Referring to FIG. 1, an apparatus for preventing a train accident according to an embodiment of the present invention includes a train monitor 10 and a remote controller 20.

The train monitor 10 is installed to be movable along the line R and moves back and forth along the line R in accordance with a movement control signal from the remote controller 20. [

The train monitor 10 moves to the warning point in accordance with the movement control signal from the remote controller 20 and senses the train T at the warning point and informs the engineer of the train T on the line And transmits the train access information to the remote controller 20 so that the remote controller 20 warns the operator that the train T is being accessed. That is, the train supervisor 10 warns the trainee of the train T or the worker at the work site in accordance with whether or not the train is detected.

Here, the warning point is a position on the line R of the train monitor 10 for detecting the train T, and may be set at a predetermined distance around the work area, or may be arbitrarily determined through remote control of the operator . For example, the warning point may be preset at a distance of 300 to 500 meters from the work section, and may be appropriately set by the operator in consideration of whether or not the workpiece is bent or the line T is bent.

For example, the train supervisor 10 warns the trainee of the train T that the train T is working, even if the train T is a relatively long distance from the warning point, that is, the train T is not detected. Thus, the engineer of the train (T) can recognize that the line is still being operated on a relatively long distance from the warning point. In this case, the train supervisor 10 blinks light or displays letters or symbols so that the trains of the train T can be seen even at a distance from the engine.

When the train T is relatively close and the train T is detected, that is, when the train T collides with the train T or the position of the train T is detected, And warns that it is working on the track. In this case, the train monitor 10 outputs a warning sound to the extent that the engine of the train T can hear, for example, an explosion sound at a setting level or higher. In addition, according to the explosion sound, the operator in the front is aware that the train T is approaching.

When the train T is detected, the train supervisor 10 transmits the train access information to the remote controller 20 so that the remote controller 20 warns the operator that the train T is being accessed do.

The remote controller 20 is connected to the train supervisor 10 by wire or wireless and transmits a movement control signal to the train supervisor 10 to control the movement of the train supervisor 10. Therefore, the operator can operate the remote controller 20 to move the train monitor 10 to a desired warning point or move it to a predetermined warning point.

When the train access information is transmitted from the train monitor 10, the remote controller 20 warns the operator that the train T is being accessed according to the train access information. In this case, the remote controller 20 warns that the train T is approaching through a warning sound, a character or an image, and the operator can recognize that the train T is approaching and cope with it.

2 and 3, the train monitor 10 includes a moving unit 11, a distance measuring unit 12, a train sensing unit 13, a first warning unit 14, a second warning unit 15, And a monitor controller 16.

The moving unit 11 moves the main body of the train monitor 10 along the line R. The moving unit 11 includes four wheels FL, FR, RL and RR 112 rotating on the line R and a driving unit 111 for rotating the wheels 112.

The monitor control unit 16 controls the driving unit 111 to rotate the wheel 12 forward or backward to move the train monitor 10 forward or backward.

The wheels 112 are made to have a height that makes contact with the rear end of the train T so as not to interfere with the operation of the train T when colliding with the train T. [

Furthermore, the wheels 112 are separately manufactured from the main body of the train supervisor 10, so that the wheels 112 can be reused even when the train supervisor 10 and the train T collide.

The distance measuring unit 12 measures the distance from the work section to the warning point. When the train monitor 10 starts to move from the work section, the distance measuring section 12 determines whether the current state of the train 10 is moving forward or backward based on the operation state of the drive section 111 or the control signal of the monitor control section 16 And the distance from the work section to the warning point is accurately measured by increasing or decreasing the travel distance according to the confirmation result.

That is, the distance measuring unit 12 cumulatively sums the travel distance when the train monitor 10 moves forward and the travel distance when it moves backward, and moves backward from the cumulative distance accumulated when moving forward By subtracting the accumulated summed distance, the distance from the work section to the warning point is accurately measured.

The train sensing unit 13 senses the train T and includes a collision sensing unit 131 and a proximity sensor 132.

The collision sensing unit 131 senses a collision with the train T. [

The collision sensing unit 131 may be an impact sensor that senses an amount of impact with the train T or a collision sensing switch that operates with the impact when the vehicle collides with the train T. [

The collision detection switch operates due to the collision with the train T as shown in FIG. 4, so that the train detection error can be minimized and the reliability of train detection can be ensured.

On the other hand, when the impact sensor is used as the collision sensing unit 131, it can be determined that the collision with the train T occurs if the sensed impact amount is equal to or greater than the set impact amount.

The proximity sensor 132 senses the distance to the train T as shown in Figure 5. In this case, the proximity sensor 132 detects the distance to the train T when the train T approaches within the detectable distance can do.

The first warning unit 14 warns the engineer of the train T that the railway is in operation. The first warning unit 14 continuously operates irrespective of the train detection. That is, when the train supervisor 10 arrives at the warning point, the first warning unit 14 starts operation in accordance with the control signal of the supervisor control unit 16. When the train T is at a relatively long distance from the warning point Even if the train T is not detected by the train sensing unit 13, the light is blinked or characters or symbols are displayed. Therefore, the engineer of the train (T) can recognize that the line is being worked on from the front even at a relatively far distance from the warning point.

The second warning unit 15 warns the engineer of the train T that the railway is in operation. The second warning unit 15 operates when the train T is detected by the train detection unit 13. That is, when the collision sensing unit 131 detects a train collision or the proximity sensor 132 detects the distance to the train T, the second warning unit 15 outputs the control signal of the monitor control unit 16 The second warning unit 15 is controlled to generate an explosion sound so that the engine driver of the train T can recognize that the current line is being operated on the front side and the worker at the work site hears the explosion sound, So that the user can recognize that the user is in the vicinity.

