Description

Technical Field

[0001] The present invention belongs to the field of communication technology, and in particular relates to a flexible charging method, platform and system based on a communication base station. Background Art

[0002] As modern green transportation tools, new energy vehicles, cargo three-wheeled electric vehicles and passenger two-wheeled electric vehicles have demonstrated significant environmental protection advantages. However, charging issues are still an important hidden danger for users. The endurance of electric vehicles is not endless, and it is usually necessary to increase the capacity of the battery to improve the endurance.

[0003] In order to cope with the charging problem, some solutions have gradually emerged in the industry. Small charging stations near residential areas have obvious advantages in convenience and can provide users with close-range charging services. This makes it easier for users to charge in their daily lives. However, the construction of small charging stations still faces many challenges. Due to the limitations of power capacity, the difficulty of laying cables and the problem of land occupation, the construction application of such charging stations is often more complicated and can usually only serve three-wheeled electric vehicles and two-wheeled electric vehicles.

[0004] In comparison, large centralized charging stations can provide users with better services due to their complete functions, standardized management and higher safety. However, such charging stations often occupy a large area and are far away from users, resulting in a relative lack of convenience.

[0005] Therefore, the charging methods in the prior art cannot fully meet the needs, and users still need to spend a lot of time and energy when charging. Summary of the invention

[0065] By integrating the existing communication infrastructure, the present invention not only reduces the capital and operating costs of new charging facilities, achieves comprehensive coverage and market-oriented selection, but also effectively solves the difficulties of residents in nearby and emergency charging, and improves the overall charging economy and convenience. The specific beneficial effects are as follows:

[0066] 1. Resource integration

[0067] The present invention combines the electric vehicle charging function with existing communication base stations (such as mobile phone signal towers, wireless network base stations, etc.). Since these communication base stations are already widely distributed in cities and traffic-heavy areas, after integration, there is no need to reinvest a lot of resources in building new charging piles, reducing the demand for new infrastructure.

[0068] Resource integration also includes the following advantages:

[0069] 1.1 The construction of communication base stations is dense and covers a wide range, which enables them to provide charging services in every corner of cities and villages, significantly improving the convenience of charging. In addition, many base stations are located near public places, commercial areas and transportation hubs, so users can charge conveniently at any time, reducing the trouble of finding charging stations.

[0070] 1.2 The communication base station itself already has power supply facilities. The present invention can integrate charging equipment to effectively reduce the repeated investment in infrastructure construction. At the same time, by sharing communication equipment and charging facilities, it optimizes the use of land and resources, improves space utilization, and thus reduces the impact on the environment.

[0071] 1.3 Communication base stations can be equipped with high-power charging equipment. The present invention can provide faster charging speeds and significantly shorten the user's waiting time. At the same time, the intelligent dispatching system combined with the communication network can effectively optimize power distribution, reduce the pressure during peak charging periods, and improve overall charging efficiency.

[0072] 1.4 With the help of the network technology of the communication base station, the present invention can realize the real-time monitoring of the charging status and the analysis of user behavior, thereby improving the management efficiency of the charging facilities. At the same time, users can also obtain real-time charging information, including charging location, cost and remaining time, etc. through mobile phone applications, thereby significantly improving the user experience.

[0073] 2. Cost reduction

[0074] By utilizing existing infrastructure, the present invention significantly reduces the capital investment and operating costs. This means that operators and charging service providers can build charging networks at a lower cost, making the overall construction of electric vehicle charging piles more feasible. At the same time, this cost reduction can also be converted into lower charging fees for users, increasing the economic attractiveness of electric vehicles.

[0075] 3. Comprehensive coverage

[0076] The present invention can achieve comprehensive coverage of charging facilities, especially in densely populated urban areas. The geographical distribution of communication base stations already covers many residential areas, commercial centers and major transportation routes. Therefore, there is no need to go through a complicated site selection and construction process, and the charging network can be quickly expanded to ensure that users can easily find charging points in their daily lives.

[0077] 4. Improve economy and convenience

[0078] The present invention can not only improve the economic efficiency of electric vehicle charging by optimizing resource utilization, but also improve the user's charging experience through convenient charging options. As these advantages emerge, more and more people will tend to choose electric vehicles, thereby promoting the development of green travel and sustainable transportation.

