Technical Field

[0001] The present invention relates to the technical field of vehicle management, and more particularly to a parking lot vehicle management system. Background Art

[0002] With the development of technology, more and more parking lots are beginning to use intelligent management systems. The current parking lot vehicle management system can intelligently count the parking situation of vehicles in the parking lot, and can intuitively let car owners know the remaining parking spaces in the parking lot. However, the current parking lot vehicle management system cannot recommend suitable parking locations to car owners based on their parking habits, which leads to crowded parking in some areas of the parking lot and no parking in some areas. Summary of the invention

[0003] In view of the deficiencies in the prior art, an object of the present invention is to provide a parking lot vehicle management system.

[0004] To achieve the above object, the present invention provides the following technical solutions:

[0009] The time difference between the vehicle exit time and the vehicle entry time recorded in the same vehicle and stop record is calculated to obtain the same vehicle and stop duration, and each same vehicle and stop duration is set to correspond to a standard same vehicle and stop duration. When the same vehicle and stop duration is less than the standard same vehicle and stop duration, the same vehicle and stop duration is marked as a low-standard same vehicle and stop duration, and a low-standard same vehicle and stop value Ec is obtained. When the same vehicle and stop duration is greater than or equal to the standard same vehicle and stop duration, the same vehicle and stop duration is marked as a high-standard same vehicle and stop duration, and a high-standard same vehicle and stop value Sq is obtained.

When the same-vehicle-and-parking value Fh<the same-vehicle-and-parking threshold Wz, no processing is performed;

When the key parking value Jk ≥ the key parking threshold Sf, the grid area is marked as a pause area, and the grid area not marked as a pause area is marked as a target area. When the key marked vehicle enters the parking lot, the entry guidance module sends the location of the final selection area to the mobile terminal of the parking lot manager, and the parking lot manager guides the key marked vehicle to the final selection area for parking.

[0012] Furthermore, the vehicle parking record includes the license plate number, vehicle entry time, vehicle exit time, and vehicle parking area.

[0014] Furthermore, the low-standard same-stop value Ec is obtained by the following steps: the standard same-stop duration is calculated to be different from the low-standard same-stop duration to obtain the low-standard same-stop time difference Fi, and the low-standard same-stop time difference coefficient is set to Wp, p=1, 2, 3, ..., p; W1<W2<W3<...<Wp, and each low-standard same-stop time difference coefficient is set to correspond to a range of low-standard same-stop time difference, including (0, F1], (F1, F2], ..., (Fi-1, Fi], when Fi∈(0, C1], the corresponding low-standard same-stop time difference coefficient is W1, and the formula is used Get the low-standard time difference By, where i is the number of times the same vehicle and the same stop time are marked as the low-standard same stop time, sort the vehicle entry times corresponding to the low-standard same stop time in chronological order, calculate the time difference between the two adjacent vehicle entry times after sorting, and get the low-standard same stop interval, sum up all the low-standard same stop intervals and take the average, get the average low-standard interval, and mark it as Dk; use the formula The low-standard stop value Ec is obtained, where b1 is the low-standard time difference coefficient and b2 is the average low-standard interval coefficient.

[0015] Furthermore, the high-standard same-stop value Sq is obtained by the following steps: the high-standard same-stop duration is calculated to be different from the standard same-stop duration to obtain the high-standard same-stop time difference Cj, and the high-standard same-stop time difference coefficient is set to Zb, b=1, 2, 3, ..., b; Z1<Z2<Z3<...<Zb, and each high-standard same-stop time difference coefficient is set to correspond to a range of high-standard same-stop time difference, including (0, C1], (C1, C2], ..., (Cj-1, Cj], when Cj∈(0, C1], the corresponding high-standard same-stop time difference coefficient is Z1, and the formula is used The high-standard time difference Dt is obtained, j is the number of times the same vehicle stops at the same time and is marked as the high-standard same-stop time. The vehicle entry times corresponding to the high-standard same-stop time are sorted in chronological order, and the time difference between the two adjacent vehicle entry times after sorting is calculated to obtain the high-standard same-stop interval. All the high-standard same-stop intervals are summed and averaged to obtain the average high-standard interval, which is marked as Yg. Using the formula The high-standard stop value Sq is obtained, where c1 is the high-standard time difference coefficient and c2 is the average high-standard interval coefficient.

[0016] Furthermore, the same-car-and-same-stop value Fh is obtained by the following steps: Using the formula The same-car same-stop value Fh is obtained, where d1 is the average same-stop interval coefficient, d2 is the low-standard same-stop value coefficient, and d3 is the high-standard same-stop value coefficient.

[0017] Further, the key parking value Jk is obtained by the following steps: obtain the number of times the same grid area is marked as a key parking area every day within 30 days before the current time of the system, and mark it as the number of single-day remarkings, set the single-day remarking threshold to Gh, when the single-day remarking number ≥ the single-day remarking threshold Gh, mark the single-day remarking number as the reference remarking number, and mark the corresponding date as the reference remarking date, sum up all reference remarking times, obtain the reference remarking total number, and mark it as Dg, sort all reference remarking dates in chronological order, calculate the time difference between the two adjacent reference remarking dates after sorting, obtain the reference remarking interval, sum up all reference remarking intervals and take the average, obtain the reference remarking average interval, and mark it as Ry, use the formula The key parking value Jk is obtained, where e1 is the reference re-marking total times coefficient, and e2 is the reference re-marking average interval coefficient.

[0018] Furthermore, the position of the final selection area is obtained through the following steps: on the basis of the same time interval, the number of vacant parking spaces in the target area is continuously detected, and the threshold value of the number of vacant parking spaces is set to Bn. When the number of vacant parking spaces is less than the threshold value of the number of vacant parking spaces Bn, the number of vacant parking spaces is marked as a low-value number of parking spaces, all low-value numbers of parking spaces are summed and averaged to obtain the average low-value number, which is marked as Ew, all low-value numbers of parking spaces are sorted in the order of corresponding detection time, and the time difference between the two adjacent detection times after sorting is calculated to obtain the low-value parking space interval, all low-value parking space intervals are summed and averaged to obtain the low-value parking space average interval, which is marked as Fu, and the target area value Qz is obtained using the formula Qz=Ew×f1+Fu×f2, wherein f1 is the average low-value number coefficient, and f2 is the low-value parking space average interval coefficient, and the target area with the largest target area value Qz among all target areas is marked as the final selection area.
