The Application Status of RFID in Intelligent Security

As one of the key technologies of security and Internet of Things, RFID is currently rich in related products and solutions, and the market application is gradually deepening. The application fields are expanding and expanding, especially in intelligent transportation, smart parking, smart access control, radio frequency security, personnel and Areas such as item positioning and track management have gradually gained very mature applications.
Taking jewelry management as an example, the jewelry industry has problems in the exclusive counters of specialty stores. The products that the jewelry industry sells every day are high-value jewellery, which is very important for the daily inventory of goods.

However, the current work of jewellery inventory is basically done by manual manual operation, and the jewellery products have the small size and large number of actual situations. A large number of products are counted by a small number of sales personnel, which results in a huge actual situation of inventory work time.

After adopting the RFID scheme, the target object can be automatically identified by the RFID handheld terminal, and the identification work no longer requires manual intervention. RFID jewelry management is to attach RFID tags to precious jewelry products. Combined with the jewelry counting equipment(fixed RFID reader) installed on the counter, it is used to monitor, control and track the labeling of jewelry accessories, enabling fast inventory and real-time management functions.

In addition to convenience, RFID products have high stability, no mechanical wear and long service life, so the maintenance cost is relatively low. This is an important reason for domestic users to accept and innovate the new RFID technology.

How to Read the Data of UHF RFID Large Capacity User Area

When using the existing RFID Demo software, the length of the read operation cannot exceed 255 words, which is 510 bytes. This is also the upper limit of the amount of data read by Gen2. Reading too much data at a time will also cause the performance of the reading to be unstable. In fact, reading 128 words at a time is not stable. This is related to the performance of the specific label. When actually doing the project, it should be sufficient. After testing, choose an appropriate value as the number of single reads and writes.

There are a lot of UHF RFID tags in the user area, such as 1K bytes, how to read the large-capacity data area? There are two ways to read 1K bytes of data as an example:

Call the readWait SYNC API 4 times, reading 128 words each time;

ReadWait offset=0, size=128 words;

ReadWait offset=128, size=128 words;

ReadWait offset=256, size=128 words;

ReadWait offset=384, size=128 words;

Call the “Actions.TagAccess.Operation Sequence.performSequence” ASYNC API multiple times (recommended this way - good performance)

If 128 words is unstable, you can read 64 words, 32 words or less each time, and the number of calls increases accordingly. The read and write performance of different UHF RFID reader is different. According to the actual test, the amount of read and write data of a single sequence is adjusted; the number of calls is increased accordingly.

Application of RFID Identification Technology in Vehicle Automatic Counting System

By putting the license plate number of the transport vehicle into the RFID electronic tag, when the transport vehicle enters various transport nodes such as intersections, unloading yards, yards, warehouses, etc., it can be carried out by an RFID card reader installed above the road. Reading, completely out of manual intervention, improves the speed and accuracy of vehicle traffic counting.

Compared with the license plate recognition technology of video and image processing, RFID-based vehicle recognition has high accuracy and is not easily affected by the environment, and can accurately and comprehensively acquire vehicle information.

The electronic tag is pre-written with the basic information of the vehicle through the card issuing management system, such as the vehicle ID, the license plate number, the owner, the fleet, and the like. The RFID tags are installed on the vehicle windshield of all the entrances and exits, and the vehicle has a unique ID card. The UHF RFID antenna system is installed at all intersections, roads, etc. where it is necessary to identify the electronic license plate.

Electronic license plate (R F I D tag) The passive card in the U H F (902 ~ 928MHz) frequency band can be used for long-term maintenance and repeated use. The electronic license plate is mounted on the front windshield of the vehicle by anti-disassembly technology, which forms a unique correspondence with the vehicle and becomes the only electronic identity mark of the vehicle. The identity information of the vehicle is strictly fixed in the vehicle.

The RFID electronic license plate automatic counting system does not require manual invoices, which greatly improves the accuracy of counting, reduces the error of counting people, and prevents human cheating. The system can realize bicycle statistics and group statistics, settlement statistics, and engineering materials management.

What is the Difference Between HF and UHF RFID Technology

From the perspective of technological development, high-frequency technology is relatively mature than UHF technology. Through continuous improvement and improvement, a learning curve model for high-frequency tag production, data protocol sharing, and the basis for constructing RFID applications has also been established.

Both high frequency and ultra high frequency RFID systems rely heavily on the communication environment between the RFID reader and the tag. UHF uses the principle of electromagnetic emission and is therefore more susceptible to electromagnetic interference. At the same time, the metal will reflect the signal, and the water will absorb the signal, all of which will interfere with the normal function of the tag.

The International Organization for Standardization/International Electrotechnical Commission established the ISO/IEC, 15693 standard in 1999 to regulate the implementation of high frequency radio frequency identification technology. The standards for UHF are not so uniform, and the frequencies used in different countries are not the same. The UHF designated by the EU is 865~868MHz, the United States is 902~928MHz, India is 865~867MHz, Australia is 920~926MHz, Japan is 952~954MHz.

The European Telecommunications Standards Institute (ETSI) EN300-220 specification has two main provisions that are less favorable for UHF. One is about the power limitation, which stipulates that the effective radiated power is 500 mW; the second is about the bandwidth limitation, and as a result, the reader cannot be frequency hopped.

RFID tags have received a lot of praise from users in practical applications. Although the price is relatively high, UHF RFID technology has obvious unique advantages in automatic identification and security of products, and the production efficiency and management of enterprises will be has seen an increase.

RFID Implements Tire Pressure Monitoring and Security Anti-theft System

Radio Frequency Identification (RFID) is a non-contact, automatic identification technology. The car security anti-theft system uses radio frequency identification technology to automatically identify the target object and obtain relevant data through the radio frequency signal. RFID technology uses RF transmission to read chip data through external materials for non-contact operation.

Communication data uses an encryption algorithm to encrypt data for secure data storage, management, and communication. With the rapid development of electronic technology, the integration of electronic chips has increased, and the cost of RFID systems has been continuously reduced, accelerating the promotion and application of intelligence in the automotive electronics industry.

Taking a four-tire car as an example, the system consists of four tire modules, one RFID reader module and one base station module. The base station module includes an RF receiver, an LF transceiver, a central control part, a human-machine interface, and is used for transmission. Ignition, gated command of the Automotive Area Interconnect Network (LIN) bus.

The four tire modules are installed in the four tires of the car, and the pressure, temperature and battery voltage parameters of each tire are measured in real time, and the measured data is sent to the base station module for processing by RF communication. The base station module receives RF data from the tire module on the one hand, and further determines whether the tire parameters are normal, and performs real-time alarm if an abnormality is found.

The RFID security-based anti-theft system greatly improves the flexibility and security of the system, saves system space, and reduces production costs. It has broad application prospects in the automotive electronics field.
