    In a hospital, if an administrator was looking for a designated patient, it would take a lot of time to look at, check the ward, or look elsewhere in the hospital. To view medical information such as patient medical history, you have to look through a pile of paper. At the same time, for patients who are unclear or seriously ill, leave the bed where they leave the room or leave the hospital and lose. Now, patients who are under critical care have their own smart labels (ie wristbands), each with their name in the patient management system, as well as all medical history, medications, and other information, through a visualized software system. Easy to locate and view at any time. This can help managers save clinical time, monitor and track the patient's location in real time, and limit patients to certain non-safe areas.

    At present, people are paying more attention to the quality of meat products and dairy products. At the same time, people are paying more and more attention to the reliability of the quality of these products. This poses a new challenge for some enterprises and requires enterprises to have a complete Management system for the production of these products, the process of strict supervision and control. However, over the past decade or so, the continuous outbreak of animal epidemics in the world, such as mad cow disease, streptococcus suis, foot-and-mouth disease, bird flu and the like, have posed grave threats to the health and life of the people and have also dealt a heavy blow to livestock husbandry around the world Industry, which has aroused great attention of all countries in the world. To this end, the governments of various countries quickly formulate corresponding policies and take various measures to strengthen the monitoring and management of animals, of which animal identification and tracking has become one of these major measures. For example, the British government has mandated that all kinds of tracking and identification be used for animals such as pigs, horses, cattle, sheep and goats.
     
    The purpose of this system research is to establish a complete, flexible and convenient management system by using Radio Frequency Identification (RFID) technology to improve the modern management level of pig farms. At the same time, it is convenient for managers to promptly solve problems in pork and its products Identify the source of the disease, so as to make the appropriate treatment to avoid the loss of expansion. RFID is a non-contact automatic identification technology, with the characteristics of large amount of data storage, read and write, strong penetration, long read and write distance, fast read speed, long service life and good environmental adaptability. And it is the only automatic identification technology that enables multi-target recognition.

    1 System structure and working principle
     
    RFID-based animal identification and tracking management system consists of RFID radio frequency card, reader and computer network composed of three parts, shown in Figure 1. The reader is generally used as a computer terminal for reading, writing and storing data of an RFID radio frequency card. The reader is composed of a control unit, a high frequency communication module and an antenna. The reader system includes two fixed and handheld. An RFID card is a passive transponder. It mainly consists of an integrated circuit (IC) chip and its external antenna. The RFID chip usually incorporates circuits such as RF front-end, logic control and memory, and some even integrate the antenna together On the same chip.
     
    RFID animal identification system structure The basic working principle of the system is: when a pig with "ear studs" (RFID card) into the reader RF field, the induced current obtained by the antenna is boosted by the boost circuit As the chip's power supply, at the same time, the induced current with information through the RF front-end circuit to detect the digital signal into the logic control circuit for information processing; the required information is recovered from memory access through the logic control circuit back to the RF front-end circuit, and finally Send back to the reader through the antenna.
     
    The computer network obtains the information of pigs in the farm through the interface and integrates the basic functions required for the daily management of the pig farms. All the records, statistics and reports originally involved in the daily management of the pig farms are all done by hand Achieve computer management. The system basically meets the needs of current production management in pig farms and provides information from the macro-decision-making so that managers can understand the pigs in time and accurately
     
    Field management, improve the level of modern management.
     
    The company is located in:
     
    2. "Earrings" (RFID card) installation
     
    At present, the basic methods for installing electronic tags for animals are collar-style, ear-tag, injection-type and pill-type electronic tags,and various tags have their own characteristics and application scope. The cost of a collar tag is too high, whereas injection and pill tags are not suitable for pigs, and so the system uses a "stud" tag. Ear-studded electronic tags not only store more data, but also anti-dirt and rain. The information stored in the "ear nail" radio frequency card includes: the address of the pig farm in the township, postal code, breed information, date of earring wear, quarantine and immunization information, disease information, genealogy and reproductive information, slaughter date, etc. This information must cover the entire life cycle of this pig from birth to facilitate the identification, tracking and management of pigs.
     
