摘要： An object is to provide a rail fracture detection device 5 capable of detecting a fracture of a rail in a track circuit without using train positional information. The rail fracture detection device 5 detects a rail fracture in a section provided with the track circuit by determining presence or absence of a rail fracture and determining presence or absence of a train on a rail by using information on whether a relay of the track circuit is activated or deactivated and information on a current value of current flowing in the track circuit. The rail fracture detection device 5 is preferably provided in a section including a curved portion or a section including a welded portion in which a rail fracture is more likely to occur.

摘要： An object is to obtain a wireless train control method capable of stable operation. A wireless train control system includes: a track circuit state information acquisition device that generates a track circuit state signal TR indicating whether a track circuit of a track is picked up or dropped and a time-triggered track circuit state signal TR-X indicating a drop of the track circuit at a timing delayed by a set time after the track circuit state signal indicates that the track circuit is dropped; and a ground control device that generates a stop limit point of a wireless-control-compliant train 41 by using presence information if a preceding train for the wireless-control-compliant train 41 is a wireless-control-compliant train 43, and generates the stop limit points of the wireless-control-compliant trains 41 and 43 by using the track circuit state signal TR and the time-triggered track circuit state signal TR-X if the preceding train for the wireless-control-compliant train 41 is a non-wireless-control-compliant train 42. The ground control device does not update the stop limit point if the track circuit state signal TR indicates that the track circuit is dropped while the time-triggered track circuit state signal TR-X indicates that the track circuit is picked up.

摘要： An object is to provide a rail break detection device that can be achieved regardless of the environment in which rails are laid, to which an output waveform from a vibration sensor 1, which is a first vibration sensor, and an output waveform from a vibration sensor 2, which is a second vibration sensor, are input, the vibration sensors 1 and 2 being mounted on different positions of rails, and which includes a waveform similarity determination unit 43 to compare impulse waveforms separated from the output waveforms or compare continuous waveforms separated from the output waveforms, and determine similarity therebetween, and detects a break of a rail.

摘要： To provide a wireless train control system that can perform a stable operation. The wireless train control system controls a wireless-control compliant train 41 following a wireless-control noncompliant train 42 by a ground control device 10. A stop limit point of the wireless-control compliant train 41 is set by a track circuit in which a tail end position of the wireless-control noncompliant train 42 is present. By using a track-circuit state signal indicating that the track circuit is turned on or turned off and a time-element-added track-circuit state signal indicating turn-off at a timing delayed by a set time after the track-circuit state signal has indicated turn-off, when the track-circuit state signal indicates turn-off and the time-element-added track-circuit state signal indicates turn-on, it is determined that turn-off indicated by the track-circuit state signal is caused by the wireless-control compliant train 41 that is a train itself being present, and the stop limit point is not updated.
