[0023] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0024] Embodiment 1

[0025] like Figure 1 , Figure 3 , Figure 4 As shown, a tunnel intelligent emergency traffic control system includes a plurality of first barrier machines 1 and a controller 5 arranged on the outside of a road guardrail, wherein the first barrier machine 1 is arranged at a first set distance in front of a tunnel entrance 21 of a tunnel 2, and a second set distance is provided between each first barrier machine 1; the length of the barrier of the first barrier machine 1 gradually decreases with increasing distance from the tunnel entrance 21; the height of the barrier of the first barrier machine 1 is not lower than the height of the guardrail; and each first barrier machine 1 is connected to the controller 5.

[0026] This embodiment is applicable to the scenario of single-sided road closure, and can realize single-sided road closure for the left or right side of the road. In the prior art, when road closure is required, it is necessary to manually place cone barrels, warning signs and other structures at the set position in front of the highway tunnel to close the road. However, the speed of vehicles on the highway is relatively fast, and there are great safety hazards in the process of road closure. For this reason, this embodiment proposes to replace the cone barrels with a barrier machine to close the road. On the one hand, the barrier machine can realize remote control and automatically close the road according to the road closure instruction. There is no need for manual operation on the highway, which realizes intelligent operation and reduces risks. On the other hand, compared with placing cone barrels, the use of barrier machines to close the road greatly improves the efficiency of road closure.

[0027] The first barrier machine used in this embodiment is preferably a horizontally rotating barrier machine, whose barrier rotates horizontally. When normal vehicles pass, the barrier is parallel to the guardrail and will not affect the passage of vehicles. When the lane needs to be closed, the barrier of the barrier machine rotates horizontally against the driving direction to a direction perpendicular to the guardrail and the lane to achieve road closure.

[0028] The first barrier machine has different lengths of barriers, wherein the barrier closer to the tunnel entrance is longer and the barrier farther away from the tunnel entrance is shorter, thereby providing a buffer and guidance effect to vehicles when the road is closed.

[0029] For single-sided road closures, there are two situations: right-side road closures and left-side road closures. For left-side road closures, that is, when the left express lane is closed, at least the leftmost lane needs to be closed. Here, the leftmost lane is called the first lane on the left, and the second lane from the left is called the second lane on the left. Figure 1 This is a schematic diagram of the left-side road closure. Since there is still a certain distance from the first lane on the left to the dividing guardrail in the middle of the road, the length of the guardrail of the first barrier machine farthest from the tunnel entrance must be at least greater than the distance between the guardrail on the left side of the road and the first lane on the left. The length of the guardrail of the first barrier machine close to the tunnel entrance gradually increases. The length of the guardrail of the first barrier machine closest to the tunnel entrance can be designed to be greater than the distance between the guardrail on the left side of the road and the second lane on the left, that is, when the guardrail of the first barrier machine is vertical, the second lane on the left can be closed, thereby meeting the road closure requirements under various construction conditions.

[0030] For the right side road closure, similarly, at least the rightmost lane needs to be closed. Therefore, the length of the barrier of the first barrier machine closest to the tunnel entrance must be sufficient to close the first lane on the right side. Considering that there is also an emergency lane on the right side of the road, the length of the barrier can be designed to be greater than, equal to, or slightly less than the distance between the guardrail on the right side of the road and the left edge of the first lane on the right side. The length of the barrier of the first barrier machine farthest from the tunnel entrance can be designed to be equal to the distance between the guardrail on the right side of the road and the first lane on the right side (right edge), that is, it can close the emergency lane.

[0031] In order to achieve the warning function, a yellow light arrow is set on the railing of the first barrier machine. When the railing is rotated to be perpendicular to the road, the yellow light arrow faces the direction of the oncoming vehicle. When the first barrier machine is located on the right side of the road, the railing has a yellow light arrow pointing to the left; when the first barrier machine is located on the left side of the road, the railing has a yellow light arrow pointing to the right. The yellow light arrow on the railing is usually off. When it is rotated to a vertical position, the yellow light arrow lights up and flashes or works dynamically.

[0032] The first barrier machine is installed on the basis of the outer side of the guardrail, including a railing, a machine cap, and a chassis. The material of the machine cap and the chassis is 2mm thick Q235 steel plate, and the surface is phosphating spray-coated; the color of the machine cap and the chassis is orange. The inside of the chassis has a structure that drives the railing to rotate, such as a rotatable stalled motor, a gear reducer, and a transmission mechanism. The rotatable stalled motor and the gear reducer adopt an integrated maintenance-free design. The machine cap is set on the upper part of the chassis, and the railing is rotatably connected to the upper part of the machine cap. The railing is made of aluminum alloy material, the surface is oxidized and spray-coated, the rod body is white, and the surfaces on both sides of the rod body are affixed with red engineering-grade reflective film. The first barrier machine can be realized by using existing technology, which will not be repeated here.

[0033] The system is powered by electricity from the nearest substation, and the system passes through the tunnel and the pipeline. The system controller 5 is set in the nearest substation 6, and the control line uses RS485. When the transmission distance exceeds 800 meters, the control signal is transmitted by optical fiber and connected to each first barrier machine. The controller is connected to the switch 8 through the network port and linked to the monitoring center 7 of the tunnel management station.

