Referring to FIG. 1, a secondary accident prevention system 10 in a tunnel according to an embodiment may include a transfer unit 100, a buffer unit 200, a monitoring unit 300, and a control unit 400.

The secondary accident prevention system 10 in the tunnel according to one embodiment can be installed in the tunnel by utilizing the configuration existing in the existing tunnel.

Generally, there may be a guardrail installed on a ceiling of a tunnel for electric lamps, electric wires, etc. The guard rails may be present in the respective lane positions, and a plurality of guard rails corresponding to the number of lanes may be present in the tunnel.

There is also a management office for managing the tunnels, and the wiring and communication lines installed in the guard rails can be connected to the control server of the management office.

In the meantime, a position detection sensor such as a CCTV, a rider sensor, or a radar sensor can be installed in the tunnel to confirm the position or the accident point of the vehicle. Such a position detection sensor can be managed through the existing ITS (Intelligent Transport System) The detection data can be transmitted to the control server of the office in real time.

First, the secondary accident prevention system 10 in the tunnel according to an embodiment is configured such that, when an accident occurs due to a collision between the first vehicle A1 and the second vehicle A2 in the tunnel, The second vehicle A2 is referred to as a front vehicle or an accident vehicle and the third vehicle A3 is hereinafter referred to as an accident vehicle. Is referred to as a rear vehicle.

The conveyance unit 100 can be conveyed along a conveyance rail R provided in a ceiling in a tunnel and includes a first conveyance member 110 conveyed from an entrance portion of a tunnel to a first delivery position, And a second transfer member 120 which is transferred onto the second delivery position.

2, a plurality of conveying rails R may be arranged in a ceiling in a tunnel, and a first conveying rail R1 is disposed on a first lane and a second conveying rail R2 is disposed on a second lane. . At this time, the first conveying member 110 and the first cushioning member 210 can be conveyed from the entrance portion toward the accident vehicle A2 through the first conveyance rail R1 and the second conveyance rail R2, The second conveying member 120 and the second cushioning member 220 can be conveyed from the advancing portion toward the accident vehicle A2 from the first conveying rail R1 and the second conveying rail R2.

However, the number of the plurality of conveying rails R is not limited to this, and may be variously provided so as to correspond to the number of lanes in the tunnel.

Specifically, the first conveying member 110 can transfer the first cushioning member 210 connected to the first conveying member 110 from the entrance of the tunnel to the first dropping position, and at the same time, The transfer member 120 can transfer the second buffer member 220 connected to the second transfer member 120 from the advancing portion of the tunnel to the second transfer position.

At this time, the first drop position may be a position separated from the accident vehicle A2 in the tunnel by a rear safety distance, and the second drop position may be a position adjacent to the rear of the accident vehicle A2 in the tunnel, for example, It can be just behind the accident vehicle.

The safety distance may be calculated based on the average vehicle speed or the maximum limit speed in the tunnel. For example, on a highway with a maximum speed limit of 100 km / h, the safety distance may be 100 m. In this case, the first conveying member 110 is conveyed from the entering portion of the tunnel to the point 100 m behind the accident vehicle A2, and the first cushioning member 210 connected to the first conveying member 110 is also moved to the entrance To the rear 100m of the accident vehicle A2.

Thus, the movement of the first conveying member 110 and the second conveying member 120 can be determined by the position of the accident vehicle A2.

Specifically, when the monitoring unit 300 including the CCTV installed in the tunnel, the radar sensor, the lidar sensor, and the infrared sensor detects an accident, the ID of each sensor or the tracking coordinate And the detected location information is transmitted to the control unit 400 disposed at the management office through the first communication line C1. The control unit 400 notifies the first conveying member 110 of the position coordinates through the second communication line C2 and notifies the second conveying member 120 through the third communication line C3.

At this time, the control unit 400 may calculate the coordinates of the rear safe distance and the first delivery position of the accident vehicle A2 and transmit the control signal, for example, coordinate information of the first delivery position to the first delivery member 110 At the same time, the control unit 400 calculates coordinates of the second delivery position adjacent to the rear of the accident vehicle A2 and outputs control signals to the second delivery member 120, for example, coordinate information of the second delivery position Can be transmitted.

The buffer portion 200 can be conveyed along the conveying rail R by the conveying portion 100 as described above.

The buffer part 200 may be dropped to the rear of the accident vehicle A2 in the tunnel to prevent or mitigate the collision of the rear vehicle A3 with the accident vehicle A2.

The buffer part 200 is mounted on the first transfer member 110 and mounted on the first buffer member 210 and the second transfer member 120 to be transferred by the first transfer member 110, And a second buffer member 220 that is transported by the second buffer member 120.

