OPEN-TYPE RFID ENTRANCE GUARD SYSTEM FOR ACCESS DETECTION AND HANDLING METHOD THEREFOR

摘要

Disclosed are an open-type RFID entrance guard system for access detection and a handling method therefor. The system mainly comprises an RFID reader, an antenna, a tag and a background server. The operating method thereof is: respectively deploying two antennas having a certain angle included therebetween inside a device at both sides of an entrance guard channel, both of which are connected to the RFID reader, wherein the antenna receives a signal reflected by an RFID tag carried by an object accessing the entrance guard, and time periods during which the antennas at both ends of the entrance guard receive the reflected signal are different, and by using such a characteristic, determining and recording and displaying entering and exiting behaviours of personnel in the entrance guard system in real time. The present invention applies RFID technology to an open-type entrance guard system, which can automatically recognize entering and exiting behaviours when a person accesses the entrance guard, without the need for arranging a wing gate or contact-type recognition, thereby greatly improving the efficiency of entrance guard access of personnel.
