In conjunction with Fig. 2, the embodiment of the present invention also provides a kind of highway shipping that can be applied to above-mentioned terminal device 10
Vehicle transprovincially matching process, the method includes the steps seven steps of S110- step S170.
Step S110: the entry data and outlet data of the corresponding goods stock of charge station transprovincially prestored are obtained, is based on
The matching degree of the license plate number in license plate number and entry data in the outlet data includes matched data and non-matched data
Sample data.
Wherein, the mode of the entry data and outlet data that obtain the corresponding goods stock of charge station transprovincially prestored can be with
It is the corresponding charge station's information in national freeway toll station position and Provincial administrative division boundary inputted according to user
As charge station's information transprovincially, and transprovincially corresponding outlet data and the entry data in charge station's information is obtained, is also possible to
Charge station's information transprovincially is obtained according in the high speeds highway network topological structure such as Amap and Tencent's map, and obtains this and transprovincially receives
Take the entry data and outlet data of the corresponding goods stock of station information.
It is optionally, in the present embodiment, described to obtain the corresponding goods stock of charge station transprovincially prestored incorporated by reference to Fig. 2
Entry data and outlet data, matching degree based on the license plate number in the license plate number and entry data in the outlet data is raw
At including the steps that the sample data of matched data and non-matched data includes:
Step S112: it is obtained transprovincially according to freeway net topological structure, charge station location and provincial administrative area boundary
Charge station's information, and obtain the goods stock outlet data corresponding with the information of charge station transprovincially and entry data prestored.
Step S114: have the corresponding outlet data of complete license plate number as target outlet data in outlet data, adopt
With preset algorithm from the entry data search with the complete license plate number in the target outlet data consistent and outlet data
In time and entry data in the difference of time be located at the entry data of a setting time range as target entries data,
And using the target entries data and with the target outlet data of the target entries Data Matching as matched data, by other data
As non-matched data.
It should be noted that in the present embodiment, the charge station transprovincially can be out inbound fission, it is also possible to enter and leave
Stand one, when it is described go out inbound fission when, the distance between the outlet station of the charge station transprovincially and access station should one compared with
In short distance range, such as in 20,30 or 40 kilometers.
The preset algorithm can be JaroWinkler Distance algorithm, be also possible to Levenshtein
Distance algorithm, is chosen according to actual needs, is not specifically limited herein.
Optionally, in the present embodiment, it is searched from the entry data using preset algorithm and the target outlet number
The difference of time of the complete license plate number in unanimously and in time and entry data in outlet data is located at a setting time
The entry data of range is as target entries data, and by the target entries data and target with the target entries Data Matching
Outlet data includes: as matched data, using other data as the step of non-matched data
License plate number L in outlet data is calculated using JaroWinklerDistance algorithmOutletWith the vehicle in entry data
Trade mark LEntranceSimilarity Slicense:
Slicense=Sj+(lp(1-Sj))
