Title: Train-approach alarming system
Inventor: SATO HIROSHI
IPC: B61L23/06
Filed: 1996-06-14
Abstract: PROBLEM TO BE SOLVED: To carry out railway maintenance work safely by providing an alarm generating means giving an alarm on the basis of an output signal from a train-approach detecting means. SOLUTION: An alternating action between flip-flops 85, 86 is stopped when return current flows in a rail bond. If a circuit generating an alarm while using a contact 97, which is closed when a relay 96 is released, is constructed, the relay 96 in an alarm generating unit 9 is excited by means of an alternating signal 815 of an output from a train-approach detection unit 8 when no current flows in the rail bond, so that the contact 97 is opened and no alarm is generated. However, when current flows through the rail bond, alternation of an output of the train-approach detection unit 8 is stopped, and the relay 96 is released and the contact 97 is closed, so that current is fed from a power source terminal and an alarm is given.
