Description

Technical Field

[0001] The present invention relates to the technical field of low-altitude economy, and particularly to an analysis method and system for the development form of low-altitude economy based on high-density cities. Background Art

[0002] With the acceleration of the urbanization process, high-density cities are facing problems such as traffic congestion and low logistics distribution efficiency. As a new economic development model, the low-altitude economy uses the low-altitude area to carry out various economic activities, providing a new way to solve these problems.

[0003] When traditional analysis methods and systems for the development form of low-altitude economy analyze the development form of low-altitude economy, they analyze the areas in need of low-altitude economic services according to the changes of traffic information, logistics information and scenic area information throughout the day. After obtaining this area, according to the information of this area, they analyze the demand scale of low-altitude economic services required by this area, and provide low-altitude economic services according to the demand scale of low-altitude economic services. Obviously, such analysis methods and systems for the development form of low-altitude economy have at least the following deficiencies: 1. Traditional analysis methods and systems for the development form of low-altitude economy analyze the areas in need of low-altitude economic services according to the changes of traffic information, logistics information and scenic area information throughout the day. When a sudden change occurs in a certain area, they cannot provide low-altitude economic services for this area in a timely manner, and cannot ensure that each area can obtain effective low-altitude economic services in a timely manner.

[0004] 2. Traditional analysis methods and systems for the development form of low-altitude economy provide low-altitude economic services according to the overall demand scale of low-altitude economic services in the service area, without refining the low-altitude economic services in the service area, and cannot ensure that each region of the city can obtain sufficient low-altitude economic services. Summary of the Invention

[0005] Aiming at the above existing technical deficiencies, the purpose of the present invention is to provide an analysis method and system for the development form of low-altitude economy based on high-density cities.

[0006] To solve the above technical problems, the present invention adopts the following technical solutions: In the first aspect, the present invention provides an analysis method for the development form of low-altitude economy based on high-density cities, including the following steps: Step 1. Regional division: Divide the city into each urban area according to a preset area threshold.

[0007] Step 2. Obtain the low-altitude economic service time period: Divide the whole day into each time period according to a preset time interval, obtain the population density and traffic information of each urban area in each time period, analyze the low-altitude economic service index of each urban area in each time period, and obtain each service time period of each urban area according to the analysis result.

[0008] Step 3. Obtain the low-altitude economic service fields: Obtain the information of each field in each city area during each service time period, calculate the traffic characteristic value, logistics characteristic value, and scenic area characteristic value of each city area during each time period, and obtain the service fields of low-altitude economy in each city area during each service time period according to the calculation results.

[0009] Step 4. Allocate low-altitude economic services: Obtain the information of each service field in each city area during each service time period, analyze the demand scale value of each service field in each city area during each service time period, analyze the priority coefficient of each service field in each city area during each service time period, and allocate low-altitude economic services to each service field in each city area during each service time period.

[0010] Preferably, the process of obtaining each service time period of each city area is as follows: Divide the whole day into each time period according to a preset time interval, obtain the population density and traffic information of each city area during each time period from the database, perform normalization processing and input it into the analysis model, and output the low-altitude economic service index of each city area during each time period. The low-altitude economic service index includes 0 and 1. If the low-altitude economic service index of a certain city area during a certain time period is 1, it means that the city area needs low-altitude economic services during this time period, and this time period is called the service time period. If the low-altitude economic service index of a certain city area during a certain time period is 0, it means that the city area does not need low-altitude economic services during this time period. Obtain each service time period of each city area in this way.

[0011] Preferably, the process of obtaining the service fields of low-altitude economy in each city area during each service time period is as follows: Obtain the traffic information, logistics information, and scenic area information of each city area during each service time period from the database, calculate the traffic field characteristic value, logistics field characteristic value, and scenic area field characteristic value of each city area during each service time period, and compare them with the traffic field standard characteristic value, logistics field standard characteristic value, and scenic area field standard characteristic value. Each field higher than its standard characteristic value is called each service field. Obtain the service fields of low-altitude economy in each city area during each service time period in this way.

