Description

Technical Field

[0001] The present invention relates to the technical field of parking fee collection, and in particular to a regional time-based fee collection method and system for smart parking lots. Background Art

[0002] With the development of urbanization, the demand for parking space by car owners is increasing, parking resources are tight, and the management of open parking lots is becoming more and more complicated. At present, the parking fee collection method for different parking areas in open parking lots is usually a fixed fee collection strategy based on the parking time. For example, the fixed fee standard for each parking space in a certain parking area is 5 yuan / hour. However, in actual situations, the parking demand in different parking areas varies. Most car owners are accustomed to parking their cars in parking areas close to the entrances and exits with lower fees, which makes the parking areas deep in the parking lot have more vacant parking spaces, resulting in two extreme situations: a serious shortage of parking spaces and excessive waste of parking spaces in the parking area of ​​the parking lot. At the same time, it is easy to cause vehicle congestion during periods of heavy traffic, which is not conducive to the reasonable management of the parking lot. Summary of the invention

[0003] In order to solve the technical problem that the parking space charging standards in the current parking areas of the parking lot are fixed, resulting in an extreme imbalance in the use of parking spaces in different parking areas in the parking lot, which affects the reasonable management of the parking lot, the purpose of the present invention is to provide a regional time-based charging method and system for smart parking lots. The technical solutions adopted are as follows:

[0004] In a first aspect, an embodiment of the present invention provides a regional time-based charging method for a smart parking lot, the method comprising the following steps:

[0005] According to the parking situation of each parking space in each parking area in the smart parking lot within a preset time period, as well as the size of each parking area and the distance from the parking lot entrance and exit, the characteristic index of each parking area is obtained;

[0006] Divide the parking area into a long-term parking area category and a short-term parking area category based on characteristic indicators; obtain the initial charging standard for each parking area in each category according to the occupancy of all parking spaces in each category within a preset time period;

[0007] On the basis of the initial charging standard, the charging standard of each preset charging update node of each parking area in each category is obtained according to the traffic volume of each parking area in each category at the corresponding time of each preset charging update node, and the parking time of the vehicle at each preset charging update node.

[0008] Furthermore, the method for obtaining the characteristic index is:

[0009] For any parking area, the stability of the traffic flow in the parking area is obtained according to the parking time of each parking space in the parking area and the number of vehicles parked in each parking space within a preset time period;

[0010] The characteristic index of the parking area is obtained according to the stability of the traffic flow in the parking area, the total number of parking spaces in the parking area, and the shortest distance between the parking area and the entrance and exit of the parking lot; among which, the stability of the traffic flow and the shortest distance are positively correlated with the characteristic index, and the total number of parking spaces is negatively correlated with the characteristic index.

[0011] Furthermore, the method for obtaining the stability of the traffic flow is:

[0012] For any parking space in any parking area, the ratio of the total time duration of vehicles parked in the parking space within the preset time period to the total time duration of the preset time period is obtained as the first reference stability of the parking space;

[0013] The result of negative correlation and normalization of the number of vehicles parked in the parking space within a preset time period is used as the second reference stability of the parking space;

[0014] The product of the first reference stability level and the second reference stability level is used as the overall stability level of the parking space;

[0015] The average value of the overall stability of all parking spaces in the parking area is obtained as the traffic flow stability of the parking area.

[0016] Furthermore, the method for dividing the parking area into a long-term parking area category and a short-term parking area category based on the characteristic index is:

[0017] Classify all parking areas with characteristic indicators greater than or equal to a preset characteristic indicator threshold as long-term parking areas;

[0018] All parking areas with characteristic indicators less than the preset characteristic indicator threshold are classified as short-term parking areas.

