<p>PROBLEM TO BE SOLVED: To provide a position detection system of a moving body capable of correctly detecting a position of a moving body with a simple structure.SOLUTION: The invention relates to a system for detecting a position of a moving body capable of moving in a space of n (n is an integer of 1 or more and 3 or less) dimensions. The system comprises: at least (n+1) speakers installed in the space; a controller for driving the respective speakers; a microphone mounted on the moving body and detecting sound outputted from the speakers; and a calculation device for calculating the position of the moving body, on the basis of the sound detected by the microphone. The controller drives the speakers so that at least (n+1) speakers perform output operation for outputting the sound in a predetermined order with a predetermined time interval at least once, among the at least (n+1) speakers, and the calculation device calculates the position of the moving body, on the basis of time when the sound outputted in the output operation is detected by the microphone.</p> |
