Specifically, the total loss is the sum of the first loss and the second loss.
In the embodiment of the application, the terrain information, traffic flow information and weather information of alternative routes are comprehensively considered to simulate factors influencing steel consumption, and meanwhile, vehicle information is combined, so that collision, friction and corrosion in the transportation process are conveniently simulated based on vehicle carrying space distribution information, loading modes, loading quantity and wear coefficients of steel; by establishing a model in a simulation environment and simulating, the real transportation process can be simulated, so that the consumption of steel can be predicted more accurately; meanwhile, as the simulation rate is larger than 1, namely the time flow rate in the simulation environment is faster than the real time, a large amount of simulation can be completed in a short time, and the prediction efficiency is improved.
Further, referring to fig. 2, a simulation model is built in the simulation environment based on the terrain information, the traffic flow information, and the weather information, and specifically may include step S131 (not shown in the figure) -step S134 (not shown in the figure), where:
step S131, building a terrain model corresponding to each sub-road section based on terrain information, wherein the terrain information comprises various terrain types corresponding to each sub-road section and terrain parameters corresponding to the various terrain types.
Specifically, the terrain types at least comprise curves, uphill slopes, downhill slopes and other terrains, and can also comprise highways, province and county roads, national roads and other roads; the terrain parameters for each terrain type include at least length, road surface flatness, and maximum slope, slope direction distribution. Because the topographic information is collected based on the disclosed digital map, the topographic model corresponding to the sub-link can be directly extracted from the digital map as the topographic model of the sub-link.
Step S132, a weather model corresponding to each sub-road section is built based on weather information, wherein the weather information comprises a corresponding relation curve of weather parameters and time of each sub-road section, and the weather parameters comprise weather type, temperature and humidity.
Specifically, the input of the weather model is sampling time, and the output of the weather model is weather parameter determined based on the sampling time and a corresponding relation curve of the weather parameter and time.
Specifically, determining weather parameters of the vehicle model of the transport vehicle passing through any sub-road segment may specifically include: determining the total duration of all the passed sub-road sections of the transport vehicle, and determining the arrival time corresponding to the arrival of the transport vehicle at any sub-road section based on the starting time of the transport vehicle;
and sampling the weather model of any sub-road section based on the sampling frequency of any sub-road section and the arrival time corresponding to the arrival of the transport vehicle at any sub-road section so as to determine weather parameters of the transport vehicle passing through any sub-road section.
And step S133, establishing an interference vehicle model corresponding to each sub-road section based on traffic flow information and terrain information, wherein the traffic flow information comprises the average flow of each sub-road section in a history period.
Specifically, for one sub-section: and establishing an interference vehicle number generator based on the daily average flow curve corresponding to the sub-road section, establishing an interference vehicle distributor based on the terrain type of the sub-road section, and then establishing an interference vehicle model of the sub-road section based on the interference vehicle number generator and the interference vehicle distributor so as to establish an interference vehicle model corresponding to each sub-road section.
Specifically, the disturbance vehicle quantity generator determines the disturbance vehicle quantity based on the sampling frequency of the sub-road section, the disturbance vehicle distributor determines the distribution density of the disturbance vehicles corresponding to each terrain type in the sub-road section based on the disturbance vehicle quantity, and then the disturbance vehicles are arranged based on the distribution density of the disturbance vehicles corresponding to each terrain type; further, an interfering vehicle model corresponding to each sub-road section is established.
Specifically, the interfering vehicles in each terrain type are configured such that the following distance complies with preset driving rules, for example, the following distance is not more than 50m, and the interfering vehicles do not exceed the highest speed per hour defined by the terrain type in each terrain type. The driving rules can be acquired based on road traffic rules of sub-road sections and can be input by a user.
In particular, the distribution density characterizes the number of disturbing vehicles in the road corresponding to the terrain, in fact, since in some terrain types with greater difficulty of passing, the speed-limiting passing of the passing vehicles is required, the distribution density corresponding to the terrain type with greater difficulty of passing is greater. That is, the difficulty of traffic of a terrain type is positively correlated with the distribution density of interfering vehicles in the terrain type in the same sub-section.
More specifically, in one sub-road section, the traffic difficulty of each terrain type is determined based on the terrain parameter of each terrain type, and then the proportion of the disturbance vehicle type in each terrain type to the average traffic flow of the sub-road section is determined based on the traffic difficulty of each terrain type, and then the distribution density of the disturbance vehicles corresponding to each terrain type in each sub-road section is determined.
