Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a train control device that generates a speed check pattern and controls traveling of the train along the generated speed check pattern.
[0002]
[Prior art]
Conventionally, a parabolic speed verification pattern as shown in FIG. 3 is known as a speed verification pattern when the train is controlled using the speed verification pattern. The speed check pattern P ′ generated by the own train A shown in FIG. 3 has a preceding train B in one traveling section T1 divided by a closed section, and the traveling section T1 and a traveling section behind the traveling section T1. It shows the time when the stop point S of the train A is set at the boundary of T2. That is, when the on-board device 1 ′ formed around the CPU mounted on the own train A obtains the ATC signal (information) including the position information of the stop point S from the ground side, the train stops at the stop point S. A speed check pattern P ′ that can stop the vehicle can be generated.
[0003]
Therefore, the train A is operated along the generated speed check pattern P ′ so as not to exceed the generated speed check pattern P ′. The running curve R shown in FIG. 3 shows an example in which the train A is operated along the speed check pattern P ′. Train control using such a parabolic speed check pattern P has the advantage that the ride is comfortable and the train can be operated efficiently.
[0004]
By the way, when the train is suddenly subjected to an unplanned speed limit and the speed check pattern is redrawn to the lower side, for example, in FIG. 3, the redrawn speed check pattern is lower than indicated by the chain line. The speed of train A exceeds the redrawn speed check pattern, the ATC brake (not shown) installed in train A is activated, and the speed of train A is rechecked. The speed is controlled to be equal to or lower than the speed indicated by the pattern.
[0005]
When the ATC brake is actuated, if the actuated brake is an emergency brake, the emergency brake is permitted to be released after the train B has stopped once, and further, the emergency brake is released through a predetermined operation by the driver. Thereafter, the train continues to continue running again.
[0006]
As an example in which the above-described emergency brake is activated, there is a case where a temporary speed limit is designated at the time of encounter. The temporary speed limit for the encounter will be described with reference to FIG. 1B described in the embodiment of the present invention. The temporary speed limit for the encounter is as shown in FIG. 1A. When the train A is operated by generating the speed check pattern P, sudden occurrences of natural phenomena such as earthquakes occur in the travel section in the speed check pattern P (the travel section T5 in the example of FIG. 1B). This means that a train speed lower than the train speed indicated by the currently generated speed check pattern P is designated.
[0007]
Therefore, if a temporary speed limit is specified at the encounter while the train is running, the speed check pattern is redrawn based on the temporary speed limit, and the train is operated based on the redrawn speed check pattern. When the train speed exceeds the revised speed check pattern, the emergency brake is activated.
[0008]
[Problems to be solved by the invention]
However, in the train control device using the conventional speed check pattern described above, when the temporary speed limit is designated at the time of encounter, the emergency brazier is activated on the train, and the train must be stopped once to release the emergency brake. In other words, the operation efficiency of the train is reduced. For this reason, on the ground side that specifies the temporary speed limit, check the position of the train in operation that is located in front of the temporary speed limit travel section, check the train that does not receive the temporary speed limit at the encounter, and set the temporary speed limit. There was a hassle of having to do it.
[0009]
Therefore, the present invention has been made to solve the above drawbacks, and its purpose is to stop the train by adjusting the speed of the train with the service brake even if the temporary speed limit is specified at the encounter. It is providing the train control apparatus which can perform a train operation without.
[0010]
[Means for Solving the Problems]
In order to achieve the above object, the train control device according to the present invention is a train control device that controls a train along a generated speed check pattern. The temporary speed limit information receiving means for receiving the temporary speed limit information specifying a train speed lower than the speed, and the temporary speed limit information based on the characteristics of the service brake of the own train when the temporary speed limit information is received. A speed check pattern redrawing means for matching the end position of the speed check pattern with the end position of the train travel section indicated by the train speed indicated by the temporary speed limit information, or by redrawing the speed check pattern. It is a feature.
[0011]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings. Fig.1 (a) is the schematic of the train control state using the speed check pattern P in the normal (steady) state where the temporary speed limit is not designated.
[0012]
The speed check pattern P generated by the own train a staying in one travel section T8 divided by one closed section is a parabolic speed check pattern. Here, the preceding train B is present in the travel section T1. In addition, a stop point S is set at the boundary between the travel section T1 and the travel section T2 behind the travel section T1, and the speed check pattern P is formed so that the end position of the speed check pattern P is located at the stop point S. .
[0013]
This speed check pattern P is configured to be formed by the on-board device 1 mounted on the train, based on the ATC information transmitted from the ground side, similarly to the known train control device. That is, the on-board device 1 is formed around the CPU, receives ATC information applied to the rail on which the train a travels, via an unillustrated on-board child (antenna), and receives the received ATC information. The speed check pattern P is formed by extracting the position information of the stop point S included therein.
