FIG. 1 is a conceptual diagram illustrating a light emitting diode (LED) signal transmitter of a five-state type according to an embodiment of the present invention.

Referring to FIG. 1, a light emitting diode (LED) signal device having a five-level display may be implemented based on two LEDs or the like. The two LEDs and the like may be combined with each other to emit light of five different colors.

When two LEDs or the like are referred to as a first LED or the like or a second LED or the like, five signals can be displayed using the first LED, the second LED, or the like. The five signals may be the progress signal 100, the deceleration signal 110, the attention signal 120, the boundary signal 130, and the stop signal 140. Hereinafter, the combination of the first LED and the second LED used to represent the five signals according to the embodiment of the present invention is arbitrary and may represent five signals based on combinations of other LEDs and the like. For example, five signals can be expressed using the first LED, the second LED, and the like in the following combination.

A progress signal 100 indicating that the first LED or the like is off and the second LED or the like is a green light G indicates that the train may continue to run.

If the first LED or the like is a yellow light Y and the second LED or the like is a green light G, the deceleration signal 110 for decelerating the speed of the train may be displayed.

If the first LED or the like is a yellow light Y and the second LED or the like is off, it may indicate a caution signal 120, which is a signal to note the preceding train.

If the first LED or the like is a yellow light Y and the second LED or the like is a yellow light Y, it may indicate a boundary signal 130 to alert the preceding train.

If the first LED or the like is off and the second LED or the like is red (R), it may indicate a stop signal 140 to stop the train.

According to the embodiment of the present invention, the light emitting diode (LED) signal of the five-state type can display five kinds of signals based on the two LEDs included.

The five-LED indicator light can change colors based on train location information. The LED light signal of the 5-state LED light can use information on whether or not the track circuit is short-circuited according to the train's operation in order to change the signal information to be displayed. As described later, when a railway circuit is short-circuited by the wheels of a train, the light emitting diode (LED) of the light emitting diode (LED) emits light of a second light emitting diode (LED) .

If one of the five LED 5 LEDs is changed to a stop signal, the other 5 LEDs in the traverse direction of the train due to the relay interlocks sequentially indicate the boundary signal, attention signal, deceleration signal, and progress signal. Signal.

For example, it can be assumed that an LED 5-state LED signal on the track side is implemented at intervals of 100 m. In this case, the light-emitting diode 5-LED indicator present at the previous 100m relative to the light-emitting diode 5-LED indicator changed to the stop signal is present at the boundary signal, The 5-LED indicator is an accelerator signal, and the 5-LED indicator is a progressive signal. By using this method, a train can judge whether trains exist in front of 100m, 200m, 300m or 400m in the direction of travel.

FIG. 2 is a conceptual diagram illustrating an LED display of an equal-type 5-state LED installed on a line according to an embodiment of the present invention.

FIG. 2 shows the first LED 5, the second LED 5, the second LED 5, and the second LED 5, Type five LED indicator 240, and a fifth five-LED indicator 250. FIG.

Assuming that the quadrature five-LED signal set on the line has a constant signal interval (e.g., 100 m), the second quadrature five-phase LED signal 220 is pre- The signaling unit may be located at a position spaced apart by the signaling device interval. The third tri-state 5-LED signal 230 may be a signal located at a distance from the second tri-state 5-state LED signal 220 by a signal interval. The fourth quadrant 5-present LED signal 240 may be a signal located at a distance of the signal interval prior to the third quadrant 5-state LED signal 230. The fifth twin LED indicator 250 may be a signal located at a distance from the fourth twin LED indicator 240,

Referring to FIG. 2, when the train 200 enters a specific position based on the position of the first LED 5 for the first 5-state display 210, the track circuit formed by the line and the closed loop may be short- have. When the track circuit is short-circuited, the first and second 5-state LED signalers 210 can display a stop signal (a first LED, such as an off, a second LED, or the like, a red signal).

