DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a train control device, and more particularly to a train control device installed on a vehicle.

[0002]

2. Description of the Related Art Conventionally, as this type of train control device,
The one shown in FIG. 6 is known. That is, in this conventional apparatus, a plurality of track circuits (here, five track circuits T0 to T4 are shown) are formed by dividing a rail (track) R into a predetermined length, and each track circuit T0 is formed. Transmitters B0 to B3 for transmitting train control signals to the beginning of T4.
Are provided respectively.

From each of the transmitters B0 to B1, for example, when the own train a and the preceding train b are at the intervals shown in FIG.
A G signal indicating the progress of the train based on the position signal of the preceding train b is transmitted, a Y signal indicating a warning notice of the train is transmitted from the transmitter B2, and a train signal is transmitted from the transmitter B3. An R signal indicating stop indication is transmitted.

On the other hand, the own train a has an antenna 1
, So that the signals of the respective track circuits T0 to T4 can be received. The received signals are amplified by the amplifier 2 and then separated by the signal processor 3, so that the received signals are G,
It is configured to identify whether it is Y or R, and to drive the display 4 having lamps corresponding to the G, Y and R signals based on the identification signal. Also, when you are <br/> automatic train control system in the train a is built, not only R lamp indicator 4 is lighted, it is configured to automatically brake the R signal input is activated I have.

Accordingly, the own train a can travel at a predetermined allowable speed (for example, 55 km / h) up to the track circuits T0 and T1, and at the caution speed (for example, 2 km) in the drive circuit T2.
5 km / h), and can be operated so that it can be stopped at least in the track circuit T3.

[0006]

However, in the conventional train control device described above, since the progress or stop state of the own train is specified for each block section specified by the track circuit, the rear part of the preceding train has to be specified. Even if you are trying to get out of the track circuit (block section), the train cannot enter the track circuit, and the train interval is reduced as much as possible to increase the transportation capacity. There was a problem that it could not be shortened.

To solve such a problem, it is conceivable to reduce the track circuit (blocking section).
As the orbital circuit becomes smaller, the number of orbital circuits increases by that amount, and the transmitter and the receiver (not shown in the example of FIG. 6,
It is provided at the terminal side of each track circuit, receives a preceding train position signal, etc., and increases the number of equipment such as a succeeding train (which is transmitted to its own train), thereby increasing a new problem that equipment costs increase. appear.

Accordingly, the present invention has been made to solve the above-mentioned problems, and an object thereof is different from the above-mentioned fixed block type, in which the train can be operated in a movable block type.
An object of the present invention is to provide a train control device suitable for shortening a time interval.

[0009]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention relates to a preceding train which is located ahead of its own train.

Embodiments of the present invention will be described below with reference to the drawings. The same reference numerals are used for the same components as those in the related art,
Since the description of these constituent elements is duplicated, only new parts will be described with different reference numerals.

The transmitters A0 to A3 provided at the starting end of each of the track circuits T0 to T3 are configured to transmit the train position data of the preceding train b to the succeeding train (own train) a. That is, the preceding train b has the same tach generator (speed generator) G as that provided in the own train a described later.
T is provided, and the preceding train position data obtained from the tachogenerator is configured to be input to the transmitter. For example, in the state of the train shown in FIG. 1, the position data of the preceding train b is transmitted to the track circuit T4 via an antenna (not shown), and the position data is transmitted to a receiver (not shown) provided at the terminal side of the track circuit T4. Track circuit through T3
(See FIG. 2).

The form of the signal input to the transmitter A3 is shown in FIG.
Is modulated serial data including the position data of the preceding train b into an FSK (frequency shift keying) signal. Therefore, the transmitter A3 has a data generation circuit 11 including a demodulation circuit for demodulating the input FSK signal into serial data, and a transmission circuit for modulating the generated data again into an FSK signal and sending it to the track circuit T3. And a circuit 12.

The transmission of the position signal of the preceding train b from the track circuits T3 to T2, T2 to T1 and T1 to T0 is performed via the transmitters A2, A1 and A0, respectively, as in the case of the transmitter A3. . In other words, the transmitters A0 to A3 and the receiver (not shown) installed between the preceding train b and the own train a have a role of transmitting the position of the preceding train to the own train a by acting as a repeater. .

