<p>The sensor for sensing the tracking of an unmanned cart by coding the state of the track comprises data transmitters (10-40) for coding and transmitting the detected signal by pick up coils (IA-ID), a first driver (50) for shifting the output signal of a first data transmitter to most significant bit by a selecting signal, a second driver (60) for performing the same function to the output signal of the third and fourth transmitter, a microprocessor (70), a decoder (80) for transmitting a first enable signal to the first and second driver, and a first and a second selecting circuits (90,100) trasmitting enable control signal (MG1-MG2) for selecting the output signals of the first and the second driver.</p> |