[0094] Embodiment 1:

[0095] like Figure 1 As shown, this embodiment provides a flexible charging method based on a communication base station, the method is applied to a flexible charging platform based on a communication base station, and the method includes the following steps:

[0096] Step S1: Obtain the flexible surplus energy capacity of communication base stations within a preset range; and obtain the charging demand of electric vehicles.

[0097] Acquiring the flexible surplus energy capacity of communication base stations within a preset range is reflected in the fact that through intelligent scheduling and dynamic load management, the base station can adjust the use and distribution of energy in real time according to the season, flexibly respond to changes in supply and demand, and achieve efficient and stable operation. This flexibility ensures that the system can maximize the use of available resources and improve overall energy efficiency under different environments and demand conditions. The flexible matching of the charging demand of electric vehicles with the surplus energy capacity of communication base stations is reflected in real-time monitoring and intelligent scheduling. The system dynamically adjusts the charging plan and priority by collecting the charging status and demand forecast of electric vehicles, as well as the available surplus energy data of the base station, to ensure that the charging process is efficient and safe during peak charging demand periods. At the same time, the charging rate and time are flexibly adjusted according to real-time data, energy use is optimized, and the renewable energy of the base station is used as much as possible, thereby achieving a charging strategy that balances supply and demand, reduces costs, and maximizes resource utilization.

[0098] Specifically, obtaining the flexible surplus energy capacity of a communication base station within a preset range specifically includes the following steps:

[0099] Obtaining the maximum power supply capacity of the communication base stations within the preset range; and obtaining the current power consumption of the communication base stations within the preset range;

[0100] Wherein, the current power consumption of the communication base station varies according to the season;

[0101] Calculating the surplus energy capacity of all communication base stations within a preset range according to the maximum power supply capacity of the communication base station and the current power consumption of the communication base station;

[0102] The calculation formula of the surplus energy capacity of the communication base station is as follows:

[0103] P available =P capacity -P current ;

[0104] Where P available represents the surplus energy capacity of the communication base station, P capacity Indicates the maximum power supply capacity of the communication base station, P current Indicates the current power consumption of the communication base station.

[0105] The implementation steps for obtaining the charging requirements of electric vehicles can be divided into the following main links:

[0106] 1. User registration and information collection

[0107] User registration: Develop a mobile app or online platform to allow users to register and create personal accounts.

[0108] Information filling: During the registration process, basic user information is collected, such as vehicle type, brand, charging requirements (such as battery type, capacity, frequency), common charging locations, and preferred charging time.

[0109] 2. Real-time monitoring and data collection

[0110] Vehicle system connection: Connect to the electric vehicle's OBD (on-board diagnostic system) or other smart devices to obtain real-time information such as the vehicle's battery power, charging status, and mileage.

[0111] Information transmission: Real-time data is transmitted to the intelligent management platform via the mobile network to ensure that the platform can obtain the latest charging demand information at any time.

[0112] 3. User behavior analysis

[0113] Data analysis: Use data analysis tools to analyze users’ charging behavior, including charging time, charging frequency, and charging location.

[0114] Pattern recognition: Identify users’ charging patterns and preferences through historical data mining, providing a basis for subsequent demand forecasting.

[0115] 4. Demand Forecasting

[0116] Machine learning algorithm: Apply machine learning algorithm to predict the user's future charging needs based on the collected user behavior data. For example, if the user frequently charges at 10 pm on weekdays, the system can automatically identify this behavior.

[0117] Geographic location analysis: Use geographic information systems (GIS) to analyze users’ geographic locations and combine data from surrounding charging facilities to predict users’ charging needs at different locations.

[0118] 5. User feedback and adjustments

[0119] User interaction: Notifications and questionnaires are sent to users through the APP to obtain user feedback on charging services and needs in order to adjust service strategies.

[0120] Adjust services: Update charging service plans based on user feedback and the latest data analysis results to ensure that they meet changing user needs.

[0121] 6. Provide personalized recommendations

[0122] Recommendation system: Based on the user's needs and preferences, it recommends appropriate charging facilities and times to the user, such as recommending to use the nearest charging station when the battery is low, or charging during the off-peak hours at night to save costs.

[0123] Optimize charging solutions: In combination with local electricity price policies, the intelligent management platform provides the most optimized charging solutions based on user needs, encouraging users to choose the charging strategy that best suits them.

