IDENTIFICATION SYSTEM FOR HUMAN-MACHINE INTERFACE USING RADIO FREQUENCY AND IDENTIFICATION METHOD FOR THE SAME

摘要

An identification method for a human-machine interface using radio frequency and an identification system using the method is disclosed. First, a computer senses a radio frequency identification (RFID) tag and compiles a password table according to tag number of the RFID tag. The computer downloads the password table to a human-machine interface (HMI) as the compilation completed. When the human-machine interface executes identification process, the HMI senses the RFID tag via a radio frequency card reader and looks up in the downloaded password table if any tag number matches with the sensed RFID tag is recorded. If yes, HMI uses the identification password corresponding to the tad number in the password table for executing identification process.