[0012] Preferably, the process of calculating the characteristic value is as follows: Denote the traffic flow of each key road and the average vehicle speed on each key road in each service time period of each city area as and , where represents the number of each key road, represents the number of each city area, represents the number of each service time period, , and are all positive integers. According to and determine the traffic characteristic values of each urban area in each service time period .

[0013] Let the total population of each urban area, the number of delivery express items and the number of delivery staff of each logistics company in each service time period of each urban area be recorded as , and respectively, where represents the number of each logistics company, is a positive integer. According to , and determine the logistics characteristic values of each urban area in each service time period .

[0014] Let the area of each scenic spot in each urban area and the number of tourists in each service time period of each urban area be recorded as and respectively, where represents the number of each scenic spot, is a positive integer. According to and determine the scenic spot characteristic values of each urban area in each service time period .

[0015] Preferably, allocate low-altitude economic services to each service field in each service time period of each urban area. The specific process is as follows: S11. In each urban area, obtain the information of each service field in each service time period from the database, perform normalization processing and input it into the deep learning model to output the demand scale values of each service field in each service time period. Obtain the unit demand scale value cost of low-altitude economic services and the unit demand scale value service cost that each service field can pay from the database. According to the demand scale values of each service field in each service time period, the unit demand scale value cost of low-altitude economic services and the unit demand scale value service cost that each service field can pay, determine the priority coefficients of each service field in each service time period of each urban area.

[0016] S12. In each urban area, allocate low-altitude economic services to each service field in each service time period according to the priority coefficients of each service field in each service time period and the situation of each service field in each service time period.

[0017] Preferably, the low-altitude economy services are allocated to each service area in each service time period, and the specific process is as follows: within each urban area, the urban area is divided into each sub-area according to a preset division area threshold. At the same time, each service time period is numbered in chronological order, and the service time period numbered 1 is called the first-level time period, and the service time period numbered 2 is called the second-level time period. First, the low-altitude economy services are allocated to each service area in the first-level time period according to the situation and priority coefficient of each service area in the first-level time period. Then, according to the allocation results of the low-altitude economy services of each service area in the first-level service time period, the situation and priority coefficient of each service area in the second-level time period, the low-altitude economy services are allocated to each service area in the second-level time period. Finally, the service time period numbered 2 is called the first-level service time period, and the service time period numbered 3 is called the second-level service time period, and the low-altitude economy services are allocated to each service area in the service time period numbered 3 according to the above method until the allocation of the low-altitude economy services for each service area in each service time period is completed.

[0018] Preferably, the process of allocating the low-altitude economy services to each service area in the first-level time period is as follows: obtain the priority coefficients of each service area in the first-level time period, and number each service area in descending order, and call the service area numbered 1 the priority allocation area. Obtain the characteristic values of the priority allocation area in each sub-area and compare them with its standard characteristic values. Obtain each sub-area where the characteristic value of the priority allocation area is greater than its standard characteristic value, and call it each allocation sub-area. Determine the demand scale value of the priority allocation area in each allocation sub-area, and allocate the low-altitude economy services to each allocation sub-area according to it. After the allocation is completed, call the service area numbered 2 the priority allocation area, and allocate the low-altitude economy services to the service area numbered 2 in each sub-area according to the above method until the allocation of the low-altitude economy services for each service area in the first-level time period is completed.

[0019] Preferably, low-altitude economic services are allocated to each service area in the secondary time period, and the specific process is as follows: According to the method of numbering each service area in the primary time period, each service area in the secondary time period is numbered, and the service area numbered 1 is called the priority allocation area. Its respective allocation sub-areas are obtained, and the demand scale value of the priority allocation area in each allocation sub-area is determined. The priority allocation area in the secondary time period is compared with each service area in the primary time period. If the priority allocation area in the secondary time period is the same as a certain service area in the primary time period, it is called the marked area. The coordinates of each allocation sub-area of the marked area in the primary time period and its coordinates in the secondary time period are obtained and compared. The allocation sub-areas with the same coordinates are called each secondary allocation sub-area, and the allocation sub-areas with different coordinates are called each marked sub-area. For each secondary allocation sub-area, the low-altitude economic services of each secondary allocation sub-area are adjusted according to their demand scale values in the primary time period and the secondary time period. For each marked sub-area, low-altitude economic services are allocated to each marked sub-area according to its demand scale value in the secondary time period. If the priority allocation area in the secondary time period is not the same as any service area in the primary time period, low-altitude economic services are allocated to each allocation sub-area according to their demand scale values in each allocation sub-area. After the allocation is completed, the service area numbered 2 is called the priority allocation area, and low-altitude economic services are allocated to the service area numbered 2 in each sub-area according to the above method until the allocation of low-altitude economic services for each service area in the secondary time period is completed.