[0019] Furthermore, the method for obtaining the initial charging standard is:

[0020] The preset time period is evenly divided into a plurality of partial time periods, and for any category, the number of vehicles parked in all parking spaces in the category at a specified time in each partial time period is obtained, which is taken as the first number;

[0021] The ratio of each first quantity to the total number of all parking spaces in the category is taken as the first eigenvalue;

[0022] The mean of all first eigenvalues ​​is taken as the parking space occupancy rate of this category;

[0023] The calculation formula for obtaining the initial charging standard for each parking area in each category based on the parking space occupancy rate is: ; In the formula, is the initial charging standard for each parking area in long-term parking area category h; is the initial charging standard for each parking area in short-term parking area category s; The default charging standards; The occupancy rate of parking spaces in the long-term parking area category; It is the parking space occupancy rate of the short-term parking area category.

[0024] Furthermore, the method for obtaining the charging standard of each preset charging update node of each parking area in each category of the vehicle is:

[0025] For any parking area in any category, when a vehicle is parked in the parking area for a period not exceeding the preset buffer period, the charging standard for the vehicle shall be the initial charging standard for the parking area;

[0026] When the parking time of the vehicle in the parking area exceeds the preset buffer period, a preset charging update node is obtained at each preset time interval with the end time of the preset buffer period as the starting point; wherein the end time of the preset buffer period is the first preset charging update node;

[0027] For any preset fee update node, the parking space shortage level of the parking area at the preset fee update node is obtained according to the occupancy of the parking spaces in the parking area at the corresponding time of the preset fee update node and the flow of vehicles on the peripheral roads of the parking area at the corresponding time of the preset fee update node;

[0028] Obtaining the length of a time period formed by the time corresponding to the preset fee update node and the initial time when the vehicle enters the parking area as the parking time of the vehicle corresponding to the preset fee update node;

[0029] The difference between the parking time of the vehicle at the preset fee update node and the preset buffer zone time is used as the reference time of the vehicle at the preset fee update node;

[0030] According to the parking space shortage degree and the reference time, obtaining the charging factor of the vehicle at the preset charging update node in the parking area;

[0031] The charging standard of the vehicle at the preset charging update node in the parking area is obtained according to the initial charging standard of the parking area and the charging factor of the vehicle at the preset charging update node in the parking area.

[0032] Furthermore, the method for obtaining the parking space shortage degree is:

[0033] Obtaining a ratio of the number of vehicles parked in the parking spaces of the parking area at the time corresponding to the preset fee update node to the total number of parking spaces of the parking area as the parking space occupancy rate of the parking area at the preset fee update node;

[0034] The product of the parking space occupancy degree and the number of vehicles on the peripheral roads of the parking area at the time corresponding to the preset fee update node is used as the parking space shortage degree of the parking area at the preset fee update node.

[0035] Furthermore, the calculation formula of the charging factor is: ; In the formula, The charging factor of the vehicle at the kth preset charging update node in the ath parking area in the long-term parking area category h; The charging factor of the vehicle at the kth preset charging update node in the ath parking area in the short-term parking area category s; is the parking space shortage level of the a-th parking area in the long-term parking area category h at the k-th preset fee update node; The parking time corresponding to the kth preset fee update node of the ath parking area in the long-term parking area category h of the vehicle; is the duration of the preset buffer segment; The reference duration of the vehicle at the kth preset fee update node in the ath parking area of ​​the long-term parking area category h; is the parking space shortage level of the a-th parking area in the short-term parking area category s at the k-th preset charging update node; The parking time corresponding to the kth preset fee update node of the ath parking area in the short-term parking area category s for the vehicle; is the reference duration of the kth preset charging update node of the vehicle in the ath parking area in the short-term parking area category s; norm is the normalization function.

[0036] Furthermore, the calculation formula of the charging standard is: ; In the formula, The charging standard of the kth preset charging update node for the vehicle in the ath parking area in the long-term parking area category h; The charging standard of the kth preset charging update node for the vehicle in the ath parking area in the short-term parking area category s; is the initial charging standard for each parking area in long-term parking area category h; The charging factor of the vehicle at the kth preset charging update node in the ath parking area in the long-term parking area category h; is the initial charging standard for each parking area in short-term parking area category s; The charging factor of the vehicle at the kth preset charging update node in the ath parking area in the short-term parking area category s.

