The embodiment of the application provides a parking management method, which comprises the steps of obtaining parking preference of a vehicle according to historical parking data of the vehicle, predicting an idle parking space corresponding to a specific time period according to past parking space data of a parking lot, matching the parking preference of the current vehicle with a prediction result of the idle parking space of the current time period, determining a candidate parking space of the vehicle corresponding to the current vehicle, and recommending the candidate parking space and a guide route to a guide terminal corresponding to the current vehicle according to the candidate parking space.

Referring to fig. 1, fig. 1 is a schematic view of an application scenario of a parking management method according to an embodiment of the present application. The parking management method is used for intelligently recommending the parking scheme after the vehicle enters the parking lot in real time. The device for executing the parking management method can be an electronic device, and the electronic device can be arranged in a parking lot or on a vehicle. For a scene that the electronic equipment is arranged in a parking lot, when a vehicle enters the parking lot, the electronic equipment captures vehicle information through the information acquisition device, generates a recommended parking scheme of the vehicle through the parking management method provided by the embodiment of the application, and sends the recommended parking scheme to a guidance terminal of the vehicle so as to guide the vehicle to park in a proper area in the parking lot; for the scene that the electronic equipment is arranged on the vehicle, when the vehicle enters the parking lot, the electronic equipment collects parking lot information through the information collection device, such as the mark of the parking lot, identifies the parking lot, generates the recommended parking scheme of the vehicle through the parking management method provided by the embodiment of the application, sends the recommended parking scheme to the guide terminal of the vehicle, and then guides the vehicle to park in a proper area in the parking lot.
It should be noted that, a parking lot may include a plurality of parking areas, such as an area a, an area B, an area C, and an area D, where there may be differences in the total number of parking spaces, the types of parking spaces (parking spaces, side parking spaces, etc.) and the number of parking spaces of each type, the distribution of parking spaces, and the like in each parking area, and the parking positions of vehicles in the parking lot are directly related to the habit preference and parking space conditions of the vehicle owner. Two situations generally exist when a car owner parks in a parking lot, one is that a parking area is taken as a first consideration, the car is parked in an area which can provide convenience for work or life of the car owner, for example, the car owner stays in an area A, and for the convenience of life, the car owner can preferentially search for a parking space in the area A; the other is that the parking mode is taken as a first consideration, a parking space to be reserved or a parking space to be arranged on the side in the parking lot is selected for parking, for example, if a car owner only excels in parking on the side, the car owner can preferentially select the parking space on the side in the parking lot for parking. The parking management method provided by the embodiment of the application can well identify whether the car owner takes the parking area as the first consideration or the parking mode as the first consideration, and provides a parking scheme for the car in a targeted manner by combining the free parking space prediction result corresponding to the parking time, so that the parking efficiency and the parking satisfaction degree are improved.
It should be noted that the application scenario schematic diagram of the parking management method shown in fig. 1 is only an example, various scenarios described in the embodiment of the present application are for more clearly illustrating the technical solution of the embodiment of the present application, and do not constitute a limitation on the technical solution provided in the embodiment of the present application, and as a person having ordinary skill in the art knows that along with the evolution of the parking management technology and the occurrence of a new business scenario, the technical solution provided in the embodiment of the present application is also applicable to similar technical problems, and the following detailed descriptions are separately provided. It should be noted that the following description of the embodiments is not intended to limit the preferred order of the embodiments.
Referring to fig. 2, fig. 2 is a flowchart of a parking management method provided in an embodiment of the present application, where the parking management method integrates two factors, namely a parking preference of a vehicle and a parking space vacancy corresponding to a current time, and recommends an optimal parking scheme for the vehicle, so that a convenience requirement of a vehicle owner is met, and a parking efficiency is improved. The parking management method comprises the following steps:
step S101, obtaining parking preferences corresponding to a current vehicle, wherein the parking preferences comprise a parking space preference sequence of the current vehicle in a parking lot.
It should be noted that the flink technology is used throughout the process of acquiring the parking preference corresponding to the current vehicle, and the technology can reduce the memory space requirement on the acquisition unit and improve the fluency of the acquisition unit for acquiring the parking preference corresponding to the current vehicle.
Specifically, the step of obtaining the parking preference corresponding to the current vehicle includes:
historical parking data of the current vehicle in the parking lot is acquired, and the historical parking data refers to parking data of the vehicle in the parking lot in a past period of time, for example, data of the current vehicle parking in the parking lot in the last six months. The method for acquiring the historical parking data can be as follows: firstly, obtaining a parking image of a current vehicle in the parking lot for a period of time in the past, wherein the parking image can be a parking video or a parking photo; then, the parking image is analyzed to obtain the vehicle information (such as the license plate number and the license plate color) of the current vehicle, the parking area, the parking space and the parking mode (such as the reverse parking or the side parking) of the current vehicle. It should be noted that the parking image is an image of the current vehicle after parking in the parking lot or during parking, and is an image that can determine a specific parking position of the current vehicle.