At this time, the first cushioning member 210 is dropped by the position of the first conveying member 110 and the second conveying member 120 to the first delivering position spaced apart from the accident vehicle A2 by the rear safety distance, The second cushioning member 220 can be dropped to the second delivery position adjacent to the rear of the accident vehicle A2.

Particularly, since the first cushioning member 210 is dropped from the accident vehicle A2 to the first dropping position spaced apart from the accidental vehicle A2 by a rear safety distance, it is possible to replace the existing tripod, have.

The second cushioning member 220 can be dropped to the second delivery position when the rear vehicle A3 has passed the first cushioning member 210 and the first cushioning member 210 of the rear vehicle A3 It is possible to determine whether the second buffer member 220 is released and developed.

For example, when the rear vehicle A3 passes through the first cushioning member 210, the second cushioning member 220 is released and developed, and the rear vehicle A3 passes through the first cushioning member 210 The second buffer member 220 may not be released and developed.

In particular, with reference to Figs. 3 and 4, the above-described transfer unit 100 and the buffer unit 200 may be configured as follows.

The transfer unit 100, specifically, the first transfer member 110 or the second transfer member 120 may include a housing 102, a frame 104, a wheel member 106, and a drive motor 108 .

The housing 102 may be provided to house the frame 104, the wheel member 106 and the drive motor 108 so that the frame 104, the wheel member 106 and the drive motor 108, Can be prevented from being exposed to the outside. This may be preferable in that collision with an electric wiring or the like disposed on the ceiling in the tunnel can be avoided.

The frame 104 can be transported along the upper end of the transport rail R and the buffer part 200 can be connected to the lower end of the frame 104. [

The wheel member 106 can be mounted on the side of the frame 104 and moved along the upper end of the feed rail R in contact therewith. For example, the wheel member 106 may be provided in four, and the frame 104 may be provided so that the four wheel members 106 are connected to each other.

4, the wheel member 106 may further include an additional wheel member 106a so that it can be moved along the lower end as well as the upper end of the transferring rail R. [

The frame member 104 can be transported more reliably along the feed rail R by moving in contact with the upper and lower ends of the feed rail R by the wheel member 106 and the additional wheel member 160a.

The drive motor 108 may be mounted on one side of the frame 104, for example, in front of or behind the frame 104. At this time, a driving force is obtained through the output of the driving motor 108. The power of the driving motor 108 is connected to a power supply line installed in the tunnel or charged at the entrance of a tunnel, for example, .

On the other hand, the buffer part 200 may include a case 202 and a gas supplier 204.

The case 202 may be connected to the lower end of the frame 104 of the transfer unit 100 and may be transferred by the transfer unit 100. When the first buffer member 210 or the second buffer member 220 is contracted Lt; / RTI >

Further, the case 202 may be connected to the frame 104 so as to be adjustable in height. For example, the frame 104 may be provided with a length adjusting member 1042, and the height of the case 202 with respect to the frame 104 can be adjusted by the length adjusting member 1042. Thus, when the illuminating device under the feeding rail R is provided, collision between the case 202 and the illuminating device can be avoided.

The gas supplier 204 may be connected to one side of the case 202 to develop the first cushioning member 210 or the second cushioning member 220 dropped from the case 202.

For example, the gas supplier 204 may be provided with a compressor, and a gas injection hose 2042 connected between the gas supplier 204 and the first cushioning member 210 or the second cushioning member 220, For example, nitrogen gas or compressed air, may be injected from the gas supplier 204 into the first cushioning member 210 or the second cushioning member 220 by means of the gasket 204.

At this time, it is natural that the gas supplier 204 can be remotely controlled by the control unit 400.

The first cushioning member 210 may include a plurality of airbags 212 and the plurality of airbags 212 may be connected by a connecting member 2122. [

For example, the plurality of airbags 212 may be provided with three airbags.

In the case of a tunnel height of 4.5 m, the three airbags 212 would total 1 m and the lowest airbag could be spaced 30 cm above the road.

However, the number or height of the plurality of airbags 212 is not limited to this, and any of them can be contacted with the rear vehicle.

Since the plurality of airbags 212 are connected by the connecting member 2122, the movement of the plurality of airbags 212 is fluid, and the impact on the conveyor 100 itself can be alleviated when the airbag 212 collides with the vehicle.