    2.1 RFID tag reader implementation
     
    There are two kinds of RFID tag readers used in this system: one is a fixed reader; the other is a handheld reader. The main difference between a fixed reader and a handheld reader is that the handheld reader can read a large amount of RFID tag information and then input the information into the system software platform through the USB interface or the COM port of the pc machine in. The fixed reader after reading the RFID tag information is transmitted to the software platform in real time, without having to store in the reader. Fixed reader is installed in a fixed position piggyback, CAN bus network and software platform for real-time data and information exchange. Handheld reader is very easy to use, after reading the RFID tag information and then concentrated with the Pc machine for data exchange.
     
     
     
     Fixed reader MCU can use 16-bit microcontroller, embedded software platform written in C language. MCU firmware responsible for the entire reader RFID tag identification and read and write control, as well as software platform through the CAN network for communication and data processing. LCD dot matrix display module as a software platform, an auxiliary display terminal. (2) CAN network control module: The CAN bus network has a communication distance of 1.5 krn at a baud rate of 9600, and the communication physical transmission medium is simple. Only two-core twisted pair and can form a bus network, CAN bus network in the twisted pair transmission of physical signals is differential voltage signal, anti-interference ability, transmission distance, control through the CAN network control module to multi-host Way communication CAN network control module is responsible for network status monitoring and network communication arbitration and other work, so that bus network communication to work without blocking.
    (3) 900MHz RF Signal Processing Module: It is responsible for the modulation and demodulation of 900MHz RF signals and the read / write control of RFID tags by 900MHz radio waves. The 900MHz RF signal processing module can be controlled by transmitting energy The RFID tag identifies the sensing distance and uses anti-collision technology to identify multiple RFID tags within the sensing area. The module and MCU control unit through the parallel port connection, MCU can command to control the module for processing.
    (4) The reader can read and write multiple RFID tags, set the read / write distance and direction of the RFID tags, and the reader can judge whether the RFID tags are read or written repeatedly by themselves.
     
    3 System software design
     
    In order to effectively adopt modern management methods and organize production reasonably, we carefully analyze the logistics activities in the pig farms. Through the investigation of a modern pig farm, the management targets in the pig farm include not only pigs, but also pork and its products, feedstuffs and staffs. Therefore, the system has set up 9 functional modules: system management, pigs Only maintenance management, growth and development management, feeding management, reproductive management, disease management, epidemic prevention management, tracking information inquiry and pig farm data management
     
    The entire system platform using C / 5 technology, the database using SQLServer2000, dealing with internal affairs of the system. Front-end development platform using Delphi6.0 design, the system uses multi-threading technology, you can achieve the use of RFID tags on the pig farm reader status monitoring. After several months of operation, the system was in good condition and basically met the expected requirements.
     
    Tag will become the "ID card" of livestock products entering domestic and foreign markets. The introduction of national standards for electronic labels and the widespread application of electronic labels will greatly enhance the logistics management capabilities, quality supervision capabilities, traceability and competitiveness in international trade of livestock products, as well as standardize and purify the livestock product market.
     
    Therefore, further research and use of RFID technology in animal identification and tracking management will promote livestock husbandry to a higher level