[0014]
In order to prevent the train A from exceeding the generated speed check pattern P, the traveling curve R indicated by the chain line in FIG. 1A is based on the train speed obtained from the speed generator (not shown) provided in the train A. Thus, the traveling control of the train is performed along the inside of the speed check pattern P.
[0015]
The formation of the above-described speed check pattern P in the on-board device 1 is updated each time the stop point S moves. That is, in FIG. 1 (a), when the preceding train B enters the next travel section from the travel section T1, the stop point S moves to the boundary between the next travel section and the travel section T1, so the speed check pattern P It is redrawn and updated so that the end position of is the stop point moved.
[0016]
Based on the generated speed check pattern P, when the train A is running, if for some reason the speed of the train A exceeds the speed indicated by the speed check pattern P, an ATC brake (not shown) installed in the train A is activated. As a result, the speed of train i will decrease. In this ATC brake operation, when the service brake output S1 is output from the on-board device 1, when the speed of the train A becomes lower than the speed indicated by the speed check pattern P, the service brake is released by a predetermined operation of the driver. Then, the train traveling along the speed check pattern P can be performed again. On the other hand, when the emergency brake output S2 is output from the on-board device 1, after the train B stops once, the emergency brake is released, and the emergency brake is released through a predetermined operation by the driver. After that, the continuation of the travel of train A is started.
[0017]
As described above, in the case where the temporary speed limit of the encounter is instructed when the train is traveling based on the speed check pattern P in which the train is generated, FIGS. 1B and 1C are used. This will be described with reference to the flowchart of FIG.
[0018]
Now, it is assumed that the train A generates a speed check pattern P based on stop point information obtained from the ground side, and is operated using the generated speed check pattern P (see FIG. 1A). Step 100, Step 102, Step 104 negative).
[0019]
Now, as shown in FIG. 2 (b), it is assumed that a temporary limit speed V, which is lower than the speed indicated by the speed check pattern P, has been instructed for the traveling section T5 due to an abnormality in the weather phenomenon or the like. (Yes at step 104). In FIGS. 2B and 2C, the temporary speed limit V section is shown as a temporary section. This temporary speed limit information is included in the ATC information and sent from the ground side to the vehicle (train A) side.
[0020]
The train A that has received the temporary speed limit information generates a speed check pattern P1 up to the travel section T5 that is designated for the temporary speed limit based on the characteristics of the service brake that the own train A has (step 106). ). That is, when the temporary speed limit information is received, the speed check pattern P1 that can be decelerated by the service brake provided in the own train A is redrawn to the travel section T5 in which the temporary speed limit is instructed.
[0021]
In the example of FIG. 2 (b), the train a in the travel section T8 receives temporary speed limit information at the beginning, and the terminal position of the speed check pattern P1 redrawn from the characteristics of the service brake of that train is the travel section. This is an example located in the middle of T5. In the example of FIG. 2 (c), the speed check pattern P2 is obtained by receiving the temporary speed limit information of the traveling section T6 at the beginning of the meeting of the train B existing in the traveling section T8 and redrawing from the characteristics of the service brake of the train A. This is an example in which the end position of is located at the end of the traveling section T6.
[0022]
As described above, when the speed check pattern P1 (or P2) is redrawn upon receiving the temporary speed limit information at the time of encounter, the speed check pattern P1 (or P2) is redrawn based on the regular braking characteristics of the train A, The train A is operated using the redrawn speed check pattern P1 (or P2) (step 108). Therefore, the emergency brake does not operate.
[0023]
This newly redrawn speed check pattern P1 (or P2) is a speed check pattern that can be braked by the service brake installed in the own train A. It is possible to drive efficiently along the speed check pattern P1 (or P2), that is, without stopping the train A on the running curve R indicated by the chain line in FIGS. 1 (b) and 1 (c).
[0024]
After the train A has passed the travel section T5 (or T6) in which the temporary speed limit is instructed, the train A is operated using the original speed check pattern P that ends at the stop point S described above (step) 110 affirmation).
[0025]
【The invention's effect】
The train control device according to the present invention comprises a temporary speed limit information receiving means for receiving temporary speed limit information for specifying a train speed lower than a predetermined train speed at a normal time for a predetermined train traveling section, and a temporary speed limit. When the information is received, based on the characteristics of the service brake of the own train, the train speed indicated by the temporary speed limit information, or the end of the speed check pattern at the end position of the train traveling section indicated by the temporary speed limit information Because it consists of a speed check pattern redrawing means that adjusts the position and redraws the speed check pattern, the newly rechecked speed check pattern is a speed check that can be braked with the service brake of the own train that does not operate the emergency brake. Because it is a pattern, the train can be efficiently operated with the traveling curve along the redrawed speed check pattern without stopping the train. It is possible to transfer.
