detailed description

In order to make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be described clearly and completely in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of the embodiments of the present invention, not all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

In the following detailed description, reference may be made to the various drawings of the specification that are part of this application to illustrate specific embodiments of the application. In the drawings, similar reference numerals describe substantially similar components in different drawings. Each specific embodiment of the present application is described in sufficient detail below, so that a person of ordinary skill with relevant knowledge and technology in the field can implement the technical solution of the present application. It should be understood that other embodiments can also be used or structural, logical or electrical changes can be made to the embodiments of this application.

Fig. 1 is a flowchart of a parking space allocation method according to an embodiment of the present invention. According to one embodiment, a user who has applied for a fixed parking agreement such as a monthly pass, a quarter pass or an annual pass at the parking lot may be referred to as a priority user. Users who do not have such a fixed parking agreement can be called temporary users.

In step 102, the data of the parking spaces occupied by the priority user in the corresponding time period one or more days before the current date can be obtained. The time period here refers to a period of time of any length in a day, which can be the same as the unit time of the parking lot charge, for example, 15 minutes. The corresponding time period refers to the same time period of the day when multiple days are involved, such as 9:00-9:15 every day.

In step 104, the historical minimum remaining number of vehicles in the time period is determined according to the acquired data. In this application, the historical minimum remaining number of parking spaces refers to the number of remaining parking spaces in the parking lot when the priority user occupies the largest number of parking spaces in the parking lot during the corresponding time period one or more days before the current date. This concept is an important indicator proposed in this application, and a fixed value. The method of determining the minimum number of remaining parking spaces in history will be described in detail later.

In step 106, the number of parking spaces occupied by the temporary user in the corresponding time period in the current date is obtained.

In step 108, calculate the number of reusable parking spaces in the corresponding time period of the current date, where the number of reusable parking spaces in the corresponding time period of the current date is the historical minimum remaining number of parking spaces and the number of parking spaces occupied by the temporary user Difference. It is understandable that, as time goes by, the parking space occupied by temporary users during this time period can be a dynamic value. But no matter how it changes, the calculation method of the number of reusable parking spaces remains the same.

In step 110, it is determined whether the number of reusable vehicles is greater than zero.

When the number of reused parking spaces is greater than zero, in step 112, temporary user vehicles outside the parking lot may be allowed to enter.

When the number of reusable parking spaces is not greater than zero, in step 114, temporary user vehicles outside the parking lot may be prohibited from entering.

The following example introduces this method in detail.

According to an embodiment, it is assumed that there are 100 locations in a parking lot. According to the obtained historical parking data, it is found that in a specific time period, the number of parking spaces occupied by priority users may be 40 (but this does not mean that there are only 40 priority users, and it is likely to be more than 40). Therefore, the historical minimum remaining number of parking spaces is 60, which means that the number of parking spaces that can be reused during this time period does not exceed 60.

If the current parking situation is as shown in the current parking data 1, the temporary user's parking vehicle has already occupied 20 positions, so the current number of vehicles that can still be reused is 40 (that is, 60-20). This value greater than zero indicates that sufficient parking spaces have been reserved for priority users based on historical records to ensure that there should be no parking spaces when they come to the parking lot during the current time period. At the same time, the remaining 40 parking spaces can be reused or It is said that during this time period, 40 temporary users can still be admitted and parked.

If the current parking situation is as shown in the current parking data 2, there are already 60 parking spaces occupied by vehicles parked by temporary users, and the current number of reusable parking spaces is 0 (that is, 60-60). No more temporary users can be allowed to enter the parking lot, otherwise the supply of parking spaces for priority users may not be guaranteed.

Fig. 2a is a flowchart of a method for determining a historical minimum remaining parking space for a corresponding time period in a day according to an embodiment of the present invention.