And determining the parking preference corresponding to the current vehicle according to the historical parking data. It should be noted that the historical parking data of the vehicle in the parking lot includes the personal preference information of the owner driving the vehicle, and the personal preference of the owner can be accurately obtained by analyzing the historical parking data, so that the parking preference corresponding to the current vehicle is obtained. The specific method comprises the following steps: and processing the historical parking data to obtain the number of times of parking in the garage of the current vehicle, the number of times of parking in the side of the current vehicle and the number of times of parking in the parking space corresponding to each parking space of the current vehicle. And determining the preference priority of the current vehicle according to the ratio of the number of times of parking for backing the garage and the number of times of parking for the side, for example, determining that a parking area is a first preference priority or a parking mode is a first preference priority according to the ratio. Determining the parking preference of the current vehicle according to the preference priority and the parking times of the parking spaces; for example, when the parking area is in the first preference priority, the parking areas are sorted according to the parking times of the current vehicle to obtain an area sequence, the parking spaces in the parking areas are sorted according to the area sequence and the parking times of the parking spaces to obtain a parking space preference sequence, and then the parking preference of the current vehicle is determined according to the parking space preference sequence; or when the parking mode is the first preference priority, the parking spaces are sequenced according to the parking mode of the vehicle and the parking times of the parking spaces to obtain the parking space preference sequence, and then the parking preference of the current vehicle is determined according to the parking space preference sequence.
The method for determining the preference priority of the current vehicle according to the ratio of the number of times of parking in the garage dumping mode to the number of times of parking in the side direction can be as follows: setting a first threshold range, wherein the first threshold range comprises a first upper threshold and a first lower threshold. When the ratio of the number of times of parking in the garage and the number of times of parking on the side is smaller than the first lower threshold value, determining that the parking on the side is a first preference priority and the parking area is a second preference priority; it should be noted that, the ratio is smaller than the first lower threshold, which indicates that the vehicle is currently parked in a manner of mainly parking in a side parking manner in a past period of time, and parking in a manner of parking in a reverse garage is rarely adopted, which reflects that the vehicle owner is relatively good at parking in the side parking manner, so that the side parking is taken as a priority for preference of the vehicle. When the ratio of the number of times of parking for backing the garage to the number of times of parking for the side direction is larger than the first upper threshold value, determining that parking for backing the garage is a first preference priority, and determining that a parking area is a second preference priority; similarly, the ratio is greater than the first upper threshold, which indicates that the current vehicle is mainly parked in a reverse garage manner in the past period of time, and rarely parked in a side garage manner, which reflects that the vehicle owner is relatively good at parking in the reverse garage, so that parking in the reverse garage is taken as a priority for the preference of the vehicle. When the ratio of the number of times of parking in the garage dumping mode to the number of times of parking in the side direction is within the first threshold value range, determining that the parking area is a first preference priority and the parking mode is a second preference priority; it should be noted that, the ratio is within the first threshold range, which indicates that the number of times of reverse parking and the number of times of lateral parking of the current vehicle in the past period are equivalent, and reflects that the vehicle owner can accept both parking manners, so the parking area is taken as the priority of the preference of the vehicle.
Optionally, the first lower threshold is 0.2, the first upper threshold is 5, and the first threshold range is 0.2 to 5. In combination with big data analysis, it can be known that setting the first threshold range in this embodiment can accurately determine whether the vehicle owner is parking mainly in a parking manner or mainly in a parking area.
It should be noted that, by the above method, the parking preferences corresponding to all vehicles parked in the parking lot in the past period can be obtained, and the parking preferences corresponding to the vehicles are stored in one storage medium; when the vehicle enters the parking lot, the vehicle is identified through the license plate number and the license plate color, and the parking preference corresponding to the vehicle is obtained from the storage medium.
Step S102, obtaining an idle parking space prediction result corresponding to the current time, wherein the idle parking space prediction result comprises the parking space vacancy rate of the parking space in the parking lot.
It should be noted that the flink technology is used throughout the process of obtaining the free parking space prediction result corresponding to the current time, and the technology can reduce the memory space requirement on the obtaining unit and improve the fluency of obtaining the free parking space prediction result corresponding to the current time by the obtaining unit.
The free parking space prediction result is obtained on the basis of analyzing the parking space image data of the parking lot in a past period of time, and reflects the free probability of the parking spaces of each parking space in the parking lot corresponding to each period of time; if the vacant parking space in the time period corresponding to the current time is displayed in the vacant parking space prediction result, the probability that the parking space is vacant at the current time is high.
Specifically, before the step of obtaining the free parking space prediction result corresponding to the current time, the method further includes determining a parking space vacancy rate of each parking space in the parking lot corresponding to each time period, and the method includes:
and acquiring parking space data of the parking lot in a past time interval, wherein the parking space data comprises parking space identification of the parking space and idle indexes of the parking space in a preset time period. Specifically, the method for acquiring the parking space data comprises the following steps: in the past time interval, the parking space images corresponding to the parking spaces in the parking lot can be videos or photos collected by a collecting device. Analyzing the parking space image to obtain information such as a parking space identifier of a parking space and an idle index of the parking space in a preset time period; the idle index refers to whether the parking space is idle or not idle within the preset time period; the method for judging whether the parking space is free or not comprises the following steps: judging whether a vehicle stops at the parking space within the preset time period or not, if so, judging that the parking space is not idle within the preset time period, otherwise, judging that the parking space is not idle within the preset time period; the preset time period can be set according to actual requirements, and is not limited here. And determining parking space data of the parking lot in the past time interval according to information obtained by analyzing the parking space images.
