It applies among a range.
Embodiment 1
A kind of screening technique of shops that hires a car is present embodiments provided, as shown in Figure 1, the screening technique for the shops that hires a car includes
Following steps:
S1, the request of hiring a car for receiving user.
When user needs to rent vehicle, the available shops that hires a car of current address is searched in APP, system receives the rent of user
Vehicle request, and carry out subsequent processing.
S2, the address for obtaining user.
Hiring a car when requesting for user is received, the current address for receiving user is synchronized.
S3, judge that process finds out the shops that hires a car to match with the address of user using first.
It includes following step that wherein step S3, which judges that process searches the shops that hires a car to match with the address of user using first,
It is rapid:
S31, the address for obtaining the shops that hires a car in database.
First judges all shops that hire a car in requirements of process ergodic data library, hires a car in database so circulation successively obtains
The address of shops.
S32, the address based on the shops that hires a car generate the shops that hires a car and provide the first square region of service covering.
There are multiple coverages such as 2 kilometers of service areas, 3 kilometers of service areas, chargeable service area in the shops that hires a car in APP, and
And these coverages are since the limitations such as road, landform may be irregular polygon, 1 He of coverage as shown in Figure 2
Coverage 2, X-axis represents longitude in figure, and Y-axis represents latitude.It is irregular more whether the address of directly calculating user falls into these
The service range of side shape composition, algorithm is complicated and calculation amount is huge, thus the shops that hires a car address surrounding mark one it is rectangular
Region takes the extreme value of the longitude and latitude of each coverage for the shops that hires a car, such as the minimum longitude of the midpoint Fig. 2 A, the minimum latitude of point B
First square region of the maximum latitude composition of degree, the maximum longitude of point C and point D, so that it may rapidly filter out the ground of user
Location is located at the shops that hires a car in the first square region of the shops that hires a car.
As shown in figure 3, the step S32 for generating the first square region includes the following steps:
S321, the multiple coverages for obtaining the shops that hires a car；
The hire a car coverage of shops is stored in database, needs the used time that can directly read from database.
S322, acquisition hire a car shops each coverage longitude and latitude range, the longitude and latitude from all coverages
Maximum longitude, minimum longitude, maximum latitude value and minimum latitude value are obtained in range, by the maximum longitude, described
Minimum longitude, the maximum latitude value and the minimum latitude value as the maximum longitude of the first square region, minimum longitude,
Maximum latitude and minimum latitude, so that it is determined that the first square region.
In practical operation, in order to reduce the user query time, step S32 generates the shops that hires a car based on the address for the shops that hires a car
The first square region for providing service covering can be fulfiled ahead of schedule by system.One timed task of default, timing acquisition data
The address of all shops that hire a car in library generates corresponding first square region in address for the shops that hires a car, and database is stored in, in user
The inquiry used time can be greatly reduced when inquiry.
S33, judge whether the address of user falls into the first square region, if the then corresponding door of hiring a car of the first square region
Shop and the address of user match；
The algorithm comparison for judging whether an address falls into a square region is simple, for example determines the warp of lower square region
Maximum value and minimum value, latitude maximum value and minimum value are spent, as long as comparing then carrying out two simple numberical ranges, i.e. address
Longitude whether fall between the longitude maximum value of square region and minimum value and whether the latitude of address falls into square region
Between latitude maximum value and minimum value, when determining all to be it is determined that the address falls into the square region.Numeric ratio
Fast compared with arithmetic speed in a computer, shops's progress of hiring a car in ergodic data library is such shorter than relatively time-consuming, can filter out
Closest to shops's list of hiring a car of service can be provided for station address, greatly reduces to accurately calculate station address and whether fall into and hire a car
The calculation amount of shops's service range improves arithmetic speed.
As shown in figure 4, judging whether station address falls into the step 33 of the first square region and include the following steps:
S331, the longitude coordinate and latitude coordinate for obtaining station address；
Receive user hire a car request when in the station address received obtain station address longitude coordinate and latitude
Spend coordinate.Then it respectively enters step S3321 and step S3322 is judged.
S3321, judge whether the longitude coordinate of station address falls into the minimum longitude and maximum longitude of the first square region
Between, the longitude coordinate of station address meets the requirements when the judgment is yes.
S3322, judge whether the latitude coordinate of station address falls into the minimum latitude and maximum latitude of the first square region
Between, the latitude coordinate of station address meets the requirements when the judgment is yes.
S333, when step S3321 and step S3322 is judged as YES, i.e., when the longitude coordinate of station address and latitude
When coordinate meets the requirements, it is determined that the address of the user falls into the first square region, i.e., the first square region is corresponding hires a car
Shops and the address of the user match, which is added in the shops's list of hiring a car to match with the address of user.
First judges process S3 by abovementioned steps, has judged whether the shops that hires a car matches with the address of user,
Enter step S34:
Whether S34, the shops that judges to hire a car in database have arrived last one, if otherwise return step S31 continues to execute step
Rapid S31~S34, until hiring a car in database, the last one shops, shops is finished, if then continuing to execute step S4.
After the shops's list of hiring a car to match with the address of user has been determined, the present embodiment, which continues to execute, calculates step S4,
Wherein S4 the following steps are included:
The multiple coverages for the shops that hires a car that S41, acquisition and the address of user match；
It hires a car in shops's list basis what step S1~S3 was obtained with what station address matched, needs successively to judge to use
Whether the address at family falls into list any one coverage for the shops that each hires a car, so needing to be traversed for and station address phase
Matched shops's list of hiring a car.Here hire a car multiple coverages of shops are exactly foregoing multiple irregular polygon
Shape.
S42, calculate user address whether fall into and hire a car shops any one coverage in, if so then execute step
Rapid S43, thens follow the steps S44 if not.
Calculating address and whether falling into an irregular polygon is a mature algorithm, can be called directly, still
This calculating process is more complicated, takes a long time, so needing to be screened by step S3, reduces need using this as far as possible
The calculating process of algorithm improves search efficiency.
If S43, then push hires a car shops to user.
Station address falls into any one coverage for the shops that hires a car, then this is hired a car, shops can be pushed to use
Family, with for reference.
Whether the shops that hires a car in shops's list that S44, judgement and station address matched hire a car has arrived last one, if not
Then return step S41 continues to execute step S41~S44, until last in the shops's list of hiring a car to match with station address
A shops is finished, if then terminating process.
The present embodiment sends the address that request of hiring a car only uses user in user, whether falls into one using the longitude and latitude of address
The simple algorithm of a square region quickly filters out the shops's list of hiring a car to match with the address of user, reduces the door inquired
Shop amount of redundancy, reduces whether calculative station address falls into complicated calculations amount as the service range of shops of hiring a car, and mentions