In step 202, time and monitor vehicles entering and leaving the parking lot;

In step 204, it is determined whether the vehicle entering or leaving the parking lot is a priority user vehicle;

If it is a priority user vehicle, in step 206, record the number of parking spaces occupied by the priority user in the parking lot at the moment;

If it is not a priority user vehicle, jump back to step 202;

In step 208, it is determined whether the timing time meets the preset time period;

If the corresponding time period is not reached, jump back to step 202;

If the corresponding time period has been reached, in step 210, it is determined that the historical minimum remaining number of parking spaces in the time period is the difference between the total number of parking spaces in the parking lot and the maximum value of all priority user occupied parking spaces recorded in the corresponding time period.

According to another embodiment, the method of obtaining the historical minimum remaining number of vehicles in the corresponding time period of the day may also be as shown in FIG. 2b.

In step 222, the difference between the total number of parking spaces in the parking lot and the number of parking spaces occupied by the priority users in the parking lot is first used as the temporary minimum remaining parking space;

In step 224, time and monitor vehicles entering and leaving the parking lot;

Step 226: Determine whether the vehicle entering and exiting the parking lot is a priority user vehicle;

If it is not a priority user vehicle, jump back to step 224;

If it is a priority user vehicle, step 228, update the number of parking spaces occupied by priority users in the current parking lot, and calculate the difference between the total number of parking spaces in the parking lot and the number of parking spaces occupied by priority users in the parking lot;

In step 230, compare the difference obtained in step 228 with the temporary minimum remaining number of vehicles;

If the difference obtained in step 228 is greater than the temporary minimum remaining number of parking spaces, then in step 232, the temporary minimum remaining number of parking spaces is used;

If the difference obtained in step 228 is less than or equal to the temporary temporary minimum remaining number of parking spaces, then in step 234, the temporary minimum remaining number of parking spaces is updated using the difference;

In step 236, it is determined whether the timing duration meets the corresponding time period;

If the corresponding time period is not met, jump back to step 224;

If the corresponding time period has been met, in step 238, the temporary minimum remaining number of vehicles is taken as the historical minimum remaining number of vehicles in the corresponding time period.

The following examples illustrate the above method. Assuming that the total number of parking spaces in the parking lot is 100, the temporary minimum remaining number of parking spaces changes according to the priority user's vehicle entry and exit conditions as shown in the following table. If the corresponding time period has arrived in the last column, the temporary minimum remaining number of vehicles shown in the last column will be used as the historical minimum remaining number of vehicles in the time period.

暂时最小剩余车位数Temporary minimum remaining parking spaces	100100	9999	9999	9999	9898	9797	9797	……...

According to an embodiment, the parking data collected by the system may have a time attribute. The time attribute may be divided according to working days or rest days, for example. Of course, other standard divisions can also be used. For example, the time attribute can be not only for days, but also for hours, such as morning hours or evening hours. The same time period refers to the corresponding time period in the days with the same time attribute (for example, all working days or all rest days). The parking data in the same time period is the same data. For example, the parking data between 8:00-8:15 a.m. on the first working day of a certain month and 8:00-8:15 a.m. on the working day of the second week or other months or other working days of other years are of the same type data. According to statistics, historical data with the same time attribute as the current time period has a higher reference value than historical data with different time attributes.

As described above, historical data may not only be parking data within a day, but may be data for days, months, or even years. According to a simple embodiment, the value with the smallest value of the historical minimum remaining number of parking spaces in the multi-day parking data can be selected as the historical minimum remaining number of parking spaces in the corresponding time period. According to other embodiments, the above-mentioned method for determining the historical minimum remaining number of vehicles in the preset corresponding time period may further include the step of averaging, weighting or correcting multiple historical data.

According to an embodiment, the minimum remaining number of parking spaces in a preset corresponding time period in m days with similar time attributes can be selected, and the weighted average historical minimum remaining number of parking spaces a

Among them, m is the number of days selected from the historical data that includes the preset corresponding time period, m≤365, n _i is the historical minimum remaining number of vehicles in the preset time period, i is an integer greater than or equal to 1 and less than or equal to m, and the weight coefficient

The greater the number of days m selected, the greater the weight w.

