The present invention relates to a collision avoidance system with other trains when the train is derailed, and more particularly, when the train derails while driving and occupies or approaches the opposite driving track or the side track, the train detects the derailment of the train and informs it to the situation room. To prevent other trains from entering the relevant train derailment area in the situation room so as to prevent the occurrence of secondary accidents caused by collisions and collisions of other trains on the trains where the first derailment accident occurred, and to promptly rescue and recover. Invented.

In general, when a train derails while driving, occupying or approaching an opposite track or a side track, collisions and collisions between trains and trains occur, causing a great casualty.

Meanwhile, the signal control system [ATS (Automatic Train Stop), ATC (Automatic Train Control), ATP (Automatic Train Protection), etc.] based on the current track circuit performs the interval control and train path control between the preceding trains and the following trains. In the process of securing high safety.

At this time, the ATS (Automatic Train Stop) refers to the automatic speed stop or point controlled train automatic stop device to automatically stop or decelerate the train when the train exceeds the signal instruction speed or ignores the signal system, ATC (Automatic Train Control) refers to a train automatic control device that transmits the driving conditions of a train on track so that it can be operated automatically without a ground signal, and ATP (Automatic Train Protection) is a concept of the ATC device, It is a train automatic protection device that controls the speed of the rear train according to its position.

On the other hand, currently operating ATS, ATC, ATP, etc. are mostly using the track circuit, and recently developed CBTC (Communication Based Train Control) to secure the safety of train operation using wireless communication.

It is proved that such a device has secured sufficient safety to date, but many accidents such as personal injury and damage to facilities occur due to the occasional failure.

In order to solve this problem, some trains are provided with an auxiliary device such as a train protection device.

However, even when such a train protection device is used, an accident that a train derails and collides with an opposite train has a fundamental problem that cannot be prevented.

1A illustrates a state in which the head vehicle 2 of the train derails the track and stops in a state close to the opposite track 1.

In the case of such a derailment, the situation room can confirm that the train has stopped, but it cannot confirm that the train has derailed and approached the other track.

FIG. 1B illustrates a situation in which a lead vehicle 2 of a train derails the track 1 so that a part of the lead vehicle extends on the opposite track 1.

In the event of such a derailment, the situation room can confirm that the train has stopped, but cannot confirm that the train has derailed and approached the other track.

FIG. 1C illustrates a situation in which the head vehicle 2 of the train derails the track 1 and completely occupies the opposite track 1.

In this case, the track circuit of the opposite track can confirm this, but it cannot always be detected that the track circuit has derailed according to the derailment state of the leading vehicle.

As the train derailed as described above, the situation of approaching or occupying the opposite track cannot be confirmed in the operation room, so the vehicle 2 of the other train driving the other track as shown in FIG. Running on the vehicle 2 cannot be prevented.

As a result, the vehicle 2 of the train in which the first accident has already occurred and the vehicle 2 of another train normally running on the other track 1 collide with each other, resulting in a second accident such as death or damage to the facility.

Therefore, in the conventional system, in the case of a minor train derailment, the driver of the derailed train may immediately notify the situation room to block the train entering from the other side, but the train derailment of the train derailed is very serious. If the situation room can not be notified immediately there is a problem that can not prevent the train crash.

The present invention has been made in order to solve the above-mentioned conventional problems, and when the train derails from the track due to some reason while driving, occupies or approaches the opposite driving track or the side track and detects the derailment of the train to notify the situation room or the like. By making it possible to recognize the situation immediately in the situation room and block other trains from entering the train derailment area, it is possible to prevent the occurrence of the second accident due to the collision and collision of another train on the train where the first derailment accident occurred. In addition, the aim of the present invention is to provide a collision avoidance system with other trains during train derailment, which can be quickly rescued and restored.