The signal processor 20 mounted on the own train a
The position data of the preceding train b is input via the antenna 1 and the speed signal of the tach generator TG provided on the axle is input and processed, and the display unit 30 is driven and controlled. That is, the signal processor 20 is configured as shown in FIG.
As shown in the figure, the speed detection unit 21 which calculates the speed of the own train a from the speed signal from the tach generator TG, and the position of the own train a (the head position of the own train a) from the speed and the running time of the own train a A position detection unit 22 to be calculated, a preceding train position identification unit 23 including a demodulation circuit for demodulating a signal input from the antenna 1, and a stop pattern generated by performing arithmetic processing based on data from these units 21, 22, 23 And a logical operation unit 24 for driving and controlling the display unit 30.

The logical operation unit 24 is formed of a so-called microcomputer, and has a stop obtained from the distance until the vehicle stops when the own train a is running at a predetermined speed and braking is applied. It has a characteristic diagram. Therefore, when a stop target point is set ahead of the own train a, a stop pattern having the stop target point as a stop point can be generated. When there is a preceding train on the track, the stop target point is the train position (the rear position of the preceding train).

The display unit 30 has a G lamp 31 which is turned on when the own train a is in progress and an R lamp 32 which is turned on when the train is stopped.

Next, the control operation of the apparatus of this embodiment will be described with reference to a stop pattern diagram shown in FIG. Now 2
It is assumed that two trains a and b are operated in the state shown in FIG. Therefore, the position data of the preceding train b is input to the own train a every moment, and the stop target point also moves according to the traveling speed of the preceding train b. For this reason, the stop pattern generated by the signal processor 20 of the own train a also moves according to the preceding train position.

Here, for the sake of simplicity, it is assumed that the preceding train b is stopped. If the preceding train b is stopped, the lower part of the stop pattern is fixed to the target stop point (the rear part of the preceding train). As described above, this stop pattern is a stop characteristic diagram showing a distance until the own train a stops when braking is applied while the own train a is running at a predetermined speed. Until the stop pattern generated from the position is reached, the own train a can travel at a predetermined traveling speed.

Accordingly, the stop pattern of the own train a is generated from the position of the preceding train b input via the antenna 1 at a certain running point and the running speed of the own train b at the running point input via the tach generator TG. Then, the own train a can proceed at the traveling speed from that point to the stop pattern, so the logical operation unit 24
1 is lit display, that effect Ru is informed to the driver. The logical operation unit 24 at the time when the self-train a reaches the stop pattern is detected by the position detecting section 22 by lighting display the R light 32, that fact Ru is informed to the driver.
Thus, the driver can apply braking to the own train a to stop the own train a at the stop target point. Of course, the automatic brake may be activated at the same time when the R lamp 32 is turned on.

The stop pattern is, as described above,
It is generated according to the traveling speed of own train a,
This may be generated by preparing a stop pattern based on the permissible maximum speed of the own train a, and adjusting the lower part of the stop pattern to the position of the preceding train.

As described above, according to the present embodiment, the stop target point is specified by the position of the preceding train without being specified by the track circuit (blocking section) as in the prior art. It can be approached, and the stop target point can move with the movement of the preceding train, so train operation can be performed in a so-called moving block type,
It can contribute to shortening the time interval.

FIG. 5B shows an example in which a stop notice pattern is provided in front of the stop pattern (on the own train a). The stop notice pattern is generated by moving the stop pattern forward by a predetermined distance. Then, while the own train a travels from the notice pattern to the stop pattern, the logical operation unit 24 blinks and lights the R lamp 32 to notify the driver. For this reason, the driver knows that the own train a will soon reach the stop pattern position.
Is decelerated to gradually approach the stop target point. Of course, the automatic brake may be gradually applied simultaneously with the blinking of the R lamp 32.

As described above, when the stop notice pattern is provided, the vehicle can be decelerated between the stop notice pattern and the stop pattern, so that the ride comfort can be improved.

In the above embodiment, the target stop point is specified by the preceding train. However, the stop target point may be specified by the course conditions such as drop-in lines. Further, although the display unit is a lamp display, it is needless to say that a CRT display or a sound may be used.
