Example 1
Referring to fig. 1, a schematic diagram of a road-based curve coming early warning device in the present invention is shown, the device includes a first camera, a second camera, a third camera 5, a monitoring component, an early warning component, a first protection component, a second protection component, a controller 2 and a mounting board 1, wherein the third camera, the early warning component, the first protection component, the second protection component and the controller 2 are all mounted on the mounting board 1; the first camera is used for collecting first vehicle information at one entrance of a curve and uploading the first vehicle information to the controller, the second camera is used for collecting second vehicle information at the other entrance of the curve and uploading the second vehicle information to the controller 2, the controller 2 judges whether vehicles exist at the two entrances of the curve or not based on the first vehicle information and the second vehicle information, and if the vehicles exist at the two entrances of the curve, the controller 2 controls the early warning component to carry out vehicle meeting early warning; the third camera 5 is configured to acquire obstacle information at a curved road surface to obtain first information and upload the first information to the controller 2, where the controller 2 determines whether an obstacle exists on the curved road surface based on the first information, and if it is determined that the obstacle exists on the curved road surface, the controller 2 controls the early warning component to perform obstacle early warning; the monitoring component is used for acquiring falling stone information of mountain bodies on two sides of a road surface to obtain second information and uploading the second information to the controller 2, the controller 2 judges whether the mountain bodies have falling stone risks based on the second information, and if the falling stone risks are judged to exist, the controller 2 controls the early warning component to perform falling stone early warning and controls the first protection component to start protection or controls the second protection component to start protection.
The models of the first camera, the second camera, the third camera 5 and the controller 2 can be selected according to actual requirements, and the invention is not particularly limited. The first camera and the second camera are arranged at two inlets of the curve and used for monitoring whether vehicles appear at the inlets, and the early warning assembly is controlled to carry out vehicle meeting early warning only when vehicles exist at the two inlets of the curve. The third camera 5 is installed on the mounting plate 1 and is used for collecting obstacle information on a curved road surface, for mountain roads, larger or smaller stones often fall onto the road surface, if a driver does not notice the stones on the road surface in the driving process of the vehicle, potential safety hazards such as vehicle slipping are likely to exist, therefore, the controller 2 judges whether the road surface is provided with an obstacle or not through the collected obstacle information, and if the road surface is provided with the obstacle information, the controller 2 controls the early warning component to early warn the driver to decelerate in advance. The monitoring component is arranged on the mountain body on two sides of the highway and is used for collecting the falling stone information of the mountain body, similarly, stone slipping can occur frequently in the mountain highway, if stone slipping occurs when a vehicle passes through a curve highway, larger potential safety hazards can be caused to the passing vehicle, meanwhile, damage can be caused to the early warning device, therefore, the falling stone information is monitored through the monitoring component, and when the falling stone occurrence risk is monitored, the controller 2 controls the early warning component to perform early warning and simultaneously controls the first protection component or the second protection component to perform protection.
The monitoring assembly comprises a plurality of image processors and a plurality of image collectors, wherein the image collectors are used for collecting real-time images of stones on mountain bodies on two sides of a road surface and uploading collected image information at a plurality of moments to the image processors; the image processor is used for acquiring a first coordinate point in a corresponding image of a stone block at a moment t1 and a second coordinate point in a corresponding image of the stone block at a moment t2 based on the image information, t1 is greater than t2, calculating a first distance between the first coordinate point and the second coordinate point and comparing the first distance with a preset distance threshold, when the first distance is greater than the preset distance threshold, the image processor marks the corresponding stone block as a risk stone block and controls the image collector to acquire characteristic information of the risk stone block and upload the characteristic information to the controller 2, the controller 2 acquires first volume information of a part of stone block exposed outside the earth surface of the risk stone block based on the characteristic information of the risk stone block, and when the first volume information is in a first preset range, the controller 2 controls the early warning assembly to perform early warning and controls the first protection assembly to start protection; when the first volume information exceeds the first preset range, the controller 2 controls the early warning component to early warn and controls the second protection component to start protection.
The model numbers of the image collector and the image processor can be selected according to actual requirements, and the invention is not particularly limited. For the time t1 and the time t2, except that t1> t2 is satisfied, and the interval between the time t1 and the time t2 is as small as possible, so that the stone can be monitored as soon as possible when the stone is at risk of sliding down. If the first coordinate point is (0, 5), the second coordinate point is (0, 7), the preset distance threshold is 1, the first distance is 2, and at the moment, the first distance is larger than the preset distance threshold, the stone is marked as a risk stone, the characteristic information of the stone is collected to obtain the volume information of the stone, and the probability of falling of the small stone on a mountain is far larger than that of the large stone, so that the first protection component is designed to protect the small stone, and the second protection component is designed to protect the large stone. Since some of the mountain stones are completely exposed on the ground, the stone can acquire the volume information of the complete stone through the stone characteristic information, but some stones are embedded in the mountain, only part of the stones are exposed on the ground, and the volume information of the stones cannot be directly acquired, but the volume range of the complete stone can be estimated through the volume of the stones exposed on the ground, because loosening and sliding can easily occur when more than half of the stones are exposed on the ground, the volume of the stones exposed on the ground is v1, the complete volume of the stones is v, the volume of the stones embedded in the mountain is v2, v=v1+v2, and v1 < v < 2v1, so the complete volume range of the stones can be estimated through acquiring the volume information of the stones exposed on the ground. When the first volume information is located in a first preset range, the controller 2 controls the early warning component to early warn and controls the first protection component to start protection; when the second volume information exceeds the first preset range, the controller 2 controls the early warning component to early warn and controls the second protection component to start protection.
