[0048] The safety risk brought by the large-scale of ships to the river-crossing bridge is increasing, especially for the inland high-grade waterway. Due to the busy water traffic, large ship load, and complex navigation environment, the safety hidden danger of ship and bridge collision is particularly prominent. In view of the relatively large ship load and low driving flexibility, once colliding with the bridge, it is easy to cause the bridge damage, even collapse and other serious accidents.

[0049] In view of this, the present application provides a river collision avoidance system and a control method thereof, Figure 1 and Figure 2 An embodiment of the river collision avoidance system provided by the present application, Figure 3 An embodiment of the flowchart of the control method of the river collision avoidance system.

[0050] Referring to Figure 1 , the ship sails along the first direction on the waterway, the river collision avoidance system 100 includes a collision avoidance structure 1, a warning mechanism, a detection mechanism and a control device, the collision avoidance structure 1 is arranged in the waterway and located on one side of the pier, the collision avoidance structure 1 is used to protect the pier; the warning mechanism is used to send a warning to the ship; the detection mechanism is used to detect the actual distance value between the ship and the collision avoidance structure 1; the control device is electrically connected with the warning mechanism and the detection mechanism, the control device includes a memory, a processor and a control program of the river collision avoidance system 100 stored in the memory, and the processor executes the control program of the river collision avoidance system 100 to realize the steps of the control method of the river collision avoidance system 100.

[0051] In the present application, the anti-collision structure 1 is arranged on one side of the bridge pier in the waterway, and can passively bear the impact to protect the bridge pier. The detection mechanism can be a distance sensor arranged on the anti-collision structure 1 to face the side of the waterway, so as to detect the actual distance value of the ship. When the actual distance value is less than or equal to the warning distance value, the warning mechanism issues a warning to remind the driver to deviate in advance, or to be about to collide with the anti-collision structure 1, and to pay attention to the safety preparation of the driver.

[0052] Specifically, the anti-collision structure 1 is arranged close to the side of the waterway as a mounting surface. The river anti-collision system 100 further comprises a guide member 2 arranged on the mounting surface and movable in a second direction intersecting the first direction, which is used to assist the ship to deviate. When the ship deviates close to the mounting surface, the guide member 2 is movable in the second direction towards the waterway to push the ship away from the mounting surface, whether the driver has deviated in advance or not, so as to passively deviate the ship or assist the ship to deviate. In this way, the probability of the ship colliding with the anti-collision structure 1 is reduced, and the ship can pass through the waterway more smoothly.

[0053] More specifically, in the present embodiment, the guide member 2 comprises two movable rods 21 and a roller 22. Each movable rod 21 comprises a first end 211 and a second end 212 oppositely distributed. The two first ends 211 are hinged to each other, and the two second ends 212 are arranged in the first direction and hinged to the mounting surface or slidably mounted on the mounting surface in the first direction. The roller 22 is rotatably mounted at the hinge of the two first ends 211, and the axis of the roller 22 extends upward and downward. When the two second ends 212 are close to each other, the roller 22 moves towards the waterway, and at this time the roller 22 abuts against the surface of the ship, and during the movement of the two second ends 212 close to each other, the roller 22 rolls on the surface of the ship and pushes the ship away from the mounting surface. In this way, the ship can be gently pushed away from the mounting surface to achieve the effect of guiding the deviation, and the surface of the ship is not damaged. When the two second ends 212 are away from each other, the distance between the two movable rods 21 and the mounting surface is reduced, so that the ship does not interfere with the guide member 2 when it normally travels.

[0054] In order to enable one of the second ends 212 to slide in the first direction, the mounting surface is provided with a sliding groove 111 extending in the first direction, and the second end 212 is hingedly provided with a sliding block 23 which is slidingly installed in the sliding groove 111, so that when there is no need for guiding, the two second ends 212 are away from each other, and the two movable rods 21 can be completely attached to the mounting surface to avoid interference with the ship as much as possible.

[0055] It should be noted that the specific hinged structure of the two first ends 211 is not limited, and in the embodiment, the two first ends 211 are provided with rotation holes which are oppositely arranged and extend in the up-down direction, and the guide member 2 further comprises a rotating shaft 24 which is arranged through the two rotation holes, and the upper end of the rotating shaft 24 is provided with a cap portion which has a length extending in the horizontal direction greater than the diameter of the rotation hole, so that the rotating shaft 24 can be prevented from being pulled out of the two rotation holes.

[0056] In the embodiment, the roller 22 comprises a connecting frame 221 and a wheel body 222, the connecting frame 221 extends in the up-down direction, and the upper end of the connecting frame 221 is connected to the lower end of the rotating shaft 24; the axis of the wheel body 222 extends in the up-down direction, and the wheel body 222 is rotationally installed at the lower end of the connecting frame 221; in this way, since the ship body is arranged to be tapered from top to bottom, the position of the roller 22 is correspondingly arranged at the lower side of the ship body, so that the guide member 2 can be protected from being damaged by the ship.

