The present invention is to remotely control the speed limit of the train automatic grounding device to safely control the train operating speed value output for each track from the ATC ground device 20 in case of emergency, which can only be manually adjusted in the SLP (10). It relates to a control system.

In general, a tracker is provided on the track side through which the railroad car passes to inform the engineer of the speed of the train that can run in the forward track section. However, unlike ordinary trains operating at 150 km / h, high-speed trains operate at a high speed of 300 km / h, so the engineer cannot see and drive the signal in front of the naked eye.

Therefore, the speed information suitable for the train operation according to the general conditions of the track, such as the position of the preceding train, the driving route and the curve, is transmitted to the vehicle and displayed in the cab of the train, and the operating speed of the train exceeds the allowable speed. The ATC system that automatically controls the braking system of the train is installed inside the train and on the track side of the ground.

The ATC device is largely installed on the track side of the ground to generate speed signal information suitable for the train operating conditions for each occlusion section, and modulates the frequency corresponding to the speed, and transmits it to the track circuit of the field track and the loop cable. 20 and the speed information received from the ATC ground apparatus 20 is displayed in the cab and is automatically classified as an ATC on-vehicle apparatus that operates the braking system when the train exceeds the allowable speed.

Herein, the present invention relates to the ATC ground apparatus 20 among the ATC apparatuses.

On the other hand, high-speed trains operating at speeds of 300 km / h or more will lead to large-scale accidents if they do not respond immediately when an obstacle or emergency occurs, rather than a planned situation. Therefore, in preparation for this, in the signal relay room of all stations, the SLP 10 for limiting the train operating speed output to the ATC ground apparatus 20 to 170 km / h or 90 km / h in case of emergency is ATC above ground. It is connected to the device 20 and used.

Herein, the configuration of the conventional ATC ground apparatus 20 and the SLP 10 will be described with reference to FIGS. 1 and 2.

1 is a system block diagram for the manual operation of the conventional ATC ground apparatus 20, Figure 2 is a view showing a connection diagram of the ATC ground apparatus 20 and the SLP (10).

First, referring to FIG. 1, a plurality of ON / OFF switches for limiting the speeds of tracks by occlusion sections to 170 km / h and 90 km / h are disposed on a panel, and each switch input is input to the ATC ground apparatus 20. An SLP 10 for outputting; An ATC ground apparatus (20) connected to the SLP (10) and an interlocking device (not shown) in a field station signal machine room to generate speed signal information suitable for operating conditions for each occlusion section and to transmit the information for each track; It consists of a track for flowing the signal current output from the ATC ground device 20 to the railway track.

Here, the ATC terrestrial device 20 normally receives and processes an interlocking processing condition from the interlocking device. When a signal is input from the SLP 10, the ATC ground apparatus 20 processes the input of the SLP 10 without processing the input of the interlocking device. This is to prepare for the case where the high speed railway signal control system is operated by automation, so it is urgent to reduce the speed.

Next, referring to the connection diagram of the ATC ground apparatus 20 and the SLP 10 with reference to FIG. 2, the SLP 10 has two switches (170 km / h and 90 km / h) per track and each switch. The circuit is connected to the ATC ground device 20 in a 1: 1. Here, when all the switches of the SLP 10 are in the ON state, the ATC ground apparatus 20 outputs at a normal driving speed of 300 km / h, processes an input signal from an interlocking apparatus, and any one of the SLPs 10. When the switch (170 km / h, 90 km / h) is in the OFF state, the ATC ground apparatus 20 outputs an OFF speed (any one of 170 km / h 90 km / h).

Referring to the operation of the ATC ground apparatus 20 configured as described above, the ATC ground apparatus 20 normally outputs the speed signal information for each track in accordance with the interlocking processing conditions transmitted from the interlocking device and repairs the track side. If an emergency situation arises, the serviceman immediately goes to the signal relay room and checks the corresponding track section in the SLP (10) and changes the switch of the speed (170km / h or 90km / h) to limit the related track from ON to OFF. do. Then, the ATC ground apparatus 20 changes the speed signal information of the track to an OFF speed value of the SLP 10 (any one of 170 km / h, 90 km / h) and outputs it to the track circuit. After that, the maintainer turns on the OFF switch of the SLP 10 in order to return to normal driving speed again.

In this case, the control command of the SLP 10 is processed prior to the control command of the interlocking device, so that the output of the ATC ground device 20 is fixed to the output signal of the SLP 10 until the maintenance worker returns. In this case, the track section cannot operate at the maximum speed of 300 km / h, which is the highest speed of the high-speed railway, and the train speed of the entire railway section decreases in series. Therefore, the work of restoring the switch of the SLP 10 that is turned off is also an important work that should not be missed.

Meanwhile, as mentioned above, the SLP 10 currently in use allows the repairer to directly change the ATC ground apparatus 20 in an emergency situation. In this case, the SLP 10 must be manually controlled. Therefore, the repairman should go to the signal relay room of the site station where the SLP 10 is installed and operate it directly.

