Talking about the application case of rfid technology

Radio Frequency Identification (RFID), also known as Radio Frequency Identification (RFID), is a communication technology that uses radio signals to identify specific targets and read and write related data without the need to identify mechanical or optical contact between the system and a particular target. .

For radio frequency, it is usually microwave, 1-100GHz, suitable for short-distance identification communication.

RFID readers are also mobile and fixed. At present, RFID technology is widely used, such as: library, access control system, food safety traceability.

Radio Frequency Identification (RFID) is a wireless communication technology that uses radio signals to identify specific targets and read and write related data without the need to identify mechanical or optical contact between the system and a particular target.

The radio's signal is transmitted from the tag attached to the item by an electromagnetic field that is modulated into a radio frequency to automatically identify and track the item. Some tags receive energy from the electromagnetic field emitted by the recognizer when they are recognized, and do not require a battery. The tag itself has a power source and can actively emit radio waves (electromagnetic fields that are modulated into radio frequencies). The tag contains electronically stored information that can be identified within a few meters. Unlike barcodes, RF tags do not need to be within the line of sight of the recognizer, but can also be embedded within the object being tracked.

Radio frequency identification technology is used in many industries. Attaching the label to a car that is in production, the factory can easily track the progress of the car on the production line. The warehouse can track where the medicine is located. RF tags can also be attached to livestock and pets to facilitate positive identification of livestock and pets (positive identification means preventing several animals from using the same identity). The RFID-enabled identification card allows employees to access the locked building section, and the RF transponder on the car can also be used to collect the toll road and parking lot.

Some RF tags are attached to clothing, personal belongings, and even implanted in the human body. Because this technology may read personal information without my permission, this technology may also infringe on personal privacy concerns.

Application case of rfid technology

RFID is a simple technique that allows any object (OOI) to be identified. The use of RFID tags with unique identification codes, in addition to the simple application of the label to the entity, can be easily embedded into the object (OOI) for identification. RFID is a radio frequency technology that transmits through the antenna between the tag and the reader. In this way, label related information on the subject matter (OOI) can be easily obtained.

When the circuit in the RFID tag has sufficient energy, it will begin to transmit and link signals within the reader's receiving range. This method is different from other static identification technologies, it is a LOUD ID technology. This feature makes certain inventory management and location issues simple, which is why RFID is well-suited for tracking, tracing, and inventory management functions.

When using RFID to solve a specific problem or to improve a specific solution, it means using an RFID application system, including a hardware part tag, an antenna, a reader; and a software application system. The RFID tag gives the object (OOI) an identifiable identity, the antenna and reader provide the ability to identify the RFID tag and the necessary information (physical/virtual location), while the application software is responsible for the ID information and related detection conditions. Use it properly. Just like any other technology, it has to be combined with other integrated solutions to make sense. Therefore, special consideration must be given to the management of the changed program in order to have the best results. In recent years, RFID technology has had some significant progress and many successful cases. Although this technology can be applied to peer-to-peer tracking and visibility, it has not had a major impact on the logistics industry, as the technology applied in this industry is approaching maturity. Although the cost factor will gradually decline according to the supply demand law; mutual interoperability will also be established by various global standards organizations, but more importantly, business model changes, government policies and social acceptance can achieve globalization tracking. And identification. These non-related information technology problems are quite complicated. These are issues outside the information technology field and the biggest crux of the whole problem. Prior to this, RFID technology will continue to the current development direction, successfully achieved in a limited application and some close cooperation, information exchange can be well controlled. Since 2006, Cyberport, a high-end and intelligent intelligent office building in Hong Kong, has been using RFID+3G facility management solutions developed by E-Commerce Solutions (EBSL). EBSL also assisted the general plan of the University of Hong Kong in early 2009, introducing RFID to more than 1 million books, allowing students to borrow and return books on their own, and eliminating the cumbersome rental and inventory problems of the library, thus providing more service.

In addition, there are a number of retail RFID application cases, including the Schmidt Electronics Group Smart Retail System (SRS) and mirrors installed at the Mei Enyi Fashion Boutique, which can be used to provide more information on clothing matching to savvy buyers; It is electric power logistics. The logistics solution from PCCW has actually introduced the RFID sales management system to a leading home appliance and lighting company, which not only enables customers to have a simple order management model, but also improves operational efficiency and improves customers. Satisfaction. PCCW and Nuance-Watson's Mobile Discovery Kiosk and EBSL's Grand Buy Department Store E-Sample SoluTIon are smart sales/marketing automation services that help businesses improve Their sales or marketing capabilities. The GS1 Hong Kong has just launched the ezTRACK standard as the basis for the information exchange platform to provide consumers with a complete supply chain information query and confirmation.