    Application of RFID Sensing Technology in Blood Management

    RFID is gradually being integrated with sensing technology. The combination of sensing technology and RFID technology will create an ubiquitous and always-aware "sensor network," which brings a new dimension to the management of medical supplies, especially blood management Opportunity.
    RFID fusion sensor technology for the feasibility of blood management
          The general flow of blood management business: a blood test registration a blood test a blood test a blood bank a library management (component processing, etc.) a blood out of a hospital for patients to use (or made of other blood products). In this process, often involves a large amount of data information, including blood donors information, blood type, blood collection time, place, handlers and so on. A lot of information to the blood management has brought some difficulties, coupled with the blood is a very perishable material, if the environmental conditions are not suitable, the quality of the blood that is destroyed, so the blood in the storage and transportation, quality Real-time monitoring is also crucial. RFID and sensing technology is an emerging technology that can solve the above problems and help blood management effectively.
        RFID technology for each bag of blood to provide their own unique identity, and save the appropriate information for them, the information and background database connectivity, so the blood, whether in the blood collection point, or in the transfer point of the blood bank, or in the use of point hospitals , Can be monitored by the RFID system all the way, the blood in the transfer point of the information can be tracked at any time. In the past, people had to spend time and effort on the library. Before using, people also need to check the information manually. After using RFID technology, they can collect, transmit, check and update the data in large quantities in real time without the need of precise positioning, Library identification, but also to avoid the manual error checking often appear. The RFID non-contact identification feature can also ensure that blood is not contaminated conditions to identify and test, reducing the possibility of blood contamination, it is not afraid of dust, stains, low temperature, can be stored in the blood of special Environmental conditions to maintain normal work.
        Sensing technology is a window of perception, acquisition and detection of information, it can achieve the collection and quantification of data processing fusion and transmission applications. Through the sensor real-time monitoring and collection of the blood environment temperature, the sealing status and the degree of oscillation, the timely processing and reaction of the sensing information through the system can effectively prevent the blood from deteriorating and ensure the blood quality.
    Combining RFID with sensing technology, we can realize the intelligent informationization of blood management by using the RFID sensor tag that can improve the recognition efficiency, realize information tracking, and monitor the quality of articles in real time.

