Description

DETAILED DESCRIPTION OF THE INVENTION (-) Description of the Technical Field The present invention relates to a method for controlling a breaker at a railroad crossing adjacent to a station.

(b) Description of Prior Art In the conventional level crossing breaker control method, when a train approaches a level crossing and enters the position of the level crossing controller (starting point), level crossing 1! l
The built-in relay activates and detects the train.
This train detection information is transmitted through the U cable to a level crossing control device installed near the level crossing, which activates a built-in relay to lower the breaker and close the level crossing, allowing the train to pass through the level crossing. When the crossing was finished, the relay built in the gate control at the end point was activated to detect the completion of the train's passage, and the relay built into the level crossing control device was restored, raising the cutoff and opening the level crossing. Therefore, the breaker continues to close the crossing where the train is located at the intersection between the starting point and the ending point (hereinafter referred to as the interruption width control section), especially at stations adjacent to stations where there is a local train overtaking waiting line. At the level crossing on the side where the departure signal is located, the local train enters the control section C and waits for overtaking III. The disadvantage was that it meant a lot of time wasted, and there were cases where they were given special treatment by the railroad crossing attendant Hibiki.

(c) Purpose of the Invention The present invention has been made in view of the above-mentioned points.The present invention has been made in view of the above-mentioned points. 1
-Even if you have a little extra time, open the shutoff 6,
To provide a safe level crossing breaker control method that is convenient for level crossing users.

(・) System Sakaki Seiban which has been thoroughly discussed above; Function example C for controlling a railroad crossing breaker will be explained with reference to two pages.

The route control device 1 enters the above-mentioned Matsutoshi 1j car waiting line Ag, and based on the status of the 9 trains, the operation information of the level crossing controller Pi, and the train operation control status based on the train operation schedule C2, the following 1:
Processes 1 to 3 to be described are program-controlled and output.

In process 1, the local train is waiting at the local train standby MAR (2), and after the express train passes the main line Al and overtakes the local U car, the continuous closed state of the breaker 3 at the level crossing makes it possible to use the level crossing. If the waiting time continues for more than the time that road users feel is the best (for example, 3 minutes), even if the local train has passed its departure time on the train schedule, it will interfere with the operation of the following train. If it is within the time (for example, 20 seconds) within the range that does not cause a problem, the departure route setting of the local train is inhibited, the control signal for opening the level crossing control device 2 and the circuit breaker 3 is output, and the signal continues for a predetermined period of time. Then cancel it.

In process 2, the local train is waiting at the local train waiting line A21; after the express train passes the main line A1 and overtakes the local train, there is sufficient margin on the train operation schedule at the departure time of the local train (for example, 20 (seconds or more), the departure course setting of the local train is inhibited, the level crossing control device 2C outputs an opening control signal for the second circuit breaker 3, and is released after a predetermined period of time.

In process 3, the local train is on the local train waiting line A! It was determined from the passing signal from the point passing detector Ell-84 that the train had entered and stopped to wait for an express train to overtake, and the train was stopped before the following express train reached the level crossing controller PI. For example, the departure course setting for the main line Al is inhibited, a control signal for opening the circuit breaker 3 is output to the level crossing control device @2, and the signal is released after a predetermined period of time has elapsed.

Note that the above processing 1 to processing Sti are not performed in sequence,
Each case is handled as it occurs.

Fig. 3 shows an example of the condition of the train during rush hour, Tl
d Jintong Yu 1j Local trains, TI and T8, which entered the car waiting line Al, are express trains, TI and T8, which continuously overtake local trains Tl.
is a train that runs on Main Line B in the opposite direction to 〒1''78.

First at Tsuta 3 Gang, local train T1m express Tari single T3 and T
8 passes each level crossing controller Pi, that is, if there is no train at the Umewari Oku Seki, the interrupt gate 3 is in an open state. When the local train Tl passes through the level crossing controller Al and enters the breaker section 2, the breaker 3 is closed in response to the operation information of the level crossing controller 2Fi and the level crossing controller Pi. The local train Tl advances further, enters the local train waiting line Ml and stops, and before the express train Ts reaches the Kamigiri controller I, the route control device 11Fi performs the above-mentioned process 3, and the main line The signal indications of the departure signals I and 1 are stopped and the breaker 3 is opened for a predetermined time by the level crossing control device 2 via the crossing signal output unit 1 [device 7]. After the express trains T2 and T8 proceed from the above state and overtake the local train T1, the continuously closed state of the breaker 3 at the level crossing continues for a period of time that is felt to be a long waiting time for road users using the level crossing C. , even if local train T1 has passed the departure time on the train operation schedule, if it is only for a short time, the course will be changed to 1tll.
If the above process 1 is carried out, and there is sufficient margin on the train operation schedule at the departure time of the local train, the above process 2 is carried out as a village, and the local train waits #MA.
The signal display of the departure signal Lz of s is stopped and the signal display is changed to 1. The circuit breaker 7 is opened and the breaker 3 is opened for a predetermined period of time by the level crossing control device 2.

(f) Effects of the Invention As explained above, according to the Ejj4+2 of the present invention, the train operation schedule is stored, and the relay interlocking device is activated from the route control device f2 based on the train operation schedule and the actual train running condition. The control information on the so-called train operation schedule, which controls the route of the train and the current control of departure signal No. 16, is combined with the breaker control information of the level crossing control device. Station C: If used to control the breaker at the adjacent level crossing, it will be possible to open the breaker based on the actual operating conditions of the tally car, allowing the slightest margin of time for train operation control to be seen in minute detail. , it is possible to provide services to level crossing passers beyond human ability that conventionally could not be provided by both crossing staff, and the safety logic of the hoof cutting @ device remains the same as before; Since it is no longer necessary to release the shutoff, which was done in a peer system separate from the mechanical system of the control device, wages can be reduced.
