| Abstract(in English) | The frequency which uses the ultrasonic sensor used for a distance sensor etc. with the physical character of the element is restricted. Interference will be caused if a sensor of the same kind is simultaneously used as a result of the restriction. In order to avoid this problem, the technique in which each sensor has a unique identifier is proposed. The frequency modulation of the usual ultrasonic wave is carried out, and this identifier is convoluted. A demodulation can restore this identifier. Therefore, each sensor can be identified now. FPGA is used for the oscillation of an ultrasonic wave, and signal processing of abnormal conditions and demodulation, and distance measurement under the environment where two or more sensors active is performed on real time. |
