Abstract

The invention provides a human-machine interface (NFC) device having a near field communication (NFC) function. The human-machine interface device comprises an NFC antenna for receiving a radio-frequency signal from an external NFC device and sending the radio-frequency signal from an NFC transceiver to the external NFC device, the NFC transceiver for decoding the radio-frequency signal from the NFC antenna and sending decoded data to an HMI processor and modulating the data from the HMI processor so as to generate the radio-frequency signal to be sent through the NFC antenna, the HMI processor utilizing a serial communication interface to be communicated with the NFC transceiver and executing interactive operation between the external NFC device and the HMI processor according to the data from the NFC transceiver.

Description

technical field [0001] The present invention relates to a human-machine interface device, and more specifically, to a human-machine interface (HMI, human machine interface) device with near field communication (NFC, near field communication). Background technique [0002] NFC is a short-distance non-contact communication method, which combines non-contact induction (RFID) and wireless connection technology, and acts on the 13.56Mhz frequency band. [0003] So far, NFC has not been used in industrial HMIs. [0004] For industrial HMI products, some functions seem to be inconvenient and friendly to users, for example, data access, password setting, system update, application installation, product information tracking, remote maintenance, etc. [0005] When combining HMI with NFC, it will provide users with many new, intuitive and beneficial experiences about the product. [0006] 1>Existing remote HMI [0007] a. Using WiFi (Wireless Fidelity Technology) as the communica...