When the first LED 5 is turned on, the second LED 5 emits light sequentially in the forward direction of the train by the interlocking of the relays. Such as a yellow signal, a second LED, etc., a yellow signal). In addition, the third triode 5-LED signal generator 230 receives the attention signal (the first LED, such as the yellow LED, the second LED, and so on) The first LED 5, the second LED 5, etc. The LED indicator 250 can be displayed as a progress signal (a first LED, such as a green signal, a second LED, a green signal) have.

Figure 3 discloses the operation of a train when a two-state 5 LED indicator is broken in accordance with an embodiment of the present invention.

FIG. 3 illustrates the signaling scheme of a quadrature five-state LED signaler when a first LED or a second LED implemented in a five-state LED signaler fails.

Referring to FIG. 3, it can be assumed that the LED signal of one of the first LED 300 and the second LED 350, which is implemented in the LED display device of a quadrature 5-state, fails. For example, in the case of a deceleration signal, the first LED 300 may have a yellow signal and the second LED 350 may have a green signal. If the first LED 300 fails, the deceleration signal may indicate a deceleration signal by changing the second LED 350 to a green flashing light or a yellow signal and using an alternative signal. Alternate signals used in the event of a malfunctioning 5-LED LED signal must be a signal that is not the same as another signaling system. By using this method, the train can obtain a deceleration signal based on the second LED 350, which is another LED that has not failed even when the first LED 300 fails. As another example, if the second LED 350 fails, the first LED 300 may be changed to flash or the first LED 300 may be changed to green to indicate a deceleration signal.

Information about the change in the signaling scheme of the light-emitting diode (LED) signal device of the present invention may be transmitted to the train so that the train operator who operates the train can recognize the signal of the signaling device based on the changed signaling system. For example, if there is a signal controller controlling a light-emitting diode (LED) signaling device implemented on the line, the signaling controller may transmit a signaling change signal to the train indicating that the signaling system has changed due to a current LED signal failure. The operator of the train receiving the signal change signal can control the driving of the train based on the changed signaling system when the train is operated.

Figure 4 discloses the operation of a train in the event of a malfunctioning five-state LED signaling device in accordance with an embodiment of the present invention.

FIG. 4 illustrates a method of controlling a train through additional judgment when a lighted five-state LED signaling device fails. In case of a malfunction of the light-emitting diode (LED) 5 signal, the train is unable to provide information on the position of the preceding train, so the train needs to perform an additional position determination of the preceding train.

First, the first five-mode LED signal 410 to the fifth five-mode LED signal 450 are implemented on the line at a predetermined interval, and the fourth five-mode LED signal 440 is broken Can be assumed. For example, failure of a five-state LED signaling device may be detected by determining whether the current five-state LED signaling device emits light through a light emitting sensor implemented in the five-state LED signaling device.

In this case, because the fourth quadrangle 5-state LED signal 440 is out of order, the train can not see the caution signal in the fourth quadrangle 5-state LED signal 440 and the fifth quadrature 5-state LED signal 450 It is possible to see the stop signal through the switch. In this case, there is a risk of accidents because trains in progress can not keep the gap with other preceding trains.

In order to prevent the risk of such an accident, it is determined based on the position sensor or the speed sensor implemented in the train that the signal of the fourth quadrant 5-state LED signal generator 440 is not detected at the current position, and the fourth quadrant 5-state LED It is possible to predict the signal generated at the signal generator 440 or to receive information about the signal that should be generated at the fourth quadrant 5-state LED signal generator 440.

For example, when the first train 460 is fixed and the second four-way LED indicator 440 fails, the second train 470 moves along the traveling direction of the first train 460 Can be assumed.

In this case, the second train 470 may preferentially acquire the attention signal and perform the progress in the third tri-state 5-state LED signal 430. The second train 470 is in progress and acquires a signal from the third tri-state 5-state LED signal 430. After the signal interval (for example, 100 m), the fourth quadrant 5-state LED signal 440 . If the fourth quadrant 5-state LED signal 440 fails, the second train 470 can not obtain a signal from the fourth quadrant 5-state LED signal 440. When the second train 470 fails to acquire a signal from the fourth quadrant 5-present LED signal 440 after 100 m after acquiring the signal from the third quadrant 5-present LED signal 430, the fourth quadrant 5 It can be determined that an abnormality has occurred in the LED signal generator 440.

