transponder mostly by coupling the original (coil, microstrip antennas, etc.) and micro-chips passive unit.

What makes such a respected retailer RFID? According to Sanford C. Bernstein analysts estimate the company's retail business, through the use of RFID, Wal-Mart could save $ 8,350,000,000 per year, mostly because the bar code does not require the purchase of artificial view of the labor cost savings. While other analysts believe this figure $ 8,000,000,000 too optimistic, but there is no doubt that, RFID can help solve the problem of the two largest retail trade: goods out of stock and loss (due to theft and supply chain to be disturbed for the loss of product) , and now is the theft of a single Wal-Mart one-year loss of almost 20 billion U.S. dollars, if the turnover of a legitimate business can achieve this figure to 1,000 in the largest firms in the United States ranked list 694.

RFID reader devices to read and write device only when there is, RFID can play its role. RFID reader RFID reader equipment, rfid reader, RFID reader modules, currently on the market are relatively high cost CY-TZB-203, CY-TZB-208, YW-201 and YW-601U and YW-601R and so on. These devices can read or write RFID data, and do a very good encryption. Distance are CY-RFS-205, CY-RFS-209,paul smith wallets, WV-CID1500, WV-VID1500 distance to 1.5 km. Application of RFID technology market, according to analyst estimates Chong Yi, in the radio frequency identification (RFID) technology, mainly low-frequency, high frequency, UHF, HF and UHF applications where wider. High-frequency (HF) reading and writing machines, generally consistent with ISO18000-3, ISO15693, ISO 14443A / B and many other international standards, can be widely used open-access, open attendance, meeting attendance, barrier-free access, valuables management, management of scenic spots, digital, digital libraries library management, medicine management, product security, logistics and supply chain and other areas. RF printer (RFID Printer) with the surface of the electronic label printing plain text messages in real time, read / write tags in the function of electronic data, which can easily reading and manual reading machine can be widely used in logistics, transportation, production automation, health care, library management and livestock management. RFID system includes at least electronic tags and readers in two parts. RFID reader (the reader) through the antenna and the RFID tag for wireless communications, can be achieved for tag identification and memory data read or write operation. Typically contain high-frequency reader module (transmitter and receiver), the control unit and the reader antenna. RFID reader can be divided into several low-frequency readers, high-frequency reader, UHF reader, dual-frequency reader, 433MHz active reader. The working principle of RFID: radio frequency identification systems, RFID tags, also known as radio frequency tags, transponders, data carriers; reader, also known as read out devices, scanners, communications devices, readers (depending on whether the wireless tag rewrite data). Electronic tag and reader device by coupling between the RF signal space (no contact) coupling, the coupling channel, according to the timing relationship, to achieve energy transfer, the exchange of data. Occurred in the electronic tag reader and the coupling between the RF signals There are two types. (1) inductively coupled. Transformer model, through the space to achieve high-frequency alternating magnetic field coupling, based on the law of electromagnetic induction, as shown. (2) Electromagnetic backscatter coupling: Radar principles model, launched out of the waves, hit target reflection, and bring back to the target information, based on the propagation of electromagnetic waves in space. Inductive coupling in general suitable for low frequency radio frequency identification system to work closely. The typical working frequency: 125kHz, 225kHz and 13.56MHz. Recognition distance is less than 1m, the typical distance of the 10 ~ 20cra. Electromagnetic backscatter coupling, generally suitable for high-frequency, microwave, radio frequency identification systems for long range work. The typical working frequency: 433MHz, 915MHz, 2.45GHz, 5.8GHz. Recognition distance is greater than 1m, the typical distance of the 3-l0m liquid metal and the impact of environment on RFID ultra high frequency RFID (UHF) tags because of the electromagnetic backscatter (Backscatter) characteristics of metal (Metal) and liquid (Liquid) and other environmental sensitive, the frequency of such work can lead to passive tags (Passivetag) is difficult in a liquid metal surface of an object or work environment, but the development of such problems as the technology has been fully resolved, for example, Han Shuo ( SONTEC) label company that is developed in the metal or liquid environment can be carried out under the application of well-read passive tags products, to facilitate application of the above cases, the environment or to deploy RFID. Passive tags and active tags Chong Yi technology market, according to different analysts estimate that 80% of the market for the passive tags, less than 20% of the active tag. Can be divided into active RFID tag (Active tag) and passive electronic tags (Passivetag). Active RFID tags built a battery, no built-in battery passive RFID tags. For the active electronic tag, according to label contents are different battery-powered electronic tags can be subdivided into active (Active tag) and semi-passive tags (Semi-passive tag). Work initiative, also known as active RFID tags, labels, work entirely by internal battery power supply, while the energy supply of the battery label partially converted to electronic tag and reader communication required for RF energy. Semi-passive RFID tags inside the battery only requires power to maintain data within the