Description

Technical Field

[0001] The present invention relates to the technical field of parking management, and in particular to a parking space sharing system. Background Art

[0002] With the acceleration of urbanization and the surge in the number of private cars, the shortage of parking spaces has become a key factor restricting the quality of life of urban residents and the efficiency of urban traffic operations. This problem not only increases the daily travel pressure of residents, but may also lead to increased traffic congestion and environmental pollution. In order to meet these challenges, government departments, urban planners, and commercial organizations are actively exploring and implementing a series of innovative solutions, including but not limited to increasing parking facilities and setting up smart parking systems. Increasing parking facilities means expanding parking capacity by building more public parking lots and underground parking garages. Setting up smart parking systems means using advanced information technology, such as mobile applications and sensors, to optimize the allocation and monitoring of parking spaces. However, the construction cost of the former solution is relatively high, especially with the shortage of land resources in the city, and even if additional parking lots are built, it is difficult to meet user needs in a short period of time. The latter solution has limited optimization effect on the number of parking spaces and is also difficult to meet user needs.

[0003] Observing the parking situation in major cities, we can find that vehicle movement and parking demand changes mostly occur during peak hours in the morning and evening. A private parking space is often parked from the evening to the next day's breakfast, and is idle almost throughout the day. On the other hand, there are also many vehicles that need to travel and park during the day, and most open parking lots and public parking lots are often occupied in large numbers during this time period, making it difficult to find a parking space. For this reason, some parking lot management agencies and planning agencies have proposed a management method that uses private parking spaces as temporary parking spaces during restricted time periods, namely shared parking spaces.

[0004] However, there are many problems with the management of shared parking spaces that are currently proposed or currently in existence. In particular, after private parking spaces are shared, they are often occupied for a long time, affecting the normal parking of the original parking space owner. The current shared parking space management model affects the experience of the original parking space owner, and it is difficult or even impossible to generate benefits, which further limits the promotion and application of the shared parking space management model. Summary of the invention

[0005] In view of the problems existing in the prior art, the present invention provides a parking space sharing system, which can improve the utilization rate of parking spaces and reduce the use cost of parking spaces.

[0006] The technical solution of the present invention is achieved in this way:

[0007] A parking space sharing system is applied to a parking lot, wherein the parking lot is provided with a vehicle identification device; the parking lot is provided with a private parking space and a car moving robot; the vehicle identification device is communicatively connected with the system to identify whether the private parking space is occupied; the system includes a map module and a sharing module;

[0008] The map module includes a public map outside the parking lot and a parking lot map; the parking lot map has specific layout information of the private parking space; the specific layout information includes the status of the private parking space; the status includes shared and occupied;

[0009] The first car owner shares his private parking space during an idle time period through the sharing module; the idle time period includes a start sharing time and an end sharing time; one private parking space corresponds to one idle time period, and the idle time periods of all private parking spaces may be the same or different.

[0010] The first car owners referred to here usually refer to those parking space owners who drive their vehicles out of the parking lot during weekdays and other periods. The parking spaces of such car owners are often idle for a long period of time when their vehicles are not there, which provides the possibility of sharing parking spaces.

[0011] When a vehicle is parked in the private parking space, the state is occupied; when no vehicle is parked in the private parking space and the space is in an idle time period, the state is shared;

[0012] The second vehicle owner parks the vehicle temporarily in the private parking space located in a shared state according to the map module;

[0013] If the temporary vehicle is parked in the private parking space and exceeds the end time of sharing, the system controls the vehicle moving robot to transfer the temporary vehicle to another private parking space in the shared state.

[0014] By sharing private parking spaces during idle time periods, the utilization rate of parking spaces can be effectively improved; at the same time, by sharing private parking spaces, owners of temporarily parked vehicles can be charged, forming a new revenue source for owners of private parking spaces, and the income generated can reduce the cost of purchasing and maintaining parking spaces; some temporary vehicles will occupy parking spaces for an extended period of time due to some subjective or objective reasons. When the sharing time ends, the temporary vehicles can be automatically moved away by a car-moving robot to ensure that private parking spaces are available in a timely manner and avoid occupation problems.

[0015] As a further optimization of the above solution, the parking lot is also provided with dispatch parking spaces; the parking lot map has specific layout information of the dispatch parking spaces;

[0016] When transferring a vehicle, if all of the private parking spaces are occupied by vehicles, the temporary vehicle will be transferred to the dispatch parking space.