[0037] In the second aspect, another embodiment of the present invention provides a regional time-based charging system for smart parking lots, the system comprising: a memory, a processor, and a computer program stored in the memory and running on the processor, and when the processor executes the computer program, the steps of any one of the above methods are implemented.

[0047] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation method, structure, features and effects of the regional time-based charging method and system for smart parking lots proposed by the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments. In the following description, different "one embodiment" or "another embodiment" does not necessarily refer to the same embodiment. In addition, specific features, structures or characteristics in one or more embodiments may be combined in any suitable form.

[0048] Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs.

[0049] The specific scheme of the regional time-based charging method and system for smart parking lots provided by the present invention is described in detail below with reference to the accompanying drawings.

[0050] Example 1: The specific scenario of this example is: It is known that the current smart parking lot adopts fixed parking fee standards for different parking areas. This charging strategy will cause a large number of vehicles to flow into parking areas with lower charging standards. There will be more vacant parking spaces in parking areas with higher charging standards, resulting in unbalanced utilization of parking space resources. It will definitely cause congestion during periods of heavy traffic. In actual situations, different car owners have different parking needs. Some car owners hope to park their cars in the parking lot for a long time, while some car owners only park their cars in the parking lot for a short time. In order to balance the needs of different car owners and better deal with the problem of unbalanced utilization of parking space resources, this embodiment analyzes the flow of vehicles in each parking area, as well as the scale and location distribution of each parking area, and divides the parking areas into two categories according to parking needs: long-term parking area category and short-term parking area category; then the parking space occupancy in each category is analyzed to obtain the initial charging standard for each parking area in each category; on the basis of the initial charging standard, the real-time dynamic charging strategy for each parking area is determined according to the parking time of the vehicle in each parking area and the traffic volume of each parking area, which indirectly changes the parking behavior of the car owners, is conducive to solving the problem of unbalanced use of parking spaces in different parking areas in the smart parking lot, makes the parking demand of different parking areas in the smart parking lot more reasonable, and effectively reduces the vehicle congestion in the smart parking lot.

[0051] This invention proposes a regional time-based charging method for smart parking lots. Figure 1 , which shows a schematic flow chart of a regional time-based charging method for a smart parking lot provided by an embodiment of the present invention, the method comprising the following steps:

[0052] Step S1: Obtain characteristic indicators of each parking area according to the parking situation of each parking space in each parking area in the smart parking lot within a preset time period, as well as the size of each parking area and the distance from the parking lot entrance and exit.

[0053] Specifically, this embodiment takes a smart parking lot as an example for analysis. It should be noted that all subsequent smart parking lots refer to this smart parking lot. In order to help car owners remember their parking positions in smart parking lots, parking spaces are divided into multiple different parking areas according to the distribution of parking spaces. Among them, each parking area contains multiple parking spaces, and the charging standards for all parking spaces in the same parking area are the same. Under normal circumstances, each car owner wants to park his car in a parking area that is close to the entrance and exit and has a low charging standard, resulting in a large number of vacant parking spaces in the parking area far from the entrance and exit in the smart parking lot, resulting in a waste of parking space resources. This embodiment takes into account the different parking needs of different car owners, and then sets a more reasonable dynamic charging strategy for each parking area. For car owners who need long-term parking, they are more inclined to parking areas with higher initial charging standards but lower parking charging standards as the parking time increases. For car owners who need short-term parking, they are more inclined to parking areas with lower initial charging standards but higher parking charging standards as the parking time increases. Therefore, dynamically adjusting the charging standards of parking areas according to the parking needs of car owners can make fuller use of parking spaces in parking areas.

