Data transmission method, device and near-field communication device based on near-field communication

Abstract

An embodiment of the present invention provides a near-field communication-based data transmission method, device, and near-field communication device. The method includes: the NFC touch device sends an intelligent extraction command to the first NFC device to trigger the first NFC device to send the first The data to be transmitted determined by the NFC device is intelligently extracted and processed to obtain the intelligently extracted data; the NFC touch device receives the intelligently extracted data sent by the first NFC device through NFC communication; the NFC touch device sends the intelligently extracted data to the second NFC device through NFC communication . During the transmission process, the size of the NFC touch device is smaller than the size of the first NFC device and the second NFC device, so that the NFC antenna of the NFC touch device, the NFC antenna of the first NFC device, and the NFC antenna of the second NFC device are easily in the same position. Within the effective communication range, the success rate of NFC communication is improved, and at the same time, the limitation that two NFC devices must be within the effective communication range to perform NFC communication is avoided.

Description

technical field [0001] The embodiments of the present invention relate to the communication field, and in particular, to a data transmission method and device based on near field communication, and near field communication equipment. Background technique [0002] Near Field Communication (NFC) is a short-range wireless connection technology based on Radio Frequency Identification Devices (RFID). It works at a frequency of 13.56MHZ and currently supports 106Kbit / s, 212Kbit / s, and 424Kbit / s or 848Kbit / s four transmission rates, the effective range of communication is 0~20cm, the typical value is 4cm. [0003] NFC is more suitable for a small amount of data transmission due to its simple operation and low data transmission rate. For example, share business cards or contact information, share webpages, complete Bluetooth or Wi-Fi pairing, etc. through NFC technology. Usually, two NFC-enabled devices (hereinafter referred to as NFC devices) perform NFC communication in a back-...

AI Technical Summary

Problems solved by technology

[0004] However, with the diversification of near-field communication devices, such as mobile phones, tablets, computers and even various home appliances, the size of NFC devices gradually varies, and users may not be very clear about the specific area of ​​the NFC antenna of the NFC device. , while the effective range of NFC communication is limited

Therefore, in the process of placing two NFC devices back-to-back, the user may need to go through many trials to successfully basically align the NFC antennas of the two NFC devices, resulting in a decrease in the success rate of NFC communication, and this back-to-back transmission method is also Bring a certain sense of discomfort to the user, thus greatly reducing the user experience
