Intelligent object identification (the ability to find the identity, position
and orientation of an remote object) in a Manufacturing environment plays
an important role in the areas of Automation and Manufacturing. Radio frequency
identification (RFID) systems have solve the problem of finding the
identity of a remote object, but it fails to determine the position and orientation.
The Global Positioning System (GPS) have a solution to find the
position of a remote object in the global environment, but in a Manufacturing
environment it fails. The main obstacle to overcome in finding a unique
solution with radio frequency technology is reflections.
This thesis investigates the idea of finding the identity, position (and orientation)
of a (dormant) chip remotely. The chip transmits a binary signal at
244kHz. The string is Amplitude modulated. The receiver demodulates the
signal to obtain the chip's identity. The receiver antenna is divided into four
quadrants. First the quadrant in which the chip is located are determined.
Three different voltages are then measured to obtain the position of the chip
in the specific quadrant.
Reflections can be ignored since the system works at a low frequency.