[0124] Step S2: flexibly matching the charging demand of the electric vehicle with the surplus energy capacity of the communication base station to obtain a charging strategy.

[0125] Specifically, the flexible matching of the charging demand of the electric vehicle and the surplus energy capacity of the communication base station to obtain a charging strategy specifically includes the following steps:

[0126] According to the charging priority of each electric vehicle, the charging requirements of the electric vehicles are sorted; and a list of electric vehicles is obtained;

[0127] According to the electric vehicle list, the charging demand of the electric vehicle is matched with the surplus energy capacity of the communication base station, that is, the charging strategy is obtained;

[0128] Among them, if the charging demand of the i-th electric vehicle can be met by the surplus energy capacity of the j-th communication base station, the i-th electric vehicle will be allocated to the j-th communication base station, and the surplus energy capacity of the j-th communication base station will be updated; if the charging demand of the k-th electric vehicle cannot be met by the surplus energy capacity of any communication base station, the words "unable to charge" will be displayed on the display screen, and the k-th electric vehicle will be deleted from the electric vehicle list;

[0129] Among them, the number of all electric vehicles with charging needs is m1, and the number of communication base stations with surplus energy capacity is m2; i∈m1, k∈m1, j∈m2, m1 and m2 are both natural numbers greater than or equal to 1;

[0130] The updating formula of the surplus energy capacity of the j-th communication base station is as follows:

[0131] P available-j =P capacity-j -P current-j -P i ;

[0132] Where P available-j represents the surplus energy capacity of the jth communication base station, P capacity-j represents the maximum power supply capacity of the jth communication base station, P current-j represents the current power consumption of the jth communication base station; P i represents the charging capacity of the i-th electric vehicle.

[0133] Step S3: When the electric vehicle is connected to the communication base station for charging, the charging of the electric vehicle is controlled based on the charging strategy.

[0134] When an electric vehicle is connected to a communication base station for charging, this embodiment can implement charging control based on an intelligent charging strategy. Specific measures include:

[0135] 1. Charging priority management

[0136] Different charging priorities can be set based on vehicle power, user reservations or charging needs, so that vehicles that need charging the most can be connected first.

[0137] 2. Dynamic power regulation

[0138] According to the real-time grid load and charging peak conditions, the charging power of each vehicle is intelligently adjusted to ensure that the grid carrying capacity is not exceeded, while ensuring that the user's charging needs are met.

[0139] 3. Optimize charging time

[0140] Taking into account users' car usage needs and charging costs, a charging schedule is formulated to encourage users to choose charging during periods of low electricity prices, thereby reducing charging costs.

[0141] 4. Status monitoring and feedback

[0142] Continuously monitor parameters such as current, voltage and temperature during the charging process to ensure safe charging, and provide timely feedback to users when abnormal situations occur.

[0143] 5. Data Analysis and Learning

[0144] Collect charging data, analyze user charging behaviors and preferences, continuously optimize charging strategies, and improve the intelligence level of the charging management system.

[0145] 6. User Interaction and Notification

[0146] Push information such as charging status, estimated completion time and cost to users through mobile applications to enhance user participation and experience.

[0147] 7. Multiple charging modes supported

[0148] Provide multiple charging modes, such as fast charging, slow charging, etc., to meet the needs of different users and flexibly allocate resources.

[0149] Step S4: Calculate the charging cost.

[0150] Specifically, the charging cost is calculated, including:

[0151] Collect charging data of electric vehicles;

[0152] Based on the preset rate plan, the charging cost is calculated according to the charging data of the electric vehicle.

[0153] As a specific implementation method, the charging fee is calculated based on the preset rate scheme according to the charging data of the electric vehicle, and specifically includes the following steps:

[0154] Pre-set different charging rates according to different time periods and different user types;

[0155] The charging data includes charging start time, end time, charging power and power consumed;

[0156] The consumed electricity is segmented by time period and user type, and combined with the charging power, the cost of each segment is calculated and summarized to obtain the charging cost.

[0157] Step S5: After the electric vehicle is charged, the charging fee is displayed on the display screen for the user to pay, thereby completing the flexible charging based on the communication base station.