circuit or the tag chip auxiliary voltage required for the support of the label itself consumes very little power to the circuit. Before the label not to enter the work state, has been in hibernation, the equivalent of passive tags, labels, small internal battery power consumption, so the battery can be maintained several years, even up to 10 years in force; when the tag reader to read out into the zone by reading the RF signals emitted by excitation into the working state, the tag and reader information exchange between the energy supply to support the reader's RF energy-based (reflection modulation), the label inside the battery cover tab main function is to location of the RF field strength less than the label inside the battery's energy is not converted to RF energy. Passive RFID tags (passive tags) no built-in battery, read the reader's scope, the electronic tag in a passive state, the reader read range, the electronic tag reader, the radio frequency emitted from the energy required to extract the power of their work. Passive RFID tags are generally reflective modulation using the information to complete the electronic tag reader transmission. Features 1. With its own battery-powered active tags, read / write distance away (about 100 meters to 1,500 meters), larger and more expensive than passive tags, also known as active tags, generally have read far distance, the need to replace the battery runs out of energy. For example: CY-RMZ-206, CY-RMZ-208, CY-RMZ-210 2. Passive electronic tag reader sent in the received microwave signal, some of the microwave energy into direct current for their own work, generally do to the maintenance-free, low cost and has a long service life, smaller than active tags and lighter, read and write distance is close (about 1mm ~ 30mm), also known as passive tags. For example: CY-RMZ-209 compared to active systems, passive systems to read and adapt to the movement of objects from a slight speed limit. Development of RFID RFID in China, the basic technical principles originated in World War II, the Allies used the first radio data technology to identify enemy aircraft and warships of both sides. After the war, due to higher costs, the technology has been mainly used in military field, did not soon be used widely in civilian areas. Until the eighties and nineties, with the chips and electronic technology to enhance and spread to Europe began to take the lead in RFID technology to the road toll and other civilian areas. To the twenty-first century, RFID ushered in a new period of development, the value of civilian areas in the world began to get wide attention, especially in Western developed countries, RFID technology widely used automation, access control, road toll , parking management, identification, cargo tracking, and other civilian areas, and its new range of applications is still expanding, one after another. Beginning of this century, RFID has already begun in China, the application of exploratory and soon received strong government support, June 2006, China issued a the development of the strategic level. The end of 2008, China participated in hundreds of RFID-related businesses at home, and has formed a label and equipment from manufacturing to software development and integration of a relatively complete industrial chain of RFID, according to expert estimates, in 2008 China's output reached 80 billion RFID-related yuan, and will maintain rapid development of the next 5-10 years. Currently, RFID in China, has been applied in many areas, including logistics, tobacco, medicine, ID, Olympic tickets, pet management, etc., but in terms of our daily life experience, it seems very far away from us, or RFID. In addition to second-generation ID card, we often feel that RFID is difficult in our lives there. This in the end is why? Actually, it is very simple, even though RFID is rapidly been applied in various fields, but the relative economic size of our country, and its wide range of applications not yet reached the extent of RFID applications even in the relatively large number of transport and logistics industry, but also still in the point distribution of the state, the state failed to meet the plane. Is often the leader in the industry to maintain its competitive position and the first to try this new technology, and more enterprises are still holding the attitude of wait and hesitation. Or in the logistics industry, for example, application of RFID technology can greatly improve the efficiency of logistics operations, such as speeding up the goods out of storage time, reduce on-site operators to achieve fast and accurate inventory, accurate location tracking in goods, but now, in the real implementation of RFID technology in China's logistics business is also one of the few. Since the economic crisis, many of the RFID industry have begun to cast doubt on the future development of the industry and disappointment, then in the end what factors hinder this emerging industry in China's development? First, the general information of enterprise level is not high, hindering the RFID fully play its role. RFID as a means of information technology, its basic function is to achieve rapid collection of data precision. The data collected, it must be analyzed further processing in order to achieve greater efficiency and lower overall cost effect. In other words, RFID implementation, it often requires a certain level of enterprise information, so that existing RFID systems and enterprise ERP, CRM integrated with other information in order to fully play its role. Second, RFID implementation costs are still relatively high, prohibitive for many companies. Not only for Chinese companies, even for western companies, RFID's high cost is a huge obstacle. As stated earlier, RFID and technical principles have 60 years ago, but until the latter part of last century, RFID application was gradually