An example of a railroad crossing control method in which a railroad crossing control command C is transmitted from above to the railroad crossing LC and the railroad crossing stop traveling control pattern PTL on the train TR is released by a response signal CA from the railroad crossing LC and a normal railroad crossing signal LA will be described. The operation control device TCD counts the cumulative traveling distance by the number of rotations of the axle and detects the traveling position Pt of the train TR and the number of rotations of the axle per unit time detected by a known method of correcting the absolute distance at a specific point. Based on the speed Vt of the train TR detected by a known method to calculate the speed and the stored crossing position Pl, the appropriate timing time Tc for controlling the crossing LC is calculated, and the crossing LC is calculated at the time Tc.

献できる。When operating a high-speed train, it is not necessary to repair the position of the track circuit or the level crossing controller as a measure for speeding up the level crossing to secure the warning time of the level crossing. It is possible to flexibly cope with the reverse direction operation in the double track section without adding equipment. Except for the shortcomings of the conventional method of optimizing the warning time of railroad crossings, where the warning time varies depending on the speed of the train and the operating status of the train, it is possible to equalize the warning time with high accuracy,
In terms of safety, the alarm time does not become shorter than the predetermined value. For all trains including high-speed trains, when an abnormality is detected at the railroad crossing, it is possible to stop before the railroad crossing, and it is possible to minimize the warning time for the railroad crossing under the conditions. It is possible to prevent unauthorized operation of a railroad crossing due to rust or dirt on the rail tread, which cannot be avoided by the current train detection method for railroad crossing control. These effects will greatly contribute to the leveling control method for responding flexibly and safely to changes in train operating conditions, and to the optimization of leveling alarm time, which is now a socially important issue. it can.

許容する 特許請求の範囲第１項記載の踏切制御装置。2. The operation control device (TCD) obtains in advance the time (T1) at which the train (TR) reaches the railroad crossing (LC) from the traveling control pattern (PT) of the train (TR), and then the railroad crossing (LC). The level crossing control command (C) is set so that the level crossing warning time, which is the time from the start of the alarm to the arrival of the train (TR) at the level crossing (LC), becomes a constant value regardless of the speed and running of the train (TR). Output,
The train (TR) travel control pattern (P
The crossing control device according to claim 1, wherein only a change to a travel control pattern (PT) that does not become shorter than a predetermined alarm time is allowed when T) is changed.

The operation control device (TCD) calculates a value obtained by subtracting the time required for level crossing control from the arrival time until the train (TR) contacts the level crossing stop traveling control pattern (PTL), and also calculates the value. And the train (TR) stops at the railroad crossing control pattern (PT
L) Level crossing Stop traveling control pattern (PTL)
The railroad crossing control device according to claim 1.