According to another embodiment, based on at least the weighted average historical minimum remaining number of vehicles a and the historical minimum remaining number of vehicles in the corresponding time period of the day before the current date, the revised weighted average historical minimum may be calculated for the predetermined corresponding time period. The number of remaining parking spaces.

Specifically, the weighted average historical minimum remaining parking space a and the historical minimum remaining parking space b of the day before the current date can be used to calculate the revised weighted average historical minimum remaining parking space h for the corresponding time period.

The day before the current date can be a day included in m days or not included in m days. Of course, the previous day here must have the same time attribute as the current date. According to one embodiment, this previous day may refer to the day immediately before the current date.

The effect of this correction is to find a balance between the burst period (by incorporating the data of the day before the current date) and historical data, thereby improving the accuracy of the estimation. Of course, not only the data of the day before the current date can be used for correction, but also the parking data of other dates can be used for correction.

According to one embodiment, when calculating the current reusable parking space, not only the historical minimum remaining number of parking spaces can be considered, but also the safety threshold can be increased according to the requirements of the parking lot manager. For example, on the basis of the historical minimum remaining parking space statistics, the priority parking user is forced to reserve a certain number of parking spaces, and the safety threshold is less than or equal to the number of priority users. If the current number of reusable parking spaces is greater than the safety threshold, temporary users outside the parking lot are allowed to enter the parking lot. If the current number of reusable parking spaces is less than or equal to the safety threshold, temporary users outside the parking lot are prohibited from entering the parking lot.

According to an embodiment, this safety threshold may be selected as a certain ratio of the total number of parking spaces, such as 10% or a certain ratio of the number of priority parking users, such as 20%. Of course this ratio is adjustable. According to an embodiment, the parking lot manager can select the size of the safety threshold according to the actual situation.

Fig. 3 is a flowchart of a parking space allocation method according to an embodiment of the present invention. The steps in FIG. 3 and in FIG. 1 with similar numbers are connected to each other, and will not be repeated here.

Step 310: Calculate two indicators X ₀ and X ₁ , where

X ₀ ＝hcp (3)

X ₁ =dec (4)

h is the revised weighted average historical minimum remaining parking spaces (of course, weighted average historical minimum remaining parking spaces can also be used, or single-day historical minimum remaining parking spaces or other types of historical minimum remaining parking spaces), c is the current temporary user The number of occupied parking spaces, p is the safety threshold set for priority users, d is the total number of parking spaces, e is the total number of priority users, and p is less than or equal to e.

In step 312, it is determined whether X ₀ or X ₁ is greater than zero;

If at least one of X ₀ or X ₁ is greater than zero, in step 314, temporary user vehicles outside the parking lot are allowed to enter the parking lot;

If both X ₀ and X ₁ are less than or equal to zero, then in step 316, the temporary user vehicle outside the parking lot is denied to enter the parking lot.

X ₁ represents the remaining parking spaces when all priority users in the area occupy the parking spaces at the same time. Since X _{1 is} greater than zero, it means that parking spaces that can meet the parking needs of all priority users are reserved. The remaining parking spaces outside the parking spaces occupied by temporary users can be used for reuse.

Since X ₀ is calculated based on historical data, there may be errors. Therefore, considering X ₀ and X ₁ at the same time, as long as one of them is greater than zero, temporary users outside the parking lot can be allowed to enter the parking lot. In this way, the safety threshold and the total number of priority users are considered at the same time, and the accuracy of parking space reuse is improved.

According to another embodiment, the priority users can be subdivided, for example, into a first priority user or VIP1, and a second priority user or VIP2. According to an embodiment, the parking lot may be a parking lot in a residential community, and the first priority parking user may be a parking user who lives in this community and has a monthly, quarterly or annual card. The second priority users may refer to users who are not residents of the community but who have applied for monthly, quarterly or annual parking cards. Temporary users refer to non-residents who come to park temporarily and do not apply for monthly, quarterly or annual cards. Of course, the types of users can also be divided according to different standards.