[0158] The principle framework of this embodiment is as follows Figure 3 As shown in the figure, the primary task of the power supply of the communication base station is to ensure the communication network service. Therefore, the charging service configured by the communication base station is to provide charging services for surrounding electric vehicle users based on the surplus capacity of the communication base station and the specially designed algorithm logic, while ensuring the safe power supply of the communication base station and making the best use of the resources of the communication base station.

[0159] This embodiment makes full use of the existing idle resources of the communication base station, which can solve the dilemma of residents' nearby and emergency charging. It realizes comprehensive coverage and market-oriented selection of flexible intelligent charging. The so-called "flexibility" refers to the power supply of the communication base station, which is primarily used to ensure the service of the communication network. Therefore, the charging facilities of the present invention are based on the premise of giving priority to ensuring communication security, according to the abundant capacity of the communication base station (this varies according to the communication business, environmental conditions, etc.), according to a specially designed algorithm, and on the premise of ensuring safety, to maximize the use of the resources of the communication base station to provide charging services for surrounding electric vehicle users. The so-called "intelligence" means that it can perform intelligent accounting according to the occupation of resources, distance, and operating costs, etc., according to a specially designed algorithm, and publish transparent service information such as the type of rechargeable vehicles, estimated charging time, and charging electricity price through the management platform for users to choose. It can also guarantee the profits of the operating unit and achieve sustainable operation.

[0160] The entire "flexible charging" system consists of two parts: hardware and software. In the hardware part, the system includes power modules, power control management, charging interfaces and flexible charging controllers. Among them, the power module is responsible for converting AC mains power (380 / 220V) into DC power through AC / DC, and cooperates with PWM technology to achieve high-precision voltage and current output control. As the CPU of the power module in the system, the power control management accurately manages the power output. The charging interface, commonly known as the charging gun, provides different modes of interfaces according to the vehicle type and charging requirements, such as DC or AC, fast charging or slow charging, etc. The flexible charging controller is the main control unit of the system. It is responsible for integrating information and real-time data from the management platform, and using optimization algorithms to coordinate the charging process to achieve optimal resource allocation and maximize economic benefits, while ensuring the safe operation of the system.

[0161] The software part, namely the flexible intelligent charging management platform, is the brain of the system. The platform collects users' charging needs through the Internet or APP, including vehicle type, charging method, location and other personalized needs. Combined with the power supply capacity collected by the hardware and the power demand of the communication base station, the algorithm matches the user with the best charging plan: the charging method of the vehicle, the best electricity price option (such as ordinary electricity price, preferential electricity price or peak electricity price) and the most convenient charging station location. In addition, the platform also conducts data statistics and user behavior analysis of the charging business, and is responsible for the calculation and deduction of charging fees, while managing all charging resources.

[0162] Figure 4 Shown is a schematic diagram of electric vehicle charging based on a communication base station; Figure 5 The figure shows a schematic diagram of charging an electric two-wheeled vehicle based on a communication base station. Both electric vehicle charging and electric two-wheeled vehicle charging are flexible charging based on a communication base station.

[0163] Specific examples are as follows:

[0164] The power consumption capacity of a communication base station is 20kW, that is, reference information 3 is set to 20kW.

[0165] In a certain summer, the system collects in real time that the current communication business power consumption of the base station (including the power consumption of necessary supporting equipment such as air conditioners, etc.) is 16.5 kW, that is, the input signal 1 is set to 16.5 kW.

[0166] After logical calculation, the charging capacity that the communication base station can currently provide is 20-16.5=3.5kW.

[0167] When the "Flexible Intelligent Charging Management Platform" pushes a user's charging demand, the electric car requires 7kW. After analysis, the charging capacity here does not meet the requirements. The demand is returned to the platform as "unsatisfactory" and matched by the platform with other sites.

[0168] When the "Flexible Intelligent Charging Management Platform" pushes a user's charging demand, which requires 0.2kW for a two-wheeled electric vehicle, after analysis, the charging capacity here fully meets the requirement, and the demand is returned to the platform as "satisfied", and the platform guides the user to arrive and complete the charging. And obviously, there is still enough charging capacity here, so multiple electric vehicles can be charged at the same time.

[0169] In winter, because the air conditioner of the base station is not turned on, the real-time communication load collected at this time is 12kW, and the charging capacity that the base station can currently provide is 20-12=8kW.

[0170] If at this time, when the "Flexible Intelligent Charging Management Platform" pushes a 7kW demand for an electric car, after analysis, the charging capacity here can meet the requirements, then the "satisfied" signal will be returned to the platform to guide the user to drive to the base station for charging.

