SIGNAL PROTECTION METHOD, SIGNAL PROTECTION DEVICE AND SIGNAL PROTECTION SYSTEM USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a method for quickly detecting the train movement across closed sections with a minimum transponder. SOLUTION: The system has a ground train controller for controlling the operation of trains, a ground communication means capable of communicating information when approaches a specific area, and a transceiver capable of transmitting the information received by the ground communication means to the ground train controller and receiving the information transmitted from the ground train controller. When the train communication means installed on a train approaches, the ground communication means receives the speed of the train to detect the position of the train. COPYRIGHT: (C)2004,JPO&NCIPI