According to an embodiment, the priority of three kinds of users can be formulated in this way, the first priority user has priority over the second priority user, and the second priority user has priority over the temporary user. First, ensure the parking demand of the first priority user VIP1, and then give priority to the parking demand of the second priority user. After meeting the parking needs of the above two priority users, the parking needs of temporary users will be considered.

According to an embodiment, in the case of subdividing priority users, the aforementioned security threshold can also be subdivided into p1 and p2, and p1 can be a common security threshold for the first and second priority users, p2 may be a security threshold for the first priority user terminal.

Fig. 4 is a flow chart of a parking space allocation method according to an embodiment of the present invention. The steps in FIG. 4 with similar reference numerals in FIG. 1 or FIG. 3 are the same as each other, and will not be repeated here.

In step 410, two indicators Y ₀ and Y _{1 are} calculated, where

Y ₀ =hc-p1 (5)

Y ₁ =dfgc (6)

Where h is the revised weighted average historical minimum remaining parking spaces (of course, the weighted average historical minimum remaining parking spaces can also be used, or the single-day historical minimum remaining parking spaces or other types of historical minimum remaining parking spaces), and c is the current temporary The number of parking spaces occupied by users, d is the total number of parking spaces, f is the total number of first priority users, g is the total number of second priority users, p1 is the safety threshold set by the first and second priority users, and p1 is less than or equal to the sum of f and g;

In step 412, it is determined whether Y ₀ or Y ₁ is greater than zero;

If any one of Y ₀ and Y ₁ is greater than zero, in step 414, an off-site temporary user vehicle is allowed to enter.

If Y ₀ and Y ₁ are not greater than zero, in step 416, calculate the other two indicators Y ₂ and Y ₃ , where

Y ₂ = hc-p2 (7)

Y ₃ ＝dfc (8)

Where p2 is the safety threshold set by the first priority user, and p2 is less than or equal to f.

In step 418, it is determined whether Y ₂ or Y ₃ is greater than zero.

If Y ₂ and Y ₃ are not greater than zero, then step 419, the temporary users outside the parking lot and the vehicles of the second priority user are denied to enter the parking lot.

If at least one of Y ₂ and Y ₃ is greater than zero, then in step 420, vehicles of off-site temporary users are prohibited from entering the parking lot, and only the vehicles of the first and second priority users are allowed to enter the parking lot.

By subdividing priority users and formulating different thresholds, it is possible to reduce the impact on the demand for parking spaces of residents in the community while ensuring the reuse of parking spaces.

According to an embodiment, the present application also provides a parking space allocation system for executing the above method. As shown in FIG. 5, it may include, for example, a processing module 502, a storage module 504, a communication module 506, and optionally, a vehicle monitoring system. Module 508, yard access control module 510. According to an embodiment, the vehicle monitoring module may monitor the number and attributes of vehicles entering and leaving the parking lot, and store the detection results in the storage module. Of course, according to other embodiments, the system can obtain historical parking data or the number of first or second priority users from other data centers through the communication module, and provide the data to the storage module or processing module. The storage module can be configured to calculate and generate historical minimum remaining parking spaces, weighted average historical minimum remaining parking spaces, revised weighted average historical minimum remaining parking spaces, reusable parking spaces, etc., and generate corresponding instructions, such as allowing Or prohibit the entry of temporary users' vehicles outside the venue, etc. According to an embodiment, the parking lot access management module can manage the vehicles allowed to enter and exit the parking lot according to the instructions of the processing module.

According to an embodiment, the present application also provides a storage medium on which a series of instructions executable by a computing device are stored. When these instructions are executed, a series of operations in the above method can be performed.

The above-mentioned embodiments are only used to illustrate the present invention, not to limit the present invention. Those of ordinary skill in the relevant technical field can make various changes and modifications without departing from the scope of the present invention. Therefore, all The equivalent technical solutions should also belong to the scope of the disclosure of the present invention.
