Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a railway track protection system,

The present invention relates to a system and method for operating a railway line protection zone, and more particularly, to a system and a method for operating a railway line protection zone, in which a position of a line worker is identified using communication between a mobile device owned by an operator and a ground AP installed on a railway line, The present invention relates to a system and a method for stopping a train before entering or slowing down a train by setting a protected area.

Train operations are based on running the train in a safe, accurate, and fast manner and by increasing the transport efficiency.

As a result, trains achieve the purpose of their operation with the aid of defined routes, fixed time between stations, signaling devices, line switching devices, track circuits, interlocks and crossing security devices.

However, since many trains operate in railways due to the necessity of new, supplementary and repairing of railway, electricity, and signal communication, delays in railway work are directly related to the delay of safe railway operation. I feel I am working on my work.

Accordingly, various methods are used in order to prevent safety accidents due to the train operation. For example, train operators who operate before the railway line are informed about and operate the work / time / work section, The train supervisor monitors the arrival of trains by arranging the train supervisor in front of the corresponding work section. The supervisor informs the workers when the train comes into view and avoids the safety zone. to be.

However, these primitive methods are dangerous, because train supervisors can not signal early enough to approach trains, which shortens the time workers have to escape to safety zones, It is very likely that a time error will lead to a fatal accident.

Particularly, when repair work is performed in front of and behind the curved section, not only the field of view is narrow, but when the geographical characteristics and work are enthusiastic, the driver can not hear the sound of the train horn, Frequently, the safety accidents that occur at this time lead directly to serious injury or death.

In addition, most of the line workers enter the work area after the verbal report by wireless, but they are not working due to the carelessness of the worker, the location of the worker due to mistakes, .

A number of prior art techniques have been disclosed to reduce the incidents of these line workers.

For example, Registration Practical Utility Model No. 20-0333423 relates to a proximity sensor for a railroad vehicle, which detects the approach of a vehicle when a repair work of a railroad track is performed and alerts workers to prevent damage to the railroad track. So that it can be prevented in advance.

A sensing device installed on a railway for sensing an approach of a train while maintaining a distance of 500 m to 1 km from the worker's work group and transmitting an approach detection signal to a user receiver in response to the approach detection; And a user receiver for receiving the approach detection signal from the sensing device and informing the operator of the received signal.

Patent No. 10-0968671 relates to an alarm system for informing the entry of a train or a worker in a curved section of a railroad track and is installed at both sides of a curved section of a railroad track and detects an entrance of a train and transmits a train entry signal Train entry detection device; A portable safety alarm device for receiving a train entry signal from a train entry detection device to generate an alarm, and periodically transmitting an operator entry signal; A worker entry detection device installed at both sides of the curved section of the railway line and receiving the worker entry signal from the portable safety alarm device and transmitting the worker entry signal; And a train alarm device installed in the train for receiving an operator entry signal from the worker entry detection device and generating an alarm.

However, these conventional prior patents are designed to detect the approach (entry) of a train and inform the operator of the approach by way of an alarm so as to prevent human accidents. There was still a danger that the accident could not be avoided.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

It is to be noted that the same components of the drawings are denoted by the same reference numerals and symbols as possible even if they are shown in different drawings.

In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear.

Also, when a part is referred to as "including " an element, it does not exclude other elements unless specifically stated otherwise.

1 is a view for explaining the concept of safe driving of a train using the guard interval of the present invention.

As shown in FIG. 1, a guard interval is set on a line before and after a traveling direction of a train in the position of an operator working for maintenance of the line 30. More specifically, A guard interval is set in the front and rear lines of the trains in the traveling direction of the ground AP 10, which is a line device.

The ground APs 10 are installed at predetermined intervals along the line and wirelessly communicate with the mobile device 20 of the operator. Each of the ground APs 10 is assigned a unique IP address, (40) or the central control unit of the control room.

The terrestrial ATC device 40 determines the location of the terrestrial IP 10 using the IP address of the terrestrial AP 10 wirelessly communicating with the mobile device 20 of the operator, And sets the protection zone on the line before and after the direction of the progress of the line.

Also, the terrestrial ATC device 40 sets a movement authority that does not invade the established guard interval, and notifies the train of the movement authority section.

The train 50 stops at the movement permission zone before the protection zone or enters the protection zone and then slowly moves according to the movement permission zone.