5, when the rear vehicle A3 passes through the first cushioning member 210 released from the first conveying member 110 and deployed, the first cushioning member 210 causes the rear vehicle A3 ) Can be mitigated. The second buffer member 220 is dropped between the rear vehicle A3 and the accident vehicle A2 from the second conveyance member 120 so as to buffer the secondary vehicle A3 and the accident vehicle A2 Effect can be obtained.

The plurality of airbags 212 may be arranged to be deployed instantaneously by injecting nitrogen gas through an electrical signal, such as an airbag for a vehicle.

For example, when a plurality of airbags 212 can not be deployed due to an external factor, a plurality of airbags 212 may be deployed by receiving gas from the gas supplier 204.

At this time, characters or shapes such as "forward accident "," STOP ", and the like are displayed on the plurality of airbags 212 so that the driver of the rear vehicle can be notified that an accident vehicle exists ahead.

Referring again to FIG. 3, the first cushioning member 210 may be equipped with a sensor 2124 for detecting the passage of the vehicle. The sensor 2124 may include an inertial sensor or a pressure sensor including a gyro sensor and an acceleration sensor.

Specifically, when the rear vehicle passes without stopping in front of the first cushioning member 210, the second cushioning member 220 can be released and deployed to prevent a secondary accident. At this time, passage of the vehicle is detected by the sensor 2124 mounted on the first cushioning member 210 and the signal sensed by the sensor 2124 is transmitted to the control unit 400. In the control unit 400, And may transmit a control signal for the release and deployment of the member 220.

Further, when the rear vehicle collides with the second cushioning member 220, it is determined that a secondary accident has occurred. Therefore, when a collision is detected by the sensor mounted on the second cushioning member 220, And the control unit 400 can report the signal to the outside such as 119 or a related organization to proceed with the subsequent incident processing.

Although the first buffer member 210 has been described with reference to FIG. 3, it is needless to say that the second buffer member 220 may also be constructed in the same manner.

Referring again to FIG. 1, the monitoring unit 300 may include a CCTV installed in the tunnel, a rider sensor, a radar sensor, an infrared sensor, and the like.

The monitoring unit 300 can detect the location or the accident point of the accident vehicle in the tunnel and can transmit the location information of the accident to the control unit 400 through the first communication line C1 when an accident occurs in the tunnel.

In addition, the control unit 400 may be provided as a control server. The control unit 400 may receive the sensed data acquired by the monitoring unit 300, for example, position information of the accident, and may control the operation of the transfer unit 100.

For example, when an accident in the tunnel is sensed, the control unit 400 transmits a control signal to the first conveying member 110 through the second communication line C2 and transmits a control signal to the second conveying member 110 through the third communication line C3. A control signal may be transmitted to the control unit 120.

At this time, the controller 400 can calculate the position information of the first delivery position and the second delivery position, and controls the first delivery member 110 and the second delivery member 120 based on the calculated position information Signal can be transmitted.

Here, the case where the control signal is transmitted by wire is described as an example, but it is natural that the control signal can be wirelessly transmitted.

Alternatively, the control unit 400 receives data sensed by a sensor mounted on the first cushioning member 210 or the second cushioning member 220, for example, whether the vehicle has passed or not, Can be controlled.

For example, when the passage of the rear vehicle A3 is detected from a sensor mounted on the first cushioning member 210, the control unit 400 may transmit a release and deployment signal to the second cushioning member 220 . On the other hand, when the passage of the rear vehicle A3 is not detected from the sensor mounted on the first cushioning member 210, the control unit 400 may not transmit the release and deployment signals to the second cushioning member 220 have.

In addition, when a rear-end vehicle A3 collides with the accident vehicle A2, a sensor mounted on the second cushioning member 220 senses a secondary accident, and the control unit 400 detects the first conveying member 110, A control signal may be transmitted to the first conveying member 110 so as to be positioned at a position spaced from the rear vehicle A3 by the rear safety distance, that is, on the first delivery position.

At this time, a new first delivery position is calculated in the control unit 400, and the first cushioning member 210 is placed at the first delivery position by the transfer of the first delivery member 110, It can prevent accidents.

In order to prevent a secondary accident in the tunnel, the controller 400 can monitor the situation in the tunnel in real time, transmit the control signal in real time, and control the inside of the tunnel as a whole.

The secondary accident prevention system in the tunnel according to one embodiment has been described, and the prevention of the secondary accident in the tunnel according to one embodiment will be described below.

6 and 7 are flowcharts illustrating a procedure for preventing a secondary accident in a tunnel according to an embodiment.

6 and 7, a secondary accident in the tunnel can be prevented as follows.

First, a secondary accident prevention system in the tunnel according to one embodiment described above, for example, a shock absorber and a transportation unit, is installed on a rail provided in a ceiling in a tunnel (S10).

