PURPOSE: A safety management apparatus using RFID in a construction field is provided to grasp whether a worker of a field hooks a safety ring in a safety device, thereby preventing a falling accident due to warning generation. CONSTITUTION: A sub RFID tag(400) is installed in a safety ring. If a sensing signal is inputted to a processor(460) of the sub RFID tag, a processor outputs an ID stored in an ID storage unit(470). A main RFID tag(100) is worn in the body of a worker. The main RFID tag transmits the ID to an RFID reader(200). |