The Hong Kong government has been very supportive of RFID application research. Established in 2006, the Hong Kong Logistics and Supply Chain Management Application Technology Research and Development Center (LSCM) was established with a focus on RFID-related applications in logistics and supply chain management. The development of ET I's RAE Middle ware was sponsored by the LSCM Foundation and commercialized by EBSL.

Food safety is relevant to every citizen, not only a global issue, but also a priority for governments. In Hong Kong, most of them import food from the Mainland, and both governments have invested in many measures to ensure the quality of food supply. Since 2008, the University of Hong Kong Institute of Electronic Business Technology (ETI) has been working with the Shenzhen Entry-Exit Inspection and Quarantine Bureau (SZ CIQ) and the Entry-Exit Inspection and Quarantine Bureau (GD CIQ) in Dongguan to establish a management system from Guangdong/Shenzhen. Vegetable and hog food safety information platform shipped to Hong Kong. CIQ will collect and use this information to improve sound internal management to expedite transit inspection and customs clearance procedures; ETI will provide food safety related services, from inquiries regarding order-related shipping information, to packaging vegetables and merchandise that supermarket customers want to purchase. service. It will also provide a message feedback mechanism that will allow users to respond to food safety anomalies.

This plan is very important because it will develop ways to extract and collect information from farms, vegetable distribution centers, food processing centers and logistics carriers, and understand how effective RFID technology is in the process. Including the release object of the data and the way it is used, this is an important key to the completion of the plan. The value of the system is unquestionable, but whether the method is feasible, cost-effective and acceptable to the government and the industry is the most important issue of this plan. Although the program initially focused only on vegetables and pigs from Guangdong/Shenzhen to Hong Kong, it can be extended to any food in all provinces of China and other countries. Once the food safety inquiry and tracking proves to be successful, it will be scalable to integrate with other sensing technologies to provide food quality management services to the industry, which is the next phase in 2010. RFID technology has come a long way, basically it is a proven low-cost technology that can be effectively used in many tracking solutions. I believe that it will be widely used in the next five years.

RFID directly inherits the concept of radar and has developed a new AIDC technology called RFID technology. Harry in 1948. Stokeman's "Communication with Reflected Power" laid the theoretical foundation for RFID.

Application in animal husbandry

1. Install an electronic ID card for cattle

The first step in RFID-based cattle farming and tracking is to install an electronic ID card on the cow to create a permanent digital file for each cow that uniquely identifies each cow's attributes. The basic methods for installing electronic labels in animals include: collar, ear tag, injectable and pill electronic tags.

2. RFID-based cattle farm management system

Write livestock information into the chip, including: animal owner - owner name, gender, livestock, characteristics, immunity, vaccine type, manufacturer, production batch number, inoculation method, inoculation dose, immunization amount, and immunization name The owner needs a handheld data collector and can obtain information about the livestock. According to the regulations of the Ministry of Agriculture of China, the coding format of the cattle is: 2-×××××× (county-level administrative area code)-×××××××× (identification sequence number). Other countries should be modified according to the local number. The specific operation process is: in the daily management of animal husbandry, the animal owner only needs to carry a wireless handheld terminal to read the animal ear tag to be followed, and the relevant information of the animal can be displayed on the hand-held terminal. The owner can feel this information to deal with his daily diet, medical history, birth history, and immune records. Quick and easy, saving a lot of time. It is not necessary to look up the original acquisition for the archival card. At the same time, the livestock file can be created in the background computer after the data transmission. Record the details of each animal through a computer professional. Don't worry about ambiguous records or lost file cards. At the same time, the department and relevant leaders can instantly check the status of any pasture, bar and livestock through the network to achieve information transparency. 3 RFID-based dairy cow precision feeding subsystem

The micro-culture digitalization is based on the database system. In the distributed network environment, the data acquisition and update, the data storage and management, the information extraction and analysis of each business unit user are realized, and the basic data is formed through the digital agricultural basic data warehouse mechanism. Sharing and information mining. The knowledge and experience of fine farming experts are abstracted, data models are established to guide dairy farming, and the model is adjusted using feedback generated in farming practices. The logical structure of the cow digital farming system is divided into three layers: data layer, service layer and application layer. The data layer consists of a database of digital agricultural basic data warehouses (including meta-databases, image databases, integrated feed nutrient databases), sensor information bases (including wireless RF sensor data, video surveillance data, etc.), and expert model libraries. The service layer is composed of a digital agricultural fine breeding support platform and an information sharing and exchange platform, including a computer network system, a communication system, a monitoring system, a display system, and an operating system. The application layer mainly includes various application systems, and calls the database server information and services as a client. 4 RFID-based meat tracking system