And calculating the statistical number of the preset time periods contained in the past time interval. It should be noted that the past time interval refers to a past time interval, for example, six months in the past is a past time interval; the preset time period refers to a specific time period, for example, a time period from 0 to 1 point of each day; the statistical number of the preset time periods included in the past time interval refers to how many preset time periods coexist in the preset time interval, for example, the preset time interval is six months in the past, the preset time period is 0 to 1 point every day, and then the preset time interval includes 180 preset time periods from 0 to 1 point in total, that is, the statistical number of the preset time periods included in the past time interval is 180.
And according to the idle index of the parking space in the preset time period, counting the idle times of the parking space in the past time interval. As mentioned above, the idle indexes of the parking space in the preset time period include idle and non-idle, and the number of times that the parking space is idle corresponding to the preset time period in the past time interval is counted and marked as idle times. For example, the past time interval is six months in the past, the preset time period is from 0 to 1 point every day, 180 time periods from 0 to 1 point are total, in the 180 time periods from 0 to 1 point, 120 time periods from 0 to 1 point are total, the parking space is free, and the number of free times of the parking space in the past time interval is 120.
And comparing the idle times with the statistical quantity to obtain the parking space idle rate of the parking space corresponding to the preset time period. For example, the past time interval is six months in the past, the preset time period is 0 to 1 point every day, the statistical number of the preset time periods included in the past time interval is 180, the number of idle times of the parking space corresponding to the preset time period in the past time interval is 120, and the idle rate of the parking space corresponding to the preset time period is as follows: 120/180= 66.7%.
And obtaining an idle parking space prediction result corresponding to the preset time period according to the parking space idle rate. It should be understood that, by the above method, the parking space vacancy rates of the parking spaces in the parking lot corresponding to the time periods may be obtained, and the free parking space prediction result may be a quantitative index represented by the parking space vacancy rates.
It should be noted that the free parking space prediction result obtained by the above method may be stored in a storage medium, and the step S102 obtains the free parking space prediction result from the storage medium. Specifically, the step S102 includes: acquiring current time, wherein the current time refers to the time when the current vehicle enters a parking lot; and determining the free parking space prediction result corresponding to the current time according to the corresponding relation between the current time and the preset time period, for example, if the vehicle enters the parking lot at a ratio of 0:15, and the preset time period corresponding to the current time is from 0 point to 1 point, the free parking space prediction result corresponding to the current time is the free parking space prediction result from 0 point to 1 point in the time period.
And S103, matching the parking preference with the free parking space prediction result to obtain a vehicle candidate parking space corresponding to the current vehicle.
Specifically, the step S103 includes: determining a parking space preference sequence of the current vehicle in a parking lot according to the parking preference; the parking space preference sequence is a result of sequencing parking spaces in the parking lot according to the parking preference of the current vehicle; the more preferred parking spaces of the current vehicle are ranked more ahead in the parking space preference sequence. And matching the parking space vacancy rate of each parking space corresponding to the current time in the parking space preference sequence. Determining the parking spaces with the parking space vacancy rate larger than a second threshold value at the current time as vehicle candidate parking spaces corresponding to the current vehicle; optionally, the second threshold is 60%, that is, the parking space vacancy rates of the candidate parking spaces of the vehicle at the current time are all greater than 60%, and the probability that the parking space is actually vacant at the current time can meet the parking expectation of the vehicle owner by combining big data analysis.
And step S104, recommending the candidate parking space and a guiding route to a guiding terminal corresponding to the current vehicle according to the candidate parking space.
Optionally, the candidate slots may include a plurality of slots. The step of recommending the candidate parking space and the guide route to the guide terminal corresponding to the current vehicle according to the candidate parking space comprises the following steps: sequentially recommending the candidate parking spaces to the guide terminal according to the sequence calibrated by the parking space preference sequence; and when the candidate parking spaces ranked in the front in the parking space preference sequence are not idle actually, recommending the candidate parking spaces ranked in the back in the parking space preference sequence to the guide terminal, and generating a guide route corresponding to the candidate parking spaces.
In summary, the parking management method provided by the embodiment of the application includes obtaining parking preference of a vehicle according to historical parking data of the vehicle, predicting an idle parking space corresponding to a specific time period according to past parking space data of a parking lot, matching the parking preference of the current vehicle with a prediction result of the idle parking space of the current time period, determining a candidate parking space of the vehicle corresponding to the current vehicle, and recommending the candidate parking space and a guidance route to a guidance terminal corresponding to the current vehicle according to the candidate parking space. The parking management method integrates the factors of the parking preference of the vehicle and the free parking space prediction result of the current time period to determine the candidate parking space, and recommends the optimal parking scheme for the vehicle owner, so that the convenience requirement of the vehicle owner is met, and the parking efficiency is improved.