[0054] In order to reduce the congestion of vehicles in smart parking lots, parking areas far from the entrances and exits should be selected as long-term parking areas; usually, there are fewer vehicles that stay for a long time than vehicles that stay for a short time, so smaller parking areas are more likely to be long-term parking areas; at the same time, when the number of vehicles parked in a parking area is relatively stable, it means that the parking area is also more likely to be a long-term parking area. In this embodiment, the characteristic index of each parking area is obtained according to the parking situation of each parking space in each parking area in the smart parking lot within a preset time period, as well as the size of each parking area and the distance from the entrance and exit of the parking lot. Among them, the larger the characteristic index, the more likely the corresponding parking area is to be a long-term parking area; the smaller the characteristic index, the more likely the corresponding parking area is to be a short-term parking area. In this embodiment, the preset time period is set to 30 days. The implementer can set the size of the preset time period according to the actual situation, which is not limited here.

[0055] It should be noted that in order to accurately analyze the parking situation of vehicles in each parking area and the traffic flow in each parking area, this embodiment sets a geomagnetic sensor on each parking space to determine the occupancy of parking spaces in each parking area, and sets a camera to monitor the number of occupied parking spaces in each parking area and the number of vehicles flowing on the peripheral roads corresponding to each parking area in real time. It should be noted that the peripheral roads corresponding to each parking area are divided in advance manually. At the same time, the license plate recognition system at the entrance and exit of the smart parking lot recognizes the license plate and records the entry and exit time of the corresponding vehicle. All acquired data are transmitted to the cloud platform for centralized processing, and the corresponding parking fee is calculated for each vehicle based on the dynamic charging strategy.

[0056] Preferably, in one possible implementation of this embodiment, the method for obtaining the characteristic index is as follows: Figure 2 , which shows a flow chart of a method for obtaining a characteristic indicator provided by this embodiment, the method comprising the following steps:

[0057] Step S201: For any parking area, the stability of the traffic flow in the parking area is obtained according to the parking time of each parking space in the parking area and the number of vehicles parked in each parking space within a preset time period.

[0058] When the parking time of vehicles parked in a parking area is longer and the mobility of vehicles is lower within a preset time period, it means that the owners of long-term parking are more willing to park their vehicles in the parking area, and the parking area is more suitable for being classified as a long-term parking area. Therefore, this embodiment obtains the stability of the traffic flow of the parking area according to the parking time of each parking space in the parking area and the number of vehicles parked in each parking space within the preset time period. The greater the stability of the traffic flow, the more suitable the parking area is for being classified as a long-term parking area.

[0059] Preferably, in a method that can be implemented in this embodiment, the method for obtaining the stability of vehicle flow is as follows: for any parking space in any parking area, obtain the ratio of the total duration of vehicles parked in the parking space within a preset time period to the total duration of the preset time period as the first reference stability of the parking space; the greater the first reference stability, the longer the duration of vehicles parked in the parking space; negatively correlate and normalize the number of vehicles parked in the parking space within the preset time period as the second reference stability of the parking space; the greater the second reference stability, the smaller the number of vehicles parked in the parking space and the lower the vehicle flow in the parking space. It should be noted that when the second reference stability is a maximum of 1, it means that no vehicle is parked in the parking space within the preset time period. This embodiment is achieved through The number of vehicles parked in the parking space within the preset time period is negatively correlated and normalized, where exp is an exponential function with a natural constant as the base, and x represents the number of vehicles parked in the parking space within the preset time period. In order to accurately analyze the parking stability of the vehicle in the parking space, the product of the first reference stability and the second reference stability is used as the overall stability of the parking space; the greater the overall stability, the more stable the vehicles parked in the parking space. In order to comprehensively analyze the stability of the vehicles parked in the parking area, the average of the overall stability of all parking spaces in the parking area is obtained as the vehicle flow stability of the parking area.

[0060] Step S202: Acquire characteristic indicators of the parking area according to the stability of the traffic flow in the parking area, the total number of parking spaces in the parking area, and the shortest distance between the parking area and the entrance and exit of the parking lot; wherein the stability of the traffic flow and the shortest distance are positively correlated with the characteristic indicators, and the total number of parking spaces is negatively correlated with the characteristic indicators.

