Background & Application
As an advanced wireless communication technology, RFID is used in vehicle management, smart parking, vehicle repair and maintenance and other fields with characteristics of non-contact, long-distance, fast identification and data storage, and it shows great potential and advantages in the above fields.
With the development of science and technology and the acceleration of urbanization, traditional vehicle identification methods are increasingly showing problems such as low efficiency and poor accuracy. The emergence of RFID technology provides new possibilities for solving these problems. Therefore, it has been further applied in automatic vehicle identification.
Application Cases
In an age of continuous develop of economy and fast pace of life, people increasingly choose cars as their means of transportation. An RFID label is attached to the car windshield to store the vehicle's unique identification information. RFID technology is used in some parking lots, highways and other areas can realize automatic identification of vehicles, automatic entry and exit management, and parking space management, which improves traffic efficiency and reduces Human intervention. Many states in the United States have adopted RFID reading and writing technology. For example, some car owners in Florida attached RFID stickers to their windshields to pay without stopping.
In many automobile assembly workshops, RFID smart label is used to track vehicle assembly processes and inspections, in and out of warehouses, and to manage auto parts. Each part, parts box, or component is affixed with an RFID label, which contains its unique identification and related production information. RFID readers are installed at key nodes of the production line and it can automatically identify these labels and confirm the specifications, batches and quality status of parts. If parts that do not meet requirements are found, the system will immediately send out an alert to ensure product quality and the accuracy of the production process. There are also some auto repair shops that use RFID labels to store vehicle repair history and maintenance information, manage spare parts, monitor repair processes, etc. during vehicle repair and service. So the service stations can quickly obtain vehicle data and improve repair efficiency and service quality.
RFID technology is applied in automatic vehicle identification to realize automatic identification and tracking improving the efficiency and accuracy of vehicle management also effectively improves the intelligent level of traffic management and the service quality of the service platform for car owners.
Advantages of RFID in Automatic Vehicle Identification
1.Contactless and Remote Reading
RFID tags are not susceptible to contamination, wear or obstruction, and have the advantages of non-contact, long distance, high speed, large capacity, and anti-interference, allowing the automatic vehicle identification system to have higher accuracy and stability.
2. Reduce Costs and Improve Efficiency
By reducing manual operations, shortening identification time and optimizing resource allocation, RFID technology can reduce operating costs and improve overall work efficiency and service quality.
3. Flexibility and Scalability
The RFID system can be flexibly configured and expanded according to specific needs, adapting to various vehicle identification and management application scenarios.
In general, RFID technology provides an efficient, accurate and convenient solution for automatic vehicle identification. It is believed that through further research and development, it is expected to promote technological innovation and industrial upgrading in vehicle management, traffic monitoring, smart parking and other related fields.
Analysis of Product Selection
In vehicle identification applications, when selecting the surface material, chip, antenna and adhesive material of the RFID electronic tag, the following factors should be considered:
1. Surface material: the appropriate surface material is selected based on actual application scenarios (such as climate conditions, attachment location, life expectancy, etc.) to ensure the reliability and reading performance of the tag during the vehicle life cycle. You can choose materials such as PP synthetic paper, PET which have good physical strength and chemical stability.
2.Chip: Ultra-high frequency (UHF) chips are often used in vehicle entry and exit management, highway toll collection and other occasions. There must be enough storage space to save the vehicle's unique identifier (such as VIN code) and other necessary data. In order to ensure the security of vehicle information, the selected chip should also have advanced data encryption and anti-tampering capabilities, such as the Alien Higgs series of chips.
3.Antenna: the antenna used in vehicle identification must cooperate well with the chip and have a large metal coverage area to ensure signal transmission efficiency. At the same time, the antenna structure should be able to adapt to the vehicle installation environment. such as embedded or attached design, it requires antenna material and design are able to maintain stable electrical performance under various climatic conditions.
4. Adhesive material: use high-strength, long-lasting adhesive material to ensure that the label is firmly affixed to the designated location during the entire life cycle of the vehicle and will not fall off due to vibration, temperature changes, etc.; the adhesive material must be consistent with the surface material and vehicle surface. The materials are compatible and will not cause chemical reactions or damage the original car paint; it should have excellent dustproof, waterproof, heat-resistant, cold-resistant, moisture-resistant and aging-resistant properties to adapt to the harsh usage environment of the automotive industry. Normally we use a strong adhesive - oil glue.
Based on the above requirements, RFID tags used in vehicle identification should have high performance, high dielectric constant, high reliability, strong weather resistance and excellent sticking stability, so as to meet the long-term and efficient operation requirements of the vehicle identification system.
