A kind of equipment automatic identification device and automatic identification method based on RFID technology

Abstract

The invention discloses an equipment automatic identification apparatus and method based on RFID. The equipment automatic identification apparatus comprises a controller, a low-frequency exciter, a radio frequency receiver, a display terminal, and a semi-active radio frequency electronic tag, wherein the low-frequency exciter, the radio frequency receiver, and the display terminal are electrically connected with the controller, and the semi-active radio frequency electronic tag adheres to equipment required to be identified. The equipment automatic identification apparatus and method based on RFID may automatically identify a plenty of targets in a noncontact way. The semi-active radio frequency electronic tag has a long service life. The operation of the low-frequency exciter and the radio frequency receiver can be remotely controlled and an electronic tag can be automatically scanned.

Description

technical field [0001] The invention relates to the technical research field of the Internet of Things, in particular to an automatic equipment identification device and an automatic identification method based on RFID technology. Background technique [0002] Radio Frequency Identification (RFID) technology is a non-contact automatic identification technology realized by radio frequency communication. RFID technology was first used in the Second World War for aircraft target identification, but due to technical and cost reasons, it has not been widely used. Since the 1960s, the theory of RFID technology has developed rapidly, and various RFID technologies and applications have emerged rapidly; in recent years, with the development of technologies such as sensor networks, large-scale integrated circuits, network communications, and information security, RFID technology has also been It is widely used in many fields such as railway car number identification, ID card and tick...
