<p>PURPOSE:To confirm the safety of travelling on a track with excellent workability and high safety, by providing an unmanned car to be induced with a travelling holding function in case of the interruption of electric waves, and by automatically reopening induction travelling by the returns of electric waves within a fixed time. CONSTITUTION:When there are dangers that wireless induction between an induction car A and a car to be induced B is temporarily interrupted, the following devices are mounted; a travelling holding switch munually operated in the car A before electric waves are interrupted. A timer that intentionally delays the functioning of an emergency brake, which works to the car B when electric waves are interrupted, for a fixed time and maintains the releasing conditions of zero-interlock mechanism and the emergency brake. A self-propelled holding circuit for controlling fuel by supplying with proper speed instructions during the functioning of the timer. When normal transmission and reception are recovered within a fixed time by the timer, the travelling holding switch is returned while the emergency brake is released. Thus, the safety of travelling can be affirmed.</p> |