In order to achieve the above object, the present invention provides a collision avoidance system, comprising: a derailment detection signal line installed between a vehicle and a vehicle and detecting whether a train derails; A signal processor which receives the state signals of the derailment detection signal lines and determines whether the train derails; It is basically installed in any one or both of the front vehicle or the rear vehicle, and when the derailment detection signal of the train is input from the signal processing unit is configured as a wireless signal transmission unit for wireless transmission to the situation room.

In this case, the derailment detection signal line is an emergency braking communication line used in a train for a passenger train, a TCMS (Train Control & Monitoring System) or in-vehicle signal device communication line installed in the head vehicle and the rear vehicle to control the electronics of the vehicle. And a communication line for broadcasting and the like, and if a TCMS and a broadcasting communication line are not installed, such as a freight train, a separate signal line is installed.

On the other hand, the signal processing unit and the interface unit for transmitting various signals (emergency braking signal, in-train communication signal and passenger guidance communication signal, etc.) input in real time through the derailment detection signal lines to the delay unit without processing; Delay units for delaying each signal input through the interface units by a recovery time after a failure required by the device; If any one of the signals to be input through the delay unit has not been transmitted for more than a predetermined time is considered to be an abnormal state (that is, derailment) characterized in that configured as a derailment state determination unit for generating an abnormal signal to the wireless signal transmission unit do.

In addition, the ground is provided with a repeater for relaying a variety of communication signals including the derailment detection signal transmitted from the wireless signal transmission unit as necessary.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Figure 6 shows the side and plan view of the train shown, Figure 6 shows an exemplary view showing the state of the derailment detection signal line in the curved portion, Figure 7 shows a detailed block diagram of the signal processing unit of the present invention system.

Accordingly, the collision avoidance system of the present invention includes a derailment detection signal line 3 which is detachably installed between the vehicles 2 and detects whether a train derails, including transmission of various signals;

A signal processor 4 which receives the state signals of the derailment detection signal lines 3 and determines whether the train derails;

Optionally installed in any one or both vehicles of the head vehicle or the rear vehicle, when the derailment detection signal of the train is input from the signal processing unit 4, the radio signal transmitting unit 5 which transmits it to the situation room of a remote place. It features.

At this time, the derailment detection signal line (3) is installed so as to sag down a certain height (ℓ) to the lower part in the normal state so that the disconnection is not made when the train runs the curved track (1) at a predetermined speed. It is done.

On the other hand, the derailment detection signal line (3) is installed in the emergency braking communication line used in the train in the case of passenger trains, TCMS or in-vehicle signal device communication line and broadcasting communication line installed in the leading vehicle and the rear vehicle to control the electrical equipment of the vehicle And if the TCMS and broadcasting communication line is not installed, such as freight train, it is characterized in that a separate signal line is installed.

In addition, the signal processing unit 4 is detected deviation signal line 3, the delay section (42 without processing the various signals (emergency brake signal, a train signal within the communications and passengers do not communicate information signal) that is input in real time over a ₁ -42n ) interface unit (41 ₁ -41n) for transmitting to and;

Said interface unit (41 ₁ -41n) of the delay section (42 ₁ -42n) each of which was delayed by a time to consider the recovery time after a failure occurs that requires the various signals in the apparatus is inputted through the;

Derailed state is determined for generating the delay unit to generate at least considered to be an abnormal state, if not been transmitted (42 ₁ -42n) than those at any one signal of the signals to be input through a predetermined time signal to the wireless signal transmission unit 5 It is characterized by comprising the portion 43.

In addition, the signal processing unit 4 is characterized in that additionally provided with a power supply unit 44 having a charging function in order to continue to transmit the derailment detection signal through the wireless signal transmitting unit 5 even if a power failure occurs. .

On the other hand, it is characterized in that the ground further provides a repeater 6 for relaying various communication signals including the derailment detection signal transmitted from the radio signal transmitter 5 to the situation room as needed.

Referring to the effects of the collision avoidance system with other trains when the train derailment of the present invention configured as described above are as follows.

First, the system of the present invention is largely composed of a derailment detecting signal line 3, a signal processor 4, and a radio signal transmitter 5.

