A mobile RFID (Radio Frequency Identification) system and method are provided to monitor multiple control zones of the system simultaneously through a mobile outpost monitor. The control zones included in the system are connected with each other through a data exchange interface. Each of the control zones includes a link interface connecting with a gateway of at least one RFID tracking module. The gateway connects with at least one RFID reader and a signal transmitter to receive tag information of RFID tags within the control zone, and transmits the tag information through the signal transmitter. When the mobile outpost monitor moves from one control zone to another, the mobile outpost monitor may switch to link with the signal transmitter of the gateway in the current control zone. Through the data exchange interface, the mobile outpost monitor is able to obtain the monitoring information of another control zones.

Mobile RFID monitoring system and method thereof

A positioning system and method are provided to use multiple RFID readers to position a target object with an active RFID tag equipped thereon. The system and method defines a geometric center of the locations of the RFID readers as a first coordinate. When the RFID readers continuously receive RF signals of the active RFID tag, a corresponding signal intensity of each of the RF signals is calculated and compared to obtain an approaching vector corresponding to the location of the RFID reader with the greatest signal intensity of the RF signal. A positioned location of the target object is then approached from the first coordinate to a second coordinate according to the approaching vector. The first coordinate and the positioned location of the target object will be reset as the second coordinate. The reset first coordinate is output as the latest positioned location of the target object.
