DATA TRANSMISSION METHOD AND DEVICE THEREOF - A simplified explanation of the abstract
This abstract first appeared for US patent application 18457307 titled 'DATA TRANSMISSION METHOD AND DEVICE THEREOF
Simplified Explanation
The patent application describes a method and device for tag access in data transmission. Here is a simplified explanation of the abstract:
- The method involves an answer device receiving signaling from a read/write device, which carries target flag information.
- The target flag information helps determine the specific answer device to be accessed.
- The answer device has its own first flag information that matches the target flag information.
- The answer device then determines a first slot and sends first access information to the read/write device in that slot.
- This method helps avoid collisions between different slots in the next round, reducing collision probability and improving tag access efficiency.
Potential applications of this technology:
- This technology can be applied in various industries that use RFID (Radio Frequency Identification) systems, such as retail, logistics, and healthcare.
- It can be used for efficient inventory management, tracking and tracing of goods, and authentication purposes.
Problems solved by this technology:
- The method helps prevent collisions between different slots during tag access, which can occur in RFID systems with multiple tags and devices.
- It improves the efficiency of tag access by reducing collision probability and ensuring smooth data transmission.
Benefits of this technology:
- Improved tag access efficiency leads to faster and more accurate data transmission in RFID systems.
- The method helps optimize the use of slots, reducing collision probability and improving overall system performance.
- It enhances the reliability and effectiveness of tag access, ensuring seamless communication between read/write devices and answer devices.
Original Abstract Submitted
A data transmission method and a device thereof are provided for tag access. The provided method includes: An answer device receives first signaling sent by a read/write device. The first signaling carries target flag information. The target flag information is used to determine the answer device. First flag information of the answer device matches the target flag information. The answer device determines a first slot, and sends first access information to the read/write device in the first slot. In the provided method, the first slot is determined, to avoid collision of different slots in a same slot in a next round, reduce a collision probability, and improve tag access efficiency.
