Abstract:
An information generating apparatus using elastic waves, which employs a rail for a train as a transmission medium, comprising:elastic wave transmitting means for transmitting elastic waves to said rail;elastic wave receiving means for receiving elastic waves transmitted from said elastic wave transmitting means through said rail; andinformation generating means for generating information that is necessary for controlling/monitoring associated elements of a control system for performing control operations on said train, based on an elastic wave reception signal received by said elastic wave receiving means,wherein said information generating means has judgment means for making a judgment on presence/absence of rupture in said rail, based on a reception condition of an elastic wave received by said elastic wave receiving means compared with a predetermined condition and for generating information representing presence/absence of rupture in said rail.
