<p>PURPOSE: To extend the control range of the vehicle without adding any parts by coupling the waveforms of two contrary magnets and further shortening the interval of magnets. CONSTITUTION: Two magnets 1 and 2 are arranged in order under the road on which an unmanned vehicle is traveled. Then, a sensor 3 arranged on the lower surface of the vehicle detects these magnets 1 and 2 and draws the waveform caused by electromotive force. This electromotive force waveform is amplified by an amplifier 4, detected by a waveform detector 5, transmitted to a microcomputer 6 and judged. Then, by overlapping the waveforms, six ways of combination can be constituted by two contrary magnets 1 and 2. Besides, when the waveforms of two magnets 1 and 2 are overlapped and coupled, in order to distinguish such a signal from the other signal, the interval of two magnets 1 and 2 is shortened so that the signals can be surely distinguished.</p> |
