Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention provides a signaling system capable of high speed operation of 130 km / h or more.

[0002]

2. Description of the Related Art An existing signal system using a ground light signal is built on the assumption that the line-of-sight distance of the signal is 600 m.

In order to improve the speed significantly exceeding 130 km / h such as 160 km / h, the speed limit within the line-of-sight distance from the maximum speed to the Y indication is set, for example, 55.
Although it is necessary to decelerate to km / h, the braking distance will be insufficient if deceleration considering passenger comfort is taken into consideration.

For this reason, in G, the existing 130 km /
In order to enable high-speed running at 160 km / h, etc., with h as the speed limit, a signal called GG indication is newly provided before G indication or an in-car signal such as ATC (Automatic Train Controller) is set. It was thought that such a method was necessary.

[0005]

Although vehicle control technology has advanced and speed improvement is becoming a practical issue, in order to make the signal system compatible with high-speed operation, all of the colored light traffic signals must be repaired or ATC or the like must be used. It is necessary to install another system, which necessitates a large investment.

Even if the speed can be increased, only a part of the high-speed trains will run, the existing trains will continue to run as usual, and a wide section of the high-speed trains is desired. It becomes a scale.

[0007] Therefore, it has been desired to provide a signal system which can improve the speed economically by effectively utilizing the existing signal system without modifying the existing color light signal system as much as possible. No such method has been proposed.

[0008]

[Means for Solving the Problems] Then, the existing ATS-S
Type equipment is used effectively, and by adding one more information to equipment that used to perform only two types of control, stopping or proceeding, be careful of the case of G indication signal (including deceleration signal) It makes it possible to distinguish the case of the display signal, and facilitates the improvement of functions on the vehicle.

Therefore, in the conventional ATS-S type, it is 1 or 0.
The line provided for transmitting the presence / absence of the voltage corresponding to the signal (whether it is progress or stop) is used as a line for transmitting three kinds of signals of current polarity and no current.

The existing ground element (4) has a braking distance of 6
It uses the fact that it is installed at 700-800m, which is set to 00m in consideration of the distance traveled during free running by checking for 5 seconds after receiving the signal. By encouraging the eyes to treat the brakes, it is possible to decelerate to the speed required by the corresponding traffic signal.

For this reason, in addition to displaying the advance notice on the vehicle when the caution information is received, it is possible to travel at the maximum speed to the next point when the progress information is received, while the deceleration pattern to the corresponding traffic signal is received when the caution information is received. (16) When the stop information is received, the stop pattern (1
7) is generated and the on-board safety device having a function of checking the traveling speed and the speed on the pattern to prevent the speed from being exceeded is mounted on a high-speed vehicle.

[0012]

As a result, the speed can be improved with the existing color light signal system as it is, and continuous security control from high speed running to stop can be realized.

Also, since the existing equipment of the existing ATS-S type is used for the necessary equipment, the speed can be improved with a minimum construction cost. In addition, operation and handling of crew members will be possible with the current extension, and the system of the signaling system can be maintained.

Further, the editing unit (7) is added to each of the connection units (3) and added.

The signal display determination section (6) selects three-value information of progress, caution, and stop based on the color light signal display control condition,
The data is transmitted to the transmission line (2) via the transmission unit (1). Here, the ternary information of progress, attention, and stop is associated with the polarity (+, −) of the current (i) and no current.

In addition, the editing section (7) which has received this information transmits the corresponding information from the information transmitter (5) onto the vehicle, and the progress condition (11) for the progress information and the caution information. ), And for the stop signal, the stop condition (12) is transmitted to the ground element (4) via the junction box.

As a result, the same control conditions as before are transmitted from the existing ATS ground element (4).
Information corresponding to progress, caution, and stop is transmitted from the information transmitter (5) attached to the ground robot (4), and the vehicle equipped with the onboard safety processing unit (CP) receives this information. it can.

Of course, it is possible to share the information transmitter (5) by using the existing S-type ground element (4) as it is, and to share the information. It is also possible to use.

When a separate information transmission means is used, AT
A transponder or the like used in the S-SP type can be used, and in this case, line segment information such as an installation point can be transmitted together with the display information. The information transmitter (5) shall be installed at a position where the required braking distance can be secured from the maximum speed to the speed indicated by the corresponding caution signal.

On the other hand, the on-board security processing unit (CP) is installed on the vehicle which runs at high speed, and from high speed to stop depending on the progress information, caution information and stop information transmitted from the information transmitter (5). Is responsible for security control.

The on-board security processing unit (CP) is a position detection unit (1).
3), line segment data (14) and logic control section (15). At the time of receiving the progress information, the logic control unit (15) specifies the section from the reception point to the next information transmitter (5) from the line segment data (14), and enables traveling at the maximum speed to that point. On the other hand, when receiving the warning information, the warning signal is given to the crew and the deceleration pattern (16) from the maximum speed to the corresponding traffic signal is generated to continuously check the traveling speed and the pattern speed to exceed the speed limit. Prevent.

Further, when the stop information is received, a stop pattern (17) up to the corresponding traffic signal is generated, and the traveling speed and the pattern speed are continuously checked to prevent advance of the stop signal.

[0024]

As described above, according to the present invention, based on the existing color light traffic signal, the shortage of the braking distance caused by the speed improvement is compensated by giving the caution notice advance notice information to the crew, and the frame of the current signal system is provided. Enables speed improvement within.

Since the information transmission equipment required for that purpose uses the control conditions of the existing ATS-S type line and color light signal, it can be realized with a low construction cost and has an effect on improving the speed of the conventional line. Immense.