[0057] Based on the above structure, please refer to Figure 3 The application further provides a control method of the riverway anti-collision system 100, comprising the following steps:

[0058] S10, acquiring ship state information;

[0059] S20, determining a corresponding warning distance parameter according to the ship state information;

[0060] S30, acquiring an actual distance value between the ship and the anti-collision structure 1 measured by the detection mechanism;

[0061] S40, comparing the actual distance value with the warning distance parameter, and controlling the warning mechanism to work according to the comparison result to warn the ship.

[0062] In the technical solution of the present application, the ship state information is first obtained, then the warning distance parameter corresponding to the ship is determined according to the ship state information, then the actual distance value between the ship and the anti-collision structure 1 measured by the detection mechanism is obtained, then the actual distance value is compared with the warning distance parameter, and the warning mechanism is controlled to work according to the comparison structure to warn the ship; in this way, different warning distance parameters are determined flexibly according to different ship state information, reminding the driver to make a deviation adjustment in advance to avoid the ship colliding with the anti-collision structure 1.

[0063] In the present embodiment, the ship state information includes ship passage information and / or ship surrounding environment information. In order to determine the warning distance parameter, the ship passage information and the ship surrounding environment information can be obtained before the ship enters the channel, and the final warning distance parameter is determined by referring to the ship passage information and the ship surrounding environment information.

[0064] Specifically, the ship passage information includes the current driving speed and the maximum width size of the ship, and the ship surrounding environment information includes the wind direction, the wind speed and the water flow speed. The hydrological monitoring module, the meteorological monitoring module and the camera can be set before the ship sails in the channel, the water flow speed is measured by the hydrological monitoring module, the wind speed and the wind direction are obtained by the meteorological monitoring module, and the current driving speed and the maximum width size of the ship are obtained by the camera measurement.

[0065] Specifically, the warning mechanism includes a display lamp and a whistle; the warning distance parameter includes a first warning distance value and a second warning distance value, and the first warning distance value is greater than the second warning distance value.

[0066] The step S40 includes:

[0067] S41, when the actual distance value is less than or equal to the first warning distance value and greater than the second warning distance, the display lamp is controlled to be turned on to warn the ship to deviate from the sailing route;

[0068] S42, when the actual distance value is less than or equal to the second warning distance value, the whistle is controlled to be turned on to warn the ship that it is in a dangerous position.

[0069] When the ship is sailing, when the actual distance value is less than or equal to the first warning distance value and greater than the second warning distance value, the display lamp is turned on to remind the driver to pay attention to the sailing route and reduce the sailing speed appropriately, which is easy to collide with the anti-collision structure 1; when the actual distance is less than the second warning distance value, the whistle is controlled to be turned on, and at this time the display lamp is still turned on to remind the driver that the ship is in a dangerous position and needs to deviate immediately to avoid the anti-collision structure 1.

[0070] More specifically, the ship sails in a first direction in a waterway, the riverway anti-collision system 100 comprises a guide 2 arranged on the side of the anti-collision structure 1 facing the waterway and movable in a second direction intersecting the first direction; the ship state information comprises a current sailing speed of the ship, and the early warning distance parameter further comprises a third early warning distance value smaller than the second early warning distance value.

[0071] The step S42 further comprises:

[0072] S43, acquiring the current sailing speed;

[0073] S44, when the actual distance value is smaller than or equal to the third early warning distance value, comparing the current sailing speed with a preset speed, and controlling the guide 2 to work according to the comparison result to guide the ship.

[0074] When the actual distance is smaller than the third early warning distance value, it proves that the ship has not completely deviated or is about to collide with the anti-collision structure 1, so the current sailing speed needs to be acquired for comparison, and the guide 2 is controlled to work.

[0075] Further, the step S44 comprises:

[0076] S441, when the current sailing speed is smaller than or equal to the preset speed, controlling the guide 2 to move towards the waterway to push the ship body;

[0077] When the current sailing speed is greater than the preset speed, the guide 2 is controlled to move towards the anti-collision structure 1 to abut against the anti-collision structure 1.

[0078] When the current sailing speed is greater than the preset speed, the impact force borne by the guide 2 is greater than its maximum bearing load, which proves that even when the guide 2 moves towards the waterway, it cannot effectively guide the ship and may damage the guide 2 and the ship.

[0079] The above only describes the preferred embodiments of the present application, and does not limit the patent scope of the present application, and any equivalent structural transformation made under the inventive concept of the present application, or direct / indirect application in other related technical fields is included in the patent protection scope of the present application.
