Embodiment
For making the object of the embodiment of the present invention, technical scheme and advantage clearly, below in conjunction with the accompanying drawing in the embodiment of the present invention, technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Fig. 1 is the schematic flow sheet of lookup method one embodiment of the present invention, and as shown in Figure 1, lookup method, comprising:
The information of vehicles of a car plate in step 101, acquisition distributed data base.
In the present embodiment, this distributed data base can be the distributed data base developed under Hadoop platform, and wherein, this Hadoop platform comprises the large data technique such as distributed file system, distributed computing framework, distributed data base.For example, this information of vehicles, at least comprises: car plate, sampling time and sampling position, and this information of vehicles does not limit at this, is only citing.
Step 102, according to described information of vehicles, determine whether described car plate exists fake license plate vehicle.
Concrete, the distance between the diverse location be at different time by the vehicle of same car plate, determines whether to exceed the maximal rate that vehicle travels, to determine whether this car plate exists fake license plate vehicle.Such as, it is 11111 that the first information of vehicles comprises license plate number, sampling time 2015-10-7; 5:00, railway station, Beijing, sampling position, it is 11111 that the second information of vehicles comprises license plate number; sampling time 2015-10-7; 5:10, railway station, Xi'an, sampling position, according to the distance between sampling position; and difference between the sampling time; the travel speed of this vehicle can be determined, thus determine that usual motor vehicles cannot realize this speed, and then determine that this license plate number is stored in fake license plate vehicle.
In the present embodiment, by obtaining the information of vehicles of a car plate in distributed data base; According to described information of vehicles, determine whether described car plate exists fake license plate vehicle.Achieve the information of vehicles obtaining same car plate from distributed data base fast, thus can determine whether this car plate exists fake license plate vehicle fast, and then improve the efficiency of searching fake-licensed car.
On the basis of above-described embodiment, before obtaining the information of vehicles of a car plate in distributed data base, also comprise:
By region predistribution function, described distributed data base is divided at least one region, and setting area mark, described area identification is for identifying the mark in described region, and described region is for storing described information of vehicles.
Optionally, area identification comprises license board information and sampling time information.
Further, on the basis of above-described embodiment, describedly by region predistribution function, described distributed data base is divided at least one region, and before the mark of setting area, also comprises:
The environment attribute information of distributed data base according to the ambient As of at least one server, described server is for storing described distributed data base.
Concrete, information of vehicles is loaded for HBase database, first, in the environment attribute information of distributed data base according to the ambient As of at least one server, and, create pre-importing HBase table name and row Praenomen, such as, the information that sets a property as zookeeper, wherein, described server is for storing described distributed data base, then, by region predistribution function, described distributed data base is divided at least one region, and setting area mark, such as, split function creation HBase table is write.The region region being represented distribution by 2-D data in split function, then, according to the design of assembly by the data genaration HFile file of information of vehicles, finally use completebulkload directly to complete data importing, this procedure ensures that efficiency and the area load equilibrium of data importing.
Further, according to the information of vehicles table of HBase database, write search fake license plate vehicle program by MapReduce framework.Rowkey in table is extracted in map function, the bayonet socket information of number plate of vehicle, time and process is obtained by Rowkey, according to time sequencing, calculating is carried out to the bayonet socket distance of vehicle and time and obtain speed per hour, and contrast F-Zero and whether can reach corresponding bayonet socket, if vehicle can not reach next bayonet socket when F-Zero, then show that this vehicle may be fake license plate vehicle, and export the relevant information of this vehicle.
