[0043] Example 1

[0044] A tobacco transportation scheme evaluation method based on Beidou grid code includes the following steps:

[0045] Establish tobacco storage warehouses and tobacco delivery receiving points; divide tobacco delivery areas, which include tobacco storage warehouses, tobacco delivery receiving points and surrounding areas;

[0046] Obtaining terrain information and meteorological information of the tobacco distribution area, and storing the obtained terrain information and meteorological information respectively; dividing and encoding the tobacco distribution area into Beidou grids, and associating the Beidou grid code with the terrain information and meteorological information;

[0047] Establish a three-dimensional map model based on Beidou grid code, terrain information and meteorological information;

[0048] Obtain tobacco delivery orders and three-dimensional map models; plan delivery routes based on the tobacco delivery orders and three-dimensional map models;

[0049] Set up drones, which deliver tobacco from tobacco storage warehouses to tobacco receiving and delivery points according to the delivery routes.

[0050] The tobacco storage warehouse is used to store tobacco. When dividing the tobacco distribution area, the tobacco storage warehouse and the tobacco receiving and distribution point are included in the tobacco distribution area, and the surrounding areas around the tobacco storage warehouse and the tobacco receiving and distribution point that can be used for delivery by drones are divided into the tobacco distribution area.

[0051] The terrain information of the tobacco distribution area is obtained through the Beidou communication system, including the altitude, slope, terrain undulations, etc. of the tobacco distribution area. At the same time, meteorological information is obtained, including wind speed, wind direction, rainfall, temperature, etc. The terrain information is used to establish a three-dimensional map model; the meteorological information includes real-time meteorological information and weather forecasts. The meteorological information is obtained before the transportation of tobacco orders as an auxiliary means of planning the distribution route.

[0052] The tobacco delivery order includes the type and quantity of the tobacco to be transported and the time of receipt.

[0053] A cloud server is set up to store and process weather information, terrain information, and tobacco delivery order information. When a tobacco delivery order is received, the order is obtained, and a reasonable delivery route is planned for the drone considering the specific requirements of the tobacco delivery order and the geographical, meteorological, and other information provided by the three-dimensional map model.

[0054] Example 2

[0055] This embodiment differs from Embodiment 1 in that the tobacco storage warehouse includes a tobacco transfer warehouse and a tobacco distribution warehouse; one tobacco transfer warehouse and several tobacco distribution warehouses are arranged in the tobacco distribution area; the tobacco transfer warehouse is arranged at a main transportation road, and the tobacco distribution warehouse is arranged between the tobacco transfer warehouse and the tobacco distribution receiving point.

[0056] The setting of tobacco storage warehouses has been optimized. Specifically, tobacco storage warehouses are divided into tobacco transfer warehouses and tobacco distribution warehouses. One tobacco transfer warehouse is set up inside the tobacco distribution area, and several tobacco distribution warehouses are arranged according to actual needs. Among them, the tobacco transfer warehouse is set up near the main road of transportation to facilitate the large-scale transfer of goods; and the tobacco distribution warehouse is reasonably distributed between the tobacco transfer warehouse and the tobacco distribution receiving point, thus forming an efficient distribution network, shortening the distribution distance and improving the distribution efficiency.

[0057] Example 3

[0058] This embodiment is different from Embodiment 2 in that the three-dimensional map model is established according to the Beidou grid code, terrain information, and meteorological information, including the following steps:

[0059] The acquired Beidou grid code, terrain information and meteorological information are subjected to in-depth data analysis and integration. Then, the terrain information is presented in a three-dimensional form using 3D map modeling software (such as ArcGIS, CityEngine, Blender, etc.), including landform features such as mountains, hills, and plains. At the same time, meteorological information, such as cloud distribution, wind and rain conditions, is dynamically integrated into the model. In the modeling process, attention is paid to the depiction of details and the guarantee of accuracy, so that the 3D map model can not only accurately reflect the actual geographical environment, but also display the possible impact of meteorological changes on the delivery route in real time, making it convenient for staff to query the delivery information.

[0060] Example 4

[0061] This embodiment is different from Embodiment 3 in that the method of planning a delivery route according to the tobacco delivery order and the three-dimensional map model includes the following steps:

[0062] Obtain the Beidou grid code corresponding to the location of the tobacco delivery receiving point and the tobacco storage warehouse that need to be delivered in the tobacco delivery order in the three-dimensional map model, set the tobacco delivery receiving point as the end point, and set the tobacco storage warehouse as the starting point;

[0063] Obtain the Beidou grid code for the area between the tobacco distribution receiving point and the tobacco storage warehouse;

[0064] Obtain terrain information of the area between the tobacco distribution receiving point and the tobacco storage warehouse on the three-dimensional model based on the Beidou grid code;

[0065] According to the terrain information on the 3D model, a route is planned for the drone to travel from the starting point to the end point;

[0066] The weather information of the area where the route is located is obtained according to the Beidou grid code, the route is reset based on the weather information, and a delivery route is generated.

[0067] In the process of tobacco distribution, it is first necessary to obtain the Beidou grid code corresponding to the location of the tobacco distribution receiving point and tobacco storage warehouse in the three-dimensional map model in the tobacco distribution order, and convert these coordinates into the corresponding Beidou grid code according to the coding rules of the Beidou grid code. The advantage of this is that complex geographic location information can be converted into a concise and unified coding form, which is convenient for subsequent data processing and analysis. By setting the tobacco distribution receiving point as the end point and the tobacco storage warehouse as the starting point, the direction and target of the distribution can be clarified. Through geographic information system (GIS) technology and Beidou positioning equipment, the coordinate positions of the tobacco distribution receiving point and the tobacco storage warehouse in the three-dimensional map model are determined.

