[0051] Example 1

[0052] like Figure 1 FIG. 1 is a flow chart of an overlong piece transportation safety assessment method provided in an embodiment of the present application. The overlong piece transportation safety assessment method provided in an embodiment of the present application includes the following steps:

[0053] Step S101, obtaining a preset transport route of an over-length transport vehicle, vehicle size parameters, and size parameters of the over-length transport vehicle.

[0054] Specifically, the overlong piece transport vehicles are all vehicles with steering function on the rear wheels. The overlong piece transport vehicles are composed of a tractor and a long wheelbase trailer. The long wheelbase trailer is used to load overlong pieces, so the vehicle size parameters include the tractor size parameters and the long wheelbase trailer size parameters. The preset transportation route, vehicle size parameters and size parameters of the overlong pieces to be transported are obtained through the "Internet of Transportation + Government Service Integration" platform or directly provided by the transportation company. Ensuring accurate vehicle size parameters and size parameters of the overlong pieces to be transported can accurately assess the safety of overlong piece transport vehicles on the preset transportation routes, reduce the possibility of traffic accidents, and improve the work efficiency of overlong piece transportation operations.

[0055] Step S102, exploring the preset transportation route to obtain route linear parameters and obstacle environment parameters.

[0056] Specifically, before transporting the over-long items, a field survey is conducted on the preset transportation route. The specific road survey device is not limited here, such as a road survey vehicle and a drone. The route linear parameters refer to the road parameters of the preset transportation route. The linear parameters include ramp radius and road width. The obstacles refer to objects that may affect the transportation safety of over-long items transport vehicles on the transportation route, which are not limited here, such as bridge piers, billboard columns, and high excavation slopes.

[0057] Step S103, calculating the maximum total length of the vehicle and cargo, the minimum road width and the minimum ground clearance of the cargo of the overlong cargo transport vehicle on the preset transport route according to the vehicle size parameters, the size parameters of the overlong cargo to be transported, the route linear parameters and the obstacle environment parameters.

[0058] The step of calculating the maximum total length of the vehicle and cargo, the minimum road width and the minimum ground clearance of the cargo of the overlong cargo transport vehicle on the preset transport route according to the vehicle size parameters, the size parameters of the overlong cargo to be transported, the route linear parameters and the obstacle environment parameters comprises:

[0059] Calculating the maximum total length of the vehicle and cargo according to the vehicle size parameters, the size parameters of the overlong items to be transported, the route linear parameters and the obstacle environment parameters;

[0060] The calculation formula for the maximum total length of the vehicle and cargo is:

[0061] ,in, is the length of the tractor head of the over-length transport vehicle, R is the ramp radius of the preset transport route, h is the effective road width of the preset transport route, D is the width of the trailer board, It is the distance from the ramp outer guardrail obstacle to the ramp outer guardrail.

[0062] It can be understood that the 0.25 in the calculation formula of the maximum total length of the vehicle and cargo is the safety width of 0.25m reserved on both sides of the ramp.

[0063] The step of calculating the maximum total length of the vehicle and cargo, the minimum road width and the minimum ground clearance of the cargo of the overlong cargo transport vehicle on the preset transport route according to the vehicle size parameters, the size parameters of the overlong cargo to be transported, the route linear parameters and the obstacle environment parameters comprises:

[0064] Calculating the minimum road width according to the vehicle size parameters, the size parameters of the overlong piece to be transported, the route linear parameters and the obstacle environment parameters;

[0065] The calculation formula of the minimum road width is:

[0066] , where R is the ramp radius of the preset transportation route, h is the effective road width of the preset transportation route, D is the width of the trailer board, and L is the total length of the vehicle for transporting oversized items. It is the length of the tractor head of the vehicle used to transport extra-long pieces.

[0067] It can be understood that the 0.5 in the calculation formula of the minimum road width is a reserved safety width of 0.5 m.

[0068] The step of calculating the maximum total length of the vehicle and cargo, the minimum road width and the minimum ground clearance of the cargo of the overlong cargo transport vehicle on the preset transport route according to the vehicle size parameters, the size parameters of the overlong cargo to be transported, the route linear parameters and the obstacle environment parameters comprises:

[0069] Calculating the minimum ground clearance of cargo based on the vehicle size parameters, the size parameters of the overlong piece to be transported, the route linear parameters, and the obstacle environment parameters;

[0070] The calculation formula for the minimum distance of the cargo from the ground is:

[0071] ,in, The maximum height that the fulcrum of the over-length transport vehicle can be lifted. It is the distance from the ground to the rear of the over-length item on the transport vehicle. is the length of the overlong piece to be transported, The length from the front end to the fulcrum of the extra-long piece to be transported. is the length from the rear wheel of the trailer to the tail of the extra-long piece, and i is the maximum longitudinal slope of the ramp.

[0072] It can be understood that the 0.1 in the calculation formula for the minimum distance of the cargo from the ground is a reserved safety height of 0.1m.

[0073] See also Figure 2 , Figure 3 and Figure 4 , Figure 2 A schematic diagram of the limit state and related parameters of an over-length transport vehicle provided in an embodiment of the present application, Figure 3 A schematic diagram of lifting an over-long piece transport vehicle provided in an embodiment of the present application, Figure 4 A schematic diagram of an over-long piece transport vehicle going uphill provided in an embodiment of the present application.