extended to civilian areas, is high cost hinders the practical application of RFID technology. In China, a RFID tag is generally more than the 1 yuan, ETC on-board unit to 400 yuan, making high-cost RFID has a great return on investment risk and make the most of limited high-value or high-margin area of commodities. Again, the industry standard has not yet unified, would be implemented will bring about uncertain risks. Despite the early origins of RFID, but there are no technical standards for a global unified China started late in the field of standards development, as related to national economic interests, I believe the standard of the competition will continue for some time. In this case, the rash investment, will inevitably bring significant business risks. Blu-ray DVD standards battle to obtain the victory, giving HD-DVD camp, enormous damage is in dispute industry standard in the enterprise had to carefully consider the issue, which is a lot of companies on the implementation of RFID wait and see attitude reasons. Finally, our supply chain development is still in its infancy, but also hindered the practical application of RFID. Compared with Western companies, due to technical and management at a disadvantage, the existence of excessive competition in most industries, price becomes the primary means of market competition, which led many manufacturers to maintain profit margins in the very low levels, the industry supply chain downstream co-operation between enterprises are often greater than the game. The RFID technology is only in the implementation of the entire supply chain collaboration, supply chain transparency and sharing of information in order to maximize the role of RFID, which is also very difficult to achieve under the present circumstances. In addition, one of the main benefits of RFID implementation is to save labor costs, Wal-Mart said its RFID save billions of dollars each year manpower costs, while lower wages in China makes a lot of companies do not have the enthusiasm to implement RFID technology. Although the degree of information of Chinese enterprises is still relatively low at present, but the pace of Chinese enterprises fairly quickly. This year, China has entered more than 40 Fortune 500 companies, more domestic companies are rapidly growing multinational enterprises, the increasingly complex management requirements of these enterprises must rapidly advancing information technology, Chinese companies at this point after a certain advantage, and corporate information are bound to bring good opportunities for the development RFID. With the process of enterprise information, RFID applications will be from point to plane, and gradually extended to wider areas. The cost of RFID implementation, RFID applications with the necessity to promote and market expansion and gradually reduce, RFID applications will be from the current tray or box full of cargo tracking and gradually extended to the level of a single product cargo tracking. Finally, from the industrial supply chain perspective, the countries are to promote industrial upgrading, is to enable Chinese companies to produce more high-tech, high value-added, high margin products, and these areas, it is RFID arena. Industrial upgrading will lead to enhance the market competitiveness of Chinese enterprises, and gradually increased by a single enterprise competition for the industry supply chain competition. Next few years, a number of domestic RFID companies, such as: creating Yi technology, Invengo, Shanghai Hua Hong, Victoria Deep Group .... grow. In the next few years, we will see, RFID implementation will get rid of implemented only by the predicament of individual enterprises, and show for the enterprise lies the implementation of the whole supply chain collaboration, RFID's benefits will be greatest degree of play. All these, we also suspect that the development of RFID in China, it? RFID and the relationship of things of things (Internet of Things), refers to the variety of information sensing devices, such as radio frequency identification (RFID), two-dimensional code, global positioning systems and the Internet combine to form a huge network to facilitate the identification and management, RFID tag is the core technology. A complete industrial chain including standard RFID, chip, antenna, packaging labels, writing equipment, middleware, application software, system integration, one of the key technology is the chip design and manufacturing. Universal chip design and manufacturing technology owned by foreign Philips (Phillips), Texas Instruments (TI), Amtech Corporation and other companies. RFID applications are open loop from closed-loop market to market, similar to the early Internet, the process of local area network to the Internet. RFID can be applied to many areas, the label cost is a major obstacle to the promotion, RFID is still looking for new profit model. Wal-Mart is the logistics and supply chain industry RFID development of strong promoters. GNU Radio is free software development tool suite. It provides operation and signal processing module, it can be easily produced by low-cost radio frequency (RF) hardware and general-purpose microprocessors implement software defined radio. The kit is widely used in amateur, academic institutions and commercial organizations to study and build wireless communication system. The main application of GNU Radio is written in Python programming language. But the core of the signal processing module is C + + floating-point operations in a microprocessor with built on. Thus, developers can quickly build a simple real-time, high-capacity wireless communications systems. Although its main function is not a simulator, GNU Radio frequency RF hardware components in the absence of the situation under the support of pre-storage and (signal generator) to generate the data signal processing algorithm.
