Title:
RAILROAD CROSSING CONTROL SYSTEM AND RAILROAD CROSSING CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2021/065343
Kind Code:
A1
Abstract:
In contemporary railroad crossing control, the time from when a warning at a railroad crossing is issued to when a train arrives at the railroad crossing is always ensured as time necessary for ensuring safety at the railroad crossing. As a result, even when no obstacle is present in the railroad crossing and safety is ensured, a train cannot enter the railroad crossing until the necessary warning time has passed, and it is not possible to shorten the warning time. Thus, in order to shorten the warning time for the railroad crossing while ensuring safety, it is necessary to determine whether to allow entry of the train into the railroad crossing according to the state in the railroad crossing. In order to solve this problem, this railroad crossing control system comprises: a detector that is installed at a railroad crossing, and that transmits detection data yielded by continuously detecting the state in the railroad crossing; and a control device that receives the detection data. The control device allows entry of a train into the railroad crossing if safety in the railroad crossing can be confirmed according to the detection data.
