PROBLEM TO BE SOLVED: To provide an automatic train stop device which can eliminate a signal ignorance owing to the forget fulness of a driver, to realize the further improvement of the safety, while considering of the compartibility in the operation handling and in the equipments, and can carry out the control fitting to the individual performance of the train, even though trains with various sorts of speed-reducing performances are mixed. SOLUTION: In an automatic train stop device in which the stop aspect of a signal machine is to be transmitted to a pick up from a ground element set at the position separated a specific distance from the above signal machine as a varied frequency signal, the ground element 2 is made transmittable in piles by making the informations such as the signal machine sort information, the signal aspect information, and the distance information to the signal machine, adding to the varied frequency signal, into telegram signals of digital information waves, and the pick up 3 is made possible to receive and pick out the telegram signals from the ground element 2. |
