PROBLEM TO BE SOLVED: To provide a pantagraph state detection system which is capable of highly accurately detecting states of a pantagraphs.SOLUTION: A pantagraph state detection system comprises: sensor terminals 1 (1-1) installed on a movable part of each of plurality of pantagraphs of a train; driving panel terminals 3 (3, 3) installed on driving panels; and relay terminals 2 (2-2) which relay radio signals between the sensor terminals 1 and the driving panel terminals 3. The sensor terminals 1 detect whether the pantagraphs on which they are installed are in a raised state or not by using an acceleration sensor, and the driving panel terminals 3 collect state detection results of pantagraphs by the sensor terminals 1 and output them to notification devices to a driver. |
