Abstract

PURPOSE:To allow stoppage at a predetermined station by applying brake forcibly when an actual speed exceeds a speed in a stop pattern under a state where a stop pattern is included in an operating pattern to be communicated between a unit mounted on a train and a plurality of ground units disposed in the vicinity of a rail. CONSTITUTION:A train number and a stop pattern signal are inputted to an input unit 4 in a unit (a) mounted on a train (x) and then they are transmitted through a transceiver 2 to ground units 10a-10d arranged along a rail. Signals received on the ground side are sequentially taken into a terminal unit (t) through relays 11a-11d and collated with stored data. The terminal unit (t) makes a decision whether a train requires stoppage or not based on train numbers taken in and delivers a stop pattern through the relays 11b-11d to a train (x) requiring stoppage. Speed in the stop pattern received by the train (x) is then campared with an actual speed and if the actual speed is higher, a controller 3 outputs a brake signal to apply brake forcibly. Consequently, the train (x) can be stopped accurately at a target point.

By combining this row number data with the train stop station pattern and vehicle selection data, A
By using the TS-P type automatic train stop device, it was possible to obtain the knowledge to control the train operation by stopping a specific train at a specific station or passing through a specific station.

The present invention was made on the basis of the above findings, and its purpose is to diversify the automatic train stopping function of the above-mentioned ATS-P type to enable efficient train operation. To provide.

[0007]

In order to achieve the above-mentioned object, a train control device according to the present invention is installed on the ground near a vehicle mounted on a train and a rail on which the train runs. In the train control device for controlling the running of the train based on the data transfer between the train and the ground plane, the onboard machine has at least the train identification data and the stop of the train. It is characterized in that input means for inputting stop data of a station to be provided is provided. Further, the on-board sending means for sending out a signal including the identification data of the train and the stop data of the station where the train should be stopped from the on-board machine to the ground machine, and the ground machine. When the received signal contains stop data that should be stopped at the station corresponding to the ground plane,
Ground sending means for sending a stop pattern generation signal from the ground unit closer to the station than the ground unit toward the onboard unit,
When the stop pattern generation signal is included in the signal received by the on-board machine, a predetermined stop pattern is generated, and the generated stop pattern and the train speed are In comparison, when the speed of the train exceeds the speed indicated by the generated stop pattern, it has a braking control means for forcibly braking.

[0008]

In the above structure, the input means is the train identification data.
The data, that is, the row number data and the stop data, that is, the stop pattern data of the station where the train should stop is input. Therefore, the onboard machine has not only the row number data but also the stop pattern data.

The on-vehicle sending means sends a signal including the row number data and the stop data to the ground plane. Then, when the signal received by the ground plane includes stop data to be stopped at the station to which the ground plane belongs, a stop pattern generation signal is output toward the onboard machine. As a result, the train runs toward the stop target point while comparing the generated stop pattern with the speed of the own train. In this run, when the speed of the train exceeds the speed indicated by the generated stop pattern, the braking control means forcibly applies braking.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a schematic configuration diagram of an apparatus according to an embodiment, in which a train A traveling on a rail R is equipped with an on-board machine a.

This onboard machine a is almost the same as the one used in the known ATS-P type automatic train stop device.
The apparatus of this embodiment is configured so that a stop pattern, which will be described in detail later, can be input.

That is, the on-board machine a includes an on-board child (an on-board antenna) 1 provided at the bottom lower portion of the train a, an amplifier circuit,
A transceiver 2 formed including a filter circuit and the like,
A controller 3 formed mainly of a micro computer,
In addition to the data used in the well-known ATS-P type automatic train stop device such as a train number, the input device 4 is also used for inputting the stop pattern data. .

The input device 4 is a well-known input device that has a built-in micro computer and can display numbers and English characters input from the denki 5 on the display unit 6.
That is, as shown in FIG.
A 4-digit number and an alphabetic character displayed at the end of the number (1234M in the illustrated example), so that the column number data can be displayed as in the conventional ATS-P type automatic train stop device. Has been done.

At the right end of the display unit 6, that is, next to the letter indicating the column number, one letter (A in the illustrated example) indicating the stop pattern is displayed. This stop pattern represents the stations at which a specific train should stop and the stations at which it should pass, and an example thereof is shown in FIG.

The stop pattern of FIG. 3 shows a part of the route from Fukushima to Yamagata. The train of stop pattern A is
It means that it will stop at Akaiwa Station and Toge Station, but it will pass Itaya Station. In addition, it means that the train of stop pattern C passes through except the Toge Station. In this example, it is shown that there are stop patterns A to S.

The ground planes b1 to bn are installed on the ground near the rail R at a predetermined interval, and the CTC center installed in the command center C via a transceiver installed in the signal station B. It is connected to the device. In the present invention, the term "ground plane" includes not only each ground plane but also the function of the CTC central unit connected to the ground plane or the terminal unit 2 described later.