And step S134, establishing a simulation model based on the terrain model, the weather model and the disturbance vehicle model corresponding to each sub-road section in the simulation environment.
In particular, the simulation environment may employ any one of a Finite Element Analysis (FEA) model, a multi-body dynamics (MBD) model, and a vehicle dynamics model. And adding a corresponding terrain model and an interference vehicle model in the simulation environment, wherein the terrain model is a fixed parameter setting and does not change in the simulation process. The disturbance vehicle in the disturbance model is configured to travel along the path of the sub-road section, and when the disturbance vehicle reaches the end point of the sub-road section, the disturbance vehicle reaching the end point is deleted and regenerated at the start point of the sub-road section.
The weather model is based on a relation curve of weather parameters and time of a corresponding sub-road section as a function, the input result is sampling time in a simulation environment as an independent variable, the output result is the weather parameters obtained by sampling the sub-road section, and the real-time in the simulation environment and the real-time corresponding to the function curve are converted based on simulation rate and then correspond to each other.
Further, the vehicle information is configured in the simulation model to perform simulation, and specifically, the method may include a step of building a vehicle model and a step of configuring the vehicle model.
The step of building a vehicle model may specifically include: acquiring a mechanical collision model of the transport vehicle, and constructing an initial model of the transport vehicle of the vehicle in the mechanical collision model based on vehicle information; acquiring characteristic information of the steel, wherein the characteristic information comprises corrosion speed curves of the steel at different temperatures and different humidities, and determining the exposed area of the steel based on vehicle information; and then adding the characteristic information and the exposed area of the steel material into the initial model to obtain the vehicle model. The vehicle model is configured to adjust a driving state including a driving speed, a braking and an accelerating action based on an output of weather parameters of a sub-section on which the vehicle model is located. Meanwhile, the vehicle model is also configured to conform to the driving rules of the corresponding sub-road sections with the interfering vehicle.
Specifically, a mechanical collision model is determined based on a simulation environment, and a Finite Element Analysis (FEA) model can simulate stress and strain distribution due to vibration, jolt, emergency braking, and the like during transportation by discretizing the geometric shapes of vehicles and steels into a limited number of elements. If a Finite Element Analysis (FEA) model is used as the simulation environment, the model itself is a collision model without the need for additional building of the collision model. If other simulation environments are adopted, a boundary box collision detection (Bounding Box Collision Detection) model can be adopted as the mechanical collision model, and as each object in the boundary box collision detection model is surrounded by a rectangle (in 2D) or a cube (in 3D), whether the object is likely to collide can be rapidly determined by comparing whether the boundary boxes are intersected or not, and the corresponding cube environment is more in accordance with the shape and loading mode of steel materials, so that more accurate simulation results are conveniently obtained.
Specifically, a three-dimensional model of the transport vehicle is built based on vehicle information and configured in the three-dimensional model of the vehicle based on the loading manner of the steel material and the loading amount of the steel material, and the exposed area is obtained by identifying the surface area of the steel material by a detection edge algorithm.
The configuring step of the model specifically may include: the vehicle model is configured to simulate based on the simulation rate of the sub-road segment; the simulation rate of the sub-road segments is determined based on the road class of the sub-road segments, and the simulation rate of the sub-road segments is configured to be in positive correlation with the sampling frequency of the sub-road segments, and the simulation rate of each sub-road segment is greater than 1.
Specifically, the road level of the sub-link characterizes the terrain complexity of the sub-link, and the road level of the sub-link can be preset. The different topography grades of the sub-sections, the slower the simulation rate corresponding to the sub-sections, and further, the lower the sampling frequency of the sub-sections.
For example, for the a road segment and the B road segment, the terrain types of the a road segment are numerous and complex, and thus, the terrain level of the a road segment is higher than that of the B road segment, the simulation rate corresponding to the a road segment may be 7, and the anti-shake rate corresponding to the B road segment may be 10. That is, in the simulation environment, the vehicle model travels for 1 minute in the a segment corresponding to 7 minutes in reality, and the vehicle model travels for 1 minute in the B segment corresponding to 10 minutes in reality. Meanwhile, in the a section, weather parameters and average traffic flow may be acquired every 1 minute, and in the B section, weather parameters and average traffic flow may be acquired every 3 minutes.
In the simulation process, the lower the simulation rate is, the lower the sampling frequency is, and more accurate simulation results are easier to obtain.
