Description
Technical field
The invention belongs to electronic license plate technical fields, more particularly, to a kind of electronic license plate ambiguity implementation method.
Background technique
Traditional Path Recognition mode is Car license recognition method, highway entry and exit be arranged license plate capturing system (or use
License plate number is manually entered), Vehicle License Plate Recognition System is arranged as beacon station in ambiguity section in road network, and what be will identify that is logical
The license board information of driving is uploaded to background system, in expressway exit, passes through beacon station by system queries vehicle midway
License plate record, three kinds of entrance, outlet, section license board informations are compared, determine the route of vehicle actual travel, pickup vehicle is logical
Row takes, and in this, as the foundation of split balance.Car license recognition method is a kind of relatively accurate identification method, may be implemented not stop
The ID of trace route path of vehicle, to realize expressway tol lcollection and fee distribution based on accurate path.
But realize that multipath differentiates that there is also some problems based on Car license recognition.Firstly, license plate identification accuracy by
Rain and snow weather, visibility it is high it is low be affected, trick-plate is stained and the number plate true and false can not recognize, especially for unlicensed
The problem of vehicle, false fake-licensed car, is helpless, however it remains changes the administrative vulnerabilities such as licence plate fee evasion.Secondly, Car license recognition need to pass in real time
The data volume of the information of defeated license plate, transmission is larger, requires transmission network and data-handling capacity is higher, and Car license recognition
The whole construction cost of system is higher.In order to solve the problems in Car license recognition method, it is complete to need to find a kind of more suitable method
At the accurate identification of information of vehicles, guarantee the accurate differentiation and management of vehicle running path with this.
Summary of the invention
In view of this, the present invention is directed to propose a kind of electronic license plate ambiguity implementation method, is held with solving existing license plate
It is influenced vulnerable to ambient weather, the problem of appearance can not recognize.
In order to achieve the above objectives, the technical scheme of the present invention is realized as follows:
A kind of electronic license plate ambiguity implementation method, comprising:
S1, license plate recognition device is built at path inlet, and the license board information of identification is sent to automobile management system
The cloud server at center；
S2, path identification station is set on section, license plate recognition device is set in path identification station, passes through the vehicle on section
The license board information for the vehicle that the identification of board identification device is passed through, and the information of license board information and the Path Recognition station is sent to cloud
Server；
S3, license plate recognition device is built at path outlet, and the license board information recognized is sent to cloud server.
Further, the license plate recognition device is view radio frequency all-in-one machine, and described depending on radio frequency all-in-one machine includes video identification
Unit and radio frequency identification unit；
The video identification unit includes camera and image processing module, is believed by the license plate that camera captures automobile
Breath, and the picture taken is handled by image processing equipment, license board information is extracted, and the information is sent to cloud clothes
Business device；
The radio frequency identification unit includes RFID tag and RFID label tag module for reading and writing, for the automobile group each driven into
Send out RFID tag unique, by identifying depending on the radio-frequency module of radio frequency all-in-one machine to RF tag, and by the radio frequency mark
It signs corresponding information of vehicles and is sent to cloud server.
Further, in the step S1, when vehicle drives into section entrance, by video identification unit and radio frequency identification unit
License plate is identified simultaneously, if recognition result is inconsistent, determines the illegalities of vehicle, and right in vehicle management system
The automobile is identified and alerts；If recognition result it is consistent or determine it is legal after, by the unique identification information of vehicle, lane
Number, drive into the time and be uploaded to cloud server.
Further, the cloud server is that each vehicle driven into establishes storage region, and each vehicle is corresponding to be deposited
Storage area domain includes vehicle unique identification information area, trough, the ID of trace route path information area；
Vehicle unique identification information area is used to store the information of vehicles of corresponding vehicle, including license board information；
The ID of trace route path information area is used to store the information of the path identification station of vehicle process, by determining that vehicle passes through
Path identification station information determine the driving path of vehicle；
Further, in the step S2, each path identification station includes multiple view radio frequency all-in-one machines, and cloud server connects
It after the information for receiving the upload of Path Recognition station, needs to handle information, to guarantee each Path Recognition station identification vehicle
Uniqueness.
Further, the information that cloud server uploads path identification station, process flow are as follows:
The storage of path identification station information is set as unit of a word, low byte store path beacon station information is high
Bit byte stores 0x00 and judges path identification station information according to the storage region information in the vehicle of reading beyond the clouds server
Whether area is full 0, if it is full 0, then proves that the path identification station is first beacon station of vehicle pass-through, the beacon station is written
Encoded information, if the non-full 0 in the beacon station information area, it was demonstrated that the beacon station is not first beacon station of vehicle pass-through, is then sentenced
Whether the last one non-zero byte information content of breaking is the beacon station encoded information, if it is, proving to write this by read-write equipment
Beacon station information avoids being repeatedly written it is not necessary that beacon station information is written again；If the last one non-zero byte information content is not
It is for the beacon station encoded information, it was demonstrated that the beacon station information does not carry out storage operation also, need to store beacon station encoded information, first
First judge whether the last one non-zero byte is odd number bit byte, if it is, by the non-zero byte read and the beacon station
Information is combined into 1 word, covers current non-zero byte location, the beacon station encoded information an of word is written；If the last one is non-
0 byte is not odd number bit byte, is even bit, then the beacon station information and 0x00 is combined into 1 word, is written to non-zero word
Next word after section, to complete the write-in of beacon station information.
Further, in the step S3, the vehicle identifier in section exit by information of vehicles, lane number, be driven out to
Time is uploaded to cloud server.
Compared with the existing technology, electronic license plate ambiguity implementation method of the present invention has the advantage that
Electronic license plate ambiguity implementation method of the present invention stores road management system according in cloud server
Information the pipe such as determine arcuate path that vehicle travels in the road interval, and then charged, detected to vehicle, counted
Reason；And it, can be according to the actual situation by this path segment of the vehicle in cloud server after information of vehicles is applied
Interior information persistence or deletion.
