Guideway-guided vehicle detection based on RFID system
First Claim
1. An apparatus for detecting the information about a guideway-guided vehicle having a masking component, the guideway-guided vehicle configured to follow a path of a guideway, comprising a radio frequency identification (RFID) system comprising:
- a first RFID transponder for transmitting, across the path, first RFID transponder specific information;
an RFID reader having a first antenna for receiving the first RFID transponder specific information; and
wherein the first RFID transponder and the first antenna are fixed relative to the path and on opposite sides of the path;
wherein the RFID reader is configured to continuously monitor the first transponder specific information; and
wherein the presence of the masking component of the guideway-guided vehicle between the first RFID transponder and the first antenna masks the continuous monitoring of the first RFID transponder specific information;
a second RFID transponder for transmitting, across the path, second RFID transponder specific information; and
a second antenna for receiving the second RFID transponder specific information; and
wherein the second RFID transponder and the second antenna are fixed relative to the path and on opposite sides of the path;
wherein the RFID reader is configured to continuously monitor the second transponder specific information from the second RFID transponder; and
wherein the presence of the masking component of the guideway-guided vehicle between the second RFID transponder and the second antenna masks the continuous monitoring of the second RFID transponder specific information;
wherein the first RFID transponder is separated from the second RFID transponder by a distance, along or parallel to the path, such that the presence of the masking component of the guideway-guided vehicle between the first RFID transponder and the first antenna sufficient to mask the continuous monitoring of the first RFID transponder specific information does not occur at the same time of masking the continuous monitoring of the second RFID transponder specific information.

Abstract
An apparatus for detecting the information about a guideway-guided vehicle having a masking component, the guideway-guided vehicle configured to follow a path of a guideway, comprising a radio frequency identification (RFID) system, method of making, and use thereof are disclosed. The RFID system comprises a first RFID transponder for transmitting, across the path, first RFID transponder specific information. An RFID reader comprises a first antenna for receiving the first RFID transponder specific information. The first RFID transponder and the first antenna are fixed relative to the path and on opposite sides of the path. The RFID reader is configured to substantially continuously monitor the first transponder specific information. The presence of the masking component of the guideway-guided vehicle between the first RFID transponder and the first antenna masks the substantially continuous monitoring of the first RFID transponder specific information.