[0061] It is known that the greater the stability of the known traffic flow, the more suitable the corresponding parking area is for being classified as a long-term parking area; when the total number of parking spaces in a parking area is smaller, the parking area is also more suitable for being classified as a long-term parking area; when the shortest distance between the parking area and the entrance and exit of the parking lot is larger, the parking area is also more suitable for being classified as a long-term parking area; furthermore, this embodiment obtains the characteristic index of the parking area according to the stability of the traffic flow in the parking area, the total number of parking spaces in the parking area, and the shortest distance between the parking area and the entrance and exit of the parking lot; wherein the stability of the traffic flow and the shortest distance are both positively correlated with the characteristic index, and the total number of parking spaces are negatively correlated with the characteristic index.

[0062] The calculation formula of the characteristic index is: ; In the formula, is the characteristic index of the jth parking area; is the stability of traffic flow in the jth parking area; is the shortest distance between the jth parking area and the parking lot entrance and exit; is the total number of parking spaces in the jth parking area; norm is the normalization function.

[0063] At this point, the characteristic indicators of each parking area are obtained.

[0064] Step S2: Divide the parking area into a long-term parking area category and a short-term parking area category based on characteristic indicators; obtain the initial charging standard for each parking area in each category according to the occupancy of all parking spaces in each category within a preset time period.

[0065] It is known that the larger the characteristic index, the more suitable the corresponding parking area is for being classified as a long-term parking area; the smaller the characteristic index, the more suitable the corresponding parking area is for being classified as a short-term parking area; and thus, this embodiment sets the preset characteristic index threshold value as 0.8, and the implementer can set the size of the preset characteristic index threshold value according to the actual situation, which is not limited here. Then, all parking areas with characteristic indexes greater than or equal to the preset characteristic index threshold value are classified as long-term parking area categories; and all parking areas with characteristic indexes less than the preset characteristic index threshold value are classified as short-term parking area categories. Therefore, the parking areas are accurately divided into long-term parking area categories and short-term parking area categories based on the characteristic indexes, so as to facilitate the customization of the subsequent dynamic charging strategy.

[0066] In actual situations, it is impossible to predict whether different car owners will park for a long time or a short time, and it is also unknown which parking area the car will be parked in. Therefore, this embodiment can only set different dynamic charging strategies for different parking areas to guide the parking behavior of car owners, so that parking space resources are used efficiently. For vehicles that need long-term parking, it is hoped that they will stay in the parking area in the long-term parking area category as much as possible. At the same time, in order to ensure that the parking spaces in the parking areas in the long-term parking area category are not occupied by short-term parking vehicles, therefore, the initial charging standard of each parking area in the long-term parking area category should be larger and decrease as the parking time increases. It should be noted that the initial charging standard of each parking area in the long-term parking area category is the same. For vehicles that need short-term parking, it is hoped that they will stay in the parking area in the short-term parking area category as much as possible. At the same time, in order to ensure that the parking spaces in the parking areas in the short-term parking area category are not occupied by long-term parking vehicles, therefore, the initial charging standard of each parking area in the short-term parking area category should be smaller and increase as the parking time increases. It should be noted that the initial charging standard of each parking area in the short-term parking area category is the same. At the same time, it is necessary to ensure that the initial charging standard of each parking area in the long-term parking area category must be greater than the initial charging standard of each parking area in the short-term parking area category to guide car owners to park reasonably.

[0067] In order to reasonably set the initial charging standard for each parking area in each category and ensure the revenue of the smart parking lot, this embodiment obtains the initial charging standard for each parking area in each category according to the occupancy of all parking spaces in each category within a preset time period.

[0068] Preferably, in one possible implementation of this embodiment, the method for obtaining the initial charging standard is as follows: Figure 3 , which shows a flow chart of a method for obtaining an initial charging standard provided by this implementation, the method comprising the following steps:

[0069] Step S301: Obtain parking space occupancy rate.

