DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a variable-speed on-vehicle pattern train control apparatus, and more particularly to an ATS-S type automatic train stop system.

[0002]

2. Description of the Related Art FIG. 2 shows variable signal type grounding elements a1 to a3.
FIG. 1 is a schematic configuration diagram of an on-vehicle pattern type ATS-S type automatic train stop system using a vehicle. The rail (track) r on which the train A travels shown here is in a flat state with no gradient. The traffic light S is installed at a predetermined position near the rail r, and the vicinity of the rail r at a point 275 m, 610 m before the traffic light S, and a point a predetermined distance away from the point 610 m. To
A ground child a2, a ground child a3, and a ground child a1 are provided.

Each of the ground children a1 to a3 has a traffic signal S stopped and displayed (hereinafter, referred to as a ground child a2 shown in detail in FIG. 2).
At the time of "R display"), the display relay H of the traffic light S
Since R is restored (OFF), the power of the ground relay QR is cut off, a resonance circuit of the coil L and one of the capacitors C1 is formed, and the ground a1 is changed in frequency (hereinafter simply represented by frequency). ) (F1), ground child a2 resonates at frequency (f2), and ground child a3 resonates at frequency (f
3) It is configured to be able to resonate.

[0004] When the traffic light S is a caution indication (hereinafter, referred to as "Y indication") or a progress indication (hereinafter, referred to as "G indication"), the indication relay HR is operated (ON). And the power supply of the ground relays QR of each ground a1 to a3 is O
N and the capacitor C1 connected in parallel with the coil L
, C2 and a resonance circuit is formed.
Are configured to be able to resonate at the frequency (f0).

Of the above-mentioned frequencies (f0 to f3), the frequency (f1) indicates that the forward traffic light (the traffic light S in FIG. 3) is the R signal, and the frequency (f2) is the R signal.
The distance to the forward traffic light indicating the indication is 275 m, the frequency (f3) indicates that the distance to the forward traffic light indicating the R indication is 610 m, and the frequency (f0) ) Indicates that the forward traffic signal indicates the Y indication or the G indication, and deletes the generated speed check pattern (P6 or P2 in FIG. 2; hereinafter, the speed check pattern is referred to as "check pattern"). Or no effect.

[0006] The train A is equipped with an ATS receiver 1 capable of generating a check pattern on a car. When the ATS receiver 1 receives a signal of a frequency (f0 to f3) from a ground child a1 to a3 via a vehicle child (vehicle antenna) b, the frequency in the ATS receiver 1 is received. The frequency is changed to f0 to f3) and a signal from the ground side is received. The ATS receiver 1 is configured to receive a signal from a speed generator G attached to the axle of the train A to measure the traveling distance.

In FIG. 2, when the traffic light S indicates the R indication and the train A approaches the ground child a1, the ATS receiver 1 changes the frequency (f1) from the ground child a1.
Is received, and a warning of a stop signal indicating that the traffic light S indicates the R indication is issued. Therefore, the driver can perform predetermined confirmation treatment in response to the alarm.
If the predetermined confirmation processing is not performed, a brake signal will be output.

When the train A travels and reaches the ground child a3, the ATS receiver 1 receives a signal of the frequency (f3) from the ground child a3. This frequency (f
Since the signal of 3) means that the distance to the traffic light S indicating the R indication is 610 m, the ATS receiver 1 generates a check pattern P6 shown by P6 in FIG. Then, the train A is operated under the generated check pattern P6.

When the traveling of the train A further proceeds and approaches the ground child a2, the ATS receiver 1 receives a signal of the frequency (f2) from the ground child a2. Since the signal of this frequency (f2) means that the distance to the traffic light S indicating the R indication is 275 m, the ATS receiver 1
Generates a new check pattern P2. Then, the train A is operated under the generated check pattern P2.

When the speed of the train A exceeds the generated check patterns P6 and P2, a brake signal is output from the ATS receiver 1 and the brake is automatically operated.
At least the train A is controlled so as to be able to stop at a point in front of the traffic light S indicating the R indication, and the safety of the train A is ensured.

The above description is for the case where the rail r is flat or uphill, but when the rail r is downhill, FIG.
As shown in (1), the ground children a2 and a3 are shifted and installed away from the traffic light S.

That is, when the rail r has a downward slope, the deceleration of the train A is reduced. Therefore, even if the brakes are operated when the check patterns P6 and P2 are exceeded, the vehicle can be stopped just before the traffic light S. Because it may be gone,
The ground members a3 and a2 are located farther from the traffic light S than when the vehicle is flat or uphill, depending on the degree of the gradient. FIG.
In FIG. 3, the grounding elements a3 and a2 indicated by chain lines indicate the installation positions at the time of flat or uphill in FIG.

[0013]

In the conventional variable-speed on-vehicle pattern train control device described above, when the track has a downward slope, the ground pattern is shifted in accordance with the downward slope, so that the check pattern is also shifted. (See the difference between the check patterns P6 and P2 between the solid line and the chain line in FIG. 3). Therefore, unless the train speed is set to a low speed just before the stop target sign, for example, before about 100 m, the brake is activated, which causes a disadvantage that smooth train operation is impaired.

The present invention has been made in order to solve the above-mentioned drawbacks, and an object of the present invention is to generate a check pattern in accordance with the installation position of a traffic light even if a track has a downward slope. It is an object of the present invention to provide a variable-speed on-vehicle pattern train control device capable of performing the above.