    Application of RFID Sensor Label in Blood Management
        Mainly from the blood out of stock management, blood tracking management, blood quality control management introduced in three aspects, pointed out that RFID fusion sensing technology in blood management in the effective role.
    1 Blood out of storage management
    (1) blood storage
        Staff will blood bags on the conveyor belt at the population passed in turn, the bottom of the conveyor belt installed RFID reader, when the RFID tag attached to the blood bag into the read-write read range, the information on the label is read out, the The middleware is filtered and sent to the backstage database. At the same time, the system displays the blood type, type, specification and other information on the screen at the exit of the conveyer. The staff releases the blood into the designated storage tray according to the displayed content.
        According to the read blood type, type, size, quantity, etc., background system to identify the cargo space in the blood bank, to find the existing specifications and quantity of empty cargo space. This step is achieved mainly by affixing an RFID tag to each shelf and writing information about the type, type, quantity, quantity, etc. of the blood that it should store via the reader, and when there is a blood bag on the shelf On this, the worker sets the RFID tag by using the handheld reader and writer. When the blood bag on the shelf goes out of storage or is displaced, the worker clears the RFID tag with the handheld reader and writer , While the reader installed at the top of the blood bank will read the labels of the shelves under the instruction of the system and find that the shelves that have been cleared and meet the storage conditions will notify the system and the system will put the The specific number is displayed on the screen of the depot, informing the staff which types of blood should be placed on which shelves.
        After being instructed, staff will give all kinds of blood to designated areas for refrigerated storage. At the same time, the reader will be stored in the blood bags of the storage time, the type of storage, sending blood, then blood and other information written to the RFID system.
    (2) blood out of the library
       System issued a shipping order, instructed staff to the designated area to remove the specified type, size and quantity of blood. If the amount of blood taken less staff can use handheld readers directly read blood information; if the amount of blood taken more, staff can use the conveyor belt to send blood out of the library and read its information. Read out the information transmitted to the system, check with the background database, if correct, allowing the library. Out of the library process, RFID system records out of the library, the blood effective date and other secondary information.
        Blood out of the order by the system to read the information to analyze the decision, requiring the same kind of blood in accordance with the principle of first in, out to avoid inventory backlog and blood overdue phenomenon of waste. For the blood bank marked "pending" status of the blood out of the warehouse, in order to ensure the quality of the library out of blood.
    2 Blood tracking management
       Blood tracking management uses a cluster-based hierarchy. Each cluster head is a distributed information processing center, which is used to collect the data of each cluster member and complete the data processing and fusion. Then the data is transmitted to the cluster head of the upper layer and transmitted in turn, and finally all the data are filtered and After the integration of the cluster head toward the top, and its inverse process is the information query process, the data layer by layer, orderly tracking. Here, the head of the cluster at the highest level is equivalent to the blood information center of the whole country, while the cluster heads at the next highest level are equivalent to the blood information centers of provinces, autonomous regions and municipalities directly under the Central Government, and so on. This hierarchical structure will spread the information, to avoid the centralized storage, to solve the problem of excessive information, but also improve the security of the system. Information exchange and delivery directly between the sub-layer and the parent layer, to facilitate the query and tracking.
    The process of depositing blood information is as follows: Firstly, the RFID identification code of each bag of blood is stored in a database of grassroots blood stations, and then the information of the blood station in the grassroots unit is fused to match the identification code with the effective IP The address is saved in the local municipal blood information center database, and then the information of the municipal blood information center is fused, and the identification code and the effective IP address of the municipal blood information center are stored in the local provincial blood information center database, finally Re-integration of the information on the provincial blood information center, the identification code and the provincial-level blood information center effective IP address is stored in the National Blood Information Center database (if necessary, but also the identification code and then the National Blood Information Center The effective IP address is stored in a global database of blood information centers for global blood information interoperability).
    The tracking process of blood information is as follows: According to the RFID identification code, first search the database of the national blood information center for the information of the province to which the blood of the bag belongs, and enter the database of the provincial blood information center according to the found IP address to find the belonging of the blood of the bag City information, according to the found IP address into the city blood information center database to find the blood bag blood belongs to the station, according to the IP address to enter the blood bank database, according to the information which can know the bag of blood current Status is saved in the library or out of the library is used or spoiled, if it is already used, you can further find the user's full information.
    3 Blood quality control management
       Blood is very sensitive to changes in temperature. If the ambient temperature is unfavorable, the blood substances will be destroyed, which will affect the quality of the blood and the shelf life. During storage, delivery and transportation, the blood should also avoid violent oscillation. In addition, the blood packaging should be sealed. If the bacteria are contaminated by punctures or other factors, the blood will be discarded.
    Application of RFID Sensing Technology in Blood Management
    The RFID tag attached to the blood bag will monitor the environment around the blood bag in real time and measure the ambient temperature, pressure, sensation, oscillation and other physical signals at regular intervals and record the measurement data in the tag chip . The system will set a standard range for the label. Once the current measured data is lower than the lower limit of the range or higher than the upper limit of the range, the label will launch the RF signal to activate the alarm device to prompt the staff.

    What is the development trend of RFID technology?

    RFID has gone through more than 50 years and has seen faster growth in recent years. With the continuous improvement of technology, the types of RFID products will be more and more abundant and the applications will be more and more widely. So look forward to the future, RFID What will happen? What trends will be?

     
     With the rapid development of optoelectronic technology, micro-computer technology, image processing technology and pattern recognition technology, especially the mature face recognition technology, biometric technology has been listed as a revolutionary impact on human society in the 21st century One of the top ten technologies. In recent years, the identification of human biological features such as voice recognition, face recognition, signature recognition, fingerprint recognition, palm shape recognition and eye iris recognition has been developed and applied at home and abroad.
     In the past two years, biometrics has been partially applied to many important industries and fields such as public security, security, customs, finance, military, airports, frontier ports, security and so on, as well as civilian markets such as smart access control and time attendance. Experts predict that by 2012, biometric technology will enter a period of rapid growth, and the era of biometric identification has come. Biometric technology will become an important part of RFID and will promote the rapid development of RFID technology.