Since the ground units b1 to bn have the same structure,
Here, the ground plane b1 will be described as an example. The ground plane b1
A ground element (ground antenna) 10 that receives a signal from the vehicle upper child 1 when the vehicle upper child 1 approaches a predetermined range or outputs a signal toward the vehicle upper child 1; It is composed of a repeater 11 for amplifying a signal to the vehicle or a signal from the vehicle side to the ground side, and a terminal device 12 including a code processor and a communication controller.

Next, the control operation of the apparatus of this embodiment will be described. First, prior to the operation of the train a, the input device 4 is used to set the train number, stop pattern, and the like. Among the input data, the row number and the stop pattern are not only displayed on the display section 6 of the input unit 4, but also the transceiver 2, the car top 1, and the ground plane b ( 1 (not shown in FIG. 1) to the CTC central unit of the command center C. And CT
The C central device collates with the data possessed by itself, and as a result of this collation, if there is an error in the input data, an alarm (not shown) can prompt the staff to re-input. Is configured. It should be noted that the system of this embodiment has a feature that when the CTC central system goes down, the train number data and the like can be taken in from each train, so that recovery can be performed quickly.

The basic structure of the above-mentioned telegram format sent from the onboard side (train A) to the ground side (ground unit b) is the conventional ATS-P type automatic train stop device. Although the same, the apparatus of this embodiment includes a 4-bit stop pattern and 2-bit vehicle selection, as shown in FIG.

That is, this telegram format has an 8-bit synchronization section at both ends, and a 16-bit verification section for error verification before the synchronization section on the terminal side.
A message content section consisting of 48 bits is provided between the leading synchronization section and the verification section.

As shown in the lower part of FIG. 4, details of the message content portion include an information type bit indicating that the data is ATS-P type data, a bit indicating an up or down driving direction, and the like. The respective bits are arranged in a predetermined order, and the stop pattern and the vehicle selection indicating the characteristic data of the present invention are arranged at the fourth from the head and the tail, respectively.

As described above, it is assumed that the train A has started after the input of each data for the ATS-P type including the train number data, the stop pattern data, etc. is completed. Then, it is assumed that the set stop pattern data includes stopping at A station shown in FIG.

At this instep station, four ground planes b10 to b13 are installed at predetermined intervals. These above b10-b
Out of 13, the ground machine b10 is the first to communicate with the onboard machine a of the train a, and the ground machine b13 is the last to communicate. In addition, in FIG. 5, train a is shown in a larger size than the station A home or the space between ground planes for convenience.

These ground units b10 to b13 are cyclically controlled by the terminal unit 2, that is, the ground unit b10.
The control is performed in the order of → b11 → b12 → b13 → b10 .... Therefore, these ground planes b10 to b13
Even if there are multiple trains in between, the trains can be accurately grasped without misidentifying the trains.

When the car child 1 approaches the ground child 10a of the ground machine b10 as the train a progresses, the signal from the car child 1 is taken into the ground machine b10. The captured signal includes data indicating that train B should stop at A station. In addition, since the data indicating that the train B should stop at A station are stored in advance in the terminal device D, the data from the ground terminal 10a of the next ground device b11 is checked based on the comparison of both data. , A stop pattern generation signal is transmitted.

Therefore, the train B approaches the ground element 10b, and the car child 1 receives the stop pattern generation signal. When the train A is passing through the station A without stopping, this stop pattern generation signal is not output from the ground unit b11.

The controller 3 via the train car 1 and the transceiver 2.
When the stop pattern generation signal is input to, the stop pattern is generated on the vehicle. The controller 3 generates the stop pattern according to a predetermined stop pattern stored in advance in the storage unit.
This is done by loading the After that, train a
A well-known ATS-P type automatic train stop device is controlled to travel in the same manner as when a stop signal or the like is shown. The stop pattern shown in FIG. 5 is an example of a speed limit pattern.

FIG. 5 shows a speed locus when a train attendant stops at the target stop point without knowing that the train attendant will stop at A station. Also, is a stop pattern (speed limiting pattern) loaded to the controller 3 in response to the stop pattern signal from the ground device b11.
It is). Then, is the speed locus when the regular break signal is sent from the controller 3 when the speed of the train a exceeds the speed indicated by the loaded stop pattern.

Even if the clerk knows that the vehicle will stop at A station, it may be difficult to stop at a predetermined stop point because the station is in a steep slope in the mountains. However, since the speed of the train a is restricted along the loaded stop pattern, it is possible to prevent the inconvenience of stopping the train outside the stop target point.

Even if the staff forgets to stop at A station, train A will be decelerated along the loaded stop pattern, so the risk of accidentally passing through A station is prevented. It

In FIG. 5, b12 and b13 are ground planes installed across the stop target point, of which the ground plane b12 is shown.
Is for starting a timer for releasing the loaded stop pattern, and the ground plane b13 is a signal for releasing the loaded stop pattern at the end of the predetermined count of the timer. Is for outputting. That is, when the ground unit b12 receives a signal from the vehicle, a timer (not shown) is started. When the time set in the timer has elapsed, the ground pattern b13 outputs a stop pattern release signal. Therefore, if the train a does not stop at A station, that is, if it passes the ground plane b13 before the time is up, the stop pattern cannot be released. For this reason, the inconvenience of train A passing through Kou station by mistake is effectively prevented.
