Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a train control device for generating a speed check pattern and controlling the running of a train according to the generated speed check pattern.

[0002]

2. Description of the Related Art Conventionally, a parabolic speed checking pattern as shown in FIG. 3 has been known as a speed checking pattern when a train is controlled using the speed checking pattern. The speed check pattern P 'generated by the own train A shown in FIG. 3 is such that the preceding train B is located in one traveling section T1 divided by one block section, and the traveling section T1 and the traveling section behind it. Stop S of own train a on the boundary of T2
Indicates that is set. That is, the on-board device 1 'formed around the CPU mounted on the own train A
Is configured such that when an ATC signal (information) including the position information of the stop point S is obtained from the ground side, a speed check pattern P ′ at which the train A can stop at the stop point S can be generated.

Accordingly, 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 features that the ride comfort is good and the train can be operated efficiently.

When an unplanned speed limit is suddenly applied to a train and the speed check pattern is redrawn to a lower position, for example, in FIG. 3, the speed check pattern that is redrawn is indicated by a chain line. If it is located below the speed, the speed of the train A exceeds the speed check pattern that has been reset, the ATC brake (not shown) provided on the train A operates, and the speed of the train A is reset. The speed is controlled to be lower than the speed indicated by the speed check pattern.

[0005] When the ATC brake is actuated and the actuated brake is an emergency brake, the train B is once allowed to relieve the emergency brake after being stopped, and after a predetermined operation by the driver, the emergency brake is released. Is alleviated, and then the continuation of the running of the train is started again.

As an example of the operation of the emergency brake described above, there is a case where a speed limit is temporarily specified at the meeting. The temporary speed limit at the meeting will be described with reference to FIG. 1B described in the embodiment of the present invention. The temporary speed limitation at the meeting is as shown in FIG. 1A. When the train A is operated by generating the speed check pattern P, sudden occurrence of natural phenomena such as an earthquake occurs during the running section in the speed checking pattern P (the running section T5 in the example of FIG. 1B). For a specific reason, this means that a train speed lower than the train speed indicated by the currently generated speed check pattern P is specified.

[0007] Therefore, when the temporary speed limit is specified at the meeting 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 speed check pattern that has been reset. However, when the train speed exceeds the re-checked speed check pattern, the emergency brake is activated.

[0008]

However, in the above-mentioned conventional train control device using a speed check pattern, when a temporary speed limit is specified at the meeting, an emergency brake is activated on the train and the emergency brake is released. In order to do so, the train has to be stopped once, and the train operation efficiency is reduced. For this reason, on the ground side that specifies the temporary speed limit, check the position of the running train located ahead of the temporary speed limit traveling section, check the trains that are not subject to the temporary speed limit at the encounter, and set the temporary speed limit. I had to do it.

Therefore, the present invention has been made to solve the above-mentioned drawbacks, and an object of the present invention is to adjust the speed of a train with a service brake even when a temporary speed limit is specified at the meeting, and to control the train. It is an object of the present invention to provide a train control device capable of operating a train without stopping the train.

[0010]

In order to achieve the above object, the present invention provides a train control device for controlling the running of a train according to a generated speed check pattern. A temporary speed limit information receiving means for receiving temporary speed limit information that specifies a train speed lower than a predetermined train speed in normal time, and a characteristic of a service brake of the own train when the temporary speed limit information is received. Based on the speed check pattern indicated by the temporary speed limit information, or the speed check pattern to redraw the speed check pattern by adjusting the end position of the speed check pattern to the end position of the train traveling section indicated by the temporary speed limit information Redrawing means.

[0011]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1A is a schematic diagram of a train control state using a speed check pattern P in a normal (steady state) state in which a temporary speed limit is not specified.

One travel section T8 divided by one block section
The speed check pattern P generated by the own train a that is located in is a parabolic speed check pattern.
The preceding train B is present in the traveling section T1, a stop point S is set at the boundary between the traveling section T1 and the traveling section T2 behind the traveling train T1, and the terminal position of the speed check pattern P is located at the stopping point S. A speed check pattern P is formed in the pattern.

This speed check pattern P is configured to be formed by the on-board device 1 mounted on the train based on ATC information transmitted from the ground side, similarly to a known train control device. I have. That is, the on-board device 1
The ATC information formed around the PU and applied to the rail on which the train A travels is received via a not-shown upper arm (antenna), and the stop point included in the received ATC information. It is configured to extract the position information of S and form the speed check pattern P.

