ば、特開昭52−143604号公報）。Conventionally, a method called a point control method has been widely used as a method of transmitting ATS information from the ground to the vehicle, and information is transmitted and received at the moment the train passes a specific point, but the device malfunctions. Since there is a great danger if information is not exchanged due to such reasons, means such as ensuring safety by exchanging information at multiple nearby points and checking mutual rationality is used. (For example, JP-A-52-143604).