[0020] Preferably, the adjustment of the low-altitude economic services for each secondary allocation sub-area is as follows: S21. Obtain the demand scale values of each secondary allocation sub-area in the primary time period and the secondary time period, and compare them. The secondary allocation sub-areas with the same demand scale values in the primary time period and the secondary time period are called each unchanged sub-area. The secondary allocation time periods with the demand scale value in the primary time period less than the demand scale value in the secondary time period are called each increasing sub-area. The secondary allocation time periods with the demand scale value in the primary time period higher than the demand scale value in the secondary time period are called each shrinking sub-area.

[0021] S22. For each invariant region, the low-altitude economic services thereof are not adjusted during the secondary time period. For each increased sub-region and each reduced sub-region, the sum of the demand scale value differences of each increased sub-region and the sum of the demand scale value differences of each reduced sub-region are obtained and compared. If the sum of the demand scale value differences of each increased sub-region is less than the sum of the demand scale value differences of each reduced sub-region, the redundant low-altitude economic services of each reduced sub-region are randomly allocated to each increased sub-region during the secondary time period. If the sum of the demand scale value differences of each increased sub-region is greater than the sum of the demand scale value differences of each reduced sub-region, the difference between the sum of the demand scale value differences of each increased sub-region and the sum of the demand scale value differences of each reduced sub-region is calculated, and low-altitude economic services are increased according to the difference. During the secondary time period, the redundant low-altitude economic services of each reduced sub-region and the increased low-altitude economic services are randomly allocated to each increased sub-region.

[0022] In a second aspect, the present invention provides a low-altitude economic development form analysis system based on a high-density city, including the following modules: A regional division module is used to divide the city into each urban region according to a preset area threshold.

[0023] A low-altitude economic service time period acquisition module is used to divide the whole day into each time period according to a preset time interval, obtain the population density and traffic information of each urban region in each time period, analyze the low-altitude economic service indicators of each urban region in each time period, and obtain each service time period of each urban region according to the analysis result.

[0024] A low-altitude economic service field acquisition module is used to obtain the traffic information, logistics information and scenic area information of each urban region in each time period, calculate the traffic characteristic value, logistics characteristic value and scenic area characteristic value of each urban region in each time period, and obtain each service field of low-altitude economy in each service time period of each urban region according to the calculation result.

[0025] A low-altitude economic service allocation module is used to obtain the information of each field of each urban region in each service time period, calculate the traffic characteristic value, logistics characteristic value and scenic area characteristic value of each urban region in each time period, and obtain each service field of low-altitude economy in each service time period of each urban region according to the calculation result.

[0026] A database is used to store the population density of each urban region in each time period, the traffic flow of each key road, the average vehicle speed on each key road, the total population, the number of express deliveries distributed by each logistics company, the number of deliverymen of each logistics company, the area of each scenic area and the number of tourists in each scenic area.

[0027] The beneficial effects of the present invention are as follows: 1. The present invention provides an analysis method and system for the development form of low-altitude economy based on high-density cities. First, the city is divided into various urban areas, and the whole day is divided into various time periods. According to the population density and traffic information of each urban area in each time period, the service time periods of each urban area are obtained. Then, according to the traffic information, logistics information, and scenic area information of each urban area in each service time period, the service fields of each urban area in each service time period are obtained. Finally, the demand scale values and priority coefficients of the service fields of each urban area in each service time period are analyzed, and low-altitude economic services are allocated to the service fields of each urban area in each service time period, ensuring that each field can obtain effective low-altitude economic services in a timely manner and that each area of the city can obtain sufficient low-altitude economic services.