[0017] Dispatch parking spaces can only be used to transfer temporary vehicles already parked in the parking lot, and cannot be used as shared temporary parking spaces or private parking spaces. Dispatch parking spaces are set up as emergency backup to avoid the inability to dispatch temporary vehicles due to the lack of shared parking spaces, ensuring that vehicles have a place to park.

[0018] As a further optimization of the above solution, the system also includes a reservation module; the status also includes reservation; the second car owner uses the reservation module to make a reservation for a private parking space whose status is shared, and at this time the status of the private parking space is changed from shared to reserved.

[0019] As a further optimization of the above solution, when sharing the private parking space, the first car owner sets the start sharing time and the end sharing time through the sharing module;

[0020] Or the system automatically generates the start sharing time and the end sharing time for each shared private parking space.

[0021] The first car owner can customize the sharing time period, or the system can automatically generate a sharing time period for any private parking space based on the parking lot management method; when both are used at the same time, the user-defined time period has a higher priority.

[0022] As a further optimization of the above solution, the system also includes a data acquisition module, a data storage module and a prediction module;

[0023] The vehicle identification device includes a camera; the parking lot is provided with a gate and the camera at the entrance and exit; the camera has a license plate recognition function; the data acquisition module collects the time when each first car owner drives the vehicle out of the parking lot and the time when he returns to the parking lot every day according to the camera, and records it as the departure time and return time; that is, when the vehicle enters and exits the entrance and exit, the camera will upload the vehicle identification license plate number to the data acquisition module for storage, and simultaneously record the time while saving. According to the departure time and return time, it can be understood whether the first car owner's vehicle occupies a private parking space.

[0024] Each of the private parking spaces corresponds to an identification number and a license plate number;

[0025] The data storage module is provided with an entry and exit record table; each record in the entry and exit record table includes the identification number, the license plate number, the departure time, the return time and date;

[0026] The prediction module predicts the departure time and the return time of each private parking space on each day according to the entry and exit record table to obtain a prediction result; the sharing module automatically generates the start sharing time and the end sharing time for the private parking space according to the prediction result;

[0027] Each record in the entry and exit record table also includes the prediction result.

[0028] If the user does not customize the shared time period, the automatically generated shared time period will be used by default; otherwise, the customized shared time period will be used directly.

[0029] As a further optimization of the above scheme, the prediction results include predicted departure time and predicted return time;

[0030] The prediction result is calculated as:

[0031]

[0032] Where n is the number of private parking spaces, i∈[1,n]; m is the number of dates, j∈[1,m]; LeaveTime i,j ReturnTime represents the departure time of the i-th private parking space on the j-th day; i,j represents the return time of the i-th private parking space on the j-th day; FirstLeaveTime t and FirstReturnTime t The predicted departure time and the predicted return time of the t-th private parking space, respectively;

[0033] Or, the prediction result is calculated as:

[0034]

[0035] Among them, LeaveTime t,j represents the departure time of the t-th private parking space on the j-th day;

[0036] ReturnTime t,j represents the return time of the t-th private parking space on the j-th day;

[0037] SecondLeaveTime t and SecondReturnTime t The predicted departure time and the predicted return time of the t-th private parking space, respectively;

[0038] Or, the prediction result is calculated as:

[0039] ThirdLeaveTime t =α t FirstLeaveTime t +β t ·SecondLeaveTime t ;

[0040] ThirdReturnTime t =α t FirstReturnTime t +β t SecondReturnTime t ;

[0041] α t +β t =1;

[0042] Among them, α t and β t All are weights, ThirdLeaveTime t and ThirdReturnTime t are the predicted departure time and the predicted return time of the t-th private parking space respectively.

[0043] A private parking space corresponds to a pair of weights. The weight value of each private parking space is different.

[0044] As a further optimization of the above scheme, α t and β t The initial weight values ​​of are equal; the prediction module also includes optimization of the weights;

[0045] The calculation process is:

[0046]

[0047] in,(·) t , d represents the parameter corresponding to the t-th private parking space on the d-th day; d+1 represents the d+1-th day;

[0048] Get the actual departure time and return time of the t-th private parking space on the d-th day, and get the actual time period; according to FirstReturnTime t,d and FirstLeaveTime t,d Get the first time period; according to SecondReturnTime t,d and SecondLeaveTime t,d Get the second time period; FCLength t,dIt is the intersection time period of the actual time period and the first time period; SCLength t,d That is, the intersection time period of the actual time period and the second time period;

[0049] FirstCDR represents the first coincidence rate; SecondCDR represents the second coincidence rate;

[0050] α t,d+1 and β t,d+1 They all correspond to the weight of the t-th private parking space on day d+1; CF is the tuning threshold; LM is the minimum value of the weight.

