IPC: B61L3/12
Filed: 1999-08-31
Abstract: PROBLEM TO BE SOLVED: To accurately detect a train, and to detect the train passing direction and a train speed on the ground by arranging a ground responder by keeping an interval simultaneously uncommunicable with an interrogator. SOLUTION: An on-vehicle responder c1 is formed as a responder on the forefront car since it is arranged in the traveling directional forefront part of a train, and an on-vehicle responder c2 is formed as a responder on a rear car since it is arranged in the rearmost part of the train. These both on-vehicle responders c1, c2 are arranged in a position communicable with an interrogator (a) when the train travels and is opposed to the position of the interrogator (a). Thus, the interrogator (a) can specify the train by sending out a response signal from the responder c1 on the forefront car when a question signal is sent out to the forefront vehicle responder c1. That is, the response signal sent out of the responder c1 on the forefront car plays a role of announcing the train to the ground interrogator (a).  The responder c2 on the rear car similarly communicate with the interrogator (a).