At this time, the derailment detection signal line (3) is a variety of signal lines or communication lines passing through the vehicle (2) of the train TCMS for controlling the vehicle electrical equipment is installed in the emergency braking human traffic line used in the train, the leading vehicle and the rear vehicle ( Train control and monitoring system) or in-vehicle signal communication line and broadcasting line.

Of course, when a communication line for TCMS and broadcasting is not installed, such as a freight train, a separate signal line is used.

The derailment detection signal line 3 is disposed at both sides between the vehicle 2 and the vehicle 2 of the train as shown in FIG. 5 (a) and (b). The signal line using the high voltage and the signal line using the low voltage Separate from each other.

In addition, the derailment detection signal line (3) as shown in Figure 5 (a) is installed with the ear canal to be sag by a certain height (ℓ) to the lower part in the normal state so that the disconnection is not made when the train is running curved at a predetermined speed. do.

If the derailment detection signal line 3 does not have an ear canal as much as a predetermined height ℓ, the derailment detection signal line 3 is broken when the train runs a curved portion as shown in FIG. 6.

At this time, if the ear canal is excessively applied, the derailment detection signal line 3 is damaged by contact with the traveling path surface, and wear occurs, and eventually, the part of the derailment detection signal line 3 is cut off.

Therefore, the size of the ear canal should be determined by considering the radius of the curve on the track on which the train runs and the inclination of the train generated when driving the curve.

On the other hand, running trains derail due to various factors such as wheel breakage, inter-vehicle connector breakdown, line breakage, exceeding the speed limit in curved sections and gradient sections, and collisions between preceding and subsequent trains.

In the case of a minor derailment accident, only a few of the vehicles constituting the train depart from the railroad tracks without causing any serious problems.In this case, emergency braking is applied to the train by the signal control system installed in the train. Is done.

However, a serious derailment accident causes a large number of vehicles constituting the train to be thrown out of the train and severely damaged or overturned, resulting in many casualties and serious damage to facilities.

When such a serious derailment accident occurs, the derailment detection signal line 3 which is the connection line connected between the vehicles is cut off.

When such an accident of cutting the derailment detection signal line 3 occurs, the in-train communication line used by devices such as human traffic lines used for emergency braking, TCMS or onboard signaling devices, and communication lines used for passenger guidance are blocked.

Accordingly, as shown in FIG. 7, the signal processor 4 determines that the derailment detection signal line 3 is disconnected when any one of these input signals has no input (i.e., is blocked), and transmits the train derailment signal to the radio signal. Output to negative 5.

That is, the signal processor 4 is installed in the radio signal transmitter 5 one by one to monitor the state of the signals input from the derailment detection signal line 3 when it is determined that the train is derailed, the radio signal transmitter Send to (5).

In this case, the signal processing unit 4 may not be installed in the tail vehicle depending on the type of train.

That is, in general, when the train control vehicle is located in the head and tail cars, such as subways and high-speed rail, it can be installed on both sides, but in the case of cargo trains or general passenger trains, the signal processing unit 4 is provided only in the head vehicle.

On the other hand, the signal processing unit 4 is configured as the interface unit (41 ₁ -41n) and a delay unit (42 ₁ -42n) and deviation state determining section 43 to the default, this is a power failure, if necessary In order to be able to continuously generate the derailment detection signal through the wireless signal transmitter 5, a power supply unit 44 having a charging function is additionally provided.

Therefore, even though the power supply voltage is not supplied to the signal processing unit 4 due to an accident such as a derailment, the power supply unit 44 provided therein is continuously supplied with the power supply voltage, thereby continuously detecting the derailment detection signal and transmitting the wireless signal. (5) It is possible to continuously generate information on the derailment of the train to the situation room, so that the situation room immediately recognizes this and blocks other trains from entering the train derailment area so that other trains on the first derailment accident occurred. Secondary accidents caused by collisions and collisions can be prevented, as well as rapid rescue and recovery measures can be taken.

