Abstract
The invention provides an RFID asset monitoring system which comprises a reader, a relay locator and terminal labels, wherein the relay localizer actively sends a locating identification code to the relay locator by means of radio frequency (RF) to cover all terminal labels of a region. The terminal labels in the region receive the sent locating identification code and judge the locating identification code. Judging that the locating identification code is changed (namely the change of the positions of the terminal labels) or the same locating identification code is received to achieve the predetermined times, the terminal labels directly transmit a signal to the reader or transmit the signal to the relay locator and transfer the signal from the relay locator to the reader to acquire the region where the object is located at present. The signal transmitted by the terminal labels comprises the locating identification code and a self-identification code. The invention also provides an RFID asset monitoring method. The invention is used for reducing the postback data quantity of terminal labels, thereby effectively reducing the power consumption of the terminal labels and the setup cost of the whole system.