[0070] The higher the occupancy rate of parking spaces in a certain category, the greater the usage of parking spaces in this category. In order to appropriately increase the revenue of smart parking lots, the initial charging standard for each parking area in this category can be appropriately increased.

[0071] Among them, the method for obtaining the parking space occupancy rate is: divide the preset time period evenly into multiple local time periods. In this embodiment, the preset time period is divided into 30 local time periods, wherein the duration of a local time period is 24 hours a day. The implementer can set the number of divided local time periods according to the actual situation, which is not limited here. The purpose of dividing the preset time period into local time periods in this embodiment is to more accurately analyze the occupancy of parking spaces in each category in the future. Then, for any category, the number of vehicles parked in all parking spaces in the category at the specified time of each local time period is obtained, which is all taken as the first number; the larger the first number, the greater the degree of occupancy of the parking spaces in the category. Among them, in this embodiment, the specified time is set as the end time of each local time period, and the implementer can set the specified time according to the actual situation, which is not limited here. In order to analyze the occupancy of parking spaces in this category, the ratio of each first number to the total number of all parking spaces in this category is taken as the first characteristic value; then the average of all first characteristic values ​​is taken as the parking space occupancy rate of this category.

[0072] At this point, the parking space occupancy rate of the long-term parking area category and the parking space occupancy rate of the short-term parking area category are obtained respectively.

[0073] Step S302: Obtain the initial charging standard for each parking area in each category according to the parking space occupancy rate.

[0074] In order to obtain the initial charging standard for each parking area in each category, this embodiment first sets the preset charging standard for each parking area in the smart parking lot, wherein the preset charging standard for the parking spaces in each parking area is the same. This embodiment sets the preset charging standard to 5 yuan / hour. The implementer can set the size of the preset charging standard according to the actual situation, which is not limited here. Then the preset charging standard is adjusted by the parking space occupancy rate of each category to obtain the initial charging standard for each parking area in each category. It is known that the parking spaces in the long-term parking area category require a higher initial charging standard. When the parking space occupancy rate of the long-term parking area category is higher, it means that the parking spaces in the long-term parking area category are tight. The initial charging standard for the parking spaces in the long-term parking area category can be appropriately increased, that is, the preset charging standard is positively adjusted with the parking space occupancy rate of the long-term parking area category as the weight; when the parking space occupancy rate of the short-term parking area category is higher, it means that the parking spaces in the short-term parking area category are tight. The degree of fee reduction can be appropriately reduced on the basis of the preset charging standard.

[0075] The calculation formula for obtaining the initial charging standard for each parking area in each category through the parking space occupancy rate is: ; In the formula, is the initial charging standard for each parking area in long-term parking area category h; is the initial charging standard for each parking area in short-term parking area category s; The default charging standards; The occupancy rate of parking spaces in the long-term parking area category; It is the parking space occupancy rate of the short-term parking area category.

[0076] At this point, the initial charging standard for each parking space in each parking area in the long-term parking area category and the initial charging standard for each parking space in each parking area in the short-term parking area category are obtained respectively.

[0077] Step S3: On the basis of the initial charging standard, the charging standard of each preset charging update node of each parking area in each category is obtained according to the traffic volume of each parking area in each category at the corresponding time of each preset charging update node, and the parking time of the vehicle at each preset charging update node.