2 is a block diagram of a guard interval management system according to an embodiment of the present invention.

2, the guard interval setting system includes the ground AP 10, the mobile device 20, the ground ATC device 40, the on-vehicle signal device 52, the central control device 62, and the DCS device 70, .

The ground AP (10) installed at regular intervals along the line is a communication facility for providing continuous wireless communication between onboard signal devices (52) mounted on a train (50). It is a facility for train movement, monitoring and control.

The terrestrial AP 10 is assigned a unique IP address and receives information related to the position of a train to be transmitted in radio communication from the onboard signaling device 52 mounted on the train 50, To the ground ATC device (40) through the antenna (70).

The ground AP 10 continuously communicates wirelessly with the mobile device 20 possessed by the operator and transmits the result of wireless communication with the mobile device 20 via the DCS device 70 to the ground ATC device 40).

To this end, the mobile device 20 is provided with a simple program (AP transmission / reception application) capable of continuously pinging with the terrestrial AP 10 or allowing only minimum information to be periodically transmitted and received, (20) periodically wirelessly communicates with the terrestrial AP (10).

The DCS device 70 is configured to wirelessly communicate with a DCS (Data Communication System) network configured for a Radio Frequency-Communication Based Train Control (RF-CBTC) And the terrestrial ATC device 40 so that they can receive and transmit signals.

That is, the DCS device 70 receives the location-related information of the train and the wireless communication result with the mobile device from the terrestrial AP 10, transmits the result to the terrestrial ATC device 40, ) And transmits them together.

Further, it receives the train control signal from the central control unit 62 of the command room 60 or the ground ATC unit 40, and transmits it to the terrestrial AP 10.

The ground ATC device 40 is installed on the track side to transmit the terrestrial train running conditions to the onboard signal device 52 by using a track circuit or radio to indicate the allowable speed on the train and to set the train speed to exceed the allowable speed The train can be automatically stopped or allowed to decelerate to a permissible speed.

The ground ATC device 40 manages the safe distance between the preceding train and the following train on the basis of the position information of the train sent from the ground AP 10 to the wireless communication.

The terrestrial ATC device 40 detects the location of the terrestrial AP 10 with the IP address of the terrestrial AP 10, sets a guard interval in the line sections before and after the terrestrial AP 10 on the basis of the position of the terrestrial AP 10, 60 to the central control unit 62 of the base station.

The central control unit 62 real-time bi-directionally communicates with all the trains and ground facilities that are in operation to enable safe train operation using the RF-CBTC system and all the trains within the control zone. The ATC 62 of the train control system ) Function.

The central control unit 62 is installed in a command room 60 for remotely controlling the operation of the train so that the running state of the train transmitted from the terrestrial ATC apparatus 40 by the on- Information and vehicle fault information to the controller and transmits the train control signal inputted by the controller to the onboard signaling device 52 of the train via the terrestrial ATC device 40 and the ground AP 10 .

In particular, in the present invention, the guard interval transmitted from the terrestrial ATC apparatus 40 is received, and the guard interval is reset if necessary. The reconfigured protection section is displayed on the large display panel 64 provided in the command room and transmitted to the terrestrial ATC apparatus 40. [

For example, when an accident frequently occurs during work in the protection zone, the protection zone is widened more widely than the protection zone sent from the terrestrial ATC unit 40 to reduce the accident.

If there is a lot of trains to operate the protection zone without the occurrence of an accident while working in the protection zone, the guard zone is set to be narrower than the zone sent from the ground ATC unit 40 to minimize the delay of the train due to slowing of the guard zone .

If the central control unit 62 determines that it is not necessary to reset the guard interval, the central monitoring unit 62 displays the guard interval on the route map of the large display unit 64 provided in the command room 60.

The large display panel 64 is a device for displaying the train number and the train operation status. It is a device for the controller to monitor and control the train operation over the entire length of the main line. To be monitored.

On the other hand, the terrestrial ATC apparatus 40 transmits a protection zone to the central control unit 62, and then sets a movement authority zone that does not violate the protection zone set by itself or the protection zone reset by the central control unit 62 To the onboard signaling device of the train (50) via the ground AP (10).

