DATA INTERACTION METHOD BASED ON NEAR FIELD COMMUNICATION

WIPO Patent Application WO/2024/031995

A1

A data interaction method based on near field communication, comprising: an initiator sends a data block transmission request instruction; a receiver receives and analyzes the instruction, and returns a confirmation instruction to the initiator; the initiator sends a starting information data packet; the receiver receives and stores content of the data packet, and returns a confirmation instruction; the initiator continuously sends multiple frames of data packets; the receiver receives the data packets, and verifies and stores the data packets; the receiver sends a transmission supplementation application; the initiator supplementarily sends a data packet according to the transmission supplementation application, and after multiple rounds of interaction, the receiver determines that all data reception is completed, and sends a transmission stop instruction to the initiator. The present invention reduces the time taken by data interaction, improves transmission efficiency, uses a fault-tolerant transmission supplementation mechanism so as to ensure the integrity of data, and is particularly suitable for data communication under the conditions that the wireless network environment is complex and interference is present.