[0078] Specifically, this embodiment sets the preset buffer period to two hours. The implementer can set the duration of the preset buffer period according to the actual situation, and it is not limited here. During the first two hours when the vehicle is parked in the parking space, the initial charging standard of the corresponding parking area will be used for billing. If it is less than two hours, it will be charged according to the proportion of parking time. When the parking time exceeds two hours, it is necessary to set a dynamic charging strategy to ensure the coordination and reasonableness of the billing between the parked vehicles and the vehicles to be parked. Since the charging standard trends of long-term parking areas and short-term parking areas are different, the dynamic charging standard needs to be combined with the parking space occupancy in the corresponding parking area, the nearby traffic flow and the parking time. Among them, the charging strategies corresponding to the desired long-term parking areas and short-term parking areas should be as follows: Figure 4 As shown, Figure 4 This is a graph showing the changes in the charging standards for long-term and short-term parking areas as the parking duration changes. Figure 4 It can be seen that the initial charging standard of the long-term parking area is greater than that of the short-term parking area. As the parking time increases, the charging standard of the long-term parking area will gradually decrease, and the charging standard of the short-term parking area will gradually increase.

[0079] In order to determine different charging trends, for long-term parking areas, if the surrounding traffic volume and parking space occupancy rate are larger, the degree of decrease in charging standards should be appropriately reduced; for short-term parking areas, if the surrounding traffic volume and parking space occupancy rate are larger, the degree of increase in charging standards should be increased. At the same time, combined with the parking time of the vehicle, it is ensured that when the parking time is longer, the charging standard of the long-term parking area is lower, and the charging standard of the short-term parking area is higher. Therefore, on the basis of the initial charging standard, this embodiment obtains the charging standard of each preset charging update node of each parking area in each category according to the traffic volume of each parking area in each category at the corresponding time of each preset charging update node, and the parking time of the vehicle corresponding to each preset charging update node.

[0080] Preferably, in an achievable manner of the present embodiment, the method for obtaining the charging standard of each parking area in each category at each preset charging update node is as follows: for any parking area in any category, when the parking time of a vehicle in the parking area does not exceed the preset buffer period, the charging standard of the vehicle is the initial charging standard of the parking area; when the parking time of the vehicle in the parking area exceeds the preset buffer period, taking the end time of the preset buffer period as the starting point, a preset charging update node is obtained at each preset time interval; wherein the end time of the preset buffer period is the first preset charging update node; the present embodiment sets the preset time to one hour, and the implementer can set the size of the preset time according to the actual situation, which is not limited here;

[0081] For any preset fee update node, the parking space tension of the parking area at the preset fee update node is obtained based on the occupancy of the parking spaces in the parking area at the corresponding time of the preset fee update node and the flow of vehicles on the peripheral roads of the parking area at the corresponding time of the preset fee update node; when the parking space tension is greater, if the parking area is a long-term parking area, the degree of decrease in the charging standard of the vehicle at the preset fee update node in the parking area should be smaller, and if the parking area is a short-term parking area, the degree of increase in the charging standard of the vehicle at the preset fee update node in the parking area should be greater. Among them, the method for obtaining the parking space tension is: obtaining the ratio of the number of parked vehicles in the parking spaces of the parking area at the corresponding time of the preset fee update node to the total number of parking spaces in the parking area as the parking space occupancy of the parking area at the preset fee update node; taking the product of the parking space occupancy and the number of vehicles on the peripheral roads of the parking area at the corresponding time of the preset fee update node as the parking space tension of the parking area at the preset fee update node;

[0082] Obtain the length of the time period formed by the time corresponding to the preset fee update node and the initial time when the vehicle parks in the parking area as the parking time of the vehicle corresponding to the preset fee update node; it should be noted that the initial time when the vehicle parks in the parking area is the time when the vehicle enters the smart parking lot. The difference between the parking time of the vehicle corresponding to the preset fee update node and the length of the preset buffer segment is used as the reference time of the vehicle at the preset fee update node; wherein, the longer the reference time, if the parking area is a long-term parking area, the greater the degree of decrease in the charging standard of the vehicle at the preset fee update node in the parking area should be, and if the parking area is a short-term parking area, the greater the degree of increase in the charging standard of the vehicle at the preset fee update node in the parking area should be;