Then, the inside of the tunnel is monitored by the monitoring unit provided in the tunnel (S11).

For example, the monitoring unit is provided with a CCTV, a rider sensor, a radar sensor, or an infrared sensor, and can monitor an accident in a vehicle, a tunnel in a tunnel, or the like.

When the occurrence of an accident in the tunnel is detected by the monitoring unit (S12), and the occurrence of an accident in the tunnel is detected by the monitoring unit, the position information of the accident point detected by the monitoring unit is transmitted to the control unit (S13).

At this time, it is a matter of course that the monitoring unit can transmit not only the location information of the accident point but also the information about the inside situation of the tunnel to the control unit in real time.

Then, the rear safety distance of the accident vehicle is calculated by the control unit (S14).

At this time, the rear safety distance of the accident vehicle can be calculated by calculating the rear vehicle average speed, and the average speed of the rear vehicle can be detected by the monitoring unit.

Subsequently, the control signal transmitted from the control unit causes the first buffer member to be positioned on the first delivery position by the first delivery member and the second buffer member to be positioned on the second delivery position by the second delivery member (S15 ).

At this time, the first drop position may be a position separated from the accident vehicle by a rear safety distance, and the second drop position may be a position adjacent to the rear of the accident vehicle or directly behind the accident vehicle.

As such, the first buffer member and the second buffer member can be simultaneously disposed at the respective positions by the first transfer member and the second transfer member.

Then, the first buffer member is released and developed (S16).

At this time, the dispensing and deployment of the first cushioning member can also be controlled by the control unit, and when it is detected that the first conveying member is positioned on the first dispensing position, the first cushioning member can be automatically set to be dispensed and deployed have.

A sensor mounted on the first cushioning member is actuated (S17), and a sensor mounted on the first cushioning member detects whether the rearward vehicle has passed (S18).

The sensor may be provided with an inertial sensor or a pressure sensor, and data measured at the sensor may be changed by collision of the first buffer member and the rear vehicle.

For example, when the rear vehicle passes through the first cushioning member, the passage of the rear vehicle can be sensed because the value of the inertial sensor or the pressure sensor changes. On the other hand, when the rear vehicle is stopped in front of the first cushioning member, The value measured by the inertial sensor or the pressure sensor can be 0 because the vehicle does not collide with the first cushioning member.

When the passage of the rear vehicle is detected by the sensor mounted on the first cushioning member, the collision position information of the first cushioning member sensed by the monitoring unit and the rear vehicle is transmitted to the control unit (S19).

Subsequently, the second buffer member is released and developed by the signal transmitted from the control unit (S20).

In other words, whether or not the second cushioning member is released and deployed can be determined by whether or not the rearward vehicle sensed by the sensor mounted on the first cushioning member passes, and in some cases, the second cushioning member may not be deployed and deployed have.

Then, a sensor mounted on the second cushioning member is operated (S21), and a sensor mounted on the second cushioning member detects whether the rear vehicle collides (S22).

When the collision of the rear vehicle is detected by the sensor mounted on the second cushioning member, the collision position information of the second cushioning member and the rearward vehicle sensed by the sensing unit is transmitted to the control unit (S23).

This indicates the occurrence of a secondary accident in the tunnel, and a secondary accident occurrence signal in the tunnel is immediately transmitted to the outside from the control unit (S24).

At this time, the outside can be related institutions such as 119 and 112.

Then, the rear safety distance of the secondary accident vehicle is calculated in the control unit (S25), and the first buffer member is located at the first delivery position by the control signal transmitted from the control unit (S26).

This is to prevent a third accident or a fourth accident in the tunnel, and the first drop position may be a position separated from the second accident vehicle or the existing rear vehicle by a rear safety distance. In this manner, the first delivery position is updated not according to the fixed position but the inner situation of the tunnel, and the first delivery position information can be transmitted to the first delivery member.

It goes without saying that the second buffer member can be transferred by the second transfer member to the second delivery position or the home position by the control signal transmitted from the control unit.

For example, when the first transferring member and the second transferring member are returned to their original positions, the gas in the first buffering member and the second buffering member is removed so that the first buffering member and the second buffering member are contracted, And can be housed in the case.

The system and method for preventing a secondary accident in a tunnel according to an embodiment of the present invention can prevent an accident in a tunnel in a rear vehicle of an accident vehicle by a buffering part and a transfer part when an accident occurs in a tunnel, And it is possible to minimize the damage even if a secondary accident occurs in the tunnel and further prevent the occurrence of the third or fourth accident.