In this case, the interface unit (41 ₁ -41n) are without processing the various signals in the emergency brake signal, a communication signal train and the passengers do not communicate information signal input in real time with the deviation detection signal (3) only a deviation detection signal (3) determine if it is working normally to be forwarded to the delay unit (42 ₁ -42n), the delay unit (42 ₁ -42n) are the various signals input via the interface, this portion (41 ₁ -41n) After the failure required by the device is delayed by each predetermined time considering the recovery time is delivered to the derailment determination unit 43.

By the way, the emergency braking device, TCMS device, onboard signal device, broadcasting device, etc. installed in the train may be restored after a short time due to an error in the device. Can cause many problems.

Accordingly, the delay unit (42 ₁ -42n) of the invention after a failure is required by each device in consideration of the recovery time kept by setting the delay time.

In addition, the deviation state determining section 43, the delay unit (42 ₁ -42n) of any one signal of the signals to be input through any certain time is transmitted over the radio signal sent over the signal generated is regarded as an abnormal state, if not The derailment determination unit 43 determines the train derailment of the derailment determination unit 43 to logically determine the arrangement of the derailment detection signal line 3.

On the other hand, the radio signal transmitting unit 5 is selectively installed in any one or both vehicles of the head vehicle or the rear vehicle, and when the derailment detection signal of the train is input from the signal processing unit 4, it is wirelessly transmitted to the situation room of a remote place. Done.

In this case, when the train and the situation room are relatively far from each other, various communication signals including the derailment detection signal transmitted from the wireless signal transmitter 5 may be difficult to accurately transmit to the situation room of a remote location without distortion.

Therefore, according to the present invention, if necessary, a separate communication signal including a derailment detection signal transmitted from the radio signal transmitter 5 is provided by installing a repeater 6 on the ground separately from the radio signal transmitter 5 of the vehicle. Amplified to the situation room without distortion to be relayed.

Therefore, various communication signals including the derailment detection signal transmitted wirelessly from the wireless signal transmitting unit 5 installed on the vehicle are transmitted to the situation room in real time through the repeater on the ground or directly to the situation room and displayed on the facility of the situation room. The operating personnel can recognize this immediately and take immediate action.

In addition, only the current train that does not use a lot of radio communication device is installed and use a dedicated radio signal transmitter (5), in the case of the currently active development of wireless communication-based train control system wireless communication to be used in the train control system It is considered appropriate to utilize the device.

Although the above-described embodiments have been described with respect to the most preferred examples of the present invention, it is not limited to the above embodiments, and it will be apparent to those skilled in the art that various modifications are possible without departing from the technical spirit of the present invention.

As described above, according to the present invention, when the derailment detecting signal line, the signal processing unit and the wireless signal transmitting unit are installed on the vehicle, the train derails the track for some reason while driving and occupies or approaches the opposite driving line or the side track. Detects the derailment of the train and sends it to the situation room so that it is immediately recognized by the situation room and blocks other trains from entering the train derailment area. Can be prevented in advance, as well as the structure and recovery can be quickly taken.

Also, if necessary, a repeater is installed on the ground so that even if the train and the situation room are relatively far apart, various communication signals, including the derailment detection signal transmitted from the radio signal transmitter, can be accurately transmitted to the remote situation room without distortion. In remote situation rooms, trains can immediately recognize the derailment of trains, block other trains from entering the train derailment area, and take the necessary steps for rescue and recovery.

In addition, even if the power supply voltage is not supplied due to an outage caused by an accident such as a derailment, the signal processing unit continuously supplies the power supply voltage from the power supply unit provided therein to continuously detect the derailment detection signal even in the event of a power failure due to an accident. By detecting and continuously generating information about the derailment of the train to the situation room through the wireless signal transmitter, it immediately recognizes the situation in the situation room and blocks other trains from entering the relevant train derailment area to prevent the train from derailing. It is a very useful invention that can prevent the occurrence of secondary accidents due to collisions and collisions of other trains, as well as quick rescue and recovery measures.
