Abstract
The present invention relates to a moving body control apparatus wherein operating control flexibility and system maintainability are improved by carrying out moving body travel control by transfer of ultrasonic wave signals between moving bodies, without intervention of a ground apparatus. An ultrasonic wave transmission apparatus (1) is provided on one train (A), and an ultrasonic wave reception apparatus (10) and a signal processing circuit (13) are provided on another train (B). The timing of transmission and reception of ultrasonic wave signals is synchronized by timing signal generating circuits (2, 11) on the respective trains, and the ultrasonic wave signals are transmitted and received via a metal transmission medium (30). The reception side train (B) measures the transmission time for the ultrasonic wave signal by means of the signal processing circuit (13), and based on the measurement result generates information necessary for train travel control.
