- The integrated reader is mainly used for controlling the identity of vehicles, personnel entry and exit, industrial production line material identification, etc.; Fixed readers are commonly used in warehouse logistics, supply chain environment material inventory, inbound and outbound management, clothing, shoes and hats, jewelry retail department stores, and management from factories to terminal retail stores.
Ⅰ、 What is the difference between an all-in-one machine and a split machine?
1.1 Advantages of integrated readers and writers:
1. The antenna and reader are integrated into a closed wall, with a working protection level of IP67, suitable for outdoor use;
2. Due to the use of metal material on the back cover wall of the reader, it is easy for the reader to dissipate heat and is conducive to long-term outdoor work;
3. The wiring of the reader/writer interface is simple, mainly for power and communication lines, making it very suitable for rapid deployment;
4. Integrated read-write device manufacturer accessories are easy to install, and non professionals can also carry out construction;
5. Integrated readers have a high cost performance ratio and are relatively inexpensive;
Application field:
1. The integrated reader is mainly used for controlling the identity of vehicles, personnel entry and exit, industrial production line material identification, etc., in non intensive situations that require a large number of label readings;
2. The reading distance of the integrated reader can be selected based on the usage scenario, which requires different gain sizes and irradiation angles of the integrated reader according to the reading distance and antenna irradiation angle;
Ⅱ、 Advantages of fixed readers and writers:
Fixed RFID readers, also known as split type RFID readers, have their reading and writing parts arranged separately from the RFID antenna, and their RF signals are connected through coaxial cables.
1. The control circuit and radio frequency circuit of a fixed RFID reader/writer are relatively complex, and high performance indicators are required for the reader/writer, especially in technologies such as radio frequency interference cancellation and multi tag reading anti-collision algorithms;
2. The RF output power of the fixed RFID reader can reach 30-33dBm, and its performance in reading distance and reading multiple tags is better than that of the integrated RFID reader;
3. The fixed RFID reader has more diverse functions, with more options for GPIO interfaces, communication interfaces, etc., making it easier to achieve project system integration and use;
4. The outdoor installation of the fixed reader/writer host requires a waterproof outer box, and the operation between the reader/writer and the antenna needs to be connected by a high-quality coaxial feeder to ensure its long-term stable operation;
5. Fixed readers have a wider range of application scenarios and can handle more complex work environments, such as; Require fast labeling, extensive inventory, long distance, and fast speed;
Application field:
Fixed readers are commonly used in warehouse logistics, supply chain environment material inventory, inbound and outbound management, clothing, shoes and hats, jewelry retail department stores, and management from factories to terminal retail stores; It is also commonly used for anti-counterfeiting traceability, book and archive management, etc.