[0028] 2. The present invention divides the city into various urban areas according to a preset area threshold and divides the whole day into various time periods according to a preset time interval. The population density and traffic information of each urban area in each time period are obtained from the database, the service time periods of each urban area are analyzed, and the traffic field characteristic values, logistics field characteristic values, and scenic area field characteristic values of each service time period of each urban area are calculated. According to the calculation results, the service fields of low-altitude economy in each urban area in each service time period are obtained, ensuring that each field can obtain effective low-altitude economic services.

[0029] 3. In each urban area of the present invention, the information of the service fields in each service time period obtained from the database is used to determine the demand scale values of the service fields in each service time period. The low-altitude economic service cost and the service fees that each service field can pay are obtained from the database to determine the priority coefficients of the service fields of each urban area in each service time period. Then, each urban area is divided into various sub-areas, and the demand scale values of the allocated sub-areas of the service fields in each time period are obtained. At the same time, low-altitude economic services are allocated to the allocated sub-areas of the service fields of each urban area in each time period, ensuring that each area of each city can obtain sufficient low-altitude economic services.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0034] Please refer to Figure 1 As shown, the present invention provides an analysis method for the development form of low-altitude economy based on high-density cities, including the following steps: Step 1: Regional division: Divide the city into each urban area according to a preset area threshold.

[0035] It should be noted that the preset area threshold is a critical value used to evaluate whether the division of urban areas is reasonable and is set by the staff.

[0036] Step 2: Obtain the service time period of the low-altitude economy: Divide the whole day into each time period according to a preset time interval, obtain the population density and traffic information of each urban area in each time period, analyze the low-altitude economy service indicators of each urban area in each time period, and obtain the service time periods of each urban area according to the analysis results.

[0037] It should be noted that the traffic information includes vehicle flow, average vehicle speed of each road, and congestion duration of each road, etc.

[0038] In a specific embodiment, the specific process of obtaining the service time periods of each urban area is as follows: Divide the whole day into each time period according to a preset time interval, obtain the population density and traffic information of each urban area in each time period from the database, perform normalization processing and input it into the analysis model, and output the low-altitude economy service indicators of each urban area in each time period. The low-altitude economy service indicators include 0 and 1. If the low-altitude economy service indicator of a certain urban area in a certain time period is 1, it means that the urban area needs low-altitude economy service in this time period, and this time period is called the service time period. If the low-altitude economy service indicator of a certain urban area in a certain time period is 0, it means that the urban area does not need low-altitude economy service in this time period. In this way, the service time periods of each urban area are obtained.

[0039] It should be noted that connect this method and system with the traffic management system, logistics management system and scenic area management system, obtain traffic information, logistics information and scenic area information from them, and store them in the database.

[0040] It should also be noted that the analysis model: , where Represents the population density of the th urban area in the th time period, Represents the th urban area in the th time period for the th traffic information, Represents the th urban area in the th time period for the low-altitude economic service index, Represents the preset threshold of the low-altitude economic service coefficient, Represents the number of each urban area, = 1, 2, 3, ..., , Represents the total number of urban areas, Represents the number of each traffic information, = 1, 2, 3, ..., , Represents the total number of traffic information, Represents the number of each time period, = 1, 2, 3, ..., , Represents the total number of time periods, , , , , and are all positive integers.

[0041] Among them, the preset threshold of the low-altitude economic service coefficient is the critical value for judging whether low-altitude economic services are required in each time period, and it is set by the staff.

[0042] Step 3: Obtain the low-altitude economic service fields: Obtain the information of each field in each urban area during each service time period, calculate the traffic characteristic value, logistics characteristic value, and scenic area characteristic value of each urban area during each time period, and obtain each service field of low-altitude economy in each urban area during each service time period according to the calculation results.

[0043] It should be noted that the information of each field includes traffic information in the traffic field, logistics information in the logistics field, and scenic area information in the scenic area field. Traffic information includes the traffic flow of each key road and the average speed of vehicles on each key road, etc. Logistics information includes the number of express deliveries and the number of deliverymen of each logistics company, etc. Scenic area information includes the area of each scenic area and the number of tourists in each scenic area, etc.

