Description

[0001] The present invention relates to a method for switching a level from an ATP mode to an ATC mode,

The present invention relates to a method for converting a level from an ATP mode to an ATC mode and a high speed railway vehicle, and more particularly, to a high speed railway vehicle, The present invention relates to a method for directly transferring information from an ATP to an ATC by transmitting information 44 of STM data defined by the present invention.

In general, there are ATS (Automatic Train Stop), ATP (Automatic Train Protection) and ATC (Automatic Train Control) for the safe operation of railway vehicles.

The ATS device is a device that decelerates or brakes the speed of the train automatically to prevent collision with the preceding train when the speed exceeds the speed limit of the signal.

The ATP device is a device that automatically receives the information necessary for train operation by using Balison which is installed on the track and automatically controls the speed of the following train according to the position of the preceding train. The signal system can be switched to an on-board signaling system by using a ground signal or by leaving it as it is.

The ATC device transmits the information on the ground by using the track detection circuit and the information transmission device, and displays the allowable speed continuously in the vehicle. When the speed of the train exceeds the allowable speed, It is a device that decelerates to a stop or permissible speed. It adds auto-acceleration function, fixed stop, door opening and closing, etc. to ATP function and applies to KTX, a high-speed railway vehicle.

Generally, automatic control devices such as ATS, ATC, and ATP are sequentially developed in accordance with the development of train control technology in the railway sections of domestic and foreign railroad, and they are installed in the railway and the vehicles. The control device is distributed and installed according to the situation or condition.

Accordingly, in order to operate a boundary section of a line in which an automatic control device of a different signal system is installed, first of all, a right of movement of the ground device of the corresponding automatic control device is performed, .

That is, two or more types of on-vehicle signal devices are installed in the railway vehicle, and the corresponding level is switched in the boundary section to be operated.

For example, when a high-speed ATC device section is operated in a conventional ATP device section, the level shift from ATP to ATC should be performed in the boundary section. In the conventional high-speed railway vehicle, ATP-> The ATS -> ATC switch is used to enable the ATS in the middle.

More specifically, the ATP-> ATC level conversion of the existing high-speed railway vehicle is performed through an Announcement Balance 22 installed on the ground line 2 as shown in FIGS. 1 and 2, The ATC mode is switched from the boundary at which the terminal 24 is encountered.

At this time, in order to change the level to ATC (Level Transition), it is defined to use NID_STM, which is information of Packet # 41 in Table 1 defined in ERTMS.

The European Railway Traffic Management System (ERTMS) is a European railway traffic management system that integrates and standardizes different signal systems in Europe with the European Train Control System (ETCS) to ensure interoperability, , Which was established as a European standard in the beginning, but it is now an international standard. It is also applying ERTMS / ETCS in non-European countries such as China, Russia, and Korea.

Also, the STM (Specific Transmission Module) is a system required for the ERTMS non-compliant route in the transition from the ATP system to the ERTMS.

Although the NID_STM variable is defined as a variable having unique characteristics for each STM, the present terrestrial system is composed of two systems, ATS and ATC, When receiving level switching information from ATP, it can not be discriminated whether the switch is to ATS or ATC.

Therefore, the ATP-> ATC level switching method applied to the existing high-speed railway vehicle can not be directly switched to the ATC mode used in the high-speed STM section in the ERTMS section, The ATS mode is activated according to the position of the ITL (Intermittent Transmission Loop, discontinuous information transmission loop) through the antenna 14, -> ATS -> ATC, or manual switching to ATC after ATP - ATS conversion as shown in FIG. 2.

Here, ITL is a device that transmits discontinuity information to a vehicle and is a cable loop installed inside the orbit.

Reference numeral 12 denotes a vehicle interface, and reference numeral 16 denotes a screen device.

On the other hand, the domestic high-speed railway system is based on ERTMS-based ATP system which is used in the existing line section (0km / h ~ 230km / h), ATS system which is a conventional point control system, ATC (300km / h ) Systems are mixed.

For this reason, ETCS-based ATP system is used as a junkyoung system for the safe operation of existing trains and the operation efficiency of the current train, and ATC system based on TVM430 is used as a junkyoung system do.

At this time, in order to automatically switch the on-board system according to the ground system, the high-speed railway vehicle has the function of automatically switching the on-board system from ATP to ATC on entering the high-speed line section from the existing line section.

However, as described above, the system applied to the conventional high-speed railway vehicle utilizes the ATS system, which is a conventional point control system, instead of the direct conversion from ATP to ATC when entering the high speed section from the existing line (low speed line) -> ATC, which has the problem that ATS and ATC are activated at the same time.

3, the ground line 2 is provided with an escape lease 22 and an execution balis 24, and the vehicle 1 is provided with an antenna 14, a vehicle-mounted signal device 10, a screen device 16, and a vehicle interface 12 are provided.

Antenna 14 receives line information and train operating information from Balis (including the forecast balis and run balis).

That is, the antenna 14 is installed at the lower portion of the high-speed railway vehicle and transmits a power signal at a frequency of, for example, 27 MHz to the balises 22 and 24 when passing over the balises 22 and 24, The balisers 22 and 24 are operated to transmit operating information (Balise Telegram) necessary for a train stored therein, for example, at a frequency of 4.2 MHz.

For example, if the onboard signaling device 10 is ATP, the distance between the preceding train and the trailing train is maintained in the low-speed line section, which is the ERTMS management section, and if the train speed exceeds the limit speed, Stop.

If the onboard signaling device 10 is an ATC, the permissible speed is continuously displayed in the vehicle in the high speed section, which is the STM management section, and when the speed of the train exceeds the permissible speed, the train is automatically stopped or decelerated within the allowable speed In addition to the ATP function, the device also performs functions such as automatic acceleration, stopping at a fixed position, opening and closing the door.

The driver's display device 16 provides speed information, ground information and driving information to the driver of the driver.

4 is a flowchart illustrating a level switching method according to an embodiment of the present invention.

ETCS is converted to level according to European standard. Currently, STM is divided into two modes, ATS and ATC, so it can not distinguish two STM modes with standard packet information # 41.

Accordingly, in the present invention, when the level is switched from ATP to ATC using packet # 44 of Table 2, which is separately defined by the user, the user directly switches to the ATC mode without going through the ATS mode.

Packet Number 44 (Packet Number 44) in Table 2 is data that can be defined separately by the user (ERTMS / ETCS system).

The data value of NID_XUSER is set to 102 or a separate value not used in the ERTMS, and a separate telegram (STM ID, STM for high speed line (TVM) Data) is recorded in advance in the preview lease 22 (S402).

At this time, the value of the STM ID means, for example, 14, the transition to the ATC, and the value of the STM data for the high-speed line means, for example, 69206020 and 69206024.

When the high-speed railway vehicle passes through the upper portion of the pre-lease 22 using the information of the next packet 41 and the packet 44, the pre-lease 22 transmits the STM to the on-vehicle signaling device 10 through the antenna 14 Information indicating that switching is to be performed is transmitted, and information of switching to ATC mode in STM 44 is transmitted (S404).

When the high-speed railway vehicle reaches the level switching position using the packet 41 and 44 information, the onboard signaling apparatus 10 executes STM to directly switch the level from ATP to ATC.

Although the preferred embodiments of the present invention have been disclosed for illustrative purposes, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims. In addition, it is a matter of course that various modifications and variations are possible without departing from the scope of the technical idea of the present invention by anyone having ordinary skill in the art.
