RFID TAG UNIT DEVICE, RFID TAG UNIT SYSTEM WITH THE DEVICE, AND THE METHOD FOR CONTROLLING THE SYSTEM

摘要

PURPOSE: A tag unit device, a tag unit system with the device, and a method for controlling the system are provided to minimize initial installation costs and operating costs. CONSTITUTION: A signal processing unit(350) of a unit control block(300) converts voice information obtained by a unit input unit. A unit controller(310) electrically communicates with the signal processing unit. A unit antenna(330) transceives data with a unit tag(20). A unit transceiver(340,360) applies a transceiving signal to the unit antenna according to a control signal of the unit controller.
