Abstract

PROBLEM TO BE SOLVED: To provide testing equipment for onboard ATC devices that makes it possible to, if no ATC signal is received on the train side, identify the reason therefor and a testing method for continuity between the on-board antenna and the receiving part in an on-board ATC device. SOLUTION: The testing equipment is provided with a false ATC signal output part 41 that outputs false ATC signals S', a transmission antenna 42, and a logic part 15. If there is no received ATC signal at startup, the logic part 15 causes the false ATC signal output part 41 to output and transmit a false ATC signal S' to the transmission antenna 42 and the signal to be taken through an on-board antenna 20 into the train. If a false ATC signal S' is not received by the receiving part 14, the logic part judges that as discontinuity between the on-board antenna 20 and the receiving part 14.

On the other hand, a running train always detects the traveling speed of its own vehicle by the speed generator 18. The own vehicle traveling speed is displayed to a driver or the like by a speedometer (not shown) provided in the train, and is output from the receiving unit 14A to the logic unit 15A.