The monitor control unit 16 controls the moving unit 11 according to the movement control signal when the movement control signal is transmitted through the wired or wireless communication from the remote controller 20 so that the train monitor 10 moves along the line R do. In this case, the supervisory controller 16 can move the train supervisor 10 by a predetermined set distance in accordance with the movement control signal.

In this process, the distance measuring unit 12 measures the distance through the driving unit 111 and inputs the measured distance to the monitor controller 16.

The monitor control unit 16 transfers the distance measured by the distance measuring unit 12 to the remote controller 20 through wired / wireless communication.

On the other hand, the monitor control unit 16 controls the first warning unit 14 in response to the operation start signal transmitted from the remote controller 20 when it reaches the warning point, thereby blinking light or expressing a character or symbol, (T) to the engineer of the current line.

The train sensing unit 13 senses a collision with the train T and the position of the train T. The monitor control unit 16 controls the second warning unit 15).

The second warning unit 15 generates an explosion sound in response to the control signal from the monitor control unit 16 to warn the engineer of the train T that the railway is currently working in front of the train, Is in close proximity.

Further, when the train T is sensed by the train sensing unit 13 as described above, the monitor control unit 16 transmits the train access information to the remote controller 20.

In this case, the remote controller 20 warns the operator of approaching the train T based on the train access information.

6, the remote controller 20 transmits a movement control signal to the train supervisor 10 according to the operation of the operator to move the train supervisor 10 to a warning point, and transmits an operation start signal to the train supervisor 10, To operate the train monitor 10, and receives the train access information from the train monitor 10 to alert the access of the train T.

The remote controller 20 includes an operation unit 21, an output unit 22, and a remote control unit 23.

The operation unit 21 receives an operator's control command for operating the train monitor 10, and inputs the control command to the remote control unit 23. The operation unit 21 includes a lever for moving the train monitor 10 forward and backward, an operation status display button for displaying the operation status of the train monitor 10, and an operation button for starting the operation of the train monitor 10 May be included.

The output unit 22 warns the operator that the train T is approaching by outputting a warning sound or outputting a character or a symbol or the like so that the operation state of the train monitor 10, for example, the position of the train monitor 10, Distance, and so on.

The remote control unit 23 transmits a movement control signal corresponding to the control command to the train monitor 10 when a control command for moving the train monitor 10 is inputted from the operation unit 21. [

The remote control unit 23 transmits an operation start signal to the train monitor 10 when a control command for operating the train monitor 10 is input from the operation unit 21. [

Thereafter, when the train access information is transmitted from the train supervisor 10, the remote control unit 23 controls the output unit 22 according to the train access information to output a warning sound, or output characters or symbols, T).

In addition, the remote control unit 23 receives the operation status, for example, the distance that the train monitor 10 has moved from the train monitor 10 in the above process, and outputs the received distance through the output unit 22.

Hereinafter, an operation process of the train accident prevention apparatus according to an embodiment of the present invention will be described.

First, when a control command for moving the train monitor 10 is input, the remote controller 20 transmits a movement control signal to the train monitor 10 according to the control command.

When the movement control signal is transmitted from the remote controller 20 in a state where the train supervisor 10 is positioned on the line R, the train supervisor 10 moves along the line R according to the movement control signal.

At this time, the train monitor 10 measures the distance traveled along the line R and transmits the measured distance to the remote controller 20 through wired / wireless communication.

The remote controller 20 outputs the distance traveled by the train monitor 10 so that the operator can recognize the position of the train monitor 10 and the distance from the work area.

On the other hand, as the train supervisor 10 moves along the line R to arrive at the warning point, the operator operates the remote controller 20 to operate the train supervisor 10.

The remote controller 20 transmits an operation start signal to the train monitor 10 and the train monitor 10 starts operation according to the operation start signal transmitted from the remote controller 20.

In this case, the train supervisory controller 10 can control the operation of the train T even if the train T is not detected due to the fact that the train T is located at a relatively long distance by blinking light, You can warn your engineer that you are working on the track.

Normally, an engineer of a train T who is aware of the current line operation will stop the train T in an emergency. However, if the visibility can not be secured due to the influence of the weather or the like, the engineer may not be fully aware of the warning from the train monitor 10.

In this case, since the engineer will not stop the train T, the distance between the train T and the train supervisor 10 may approach, or the train T and the train supervisor 10 may collide with each other.

Thus, when the train supervisor 10 detects a collision with the train T or the position of the train T, an explosion sound is generated, thereby alerting the engineer of the train T to the fact that the train is currently working in front of the train, Warns that train (T) is approaching.

Further, when the train T is detected, the train monitor 10 transmits the train access information to the remote controller 20 as described above.

Accordingly, the remote controller 20 outputs a warning sound or outputs characters or symbols based on the train access information, thereby alerting the operator that the train T is being accessed.

As described above, the train accident prevention device according to the embodiment of the present invention is installed so as to be remotely movable along the line R along the front and rear of the work section, detects the train T, Or train access, respectively, to prevent train accidents, and to improve the reliability of railway accident prevention by guiding train operators to railway operations and guiding trains to workers.

The apparatus for preventing a train accident according to an embodiment of the present invention can prevent train accidents in a high-speed railway, a general railway and an urban railway irrespective of the types and characteristics of the railway R and the train T.

In addition, the train accident prevention device according to the embodiment of the present invention can minimize the train detection error by warning based on the collision with the train T.

In addition, the train accident prevention device according to the embodiment of the present invention moves remotely along the line R to sense the train T, thereby eliminating the need for the operator to directly walk along the corresponding section, There is no need to deploy personnel for surveillance, which reduces labor costs and improves practicality.