[0014] The train A has the generated speed check pattern P
1A, along a running curve R indicated by a chain line in FIG. 1A based on a train speed obtained from a speed generator (not shown) provided in the train A so as not to exceed the speed check pattern P. The running control of the train is performed in the form.

The formation of the above-mentioned speed check pattern P in the on-board device 1 is updated every time the stop point S moves. That is, in FIG.
When the vehicle travels from 1 to the next travel section, the stop point S moves to the boundary between the next travel section and the travel section T1, so that the stop position of the speed check pattern P is redrawn so that the end point of the travel check pattern P becomes the travel stop point. Being updated.

If the speed of the train A exceeds the speed indicated by the speed check pattern P for some reason while the train A is running based on the generated speed check pattern P, an ATC brake (not shown) installed in the train A Is activated and the speed of the train A is reduced. In the ATC braking 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, the train B once stops and then is allowed to relieve the emergency brake, and further, the emergency brake is released after a predetermined operation by the driver. Then, the continuation of the running of the train A is started.

As described above, when the train A is running on the basis of the speed check pattern P in which the train A was generated,
A case in which the temporary speed limit at the meeting is instructed will be described with reference to the flowcharts of FIGS. 1B and 1C and FIG.

Now, it is assumed that the train A generates a speed check pattern P based on the stop point information obtained from the ground side, and is operated using the generated speed check pattern P (FIG. 1 (a) Step 100, Step 102,
Step 104 negative).

Now, as shown in FIG. 2 (b), the temporary limit speed V lower than the speed indicated by the speed check pattern P becomes lower than the speed indicated by the speed check pattern P for the traveling section T5 on the way due to abnormal weather phenomena. It is assumed that an instruction has been made (Yes at step 104). In FIGS. 2B and 2C, the temporary speed limit V
Is shown as a temporary section. The information on the temporary speed limit is included in the ATC information and transmitted from the ground side to the on-board (train A) side.

The train A which has received the temporary speed limit information generates a speed check pattern P1 up to the traveling section T5 in which the temporary speed limit is designated, based on the characteristics of the service brake provided in the own train A. (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 traveling section T5 in which the temporary speed limit is instructed and generated.

In the example of FIG. 2 (b), the train A located on the traveling section T8 receives the temporary speed limit information at the meeting, and the end position of the speed check pattern P1 which has been redrawn based on the characteristics of the service brake of the train A Is located in the middle of the traveling section T5. Further, the example of FIG.
8 receives the temporary speed limit information of the traveling section T6 at the intersection of the train A and the end position of the speed check pattern P2 which is redrawn from the characteristic of the service brake of the train A is located at the end of the traveling section T6. This is an example.

As described above, when the speed check pattern P1 (or P2) is redrawn in response to the temporary speed limit information at the encounter, the speed check pattern P1 (or P2) is drawn based on the service brake characteristics of the train A. The train A is operated using the corrected speed check pattern P1 (or P2) (step 108). Therefore,
The emergency brake does not operate.

Since the newly retrieved speed check pattern P1 (or P2) is a speed check pattern that can be braked by the service brake provided in the own train A, the emergency brake is not operated and the speed check pattern P1 (or P2) is pulled. Along the corrected speed check pattern P1 (or P2), that is, FIG.
The train B can be operated efficiently without stopping the train A on the running curve R indicated by the chain line in (b) and (c).

After the train A has passed the traveling section T5 (or T6) for which the temporary speed limit has been instructed, the stop point S
The operation of the train A is performed using the original speed check pattern P ending in (Step 110 affirmative).

[0025]

The train control device according to the present invention is a temporary speed limit information receiving means for receiving temporary speed limit information for designating a train speed lower than a predetermined train speed in normal times for a predetermined train traveling section. And, when the temporary speed limit information is received, the train speed indicated by the temporary speed limit information based on the characteristics of the service brake of the own train, or the end position of the train traveling section indicated by the temporary speed limit information, The speed check pattern is redrawn by adjusting the end position of the speed check pattern, and the speed check pattern is redrawn.Therefore, the newly read speed check pattern is used for the service brake of the own train in which the emergency brake does not operate. Because it is a speed check pattern that can be braked with, without stopping the train, the running curve according to the speed check pattern that was redrawn Thereby driving the car efficiently.