[0068] To plan the tobacco distribution route, it is necessary to obtain the Beidou grid code of the area between the two locations. The grid code of the middle area can be deduced based on the Beidou grid codes of the known starting and ending points through the spatial interpolation algorithm. By obtaining the Beidou grid code of the middle area, various relevant information of the area in the three-dimensional map model can be further obtained to provide more comprehensive data support for the planning of the distribution route.

[0069] For example, if there are terrain obstacles such as mountains and canyons in the delivery area, the drone needs to avoid these areas when planning the route and choose a safer and more efficient flight path. At the same time, terrain information can also help determine the flight altitude and speed of the drone to ensure flight safety under different terrain conditions. In addition, multiple backup routes can be planned for the drone based on actual conditions to deal with emergencies and accidents.

[0070] At the same time, the real-time meteorological information and weather forecast of the area where the route is located are obtained according to the Beidou grid code, and the meteorological information is used as an auxiliary judgment condition to reset the route and generate a delivery route.

[0071] For example, if there is a strong wind area on the route, you can choose to lower the flight altitude or change the flight direction to reduce the impact of wind resistance on the drone. If there is precipitation, you can consider delaying the delivery time or choosing an alternative route to prevent the drone from being damaged by rain. By resetting the route in combination with weather information, a safer and more efficient delivery route can be generated. At the same time, the real-time weather monitoring system can also be used to dynamically track and adjust weather changes during the delivery process to ensure that the drone is always flying in a safe environment.

[0072] Example 5

[0073] The difference between this embodiment and embodiment 4 is that the acquired terrain information and meteorological information are stored separately, including the following steps:

[0074] Establishing a terrain information storage module and a meteorological information storage module, storing terrain information in the terrain information storage module, and storing meteorological information in the meteorological information module;

[0075] The Beidou grid is hierarchically divided, and the terrain information stored in the terrain information storage module is indexed with the Beidou grid codes of different levels; the meteorological information stored in the meteorological information storage module is indexed with the Beidou grid codes of different levels. By setting up a cloud server for data storage, a terrain information storage module and a meteorological information storage module for tobacco transportation are set up during the cloud service period. The acquired terrain information is stored in the terrain information storage module. The terrain information may include a variety of data such as the height, slope, and geomorphic features of the terrain. This information can be obtained through satellite remote sensing, terrain measurement and other technical means. At the same time, the meteorological information is stored in the meteorological information module. Meteorological information covers data in multiple aspects such as temperature, humidity, air pressure, wind direction, and wind speed. This information can be obtained through channels such as meteorological observation stations and meteorological satellites.

[0076] By indexing the terrain information stored in the terrain information storage module with Beidou grid codes at different levels, it is possible to quickly locate and query the terrain information of a specific area. When you need to query the terrain information of a certain area, you can quickly find the corresponding terrain data through the Beidou grid code to improve the query efficiency. At the same time, the meteorological information stored in the meteorological information storage module is indexed with Beidou grid codes at different levels. This allows you to quickly locate the meteorological data of a specific area according to the Beidou grid code when querying meteorological information. Whether you are querying the current meteorological conditions or historical meteorological data, you can quickly obtain the required information through the index.

[0077] For example, when planning a UAV flight, you can use the terrain information and weather information index to quickly obtain the terrain and weather conditions on the flight route. If the flight route passes through a mountainous area, the terrain information index can be used to understand the terrain height and slope of the area so that the UAV can adjust the flight altitude and speed. At the same time, the weather information index can be used to obtain weather data such as wind direction and wind speed in the area, providing more accurate weather forecasts and risk assessments for UAV flights. Example 6

[0078] This embodiment is different from Embodiment 5 in that the provision of a drone, which delivers tobacco from a tobacco storage warehouse to a tobacco receiving and delivery point according to a delivery route, includes the following steps:

[0079] Get the starting and ending points of the delivery route and the cargo transportation volume of the tobacco delivery order;

[0080] Set up drones for transportation according to the amount of cargo to be transported;

[0081] The drone travels from the starting point of the delivery route to the end point of the delivery route to complete the transportation of tobacco.

[0082] Cargo transport volume includes the quantity, type, packaging specifications, weight and volume of tobacco. Different types of tobacco may have different packaging sizes and weights.

[0083] According to the obtained cargo transportation volume, if the cargo transportation volume is small, such as only a few boxes of a specific brand of tobacco, then small drones can be selected for transportation. Small drones are usually flexible and convenient, can take off and land in a relatively narrow space, and have relatively low energy consumption. They can quickly complete short-distance delivery tasks and are suitable for urgent orders or delivery needs with high timeliness requirements.

[0084] When the amount of cargo transported is large, it is necessary to consider using medium or large drones. These drones have greater load capacity and range, and can transport more tobacco cargo at one time. However, medium and large drones are relatively complex to operate and manage, requiring more spacious take-off and landing sites and more stringent flight safety measures.

[0085] When setting up the drone, you also need to consider how the goods are packaged and fixed. For fragile goods such as tobacco, you must choose appropriate packaging materials and fixings to ensure that they will not be affected by vibration, collision or other factors during flight. For example, you can use shockproof and moisture-proof packaging materials, and use professional fixing belts or shelves to ensure the stability of the goods. At the same time, you also need to reasonably adjust the center of gravity and balance of the drone according to the weight and volume of the goods to ensure the stability and safety of the flight.
