Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0020] The embodiments of the present invention disclose a system for analyzing and selecting the transportation route of a wind turbine tower based on Beidou navigation. As Figure 1 shown, it includes: a multi - level vehicle speed calculation network system for tower - tube transportation, a "Intelligent Transportation" mobile phone APP, and a Beidou satellite system; the Beidou satellite system is respectively connected to the multi - level vehicle speed calculation network system for tower - tube transportation and the "Intelligent Transportation" mobile phone APP; The Beidou satellite system determines the starting point and the sea - entry point of the tower - tube transportation vehicle, determines the transportation departure date according to the weather information, and sends the transportation departure date, the starting point, and the sea - entry point to the multi - level vehicle speed calculation network system for tower - tube transportation and the "Intelligent Transportation" mobile phone APP; The multi - level vehicle speed calculation network system for tower - tube transportation performs predictive analysis based on the historical vehicle speed influence factors of tower - tube transportation vehicles and the associated vehicle speed information to obtain the road with the fastest speed and the most convenient transportation among the roads near the vehicle; the multi - level vehicle speed calculation network system for tower - tube transportation includes three layers of networks, namely, a memory network, an analysis network, and a calculation network; The "Intelligent Transportation" mobile phone APP receives the information from the Beidou satellite system for display and helps the tower - tube transport vehicle select the optimal driving route.

[0021] In a specific embodiment, after determining the starting point and the sea - entry point of the tower - tube transportation vehicle, the relevant sea area's recent weather conditions are understood through the meteorological department, and the date with suitable weather conditions for construction is selected as the departure date, and the time information is transmitted to the multi - level vehicle speed calculation network system for tower - tube transportation and the "Intelligent Transportation" mobile phone APP.

[0022] The multi-level tower barrel transportation vehicle speed calculation network system includes the following three-level networks: The first-level network is a memory network, which imports speed influence factors such as traffic signal durations, the number of bends, road conditions, and pedestrian flows, as well as associated vehicle speed information of the roads passed by tower barrel transportation vehicles in the past into a memory file. The speed influence factors are as shown in Figure 2 ; Using these data, the relationship curve between the average vehicle speed and various influence factors is simulated. This curve is based on real data, can consider human and accidental factors, and the fitted curve is real and reliable; The second-level network is an analysis network, which is interconnected with the Beidou satellite system. It analyzes the speed influence factors of the roads that the tower barrel transportation vehicle may pass by at the departure time and imports them into the memory file in the first network. The third-level network is a calculation network. According to the information recorded in the memory file, it calculates the data in the second-level network and predicts the road with the fastest speed and the most convenient transportation among the roads near the vehicle. The current vehicle speed of the section is predicted in the simulation curve and transmitted to the driver in real time, so as to predict the road with the fastest and most convenient driving for the vehicle in the current and future periods.

[0023] The "Intelligent Transportation" mobile phone APP is combined with 5G Internet communication technology and includes three major modules: The first module realizes the interconnection between the tower barrel transportation vehicle speed calculation network system and the owners of tower barrel transportation vehicles, and informs the owners of the road conditions of the upcoming road and the recommended driving speed; The second module realizes the interconnection between tower barrel transportation vehicles and relevant departments; The third module realizes the disclosure of transportation vehicle information and notifies the relevant information to the owners driving on the road. This invention can help tower barrel transportation vehicles select the optimal driving route faster and more accurately, and improve the transportation efficiency and safety of tower barrel transportation. The schematic diagram of Internet information interconnection is as shown in Figure 4 ;

[0024] In a specific embodiment, the relevant marine meteorological department analyzes the recent weather conditions, which can be divided into three situations: 3-level wind and clear weather - suitable for offshore operations, and this kind of weather should be given priority; 3-5-level wind and suitable weather - the difficulty of offshore operations increases, and this kind of weather should be used as an alternative and cannot be given priority; More than 5-level wind or thunderstorm weather appears - the difficulty of offshore operations is extremely high in this kind of weather and it cannot be selected. Finally, the weather rating result and the suitable departure date are informed to the transportation unit.