[0044] In a specific embodiment, the process of obtaining each service field of the low-altitude economy in each service time period of each urban area is as follows: Obtain the traffic information, logistics information, and scenic area information of each service time period of each urban area from the database, calculate the traffic field characteristic value, logistics field characteristic value, and scenic area field characteristic value of each urban area in each service time period, and compare them with the traffic field standard characteristic value, logistics field standard characteristic value, and scenic area field standard characteristic value. Each field higher than its standard characteristic value is called each service field. In this way, each service field of the low-altitude economy in each service time period of each urban area is obtained.

[0045] It should be noted that the standard characteristic value of each field is a boundary value used to determine whether each field is a service field and is set by relevant staff.

[0046] In the above, the process of calculating the characteristic value is as follows: Denote the traffic flow of each key road and the average vehicle speed on each key road in each service time period of each urban area as and , where represents the number of each key road, represents the number of each urban area, represents the number of each service time period, , and are all positive integers. According to and , determine the traffic field characteristic value of each urban area in each service time period.

[0047] It should be noted that in it represents the total number of key roads, is a positive integer.

[0048] Denote the total population of each urban area, the number of delivery express items and the number of deliverymen of each logistics company in each service time period of each urban area as , and , where represents the number of each logistics company, is a positive integer. According to , and , determine the logistics field characteristic value of each urban area in each service time period.

[0049] It should be noted that , where , , Represents the total number of logistics companies.

[0050] The area of each scenic spot in each urban area and the number of tourists in each service time period of each urban area are respectively denoted as and , where represents the number of each scenic spot, is a positive integer. According to and , determine the scenic spot field characteristic value of each urban area in each service time period.

[0051] It should be noted that , where represents the total number of scenic spots.

[0052] Step 4: Low-altitude economic service allocation: Obtain the information of each service field in each urban area in each service time period, obtain the demand scale value of each service field in each urban area in each service time period, analyze the priority coefficient of each service field in each urban area in each service time period, and allocate low-altitude economic services to each service field in each urban area in each service time period.

[0053] In a specific embodiment, the process of allocating low-altitude economic services to each service field in each urban area in each service time period is as follows: S11. In each urban area, obtain the information of each service field in each service time period from the database, perform normalization processing and input it into the deep learning model, output the demand scale value of each service field in each service time period, obtain the unit demand scale value cost of low-altitude economic services and the unit demand scale value service cost that each service field can pay from the database, and determine the priority coefficient of each service field in each urban area in each service time period according to the demand scale value of each service field in each service time period, the unit demand scale value cost of low-altitude economic services, and the unit demand scale value service cost that each service field can pay.

[0054] It should be noted that the deep learning model learns the relationship between the information of each field and the corresponding low-altitude economic service scale value according to the marked information of each field. After learning, the information of each service field in each service time period is input into the deep learning model, and the demand scale value of each service field in each service time period is output.

[0055] It should also be noted that , where represents the priority coefficient of the th service field in the th service time period of the th urban area, represents the The service fee for the unit demand scale value that each service area can pay Represents the cost of the unit demand scale value of low-altitude economic services Represents the th city area's th service time period's th service area's demand scale value Represents the number of each service area = 1, 2, 3, When it is 1, it represents the transportation field When it is 2, it represents the logistics field When it is 3, it represents the scenic area field

[0056] S12. Within each city area, according to the priority coefficients of each service area in each service time period and the situations of each service area in each service time period, allocate low-altitude economic services to each service area in each service time period

[0057] In the above, the process of allocating low-altitude economic services to each service area in each service time period is as follows: Within each city area, divide the city area into each sub-area according to the preset division area threshold. At the same time, number each service time period in chronological order, and call the service time period numbered 1 the first-level time period, and call the service time period numbered 2 the second-level time period. First, allocate low-altitude economic services to each service area in the first-level time period according to the situations and priority coefficients of each service area in the first-level time period. Then, according to the allocation results of low-altitude economic services of each service area in the first-level service time period, the situations and priority coefficients of each service area in the second-level time period, allocate low-altitude economic services to each service area in the second-level time period. Finally, call the service time period numbered 2 the first-level service time period, call the service time period numbered 3 the second-level service time period, and allocate low-altitude economic services to each service area in the service time period numbered 3 according to the above method until the allocation of low-altitude economic services to each service area in each service time period is completed