[0083] According to the parking space shortage degree and the reference time, the charging factor of the vehicle at the preset charging update node in the parking area is obtained; wherein the calculation formula of the charging factor is: ; In the formula, The charging factor of the vehicle at the kth preset charging update node in the ath parking area in the long-term parking area category h; The charging factor of the vehicle at the kth preset charging update node in the ath parking area in the short-term parking area category s; is the parking space shortage level of the a-th parking area in the long-term parking area category h at the k-th preset fee update node; The parking time corresponding to the kth preset fee update node of the ath parking area in the long-term parking area category h of the vehicle; is the duration of the preset buffer segment; The reference duration of the vehicle at the kth preset fee update node in the ath parking area of ​​the long-term parking area category h; is the parking space shortage level of the a-th parking area in the short-term parking area category s at the k-th preset charging update node; The parking time corresponding to the kth preset fee update node of the ath parking area in the short-term parking area category s for the vehicle; is the reference duration of the kth preset charging update node of the vehicle in the ath parking area in the short-term parking area category s; norm is the normalization function; it should be noted that the 1 in the formula is to avoid the reference duration being 0;

[0084] Then, based on the initial charging standard, the charging standard of the parking area and the charging factor of the vehicle at the preset charging update node in the parking area are used to obtain the charging standard of the vehicle at the preset charging update node in the parking area; wherein the charging standard is calculated as follows: ; In the formula, The charging standard of the kth preset charging update node for the vehicle in the ath parking area in the long-term parking area category h; The charging standard of the kth preset charging update node for the vehicle in the ath parking area in the short-term parking area category s; is the initial charging standard for each parking area in long-term parking area category h; The charging factor of the vehicle at the kth preset charging update node in the ath parking area in the long-term parking area category h; is the initial charging standard for each parking area in short-term parking area category s; The charging factor of the vehicle at the kth preset charging update node in the ath parking area in the short-term parking area category s.

[0085] At this point, the charging standards for each parking area in each category at each preset charging update node are obtained. Among them, the charging standards for each preset charging update node represent the charging standards for the next hour. If the vehicle leaves midway within the next hour, the length of time the vehicle stays in the next hour is obtained. If the length of stay exceeds half an hour, it is charged as one hour. If the length of stay does not exceed half an hour, no charge is made. At the same time, in order to ensure the parking freedom of car owners, all parking areas are open to all car owners. Long-term parking areas and short-term parking areas are only logically divided. In fact, in the smart parking lot, there is no mandatory distinction between the two major categories, and car owners can choose parking spaces by themselves.

[0086] In order to avoid extreme situations where the charging standards are too low or too high, and thus the parking lot revenue and the rights of car owners cannot be guaranteed, this embodiment ensures that the minimum charging standard for vehicles in the long-term parking area is not less than 0.5 times the initial charging standard of the long-term parking area, and the maximum charging standard for vehicles in the short-term parking area is not more than 1.5 times the initial charging standard of the short-term parking area; implementers can set the minimum charging standard in the long-term parking area and the maximum charging standard in the short-term parking area according to actual conditions, and there is no limitation here.

[0087] This embodiment can better balance the parking space resources in different parking areas by setting a dynamic parking space charging strategy, effectively avoiding the two extreme situations of severe shortage of parking spaces and excessive waste of parking spaces in the parking areas of the parking lot, and at the same time effectively reducing vehicle congestion, which is conducive to more reasonable management of the parking lot.

[0088] In summary, this embodiment obtains characteristic indicators of each parking area according to the parking situation of vehicles in the parking area within a preset time period, the size of the parking area, and the distance from the entrance and exit, and then divides the parking area into a long-term parking area category and a short-term parking area category; obtains the initial charging standard of each parking area according to the occupancy of parking spaces in each category; and obtains the charging standard of each preset charging update node of each parking area according to the vehicle flow of each parking area at the corresponding time of each preset charging update node and the parking time of the vehicle at each preset charging update node on the basis of the initial charging standard. By dynamically adjusting the charging standard of each parking area, the present invention can more reasonably allocate parking resources and effectively reduce the waste of parking space resources and vehicle congestion.