[0051] CF and LM are both system preset values ​​and can be customized; by optimizing the weight values ​​of the two weights, the accuracy of the prediction results can be effectively improved.

[0052] As a further optimization of the above solution, the prediction module also calculates a compensation value to optimize the predicted departure time and the predicted return time; the calculation process is:

[0053]

[0054] Wherein, l represents the number of existing prediction results; (·) t , l represents the parameter corresponding to the t-th private parking space on the l-th day; FirstOffset and SecondOffset represent the first compensation value and the second compensation value respectively; ActLeaveTime and ActReturnTime represent the actual departure time and the actual return time respectively;

[0055] PreLeaveTime and PreReturnTime represent the predicted departure time and the predicted return time respectively.

[0056] By calculating the compensation value, the accuracy of the prediction result can be further improved.

[0057] As a further optimization of the above solution, the vehicle identification device includes a geomagnetic sensor; the geomagnetic sensor is arranged on each of the private parking spaces and is used to sense whether the private parking space is occupied by a vehicle.

[0058] As a further optimization of the above solution, the system further includes a communication module;

[0059] When the temporary vehicle is parked in the private parking space, and the time difference between the real time and the end sharing time is a preset time length, and the real time reaches the end sharing time, the communication module sends a reminder message to the second vehicle owner.

[0060] A reminder message is sent to the second car owner at a preset time in advance to avoid the private parking space being occupied due to the second car owner's overtime parking, and to ensure that the first car owner can park normally when returning to the parking lot.

[0061] Compared with the prior art, the present invention achieves the following beneficial effects:

[0062] (1) The system provided by the present invention is provided with a sharing module, which provides flexible sharing options for parking space owners, allowing users to customize designated time as idle time periods, so as to share private parking spaces during idle time periods, improve temporary parking services to the outside world, and ensure orderly management of parking space sharing;

[0063] (2) Through the map module, users can quickly locate and find vacant shared parking spaces, greatly simplifying the process of car owners looking for temporary parking spaces and reducing the time wasted due to not being able to find parking spaces;

[0064] (3) The system's car-moving robot can automatically intervene when a temporary vehicle occupies a parking space for an extended period of time and promptly move the vehicle to another vacant parking space, thereby protecting the normal use rights of the original parking space owner and avoiding potential disputes;

[0065] (4) Even if the user fails to manually set or forgets to set the idle time period, the system's prediction module can automatically and efficiently set the idle time based on the user's sharing habits, ensuring intelligent management of parking spaces;

[0066] (5) Parking space owners can also use their parking spaces to generate new income and reduce the cost of using parking spaces;

[0067] (6) By setting up a parking space sharing system, the user experience of sharing parking spaces can be effectively improved, which is also conducive to the promotion of the shared parking space management model and the implementation of other projects, and can effectively solve the problem of insufficient number of urban parking spaces and low utilization rate. BRIEF DESCRIPTION OF THE DRAWINGS

[0068] Figure 1 Schematic diagram of the system structure of the parking space sharing system provided in an embodiment of the present invention. DETAILED DESCRIPTION

[0069] In order to make the purpose, technical solution and advantages of the present invention more clear, the technical solution in the embodiment of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiment of the present invention. Obviously, the described embodiment is only a part of the embodiment of the present invention, not all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0070] Example 1

[0071] like Figure 1 As shown, this embodiment provides a parking space sharing system, which is applied to a parking lot; the parking lot is provided with private parking spaces, dispatch parking spaces and a car moving robot. A private parking space corresponds to an identification number and a license plate number, and the license plate number is used by the owner of the private parking space to bind the license plate number of the parking space; the identification number is used to uniquely identify the private parking space.

[0072] The parking lot is provided with a vehicle identification device, which is communicatively connected with the system; in this embodiment, the vehicle identification device includes a geomagnetic sensor and a camera.

[0073] A geomagnetic sensor is installed on each private parking space to sense whether the private parking space is occupied by a vehicle. The camera has a license plate recognition function. The parking lot is equipped with a gate at the entrance and exit, and the above-mentioned camera is installed at the entrance and exit of the parking lot.