[0058] It should be noted that the preset division area threshold is a critical value used to evaluate whether the division of sub-areas is reasonable, which is set by the staff. If the area of the sub-area is not equal to the preset division area threshold, it means that the division of the sub-area is unreasonable. If the area of the sub-area is equal to the preset division area threshold, it means that the division of the sub-area is reasonable

[0059] Among the above, the low-altitude economic services are allocated to each service area of the first-level time period, and the specific process is as follows: Obtain the priority coefficients of each service area of the first-level time period, number each service area in descending order, and call the service area numbered 1 the priority allocation area. Obtain the characteristic values of the priority allocation area in each sub-region, compare them with their standard characteristic values, obtain each sub-region where the characteristic value of the priority allocation area is greater than its standard characteristic value, and call them each allocation sub-region. Determine the demand scale values of the priority allocation area in each allocation sub-region, and allocate low-altitude economic services to each allocation sub-region according to them. After the allocation is completed, call the service area numbered 2 the priority allocation area, and allocate low-altitude economic services to the service area numbered 2 in each sub-region according to the above method until the allocation of low-altitude economic services for each service area of the first-level time period is completed.

[0060] It should be noted that one unit of demand scale represents one low-altitude economic service. Assuming that the demand scale value of a certain allocation sub-region is 2, it means that two low-altitude economic services need to be allocated to this sub-region.

[0061] Among the above, the low-altitude economic services are allocated to each service area of the second-level time period, and the specific process is as follows: Number each service area of the second-level time period according to the method of numbering each service area of the first-level time period, and call the service area numbered 1 the priority allocation area, and obtain each of its allocation sub-regions. At the same time, determine the demand scale values of the priority allocation area in each allocation sub-region. Compare the priority allocation area of the second-level time period with each service area of the first-level time period. If the priority allocation area of the second-level time period is the same as a certain service area in the first-level time period, call it the marked area. Obtain the coordinates of each allocation sub-region of the marked area in the first-level time period and the coordinates of each allocation sub-region of it in the second-level time period, and compare them. Call each allocation sub-region with the same coordinates each secondary allocation sub-region, and call each allocation sub-region with different coordinates each marked sub-region. For each secondary allocation sub-region, adjust the low-altitude economic services of each secondary allocation sub-region according to its demand scale values in the first-level time period and the second-level time period. For each marked sub-region, allocate low-altitude economic services to each marked sub-region according to its demand scale value in the second-level time period. If the priority allocation area of the second-level time period is not the same as each service area in the first-level time period, allocate low-altitude economic services to each allocation sub-region according to its demand scale value in each allocation sub-region. After the allocation is completed, call the service area numbered 2 the priority allocation area after the allocation is completed, and allocate low-altitude economic services to the service area numbered 2 in each sub-region according to the above method until the allocation of low-altitude economic services for each service area of the second-level time period is completed.

[0062] Among the above, the adjustment of the low-altitude economic services for each secondary distribution sub-region is as follows: S21. Obtain the demand scale values of each secondary distribution sub-region in the first-level time period and the second-level time period, and compare them. Those secondary distribution sub-regions with the same demand scale values in the first-level time period and the second-level time period are called invariant sub-regions. Those secondary distribution time periods with demand scale values in the first-level time period less than those in the second-level time period are called increasing sub-regions. Those secondary distribution time periods with demand scale values in the first-level time period higher than those in the second-level time period are called shrinking sub-regions.

[0063] S22. For each invariant region, do not adjust its low-altitude economic services in the second-level time period. For each increasing sub-region and each shrinking sub-region, obtain the sum of the demand scale value differences of each increasing sub-region and the sum of the demand scale value differences of each shrinking sub-region, and compare them. If the sum of the demand scale value differences of each increasing sub-region is less than the sum of the demand scale value differences of each shrinking sub-region, then randomly allocate the excess low-altitude economic services of each shrinking sub-region to each increasing sub-region in the second-level time period.