However, in the case of high-speed railways currently in operation, all devices including interlocks are automated systems, so driver operators and maintenance workers do not reside in the signal relay room in all stations, and only some stations operate to manage the remaining multiple stations.

In fact, among the 19 signaling machine rooms between Gwangmyeong Station and Daegu Station, the driver handles only the Gwangmyeong Station, Cheonan Station, and Yeongdong Station, and manages the remaining stations. There is a situation.

As a result, if a conservative arrives a little late at the station, there is a problem that immediately leads to a large accident. In addition, when an emergency situation is handled and normal operation is possible, there is a problem that a maintenance worker must wait in the corresponding station until the OFF switch of the SLP 10 needs to be operated again.

In addition, when the control handling is carried out in sequence while moving the signal machine room of a large number of stations, it takes a long time to move, and since the handled SLP 10 must be returned in sequence, the delay time increases until the normal operation occurs once an unexpected failure occurs. There is a problem.

As a result, the delayed time also interferes with other train operation times on the entire railway, which leads to inconveniences and distrust of customers, and increases the amount of business damage compared to the delayed time. There is a problem that also brings inefficient work effects to the payers.

Therefore, alternatives must be made to safely and accurately control the ATC ground apparatus 20 remotely.

The present invention has been made to solve the conventional problems as described above, it is an object of the ATC terrestrial device 20 to be able to control the remote from the convenient control handling and to make the train safe and fast operation. .

Another object of the present invention is to make it possible to control the ATC ground apparatus 20 of each station not only in the management station where the maintainer resides but also in the command control room that controls and supervises the entire section of the high-speed railway.

Another object of the present invention is to allow the existing SLP 10 and the remote control system to operate separately so that the impact of the failure of the remote control system does not affect the SLP 10 and the ATC ground apparatus 20. For the purpose of construction.

Another object of the present invention is that all devices that control the ATC terrestrial device 20 has a self-diagnostic function to detect the failure by periodic self-diagnosis, and to operate in the existing SLP (10) when a failure occurs For the purpose of

It describes the operation process of the present invention configured as described above.

First, since the currently operating ATC ground apparatus 20 processes the control commands of the SLP 10 first, in order to correctly use the remote control system of the present invention, 170 km / h and 90 km of all tracks output from the SLP 10 are used. Keep the / h switch on. In addition, the field control device 400 outputs 170 km / h and 90 km / h of all tracks in an ON state.

On the other hand, the input module 440 detects the output information of the SLP 10 and the field control device 400 and transmits to the reverse control device 320 through the modem 410, the reverse control device 320 Outputs the information received from all stations having jurisdiction and its operation state information to the command control device 310 and then displays the changed information on the monitor 322 screen, and the command control device 310 controls the station control device. Displays the output information of the SLP 10 and the site control device 400 and the operation state of the reverse control device 320 of the entire railway section received from the (320).

Then, when there is a need for limiting the train operating speed of the track section to 170km / h due to an unexpected obstacle in the track section, the driver of the command room limits the speed of the track section to 170km / h through the terminal device while watching the screen. When the command terminal device 313 generates a control command and transmits the control command to the reverse control device 320 through the modem 311, the control command is transmitted through the terminal of the reverse control device 320. Transmitted to the central processing unit 420 of the control unit 400, and the central processing unit 420 processes the control command and turns OFF to the 170 km / h port of the corresponding track in the output module 430 to the 90 km / h port. Output ON. Subsequently, the ATC ground apparatus 20 outputs a frequency corresponding to 170 km / h to the track circuit.

And the driver of the command room can handle the command to control the ATC ground apparatus 20 of a plurality of stations as needed, and can handle the command to return the handled signal again.

In addition, the driver of the management station can handle the same control as the driver of the command room. In this case, the driver handles the control through the management station terminal device 323 of the station control device 320. In the same manner as the process is processed by the central processing unit 420 of the field control device 400 through the modem 321, the ATC ground apparatus 20 outputs a frequency corresponding to the limited speed to the track circuit.

On the other hand, each terminal device (313, 323) of the command control device 310 and the reverse control device 320 is self-checking, if a failure occurs in its own equipment to switch directly to another emergency device, the monitor (312, 322) screen In particular, the station control device 320 transmits the status information of the currently operating equipment to the command terminal device 313 in real time, and the command terminal device 313 is installed in each field station together with the command room equipment. Displays the status of on the screen.

In addition, the central processing unit 420 of the field control device 400 self-examines, and if a failure occurs in its own equipment, deactivates the operation limiting relay 460 to maintain the last output signal of the output module 430, and the ATC ground device ( 20) output signal of the output module 430 is not transmitted.

Thereafter, when the central processing unit 420 transmits the failure occurrence information to the reverse control unit 320 and the command control unit 310, the reverse control unit 320 and the command control unit 310 detect a failure to the driver. When the driver handles the maintenance of the field control device 400 after checking, the operation limit relay 460 is excited and the output signal of the output module 430 is outputted to the ATC ground device 20 again.