[0074] The system includes a map module, a sharing module, a reservation module, a data collection module, a data storage module, a prediction module and a communication module.

[0075] The map module includes a public map outside the parking lot and a parking lot map; the parking lot map has specific layout information of private parking spaces and scheduled parking spaces, including location and orientation;

[0076] The detailed layout information also includes the status of private parking spaces; the status includes shared, occupied and reserved.

[0077] The data collection module collects the time when each first car owner leaves the parking lot and returns to the parking lot every day through the camera, which is recorded as the departure time and return time. That is, when the vehicle enters or exits the entrance, the camera will identify the vehicle license plate number and upload it to the data collection module for storage, while simultaneously recording the time. Based on the departure time and return time, it can be understood whether the first car owner's vehicle occupies a private parking space.

[0078] In this embodiment, the data storage module is provided with an entry and exit record table, and each record in the entry and exit record table includes an identification number, a license plate number, a departure time, and a return time and date.

[0079] The first car owner shares his private parking space during an idle time period through the sharing module; the idle time period includes a start sharing time and an end sharing time; one private parking space corresponds to one idle time period, and the idle time periods of all private parking spaces may be the same or different.

[0080] The first car owners referred to here usually refer to those parking space owners who drive their vehicles out of the parking lot during weekdays and other periods. The parking spaces of such car owners are often idle for a long period of time when their vehicles are not there, which provides the possibility of sharing parking spaces.

[0081] In this embodiment, when sharing a private parking space, the first car owner sets the start sharing time and the end sharing time through the sharing module;

[0082] Or the system automatically generates a start sharing time and an end sharing time for each shared private parking space. The prediction module predicts the departure time and the return time of each private parking space on each day according to the entry and exit record table to obtain the prediction result; the sharing module automatically generates a start sharing time and an end sharing time for the private parking space according to the prediction result; each record in the entry and exit record table also includes the prediction result.

[0083] First, the car owner can customize the sharing time period, or the system can automatically generate a sharing time period for any private parking space based on the management method of the parking lot; when both are used at the same time, the user-defined time period has a higher priority, that is, when the user does not customize the sharing time period, the sharing time period automatically generated by the system will be used by default; otherwise, the customized sharing time period will be used directly.

[0084] In this embodiment, the prediction results include the predicted departure time and the predicted return time;

[0085] The prediction result is calculated as:

[0086]

[0087] Where n is the number of private parking spaces, i∈[1,n]; m is the number of dates, j∈[1,m];

[0088] LeaveTime i,j ReturnTime represents the departure time of the i-th private parking space on the j-th day; i,j represents the return time of the i-th private parking space on the j-th day.

[0089]

[0090] Among them, LeaveTime t,j represents the departure time of the t-th private parking space on the j-th day;

[0091] ReturnTime t,j represents the return time of the t-th private parking space on the j-th day.

[0092] ThirdLeaveTime t =αt FirstLeaveTime t +β t ·SecondLeaveTime t ;

[0093] ThirdReturnTime t =α t FirstReturnTime t +β t SecondReturnTime t ;

[0094] α t +β t =1;

[0095] Among them, α t and β t are weights, α t and β t The initial weight values ​​of are equal, that is, they are all 0.5; one private parking space corresponds to a pair of weights. The weight value of each private parking space is different. t and ThirdReturnTime t are the predicted departure time and predicted return time of the tth private parking space respectively.

[0096] In this embodiment, the prediction module also includes optimization of weights; the optimization calculation process is:

[0097]

[0098] in,(·) t , d represents the parameter corresponding to the t-th private parking space on the d-th day; d+1 represents the d+1-th day;

[0099] Get the actual departure time and return time of the t-th private parking space on the d-th day, and get the actual time period; according to FirstReturnTime t,d and FirstLeaveTime t,d Get the first time period; according to SecondReturnTime t,d and SecondLeaveTime t,d Get the second time period; FCLength t,d It is the intersection time period of the actual time period and the first time period; SCLength t,d That is, the intersection time period of the actual time period and the second time period;

[0100] FirstCDR represents the first coincidence rate; SecondCDR represents the second coincidence rate;

[0101] α t,d+1 and β t,d+1 Both correspond to the weight of the t-th private parking space on the d+1 day; CF is the tuning threshold; LM is the minimum value of the weight. CF and LM are both system preset values ​​and can be customized; in this embodiment, CF is 0.1 and LM is 0.05. By optimizing the weight values ​​of the two weights, the accuracy of the prediction results can be effectively improved.

