RFID Applications in the Construction Industry

RFID (Radio Frequency Identification) technology is a technology that transmits and reads data through radio signals. It is widely used in logistics management, inventory management, vehicle management, anti-counterfeiting and traceability. However, since metal has the characteristics of mutual interference and absorption with radio signals, there are some problems when using RFID technology in a metal environment. To address this problem, RTEC has launched an anti-metal tag. This article will explain the principle, function, characteristics and application scenarios of the anti-metal tag.

1. The principle of RFIDanti metal tag

The principle of RFID technology is to generate a high-frequency electric field through an antenna. When the signal sent by the reader encounters the antenna on the tag, an induced current will be generated. The frequency of the induced current is the same as the frequency of the received high-frequency signal. After the chip in the tag receives the induced current, it generates electrical energy, activates the circuit inside the chip, reads data from the storage area and transmits it back to the reader. However, when the tag is placed on a metal surface, the radio waves reflected by the metal surface will interfere with the radio waves received by the tag, which will affect the reading distance and accuracy of the tag, or even fail to read.

To solve this problem, RTEC launched a RFID anti metal tag. The anti metal RFID tag optimizes the antenna structure, and by reducing the size of the antenna and changing the shape of the antenna, the tag is closer to the state of a half-wavelength antenna, thereby reducing the interference of reflected waves. In addition, the anti-metal tag can further reduce the impact of reflected waves on tag reading and writing by setting multiple antennas and adding buffers.

2. Functions of anti metal tag

Anti-interference: anti metal tag can eliminate the interference of metal surfaces on tag operation and improve the recognition rate and reliability of tags.

Long-distance reading: Compared with ordinary tags, uhf metal tag can maintain a longer recognition distance on metal surfaces.

Stability: Due to the influence of metal surfaces on tag reading, ordinary tags may have inconsistent reading effects in different environments, while on metal RFID tags have more stable and reliable reading and writing capabilities on metal surfaces.

3. Features of on metal RFIDtags:

Waterproof and wear-resistant: Since on metal RFID tags are mainly used in logistics, inventory management and other fields, they are often exposed to water, collision, friction and other scenes, so anti-metal tags usually have good waterproof, anti-collision and durability.

Applicable to metal surfaces: Compared with ordinary tags, anti-metal tags can better adapt to the use environment of metal surfaces, can read tag data faster on metal surfaces, and are very helpful for managing items such as steel coils and machine parts.

Reusability: uhf metal tag can usually be read and written multiple times, and can be used multiple times during the life cycle of the item, thereby improving efficiency and reducing costs.

4. Application scenarios of anti-metal tags:

Logistics management: In the logistics process, items often need to be loaded in metal boxes or metal shelves. The use of uhf metal tag can more stably identify item information and effectively improve the efficiency of logistics.

Vehicle management: In the field of vehicle management, it is usually necessary to install tags on vehicles to track and manage vehicle information. However, vehicles usually have metal surfaces. On metal RFID tags can better adapt to the metal surfaces on vehicles and improve the reading efficiency and accuracy of tags.

Parts management: In the fields of automobiles, aviation, electricity, etc., RFID tags metal are often used to track and manage various parts, which can improve the efficiency of parts tracking and inventory management.

Factory production equipment management: In industrial scenarios, anti-metal tags can be used to manage the operating status, maintenance records and other information of equipment, which can improve the accuracy and efficiency of equipment management.

Logistics distribution: In the field of logistics, RFID tags metal can track the location, transportation routes and other information of goods, and improve the accuracy and efficiency of logistics distribution.

Identification management of hazardous places such as oil and water: Because metal mountted RFID tags have waterproof, anti-collision and durable characteristics, they can be used for identification management in hazardous places such as oil and water, which can improve the safety and efficiency of the workplace.

RFID anti metal tag is an important part of RFID technology. With their long identification distance and strong anti-interference ability, they have been widely used in logistics, vehicle management, dynamic leasing and other fields. In the future, with the development of the Internet and the Internet of Things and the popularization of intelligence, RFID anti metal tag will have wider application scenarios and greater market demand.