[0034] The controller can use the embedded controller STM32F107, which integrates MAC controller, CAN bus controller and multi-channel serial communication interface, and integrates a complete motor control module, which can flexibly control the motor operation. In order to realize the fast operation of the barrier machine and prevent the impact of the position, the Hall sensor is used to detect the stroke, and the encoder interface integrated in the STM32 can suppress the jitter during rotation.

[0035] When the construction unit needs to overhaul, it sends a request to the monitoring center, which reports to the traffic department. After approval of the road closure, the monitoring room issues a road closure order. After the client in the substation receives the order, the controller activates the barrier machine.

[0036] Embodiment 2

[0037] This embodiment provides a tunnel intelligent emergency traffic control system, which is suitable for double-side road closures, such as Figure 2 As shown, it includes a plurality of second barrier machines 3 arranged on the outer side of the central guardrail of the road, a plurality of third barrier machines 4 arranged on the outer side of the right side of the road, and a controller 5. The second barrier machines are arranged at a third set distance from the tunnel entrance, and a fourth set distance is set between each second barrier machine; the third barrier machines are arranged at a fifth set distance from the tunnel entrance, and a sixth set distance is set between each third barrier machine; the railing lengths of the second barrier machines and the third barrier machines gradually decrease with increasing distances from the tunnel entrance; the height of the railing of the second barrier machine is not lower than the height of the central guardrail of the road; the height of the railing of the third barrier machine is not lower than the height of the guardrail on the right side of the road; each of the second barrier machines and each of the third barrier machines are connected to the controller.

[0038] The difference between this embodiment and the first embodiment is that this embodiment is applicable to single-side and / or double-side road closures and is more suitable for actual application scenarios. The working principle of the system is the same as that of the first embodiment. Barrier machines are set on both sides of the road. When single-side and / or double-side road closures are required, a certain number of second barrier machines and / or third barrier machines can be controlled according to actual needs to achieve road closure of one and / or multiple lanes.

[0039] The following takes an actual application scenario as an example to specifically introduce the configuration method of the system provided by this embodiment.

[0040] Take the road conditions before a tunnel on a highway as an example. Figure 2 As shown, the highway grade is a two-way six-lane expressway, with a design speed of 100km / h, a lane width of 3.5 meters, a distance of 0.5 meters between the central guardrail and the first lane on the left, and a width of 3.5 meters for the emergency lane on the right side of the road. The emergency lane gradually narrows 100 meters from the tunnel entrance.

[0041] There are 5 second barrier machines 3 on the left side of the road, and the distance between each barrier machine is 40 meters. The first second barrier machine is laid out 240 meters from the tunnel entrance, with a barrier length of 1.5 meters, closing 1.0 meters of the first lane on the left; 200 meters from the tunnel entrance, the second second barrier machine is laid out, with a barrier length of 2.5 meters, closing 2.0 meters of the first lane on the left; 160 meters from the tunnel entrance, the third second barrier machine is laid out, with a barrier length of 3.5 meters, closing 3.0 meters of the first lane on the left; 120 meters from the tunnel entrance, the fourth second barrier machine is laid out, with a barrier length of 5.0 meters, closing 1.0 meters of the second lane on the left; 80 meters from the tunnel entrance, the fifth second barrier machine is laid out, with a barrier length of 7.0 meters, closing 3.0 meters of the second lane on the left.

[0042] The number of third barrier machines 4 on the right side of the road is 4, and the distance between each barrier machine is 40 meters. The first third barrier machine is laid out 240 meters from the tunnel entrance, with a barrier length of 3.5 meters, and only the emergency lane is closed; 200 meters from the tunnel entrance, the second third barrier machine is laid out, with a barrier length of 4.5 meters, and the right emergency lane and the first lane on the right are closed by 1.0 meters; 160 meters from the tunnel entrance, the third third barrier machine is laid out, with a barrier length of 5.5 meters, and the right emergency lane and the first lane on the right are closed by 2.0 meters; 120 meters from the tunnel entrance, the fourth third barrier machine is laid out, with a barrier length of 7.0 meters, and the right emergency lane and the first lane on the right are closed by 3.5 meters.

[0043] This arrangement can meet the needs of closing three lanes. According to actual needs, you can choose to close the first lane on the left, the first and second lanes on the left, the first lane on the right, or all three lanes.

[0044] The system is suitable for maintenance and construction of extra-long tunnels and tunnel groups. Especially when the tunnel substation is located in the median strip or a cross-hole substation is set. Since the substation is located on the left side of the driving direction, and the left side is the overtaking lane, the vehicle travels at a high speed, and there are serious safety hazards during daily inspections. Take the left-side road closure as an example to describe the working method of the system. When we need to stop and inspect the equipment on the left side of the tunnel, the monitoring center issues a left-side closure command, and the controller controls the second barrier machine on the left side of the road to move, starting from the barrier machine farthest from the tunnel entrance on the left side, and moves in sequence at intervals of 1 second. In addition, the incoming vehicle can also be monitored through structures such as cameras. When a vehicle is detected, no action is performed. The road closure action will only be performed when no vehicle is detected. When the inspection is completed, starting from the barrier machine closest to the tunnel entrance on the left side, the barriers of each barrier machine are retracted to their original positions in sequence at intervals of 1 second.

[0045] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