The onboard signaling device 52 of the train 50 stops the train ahead of the guard interval or decelerates the train within the allowable speed in the guard interval according to the received movement authority interval and drives the train slowly within the guard interval.

At this time, in consideration of the importance of the maintenance work and the time required for the maintenance work, the controller of the command room inputs the signal to the central control unit 62 and transmits it to the terrestrial ATC apparatus 40 as a train control signal .

Of course, the terrestrial ATC device 40 transmits this fact to the onboard signaling device 52 when the train passes through the guard zone in the slow running mode, so that the terrestrial ATC device 40 can operate at normal speed thereafter.

On the other hand, when the operator performs the maintenance work while moving along the line (30). The ground AP 10 wirelessly communicating with the mobile device 20 owned by the operator is handed over from one ground AP to another ground AP so that the ground AP for wireless communication with the mobile device 20 is changed, As the IP address and location of the IP are changed, the guard interval is also automatically changed so that the guard interval can be set in real time according to the position of the operator to protect the operator from the train.

In addition, when the operator finishes the maintenance work and leaves the track, the mobile device 20 can not communicate with the mobile device 20 after leaving the sector of the ground AP 100, and the ground AP 20 DCS network to the terrestrial ATC device 40, the terrestrial ATC device 40 releases the preset guard interval, so that the train can normally operate.

3 is a flowchart of a method of operating a guard interval according to an embodiment of the present invention.

The worker installs an AP transmission / reception application in the mobile device 20 so that the mobile device 20 can periodically wirelessly communicate with the terrestrial AP 10 and transmits the AP transmission / reception application to the mobile device 20 (S302).

May be executed by a signal sent from the terrestrial AP 10 when the AP is input without executing the AP transmission / reception app.

In addition, the AP transmission / reception app may have a function of allowing a ping test to be continuously performed with the terrestrial AP 10 or transmitting / receiving only minimum information periodically.

As the operator enters the maintenance work of the line while holding the mobile device 20 and the AP transmission / reception app is executed, the mobile device 20 and the ground AP 10 adjacent to the mobile device 20 periodically The ground AP 10 wirelessly communicating with the mobile device 20 notifies the DCS device 70 of the wireless communication with the mobile device 20 through wireless communication at step S304.

The DCS device 70 confirms the IP address uniquely assigned to the terrestrial AP 10 and transmits it to the terrestrial ATC device 40 (S306).

The terrestrial ATC device 40 detects the location of the terrestrial AP 10 with the IP address of the terrestrial AP 10 and sets a guard interval for a predetermined distance in the front and back lines of the terrestrial AP location, To the central control unit 62 (S308).

The central control unit 62 of the control room 60 determines whether to reset the guard interval according to the state of the line 30 after receiving the guard interval at step S310.

The guard interval is re-established in such a manner that the received guard interval is widened or narrowed according to the state of the line, and the guard interval is notified to the ground ATC device 40 at step S312.

The central control unit 62 displays the reset protection zone on the route map of the large display unit 64 provided in the command room 60 or when it determines that the protection zone is not to be reset, The guard interval is displayed on the large display panel 64 route map (S314).

In the next terrestrial ATC device 40, if there is a guard interval set by itself or a guard interval notification reset from the central control unit 62, a movement authority section that does not violate the reset guard section is set and a movement authority section is set To the onboard signaling device 52 of the oncoming train 50 through the terrestrial AP 10 (S316).

The onboard signaling device 52 stops at a point before the end of the movement authority section, that is, before the end of the protection section, or enters the protection section, and performs the slow motion while paying attention to the operator in the protection section ).

In the above description, the case where the operator carries the mobile device 20 and puts the mobile device 20 into line maintenance work has been described as an example. However, the motor vehicle may be mounted on a motor car which is a self- Even when the worker carries out the work, the position of the motor car can be grasped by the general control device 62 of the control room, and the guard interval can be set and safe work can be induced.

As described above, according to the present invention, as an equipment capable of enhancing safety in a section of an urban railway where a RF-CBTC system is operated using a mobile device, first, as an alternative to an expensive ATC on- Second, it is possible to secure the safety of the motorcycle operating section. Second, it is possible to easily track the position of the field workers and the position of the moving train, so that the safety of the worker can be secured Third, it is possible to prevent the risk of accidents due to the location of work that is reported incorrectly due to mistakes or errors of field workers.