In this case, second train 470 may obtain information about the signal of fourth quadrant 5-LED signal 440 in a variety of ways. First, the second train 470, if there is an LED signal controller controlling the LED indicator of the 5-state, displays information indicating that the signal was not acquired from the 4-second 5-state LED signal 440, And may request information about the location of the train 460. In this case, the LED signal manager may transmit information about the position of the first train 460 preceding the second train 470. Alternatively, the second train 470 may request the information of the location of the first train 460 to the first train 460 to obtain the location information of the first train 460.

Even if the train passes by another fault, there is a possibility that the trajectory circuit is not short-circuited so that the signal does not change due to the relay interlocking. Even in this case, the signal generated from the LED 5-state LED indicator can be controlled so that the train does not misread the signal.

FIG. 5 is a conceptual diagram illustrating a method for controlling a light emitting diode (LED) signal device of the present invention. FIG.

Referring to FIG. 5, the signal controller 500 determines whether the signal generated from the LED 5 is a correct signal based on the signals of the LED 5 and LED 5, It can be judged.

The signal controller 500 determines whether or not there is an error in the 5-state LED signal generator 550 based on the position information of the train and the information about the signal generated in the LED signal generator 550 can do.

The signaler controller 500 may predict a signal generated from the LED signal 550 of the light emitting diode 5 located on the line based on the position of the train moving on the current line. The signal of the LED display 550 of the quadrature 5-state LED signal predicted by the signal controller 500 is defined as the predicted quadrature 5-state LED signal. The signal controller 500 determines whether the presently generated signal of the pentode 5-present LED signal 550 differs from the predicted pentode 5-present LED signal and determines whether the current pentode 5-present LED signal 550 has not malfunctioned Can be determined.

For example, if the first train passes the track circuit, the signal of the LED 5 of the light-emitting diode 5 turns into a stop signal. When the signal is changed, the quadrature 5-state LED signal 550 may send information about the quadrature 5-state LED signal changed to the signal controller 500. The signal controller 500 compares the information of the signal transmitted by the LED signal 550 of the pentode 5 with the predictive LED 5 of the indicator and if the two signals are different from each other, It can be judged that there is a < / RTI > If there is no error in the altered signal of the LED 5, the LED 5 of the light emitting diode 550 may transmit a response signal indicating that the signal currently being changed is a correct signal.

Conversely, if there is an error in the signal modified by the quadrature five-state LED signal generator 550, the signal controller 500 will undergo further verification as to whether the predictive quadrature 5-present LED signal 520 is correct, It may send a correction request signal 530, such as an LED requesting modification of the signal of the quadrature 5-state LED signaler, to the quadrature 5-state LED signaler 550 based on the predicted quadrature 5-present LED signal 520. The quadrature 5-state LED signal 550 receiving the correction request signal, such as an LED, may change the signal of the quadrature 5-state LED signal 550 based on the received signal.

In addition, information indicating that an error may exist in the signal system of the current five-mode LED indicator 550 may be transmitted to the train running on the track so that the train can be safely operated. For example, a train that received information indicating that the signaling scheme of the current five-state LED indicator 550 may be faulty, may be coupled to a preceding train by a further preceding train sensing device (e.g., a radar) Information about the distance can be obtained and additional information about the position of the preceding train can be obtained.

By using this method, it is possible to prevent accidents between trains due to signal errors.

FIG. 6 is a conceptual diagram illustrating a method of analyzing a signal generated in a light-emitting diode (LED) signal device of a five-level display in a train according to an exemplary embodiment of the present invention.

FIG. 6 shows a method for transmitting information on a signal generated from a light emitting diode (LED) signal of a five-state LED when the operator of the train does not see a signal generated from the LED light signal of the LED light signal of the 5-state. This method may only be carried out if the operator does not see the signal, but if the operator is used to re-determine whether the signal is clear, a continuous five-way LED signaler And transmits the information to the train operator through the display.

