It significantly improves efficiency and accuracy while enabling real-time visibility of materials, thereby providing robust support for faster and more reliable firefighting rescue operations.
1. Overview of RFID Technology
1.1 Composition and Working Principle of an RFID System
RFID technology primarily consists of tags, readers, and antennas. RFID tags are carriers of item information and are categorized into active and passive tags. Active tags have a built-in battery and can actively transmit signals, offering a longer read range. Passive tags derive energy from the RF signal emitted by the reader, resulting in a relatively shorter read range. RFID readers are used to read information stored on tags and transmit it to a backend management system. RFID antennas are responsible for transmitting RF signals between the tag and the reader.
When a tagged item enters the RF field of an RFID reader, the tag receives the RF signal from the reader via its antenna. It uses the energy from this signal to send the information stored in its chip back to the reader. Upon receiving the tag’s return signal, the reader decodes and processes it, then transmits it to the backend management system for further analysis and management.
1.2 Advantages of RFID Technology
- Non-contact Identification: RFID technology enables identification without direct physical contact, avoiding the need to align items as required by traditional barcode scanning, thus improving identification efficiency.
- Long-distance Identification: The read range of RFID tags can reach several meters or even tens of meters, allowing long-distance identification of items and facilitating material management over larger areas.
- Rapid Data Exchange: RFID technology can read a large volume of tag information and perform rapid data exchange in a short time, significantly improving material management efficiency.
- Reusability: RFID tags can be reused, reducing costs. In contrast, traditional barcode labels typically need replacement after a single use, increasing management costs.
- Large Data Storage Capacity: RFID tags can store substantial information, including item name, model, production date, usage records, etc., providing rich data support for material management.