[0171] While the vehicle is charging, the charging pile reports the charging power, duration and other information to the platform, and the platform completes the timekeeping and billing processes.

[0172] The flexible charging technology in this embodiment represents an innovative charging method that is fundamentally different from traditional charging systems. In traditional systems, charging current and voltage are usually fixed values, while flexible charging technology does not fix these parameters. Instead, it "negotiates" through the platform based on current demand and available charging capacity to achieve the optimal match between resources and demand. This technology is particularly suitable for situations where resources are limited or need to be shared. For example, during the charging process, if the power demand of the communication base station suddenly increases, resulting in a sharp increase in the total input current, the system based on flexible charging technology can quickly adjust the input current of the charging facility, reduce the charging intensity, and ensure the stability of the communication service while still ensuring the provision of services to charging users. In the event that such an adjustment results in an extension of the charging time, the system can resolve user dissatisfaction through appropriate compensation methods, thereby enhancing user satisfaction and loyalty.

[0173] In this embodiment, the flexible charging technology is equipped with various types of charging interfaces, which can widely adapt to the different charging needs of various vehicles. These charging interfaces, commonly referred to as charging guns, include DC and AC charging interfaces, and also provide options for high-power fast charging and low-power slow charging. Utilizing the existing resources of communication base stations, the main goal of this technology is to provide convenient charging services for users' home vehicles. Taking into account the diversity of household vehicles, such as two-wheeled electric vehicles, three-wheeled electric vehicles, and small four-wheeled electric trucks for families, these vehicles are of many types and have different needs. Therefore, this solution deliberately designs a variety of charging interfaces to meet a wide range of needs, and ensures that most of the market can be covered, providing users with a one-stop charging solution.

[0174] The intelligent management platform of this embodiment communicates with the user's APP in real time, and uses the Beidou system's geographic location information (GIS) to accurately track and update the user's location. When the user raises a charging demand and opens the APP, the system will automatically feed back information to the platform based on the vehicle's current location. The platform will match the nearest available charging point based on the vehicle's location information, and query key data such as the interface information and rechargeable capacity of each charging point to recommend the most suitable charging station to the user. Through the map guidance function, the platform also provides users with navigation routes to ensure that users can successfully reach the recommended charging location.

[0175] According to the current power supply policy, the electricity prices in different regions are not fixed. Every month, the electricity transaction price will be different, so the basic electricity price will also change accordingly. At the same time, the electricity price is also charged according to the peak and off-peak periods of electricity consumption. During the peak power consumption period (usually 6-8 hours a day), the power supply bureau charges users the peak electricity price; during the off-peak period such as midnight, the off-peak electricity price is used; and the normal electricity price is applied to other normal periods.

[0176] As the operator of the charging business, the communication operator needs to formulate corresponding charging service and electricity price strategies. In this implementation plan, the intelligent management platform can monitor the electricity price policy of the local power supply department in real time, and clarify the user's charging fee mechanism through financial analysis and operation strategy. The platform will provide users with the best charging plan based on this mechanism. For example, the platform will analyze the user's data, understand their habitual charging stations, charging time periods, and vehicle types, and conduct behavioral analysis. If the analysis results show that the user is an office worker and is sensitive to electricity prices, the system will be able to recommend charging plans during the low-peak hours at night and close to home to meet the user's demand for low-cost charging services.

[0177] This embodiment first obtains the flexible surplus energy capacity of the communication base station within a preset range; and obtains the charging demand of the electric vehicle; then flexibly matches the charging demand of the electric vehicle with the surplus energy capacity of the communication base station to obtain a charging strategy; then when the electric vehicle is connected to the communication base station for charging, the charging of the electric vehicle is controlled based on the charging strategy; the charging fee is calculated; and finally, after the charging of the electric vehicle is completed, the charging fee is displayed for the user to pay, so as to complete the flexible charging based on the communication base station. This embodiment can adjust the charging current at any time according to changes in communication services, environmental conditions, etc., which can not only ensure the power supply safety of the main business of the communication base station, but also flexibly integrate the existing communication infrastructure, achieve comprehensive coverage and market-oriented selection, and improve the overall charging economy and convenience.