[0025] In a specific embodiment, the calculation steps of the first-level network are as follows: This network is responsible for storing data. Through the Beidou system, for different road sections, it statistically analyzes speed-influencing factors such as road conditions, traffic flow, pedestrian flow, and weather conditions, as well as associated speed information, and transmits this data back to the ground via wireless link transmission. In the processing of memory files, the system adopts a relational data model for efficient data aggregation. Among them, each tuple in the two-dimensional table details different vehicle speeds and their corresponding complex road conditions, and the attributes of the table are the various influencing factors that affect vehicle speed. To ensure the accuracy and integrity of the data, the system uses Structured Query Language (SQL) to define and modify the data in the two-dimensional table. At the same time, the system also provides ACID transaction support to ensure the protection of entity integrity, referential integrity, and user-defined integrity during data transmission and processing. These data need to be sorted and recorded in the memory file. The calculation network will fit a curve through the method of least squares approximation. This curve precisely constructs the multivariate function relationship between the average vehicle speed and various influencing factors, forming a multi-dimensional data model , where Y represents the average vehicle speed, and represents various influencing factors. This model can fit the curve of the average vehicle speed changing with various influencing factors, and store these key information into the memory file again, providing strong data support for subsequent transportation decision-making and optimization.

[0026] In a specific embodiment, in the second-level network part of the multi-level tower barrel transportation vehicle speed calculation network system, information such as the duration of road traffic lights, the number of curves, the surrounding conditions of the road, traffic congestion conditions, and pedestrian flow on the monitored road section by the Beidou satellite is transmitted back to the ground through a wireless communication link established with communication equipment on the ground. At the same time, the Beidou communication system is combined with 5G mobile Internet technology to quickly and accurately transmit relevant data of vehicle driving to the calculation hub of the calculation network.

[0027] In a specific embodiment, in the third-level network part of the multi-level tower barrel transportation vehicle speed calculation network system, the data analyzed and transmitted by the Beidou satellite system in the second step is imported into the memory file obtained in the first part, and these data are subjected to skip searching, that is, a larger step size is set first. After determining the data belonging interval, the step size is reduced, and the above operation is repeated within this interval. When the step size is less than a certain value, linear search is performed to obtain the accurate estimated vehicle speed of the current road.

[0028] In a specific embodiment, the APP launched by the Beidou satellite system and 5G Internet has different functional modules according to different clients.

[0029] The first module: applicable to the driver interface of the tower barrel transport vehicle. The driver of the tower barrel transport vehicle can enter the exclusive interface according to the project name and identity verification. The main content of this interface includes the satellite navigation function: this function adopts a multi-system tower barrel transport vehicle speed calculation network system, and the driver can quickly transport the tower barrel according to this system; the quick help function: in view of various emergencies that may be encountered on the road during the driver's transportation process due to the excessive length or diameter of the tower barrel, this function can quickly send its own information and the problems encountered to the relevant departments through digital signal transmission to solve the problems in a timely manner. Among them, the schematic diagram of the driver's end function of the "Intelligent Transportation" mobile APP is as Figure 3 shown.

[0030] The second module: applicable to the interface of relevant departments. This interface is an interface that relevant units can enter, such as traffic units, fire departments, etc. The main functions of this interface include that for traffic units, they can quickly receive the current position of the tower barrel transport vehicle and the intersections that need to be dredged in advance, and at the same time, they can master the position of the transport vehicle in real time, which is convenient for managing road traffic and avoiding traffic jams; for fire departments, through the wireless communication between this APP and the Beidou system, they can master the accident location, and at the same time, through the 5G interconnection technology, they can quickly understand the scale of the accident, which is convenient for making relevant preparations.

[0031] The third module: applicable to the interface of other vehicles and pedestrians on the road. An interface that vehicles driving on relevant roads and pedestrians on the roadside can enter. The main content of this interface includes the current position reporting function of the tower barrel transport vehicle: this function combines the Beidou satellite navigation system, and other drivers and pedestrians can see the road where the current transport vehicle is located and the road to be traveled next according to this function module, and pedestrians can choose the next navigation route according to their own needs; the quick alarm function: since the probability of accidents occurring during the transportation of tower barrels and large-diameter pile foundations is relatively high, other vehicles and pedestrians on the road can quickly report to the authorities through the data network.

[0032] The present invention introduces more specific embodiments for further illustration.

[0033] This example adopts a system for analyzing and selecting the transportation route of a wind turbine tower barrel based on Beidou navigation provided by the present invention. The specific process steps are as follows: Before the transportation starts, determine the starting point and the sea entry point, and input the positions of the two points into the "Intelligent Transportation" mobile APP. This APP is connected to the Beidou satellite system through the 5G network, and the Beidou system will transmit the weather conditions of the construction sea area to the APP and display the recommended construction date and the recommended departure time.