    Product Electronic Code EPC will become a new representative of IoT technology
     With the economic globalization and the acceleration of information networking, technical products to meet the requirements of single product identification and efficient identification of electronic code EPC (ElectronicProductCode) came into being. EPC system is a complex, comprehensive and comprehensive system, including EPC coding, network, communication protocol and so on. It is based on computer Internet and radio frequency technology RFID. It uses UNITAR coding technology to give each entity a unique Code to construct an IoT that enables real-time sharing of global item information.
     In combination with the EPC technology of RFID and Internet systems, the future will become the main standard for modern supply chain management. The concept of "Internet of Things" that tracks and tracks shipments globally through the Internet has gradually become a new direction for the development of the logistics industry . It can be said that EPC will become an important new technology after bar code technology and RFID and once again change the commodity retail settlement, logistics and product tracking management mode. It can be predicted that RFID / EPC automatic identification technology will bring international shipping logistics and global A revolution in the supply chain will further promote the development of China's automatic identification industry.
     RFID data processing capabilities will be more and more strong, the demand for software is more and more big
     For enterprises using RFID technology, how to effectively deal with the huge amount of data brought by the application of RFID technology to reduce costs and improve management efficiency will be a very urgent issue in the future. So companies need a powerful data management platform that includes back-end databases, applications and the right analytics to handle the huge amounts of data generated by RFID systems. Otherwise, businesses may be overwhelmed by large amounts of data without the benefits of RFID technology.
     The current software is relatively simple in RFID applications, the average cost of not more than 13% of the overall RFID project. In the next few years, with the development of large-scale logistics applications and open-loop applications, massive RFID information processing, transmission and security pose new challenges to system integration and application of RFID technology. Software will be of great importance in RFID project expenditures Part, in some applications, even exceed the cost of the hardware.
     
    This mainly shows that the share of software / middleware in the overall RFID market will continue to increase, becoming a new impetus to the RFID market. Experts believe that the future of RFID system integration software will be embedded, intelligent, reorganization direction, through the construction of RFID public service system will make RFID information resources organization, management and utilization more in-depth and extensive.
     As the status of software / middleware in the RFID system is more and more important, at present, domestic and foreign manufacturers have invested more and more technical research in this area in order to meet the tremendous demand in the future and have achieved some achievements, including Institute of Automation, Chinese Academy of Sciences launched the RFID public service system infrastructure software and blood, food, medicine traceability management middleware, Tsinghua Tongfang ezRFID middleware, ezONEezFramework basic application suite.
     
     
     Nowadays, many countries in Europe and the United States have started to set their own standards one after another. How to make these standards compatible with each other so that an RFID product can be smoothly circulated around the world is an important and urgent issue at present.
    RFID will become safer, more practical and cheaper
     RFID technology in the field of information to have better confidentiality requirements wide application, there are still some technical problems, because the current widespread use of passive RFID systems there is no reliable security mechanism, the data is difficult to keep a good secret . Therefore, many RFID developers are fully engaged in research, take serious security measures, a strong password, coding, authentication and other technologies will be more widespread research and development and application of future want to destroy the RFID, cloning will be very difficult. At the same time, the future of RFID law will be developed and implemented, RFID data will be increasingly protected by law. Illegal access to and use of data and files in RFID tags will be considered a criminal offense.
     Also, RFID / NFC readers in smart mobile devices will make it increasingly widespread for financial transactions of credit / debit cards or e-wallets, mobile micropayments and the like, while printed electronics use organic and inorganic materials, It will also eliminate the need for expensive silicon chips. RFID tags will also be printed directly on the package, making it more widely available for low-value goods - counterfeit or stocked goods - and ultimately cost savings.
     
     So in the future RFID system will not only become more powerful, will also be more effective in addressing industry needs. Some companies are tailor-made for this specific industry, or jointly develop applications, this trend will be further accelerated in the future. In the future, with the increasing implementation experience of RFID vendors and the continuous improvement of technologies, more applications will be provided for the needs of the industry. From retail to warehousing, manufacturing to government affairs, from transportation to finance, and more and more The RFID industry is becoming more and more customized, making it easier.