[0074] Specifically, the study shows that when the front of the tractor of the over-long cargo transport vehicle is close to the outer guardrail of the ramp, and the body of the vehicle is close to the inner guardrail of the ramp, the total length of the vehicle and cargo under this limit state is the maximum total length of the vehicle and cargo that the over-long cargo transport vehicle can safely pass through the ramp. During the driving process of the over-long cargo transport vehicle, the rear wheel angle is adjusted so that the over-long cargo transport vehicle can always maintain the limit state and safely exit the ramp.

[0075] Furthermore, when the overlong piece transport vehicle is in extreme transport state, the minimum road width required for the overlong piece transport vehicle to transport safely on the preset transport route is calculated through the vehicle size parameters, the size parameters of the overlong piece to be transported, the route linear parameters and the obstacle environment parameters.

[0076] It can be understood that when an over-long piece transport vehicle is traveling on a preset transport route and there is an uphill section, the over-long pieces will sag to a certain extent. By calculating the minimum ground clearance of the goods required by the over-long piece transport vehicle on the preset transport route through the vehicle size parameters, the size parameters of the over-long piece to be transported, the route linear parameters and the obstacle environment parameters, it can be assessed whether the over-long piece will hit the road surface facilities during the uphill process and whether there is a risk of bottoming out.

[0077] Step S104, evaluating the transportation safety of the overlong piece transport vehicle on the preset transportation route according to the preset transportation route, the vehicle size parameters, the size parameters of the overlong piece to be transported, the maximum total length of the vehicle and cargo, the minimum road width and the minimum ground clearance of the cargo.

[0078] The step of evaluating the transportation safety of the overlong piece transport vehicle on the preset transportation route according to the preset transportation route, the vehicle size parameters, the size parameters of the overlong piece to be transported, the maximum total length of the vehicle and cargo, the minimum road width and the minimum ground clearance of the cargo comprises:

[0079] The effective road width is obtained according to the preset transport route, and the total length of the vehicle and cargo and the minimum distance of the cargo from the ground are obtained according to the vehicle size parameters and the size parameters of the overlong cargo to be transported;

[0080] When the total length of the vehicle and cargo is less than the maximum total length of the vehicle and cargo, the effective road width is greater than the minimum road width, and the minimum ground clearance of the cargo is greater than 0, it is determined that the overlong cargo transport vehicle can be safely transported on the preset transport route.

[0081] The step of evaluating the transportation safety of the overlong piece transport vehicle on the preset transportation route according to the preset transportation route, the vehicle size parameters, the size parameters of the overlong piece to be transported, the maximum total length of the vehicle and cargo, the minimum road width and the minimum ground clearance of the cargo also includes:

[0082] When the total length of the vehicle and cargo of the overlong piece transport vehicle is greater than the maximum total length of the vehicle and cargo, or the effective road width of the preset transport route is less than the minimum road width, or the minimum ground clearance of the cargo is less than 0, it is determined that the overlong piece transport vehicle cannot be transported safely on the preset transport route;

[0083] When it is determined that the over-length transport vehicle cannot be transported safely on the preset transport route, an adjustment suggestion is generated.

[0084] The adjustment suggestions include changing the transport vehicle, changing the transport route and adjusting the loading location of oversized pieces.

[0085] Specifically, the maximum total length of the overlong cargo transport vehicle on the preset transport route, the minimum road width, the minimum distance of the cargo from the ground, the vehicle size parameters and the size parameters of the overlong cargo to be transported are used to evaluate whether the overlong cargo transport vehicle can travel safely on the preset transport route. When the evaluation result is that it can be transported safely, the vehicle transportation safety is guaranteed and the work efficiency is improved. When the evaluation result is that it cannot be transported safely, suggestions for changes are made to the overlong cargo transport vehicle, the transport route and the cargo loading position, and the staff can make adjustments based on the suggestions until the evaluation result is that it can be transported safely.

[0086] The method for evaluating the safety of over-long piece transportation provided in the embodiment of the present application obtains a preset transportation route, vehicle size parameters and size parameters of over-long pieces to be transported of an over-long piece transportation vehicle, explores the preset transportation route to obtain route linear parameters and obstacle environment parameters, calculates the maximum total length of the vehicle and cargo, the minimum road width and the minimum ground clearance of cargo of the over-long piece transportation vehicle in the preset transportation route according to the vehicle size parameters, the size parameters of the over-long pieces to be transported, the route linear parameters and the obstacle environment parameters, and evaluates the transportation safety of the over-long piece transportation vehicle in the preset transportation route according to the preset transportation route, the vehicle size parameters, the size parameters of the over-long pieces to be transported, the maximum total length of the vehicle and cargo, the minimum road width and the minimum ground clearance of cargo. Compared with the prior art, the method can accurately evaluate the safety of the preset transportation route based on the rear-wheel steering function of the over-long piece transportation vehicle, and can promptly propose changes to the transportation vehicle, transportation route or adjustment of the over-long piece loading position for transportation plans that cannot safely pass through the preset transportation route, thereby improving the safety, scientificity and convenience of over-long piece transportation.