[0102] In this embodiment, for all calculations involving time, the data in time format is converted into a timestamp for calculation, and then the calculation result is converted into a time format.

[0103] For example, calculate ThirdLeaveTime t When α t , β t 、FirstLeaveTime t 、SecondLeaveTime t The values ​​are 0.5, 0.5, "2030-08-01 10:00:00", "2030-08-01 10:05:00";

[0104] The two time values ​​are converted into timestamps: 1911780000s and 1911780300s;

[0105] The calculation result is (0.5×1911780000+0.5×1911780300)=1911780150s, which is converted into the time format as "2030-08-01 10:02:30";

[0106] Assume that for the weight value after several adjustments, α t , β t They are 0.15 and 0.85 respectively; the calculation result is (0.15×1911780000+0.85×1911780300)=1911780255s, and the result converted into time format is "2030-08-01 10:04:15".

[0107] When a timestamp calculation result contains a decimal, it is rounded up. For example, 1911780300.1s is rounded to 1911780301s, and 1911780310.9s is rounded to 1911780311s.

[0108] When a vehicle is parked in a private parking space, the status is occupied; when no vehicle is parked in the private parking space and it is in an idle time period, the status is shared; in this embodiment, the second car owner makes a reservation for the private parking space in the shared status through the reservation module, and the status of the private parking space is changed from shared to reserved; or the second car owner directly locates the private parking space in the shared status according to the map module to park a temporary vehicle.

[0109] In this embodiment, when the temporary vehicle is parked in a private parking space, and the time difference between the real time and the end sharing time is a preset time length, and the real time reaches the end sharing time, the communication module sends a reminder message to the second vehicle owner.

[0110] A reminder message is sent to the second car owner at a preset time in advance to avoid the private parking space being occupied due to the second car owner's overtime parking, and to ensure that the first car owner can park normally when returning to the parking lot.

[0111] If a temporary vehicle is parked in a private parking space and exceeds the end time of sharing, the system controls the car moving robot to transfer the temporary vehicle to another private parking space with a shared status.

[0112] When transferring a vehicle, if all private parking spaces are occupied by vehicles, the temporary vehicle will be transferred to the dispatch parking space.

[0113] Dispatch parking spaces can only be used to transfer temporary vehicles already parked in the parking lot, and cannot be used as shared temporary parking spaces or private parking spaces. Dispatch parking spaces are set up as emergency backup to avoid the inability to dispatch temporary vehicles due to the lack of shared parking spaces, ensuring that vehicles have a place to park.

[0114] By sharing private parking spaces during idle time periods, the utilization rate of parking spaces can be effectively improved; at the same time, by sharing private parking spaces, owners of temporarily parked vehicles can be charged, forming a new revenue source for owners of private parking spaces, and the income generated can reduce the cost of purchasing and maintaining parking spaces; some temporary vehicles will occupy parking spaces for an extended period of time due to some subjective or objective reasons. When the sharing time ends, the temporary vehicles can be automatically moved away by a car-moving robot to ensure that private parking spaces are available in a timely manner and avoid occupation problems.

[0115] Example 2

[0116] Features not explained in this embodiment are explained in Example 1 and will not be described in detail here. The difference between this embodiment and Example 1 is that:

[0117] In this embodiment, the prediction module also calculates a compensation value to optimize the predicted departure time and the predicted return time; the calculation process is:

[0118]

[0119] Where l represents the number of existing prediction results; (·) t , l represents the parameter corresponding to the t-th private parking space on the l-th day; FirstOffset and SecondOffset represent the first compensation value and the second compensation value respectively; ActLeaveTime and ActReturnTime represent the actual departure time and the actual return time respectively;

[0120] PreLeaveTime and PreReturnTime represent the predicted departure time and predicted return time respectively.

[0121] By calculating the compensation value, the accuracy of the prediction result can be further improved.

[0122] According to the disclosure and teaching of the above description, those skilled in the art to which the present invention belongs may also make changes and modifications to the above embodiments. Therefore, the present invention is not limited to the specific embodiments disclosed and described above, and some modifications and changes to the present invention should also fall within the scope of protection of the claims of the present invention. In addition, although some specific terms are used in this specification, these terms are only for the convenience of description and do not constitute any limitation to the present invention.