[0034] During the data transmission process, the data language is defined and modified by the structured query language. At the same time, ACID transaction support is provided to ensure the entity integrity, referential integrity, and user-defined integrity of the data during the transmission and processing process.

[0035] After determining the departure time, the time information will be transmitted through the Internet to relevant departments in the area, such as the traffic management department.

[0036] Before departure, the driver logs in to the mobile APP in the present invention. After verifying the identity information, the driver enters the driver interface and can observe the predicted vehicle speeds and road conditions of different sections calculated by the network computing system. The driver selects the route to be traveled next. The current route of the driver and the selected route next will be transmitted to the whole network through the 5G network. The drivers and pedestrians traveling on the selected section of the driver will receive a reminder, and other vehicles on the road can choose their own routes according to their own situations to avoid being affected by the oversized tower barrel transport vehicle and complex transportation.

[0037] During the driving process on the road, the driver can also learn the information of the next section to be traveled and the recommended vehicle speed through the APP, which is convenient for the driver to make judgments in advance.

[0038] The traffic management department can also observe the current location of the vehicle through the APP, which is convenient for it to manage road traffic and avoid road congestion and various emergencies.

[0039] When an emergency occurs, the driver can contact relevant departments in time through the APP function. The APP is interconnected with multiple parties and records the vehicle conditions and location at any time. It can facilitate the driver to obtain help in time and quickly solve problems in case of vehicle jams, traffic accidents, fires, sudden diseases of drivers, vehicle failures and various situations that may occur on the road, so as to avoid wasting public resources.

[0040] During the driving process, the owners of other vehicles can also obtain help through the APP. For example, if the driver of the tower barrel transport vehicle has a sudden illness, the driver has a traffic accident or the vehicle catches fire. Since the APP is interconnected with Beidou, it can facilitate relevant departments to know the situation and the size of the accident in time.

[0041] During the driving process, the construction party can observe the vehicle location in real time, which is convenient for construction preparation.

[0042] The present invention conducts data statistics through the Beidou system. After being transmitted to the ground network computing system, it selects a route for the offshore wind turbine tower barrel transport vehicle by predicting the real-time vehicle speed. At the same time, the present invention uses the 5G interconnection system to enable multi-party interconnection of transport vehicles, relevant departments, road vehicles, construction units, etc. The present invention has the following advantages: Relying on the Beidou Satellite Navigation System, the present invention has achieved unprecedented precision and efficiency. The Beidou System transmits real-time monitoring data from satellites to the ground in real time, and transmits the data to the computing center through wireless devices, realizing seamless data docking. Its centimeter-level positioning accuracy and more than 99% availability globally ensure the accuracy, extensiveness, and rapidity of data collection. Especially in the Asia-Pacific region, the positioning accuracy of the Beidou System is better than 5 meters. Combined with advanced technologies, its positioning accuracy has reached the centimeter level, and both the speed measurement accuracy and the timing accuracy are at the global leading level. This global networking form, with the Beidou System deploying 30 satellites, provides a solid guarantee for the security and reliability of data collection.

[0043] The data of the present invention is managed using the Structured Query Language (SQL) and supports ACID transactions to ensure data integrity and consistency. Through entity integrity constraints, referential integrity constraints, and user-defined integrity constraints, the system realizes rigorous and reliable control in data management, providing a strong guarantee for the accurate execution of calculations.

[0044] Based on the driving data of historical transport vehicles on this route, the present invention simulates the influence curves of different vehicle conditions and road conditions on the average vehicle speed and makes real-time predictions. This prediction method based on big data not only ensures the reliability of the data but also the sufficiency of the samples, making the predicted vehicle speed more accurate and providing precise guidance for the transportation process.

[0045] The present invention uses 5G Internet technology to achieve efficient interconnection among three parties. With its propagation rate of up to 20 Gbps, 5G technology ensures the speed and accuracy of information dissemination. The system also designs diverse APP interfaces for different user groups, realizing fast and accurate information transmission and interaction, effectively avoiding potential problems, and providing quick and effective solutions after problems occur. Compared with the 4G network, the 5G network is 10 to 100 times faster in transmission speed, with a latency of less than 1 millisecond, and its wider coverage also provides stronger support for the system.