[0015]

SUMMARY OF THE INVENTION A variable-speed on-board pattern train control apparatus according to the present invention has the following objects.
A variable-speed on-board pattern train control device that generates a predetermined speed check pattern based on a predetermined signal sent from the ground child, checks the generated speed check pattern and the train speed, and controls the train In addition, the ground piece is constituted by a pair of ground pieces provided at a predetermined interval corresponding to a descending gradient in a traveling direction of the train, and a predetermined ground piece transmitted from the pair of ground pieces is provided. It is characterized in that it has train control means for performing predetermined train control based on signals and installation information between the above ground terminals.

[0016]

FIG. 1 is a block diagram showing an embodiment of the present invention.
Description will be made based on the drawing of FIG. The same components as those in FIGS. 3 and 4 are denoted by the same reference numerals, and the description of these components will be repeated.

The rail r shown in FIG.
% (Where "%" represents per mille; the same applies hereinafter; see the symbol of the gradient in FIGS. 1 (a) and 3). Note that, as shown in the table of FIG.
The design value is up to 5%.

In FIG. 1A, a4 is a fixed signal type marker grounding element, which is configured to always resonate at a frequency (f4). The grounding element a4 is installed at a predetermined distance L corresponding to the downward slope of the track, that is, at an interval of 4 m, in a direction away from the traffic signal S than the grounding element a1.

As shown in the table of FIG. 1 (b), the installation distance L between the ground child a1 and the ground child a4 is 4 m, 9 m, 14 m, and 19 m depending on the degree of the downgrade of the track.
The information of the installation interval L, the degree of the downward gradient, and the positions of the check patterns P6 and P2 corresponding to the gradient are stored in a memory (not shown) of the ATS receiver 1 in advance.

The ground terminal a2 and the ground terminal a3 are installed so as to be slightly away from the traffic light S as compared with the flat or upward slope shown in FIG. That is, ground child a2
Is located 20 m away from the traffic light S and the ground child a3 is located 45 m away from the traffic light S. Similarly, the down slope is 15%, 25%, 3
In the case of 3%, the installation positions of the ground children a2 and a3 are as shown in FIG.
As shown in (b), it is installed so as to be far from the traffic light S in accordance with the degree of the descending gradient.

In the variable-speed on-vehicle pattern train control device having the above structure, when the train A reaches the marker ground child a4, the ATS receiver 1 transmits the frequency (f) from the ground child a4.
4) The signal is received. The ATS receiver 1 that has received this signal starts measuring the traveling distance of the train A based on the signal from the speed generator G.

When the train A approaches the ground child a1 with the traffic light S indicating the R indication, the ATS receiver 1
The signal of the frequency (f1) is received from the ground child a1 and the timing when the signal is received is received from the ground child a4 to the ground child a1.
Distance, that is, 4m is detected, and the descending gradient is 5%
You can know that it is a railroad. Based on this information and the data stored on the car, the ground child a3 is 655 m
At this point, it can be seen that the ground child a2 is installed at the 295m point. Further, based on the received signal (f1), a warning of a stop signal indicating that the traffic light S indicates the R indication is issued. Therefore, the driver can perform predetermined confirmation treatment in response to the alarm. If this prescribed check is not performed,
A brake signal will be output.

When the traveling of the train A advances and reaches the ground child a3, the ATS receiver 1 receives a signal of the frequency (f3) from the ground child a3. This frequency (f
Since the signal of 3) means that the distance to the traffic light S indicating the R indication is 655 m, the ATS receiver 1 uses the down slope 5 detected from the installation interval L between the ground child a4 and the ground child a1. The reference pattern P6 shown in P6 of FIG. Then, the train A is operated under the generated check pattern P6.

When the traveling of the train A further proceeds and reaches the ground child a2, the ATS receiver 1 receives a signal of the frequency (f2) from the ground child a2. Since the signal of this frequency (f2) means that the distance to the traffic signal S indicating the R indication is 295 m, the ATS receiver 1
Generates a check pattern P2 in consideration of the fact that the line is a 5% -downgraded line detected from the installation interval L of the ground child a4 and the ground child a1. Then, the train A is operated under the generated check pattern P2.

The above-mentioned generated inspection patterns P6 and P2
Is generated such that the stop position when the driver of the train A misses the braking timing becomes the position in front of the traffic light S. Therefore, when the train is controlled under these check patterns P6 and P2, The trainer can stop the train A in accordance with the position of the stop target sign M.

When the speed of the train B exceeds the generated check patterns P6 and P2, a brake signal is output from the ATS receiver 1 and the brake is automatically activated,
At least the train A is controlled so that it can be stopped at a point before the traffic light S, and the safety of the train A is ensured.

In the above example, the down slope of the track is 5%, but the control is similarly performed when the down slope is 15%, 25% and 33%.

FIG. 1A shows a case where the traffic light S is in the R display. When the traffic light S is in the Y display or the G display, signals of the frequency (f0) are transmitted from the ground terminals a1 to a3. Since it is output, no check pattern is generated. Also, after the train A passes the ground child a3, the frequency (f
When the signal 0) is received, the check pattern P6 generated up to that point is cleared.

In the above-mentioned example, the ground child a4 is installed before the ground child a1, but the ground child a4 may be installed after the ground child a1.

The variable-speed on-vehicle pattern train control device according to the present invention generates a predetermined speed check pattern based on a predetermined signal transmitted from a ground child, and generates the generated speed check pattern and train speed. A variable-type on-board pattern train control device that performs a train control by checking a train, wherein the ground child is provided on a pair of grounds provided at a predetermined interval corresponding to a descending gradient in a traveling direction of the train. And a train control means for performing a predetermined train control based on a predetermined signal transmitted from the pair of ground children and installation information between the ground children, so that the check pattern can be set as a stop target sign. It can be generated according to.
