Detailed description of the invention

Further illustrate technical scheme below in conjunction with the accompanying drawings and by detailed description of the invention.

A kind of car plate fault-tolerance processing system, including terminal and server,

Step 1) vehicle rolls parking lot away from, and terminal carries out Car license recognition, finds to enter the record in parking lot without this vehicle;

Step 2) selection of the startup of server degree of approximation;

Step 3) server is by the vehicle entrance parking lot of record and without rolling the license board information in parking lot away from, according to the degree of approximation Sequence, and shown by the display module of terminal;

Step 4) carry out the judgement whether let pass, and operate.

Wherein, server, it is responsible for data acquisition and logical process.

Terminal, controls machine or main many auxiliary control machines for integral type, is located at the gateway in parking lot, has registration of vehicle Discrepancy information, open a sluice gate the functions such as clearance.Wherein, integral type control machine refer to one collect shooting, show, open a sluice gate the functions such as clearance in The parking lot gate of one;One-main-multi-auxiliary controls machine and refers to that in the multiple gate in same gateway, only one of which has control Circuit, other gate unifications are controlled by main switch machine.

Large parking lot typically has multiple gateway, and these setup of entrances and exits have terminal, and these terminal units are at vehicle Lower license plate number can be shot when entering parking lot, and license plate number information is sent to server, then just have the entrance of vehicle to believe Breath.Server can collect information of vehicles, and when vehicle parking lot to be rolled away from, terminal reads the number-plate number, if server finds nothing This vehicle enters the record in parking lot, then be probably terminal when vehicle sails into and misread license plate number, this is because software system meeting There is certain error.In order to not delay rolling away from of vehicle, now the management system in parking lot needs fault-tolerant mechanism, and as early as possible The license plate number information filtering out approximation in the data base of server is mated, thus lets pass for vehicle.

Preferably, car plate fault-tolerance processing system also includes the high in the clouds carrying out data backup.

Owing to the data volume of managing system of car parking is huge, terminal unit and server all can not carry the biggest data Amount, it is therefore desirable to high in the clouds carries out the backup of data.

Preferably, once the connection of server and terminal disconnects, then high in the clouds can temporarily take over server function and Being directly connected to terminal, at this moment high in the clouds starts logical process function.

Preferably, step 4) in the judgement whether let pass by manually carrying out or by threshold values control.

According to parking lot situation at that time, if the information of closest license plate number can not be immediately arrived at by threshold values, or Judge inaccurate, then can the most identical with the actual vehicle license plate rolled away to the car plate shown by display module by manpower comparing or Similar, thus carry out vehicle clearance.

Preferably, step 2) in the judgement of the degree of approximation include:

Step 1) different numerical digit weights are set;

Step 2) dynamically adjust;

Step 3) weighting (a);

Step 4) if a < threshold values, then it is judged as being correlated with.

Wherein, the computing formula that the degree of approximation judges is:

LA[i],B[i]=diff (A [i], B [i]) × w [i]

Wherein:

A represents " car plate A ";

B represents " car plate B ";

A [i] represents car plate i-th bit, such as " Guangdong E12345 ", and A [1] is " Guangdong ", and A [2] is " E ", and A [3] is " 1 ", with this Analogize;

W [i] represents the similarity of car plate i-th bit and accounts for the weighted value of whole car plate similarity, the most easily identifies the car of mistake Memorial tablet number, weighted value is the lowest;

LA,BRepresenting similar point of car plate A and car plate B car load board, license plate number is the most similar, and its similar point the lowest;

LA[i],B[i]Represent car plate A i-th bit and similar point of car plate B i-th bit;

Diff (A [i], B [i]) represents car plate A i-th bit and car plate B i-th bit discrimination score value, and similarity is the highest, and score value is more Low.Discrimination score value such as " B " and " 8 " is low, and the discrimination score value of " T " and " 0 " is high.When two positions are just the same, discrimination is 0。

The following is embodiments of the invention, it is judged that target license plate A " Guangdong E12345 " and contrast car plate B " Guangdong F12346 " and right Than car plate C " Guangdong E12L45 ", which is more like.

Step 1) weights of different numerical digit are rule of thumb set: w [1]=0.1, w [2]=0.1, w [3]=0.2, w [4]= 0.2, w [5]=0.2, w [6]=0.1, w [7]=0.1;

Step 2) the most dynamically adjust: diff (E, F)=1, diff (5,6)=1, diff (3, L)=3;

Step 3) contrast weighted value between car plate A and car plate B, car plate C:

a)LA,B=0+0.1+0+0+0+0+0.1=0.2

b)LA,C=0+0+0+0+0.6+0+0=0.6

Therefore, although car plate B has two characters inconsistent with car plate A, and it is inconsistent with A that car plate C only has a character, but root According to similarity algorithm, between car plate A and car plate B, weighted value is lower, more like.So, in the display screen at EXIT, Car plate B can come and show before car plate C.