Referring to FIG. 6, a method of analyzing a signal generated in an LED signal of an even-five-state through an image capturing unit and an image information analyzing unit 600 provided in a train will be described.

For example, the image information analyzing unit 600 can determine whether a signal generated from the LED 5 is a signal generated based on the image information captured by the image capturing apparatus mounted on the train.

For example, the spots information analysis unit 600 acquires image information of a portion in which the LED 5 is lighted, and the first and second LEDs included in the LED 5 are connected to each other, Information on whether or not the image is radiated can be performed through pixel analysis of the acquired image.

The information about the current pixel can be displayed on the monitor that the operator can view based on the screen information analyzed by the image information analyzing unit 600. [

FIG. 7 is a conceptual diagram illustrating a method of operating a signal system differently according to a travel route of a train according to an embodiment of the present invention.

In Fig. 7, a method of operating a signal system considering the actual train speed is disclosed.

In fact, it is possible to operate the signal system by taking the actual speed of the train into consideration when operating the train. For example, an interval of 100 meters with a five-LED light signal on the trains running at full speed may be a fast traverse. However, if a train stops at the station and then moves to the next station, the 100m section may not be a section where the train is moving fast. Therefore, the signal indicating the deceleration of the train can be set differently considering the moving speed of each section.

It can be assumed that the first train 760 moves after the stationary movement in the reverse direction to change the signal of the first five-state LED signal generator 710. In this case, the default value by the relay interlocking is the progress signal of the 5 th second 5-state LED signal transmitter 750 located before 400 m, the 4 th second 5-state LED signal transmitter 740 located 300 m before the deceleration signal, A 3-way 5-state LED signal 730 may indicate a caution signal, and a 2-second 5-state LED signal 720 located 100 m prior may indicate a boundary signal.

However, since the first train 760 changes the signal of the first five-state LED indicator 750 in the above manner, the travel time may be long after the train travels after stopping. In this case, in order to reduce the risk of an accident, the fifth 5-minute LED display signal 750 is also changed to a deceleration signal instead of a progress signal, so that another train 770 traveling along the first train 760 is driven by the first train 760 It can be implemented to reduce the speed in advance in consideration of the movement.

In order to perform this method, the speed of the train 760 that changed the signal of the first first five-mode LED signal 710 is calculated and is lower than a predetermined threshold value, the speed of the first 5-way LED signal 710 Signal may be set to have the value of the deceleration signal up to the fifth, fifth, fifth, and present LED signal 750 located before the signal. For example, if the signal of the first five-state LED indicator 710 is changed to a stop signal due to the train 750 moving at a speed of 10 km / h or less by setting a speed of 10 km / h as a threshold value, It is possible to control so that the signal 5 750 of the fifth 5-state LED signal is changed to the deceleration signal instead of the progress signal. Conversely, if the signal of the first twisted five LED indicator 710 is changed to a stop signal due to a train moving at a speed of more than 10 km / h, the signal of the fifth twisted five LED indicator 750 at the default value It can be set to keep the progress signal.

As an example of such a signal control method, it is possible to use a signal change system different from the default signal change based on relay information based on the current train position information and the train speed information.

For this additional control, a signal controller can be implemented. The signal controller can acquire information on the speed of the train, and when the signal operation other than the default value is to be performed based on the signal, the signal controller can control the signal transmitter by transmitting a separate control signal. In addition, the LEDs of the light emitting diode 5 shown in FIGS. 1 to 7 may be implemented as a single system to control the operation of the LEDs of the light emitting diode 5, which is included in the system.

8 is a conceptual diagram illustrating a signal controller according to an embodiment of the present invention.

8, the signal control unit includes a signal information receiving unit 800, a train position information receiving unit 810, a train speed information receiving unit 820, an error determination unit 830, a signal control unit 840, a communication unit 850, And a processor 860.

The signaling device information receiving unit 800 may be implemented to collect information about a signal generated in the LED-signaling device of the present invention. The information on the signal of the light emitting diode 5 signal of the present invention received by the signal transmitter information receiver 800 may be transmitted to the error detector 830.
