Description

Train security system and method

The present invention relates to a train security system and a method thereof, and is particularly suitable for application to a train security system in which an axle counter is reset using a train security device.

In general railways, the position of the train is detected using an axle counter. The axle counter includes a detection device in which detectors are installed at both ends of one section. The detection device is a detector at the section start point, and adds a counter each time the train axle passes through the section start point. Similarly, the detector is a section end point detector, and decrements the counter every time the axle passes the section end point. If the counter value is zero after subtraction, it means that the train is not on that section and the next train can enter.

The axle counter 10B includes an evaluator 16B and a detection device 11B.

Similarly, the axle counter 10E counts the number of axles detected by the detection device 11E. The evaluator 16E counts the number of axles that have entered the area of the detection device 11E and the number of axles that have advanced from the area of the detection device 11E. The axle counter 10E includes an evaluator 16E and a detection device 11E.

The signal device 14A is connected to the interlocking logic unit 12A, the signal device 14B is connected to the interlocking logic unit 12B, and the signal device 14E is connected to the interlocking control unit 17. Signal devices 14B1 and 14B2 are connected to the interlocking logic unit 12B.

The interlocking logic units 12A and 12B and the interlocking control unit 17 are connected via a network 30.

(2) Axle Counter Reset Processing According to the Present Embodiment FIG. 2 shows an example of a processing procedure of axle counter reset processing in which the interlocking logic unit 12A resets the count value of the axle counter 10. The interlocking logic unit 12A resets the count values of all the axle counters 10 between the A station and the B station according to the processing procedure shown in FIG.

When it is necessary to reset the count values of the

evaluators

16A, 16B, and 16E between the stations A and B, the station staff at the station A visually confirms that no train is present between the stations A and B. Thereafter, the station staff at the station A performs a reset operation of the axle counter 10 through the man-machine interface unit 13A and makes a reset request (SP101).

The interlocking logic unit 12A receives a reset request from the man-machine interface unit 13A, and notifies the interlocking logic unit 12B of the reset request via the network 30.

The interlocking logic unit 12B notifies the man-machine interface unit 13B that it is waiting for approval. The interlocking logic unit 12B waits for an approval operation from the station staff of the station B via the man-machine interface unit 13B for a predetermined time, and determines whether there is an approval (SP102). If a negative result is obtained in this determination, the process returns to step SP101. The station staff at station B visually confirms that there is no train between station A and station B, and then performs an approval operation.

If an affirmative result is obtained in step SP102, the interlocking logic unit 12B transmits the approval information to the interlocking logic unit 12A via the network 30. Receiving the approval information, the interlocking logic unit 12A performs a train presence confirmation process between the A station and the B station (SP103).

FIG. 3 shows an example of a processing procedure of a train presence line confirmation process between the A station and the B station executed by the interlocking logic unit 12A. The interlocking logic unit 12A confirms whether a train is present between the station A and the station B according to the processing procedure shown in FIG.

The interlocking logic unit 12A acquires the number of axles (a) and the passing direction (b) of the axles that have passed through the A station entrance / exit detector 101, which are count values of the A station entrance / exit detector 101, from the evaluator 16A (SP201). ).

The interlocking logic unit 12A transmits the count value of the A station entrance / exit detector 101 to the interlocking logic unit 12B via the network 30.

When the interlocking logic unit 12A obtains the count value, it determines whether there is an axle that has passed through the A station exit detector 101 and whether the passing direction is the traveling direction (a> 0 & b = traveling direction?) (SP202). ). If a negative result is obtained in this determination, the process proceeds to step SP206.

If the interlocking logic unit 12A obtains a positive result in step SP202, it determines that the train is on the line between the A station and the B station (SP203). By this determination, the interlocking logic unit 12A updates the ascending line in the A-B column T12 of the A station table T1, which is a table of the train line information shown in FIG.

The A station table T1 is held by the interlocking logic unit 12A, and the B station table T2 is held by the interlocking logic unit 12B. The contents of the change are always reflected via the network 30 so that the contents of the A-B column T12 of the A station table T1 and the A-B column T21 of the B station table T2 are kept the same. For example, it is confirmed whether or not there is a change at a cycle of 500 milliseconds. If there is a change, the change contents are reflected in both tables.

In the present embodiment, the direction from A station to B station is the up direction, while the direction from B station to A station is the down direction. Further, in this embodiment, two tracks are laid, one for each of the train for the up train and one for the down train. For this reason, the A station table T1 and the B station table T2 in FIG. 4 include an ascending line and a descending line.

In addition, each table holds information on the line between adjacent stations. For example, the B station table T2 includes an AB line T21 which is information on the line between the A station and the B station between the B station and the A station adjacent to the B station, and the C station where the B station is adjacent on the other side. And B-C column T22 which is information on the line between the B station and the C station.

Since station A is the first station, no on-line information is stored in column T11. As for the terminal station, only one column is retained as in the first station.

After the interlocking logic unit 12A updates the A station table T1, the interlocking logic unit 12B receives the number of axles that have passed through the B station entrance detector 102, which is the count value of the B station entrance detector 102, from the evaluator 16B ( c) and the passing direction (d) are acquired (SP204).

When the interlocking logic unit 12B acquires the count value of the B station entrance / exit detector 102, the count value of the B station entrance / exit detector 102 and the count value of the A station entrance / exit detector 101 transmitted from the interlocking logic unit 12A. Compare with. That is, the interlocking logic unit 12B determines whether the number of axles that have passed through the A station entrance / exit detector 101 is equal to the number of axles that have passed through the B station entrance / exit detector 102, and has passed through the A station entrance / exit detector 101. It is determined whether or not the traveling direction of the axle and the traveling direction of the axle that has passed through the B station entrance / exit detector 102 are equal (a = c & b = d?) (SP205). When the interlocking logic unit 12A obtains a negative result in this determination from the interlocking logic unit 12B, the interlocking logic unit 12A ends the train presence line confirmation process between the A station and the B station when it is transmitted via the train presence line information table.

When the interlocking logic unit 12B obtains a positive result in step SP205, the interlocking logic unit 12B determines that there is no train between the station A and the station B (SP206). As a result of this determination, the interlocking logic unit 12B updates the up line in the A-B column T12 of the B station table T2, which is a table of train line information shown in FIG. 4, to 0 (non-line).

The contents of the change are always reflected via the network 30 so that the contents of the A-B column T12 of the A station table T1 and the A-B column T21 of the B station table T2 are kept the same. For this reason, the interlocking logic unit 12A recognizes that the train is not between the A station and the B station.

When the interlocking logic unit 12A acquires information on the presence / absence of the line between the A station and the B station, the interlocking logic unit 12A determines whether the train is on the basis of this information ( SP104). If a negative result is obtained in this determination, the process returns to step SP101.

When the interlocking logic unit 12A obtains a positive result in step SP104, it resets the count values of all the axle counters 10 between the A station and the B station (SP105).

Specifically, the axle counter 10A is instructed to reset via the interlocking logic unit 12A, the axle counter 10B is instructed to reset via the interlocking logic unit 12B, and the axle counter 10E is reset via the interlocking control unit 17. Instruct.

(3) Effects of the present embodiment When the axle counter 10 is reset, in addition to the work of confirming that the trains are not on the line between the stations, the train security system 1 is also installed at both stations. Make sure that the train is out of service. For this reason, it is possible to prevent human error and to ensure safety by suppressing the reset operation of the axle counter when there is a train between stations.
