NFC-based multi-parameter wrist vital sign data communication method

Abstract

The invention discloses a multi-parameter wrist vital sign data communication method based on NFC. In step 1, the core processing module packs multi-parameter wrist vital sign data into data frames to obtain heterogeneous data packets; in step 2, the core processing The module encrypts the heterogeneous data packet and writes it into the NFC module; Step 3, the NFC reading terminal obtains the communication data by reading the NFC module; Step 4, the NFC reading terminal verifies the communication data after decryption, if the verification result If the communication data is a heterogeneous data packet, upload the heterogeneous data packet to the host computer; otherwise, discard the communication data and return to step 3 to read again until the encrypted heterogeneous data packet is obtained. Beneficial effects: NFC transmission is used to enhance transmission efficiency. Since NFC requires near-field reading to complete data transmission, it can adapt to occasions with strong electromagnetic interference, and it can be read only after being close to it, which can prevent information from being used by strangers. Privacy is guaranteed.

Description

technical field [0001] The invention relates to the technical field of portable sign detection equipment, in particular to an NFC-based multi-parameter wrist vital sign data communication method. Background technique [0002] In recent years, with the advancement of electronic technology and the rapid development of wireless communication technology, wearable devices have received more and more attention in people's daily life, especially in the field of wearable medical devices. The so-called wearable medical device refers to embedding sensor, wireless communication, multimedia and other technologies into people's daily wear such as glasses, watches, bracelets, clothing and footwear, and can measure various signs by wearing it close to the body surface. [0003] At present, most wearable devices have single functions and use a single sensor to detect a single parameter, which cannot meet the requirements of high integration and multi-functional detection; and most of them u...

AI Technical Summary

Problems solved by technology

[0003] At present, most wearable devices have single functions and use a single sensor to detect a single parameter, which cannot meet the requirements of high integration and multi-functional detection; and most of them use Bluetooth and WIFI wireless communication methods for data transmission. Although the transmission rate is fast, it cannot Adapt to occasions with strong electromagnetic interference, the accuracy and stability of data transmission cannot be guaranteed in the environment of strong electromagnetic interference

[0004] There is no special data format specification and transmission management method for the collected vital sign parameters, which can easily cause loss of useful data and wrong reception, wasting the collected data resources
