Abstract:
PURPOSE: A dynamic channel management and time synchronization in a fast active RFID(Radio Frequency ID) system are provided to flexibly use channels and smoothly perform communication between a reader and a tag without an influence of disturbance. CONSTITUTION: A reader selects one of channels and transmits a tag wakeup signal, a low frequency communication signal including selected channel information and termination signal, and a high frequency communication signal for collecting tag information(130). A tag becomes a wakeup state according to a wakeup signal of the low frequency communication signal while performing wireless communication with the reader and synchronized with the selected channel in time according to the channel information(140). The tag maintains a state for receiving the high frequency communication signal for a predetermined time according to the termination signal and transmits the tag information(160).

Abstract:
PURPOSE: An intelligent access managing system which uses an RFID(Radio Frequency Identification) is provided to recognize the passing of an access gate without any special action of an accessor, thereby automatically performing access management. CONSTITUTION: The first receiving unit(20A) receives an RF signal from an RFID unit in the first recognition domain. The second receiving unit(20B) receives a wireless signal from an RFID unit in the second recognition domain placed after the first recognition domain. A system control unit(30) calculates the number of passing people through the recognition of information sent with an RF signal received by the first receiving unit and performs access authentication through the recognition of information sent with RF signal received by the second receiving unit. The system control unit records the management of diligence and laziness based on the number of the people and the access authentication.
