Claims

[Scope of utility model registration request]

One beacon is installed on the ground, located at a speed check point, and transmits speed limit information corresponding to the signal display, and two beacons are installed on the train, separated by a certain distance in the direction of train travel. In addition to installing an onboard element, a variable timer that can change the measurement time depending on the speed limit information received from the beacon is installed, and when the first onboard element receives the speed limit information from the beacon, the timer is set to indicate the speed limit. A measurement time corresponding to the information is set, and when the second onboard element reaches the ground element after the first onboard element passes the ground element and before the timer expires, the operating speed is determined to be over the speed limit. An automatic train stop device characterized by outputting a brake command to the train concerned.