[0195] The matching module comprises:

[0196] A determination submodule, used to determine whether the charging demand of the electric vehicle can be met by the surplus energy capacity of the communication base station;

[0197] A first processing submodule, connected to the determination submodule, for allocating the i-th electric vehicle to the j-th communication base station and updating the surplus energy capacity of the j-th communication base station when the determination submodule determines that the charging demand of the i-th electric vehicle can be met by the surplus energy capacity of the j-th communication base station;

[0206] The platform in this embodiment can execute the method in Embodiment 1.

[0207] Embodiment 3:

[0208] This embodiment provides a flexible charging management system, the system comprising:

[0209] A communication base station for providing charging power to electric vehicles;

[0210] A power control management device, connected to the communication base station, for monitoring and managing the output of the communication base station to ensure that the power output meets the requirements and safety standards of the electric vehicle;

[0211] The flexible charging platform based on the communication base station described in Example 2;

[0212] The flexible charging platform is connected to the power control management device to realize flexible charging of electric vehicles.

[0213] The core of flexible charging technology is the flexible charging controller (or controller for short). The controller is equivalent to an operational amplifier, which makes a comprehensive comparison and analysis of input signals, reference signals, etc., and finally accurately controls the power output of the charging facility to complete the charging service. The specific implementation process is as follows: Figure 2 As shown:

[0214] 1. Input signal 1 is the real-time collected information on the power consumption of the communication business of the communication base station. It is the main business of the communication base station, so the power consumption must be fully guaranteed.

[0215] In fact, the total AC input current value of the communication base station is generally collected during engineering implementation. Before the charging service is started, the total input of the base station is the electricity used for the communication business. During the charging process, the total input current will inevitably increase due to the increase in electricity used for the communication business. Since the power supply capacity of the base station is a fixed value, the upper limit of the input current of the charging facility needs to be lowered at this time, that is, the charging capacity needs to be reduced to achieve flexible charging and ensure the safety of power supply for the main communication business.

[0216] 2. Input signal 2 is the user's expected electric vehicle charging demand information provided by the supporting "flexible intelligent charging management platform".

[0217] Through interactive communication between the management platform and users through APP and other means, the platform can timely collect users' charging needs, including location information, charging model, charging power, and other user preferences. At the same time, the platform can match the location information of the charging pile (base station), the charging pile capacity, electricity price policy, etc. on the platform side with the user's algorithm. After reaching a consensus, the charging pile location information, interface information, etc. will be pushed to the user, so that the user can reach the nearest, fast or economical charging based on this.

[0218] 3. Reference signal 3 is the power supply capacity information of the communication base station.

[0219] The power consumption capacity reported to the local power supply department during the initial construction of a communication base station is the power supply capacity of the communication base station. The specific parameter is the output port capacity of the power supply department to the base station.

[0220] 4. Output signal 4, namely charging output and billing information, etc.

[0221] The output signal of the controller is an instruction sent to the power control management module of the charging facility. Combined with other user identification information, it ultimately outputs the charging current to the electric vehicle through the charging interface and feeds back billing information to the platform.

[0222] The flexible charging management system of this embodiment is also a flexible intelligent charging management platform. The so-called "intelligent" means that it can perform intelligent accounting based on the resource occupation, distance, and operating costs, etc., according to specially designed algorithms, and publish transparent service information such as rechargeable vehicle types, estimated charging time, and charging electricity prices through the management platform for users to choose. It can also ensure the profits of the operating unit and achieve sustainable operation.

[0223] (1) “Flexible Intelligent Charging Management Platform” is an auxiliary management system that is compatible with flexible charging piles. The system has functions such as resource management, information release, time and billing, and map guidance.

[0224] (2) Resource management: All flexible smart charging piles configured in a certain area and by a certain owner can be centrally managed, and the assets, services, costs, and benefits of the project can be uniformly managed;

[0225] (3) Information release: It has an intelligent algorithm that can push information such as the occupancy status, service capabilities, and charging costs of nearby charging piles to registered users for user selection;

[0226] (4) Time and billing: It can time and bill users’ charging behavior. It can timely track and implement local time-of-use electricity price policies, calculate charging costs and benefits, etc.

[0227] (5) Map guidance: Based on the Beidou system, it can accurately track the user's location information and demand information, and can achieve the shortest distance, lowest cost, and fastest time based on algorithms and optimal matching.
